An indoor shooting range is a closed room, which is especially designed in its construction and equipment for the training of the real shoot under realistic conditions. To ensure maximum safety for the trainees and their instructors in learning the save handling of loaded weapons or periodic control exercises, it is necessary to give special attention on the construction of partially tiny details. This applies both to the specific wall and ceiling structures and for the most for the user invisible but highly safety-relevant components behind the visible acoustic panels.
Our company has more than twenty years experience in the construction of shooting ranges the necessary know-how, to find always the optimal an also economical solution for the customer, even in not quite trivial requirements.
Our service portfolio spreads along from creating detailed construction planning’s, on the production of safety-related, bullet-resistant constructions to the final interior design of indoor shooting ranges and their associated bullet traps and bullet-resistant windows and doors.
Through an increasing optimization of ventilation systems, the geometry of the shooting range has changed fundamentally. Here, the usual wall and ceiling structures have been further developed. So the usual on the walls wooden slats and the characteristic the sawtooth ceiling has been changed to modern, smooth constructions.
Bullet-resistant constructions are safety components that are tested through its paces by a certified testing center for their bullet-proof property . They serve mainly to protect people who are located in the adjacent rooms to the indoor shooting range .
Our bullet-resistant window and door structures are available in different fire classes. We are sure to offer the appropriate window or door suitable for your
The snail bullet trap „Kassler snail“ needs an installation depth of approx. 4300 mm (plus servicing way) and has a construction height of 2800 mm (plus assembly distance). In the width the bullet trap is made individually on measure and the support structure needs on both sides approx. 200 mm. Widths of 6500 mm were already realised.
The snail bullet trap can be produced according to requirement in different steel qualities and material strengths. Mainly highly wear-resistant special steels, so-called "wear plates" are used, as for example Hardox 400 or Hardox 500. According to requirement the material strengths of the collision plates and the snail are realised with measures between 5 mm and 15 mm, whereas the snail is rolled and formed up to a strength of 10 mm. Strengths more than 10 mm are realised by polygonal edges.
The bullet hits on the funnel-shaped collision surfaces which are lengthwise collision-free and is deflected in the direction of the rear snail. No bullet decomposition (dependent on ammunition) occurs due to the flat angle of attack (approx. 20 °). The special, shifted arrangement of both half bowls forces the bullet at the stage of entry into the snail into a circular flight path and diminishes the bullet energy in the process. The slowed down bullets fall through a lower opening of the snail in push boxes or on a conveyor belt. The complete snail is dust-protected to the end and the dust can be sucked off safely by a suction support along the complete width. The construction is protected by utility models.
The bullet trap exists of a supporting framework (HEB, HEA and IPE S235JR) which is preferentially put up on the ground decoupled from mechanical vibration of adjoining components. Upper and lower collision plates (thickness and quality according to requirement) are hung up at a sloping angle (approx. 20 °) into this construction and are secured covertly. These form a funnel which is closed on both sides also with collision plates. These measures escort the bullet safely into the back end of the bullet trap. It forms the essential snail that consists of two shifted half bowls (diameter approx. 750 mm) in which the bullet peters out in several rotations and is collected afterwards in a “bullet collector” which is described in the following section. Should bullet fragments still not reach the snail, these are collected in a catch basin which is located at the bottom of the lower collision plate. For the removal of the accruing dust a vacuum is generated in the snail by which the accruing dust is pulled into the snail by the funnel. Therefore, the snail is closed in itself and can pull air merely via the funnel.
There are two kinds of bullet collection devices to choose from. On the one hand, there is the possibility to catch the bullet leftovers in push boxes which can be pulled out to the rear with the cleaning routine and emptied afterwards. On the other hand there is the possibility to carry the bullet leftovers by a automatically timed band conveyor in a collective box which can be changed comfortably by a servicing door arranged beside the bullet trap by means of lifting cart. As a result of this the shutdown times can be reduced to a minimum. Besides no injurious dust which jeopardises the health of the maintenance staff is whirled up with this kind of the bullet disposal. For the check of the conveyor belt an access possibility should exist behind the bullet catch.
The steel blade bullet trap V4 needs a depth of 350 mm plus splinter protection. Hereby it belongs to the flattest bullet traps. In the width and height the dimensions can be adapted individually to the local circumstances, whereas a grid measure of 1000 mm in the width is to be considered as optimum. The remaining rest width is closed by a matching protection.
The steel blade bullet trap can be produced according to requirement in different steel qualities and material strengths. Particularly highly wear-resistant special steels, so-called "wear plates" are used, as for example Hardox 400 or Hardox 500. According to requirement the material strengths of the frame and the blades are realised with measures between 10 mm and 15 mm. Stronger thicknesses are possible on request.
In front of a vertical steel plate wall (back wall) blades are arranged Venetian blind-like, horizontally under an inclination of 30 ° to 45 °, so that the striking bullets are deflected to the back below. Between the blades and the back wall remains a gap into which the deflected bullets can fall down. The number of horizontal blades respectively the vertical distance of each other and the respective inclination corner is chosen adapted to the range so that a direct bombardment of the back wall is not possible. To the sides the construction is closed by vertically standing steel plates (stand) which contain special cuttings to allow the inclusion of the blade support. As a specific feature the blade storage protected under patent law is to be emphasised which allows a form-logical connection of the support in the stand. The unavoidable dilution of the steel quality by welding in the support structure is prevented hereby.
To exclude as much as possible the danger by ricochets, the supports were optimised geometrically especially for this purpose, so that striking bullets are certainly derived in the direction of the rear bullet trap wall. Moreover, the front edge of each blade pointing to the shooter and those of the stands at the top or front in shot direction are bevelled in rear direction under a degree of 45 °. This bevelling is produced by a special cold treatment (not thermally like burning). This causes only a minor loss of the material quality to be neglected. Another advantage of the blade storage protected under patent law is the possibility to exchange worn blades and editions with easy means without specialist knowledge. The complete bullet trap is delivered with a work-sided Primer as standard. On request a coloured painting to prevent corrosion is possible, however, not necessarily required.
There are two kinds of bullet collection devices to choose from. On the one hand, there is the possibility to catch the bullet leftovers in push boxes which can be pulled out to the front with the cleaning routine and emptied afterwards. To prevent ricochet shots the push boxes are battened down front-sided with softwood treated according to German Institute for Standardization DIN 4102 – B1 and with elastic fibre plates. On the other hand there is the possibility to collect the bullet leftovers in a helical chamber which can be exhausted by a front flap with the regularly scheduled cleaning or can be sucked out. This front is protected effectively against bouncing during the shooting by the coverage with an elastic fibre block.
Furthermore, there is the possibility of automated bullet extractor , in which the projectile residues are conveyed by a belt transporter system to a central collecting box , which can be changed easily . So it is possible to minimize the maintenance downtimes. In addition, this type of projectile discharge has occupational health benefits because of the direct contact of the maintenance personnel with the projectile remains unnecessary.
Striking bullets penetrate a thermoplastic backing layer and are safely slowed down by a granulate material filling behind it. The canal originated by the bullet uses itself almost completely up on account of the high elasticity of the backing layer.
The bullet trap system Thermowall consists of a 100-mm-thick Backing layer by standard and chamber system which rejuvenates upwards. The depth of the chamber system is dependent on the bullet energy. For example, a bullet trap for a bullet energy of up to 1500 joules shows a whole construction depth of 550 mm. With higher bullet energy the construction depth increases accordingly. In width and height the bullet trap can be produced in the individually desired dimensions. As a location outdoor and indoor shooting ranges are possible, because the bullet trap system was developed for operation in temperature ranging from -24 ° C to + 60 ° C. Besides, no noise and dust emissions originate while bullets are striking, which is why the bullet trap system does justice to the demands of the environment protection for outdoor ranges in particular.
The 100-mm-backing layer by standard consists of an especially adjusted Copolymerise which shows an excellent restoration capability. Normally blocks are produced in the size of approx. 445 mm by 445 mm which form the backing layer lined up smoothly together without gap. Worn blocks can be recycled completely by a sophisticated recycling procedure and be processed to new blocks.
Vertical ribs combine into a firm grid cell system in connection with a back wall. Preferred materials are mainly 5-mm highly wear-resistant special steels, so-called "wear plates", as for example Hardox 500. 100-mm-ashlar-shaped blocks are lined up in and about one another without joint in front of this chamber system and are fortified on the back side. In addition, the joints are treated thermally on the front side, so that a closed backing layer originates. In the cavity between the ribs, the back wall and the backing layer a special granulate filling to reduce the energy of the bullets is introduced in which the bullets remain up to the next servicing.
Striking bullets are slowed down in the granulate filling and remain here until the next servicing. This obviously generates an enlargement of volume behind the backing layer. Due to the increasing volume of the granulate material and bullet mixture the backing layer is pressed forward and forms a "belly". When the maximum capacity is reached the push joints of the backing layer burst bit by bit, so that sporadically granulate material escapes. By no later than now a servicing must be carried out. This can be carried out by our experienced servicing team or your own staff. On this occasion, a part of the backing layer is dismantled and worn blocks are exchanged for new respectively recycled blocks. The granulate material is separated nearly without loss from the bullets and is filled in the chamber system for further use, once the backing layer has been rebuilt
