Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil defense wall technology, and in particular to a civil defense explosion-proof wall that can be quickly assembled and disassembled. Background Technology
[0002] Explosion-proof walls refer to walls with strong resistance to explosion pressure, also known as blast-resistant walls or explosion-proof walls, and are often installed in factories or warehouses with explosion hazards. In civil defense facilities, explosion-proof walls naturally become an indispensable protective barrier to ensure personnel safety. An existing civil defense explosion-proof wall with application number CN201720851227.6, which can be quickly assembled and disassembled, includes unit walls. Each unit wall consists of a concrete layer and steel plates set within the concrete layer. One end of the steel plate along the length of the concrete layer has an insert plate, and the other end has a slot… By inserting the insert plate and slot, the unit walls are connected along their length to form vertical columns. Multiple vertical columns are connected along the width of the unit walls using H-beams. Since the above structural connection method is all plug-in, operation is convenient, thus achieving the effect of rapid installation of the civil defense explosion-proof wall. However, this civil defense explosion-proof wall requires the insertion of several first and second fixing pins during installation, and several first and second fixing pins need to be pulled out during disassembly, making installation and disassembly not fast enough. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies in terms of slow installation and disassembly, and to propose a rapid-installation and disassembly-resistant civil defense and explosion-proof wall.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a quick-assembly and detachable air-raid shelter wall, comprising unit walls and H-beams. Several rows of unit walls are vertically stacked, with H-beams between adjacent rows. Both ends of each unit wall are inserted into slots at the top and bottom of the H-beams. The back of each H-beam has several reinforcing ribs, and each unit wall has one reinforcing rib on its back. The front end of the flat plate of each reinforcing rib has several pairs of circular holes, and each pair of holes has a fixing pin. The front end of each pair of fixing pins passes through the corresponding unit wall and H-beam and extends to the front of the H-beam. The front end of each H-beam has a front guard plate, and the front end of the front guard plate has slots corresponding to the pairs of fixing pins. The top of the front end of each fixing pin has a snap-fit groove, and the front guard plate slides into the snap-fit groove. The rear end of each fixing pin has a rotating device. The interior of each unit wall has a steel plate penetrated by the fixing pins.
[0006] Preferably, the H-beams that are adjacent vertically are staggered by the width of two unit walls in the horizontal direction.
[0007] Preferably, the front end face of the H-beam is provided with a mounting groove, and a spring piece is fixed in the mounting groove, the spring piece being located in the slot.
[0008] Preferably, the outer wall of the rear end of the fixing pin is provided with an annular groove, and the inner wall of the annular groove is rotatably connected to a plate with reinforcing ribs.
[0009] Preferably, the rotating device includes a pair of thin shafts, and a pair of thin shafts are fixed to the rear end of each fixed pin. The pair of thin shafts are arranged in a circular array around the center of the fixed pin, and a synchronous connecting device is connected to the rear end of several pairs of thin shafts on each reinforcing rib.
[0010] Preferably, the synchronous connection device includes a synchronous connection plate and a rotating block. The rear ends of the thin shafts on the left and right sides are respectively connected to the left and right synchronous connection plates, and the rear ends of the pair of thin shafts at the top are connected to the rotating block. The front end face of the rotating block is slidably connected to the two synchronous connection plates.

[0012] The present invention proposes a quick-installation and disassembly blast-resistant wall for civil defense, which has the following advantages: the device installs several pairs of fixing pins on the reinforcing ribs. When installing the reinforcing ribs, several pairs of fixing pins can be inserted and installed at the same time. The fixing pins simultaneously fix and connect the unit wall, H-beams, and reinforcing ribs. This reduces the speed of installation and disassembly from two aspects: reducing the number of fixing pins inserted and inserting several pairs of fixing pins at one time. The installation and disassembly are faster, and the number of fixing pins used is reduced, thus lowering the cost. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-5 A quick-assembly and detachable air-raid shelter wall includes unit walls 1 and H-beams 6. Several rows of unit walls 1 are vertically stacked, with H-beams 6 between adjacent rows of unit walls 1. Both ends of the unit walls 1 are inserted into slots at the top and bottom of the H-beams 6. The back of the H-beams 6 is provided with several reinforcing ribs 7, and each unit wall 1 has a reinforcing rib 7 on its back. The front end of the flat plate of the reinforcing rib 7 is provided with several pairs of circular holes, and a fixing pin 2 is rotatably provided in each pair of circular holes. The front end of each pair of fixing pins 2 passes through the corresponding unit wall 1 and H-beams 6 and extends to the front of the H-beams 6. The front end of each H-beam 6 is provided with a front guard plate 3, and the front end of the front guard plate 3 is provided with slots 5 corresponding to several pairs of fixing pins 2. The top of the front end of the fixing pin 2 is provided with a snap-fit groove, and the front guard plate 3 is slidably inserted into the snap-fit groove. The rear end of the fixing pin 2 is provided with a rotating device. The interior of the unit wall 1 is provided with a steel plate 11 that is penetrated by the fixing pin 2.
[0021] The H-beams 6 that are adjacent vertically are staggered by the width of two unit walls 1 in the horizontal direction.
[0022] The front end face of the H-beam 6 has a mounting groove, and a spring piece 4 is fixed in the mounting groove. The spring piece 4 is located in the slot 5. The spring piece 4 prevents the front guard plate 3 from disengaging from the locking groove due to vibration.
[0023] The outer wall of the rear end of the fixing pin 2 is provided with an annular groove, and the inner wall of the annular groove is rotatably connected to the plate of the reinforcing rib 7.
[0024] The rotating device includes a pair of thin shafts 8. Each fixed pin 2 has a pair of thin shafts 8 fixed at its rear end. The pair of thin shafts 8 are arranged in a circular array around the center of the fixed pin 2. Several pairs of thin shafts 8 on each reinforcing rib 7 are connected to a synchronous connecting device at their rear ends.
[0025] The synchronous connection device includes a synchronous connection plate 9 and a rotating block 10. The rear ends of the thin shafts 8 located on the left and right sides are respectively connected to the two synchronous connection plates 9 through and rotatingly connected. The rear ends of the pair of thin shafts 8 located at the top are connected to the rotating block 10 through and rotatingly connected. The front end face of the rotating block 10 is slidably connected to the two synchronous connection plates 9.
[0026] The rear end face of the reinforcing rib 7 is provided with an inner magnet 12 and an outer magnet 13. The outer magnet 13 is fixed inside the fixing pin 2. The rear end face of the reinforcing rib 7 is provided with a through hole, and the inner magnet 12 corresponding to the outer magnet 13 is fixed inside the through hole. The inner magnet 12 and the outer magnet 13 keep the fixing pin 2 with the snap-fit groove facing upward.
[0027] Working principle: After the unit wall 1 and H-beam 6 are stacked alternately from bottom to top, several pairs of fixing pins 2 are inserted and passed through the unit wall 1 and H-beam 6 when the reinforcing rib 7 is lifted from the back. Then, the front guard plate 3 is placed close to the H-beam 6 from the front, so that the fixing pins 2 are inserted into the slots 5. The front guard plate 3 is lowered so that it falls into the snap-fit groove, fixing the front end of the fixing pin 2. Thus, the H-beam 6, the front guard plate 3, and the reinforcing rib 7 are fixed at the same time. During disassembly, the rotating block 10 is rotated so that the snap-fit groove of the fixing pin 2 faces downward, so that the front guard plate 3 can be removed and the reinforcing rib 7 can be removed from the back. At the same time, the connection between the unit wall 1 and the H-beam 6 can be contacted to complete the disassembly. The synchronous connecting plate 9 connects several pairs of fixing pins 2.
[0028] This device installs several pairs of fixing pins 2 on the reinforcing ribs 7. When installing the reinforcing ribs 7, several pairs of fixing pins 2 can be inserted and installed at the same time. The fixing pins 2 simultaneously fix and connect the unit wall 1, H-beam 6, and reinforcing ribs 7. This reduces the speed of installation and disassembly from two directions: reducing the number of fixing pins 2 inserted and inserting several pairs of fixing pins 2 at one time. The installation and disassembly are faster, and the number of fixing pins 2 used is reduced, thus reducing costs.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
