Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete crack-resistant wall technology, and in particular to an explosion-proof reinforced concrete crack-resistant wall. Background Technology

[0002] In today's society, explosion-proof reinforced concrete crack-resistant walls have become an indispensable part of various public places, urban infrastructure, and key units. In public places such as hospitals and office buildings, explosion-proof reinforced concrete crack-resistant walls can effectively isolate areas such as wards and offices, thereby protecting the safety of people and property and improving the structural strength of buildings. Explosion-proof reinforced concrete crack-resistant walls are a professional building material with strong fire resistance and explosion resistance. In building design and construction, explosion-proof reinforced concrete crack-resistant walls are usually used to reinforce the structure of buildings and improve their overall building safety. However, because explosion-proof structures are heavy, they increase the overall weight of the building, increasing the requirements for the bearing capacity of the building foundation. Moreover, explosion-proof walls are required to prevent damage to the main wall or reduce damage when subjected to impact or explosion. When cracks appear in the wall, the explosion-proof structure cannot prevent the cracks from spreading. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide an explosion-proof reinforced concrete crack-resistant wall, which solves problems such as the heavy weight of explosion-proof structures, high requirements for the foundation, and the inability to reduce the degree of cracking when the wall cracks.

[0004] According to this utility model, an explosion-proof reinforced concrete crack-resistant wall includes a reinforced concrete wall and an explosion-proof plate. A steel frame is erected within the reinforced concrete wall, and extended steel bars are welded to the steel frame in a matrix arrangement. One end of each extended steel bar protrudes from the front sidewall of the reinforced concrete wall. The explosion-proof plate is affixed to the front sidewall of the reinforced concrete wall in multiple horizontal rows, with adjacent rows of explosion-proof plates staggered. The four corner positions of the explosion-proof plate are fixed to the front sidewall of the reinforced concrete wall with expansion bolts. The explosion-proof plate is embedded within the extended steel bars, and the extended steel bars are welded to the outer wall of the explosion-proof plate. The explosion-proof plate includes a square frame, a honeycomb rubber layer, and a stone... The structure consists of a cotton mesh layer and a reinforced concrete sealing layer. The inner wall of the square frame has a concave square annular groove. A first metal mesh is welded to the opening on the back of the square frame. A honeycomb rubber layer is laid on the first metal mesh, with the four sides of the honeycomb rubber layer inserted into the concave square annular groove. An asbestos mesh layer is laid on the honeycomb rubber layer. A fine steel mesh is built on the asbestos mesh layer. Then, concrete is poured on the fine steel mesh to form a reinforced concrete sealing layer. A second metal mesh is welded to the opening on the front side of the square frame. The front side of the reinforced concrete wall is filled with concrete in the gap between the explosion-proof plates, so that the front side of the explosion-proof plates is flat.

[0005] In some embodiments of this utility model, the steel reinforcement frame includes two rows of vertical steel bars, two rows of horizontal steel bars, and connecting steel bars. The two rows of vertical steel bars and the two rows of horizontal steel bars are welded to each other in a mesh pattern on the front and rear sides. The two rows of vertical steel bars and the two rows of horizontal steel bars are connected by connecting steel bars at corresponding points at the intersection positions.

[0006] In some other embodiments of this utility model, two rows of extended steel bars are welded above and below the horizontal steel bar on the same horizontal plane. The interval between the two rows of extended steel bars on the horizontal steel bar on the same plane is the diameter width of the horizontal steel bar. The ends of the extended steel bars are hooked to the rear horizontal steel bar.

[0007] In some other embodiments of this utility model, the length of the extended reinforcing bar protruding from the reinforced concrete wall is 2 / 3 of the thickness of the explosion-proof plate.

[0008] In some other embodiments of this utility model, the explosion-proof plate is positioned between two horizontal rows of extended reinforcing bars at a distance greater than the width of the explosion-proof plate by 0.5-1.0 cm. After the explosion-proof plate is positioned between the two horizontal rows of extended reinforcing bars, a pry bar is used to strike the extended reinforcing bars against the explosion-proof plate, so that the extended reinforcing bars are attached to the explosion-proof plate, and then welding is performed.

[0009] In some other embodiments of this utility model, the explosion-proof thickness does not exceed 1 / 5 of the thickness of the reinforced concrete wall.

[0010] In this invention, the asbestos mesh layer is fire-resistant, and the honeycomb rubber layer can withstand a large explosive force, giving the explosion-proof plate a strong explosion-proof capability. In addition, the explosion-proof plate is installed on the outer wall of the wall, which plays an important role in protecting the wall. When the wall cracks, the square frame is a metal frame, and the cross arrangement is like building a metal mesh on the wall, adding another metal mesh, reducing wall cracking and improving the stability of the wall structure.

[0020] 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.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] Reference Figure 1-7 An explosion-proof reinforced concrete crack-resistant wall includes a reinforced concrete wall 1 and an explosion-proof plate 4. A steel frame 2 is erected inside the reinforced concrete wall 1, and extension steel bars 3 are welded to the steel frame 2 in a matrix arrangement. One end of each extension steel bar 3 protrudes from the front wall of the reinforced concrete wall 1. The explosion-proof plate 4 is attached to the front wall of the reinforced concrete wall 1 in multiple horizontal rows, with adjacent rows of explosion-proof plates 4 staggered. The four corner positions of the explosion-proof plate 4 are fixed to the front wall of the reinforced concrete wall 1 with expansion bolts 5. The explosion-proof plate 4 is embedded within the extension steel bars 3, and the extension steel bars 3 are welded to the outer wall of the explosion-proof plate 4. The explosion-proof plate 4 includes a square frame 41, a honeycomb rubber layer 43, an asbestos mesh layer 44, and a reinforced concrete seal. The sealing layer 45 consists of a square frame 41 with an inner concave square annular groove 411 on its inner wall. A first metal mesh 42 is welded to the opening on the back of the square frame 41. A honeycomb rubber layer 43 is laid on the first metal mesh 42 and its four sides are inserted into the concave square annular groove 411. An asbestos mesh layer 44 is laid on the honeycomb rubber layer 43. A fine steel mesh is built on the asbestos mesh layer 44. Concrete is then poured into the fine steel mesh to form a reinforced concrete sealing layer 45. A second metal mesh 46 is welded to the opening on the front side of the square frame 41. The front side of the reinforced concrete wall 1 is filled with concrete in the gap between the explosion-proof plates 4, so that the front side of the explosion-proof plates is flat.

[0023] First, build the steel frame 2, then tie or weld the extension steel bars 3. Next, build the outer frame of the reinforced concrete wall 1, pour concrete into it, wait for it to solidify, measure the positions of the holes for expansion bolts on the outside of the reinforced concrete wall 1, drill the holes, install the expansion bolts, install the explosion-proof plate 4 on the expansion bolts, and then fix it.

[0024] The explosion-proof panel 4 is pre-assembled, and the square frame 41 is a pre-welded steel frame. The specific steps are as described above.

[0025] The front side wall of the reinforced concrete wall 1 is filled with concrete in the gap between the explosion-proof plates 4, so that the front side of the explosion-proof plates is flat and waiting for solidification.

[0026] When a bomb or explosion occurs on the surface of the explosion-proof plate 4, the reinforced concrete sealing layer 45 plays a certain role in preventing the explosion. When the reinforced concrete sealing layer 45 falls off, the asbestos mesh layer 44 can play a good fireproof role. When an explosion occurs, the impact force is absorbed by the honeycomb rubber layer 43, which greatly reduces the impact force. At this time, the impact on the reinforced concrete wall 1 is greatly reduced.

[0027] The explosion-proof panels 4 are staggered, acting like protective panels, providing protection regardless of the direction in which the wall cracks. The square frame 41 will not elongate to prevent further cracking.

[0028] The steel reinforcement frame 2 includes two rows of vertical steel bars 21, two rows of horizontal steel bars 22, and connecting steel bars 23. The two rows of vertical steel bars 21 and the two rows of horizontal steel bars 22 are welded to each other in a mesh pattern on the front and rear sides. The two rows of vertical steel bars 21 and the two rows of horizontal steel bars 22 are connected by connecting steel bars 23 at corresponding points at the intersection. For some welded positions, steel bars can be bent or wrapped with steel wire.

[0029] Two rows of extension bars 3 are welded above and below the horizontal reinforcing bar 22 on the same horizontal plane. The distance between the two rows of extension bars 3 on the horizontal reinforcing bar 22 on the same plane is the diameter width of the horizontal reinforcing bar 22. The ends of the extension bars 3 are hooked to the rear horizontal reinforcing bar 22 with hooks 31. The extension bars 3 can further pull the explosion-proof plate 4 and can form an integral part with the reinforcing bar frame 2, improving stability.

[0030] The length of the extended reinforcing bar 3 protruding from the reinforced concrete wall 1 is 2 / 3 of the thickness of the explosion-proof plate 4. This ensures that the extended reinforcing bar 3 is within the interval, and can be covered by the subsequent filling concrete.

[0031] The explosion-proof plate 4 is positioned between the two horizontal rows of extended reinforcing bars 3 at a distance 0.5-1.0 cm greater than the width of the explosion-proof plate 4. After the explosion-proof plate 4 is positioned between the two horizontal rows of extended reinforcing bars 3, a pry bar is used to strike the extended reinforcing bars 3 against the explosion-proof plate 4, causing the extended reinforcing bars 3 to adhere to the explosion-proof plate 4 before welding. This method facilitates the insertion of the explosion-proof plate 4 and makes bending the extended reinforcing bars 3 convenient.

[0032] The thickness of the explosion-proof plate 4 shall not exceed 1 / 5 of the thickness of the reinforced concrete wall 1. The explosion-proof plate 4 shall not be too thick to prevent the outer wall of the reinforced concrete wall 1 from bearing too much stress and being prone to falling off.

[0033] 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.
