Description

Technical Field

[0001] The invention relates to the technical field of exterior wall insulation board installation, in particular to an anti-falling device for an exterior wall insulation structure of a building. Background Art

[0002] External wall insulation board is an insulation material used for the exterior wall of a building. It combines multiple functions such as insulation, waterproofing, and fireproofing, and is designed to improve the energy efficiency and living comfort of the building. According to different materials and manufacturing processes, external wall insulation boards can be divided into many types, such as polyurethane external wall insulation boards, extruded polystyrene (XPS) boards, polystyrene particle boards (EPS), rock wool boards, etc. In steel structure buildings, the application of external wall insulation boards can significantly improve the insulation performance of the building, reduce energy consumption, and help protect the steel structure from severe weather conditions. The fixing between the external wall insulation board and the steel structure material-stainless steel square tube is often done by bolts and nuts. Because the bolts are exposed to the external environment for a long time, the threads on their surface are easily damaged by rust, which in turn affects the stability of the connection between the external wall insulation board and the square tube, and the external wall insulation board is prone to fall off.

[0003] In order to avoid the above situation, the prior art CN117432088B provides a technical solution for fixing the exterior wall insulation board without bolts. Although this can avoid the problem of thread corrosion affecting stability, the exterior wall insulation board is fixed only by the anti-slip block and the bolt head extending from the inside of the stud. Since the diameter of the stud is small, the length of the anti-slip block that can be extended from the inside of the stud is also relatively short, which results in a smaller contact area between the anti-slip block and the inner wall of the square tube, resulting in concentrated force at the contact point between the anti-slip block and the inner wall of the square tube, which is prone to damage.

[0043] The preferred specific embodiments for implementing the present invention are described in detail below, and a clear and complete description is made in conjunction with the accompanying drawings.

[0044] Embodiment 1

[0045] See also Figure 1 The present invention provides an anti-falling device for the exterior wall insulation structure of a building, comprising an exterior wall insulation board 2 installed between two steel structure square tubes 1. For the convenience of installation, installation holes are provided on the front side of the steel structure square tube 1 and the four corners of the exterior wall insulation board 2. The exterior wall insulation board 2 is installed on the steel structure square tube 1 through four locking members 3. The locking members 3 pass through the installation holes to realize the installation of the exterior wall insulation board 2.

[0046] like Figure 2-7As shown, each locking member 3 in the present invention includes a bolt head 31, a first stud 32 is fixed on one side of the bolt head 31 close to the external wall insulation board 2, and a second stud 33 is provided on the end of the first stud 32 away from the bolt head 31. The head end cross-section of the second stud 33 in the present invention is circular, and the tail end cross-section of the second stud 33 is processed into a square, and the tail end of the second stud 33 contacts the inner wall of the steel structure square tube 1. A connecting column 35 is provided between the first stud 32 and the second stud 33, and a limiting disc 36 is fixed at one end of the connecting column 35. The limiting disc 36 is embedded in the first stud 32 and can rotate inside the first stud 32, so the connecting column 35 in the present invention can move with the first stud 32. When the external wall insulation board 2 is fixed to the steel structure square tube 1 by using the locking member 3, the first stud 32 penetrates the external wall insulation board 2, the connecting column 35 penetrates the steel structure square tube 1, and the second stud 33 passes through the mounting hole on the front side of the steel structure square tube 1 and moves to the inside of the steel structure square tube 1, as shown in FIG. Figure 3 and 4 As shown;

[0047] Because the first stud 32 and the second stud 33 in the present invention are designed as separate bodies, in order to be able to fix the first stud 32 and the second stud 33 together, as shown in FIG. Figure 6 and 7 As shown, a threaded rod 37 is fixed to one end of the first stud 32 near the second stud 33, and the outer wall of the threaded rod 37 is processed into a smooth section and a threaded section. The threaded section of the threaded rod 37 is threadedly connected to the inner wall of the second stud 33. The smooth section of the threaded rod 37 passes through the connecting column 35 and the limiting disc 36 and can rotate inside the connecting column 35 and the limiting disc 36. By rotating the bolt head 31 to drive the first stud 32 and the threaded rod 37 to rotate, the first stud 32 and the second stud 33 can be fixed together through the threaded rod 37. In addition, the thread processed at the outer end of the threaded rod 37 is hidden inside the second stud 33, which can also prevent corrosion, thereby helping to ensure the stability of the structure of the present invention.

[0048] To prevent the bolt head 31, the first stud 32 and the second stud 33 from falling off between the steel structure square tube 1 and the exterior wall insulation board 2, Figures 4 to 7 As shown, a plurality of (e.g., four) support anti-slipping members 34 are hingedly connected to the outer wall of one end of the second stud 33 close to the first stud 32. The support anti-slipping member 34 is parallel to the second stud 33 (e.g., Figure 7 ), the supporting anti-dropping piece 34 is supported and closely attached to the inner wall of the steel structure square tube 1 after the first stud 32 is inserted into the exterior wall insulation board 2, so as to prevent the bolt head 31 and the first stud 32 from falling off;

[0049] In this embodiment, the supporting anti-dropping member 34 includes a first abutting plate 341, a connecting plate 342 and a second abutting plate 343. Figure 5-7As shown, one end of the first abutment plate 341 is hinged to the connecting column 35, the connecting plate 342 is hinged between the other end of the first abutment plate 341 and one end of the second abutment plate 343, and the other end of the second abutment plate 343 is hinged to one end of the second stud 33;

[0050] When in use, the installation holes on the exterior wall insulation board 2 and the steel structure square tube 1 need to be aligned, and then Figure 7 The tail end of the second stud 33 shown is inserted into the mounting hole until the tail end face of the second stud 33 contacts the inside of the steel structure square tube 1, and then the first stud 32 is pushed along the mounting hole while maintaining parallelism, and the bolt head 31 and the first stud 32 are rotated while pushing the first stud 32, so as to use the first stud 32 to drive the threaded rod 37 to rotate, until the threaded section with external threads processed on the outer wall of the threaded rod 37 is completely screwed into the inner wall of the second stud 33, so as to complete the connection between the first stud 32 and the second stud 33. In the process of continuous pushing of the first stud 32, the connecting column 35 does not rotate. At the same time, due to the continuous reduction in the distance between the connecting column 35 and the second stud 33, the originally parallel first abutment plate 341, the connecting plate 342 and the second abutment plate 343 will begin to rotate, wherein the first abutment plate 341 rotates 90° clockwise around the hinge point, and the second abutment plate 343 rotates 90° counterclockwise around the hinge point, presenting as shown in the figure. Figure 5 and Figure 6 In the state shown, the end face of the connecting column 35 is completely fitted with the end face of the second stud 33, and the first abutment plate 341 and the second abutment plate 343 that are supported are also restricted between the second stud 33 and the connecting column 35. The first abutment plate 341 that is supported contacts the inner wall of the steel structure square tube 1, so that the front side of the steel structure square tube 1 and the external wall insulation board 2 can be clamped and restricted between the bolt head 31 and the first abutment plate 341 and the second abutment plate 343, and the first abutment plate 341 and the second abutment plate 343 that are supported cannot rotate backwards, so the effect of preventing the second stud 33 and the first stud 32 from falling off can be achieved, so as to reinforce the external wall insulation board 2 installed on the steel structure square tube 1.

[0051] In addition, in order to further reinforce the second stud 33, through holes are respectively opened on both sides of the steel structure square tube 1 during installation, such as Figure 1 and Figure 5-7As shown, two reinforcing members 4 are provided on the second stud 33 for reinforcing from both sides, each reinforcing member 4 includes a reinforcing rod 41 passing through a through hole, one end of the reinforcing rod 41 is fixedly connected to the second stud 33, and the other end of the reinforcing rod 41 is embedded in the side wall of the steel structure square tube 1. Specifically, one end of the reinforcing rod 41 is processed with a dovetail tenon 42 and an arc-shaped cover plate 43, and two first dovetail grooves 44 distributed in a mirror image are opened on the second stud 33, and the first dovetail groove 44 is adapted to the dovetail tenon 42. After the first abutment plate 341 and the second abutment plate 343 are propped up, the reinforcing rod 41 is inserted from the through holes on both sides of the steel structure square tube 1, so that the dovetail tenon 42 is inserted into the first dovetail groove 44, and the arc-shaped cover plate 43 at one end of the reinforcing rod 41 is located at the top or bottom of the tail end of the second stud 33, and the other end of the reinforcing rod 41 is processed into a rectangle and embedded in the side wall of the steel structure square tube 1. With the cooperation of the two reinforcing rods 41, the second stud 33 can be limited between the two reinforcing rods 41. Figure 5 As shown, the other end of the reinforcement rod 41 of the present invention is processed into a rectangle, and this end is embedded in the side wall of the steel structure square tube 1, which can also prevent the reinforcement rod 41 from falling out of the through hole. Under the action of the two reinforcement rods 41, the tail end of the second stud 33 is restricted, which can further ensure its stability, thereby further preventing it from falling off from the inside of the mounting hole.

[0052] Embodiment 2

[0053] As shown in Figures 8-12, what is different from the first embodiment is that the first abutment plate 341, the connecting plate 342 and the second abutment plate 343 of the anti-slipping member 34 are replaced by an abutment plate 344 in this embodiment, that is, the anti-slipping member 34 includes an abutment plate 344, the shape of the abutment plate 344 is the same as the first abutment plate 341 and the second abutment plate 343, one end of the abutment plate 344 is hinged to the end of the second stud 33 close to the first stud 32 through a rotating shaft, and a torsion spring 345 is provided at the outer end of the rotating shaft, one end of the torsion spring 345 is fixed to the second stud 33, and the other end of the torsion spring 345 is fixed to the abutment plate 344, and the torsion spring 345 is used to drive the abutment plate 344 to rotate around the rotating shaft. When the end face of the first stud 32 contacts the end face of the second stud 33, the abutment plate 344 rotates 90° clockwise around the rotating shaft;

[0054] A second dovetail groove 346 is provided at one end of the abutting plate 344 away from the torsion spring 345, a double-headed dovetail tenon 347 is inserted into the second stud 33, one end of the double-headed dovetail tenon 347 is embedded in the second dovetail groove 346 at one end of the abutting plate 344 so that the abutting plate 344 is parallel to the second stud 33, a rectangular groove for accommodating the abutting plate 344 is provided on the outer wall of the head end of the second stud 33, and the abutting plate 344 parallel to the second stud 33 is just located inside the rectangular groove;

[0055] Moreover, in this embodiment, a round rod 38 is fixed to one end of the first stud 32 close to the second stud 33, and a threaded rod 37 is fixed to one end of the round rod 38 away from the first stud 32. The outer wall of the threaded rod 37 is processed with threads. The cross-section of the tail end of the second stud 33 is circular, and the outer wall of the tail end of the second stud 33 is processed with external threads. Figure 8 As shown, in this embodiment, the second stud 33 is provided with a reinforcing member 4 for reinforcing from the tail end of the second stud 33, and the reinforcing member 4 includes an anti-dropping cap 45, and the inner wall of the anti-dropping cap 45 is processed with an internal thread; four pads 39 are fixed on the end surface of the first stud 32 close to the second stud 33;

[0056] During installation, the tail end of the second stud 33 needs to be threadedly connected to the inside of the anti-dropping cap 45, and a through hole needs to be opened on the rear wall of the steel structure square tube 1, and then the front end of the second stud 33 installed in the anti-dropping cap 45 is passed through the through hole, and then the rear end of the first stud 32 is passed through the installation holes on the exterior wall insulation board 2 and the steel structure square tube 1, and the round rod 38 is inserted into the second stud 33 while moving the first stud 32, and the first stud 32 is rotated until the threaded rod 37 is screwed into the second stud 33, completing the first stud 32 and The first stud 32 is connected with the second stud 33, and the first stud 32 can push the double-headed dovetail tenon 347 to move backward during the above movement so that it moves out of the second dovetail groove 346 at one end of the abutment plate 344. After leaving the locking of the double-headed dovetail tenon 347, the abutment plate 344 originally parallel to the second stud 33 can be rotated 90° clockwise under the elastic force of the torsion spring 345, and is clamped with the cushion block 39. The cushion block 39 is used to support the abutment plate 344, and the rotated abutment plate 344 contacts the inner wall of the steel structure square tube 1, as shown in FIG. Fig. 9 As shown, the steel structure square tube 1 and the external wall insulation board 2 can be clamped and restricted between the supported abutment plate 344 and the bolt head 31, so as to realize the installation and reinforcement of the external wall insulation board 2;

[0057] Similarly, the expanded abutment plate 344 can also prevent the first stud 32 and the second stud 33 from falling off from between the steel structure square tube 1 and the exterior wall insulation board 2. The length of the abutment plate 344 is not limited by the diameters of the first stud 32 and the second stud 33, which helps to avoid force concentration while ensuring anti-slip reinforcement, so as to enhance the reinforcement effect of the present invention on the exterior wall insulation board 2 during installation, and the anti-slip cap 45 can also reinforce the second stud 33 from the tail end to prevent it from falling off.
