Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a novel reusable steel pipe scaffolding connecting piece for wall attachment. Background Technique

[0002] A scaffolding is a working platform erected to ensure the smooth progress of each construction process. It can be divided into wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding according to different materials. Steel pipe scaffolding is relatively common in life. The steel pipe scaffolding is tied to the building wall through connecting pieces for wall attachment, so that the scaffolding remains stable. The current connecting pieces for wall attachment are relatively simple, mainly composed of steel pipes. Steel pipes are pre-embedded in the building structure, and then the form of steel pipes plus fasteners is used to tie to the scaffolding.

[0003] When the existing steel pipe scaffolding connecting piece for wall attachment is in use, the method of pre-embedding steel pipes into the wall in advance is adopted to tie the scaffolding, which results in relatively large loss of steel pipes and waste of materials. At the same time, when removing the steel pipes embedded in the wall, it is necessary to demolish the wall, and the workload of repairing the wall after demolition is large. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel reusable steel pipe scaffolding connecting piece for wall attachment to solve the problems of relatively large loss of steel pipes, waste of materials, the necessity of demolishing the wall when removing the steel pipes embedded in the wall, and the large workload of repairing the wall after demolition as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A novel reusable steel pipe scaffolding connecting piece for wall attachment includes nuts pre-embedded in the wall. The inner cavity of the nut is threadedly connected with high-strength bolts. One end of the high-strength bolt extends to the outside of the wall. One end of the bolt located outside the wall is fixedly connected with a blocking plate to prevent the fastener from falling off. The surface of the nut is provided with a reinforcing member to increase the contact area with the wall and thus increase the stress level of the nut. One side of the nut is provided with a protective component to prevent concrete from flowing into the inner cavity of the nut when pouring concrete.

[0007] Preferably, the reinforcing member includes a limiting plate fixedly sleeved on the outer circular surface of the nut, and a plurality of groups of fixing holes are arranged on the surface of the limiting plate in an annular array.

[0008] Preferably, a plurality of groups of reinforcing plates are fixedly connected to the surface of the nut, and one side of the reinforcing plate is welded to one side surface of the limiting plate.

[0009] Preferably, the protective component includes a protective tube connected to one side of the nut and sleeved on the surface of the high-strength bolt. One end of the protective tube is fixedly connected with a hollow threaded tube, and the hollow threaded tube is threadedly connected to the inner cavity of the nut.

[0010] Preferably, one end surface of the protective tube is fixedly connected with a connecting rope, and the other end of the connecting rope is fixedly connected with a cap. An external thread is provided at one end of the protective tube, and the cap is threadedly connected to the protective tube through the external thread.

[0011] Preferably, a nut is threadedly connected to the surface of the high-strength bolt.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the arrangement of the nut and the high-strength bolt in the present utility model, when it is necessary to disassemble the steel pipe scaffolding, only the fastener needs to be loosened, the fastener is removed from the surface of the high-strength bolt, and at the same time, the high-strength bolt is disassembled and separated from the nut, so as to complete the disassembly of the high-strength bolt. The disassembled high-strength bolt can be reused, effectively saving materials, and at the same time facilitating subsequent workers to repair the wall, making the workload of repairing the wall after demolition smaller.

[0014] 2. Through the arrangement of the protective tube and the hollow threaded tube in the present utility model, during the process of pouring concrete, the combination of the protective tube and the hollow threaded tube can effectively prevent concrete from entering the inner cavity of the nut, thus facilitating the subsequent installation of the high-strength bolt. At the same time, the hollow threaded tube is threadedly connected to the nut, ensuring the tight combination of the protective component and the nut, and also facilitating installation and disassembly. When the high-strength bolt is screwed into the nut, the high-strength bolt crushes the hollow threaded tube, and the debris of the hollow threaded tube is squeezed between the high-strength bolt and the nut, which can increase the friction between the high-strength bolt and the nut, effectively preventing the relative rotation between the high-strength bolt and the nut and preventing the nut from loosening.

[0015] 3. Through the arrangement of the cap in the present utility model, the connecting rope connects the cap and the protective tube together, preventing the cap from being lost. At the same time, the cap can be connected to the protective tube through the external thread, further enhancing the protection of the inner cavity of the protective tube and preventing foreign objects from entering the protective tube.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , this embodiment provides a reusable new type of steel pipe scaffold tie member, including a nut 101 pre-embedded inside the wall 100. The inner cavity of the nut 101 is threadedly connected with a high-strength bolt 104. One end of the high-strength bolt 104 extends to the outside of the wall 100. A blocking disc 106 for preventing the fastener from falling off is fixedly connected to one end of the bolt located outside the wall 100. A reinforcing member for increasing the contact area with the wall 100 and thus increasing the stress-bearing degree of the nut 101 is provided on the surface of the nut 101. A protective component for preventing concrete from flowing into the inner cavity of the nut 101 is provided on one side of the nut 101. Through the setting of the nut 101 and the high-strength bolt 104, when it is necessary to disassemble the steel pipe scaffold, only need to loosen the fastener, remove the fastener from the surface of the high-strength bolt 104, and at the same time disassemble the high-strength bolt 104 and separate it from the nut 101, so as to complete the disassembly of the high-strength bolt 104, and the disassembled high-strength bolt 104 can be reused, and at the same time it is convenient for the subsequent staff to repair the wall surface.

[0022] Furthermore, the reinforcing member includes a limit disc 103 fixedly sleeved on the outer circular surface of the nut 101. A plurality of groups of fixing holes 107 arranged in a circular array are opened on the surface of the limit disc 103. Through the setting of the limit disc 103, the limit disc 103 is sleeved on the outer circular surface of the nut 101, increasing the contact area between the nut 101 and the wall 100, making the stress distribution more uniform. The plurality of fixing holes 107 arranged in a circular array facilitate the construction workers to tie the limit disc 103 to the steel bars of the wall 100, and at the same time allow the concrete to flow in during the concrete pouring, thereby further enhancing the bonding force between the nut 101 and the wall 100 and improving the stability of the entire connection structure.

[0023] Preferably, a number of groups of reinforcing plates 102 are fixedly connected to the surface of the nut 101. One side of the reinforcing plate 102 is welded to one side surface of the limiting disc 103. Through the arrangement of the reinforcing plate 102, the nut 101 and the limiting disc 103 are welded together, increasing the connection strength between the two. And through the transmission of the reinforcing plate 102, the force received by the nut 101 can be more evenly dispersed to the limiting disc 103, further improving the bearing capacity of the entire reinforcing member.

[0024] Furthermore, the protection component includes a protection tube 200 connected to one side of the nut 101 and sleeved on the surface of the high-strength bolt 104. One end port of the protection tube 200 is fixedly connected with a hollow threaded tube 204. The hollow threaded tube 204 is made of rubber material and is threadedly connected to the inner cavity of the nut 101. Through the arrangement of the protection tube 200 and the hollow threaded tube 204, during the concrete pouring process, the combination of the protection tube 200 and the hollow threaded tube 204 can effectively prevent concrete from entering the inner cavity of the nut 101, thus facilitating the subsequent installation of the high-strength bolt 104. At the same time, the hollow threaded tube 204 is threadedly connected to the nut 101, ensuring the tight combination of the protection component and the nut 101, and also facilitating installation and disassembly. And when the high-strength bolt 104 is screwed into the nut 101, the high-strength bolt 104 crushes the hollow threaded tube 204, and the debris of the hollow threaded tube 204 is squeezed between the high-strength bolt 104 and the nut 101, which can increase the friction force between the high-strength bolt 104 and the nut 101, and can effectively prevent the relative rotation between the high-strength bolt 104 and the nut 101, preventing the nut 105 from loosening.

[0025] It is worth noting that one end surface of the protection tube 200 is fixedly connected with a connecting rope 202, and the other end of the connecting rope 202 is fixedly connected with a cap 203. An external thread 201 is provided at one end port of the protection tube 200, and the cap 203 is threadedly connected to the protection tube 200 through the external thread 201. Through the arrangement of the cap 203, the connecting rope 202 connects the cap 203 and the protection tube 200 together, avoiding the loss of the cap 203. At the same time, the cap 203 can be connected to the protection tube 200 through the external thread 201, further enhancing the protection of the inner cavity of the protection tube 200 and preventing foreign objects from entering the protection tube 200.

[0026] Further, a nut 105 is threadedly connected to the surface of the high-strength bolt 104. Through the arrangement of the nut 105, the nut 105 and the high-strength bolt 104 are used in cooperation to realize the clamping and fixing of different types of fasteners.

[0027] Working principle;

[0028] Before concrete pouring, first, according to the construction requirements, fix the nut 101 at the corresponding position of the building wall 100. Subsequently, take out the protective pipe 200, and thread the hollow threaded pipe 204 at one end of the protective pipe 200 into the inner cavity of the nut 101. At the same time, thread the cap 203 connected to one end of the connecting rope 202 onto the mouth of the protective pipe 200 to fix the protective pipe 200. Then pour concrete into the mold. When it is necessary to erect a scaffolding, remove the cap 203, then take out the high-strength bolt 104, pass it through the protective pipe 200 and thread it into the inner cavity of the nut 101. Subsequently, install the fastener on the surface of the high-strength bolt 104, and make one end of the fastener contact the surface of the blocking plate 106. At the same time, tighten the nut 105 on one side of the fastener to make the nut 105 close to the surface of the fastener to prevent the fastener from loosening. Then erect the steel pipe scaffolding upward. When it is necessary to disassemble, just loosen the fastener, remove the fastener from the surface of the high-strength bolt 104, and at the same time disassemble the high-strength bolt 104 and separate it from the nut 101, and draw out the high-strength bolt 104 from the wall 100, thus completing the disassembly of the high-strength bolt 104. And the disassembled high-strength bolt 104 can be reused, and at the same time it is convenient for the staff to repair the wall surface.

[0029] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
