Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering construction, in particular to a protective frame tie-joint point component capable of stably supporting. Background Art

[0002] At present, the domestic construction market is developing rapidly. Not only are the heights of buildings getting higher and higher, but the underground development is also getting deeper and deeper. At this stage, the external scaffolding is erected with traditional steel pipe frames. The main safety measure is to tie with the pre-buried tie points of the main structure. The above method is only applicable to the above-ground building structure. The underground structure cannot reserve tie points due to waterproof requirements and retaining wall structures. The traditional reinforcement method is to set up a brace for the frame. The brace is not only limited by the site form, but also has an unsatisfactory effect on improving the overall stability of the frame, which poses a very large safety hazard to the construction workers on the frame.

[0003] For example, a tie point with publication number CN210177929U includes a first pipe, a second pipe, an external frame, a fastener, and a prefabricated mortar block, wherein the first pipe is buried inside the brickwork along a set direction, and the first pipe is filled with mortar. Furthermore, the first end of the second pipe passes through the mortar and is fixedly connected to the external frame arranged on the first side of the brickwork, and the second end of the second pipe is located on the second side of the brickwork, and the second end is detachably connected to the fastener. In this way, when the external frame is removed, the second pipe and the fastener can be removed, and then the second pipe can be directly removed from the first pipe. Since the first pipe is buried inside the brickwork, it is only necessary to set the prefabricated mortar block in the reserved hole formed by the first pipe and the inside of the brickwork to complete the secondary hole filling, thereby improving the efficiency of the secondary hole filling.

[0004] The above-mentioned anchor point is buried inside the brickwork through the first pipe, which can improve the efficiency of patching holes. However, when using the anchor point fixing bracket, the connection position between the component fixed at the anchor point inside the wall and the component of the fixing bracket has a low bearing capacity and the welding position is prone to breakage. Utility Model Content

[0005] The purpose of the utility model is to provide a protective frame anchor point assembly that can stably support, so as to solve the problems in the above-mentioned background technology that the connection position between the assembly at the anchor point fixed inside the wall and the assembly of the fixed bracket has low bearing capacity and the welding position is easy to break.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A protective frame anchor point assembly capable of stable support, comprising a steel bar body, a connecting block and a fastener, wherein a connecting block is welded to the front end of the steel bar body, one end of the fastener is rotatably mounted on the connecting block through a pin shaft, and a socket is provided at the other end of the fastener;

[0008] A threaded rod is installed on the side of the front end face of the connection block opposite to the socket, and the threaded rod passes through the socket and is fastened by a nut;

[0010] Furthermore, the fastener is an arc-shaped structure, and an arc-shaped groove is provided in the middle of a side of the fastener opposite to the connecting block.

[0011] Furthermore, a mounting thread is provided at the rear end of the steel bar body.

[0012] Furthermore, the adjustable support mechanism includes a movable block and a damping hydraulic support rod, the movable block is threadedly connected to the rotating screw, one end of the damping hydraulic support rod is hinged on the movable block, and the other end of the damping hydraulic rod is hinged on the steel bar body.

[0013] Furthermore, a disc is fixedly installed on the outer side of each rotating screw rod, limiting holes are evenly spaced on the disc, and a fixing hole is provided on the connecting block. The limiting hole is limited on the fixing hole of the connecting block by a pin rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The protective frame anchor point assembly that can stably support the present invention is provided with a connection block that can limit the position of the protective frame. The connection block is welded at the front end of the steel bar body, and a fastener is provided at the front end of the connection block. The fastener can fix the protective frame between the two arc grooves of the fastener and the connection block to fix the protective frame;

[0016] The utility model can greatly improve the stability of the frame after the frame is connected with the tie points pre-buried in the structural members without increasing the hidden danger of structural waterproofing, and also ensure the safety of the construction workers on the frame. Secondly, the basement adopts the form of a prop to fix the frame, which not only has poor stability, but also requires more steel pipes for propping. The amount of steel pipes used for propping can be greatly reduced to 1 / 4-1 / 5 of the amount used.

[0017] The utility model provides a threaded rod and a nut at the front end of the fastener, which can fix the fastener and improve the stability of the tie point fixing protection frame. The rear end of the steel bar body is provided with a mounting thread that can be installed on the external wall. The mounting thread is rotatably installed on the external wall and the internal template of the external wall surface through a threaded steel sleeve, which can be installed conveniently and stably.

[0018] 2. The protective frame tie-point assembly that can stably support the present invention is provided with an adjustable support assembly inside the connection block. By rotating the screw rod, the movable block can be adjusted to move left and right in the limit groove. A damping hydraulic support rod is provided at the rear end of the movable block. The output end of the damping hydraulic support rod is rotatably connected to the surface of the steel bar body, which can support the welding of the steel bar body and the connection block, thereby achieving the purpose of adjusting the support strength according to different forces and increasing the structural strength of the tie-point;

[0019] In addition, the adjustable support assembly can also adaptively adjust the inclination angle of the damping hydraulic support rod according to the erection position of the protective frame to achieve the purpose of avoiding obstacles. BRIEF DESCRIPTION OF THE DRAWINGS
