Description

Technical Field

[0001] The utility model belongs to the technical field of building facilities, and in particular relates to a non-disassembly-free edge protection device for an opening. Background Art

[0002] In the process of building construction, establishing edge protection is an important measure to ensure the safety of construction workers. At present, there are roughly four types of edge protection in traditional buildings: steel pipe fastener edge protection, steel bar welding edge protection, simple wooden beam edge protection and tool-integrated edge protection. The first type of edge protection is a traditional practice widely used in construction. It can be disassembled by unscrewing the fastener with a wrench. The operation is relatively simple, but there are many rods and a large amount of labor. The second type of edge protection is disassembled by cutting the weld point. Compared with the fastener connection, it is slightly more complicated, and the steel bar may be deformed or reduced in size after disassembly, which is not suitable for reuse. The third type of edge protection is suitable for some temporary edge areas with relatively low protection requirements. It has great limitations, the wooden beams are easily damaged, the reuse rate is low, and the protection strength is limited. The fourth type of edge protection usually uses steel to make the frame, equipped with movable connection parts, such as bolt connection, pin connection, etc. The protection panel can be made of steel mesh or thin steel plate, etc., with a high turnover rate, but the cost is relatively high, and the installation and disassembly precision requirements are high. The four traditional edge protection methods have problems such as occupation of subsequent construction work surfaces, cumbersome installation and dismantling, waste of materials, and unstable safety performance.

[0003] The existing edge protection technologies cannot avoid the occupation of the subsequent construction work surface, which causes the problem of repeated disassembly of the edge protection during the construction process, greatly reducing the construction efficiency. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide a non-dismantling hole edge protection device, which is simple and convenient, does not affect the construction work surface, does not need to be dismantled after the construction is completed, and is convenient for subsequent maintenance and use.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The utility model discloses a non-disassembly hole edge protection device, comprising a plurality of guardrails and a concrete structure layer arranged around the hole, the guardrails are movably connected to the concrete structure layers on the left and right sides of the hole, the guardrails are arranged in a fastener, a support screw is arranged at the bottom of the fastener, a turnover screw is connected to the bottom of the support screw, a thread is arranged at one end of the turnover screw away from the support screw, a plurality of embedded inner support rods are arranged at intervals inside the concrete structure layers on the left and right sides of the hole, and the turnover screws are threadedly connected to the embedded inner support rods.

[0007] in:

[0008] The left and right sides of the guardrail are both provided with fasteners.

[0009] A plurality of pre-buried inner support rods in the concrete structure layer on the left and right sides of the opening are symmetrically arranged.

[0010] A fillet weld is provided at the connection between the fastener and the support screw.

[0011] The fastener is arranged on the top surface of the support screw rod, and the bottom surface of the support screw rod is connected to the top of one end of the epicyclic screw rod away from the thread.

[0012] A foundation is arranged at the bottom of the concrete structure layer, and a heat-insulating layer and a decorative layer are arranged outside the concrete structure layer.

[0013] An inner wall base layer and an inner wall covering layer are arranged inside the concrete structure layer.

[0014] The length of the embedded inner support rod is consistent with the thickness of the concrete structure layer.

[0015] A fastening steel plate is arranged on the outer side of the middle part of the embedded inner support rod, and the fastening steel plate is arranged vertically to the embedded inner support rod.

[0016] Both ends of the embedded inner support rod are provided with truncated cone-shaped fixed supports.

[0017] The beneficial effects of the utility model are:

[0018] The utility model disassembles the edge protection device, and each component has strong versatility and interchangeability, and can be flexibly combined and used in different construction scenarios. The components are connected by bolts, fasteners, etc., which makes installation convenient and subsequent maintenance more convenient. By installing the embedded inner support rod in the concrete structure, it is only necessary to connect the turnover screw through threads and then connect the guardrail through fasteners.

A support screw 3 is arranged at the bottom of the fastener 1. A circulating screw 5 is connected to the bottom of the support screw 3. A thread is arranged at one end of the circulating screw 5 away from the support screw 3. A plurality of embedded inner support rods 6 are arranged at intervals inside the concrete structure layers 9 on the left and right sides of the opening. The circulating screw 5 is threadedly connected to the embedded inner support rods 6.

[0026] Fasteners 1 are provided on both sides of the guardrail 4 .

[0027] The plurality of embedded inner support rods 6 in the concrete structure layer 9 on the left and right sides of the hole are symmetrically arranged. During construction, the embedded inner support rods 6 are symmetrically arranged on the concrete structure layer 9 on the left and right sides of the hole as required to achieve multi-level protection and reduce the occurrence of safety accidents.

[0028] A fillet weld 2 is provided at the connection between the fastener 1 and the support screw 3 .

[0029] The fastener 1 is arranged on the top surface of the support screw 3, and the bottom surface of the support screw 3 is connected to the top of one end of the epicyclic screw 5 away from the thread.

[0030] A foundation 12 is arranged at the bottom of the concrete structure layer 9 , and a heat-insulating layer 10 and a decorative layer 11 are arranged outside the concrete structure layer 9 .
