Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a safety protection fixing device. Background Technology

[0002] With the rapid development of my country's economy, construction projects are becoming increasingly standardized, with a particular emphasis on on-site safety and civilized construction. When reserving door and window openings on the exterior walls of buildings, temporary protection measures are required to prevent falls. Currently, commonly used protective devices for door and window openings mainly include guardrails and safety ropes.

[0003] Existing guardrails can be fixed to the side walls of an opening by means of top bracing, such as the edge opening protection device disclosed in Chinese Utility Model Patent CN204983706U, or fixed to the ground or column surface of the opening by bolts, such as the edge opening guardrail disclosed in Chinese Utility Model CN221321861U. Existing safety ropes are mostly fixed to the structural columns on both sides of the opening by wrapping around them.

[0004] The top-support installation of guardrails is prone to detachment under significant impact, resulting in poor protective effectiveness. Bolted installations and rope-wrapped installations can easily damage the structural columns and ground around openings, requiring costly repairs after construction. Therefore, a safety protection fixing device is needed to address the problems of inadequate protection from top-support installations and the structural damage caused by bolted or rope-wrapped installations in existing technologies. Summary of the Invention

[0005] The purpose of this utility model is to provide a safety protection fixing device that can solve the problems of poor protection effect of the top support installation of guardrails in the prior art, and the easy damage to the finished structure caused by the bolting of guardrails and the entanglement of safety ropes.

[0006] This utility model is implemented as follows:

[0007] A safety protection fixing device includes a pre-embedded connecting component and a protective component; the pre-embedded connecting component includes a pre-embedded component and a connecting component, the pre-embedded component is pre-embedded in the structural columns on both sides of the edge opening, and the two ends of the pre-embedded component are respectively vertically supported on the inner wall of the formwork on both sides of the structural column; one end of the connecting component is movably connected to the protective component, and the other end of the connecting component is movably connected to the end of the pre-embedded component, so that the protective component is connected between the structural columns on both sides of the edge opening through a pair of pre-embedded connecting components.

[0008] The pre-embedded components include limiting inner support top formwork ribs and connecting sleeves. The two ends of the limiting inner support top formwork ribs are coaxially connected to one end of a pair of connecting sleeves, and the other ends of the pair of connecting sleeves are vertically supported on the inner walls of the formwork on both sides of the structural column, so that the other ends of the connecting sleeves are flush with the column surface of the structural column; the protective components are movably connected to the other ends of the connecting sleeves through the connecting components.

[0009] The connecting component includes a connecting rod, one end of which is movably inserted into the protective component, and the other end of which is movably connected to the other end of the connecting sleeve.

[0010] The inner wall of the connecting sleeve is formed with an internal thread, and the two ends of the limiting inner support top mold rib are formed with a first external thread segment that matches the internal thread, so that the end of the limiting inner support top mold rib is screwed into one end of the connecting sleeve; the other end of the connecting rod is formed with a second external thread segment that matches the internal thread, so that the other end of the connecting rod is screwed into the other end of the connecting sleeve.

[0011] One end of the connecting rod has a safety pull ring.

[0012] The protective component is a guardrail structure. The end of the horizontal bar of the guardrail structure has a socket. One end of the connecting rod is coaxially inserted into the horizontal bar of the guardrail structure through the socket, and the outer diameter of the safety pull ring is larger than the diameter of the socket.

[0013] The protective component is a safety rope, with the end of the safety rope tied to a safety pull ring.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] 1. This utility model features a pre-embedded connecting component, which embeds the pre-embedded component into the structural columns on both sides of the edge opening. The protective component is connected to the pre-embedded component through the connecting component, making assembly and disassembly convenient and quick. This ensures that the protective component is firmly and stably installed between the walls on both sides of the edge opening, enabling it to exert an effective protective effect. It also eliminates the need to reinforce the protective component by drilling bolts, avoiding damage to the structural column surface and the ground, as well as subsequent special repairs. At the same time, the pre-embedded component can be used for limiting the position during formwork installation, which helps to improve the forming quality of the structural column surface, reduce construction costs, and ensure construction quality.

[0016] 2. Because this utility model is equipped with a safety pull ring, which is located inside the crossbar of the guardrail structure, it can play a connecting and limiting role, ensuring a reliable connection between the crossbar of the guardrail structure and the connecting components without loosening. The safety pull ring can also be used to tie and fix the safety rope, providing a stable installation point for the safety rope, avoiding damage to the column surface of the structural column caused by the safety rope winding on the structural column, and improving the aesthetics and firmness of the installation.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please see the appendix Figure 1 and attached Figure 2 A safety protection fixing device includes a pre-embedded connecting component 1 and a protective component; the pre-embedded connecting component 1 includes a pre-embedded component and a connecting component, the pre-embedded component is pre-embedded in the structural columns 4 on both sides of the edge opening, and the two ends of the pre-embedded component are respectively vertically supported on the inner wall of the template on both sides of the structural column 4; one end of the connecting component is movably connected to the protective component, and the other end of the connecting component is movably connected to the end of the pre-embedded component, so that the protective component is connected between the structural columns 4 on both sides of the edge opening through a pair of pre-embedded connecting components 1.

[0023] During construction, the embedded components are directly embedded within the structural columns 4 on both sides of the edge opening. The ends of the embedded components are positioned and reinforced by the formwork on both sides of the structural column 4 through top supports, preventing formwork displacement during construction and improving the forming quality of the column surface at the edge opening. Furthermore, after formwork removal, the embedded components can be used to connect with connecting components, serving as installation points for protective components. This not only ensures the reliability and safety of the protective components but also avoids drilling damage to the finished column surface or ground surface at the edge opening, and necessitates subsequent specialized repairs.

[0024] Please see the appendix Figure 2 The pre-embedded components include limiting inner support top formwork ribs 1-1 and connecting sleeves 1-2. The two ends of the limiting inner support top formwork ribs 1-1 are coaxially connected to one end of a pair of connecting sleeves 1-2, and the other ends of the pair of connecting sleeves 1-2 are vertically supported on the inner walls of the templates on both sides of the structural column 4, so that the other ends of the connecting sleeves 1-2 are flush with the column surface of the structural column 4; the protective components are movably connected to the other ends of the connecting sleeves 1-2 through the connecting components.

[0025] The lengths of the limiting inner support top formwork rib 1-1 and the connecting sleeve 1-2 can be adapted to actual usage requirements. The connecting sleeve 1-2 is pre-embedded in the structural column 4, facilitating the installation of protective components through the connecting components. There is no need to reinforce the installation of protective components by drilling and installing bolts; the pre-embedding method makes the column surface of the structural column 4 flat and aesthetically pleasing, thus avoiding damage to the column surface and subsequent repairs.

[0026] Please see the appendix Figure 3 The connecting component includes a connecting rod 1-3, one end of which is movably inserted into the protective component, and the other end of which is movably connected to the other end of the connecting sleeve 1-2.

[0027] The length of the connecting rod 1-3 can be adapted to the actual use requirements, so that it connects between the protective component and the connecting sleeve 1-2, which facilitates the adaptive installation of the standardized protective component at edge openings of different sizes.

[0028] Please see the appendix Figure 2 and attached Figure 3 The inner wall of the connecting sleeve 1-2 is formed with an internal thread, and the two ends of the limiting inner support top mold rib 1-1 are formed with a first external thread segment that matches the internal thread, so that the end of the limiting inner support top mold rib 1-1 is screwed into one end of the connecting sleeve 1-2; the other end of the connecting rod 1-3 is formed with a second external thread segment that matches the internal thread, so that the other end of the connecting rod 1-3 is screwed into the other end of the connecting sleeve 1-2.

[0029] Preferably, the limiting inner support top formwork rib 1-1 can be made of a 16mm diameter round steel bar with threads at both ends, and the connecting sleeve 1-2 can be made of a round steel pipe with threads on the inner wall. The connecting sleeve 1-2 can be screwed onto the limiting inner support top formwork rib 1-1 by threads. The length of the embedded component can be adjusted by rotating the threads, thereby adapting to structural columns 4 of different thicknesses, and has good versatility and adaptability.

[0030] Preferably, the connecting rod 1-3 can be made of round steel bar of the same specification as the limiting inner support top formwork rib 1-1 and threaded at one end for easy threaded connection with the connecting sleeve 1-2. The length of the connecting rod 1-3 can be adjusted by rotating the thread, so that the standardized protective component can be adapted to the size of the edge opening, making it easy to install the protective component between the two side walls of the edge opening, ensuring the installation of the protective component firmly and the protective effect.

[0031] Please see the appendix Figure 3 One end of the connecting rod 1-3 is provided with a safety pull ring 1-4, which is used for the installation and limiting of the protective component.

[0032] Please see the appendix Figure 3The protective component is a guardrail structure 2. The end of the crossbar of the guardrail structure 2 has a socket (not shown in the figure). One end of the connecting rod 1-3 is coaxially inserted into the crossbar of the guardrail structure 2 through the socket, and the outer diameter of the safety pull ring 1-4 is larger than the diameter of the socket.

[0033] The safety pull ring 1-4 prevents the connecting rod 1-3 from coming off the crossbar of the protective structure 2. During installation, one end of the connecting rod 1-3 abuts against the inner wall of the end of the crossbar of the protective structure 2 through the safety pull ring 1-4, and the other end of the connecting rod 1-3 is fixed in the connecting sleeve 1-2 by thread engagement, ensuring a reliable connection between the connecting component and the protective structure 2, so that the protective structure 2 can be fixedly installed at the edge opening.

[0034] Please see the appendix Figure 1 The protective component is a safety rope 3, and the end of the safety rope 3 is tied to the safety pull ring 1-4.

[0035] Safety rings 1-4 facilitate the binding and fixing of safety rope 3, preventing safety rope 3 from getting tangled on structural column 4, ensuring the connection reliability and protective effect of safety rope 3, and improving the aesthetics of the installation.

[0036] The limiting inner support top formwork reinforcement 1-1, connecting sleeve 1-2 and connecting rod 1-3 can all be processed from steel bar scraps commonly found on the construction site, which is easy to obtain and manufacture. It can make full use of waste materials on the construction site, reduce resource waste, and make construction environmentally friendly.

[0037] Please see the appendix Figure 1 To be continued Figure 3 The installation and use method of this utility model is as follows:

[0038] During the construction of the building structure, the limiting inner support top formwork reinforcement 1-1 is tied to the steel reinforcement structure of the structural columns 4 on both sides of the edge opening, and the two ends of the limiting inner support top formwork reinforcement 1-1 are connected to the sleeves 1-2 by threaded matching. According to the width of the structural column 4, the connecting sleeves 1-2 are rotated and adjusted so that the ends of the connecting sleeves 1-2 are attached to the inner walls of the formwork on both sides of the structural column 4; multiple sets of embedded components are pre-embedded at intervals along the height direction of the structural column 4 according to the protection height requirements. The embedded components can be used not only for the installation of protective components, but also for the positioning and fixing of the formwork.

[0039] The embedded height of the embedded components in the structural column 4 can be 0.2m, 1.2m, 2m, etc. The embedded height and quantity of the embedded components are determined according to the installation connection point of the protective components.

[0040] The structural column 4 is constructed using conventional methods. After the structural column 4 is completed, the ends of the connecting sleeves 1-2 are flush with the column surface of the structural column 4, i.e., the two side walls of the adjacent opening. This results in a good column surface formation and facilitates the installation of subsequent connecting components. Preferably, when pouring the concrete for the structural column 4, the ends of the connecting sleeves 1-2 can be wrapped with plastic film to prevent concrete from flowing into the connecting sleeves 1-2 and affecting the subsequent threaded connection and adjustment functions.

[0041] When using guardrail structure 2 as protection, the horizontal bars with connecting rods 1-3 at both ends are screwed into the connecting sleeves 1-2 at the corresponding height through threads. The upper and lower horizontal bars of guardrail structure 2 are fixed between the two side walls of the edge opening through four connecting rods 1-3 via pre-embedded components to form protection for the edge opening.

[0042] When using safety rope 3 as protection, screw connecting rod 1-3 into connecting sleeve 1-2, and tie safety rope 3 to safety pull ring 1-4 of connecting rod 1-3, thereby tensioning safety rope 3 between the two side walls of the opening at the edge. Multiple safety ropes 3 can be tensioned vertically at intervals. Alternatively, vertical auxiliary safety ropes can be connected between multiple safety ropes 3 to form protection for the opening at the edge.

[0043] The guardrail structure 2 and safety rope 3 can be used individually or in combination. They can be installed between the two side walls of the opening using the above-mentioned method through connecting components and pre-embedded components. Further details will not be provided here. This ensures the aesthetics and sturdiness of the installation of the protective components.

[0044] After use, the connecting and protective components can be disassembled and reused.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
