Description

Technical Field

[0001] This utility model relates to the field of construction engineering guardrail technology, specifically a construction engineering guardrail that is easy to assemble. Background Technology

[0002] Construction guardrails are important safety facilities used in building construction. They are mainly installed in high-altitude work areas, near edges and openings, and in dangerous areas. Their purpose includes preventing people from falling, blocking falling materials, separating construction areas from non-construction areas, and ensuring site order and personnel safety. According to the usage scenario, common types include foundation pit guardrails, floor edge guardrails, and stair handrails. The materials are mostly steel, aluminum alloy, or high-strength plastic. During installation, the principle of protection before construction must be followed. In daily use, the structural stability should be checked regularly, and damaged parts should be repaired in a timely manner to ensure that it continues to play a safety protection role.

[0003] In order to save time and speed up the splicing of existing construction guardrails, a pin-to-hole splicing method is used. Although this splicing structure can quickly connect multiple guardrails, in actual use, as the construction cycle progresses, the gap between the pin and the hole will gradually increase. Especially in windy weather or unstable external environments, the guardrails may be at risk of partial tilting or even collapse due to insufficient tightness between the connections. In view of this, we provide a construction guardrail that is easy to splice. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a construction engineering protective railing that is easy to assemble.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction engineering guardrail that is easy to assemble, comprising a fence, with a left-side frame and a right-side frame fixedly connected to both sides of the outer wall of the fence, the left-side frame having multiple positioning holes on one side of its outer wall and an L-shaped deep groove on one side of its outer wall, the right-side frame having multiple positioning posts on one side of its outer wall and a guide member on one side of its interior, the right-side frame having a bidirectional screw rotatably connected to its interior center and a knob at the top end of the bidirectional screw, and the right-side frame having multiple threaded fittings slidably connected to its interior cavity, with fasteners fixedly connected to one side of the outer wall of each threaded fitting.

[0006] As described above, the positioning pin is inserted into the inner cavity of the positioning socket, and the outer wall of the positioning pin is in close contact with the inner wall of the positioning socket.

[0007] As described above, the outer wall of the guide member simultaneously penetrates one side of the interior of multiple threaded components, and the outer wall of the guide member is simultaneously slidably connected to one side of the interior of multiple threaded components.

[0008] As described above, the plurality of threaded fittings are located at both ends of the bidirectional screw, and the inner center of the threaded fitting is threadedly connected to one end of the bidirectional screw.

[0009] The aforementioned fasteners are all L-shaped metal structures, and the fasteners are symmetrically arranged on one side of the outer wall of the right-side station frame.

[0010] As described above, one end of the fastener extends into the interior of the L-shaped deep groove, and the outer wall of the fastener is in close contact with the inner wall of the L-shaped deep groove.

[0011] Compared with existing technologies, this easy-to-assemble construction engineering guardrail has the following advantages:

[0012] 1. In this utility model, after aligning the right side frame of one fence with the left side frame of another fence, the knob on the right side of the first fence is rotated, and multiple fasteners are driven by the thread to open outward from the middle and insert into the L-shaped deep groove on the left side of the other fence. Finally, the L-shaped deep groove fits tightly with the outer wall of the fastener, which prevents local tilting or collapse in windy weather or unstable external environment, and ensures the overall stability of the fence.

[0013] Second, the combination of the positioning post and the positioning hole of this utility model can initially position the lateral position of multiple fences when splicing them together, ensuring that adjacent fences are aligned and avoiding misalignment between fences when splicing them together. At the same time, the positioning post is initially fixed after being inserted into the positioning hole, which further improves the overall stability of the fence.

[0014] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-6 As shown, this utility model provides a technical solution: a construction engineering guardrail that is easy to assemble, including a fence 1. A left-side frame 2 and a right-side frame 3 are fixedly connected to both sides of the outer wall of the fence 1. A plurality of positioning holes 201 are opened on one side of the outer wall of the left-side frame 2, and an L-shaped deep groove 202 is opened on one side of the outer wall of the left-side frame 2. A plurality of positioning posts 301 are added to one side of the outer wall of the right-side frame 3, and a guide 302 is added to one side of the inside of the right-side frame 3. A bidirectional screw 303 is rotatably connected to the center of the inside of the right-side frame 3, and a knob 304 is added to the top end of the bidirectional screw 303. A plurality of threaded fittings 305 are slidably connected to the inner cavity of the right-side frame 3, and fasteners 306 are fixedly connected to one side of the outer wall of each of the plurality of threaded fittings 305.

[0026] After aligning the right side frame 3 of one fence 1 with the left side frame 2 of another fence 1, turn the knob 304 on the right side of the first fence 1. The threads will drive multiple fasteners 306 to open outward from the middle and insert them into the L-shaped deep groove 202 on the left side of the other fence 1. Finally, the L-shaped deep groove 202 and the outer wall of the fastener 306 will fit tightly together, completing the splicing operation between multiple fences 1.

[0027] like Figure 3 As shown, the positioning post 301 is inserted into the inner cavity of the positioning socket 201, and the outer wall of the positioning post 301 is in close contact with the inner wall of the positioning socket 201.

[0028] The positioning post 301 fits tightly against the inner wall of the positioning hole 201, ensuring that multiple fences 1 are flush with each other before splicing, and assisting the operator in aligning the fences 1 at the height.

[0029] like Figure 3 As shown, the outer wall of the guide 302 simultaneously penetrates one side of the interior of multiple threaded components 305, and the outer wall of the guide 302 is simultaneously slidably connected to one side of the interior of multiple threaded components 305.

[0030] The guide 302 passes through multiple threaded components 305, ensuring that the threaded components 305 can only move vertically in a straight line.

[0031] like Figure 3 and Figure 5 As shown, multiple threaded fittings 305 are located at both ends of the bidirectional screw 303, and the inner center of the threaded fitting 305 is threadedly connected to one end of the bidirectional screw 303.

[0032] By rotating the knob 304, the threaded assembly 305 can be driven to move synchronously in the opposite direction, and the fastener 306 completes the fixed constraint on the L-shaped deep groove 202.

[0033] like Figure 3-5 As shown, multiple fasteners 306 are all L-shaped metal structures, and multiple fasteners 306 are symmetrically arranged on one side of the outer wall of the right-side station frame 3.

[0034] Multiple threaded fittings 305 are symmetrically distributed at both ends of the bidirectional screw 303, and synchronous opening and closing are achieved through threaded transmission, so that the fastener 306 and the L-shaped deep groove 202 are mutually fixed and constrained.

[0035] like Figure 3 As shown, one end of the fastener 306 extends into the interior of the L-shaped deep groove 202, and the outer wall of the fastener 306 is tightly fitted with the inner wall of the L-shaped deep groove 202.

[0036] The fastener 306 extends into the inner cavity of the L-shaped deep groove 202 and fits tightly. The fastener 306 with the symmetrically arranged L-shaped structure plays an anti-falling role and prevents the fastener 306 from slipping due to vertical or horizontal tension.

[0037] It should be noted that the fasteners 306 are symmetrically arranged. After the fasteners 306 are inserted into the L-shaped deep groove 202, the knob 304 is turned and the two-way screw 303 drives the threaded fittings 305 at both ends to move outward synchronously along the guide 302 through the thread, so that the symmetrically distributed fasteners 306 open outward and form an interlock with the inner wall of the L-shaped deep groove 202 to complete the splicing operation between multiple fences 1.

[0038] Working principle: At the edge of the construction area of ​​the construction site, the worker first aligns the right side frame 3 of one fence 1 with the left side frame 2 of another fence 1, so that the positioning post 301 is inserted into the inner cavity of the positioning hole 201, ensuring that the adjacent fences 1 are of the same height and horizontally aligned. Then, the worker rotates the knob 304 at the top of the right side frame 3, which drives the internal bidirectional screw 303 to rotate. Driven by the thread on the outer wall of the bidirectional screw 303, the threaded assembly 305 moves outward synchronously along the guide 302, which drives the fastener 306 fixed on its outer wall to open outward. Finally, one end of the fastener 306 is tightly fitted with the inner wall of the L-shaped deep groove 202, forming a tight locking structure and completing the splicing of the adjacent fences 1.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
