Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a guardrail for construction. Background Art

[0002] For construction safety and to serve as a warning and reminder, corresponding construction guardrails are placed on the construction site. Sometimes, it is even necessary to use guardrails to surround the construction site to prevent pedestrians or vehicles from entering the construction site by mistake. The structure of the traditional construction guardrail is relatively simple, including a guardrail body. The bottom of the guardrail body is fixed with supporting legs, which are usually welded to the guardrail body. The supporting legs and the guardrail body are perpendicular to each other. At the same time, for the stability of the guardrail body, the supporting legs will expand and extend outward.

[0003] Although the existing guardrail has good stability when in use, due to the design angle of the support legs, the support legs will affect each other when the guardrail is stacked, which is not conducive to the stacking of the guardrail. The guardrail requires a large space to be transported, which is inconvenient to transport. Therefore, a construction guardrail is proposed to address the above situation. Utility Model Content

[0004] The utility model aims to solve the defect in the prior art that the supporting legs may affect each other, which is not conducive to the stacking and placement of the guardrails, and proposes a construction guardrail.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A construction guardrail comprises a base, a frame is arranged on the top of the base, and a pair of support rods are arranged on the bottom of the base.

[0007] A pair of T-shaped grooves are provided at the bottom of the base, T-shaped blocks are slidably matched in the pair of T-shaped grooves, and a step rod is provided at the bottom of the T-shaped block, and the step rod passes through the T-shaped groove.

[0008] A convex block is arranged on the top of the support rod, a stepped hole is provided on the convex block, and the protruding end of the support rod is gap-matched with the stepped hole.

[0009] Two pairs of through holes connected to the T-shaped slots are provided on the top of the base, hand screws are inserted into the through holes, and the protruding ends of the hand screws are matched with the T-shaped blocks.

[0010] Preferably, the top of the T-shaped block has a screw hole, and the protruding end of the hand screw is threadedly matched with the screw hole.

[0011] Preferably, the outer surface of the step rod is provided with a friction surface.

[0012] Preferably, the frame body includes a concave rod, and a pair of vertical rods are arranged on the concave rod. The bottoms of the pair of vertical rods are fixedly connected to the top of the base.

[0013] Preferably, three rows of cross rods are arranged on the concave rod and the pair of vertical rods, and the number of cross rods in each row is two.

[0014] Preferably, the shape of the support rod is an inverted "凵" shape, and a rubber pad is arranged at the bottom of the support rod.

[0015] The utility model has the following beneficial effects:

[0016] 1. Through the structural design of the T-shaped groove, T-shaped block, stepped rod, convex block and stepped hole, when stacking and transporting the device, the support rod can be rotated by ° and then slid into the bottom of the base. At this time, the support rod is parallel to the base, and at the same time, the end of the support rod is flush with the end of the base, so that the whole device is a plane, and thus the device occupies less space when stacked, which is beneficial to the transportation of the guardrail.

[0017] 2. Through the structural design of the through hole, screw hole and hand-tightening screw, when the device is in use, it can play a role in fixing and limiting the T-shaped block, and thus can ensure the stability of the device during use. Description of the Drawings

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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.

[0025] Refer to Figure 1-5, A protective fence for construction, including a base 1. A frame 2 is arranged on the top of the base 1. The frame 2 includes a concave rod. A pair of vertical rods are arranged on the concave rod. The bottoms of the pair of vertical rods are fixedly connected to the top of the base 1. Three rows of cross rods are arranged on the concave rod and the pair of vertical rods, and the number of cross rods in each row is two.

[0026] A pair of support rods 3 are arranged at the bottom of the base 1. The shape of the support rod 3 is an inverted "U" shape, and a rubber pad is arranged at the bottom of the support rod 3.

[0027] A pair of T-shaped grooves 101 are opened at the bottom of the base 1. A T-shaped block 102 is slidably fitted in each of the pair of T-shaped grooves 101. A stepped rod 103 is arranged at the bottom of the T-shaped block 102. The stepped rod 103 passes through the T-shaped groove 101, and a friction surface is arranged on the outer surface of the stepped rod 103.

[0028] Specifically, the friction surface can be set with anti-slip lines, and the matching relationship between the stepped rod 103 and the stepped hole 401 is a tight and controllable rotational fit. The stepped rod 103 can rotate smoothly in the stepped hole 401, but this rotation requires the application of external force. In the static state, the cooperation between the stepped rod 103 and the stepped hole 401 is tight and there will be no self-rotation phenomenon. This is a well-known technical means in this technical field and will not be elaborated here.

[0029] A convex block 4 is arranged at the top of the support rod 3. A stepped hole 401 is provided on the convex block 4, and the穿出端 of the support rod 3 is in clearance fit with the stepped hole 401.

[0030] When stacking and transporting this device, the support rod 3 can be rotated 90°, and then the support rod 3 is slid into the bottom of the base 1, that is, from the state shown in Figure 1 to the state shown in Figure 2 At this time, the support rod 3 is parallel to the base 1, and at the same time, the end of the support rod 3 is flush with the end of the base 1, so that the whole device forms a plane, and thus the device occupies less space when stacked, which is beneficial to the transportation of the protective fence.

[0031] Two pairs of through holes 104 communicating with the T-shaped grooves 101 are opened at the top of the base 1. A hand-tightening screw 5 is inserted into the through hole 104, and the穿出端 of the hand-tightening screw 5 is matched with the T-shaped block 102.

[0032] Specifically, as shown in Figure 3 and Figure 5 shown, the top of the T-shaped block 102 has a threaded hole 1020, and the穿出端 of the hand-tightening screw 5 is in threaded fit with the threaded hole 1020.

[0033] When in use, as shown in Figure 1In the state shown, the hand screw 5 is then inserted into the through hole 104, so that the through hole 104 and the thread 1020 cooperate with each other, which plays a role in fixing and limiting the T-shaped block 102, thereby ensuring the stability of the device during use.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
