Description

Technical Field

[0001] This utility model relates to the field of signage technology, specifically a construction sign. Background Technology

[0002] Construction site signs are indispensable directional tools on construction sites, used to indicate important information such as construction areas, safety warnings, and directions. Existing construction site signs mainly consist of two parts: a support frame and an indicator plate. The support frame, as a fixing and supporting structure, is usually made of sturdy metal materials, possessing good stability and durability. The indicator plate carries the specific directional information. During installation, workers first place the support frame on the ground, then place the indicator plate on the support frame. Using tools such as electric screwdrivers, screws are passed through the indicator plate and then screwed into the support frame until the screws are fully tightened, thus achieving a secure connection between the indicator plate and the support frame.

[0003] When signs need to be replaced for various reasons (such as damage, information updates, etc.), it is difficult for workers to ensure that the screws installed on the new signboard are aligned with the original threaded holes on the support frame during the reinstallation process. Due to the deviation in the screw installation position, a connection may occur between the two holes on the support frame. If the holes are connected during the screw tightening process, the threaded part of the screw may not be able to fully embed into the threaded hole of the support frame, thereby reducing the tightening effect of the screw. The screw may loosen, causing the signboard to fall off. Therefore, a construction signboard is proposed to address the above situation. Utility Model Content

[0004] The purpose of this utility model is to provide a construction sign. Through the structural design of pre-drilled screw holes, limiting plates and through holes, when the sign is replaced, it can ensure that the reinserted fixing bolts can be accurately aligned with the original pre-drilled screw holes on the fixing frame. This solves the problem that deviations in the screw installation position may cause a connection between two holes on the support frame, reducing the screw tightening effect.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a construction sign, including a fixed frame with pre-drilled screw holes and a limiting plate. The limiting plate has two assembly slots, and the outer wall of the limiting plate also has a through hole that communicates with the assembly slots. When the limiting plate is fixed to the fixed frame, the assembly slots cooperate with the fixed frame to form an assembly cavity. When an indicator plate is installed on the assembly cavity, a fixing bolt is fitted on the through hole. The fixing bolt passes through the indicator plate and engages with the pre-drilled screw holes.

[0007] Further, the fixing frame is a frame formed by welding four galvanized steel pipes end to end, and transverse square pipes are welded on the frame, and longitudinal square pipes for connecting the fixing frame are arranged on the transverse square pipes.

[0008] Further, a support frame is hinged on the fixing frame, and the shape of the support frame is "H".

[0009] Further, the shape of the limiting plate is "匚".

[0010] Further, when the indicating plate is fitted on the assembly cavity, the top and bottom of the indicating plate are respectively fitted with the assembly grooves.

[0011] The utility model has the following beneficial effects:

[0012] Through the structural design of reserved screw holes, limiting plates and through holes, when the indicating plate is replaced, it can ensure that the re-installed fixing bolts can accurately align with the original reserved screw holes on the fixing frame, avoiding the problem of increasing the drilling positions on the fixing frame caused by the deviation of the installation position of the fixing bolts, thereby effectively maintaining the rigidity of the fixing frame. At the same time, since the fixing bolts can be accurately and firmly screwed into the original reserved screw holes on the fixing frame during installation, the risk of fixing bolt loosening caused by the connection of two hole positions is avoided, and the stability and safety of the signboard are significantly improved.

[0013] Through the assembly cavity formed by the through hole and the fixing frame, when the indicating plate is installed, the assembly cavity can play a role in initially limiting the indicating plate, avoiding the deviation of the indicating plate during positioning, and improving the working efficiency of the staff when installing the fixing bolts.

[0014] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0020] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-4 , the present utility model provides a technical solution: a construction sign, including a fixed frame 1, a reserved screw hole 101 is provided on the fixed frame 1, a limiting plate 2 is provided on the fixed frame 1, the shape of the limiting plate 2 is "匚"-shaped, made of aluminum alloy material, and an assembly groove 201 is provided on the limiting plate 2, and there are two assembly grooves 201.

[0022] A through hole 202 is further provided on the outer wall of the limiting plate 2, the through hole 202 is communicated with the assembly groove 201. When the limiting plate 2 is fixed on the fixed frame 1, the assembly groove 201 and the fixed frame 1 cooperate to form an assembly cavity 203. When an indicator board 3 is installed on the assembly cavity 203, a fixing bolt 4 is fitted on the through hole 202, and the fixing bolt 4 passes through the indicator board 3 and is in threaded cooperation with the reserved screw hole 101.

[0023] Specifically, when the indicator board 3 is fitted on the assembly cavity 203, the top and bottom of the indicator board 3 are respectively in contact with the assembly groove 201.

[0024] Furthermore, the fixed frame 1 is a frame body formed by welding four galvanized steel pipes 102 end to end, a horizontal square pipe is welded on the frame body, and a vertical square pipe connecting the fixed frame 1 is provided on the horizontal square pipe.

[0025] A support frame 5 is hinged on the fixed frame 1, and the shape of the support frame 5 is "H"-shaped

[0026] Among them, the support frame 5 is also welded by galvanized hollow steel pipes of different lengths. After the support frame 5 is unfolded, it contacts the ground, which can ensure the stability of the fixed frame 1.

[0027] Among them, the setting of the horizontal square pipe and the vertical square pipe improves the stability of the fixed frame 1, and at the same time plays a supporting role for the installed indicator board 3. <​​​In this embodiment, when the indicator plate 3 needs to be replaced, the fixing bolt 4 is first unscrewed with an electric screwdriver, and the indicator plate 3 is taken out from one side of the fixing frame 1. Then, the new indicator plate 3 is inserted into the assembly cavity 203 from one side. Then, the operator can use an electric screwdriver again to screw the fixing bolt 4 into the through hole 202, so that the fixing bolt 4 passes through the new indicator plate 3 during the movement and enters the reserved screw hole 101 to complete the thread engagement with the reserved screw hole 101. This ensures that the reinstalled fixing bolt 4 can accurately align with the original reserved screw hole 101 on the fixing frame 1, avoiding the problem of increased drilling positions on the fixing frame 1 due to the installation position deviation of the fixing bolt 4, thereby effectively maintaining the rigidity of the fixing frame 1. At the same time, since the fixing bolt 4 can be accurately and firmly screwed into the original reserved screw hole 101 on the fixing frame 1 during installation, the risk of loosening of the fixing bolt 4 due to the connection of the two holes is avoided, which significantly improves the stability and safety of the sign.
