Description

Technical Field

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

[0002] During the construction of a building, accidents such as falling objects from high altitudes are prone to occur. Therefore, all personnel entering the construction site need to wear safety helmets, and in order to prevent outsiders from entering, guardrails need to be installed around the construction site.

[0003] In the Chinese utility model patent publication number CN220285471U, a guardrail is disclosed. The height of the guardrail can be adjusted during use through a designed adjustment mechanism, which is convenient for adjustment according to different on-site conditions. When construction workers enter the construction site, the height of the guardrail can be lowered, so that they can step over the guardrail to enter the construction site, eliminating the need to detour through the entrance and exit of the construction site to enter, thereby improving the applicability and use effect of the guardrail.

[0004] A search revealed that when the guardrail is raised or lowered to facilitate access, personnel must step over the retracted guardrail, which can easily cause tripping. Furthermore, the guardrail also creates a blocking effect, making it difficult for small carts and other construction tools to enter and exit quickly. Therefore, there is an urgent need to improve existing building construction guardrails and provide a building construction guardrail. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a building construction guardrail that can facilitate the safe passage of people and small tools, can effectively isolate from the outside, and prevent pedestrians from mistakenly entering the construction site and causing accidental safety accidents.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A building construction guardrail comprises two vertically arranged counterweight columns, the upper ends of the two counterweight columns being provided with vertical slots facing each other, a limit rod being fixed in the vertical slot of one of the counterweight columns, a control assembly being installed in the other counterweight column, and push-pull control assemblies being installed on the tops of the two counterweight columns;

[0008] Two first vertical rods are arranged between the two counterweight columns, and several second vertical rods are arranged at equal intervals between the first vertical rods and the counterweight columns. Several support components are arranged at intervals along the vertical direction between the counterweight columns and the second vertical rods, between adjacent second vertical rods, and between the second vertical rods and the first vertical rods.

[0009] Among them, the control component includes a movable rod, a first conical tooth, a second conical tooth and a handle. The movable rod bearing is installed inside the counterweight column. The lower end of the movable rod is fixed with a first conical tooth, the first conical tooth is engaged with the second conical tooth, and the second conical tooth is fixed with a handle. The handle is rotatably connected to the counterweight column.

[0010] The push-pull control assembly includes a crossbar, a connecting sleeve, a movable block, a first push rod and a second push rod. Connecting sleeves are fixed at both ends of the crossbar, one of which is a sliding sleeve arranged on the outside of the limit rod, and the other connecting sleeve is provided with an internal thread. The end of the movable rod located in the vertical slot is provided with an external thread structure, and the connecting sleeve with the internal thread is threadedly connected to the external thread structure of the movable rod.

[0011] The crossbar is slidably sleeved with two movable blocks, which are rotatably connected to the upper ends of the first and second push rods. The ends of the first and second push rods away from the movable blocks are hinged to the counterweight column and the second vertical rod respectively.

[0012] Wherein, the first push rod and the second push rod have the same length.

[0013] Wherein, the support assembly comprises a first support rod and a second support rod, the first support rod and the second support rod are of the same length and are rotatably connected;

[0014] Ends of the first support rod and the second support rod, which are located between the counterweight column and the second vertical rod and are away from each other, are rotatably connected to the counterweight column and the second vertical rod respectively;

[0015] Ends of the first support rod and the second support rod located between the two second vertical rods and away from each other are respectively rotatably connected to the two second vertical rods;

[0016] The ends of the first support rod and the second support rod that are located between the second vertical rod and the first vertical rod and are away from each other are rotatably connected to the second vertical rod and the first vertical rod respectively.

[0017] In summary, the present construction guardrail controls the rotation of the second conical tooth by the handle, and the first conical tooth can be used to control the rotation of the movable rod with a threaded structure on the top, so that the connecting sleeve can be controlled to drive the cross bar to rise stably and vertically along the limit bar, and the first push rod and the second push rod are used to pull the two first vertical rods to move toward the two counterweight columns respectively. When the two first vertical rods are apart and opened, the middle part of the guardrail can be fully opened, and a space for people or small construction tools to pass quickly is formed between the raised cross bar. Compared with the comparative documents, the present guardrail can be fully opened to form a temporary passage, which is convenient for the safe passage of people and small tools.

[0018] When the two first vertical poles are brought close to each other to close the guardrail, multiple sets of support components are used to facilitate the equidistant arrangement of multiple second vertical poles between the counterweight column and the first vertical pole. By setting up multiple sets of support components and second vertical poles, the construction site can be effectively isolated from the outside world, which can prevent pedestrians from mistakenly entering the construction site and causing unexpected safety accidents.
