Description

Technical Field

[0001] The utility model belongs to the technical field of building construction guardrails, and specifically relates to a building construction guardrail device with an adjustment structure. Background Art

[0002] Housing construction refers to the engineering entity formed by the construction of various types of housing buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Housing buildings refer to projects with roofs, beams, columns, walls, foundations and internal spaces that can meet people's needs for production, residence, study and public activities. Protective devices are needed to isolate the construction site during the construction of construction projects.

[0003] There are various kinds of protective devices used in existing construction projects, which are generally composed of brackets and protective nets. However, when the house is built to a certain height, the height of the guardrail needs to be increased. The common method is to install the guardrail again on the guardrail, which not only wastes installation time but is also unsafe.

[0004] There is also a method of adjusting the height by adding an extension rod to the bracket, but the protective net is fixed on the bracket. When the height of the bracket is adjusted, the height of the protective net cannot be adjusted, resulting in poor protection effect. At the same time, the protective net is fixed on the bracket and needs to be disassembled when stored, which is time-consuming and laborious.

[0005] To this end, we have proposed a protective device for building construction with an adjustable structure, which can not only adjust the height of the guardrail, but also the height of the protective net. It is also convenient for subsequent storage, thus saving time and effort. Utility Model Content

[0006] The purpose of this utility model is to provide a protective device for building construction with an adjustable structure, which can not only adjust the height of the guardrail, but also adjust the height of the protective net. It is also convenient for subsequent storage, thereby achieving the effect of saving time and effort.

[0011] Furthermore, a fixing seat is provided at the bottom of the hollow bracket.

[0012] Furthermore, a through slot is provided on the hollow bracket, and the sliding plate slides inside the through slot.

[0013] Furthermore, one end of the first rotating shaft passes through the hollow bracket and is installed with a rotating disk, an elastic component is provided on the rotating disk, an L-shaped fixing rod is provided on the elastic component, and an array of fixing holes is opened on the hollow bracket, and the L-shaped fixing rod is inserted into the fixing hole.

[0015] Furthermore, the fixing hole matches the L-shaped fixing rod.

[0016] The technical effects achieved by this utility model are:

[0017] 1. First, when people need to adjust the height, they pull the L-shaped fixing rod, which drives the movable rod to stretch the piston disk spring, so that the L-shaped fixing rod is pulled out from the fixing hole, and the rotating disk can be rotated. The rotating disk drives the first rotating shaft to rotate the first gear, so that the first gear drives the first meshing tooth to move the sliding plate upward, and the sliding plate drives the supporting block to move upward. The supporting block moves the soft steel wire mesh up through the fixing rod. At the same time, when the sliding plate moves upward, the second meshing tooth drives the second gear to rotate, and the second gear drives the second rotating shaft to drive the second rotating shaft to rotate the soft steel wire mesh cylinder, so that the soft steel wire mesh can be stretched, so that the soft steel wire mesh cylinder can be adjusted to different heights.

[0018] 2. When it is necessary to rewind, the rotating disk is rotated in the opposite direction, and the rotating disk drives the first rotating shaft to rotate the first gear, so that the first gear drives the first meshing tooth to move the sliding plate downward, and the sliding plate drives the supporting block to move downward, and the supporting block moves the soft steel wire mesh downward through the fixed rod. At the same time, when the sliding plate moves downward, the second meshing tooth drives the second gear to rotate, and the second gear drives the second rotating shaft to drive the second rotating shaft to rewind the soft steel wire mesh cylinder, thereby facilitating storage and achieving the effect of saving time and effort.

[0030] Furthermore, a fixing seat (not shown in the figure) is provided at the bottom of the hollow bracket 1, and the fixing seat is fixed to the outside by bolts, so that the whole device can be fixed, thereby preventing the phenomenon of tipping over during protection.

[0031] Furthermore, a through slot 13 is formed on the hollow bracket 1 , and the sliding plate 2 can slide inside the through slot 13 .

[0032] It should be noted that, in order to ensure that the sliding plate 2 can slide smoothly, a sliding groove can be opened inside the through groove 13, and the sliding plate 2 slides inside the sliding groove, thereby increasing stability.

[0033] Furthermore, the first gear 3 is rotatably arranged inside the hollow bracket 1 via the first rotating shaft, and the second gear 4 is rotatably arranged inside the hollow bracket 1 via the second rotating shaft.

[0037] Furthermore, the fixing hole 16 matches the L-shaped fixing rod 15 , so that the L-shaped fixing rod 15 can enter the fixing hole 16 and is not easy to shake.

[0038] It should be noted that: a connecting groove is provided on the hollow bracket 1, which is connected to the external bracket shell through the connecting groove, so as to form a quadrilateral guardrail during the building construction for protection.

[0039] The working principle of the utility model is as follows: first, when people need to adjust the height, by pulling the L-shaped fixing rod 15, the L-shaped fixing rod 15 drives the movable rod 20 to make the piston plate 19 stretch the spring 18, so that the L-shaped fixing rod 15 is pulled out from the fixing hole 16, and the rotating disk 14 can be rotated, and the rotating disk 14 drives the first rotating shaft to rotate the first gear 3, so that the first gear 3 drives the first meshing tooth 5 to move the sliding plate 2 upward, and the sliding plate 2 drives the supporting block 10 to move upward, and the supporting block 10 moves the soft steel wire mesh 12 upward through the fixing rod, and at the same time, when the sliding plate 2 moves upward, the second meshing tooth 6 drives the second gear 4 to rotate, and the second gear 4 drives the second rotating shaft to drive the second rotating shaft 8 to make the soft steel wire mesh 12 move upward.
