Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, in particular to a kind of open-close protective shed. BACKGROUND

[0002] In building construction, in addition to fixed processing area, some materials need to be processed on site, considering the vertical lifting convenience of building materials and the size limit of construction site, steel bars, formworks, water and electricity and other temporary processing areas are generally arranged in the coverage range of tower crane or near the building under construction. In order to protect the safety of personnel in the temporary processing area, a protective shed is usually set up in the temporary processing area.

[0003] In the prior art, the protective shed of building site is generally built by tools or steel pipe fastener, and the top structure of protective shed is fixed after building, which is not convenient for temporary disassembly and will cause material loss.

The patent can effectively prevent high-altitude falling objects from injuring people, and can ensure that steel bars, formworks, water and electricity and other materials under the protective shed are not wetted or damaged, but it cannot meet the construction demand of vertical lifting of materials in the protective shed. Vertical lifting in the protective shed of intensive processing area will cause great safety hazards to the surrounding area. Moreover, the top structure of protective shed is fixed after building, and the semi-finished products or finished products processed by workers in the protective shed are generally stacked around the processing machinery. When the materials in the protective shed are lifted, the top structure of protective shed will limit the falling of lifting hook, so the materials need to be moved from the protective shed to the outside before vertical lifting, which leads to time-consuming and laborious material movement, and the repeated movement of materials will also cause loss and increase construction cost.

DETAILED DESCRIPTION

[0030] The embodiments of the present application are described in detail below with reference to the accompanying drawings, but the present application can be implemented in various different ways as defined and covered by the following.

[0031] As Figure 1 , Figure 2 and Figure 3As shown, the open-close protective shed of the embodiment is used for temporary protection of the construction site, comprising a supporting mechanism 100, protective roofs 200 and a traction mechanism 300. The supporting mechanism 100 is used for positioning and installing on the ground of the construction site to support the protective roofs 200. Two protective roofs 200 are symmetrically arranged on both sides of the supporting mechanism 100. The ends of the two protective roofs 200 close to each other are rotatably connected to the supporting mechanism 100. Specifically, the two protective roofs 200 are used to rotate open-close relative to the supporting mechanism 100 in the direction of mutual opening or mutual folding, so that the two protective roofs 200 can perform open-close action with the end close to each other as the rotating fulcrum. When the two protective roofs 200 are laid flat on the supporting mechanism 100, the space below can be effectively protected to prevent high-altitude falling objects and ensure safety. By rotating, the two protective roofs 200 can be relatively close to each other to make the two protective roofs 200 fold, so that the space below the protective roof 200 is in an open state, facilitating the vertical lifting of the hook. The traction mechanism 300 is installed on the supporting mechanism 100 and connected with the protective roofs 200. The two protective roofs 200 can be brought close to each other or away from each other by traction, realizing automatic control of the open-close action of the protective roofs 200, which is simple, easy to operate and convenient, greatly improving work efficiency. Preferably, the two protective roofs 200 can be vertically folded on the top of the supporting mechanism 100. Thus, by controlling the expansion and folding of the two protective roofs 200 through the traction mechanism 300, the protective working condition and the lifting working condition can be quickly switched according to actual needs, which not only can timely respond to sudden weather conditions or protection needs of the construction site, effectively prevent high-altitude falling objects and improve the safety of construction, but also can simultaneously meet the construction needs of vertical lifting of materials, avoid the obstruction of the protective roof 200 to the falling hook, and do not need to move the materials to the outside of the protective shed for vertical lifting, saving time and effort, saving construction cost, and reducing the safety hazards to the personnel and facilities around the protective shed during lifting. Preferably, the protective roof 200 can be folded to the top of the supporting mechanism 100, reducing the occupied space and facilitating transportation and storage. Preferably, the protective roof 200 adopts modular design, has high standardization, can be quickly installed on site, is easy to remove, can be used repeatedly, has high practicality and on-site adaptability.

[0032] In use, the foundation of the open-close protective shed is positioned and laid out according to the construction site protective shed layout, the supporting mechanism 100 is positioned and installed at the laid-out position, then the verticality is adjusted, the protective roof 200 is hoisted to the supporting mechanism 100 by using vertical lifting mechanical equipment such as a tower crane or a crane, and then the traction mechanism 300 is installed for overall debugging to ensure that the traction mechanism 300 can stably control the relative opening and closing of the two protective roofs, so that the open-close protective shed can smoothly switch between the protective working condition and the lifting working condition.

[0033] As shown,Figure 1 , Figure 3 and Figure 4 As shown, the support mechanism 100 includes a positioning element for fixing to the construction site and a support element for horizontally supporting the protective canopy 200 in its open state. Specifically, the positioning element includes a plurality of columns 101 arranged at intervals along the same straight line, and the support element includes a horizontal bracket 102. The horizontal bracket 102 is installed on the plurality of columns 101 and symmetrically arranged along the columns 101 to provide stable support for the protective canopy 200 and ensure the stability of the protective canopy 200 during opening and closing. The upper end of the column 101 protrudes above the horizontal bracket 102 to facilitate connection of the protective canopy 200 and installation of the traction mechanism 300.

[0034] like Figure 1 and Figure 3 As shown, the horizontal support 102 includes several horizontal bars 1021 arranged in parallel, a vertical bar 1022 arranged in a direction perpendicular to the horizontal bars 1021 and connecting the several horizontal bars 1021 into a whole, and a diagonal brace 1023 inclined below the horizontal bars 1021. The first end of the horizontal bar 1021 is fixed to the column 101, the second end of the horizontal bar 1021 extends outward in the horizontal direction and is connected to the first end of the diagonal brace 1023, and the second end of the diagonal brace 1023 is inclined downward in the direction toward the column 101 and is connected to the column 101. Thus, the horizontal bars 1021 and vertical bars 1022 can be connected to form a stable grid structure to provide horizontal support for the protective canopy 200 when it is in the open state. The diagonal brace 1023 is located at the corner between the horizontal bar 1021 and the column 101, forming a stable triangular support structure with the horizontal bar 1021 and the column 101. This structure can distribute the force on the horizontal bar 1021, enhance structural stability, improve wind resistance, and increase the support force on the protective canopy 200. Preferably, the length of the horizontal bar 1021 is not greater than the width of the protective canopy 200, so as to ensure that the horizontal support 102 will not obstruct the hook after the two protective canopies 200 are closed, ensuring smooth vertical hoisting. Preferably, the horizontal bar 1021, vertical bar 1022, column 101, and diagonal brace 1023 are all connected by bolts, which facilitates disassembly and transportation for reuse and improves utilization.

Preferably, the output end of the winch 301 is arranged upward near the column 101, so that the traction rope 302 can be close to the column 101 upward. Therefore, one winch 301 can control the rotation of one protective canopy 200 through the corresponding traction rope 302, and simultaneously opening two winches 301 can control the relative opening and closing of two protective canopies 200, or a winch 301 can be opened alone to control one protective canopy 200 to be folded upward or laid flat downward to adapt to the on-site construction requirements and improve the flexibility of the device. Preferably, a limiting groove is arranged on the column 101 along the height direction, and the traction rope 302 is arranged in the limiting groove to limit and guide the traction rope 302 on the column 101, prevent the traction rope 302 from shaking on the column 101, and guide the traction direction to ensure smooth traction of the protective canopy 200 and improve safety. Preferably, a radial ring baffle is arranged on the pulley 303 to separate the two traction ropes 302, preventing the traction ropes 302 from crossing and winding on the pulley 303, and improving the traction efficiency of the protective canopy 200.
