Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a shielding component. Background Art

[0002] Before the main structure of a steel structure building is constructed, it is necessary to first fix and install several steel columns on the ground as the frame foundation. For high-rise steel structure buildings, after the steel columns are hoisted, it is necessary to weld another steel column at the upper end of each steel column to increase the height of the frame foundation. Before welding a new steel column, it is necessary to first set up an operating platform on the steel column fixed on the ground. The operating platform is fixed at a position 1.2m away from the upper end of the steel column. The specific fixing method is: the operating platform is placed on the reserved bracket end of the upper end of the steel column or the triangular support of the steel column, and the operator stands on the operating platform to perform welding operations. Among them, a hollow cavity is provided in the middle of the operating platform, and the steel column abuts against the side wall of the hollow cavity. For the convenience of construction, the hollow cavity of the commonly used operating platform is a square structure. However, when the steel column is a cylindrical structure, a large gap will result between the cylindrical structure and the operating platform, which is easy to cause safety problems such as the operator stepping on the air, sparks falling during welding, and welding tools falling.

[0003] In the prior art, wooden boards are laid above the gaps, and asbestos cloth is placed on the wooden boards for shielding. However, this shielding method requires a large amount of wooden boards, is inconvenient to obtain, and has low installation efficiency. Alternatively, a shielding structure can be made by on-site cutting according to the size of the gap. However, the shielding structure made on-site can only be applied to steel columns of one size and cannot be reused for steel columns of different sizes. Utility Model Content

[0004] In view of this, the utility model provides a shielding assembly to solve the problems of low installation efficiency of the structure for shielding the gap between the steel column and the operating platform and the inability to reuse steel columns of different sizes.

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.

[0034] According to an embodiment of the utility model, a shielding assembly is provided, which is suitable for being placed between a column and a supporting structure, and is used to close a gap between the column and the supporting structure. The shielding assembly includes: at least two shielding members 1, and the at least two shielding members 1 have a first state of fixed connection and a second state of separation. In the second state, the relative position between the at least two shielding members 1 is adjustable so that the shielding members 1 are adapted to the gap.

[0035] By placing a shielding component that matches the column and the supporting structure in the gap between them, the shielding component can close the gap, prevent the operator from stepping on empty space, and prevent sparks and welding tools from falling during welding operations, thereby preventing safety hazards to personnel under the supporting structure and ensuring construction safety; by fixing at least two shielding members 1 to close the gap, the demand for shielding members 1 is small, the materials are easy to obtain, and the installation efficiency is high; by making the relative positions of at least two shielding members 1 adjustable so that the shielding members 1 can adapt to gaps of different sizes, it is suitable for closing gaps between columns and supporting structures of various sizes, and can be mass-produced, saving production costs.

[0036] like Figure 1As shown, in this embodiment, there are four shielding members 1, and the four shielding members 1 together form a hollow cavity, and the shape and size of the hollow cavity are suitable for matching with the column. Specifically, the cross section of the column is circular, and the hollow cavity together formed by the four shielding members 1 is circular. Among them, the maximum size of the hollow cavity surrounded by the four shielding members 1 is 1.6m, and the minimum size is 1.2m. Correspondingly, the cross-sectional diameter range of the column is 1.2m-1.6m. By setting four shielding members 1, after adjusting the relative position of the column and the shielding member 1, the gap between the shielding member 1 and the column is smaller. As a convertible embodiment, the shielding member 1 can also be provided with two, three or five shielding members 1. The number of shielding members 1 is determined according to the actual situation, and there is no excessive restriction here. As a convertible embodiment, the cross section of the column can also be square, or pentagonal, or other shapes, and the shape of the hollow cavity together surrounded by the four shielding members 1 is also correspondingly square, or pentagonal, or other shapes. As a convertible implementation, the cross-sectional diameter of the column may also be 2 m or 2.5 m, and correspondingly, the size of the hollow cavity surrounded by the four shielding members 1 may also be set to 2 m or 2.5 m.

[0037] like Figure 2 As shown, the shielding member 1 in this embodiment includes: a first side wall 11; a second side wall 12, which is arranged at an angle with the first side wall 11, and the side of the second side wall 12 close to the column is connected to the side of the first side wall 11 close to the column through an arc edge 13. Among them, the second side wall 12 is perpendicular to the first side wall 11, and the arc edge 13 is concave. The shielding member 1 includes the first side wall 11 and the second side wall 12, which is convenient for placing the shielding member 1 on the supporting structure. By setting the arc edge 13, it is convenient to adapt to the shape of the column, thereby reducing the gap between the column and the shielding member 1. As a convertible embodiment, when the shielding member 1 is provided with three, the shielding member 1 is roughly trapezoidal, and the shape of the hollow cavity surrounded by the shielding member 1 is adapted to the shape of the column, and no excessive restrictions are made here. As a convertible embodiment, when the column is polygonal, the side of the second side wall 12 close to the column is connected to the side of the first side wall 11 close to the column through a straight edge.

[0038] like Figure 1 As shown, in this embodiment, the extension length of the first side wall 11 is the same as the extension length of the second side wall 12, and the first side walls 11 and the second side walls 12 of the four shielding members 1 form a square structure. By forming the four shielding members 1 into a square structure, it can be adapted to the shape of the support structure, and then placed exactly on the support structure, while preventing a gap between the support structure and the shielding members 1. As a convertible embodiment, the first side wall 11 and the second side wall 12 can also be set to an arc shape, and then the four shielding members 1 form a circular structure. The four shielding members 1 can also be formed into other shapes, as long as they can be placed on the support structure, and there are no excessive restrictions here.

[0039] like Figure 2 As shown, each shielding member 1 in this embodiment is provided with a plurality of through holes 14, and the relative position between two adjacent shielding members 1 is adjustable through different through holes 14. Specifically, the through hole 14 is provided at one end of the first side wall 11 close to the arc-shaped edge 13 and at one end of the second side wall 12 close to the arc-shaped edge 13. By adopting different through holes 14 to relatively adjust the relative position between the two shielding members 1, the structure is simple and the adjustment is convenient. As a convertible implementation method, it is also possible that a sliding groove is provided on the shielding member 1, and a slider is provided on the adjacent shielding member 1, and the adjustment of the shielding member 1 is achieved by sliding the slider in the sliding groove, or a plurality of through holes 14 are provided on the shielding member 1, and protrusions are provided on the adjacent shielding members 1, and the protrusions are snapped into different through holes 14 for adjustment.

[0040] like Figure 3 As shown, the through hole 14 in this embodiment is an oblong hole. Among them, the through hole 14 is formed by connecting two semicircular arc segments with a radius of 9 mm and two straight segments with an extension length of 9 mm. By setting the through hole 14 as an oblong hole, the relative position of adjacent shielding members 1 can be fine-tuned to further reduce the gap between the column and the shielding member 1; secondly, it can improve the accuracy of the connection of the shielding member 1 to avoid the inability to connect adjacent shielding members 1 due to production errors due to the mismatch of the through holes. As a convertible embodiment, it is also possible that the number of through holes 14 is set to be larger, so as to facilitate more accurate adjustment of the relative position between the shielding members 1.

[0041] The shielding assembly in this embodiment includes a fastener. In the first state, the fastener is inserted into the through hole 14 to achieve fixed connection between adjacent shielding members 1. The fastener is a latch. By using a fastener to fix the shielding member 1, the structure is simple, easy to disassemble, and can be easily used, thereby saving material costs. As a convertible embodiment, the fastener can also be other connection structures such as bolts or cable ties, and no excessive restrictions are made here.

[0042] The shielding assembly in this embodiment is directly placed on the supporting structure and is located above the gap. By placing the shielding assembly directly on the supporting structure, the supporting structure and the column will not be damaged, and it is easy to disassemble and install.

[0043] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
