Description

Technical Field

[0001] This utility model relates to the field of steel grating technology, and more specifically, to an anti-slip building steel structure. Background Technology

[0002] Construction engineering refers to the physical engineering project formed through the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Steel grating structures are frequently used in construction. Steel grating is an open steel component made by orthogonally combining load-bearing flat steel bars and crossbars at certain intervals, and fixing them by welding or press-locking. The crossbars are generally made of twisted square steel, but round steel or flat steel can also be used, and the materials are divided into carbon steel and stainless steel. Steel grating is mainly used for steel structure platform panels, trench covers, steel stair treads, and building ceilings.

[0003] Current steel gratings are mainly composed of a steel frame, flat steel, and crossbars welded together. In order to improve the anti-slip properties of the top surface of the steel grating, the crossbar structure often uses twisted square steel (i.e., spiral bars) fixed to the flat steel to increase friction. However, with long-term use, the spiral grooves on the crossbars are easily worn flat and slipped due to long-term friction, resulting in a reduction in the overall anti-slip performance of the steel grating. Replacing the crossbar structure directly would increase labor costs.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can effectively address the technical problem of the reduced anti-slip performance of steel gratings over long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip building steel structure, comprising a steel frame, wherein a flat steel one and a flat steel two are fixedly connected inside the steel frame, an anti-slip sleeve is fixedly connected to the flat steel one, an anti-slip crossbar is rotatably connected to the anti-slip sleeve, the anti-slip crossbar passes sequentially through the flat steel two and the steel frame, and a locking component is provided at one end of the anti-slip crossbar, the locking component being detachably connected to the steel frame.

[0007] In a preferred embodiment, there are multiple flat steel bars one and two, and both flat steel bars one and two are inclinedly arranged inside the steel frame.

[0008] In a preferred embodiment, the flat steel bar is provided with a storage groove that matches the size of the anti-slip sleeve.

[0009] In a preferred embodiment, an anti-slip strip is fixedly connected to the outer surface of the anti-slip sleeve.

[0010] In a preferred embodiment, the anti-slip crossbar is composed of multiple grooved segments and smooth segments, and the anti-slip crossbar is rotatably connected to the anti-slip sleeve through the smooth segments.

[0011] In a preferred embodiment, the flat steel 2 is provided with a second storage groove for the twisted groove section of the anti-slip crossbar to pass through, and the steel frame is provided with a third storage groove for the twisted groove section of the anti-slip crossbar to pass through.

[0012] In a preferred embodiment, the locking assembly includes a hinge seat fixedly connected to one end of the anti-slip crossbar, a fixing plate hinged to the hinge seat, a fastening bolt threaded onto the fixing plate, and three threaded grooves for threaded connection of the fastening bolts on the side of the steel frame.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model, by setting anti-slip sleeves and anti-slip crossbars on flat steel one and flat steel two, and by welding the anti-slip sleeves to flat steel one, improves the connection strength of the combined anti-slip sleeves and anti-slip crossbars. The rotatable anti-slip crossbars are used to adjust the angle of the spiral groove section, and the locking assembly is used to lock the angle adjustment of the anti-slip crossbars. This improves the utilization rate of the structural surface of the spiral groove section used for anti-slip treatment, increases the anti-slip durability of the anti-slip crossbars, and thus reduces the labor cost of steel grating.

[0015] 2. In this utility model, by setting the angle of the first flat steel and the second flat steel to change the fixed angle of the traditional flat steel, the angled flat steel or the second flat steel can increase the contact resistance and further improve the anti-slip performance of the steel grating.

Detailed Implementation

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See also Figures 1-6 This utility model provides a non-slip building steel structure, including a steel frame 1. Flat steel 1 2 and flat steel 2 3 are fixedly connected inside the steel frame 1. Flat steel 1 2 and flat steel 2 3 are welded to the steel frame 1. Flat steel 1 2 and flat steel 2 3 are used to fill the support surface inside the steel frame 1.

[0026] In this embodiment, there are multiple flat steel bars 1-2 and flat steel bars 2-3, and both flat steel bars 1-2 and flat steel bars 2-3 are inclinedly arranged on the inner side of the steel frame 1.

[0027] The inclined flat steel bar 12 or flat steel bar 23 can increase the resistance when people walk on it, preventing slippage when the foot exerts force, thus increasing the anti-slip performance of the steel grating.

[0028] In this embodiment: an anti-slip sleeve 4 is fixedly connected to the flat steel 2, and an anti-slip crossbar 5 is rotatably connected to the anti-slip sleeve 4.

[0029] The anti-slip sleeve 4 can be connected and cooperated with the anti-slip crossbar 5 through the bearing. The anti-slip sleeve 4 can be welded and fixed on the flat steel 2, so as to stabilize the position of the anti-slip crossbar 5 on the anti-slip sleeve 4 and give full play to the anti-slip characteristics of the anti-slip crossbar 5.

[0030] In this embodiment, a storage groove 21 adapted to the size of the anti-slip sleeve 4 is provided on the flat steel 2.

[0031] The location of the storage slot 21 can be used to embed and install the anti-slip sleeve 4 to ensure the fit of the anti-slip sleeve 4 on the flat steel 2. The anti-slip sleeve 4 can be fixed to the flat steel 2 by welding.

[0032] In this embodiment, an anti-slip strip 41 is fixedly connected to the outer surface of the anti-slip sleeve 4.

[0033] Multiple anti-slip strips 41 are provided, and multiple anti-slip sleeves 41 are equidistantly distributed on the outer surface of the anti-slip sleeve 4. The anti-slip strips 41 can increase the friction of the surface of the anti-slip sleeve 4. When the anti-slip sleeve 4 is fixedly connected to the flat steel 2 and is in contact with by people walking, this can increase the anti-slip performance.

[0034] In this embodiment: the anti-slip crossbar 5 is composed of multiple twisted groove sections 6 and smooth sections 7, and the anti-slip crossbar 5 is rotatably connected to the anti-slip sleeve 4 through the smooth sections 7.

[0035] The twisted groove section 6 of the anti-slip crossbar 5 can be used to increase the friction of the foot contact. With the groove shape of the twisted groove section 6, the anti-slip crossbar 5 can have good anti-slip performance. The smooth section 7 of the anti-slip crossbar 5 can be rotated and connected with the anti-slip sleeve 4 in conjunction with the bearing.

[0036] In this embodiment, the anti-slip crossbar 5 passes sequentially through the flat steel 2 3 and the steel frame 1. The flat steel 2 3 is provided with a storage groove 2 31 through which the twisted groove section 6 of the anti-slip crossbar 5 passes. The steel frame 1 is provided with a storage groove 3 10 through which the twisted groove section 6 of the anti-slip crossbar 5 passes.

[0037] Both storage slot 2 31 and storage slot 3 10 can be used to reduce the protrusion of the anti-slip crossbar 5 on the steel frame 1 and the flat steel. By reducing the installation height of the anti-slip crossbar 5, it is easier for users to trip over it.

[0038] In this embodiment: a locking component 8 is provided at one end of the anti-slip crossbar 5. The locking component 8 is detachably connected to the steel frame 1. The locking component 8 includes a hinge seat 81, which is fixedly connected to one end of the anti-slip crossbar 5. A fixing plate 82 is hinged to the hinge seat 81, and a fastening bolt 83 is threadedly connected to the fixing plate 82. The side of the steel frame 1 is provided with three threaded grooves 9 for threaded connection of the fastening bolts 83.

[0039] When in use, after the spiral groove section 6 on the anti-slip crossbar 5 is worn flat, the threaded connection between the fastening bolt 83 and the steel frame 1 can be released. The anti-slip sleeve 4 provides rotational support for the anti-slip crossbar 5, which allows the anti-slip crossbar 5 to be rotated to adjust the usage area of ​​the spiral groove section 6, thereby improving the utilization rate of the spiral groove section 6 area. This improves the durability of the anti-slip crossbar 5 structure and extends the anti-slip performance of the steel grating.

[0040] The advantage of having three screw grooves 9 is that, since the twisted groove section 6 on the anti-slip crossbar 5 can only satisfy the anti-slip contact when adjusted to the upward direction, the twisted groove section 6 on the anti-slip crossbar 5 can be used in four equal parts. When the anti-slip crossbar 5 is adjusted to a 90-degree angle, the fastening bolt 83 can be threaded into one of the screw grooves 9 to limit the position of the fixing plate 82. When the twisted groove section 6 is used in the last area, since the fixing plate 82 can rotate on the hinge seat 81, the downward rotation of the fixing plate 82 can continue to use the existing screw grooves 9 to limit and fix the fixing plate 82. By improving the utilization rate of the screw grooves 9, the problem of protrusion when the fixing plate 82 is rotated to the top for fixing can be avoided.

[0041] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
