Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, in particular to a building steel structure. Background Art

[0002] In order to improve the thermal insulation effect of temporary buildings, thermal insulation materials are usually set between the metal plates on the inner and outer sides. However, for the purpose of lightness, the metal plates are usually thin plates, and there is no connection between the metal plates and the thermal insulation materials. They can only be connected to each other around the metal plates and fixed to each other by bonding. Therefore, the overall strength is not good, and it is necessary to improve it. In addition, the current building panels have a single function and need to be improved. Patent CN201620335883.8 discloses a steel structure building panel, the outermost sides of which are solar panels and colored sand layers. The solar panels can convert solar energy into electrical energy, and the colored sand layer can be used for corrosion prevention in rainy days. However, it is necessary to manually flip the building panels according to the needs of the weather to achieve power generation in sunny weather and corrosion prevention in rainy days. However, due to the rotation, there are gaps between the building panels, and the sealing of the temporary buildings is not good, which will easily lead to wind and water ingress and cause corrosion of the building panels; and hot air can easily flow out of the gaps, and the thermal insulation is not good. In patent C N201710296326.7 proposes a building steel structure, including an inner panel and an outer panel, a thermal insulation layer is provided between the inner panel and the outer panel, a plurality of compression springs are connected between the inner panel and the outer panel, and the compression springs are embedded in the thermal insulation layer. A solar panel is laid on the outer surface of the inner panel, an anti-corrosion layer is provided on the outer surface of the outer panel, and an illumination sensor is provided on the anti-corrosion layer. By arranging a sealing plate on the outer side of the anti-corrosion layer and pushing the sealing plate to move left and right through a power drive device I, the gaps between different building panels can be blocked, so that the constructed temporary building has good sealing and thermal insulation properties.

[0003] Although the above-mentioned prior art can solve the sealing problem, the internal arrangement of the driving device and the sensor structure will undoubtedly increase the difficulty of construction and the cost of temporary building structures. Utility Model Content

The steel rods are hollow inside, and connecting plates are fixed near both ends. The two connecting plates are provided with threaded connecting holes through them. A connecting piece is slidably connected inside each side, and a bolt is inserted inside the connecting piece. The bolt is threadedly connected to the connecting plate away from the end of the connecting piece, and a plug-in rod is fixed on the side of the steel rod, and the plug-in rod is located in the middle of the steel rod.

[0006] Furthermore, the connecting member includes a waist-shaped through groove arranged inside the side, a sliding groove is arranged on the inner wall of the waist-shaped through groove, a connecting block is slidably connected inside the sliding groove, and the bolt is inserted into the connecting block.

[0017] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0018] Please also refer to Figures 1 to 5 , the building steel structure of the embodiment of the utility model will be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 As shown, the building steel structure includes a steel rod 1 and a connecting head 2 for connecting the steel rod 1, the connecting head 2 includes four side edges 3, and is a hollow structure surrounded by the four side edges 3, the four side edges 3 can be used to install the steel rod 1, the steel rod 1 is hollow inside, and connecting plates 4 are fixed near both ends, and the two connecting plates 4 are provided with penetrating threaded connection holes 5, each side edge 3 is slidably connected with a connecting piece, and a bolt 6 is inserted in the connecting piece, and the bolt 6 is threadedly connected to the connecting plate 4 away from the connecting piece end, and a plug-in rod 7 is fixed to the side of the steel rod 1, and the plug-in rod 7 is located in the middle of the steel rod 1.

[0020] As an embodiment, the connecting member includes a waist-shaped through groove 9 arranged inside the side 3, a slide groove 8 is arranged on the inner wall of the waist-shaped through groove 9, a connecting block 10 is slidably connected inside the slide groove 8, and the bolt 6 is inserted into the connecting block 10.

[0021] Among them, a spring seat 11 is fixed on the inner wall of the waist-shaped through groove 9, a spring 12 is fixed at the end of the spring seat 11 away from the waist-shaped through groove 9, and the other end of the spring 12 is fixed to the side of the connecting block 10. Two spring seats 11 are symmetrically arranged about the middle part of the waist-shaped through groove 9.

[0022] Four steel rods 1 can be connected and installed on the side of each connecting head 2, and the bolts 6 are inserted through the connecting block 10 and threadedly fixed to the connecting plate 4 inside the steel rod 1. The connecting block 10 can move left and right along the slide groove 8 inside the waist-shaped through groove 9, and the springs 12 arranged on both sides of the connecting block 10 can maintain the connecting block 10 in a balanced state without external force.

[0023] At the same time, rubber plates 13 are fixedly bonded on both sides of the steel rod 1. The inside of the rubber plate 13 is hollow, and the two ends of the rubber plate 13 are inclined at 45 degrees. A through hole 14 is provided in the middle of the rubber plate 13 for the insertion rod 7 to pass through.

[0024] Based on the above technical background, this embodiment is applied to temporarily constructed heat-insulating buildings. Every four steel rods 1 and four connectors 2 form a small structural unit. A plug-in rod 7 is set on the side of two oppositely arranged steel rods 1 inside the structural unit. The plug-in rod 7 is used to plug in the building board. After fixing the steel rod 1 on one side, the building board is inserted, and then the steel rod 1 on the other side of the building board is installed to keep the building board flippable between the four steel rods 1. At the same time, after the building board is plugged in, its four sides are in conflict with the sides of the four rubber plates 13. In the absence of external force, the building board will not rotate spontaneously due to the conflict between the rubber plates 13.

[0025] When the building board needs to be flipped, one side of the building board is pressed, and the building board starts to rotate, releasing the interference with the two rubber plates 13 therein, and when flipped to the other side, it conflicts with the rubber plates 13 again. Meanwhile, during the flipping process, the two steel rods 1 that are not plugged into the building board are active. Specifically, after the steel rod 1 conflicts with the rubber plates 13 on the inside, it drives the connecting block 10 connected thereto to have a small sliding stroke, and when the spring 12 is reset, the steel rod 1 is reset, and then after the building board is flipped, the rubber plates 13 continue to conflict with the side surfaces of the building board to avoid gaps, and the rubber plates 13 have good ductility and elasticity, further improving the sealing performance.

[0026] The length of the side 3 is set equal to the width of the steel rod 1, and the side 3 is convenient for installation with the steel rods 1 in four directions to form an overall square structural unit, which is convenient for extension to thermal insulation buildings of different sizes.
