Description

Technical Field

[0001] This utility model relates to the field of steel structure engineering technology, and in particular to a high-strength energy-saving steel structure for steel structure engineering. Background Technology

[0002] Steel structures are a type of building structure. Compared to traditional reinforced concrete structures, steel structures consume less energy and have good inherent strength, making them a widely adopted form of green building. Steel structures are typically connected using bolts and nuts. However, in existing connection methods, the bolt heads and nuts are often exposed on the outside, making them susceptible to corrosion. The threads extending beyond the nut are also prone to corrosion, and the protruding bolt heads and nuts result in poor surface smoothness of the entire steel structure.

[0003] To address the aforementioned issues, we propose a high-strength, energy-saving steel structure for steel structure engineering. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background technology by proposing a high-strength energy-saving steel structure for steel structure engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength energy-saving steel structure for steel structure engineering, comprising a positioning plate, a first connecting plate, a second connecting plate, and two support plates. The upper and lower ends of the two support plates are fixedly connected to the first connecting plate and the positioning plate, respectively. Four sleeves are fixedly installed on the upper side of the positioning plate, and the four sleeves are located at the four corners of the positioning plate. A through hole corresponding to the sleeve is opened on the lower side wall of the positioning plate. Each sleeve is provided with a mating mechanism.

[0006] The second connecting plate is located below the positioning plate. The upper wall of the second connecting plate is fixedly provided with threaded tubes corresponding to the first through hole at the four corners. The threaded tubes are vertically arranged and connected to the positioning plate by hexagonal head bolts.

[0007] In the above-mentioned high-strength energy-saving steel structure for steel structure engineering, the fitting mechanism includes an insert block disposed inside the sleeve. The insert block is cylindrical and has a through hole two in the middle. The upper end of the insert block is fixedly connected to a hexagonal tube located outside the sleeve. The interior of the hexagonal tube is provided with a hexagonal groove communicating with the through hole two.

[0008] In the above-mentioned high-strength energy-saving steel structure for steel structure engineering, the upper wall of the connecting plate one is welded with steel material one, and the lower wall of the connecting plate two is welded with steel material two.

[0009] In the aforementioned high-strength energy-saving steel structure for steel structure engineering, the lower side wall of the connecting plate two is provided with a vent hole that communicates with the threaded pipe.

[0010] In the aforementioned high-strength energy-saving steel structure for steel structure engineering, the two support plates are arranged in an arc shape.

[0011] In the high-strength energy-saving steel structure used in the above-mentioned steel structure engineering, the distance between the upper end of the hexagonal tube and the lower side wall of the connecting plate is greater than the length of the hexagonal head bolt.

[0012] Compared with existing technologies, the advantages of this high-strength energy-saving steel structure for steel structure engineering are as follows:

[0013] This utility model places the connecting bolts on the inside of the steel structure. The hexagonal head of the bolt is located in the hexagonal groove of the hexagonal tube, and the bolt shank passes through the positioning plate and is inserted into the threaded tube on the connecting plate 2, so that steel material 1 and steel material 2 are indirectly fastened. This not only effectively reduces the risk of bolt corrosion, but also improves the flatness of the steel structure surface. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A high-strength energy-saving steel structure for steel structure engineering includes a positioning plate 1, a connecting plate 1 2, a connecting plate 2 4, and two support plates 3. The upper and lower ends of the two support plates 3 are fixedly connected to the connecting plate 1 2 and the positioning plate 1, respectively. The two support plates 3 are arranged in an arc shape, which is beneficial to improving the support strength of the support plates 3. The connecting plate 1 2 and the positioning plate 1 are arranged in parallel, and the four corner points of the support plate 3 are located at the middle of the corresponding edge lines of the connecting plate 1 2 and the positioning plate 1, respectively. Four sleeves 5 are fixedly installed on the upper side of the positioning plate 1. The four sleeves 5 are located at the four corners of the positioning plate 1, and the lower side wall of the positioning plate 1 is provided with through holes 1 6 corresponding to the sleeves 5. Each sleeve 5 is provided with a mating mechanism.

[0020] The mating mechanism includes an insert 9 disposed inside the sleeve 5. The insert 9 is cylindrical and has a through hole 7 in the middle. The outer diameter of the insert 9 is smaller than the inner diameter of the sleeve 5. The upper end of the insert 9 is fixedly connected to a hexagonal tube 10 located outside the sleeve 5. The interior of the hexagonal tube 10 is provided with a hexagonal groove 11 that communicates with the through hole 7.

[0021] Connecting plate 2 4 is located below positioning plate 1. Threaded tubes 8, corresponding to through holes 1 6, are fixedly installed at the four corners of the upper wall of connecting plate 2 4. The threaded tubes 8 are vertically positioned and connected to positioning plate 1 by hexagonal head bolts. The bolt heads of the hexagonal head bolts match the hexagonal slots 11. The connection process is as follows:

[0022] Insert the hexagonal head bolt downwards from the upper side of the hexagonal tube 10, so that the bolt shank passes through the second through hole 7 and the first through hole 6. The bolt head of the hexagonal head bolt extends into the hexagonal groove 11. By rotating the hexagonal tube 10, the bolt shank is rotated, so that the threaded shank extends into the threaded tube 8 and fits tightly with it, thereby fixing the distance between the positioning plate 1 and the second connecting plate 4. The inner diameter of the second through hole 7 and the first through hole 6 is larger than the outer diameter of the bolt shank.

[0023] The lower side wall of the connecting plate 2 4 is provided with an air guide hole 14 that communicates with the threaded tube 8 to reduce the air resistance when the bolt rod and the threaded tube 8 move together. The distance between the upper end of the hexagonal tube 10 and the lower side wall of the connecting plate 2 is greater than the length of the hexagonal head bolt. The inner wall of the hexagonal groove 11 is coated with lubricant.

[0024] Steel material 12 is welded to the upper wall of connecting plate 12, and steel material 23 is welded to the lower wall of connecting plate 24. Steel material 12 and steel material 23 are relatively fixed under the connection of this steel structure, which not only effectively reduces the risk of bolt corrosion, but also improves the flatness of the steel structure surface.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
