Description

[Technical field]

[0001] The invention belongs to the technical field of building structures, and in particular relates to a snap-on fixed connection structure of orthogonal steel bars on a steel bar truss. [Background technology]

[0002] In the prior art, a steel skeleton needs to be placed in the load-bearing wall of a building during the manufacturing process, and the steel skeleton includes a steel truss, horizontal steel bars, and clip stirrups. The steel truss also includes column steel bars and a number of steel mesh connecting plates arranged on the column steel bars. In the prior art, the steel bars are usually fixed to each other by manual binding or mechanical binding, manual welding or automatic welding. With the national advocacy of building industrialization, many steel bar deep processing technologies have emerged. Among them, the automated welded steel bar truss is one of the steel bar deep processing products. The emergence of this product has brought new topics to the processing of steel cages. Because the steel truss can only provide stiffness in one direction, and the steel cage is a three-dimensional component, it is necessary to fix the steel bars or trusses in the vertical and horizontal directions together. Common methods include manual or machine binding, manual or mechanical welding. Regardless of whether binding or welding is used, the connection method is very slow and inefficient. Usually, in order to ensure the construction period, a large amount of manpower is needed to complete the above work, and the production cost is high. Moreover, manual binding often results in the binding structure not meeting the requirements due to fatigue or inadequate supervision, causing the bound steel bars to loosen, and in severe cases, it may lead to safety accidents.

[0003] Therefore, it is necessary to provide a new snap-on fixed connection structure for orthogonal steel bars on a steel bar truss to solve the above problems. [Summary of the invention]

[0004] The main purpose of the present invention is to provide a snap-on fixed connection structure for orthogonal steel bars on a steel truss, which can quickly and firmly fix the horizontal steel bars on the steel truss, greatly improving the operating efficiency and reducing the production cost.

[0005] The present invention achieves the above-mentioned purpose through the following technical scheme: a snap-in fixed connection structure of orthogonal steel bars on a steel bar truss, which includes a steel bar connecting plate truss, horizontal steel bars, and a snap-in riveted plate for fixing the horizontal steel bars on the steel bar connecting plate truss, the steel bar connecting plate truss includes column steel bars and connecting plates, the snap-in riveted plate is an overall long sheet-like structure and has a first snap portion and a second snap portion extending outward at both ends perpendicular to the long side direction, the connecting plate is provided with a first snap-in socket that is snapped with the first snap-in portion, and a second snap-in socket that is snapped with the second snap-in portion, the sheet-like portion of the snap-in riveted plate presses the horizontal steel bars downward and tightly against the connecting plate from both sides and includes a first tensioning portion that applies a downward pressure force to the horizontal steel bars and is vertically downward, and a second tensioning portion that applies an oblique force to the horizontal steel bars and is obliquely arranged.

[0006] Furthermore, the widths of the first buckle portion and the second buckle portion increase gradually along the direction of being inserted into the corresponding bayonet, and both include a first riveted edge that abuts against an opening edge of the first bayonet or the second bayonet.

[0007] Furthermore, the first riveting edge is a beveled edge, and the angle between the first riveting edge and the vertical direction is smaller than the friction angle between the two materials of the snap riveting sheet and the connecting sheet.

[0008] Furthermore, the first riveting edge is arranged on a side opposite to the first buckle portion and the second buckle portion.

[0009] Furthermore, the first buckle portion and the second buckle portion further include a second riveting edge opposite to the first riveting edge.

[0010] Furthermore, the second riveting edge is a beveled edge or a right-angled edge, and the angle between the beveled edge and the vertical direction is smaller than the friction angle between the two materials of the snap riveting sheet and the connecting sheet.

[0011] Furthermore, two parallel vertically distributed column steel bars are provided in the steel bar connecting plate truss, and a plurality of connecting plates are welded on the two column steel bars to form a ladder structure, and the length of the connecting plate is greater than the distance between the two column steel bars, so that both ends of the connecting plate extend outwardly beyond the outside of the column steel bars.

[0012] Furthermore, the horizontal steel bars are located outside the column steel bars.

[0013] Compared with the prior art, the beneficial effect of the snap-in type fixed connection structure of orthogonal steel bars on a steel truss of the present invention is that: by designing a snap-in rivet plate structure and cooperating with the reserved slots provided on the connection plate, when fixing the horizontal steel bars, it is only necessary to knock the snap parts at both ends of the snap-in rivet plate into the reserved slots. On the one hand, the assembly and fixing efficiency of the horizontal steel bars is greatly improved, and on the other hand, the connection strength is also greatly improved, thereby improving the overall strength of the connection structure between the steel truss and the horizontal steel bars, and improving the safety and reliability of the overall structure.

[Specific implementation method]

[0020] Embodiment 1:

[0021] Please refer to Figure 1-Figure 3 The snap-in fixed connection structure 100 of orthogonal steel bars on the steel bar truss of this embodiment includes a steel bar connecting plate truss 1, horizontal steel bars 2 erected on the steel bar connecting plate truss 1, and a snap-in riveting plate 3 fixing the horizontal steel bars 2 on the steel bar connecting plate truss 1. The steel bar connecting plate truss 1 includes a column steel bar 11 and a connecting plate 12. The snap-in riveting plate 3 is an overall long sheet structure and has two ends extending outward perpendicular to the long side direction and provided with a first snap portion 31 and a second snap portion 32. The connecting plate 12 is provided with a first snap-in opening 121 snapped with the first snap-in opening 31 and a second snap-in opening 122 snapped with the second snap-in opening 32. The sheet portion of the snap-in riveting plate 3 presses the horizontal steel bar 2 down and tightly against the steel bar connecting plate truss 1 from the outside and includes a first tensioning portion 33 that applies a downward pressure force to the horizontal steel bar 2 and is vertically downward, and a second tensioning portion 34 that applies an oblique force to the horizontal steel bar 2 and is obliquely arranged.

[0022] The width of the first buckle portion 31 and the second buckle portion 32 increases gradually along the direction of the corresponding bayonet, and both include a first riveting edge 311 that abuts against the opening edge of the first bayonet 121 or the second bayonet 122. The first riveting edge 311 is a bevel, and the angle a between the first riveting edge 311 and the vertical direction is smaller than the friction angle of the two materials of the buckle riveting sheet 3 and the connecting sheet 12. This embodiment utilizes the abutment between the first riveting edge 311 and the opening edge of the corresponding bayonet, and utilizes the friction force to achieve the clamping of the two.

[0023] The first riveting edge 311 is disposed on a side of the first buckle portion 31 opposite to the second buckle portion 32. The first buckle portion 31 or the second buckle portion 32 further includes a second riveting edge 312 opposite to the first riveting edge 311. The second riveting edge 312 is a hypotenuse or a right-angled edge.

[0024] In other embodiments, the buckle portion may also be configured as a contractible or expandable umbrella-shaped conical structure, and the bayonet may be configured as a circular structure accordingly.

[0025] Two parallel vertically distributed column steel bars 11 are arranged in the steel bar connecting plate truss 1, and a plurality of connecting plates 12 are welded on the two column steel bars 11 to form a ladder-like structure. The length of the connecting plate 12 is greater than the distance between the two column steel bars 11, so that both ends of the connecting plate 12 extend outwardly beyond the outside of the column steel bars 11.

[0026] The horizontal reinforcement 2 is located outside the column reinforcement 11 .

[0027] In this embodiment, the first tensioning portion 33 provides a downward pulling force to press the horizontal steel bar 2 downward, and the second tensioning portion 34 provides an oblique downward pulling force, which can be divided into a horizontal outward pulling force and a vertical downward pulling force. Among them, the horizontal outward pulling force can ensure that the horizontal steel bar 2 is close to the column steel bar 11 to prevent it from horizontal sliding; the other vertical downward pulling force presses the horizontal steel bar 2 downward, and together with the first tensioning portion 33 prevents the horizontal steel bar 2 from having freedom in the vertical direction, thereby realizing the fixed connection of the horizontal steel bar 2.

[0028] When fixing the horizontal steel bar 2, first use a hammer to knock the first buckle part 31 at one end of the buckle riveting plate 3 into the first buckle slot 121 to fix it; then, the sheet-like part of the buckle riveting plate 3 is passed around the horizontal steel bar 2; then, the second buckle part 32 at the other end of the buckle riveting plate 3 is knocked into the second buckle slot 122 with a hammer to complete the fixed connection; the process of hammering in the second buckle part 32, on the one hand, realizes the compression of the horizontal steel bar 2, and on the other hand, adjusts the length of the buckle riveting plate 3, so that the tension of the buckle riveting plate 3 can be adjusted.

[0029] The snap-on fixed connection structure 100 of the orthogonal steel bars on the steel truss of this embodiment is designed with a snap-on rivet plate structure, which cooperates with the reserved slots provided on the connection plate. When fixing the horizontal steel bars, it is only necessary to knock the snap parts at both ends of the snap-on rivet plate into the reserved slots. On the one hand, the assembly and fixing efficiency of the horizontal steel bars is greatly improved, and on the other hand, the connection strength is also greatly improved, thereby improving the overall strength of the connection structure between the steel truss and the horizontal steel bars, and improving the safety and reliability of the overall structure.

[0030] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
