Description
Technical Field
[0001] The utility model relates to the technical field of building structure engineering, and particularly relates to an assembled reinforcement structure for truss web members and joints. Background Art
[0002] A truss structure is a structure formed by connecting rods hinged to each other at both ends, generally having a planar or spatial structure with triangular units. Its advantage is that the rods mainly bear tension or compression, which can give full play to the role of materials, save materials, and reduce the structural weight. A coal conveying trestle is a special industrial building, mainly a connecting corridor between power production, coal mine transportation plants and silo buildings, and plays a crucial role in the entire production process. Currently, the most widely used coal conveying trestle in various regions of China is the angle steel truss structure.
[0003] Most of the truss structures of coal conveying trestles in various regions of China have been used for a long time and are in a state of disrepair. Their working environment is high temperature, high humidity, and high dust, and the dust is rich in harmful elements such as sulfur. Currently, the general internal cleaning method is water flushing. Under such harsh environments for a long time, the exposed steel components, especially the truss web members and their joints, have peeling and falling of the surface anti-corrosion coating, and the steel components are gradually corroded and analyzed, the cross-section becomes smaller, and finally rust breaks, endangering the structural safety and posing a great risk of collapse, which will cause unpredictable damage consequences. Therefore, in addition to daily maintenance to maintain the anti-corrosion coating on the surface of steel components, it is also imperative to reinforce the corroded exposed steel components.
[0004] Currently, power, coal mine and other enterprises in various regions are all in normal production and operation. If the truss structure of the coal conveying trestle is reinforced by the conventional method of welding steel plates, not only is the welding volume large and the construction progress slow, but also a large amount of welding operations will inevitably affect the normal production of enterprises. Content of the Utility Model

Detailed implementation manners
[0033] To enable those skilled in the art to better understand the technical solutions in this application, the following will describe in detail the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. The described embodiments are only part of the embodiments of this application, rather than all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application.
[0034] As shown in Figure 1 and Figure 4 a truss web member and joint prefabricated reinforcement structure includes a first reinforcement member 22 and a connecting plate 21. The connecting plate 21 is spliced and fixed with the original joint plate 12 and together forms a new joint plate. The first reinforcement member 22 is arranged parallel to the original web member 11, and both ends of the first reinforcement member 22 are fixedly connected to the new joint plate.
[0035] As a specific implementation manner, in this embodiment, the connecting plate 21 is fixedly connected to the original joint plate 12 by welding. Both ends of the first reinforcement member 22 are respectively fixedly connected to the new joint plate through first bolt assemblies 221.
[0036] As a specific implementation manner, in this embodiment, one end of the connecting plate 21 facing the original joint plate 12 is provided with a receiving notch that fits the shape of the original joint plate 12. The original joint plate 12 is inserted into the receiving notch and fixedly connected to the edge of the receiving notch by welding. Exemplarily, the connecting plate 21 includes a web and wings at both ends of the web. The web and the wings together form a receiving notch for receiving the original joint plate 12, and the new joint plate formed by the original joint plate 12 and the connecting plate 21 has a square structure.
[0037] Furthermore, to facilitate the installation of the connecting plate 21, as shown in Figure 2 and Figure 4 a break 213 is provided on the connecting plate 21 on the side opposite to the open end of the receiving notch, and the break 213 divides the connecting plate 21 into two parts. For ease of description, the two parts divided by the break 213 are respectively named a first connecting part 211 and a second connecting part 212, and both the first connecting part and the second connecting part have an L-shaped structure.
[0038] The reason for such a design is as follows: First, it is convenient for installation. As shown in Figure 4 and Figure 6As shown in the figure, since some trusses (especially truss structures used in industry) have double-layer web members, that is, web members are provided on both sides of the original gusset plate 12 in the thickness direction, the connecting plate 21 needs to be inserted into the gap between the two layers of web members. However, during years of use, the truss will inevitably deform and have other problems. If the connecting plate 21 is a whole piece, due to its relatively large area and the need to be inserted into the gaps on both sides of the original gusset plate 12 (along the length direction of the original gusset plate 12) at the same time, the installation is often difficult, and it may even be impossible to insert due to deformation. By dividing the connecting plate 21 into two parts, the installation and fixation of the connecting plate 21 can be greatly facilitated. Second, due to the existence of processing errors, it is very difficult for the size of the accommodating notch to be exactly the same as that of the original gusset plate 12, and it is impossible to achieve a perfect fit. By dividing the connecting plate 21 into two parts, it can be ensured that both the first connecting part 211 and the second connecting part 212 of the connecting plate 21 can fit well with the original gusset plate 12, thereby ensuring the structural reliability after welding.
[0039] Furthermore, the fracture 213 of the connecting plate 21 is biased towards one side of the connecting plate 21. The reason for this design is that some trusses not only have web members but also vertical members 13. To ensure the structural strength of the new gusset plate, after the first connecting part 211 and the second connecting part 212 of the connecting plate 21 are installed on the original gusset plate 12, the fracture 213 between the first connecting part 211 and the second connecting part 212 needs to be connected and fixed. By offsetting the fracture 213, when the connecting plate 21 is installed on the original gusset plate 12, the fracture 213 is exposed outside, avoiding the vertical member 13 from blocking the fracture 213, and it is convenient to weld and fix the fracture 213.
[0040] Furthermore, the assembled and reinforced structure of the truss web member and node further includes a second reinforcing member 23. The second reinforcing member 23 is arranged in parallel with the original web member 11, and the first reinforcing member 22 and the second reinforcing member 23 are respectively located on both sides of the original web member 11. Both ends of the second reinforcing member 23 are fixedly connected to the new gusset plate through second bolt assemblies 231.
[0041] As a specific implementation manner, as Figure 6 shown, in this embodiment, both ends of the first reinforcing member 22 and the second reinforcing member 23 are fixedly connected to the connecting plate 21 of the new gusset plate.
[0042] Furthermore, in order to improve the reinforcement strength, as Figure 3 、 Figure 4 and Figure 5As shown, a number of reinforcement connecting plates 24 are arranged between the first reinforcement rod 22 and the second reinforcement rod 23 along the length direction, and both ends of the reinforcement connecting plate 24 are fixedly connected to the first reinforcement rod 22 and the second reinforcement rod 23 respectively through third bolt assemblies 241.
[0043] As a specific implementation manner, in this embodiment, three reinforcement connecting plates 24 are arranged between the first reinforcement rod 22 and the second reinforcement rod 23, and the three reinforcement connecting plates 24 are evenly arranged along the length direction.
[0044] Furthermore, as Figure 4 and Figure 5 shown, two first reinforcement rods 22 are arranged on one side of the original web member 11, and the two first reinforcement rods 22 are respectively located on both sides of the connecting plate 21 and are symmetrically arranged with respect to the connecting plate 21. Two second reinforcement rods 23 are arranged on the other side of the original web member 11, and the two second reinforcement rods 23 are respectively located on both sides of the connecting plate 21 and are symmetrically arranged with respect to the connecting plate 21. One end of the reinforcement connecting plate 24 is located in the gap between the two first reinforcement rods 22, and the other end of the reinforcement connecting plate 24 is located in the gap between the two second reinforcement rods 23.
[0045] As a specific implementation manner, in this embodiment, between the connecting plate 21 and the original gusset plate 12, and between the first connecting portion 211 and the second connecting portion 212 of the connecting plate 21, full penetration groove welding is used for connection. The first reinforcement rod 22 and the second reinforcement rod 23 are made of angle steel, and the cross-sectional dimensions are the same as those of the original web member 11.
[0046] The construction process of a truss web member and node assembled reinforcement structure includes the following steps:
[0047] First, dimension measurement. The dimensions of the original web member 11 and the original gusset plate 12 of the truss to be reinforced are actually measured.
[0048] Second, steel plate cutting. According to the dimensions measured in the first step, the connecting plate 21 is cut by cutting equipment, and the first connecting portion 211 and the second connecting portion 212 are obtained.
[0049] Third, install the connecting plate 21.
[0050] 3.1 As Figure 7 shown, insert the first connecting portion 211 into the gap between the original web member 11 on one side of the original gusset plate 12, and make the end of the first connecting portion 211 facing the vertical rod 13 pass through the gap of the vertical rod 13 and extend to the other side of the vertical rod 13, so as to realize the splicing of the first connecting portion 211 and the original gusset plate 12, and then fixedly connect the first connecting portion 211 and the original gusset plate 12 by welding.
[0051] 3.2 As Figure 8 shown, insert the second connection part 212 into the gap of the original web member 11 on the other side of the original gusset plate 12 to achieve the splicing of the second connection part 212 and the original gusset plate 12, and then fixedly connect the second connection part 212 and the original gusset plate 12 by welding.
[0052] 3.3 Weld and fix the fracture 213 of the connecting plate 21 to connect the first connection part 211 and the second connection part 212 into a whole.
[0053] 3.4 As Figure 9 shown, repeat the operations in steps 3.1 - 3.3 to install the connecting plate 21 on the other side.
[0054] Fourth, as Figure 10 shown, install the first reinforcement member 22. Mark and drill holes for the first reinforcement member 22 according to the positions of the mounting holes on the new gusset plate, and then fixedly connect the first reinforcement member 22 and the connecting plate 21 of the new gusset plate by using the first bolt assembly 221.
[0055] Fifth, as Figure 11 shown, install the second reinforcement member 23. Mark and drill holes for the second reinforcement member 23 according to the positions of the mounting holes on the new gusset plate, and then fixedly connect the second reinforcement member 23 and the connecting plate 21 of the new gusset plate by using the second bolt assembly 231.
[0056] Sixth, install the reinforcement connecting plate 24. Mark and drill holes for the first reinforcement bar and the second reinforcement bar according to the positions of the mounting holes on the reinforcement connecting plate 24, and then connect and fix the reinforcement connecting plate 24 to the first reinforcement member 22 and the second reinforcement member 23 respectively by using the third bolt assembly 241.
