The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not used to limit the utility model.

[0035] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0036] In our daily life, prefabricated load-bearing supports can be seen everywhere. They are responsible for bearing the weight and ensuring the normal operation of pipelines. Therefore, the quality of the load-bearing structure products in prefabricated supports is the key to the quality of prefabricated supports, and welding details are one of the important factors that determine the quality of these products.
[0037] The assembled load-bearing support and hanger products on the market are often only welded around the periphery of the connection position between the product's load-bearing connection parts and the fixing parts, such as Figure 1 、 Figure 3 The load-bearing products of the assembled bracket type shown in the figure are shown. The load-bearing connection parts and fixing parts are U-shaped edge guard and bottom plate. There is only a circle of ordinary weld bead between the U-shaped edge guard and the bottom plate. The holes on the bottom plate are used for anchor bolts or bolts. The U-shaped edge guard is used to install the vertical pole. When the vertical pole is pulled, the bottom plate will deform into the following shape. Figure 3 The "V"-shaped tensile crack a shown in the figure is formed when the load-bearing connection component and the fixing easily tear upward from the end point of the load-bearing connection component. If the subsequent load continues to increase, the tensile crack a will gradually expand, resulting in load-bearing failure and the loss of project safety.
[0038] In order to solve the above problems, the present application adds welding details of the load-bearing welding structure of the assembled bracket and proposes the following implementation plan for the welding details.
[0039] The present application provides a welded structure of an assembled bracket load-bearing product, which includes a load-bearing connecting component 100 and a fixing component 200. Figure 4 As shown, the top of one side of the load-bearing connection component 100 abuts against the fixing component 200, and the load-bearing connection component 100 and the fixing component 200 are welded together. The outer side of the intersection of the load-bearing connection component 100 and the fixing component 200 has an ordinary weld 310, and the load-bearing connection component 100 has a reinforcing weld 320 at the end of the weld where the fixing component 200 is connected. One end of the reinforcing weld 320 and one end of the ordinary weld 310 overlap to form a "J" shape, and the reinforcing weld 320 bends toward the inner side of the weld end and wraps around the weld end. Generally, the outer side of the bending position of the reinforcing weld 320 is arc-shaped. The arc-shaped outer side of the reinforcing weld 320 facilitates welding and makes the weld surface smooth. The reinforcing weld 320 is added to the load-bearing welding structure of the assembled bracket of this application, and the welding details are refined. The weld ends of the load-bearing connecting components 100 of the product are wrapped by reinforced welds 320. When the load-bearing connecting components 100 are stretched, the end points of their connections with the fixings 200 are reinforced and cannot be easily torn apart, thereby improving the load-bearing capacity of the entire assembled bracket load-bearing product and better ensuring project safety.
[0040] This utility model Figure 4 The example can also be applied to various load-bearing structural products processed by prefabricated bracket load-bearing welding. The reinforced weld wrapped around the end of the weld increases the welding strength of the joint position of the load-bearing connecting parts and the fixing parts, making it more difficult for the weld to be pulled apart from the end of the weld, and no opening will appear at the weld, thereby improving the load-bearing capacity of the entire load-bearing structural product and better ensuring project safety.
[0041] The following are application examples of welded structures with prefabricated support loads.
[0042] Example 1
[0043] like Figure 4 and Figure 5 As shown, the present application also provides an embodiment of a prefabricated bracket load-bearing product of the base type, which has a prefabricated bracket load-bearing welded structure 300 as described above, wherein the load-bearing connecting component 100 is a U-shaped edge guard, the fixing component 200 is a base plate, the side end of the U-shaped edge guard is welded to the base plate, and the two weld ends between the U-shaped edge guard and the base plate are respectively wrapped by two reinforcing welds 320. There is a "J"-shaped prefabricated bracket load-bearing welded structure 300 at each of the two end positions where the U-shaped edge guard is welded to the base plate. The outer side of the side end of the U-shaped edge guard is connected to the base plate with a common weld 310, the weld end of the U-shaped edge guard is wrapped with a reinforcing weld 320, and each of the two weld ends of the U-shaped edge guard has a "J"-shaped welding structure.
[0044] With displacement as the horizontal axis (unit: mm) and load as the vertical axis (unit: KN), the load-bearing test was carried out on the above embodiment 1 and the common base products on the market, and a load-displacement curve was drawn based on the test results. The product on the market is called non-welded, and the embodiment 1 is fully welded. The test results are shown as follows: Figure 11 shown.
[0045] refer to Figure 11 As can be seen, the initial forces in the two cases are roughly the same, but when the forces reach a certain value, the incomplete weld begins to fail, and the fully welded case clearly outperforms. Compared to the incomplete weld, the failure value in the fully welded case of Example 1 increases by approximately 20%, and the design value also increases by approximately 20%. In practical applications, regardless of whether the force is gravity or static load, the reinforced weld bead 320 at the end of the weld greatly improves project safety.
[0046] Example 2
[0047] like Figure 6As shown, an embodiment of a prefabricated bracket load-bearing product of the connector type has a prefabricated bracket load-bearing welding structure 300 as described above, the load-bearing connecting component 100 is a bending component, the fixing component 200 is a triangular piece, the triangular piece is fixed at the bending position of the bending component, and the prefabricated bracket load-bearing welding structure 300 is located at the splicing position of the bending component and the triangular piece. In this embodiment, the triangular piece is located on the outside of the bending angle of the bending component, and both ends of each welding edge of the triangular piece and the bending component are provided with a prefabricated bracket load-bearing welding structure 300, and two reinforcing welds 320 wrap the two weld point ends of the welding edge. The welding edges on the outside of the triangular piece and the bending component are both ordinary welds, and the weld point ends at both ends of each welding edge are respectively provided with reinforcing welds, and each welding edge has a "J"-shaped welding structure at both ends.
[0048] The triangular piece is welded to the edge of the bent part, such as Figure 6 As shown, when the bent ends of the bent part are connected to the vertical bar 1 and horizontal bar 2, respectively, and when the horizontal bar 2 is subjected to a certain load F, the product will open due to the force. At this time, the inner part where the bent part and the triangular piece meet will be prone to tearing due to the change in the bent part's angle, and the outer part will also be squeezed and dislocated, damaging the weld point. At both ends of each welded edge of the triangular piece, a "J"-shaped assembled bracket load-bearing weld structure 300 is installed to strengthen the weld end, ensuring that the inner side will not tear and the outer side will not be damaged by pressure.
[0049] Example 3
[0050] like Figure 7 As shown, unlike the second embodiment, the triangular piece in this embodiment is located inside the bend angle of the bent part. On each weld edge between the triangular piece and the bent part, the weld end away from the bend is equipped with a prefabricated bracket load-bearing weld structure 300, and a reinforcement weld bead wraps around the outer weld end. The outer side of the weld edge between the triangular piece and the bent part is a standard weld bead, with a reinforcement weld bead and a "J"-shaped weld structure only at the weld end away from the bend.
[0051] When the product is connected to the load, the first tearing should be at the outer welding end points of the inner and outer welding edges, that is, the ends of the welds away from the bending position. Strengthening the weld bead will increase the welding strength at this position to ensure that the weld is more difficult to pull apart.
[0052] Example 4
[0053] like Figure 8As shown, an embodiment of an assembled bracket load-bearing product of the pipe clamp type has a welded structure 300 for the assembled bracket load-bearing as described above, the load-bearing connecting component 100 is a pipe clamp, the fixing component 200 is a U-shaped block, the top ends of the two side walls of the U-shaped block are welded and fixed to the bent surface of the handle of the pipe clamp, the welded structure 300 for the assembled bracket load-bearing is located on two welding edges, the outer sides of the top ends of the two side walls of the U-shaped block are connected to the ordinary weld 310 of the pipe clamp, the two ends of each side wall are welded by two reinforcing welds respectively, and both ends have a "J"-shaped welding structure, and the two weld ends at both ends of each welding edge are wrapped by the reinforcing weld.
[0054] During use, the clamps are most susceptible to tearing at the welds to the U-shaped blocks due to the tension of the screws and the weight of the pipes, especially at the weld ends, i.e., the two weld points at each end of each welded edge. The two "J"-shaped prefabricated bracket load-bearing welded structures 300 at each end of each weld ensure that the weld points are encased in reinforced weld beads, enhancing weld strength and effectively reducing the risk of tearing at the weld ends, ensuring the safety of the bracket project.
[0055] Example 5
[0056] like Figure 9 and Figure 10 As shown, a support arm type prefabricated support load-bearing product has a prefabricated support load-bearing welded structure 300 as described above. The load-bearing connecting component 100 is a channel steel, and the fixing member 200 is a fixing plate. The fixing plate is fixed to the wall. The top of the channel steel is welded and fixed to the fixing plate. The prefabricated support load-bearing welded structure 300 is located at the connection between the channel steel and the fixing plate. The outer periphery of the channel steel is welded to connect the channel steel and the fixing plate. Two reinforcement welds 320 are bent to the turning end points of the two channel steels. The ordinary weld 310 and the reinforcement weld 320 form a "J"-shaped weld structure at two bends on the upper part of the channel steel.
[0057] In this embodiment, the channel steel is used as a support arm. When it is subjected to a certain load, the channel steel tends to bend downward due to the action of the force arm. The welding position between the fixed plate and the upper part of the channel steel is the weakest point, which is easy to tear. The "J"-shaped assembled bracket load-bearing welded structure 300 strengthens the welding strength of this position to prevent tearing from above the channel steel, which affects the safety and quality of the project.
[0058] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
[0059] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
