Description

Technical Field

[0001] This invention relates to the field of steel structure arc-shaped tripods, and in particular to an arc-shaped tripod for a steel structure performance venue and its installation method. Background Technology

[0002] Curved tripods are frequently used in steel structure demonstration venues to support and stabilize main beams. However, current technology presents several problems in the production of curved tripods:

[0003] 1. Due to the large span of the arc arm, which is generally 10 to 20 meters or even longer, in the steel industry, the larger the span of the profile, the more difficult it is to control the precision during the production process. This leads to a decrease in the precision of the arc arm after production. When assembling the arc triangular frame, if the arc arm is directly welded to the cross arm and column, it will result in a large positional deviation at the other end of the arc arm after welding at one end, making it impossible to assemble. This requires repeated adjustments, resulting in low construction efficiency and reduced product quality.

[0004] 2. Due to the large span of the arc arm, the corresponding length of the crossbeam increases accordingly. The crossbeam and the arc arm are fixed by welding steel pipes. When welding the steel pipes to the cross arm or arc arm, the different degrees of thermal expansion and cooling contraction of the weld surface will lead to internal stress and deformation problems. In particular, the back of the weld surface is a cavity, which cannot restrain or support the thermal stress of the steel, nor can it disperse the stress. At the same time, when using the arc tripod, because the cross arm has a long span, after long-term use, the joints need to bear a large load, which is prone to deformation, thus affecting the rigidity and strength of the cross arm and resulting in low safety.

[0005] 3. The assembled arc-shaped triangular frame is huge, and ordinary trucks can no longer meet the transportation needs. If special items are used for transportation, the corresponding procedures need to be handled in advance, which increases transportation costs and enterprise production costs, resulting in insufficient market competitiveness.

[0006] To address the above issues, improve assembly efficiency, enhance the overall strength of the arc-shaped tripod, and boost corporate competitiveness, it is necessary to propose an arc-shaped tripod for a steel structure performance venue and its installation method. Summary of the Invention

[0007] The purpose of this invention is to solve the above problems by proposing an arc-shaped tripod for a steel structure performance venue and its installation method.

[0008] To achieve the above objectives, the present invention provides the following technical solution: including a column, a horizontal arm mounted on the column, and an arc-shaped arm mounted on the horizontal arm and connected to the column, characterized in that it further includes a support column mounted on the column and the horizontal arm for connecting the arc-shaped arm, and a structural component mounted on the horizontal arm to enhance the strength of the connection node between the horizontal arm and the support column, wherein the structural component is an integral structural component or a split structural component, and the column and the arc-shaped arm are composed of steel pipes cut into multiple segments.

[0009] More preferably, the arc-shaped tripod is assembled from an upper steel structure and a lower steel structure. The upper steel structure includes some columns and arc-shaped arms, and the lower steel structure includes a cross arm, a connecting part, some columns and arc-shaped arms.

[0010] More preferably, the column is composed of a first column and a second column, and the arc-shaped arm is composed of a first arc-shaped arm, a second arc-shaped arm, a third arc-shaped arm and a fourth arc-shaped arm, with reinforcing plates installed on both sides of the first column, the second column, the first arc-shaped arm, the second arc-shaped arm, the third arc-shaped arm and the fourth arc-shaped arm.

[0011] More preferably, the outer sides of the first column and the second column, the first arc-shaped arm and the second arc-shaped arm are all equipped with connectors, and connecting plates are installed on the connectors by bolts.

[0012] More preferably, the column, cross arm and arc arm are all provided with grooves to facilitate the installation of integrated or separate structural components, and the grooves are covered with covers.

[0013] More preferably, the integrated structure includes a first connecting plate and a second connecting plate mounted on the groove, and a support member mounted on the first connecting plate and connected to the second connecting plate, which is integrally formed by multiple N-shaped structures.

[0014] More preferably, the first connecting plate and the second connecting plate are provided with positioning grooves that cooperate with the support member.

[0015] More preferably, the split structure includes several reinforcing members installed on the groove, the reinforcing members being independently installed in the groove at the same spacing.

[0016] A further preferred method for installing an arc-shaped tripod in a steel structure performance venue is characterized by the following steps:

[0017] Step 1. Cutting into segments: Cut the arc-shaped arm and column into several segments, and weld reinforcing plates to both ends of the cut arc-shaped arm and column;

[0018] Step 2. Install structural components: First, cut grooves on the columns, cross arms, and arc arms. The width of the grooves should not be less than the width of the connection between the support column and the column, cross arm, or arc arm. Then, install the structural components on the grooves by welding.

[0019] Step 3. Overall pre-welding: Place the components of the upper steel structure on the welding frame for pre-welding; place the components of the lower steel structure on the welding frame for pre-welding.

[0020] Step 4. Transfer welding: The upper and lower steel structures are moved to the welding operation area using hoisting equipment, and further welding operations are carried out on the previously pre-welded points;

[0021] Step 5. Packaging and Transportation: The upper and lower steel structures are packaged for easy transportation.

[0022] In a further preferred embodiment, when installing structural components in the second step, if a welded split structural component is used, the reinforcing component only needs to be directly welded to the groove of the horizontal arm, column, or arc arm; if a welded integrated structural component is used, the first connecting plate and the second connecting plate can be welded to the groove of the horizontal arm, column, or arc arm respectively, and then the support component can be installed in the positioning groove for welding.

[0023] The beneficial effects of this invention are as follows: By dividing the entire arc-shaped triangular frame into an assembly structure consisting of an upper steel structure and a lower steel structure, the problem of transporting oversized items is solved. Ordinary trucks can be used for transportation, saving transportation costs and time, and improving the competitiveness of enterprises.

[0024] By installing structural components at the connection nodes between the uprights, crossarms, and arc-shaped arms and the support columns, the structural components can constrain or support the weld back side during welding, preventing excessive thermal stress. They can also disperse and transfer the stress, avoiding excessive stress at the weld point and thus reducing the risk of deformation. During use, the structural components can enhance the strength and rigidity of the connection points, thereby improving the overall strength of the crossarm and enhancing the stability and safety of the arc-shaped tripod.

[0025] By adding reinforcing plates, the strength on both sides is enhanced when the multi-sectioned columns and curved arms are assembled.

[0026] By designing the arc arm as a multi-segment assembly and welding structure, the problem of inaccurate positioning and welding due to excessive curvature deviation during the overall assembly of the arc arm is solved. By cutting it into multiple arc segments for assembly, curvature deviation can be effectively controlled, resulting in higher precision and improved assembly efficiency.

[0027] By using connectors, the upper and lower steel structures can be quickly assembled using connecting plates and bolts, which serves to pre-fix and increase connection strength, thereby improving the overall assembly efficiency of the arc-shaped triangular frame. Attached Figure Description

[0036] The following is a detailed description of the arc-shaped tripod for a steel structure performance venue and its installation method, with reference to the accompanying drawings.

[0037] See appendix Figures 1 to 7As shown in this embodiment, an arc-shaped tripod for a steel structure performance venue and its installation method include a column 1, a horizontal arm 2 bolted to the column 1, and an arc-shaped arm 3 welded to the horizontal arm 2 and connected to the column 1. The feature is that it also includes a support column 4 welded to the column 1 and the horizontal arm 2 for connecting the arc-shaped arm 3, and a structural component 5 welded to the horizontal arm 2 to enhance the strength of the connection node between the horizontal arm 2 and the support column 4. The structural component 5 is either an integral structural component or a split structural component. The column 1 and the arc-shaped arm 3 are composed of multiple sections of steel pipe. The arc-shaped triangular frame is assembled from an upper steel structure 6 and a lower steel structure 7. By dividing the entire arc-shaped triangular frame into an assembly structure of upper steel structure 6 and lower steel structure 7, the problem of transporting oversized objects is solved. Ordinary trucks can be used for transportation, saving transportation costs and time, and improving the company's competitiveness. By designing the arc-shaped arm 3 as a multi-segment assembly and welding structure, the problem of inaccurate positioning and welding due to excessive curvature deviation during the overall assembly of the arc-shaped arm 3 is solved. By cutting it into multiple arc segments for assembly, curvature deviation can be effectively controlled, resulting in higher precision and improved assembly efficiency.

[0038] The upper steel structure 6 includes a portion of the uprights 1 and the arc-shaped arms 3. The lower steel structure 7 includes a horizontal arm 2, a support column 4, a portion of the uprights 1 and the arc-shaped arms 3. The uprights 1 are composed of a first upright 11 and a second upright 12. The arc-shaped arms 3 are composed of a first arc-shaped arm 31, a second arc-shaped arm 32, a third arc-shaped arm 33, and a fourth arc-shaped arm 34. Reinforcement is installed on both sides of the first upright 11, the second upright 12, the first arc-shaped arm 31, the second arc-shaped arm 32, the third arc-shaped arm 33, and the fourth arc-shaped arm 34. The reinforcing plate 9, the first column 11 and the second column 12, the first arc arm 31 and the second arc arm 32 are all equipped with connectors 8 on their outer sides, and connecting plates 81 are installed on the connectors 8 by bolts; by setting the reinforcing plate 9, the strength of both sides of the multi-segmented column 1 and arc arm 3 is enhanced when they are assembled; by setting the connectors 8, the upper steel structure 6 and the lower steel structure 7 are quickly assembled by using the connecting plates 81 and bolts, which plays a role in pre-fixing and increasing the connection strength, thereby improving the overall assembly efficiency of the arc triangular frame.

[0039] The column 1, crossarm 2, and arc-shaped arm 3 are all provided with grooves 50 to facilitate the installation of integrated or separate structural components. A cover plate 53 is installed on each groove 50. The integrated structure includes a first connecting plate 511 and a second connecting plate 512 installed on the groove 50, and a support member 513 installed on the first connecting plate 511 and connected to the second connecting plate 512, formed by the integral combination of multiple N-shaped structures. The first connecting plate 511 and the second connecting plate 512 are provided with positioning grooves 514 that mate with the support member 513. The separate structure includes several reinforcing members 521 installed on the groove 50, with the reinforcing members 521 independently installed within the groove 50 at equal intervals. Through the arrangement of the structural members 5, the column 1, crossarm 2, and arc-shaped arm 3 are integrated with the support member 513. A structural component 5 is installed at the connection node between arm 3 and support column 4. During welding, the structural component 5 can constrain or support the back of the weld, preventing excessive thermal stress and distributing the stress to avoid excessive stress at the weld point, thereby reducing the risk of deformation. In use, the structural component 5 can enhance the strength and rigidity of the connection point, thereby improving the overall strength of the cross arm 2 and enhancing the stability and safety of the arc-shaped tripod. Through the integrated structural component, the back of the weld point is supported by the second connecting plate 512. During welding, the stress is distributed to the second connecting plate 512 and evenly transferred to the first connecting plate 511 through the integrated support component 513, thereby achieving a dispersion effect and further reducing the risk of weld point deformation.

[0040] The assembly method for the arc-shaped tripod of this invention is as follows:

[0041] Step 1. Cutting into segments: Cut the arc arm 3 and the column 1 into several segments respectively, and weld the reinforcing plates 9 to both ends of the cut arc arm 3 and the column 1;

[0042] Step 2. Install structural component 5: First, cut grooves 50 on column 1, cross arm 2 and arc arm 3. The width of the grooves 50 should not be less than the width of the connection between the support column 4 and column 1 or cross arm 2 or arc arm 3. Then, install the structural component 5 on the grooves 50 by welding.

[0043] Step 3. Overall pre-welding: Place the components of the upper steel structure 6 on the welding frame for pre-welding, so that the horizontal arm 2 and some of the columns 1, support columns 4 and arc arms 3 are welded together; place the components of the lower steel structure 7 on the welding frame for pre-welding, so that some of the columns 1, support columns 4 and arc arms 3 are welded together.

[0044] Step 4. Transfer welding: Move the upper steel structure 6 and the lower steel structure 7 to the welding operation area using hoisting equipment, and carry out further welding work on the previously pre-welded points. At the same time, the next arc-shaped tripod can be operated in the pre-welded area, improving production efficiency.

[0045] Step 5. Packaging and Transportation: The upper steel structure 6 and the lower steel structure 7 are packaged for easy transportation.

[0046] The assembly operation at the construction site is as follows: After the arc-shaped triangular frame is transported to the site, the upper steel structure 6 and the lower steel structure 7 are removed from the truck using hoisting equipment. The upper steel structure 6 and the lower steel structure 7 are then placed on the ground according to the assembly direction. They are connected and fixed by bolts passing through the connector 8 and the connecting plate 81. The joints are then welded. Finally, the entire arc-shaped triangular frame is hoisted up using hoisting equipment and installed on the designated pre-embedded foundation.

[0047] The scope of protection of this invention is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this invention.
