Description

Technical Field

[0001] The utility model relates to steel structure construction, and particularly relates to a temporary support structure for a truss. Background Art

[0002] Trusses are widely used in steel structures because of their light weight, high stiffness, and convenient connection. During the installation of a truss, temporary supports need to be set at its node positions. To ensure stability, the temporary supports are generally fixedly connected to the truss, and then the temporary supports can be removed after the truss installation is completed. Currently, some trusses are combined with cable structures. During the construction of this combined structure, temporary supports need to be set first, then the cable structure is tensioned, and finally the truss installation is completed. Among them, during the tensioning process of the cable structure, the truss will undergo a small displacement, and the temporary supports are fixedly connected to the truss node positions. Therefore, there may be potential damage hazards at the truss nodes, and in severe cases, it may even cause the truss to deform. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a temporary support structure for a truss, which can avoid the damage of the truss nodes caused by the tensioning of the cable structure.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A temporary support structure for a truss includes a falsework and a support column. The falsework is spliced upward by several falsework units. A bearing frame is installed on the top surface of the topmost falsework unit. A bearing plate is installed on the top surface of the bearing frame. A sliding plate is placed on the top surface of the bearing plate. The upper end of the support column is a matching structure for temporarily supporting the truss, diagonal braces are provided around the lower part, and a bottom plate is provided at the lower end. The bottom plate is placed on the sliding plate and its moving range is within the sliding plate. The diagonal braces support on the bearing plate and can be connected to the bearing plate through bolt assemblies.

[0006] Preferably, the diagonal brace includes a diagonal rod and a support. One end of the diagonal rod is connected to the support column, and the other end is connected to the support. Bolt holes are provided on the support.

[0007] Preferably, a stiffening plate is provided between the bottom plate and the support column.

[0008] Preferably, the falsework unit adopts a lattice standard section.

[0009] Preferably, the sliding plate adopts a polytetrafluoroethylene plate.

[0010] Preferably, the bearing frame is spliced by steel sections.

[0011] Preferably, the bearing plate adopts a steel plate.

[0012] Preferably, the support column adopts a steel section.

[0013] The beneficial effects of the utility model are:

[0014] After the temporary support is installed, the diagonal bracing member is not connected to the load-bearing plate first, that is, the temporary support is not rigidly connected to the truss node. Thereafter, during the tensioning process of the cable structure, the truss will undergo a small displacement. The truss transmits the force by driving the support column and the bottom plate to slide along the slide plate. In this way, the damage to the truss node caused by the tensioning of the cable structure can be avoided. After the tensioning of the cable structure is completed, the diagonal bracing member is connected to the load-bearing plate, that is, the temporary support is rigidly connected to the truss node. Thereafter, the installation of the truss can be completed safely and stably. After the truss is installed, the temporary support is disassembled. Description of the Drawings

[0018] The present invention will be further described below with reference to the drawings and embodiments.

[0019] This embodiment discloses a truss temporary support structure, as shown in Figure 1 and Figure 2 , which includes a jig and a support column 1; wherein: as shown in Figure 1 , the jig is spliced upward by a plurality of jig units 9, the top surface of the topmost jig unit 9 is provided with a load-bearing frame 6, the top surface of the load-bearing frame 6 is provided with a load-bearing plate 4, and a slide plate 3 is placed on the top surface of the load-bearing plate 4; as shown in Figure 1 and Figure 2 , the upper end of the support column 1 is a matching structure for temporarily supporting the truss, diagonal bracing members 8 are provided around the lower part, and a bottom plate 2 is provided at the lower end. The bottom plate 2 is placed on the slide plate 3 and the moving range is within the slide plate 3. The diagonal bracing member 8 supports on the load-bearing plate 4 and can be connected to the load-bearing plate 4 through a bolt assembly 5.

[0020] As shown in Figure 1 and Figure 2 , in this embodiment, preferably: the diagonal bracing member 8 includes a diagonal rod 81 and a support 82. One end of the diagonal rod 81 is connected to the support column 1 and the other end is connected to the support 82. A bolt hole is provided on the support 82; a stiffening plate 7 is provided between the bottom plate 2 and the support column 1 to ensure the stability and reliability of the structure.

[0021] As shown in Figure 1As shown, in this embodiment, preferably: The jig unit 9 adopts a lattice standard section, and the size can be 2m×2m×2m.

[0022] In this embodiment, preferably: The sliding plate 3 adopts a polytetrafluoroethylene plate; the load-bearing frame 6 is spliced by section steel; the load-bearing plate 4 adopts a steel plate; the support column 1 adopts section steel.

[0023] After the temporary support is installed, the diagonal bracing member 8 is not connected to the load-bearing plate 4 first, that is, the temporary support is not rigidly connected to the truss node. Thereafter, during the tensioning process of the cable structure, the truss will undergo a small displacement (through design calculation and demonstration, the displacement range does not exceed 100mm). The truss drives the support column 1 and the bottom plate 2 to slide along the sliding plate 3 to transfer the force, so as to avoid the damage of the truss node caused by the tensioning of the cable structure. After the tensioning of the cable structure is completed, the diagonal bracing member 8 is connected to the load-bearing plate 4, that is, the temporary support is rigidly connected to the truss node. Thereafter, the truss installation can be completed safely and stably. After the truss is installed, the temporary support is disassembled. Among them, the load-bearing frame 6 is used to adjust the installation height, and the sliding plate 3 is used to reduce friction and wear.
