DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1 and Figure 2 As shown, a temporary support frame includes: a base 1 and various sheet components on the base 1 are spliced ​​together.

[0038] like Figure 3 and Figure 4 As shown, a plurality of first sheets 2 and a plurality of second sheets 3 are arranged on the base 1, and the first sheet 2 comprises: a first vertical rod 203, the two ends of the first vertical rod 203 are respectively connected to a first horizontal rod 202 through a first flange 201, one end of two of the first horizontal rods 202 are respectively connected to a first oblique rod 204, and the other end of the first oblique rod 204 is connected to the first flange 201. The second sheet 3 comprises: a second vertical rod 303, the two ends of the second vertical rod 303 are connected to two second horizontal rods 302 through a second flange 301, the two second horizontal rods 302 connected to the same second flange 301 are coaxially arranged, one end of four of the second horizontal rods 302 are respectively connected to the second oblique rods, and the other end of the second oblique rod 304 is connected to the second flange 301. The sheet assembly is formed by splicing a plurality of first sheets 2 and second sheets 3, and the plurality of sheet assemblies are sequentially spliced ​​from bottom to top to form a support frame. Since the overall weight of the first sheet 2 and the second sheet 3 is relatively light, on-site workers can manually carry and install the first sheet 2 and the second sheet 3 without the need for other mechanical assistance, thereby effectively reducing installation costs.

[0039] It should be noted that the first vertical rod 203 and the second vertical rod 303 have the same structure, the first horizontal rod 202 and the second horizontal rod 302 have the same structure, the first flange 201 and the second flange 301 have the same structure, and the main difference between the first sheet 2 and the second sheet 3 lies in the assembly method and the number of required parts.

[0040] Among them, the sheet components can be assembled into three structural forms: a mouth shape, a sun shape, and a field shape. According to the on-site construction requirements, the shape of the assembled sheet components can be freely selected to install the support frame as a whole to a specified height and a specified overall structural state. It should be noted that the mouth-shaped sheet component is composed of four first sheets 2 spliced ​​together, and the sun-shaped sheet component and the field-shaped sheet component are both composed of a first sheet 2 and a second sheet 3 spliced ​​together. Two sheet components at the same height and adjacent to each other are connected by auxiliary ribs on the first flange 201 and the second flange 301.

[0041] When assembling the support frame, according to the on-site installation requirements, the first sheet 2, the second sheet 3, the first flange 201 and the second flange 301 are respectively assembled into sheet components in the shape of a square, a sun and a field, to form a support frame with various structural forms to adapt to different heights and tonnages, thereby adapting to different installation requirements and improving the scope of application. The sheet component at the bottom is connected to the base 1 through a bolt rod, and then the sheet components are hoisted in sequence until the required number of sheet components are installed. The bolts at the connection between the first flange 201 and the first flange 201 and the connection between the second flange 301 and the second flange 301 are aligned and tightened. Finally, the top seat 6 and the related unloading device are installed. The support frame is installed as a whole. Only the first sheet 2 and the second sheet 3 are assembled to form the support frame, which reduces the complexity of on-site assembly, reduces the workload during assembly, and thus improves construction efficiency.

[0042] like Figure 5 and Figure 6 As shown, when the sheet assembly is in the shape of a square, that is, the top view of the sheet assembly is in the shape of a square, the sheet assembly in the shape of a square is composed of four first sheets 2 spliced ​​together, and two first sheets 2 adjacent to each other are connected end to end to form a sheet assembly in the shape of a square. When assembling the sheet assembly in the shape of a square, a first sheet 2 is placed flat on the ground, and then two first sheets 2 are installed in a direction perpendicular to it, and finally a first sheet 2 is installed on the top to form a sheet assembly in the shape of a square. After tightening each first sheet 2 by bolts, the sheet assembly in the shape of a square is erected vertically for subsequent assembly.

[0043] like Figure 7 and Figure 8As shown, when the sheet component is in the shape of a Chinese character 'Ri' (i.e., the top view of the sheet component is in the shape of a Chinese character 'Ri'), the sheet component in the shape of a Chinese character 'Ri' is composed of one second sheet 3 and five first sheets 2 spliced together. When assembling the sheet component in the shape of a Chinese character 'Ri', place one second sheet 3 flat on the ground, then install three first sheets 2 in a direction perpendicular to it, and finally install two first sheets 2 on the top to form a sheet component in the shape of a Chinese character 'Ri'. After fastening each first sheet 2 and the second sheet 3 with bolts, stand this sheet component in the shape of a Chinese character 'Ri' vertically for subsequent assembly.

[0044] As Fig. 9 and Fig.10 shown, when the sheet component is in the shape of a Chinese character 'Tian' (i.e., the top view of the sheet component is in the shape of a Chinese character 'Tian'), the sheet component in the shape of a Chinese character 'Tian' is composed of three second sheets 3 and six first sheets 2 spliced together. When assembling the sheet component in the shape of a Chinese character 'Tian', place the first second sheet 3 upright on the ground, then symmetrically install two first sheets 2 and two second sheets 3 in a direction perpendicular to it. The two first sheets 2 are symmetrically installed in the middle part of the first second sheet 3, and the two second sheets 3 are symmetrically installed at both ends of the first second sheet 3. Finally, install four first sheets 2, and the four first sheets 2 are installed upright to form a sheet component in the shape of a Chinese character 'Tian'. After fastening each first sheet 2 and the second sheet 3 with bolts, stand this sheet component in the shape of a Chinese character 'Tian' vertically for subsequent assembly.

[0045] As Figure 3 and Fig.12 shown, the first flange 201 is symmetrically arranged at both ends of the first vertical rod 203, and the second flange 301 is symmetrically arranged at both ends of the second vertical rod 303. Four connecting holes 5 are arranged in an array on the bottom surface of the first flange 201 and the bottom surface of the second flange 301. When assembling the support frame, the first flanges 201 of the upper and lower two sheet components and the first flanges 201, and the second flanges 301 and the second flanges 301 are connected to each other through four bolt rods, and there is no need to use additional connecting parts to connect each sheet component, effectively improving the overall installation efficiency of the support frame.

[0046] Preferably, the first vertical rod 203 and the first flange 201 are integrally arranged, and the second vertical rod 303 and the second flange 301 are also integrally arranged. The first flange 201 and the first vertical rod 203 are connected together by welding, and the second flange 301 and the second vertical rod 303 are also connected together by welding. There is no need to disassemble and assemble the first sheet 2 and the second sheet 3 on site later, and the overall structural stability of the first sheet 2 and the second sheet 3 connected by welding is better. Of course, it is also possible to choose to connect them together by bolt connection, and the connection form is not limited.

[0047] Four auxiliary ribs 4 are arranged on one side of the first flange 201 and one side of the second flange 301, and the angle between two adjacent auxiliary ribs 4 is 90°, that is, two adjacent auxiliary ribs 4 are arranged perpendicular to each other. On the one hand, the arrangement of the auxiliary ribs 4 serves to enhance the structural strength of the first flange 201 and the second flange 301. On the other hand, the arrangement of the auxiliary ribs 4 is used to connect the first diagonal rod 204 and the first horizontal rod 202, the second diagonal rod 304 and the second horizontal rod 302, wherein the first diagonal rod 204 and the second diagonal rod 304 are cross-arranged, which can further enhance the stability of the sheet assembly, thereby improving the structural strength of the overall support frame and enhancing the load-bearing capacity.

[0048] Among them, one end of the first horizontal rod 202 and one end of the second horizontal rod 302 are both connected to the auxiliary rib 4. Preferably, in the first sheet 2, the first horizontal rod 202 and the auxiliary rib 4 on the first flange 201 are connected together by welding, and the first oblique rod 204 and the auxiliary rib 4 on the first flange 201 are also connected together by welding. In the second sheet 3, the second horizontal rod 302 and the auxiliary rib 4 on the second flange 301 are connected together by welding, and the second oblique rod 304 and the auxiliary rib 4 on the second flange 301 are also connected together by welding. That is, in the prefabrication stage of the factory, the first sheet 2 and the second sheet 3 have been assembled and formed. When transporting, the first sheet 2 and the second sheet 3 are staggered left and right, and the first sheet 2 and the second sheet 3 are staggered left and right. Since the first sheet 2 and the second sheet 3 are in sheet form as a whole, it is more convenient to stack, the risk of scattering is small, and it is convenient for the staff to load and unload, which improves the convenience during transportation and reduces the transportation cost.

[0049] It should be noted that if Fig.11 As shown, in the first sheet, three of the four auxiliary ribs 4 on the first flange 201 are provided with two second docking holes 10. The second docking holes 10 can also be used to pass a cable wind rope, which can further fix the support frame and improve the stability of the support frame. At the same time, two first docking holes 9 are provided on the surface of the connecting plate 8, and each first docking hole 9 is connected to the second docking hole 10 by a bolt rod.

[0050] like Fig.13 As shown, in the second sheet 3, two of the auxiliary ribs 4 in the second flange 301 are no longer provided with the second docking holes 10, and the two auxiliary ribs 4 are directly connected to the second horizontal rod 302 and the second oblique rod 304 by welding, while the other two auxiliary ribs 4 perpendicular to the above-mentioned auxiliary ribs 4 are provided with second docking holes 10 for connecting other sheets or wind ropes.

[0051] In addition, both the first sheet body 2 and the second sheet body 3 are provided with two specifications. The height of the first sheet body 2 of the first specification is less than the height of the first sheet body 2 of the second specification. The height of the second sheet body 3 of the first specification is less than the height of the second sheet body 3 of the second specification. When assembling the support frame, the first sheet body 2 and the second sheet body 3 of the first specification are preferably selected for assembly to form the support frame, and the first sheet body 2 and the second sheet body 3 of the second specification are selected for assembly to form the adjustment section 7. The adjustment section 7 is installed on the top of the support frame to assist in adjusting the overall height of the support frame so that it can accurately adapt to the on-site construction environment.

[0052] Preferably, in the factory prefabrication stage, the first horizontal rod 202, the first diagonal rod 204, the first vertical rod 203, the first flange 201 and the auxiliary rib plate 4 are connected by welding to form the first sheet body 2. The second horizontal rod 302, the second diagonal rod 304, the second vertical rod 303, the second flange 301 and the auxiliary rib plate 4 are connected by welding to form the second sheet body 3. The first sheet body 2 and the second sheet body 3 are directly assembled on site, and are assembled into a sheet body assembly in the shape of a square, a sheet body assembly in the shape of a Chinese character 'Ri', and a sheet body assembly in the shape of a Chinese character 'Tian' according to requirements. No complex connecting pieces and rods are required, effectively reducing the complexity of on-site assembly, reducing the workload, and thus improving the installation efficiency.

[0053] When the utility model is in use, it includes the following steps: After transporting the prefabricated first sheet body 2 and second sheet body 3 from the factory to the construction site, according to the on-site installation requirements, the first sheet body 2 and the second sheet body 3 are cooperatively assembled into a sheet body assembly in the shape of a square, a sheet body assembly in the shape of a Chinese character 'Ri', and a sheet body assembly in the shape of a Chinese character 'Tian' respectively. The sheet body assembly at the bottommost part is connected to the base 1 through bolt rods, and then each sheet body assembly is hoisted in sequence until the required number of sheet body assemblies are installed. The bolts at the connection between the first flange 201 and the first flange 201 and at the connection between the second flange 301 and the second flange 301 are aligned and tightened. The adjustment section 7 is fabricated and installed as the topmost sheet body assembly. Finally, the top seat 6 and related unloading devices are installed above the topmost sheet body assembly, and all connection points are inspected to complete the overall installation of the support frame.

[0054] In summary, by splicing the first sheet body 2 and the second sheet body 3 to form various structural forms such as a sheet body assembly in the shape of a square, a sheet body assembly in the shape of a Chinese character 'Ri', and a sheet body assembly in the shape of a Chinese character 'Tian', it can directly adapt to different installation requirements, expand the applicable range, and make the overall support frame more flexible. Moreover, only the first sheet body 2 and the second sheet body 3, two standard parts, are assembled to form the support frame, reducing the complexity of on-site assembly, reducing the workload during assembly, and effectively improving the construction efficiency.

[0055] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0056] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
