Description

Technical Field

[0001] The invention relates to the technical field of construction support frames, and in particular to a combined support frame for truss assembly. Background Art

[0002] Truss: A structure made of rods connected to each other at both ends with hinges. A truss is a plane or space structure composed of straight rods, generally with triangular units. Truss rods mainly bear axial tension or pressure, so as to make full use of the strength of the material. When the span is large, it can save materials, reduce deadweight and increase rigidity compared to solid beams.

[0003] That is, trusses are usually used in scenarios with large spans, and are generally used as supporting beams on factory roofs and stadium roofs. During the truss construction process, due to the large span, a support system needs to be built in advance. In traditional construction, scaffolding is usually built, and the scaffolding is generally built from the ground, that is, the height of the scaffolding is large; and trusses are often designed with multiple trusses. When each truss is constructed, the support system needs to be rebuilt, which is time-consuming and labor-intensive, and the construction period is long. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses a combined support frame for truss assembly, including a transfer beam, on which a plurality of groups of vertically built support units are fixedly connected, and an L-shaped support is fixedly connected to the upper end of the support unit. The height of the support unit is the height of the truss support, and the side profile of the L-shaped support is L-shaped. The L-shaped structure is arranged so that when the current truss construction is completed, it is convenient to detach the L-shaped support from one side of the truss.

[0005] Both ends of the transfer beam are provided with guide rails, and the end of the transfer beam slides / rolls on the guide rails. A hydraulic push-pull sliding device is provided on the guide rail, and one end of the hydraulic push-pull sliding device is fitted on the guide rail, and the other end is fitted on the transfer beam. During the truss construction and the pouring of the building wall, it is necessary to pre-embed steel bull legs on the building body, that is, the support members extending from the wall, and the guide rails are installed on the steel bull legs. Then, the support frame for truss construction is built from bottom to top. The guide rails and hydraulic push-pull sliding devices are provided here, so that after the current truss construction is completed, the transfer beam and the upper structure can be moved as a whole by the two, thereby moving the support frame without disassembly and then transferring to the new construction area for assembly, which greatly improves the construction efficiency.

[0006] Preferably, the transfer beam comprises two I-beams arranged side by side, and a connecting crossbar is fixedly connected between the two I-beams. The I-beams and the connecting crossbar constitute the main structure of the transfer beam, which is the main supporting structure.

[0007] Preferably, the ends of the two I-beams are fixedly connected to support rods, and rollers are provided on the support rods. The rollers are rollingly fitted on the upper ends of the guide rails, that is, the transfer beam is rollingly fitted on the guide rails through the rollers.

[0008] Preferably, the support unit includes four vertically arranged columns, and diagonal rods are fixedly connected between adjacent columns. The columns and the diagonal rods are the main structure of the support unit.

[0009] Preferably, the ends of the columns are fixedly connected with connecting plates, and the connecting plates are provided with through holes, and ribs are provided between the connecting plates and the columns. Adjacent support units are fixedly connected by connecting plates, and bolts are inserted into the through holes to achieve fixation. Similarly, the support units and the transfer beams and L-shaped supports are also fixedly connected by connecting plates with bolts, which has the advantage of being removable.

[0010] Preferably, a supplementary support is provided between the support unit and the L-shaped support. As the length of the truss increases, the design of the truss tends to be arc-shaped, and the supplementary support is used when the distance between the support unit and the truss is less than the support height of one support unit to meet the construction requirements, and the supplementary support is a rod with connecting plates at both ends.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. Equipped with transfer beams, guide rails, hydraulic jacking and sliding equipment, etc., after the current truss is built, the supporting frame can be moved as a whole to support the newly constructed truss without the need to build the supporting structure again, which greatly improves the construction speed.

[0013] 2. The present invention adopts a modular design, which has the advantage of being easy to disassemble, transport and reuse. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] Combination Figures 1 to 4 As shown, a combined support frame for truss assembly includes a transfer beam 1, on which are fixedly connected a plurality of groups of vertically constructed support units 2. According to the needs of truss support, a corresponding number of groups of support units 2 can be constructed, and the height of each group is constructed according to the needs of truss support height. An L-shaped support 6 is fixedly connected to the upper end of the support unit 2. The L-shaped bracket 6 is a component in direct contact with the truss and is arranged in an L shape. The purpose is that after the current truss is constructed, only the L-shaped bracket 6 can be removed and detached from between the support unit 2 and the truss.

[0023] Guide rails 3 are provided at both ends of the transfer beam 1. When the supporting frame is constructed, the guide rails 3 are pre-installed on the steel corbels preset on the building, and the steel corbels are set as far away from the ground as possible to achieve the use of the support unit 2, and the end of the transfer beam 1 slides / rolls on the guide rail 3. A hydraulic pushing and sliding device 4 is provided on the guide rail 3.
