[0002] A frame structure is a structure composed of roof trusses, columns, and foundations. It has extremely high load-bearing capacity and durability, and this type of structure is widely used in public buildings and single-story industrial plants.

[0003] In practice, when setting up formwork for the frame beam between two sets of corbel-shaped concrete columns, the upper part of the corbel-shaped concrete columns is large, and the external scaffolding for installing the frame beam is heavy. It is necessary to erect a full-span ground scaffold to meet the load-bearing requirements, which leads to the blockage of the material transportation channel at the bottom. If the ground scaffold is canceled and the traditional through-bar structure is used directly, it cannot meet the size and strength requirements. Summary of the Invention

[0004] The purpose of this utility model is to provide an aerial formwork support device for frame beams, which solves the problem mentioned in the background art that the traditional through-bar cannot meet the size and strength requirements.

[0005] To achieve the above objectives, this utility model is implemented through the following solution: An aerial formwork support device for a truss beam is installed on a concrete column and includes connecting components and a frame structure. The frame structure includes supporting components and protective components. The connecting components are installed on the concrete column, the supporting components are installed on the concrete column through the connecting components, and the protective components are installed on the supporting components and erected between two adjacent sets of concrete columns. The supporting components are arranged in pairs, and the pairs of supporting components are symmetrically arranged on both sides of the concrete column through the connecting components.

[0006] Furthermore, the support assembly includes a support frame and a sand box. The support frame is connected to the concrete column via a connecting assembly, the sand box is disposed on the top of the support frame, and the protective assembly is disposed on the support frame via the sand box.

[0007] Furthermore, the protective assembly includes a connecting frame, a protective frame, and a retaining frame. The connecting frames are arranged in pairs on both sides of the concrete column. Each connecting frame is horizontally arranged between two adjacent concrete columns and located on the same side of the two concrete columns. The ends of the connecting frames are arranged on the sand box. The protective frames are arranged on the paired connecting frames. The fixing plates are arranged on the protective frames and located on both sides of the protective frames. The retaining frames are vertically arranged on the side of the protective frames.

[0008] Furthermore, the connecting assembly includes a through rod and bolts. The through rod is horizontally disposed in the concrete column, with both ends extending out of the concrete column. The support frame is fixedly connected to the ends of the through rod by bolts.

[0009] Furthermore, a level is installed on the connecting frame.

[0010] Furthermore, the support frame is a triangular support frame, and multiple sets of connecting components are provided, with the multiple sets of connecting components arranged at intervals along the vertical axis of the support frame.

[0011] Furthermore, the connecting frame is an I-beam, and the protective frame is composed of multiple sets of channel steel, which are evenly spaced.

[0012] Furthermore, a pressure plate is fitted onto the through rod, and the pressure plate is positioned between the bolt and the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model solves the problem that traditional through-bars cannot meet the size and strength requirements of formwork for frame beams by setting up connecting components and frame structure. It not only provides sufficient size and strength, but also achieves the aesthetics of the outside of the concrete column. Furthermore, by setting up a level, it enables the determination of the angle of the front and rear ends of the formwork. Attached Figure Description

The connecting component 1 is set on the concrete column 5 and includes a through rod 101 and a bolt 102. The through rod 101 is horizontally inserted into the concrete column 5, with both ends extending out of the concrete column 5, and the ends are fixed with bolts 102.

[0020] The support components 2 are arranged in pairs, and the pairs of support components 2 are symmetrically arranged on both sides of the concrete column 5 through connecting components 1. The support components 2 include support frames 201 and sand boxes 202. The support frame 201 is a triangular support frame. The vertical rod of the support frame 201 is fixedly connected to the end of the mandrel 101 by bolts 102, and then fixed to the concrete column 5. A pressure plate 103 is sleeved on the mandrel 101 and is arranged between the bolts 102 and the support frame 201. Multiple sets of connecting components 1 are arranged at intervals along the support frame 201. This arrangement can meet the adjustment of the formwork height of different frame beams. The sand box 202 is fixedly arranged on the top of the support frame 201. The simultaneous arrangement of triangular support frames on both sides of the concrete column 5 can effectively distribute the weight and pressure on the top of the concrete column 5 and provide sufficient size and strength for the top of the concrete column 5, thereby giving the top of the concrete column 5 better stability.

The connecting frame 301 is an I-beam and is horizontally welded to the same side of the two concrete columns 5, with its two ends respectively connected to the sand box 202 on the same side of the two concrete columns 5. The protective frame 302 is welded to the paired connecting frames 301 and is composed of multiple sets of channel steel. The multiple sets of channel steel are evenly distributed to provide a support platform for the top of the concrete columns 5, on which wooden boards or other platform boards can be laid. The retaining frame 303 is vertically welded to both sides of the protective frame 302. The protective frame 302 and the retaining frame 303 are connected by a fixing plate, which is 1200mm high.

[0022] In order to determine the angle of the front and rear ends of the formwork, an infrared level 4 is installed on the side of the connecting frame 301.

[0023] Working principle: During use, support frames 201 are installed at the front and rear ends of two sets of concrete columns 5 respectively. The support frames 201 are connected to the concrete columns 5 by a mandrel 101 inserted through the concrete columns 5, and the support frames 201 are fixed to the concrete columns 5 by bolts 102. A sand box 202 is installed on the top of each support frame 201, and a connecting frame 301 is welded to the sand box 202 on the same side of the two sets of concrete columns 5. A protective frame 302 is welded to the top of the connecting frame 301, and a protective frame 303 is installed on both sides of the protective frame 302. Finally, a platform board is laid on the protective frame 302 to complete the formwork.
