Set horizontal supports diagonally in each word structure; set diagonal braces in the vertical plane formed by beams and columns.

The horizontal beams are arranged in layers at different heights, and the horizontal beams on each floor are arranged in the same manner.

The support is composed of square steel plates corresponding to the number of columns one by one, the square steel plates are fixed to the building structure by bolts, and the lower ends of the columns are welded to the upper surface of the square steel plates.

The support body is provided with a vertical ladder as a channel connecting the ground and the operating platform.

A protective enclosure of a certain height is provided around the operating platform.

Compared with the prior art, the utility model has the following beneficial effects:

1. The support platform is based on the internal structure of the venue, and the height is set according to the elevation of different foundation positions to ensure that the upper ends of each platform are on the same elevation, which solves the problem of the strength and flatness of the support platform on the site, and can be applied to various Assembly of trusses with large spans and large sections.

2. The operating platform on the support platform is located under the top, and there is a working space between the top and the top, which is convenient for operators to operate, avoids the back and forth turning of components, saves manpower and material resources, and improves construction efficiency.

3. The platform is built inside the stadium. After the trusses are assembled, they can be lifted and hoisted, which reduces the multiple transfers of the trusses, reduces deformation, and reduces the single lifting height of the trusses. It improves efficiency and ensures construction safety.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Referring to Fig. 1, it can be seen from the figure that the large-span and large-section truss span assembly support platform of the present invention includes a support body and a support 1; the support body is composed of two rows of columns 2 and several horizontal beams 3, each Rows of columns 2 are 2-4, and the actual design is 3, and all horizontal beams 3 horizontally connect the columns 2 into one to form a plurality of word structures connected together. The support 1 is fixedly installed on the building structure (concrete), and the lower end of the column 2 is fixed on the support 1. Two horizontal top beams 4 are arranged on the top of the support body, and the two top beams 4 are correspondingly connected with the upper ends of the two rows of columns 2, and the two top beams form a truss platform supporting the truss. Two corresponding horizontal platform beams 5 are arranged under the two top beams 4, and the two platform beams 5 are correspondingly connected with two rows of columns 2; the two ends of the top beam 4 and the platform beam 5 cantilever a certain distance outward relative to the support body.

In order to facilitate workers' work, horizontal supports are arranged diagonally in the plane formed by the platform beams and the connection with the columns. The platform formed by the platform beams and horizontal supports is covered with bamboo springboards to form an operation platform, and a certain height of protective fence is set around the operation platform. , which is not only convenient for construction, but also can ensure the construction safety of operators. A working space is formed between the operating platform and the top beam, and workers can perform welding operations on all sides of the components without turning over large components, which is convenient and effective.

Horizontal supports 6 are arranged diagonally in each word-shaped structure; at the same time, diagonal braces 7 are arranged in the vertical plane formed by the horizontal beam 3 and the column 2 . Wherein, the horizontal beams 3 are arranged in layers at different heights, and the horizontal beams 3 on each layer are arranged in the same way. Through the above connection structure, the strength of the support body can be further enhanced, so that it can be connected into a whole stress-bearing frame body.

The support 1 is composed of square steel plates corresponding to the number of columns 2 one by one. Connection holes arranged vertically and horizontally are arranged on the steel plates. The square steel plates are fixed to the building structure through bolts and connection holes. The lower ends of the columns are welded to the upper surface of the square steel plates.

For the convenience of going up and down, the support body is provided with a vertical ladder 8, and the ladder 8 is made of round steel as a passage connecting the ground and the operating platform.

The columns are steel pipes, the horizontal beams and diagonal braces are angle steels, and the platform beams and top beams are square steels. The platform is a steel frame structure, and the parts are connected by welding.

When the truss is assembled, the number of the support platforms can be determined according to the number of truss segments, and the distance between each support platform can be determined by the length of the truss segments. It is suitable for the assembly of various types of segmented trusses, and is also suitable for different spans. Venue installation needs. Figure 2 and Figure 3 are the assembly effect diagrams of the support platform and the truss. In the figure, the truss is divided into three sections, so four sets of support platforms are required. Figure 2 reflects the assembly effect of the bracket platform and the truss in the building venue.

The height of each support platform is determined according to the elevation of the installation location inside the venue, so as to ensure that the top elevation of each platform is consistent, and the flexible height control increases the applicability of the platform.
