Prefabricated steel structure supporting platform and installation and disassembly method thereof

Abstract

The invention discloses a prefabricated steel structure supporting platform and an installation and disassembly method thereof. The supporting platform comprises multiple rows of buttresses arranged at intervals, the space between every two adjacent rows of the buttresses is consistent, each buttress is detachably provided with multiple steel supporting cylinders connected with one another, and multiple connecting pieces are connected between every two adjacent rows of the steel supporting cylinders; each row of the steel supporting cylinder located at the top end is detachably provided with alongitudinal joist steel crossing all the steel supporting cylinders in the row; all the longitudinal joist steels form a lower supporting layer, the lower supporting layer is provided with multipletransverse joist steels crossing multiple rows of the longitudinal joist steels and detachably connected with the longitudinal joist steels, all the transverse joist steels form an upper supporting layer, and the upper supporting layer is fully paved with a steel structure or a plank platform. The prefabricated steel structure supporting platform and the installation and disassembly method thereofhave the advantages that the safety is high, the installation and disassembly are convenient, and the construction is convenient.

Description

technical field [0001] The invention relates to a bridge support platform, in particular to an assembled steel structure support platform and its installation and disassembly methods. Background technique [0002] In the construction of bridges, bridge construction methods are mainly divided into two types of construction methods: prefabricated erection construction and in-situ cast-in-place construction. Among them, in-situ cast-in-place construction mainly includes the following types: (1), cast-in-place construction of mobile formwork; (2), cast-in-place construction method of full hall support bracket; (3), steel pipe pile support + Bailey frame + bowl Cast-in-place construction of fasteners. Among the above three construction methods, the mobile formwork cast-in-place construction has a high degree of mechanization and does not need to consider the ground conditions, but it is only suitable for specific bridge-type cast-in-place construction, but there are problems suc...

Problems solved by technology

Among the above three construction methods, the mobile formwork cast-in-place construction has a high degree of mechanization and does not need to consider the ground conditions, but it is only suitable for specific bridge-type cast-in-place construction, but there are problems such as difficult assembly and inconvenient transportation of large components; Although it is suitable for all types of bridges, the erection of the support is labor-intensive and time-consuming. Although the upper load has been shared by the support poles, the local area stress under the poles still cannot be effectively dispersed, so the bearing capacity of the foundation The requirements are still a bit high, and different foundation treatment schemes are required for different geological conditions; while the cast-in-place construction of steel pipe pile supports + Bailey frames + bowl fasteners requires a large amount of materials, not only the cost is high, but also the construction safety Poor and difficult, it is generally difficult to meet the acceptance requirements of technical quality effects, and due to the limitations of the construction site, it is not conducive to the stacking and use of a large number of sporadic materials, which greatly increases the construction cost
