Embodiment Construction

[0017] The use case of the present invention is described below in conjunction with accompanying drawing: this case is carried out under the premise of the present invention, has provided detailed embodiment and concrete operation process, but protection scope of the present invention is not limited to following case.

[0018] Such as figure 1 , As shown in 2, a spliced ​​steel purlin includes a steel purlin 1, a purlin support 5, a purlin connecting member 2 and a supporting end hanging plate 6. The section steel purlin 1 is installed on the enclosure structure 7 through the purlin support 5, the section steel purlin 1 has a reserved position for installing the purlin connecting member 2, and several sections are connected by bolts and purlin connecting member 2. The profiled steel purlins 1 are spliced ​​together to form a whole.

[0019] Sectional steel purlin 1 is mainly composed of section steel, reinforcing ribs and reserved installation positions for connecting compone...

Abstract

The invention relates to a splicing type steel enclosing purlin, comprising a profile steel enclosing purlin, enclosing purlin supports, enclosing purlin connecting components and supporting end hanging plates, the profile steel enclosing purlin is installed on an enclosing structure through the enclosing purlin supports, reserved positions for installing the enclosing purlin connecting componentsare reserved on the profile steel enclosing purlin, and a plurality of profile steel enclosing purlins are spliced together to form a whole through bolts and the enclosing purlin connecting components. Mounting bolt holes matched with the enclosing purlin connecting components are formed in the profile steel enclosing purlin, the profile steel enclosing purlin connecting components are mounted atthe reserved positions of the profile steel enclosing purlin and fixedly connected with the profile steel enclosing purlin through fastening bolts, and the mounted enclosing purlin connecting components control adjusting plates to be tightly attached to profile steel enclosing purlin webs through jacks to form joint stress. The splicing type steel enclosing purlin is simple and convenient to install, greatly saves the burdening, welding and installing workloads of the steel purlins, and can solve the problems that the splicing and welding workloads of traditional steel purlins are large, theconstruction efficiency is low, and the dismantling loss is large.

Description

technical field [0001] The invention relates to a steel-supported purlin system, in particular to a spliced ​​steel purlin suitable for the steel-supported purlin support system. Background technique [0002] With the acceleration of urban development, urban construction has become increasingly complex, and the development of underground space has led to rapid development of deep foundation pit engineering. In deep foundation pit engineering, there is a steel support support system. In order to ensure the balance of force on the support system, a steel purlin system surrounding the foundation pit is provided at the end of the support. In actual construction, this traditional steel purlin system is proportioned according to the actual characteristics of the project. During installation, all welding connections are used. The welding workload is heavy and the construction time is long. The welded parts of the steel purlin system are damaged during the dismantling process. , an...
