Embodiment Construction

[0011] The present invention forms an adjustable integral cross joint by splicing the cross joint and the adjustment section, and can realize the adjustable integral cross joint node supported by the steel pipe. In conjunction with the accompanying drawings, the specific description is as follows:

[0012] like figure 1 As shown, the longitudinal and transverse steel pipe supports 1 are respectively connected to the two ends of the cross joints 2 , and the adjustment section 3 connects two adjacent cross joints 2 . By setting the adjustment section 3 between the cross joints 2, the distance between the steel pipe supports 1 can be adjusted arbitrarily. The number of regulating segments in the figure is one segment, or multiple segments can be spliced ​​with each other. The figure is only an illustration, and the specific number can be determined according to the actual requirements of the project. figure 2 is a schematic diagram of the cross joint 2; image 3 A schematic d...

Abstract

The invention belongs to the technical field of foundation pit protect and relates to a bidirectional adjustable integration cruciform-joint joints for steel pipe bracing. The technical scheme is that the bidirectional adjustable integrating cruciform-joint joint used for steel pipe bracing uses the splicing connection of a cruciform joint and an adjusting segment to form an adjustable integration cruciform joint which is connected with a longitudinal steel pipe bracing and a transverse steel pipe bracing. The adjusting segment can be the splicing connection of two and more adjusting segments or one is enough. The invention provides the bidirectional adjustable integration cruciform-joint joints for steel pipe bracing. The bidirectional adjustable integration cruciform-joint joints for steel pipe bracing can be used for the adjustment of the horizontal spacing of the steel pipe bracing system.

Description

technical field [0001] The invention belongs to the field of foundation pit support of fixed buildings, and relates to a structural device for bidirectionally adjustable integral cross joints supported by steel pipes, which can be widely used in foundation pit support projects using horizontal steel pipe support systems. Background technique [0002] With the acceleration of my country's urbanization process and the development of underground space, the area of ​​underground buildings is also increasing, the depth of excavation is deepening, and the support methods of foundation pits are constantly being innovated. The support material that is convenient and does not generate construction waste is being more and more used in foundation pit engineering. Steel pipe supports in large-area foundation pits are generally arranged in a cross-orthogonal arrangement or a double cross-arrangement arrangement, and supporting columns are arranged vertically. Using conventional integral ...
