Problems solved by technology

[0003] Compared with the traditional horizontal support system made of concrete materials, the horizontal support system assembled on site by various types of steel (including I-beam, channel steel, square steel, etc.) has the advantages of fast construction speed and recyclable steel. and other advantages, but at the same time, it is inevitable that the integrity is poor, especially the corners of the ring beam cannot be effectively connected, and the uneven stress state of each point leads to instability of the horizontal support system structure and uncontrollable construction quality of on-site assembly, etc. shortcoming

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] see Figure 1 to Figure 4 , a prefabricated and assembled monolithic foundation pit horizontal support system, including a number of ring beam members 1 connected end to end to form a whole; The pieces 11 need to be stacked up and down and then fixed, so that the hinged pieces 11 of the adjacent ring beam members 1 can be inserted into each other; the middle section of the ring beam member 1 is respectively welded with two corbels 12 with different orientations and arranged obliquely; The planar end of the leg 12 facing away from the ring beam member 1 is welded with a corbel connection plate 13; two corbels 12 close to each other on the adjacent ring beam member 1 are connected by braces 2 to fix the adjacent ring beam member 1 .

[0031] Further, the four ring beam members 1 are connected end to end to form a rectangular integral ri...

Abstract

The invention relates to a prefabricated assembled integrated foundation pit horizontal supporting system and a construction method thereof. The horizontal supporting system comprises a plurality of ring beam components which are connected end to end to form a whole; hinge pieces is welded to the two ends of the ring beam components respectively, the hinge pieces of the adjacent ring beam components need to be stacked up and down and then are fixed; and the middle section of the ring beam components is welded with two brackets with different directions and obliquely arranged; bracket connecting plates are welded to the plane end of the brackets back-to-ring beam components; the two adjacent ring beam components are connected through the inclined struts, and then the adjacent ring beam components are fixed. A plurality of ring beam components are hoisted into a foundation pit on site and are hinged through a hinge joint in sequence, and finally the integrated foundation pit horizontal supporting system is formed together with the inclined struts, so that the quality and stability of the horizontal supporting system can be guaranteed.

Description

technical field [0001] The invention relates to a prefabricated and assembled integral foundation pit horizontal support system and a construction method thereof, belonging to the technical field of civil engineering. Background technique [0002] The foundation pit support system usually includes two parts: the vertical support system and the horizontal support system. The vertical support system is used to directly bear the horizontal earth pressure of the surrounding bottom layer. The common forms of the vertical support system include steel sheet piles, ground connection walls, cast-in-situ piles, etc.; the horizontal support system mainly supports the vertical support system. The common form of horizontal support system includes concrete (or section steel) ring beam, concrete (or section steel) cross brace, etc. [0003] Compared with the traditional horizontal support system made of concrete materials, the horizontal support system assembled on site by various types o...
