Abstract

The invention provides a taper spring sleeve-clamping sleeve connecting and assembling device for prefabricated parts of an underground comprehensive pipe gallery, solving the problem that the space of the comprehensive pipe gallery is narrow, construction quality and construction efficiency are difficult to guarantee. A bottom plate (17), a top plate (15) and left and right wallboards (16) are connected to form the pipe gallery. The top plate and the bottom plate are of the same structure and symmetrical in the up-down direction. The top plate and the bottom plate are each formed by sequentially connecting a first prefabricated part, a second prefabricated part and third-n prefabricated part, wherein the structures of the third-(n-1) prefabricated parts are the same as the structure of the second prefabricated parts, and the n prefabricated part and the first prefabricated part are of the same structure and symmetrical in the left-right direction. The left wallboard and the right wallboard are each composed of n (n+1) prefabricated parts and n (n+2) prefabricated parts, wherein the n (n+1) prefabricated parts and the n (n+2) prefabricated parts are symmetrical. A steel bar (12) of the first prefabricated part (14) is fixedly connected with a first steel plate (5). A plurality of holes are formed in the first steel plate and connected with a taper spring sleeve (4) through nuts (6). A first center shaft (9) is arranged in the symmetry center of the first connecting surfaces of the first prefabricated part (14) and the second prefabricated part (13). The first prefabricated part and the second prefabricated part are in movable fit with a plurality of first and second pull rods (10 and 25). Hook grooves in one ends of the first and second pull rods are connected with the center shaft oppositely.

Description

Technical field: [0001] The invention is related to the building structure of the underground comprehensive utility gallery. Background technique: [0002] The construction of my country's underground comprehensive pipe gallery is a strategic measure to improve the comprehensive carrying capacity of the city and the quality of urbanization development, stimulate investment, and create a new driving force for economic development. The construction requirements are high, and the requirements for civil air defense and earthquake resistance must be met. Therefore, high technical requirements are put forward for the construction of comprehensive pipe gallery. The document of the State Council proposes to promote the standardization of the main structural components of the underground comprehensive pipe corridor, and actively promote the application of prefabricated assembly technology. The prefabricated integrated pipe gallery adopts factory-made components, which not only can ...
