Problems solved by technology

At present, the existing prefabricated finished supports and hangers are composed of C-shaped channel steel, embedded channel steel, supporting connectors, expansion anchor bolts, etc. The profiles are non-standard parts, and there is no national standard guidance. The mechanical parameters of the profiles of each manufacturer are mainly Refer to the test data, there is no unified standard, it is uneven, there are many types of brackets and specifications, and it is impossible to achieve a unified
There are many problems: For example, for different formwork systems of the main body, different construction methods (excavation, shield, pipe jacking, prefabrication, etc.) are required for the construction of pre-embedded channel steel; Poor control, poor verticality, low survival rate, poor fit, etc.

Embodiment 1

[0026] Embodiment 1: A pre-embedded component of a prefabricated support and hanger, including a pre-embedded channel steel 1, the back of the pre-embedded channel steel has an anchor bolt 2, and a T-shaped bolt 3 is installed at the notch of the pre-embedded channel steel 1 , and the bolt cap 31 of the T-bolt 3 is put into the notch of the embedded channel steel 1, the threaded end 32 of the T-bolt 3 faces outward, and also includes the embedded fixing part 4, the embedded fixing part 4 can be used in this device The grouting aluminum formwork is realized, and the installation hole matching the outer diameter of the T-bolt 3 is opened on the grouting aluminum formwork, and the threaded end 32 of the T-bolt 3 passes through the installation hole and is fixed by a nut 33; the embedded channel steel 1 After the T-bolt 3 is installed, the two ends are provided with sealing end covers, the hollow part of which is filled with foam 11, and the opening is sealed by a sealing film; the...

Embodiment 2

[0034] Embodiment 2: The structure and pre-embedded construction method in this embodiment are basically the same as those in Embodiment 1. The difference lies in that the clamping structure 5 is to alternately set obliques with different orientations on the contact surface between the pre-embedded channel steel and the bolt cap. Rack and rack, the contact surface of the bolt cap and the embedded channel steel is provided with a helical rack, and the bolt cap and the embedded channel steel alternately engage in the same direction. Different occlusal directions make the structure loosen in one direction and tighter in the other direction when the structure is subjected to external force, minimizing the impact of external force.

[0035] The adoption of this structure and construction method can overcome the problems of low standardization, poor quality control, poor verticality, low survival rate, and poor fit in the installation process of embedded parts in the prior art, and t...

Abstract

The invention discloses an assembled support post embedded component and a construction method thereof. The embedded component comprises an embedded steel channel and an embedded fixed part, wherein an anchor bolt is arranged on the back of the embedded steel channel; a T-shaped screw is arranged at the notch of the embedded steel channel; the cap of the T-shaped screw is arranged in the notch ofthe embedded steel channel, and the threaded end of the T-shaped screw is arranged outward; a mounting hole matched with the outer diameter of the T-shaped screw is formed in the embedded fixed part;and the threaded end of the T-shaped screw penetrates through the mounting hole and then is fixed by a nut. The assembled support post embedded component has the advantages of simple structure and convenience in assembly, and can effectively overcome the problems of low standard degree, poor quality control, poor perpendicularity, low success rate, poor compactness and the like.

Description

technical field [0001] The invention belongs to the technical field of infrastructure comprehensive pipe gallery installation, and in particular relates to a pre-embedded component of an assembled support and hanger and a pre-embedded installation construction method thereof. Background technique [0002] At present, urban comprehensive utility corridors are being implemented on a large scale across the country. Urban comprehensive utility corridors are municipal public tunnel spaces built underground in cities, and use them to lay municipal public pipelines such as electricity, communications, and water supply in one structure according to planning requirements. , implement unified planning, design, construction and management. The cables in the pipe gallery need to be installed on the side wall of the pipe gallery through the bracket system. From the perspective of technology and technology, the fabricated support and hanger has great advantages compared with the tradition...
