External plug type assembly type station connecting device

Abstract

The invention relates to the technical field of constructional engineering, and discloses an external plug type assembly type station connecting device. An assembly type station comprises a pluralityof first components and second components and a connecting pipe main body. The connecting pipe main body comprises a first connecting end and a second connecting end. The first connecting end is connected with the first components through threads. The second connecting end is provided with connecting openings matched with the second components. The second components are provided with protruding parts. Cover plates are arranged at the bottoms of the protruding parts. The protruding parts are inserted into the connecting openings. The cover plates are arranged at the ends of the connecting openings. The connecting pipe main body is sequentially provided with a filling opening and an exhaust port. By the adoption of the technical scheme, the external plug type assembly type station connectingdevice is convenient to construct and install and high in strength and shock resistance.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an outer plug-type assembled station connection device. Background technique [0002] At present, the node processing methods of prefabricated stations mainly adopt node cast-in-place, tongue and groove connection, plug-in connection, corbel anchor bolt connection, bolt connection and so on. Among them, the joint cast-in-place connection adopts the way of cast-in-place concrete at the joint; the tongue-and-groove connection and the plug-in connection are mainly connected by making concave and convex tenons at both ends of the connector; the corbel anchor bolt connection and Bolt connection is mainly to connect the nodes by bolts and anchor bolts. [0003] The node connections of the prior art mainly rely on cast-in-place treatment at the nodes, such as node cast-in-place, tongue and groove connections, plug-in connections, and the like. Although prefabricated c...

Problems solved by technology

The above connection methods, except for the connection of prefabricated components, are poor in integrity except for the cast-in-place joints, and the joints are prone to water seepage, which cannot meet the underground waterproof requirements of subway stations

[0004] Moreover, the joints of the existing cast-in-place nodes are prone to the problem of mortar leakage, which affects the strength of the joints, resulting in insufficient strength of the prefabricated station
