Problems solved by technology

[0004] When two adjacent floor slabs or wall panels are spliced, steel bars are generally welded and then the exposed steel bars are grouted and sealed, so that the two adjacent floor slabs or wall panels are integrated. This type of splicing method needs to wait for the concrete grout solidified, and unable to quickly fasten two floor or wall panels

Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] combine Figure 1 to Figure 4 As shown, the adjustable automatic locking mechanism of the present invention is schematically shown, including a locking part 1 and a plugging part 2 .

[0027] Such as Figure 1 to Figure 3 , the locking part 1 includes a hollow first housing 11 and a lock body 12 that is movably arranged on the first housing 11, which enables the lock body 12 to move in the first housing 11, and the plug-in part 2 includes a hollow The second housing 21 and the plug connector 22 movably arranged on the second housing 21 , the plug connector 22 is in the shape of a plate, and the plug connector 22 can be extended or retracted from the second housing...

Abstract

The invention relates to the field of subway construction, in particular to an adjustable automatic locking mechanism. High-pressure cement slurry is injected into a cavity, a plug connector can be pushed to extend out of a second shell, a guide hole is formed in an inserting groove of a lock body, a locking pin is movably arranged in the guide hole in a penetrating mode, a locking member is located in the lock body, the locking member is movably connected with the lock body, the locking member prevents the locking pin from penetrating into the inserting groove under normal conditions, when the plug connector is inserted into the inserting groove, the plug connector pushes the locking member to recede the locking pin, and the locking pin penetrates into the inserting groove and is arrangedin a locking hole of the plug connector in a penetrating mode to automatically lock the plug connector and the lock body. According to the adjustable automatic locking mechanism, the automatic splicing of two adjacent prefabricated panels can be realized without manual operation so as to reduce the man-hours for splicing the prefabricated panels.

Description

technical field [0001] The invention relates to the field of subway construction, in particular to an adjustable automatic locking mechanism. Background technique [0002] Existing subway stations and underground diaphragm walls are constructed in the form of in-situ pouring, that is, concrete grout is poured to wrap the steel cage, and after the concrete is solidified, it is closely combined with the steel cage to form the floor, wall or underground diaphragm wall of the station. However, it is difficult to ensure the proportion of concrete for on-site pouring, and the environment of the pouring site is uncontrollable, and it is very easy for foreign matter to invade the uncured concrete, which leads to the failure of the station or underground diaphragm wall to meet the design specifications, leaving a problem for subsequent construction. Security risks. [0003] In order to ensure the quality of the building body and underground diaphragm wall of the station, and improve...
