Description

A new vertical joint connection structure of prefabricated wall panels

technical field

The utility model relates to the field of assembled buildings, in particular to a novel vertical seam connection structure of prefabricated wall panels.

Background technique

Prefabricated buildings refer to buildings assembled on site with prefabricated components. The advantage of this kind of building is that it is fast in construction, less restricted by climatic conditions, saves labor and can improve the quality of construction. Compared with traditional construction methods, prefabricated buildings have become more and more popular in the construction industry in recent years because of their time-saving and labor-saving features. Favor is a rapidly rising new conceptual architectural approach.

The connection technology of prefabricated building structures plays a vital role in the completion of this type of building. The connection technology is the key technology to ensure that the building has strong mechanical performance and seismic performance. The vertical joint connection in the traditional prefabricated shear wall structure is mainly to reserve steel bars in the prefabricated shear wall first, weld or overlap the reserved steel bars, and then form the formwork and post-cast concrete. This vertical joint connection technology There are the following problems: it is difficult to connect the steel bars, and the concrete needs to be poured with vertical formwork.

Therefore, it is necessary to design a convenient, fast and quality-controllable vertical joint connection method for prefabricated shear walls, which can not only ensure the construction quality, but also speed up the construction and meet the construction requirements of prefabricated buildings.

Contents of the invention

The purpose of this utility model is to solve the deficiencies in the prior art, to provide a new type of vertical joint connection structure of prefabricated wall panels, which can be completed by grouting in the grouting empty grooves formed after the assembly grooves and assembly plugs are matched and inserted. The fast and stable connection of the shear wall is easy to operate and saves time and effort.

In order to achieve the above purpose, the utility model is achieved through the following technical solutions: a new type of vertical joint connection structure of prefabricated wall panels, including a left prefabricated wall and a right prefabricated wall, The right side of the side prefabricated wall is provided with an assembly groove that penetrates up and down. On the left side of the right prefabricated wall, there is a position corresponding to the assembly groove that can match the assembly groove. For the inserted assembly plug, a front notch is recessed forward on the front side of the assembly groove, and a rear recess corresponding to the front notch is recessed backward on the front side of the assembly plug mouth.

Further, the front notch is completely spliced with the rear notch to form a closed grouting cavity.

Further, the front notch is any one of triangle, rectangle and semicircle, and the rear notch is any one of triangle, rectangle and semicircle.

The beneficial effects of the utility model are: the utility model discloses a new type of vertical seam connection structure of prefabricated wallboards, and the initial fixation of the two walls is carried out by matching and plugging the assembly grooves on the ends of the walls and the assembly plugs. , and then grout in the grouting cavity formed by the matching and splicing of the front notch and the rear notch to realize the tight and firm connection of the two walls. This structure can realize the quick connection of the prefabricated shear wall, and the operation process is convenient and quick The construction process is simplified, the construction difficulty is reduced, the component size accuracy is high, and it is easy to control. The integrity and mechanical performance of the assembled wall are superior, which greatly guarantees the construction quality.

Detailed ways

The structure, principle and working process of the present utility model will be further described below in conjunction with accompanying drawings 1-5 and specific embodiments, but the protection scope of the present utility model is not limited thereto.

It should be noted that the embodiments provided by the utility model are only for the effective description of the technical features of the utility model, and the positioning words such as the left side, the right side, the upper end, and the lower end are only for the purposes of the utility model embodiment. A better description should not be regarded as a limitation on the technical solution of the utility model.

A new vertical joint connection structure of prefabricated wall panels, comprising a left prefabricated wall 1 and a right prefabricated wall 2, and an upper and lower Through the assembly groove 3, on the left side of the right prefabricated wall 2, there is an assembly plug 4 that can be mated with the assembly groove 3 at a position corresponding to the assembly groove 3, so that A front notch 5 is recessed forward on the front side of the assembly groove 3, and a rear notch 6 corresponding to the front notch 5 is recessed rearward on the front side of the assembly plug 4. The front notch 5 is completely spliced with the rear notch 6 to form a closed grouting cavity 7 .

The front notch 5 is triangular, the rear notch 6 is triangular, and the grouting cavity 7 is rectangular. The shapes of the front notch 5 and the rear notch 6 are not specifically limited.
