Description

Non-return grouting sleeve

Technical Field

The utility model relates to a building construction device, in particular to a non-return grouting sleeve.

Background

The prior assembly type building is generally provided with a grouting sleeve in advance, and the grouting sleeve is sleeved on a reserved structural steel bar, and grouting slurry is poured into the grouting sleeve to realize the connection of the prefabricated members; the grouting sleeve is provided with a grouting opening and a grout outlet in advance on the prefabricated member, the grouting nozzle is inserted into the reserved grouting opening for grouting, and when the grout outlet overflows with grout, grouting is finished; then plugging the plug at the grout outlet, plugging the plug at the grout outlet fast after extracting the grout mouth of grout gun, at the in-process of extracting grout robbing because the plug inserts untimely causing the thick liquids to flow from the grout outlet for grout sleeve upper portion connection reinforcing bar grouting plumpness is not enough, and the grout is not closely knit, influences the connection quality of prefab. Therefore, it is necessary to design a non-return type grouting sleeve.

Disclosure of Invention

The utility model aims to solve the technical problem of providing a non-return grouting sleeve, and solves the problem that grouting fullness of the existing grouting sleeve is difficult to ensure.

The utility model provides a non-return grouting sleeve for solving the technical problems, which comprises a sleeve body, wherein a grouting pipe and a grout outlet pipe which are communicated with the sleeve body are arranged outside the sleeve body, the grouting pipe is arranged at the lower part of the outer wall of the sleeve body, and the grout outlet pipe is arranged at the upper part of the outer wall of the sleeve body; the end part of the grouting pipe, which is far away from the sleeve body, is provided with a grouting opening, and the end part of the grouting pipe, which is far away from the sleeve body, is provided with a grouting opening; the grouting pipe is provided with a check valve which is opened in one direction to the sleeve body.

Further, the grouting pipe is perpendicular to the sleeve body, and the grout outlet pipe is obliquely arranged to the top of the sleeve body.

Further, the grout outlet of the grout outlet pipe is higher than the top end of the sleeve body, so that grout entering from the grout outlet of the grout outlet pipe flows out from the grout outlet of the grout outlet pipe after filling the sleeve body.

Further, the check valve is arranged at the joint of the grouting pipe and the sleeve body.

Further, the sleeve body is in welded connection with the check valve, and the sleeve body is in welded connection with the slurry outlet pipe.

Further, the diameter of the grouting pipe is larger than that of the grout outlet pipe.

Compared with the prior art, the utility model has the following beneficial effects: according to the non-return grouting sleeve provided by the utility model, the one-way check valve is arranged at the grouting pipe of the sleeve body, so that the grouting plumpness is insufficient because the grouting is not timely blocked after the grouting is pulled out and robbed, and the grouting is not timely caused by the outflow of the grouting from the grouting port; the grout outlet is higher than the sleeve body, so that the grouting is full, the grout can overflow from the grout outlet only when the grout outlet is full, and meanwhile, a part of grout is reserved in the grout outlet pipe, so that the grout leakage can be timely supplemented, and the grouting is full.

Drawings

Fig. 1 is a cross-sectional view of a non-return type grouting sleeve in an embodiment of the present utility model.

In the figure:

1. a sleeve body; 2. a check valve; 3. grouting pipes; 4. a slurry outlet pipe; 5. a grouting port; 6. and a pulp outlet.

Detailed Description

The utility model is further described below with reference to the drawings and examples.

In the present utility model, the terms "upper", "lower", "top", "bottom", "inner", "outer", "middle", and the like indicate an azimuth or a positional relationship based on that shown in the drawings. These terms are only used to better describe the present utility model and its embodiments and are not intended to limit the scope of the indicated devices, elements or components to the particular orientations or to configure and operate in the particular orientations. Furthermore, the terms "mounted," "configured," "provided," "connected," and "sleeved" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; may be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements, or components. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Referring to fig. 1, the non-return grouting sleeve in the embodiment of the utility model comprises a sleeve body 1, wherein a grouting pipe 3 and a grout outlet pipe 4 which are communicated with the sleeve body 1 are arranged outside the sleeve body 1, the grouting pipe 3 is arranged at the lower part of the outer wall of the sleeve body 1, and the grout outlet pipe 4 is arranged at the upper part of the outer wall of the sleeve body 1; the end part of the grouting pipe 3, which is far away from the sleeve body 1, is provided with a grouting opening 5, and the end part of the grouting pipe 4, which is far away from the sleeve body 1, is provided with a grouting opening 6; the grouting pipe 3 is provided with a check valve 2 which is opened in one direction to the sleeve body 1.
