Description

Vertical post-cast strip block structure

Technical Field

The utility model belongs to housing construction engineering construction field, concretely relates to vertical post-cast strip block structure.

Background

The post-cast strip is a concrete strip reserved at the corresponding position of a foundation slab, a wall and a beam according to the design or construction specification requirement for preventing harmful cracks possibly generated by uneven self shrinkage or uneven settlement of a reinforced concrete structure in the building construction.

The vertical post-cast strip, such as a post-cast strip of a basement, serves as an important part of the whole project construction, the conventional sealing method for sealing the vertical post-cast strip of the basement is to build brick walls on the outer side of the vertical post-cast strip, and the brick walls are easy to be mechanically damaged in the backfilling process due to low masonry strength of the brick walls, so that the problems of repair and the like occur.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: a vertical post-cast strip plugging structure is provided.

In order to solve the technical problem, the inventor reachs through practice and summary the utility model discloses a technical scheme, the utility model discloses a vertical post-cast strip block structure, including the shear force wall, including prefabricated apron, prefabricated apron includes recess and rings more than a set of, the recess is located terminal surface under the prefabricated apron, rings are pre-buried in prefabricated apron up end, and when adjacent prefabricated apron is assembled from top to bottom the recess is suitable for and holds rings.

Preferably, both ends of the side surface of the prefabricated cover plate further comprise connecting holes. The connecting hole is used for assisting in fixing the prefabricated cover plate and the shear wall.

Preferably, the connecting hole is a waist-shaped hole, a tapered hole or a countersunk hole. The shape of the connecting hole can be selected as required, so that the prefabricated cover plate and the shear wall can be fixed in an auxiliary mode.

In some embodiments, second grooves are reserved on both the upper end surface and the lower end surface of each prefabricated cover plate, and when adjacent prefabricated cover plates are combined up and down, the adjacent second grooves are combined to form a second connecting hole. The combined scheme is more beneficial to the processing of the prefabricated cover plate, and a through hole does not need to be formed in the prefabricated cover plate.

Preferably, the second connecting hole is a kidney-shaped hole, a tapered hole or a countersunk hole.

Preferably, the shear wall comprises a pre-buried water stop steel plate, the water stop steel plate is connected with a screw rod and a threaded sleeve, and the threaded sleeve is in a state of reserving a mounting bolt before the post-cast strip is blocked. The bolt connection stability is strong, and the connecting hole can be plugged after the mounting bolt is fixed according to the requirement in the later stage.

In some embodiments, the upper end face of the prefabricated cover plate comprises a matching groove or a matching protrusion, and the lower end face of the corresponding prefabricated cover plate comprises a matching protrusion or a matching groove. The scheme of matching the upper prefabricated cover plate and the lower prefabricated cover plate is favorable for better installation and combination.

Compared with the prior art, the utility model discloses can obtain following technological effect:

the other side of the shear wall can be constructed according to a conventional formwork erecting process, the scheme of prefabricating the cover plate ensures consistency, high wall strength and strong stability, and the construction speed is also obviously improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The application of the principles of the present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1: as shown in fig. 1-3, the vertical post-cast strip blocking structure comprises a shear wall 1 and a prefabricated cover plate 2, wherein the prefabricated cover plate comprises more than one group of grooves 203 and hanging rings 201, the grooves are located on the lower end face of the prefabricated cover plate, the hanging rings are embedded in the upper end face of the prefabricated cover plate, and the grooves are suitable for accommodating the hanging rings when adjacent prefabricated cover plates are combined up and down. The two ends of the side surface of the prefabricated cover plate also comprise connecting holes 202. The connecting hole is a waist-shaped hole, a tapered hole or a countersunk hole. The shear wall comprises a pre-buried water stop steel plate 3, a water stop steel plate connecting screw rod and a threaded sleeve, before the post-cast strip is plugged, the threaded sleeve 101 is in a state of reserving a mounting bolt 4, and the threaded sleeve 101 can be a conical threaded sleeve.

In some embodiments, the upper end surface of the prefabricated cover plate comprises a matching groove or a matching protrusion, and the lower end surface of the corresponding prefabricated cover plate comprises a matching protrusion or a matching groove. Not shown in the figures.

Example 2: as shown in fig. 4, different from embodiment 1, second grooves 204 are reserved on both the upper end surface and the lower end surface of the prefabricated cover plate, and when the adjacent prefabricated cover plates are combined up and down, the adjacent second grooves are combined to form a second connecting hole, which is only shown in the figure in a schematic manner, and specifically, the second connecting hole is a kidney-shaped hole, a tapered hole or a counter bore.
