Description

Technical Field

[0001] The utility model relates to the technical field of cabinet bottom plate pouring, in particular to a prefabricated overhead bottom plate structure for cabinets. Background Technique

[0002] In-situ casting means that when constructing a building structure, a hollow formwork is assembled according to the shape and size of the building structure, and the formwork is fixed by positioning means, and then concrete is poured into the formwork cavity. After the poured concrete solidifies and forms, the formwork is removed.

[0003] Generally, the cabinet bottom plate needs to prevent water from splashing in. The cabinet bottom plate is designed to be 10 cm higher than the ground. If the cabinet bottom plate is directly made from the height of the building structure bottom plate, plus the height of tiling, it is a total of 15 cm. The existing process for making the cabinet bottom plate is to use the overall in-situ casting method. The conventional method is to support the formwork by 15 cm and pour all the concrete. This construction method will not only cause excessive local load and waste of concrete, but also has many construction processes, slow operation, involves many types of work, and has a high cost problem.

[0004] Therefore, how to reduce the local load of the building structure bottom plate on the premise of simplifying the cabinet bottom plate construction process, saving labor and materials is a technical problem to be solved urgently.

[0005] It should be particularly noted that the above technical information is only intended to deepen the understanding of the overall background technology of the present utility model, and should not be regarded as an admission or any form of suggestion that the above technical information constitutes the prior art known to those skilled in the art. Content of the Utility Model

[0006] In view of the deficiencies in the above background technology, the present utility model proposes a prefabricated overhead bottom plate structure for cabinets, which solves the technical problems of the existing cabinet bottom plate construction process being complex, wasting labor and materials, and having excessive local load.

[0007] The technical solution of this application is as follows:

[0008] A prefabricated overhead bottom plate structure for a cabinet, comprising a front side part, a left side part, a right side part and a top side part integrally cast. The front side part, the left side part and the right side part enclose a closed concave structure body, and the top side part is connected above the concave structure body. Both the left side part and the right side part are provided with prefabricated grooves opening outwards. This technical solution provides an integral prefabricated structure for the cabinet bottom plate, mainly composed of a front side part, a left side part, a right side part and a top side part, which is not only convenient for batch prefabrication and on-site installation, but also the lower hollow structure can avoid the problem of excessive local load. At the same time, the front side part is an integral structure, which can effectively replace the waterproof sill and avoid the in-situ casting of the waterproof sill during on-site construction. At the same time, the structural design of the prefabricated groove will neither increase the difficulty of prefabrication, but also enhance the connection structure strength when assembling each prefabricated monomer. When assembling the prefabricated monomers, they can be directly made into a continuous cabinet bottom plate structure through local in-situ casting.

[0009] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead bottom plate structure for the cabinet, the prefabricated grooves provided on the left side part and the prefabricated grooves provided on the right side part correspond to each other left and right. When assembling the prefabricated overhead bottom plate structure for the cabinet, adjacent prefabricated overhead bottom plate structures for the cabinet can be connected more firmly and reliably through the corresponding prefabricated grooves. At the same time, it is also convenient for the prefabrication of the prefabricated overhead bottom plate structure for the cabinet, without the need to construct the prefabricated formwork into an asymmetric structure according to the different positions of the prefabricated grooves on both sides, thus avoiding the direction selection of the prefabricated formwork and eliminating the need to set an anti-fooling structure for the prefabricated formwork.

[0010] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead bottom plate structure for the cabinet, the left side part and the right side part are provided with the prefabricated grooves that are equal in height and opposite to each other left and right, and at least two are provided on each side. In this technical solution, the prefabricated grooves on each side of the prefabricated overhead bottom plate structure for the cabinet are set to at least two, with equal height and opposite to each other left and right, which not only does not increase the difficulty of prefabrication, but also further enhances the structural strength after assembly.

[0011] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead bottom plate structure for the cabinet, the cross section of the prefabricated groove is U-shaped, with the opening of the U-shaped facing outwards. The upper end of the prefabricated groove is an open grouting port, and the lower end is a closed structure. This technical solution sets the prefabricated groove in a special structural form, which is not only convenient for filling the corresponding opening space during prefabrication, but also convenient for prefabricated demoulding. At the same time, it is more convenient for grouting from the upper part and avoids the leakage of the slurry from the lower part.

[0012] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead bottom plate structure for the cabinet, the cross section of the prefabricated groove is concave, with the opening of the concave facing outwards. The upper end of the prefabricated groove is an open grouting port, and the lower end is a closed structure.

[0013] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead floor structure of the cabinet, the transition part between the left side part and the top side part is a prefabricated inclined plane, and the upper ports of the prefabricated grooves on the left side part all extend to the prefabricated inclined plane. In this technical solution, both the left and right sides of the upper end of the prefabricated overhead floor structure of the cabinet are set as prefabricated inclined planes. When two prefabricated overhead floor structures of the cabinet are butted, a groove can be formed along the width direction of the prefabricated overhead floor structure of the cabinet, and it is communicated with the prefabricated groove and the directions are perpendicular to each other. This not only facilitates grouting into the prefabricated groove, but also further enhances the connection strength between adjacent prefabricated overhead floor structures of the cabinet.

[0014] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead floor structure of the cabinet, the transition part between the right side part and the top side part is a prefabricated inclined plane, and the upper ports of the prefabricated grooves on the right side part all extend to the prefabricated inclined plane. In this technical solution, both the left and right sides of the upper end of the prefabricated overhead floor structure of the cabinet are set as prefabricated inclined planes. When two prefabricated overhead floor structures of the cabinet are butted, a groove can be formed along the width direction of the prefabricated overhead floor structure of the cabinet, and it is communicated with the prefabricated groove and the directions are perpendicular to each other. This not only facilitates grouting into the prefabricated groove, but also further enhances the connection strength between adjacent prefabricated overhead floor structures of the cabinet.

[0015] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead floor structure of the cabinet, the slopes of the two prefabricated inclined planes on both sides of the top side part are the same and symmetrically arranged. In this technical solution, both the left and right sides of the upper end of the prefabricated overhead floor structure of the cabinet are set as prefabricated inclined planes. When two prefabricated overhead floor structures of the cabinet are butted, a V-shaped groove can be formed along the width direction of the prefabricated overhead floor structure of the cabinet. The V-shaped groove is communicated with the prefabricated groove and the directions are perpendicular to each other. This not only facilitates grouting into the prefabricated groove, but also further enhances the connection strength between adjacent prefabricated overhead floor structures of the cabinet.

[0016] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead floor structure of the cabinet, the upper end surface of the top side part is provided with a prefabricated roughened surface.

[0017] On the basis of the above technical solution, as a preferred technical solution of the prefabricated overhead floor structure of the cabinet, the front side part, the left side part, the right side part and the top side part are all plate-shaped structures.
