Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a prefabricated box-type transformer foundation composite bottom mold. Background Art

[0002] At present, in the process of distribution network construction, box-type transformer foundation is often used. The traditional construction methods can be divided into: on-site casting and precast concrete casting;

[0003] With the improvement of construction technology and the improvement of construction environmental assessment requirements, it is difficult to meet the construction needs of the project by using the on-site pouring method. Therefore, more construction units have changed the construction technology to precast concrete pouring and then install it on the construction site.

[0004] The existing box-type transformer foundation molds are mostly of fixed size in terms of the manufacturing specifications of prefabricated parts, that is, one mold can only produce prefabricated products of one specification; this results in the prefabrication production of a split box-type transformer foundation requiring multiple sets of molds of different sizes.

[0005] Therefore, a prefabricated box-type transformer foundation composite bottom mold is needed to improve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to provide a prefabricated box-type transformer base composite bottom mold to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A prefabricated box-type basic composite bottom mold mold comprises a bottom mold bottom plate, the lower end of the bottom mold bottom plate is fixedly connected to a bottom mold base, the bottom mold base upper surface is symmetrically provided with a bottom mold short side and a bottom mold long side on both sides, the bottom mold short side and the bottom mold long side are each provided with two and fixedly connected to form a frame body fixedly connected to the upper surface of the bottom mold base all around, a bottom mold conversion mold is slidably provided on the inner side of the bottom mold short side and the bottom mold long side, and different basic mold shapes are adjusted by sliding the bottom mold conversion mold.

[0009] As a preferred solution of the utility model, the bottom mold base is composed of a plurality of H-shaped steels and I-shaped steels fixed in a horizontal and vertical array, and a plurality of fixing bolts are threadedly connected to the bottom mold base.

[0010] As a preferred solution of the utility model, a sealing strip is provided at the connection between the bottom mold bottom plate and the upper surface of the bottom mold conversion mold.

[0011] As a preferred solution of the utility model, a plurality of lifting ears are fixedly connected to both sides of the short side and the long side of the bottom mold.

[0012] As a preferred solution of the utility model, the bottom mold conversion mold is integrally formed by welding a plurality of sheet metal parts and built-in ribs, and a rubber strip insertion slot is provided at the bottom of the bottom mold conversion mold.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, by changing the position and shape of the bottom mold conversion mold, the rapid production of base plates of different shapes can be achieved, the production applicability of the prefabricated box-to-base mold can be improved, the cost expenditure of the enterprise's prefabricated mold can be reduced, the mold stacking and management costs can be reduced, and the mold utilization rate can be improved.

[0015] 2. In the present invention, in order to prevent the mold from leaking during pouring, a sealing strip is provided on the mold contact surface of the movable part of the mold, which effectively prevents the mortar from flowing out. BRIEF DESCRIPTION OF THE DRAWINGS
