Description
Technical Field
The invention belongs to the technical field of concrete prefabricated parts, and particularly relates to a pipeline pre-embedded expansion piece in a concrete prefabricated part.
Background
The precast concrete is a building member, including beams, plates, columns, and building finishing accessories, which is previously manufactured in a factory using concrete as a basic material. During production and processing, various holes must be reserved on the concrete prefabricated member according to design requirements to meet the later installation requirements of water, electricity and gas, and the traditional reserved hole forming method is to adopt an embedded sleeve or a wood template for manufacturing. However, the sizes of the apertures are different, the traditional method is high in cost, time-consuming and labor-consuming, and slow in construction progress, so that research and development personnel are required to provide a concrete prefabricated member preformed hole mold to solve the problems in the prior art.

In order to solve the problems, the invention discloses a pipeline pre-embedded expansion piece in a concrete prefabricated part, which has the advantages of simple and practical structure, convenience in operation and adjustability and can meet the requirements of apertures with different sizes.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the utility model provides a pre-buried expansion bend of pipeline in precast concrete spare, includes magnetism base, backup pad, regulating plate, the magnetism base sets up in the backup pad below, and the backup pad middle part is equipped with bolt connection magnetism base, is equipped with three screw in a bolt outside, the regulating plate is rectangular board, and regulating plate quantity is three, and the regulating plate middle part is equipped with rectangular hole, and bolt two passes screw and rectangular hole, fixes the regulating plate in the backup pad, and three regulating plate evenly sets up, and the regulating plate head is the arc, and the regulating plate afterbody is just to the bolt head of bolt one.
As an improvement of the invention, the supporting plate is provided with guide grooves, the lower part of the adjusting plate is provided with guide blocks, the guide blocks are arranged in the guide grooves, and the angle between every two adjacent guide grooves is 120 degrees.
As an improvement of the invention, the adjusting plate is provided with scales.
As an improvement of the invention, the supporting plate is of a triangular structure.
As a modification of the present invention, the bolt head of the first bolt is hexagonal.
The invention has the beneficial effects that:
the pipeline pre-buried expansion piece in the concrete prefabricated part is simple and practical in structure, convenient to operate and adjustable, and can meet the requirements of apertures of different sizes.

List of reference numerals:
1. the magnetic base comprises a magnetic base body, 2, a supporting plate, 3, an adjusting plate, 4, bolts I and 5, strip holes, 6, bolts II and 7, an adjusting plate head, 8, a guide groove, 9 and scales.
Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in the figures, the pipe pre-buried expansion piece in the concrete prefabricated part comprises a magnetic base 1, a supporting plate 2 and adjusting plates 3, wherein the magnetic base 1 is arranged below the supporting plate 2, a first bolt 4 is arranged in the middle of the supporting plate 2 and connected with the magnetic base 1, three screw holes are formed in the outer sides of the first bolt 4, the adjusting plates 3 are strip plates, the number of the adjusting plates 3 is three, a strip hole 5 is formed in the middle of each adjusting plate 3, a second bolt 6 penetrates through the screw holes and the strip hole to fix the adjusting plates 3 on the supporting plate, the three adjusting plates 3 are uniformly arranged, the heads 7 of the adjusting plates are arc-shaped, and the tail portions of the adjusting plates 3 are opposite to the heads of the first bolts 4.
According to the pre-buried expansion piece for the pipeline in the concrete prefabricated part, the position of the pipeline is calculated according to the requirement of a drawing, a mark is made on a vibration platform, the magnetic base 1 is attracted to the mark position, the second bolt 6 is loosened to adjust the length of the adjusting plate 3, the size of an excircle formed by the heads 7 of the three adjusting plates is the inner diameter of the pipeline, a plastic plate (which is in a circular shape) is placed on the periphery of the expansion piece after the second bolt 6 is fastened, the expansion piece and the plastic plate are taken away after the second bolt 6 is loosened after maintenance forming, and the remained hole is a pipeline pre-buried hole.
According to the invention, the guide grooves 8 are formed in the support plate 2, the guide blocks are arranged below the adjusting plate 3 and are arranged in the guide grooves 8, the angle between every two adjacent guide grooves 8 is 120 degrees, the adjusting plate 3 cannot rotate in angle when moving, the reserved holes are circular, and the deformation is small.
The adjusting plate 3 is provided with the scales 9, so that the moving distance can be accurately adjusted, and the three adjusting plates are ensured to have the same moving distance.
The support plate 2 is of a triangular structure.
The bolt head of the first bolt 4 is hexagonal and also corresponds to a limiting block at the tail part of the adjusting plate 3, the tail part of the adjusting plate 3 cannot retreat when retreating to the bolt head of the first bolt 4, and otherwise, the quality of the pipeline embedded hole is influenced.
The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features.
