Description

A movable tooling for the production of concrete prefabricated components

technical field

The invention relates to the technical field of production of prefabricated parts, in particular to a movable tooling used for the production of concrete prefabricated parts.

Background technique

With the rapid development of prefabricated buildings in China, the production technology of prefabricated components is also becoming more and more mature. At present, prefabricated components are mostly produced by mould casting. In the actual production process of prefabricated components, in order to meet the requirements of production or construction, prefabricated components are usually embedded with a variety of embedded parts; the existing embedded parts on the market It can be roughly divided into embedded parts for construction, embedded parts for production, temporary embedded parts and electrical embedded parts. The positions of the embedded parts in the prefabricated components are often uneven according to the specific construction requirements, so that the existing integral tooling often cannot be reused, resulting in a great waste of production resources.

The Chinese patent with application number: 2018108799877 discloses a movable tooling for the production of concrete prefabricated components, including a main bridge frame, side form connection supports arranged on both sides of the main bridge frame in the length direction, and embedded parts arranged on the main bridge frame The connection support, the side mold connection support and the embedded part connection support are all arranged in a sliding manner in the length direction of the main bridge, and the main bridge is also provided with a detachable fixed side mold connection support and The embedded part is connected to the first fastener of the support. The main bridge frame is fixedly erected on the pouring mold through two sets of side mold connecting supports, and each embedded part is respectively fixed on the corresponding embedded part connecting support. At the same time, the side mold connecting support and the embedded part connecting support are slidingly arranged on the main bridge at the same time, and cooperate with the first fastener used to detachably fix the side mold connecting support and the embedded part connecting support. Under the premise of ensuring the stability of each embedded part during pouring, not only the distance between the two sides of the die connecting support can be adjusted according to the design requirements, but also the connecting support of each embedded part can be adjusted according to the design drawing of each embedded part. The position can be adjusted flexibly. In this way, the movable tooling can be adapted to a variety of working conditions and meet diverse design requirements, so that its versatility is greatly improved, its reuse is facilitated, and the waste of production resources is greatly reduced.

In the process of producing prefabricated parts, sometimes the distance between several embedded parts in a row is fixed, and the overall position of several embedded parts is changed, and the overall position of the embedded parts needs to be offset. In the above-mentioned movable tooling, when the positions of several embedded parts in a row need to be adjusted, it is necessary to loosen the bolts one by one to adjust the distance after the embedded parts are connected to the support, which is troublesome to adjust.

SUMMARY OF THE INVENTION

In view of the deficiencies in the prior art, the purpose of the present invention is to provide a movable tooling for the production of concrete prefabricated components, the movable tooling can integrally move the connection supports of the embedded parts on a row by means of screw movement. , you only need to measure the distance once, which is more convenient to operate.

The above-mentioned purpose of the present invention is achieved through the following technical solutions:

The present invention is further provided that: the threaded end of the first bolt is rotatably connected with a circular arc sheet, the circular arc sheet is attached to the outer wall of the pipe body, and the inner wall of the installation through hole is provided with a circular arc sheet for the circular arc sheet to be relatively A mounting groove for sliding the first bolt in the axial direction.

By adopting the above technical solution, the arrangement of the circular arc sheet can increase the frictional force between the first bolt and the pipe body, so that the pipe body is less likely to rotate when it is fixed by the first bolt.

The present invention further provides that: the screw rod is fixed with the side die connecting support through the second bolt.

By adopting the above technical solution, the arrangement of the second screw makes the screw less likely to rotate during the process of pouring cement into the casting mold.

The present invention further provides that: the screw rod includes a thread segment and a manipulation segment, and the manipulation segment is hinged on the thread segment.

By adopting the above technical solution, in normal times, the control section hangs down naturally, making it difficult for foreign objects to touch the control section, so that the screw is less likely to rotate.

The present invention further provides that: the manipulation section is flat.

By adopting the above technical solution, the flat control section is less likely to be touched when it is in a naturally hanging state.

To sum up, the beneficial technical effects of the present invention are:

1. The whole prefabricated connection support on a screw can be moved as a whole by means of screw movement, which is simpler and more convenient to operate.

2. When the screw is rotated, several prefabricated connection supports on the screw can also be fixed, and the prefabricated connection support that you want to move can be moved, so as to adapt to the needs of more different working conditions.
