Abstract

Disclosed is a vertical mold for producing a prefabricated component, comprising vertical lateral mold parts, a bottom mold part and a top mold part which enclose a space for casting the prefabricated component. The bottom mold part and the top mold part are held between two of the vertical lateral mold parts, and a fastening structure is provided at the top of the vertical lateral mold parts for fastening two of the vertical lateral mold parts. Use of the vertical mold of the present invention offers a number of advantages. After formation of the prefabricated component and removal of the mold, the prefabricated component can be directly hoisted and transported, without the need for an erecting process. The disadvantage associated with horizontal casting of an insulation wall panel in which two concrete layers must be separately cast can be avoided, which improves production quality and enhances production efficiency. The invention enables casting of three-dimensional structures having various complex shapes, such as L, F, or E shapes, or ladder-like shapes with various numbers of horizontal bars. Further, each side of the prefabricated wall is well formed, without the need for an additional process of scraping it smooth.

Description

Vertical mold for producing prefabricated components

Technical field

The invention relates to a vertical mold for producing prefabricated components, which belongs to the technical field of prefabricated component production.

Background technique

Most of the existing concrete prefabricated components are produced by horizontal casting, that is, the prefabricated components are "laid flat" on the workbench. For example, Patent Document 1 (Publication No. CN108145834A) discloses a horizontal combination mold for producing prefabricated components. But the prefabricated components of horizontal combined mold mainly have the following technical problems:

1. After casting, the prefabricated components (wall panels, floor slabs, etc.) need to be turned 90 degrees for vertical transportation. The demoulding and lifting process is complicated and it is easy to cause damage to the prefabricated components.

2. When producing sandwich insulation wallboards, it is necessary to cast in layers, first cast the lower concrete layer, then arrange the middle insulation layer, and then cast the upper concrete layer, which not only increases the production cycle of prefabricated insulation wallboards, but also reduces the production efficiency. The insulation layer needs to be arranged on the production site, which is difficult to arrange and takes a long time on the production line.

3. There is no top mold for the horizontal combination mold. One side of the wall panel is formed by the surface of the workbench (steel trolley), and the other side is finished with a scraper after pouring. Only two walls with flat sides can be produced. It is convenient for manufacturing prefabricated walls with complex three-dimensional structures with L-shaped and C-shaped cross sections in the longitudinal direction.

4. There is no top mold for the horizontal combination mold, and the top surface should be scraped flat after the pouring is completed.

Summary of the invention

In order to overcome the problems of the existing horizontal combined molds, the present invention provides a vertical mold for producing prefabricated components. The specific technical solutions are as follows.

A vertical mold for producing prefabricated components, characterized in that it includes a vertical side mold, an end mold and a top mold for enclosing the casting space of the prefabricated components, the end mold and the top mold are clamped in two Between the vertical side molds; the top of the vertical side molds is provided with a clamping structure for clamping the two vertical side molds.

Among them, if the prefabricated member needs to retain the extended steel bars, a through hole for the extended steel bars to pass through may be opened in the end mold and/or the top mold.

Further, the clamping structure includes a clamping seat, a handle seat, a handle and a U-shaped connecting rod, the clamping seat is fixedly arranged on the top of one of the vertical side molds, and the handle seat is fixedly arranged on the other A top of the vertical side mold, the clamping seat has a groove, the opening of the groove faces away from the handle seat, the handle is hinged to the handle seat, and the U-shaped connecting rod The two end sections are hinged with the handle, and the U-shaped connecting rod can be engaged with the groove of the clamping base. When the U-shaped connecting rod is clamped with the clamping base, the handle is The hinge point of the handle base is located between the clamping point and the hinge point of the handle and the U-shaped connecting rod, and the line from the hinge point of the handle and the U-shaped connecting rod to the clamping point is located at the hinge of the handle and the handle base Between the point and the top mold. With the above clamping structure, once the U-shaped connecting rod is engaged with the clamping seat, it will form a self-locking, limiting the distance between the two vertical side molds to a certain range.

Further, the top mold is fixedly provided with a vertical positioning plate, and the positioning plate is provided with through holes distributed along the vertical direction; the top of the vertical side mold is provided with a support, and the support The upper opening is provided with a through hole; the bolt passes through the through hole of the positioning plate and the support at the same time to suspend the top mold between the two vertical side molds. The position of the top mold is restricted by the bolt to ensure that the top mold is in a predetermined position, wherein the positioning plate is provided with a series of through holes along the vertical direction, and these through holes can be used to adjust the height of the top mold to define the prefabricated member the height of. Further, a horizontal anti-falling plate is fixed on the top of the positioning plate, and the width of the horizontal anti-falling plate in the direction perpendicular to the vertical side mold is greater than the width of the top mold. The horizontal anti-falling plate can effectively prevent the top mold from falling to the bottom of the vertical side mold, and improves the safety and reliability when the top mold is installed and removed.

Further, the vertical side mold includes a rib plate and a molding plate for molding a prefabricated member, and the rib plate is fixed to the outer surface of the molding plate in a criss-cross manner. Among them, the side where the shaped plate contacts the prefabricated member is the contact surface, and the side opposite to the contact surface is the outer surface. The arrangement of the rib plate is beneficial to improve the rigidity of the vertical side mold, prevent the bending deformation of the molding plate, and improve the manufacturing accuracy of the prefabricated member.
