Description

Technical Field

[0001] This utility model relates to the field of precast beam manufacturing technology, and in particular to a control device that can adjust the length of precast beams in multiple directions. Background Technology

[0002] Precast beams refer to concrete beam components that are prefabricated in a factory and then transported to the construction site for installation. Their production process encompasses standardized procedures such as formwork assembly, rebar tying, and concrete pouring and curing. Factory production improves the quality and stability of components and shortens the construction cycle by up to 50%. They are primarily used in the superstructure support systems of bridges and buildings.

[0003] However, in existing technologies, the sealing components and side templates of existing mold assemblies for precast beams are generally fixed together using bolts. The sealing components are often installed in fixed positions on the side templates. If multiple horizontally different threaded hole mounting points are set on the side templates, unused threaded hole mounting points are prone to blockage when concrete is poured into the mold assembly. This prevents the mold assembly from adjusting the length of the precast beams. Furthermore, the fixed threaded hole mounting points prevent mold assemblies capable of installing vertical sealing components from being compatible with inclined sealing components, making it impossible to adjust the angles of both ends of the precast beams in multiple directions, thus reducing practicality. Moreover, to ensure the stability of the sealing components on the side templates, multiple bolts are usually installed. Therefore, before installing and fixing the sealing components, their through holes need to be aligned with the corresponding threaded holes on the side templates, and the sealing components need to be adjusted to the correct installation position. If the sealing components are accidentally displaced before bolt installation, they need to be readjusted, which is time-consuming. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: the installation of sealing components on the side template is often in a fixed position. If multiple threaded hole installation points are set on the side template, unused threaded hole installation points will also become blocked when concrete is poured into the mold assembly, resulting in the mold assembly being unable to adjust the length of the precast beam slab. At the same time, due to the fixed threaded hole installation points, the mold assembly that can install vertical sealing components cannot be compatible with the installation of inclined sealing components, making it impossible to adjust the angle of the two ends of the precast beam slab in multiple directions, resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a control device for multi-directional adjustment of the length of precast beams and slabs, comprising a base, side templates provided on both sides of the base, and an installation rod connected through the bottom end of the side templates, one end of the installation rod being threadedly connected to the surface of the base, and a blocking plate being threadedly connected to the surface of the installation rod, a support leg being fixedly connected to one side surface of the side templates, a sealing component being placed on the upper surface of the base at the position between the side templates, and a connecting component being fixedly installed on the surface of the sealing component, threaded rods being fixedly connected to both ends of the side templates, and an installation groove plate being inserted through the surface of the threaded rod, and a nut being threadedly connected to the surface of the threaded rod, a retaining screw being placed in the groove of the installation groove plate, and one end of the retaining screw being threadedly connected to the connecting component, and positioning components being threadedly connected to the front and rear sides of the mounting groove plate on the surface of the retaining screw.

[0006] In a preferred embodiment, a concrete pad is fixedly connected to the bottom surface of the support leg.

[0007] In a preferred embodiment, a slot is provided on the top surface of the support leg, and a horizontal sway screw is placed in the slot. Both ends of the horizontal sway screw are threaded with limit plates at positions on one side of the support leg.

[0008] In a preferred embodiment, a circular through hole is formed on the surface of the sealing member, and a corrugated pipe is inserted through the circular through hole.

[0009] In a preferred embodiment, the gaps between the sealing element and the base and the side template, as well as the gaps between the corrugated pipe and the circular through hole, are filled with expanding foam.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] In this invention, after the sealing component is placed on the base between the side templates, the abutment screw rod passes through the groove of the mounting plate and one end connects with the connecting piece. At this time, the sealing component can be moved and adjusted back and forth on the base. After adjustment, the positioning piece installed on the abutment screw rod is rotated and moved to both sides of the mounting plate to position the sealing component, ensuring its stability after adjustment. The connecting piece at the installation point of the sealing component is located on its front side, which facilitates ensuring that the connecting pieces on both vertical and inclined sealing components can connect with one end of the abutment screw rod on the mounting plate, allowing them to be installed interchangeably. This enables multi-directional adjustment of the length and angle of the precast beam slab, improving its practicality.

[0012] The groove on the mounting plate installed on the side template and the mating part on the sealing component are on the same horizontal line and correspond one-to-one. When the sealing component is adjusted back and forth between the side templates, the groove on the mounting plate and the mating part on the sealing component will not be misaligned. This makes it easy for the abutment screw to pass through the groove on the mounting plate and connect with the mating part on the sealing component. Then, the positioning part installed on the abutment screw is rotated and moved to both sides of the mounting plate to complete the positioning and installation operation of the sealing component. Thus, the sealing component does not need to be adjusted and aligned with the groove on the mounting plate during installation, saving installation time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a control device for multi-directional adjustment of the length of precast beams and slabs, including a base 1, side templates 2 are provided on both sides of the base 1, and an installation rod 3 is connected through the bottom end of the side template 2. One end of the installation rod 3 is threaded to the surface of the base 1, and a blocking plate is threaded to the surface of the installation rod 3. With the help of the installation rod 3 and the support leg 4, the side template 2 is fixedly installed on both sides of the base 1. The support leg 4 is fixedly connected to one side surface of the side template 2, and the support leg 4 provides support for the placement of the side template 2. A sealing member 8 is placed on the upper surface of the base 1 at the position between the side templates 2, and a sealing member 8 is fixedly installed on the surface of the sealing member 8. The side template 2 is equipped with a docking part 9. Threaded rods 11 are fixedly connected to both ends of the side template 2, and mounting slots 12 are inserted through the surfaces of the threaded rods 11. Nuts 13 are threaded onto the surfaces of the threaded rods 11. With the help of the threaded rods 11 and nuts 13, the mounting slots 12 are fixedly installed on the side template 2. A retaining screw 14 is placed in the slot of the mounting slot 12, and one end of the retaining screw 14 is threaded into the docking part 9. Positioning parts 15 are threaded onto the surfaces of the retaining screw 14 at the front and rear positions of the mounting slot 12. When the sealing part 8 is placed on the base 1 at the position between the side templates 2, the retaining screw 14 passes through the mounting slot 12. The groove of 2 is made so that one end of it is connected to the connecting piece 9. At this time, the sealing piece 8 can be moved and adjusted back and forth on the base 1. After the adjustment is completed, the positioning piece 15 installed on the abutting screw 14 is rotated and moved to both sides of the mounting groove plate 12 to position the sealing piece 8, ensuring the stability of the sealing piece 8 after adjustment. The mounting point of the sealing piece 8 is set on the front side, so as to ensure that the connecting piece 9 on both the vertical sealing piece 8 and the inclined sealing piece 8 can be connected to one end of the abutting screw 14 on the mounting groove plate 12, so that the two can be installed interchangeably. This allows for multi-directional adjustment of the length and tilt angle of the precast beam slab, improving practicality. The groove on the mounting plate 12 installed on the side template 2 and the mating part 9 on the sealing part 8 are on the same horizontal line and correspond one-to-one. When the sealing part 8 is adjusted back and forth between the side templates 2, the groove on the mounting plate 12 and the mating part 9 on the sealing part 8 will not be misaligned. This makes it easy for the abutment screw 14 to pass through the groove on the mounting plate 12 and connect with the mating part 9 on the sealing part 8. Then, the positioning part 15 installed on the abutment screw 14 is rotated and moved to both sides of the mounting plate 12 to complete the positioning and installation operation of the sealing part 8. Thus, the sealing part 8 does not need to adjust and align the mating part 9 with the groove on the mounting plate 12 during installation, saving installation time.

[0022] Example 2

[0023] like Figure 1-4As shown, a concrete pad 5 is fixedly connected to the bottom surface of the support leg 4. By setting the concrete pad 5 and fixing it to the ground, the force-bearing area is increased and the pressure of the support leg 4 on the ground is distributed, preventing local ground collapse or damage due to overload. A groove is opened on the top surface of the support leg 4, and a horizontal swing rod 6 is placed in the groove. Both ends of the horizontal swing rod 6 are threaded with limit plates 7 at the positions on one side of the support leg 4. The limit plates 7 limit the stability of the horizontal swing rod 6 when it is placed at the top groove of the support leg 4. The addition of the horizontal swing rod 6 enhances the lateral stability of the side template 2 when it is installed on the base 1. To reduce deformation and ensure the accuracy and quality of beam and slab forming, the sealing component 8 has a circular through hole on its surface, through which a corrugated pipe 10 is inserted. The corrugated pipe 10 serves as a channel for the prestressing tendons, ensuring the accurate positioning of the prestressing tendons and preventing displacement or deformation during construction. At the same time, it isolates the prestressing tendons from the external environment, preventing corrosion or mechanical damage and extending their service life. The gaps between the sealing component 8 and the base 1 and the side template 2, as well as the gaps between the corrugated pipe 10 and the circular through hole, are filled with expanding foam. The addition of expanding foam improves the sealing performance of these areas, ensuring that leakage is reduced during concrete pouring.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
