Description

Technical Field

[0001] The present invention relates to the technical field of integrated pump room floor slab molding, in particular to a casting molding device and a casting method for integrated pump room floor slab molding. Background Art

[0002] The pump room structure of the pump station consists of a flow channel layer, a water pump layer, and a maintenance layer. (1) Flow channel layer: The flow channel layer is the basic structural layer at the bottom of the pump room. It is mainly responsible for guiding the water flow into the water pump, ensuring a smooth water flow and reducing hydraulic losses. The elevation of the flow channel layer of this project is ▽-1.0m~2.0m. (2) Water pump layer: It is the installation area for water pumps and supporting equipment, including core components such as impellers, guide vanes, and drive shafts. The elevation of the water pump layer of this project is ▽2.0m. (3) Maintenance layer: Located between the water machine equipment layer and the motor layer, it is dedicated to equipment maintenance and maintenance operations, also known as the maintenance platform. The elevation of the maintenance layer of this project is ▽7.0m.

[0003] According to conventional construction technology, the pump room structure is cast in two times. The first time, the water pump layer is cast to the elevation of ▽2.0m, leaving a horizontal construction joint, and then the structural reinforcement and formwork installation above ▽2.0m are carried out; the second time, the maintenance layer is cast to the elevation of ▽7.0m; the integral casting of the pump room structure has certain construction difficulties and requires high construction technology. However, for the characteristics of small pump stations with narrow water inlet channels and small slab area, the single floor area of this project is 3.4m*4.2m. Under the premise of ensuring construction safety, through the design of the formwork frame and the formulation of the casting process, the integral casting of the pump room main structure can be achieved, thereby saving construction time, improving quality and reducing construction costs.

[0004] However, when the main structure of the pump chamber is cast in one piece, the second-layer formwork is typically secured with temporary supports. After pouring, the bottom formwork must be removed piece by piece manually. Because the formwork is located in the middle of the pump chamber and encased in concrete, workers must access it and the bottom of the pump chamber structure to remove it. This makes it difficult for workers to exert force, and the monolithic structure creates a large bottom area for the formwork, making manual removal difficult. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the deficiencies of the prior art, the present invention provides a casting and molding equipment and a casting method for integrally molding the pump room floor slab. The invention is provided with a transmission rod group in a synchronous demoulding assembly to extend the hanger rod group into the bottom of the hanging mold assembly, so that the hanger rod group is connected to the hanging mold assembly, and then the support of the hanging mold assembly on one side by the cross bar is released, and the template of the hanging mold assembly on that side is removed by using the gravity of the cross bar, and then the template of the bottom of the hanging mold assembly on one side can be removed at one time. The advantages of the present invention are that when the main structure of the pump room is integrally cast, the construction of the second-layer hanging mold usually relies on temporary brackets for fixation, and the bottom template needs to be manually removed piece by piece after casting. Since the hanging mold is located in the middle of the pump room and is wrapped in concrete, workers need to enter between it and the bottom of the pump room structure to dismantle it. On the one hand, it is difficult for workers to apply force, and on the other hand, the integral structure causes the bottom area of the hanging mold to be large, and it is difficult to complete the demoulding process manually.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the present invention provides a casting and molding device and a casting method for integrally molding a pump room floor slab, which has the following beneficial effects:

[0020] 1. The casting and forming equipment supports the hanging formwork assembly in the combined formwork through a supporting frame. First, the columns in the supporting frame are fixed on the pump room base bottom formwork in the combined formwork, and then the cross bars are installed on both sides of the columns. The hanging formwork assembly is supported by the cross bars, so that the hanging formwork assembly is connected with the inner cavity of the casting formwork of the vertical wall, and the hanging formwork assembly, the pump room base bottom formwork and the casting formwork of the vertical wall are formed into a whole. After the casting is completed and the floor slab is cooled, the hanging rod group is extended into the bottom of the hanging formwork assembly through the transmission rod group in the synchronous demolding assembly, so that the hanging rod group is connected to the hanging formwork assembly, and then the support of the hanging formwork assembly on one side by the cross bars is released, and the formwork of the hanging formwork assembly on this side is removed by the gravity of the cross bars, so that the formwork at the bottom of the hanging formwork assembly on one side can be removed at one time.

[0021] 2. The casting and forming equipment connects the disconnected anti-overturning rod through the threaded tie rod and the threaded sleeve in the threaded adjustment mechanism. After the two ends of the anti-overturning rod are connected to the two adjacent columns, the nut on the threaded sleeve is rotated to make the nut and the threaded tie rod rotate relative to each other, thereby moving the threaded sleeve relative to the threaded tie rod, tightening the disconnected anti-overturning rod and tightening the two adjacent columns. After the adjustment is completed, the protective sleeve is put on the connection between the threaded sleeve and the threaded tie rod to prevent concrete from falling on the threaded sleeve and the threaded tie rod during pouring and affecting the use of the threaded adjustment mechanism.

[0022] 3. The casting and molding equipment connects the disconnected anti-overturning rod through the threaded tie rod and the threaded sleeve in the threaded adjustment mechanism. After the two ends of the anti-overturning rod are connected to the two adjacent columns, the nut on the threaded sleeve is rotated to make the nut and the threaded tie rod rotate relative to each other, thereby moving the threaded sleeve relative to the threaded tie rod, tightening the disconnected anti-overturning rod and tightening the two adjacent columns. After the adjustment is completed, the protective sleeve is put on the connection between the threaded sleeve and the threaded tie rod to prevent concrete from falling on the threaded sleeve and the threaded tie rod during pouring and affecting the use of the threaded adjustment mechanism.

[0023] 4. The casting and molding equipment is transmitted through the driven gear in the hanging rod group and the synchronous gear. When the synchronous gear rotates, it drives the driven gear and the driven shaft to rotate together. When the driven shaft rotates, it uses the thread cooperation with the mounting hole to realize the movement of the driven shaft, and then the driven shaft drives the hanging rod at its end to move relative to the hanging ring at the bottom of the cross mold. When the cross mold needs to be removed, the hanging rod is extended into the hanging ring at the bottom of the cross mold. At this time, the lock between the cross rod and the column is released, so that the cross rod is hung on the bottom of the cross mold through the hanging rod and the hanging ring. Then, a force is applied to the cross rod, and the cross mold is driven to be removed by the force and the gravity of the cross rod, so as to avoid the cross mold being located at the bottom of the hanging mold assembly and sandwiched between the hanging mold assembly and the bottom mold of the pump chamber base, which is difficult to remove manually.
