Description

Technical Field

[0001] The utility model relates to the technical field of concrete precast production, in particular to a formwork for building concrete precast blocks. Background Technique

[0002] Precast wall panels are concrete wall panel components processed in precast factories or construction sites for building assembly, abbreviated as wall panels or panel walls. Using precast concrete wall panels to build precast large-panel buildings can improve the degree of factoryization and mechanization of construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period of buildings. And during the production of precast wall panels, formwork is needed to shape the concrete, and the poured concrete solidifies into precast components.

[0003] When current precast components are produced, concrete is injected into the forming groove. After solidifying and forming, the precast components need to be transported to the curing equipment for a period of curing work to ensure the quality of the finished product. And in order to ensure the integrity of the precast components during the curing process and avoid damage caused by compression and collision when stacked relative to each other, it is necessary to carry the formwork together into the curing equipment, and these formworks cannot continue to perform the pouring and forming work during the curing process, and there is room for improvement in work efficiency. Content of the Utility Model

[0006] A formwork for building concrete precast blocks includes a forming cavity, the forming cavity is movably clamped on the upper surface of the mold body, a vibration structure is relatively fixedly installed at the bottom side of the mold body, the forming cavity includes a bottom plate, the two sides of the bottom plate are hinged with first side plates, and the front and rear edges of the bottom plate are hinged with second side plates. The mold body includes a base, the upper surface of the base is fixedly connected with a mold base, a mold cavity slot is opened on the upper surface of the mold base, and push plates are movably embedded at the four corners of the bottom of the mold cavity slot. The bottom sides of the push plates are relatively fixedly connected with the output ends of hydraulic push rods.

[0009] Furthermore, the vibration structure includes a top block moving groove, the number of the top block moving grooves is three groups, and the number of each group is several. A vibration top block is movably installed inside the top block moving groove. Two first springs are fixedly connected to both sides of the bottom of the vibration top block. A sliding sleeve is fixedly installed in the middle of the bottom side of the vibration top block. The sliding sleeve is slidably sleeved on the upper end of the top column. A second spring is fixedly connected to the top of the top column. The lower end of the top column is hinged to the upper end of a connecting rod, and the lower end of the connecting rod is hinged to a crank.

[0010] Furthermore, the crank is fixedly installed in the middle of a rotating shaft. The number of the rotating shafts is three. A plurality of shaft seats fixedly connected to the bottom of the mold base are rotatably sleeved on the side surfaces of the rotating shafts. The three rotating shafts are interconnected by a synchronous pulley belt group. One end of each rotating shaft is fixedly connected to the output end of a driving motor.

[0012] Furthermore, the top block moving groove is opened at the bottom of the cavity clamping groove.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The precast block template is integrally designed as a split structure with the forming cavity and the mold body being independent of each other. The four side plates of the forming cavity are designed as movable first side plates and second side plates. During operation, the first side plates, the second side plates and the bottom plate form a complete forming cavity, and the forming cavity is clamped on the inner wall of the cavity clamping groove. The position states of the first side plates and the second side plates are limited by the cavity clamping groove. Then, concrete is poured into the forming cavity for casting. When taking out the finished precast block, each group of hydraulic push rods is used to push the bottom side of the bottom plate, so as to push the forming cavity together with the finished precast block out of the cavity clamping groove. The staff can carry the precast block to the curing equipment together with the forming cavity. By equipping with multiple forming cavities, the idle mold body can be utilized to continuously carry out the casting work of precast blocks, improving the production efficiency.

During the process of pouring concrete, the driving motor rotates the rotating shaft in the middle, and then the other two rotating shafts are synchronously rotated through the synchronous pulley belt group, and then each crank is rotated. The connecting rod is used to control the reciprocating movement of the top column in the up and down directions, continuously hitting the sliding sleeve, and the impact force is transmitted to the bottom plate through the vibration top block, so that the bottom plate is in a high-frequency and small-amplitude vibration state, playing a role similar to vibration for the poured concrete.
