Description

Technical Field

[0001] This utility model relates to a concrete pouring hopper device, belonging to the field of concrete pouring construction technology. Background Technology

[0002] During the secondary structural construction of structural columns, after the formwork is erected, a pouring port is usually opened at the top of the formwork. A concrete pouring hopper device is installed at the pouring port as a guide plate. Concrete is poured into the structural column using the traditional method, and the formwork can be removed after the concrete dries. However, current technology is not comprehensive and has the following drawbacks: 1. The hopper body and base are non-removable and cannot be repeatedly disassembled and reused. This makes it unsuitable for construction sites that require frequent changes in work environments or are limited by transportation conditions, resulting in traditional concrete pouring hopper devices being usable only once. 2. The lack of support legs reduces the overturning resistance coefficient of the base. Because the base cannot be stably supported, the probability of instability in a system without support legs is relatively high.

[0003] To solve one of the above problems, there is an urgent need for a concrete pouring hopper device. Utility Model Content

[0004] Based on the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to achieve a detachable connection between the hopper body and the base, and how to make the concrete slurry flow into the casting cavity composed of the casting template through the hopper body as a casting filler, so as to directionally cast narrow areas. To this end, a concrete casting hopper device is provided.

[0005] The concrete pouring hopper device of this utility model is characterized in that: it further includes a base, the upper surface of which is an inclined surface that fits against the lower surface of the hopper body, a connecting plate is provided at the bottom of the hopper body, a connecting bolt A is provided at the tail of the base, the connecting bolt A passes through the connecting plate and is connected to a nut, a snap-fit ​​seat is provided at the front end of the bottom of the base, a connecting seat is provided at the tail of the lower surface of the base, and a support leg is detachably installed at the bottom end of the connecting seat.

[0006] A notch matching the hopper body is made in the upper part of the casting template. Then, the base is snapped into the notch in the upper part of the casting template. Then, the connecting seat is connected to the support leg. The bottom end of the support leg is supported on the corresponding support surface, which supports the base. Then, the connecting plate on the hopper body is connected to the base through connecting bolt A and nut to complete the installation of the hopper body. The concrete slurry, as the casting filler, flows into the casting cavity composed of the casting template through the hopper body. It can be used to cast narrow areas in a directional manner, ensuring that the material accurately reaches the target position and avoiding waste and pollution caused by disorderly dumping.

[0007] The feed hopper body and base are detachable and can be repeatedly disassembled and used, making them suitable for construction sites that require frequent changes in working environments or are limited by transportation conditions.

A first upright plate is vertically connected to the rear end of the supporting base plate. The two ends of the support plate are respectively connected to the front end of the supporting base plate and the upper end of the first upright plate. At least one set of connecting bolts A is provided on the first upright plate. The inclination of the hopper body is adapted to the angle of inclination of the hopper body, which facilitates the outflow of material within the hopper body.

A tension spring is provided between the tailstock and the second upright plate, and the tension spring provides a pulling force to drive the tailstock closer to the second upright plate.

[0012] The tension spring provides a pulling force that drives the tailstock toward the second upright plate, so that the casting template is stably clamped between clamping plates A and B, and can adapt to casting templates of different thicknesses.

[0013] In any of the above embodiments, preferably, the connecting seat includes an upper support tube, the upper end of which is welded to a support base plate, and an upper connecting flange is provided at the bottom end of the upper support tube. The support leg includes a lower support tube, the top end of which is provided with a lower connecting flange.

The lead screw nut is threadedly connected to the lead screw, and a rotating handle and a pad are respectively provided at the upper and lower ends of the lead screw.

[0016] The distance between the pad and the crossbar can be changed by rotating the rotating handle, which is in conjunction with the lead screw nut, thereby changing the overall length of the support leg to adapt to the height position of the base and provide stable support for the base.

[0017] In any of the above embodiments, it is preferred that the connecting bolt assembly B is arranged in four sets around the center line of the lower support pipe, and the screw section of the connecting bolt assembly B passes through the bolt holes on the upper connecting flange and the lower connecting flange and is connected to the corresponding nut, and the upper connecting flange and the lower connecting flange are connected.
