Concrete pump pipe horizontal hole fixing device

Abstract

The invention discloses a concrete pump pipe horizontal hole fixing device. The device comprises steel channels, bolts and rubber pads. The steel channels are fixedly arranged on the two sides of a horizontal hole of a concrete pump. Bolt holes which are centralized symmetry in the length direction are formed in the middle of the waist portion of the bottom surface of each steel channel. U-shapedopenings are formed in the side face where each steel channel abuts against the concrete pump pipe and are formed in the two sides away from a center line, and bolts can be erected on the U-openings.The steel channels are fixed to a slab surface on the upper side and a slab surface on the lower side of a slab by the bolts and lock nuts through the bolt holes in the bottom surfaces of the steel channels, and the steel channels arranged on the two sides of the concrete pump pipe are fixedly connected by the bolts and the locknuts through the U-shaped opening in the side faces of the steel channels. One rubber pad is arranged between each steel channel and the concrete pump pipe, and the rubber pad is fixedly arranged on the outer side face of the steel channel. According to the concrete pump pipe horizontal hole fixing device, materials such as the steel channels, the bolts and the rubber pads which are easy to purchase are mainly adopted, quite high safety is achieved during construction operation, high flexibility is achieved, and small influence is caused to construction operation.

Description

Technical field [0001] The invention belongs to the technical field of safe operation and protection of building construction concrete engineering, in particular to a horizontal hole fixing device for a concrete conveying pump pipe. Background technique [0002] In the construction of housing construction, the vertical transportation of concrete is to use a concrete pump truck to transport the concrete to the working floor through the pump pipe. The fixing of the pump pipe between the floors is the guarantee of the transportation efficiency and safe operation during the concrete transportation process. Before the device of the present invention is used, people usually reserve a suitable hole on the floor, and use wood squares and wooden wedges to violently fill the gap between the hole and the pump tube to plug the pump tube tightly to prevent the pump tube from shaking and falling off. This simple method of fixing the pump tube has extremely low protection safety and is easy to ...

This simple way of fixing pump pipes has extremely low protection safety, is easy to slip off, and pipe bursts often occur during construction

[0003] Through the analysis of this situation, we have concluded that if the concrete delivery pump pipe is not fixed firmly during the pump truck transportation operation, the pump pipe will vibrate with the pump truck delivery pressure. , with its fixing materials or floor slabs, there will be movement and friction, and then pipe bursts will sometimes occur during the transportation process, which seriously affects the concrete transportation efficiency and affects the continuity of concrete pouring. Therefore, it is necessary to design the horizontal opening of the concrete delivery pump pipe. Delivery pump tubing is more stable during operation
