Concrete formwork with adjustable hole template

Abstract

The invention discloses a concrete formwork with adjustable hole template. The concrete formwork with adjustable hole template comprises a formwork, both ends of the formwork are provided with lugs with splicing holes, a plurality of hole templates are arranged on the formwork in an inserted mode, the outside of the hole templates is slidably connected with a socket, connecting rods are rotatably arranged on the bottom of the hole templates, sliding blocks with positioning bolts are rotatably arranged on the connecting rods, a slide groove is formed in the bottom of the formwork, and the sliding blocks slide in the slide groove; a containing cavity is arranged in each hole template, a plurality of first liquid outlet holes are formed in the side face of each containing cavity, and a first pipe connection port is formed in the bottom of each containing cavity; a channel is formed in the containing cavity in a penetrated mode, a plurality of second liquid outlet holes are connected to the side wall of the channel, a convex ring is arranged at one end of the channel, a spring is arranged in the channel, a sealing plug is arranged at both ends of the spring, and a push rod penetrating through the convex ring is arranged on the sealing plug; and a second pipe connection port is formed in the other end of the channel, and a top block is arranged in the second pipe connection port. By adoption of the concrete formwork and concrete pouring method, the formwork demoulding is convenient, and the height of the hole template can be adjusted conveniently.

Description

technical field [0001] The invention belongs to the technical field of construction tools, in particular to a concrete formwork with adjustable hole molds. Background technique [0002] Concrete formwork is a necessary device when concrete is poured. Traditional concrete formwork is made of wood formwork or steel formwork. Wood formwork has the disadvantages of being not fireproof, perishable, and not durable, while steel formwork is bulky, expensive, and prone to rust. Therefore, at present, aluminum alloy formwork has been widely used in building construction. When pouring concrete, if it is necessary to process prefabricated holes in the concrete, it is generally realized by fixing steel bars on the formwork or inserting hole molds when pouring. However, it is very troublesome to take out the hole molds by this method. If you take out the hole molds When the cement has solidified, you need to continuously beat it with a hammer to take out the hole mold. The removal oper...

Problems solved by technology

When pouring concrete, if it is necessary to process prefabricated holes in the concrete, it is generally realized by fixing steel bars on the formwork or inserting hole molds when pouring. However, it is very troublesome to take out the hole molds by this method. If you take out the hole molds When the cement has solidified, it needs to be continuously tapped with a hammer to take out the hole mold. The removal operation is very troublesome. If the cement is not solidified when the hole mold is taken out, the shape of the hole will become distorted due to the fluidity of the cement and the effect of gravity.

At the same time, the existing hole molds generally do not have a depth adjustment device, and the depth of a hole mold cannot be adjusted after being fixed on the formwork, so the hole mold needs to be reprocessed when pouring concrete with holes of different depths
