Description

A partially reinforced back flute for a new type of aluminum-wood composite formwork system

technical field

The utility model relates to a novel aluminum-wood composite formwork system for formwork engineering and construction, and is particularly suitable for the connection of beam bottoms and end plates, and the connection of secondary beam early demolition systems.

Background technique

The formwork system currently used in China (aluminum formwork, steel formwork, wood formwork, and glued formwork) is connected by punching holes on the edge of the formwork, using pins, bolts and nuts to pass through the connection, and the connection of the end plate with the help of scaffolding Steel pipe or horizontal back-to-back connection, the edge sealing of the formwork will weaken the overall force of the formwork, damage the formwork, and the wrong hole position will affect the efficiency and quality of the formwork construction and reduce the standard rate of the formwork; the installation of full steel pipes is inconvenient for construction operations. Improving the connection between the beam bottom and the end plate is beneficial to the application of the early demolition system.

Utility model content

The purpose of the present invention is to provide a fixture suitable for a new type of aluminum-wood composite formwork system in order to overcome the defects of the above-mentioned prior art. There are special-shaped holes at a certain distance on the edge of the formwork of the new system. Shape and function of making formwork edge-sealing pull rods, one side of the pull rods is equipped with disc gaskets for fixing square steel pipes, and the disc gaskets are welded to the components (rotating bolts) as a whole, and the disc gaskets are turned by rotating the handle on the nut Fasten the square steel pipe, and the light round steel bar connected with the coarse screw rod passes through the shaped hole of the formwork edge to block the formwork edge.

The purpose of this utility model is achieved through the following technical solutions:

A local reinforced back corrugation for a new type of aluminum-wood composite formwork system for construction. The utility model includes two square steel pipes, hexagonal nuts connected between the two square steel pipes, and coarse tooth screw rods screwed into the hexagonal nuts respectively. The limit head set on the coarse tooth screw rod, the smooth round steel bar socketed with the coarse tooth screw rod, the disc gasket and steel sheet set on the back side of the smooth round steel bar, screwed into the rear section of the coarse tooth screw rod with nuts , a rotating handle is fixedly connected to the nut.

In the utility model, two square steel pipes are connected as a whole by hexagonal nuts, the thick tooth screw rod and the light round steel bar are welded as a whole, the disc gasket and the steel sheet are welded as a whole, and the nut and the rotating handle (9) are welded as a whole. overall.

The utility model is to assemble the disc gasket, the nut and the coarse tooth screw rod into a whole, and the two steel pipes are welded into a whole by the nut, and the thick tooth screw rod passes through the nut to connect the special-shaped hole of the sealing edge, and the disc The gasket clamps the square steel pipe to fix the square steel pipe and formwork edge sealing.

The beneficial effect of the utility model is that after using the utility model, the utility model can be used to reinforce the back side at the position where the template is weakly stressed according to the actual situation of the template force, without using the back side on all templates. Square reinforcement. Therefore, without weakening the strength of the formwork system, the usage of the back side can be effectively reduced, and the economic benefit can be improved.

Description of drawings

Fig. 1 is a schematic diagram of the three-dimensional structure of the utility model.

detailed description

As shown in Fig. 1, a partially reinforced back corrugation for a new type of aluminum-wood composite formwork system, including two square steel pipes 1, a hexagonal nut 2 connected between the two square steel pipes 1, and a thick hexagonal nut 2 screwed into the hexagonal nuts 2 respectively. Screw rod 3, the limit head 4 that is vertically arranged on the screw rod 3 of coarse teeth, the light round steel bar 5 that is socketed with the screw rod 3 of thick teeth, the disc spacer 6 and the steel bar that are arranged at the rear side of the smooth round steel bar 5 Sheet 7 adopts nut 8 to be screwed into the rear section of coarse tooth screw mandrel 3, and is fixedly connected with a rotating handle 9 on nut 8.

Two square steel pipes 1 of the utility model are connected as a whole by hexagonal nuts 2, the thick-threaded screw rod 3 and the smooth round steel bar 5 are welded as a whole, the disc gasket 6 and the steel sheet 7 are welded as a whole, and the nut 8 and the rotating handle are welded as a whole. 9 welding connection as a whole.

The utility model assembles the disc gasket, the nut, and the coarse screw rod into a whole. The two steel pipes are welded into a whole through the nut. The gasket clamps the square steel pipe to fix the square steel pipe and formwork edge sealing.

Installation instructions

1. As shown in attached drawing 1, the gasket and edge-sealing tie rod of the present utility model are specially customized according to the use function of the edge-sealing hole shape of the new building aluminum-wood composite formwork system. The steel bar is covered with a disc gasket connected to the rotating handle on the other side, and the moving range of the gasket is controlled by operating the rotating handle, so as to strengthen the edge sealing of the formwork and the square steel pipe;

2. The two steel pipes 1 are welded together by nuts. The length range can be determined according to the size of the concrete pouring at the end. The distance between the nuts is easy to operate;

3. The shape and size of the smooth round steel bar 5 welded at the end of the edge banding tie rod (component 1) can be determined according to the shape and function of the special-shaped hole in the edge banding of the formwork. The tie rod (component 1) and the gasket (component 2) are a single component. Can be assembled and used flexibly;

4. The rotating handle 9 and the nut 8 are welded as a whole, and the nut is connected with the gasket. The handle is easy to use and convenient to operate and control the gasket.
