Problems solved by technology

It is especially suitable for the connection of "+", "L", and "T" type building nodes, but self-tapping screws are still used to fix the joint between the stiffener and the formwork, so that its preparation requires a lot of manpower; the connecting rib is prepared into a W shape Difficult to control; the connection of different modules in the horizontal direction is complicated
[0006] The third evolution: the patentee Luo Dongwei in the patent number: "201010153360.7", the patent name: "expansion dragon skeleton assembly", the patent number: "200520013628.1", the patent name: "integral expansion keel", and the patent number: "201020506823.9 ", patent name: "Expanded keel with side self-contained connector" adopts a one-time forming expansion keel and fixed mold net buckle device, which avoids the waste of steel, but it is complicated to process and cannot be mass-produced
[0007] The fourth evolution: the patentee Luo Dongwei used reinforced C-shaped steel as the skeleton of the building formwork net in the patent number: "201120546052.0" and patent name: "A C-shaped keel". This method is relatively mature, but The connection with the mold net still needs to be connected by nails, and the materials used are expensive
[0008] Therefore, although the metal formwork in the building concrete wall has undergone four evolutions and has been greatly improved, the construction metal formwork still has the problems of complicated manufacturing methods and difficult processing during the construction process, and the materials used are relatively expensive. , the construction efficiency is low, and the ideal construction effect cannot be achieved during the construction process

Embodiment 1

[0031] Such as figure 1 , 3 , 4, 5, and 8, four vertical bars 1 arranged at rectangular corners are connected with the fixed rectangular stirrups 2 corners around them to form a steel bar cage, and the horizontal bars 4 hoops or welded on the steel bar On the cage, the formwork shear wall unit is formed. The reinforcement column cage in the formwork shear wall unit is connected to the steel mesh 3 through the connection member on the steel plate 7, and the connection member 6 between the reinforcement column cage and the steel plate 7 is a “Π”-shaped incision 10 on the steel plate, a “Π” shape Cutout 10 is turned over the connecting member 6 that the door type is bent down, as Figure 6 As shown, there is a U-shaped notch at the hanging end of the connecting member 6, and the U-shaped notch is snapped into and connected with the side of the vertical rib of the steel bar cage; 11, "I"-shaped cutout 11, the connecting member 5 that is bent in the door-to-door style on both si...

Embodiment 2

[0034] Such as figure 1 , 8 , shown in 9, four vertical ribs 1 arranged in rectangular corner positions are connected to a reinforcement column cage with 2 angles of rectangular stirrups surrounding and fixed around it, and 4 hoops of horizontal ribs or are welded on the reinforcement column cage to form Formwork shear wall elements. The reinforcement column cage in the formwork shear wall unit is connected with the steel mesh 3 through the V-shaped connecting member 12 and the U-shaped connecting member 13 on the connecting block 14, such as Figure 10 , 11 As shown, the steel mesh 3 is stuck into the V-shaped connector, and the V-shaped connector is folded and bent to form a through hole. The steel mesh 3 is firmly stuck in this through hole. The steel mesh 3 and the through hole can be welded again to strengthen Firmness; the steel column cage is snapped into the U-shaped connector, and the U-shaped connector is folded and bent in half to form a through hole, and the ver...

Abstract

Provided is a manufacturing method for a formwork shear wall assembled in a modularized mode. Steel reinforcement cage wall units are arranged, and each steel reinforcement cage wall unit is fixedly connected with nets on the two sides through connecting mechanisms between the sides of a steel reinforcement cage wall and the nets so that a framework shear wall unit assembled in a modularized mode can be formed. Each connecting mechanism is a steel plate with connecting members or is a connecting block formed by welding a U-shaped connecting part to a V-shaped connecting part in a crossed mode. The formed framework shear wall units are connected through the connecting mechanisms and the nets, assembled through vertical ribs or horizontal ribs in a connected mode and then filled with concrete in a pouring mode, and therefore the formwork shear wall assembled in the modularized mode is formed. Steel reinforcement column cages and the nets can be integrally manufactured in factories, and the modularized formwork shear wall is formed; according to dimension requirements of different shear walls, the multiple modularized formwork shear walls are arranged and spliced according to a required dimension so as to form a shear wall framework, and the concrete is poured into the framework. According to the method, operation is simple, construction efficiency is improved, and the construction progress is accelerated.

Description

technical field [0001] The invention belongs to the field of construction engineering, and relates to a formwork shear wall for construction, in particular to a formwork shear wall which can be combined with modules of any size. Background technique [0002] The traditional method of building a reinforced concrete wall is to use formwork arranged face to face, and pour concrete in the volume defined by the formwork. , recycle the template, and take out the locking part. For the reinforced concrete wall manufactured by this method, the wooden formwork is eliminated after being used several times, and the cost of using the steel formwork is too high, and it needs to be corrected after use; Or the air is difficult to discharge, and the construction quality is difficult to be guaranteed. [0003] With the development of the times, the construction industry is also constantly developing. In the construction of reinforced concrete walls, the use of metal building formwork instea...
