Detailed Description
The embodiment discloses a construction method of a deformation joint of a shear wall structure.
Referring to fig. 1, the method includes the following steps: firstly, processing a template. And secondly, placing the inner mold. And thirdly, placing an outer die. And fourthly, erecting an inner die and penetrating a bolt for reinforcement. And fifthly, pouring concrete. And sixthly, hoisting and detaching the template.
The template processing method comprises the following steps:
firstly, preparing materials, wherein the materials to be prepared comprise: 14 mm's steel form, 90 mm's secondary joist and 3 mm's steel pipe are as main joist, a plurality of screws, and 3, 14mm steel pipes are as fixed pipe to the split bolt.
With reference to fig. 2, two main joists are taken, are vertically placed at intervals of 450mm, and are vertically fixed on the main joists, and the distance between two adjacent main joists is 240mm, the main joists and the steel formwork are fixed through bolts, the distance between the bolts close to one row of the ground and the ground is not more than 200mm, and the distance between the bolts close to one row of the ground and the ground is 220mm in the embodiment.
The fixing pipe is welded between the keels, so that the whole stress of the template is uniform, the nut 4 is welded on the fixing pipe every 500mm, and the template is provided with a through hole for the screw rod of the split bolt 3 to pass through.
Through welding nut 4 on the template, the dismouting is more convenient, makes the workman can carry out the reinforcement of template and demolish work in the opposite side (in the floor) of template.
The space in the movement joint is narrow and small, and the work of dismantling through inside the floor is more convenient.
And after the template is processed, fixing the inner film at a preset position, fixing the outer die at a preset position, and fixing the inner film and the outer die.
The split bolt 3 penetrates through the outer die to be in threaded connection with a nut 4 fixed on the inner die, and the side, far away from the inner die, of the outer die is fixed through the bolt.
In order to facilitate the removal of the formwork, in this embodiment, the bolt is sleeved with a through-wall pipe 6, so as to isolate the screw of the split bolt 3 from the wall body 5.
And pouring concrete between the inner mold and the outer mold to form the shear wall, and removing the template after the concrete is initially set.
The concrete mode of template demolition is:
and (4) disassembling from the outer die, rotating the bolt, and disassembling the bolt from the nut 4 of the inner die because the nut 4 is fixed on the template of the inner die.
The centre form is taken off the template through the mode of hoist and mount, because the position of movement joint is narrower and small, can't enter into the inside work of dismantling of movement joint, fixes through nut 4 and template, dismantles from the external mold department, and it is easier to dismantle.
In this embodiment, the inner mold and the outer mold are made of steel plates.
A steel formwork, with reference to FIG. 3, includes a plurality of formwork units 10, wherein one side of the formwork unit 10 is opened with a connecting groove 100, and the other side is extended with a connecting ridge 101.
Connecting stupefied 101 is the T style of calligraphy, and connecting groove 100 is the same with connecting stupefied 101 shape, and in order to make things convenient for the assembly of template, the connecting groove 100 top is provided with flared portion 102, connects stupefied 101 bottom and is provided with throat portion 103.
After the throat 103 is inserted from the flared portion 102, the two steel templates can be connected together.
For the convenience of hoisting, a hoisting ring 50 is fixedly connected to the top of the steel plate.
Concrete implementation process fixes interior template 1 and exterior sheathing 2, keeps away from external mold one side fixation nut 4 at the inner membrane, will carry out pouring of concrete after 3 are fixed to the stay bolt, forms the shear force wall, after the shear force wall initial set, carries out the template and demolishs, carries out demolishs the template in exterior sheathing department, takes off the interior mould through the waterproof of hoist and mount after taking off the stay bolt, because the space of movement joint is narrow and small, through demolishing the template in exterior sheathing department, it is more convenient.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
