Description
Technical field
The present invention relates to a kind of template, especially a kind of expansion joint shear wall formwork, when being used for house, Construction of highrise buildings
The shear wall at expansion joint (including subsiding crack, aseismatic joint, expansion joint) pours.
Background technique
In engineering construction process, with the progress of science and technology, the scale of building is increasing, and length is increasingly
It is long, more and more in Building Engineering Design to be related at expansion joint (including subsiding crack, aseismatic joint, expansion joint), the template at expansion joint
It is most important to pouring for expansion joint shear wall.In high-building construction, shear wall typified form peace is needed to tear flexible, turnover open
Often, artificial, saving material is saved.The shear wall formwork mode of two sides at the expansion joint of engineering construction at present are as follows: a, with same
The cystosepiment of wall thickness is used when template；B, using traditional steel form or plank sheathing.
At current expansion joint template construction have the disadvantage that a, with the cystosepiment of same wall thickness when template uses, can not
It removes, inconvenient and insecure, easily rise mould, while cystosepiment can not recycle, so that the cost of engineering construction is also corresponding
Increase；B, traditional steel form is from great, and location difficulty of constructing, at high cost, traditional plank sheathing itself is easily-deformable, and what is poured cuts
Power wall metope out-of-flatness；C, traditional split bolt is needed the shear wall formwork of expansion joint two sides while being fixed up, length
Long, stress is big, and inconvenient to use, materials are also more and it is necessary to which two sides shear wall can just unload after all reinforcing.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of expansion joint shear wall formworks, can be realized expansion joint shearing
Wall form can be removed, and can lift and be used in turn, and can also recycle, while the shear wall wall surface levelling poured, pour
When not spillage.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
A kind of expansion joint shear wall formwork, the sizing steel and wood composite template being arranged including two block gaps are formed for fastening two pieces
The self-control screw rod of steel and wood composite template and be mounted in lower-layer concrete for position be formed steel and wood composite template positioning device,
The sizing steel and wood composite template includes square steel tube skeleton, and square steel tube skeleton includes the square frame being made of square steel tube and rectangular
The multiple square steel duct keels of lower portion longitudinal gap setting, the side of square steel tube skeleton are provided with multiple be horizontally arranged at interval
Reinforcing bar back cord, the other side of square steel tube skeleton are provided with plank sheathing, and plank sheathing is separated into more by reinforcing bar back cord and square steel duct keel
A square region, the plank sheathing in each square region, which is provided with one, allows to make by oneself the circular hole that screw rod passes through.
Technical solution of the present invention further improvement lies in that: it is described composition square steel tube skeleton square steel tube be 40mm ×
40mm, with a thickness of the steel pipe of 3mm, reinforcing bar back cord is the useless steel bar end of diameter 22mm.
Technical solution of the present invention further improvement lies in that: described self-control screw rod one end is set as hook solid, makes screw rod by oneself
The other end is fastened by mountain type card and nut.
Technical solution of the present invention further improvement lies in that: between two sizing steel and wood composite templates of expansion joint side lead to
The fastening of self-control screw rod is crossed, one end of self-control screw rod hook solid is located in the closely sizing steel and wood composite template at expansion joint, and two fixed
Casing is arranged on self-control screw rod between fashioned iron wood gang form.
Technical solution of the present invention further improvement lies in that: the diameter of the self-control screw rod is 22mm, and the diameter of casing is
50mm, the diameter of casing are greater than the diameter of the circular hole on plank sheathing.
Technical solution of the present invention further improvement lies in that: the positioning device includes channel steel, for fixing the pre- of channel steel
The right angle screw rod being embedded in lower-layer concrete and the tapered cup nut for fixing right angle screw rod, the upper surface of channel steel are provided with gear
Plate, distance of the baffle apart from channel steel side are the thickness of sizing steel and wood composite template, are uniformly provided on channel steel side multiple fair
Perhaps the oval notch that right angle screw rod passes through.
Technical solution of the present invention further improvement lies in that: the channel steel (8) use 10# channel steel, the diameter of right angle screw rod
For 14mm, the width of oval notch is 16mm.
Technical solution of the present invention further improvement lies in that: there are two steel hanging rings for the setting of the upper end of square steel tube skeleton.
By adopting the above-described technical solution, the technological progress achieved by the present invention is:
The sizing steel and wood composite template that the present invention uses includes the square steel tube skeleton being made of square steel tube, the side of square steel tube skeleton
The transverse steel back cord of setting can increase the intensity of sizing steel and wood composite template, while reinforcing bar back cord is using useless steel bar end, symbol
The theory of the waste utilization advocated now, environmental protection is closed, plank sheathing is arranged in the other side of square steel tube skeleton, than traditional steel form weight
Amount is light, and the upper end of square steel tube skeleton is provided with hanging ring, and lifting is convenient, and in addition the template of steel and wood composite is reinforced than traditional plank sheathing
Effect is good, and the shear wall wall surface levelling after pouring, template can remove, and can repeat to be used in turn；
Self-control screw rod is also using useless steel bar end material, advocating environment protection theory, and the one end for making screw rod by oneself is set as hook solid, is made by oneself
Screw rod is used to fasten two sizing steel and wood composite templates of expansion joint side, and one end of self-control screw rod hook solid, which is located at, closely stretches
On the reinforcing bar back cord of the sizing steel and wood composite template of seam, the other end is fastened by mountain type card and nut, so that self-control screw rod installation
And convenient disassembly, can be removed after the solidification of expansion joint side shear wall, when disassembly will self-control screw rod to being pushed forward so that hook portion
Being detached from reinforcing bar back cord can be taken off self-control screw rod；
Channel steel in positioning device is fixed on lower layer's flooring by the tapered cup nut and right angle screw rod being embedded in lower-layer concrete
On, the oblong notch on channel steel can adjust the position of channel steel up and down, so that the upper surface of channel steel is concordant with lower layer's flooring, gear
The phenomenon that plate is by steel and wood composite Template Location of being formed, and template will not deviate when pouring, and is not in spillage, it is ensured that quality.
