Problems solved by technology

Large investment, poor effect, high requirements for manual operation, prone to problems of mold swelling and sand corners
[0003] At present, Chinese patent CN207878929U discloses a formwork fastening system with a pawl device and Chinese patent CN206971726U discloses a plate-shaped formwork fastening device, but these two methods are only suitable for the construction of small-volume concrete components In the middle, the scope of application is not wide enough
[0004] Therefore, a fastening method for reinforced concrete formwork is provided to solve the problem of inconvenient use

Embodiment 1

[0025] A method for fastening a formwork of a reinforced concrete member, comprising the following steps:

[0026] Step 1: In the process of pouring reinforced concrete components, use the column angle limiter to calibrate the position of the formwork, so as to ensure that the formwork can be spliced ​​in pairs to form the right angle of the components, and initially support the formwork;

[0027] Step 2: After initially supporting the formwork, use iron nails to fix the column corner stopper on the formwork through the holes in the column corner stopper;

[0028] Step 3: Loosen the handle on the column angle limiter, insert the steel pipe into the buckle, and pull the handle to lock the steel pipe;

[0029] Step 4: Pass the screw in the tension reinforcement through the template and the steel pipe, use the arc-shaped limit plate in the tension reinforcement to buckle the steel pipe at the end of the screw in the tension reinforcement, and finally screw in the tension reinforc...

Embodiment 2

[0033] The embodiment of the present invention is further limited on the basis of embodiment 1.

[0034] Further, preferably, the column corner limiter is composed of two square plates, the two square plates are vertically fixed, and the two square plates are integrally fixed.

[0035] Further, preferably, holes are opened on the square plate.

[0036] Further, preferably, steel pipe grooves are provided on the square plate, and the steel pipe grooves can make the steel pipes more closely and reliably adhere to the surface of the formwork.

[0037] Further, preferably, two buckles are provided on the column angle limiter, and they are distributed in a dislocation manner.

[0038] Further, preferably, the tension reinforcement is composed of a screw, a shoulder nut and an arc-shaped limiting plate, the screw is arranged outside the arc-shaped limiting plate, and the shoulder nut is arranged at the connection between the arc-shaped limiting plate and the screw .

Abstract

The invention relates to a method for fastening a template, in particular to a method for fastening a reinforced concrete member template. The method comprises the following steps: the position of thetemplate is calibrated by using a column angle limiting piece; the column angle limiting piece is fixed on the template by using an iron nail through a hole on the column angle limiting piece; a handle on the column angle limiting piece is loosened, a steel pipe is inserted into a buckle, and the handle is pulled to lock the steel pipe; a screw rod is penetrated through the template and the steelpipe, the steel pipe is buckled at the end of the screw rod by using an arc-shaped limiting plate, and finally a pair of shouldered nuts is screwed in to push the limiting plate to extrude the steelpipe; the concrete is injected into a cavity between the templates and keeps static; the shouldered nuts are rotated, and the arc-shaped limiting plate is detached; the screw rod is pulled out, the handle on the column angle limiting piece is loosened, the steel pipe is removed and finally the column angle limiting piece is removed; the fastening and disassembly work is completed; the hole left bypulling the screw rod is plastered with mortar. The fastening method has the advantages of simple operation, simple and reasonable structure arrangement, wide application range and good reinforcing effect, and solves the problem of inconvenient use.

Description

technical field [0001] The invention relates to a fastening method of a template, in particular to a fastening method of a reinforced concrete member template. Background technique [0002] In the process of pouring concrete frame columns at the construction site, workers often use the traditional process of double steel pipes and double tension screws to strengthen the formwork. The turnover materials, iron nails, screws and other sporadic materials are too large, and it is difficult to contain them. Each floor is tightly packed. The fastening device can only fasten the two perimeters of the component formwork. The investment is large, the effect is poor, and the requirements for manual operation are high, and the problems of mold expansion and sand angle are prone to occur. [0003] At present, Chinese patent CN207878929U discloses a formwork fastening system with a pawl device and Chinese patent CN206971726U discloses a plate-shaped formwork fastening device, but these t...
