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

[0020] A method for fastening a formwork of a reinforced concrete member, comprising the following steps:

[0021] 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;

[0022] 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;

[0023] 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;

[0024] 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

[0028] The embodiment of the present invention is further limited on the basis of embodiment 1.

[0029] 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.

[0030] Further, preferably, holes are opened on the square plate.

[0031] 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.

[0032] Further, preferably, two buckles are provided on the column angle limiter, and they are distributed in a dislocation manner.

[0033] 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 fastening method of a formwork, in particular to a fastening method of a reinforced concrete member formwork, comprising: using a column angle limiter to calibrate the position of the formwork; The column angle limiter is fixed on the formwork; loosen the handle on the column angle limiter, insert the steel pipe into the buckle, and pull the handle to lock the steel pipe; pass the screw through the formwork and the steel pipe, and use an arc at the end of the screw Buckle the steel pipe with the shaped limit plate, and finally screw in the pair of shoulder nuts, push the limit plate to squeeze the steel pipe; inject concrete into the cavity between the formwork, stop, turn the shoulder nut, remove the arc limit plate, and Pull out the screw, loosen the handle on the column angle limiter, remove the steel pipe, and finally remove the column angle limiter to complete the fastening and disassembly; smooth the hole left by the screw rod with mortar. The invention has the advantages of simple operation, concise and reasonable structural arrangement, wide application range and good reinforcement effect. Solved 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...
