[0002] The traditional wall column pouring form is composed of wood board and wood frame by screw rod and bolt opposite pulling fixation, in the use process, the wood frame is easy to deform, break and damage, and further influence concrete pouring quality and pouring efficiency. UTILITY MODEL CONTENT

[0003] The utility model discloses a concrete pouring form, and solves the technical problem that the wood frame is easy to deform, break and damage in the prior art.

[0004] In order to realize the above-mentioned purpose, the utility model provides a concrete pouring form, and the technical scheme is as follows:

[0005] The concrete pouring form comprises a wood board, a vertical fixing assembly and a horizontal fixing assembly, wherein the wood board encloses a pouring area; the vertical fixing assembly is arranged on the outer side of the wood board and comprises vertically arranged vertical pipes with first through holes; the horizontal fixing assembly is arranged on the outer side of the vertical fixing assembly and comprises horizontally arranged horizontal pipes with second through holes; the opposite pulling fixation assembly comprises a screw rod and a bolt, and the screw rod passes through the first through holes, the second through holes and the wood board and is fixed by the bolt; and the vertical pipes and the horizontal pipes comprise steel pipes and concrete filled in the steel pipes.

[0006] Compared with the wooden shuttering, the vertical pipe and the horizontal pipe of the utility model comprise a steel pipe and concrete filled in the steel pipe, firstly, the steel pipe provides good compression resistance and tensile resistance, and the concrete can effectively resist impact and deformation, therefore, the pipe body of the steel pipe-concrete structure has higher bearing capacity and structural stability than the wooden shuttering, can bear greater concrete pouring pressure, can effectively prevent deformation of the formwork in the pouring process, and ensures accuracy of the pouring shape. Secondly, the steel pipe can adopt hot galvanizing, anti-corrosion coating or stainless steel material, can resist weather changes (such as high temperature, low temperature, humidity, etc.), especially has strong corrosion resistance in humid or severe environment, has long service life, and can be recycled; the wooden shuttering is greatly affected by environmental humidity and temperature change, is prone to damp, rot or be eroded by pests, and can need frequent replacement and maintenance in long-term use. It can be seen that the pipe body of the steel pipe-concrete structure of the formwork of the utility model has obvious advantages in structural strength, stability, service life, construction efficiency, safety and environmental protection compared with the wooden shuttering, especially in large-scale and complex structure construction, the steel pipe-concrete formwork can provide higher bearing capacity, impact resistance and longer service life, reduces dependence on wood resources, and meets the environmental protection demand of the modern building industry.

[0007] As a further improvement of the above concrete pouring formwork: the steel pipe is a square steel pipe. Thus, the price is cheap, it is easy to obtain, and it is convenient to use.

[0008] As a further improvement of the above concrete pouring formwork: the square steel pipe has a cross-sectional side length of 30-50mm. Thus, the filled concrete amount is appropriate, the construction and carrying cost caused by excessive self-weight of the pipe body is not increased, and the bearing capacity and impact resistance caused by excessive small self-weight cannot be ensured.

[0009] As a further improvement of the above concrete pouring formwork: the arrangement spacing of the vertical pipe is 50-150mm. Thus, the formwork self-weight is adapted, and the supporting effect is good.

[0010] As a further improvement of the above concrete pouring formwork: the arrangement spacing of the horizontal pipe is 200-400mm. Thus, the formwork self-weight is adapted, and the supporting effect is good.

[0011] As a further improvement of the above concrete pouring formwork: the concrete filled in the steel pipe is C20 fine stone concrete. The C20 fine stone concrete refers to concrete with a strength of C20 and a maximum particle size of coarse aggregate of not more than 15mm, and thus the obtained pipe body has higher impact resistance.

[0012] As a further improvement of the above concrete pouring formwork: the vertical pipe and the horizontal pipe are spliced by the short section and the sleeve. Thus, according to the pouring volume of the wall column, the pipe body of the corresponding size can be assembled for use, the resource utilization rate is improved, and the material cost is reduced; the splicing through the sleeve is not only convenient to operate, but also has high strength, high bearing capacity and high impact resistance.

[0013] As a further improvement of the above concrete pouring formwork: the length of the sleeve is 30-60 mm. Thus, the operation is convenient, and the strength of the connection is high.
