Advantages of Hollow plastic Building template

Date of release:2019-04-22 Author: Click:

1. The bearing capacity of plastic building template is low. 

At present, the plastic building template is mainly used as the roof and floor template, the bearing capacity is low, as long as the spacing of secondary beams can meet the construction requirements. 

However, to be used as a wall post template, it must be processed into a steel frame plastic template. 

Therefore, the formula of plastic building template should be adjusted, the production process should be improved, the performance of plastic building template should be improved, and the GMT template should be developed at the same time. 

2, the strength and stiffness of plastic building template is too small. 

The static bending strength and static elastic modulus of plastic building template are smaller than other template. The strength and stiffness of plastic building template used in China is lower than that of bamboo (wood) template and much lower than that of foreign GMT template.

3. Welding slag is easy to burn plastic building template. 

At present, the plastic template is mainly used as the floor template. When laying steel bar, the welding slag temperature is very high when the steel bar is connected, which falls on the plastic template and is easy to burn the plate surface. 

It affects the surface quality of molded concrete. 

Therefore, flame retardants can be added to polypropylene to improve the flame retardancy of plastic templates. 

In addition, protective measures can be taken during the welding operation, such as sending a piece of stone cotton cloth to the welder, tiling the plane template under the solder joint, and leaning a small plank next to the solder joint for the erecting template. 

The problem of welding hot plastic building template can be solved. 

4. Large thermal expansion and cold shrinkage coefficient of plastic building template. 

The thermal expansion and cold shrinkage coefficient of plastic building template is large, and the thermal expansion and cold shrinkage coefficient of plastic board is larger than that of iron and steel and wood, so plastic building template is greatly affected by temperature, such as summer high temperature period, the temperature difference between day and night is up to 40 ℃, according to the data, at high temperature, 

The expansion of the 3 m long plate can reach 3 mm and 4 mm. 

If the slab is constructed at night, the arch will occur in the middle of the template by noon; if the slab is laid at noon, the shrinkage of the template at night will cause the gap between the adjacent plates to produce 3mm~4mm. 

In order to solve the problem of large expansion, the expansion coefficient can be reduced by adjusting the material formula and improving the processing technology. 

In addition, in the construction, we can choose an average temperature time to lay the slab, or seal the sponge strip between the plate and the board, which can eliminate the gap between the template, ensure that the concrete does not leak, and solve the problem of arch at high temperature.
