Plastic building template is a kind of temporary model structure to ensure the pouring of concrete according to the requirements of structural design. It has to bear the horizontal load and vertical load produced in the process of structural construction.
It is an important construction tool in the construction of concrete structure, plastic building template.
In the cast-in-place concrete structure project, the cost of the template project generally accounts for about 5% of the cost, and the construction time accounts for about 50% of the construction period.
Therefore, the selection of template is directly related to construction cost, construction speed and engineering quality.
Pvc plastic template today gives you a brief introduction:
1. Summary of the development of building template.
Before the reform and opening up, the construction of our country is mainly brick-concrete structure, and the traditional wood template is basically used in the construction.
The commonly used composite steel template and wood plywood template began to be used in the construction process on a large scale only in 1978. Since then, with the support of the national policy of "replacing wood with steel", the composite steel template has been popularized rapidly and occupied half of the template market.
Since then, the traditional wood template and steel template have been gradually replaced by wood plywood.
With the rapid development of industrial and agricultural production in China, the annual consumption of wood is very amazing.
2. Disadvantages of traditional architectural template.
Wood plywood template has always occupied most of the construction template market with the advantage of low price.
According to the calculation that 1 cubic meter of wood plywood needs to consume 2.53 cubic meters of log, China needs to cut down at least 16 million trees with a diameter of 30 centimeters every year in order to meet the needs of the current construction wood template market.
However, China is a country with a relative shortage of wood resources in the world, the forest coverage rate is only 3. 5% of the world average level, and the per capita forest area is less than 1. 4% of the world average level, and because the turnover of wood template is less and the loss is fast,
The growth rate of trees is slow. Since the national policy of banning the felling of natural forests in 1998, the production template of wood resources provided by artificial forests alone has been unable to meet the market demand.
Moreover, the high demand for wood resources caused by wood template not only caused the damage to the natural environment, but also ran counter to the idea of green construction.
The turnover times of composite steel template is high, although it can be repaired and reused, but the surface size of commonly used composite steel template is small and there are many joints, so it is difficult to apply to the construction of large area fair-faced concrete.
In addition, the steel template is of large quality, consumes a lot of manpower and material resources in the construction, the plate surface is easy to rust, the cleaning workload is large, the maintenance is difficult, there are many kinds of accessories used in the construction, there are many auxiliary working hours, and it is easy to wear and tear in the course of use, which leads to the increase of amortization cost.
Because of the advantages of large format, high strength, wear resistance, smooth surface, easy demoulding, fast demoulding, smooth concrete surface, high repeated utilization rate, low cost and so on, bamboo glue board template also has a place in the template market.
However, bamboo plywood has high requirements for production technology and construction. Once the bonding strength is not enough, it is easy to open glue and damage and reduce the repeated utilization rate.
As each bamboo glue board factory is to prepare their own adhesive, it is difficult to ensure the stability of its quality.
If the surface treatment is not meticulous during construction, it is easy to leave bamboo mats on the concrete surface after demoulding.
If the type of glue used in film coating is not appropriate, it will damage the surface of concrete.
3. Characteristics of plastic template.
The energy consumption in the production and application of building plastic template is much lower than that of other materials, which is only 1 to 5 of steel and 1 to 8 of aluminum mold.
Therefore, the promotion and application of plastic template in the template market is an important measure to "replace wood with plastic", save resources and save energy consumption.
Therefore, the new plastic template, which can greatly reduce the cost, has become an important application in building template.
Plastic template to scrap plastic template return and waste plastic as the main raw materials, the proportion of testing, crushing and adding flame retardant, high temperature resistance, cold resistance, impact resistance, bending resistance materials, in the molten state through the injection molding process.
Plastic template handling, labor saving, low labor intensity, and can be used more than 30 times, scrapped after all can be recovered, and then made by the manufacturer into a new template.
