Background

The reinforced concrete structure consists of reinforcing steel bars and concrete, and the concrete is poured into a building template in which a reinforcing cage is placed in a flowing plastic state and then is cured and molded. The commonly used building templates comprise three types, namely steel templates, steel-wood templates and wood templates. The steel template has high rigidity, good performance and can be repeatedly used, but the cost of one-time investment is high. The common wood formwork has small rigidity, low repeatable utilization rate and easy water absorption. The quality of the concrete structure is affected by the curing conditions, and a certain humidity is maintained during curing. Because the common wood formwork has water absorption, if the common wood formwork is maintained improperly, the quality of concrete is easily influenced, and the concrete is easily cracked due to plastic shrinkage at the early stage.

The clear water template is one of building templates, and the template is a glued wood template which is generally formed by taking plates such as birch, poplar, pine, fir, eucalyptus and the like as base materials and impregnating the surfaces of the plates with phenolic resin with strong waterproofness through high-temperature hot pressing. The clear water template has the obvious characteristics compared with the common building template, has light weight, large breadth and no warping, but the surface coating of the template is easy to age and fall off to reduce the waterproof effect and cannot be exposed to the sun. In order to solve these problems, the utility model 'a waterproof plywood' (CN 205395328U) proposes to paste a PVC layer on the common wood board for waterproof. The construction of the patent is required to be carried out on a professional machine, and the PVC material has the problems of easy aging and insufficient hardness.

Based on foretell material characteristic and the problem that exists, the utility model discloses special design out a compound building templates of easily constructing, ability separation moisture to solve the above-mentioned problem.
