Abstract

A composite material building batten sequentially comprises a wood chip, a resin inner layer, a continuous fiber composite felt and a resin outer layer from inside to outside, the wood chip or a template is used as a substrate, a pultrusion process is adopted to wrap a resin layer and the continuous fiber composite felt layer on the surface of the wood chip or the template, and the problems that the surface of a traditional batten is not smooth, has burrs, damages a concrete layer and cannot be reused are solved; the building batten production line has high automation degree and high yield, and is suitable for large-scale production.

Description

Composite material building batten

Technical Field

The utility model relates to a building field relates to a combined material building flitch.

Background

The existing preparation process of building battens mainly comprises the steps of independently coating a layer of glass fiber composite felt on the outer surface of each batten, and pouring resin among the battens, so that a plurality of battens coated with the glass fiber composite felt are sequentially bonded together to serve as a batten body. Then covering a layer of glass fiber composite felt on the upper surface and the lower surface of the batten, simultaneously pouring resin and enabling the resin to permeate the glass fiber composite felt, then conveying the batten into a curing bin, and obtaining the batten of which the surface is covered with high-strength and high-waterproof glass fiber reinforced plastic after the resin and the glass fiber composite felt are completely cured, wherein the batten is widely applied to cast-in-place concrete structure engineering construction in the building field.

However, there are many problems with this method: the production process is complex, each link is not connected, and time and labor are wasted; the building batten obtained by the method has unsmooth surface, so that the surface of the concrete poured and formed is uneven, the aesthetic degree is influenced, and time and labor are consumed for secondary repair; meanwhile, the wood boards are bonded by resin instead of being integrally formed, and under the action of concrete fluidity or gravity, the concrete can extrude surrounding building battens, so that the battens are misplaced and damaged, the glass fiber composite felt is easy to expose, and the hands of workers are scratched or allergy is caused.

Disclosure of Invention

The utility model aims at providing a combined material building flitch has the advantage that the structure is succinct, the surface is smooth.

The composite material building batten sequentially comprises a wood chip, an inner resin layer, a continuous fiber composite felt and an outer resin layer from inside to outside, wherein the outer surface of the outer resin layer is smooth and has no burrs.

Preferably, the wood chips are multi-layer wood chips or monolithic wood boards.

According to the invention, a plurality of layers of wood chips are stacked and coated with covering resin, then the continuous fiber composite felt is wrapped on the surface of the inner layer of the resin, and the resin is immersed, then the continuous fiber composite felt is stretched, cured and compacted on the surface, so that the building batten is smooth and has no burrs, and the obtained building batten has a smooth surface.
