Background

In the field of construction, a batten keel is widely used in the process of template manufacturing and installation as an indispensable object. Due to the huge demand of the flitch keel, the limited forest resources are gradually reduced. The novel product capable of replacing the traditional batten keel becomes the development direction of the batten keel in the building industry, and the existing steel pipe structure and the novel material glass fiber reinforced plastic product have obvious defects. The steel pipe structure keel is not widely applied due to the characteristics of high cost, easy corrosion and rust, inconvenience for template installation and the like; the keel of the new material glass fiber reinforced plastic product contains glass fiber, so that workers are easy to cause allergy and uncomfortable body when using the keel, and the keel is not widely used, is processed again by utilizing an old wood template, realizes the reutilization of resources, and can achieve the purposes of energy conservation and environmental protection.

The composite batten keel in the prior art adopts a composite reinforcing material, and although higher strength is ensured, the toughness is poorer and the integrity is poorer; the corners and edges are clear, so that the corners and edges are easy to collide and damage, stress defects are generated, and the corners and edges are also influenced by the processing precision and are not beneficial to stacking and transportation.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an improved composite batten keel, which solves the problems in the prior art, promotes the recycling of waste wood and reduces the environmental pollution; has the advantages of high strength, portability, practicability, low cost, difficult corrosion, safety, environmental protection and long service life; through the non-woven fabrics, toughness and wholeness have been improved, and is not fragile.

In order to achieve the above purpose, the utility model provides a following technical scheme: an improved composite batten keel comprises battens, wherein each batten comprises a plurality of layers of battens, and adjacent battens are bonded through a first adhesive layer; the outer side of the batten is coated with non-woven fabric, and the non-woven fabric is bonded with the batten through a second adhesive layer; the outside of the wood beam is coated with a plastic layer, and the interior of the plastic layer is added with reinforced fibers.

Further, the first adhesive layer is hot melt adhesive or thermosetting adhesive.

Further, the plastic layer is polypropylene, polyethylene or pet polyester resin.

Further, the reinforcing fibers are glass fibers.

Further, the reinforcing fibers are of an interwoven mesh structure.

Furthermore, the outer edges of the plastic layers are all provided with round corners.

The beneficial effects of the utility model are as follows:

the utility model promotes the recycling of waste wood and reduces the environmental pollution; the plastic layer with the reinforced fibers is adopted for wrapping, so that the plastic plate has the advantages of high strength, portability, practicability, low cost, corrosion resistance, water resistance, wear resistance, safety, environmental protection and long service life; due to the arrangement of the non-woven fabric, the toughness of the keel and the integrity of the batten are improved, and the batten is prevented from loosening; the outer edges are provided with fillets, so that local collision damage is reduced, and the steel wire rope is not easy to damage; the outward appearance is regular, avoids stacking the clearance, is convenient for stack the transportation.
