Description

Mounting structure of stereoplasm WPC and soft PVC composite board

Technical Field

The utility model relates to the technical field of composite boards, in particular to a mounting structure of a hard WPC (wood-plastic composite) and soft PVC (polyvinyl chloride) composite board.

Background

WPC is made up of polyethylene, polypropylene and polyvinyl chloride through mixing with more than 50% of wood powder, rice husk and straw to obtain new wood material, and extruding out, shaping and injection moulding to obtain plate or shaped material. The method is mainly used in industries such as building materials, furniture, logistics packaging and the like.

The wood-plastic composite material contains plastics and fibers. Therefore, they have processability similar to wood. They can be sawed, nailed and planed. The nail can be completed by adopting a woodworking tool, and the nail force is obviously superior to that of other synthetic materials. The mechanical properties are superior to wood. Nail force is typically three times that of wood and five times that of particle board.

The wood-plastic composite material contains plastics, so that the wood-plastic composite material has a better elastic modulus. In addition, due to the inclusion of the fiber and the full mixing with the plastic, the wood has the same physical and mechanical properties with hardwood, such as compression resistance, bending resistance and the like, and the durability of the wood is obviously superior to that of common wood. The surface hardness is high, typically 2 to 5 times that of wood.

For the wood-plastic composite floor of concatenation formula, it contains one or more concatenation unit, and every concatenation unit includes the basic unit, and one side of basic unit is equipped with the lug, and its opposite side is equipped with the recess with lug complex, and the lug surface of basic unit one side is equipped with the constant head tank, the recess internal surface is equipped with the setpoint of being connected with the constant head tank cooperation. During installation, the lug in one splicing unit is matched with the groove in the other splicing unit, and after splicing is finished, the end faces of the two adjacent splicing units are attached. For the structure, because the end surfaces of the two adjacent splicing units are attached together after splicing, although the expansion rate of the wood-plastic composite floor when being heated or the shrinkage rate of the wood-plastic composite floor when being cooled are smaller, after the two end surfaces are attached together, no yielding space is provided between the two adjacent splicing units for the expansion after being heated, and therefore the adjacent splicing units are arched.

In addition, when the wood-plastic composite floor is installed in the prior art, the keel is usually installed on the foundation firstly, and then the wood-plastic composite floor is fixed on the keel through the pressing plate and the screws, so that the installation mode is not only troublesome, but also has high cost. And because the hardness of the contact part of the wood-plastic composite floor and the keel is higher, when a user walks on the wood-plastic composite floor, no buffering feeling exists, and the noise caused by impact force is also higher during walking.
