Abstract
The utility model relates to a connecting piece for a formaldehyde-free composite floor. The utility model is characterized in that the connecting end surfaces of an A floor (1) and a B floor (1) are respectively provided with a left and a right grooves corresponding to the connecting piece (2), the connecting piece is embedded in the left and the right grooves from left and right, and the structural shape of the connecting piece (2) forms a T shape or a cross shape. The utility model has the advantages that the connecting piece between composite floors made of formaldehyde-free base material can effectively solve defects that connection between composite floors made of formaldehyde-free base material is unreliable, the strength between connection can not reach operating requirements. The utility model has the characteristics of reliable connection between composite floors and convenient operation. The utility model increases the strength between two connecting composite floors, ensures the safety performance of the composite floor made of formaldehyde-free base material and provides effective measures for popularization and application of the composite floor made of formaldehyde-free base material.
Description
Technical field
The utility model relates to a kind of connector,, belong to interior decoration and use pavement attachment technique field as the connection between the composite floor board of making by formaldehydeless base material.
Background technology
The composite floor board that the formaldehydeless base material of a kind of usefulness is made, the problem that this floor does not only exist formaldehyde to discharge, and static bending intensity 〉=40.0MPa, thickness swelling rate≤2.5%.Its structure adopts four layers of overall structure, and the top layer is a wearing layer, and the second layer is that decorative layer, the 3rd layer are substrate layer, and bottom is a balance layer.Substrate layer adopts stalk high density fiberboard, the density 〉=0.80g/cm of stalk high density fiberboard
3Four interlayers are bonded into an integral body with the melamine bonding adhesive with four layers by the dipping that does not contain formaldehyde.Its advantage is because the substrate layer material therefor is to be bonding adhesive with formaldehydeless isocyanates, thereby greatly reduce base material formaldehyde burst size (≤0.1mg/100g), make the floor material of main part not have aldehyde release, thereby reach the purpose of whole pavement low burst size of methanal.The problem that this floor does not only exist formaldehyde to discharge, and static bending intensity 〉=40.0MPa, thickness swelling rate≤2.5%.Suitable bonding adhesive can satisfy the gummed of surface layer abrasion-proof layer, bottom balance layer and substrate layer.What finish that connection between two composite floor boards often adopts is that connection end face place between two composite floor boards has tongue-and-groove respectively and makes tenon, during use with tongue-and-groove and the organic combination of tenon, thereby finish connection between two composite floor boards.Yet this connection has following defective: promptly the switching performance between two composite floor boards is poor, and is unreliable, and the intensity between connection does not often reach instructions for use.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of connector, as the connection between the composite floor board of being made by formaldehydeless base material, technical solution of the present utility model: the T-shaped or cross of connector planform.
Advantage of the present utility model: as the connector between the composite floor board of being made by formaldehydeless base material, the connection that can effectively solve between the composite floor board of being made by formaldehydeless base material is unreliable, and the intensity between connection can not reach the defective of instructions for use.The connection that has between composite floor board is reliable, characteristics easy to use, improved the intensity between two composite floor boards connect widely, guaranteed to use the security performance of the composite floor board of making by formaldehydeless base material, for the composite floor board of applying by formaldehydeless base material manufacturing provides effective measures.
Accompanying drawing 2 is that the utility model structure is criss-cross user mode schematic diagram
Among the figure 1 is the floor, the 2nd, and connector.
The specific embodiment
The contrast accompanying drawing, its structure is the T-shaped or crosss of connector 2 planforms.
During use, have respectively and connector 2 corresponding left and right grooves with the end face place that is connected on B floor 1 on A floor 1, in the left and right groove that connector 2 left and right embeddings are above-mentioned.The embedding end of connector 2 is spherical in shape, and two composite plates connect the back and work the effect of locking, and improve the reliability that connects.The material available metal or the plastic production of connector 2.Effectively guarantee the intensity between the connection of two composite floor boards, improved reliability, the safety of using the composite floor board of making by formaldehydeless base material,
Claims (2)
1, uses connector between formaldehydeless composite floor board, it is characterized in that having respectively and the corresponding left and right groove of connector (2) with the end face place that is connected of B floor (1) in A floor (1), in the above-mentioned left and right groove of the left and right embedding of connector (2), the T-shaped or cross of planform of connector (2).
2, use connector between formaldehydeless composite floor board according to claim 1, it is characterized in that the embedding end of connector (2) is spherical in shape.
