Description

A kind of compound enhancing floor

The utility model discloses the compound enhancing floor of a kind of flooring finishing usefulness.

Existing wood flooring mainly is wood lath (piece) solid wood products, lays the plank piece splicing mainly be divided into nail shop behind the first frame wood a tree, used in making timber for boats keel and have tongue-and-groove by building glue and ground bonding.Its shortcoming is a construction trouble, and consumptive material is many, and the floor makes moist for a long time can be rotten, take off nail or warpage.

In recent years, for saving timber, convenient construction improved purposes such as quality, and existing people proposes wood flooring compound structure and new consolidation method.All proposed the stratiform compound structure as China's patent 94215964.0,94208398.9,93226086.1,93218332.8 and application number 90223227.4,90225866.4, China's patent 93223711.8,92238633.1 and 92200737.3 all similarly proposes fluting slip-type floor board block with convenient splicing to reach saving high-quality timber effect.2L93229602.5 then propose the block structure of a kind of reassembling type compoiste wood floor.But owing to reasons such as material therefors, nearly all be unable to undergo the immersion of water, the floor be installed still quite bother.

The purpose of this utility model is to make the compound enhancing of a kind of lamination floor, keep the peculiar fitting-up effect of wooden floor, but interlayer can not absolved after being subjected to water logging or being subjected to moisture, can not be out of shape yet.Without the frame keel,, and can remove when mating formation also without organic adhesion agent.

For realizing the utility model purpose, the surface of composite floor board is that (5～7mm) constitute, and lower floor is the composite material that is made of thermosetting resin/chopped fibres/filler by the hard veneer of handling through hydrophobic in advance on the upper strata.The upper and lower are superimposed together by adding certain pressure, and upper and lower interlayer also has mechanical connection simultaneously.Sidewall has horizontal groove around the lower floor, and horizontal groove is used for inserting the long and narrow bar shaped steel of embedding and transplants a cutting, and it is whole that adjacent floor is overlapped to form a flat board mutually by cutting.Steel is transplanted a cutting can be fastening by self-tapping screw and ground, thereby the floor also can be followed with ground.In addition, lower floor's bottom embedding just can make floor and ordinary Portland cement ground bonding with granular silicate mineral if spread cement in the lower floor bottom.If the floor only uses screw and ground fastening, can remove in the future.

Now elaborate in conjunction with the accompanying drawings:

Fig. 1. be the schematic appearance on the compound enhancing of the utility model floor.

Fig. 2. be the complex method and the paving method schematic diagram on the compound enhancing of the utility model floor.

Fig. 11 selects for use thickness 5～7mm through the chemically treated veneer of hydrophobic at the middle and upper levels, all be drilled with symmetrical blind hole two veneer adjacent side, can inject thin bamboo reinforcement 4 in the aperture, with a diameter less than 0.2mm steel wire 5 one ends bundle jail on thin bamboo reinforcement, the other end is fastened (see figure 3) on below the wire gauze 6.Should notice that thin bamboo reinforcement 4 should accomplish tight fit as far as possible when injecting side opening, firmly when piecing together, (because steel wire is very thin, timber is softer simultaneously in the not influence that coincide almost of 5 pairs of pieces of finer wire for adjacent like this two planks.)

Fig. 2 at the middle and upper levels 1 and lower floor 2 combination interface places should have adhesive strength, and make upper strata 1 and lower floor's 2 pressings with certain pressure, do not interspace at the interface.Since the steel wire 5 of enhancing system part and wire gauze 6 be bury solid in the matrix of lower floor 2, so the adhesion of upper and lower layer is that hinge is strong.

Lower floor 2 bottom surfaces evenly have been covered with silicate mineral particle 3.Because to tie up to resin be the micelle shape that is soft when uncured to the composite bodies of lower floor 2 during Manufacture of Floor, the mineral particle can partly be inlayed in lower floor's 2 matrixes, treat that the mineral particle is the bottom surface of embedding jail in lower floor 2 behind the resin solidification of lower floor 2, thereby make lower floor 2 bottom surfaces and ordinary Portland cement have cementability.

The bottom of the floor sidewall horizontal groove of Fig. 1 has gap 7, and gap 7 is used for holding self-tapping screw 10.Earlier steel is drawn together in the groove that a side that does not have the hole on the bar 9 injects floorboard when mating formation and is gone, steel transplant a cutting in addition-side porose 8; Plastics expand tube 11 (as Fig. 2) are placed after making a call to a hole in ground below hole 8 in the hole, with a countersunk head screw 10 (matching) with the aperture steel is drawn together bar 9 and ground fastening, to keep steel to transplant a cutting 9 and the sidewall notches horizontal level that exists together when attacking tight screw 10, then carrying out behind the gap 7 position alignment screws 10 of another floor to piecing together, just make steel transplant a cutting 9 another but groove is advanced in intercalation, should notice that gap 7 spacings on the sidewall of floor should transplant a cutting that hole 8 spacings equate on 9 with steel.

If do not use screw fastening, can be not open and clear mouthfuls 7, utilize the cementability of silicate granulosa 3 and cement, after spreading cement in ground or bottom surface, floor, adjacent floor board block is transplanted a cutting overlap joint to piecing together by steel, can finish the fastening of whole floors and ground, guarantees that simultaneously the floor surface splicing is smooth.If ground is not too smooth, as far as possible with cementitious, if ground is smooth, the screw fastening floor also can be used in both available cementitious floor.

Be easy to see,, only with opening floorboard, just can unclamp other screw, thereby whole floors can be removed in the future if only fix the floor with screw.

The utility model is compared with existing technology and has the following advantages:

(1) floor surface can be combined into multiple patterns, has kept the fitting-up of solid wooden floor board Effect, but save timber consumption 2/3～1/2 than solid wooden floor board.

(2) the mentioned patent laminate of existing wood floors and bed specification beginning is multiple Closing the floor nearly all can not soaking-resistant. And composite strengthened floor of the present utility model can be water-fast Immersion reaches can be because water be out of shape, because the veneer on upper strata, floor is in advance through hydrophobic chemistry place Reason, and lower floor's composite does not have water imbibition, moisture can not by subsurface material thoroughly to upper, Lower floor's combination interface has the combination after pressurizeing of levels junction firm again, adds at the interface in addition Mechanical connection function is arranged, so under the impact of external force or external environment (such as water), the floor still Can be very firm.

(3) the existing wood floors back side often is coated with organic gel, makes itself and ground bonding, also needs first frame rough ground as the ground injustice.Major defect is that organic gel is with the passing of time aging easily, with rough ground construction trouble.And this floor can be bonding with cement and ground, like this can be without organic adhesion agent and rough ground, and it is easier to mat formation.
