Abstract

The utility model relates to an anti-stripping plywood. An entire board containing adhesive between each basic material single board is provided with a connecting object mechanically ligated. The utility model uses bamboo and wood as basic boards. The utility model not only uses the adhesive to conduct the adhesion between layers but also uses the strength and the toughness of metal nails, wires, non-metal wires and other connecting objects. The entire boards in a laminated layer shape of the bamboo and the wood basic boards are mechanically ligated together and are made into an integral board by high temperature and high pressure. The plywood has good entire performance and high strength and can be widely used for an instant pouring mould board of building cement.

Description

The antistripping glued board

The utility model relates to the glued board of a kind of building industry with material, especially a kind of antistripping glued board.It can be widely used in the cast-in-place template of building building cement.

At present, building trade is generally made the cast-in-place template of cement with glued board, and this glued board is with two-layer above bamboo matter or wood substrate and interlayer connects with the binding agent knot and through the one plate of HTHP moulding.Though it is easy to use, cheap, exist after cement mortar immersion, vibrating head vibration poor, the easily layering of peel strength, the shortcoming that service life is short.

The purpose of this utility model is intended to overcome the weak point of above-mentioned glued board, provides that a kind of antistripping, intensity are good, not stratified, the antistripping glued board of long service life.

The purpose of this utility model is to realize like this: have between base material that binding agent knot connects and through the one plate of HTHP moulding.Contain between its every base material veneer on the integral slab that binding agent is layer structure and also have the attachment of pricking knot with machinery.

Described attachment is that the metal Ma Ding, the bundle that are the spike of stapling together are tied on integral slab, and its horse nail is crooked later equal with plate.

Described attachment is wire, makes and prick knot on integral slab.

Described attachment is non-metal wire (silk), makes and prick knot on integral slab.

Available metal Ma Ding, wire, anticorrosion non-metal wire are wherein a kind of on integral slab, and perhaps wherein two kinds, perhaps three kinds as the antistripping attachment.

The base material veneer is bamboo matter veneer or Wooden veneer.The layer structure of two above base material veneers can be integral slab or the integral slab of Wooden veneer lay-up or the integral slab of bamboo matter veneer and Wooden veneer mixing lay-up of bamboo matter veneer lay-up.

Bamboo matter veneer be bamboo mat, bamboo curtain splint, bamboo chip wherein any one, perhaps wherein any two, perhaps three kinds combination.

The utility model has utilized the intensity and the toughness of peg, silk and non-metal wire dexterously, with mechanical system the lay-up laminated integrally plate of bamboo and wood base material veneer is pricked knot together, carry out ply adhesion with binding agent simultaneously, make its plate that becomes one through HTHP, the glued board overall performance is good, intensity is high, has realized the purpose of this utility model fully.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a kind of floor map of the present utility model.

Fig. 2 is a kind of structural representation of A-A (vertically) section of Fig. 1.Attachment 2 among this figure is metal Ma Ding.

Fig. 3 is the another kind of structural representation of A-A (vertically) section of Fig. 1.Attachment 2 among this figure is wire (or non-metal wire).

Fig. 4-Figure 10 is respectively a floor map of the present utility model.

Referring to Fig. 1, Fig. 2, Fig. 3: this glued board is the integral slab that is made of the tool layer structure bamboo mat (or with bamboo curtain splint, bamboo chip, veneer) for two veneers 1 (also claiming substrate) and the attachment 2 metal Ma Ding (or adding wire or anticorrosive line again) of base material.Coat or be soaked with binding agent on its base material veneer 1, its overlapping being laid in is integral slab together, with attachment 2 metal Ma Ding its integral slab being pricked with machinery and tied (the metal Ma Ding that resembles the staple shape vertically being pressed into or injecting integral slab and horse is followed closely crooked later equal with the backboard face), is the one plate through the HTHP compacted under then.

Connect thing 2 with wire (or anticorrosive non-metal wire), should resemble sewing machine footwear repairs press proof wire or anticorrosive line are penetrated on the integral slab.

The antistripping glued board of different-thickness: with metal horse pinning knot, adopt the metal Ma Ding of different model, guarantee fund's nail of being born in the year of horse is injected formula and is pressed into and becomes rectangle (longitudinal section of one plate) to exceed in the integral slab; Prick knot with intensity height, good toughness, etch-proof silk (line), should be sewn into similar circle (longitudinal section of one plate).

The processing method of this antistripping glued board following (remove step 3, other is prior art):

(1): will be coated with gluing or soak gluing on bamboo mat (or bamboo curtain splint or bamboo chip or veneer etc.) base material after drying.

(2): be laid in together to the integral slab of desired thickness (bamboo curtain splint, bamboo chip, veneer should intersect in length and breadth lay) the bamboo mat more than two or two of gluing or impregnation (or bamboo curtain splint or bamboo chip or veneer etc.) substrate 1 is overlapping.

(3): select attachment 2 to prick knot for metal Ma Ding and intensity height, good toughness, etch-proof silk (line) carry out machinery to step (2), pricking the knot mode is two kinds: one, metal Ma Ding vertically is pressed into or inject in the integral slab and make its crooked turn one's head smooth with the backboard face; Two, similar sewing machine footwear repairs press proof penetrates silk or line in the integral slab.

(4): to the good sheet material of the pricking knot 18-60kg/cm that heats (110-150 ℃), pressurizes ²), make its curing molding.

The substrate stratiform integral slab of this glued board is pricked knot with machinery, adopt metal Ma Ding, wire, non-metal wire is wherein a kind of, perhaps wherein two kinds, perhaps three kinds as antistripping attachment 2, this attachment 2 is pricked knot on integral slab, (referring to Fig. 4-Figure 10): the attachment 2 as Fig. 4 is " well " font can to constitute various plane patterns, attachment 2 as Fig. 6 is " triangle " shape, attachment 2 as Fig. 5 is " rice " font, attachment 2 as Fig. 8 is " bar " font, it is quincunx to be " ten " word as the attachment 2 of Figure 10, is " plum blossom " stake shape as the attachment 2 of Fig. 9, is " rib " font as the attachment 2 of Fig. 7.

The peel strength of this antistripping glued board is relevant with the density of bonding agent and mechanical connection, requires peel strength higher, and the glued board of longer service life can be selected high binding agent of adhesion strength and the density that increases mechanical connection for use.Prick knot once on every square decimeter with metal Ma Ding 1m * 2m * 0.005m specification, with 10 * 10, the antistripping glued board that connects into the intersecting parallels of Fig. 4 is made the cast-in-place template of cement.It is than stack pile, same specification, same base material, only high by 1% with the glued board manufacturing cost of binding agent, but access times can increase 50-60%, the use cost 49-58% that can descend.
