Abstract

The utility model belongs to a door for buildings, which is mainly formed by a wood frame, a wood layer board and a wood lath lattice positioned between the frame and the layer board through agglutination and heat pressure. The door has the advantages of material saving, light weight, low cost, high strength, difficult deformation, good moisture-proof performance and flat and smooth appearance, and is an ideal door for buildings.

Description

Framework composite hollow door

The utility model belongs to a kind of Door for building.

China's Door for building adopts wood frame hollow core flush door form more, and it at first makes a type framework with timber, covers with three ply board, flakeboard or cardboard to form in the stickfast of framework both sides again.This door is hollow in the place that does not have frame supported, and intensity is very poor, and this kind door frame materials are many simultaneously, and about about 0.07 square metre with timber at every fan door reduces the framework material, then easily produces problems such as not firm distortion.For overcoming the defective of traditional hollow core flush door, the hollow core flush door of several forms has appearred again in the market: the one, and with the inserts of crops straw particle glue mixing as hollow part, but this kind door intensity is also little high, is afraid of to make moist; The 2nd, mix with bamboo wood particle and to put into the moulding of hollow mould HTHP behind the urine aldehyde glue and make the composite hollow door, though that it has solved is yielding, the defective of intensity difference, but still have that materials are many, heavy, moisture resistance is not ideal and shortcoming such as making up paint; The 3rd, the bamboo wood composite hollow door of our factory invention last year, as the hollow part inserts, this door has solved problems such as joint material, intensity, weight, distortion preferably with thick bamboo tube, but does not reach optimal degree yet at aspects such as materials, weight and costs.

The purpose of this utility model is to provide a kind of materials minimum, and intensity is enough, and not yielding, weight is lighter, and the Door for building that cost is minimum is to satisfy the demand of builing industry.

The wooden lath grid that the framework composite hollow door that the utility model provides is mainly made by wood frame, wooden laminate and leftover pieces is through gummed hot pressing composite molding.Wooden laminate is positioned at the wood frame both sides, and the hollow part between wood frame and wooden laminate is being placed wooden lath grid, to strengthen the intensity of hollow part.

The utility model is owing to adopt thinner batten to make wood frame, and the wooden lath grid made from waste material supports hollow part, and whole through the HTHP glue molding, so that it has material-saving, weight is light especially, and the advantage that cost is minimum.Door type with 1944 * 716 * 38mm is an example, and every fan door is 0.02 cubic metre of materials only, and weight has only 9.6kg, and cost is 65% of a conventional door, and this door has intensity height, not yielding, the advantage that smooth in appearance is attractive in appearance and humidity resistance is good.

Now the utility model is further described in conjunction with Figure of description.

Fig. 1 is the formation schematic diagram of a kind of concrete structure of the utility model.

Fig. 2 is wooden lath grid structure schematic diagram.

As shown in the figure, the utility model is by wood frame (1), wooden laminate (2), and wooden lath grid (3) and short batten (4) constitute.With house door 0824 is example, wood frame (1) adopts the straight batten of 1944 * 40 * 35mm and the ledger strip of 716 * 50 * 35mm to make 1944 * 716 * 35mm door type framework, the short batten (4) of 300 * a 100 * 35mm is set in the framework inboard, is used to install door lock and handle.Wooden lath grid (3) constitutes grid structure as shown in Figure 2 with becoming the wide batten of 35mm under the layer of wood board waste material by 7-9 root vertical bar 5-6 root horizontal stripe.Wooden lath grid (3) is put in the framework of wood frame (1), its length direction two ends are embedded on the wood frame ledger strip, again the laminate (three ply board) (2) of two 1944 * 716mm is used the glue bond of urine aldehyde in the doorframe both sides, put into hot press thermal synthesis framework composite hollow door.

Claims

1, a kind of through gluing together hot-forming framework composite hollow door, comprise wood frame and be positioned at the wooden laminate of two sides, it is characterized in that between wood frame and two wooden laminates, being provided with wooden lath grid.

2, framework composite hollow door as claimed in claim 1 is characterized in that wooden lath grid makes grid structure by wooden laminate waste material, and its length direction two ends are embedded on the wood frame ledger strip, and are filled with in wood frame.
