Abstract

The utility model relates to a novel wood door leaf structure, which is characterized in that the utility model is composed of a wooden frame, a gluing board and a pasting board. The framework of the wooden frame is made of raw wood having a small diameter, the middle lock part of the wooden frame is provided with a reinforcing rib, and a transverse beam is arranged. The gluing board is spliced by wooden bars, and the wooden frame is stuck with the pasting board. The utility model has the advantages of low requirement on the diameter class of the raw wood, material saving, full use of waste materials at rim angles and little waste, strength and impact resistance are enhanced, the disadvantages of the existing wood doors are overcome, and compared with plywood door leaves, the utility model has low cost and favorable development foreground.

Description

Plywood door

The utility model relates to a kind of novel timber page structure.

At present, the wooden construction door leaf of civilian construction and middle-size and small-size industrial premises and accessory building has two kinds both at home and abroad: a kind of structure is the timber page or leaf of wooden frame veneering, and a kind of is the veneer door leaf of rubberizing plywood on the wooden frame.The characteristics of these two kinds of door leafs all are to take timber, and log is directly had relatively high expectations, and promptly need the log footpath at least more than 110mm, and want the timber page or leaf owing to inlay with plank, be subject to climatic effect and distortion, crack occur, not only the pass is closed and is affected, and influences attractive in appearance.Though the veneer door leaf is not subjected to the influence of climate, because the two sides all is a veneer, the cost height.In the processing of timber, can produce leftover pieces such as many feather edge boardings, short wood,, can only dispose, waste very big as waste material owing to can't be used.

The purpose of this utility model just provides a kind of novel timber page or leaf, and is not only less demanding to former size class, and can make full use of leftover pieces, and cost is low, saves timber, and the intensity of door leaf, anti-impact force are also than existing door leaf improve.

Solution of the present utility model is: be made of wooden frame, splicing plate and pasting board, wherein the structure of wooden frame is to have groove up and down in the framework inboard of being made by flitch, on the framework between the groove crossbeam is being housed up and down, on the framework at middle part reinforcing rib is being housed between the groove up and down, the splicing plate is to become plate or splicing plate to be docking together by the batten splicing to constitute again, two blocks of splicing plates are inserted into respectively in the groove up and down of wooden frame, and the joint of splicing plate places on the crossbeam, in the wooden frame between two blocks of splicing plates filler can be arranged, post pasting board respectively on the two sides of wooden frame.

Detailed content of the present utility model further describes as follows referring to accompanying drawing:

In technique scheme, the flitch of formation framework can be selected for use than the log of minor diameter and make, like this, because former size class is required not quite can make full use of some waste and old woods.Because it is less to constitute the flitch size of framework, in order to guarantee reliably to install securely lock, reinforcing rib (7) is housed at the middle part of framework, splicing plate (2) can be formed or is docking together after flush by short batten splicing again by the long stuff splicing, can be that one deck batten is combined into also can be that the multilayer batten is combined into, and can make full use of leftover bits like this, strengthen door leaf intensity, joint places on the crossbeam of framework, avoids butt joint to disconnect, and plays reinforcement effect.Filler can be arranged in the wooden frame (1) between two blocks of splicing plates (2), can be used for strengthening the intensity of timber page or leaf, post pasting board (3) respectively, make the outward appearance of door leaf clean and tidy, beautiful on the two sides of wooden frame (1).

Feature of the present utility model also be to be filled with in the wooden frame (1) between two blocks of splicing plates (2) can and splicing plate (2) between short wooden (4) of gummed, like this, whole door leaf composes an integral body by the wooden frame (1) of periphery and middle filler promptly short wooden (4), and its intensity and anti-impact force all improve greatly than existing timber page or leaf.Post one, two or polylith pasting board (3) respectively on wooden frame (1) two sides, to select for use as required.Of the present utility model all be to adopt phenol glue or urea-formaldehyde glue hot pressing to form in conjunction with the contact position, in conjunction with firm, globality is strong.

The laminated wood door leaf that the utility model provides has the following advantages: (1) can make full use of used timber and the remaining leftover bits of Wood Processing, turns waste into wealth, and cuts the waste.(2) the utility model is less demanding to former size class, and making existing door leaf need be with the log diameter minimum more than 110mm, and the utility model only to need diameter be that the log of 60mm is just passable.(3) lacking than existing timber that door leaf consumes, is example with one 810 * 1950 door leaf, and processing one the three bucket timber page or leaf volume of timber is 0.04m ³, the veneer door leaf volume of timber is 0.03m ³And maximum 0.02m of the utility model ³(4) respectively adopt phenol glue or urea-formaldehyde glue hot pressing to form in conjunction with the contact position owing to of the present utility model, globality is strong, so intensity and anti-impact force all improve than existing wooden page.(5) because two sides of the present utility model hot pressing has lamina, and its cost is lower than veneer door leaf, overcome the timber page or leaf simultaneously again and be subject to the climate influence and the defective of deformation crack, therefore the utlity model has very, vast market is worth.

Concrete structure of the present utility model is provided by drawings and Examples.

At first accompanying drawing is described.

Fig. 1 represents the STRUCTURE DECOMPOSITION figure of door leaf;

Fig. 2 represents the sectional drawing of door leaf.

According to embodiment shown in the drawings, the utility model is by wooden frame (1), splicing plate (2) and pasting board (3) constitute, wherein wooden frame (1) is to be made of two long flitches and the short flitch of the six roots of sensation, the planing surface up and down of two long flitches and two short flitches has two grooves (5), its specifications section is 50～70 * 41mm, form framework, make the framework medial surface of formation form two annular grooves up and down, two short flitches are crossbeam (6) in addition, on the framework about being horizontally installed in the middle of the groove (5), two short flitches are reinforcing rib (7), on the long flitch about being vertically installed in the middle part of groove (5) central frame, specifications section is 50～70 * 34, splicing plate (2) is to become behind the plate three blocks of plates to be docking together by short batten splicing to constitute again, two blocks of splicing plates (2) are inserted into respectively in the annular groove up and down of framework, joint is just placed on the crossbeam (6), be filled with short wooden (4) of irregular alignment in the wooden frame (1) between two blocks of splicing plates (2), short wooden (4) two ends and two veneers (2) are glued together, post two blocks of pasting boards (3) respectively on wooden frame (1) two sides, all adopt phenol glue or urea-formaldehyde glue hot pressing to form in conjunction with the contact position.
