Abstract

The utility model relates to a novel multi-layer wooden fire door, which solves the technical shortcomings in the prior art that the sizes of perlite blocks need to be strictly controlled according to requirements, once the sizes are inaccurately controlled, gaps can be caused to be too big or can not be encased, the installation difficulty is big, which is time-consuming and labor-consuming and the like. The novel multi-layer wooden fire door comprises a framework, whose two sides are respectively provided with panels, and a fire-proof plate is arranged between the framework and the panel, and a hollow cavity is surrounded by the panels and the framework. The novel multi-layer wooden fire door is characterized in that integral type perlite bodies which are formed by perlite particles and adhesive through pressing are filled in the hollow cavity. Compared with the prior art, the novel multi-layer wooden fire door has the advantages that firstly, the novel multi-layer wooden fire door has simple shaping technique and low cost, does not have the problem of dissonant sizes, and is time-saving and labor-saving, secondly, the combination of the perlite bodies and other structures of the fire-proof door is closed, which can effectively improve the integral quality, thirdly, the novel multi-layer wooden fire door has excellent fire-proof, smoke-proof, heat-proof, flame-proof and sound-proof properties.

Description

The novel multi-layer fire-proof wooden door

Technical field

The utility model relates to the labeled door technical field, especially relates to a kind of novel multi-layer fire-proof wooden door.

Background technology

Fire-proof wooden door adopts high-quality timber, handles by fire protection flame retarding and makes, and is filled with in door leaf and the corresponding high-quality fire-proof heat-insulating material of labeled door fire resistance rating.Generally select for use perlite as inserts.Fire-proof wooden door also has advantages such as in light weight, good seal performance, conduction of heat and thermal deformation are little, fire-proof and thermal-insulation, outward appearance elegance, decoration convenience except possessing common timber good performance and result of use.Be applicable to public civilian and industrial construction with civilian construction and various fire protection requirements such as high residential building, hotel, restaurant, cinema, sports palace, library, hospital.

At present, the perlite of fire-proof wooden door all is filled into inner later on by cutting into block.For example, Chinese patent literature discloses a kind of composite door core [application number: CN94205056.8], it is characterized in that: be made of wooden frame, composite material paste, glass fiber, expanded perlite; Wooden frame is " Lu " font, is the tabula bar in the middle of it; Be to add one deck expanded perlite and the sheet material that forms in the wooden frame by two-layer composite material paste, layer glass fiber, centre.The shortcoming of this structure is, perlite block needs as required controlling dimension strictly, in case the inaccurate space of will causing of size Control is excessive or can't pack into, installation difficulty is big, wastes time and energy.In addition, other structures of perlite block and labeled door combine also defective tightness, cause the quality of labeled door to be difficult to improve.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and a kind of processing and manufacturing that is easy to is provided, the structural strength height, and combining of other structures of pearl rock mass and labeled door is tight, can effectively promote the novel multi-layer fire-proof wooden door of overall quality.

For achieving the above object, the utility model has adopted following technical proposal: this novel multi-layer fire-proof wooden door, comprise skeleton, be respectively equipped with a panel in the both sides of skeleton, between skeleton and panel, be provided with PLASTIC LAMINATED, above-mentioned panel and skeleton surround cavity, it is characterized in that, are filled with the integral type pearl rock mass that is formed by compacting by perlite particle and adhesive in the described cavity.

Because adopt integral type pearl rock mass, the utility model is processed very convenient, only perlite particle that need stir and adhesive etc. are put into cavity, suppress promptly plastic then.After the moulding, the perlite body can closely contact with various piece fully, does not have the size problem of disharmony.

In above-mentioned novel multi-layer fire-proof wooden door, described PLASTIC LAMINATED comprises some plates, and described plate is fixed on the skeleton, and part protrudes in skeleton, the ledge formation step of described pearl rock mass and plate.

PLASTIC LAMINATED is not an integral structure, but is made up of some fire prevention plates that are separately fixed on the skeleton, and the fire prevention plate segment protrudes in skeleton.This structure not only helps saving the consumption of PLASTIC LAMINATED, also can not reduce the structural strength and the fireproof performance of labeled door simultaneously; And step can make pearl rock mass and fire prevention plate closely cooperate fully.

In above-mentioned novel multi-layer fire-proof wooden door, described panel is made by three-ply board; Described skeleton is made by solid wood.Skeleton here and three-ply board are handled through fire protection flame retarding, therefore have stronger fireproof performance.

In above-mentioned novel multi-layer fire-proof wooden door, the length of described plate ledge is 3mm～7mm.

Compared with prior art, the advantage of this novel multi-layer fire-proof wooden door is: 1, moulding process is simple, and is cheap, do not have the size problem of disharmony, time saving and energy saving.2, other structures of pearl rock mass and labeled door combine closely, can effectively promote overall quality.3, have good fire prevention, Smoke prevention, heat insulation, fire-retardant, sound insulation value.

Among the figure, skeleton 1, panel 2, PLASTIC LAMINATED 3, plate 31, cavity 4, pearl rock mass 5, step 51.

The specific embodiment

As shown in Figure 1, the novel multi-layer fire-proof wooden door comprises skeleton 1, is respectively equipped with a panel 2 in the both sides of skeleton 1, is provided with PLASTIC LAMINATED 3 between skeleton 1 and panel 2, and above-mentioned panel 2 surrounds cavity 4 with skeleton 1.Panel 2 is made by three-ply board; Described skeleton 1 is made by solid wood.Skeleton 1 here and panel 2 are handled through fire protection flame retarding, therefore have stronger fireproof performance.

Be filled with the integral type pearl rock mass 5 that forms by compacting by perlite particle and adhesive in the cavity 4.Because adopt integral type pearl rock mass, the utility model is processed very convenient, only perlite particle that need stir and adhesive etc. are put into cavity, suppress promptly plastic then.After the moulding, the perlite body can closely contact with various piece fully, does not have the size problem of disharmony.

PLASTIC LAMINATED 3 comprises some plates 31, and described plate 31 is fixed on the skeleton 1, and part protrudes in skeleton 1, the ledge formation step 51 of described pearl rock mass 5 and plate 31.The length of plate 31 ledges is 5mm.PLASTIC LAMINATED is not an integral structure, but is made up of some fire prevention plates that are separately fixed on the skeleton, and the fire prevention plate segment protrudes in skeleton.This structure not only helps saving the consumption of PLASTIC LAMINATED, also can not reduce the structural strength and the fireproof performance of labeled door simultaneously; And step can make pearl rock mass and fire prevention plate closely cooperate fully.

Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.

Although this paper has used terms such as skeleton 1, panel 2, PLASTIC LAMINATED 3, plate 31, cavity 4, pearl rock mass 5, step 51 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
