Description

Composite board filling structure for fireproof door pocket

Technical Field

The utility model relates to a door pocket especially relates to a composite sheet filling structure for preventing fire door pocket.

Background

As is well known, a fire door can effectively control the fire when a fire breaks out, and is very important for the safety of life and property of people. The conventional fireproof door pocket filling materials have the following defects: the steel filler, the fireproof glass filler and the glass magnesium board filler have the problem of higher cost, and most common buildings are difficult to use except individual high-grade buildings, especially individual poor areas; the traditional wooden fireproof plate adopts wood which is not easy to burn, and is soaked by using solutions of cations such as calcium and aluminum and anions such as phosphate radical and silicate radical, so that the fireproof performance is achieved, and the cost is still high; and the fireproof gypsum board, the fireproof cotton board and the like are used as fillers, so that the strength is low, and the fillers cannot bear strong explosion impact.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a simple structure, with very low costs, impact resistance force's a composite sheet filling structure for fire door pocket in order to overcome prior art not enough.

The specific technical scheme is as follows: the utility model provides a composite sheet filling structure for fire door pocket bonds with solid board by the multiply wood of interval arrangement in proper order and forms the lamellar structure, totally 2-7 layers, the multiply wood for the whole board of multiply wood or form by the concatenation of a plurality of multilayer strip, solid board for the whole board of wood or form by the concatenation of many solid wood strips, adjacent panel bonds or the staggered joint bonds perpendicularly, horizontal adjacent panel passes through adhesive linkage I and bonds, vertical adjacent panel passes through adhesive linkage II and bonds, vertical adjacent panel passes through adhesive linkage III and bonds.

The multilayer board and the solid board are all made of recycled waste boards.

From the technical scheme of the utility model can see out, this simple structure bonds multiply wood and solid board cross arrangement fissure of displacement or perpendicular bonding to externally the bonding go up the PLASTIC LAMINATED can.

This structure is used for preventing fire door pocket's inside main part filling structure, has following benefit: 1. compared with the traditional pure steel filling structure, a glass magnesium board door pocket, a fireproof wood door pocket and other structures, the process is simpler, the production cost is greatly reduced, the production cost of the traditional wooden fireproof door filling structure is 150 yuan per square meter, the raw materials of the structure are prepared by recycling building waste three residues, the production cost is about 40-50 yuan per square meter, the cost is reduced by more than 60%, and the fireproof door is more easily accepted by consumers; 2. the structure adopts the staggered joint bonding of the multilayer board and the solid board, the bonding is firm, and the layer separation is not easy to occur; 3. the wood grain mechanism of the log is broken through, so that the board has better elasticity, the impact force can be reduced to a certain extent through elastic deformation under strong impact, the elasticity is good, the reduction is easy, and the practicability is strong; 4. in the aspect of wooden fire door pocket is filled, the multiply wood has that moisture resistance is strong, is difficult for the moisture absorption inflation deformation, characteristics that structural stability is good, and solid wood board has good heat preservation, thermal-insulated, syllable-dividing effect to and stronger rigidity effect, consequently this structure will adopt the scheme that multiply wood and solid wood board spliced each other and formed, possess heat preservation, thermal-insulated, syllable-dividing effect, and the advantage is obvious in the aspect of the comprehensive properties of stability and impact resistance.

Through many times of experiments, the fireproof door cover that this structure set up is non-deformable under humid environment, and stability is strong, and elasticity limit is big, compressive strength, impact toughness, hardness all are good, and comprehensive properties is good, and the practicality is strong. In addition, the cost is low, and the market value is better. Therefore, the invention completely realizes the aims of simple structure, low cost and strong impact resistance under the condition of meeting the basic fireproof function.
