Detailed Description

The present invention will be described with reference to specific embodiments.

Fig. 1 is the cross sectional view of fire prevention paper face gypsum board, as shown in fig. 1, fire prevention paper face gypsum board includes: go up gypsum board 1, the concatenation is fixed lower gypsum board 2, the fixing of going up 1 bottoms of gypsum board go up 1 and the fireproof cotton 3 between the gypsum board 2 down. An upper runner 11 is arranged on the bottom surface of the upper gypsum board 1, and a lower runner 21 corresponding to the upper runner 11 is arranged on the top surface of the lower gypsum board 2. A plurality of heat dissipation channels 22 are arranged in the lower gypsum board 2 at equal intervals, and the heat dissipation channels 22 are communicated with the outside atmosphere. A plurality of communication holes 23 distributed in an array are arranged between the heat dissipation channel 22 and the lower flow channel 21. The fireproof cotton 3 is positioned between the upper flow passage 11 and the lower flow passage 21.

Fig. 2 is a view showing the bottom surface of an upper gypsum board, and fig. 3 is a view showing the top surface of a lower gypsum board, and as shown in fig. 2 and 3, the upper and

lower runners

11 and 21 are formed in an elliptical raceway shape and include a plurality of raceway groups which are connected to each other. Adopt last gypsum board 1 that the concatenation formed and gypsum board 2 down, utilize mosaic structure to promote the whole thickness of plate and not influenced in order to guarantee the bearing capacity originally, utilize mosaic structure to install fireproof cotton 3 and set up other fireproof structure in the middle of it simultaneously.

The device is provided with an upper flow passage 11 and a lower flow passage 21 for heat dissipation, and the tortuous runway shape is adopted to furthest increase the area of the flow passages in a limited space so as to increase the parts participating in heat dissipation and enlarge the heat dissipation area. The lower gypsum board 2 is internally provided with the heat dissipation channel, so that the lower gypsum board 2 has small load bearing requirement, and the influence on the load bearing is small when the lower gypsum board 2 is arranged; secondly, in order to lead out the hot air in the upper runner 11 and the lower runner 21 through the heat dissipation channel 22, the air circulation inside the plate is enhanced. The fireproof cotton 3 that sets up between upper and lower runner, fireproof cotton 3 generally are fiber construction, still play the isolated and exclusion effect to the ignition material in the circulation of air when the circulation of air.

As shown in fig. 1 and 3, the top of the lower gypsum board 2 is further provided with a support structure 24, and the fireproof cotton 3 is fixed on the support structure 24. The support structure 24 comprises: a plurality of central brackets 241 disposed between the lower runners 21, and edge bracket sets 242 disposed at both sides of the lower runners 21. The central support 241 comprises a single support and the edge support group 242 comprises a plurality of supports. The support structure 24 is provided for supporting the fireproof cotton 3 so as to facilitate installation and taking of the fireproof cotton 3, and also provides a space for circulation of hot air to be dissipated. The edge bracket set 242 serves the primary support function and thus includes a plurality of brackets, with the central bracket 241 serving both support and provide structural rigidity.

The communication holes 23 are plural and arranged in an array in the linear flow path portion of the lower flow path 21. The curved tracks are located at the edge positions, and the heat dissipation channels 22 are not arranged at the corresponding positions for the bearing strength of the plate.

Go up the bottom both ends of gypsum board 1 and be equipped with mounting groove 12, the top both ends of gypsum board 2 are equipped with installation piece 25 down. The mounting block 25 is correspondingly mounted in the mounting groove 12. This arrangement serves to aid in positioning during installation and forms a channel in the mounting block 25 for installation of the fire wool 3, construction of the flow channel, and systematic heat dissipation.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
