Fig. 6-1 is a perspective view of another U-type reinforcement frame with three-dimension in accordance with looking window structure in the fireproof door of the prevent invention. - In view of the product on the market of the design in the patents, all of them are not taken into consideration of the production line for the requirements of the production forthright, convenient in installation and building, structure strength and the usage of said fireproof door in match with the environment.
- The present invention relates to an improvement in them and provides a production forthright, the circumference of looking window casement installed a U-type reinforced board to reinforce the strength of the board of fireproof door, the hollow between said casement and board of door is filled with fireproof filler, without using the screw to lock together and being able to assemble the looking window of a fireproof door rapidly. The performance is illustrated as follows:
- The present invention relates to a structure for a looking window casement of a fireproof door, having a
fireproof door 1,U-type reinforcement sheet 5 withfixed pin 4, and a lookingwindow frame 2 clamped withglass sheet 3. Thefireproof door 1 has a cutting open place for lookingwindow installing space 11,U-type reinforcement sheet 5 with thefixed pin 4 is fixed into thefireproof core material 11 between a mezzanine offireproof door 1 at the proper place of the circumference,female sheet 20 of looking window frame havingfemale button 203 to be placed on the cutting open place for lookingwindow installing space 11 andmale sheet 21 of looking window frame havingmale button 213 clasped each other. -
Fig. 1 is a partially enlarged view of three-dimension in accordance with looking window structure in the fireproof door of the prevent invention. Thefireproof door board 12 of thefireproof door 1 is installed withcoarctation forming surface 200 of lookingwindow frame 2 at a suitable place. Theglass sheet 3 of looking window is clamped between the lookingwindow 2. -
Fig. 2 is an explosive view of three-dimension in accordance with looking window structure in the fireproof door of the prevent invention.

Saidcoarctation forming surface 200 is able to form the ornament on the plastic material in advance, and then forming on the surface of thefemale sheet 20 and themale sheet 21 of lookingwindow frame 2. Further, it also is able to form the ornament on the plastic material first, then to form three-dimensional protruding ornament and then to pressure them on the surface of thefemale sheet 20 and themale sheet 21 of lookingwindow frame 2. - The inner side of
female sheet 20 hasfemale button 203, also the inner side ofmale sheet 21 hasmale button 213. While installing the looking window frame casement, the inner part of the circumference of thefemale sheet 20 painting with thefireproof glue 6 and fireproof material with thermal expansion of graphite substance, the expansion strip is simultaneously installed into the circumference of the lookingwindow installing space 11, then after thefemale sheet 20 painted withfireproof glue 6 is stuffed into the lookingwindow installing space 11, theglass sheet 3 is placed on thefemale sheet 20, and then the inner part of the circumference of themale sheet 21 among the glass sheet, looking window frame and core material painting with the fireproof glue and fireproof material with thermal expansion of graphite substance, from the another side offireproof door 1 to stuff into the lookingwindow installing space 11, finally themale button 213 ofmale sheet 21 andfemale button 203 offemale sheet 20 fasten each other and fixed on thefireproof door 1. - The top of
female sheet 20 having a topfemale sheet 204 and the top ofmale sheet 21 having a top male sheet 214 (referring toFig. 3 ) are able to let the fixedpin 4 be bared in the shelter of the surface of thefireproof door 1. Their bottom part also has bottomfemale sheet 205 and bottommale sheet 215 respectively. Theglass sheet 3 is placed in their center. The circumferences of both sides of glass sheet are infilled with sealed fixingglue 7, and then said looking window frame is fixed on thefireproof door 1. - Under the processing, it is not to lock by using the screw to reach simple and quick processing method. Further, after completion of processing, there is no any nail-head and the head of fixed screw to be bared so as to harm the appearance.
-
Fig. 4 is perspective view of the looking window frame with double glass sheets in accordance with looking window structure in the fireproof door of the prevent invention. The circumference of space between the double glass sheets is installed with space block to separate said glass sheets and fastened with sealed fixing glue. The other procedure of the processing method is identical with those of the single glass sheet. - Please refer to
Fig. 6 , in case thefireproof core material 10 is a hardenable material of inorganic fireproof material such as calcium silicate board, pearl board (foam board), magnesia board, etc, it needs larger force to place theU-type reinforcement sheet 5 in. The front part of both sides in theU-type reinforcement sheet 5 is cut and punched intoserration arrangement 51 with row pattern to convenienceU-type reinforcement sheet 5 to be installed intofireproof core material 10. Further, it is able to cut and to punch the both sides of theU-type reinforcement sheet 5 havingU-type reinforcement groove 52, then the top parts of the both sides ofU-type reinforcement sheet 5 are cut into the shape of thefront tip part 53 so that saidU-type reinforcement sheet 5 is placed intofireproof core material 10 formed with hardenable material more easily. - The above
female sheet 20 and themale sheet 21 of lookingwindow frame 2, under installation processing, are able to use fireproof tape instead of fireproof glue. - Since certain changes may be made in the above described invention without departing from the spirit and scope of as the invention herein involved, it is intended that all of the subject matter of the above description or shown in the accompanying drawings shall be interpreted merely as examples illustrating the inventive concept herein and shall not be construed as limiting the invention.
