Description

Door and window corner wall anti-cracking component structure (8)

This creation is about a door and window corner wall anti-cracking component structure, especially one that can completely disperse and absorb the seismic stress transmitted to the door and window frame corners, so as to effectively prevent the door wall and window frame corner wall structures, cracks and their The anti-cracking component structure of the door and window corner wall surface where the micro-cracking phenomenon occurs on the surface painting layer.

In order to maintain indoor ventilation and light illumination, windows are installed on the walls of existing buildings. When the building expands or contracts due to thermal expansion or vibration, it is prone to cracks in the corners of the window frames of the wall, resulting in rain. Infiltrated into the room by cracks. Therefore, the author of this case developed the "Window Corner Structure Wall Crack Prevention Element" of Taiwan Announcement No. I650468. Please also refer to the tenth figure. The window corner structure wall crack prevention element (8) is integrally formed with a first One piece part (81) and a second piece part (82) vertically connecting the first piece part (81), the first piece part (81) and the second piece part (82) are provided with a plurality of holes (83) , And a positioning rod (84) is pierced in the holes (83) of the first piece (81) and the second piece (82), by which the window corner structure wall anti-cracking element (8) is formed Installed at the corner of the formwork window frame (A), and then fixed to the formwork with the positioning rod (84) nails, followed by setting reinforcement around the formwork window frame (A), and then performing concrete grouting to the window corner structure wall The anti-cracking element (8) is wrapped in the wall. Here, when the building is subjected to vibration, etc., and stress is generated at the corner of the formwork window frame (A), the stress can be obtained by the anti-cracking element of the wall structure of the window corner. (8) Absorb to avoid cracking of the wall in the corner of formwork window frame (A).

Of course, please also refer to the eleventh picture. The Taiwan corner No. I650468 window corner structure wall crack prevention element (8) is installed on the formwork window frame (A), and then along the formwork window frame (A) When installing the reinforcement (B), the construction personnel must climb to a high place by the ladder frame to pass the reinforcement (B) from the top to the bottom through the window corner structure wall crack prevention element (8) the first part ( 81) The gap formed between the two positioning rods (84) at the end, and this construction process is extremely time-consuming and labor-intensive, which reduces the efficiency of on-site construction. Therefore, the creator of this case further developed the "Crack-proof Structure of Door and Window Corner Wall Surface" of Taiwan Case No. 108126855, which is the fifth-generation product developed by the creator of this case. Please also refer to the twelfth figure for the doors and windows. The corner wall anti-cracking component structure (9) is mainly provided with two phases fixed on the side of the gap (913) of the first piece (911) and the second piece (912) of the crack prevention element (91) Adjacent to the fixing rod (92), the positioning interval (914) is defined in the working interval formed by the plurality of fixing rods (92), after the positioning hole (914) passes through the setting rod (93), the anti-cracking element (91) The nail is installed at the corner of the formwork door frame or formwork window frame (A) frame. When the reinforcement bar (B) is installed along the formwork door and window frame (A), the reinforcement bar (B) can be placed directly Into the anti-cracking element (91) between the first piece (911) and the second piece (912) of the outer edge and the adjacent fixed rod (92) formed between the reinforcement bar (94), and the reinforcement (B) Abut against the fixed rod (92) of the steel bar resting area (94) to achieve the rapid completion of the installation of the steel bar (B) to improve the efficiency of on-site construction efficiency.

After the grouting concrete solidifies to form the wall structure (C), the form can be removed with the door and window frame (A) to form a reserved door and window for the wall structure (C) for formal With door frame or formal window frame (D) installation, when the door and window frame (D) are assembled, there will be a meeting between the door, window frame (D) and the door and window reserved for the wall structure (C) A void is generated, and the gap must be filled with cement mortar to form a crack (E) after the gap is filled. However, the Taiwan Bulletin No. I650468 "Window Corner Structure Wall Crack Prevention Element" and Taiwan Case No. 108126855 "Door Window Corner Wall Crack Prevention Component Structure" are mainly wrapped in the wall structure (C), by Although its setting can transfer the seismic stress to the corner of the door and window frame (D) to prevent the wall structure (C) at the corner of the door and window frame (D) from cracking, it still cannot be transferred to the The seismic stress at the corner of the door and window frame (D) is completely dispersed and absorbed, so that the wall structure (C) at the corner of the door and window frame (D) and the surface paint layer will still have micro cracks. In addition, the Taiwan Bulletin No. I650468 "Window Corner Structure Wall Crack Prevention Element" and Taiwan Case No. 108126855 "Door Window Corner Wall Crack Prevention Component Structure" are not designed to reinforce the crack (E) at the design Therefore, when the seismic stress is transmitted to the bevel (E), the bevel (E) and its painted surface layer are prone to cracking (as shown in Figure 13).
