Description

Anti-cracking component structure of door and window corner wall (8)

The present invention relates to an anti-cracking component structure for the corner walls of doors and windows, in particular to a structure that can completely disperse and absorb the seismic stress transmitted to the corners of the door and window frame, so as to effectively prevent the wall structure, the ridges and the joints of the corners of the door and the window frame. The anti-cracking component structure of the door and window corner wall surface with micro-cracking phenomenon such as the surface paint layer.

According to, in order to maintain indoor ventilation and lighting, the walls of existing buildings will be equipped with windows. When the building expands and shrinks due to heat or is shaken by an earthquake, it is easy to crack at the corners of the window frame of the wall, causing rain. Infiltrate the room from the cracks. Therefore, the inventor of this case developed the "Window Corner Structure Wall Crack Prevention Element" of Taiwan Announcement No. I650468. Please also refer to Figure 10. The window corner structure wall crack prevention element (8) is integrally formed with a One piece part (81) and a second piece part (82) vertically connected to 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 in the holes (83) of the first piece (81) and the second piece (82), a positioning rod (84) is inserted, thereby, the crack prevention element (8) of the window corner structure wall Installed at the corners of the formwork window frame (A), and then fixed on the formwork with positioning rods (84), and then set steel bars around the formwork window frame (A), and then concrete grouting is carried out to fix the wall surface of the window corner structure The anti-cracking element (8) is wrapped in the wall. Here, when the building is subjected to vibration and shaking, and stress is generated at the corner of the formwork window frame (A), the stress system can be obtained by the anti-cracking element on the wall of the window corner structure (8) Absorption to achieve the effect of avoiding wall cracks at the corners of the formwork window frame (A).

Of course, please also refer to Figure 11. The wall anti-cracking element (8) of the window corner structure of Taiwan Bulletin No. I650468 is installed on the formwork window frame (A), and then along the formwork window frame (A). When installing the steel bar (B), the construction personnel must climb to a high place with the ladder frame to pass the steel bar (B) from top to bottom through the crack prevention element (8) of the window corner structure and its first section ( 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 inventor of this case further developed the "Door and Window Corner Wall Anti-crack Assembly Structure" of Taiwan Case No. 108126855, which is the fifth-generation product developed by the inventor. Please also refer to Figure 12 for this door and window. The corner wall surface anti-cracking component structure (9) is mainly connected with two phases at the side of the gap (913) of the first piece (911) and the second piece (912) of the anti-cracking element (91). A positioning hole (914) is provided adjacent to the fixed rod (92), and the working area defined by the plurality of fixed rods (92) together is provided with a positioning hole (914). After the positioning hole (914) penetrates the setting rod (93), the anti-cracking element (91) The nails are installed at the corners of the formwork door frame or formwork window frame (A). When the reinforcement (B) is installed along the formwork door and window frame (A), the reinforcement (B) can be placed directly Insert the anti-cracking element (91) into the steel bar rest area (94) formed between the outer side of the first piece (911) and the second piece (912) of the anti-cracking element (91) and the adjacent fixing rod (92), and place the steel (B) Lean against the fixed rod (92) of the steel bar placement section (94) to achieve the rapid completion of the steel bar (B) installation and improve the efficiency of on-site construction.

When the grouting concrete is solidified to form a wall structure (C), the formwork can be removed with a door and window frame (A) to form a reserved door and window on the wall structure (C) for formal Install with a door frame or a formal window frame (D). After the door and window frame (D) are assembled, the door and window frame (D) and the wall structure (C) reserved for the door and window will be connected If a void is generated, cement mortar must be used to fill the void to form a gap (E) after the void is filled. Of course, the Taiwan Announcement No. I650468 "Window corner structure wall surface crack prevention element" and Taiwan Case No. 108126855 "Door and window corner wall surface crack prevention component structure" are mainly covered in the wall structure (C), by Although its setting can absorb the seismic stress transmitted to the corners of the door and window frame (D) to prevent large cracks in the wall structure (C) at the corners of the door and window frame (D), it still cannot be transmitted to the The seismic stress at the corners of the door and window frame (D) is completely dispersed and absorbed, so that the wall structure (C) and the surface stucco layer at the corner of the door and window frame (D) will still have micro cracks. In addition, because the Taiwan Announcement No. I650468 "Window corner structure wall surface crack prevention element" and Taiwan case No. 108126855 "Door and window corner wall surface crack prevention component structure" are not designed to be reinforced at the corner (E). Therefore, when the seismic stress is transferred to the ridge (E), the ridge (E) and the whitewashed surface are prone to cracks (as shown in Figure 13).

The reason is that the inventors used the previously developed Taiwanese Bulletin No. I650468 "Window corner structure wall anti-crack component" and Taiwan case No. 108126855 "Door and window corner wall anti-crack component structure".
