Description
Technical Field
[0001] This invention relates to the technical field of building components, and more particularly to a crack-resistant component structure for door and window corner walls. Background Technology
[0002] Existing buildings typically have windows installed in their walls. When buildings experience thermal expansion and contraction or are shaken by earthquakes, cracks easily form at the corners of the window frames, allowing rainwater to seep into the interior. Therefore, to improve the crack resistance of the wall structure at the corners of door and window frames and prevent wall cracks or micro-cracks from occurring under earthquakes or other external forces, the inventors of this case have sequentially developed the following door and window corner wall crack prevention component structures: "Window Corner Structure Wall Crack Prevention Component" (Publication No. TWI650468B), "Window Corner Wall Crack Prevention Component Fixing Structure" (Publication No. TWM582057U), "Door and Window Corner Wall Crack Prevention Component Structure" (Publication No. TWI695106B), "Door and Window Corner Wall Crack Prevention Component Structure (VI)" (Publication No. TWM594053U), and "Door and Window Corner Wall Crack Prevention Component Structure (VII)" (Publication No. TWM592012U).
[0003] After installation, the aforementioned anti-crack component structure for door and window corners will form a pre-reserved door or window in the wall structure. When the door or window frame is installed in the door or window, the resulting gap will be filled with cement mortar to form a recessed joint. However, when seismic stress is transmitted to the recessed joint, micro-cracks are prone to occur in the recessed joint and its surface plaster layer. Therefore, the inventors of this case have developed a "Crack-Preventing Component Structure for Door and Window Corner Walls (VIII)" with publication number TWI708882B. Please refer to [link / reference]. Figure 7 As shown, the anti-crack component structure m of the door and window corner wall mainly consists of multiple anti-crack components m1 arranged at intervals, which are fixedly connected by a fixing rod m2. A reinforcement unit m3 has two reinforcement plates m31 connected to the two ends of the fixing rod m2 respectively, and a shock-absorbing component m32 is provided between the two reinforcement plates m31. Each of the two reinforcement plates m31 has a recessed reinforcement part m33 formed. Thus, when the anti-crack component structure of the door and window corner wall is installed and used, its recessed reinforcement part m33 can be combined with the recessed joints at the corners of the door and window frames. By using the recessed reinforcement part m33 of the reinforcement unit m3, the crack resistance of the wall structure and the recessed joints at the corners of the door and window frames can be improved, so as to protect the recessed joints and plaster layer at the corners of the door and window frames from micro-cracks during earthquakes.
[0004] Therefore, as can be seen from the above-mentioned research and development process of the inventors in this case, the inventors have used their products in practice and continuously discovered areas for improvement, striving to make their products more user-friendly and practical. Although the "Door and Window Corner Wall Crack Prevention Component Structure (Eight)" previously developed by the inventors with the publication number TWI708882B has already achieved the effect of improving the crack resistance of the wall structure and recesses at the corners of door and window frames by setting its reinforcement unit m3, its reinforcement unit m3 is mainly composed of two reinforcement plates m31 and a shock-absorbing component m32. Not only is the manufacturing cost high, but the shock-absorbing component m32 must be spot-welded to the notches of multiple crack prevention components m1 when assembling with the crack prevention component m1. In addition, the two reinforcement plates m31 must also be fixed by passing through the ends of multiple fixing rods m2 of the crack prevention component m1. Therefore, there are still inconveniences in assembly and use, and it is not ideal. Therefore, the inventors, with the concept of continuous improvement, developed this invention to make their products more perfect. Summary of the Invention
[0005] This invention relates to a door and window corner wall anti-crack component structure, mainly targeting the "Door and Window Corner Wall Anti-crack Component Structure (VIII)" with announcement number TWI708882B. Its main purpose is to provide a door and window corner wall anti-crack component structure that is simple in structure, low in manufacturing cost, convenient to install, and can effectively prevent micro-cracks from occurring in the wall structure at the corners of door and window frames.
[0006] To achieve the aforementioned objectives, the inventors have devised the following anti-crack component structure for door and window corner walls. This structure primarily involves multiple spaced anti-crack components fixedly connected by a fixing rod. At least one side of the notch in each anti-crack component is connected to a resistance plate corresponding to the shape of the notch. This resistance plate increases the gripping area and bonding stability with the wall structure at the corner of the door or window frame, thereby improving the crack resistance at the stress-bearing front end of the wall structure at the corner of the door or window frame. When stress generated by earthquakes or other factors is transmitted to the resistance plate, it is blocked, changing the direction of stress transmission and creating resistance to external forces. This reduces and disperses the effect of external forces on the stress end, thereby improving the stress resistance and crack resistance performance at the stress-bearing front end of the wall structure at the corner of the door or window frame. This effectively protects the surface layer at the stress-bearing front end of the wall structure at the corner of the door or window frame from cracking or micro-cracking during earthquakes or other stressors.

[0038] First, please refer to Figure 1 As shown, the anti-crack component structure for door and window corner walls of the present invention mainly includes:
[0039] Multiple anti-crack components 1 are arranged to correspond to each other and are spaced apart in front and behind. Each anti-crack component 1 includes a first piece 11 arranged longitudinally and a second piece 12 arranged laterally. The first piece 11 and the second piece 12 are vertically connected to form an L-shape. The first piece 11 and the second piece 12 together form an L-shaped notch 13 on one side. The end edges 111 and 121 of the first piece 11 and the second piece 12 are respectively provided with two adjacent fixing holes 14 along the length of their end edges 111 and 121 near the notch 13. Multiple hollow holes 15 are provided on the anti-crack component 1.
[0040] Multiple fixing rods 2 are respectively inserted and fixed in two corresponding fixing holes 14 of the first piece 11 and the second piece 12 of the multiple crack prevention components 1. The first piece 11 is defined with two imaginary longitudinal edge lines 161 passing through its two fixing rods 2, and the second piece 12 is defined with two imaginary transverse edge lines 162 passing through its two fixing rods 2. The two longitudinal edge lines 161 and the two transverse edge lines 162 together with the end edge 111 of the first piece 11 and the end edge 121 of the second piece 12 form a working area 16, and at least one positioning hole 17 is provided in the working area 16.
[0041] At least one positioning rod 3 is inserted into the corresponding positioning holes 17 of the plurality of anti-crack components 1. The positioning rod 3 is an iron nail, with a sharp end 31 and a stop end 32 formed at opposite ends, and the rod wall of the positioning rod 3 abuts against the hole wall of the positioning hole 17; please refer to the following: Figure 2 As shown:
[0042] The first piece 11 and the second piece 12 of the crack-prevention component 1 together form the L-shaped notch 13, which are respectively defined as the first side 112 and the second side 122. A resistance plate 4 is also provided, located at the notch 13 of the crack-prevention component 1. The resistance plate 4 includes a longitudinally arranged first piece 41 and a transversely arranged second piece 42, which are vertically connected as a single unit. The side of the first piece 41 of the resistance plate 4 is connected to the first side 112 of the adjacent first piece 11 of the crack-prevention component 1, and the side of the second piece 42 of the resistance plate 4 is connected to the second side 122 of the adjacent second piece 12 of the crack-prevention component 1. The resistance plate 4 has multiple through holes 43. Please refer to the attached document for further details. Figure 3 As shown, the resistance piece 4 can be folded into the front or rear side of the notch 13 of the anti-crack component 1 as needed, thereby forming an L-shaped resistance piece 4 that corresponds to the shape of the L-shaped notch 13.
[0043] Accordingly, in practice, the resistance piece 4 provided at the notch 13 of the plurality of anti-crack components 1 of the present invention is first folded concave to the front or rear side of the notch 13 of the anti-crack component 1. Please refer to the following: Figure 4 As shown, the present invention is then placed at the corner of a door frame 51 or a window frame 52, with the corner of the door frame 51 or window frame 52 abutting against the notch 13 and the resistance plate 4 of the anti-crack component 1 of the present invention. Please refer to the following: Figure 5 , Figure 6As shown, one end of the fixing rod 2 is then placed against the template 6 and the sharp end 31 of the positioning rod 3 is inserted into the template 6. The construction workers use hammers or other hammering tools to strike the stop end 32 of the positioning rod 3 so that the sharp end 31 of the positioning rod 3 is nailed into and fixed in the template 6. After multiple of the present inventions are nailed to the template 6 and fixed to the corners of the door frame 51 and window frame 52, multiple steel bars 7 are then arranged longitudinally and transversely around the door frame 51 and window frame 52. During construction, the longitudinal steel bars 71 and transverse steel bars 72 can be directly inserted from the outer sides 113 and 123 of the first piece 11 and the second piece 12 of the crack-prevention component 1 into the steel bar abutment area 21 formed between the outer sides 113 and 123 of the first piece 11 and the second piece 12 and the adjacent fixing rod 2, and the longitudinal steel bars 71 and transverse steel bars 72 abut against the fixing rod 2 adjacent to the outer sides 113 and 123 of the first piece 11 and the second piece 12, so as to improve the convenience of steel bar arrangement. The longitudinal steel bars 71 and transverse steel bars 72 are also tied and fixed with wire at the intersection.
[0044] Then, pre-mixed concrete is injected into the space formed by the multiple templates 6. At this time, the liquid concrete can flow smoothly between the multiple anti-crack components 1 and the resistance plates 4 through the hollow holes 15 on the multiple anti-crack components 1 and the through holes 43 on the resistance plates 4. This allows the concrete to cover each anti-crack component 1 and the resistance plates 4. After the concrete solidifies to form a wall structure, the present invention is tightly wrapped in the wall structure. The resistance plates 4 on the side of the notch 13 of the anti-crack component 1 can further increase the gripping area and the stability of the connection between the present invention and the wall structure, thereby improving the crack resistance strength at the front end of the wall structure at the corners of the door frame 51 and the window frame 52. Therefore, when the reinforced concrete (RC) wall is subjected to external forces such as earthquake shaking or thermal expansion and contraction, stress is generated at the corners of the door frame 51 and window frame 52. When the stress is transmitted to the notch 13 of the crack-resistant component 1, it will be blocked by the L-shaped resistance piece 4 set at the notch 13, thereby changing the direction of stress transmission and generating resistance to the external force. This reduces and disperses the effect of the external force on the stress end, thereby improving the stress resistance and crack resistance of the wall structure at the corners of the door frame 51 and window frame 52 at the front end of the stress, and thus effectively preventing the surface of the wall structure at the corners of the door frame 51 and window frame 52 at the front end of the stress from cracking or micro-cracking when subjected to earthquakes or other factors.
[0045] It is also worth mentioning that the present invention integrates the resistance plate 4 with the crack prevention component 1. When it is to be installed and used, the resistance plate 4 is folded concave to the front or rear side of the crack prevention component 1. This integrated design of the resistance plate 4 and the crack prevention component 1 not only significantly reduces the manufacturing cost of the present invention but also improves the convenience of installation and use. In addition, when not in use, since the resistance plate 4 is integrally connected to the notch 13 of the crack prevention component 1 and forms a flat plate with the crack prevention component 1, the space occupied by the resistance plate 4 in front of or behind the notch 13 of the crack prevention component 1 is avoided, thus saving the storage and transportation costs of the present invention.
[0046] The foregoing embodiments or drawings are not intended to limit the implementation of the present invention. The notch 13 and the resistance plate 4 of the anti-crack component 1 of the present invention can be L-shaped or arc-shaped. The resistance plate 4 of the present invention can be integrally connected to the notch 13 of the anti-crack component 1, and then folded concave to the front or rear side of the notch 13 of the anti-crack component 1 during installation and use. Alternatively, the L-shaped resistance plate 4 can be pre-spot-welded to the front or rear side of the notch 13 of the anti-crack component 1. In addition, the present invention may also provide two L-shaped resistance plates 4, which can be spot-welded to the front and rear sides of the notch 13 of the anti-crack component 1, respectively. Accordingly, any resistance plate 4 corresponding to the shape of the notch 13 of the anti-crack component 1 connected to at least one side of the notch 13 of the anti-crack component 1 should be considered as not departing from the protection scope of the present invention.
[0047] As can be seen from the above structure and implementation methods, the present invention has the following advantages:
[0048] 1. The anti-crack component structure of the corner wall of the door and window of the present invention has a resistance piece connected to at least one side of the notch of the anti-crack component, thereby increasing the gripping area and the stability of the connection with the wall structure at the corner of the door frame and window frame, thereby improving the crack resistance strength of the wall structure at the corner of the door frame and window frame at the front end of the force.
[0049] 2. The anti-crack component structure for door and window corner walls of the present invention has an L-shaped resistance plate connected to at least one side of the notch of the anti-crack component. When stress is transmitted to the resistance plate due to earthquakes or other events, it can be blocked by the resistance plate to change the direction of stress transmission and generate resistance to the external force. This reduces and disperses the effect of the external force on the stress end, thereby improving the stress resistance and crack resistance performance of the wall structure at the corner of the door and window frame, and thus preventing cracks or micro-cracks from occurring on the surface of the wall structure at the corner of the door and window frame.
[0050] 3. The anti-crack component structure of the corner wall of the door and window of the present invention has a resistance piece connected to at least one side of the notch of the anti-crack component. With this simple structural design, it can not only effectively improve the stress resistance and crack resistance of the wall structure at the corner of the door and window frame at the front end of the force, but also greatly save manufacturing costs and increase the convenience of assembly and use.
[0051] 4. The anti-crack component structure of the door and window corner wall of the present invention has a resistance piece integrally formed at the notch of the anti-crack component, and the resistance piece forms a flat plate. In this way, the space occupied by the resistance piece at the front and rear sides of the notch of the anti-crack component can be avoided when it is not in use, so as to save storage and transportation costs.
