Description

Technical Field

[0001] The present invention relates to the technical field of building members, and more specifically, provides a structure of a door and window corner wall crack prevention kit.

Background Art

[0002] All windows are attached to the walls of conventional buildings. When a building undergoes thermal expansion, cooling contraction, or vibration due to the shaking of an earthquake, cracks are likely to occur at the corner of the window frame on the wall, and rainwater may penetrate into the room through the cracks. Therefore, the inventor has conducted research and development to increase the crack resistance strength of the wall structures at the door and window corners and prevent situations where cracks and microcracks occur in the wall when subjected to an earthquake or other external forces. In conventional patent documents, for example, Patent Document 1 below discloses a "window corner structure wall crack prevention member", Patent Document 2 discloses a "window corner wall surface crack prevention kit fixing structure", Patent Document 3 discloses a "door and window corner wall surface crack prevention kit structure", Patent Document 4 discloses a "door and window corner wall surface crack prevention kit structure (VI)", and Patent Document 5 discloses a "door and window corner wall surface crack prevention kit structure (VII)", etc., which are door and window corner wall surface crack prevention kit structures.

[0003] Furthermore, after installing the above-mentioned door window corner wall crack prevention kit structure, the doors and windows that will be retained in the wall structure are molded, and after attaching the door and window frames to the doors and windows, the gaps that occur between them are filled with cement mortar to form a caulking seal. When seismic stress is transmitted to the caulking seal, microcracks are likely to occur in the caulking seal and its surface plaster layer. Therefore, the present inventor has conducted research and development, and for example, Patent Document 6 discloses a "door window corner wall crack prevention kit structure (vIII)" (see Figure 15). The door window corner wall crack prevention kit structure (m) mainly consists of a plurality of crack prevention members (m1) installed at intervals, which are fixed by a fixing rod (m2) passing through them, two reinforcing members (m31) of a reinforcement unit (m3) are connected to both ends of the fixing rod (m2), and an impact absorbing member (m32) is installed between the two reinforcing members (m31). Each of the two reinforcing members (m31) has a caulking-filled reinforcing section (m33) molded into it. When the door window corner wall crack prevention kit structure is installed and used, the caulking-filled reinforcing section (m33) is connected to the caulking at the corners of the door and window frames. The installation of the caulking-filled reinforcing section (m33) of the reinforcing unit (m3) improves the tear resistance strength of the wall structure and caulking at the corners of the door and window frames, and has the effect of protecting against the occurrence of microcracks in the caulking and plaster layer at the corners of the door and window frames during an earthquake.

[0005] However, as can be seen from the inventor's research history mentioned above, the inventor has used the product in practice and found room for further improvement, dedicating himself to making the product even easier to use and more practical. The "Door and Window Corner Wall Crack Prevention Kit Structure (8)" described in Patent Document 6, which the inventor had previously researched and developed, achieves the effect of increasing the tear resistance strength to the wall structure and caulking filling at the corners of doors and window frames by installing a reinforcing unit (m3). However, when assembling the impact absorbing member (m32), it is necessary to spot weld each of the notches of the multiple crack prevention members (m1) to fix them, making assembly and use still inconvenient and not ideal. Therefore, the inventor believed that the above shortcomings could be improved, and after diligent consideration, arrived at the proposal of the present invention, which effectively improves the above problems with a rational design.

[0006] This invention was made through diligent research by the inventors in view of the above-mentioned problems, and its purpose is to provide an improved door and window corner wall crack prevention kit structure that is easy to assemble and effectively prevents cracks from occurring in wall structures at the corners of doors and window frames. [Means for solving the problem]

[0007] To achieve the above objective, an improvement to the door window corner wall crack prevention kit structure in one embodiment of the present invention is achieved in which multiple crack prevention members, which are mainly installed at intervals, are fixed by passing a fixing rod through them, two reinforcing members of a reinforcement unit are installed at both ends of the fixing rod, and a seismic-resistant member between the two reinforcing members is installed across the notched portions of the multiple crack prevention members. Engagement grooves are formed on the two sides of the crack prevention members where the notches are formed, and these grooves are coupled to engage with hooks provided on the edges on both sides of the seismic-resistant member. In this way, the effect of easily assembling the seismic-resistant member and the crack prevention member is achieved. Furthermore, by installing the reinforcement unit, the gripping area with the wall structure at the corner of the door and window frame is increased, improving stress resistance performance and tear resistance strength, and effectively preventing the occurrence of microcracks and the like in the wall structure and its surface plaster layer at the corner of the door and window frame.

[0015] The reinforcement unit (4) comprises two opposing reinforcing members (41) and a seismic-resistant member (42) positioned between the two reinforcing members (41). The reinforcing members (41) and the seismic-resistant member (42) are stainless steel sheets, and the two reinforcing members (41) are positioned at both ends of the plurality of second fixing rods (22). The reinforcing members (41) are provided with a plurality of through holes (411) which are driven through to be positioned corresponding to both ends of the plurality of second fixing rods (22) and are spot-welded to the side of the seismic-resistant member (42). Each of the two reinforcing members (41) has a caulking-filled reinforcing portion (413) formed thereon, and the caulking-filled reinforcing portions (413) of the two reinforcing members (41) protrude from the first notch (13) of the crack prevention member (1) and are located outside the range defined by the work area (16). A right-angled notch (414) is formed in the caulking-filled reinforcement portion (413), and the seismic-resistant member (42) is positioned laterally across the first notches (13) of the multiple crack-preventing members (1), and is bent to form an L-shape corresponding to the first notches (13) of the multiple crack-preventing members (1). Multiple first holes (412) and multiple second holes (421) are provided in the two reinforcing members (41) and the seismic-resistant member (42), respectively.Referring together to Figures 4 and 5, the present invention is defined as having a first side (112) and a second side (122) respectively on one side of the L-shaped first notch (13) jointly formed by the first sheet portion (11) and the second sheet portion (12) of the crack prevention member (1), with a first engagement groove (113) provided on the first side (112) of the first sheet portion (11), and a second engagement groove (123) provided on the second side (122) of the second sheet portion (12), and the L-shaped seismic-resistant member (42) of the reinforcement unit (4) is located at one end edge adjacent to the first side (112) of the first sheet portion (11) of the crack prevention member (1) A first hook (422) is formed and coupled to engage with the first engagement groove (113) of the first sheet portion (11), and the L-shaped seismic-resistant member (42) has a second hook (423) formed at one end edge adjacent to the second side edge (122) of the second sheet portion (12) of the crack prevention member (1) and is coupled to engage with the second engagement groove (123) of the second sheet portion (12), and the surface of the L-shaped seismic-resistant member (42) has a raised ridge (424) formed between at least two adjacent second holes (421), and the surface of the L-shaped seismic-resistant member (42) is characterized by having an uneven shape formed on the surface of the L-shaped seismic-resistant member (42).

[0016] Referring to Figure 6, in implementation, the present invention is installed at the frame corner position of the template first door frame (51) or template first window frame (52), the frame corners of the template first door (51) and window frame (52) are brought into contact with the seismic-resistant member (42) of the reinforcement unit (4) of the present invention, one end of the first fixing rod (21) and the second fixing rod (22) are abutted against the template (53), and the tip (31) of the positioning rod (3) is inserted into the template (53). Subsequently, the installer strikes the stop end (32) of the positioning rod (3) with a hammer tool such as a mallet, driving in the tip (31) of the positioning rod (3) to fix it to the template (53). Multiple components of the present invention are attached to the template (53) and fixed to the frame corners of the first door (51) and the window frame (52). Then, referring to Figures 7 and 8 together, multiple reinforcing bars (6) are installed vertically and horizontally around the first door (51) and the window frame (52). During construction, the longitudinal reinforcement bars (61) and transverse reinforcement bars (62) are directly inserted from the outer edges (114) and (124) of the first sheet portion (11) and second sheet portion (12) of the crack prevention member (1) into the reinforcement contact area (23) formed between the outer edges (114) and (124) of the first sheet portion (11) and second sheet portion (12) and the adjacent fixing rod (2), so that the longitudinal reinforcement bars (61) and transverse reinforcement bars (62) come into contact with the fixing rod (2) adjacent to the outer edges (114) and (124) of the first sheet portion (11) and second sheet portion (12). To improve the convenience of arranging the reinforcement bars (6), the points where the longitudinal reinforcement bars (61) and transverse reinforcement bars (62) intersect are fixed by tying them with wire.

[0017] Then, ready-mix concrete is poured into the space formed by enclosing it with these templates (53). At this time, the liquid concrete passes through the gaps between the multiple crack prevention members (1) and the reinforcing members (41) of the reinforcement unit (4) and adjacent crack prevention members (1), the hollow holes (15) provided in the crack prevention members (1), and the first holes (412) and second holes (421) provided in the reinforcing members (41) and seismic-resistant members (42). In this way, after the concrete has hardened and the wall structure (9) has been formed (see Figure 10), the present invention is tightly covered inside the wall structure (9), and the multiple holes provided in the reinforcing material (41) and seismic-resistant member (42) of the reinforcing unit (4), as well as the multiple protrusions (424) provided on the surface of the seismic-resistant member (42), create an uneven surface on the surface of the reinforcing material (41) and seismic-resistant member (42), further increasing the gripping area between the present invention and the wall structure (9), making the bond stronger and increasing the tear resistance strength of the wall structure (9) at the corners of the first door (51) and window frame (52).

[0018] Furthermore, after forming the wall structure (9), the template first door (51) and the window frame (52) are removed, and a formal second door frame (71) or second window frame (72) for attachment to the door and window is formed on the wall structure (9), referring to Figures 9 and 10 together. After assembling the formal second door (71) and the window frame (72), a gap is formed between the second door (71) and the window frame (72) and the door and window of the wall structure (9). The caulking-filled reinforcing parts (413) provided on the two reinforcing members (41) of the reinforcement unit (4) of the present invention are located in the gap, and their notches (414) correspond to the frame corner positions of the second door (71) and the window frame (72). Then, the gap is filled using cement mortar to form a caulking fill (8). The caulking-filled reinforcing parts (413) of the reinforcement unit (4) of the present invention are covered with the caulking fill (8).

[0019] As a result, when a reinforced concrete (RC) wall is subjected to external forces such as seismic vibrations, thermal expansion, and cooling condensation, stress is generated at the corners of the wall surface of the second door (71) and window frame (72). When this stress is transmitted to the seismic-resistant member (42) installed at the first notch (13) of the crack prevention member (1) of the present invention, the L-shaped seismic-resistant member (42) is elastically deformable, buffering and absorbing the conduction of stress, altering the direction of stress conduction, and generating the effect of mitigating and dispersing the stress transmitted to the corners of the second door (71) and window frame (72). Therefore, the stress resistance and tear resistance performance of the wall structure (9) at the corners of the second door (71) and window frame (72) are improved, effectively preventing the occurrence of cracks and microcracks in the wall structure (9) and its surface plaster layer at the corners of the second door (71) and window frame (72). Furthermore, the stress transmitted to the caulking filling (8) is reinforced by the caulking filling reinforcement portion (413) of the reinforcing unit (4), thereby increasing the tear resistance strength of the caulking filling (8), absorbing the stress acting on the caulking filling (8), and effectively preventing the occurrence of cracks and microcracks in the caulking filling (8) and its surface plaster layer.

[0020] Figure 11 is an oblique view showing an improved door window corner wall crack prevention kit structure according to another embodiment of the present invention. In this invention, the installation of the caulking-filled reinforcement portion (413) of the two reinforcing members (41) of the reinforcement unit (4) is omitted as needed, and a second notch (415) is formed at the location of the caulking-filled reinforcement portion (413) of each, and the shape and position of the second notch (415) of the two reinforcing members (41) correspond to the L-shaped first notch (13) of the crack prevention member (1). Figure 12 is an exploded view showing an improved door window corner wall crack prevention kit structure according to yet another embodiment of the present invention. The two reinforcing members (41) of the reinforcement unit (4) have sheet-like first connecting portion (416) and second connecting portion (417) connected to the vertical and horizontal sides of the L-shaped second notch (415), respectively. During assembly, the first connecting portion (416) and the second connecting portion (417) of the two reinforcing members (41) are bent toward the seismic-resistant member (42), and are positioned adjacent to the seismic-resistant member (42) and overlapping it. The first connecting portion (416) and the second connecting portion (417) of the reinforcing members (41) are joined to the seismic-resistant member (42) at the overlapping portions by spot welding. In this way, the rigidity of the connection between the reinforcing members (41) and the seismic-resistant member (42) is further enhanced. Figures 13 and 14 show another embodiment of the present invention, in which a caulking-filled reinforcing portion (413) is formed in the second notch (415) of the two reinforcing members (41) of the reinforcement unit (4), and a first connecting portion (416) and a second connecting portion (417) are connected to the portions located next to the caulking-filled reinforcing portion (413) on the vertical and horizontal sides of the second notch (415) of the two reinforcing members (41), respectively. When assembling, the first connecting portion (416) and the second connecting portion (417) of the two reinforcing members (41) are bent toward the seismic-resistant member (42), and are installed adjacent to the seismic-resistant member (42) and overlapping with the seismic-resistant member (42), and the portions where the first connecting portion (416) and the second connecting portion (417) of the reinforcing members (41) and the seismic-resistant member (42) overlap each other are joined by spot welding.In this way, by providing the first connecting portion (416) and the second connecting portion (417), the contact area between the seismic-resistant member (42) and the reinforcing member (41) is increased, thereby improving the rigidity and convenience when joining the seismic-resistant member (42) and the reinforcing member (41) by spot welding.

[0021] From the above-described structure and implementation method, it can be seen that the present invention has the following advantages. 1. The improvement to the door window corner wall crack prevention kit structure according to the present invention is that engagement grooves are provided on the two sides of the first sheet portion and the second sheet portion of the crack prevention member in which the first notches are formed, and hooks are formed on the edges on both sides of the seismic-resistant member of the reinforcement unit, and these are coupled to engage with the engagement grooves provided on the sides of the first sheet portion and the second sheet portion of the crack prevention member, thereby improving the convenience of assembling the reinforcement unit and the crack prevention member. 2. The improved door window corner wall crack prevention kit structure according to the present invention is characterized by the horizontal installation of a seismic-resistant member at the first notch of the crack prevention member. When stress is transmitted to the seismic-resistant member, the seismic-resistant member is elastically deformable, so the stress is buffered and absorbed, and the direction of stress transmission is altered. In this way, the stress resistance and tear resistance performance of the wall structure at the corners of doors and window frames are enhanced, and the effect of preventing microcracks from occurring in the wall structure and its surface plaster layer at the corners of doors and window frames is achieved. 3. The improved door window corner wall crack prevention kit structure according to the present invention is characterized in that at least one connecting portion is connected to one side of the reinforcing material of the reinforcement unit where the second notch is provided, and the connecting portion overlaps with the seismic-resistant member. In this way, the contact area between the seismic-resistant member and the reinforcing material is increased, and the reinforcing material and the seismic-resistant member are joined by spot welding, further improving the robustness and convenience of the joint between the reinforcing material and the seismic-resistant member.

[0022] The present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the embodiments described above are merely illustrative in all respects and should not be constrained. The scope of the invention is defined by the claims and is not restricted by the text of the specification.
