ANTI-CRACKING ASSEMBLY STRUCTURE FOR DOOR AND WINDOW CORNER WALL AND ANTI-CRACKING COMPONENT THEREOF

Abstract

The present invention relates to an anti-cracking assembly structure for door and window corner wall and anti-cracking component thereof. The anti-cracking components of the anti-cracking assembly structure for door and window corner wall has a plurality of protruding ribs and grooves formed at intervals on a surface thereof. The protruding ribs and grooves are arc-shaped and arranged in parallel to each other. When the reinforced concrete wall is subjected to an external force and stress is generated at the corner of the door and window frames, the stress can be guided along the arc-shaped protruding ribs and arc-shaped grooves on the surface of anti-cracking component to change the transmission direction of the force at the stress end, so as to transmit and disperse the stress to the peripheral side more quickly. Accordingly, it can more effectively prevent the occurrence of 45-degree shear cracks at the corners.

[0021] To implement the present invention, referring to FIGS. 3, the present invention may be utilized on an outer side of a frame corner of a door frame (41) or a window frame (42), and the notch (13) of each of the anti-cracking components (1) of the present invention is corresponding to the frame corner position of the door frame (41) or window frame (42), wherein an end of each of the fixing rods (2) is pressed against the formwork, and the sharp ends (31) of the positioning rods (3) are respectively inserted into the formwork, and then the stop ends (32) of the positioning rods (3) are beaten by the subsequent construction personnel with a hammer or other percussion tool, so that the sharp ends (31) of the positioning rods (3) are nailed and fixed in the formwork. Since the present invention has the rod walls of the positioning rods (3) abut against the hole walls of the positioning holes (17), the positioning rods (3) passing through the positioning holes (17) can be maintained, and will not fall off due to vibration force generated when other positioning rods (3) are knocked and fixed, which improves the convenience of the present invention in installation.

[0022] Thus, referring to FIG. 4, when several assembly structures of the present invention are respectively nailed on the formwork and fixed at the corners of the door and window frames (41) and (42), several steel bars (5) are arranged longitudinally and laterally around the door and window frames (41) and (42). During the construction, the longitudinal steel bars (51) and the lateral steel bars (52) may be directly inserted into a steel bar resting area (21) formed between the adjacent fixing rods (2) through outer edges (112) and (122) of the first piece portion (11) and the second piece portion (12) of the anti-cracking components (1) respectively, and the longitudinal steel bars (51) and the lateral steel bars (52) abut against the fixing rods (2) respectively, so as to enhance the convenience in arranging the steel bars (5), and avoid the trouble for construction personnel in climbing the ladder frame and passing through the steel bars (5) from top to bottom. Then, iron wires are utilized at the intersections of the longitudinal steel bars (51) and the lateral steel bars (52) to bound and fix the arrangement of the steel bars (5).

[0023] Afterwards, the ready-mixed concrete is injected into the space defined by the formworks. At this moment, the liquid concrete can flow among the anti-cracking components (1) through the through holes (191) of the anti-cracking components (1), and be conducted through the arc-shaped protruding ribs (18) and arc-shaped grooves (19) on the surface of the anti-cracking components (1), which enhance the smoothness of the flow of the concrete on the surface of the anti-cracking components (1), and reduces the contact dead angle with the anti-cracking components (1), so that the concrete can completely cover the surface of the anti-cracking components (1). When the concrete covers the surface of the anti-cracking components (1), the concrete will be filled and attached to the reinforcement dimples (181) arranged on the surface of the anti-cracking components (1). Thereby, after the concrete is solidified to form the wall structure, the wall structure will relatively form a plurality of convex columns correspondingly embedded in the reinforcement dimples (181) of the anti-cracking components (1), so as to greatly increase the gripping area and the bonding stability of the anti-cracking components (1) of the present invention and the wall structure, so that it is unlikely for the wall structure to have relative displacement or separation from the anti-cracking components (1).

[0024] When the reinforced concrete (RC) wall is subjected to an external forces, such as earthquake shaking or thermal expansion and contraction, and stress is generated on the corner walls of the door and window frames (41) and (42), the strength and crack resistance of the wall structure can be enhanced by the stable combination of the wall structure at the corners of the door and the window frames (41) and (42) and the anti-cracking components (1), wherein the anti-cracking components (1) firmly combined with the wall structure absorbs the stress acting on the wall structure. Referring to FIGS. 5, the stress will be conducted through and along the plurality of arc-shaped protruding ribs (18) and arc-shaped grooves (19) on the surface of the anti-cracking components (1), so as to change the transmission direction of the force at the stress end, and disperse it more rapidly to the periphery of the anti-cracking components (1), so that the stress can be shared to and absorbed by the anti-cracking components (1). Accordingly, it not only prevents the anti-cracking components (1) from being twisted and deformed, but also prevents the wall structures of the door and window frames (41) and (42) from having 45-degree shear cracks at the corners. In addition, it is also facilitate to prevent cracks, micro-cracks, and etc. in the wall structure and surface paint layer at the corners of the doors and window frames (41) and (42).

[0025] It can be seen according to the above-mentioned structure and embodiments, advantages and effects provided by the present invention may include the following: [0026] 1. The anti-cracking assembly structure for door and window corner wall according to the present invention comprises a plurality of protruding ribs and grooves that are arc-shaped and spacingly arranged in parallel on the surface of each of the anti-cracking components. In this way, when the reinforced concrete wall is subjected to an external force and encounters stress generated at the corners of the door and window frames, the stress can be transmitted along the arc-shaped protruding ribs and grooves of each of the anti-cracking components, which change the transmission direction of the force at the stress end, and transmit the force to the peripheral side more quickly, so as to effectively prevent the occurrence of 45-degree shear cracks at the corners of the wall structure of the door and window frames. [0027] 2. The anti-cracking assembly structure for door and window corner wall according to the present invention comprises a plurality of protruding ribs and grooves that are arc-shaped and spacingly arranged in parallel on the surface of each of the anti-cracking components. In this way, when a stress generated at the corner of the door and window frames acts on the anti-cracking components, the conduction design of the arc-shaped protruding ribs and grooves of the anti-cracking components can quickly disperse the stress generated at the corner of the door and window frames to the periphery thereof so as to avoid the distortion and deformation of the anti-cracking components. It can also prevent cracks or micro-cracks in the wall structure at the corner of the door and window frames and surface paint layer thereof. [0028] 3. The anti-cracking assembly structure for door and window corner wall according to the present invention comprises a plurality of protruding ribs and grooves that are arc-shaped and spacingly arranged in parallel on the surface of each of the anti-cracking components. In this way, the conduction of the arc-shaped protruding ribs and grooves can facilitate the concrete to flow smoothly on the surface of the anti-cracking components and reduce its contact dead angle with the anti-cracking components, so as to increase the gripping area and binding tightness of the anti-cracking components and the wall structure, which further improves the structural strength and anti-cracking performance of the reinforced concrete wall.
