Description

Technical Field

[0001] This utility model relates to the field of external wall crack induction technology, specifically a controllable induction structure device for basement external wall cracks. Background Technology

[0002] Cracks in basement exterior walls are structural gaps that appear in the walls, floor slabs, or roof slabs due to factors such as concrete shrinkage, temperature changes, uneven foundation settlement, and load effects. If these cracks develop unchecked, they may compromise the overall structural integrity, cause groundwater leakage, and even exacerbate steel reinforcement corrosion, affecting the durability and safety of the project. Therefore, induced structural measures are needed to prevent large-scale, irregular cracking.

[0003] Basement exterior walls are prone to structural cracks due to concrete shrinkage, temperature changes, foundation settlement, and load. If these cracks develop uncontrollably, they can damage the overall structure, cause groundwater leakage, exacerbate steel corrosion, seriously affect the durability and safety of the project, and increase maintenance costs and safety hazards. Therefore, we propose a controllable crack-inducing structural device for basement exterior walls. Utility Model Content

[0006] The basement exterior wall crack controllable induction structure includes an L-shaped wall-mounted frame and two side frames fixedly connected to the two outer walls of the wall-mounted frame. The wall-mounted frame is equipped with two first bolts at both the upper and lower ends, and the side frames are equipped with second bolts at both the upper and lower ends.

[0007] Crack induction mechanisms are provided at both the upper and lower ends of the wall-mounted frame and the side frame. The crack induction mechanism includes two induction rods, with a rotating ring fixedly connected between the induction rods. Both ends of the induction rods are threaded with a third bolt. A crack comparison groove is provided through the middle of the wall-mounted frame and the side frame. A rotating groove is provided at both the upper and lower ends of the crack comparison groove, and the rotating groove is distributed on the inner and outer walls of the wall-mounted frame and the side frame. A ring groove is provided through the rotating groove, and several threaded grooves that are threaded to the third bolt are provided through the ring groove.

[0008] As a preferred embodiment of this utility model, the overall spatial distribution of the crack induction mechanism on the wall-mounted frame is greater than that on the side frame.

[0010] As a preferred embodiment of this utility model, the inner diameter of the rotating groove matches the outer diameter of the guide rod, and the guide rod is slidably connected to the rotating groove, with the rotating ring positioned at the upper and lower ends of the crack comparison groove.

[0011] As a preferred embodiment of this utility model, a fine threaded rod is fixedly connected to one end of each of the third bolts, and the outer diameter of the fine threaded rod is smaller than the inner diameter of the annular groove.

[0012] Compared with existing technologies, the beneficial effects of this utility model of controllable crack induction structure device for basement exterior walls are as follows: by combining and fixing the L-shaped wall-mounted frame and the side frame, a stable constraint is formed on the wall, guiding the crack to occur in the preset area; the crack induction mechanism can precisely control the direction of the crack by adjusting the angle of the induction rod, the induction mechanism on the wall-mounted frame dominates the direction, and the side frame blocks the convergence of cracks.

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present invention should be understood according to the specific circumstances.

[0022] See Figure 1-4 As shown, the controllable induction structure device for cracks in the basement exterior wall according to the present invention includes an L-shaped wall-mounted frame 1 and two side frames 2 fixedly connected to the two outer walls of the wall-mounted frame 1. The wall-mounted frame 1 is provided with two first bolts 11 at both the upper and lower ends, and the side frames 2 are provided with second bolts 21 at both the upper and lower ends.

[0023] In use, the L-shaped wall-mounting frame 1 is attached to the exterior wall surface of the basement and fixed in place by the first bolts 11 at the top and bottom. Then, the two side frames 2 are aligned with the outer walls of the wall-mounting frame 1 on both sides and fixed using the second bolts 21 at the top and bottom of the side frames 2. The overall structure, through the combination of the wall-mounting frame 1 and the side frames 2, forms a constraint on a specific area of ​​the wall, initially guiding cracks caused by concrete shrinkage or stress to occur within a controllable range around the frame, preventing the disorderly spread of cracks.

[0024] In this embodiment of the utility model, crack induction mechanisms 3 are provided at both the upper and lower ends of the wall-mounted frame 1 and the side frame 2. The crack induction mechanism 3 includes two induction rods 31, and a rotating ring 32 is fixedly connected between the induction rods 31. A third bolt 33 is threaded through both ends of the induction rods 31. A crack comparison groove 301 is provided through the middle of the wall-mounted frame 1 and the side frame 2. A rotating groove 302 is provided at both the upper and lower ends of the crack comparison groove 301, and the rotating grooves 302 are distributed on the inner and outer walls of the wall-mounted frame 1 and the side frame 2. An annular groove 303 is provided through the rotating groove 302, and a crack is provided through the annular groove 303. There are several threaded grooves 304 that are threaded to the third bolt 33. The overall spatial distribution of the crack induction mechanism 3 on the wall frame 1 is larger than that on the side frame 2. The opening end of the rotating groove 302 is set in a straight face near the crack reference groove 301. The inner diameter of the rotating groove 302 matches the outer diameter of the induction rod 31, and the induction rod 31 is slidably connected to the rotating groove 302. The rotating ring 32 is set at the upper and lower ends inside the crack reference groove 301. One end of the third bolt 33 is fixedly connected to a fine threaded rod 34. The outer diameter of the fine threaded rod 34 is smaller than the inner diameter of the ring groove 303.

[0025] In use, after the wall-mounted bracket 1 and side bracket 2 are attached to the wall and fixed with bolts, the crack direction can be precisely controlled by the crack guiding mechanism 3. Specifically, the guiding rod 31 is inserted into the rotating groove 302, slid to a preset angle, and then connected and fixed to the corresponding threaded groove 304 by the third bolt 33 (which, together with the fine threaded rod 34, passes through the annular groove 303). The rotating ring 32 is positioned in the crack reference groove 301. The guiding mechanism on the wall-mounted bracket 1, due to its larger spatial distribution, can control the main cracking direction; the guiding mechanism on the side bracket 2, through angle adjustment, blocks the convergence path of adjacent cracks, preventing small cracks from merging into large cracks. Later, the crack development can be observed through the crack reference groove 301 to ensure it expands according to the preset direction and range, improving the structural safety of the wall.

[0026] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
