[0023] The inside-outside directions described in the whole text are Figure 1 In the direction indicated by the middle arrow, the length direction of the concrete body 10 is a horizontal direction, that is, perpendicular to the thickness direction of the concrete body 10 .
[0024] See also Figure 1 and Figure 2 Now, the full-through external wall induced seam structure of the super-long basement provided by the utility model is described. The full-through external wall induced seam structure of the super-long basement includes a concrete body 10, a water stop 20, and two groups of reinforcing components 30. Both sides of the concrete body 10 are provided with inwardly concave induced seams 11, and the induced seams 11 extend in the up-down direction; the water stop 20 is arranged in the concrete body 10 and extends in the up-down direction. The water stop 20 is arranged opposite to the induced seam 11. The water stop 20 has a protrusion 21 that protrudes in an arc shape to one side and extends in the up-down direction. One side of the water stop 20 is provided with a positioning pin 22 that extends in the thickness direction of the concrete body 10; the two groups of reinforcing components 30 are arranged in the concrete body 10 and are symmetrically arranged on both sides of the water stop 20, and one group of reinforcing components 30 is connected to the positioning pin 22.
[0025] The embodiment of the present application provides a full-through exterior wall induced seam structure for an extra-long basement. During its actual use, the position of the reinforcement component 30 is first fixed, and the positioning pin 22 is tied to the reinforcement component 30 to fix the position of the waterstop 20 (for waterproofing). Then, the templates at various locations are installed in place and concrete is poured to form a concrete body 10. After the concrete body 10 solidifies, the outer induced seam 11 is filled with caulking paste. When the concrete body 10 is deformed, the induced seam 11 induces the concrete body 10 to crack only at the induced seam 11 to avoid irregular distribution of cracks. When the concrete body 10 is deformed, the protrusion 21 is stretched toward a horizontal state, and the positioning pin 22 is tied and fixed to the reinforcement component 30, thereby limiting the movement of the waterstop 20 when the concrete body 10 is deformed to ensure the waterproof quality of the concrete body 10.
[0026] Compared with the prior art, the full-through exterior wall induced joint structure of the extra-long basement provided in this embodiment has the following advantages. When the concrete body 10 is deformed, the induced joint 11 induces the concrete body 10 to crack only from the induced joint 11, thereby avoiding irregular distribution of cracks. When the concrete body 10 is deformed, the protrusion 21 is stretched toward a horizontal state, and the positioning pin 22 is tied and fixed with the reinforcement component 30, thereby limiting the movement of the water stop strip 20 when the concrete body 10 is deformed, so as to ensure the waterproof quality of the concrete body 10.
[0027] In a possible implementation, the reinforcing component 30 is as follows: Figure 1 The structure shown, see Figure 1The reinforcement component 30 includes two groups of first vertical bars 31, two groups of first transverse bars 32 and fixing parts 33. The two groups of first vertical bars 31 are symmetrically arranged on both sides of the induced joint 11. Each group of first vertical bars 31 includes a plurality of first vertical bars 31 spaced apart along the length direction of the concrete body 10, and the first vertical bars 31 extend in the up-down direction; the two groups of first transverse bars 32 are symmetrically arranged on both sides of the induced joint 11 and are connected to the two groups of first vertical bars 31 in a one-to-one correspondence. The first transverse bars 32 are located on the side of the first vertical bars 31 close to the water stop 20. Each group of first transverse bars 32 includes a plurality of first transverse bars 32 spaced apart along the up-down direction, and the first transverse bars 32 extend in the length direction of the concrete body 10; the fixing parts 33 are arranged between the first transverse bars 32 and the water stop 20.
[0028] Specifically, two groups of reinforcement components 30 are respectively arranged close to the inner wall and the outer wall of the concrete body 10, the first vertical reinforcement 31 is fixedly connected to the ground, and each first transverse reinforcement 32 of each group is tied and fixed to each first vertical reinforcement 31 of the corresponding group to strengthen the strength of the concrete body 10, and the fixing piece 33 is tied and fixed to the positioning pin 22, which not only facilitates the position fixation of the water stop belt 20, but also further strengthens the strength of the concrete body 10.
[0029] In some embodiments, see Figure 1 The fixing member 33 includes two groups of second vertical ribs 332 and a plurality of second transverse ribs 331. The two groups of second vertical ribs 332 are symmetrically arranged on both sides of the induced joint 11. Each group of second vertical ribs 332 includes a plurality of second vertical ribs 332 spaced apart along the length direction of the concrete body 10, and the second vertical ribs 332 extend along the up-down direction; a plurality of second transverse ribs 331 are spaced apart along the up-down direction and are located on the side of the second vertical ribs 332 close to the water stop 20, and the second transverse ribs 331 extend along the length direction of the concrete body 10, and the positioning pins 22 are connected to the second transverse ribs 331.
[0030] Specifically, each second transverse reinforcement 331 is tied and fixed to each second vertical reinforcement 332 in each group of second vertical reinforcements 332 , and the positioning pin 22 is tied and fixed to the second transverse reinforcement 331 , which not only facilitates the position fixation of the water stop strip 20 , but also further enhances the strength of the concrete body 10 .
[0031] Furthermore, two groups of positioning pins 22 are arranged at intervals along the length direction of the concrete body 10 , each group of positioning pins 22 includes a plurality of positioning pins 22 arranged at intervals along the up-down direction, and each positioning pin 22 is tied and fixed to each second transverse reinforcement 331 in a one-to-one correspondence.
[0032] In some embodiments, see Figure 1 The first transverse rib 32 has a bent portion 321 at one end close to the induction seam 11 , which is bent toward the side close to the second vertical rib 332 , and the bent portion 321 is connected to the second vertical rib 332 .
[0033] Specifically, the bending portion 321 is tied and fixed to the second vertical reinforcement 332, and the bending portion 321 is arranged close to the induced joint 11 to strengthen the strength on both sides of the induced joint 11, so that the concrete body 10 only cracks from the induced joint 11 when deformed, avoiding irregular distribution of cracks in the concrete body 10.
[0034] In a possible implementation, the water stop strip 20 is Figure 1 The structure shown, see Figure 1 Both side edges of the water stop strip 20 are provided with a deformation portion 23 bent toward a side away from the positioning pin 22 .
[0035] Specifically, the angle between the deformation portion 23 and the water stop strip 20 is an obtuse angle. When the concrete body 10 is deformed, the deformation portion 23 also deforms toward a horizontal state to adapt to the deformation of the concrete body 10. On the premise of the raised portion 21, the water stop strip 20 is further prevented from jumping when the concrete body 10 is deformed.
[0036] In a possible implementation, the concrete body 10 is formed as follows: Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 Two strip seats 40 are symmetrically arranged on both sides of the induced joint 11 on the inner side wall of the concrete body 10, and the strip seats 40 extend in the up and down directions. A sealing strip 50 for sealing the induced joint 11 is provided on the side of the strip seat 40 away from the concrete body 10, and the sealing strip 50 is connected to one of the strip seats 40.
[0037] Specifically, the slat seat 40 is connected to the concrete body 10 by self-tapping screws, and the blocking slat 50 is used to cover the induced joint 11 located on the inner side of the concrete body 10 to increase the aesthetics of the inner side of the concrete body 10. The blocking slat 50 is connected to one of the slat seats 40 by self-tapping screws. The width of the blocking slat 50 is much larger than the width of the induced joint 11. When the concrete body 10 is deformed, that is, when the induced joint 11 cracks, since the blocking slat 50 is only connected to one of the slat seats 40, the blocking slat 50 can adapt to the deformation of the concrete body 10 without damage and continue to cover the induced joint 11, thereby improving practicality.
[0038] In some embodiments, see Figure 1 and Figure 2 The two side edges of the two slat seats 40 that are separated from each other respectively have transition portions 41 that are bent toward the side away from the concrete body 10, and the edges of the two transition portions 41 that are away from the concrete body 10 have mounting portions 42 that are bent toward each other. The sealing slat 50 is located between the mounting portion 42 and the slat seat 40, and is connected to one of the mounting portions 42.
[0039] Specifically, an accommodating gap for accommodating the blocking strip 50 is formed between the mounting portion 42 and the strip seat 40, which not only facilitates the installation of the blocking strip 50 in the accommodating gap, but also facilitates the connection of the blocking strip 50 with one of the mounting portions 42 by self-tapping screws.
[0040] In some embodiments, see Figure 1 and Figure 2 A decorative layer 60 is coated on the inner wall of the concrete body 10 , and the decorative layer 60 is located on a side of the strip board seat 40 away from the induced joint 11 .
[0041] Specifically, a side surface of the decoration layer 60 away from the concrete body 10 is flush with a side surface of the mounting portion 42 away from the strip seat 40 , further improving the aesthetics of the inner wall surface.
[0042] In a possible implementation, the concrete body 10 is formed as follows: Figure 1 The structure shown, see Figure 1 A waterproof layer 70 is provided on the outer wall of the concrete body 10 .
[0043] Specifically, the waterproof layer 70 covers the outer wall of the concrete body 10 , and the waterproof layer 70 shields the induced joint 11 located outside the concrete body 10 , thereby improving the waterproof effect of the entire concrete body 10 .
[0044] In some embodiments, see Figure 1 An outer protective layer 80 is provided on the outer side wall of the waterproof layer 70 .
[0045] Specifically, the outer protective layer 80 completely covers the waterproof layer 70 and is used to protect the waterproof layer 70 to further ensure the waterproof effect of the concrete body 10 .
[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
