The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
In a first aspect, as shown in fig. 1 and 2, an embodiment of the present invention provides a deformation joint structure, including a first deformation joint 31 formed between adjacent first and second building structures 1 and 2, a first waterproof structure 4 provided between the first and second building structures 1 and 2 along the first deformation joint 31, the first waterproof structure 4 being for preventing water from penetrating into the first deformation joint 31; a drainage structure 6 is arranged below the first waterproof structure 4, and the drainage structure 6 is used for draining seepage water in the first deformation joint 31 when the first waterproof structure 4 fails so as to prevent the seepage water seeping into the first deformation joint 31 after accumulating.
Based on this, the deformation joint structure provided by the embodiment of the invention comprises a first deformation joint 31 formed between the adjacent first building structure 1 and the second building structure 2, a first waterproof structure 4 is arranged between the first building structure 1 and the second building structure 2 along the first deformation joint 31, and the first waterproof structure 4 is used for preventing water from penetrating into the first deformation joint 31; a drainage structure 6 is arranged below the first waterproof structure 4, and the drainage structure 6 is used for draining seepage water in the first deformation joint 31 when the first waterproof structure 4 fails so as to prevent the seepage water seeping into the first deformation joint 31 after accumulating. Therefore, the deformation joint structure provided by the embodiment of the invention comprises two waterproof lines, wherein the first waterproof structure 4 is arranged on the first waterproof line, and the second waterproof structure 6 is arranged on the second waterproof line, so that even if the first waterproof line fails, namely the first waterproof structure 4 leaks water, the second waterproof line drainage structure 6 can timely drain the water seepage in the first deformation joint 31, the combination of prevention and drainage is realized, and the condition that no water is accumulated in the first deformation joint 31 is ensured. Therefore, the deformation joint structure provided by the embodiment of the invention has the advantage that the safety and the effectiveness of water resistance are improved compared with the prior art which mainly takes water resistance and does not consider water drainage.
It is explained that due to the influence of temperature variation, uneven settlement, earthquake and other factors, additional stress is generated inside the building structure, and the stress often cracks or even breaks the building. In order to reduce the influence of stress on the building, the structure is broken at the deformation sensitive part in advance during design, and the gap, namely the deformation joint, is reserved so as to ensure that each broken part of the building has enough deformation space without damaging or cracking the building. Therefore, the first deformation joint 31 needs to satisfy the requirements of extension, earthquake resistance and settlement of the building. That is, the width of the first deformation joint 31 should satisfy the width regulation of the deformation joint by the building structure design-related specification, and should be equal to or greater than the sum of the deformation of the first building structure 1 and the deformation of the second building structure 2 caused by the structural temperature difference shrinkage, that is, the sum of the deformation of the first building structure 1 and the deformation of the second building structure 2
ΔL＝ΔL1+ΔL2；
Wherein, Δ L1Is the horizontal deflection, Δ L, of the first building structure 12Is the amount of horizontal deformation of the second building structure 2;
ΔL1＝αL1ΔT；
ΔL2＝αL2ΔT；
wherein, alpha is the coefficient of thermal contraction deformation, L1Horizontal length, L, of first building structure 12The second building structure 2 has a horizontal length Δ T which is a temperature variation value.
In particular, for Δ L1And Δ L2The structural modeling is carried out, the calculation and analysis are carried out through three-dimensional finite element software, and then the width of the first deformation joint 31 is calculated according to delta L1And Δ L2And (4) setting.
If the first building structure 1 and the second building structure 2 are reinforced concrete structures, the drainage structure 6 can be provided as a reinforced concrete structure integrated with the first building structure 1, i.e. the drainage structure 6 belongs to a part of the main structure of the first building structure 1. Because the reinforced concrete structure is not ageing easily like waterproof construction such as rubber, so set up drainage structures 6 to the reinforced concrete structure who links as an organic whole with second building structure 2 can increase waterproof construction's life, can have the same life with first building structure 1 and second building structure 2, satisfy building life year requirement. Therefore, the deformation joint structure provided by the embodiment of the invention has a more reliable waterproof effect compared with the existing deformation joint structure.
Alternatively, as shown in fig. 1, 2 and 3, in the deformation joint structure according to the embodiment of the present invention, the drainage structure 6 includes a drainage channel 61 opened upward, and a first sidewall 611 of the drainage channel 61 is formed on the bottom surface of the first building structure 1; a second deformation joint 32 is formed between the second side wall 612 of the drainage channel 61 and the bottom surface of the second building structure 2; two ends of the drainage channel 61 in the extending direction are provided with a head plate 614, and a third deformation joint is formed between the head plate 614 and the bottom surface of the second building structure 2; the bottom 613 of the drain tank is provided with a water guiding pipe 7.
Further, the water introduction duct 7 may be provided at both ends of the extending direction of the bottom 613 of the drain tank. Like this, the both ends of drain tank 61 are discharged fast to the ponding in the infiltration drain tank 61, reduce ponding dwell time in drain tank 61, avoid the rainwater to gather and appear the seepage, increase water-proof effects. The drainage structure 6 is provided with the drainage groove 61 with the structure, so that the structure is simple and the construction is easy.
Alternatively, the water introduction pipe 7 may extend to an outdoor rainwater pipe so that water in the drain tank 61 may be discharged to the outdoor rainwater pipe through the water introduction pipe 7.
In the deformation joint structure provided by the embodiment of the invention, as shown in fig. 1, fig. 2 and fig. 4, the first waterproof structure 4 may specifically be a deformation joint device equipped with a water stop. Preferably, the water stop is a steel plate water stop, the first waterproof structure includes a first steel plate water stop 41 and a second steel plate water stop 42 as shown in fig. 2 and 4, specifically, the first steel plate water stop 41 is fixed between the edge of the top surface of the first building structure 1 and the edge of the top surface of the second building structure 2 to prevent water from penetrating into the first deformation joint 31 from above the first deformation joint 31; a second steel water stop 42 is secured between the end closure panel 614 and the edge of the side of the second building structure 2 to prevent water from seeping between the end closure panel 614 and the second building structure 2 into the first deformation joint 31; wherein, first steel sheet waterstop 41 and second steel sheet waterstop 42 sealing connection, optionally, first steel sheet waterstop 41 and second steel sheet waterstop 42 welding. Of course, the waterstop may be made of other materials, such as rubber waterstop, but the rubber waterstop is degraded in performance such as cohesiveness and elongation under long-term reciprocating deformation and temperature difference of the building structure, is prone to cracking and separation, is insufficient in durability, and causes water-stopping function failure, and the steel plate waterstop is good in deformability and can meet the requirements of settlement, shock resistance and extension of the building, so that the waterstop adopting the steel plate waterstop is adopted as the deformation joint structure optimization scheme provided by the embodiment of the invention.
Optionally, the first steel plate water stop 41 is provided with a first mounting hole (not shown in fig. 2), the edges of the first building structure 1 and the second building structure 2 are provided with a second mounting hole (not shown in fig. 2), and the first steel plate water stop 41 and the first building structure 1 and the second building structure 2 can be fixed by inserting the bolt 43 into the first mounting hole and the second mounting hole. Specifically, the bolt 43 may be an internal expansion type metal expansion bolt 43. Adopt interior expanding metal expansion bolts 43 to fix, can ensure the firm in connection between steel sheet waterstop and first building structure 1 and the second building structure 2, avoid appearing the not hard up phenomenon of bolt 43. The fixing manner of the second steel plate water stop 42 is similar to that of the first steel plate water stop 41, and is not described herein again.
Optionally, circular arc, recess type or V style of calligraphy can be chooseed for use to the shape of above-mentioned steel sheet waterstop, and wherein, the V style of calligraphy is preferred scheme, because the steel sheet waterstop is the form of contained angle, when first building structure 1 and second building structure 2 receive flexible pulling force, it can absorb the stress variation that flexible brought through the change of contained angle size, avoids the steel sheet waterstop to receive the stress influence and the fracture appears, and then avoids first waterproof construction 4 to appear leaking the phenomenon.
In addition, the thickness of the drainage channel 61 may be set according to the fire rating of the first building structure 1 and the fire rating of the second building structure 2, so that the drainage channel 61 may also serve as a fire retardant belt for the deformation joint. For example, the thickness of the drainage channel 61 can be determined according to the "fire protection code for building design", and the specific implementation process includes: firstly, looking up 'building design fire protection code' to determine the fire resistance grade of a building; secondly, the fire-resistant time limit of the plate of the drainage channel 61 is determined according to the fire-resistant grade; thirdly, the thickness of the drainage channel 61 is determined according to the fifth rule in the attached table in the appendix of "fire codes for architectural design" corresponding to the above-mentioned fire-retardant time limit.
Further, as shown in fig. 2, a second waterproof structure 5 is provided along the second deformation joint 32 between the bottom surface of the second building structure 2 and the second side wall 612 of the drain groove 61, and the second waterproof structure 5 is used to prevent water penetrating into the drain groove 61 from overflowing from the second deformation joint 32. The second waterproof structure 5 can effectively prevent accumulated water from overflowing from the second deformation joint 32 in the drainage groove 61 when the water guide pipe 7 is blocked and drainage is not smooth, so that a third waterproof defense line of the deformation joint is formed, and the third waterproof defense line is matched with the first waterproof defense line and the second waterproof defense line to prevent water, so that the combination of 'preventing, draining and preventing' three defense lines is formed, and the deformation joint structure provided by the embodiment of the invention can prevent and drain water more thoroughly.
In particular, in order to make the width of the deformation joint between the first 1 and second 2 building structures conform to the standard, the width of the second deformation joint 32 is set equal to the width of the first deformation joint 31.
Specifically, like the first waterproof structure 4, the second waterproof structure 5 may be a steel water stop that is not prone to aging, specifically, a third steel water stop 51 shown in fig. 2 and 3, such as a stainless steel water stop.
In a second aspect, as shown in fig. 5, an embodiment of the present invention further provides a method for constructing a deformation joint structure, which is used for constructing the deformation joint structure according to the first aspect, and specifically includes:
step S1, constructing the first building structure 3, the second building structure 2, and the drainage structure 6 under the position where the first waterproof structure 4 is scheduled to be installed, leaving a gap between the first building structure 1 and the second building structure 2 to form the first deformation joint 31;
step S2, installing the first waterproof structure 4 between the first building structure 1 and the second building structure 2 along the first deformation joint 31.
According to the construction method of the deformation joint structure provided by the embodiment of the invention, as the deformation joint structure built by the method comprises the first deformation joint 31 formed between the adjacent first building structure 1 and the second building structure 2, the first waterproof structure 4 is arranged between the first building structure 1 and the second building structure 2 along the first deformation joint 31; the first waterproof structure 4 is for preventing water from penetrating into the first deformation joint 31; a drainage structure 6 is arranged below the first waterproof structure 4, and the drainage structure 6 is used for draining seepage water in the first deformation joint 31 when the first waterproof structure 4 fails. Therefore, the deformation joint structure built by the method comprises two waterproof lines, the first waterproof structure 4 is arranged on the first waterproof line, and the second waterproof structure 6 is arranged on the second waterproof line, so that even if the first waterproof line fails, namely the first waterproof structure 4 leaks water, the second waterproof line drainage structure 6 can timely drain the water seepage in the first deformation joint 31, the waterproof and drainage combination is achieved, and the condition that no water is accumulated in the first deformation joint 31 is ensured. Therefore, compared with the prior art, the construction method of the deformation joint structure provided by the embodiment of the invention can improve the safety and the effectiveness of water resistance.
Specifically, as shown in fig. 1, 2 and 3, the drainage structure 6 includes a drainage channel 61 opening upward, and a first side wall 611 of the drainage channel 61 is formed at the bottom surface of the first building structure 1; a second deformation joint 32 is formed between the second side wall 612 of the drainage channel 61 and the bottom surface of the second building structure 2; the drain tank 61 is provided with end caps 614 at both ends in the extending direction thereof, and the drain tank 61 is provided with a water guide pipe 7 at the bottom thereof.
Based on this, when the first building structure 1 is constructed in step S1, the first side wall 611 of the drainage channel 61 and the bottom 613 of the drainage channel are constructed on the bottom surface of the first building structure 1;

step S13, installing a water guide pipe at the bottom of the drainage groove;
s14, constructing end sealing plates at two ends of the drainage tank;
and step S15, constructing a second building structure.
It is understood that after the construction of step S11 is completed, the section of formwork is removed after the strength of the first building structure 11, the first side wall 611 of the drainage channel 61 and the bottom 613 of the drainage channel is satisfied; step S12 is performed again. In addition, in order to facilitate the removal of the inner form of the second sidewall 612 in step S12, the inner form thereof is a light foam form that is easy to remove.
It should be noted that the second building structure 2 can be constructed simultaneously with the first building structure 1, before the first building structure 1 is constructed or after the first building structure 1 is constructed, which is determined by the actual situation.
Further, as shown in fig. 2, 3 and 4, a second waterproof structure 5 is provided between the bottom surface of the second building structure 2 and the second side wall 612 of the drain groove 61 along the second deformation joint 32, and the second waterproof structure 5 is used to prevent water penetrating into the drain groove 61 from overflowing from the second deformation joint 32.
Based on this, when the second building structure 2 is constructed in step S15, the upper end of the second waterproof structure 5 is embedded in the second building structure 2;
wherein, step S12 specifically includes:
step S121, constructing a first portion 6121 of the second sidewall 612 at an end of the bottom 613 of the drainage channel away from the first sidewall 611, where the first portion 6121 is a portion of the second sidewall 612 from the bottom 613 of the drainage channel to a lower end of the second waterproof structure 5 and a portion of the second sidewall 612 between the second waterproof structure 5 and the first sidewall 611;
