Description

Technical Field

[0001] The invention relates to the field of building structure and construction, and in particular to a deformation joint structure and a construction method thereof. Background Art

[0002] In civil buildings, in order to reduce the temperature difference shrinkage effect of super-long structures and to ensure the rationality and regularity of structural layout, expansion joints are often required to meet the expansion, seismic and settlement requirements of buildings. Expansion joints often cause water leakage in the basement top plate and roof of buildings. Therefore, the expansion joint structure and its construction method have always been the focus and difficulty of civil building waterproofing.

[0003] In the prior art, the purpose of waterproofing the building structure is usually achieved by installing a rubber waterstop in the middle of the expansion joint, filling a water-swelling waterstop strip inside the expansion joint, embedding polyvinyl chloride putty on the surface of the expansion joint, or installing an expansion joint device manufactured by a professional manufacturer and equipped with a waterstop and a fire barrier strip at the expansion joint.

[0004] However, the existing expansion joints are generally only provided with one waterproof line, and the waterproof safety reserve is insufficient. When the waterproof line fails, leakage problems will occur. For example, the rubber water stop strip provided in the middle of the expansion joint will age due to long-term use, which will cause water leakage from the roof or basement top plate. Moreover, when the waterproof line fails, the water that penetrates into the expansion joint is not easy to be discharged due to the shielding of the waterproof line. Summary of the invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0047] First, as Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a deformation joint structure, including a first deformation joint 31 formed between adjacent first building structures 1 and second building structures 2, a first waterproof structure 4 is provided along the first deformation joint 31 between the first building structure 1 and the second building structure 2, the first waterproof structure 4 is used to prevent water from penetrating into the first deformation joint 31; a drainage structure 6 is provided below the first waterproof structure 4, the drainage structure 6 is used to discharge the seepage water in the first deformation joint 31 when the first waterproof structure 4 fails, so as to prevent the water that has penetrated into the first deformation joint 31 from accumulating and then seeping out.

[0048] Based on this, the deformation joint structure provided by the embodiment of the present invention includes a first deformation joint 31 formed between the adjacent first building structure 1 and the second building structure 2, and a first waterproof structure 4 is provided along the first deformation joint 31 between the first building structure 1 and the second building structure 2, and the first waterproof structure 4 is used to prevent water from penetrating into the first deformation joint 31; a drainage structure 6 is provided below the first waterproof structure 4, and the drainage structure 6 is used to discharge the seepage water in the first deformation joint 31 when the first waterproof structure 4 fails, so as to prevent the water that has penetrated into the first deformation joint 31 from accumulating and then seeping out. Therefore, the deformation joint structure provided by the embodiment of the present invention includes two waterproof lines, the first line is the first waterproof structure 4, and the second line is the drainage structure 6, so that even if the first waterproof line fails, that is, the first waterproof structure 4 leaks, the second waterproof line drainage structure 6 can also discharge the seepage water in the first deformation joint 31 in time, so as to achieve the combination of waterproofing and drainage, and ensure that there is no water accumulation in the first deformation joint 31. Therefore, the deformation joint structure provided by the embodiment of the present invention increases the safety and effectiveness of waterproofing compared with the prior art that focuses on "waterproofing" and does not consider "drainage".

[0049] It needs to be explained that due to the influence of factors such as temperature changes, uneven settlement and earthquakes, additional stress will be generated inside the building structure. This stress often causes cracks in the building or even damages it. In order to reduce the impact of stress on the building, the structure is disconnected in the deformation-sensitive parts in advance during the design, and gaps, i.e., deformation joints, are reserved to ensure that the disconnected parts of the building have enough deformation space without damaging the building or causing cracks. Therefore, the above-mentioned first deformation joint 31 must meet the expansion, seismic and settlement requirements of the building. In other words, in addition to meeting the width requirements of the deformation joint in the relevant specifications for building structure design, the width of the first deformation joint 31 should also be greater than or equal to the sum of the deformation of the first building structure 1 and the deformation of the second building structure 2 caused by the temperature difference contraction of the structure, i.e.

[0050] ΔL=ΔL1+ΔL2;

[0051] Wherein, ΔL1 is the horizontal deformation of the first building structure 1, and ΔL2 is the horizontal deformation of the second building structure 2;

[0052] ΔL1=αL1ΔT;

[0053] ΔL2=αL2ΔT;

[0054] Among them, α is the temperature difference shrinkage deformation coefficient, L1 is the horizontal length of the first building structure 1, L2 is the horizontal length of the second building structure 2, and ΔT is the temperature change value.

[0055] Specifically, structural modeling should be performed for ΔL1 and ΔL2, and the values ​​are calculated and analyzed using three-dimensional finite element software, and then the width of the first deformation joint 31 is set according to ΔL1 and ΔL2.

[0056] If the first building structure 1 and the second building structure 2 are reinforced concrete structures, the drainage structure 6 can be set as a reinforced concrete structure connected to the first building structure 1, that is, the drainage structure 6 is part of the main structure of the first building structure 1. Since the reinforced concrete structure is not as easy to age as the waterproof structure such as rubber, the drainage structure 6 is set as a reinforced concrete structure connected to the second building structure 2 to increase the service life of the waterproof structure, and can have the same service life as the first building structure 1 and the second building structure 2, meeting the service life requirements of the building. In this way, the deformation joint structure provided by the embodiment of the present invention has a more reliable waterproof effect than the existing deformation joint structure.

[0057] Optional, such as Figure 1 , Figure 2 and Figure 3 As shown, in the deformation joint structure provided in the embodiment of the present invention, the drainage structure 6 includes a drainage groove 61 opening upward, and the first side wall 611 of the drainage groove 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 groove 61 and the bottom surface of the second building structure 2; head plates 614 are provided at both ends of the extension direction of the drainage groove 61, and a third deformation joint is formed between the head plates 614 and the bottom surface of the second building structure 2; a water pipe 7 is provided at the bottom 613 of the drainage groove.

[0058] Furthermore, the water guide pipe 7 can be arranged at both ends of the extension direction of the bottom 613 of the drainage groove. In this way, the accumulated water infiltrating into the drainage groove 61 can be quickly discharged from both ends of the drainage groove 61, reducing the residence time of the accumulated water in the drainage groove 61, avoiding the accumulation of rainwater and leakage, and increasing the waterproof effect. The drainage structure 6 is arranged as the drainage groove 61 of the above structure, which is simple in structure and easy to construct.

[0059] Optionally, the water pipe 7 can be extended to an outdoor rainwater pipe, so that the water in the drainage trough 61 can flow through the water pipe 7 to the outdoor rainwater pipe for discharge.

[0060] In the deformation joint structure provided in the embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the first waterproof structure 4 can be specifically selected from a deformation joint device equipped with a water stop strip. Preferably, the water stop strip is a steel plate water stop strip. The first waterproof structure includes: Figure 2 and Figure 4 The first steel plate waterstop 41 and the second steel plate waterstop 42 shown, specifically, the first steel plate waterstop 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; the second steel plate waterstop 42 is fixed between the edge of the head plate 614 and the side of the second building structure 2 to prevent water from penetrating into the first deformation joint 31 from between the head plate 614 and the second building structure 2; wherein the first steel plate waterstop 41 and the second steel plate waterstop 42 are sealed and connected, and optionally, the first steel plate waterstop 41 and the second steel plate waterstop 42 are welded. Of course, the waterstop can also be made of other materials, such as rubber waterstop. However, due to the long-term reciprocating deformation of the building structure and the temperature difference, the adhesion, elongation and other properties of the rubber waterstop will be degraded, and it is easy to crack and detach, and its durability is insufficient, resulting in the failure of the waterstop function. The steel plate waterstop has good deformability and can meet the settlement, shockproof and expansion requirements of the building. Therefore, the preferred solution of the deformation joint structure provided in the embodiment of the present invention is to use a steel plate waterstop as the waterstop.

[0061] Optionally, the first steel plate water stop strip 41 is provided with a first mounting hole ( Figure 2 The first building structure 1 and the second building structure 2 have second mounting holes (not shown). Figure 2 (not shown in the figure), by inserting the bolt 43 into the first mounting hole and the second mounting hole, the first steel plate waterstop 41 can be fixed to the first building structure 1 and the second building structure 2. Specifically, the bolt 43 can be an internal expansion type metal expansion bolt 43. The use of the internal expansion type metal expansion bolt 43 for fixing can ensure that the steel plate waterstop is firmly connected to the first building structure 1 and the second building structure 2, and avoid the phenomenon of the bolt 43 loosening. The fixing method of the second steel plate waterstop 42 is similar to the fixing method of the first steel plate waterstop 41 mentioned above, and will not be repeated here.

[0062] Optionally, the shape of the steel plate waterstop can be arc-shaped, groove-shaped or V-shaped, among which the V-shape is the preferred option, because the steel plate waterstop is in the form of an angle. When the first building structure 1 and the second building structure 2 are subjected to expansion and contraction tension, it can absorb the stress changes caused by the expansion and contraction by changing the size of the angle, thereby avoiding cracking of the steel plate waterstop due to the influence of stress, and further avoiding water leakage in the first waterproof structure 4.

[0063] In addition, the plate thickness of the drainage trough 61 can be set according to the fire resistance level of the first building structure 1 and the fire resistance level of the second building structure 2, so that the drainage trough 61 can also serve as a fire barrier of the expansion joint. For example, the plate thickness of the drainage trough 61 can be determined according to the "Code for Fire Protection Design of Buildings", and the specific implementation process includes: first, consulting the "Code for Fire Protection Design of Buildings" to determine the fire resistance level of the building; second, determining the fire resistance time limit of the plate of the drainage trough 61 according to the above fire resistance level; third, determining the plate thickness of the drainage trough 61 according to the fifth provision in the appendix of the "Code for Fire Protection Design of Buildings" corresponding to the above fire resistance time limit.

[0064] Further, such as Figure 2 As shown, between the bottom surface of the second building structure 2 and the second side wall 612 of the drainage groove 61, a second waterproof structure 5 is provided along the second deformation joint 32, and the second waterproof structure 5 is used to prevent water that has infiltrated into the drainage groove 61 from overflowing from the second deformation joint 32. The second waterproof structure 5 can effectively prevent the accumulated water from overflowing from the second deformation joint 32 in the drainage groove 61 when the water pipe 7 is blocked and the drainage is not smooth, and constitutes the third waterproof defense line of the deformation joint, which cooperates with the first waterproof defense line and the second waterproof defense line to form a combination of the three defense lines of "prevention, drainage, and prevention", so that the deformation joint structure provided by the embodiment of the present invention is more thoroughly waterproof and drainable.

[0065] Specifically, in order to make the width of the deformation joint between the first building structure 1 and the second building structure 2 meet the standard, the width of the second deformation joint 32 is set to be equal to the width of the first deformation joint 31 .

[0066] Specifically, the second waterproof structure 5 can be made of a steel plate water stop that is not easy to age, just like the first waterproof structure 4. Figure 2 and Figure 3 The third steel plate waterstop 51 shown is, for example, a steel plate waterstop made of stainless steel.

[0067] Second, as Figure 5 As shown, an embodiment of the present invention further provides a construction method of a deformation joint structure, which is used for the construction of the deformation joint structure of the first aspect, and specifically includes:

[0068] Step S1, constructing a first building structure 3, a second building structure 2, and a drainage structure 6 below a location where a first waterproof structure 4 is to be installed, leaving a gap between the first building structure 1 and the second building structure 2 to form a first deformation joint 31;

[0069] Step S2 : installing the first waterproof structure 4 along the first deformation joint 31 between the first building structure 1 and the second building structure 2 .

[0070] The construction method of the deformation joint structure provided by the embodiment of the present invention comprises a first deformation joint 31 formed between the adjacent first building structure 1 and the second building structure 2, and a first waterproof structure 4 is provided along the first deformation joint 31 between the first building structure 1 and the second building structure 2; the first waterproof structure 4 is used to prevent water from penetrating into the first deformation joint 31; a drainage structure 6 is provided below the first waterproof structure 4, and the drainage structure 6 is used to discharge the seepage water in the first deformation joint 31 when the first waterproof structure 4 fails. Thus, the deformation joint structure constructed by the method comprises two waterproof lines, the first being the first waterproof structure 4 and the second being the drainage structure 6, so that even if the first waterproof line fails, that is, the first waterproof structure 4 leaks, the second waterproof line drainage structure 6 can timely discharge the seepage water in the first deformation joint 31, so as to achieve the combination of waterproofing and drainage, and ensure that there is no water accumulation in the first deformation joint 31. Therefore, the construction method of the deformation joint structure provided by the embodiment of the present invention can increase the safety and effectiveness of waterproofing compared with the prior art.

[0071] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the drainage structure 6 includes a drainage groove 61 opening upward, and a first side wall 611 of the drainage groove 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 groove 61 and the bottom surface of the second building structure 2; head plates 614 are provided at both ends of the extension direction of the drainage groove 61, and a water pipe 7 is provided at the bottom of the drainage groove 61.

[0072] Based on this, when constructing the first building structure 1 in step S1, the first side wall 611 and the bottom 613 of the drainage ditch 61 are constructed on the bottom surface of the first building structure 1;

[0073] At this time, step S1 specifically includes:

[0074] Step S11, constructing the first building structure 1, the first side wall 611 of the drainage trough 61 and the bottom 613 of the drainage trough;

[0075] Step S12, constructing a second side wall 612 at one end of the bottom 613 of the drainage groove away from the first side wall 611;

[0076] Step S13, installing a water pipe at the bottom of the drainage trough;

[0077] Step S14, constructing head plates at both ends of the drainage trough;

[0078] Step S15: construct a second building structure.

[0079] It is understood that after the construction of step S11 is completed, the part of the template is removed after the strength of the first building structure 11, the first side wall 611 of the drainage trough 61 and the bottom 613 of the drainage trough meets the requirements, and then step S12 is constructed. In addition, in order to facilitate the removal of the template on the inner side of the second side wall 612 in step S12, the template on the inner side adopts a lightweight foam template that is easy to remove.

[0080] It should be noted that the construction of the second building structure 2 can be carried out simultaneously with the construction of the first building structure 1, or can be constructed before the construction of the first building structure 1 or after the construction of the first building structure 1 is completed, depending on the actual situation.

[0081] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, 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 drainage groove 61 , and the second waterproof structure 5 is used to prevent water infiltrating into the drainage groove 61 from overflowing from the second deformation joint 32 .

[0082] Based on this, when constructing the second building structure 2 in step S15, the upper end of the second waterproof structure 5 is pre-buried on the second building structure 2;

[0083] Wherein, step S12 specifically includes:

[0084] Step S121, constructing a first portion 6121 of the second side wall 612 at one end of the bottom 613 of the drainage groove away from the first side wall 611, wherein the first portion 6121 is a portion of the second side wall 612 from the bottom 613 of the drainage groove to the lower end of the second waterproof structure 5 and a portion of the second side wall 612 located between the second waterproof structure 5 and the first side wall 611;

[0085] Step S122, installing the lower end of the second waterproof structure 5 on the first part 6121;

[0086] Step S123 , constructing the second part 6122 of the second side wall 612 on the upper end of the first part 6121 of the second side wall 612 , wherein the second part 6122 is a part of the second side wall 612 that is higher than the lower end of the second waterproof structure 5 and is located outside the second waterproof structure 5 and the first side wall 611 .

[0087] At this time, when the water pipe 7 is blocked and drainage is not smooth, the second waterproof structure 5 can effectively prevent the accumulated water from overflowing from the second deformation joint 32 in the drainage groove 61, forming a third waterproof line of the deformation joint, and cooperating with the first waterproof line and the second waterproof line to form a combination of the three lines of defense of "prevention, drainage, and prevention", so that the deformation joint structure provided by the embodiment of the present invention is more thorough in preventing drainage.

[0088] The construction method of the above-mentioned deformation joint structure also includes:

[0089] Step S3, sealingly connecting the first waterproof structure 4 and the second waterproof structure 5.

[0090] The first waterproof structure 4 and the second waterproof structure 5 may be sealed and connected by welding.

[0091] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0092] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
