Description

[Technical Field]

[0001] This invention relates to the field of prefabricated building technology, and in particular to a building structure and joint method. [Background Technology]

[0002] Currently, in modular integrated concrete buildings, seams are created between the container units after they are hoisted. Modular concrete is widely used in the construction industry. If the building experiences rain or leaks in the floors, water can seep in through these seams.

[0003] Traditional methods for treating joints typically involve mixing polyethylene foam rods with cement mortar for primary sealing and waterproofing. However, because polyethylene foam rods are porous, they easily absorb moisture from the cement mortar over time. This moisture absorption causes deformation and weakens adhesion, leading to mortar leakage through the foam rods. Furthermore, during cement mortar pouring, the foam rods, lacking sufficient load-bearing capacity, can easily fall into the gaps, causing further seepage. This seepage significantly reduces the lifespan of the concrete modules. In short, existing jointing techniques for modular concrete structures have a limited lifespan due to their inherent waterproofing limitations. [Summary of the Invention]

[0004] To address the problems of short waterproof lifespan and poor waterproofing effect in existing building structures, this invention provides a building structure and joint method.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a building structure, the building structure comprising at least two building modules, a joint structure and a sealing structure; the two building modules are spaced apart to form a gap space, and the connection between the gap space and the outside is defined as an opening;

[0006] The joint structure includes at least two fasteners and a receiving member. The two fasteners are located within the joint space and are respectively connected to two building modules. Each fastener includes a main section, a snap-fit ​​section, and a connecting section. The snap-fit ​​section is provided at both ends of the main section. One side of the main section can contact the surface of the building module within the joint space, and the connecting section is provided on the other side. The end of the connecting section away from the connection with the main section is bent towards the side closer to the opening to form a connecting groove. The sealing structure is located within the joint space near the opening. The sealing structure includes a sealing layer and a mud layer. The sealing layer is located within the joint space, and one side of it is connected to the end of the snap-fit ​​section near the opening, while the other side is connected to the mud layer. The receiving member is sandwiched between the two fasteners and is detachably connected to the fasteners, forming a waterproof cavity with the fasteners to prevent external water from seeping into the joint space.

[0007] Preferably, the receiving component is a U-shaped groove, which defines the interior and the outer surface of the U-shaped groove. The interior of the U-shaped groove can be used to receive water, and the opposite ends of the outer surface of the U-shaped groove are provided with support arms.

[0008] Preferably, the connecting groove cooperates with the arm to implement a detachable connection between the fastener and the receiving member.

[0009] Preferably, a first damping element is provided in the connecting groove, and a second damping element is provided on the side of the support arm away from the U-shaped groove opening. When the connecting groove and the support arm are engaged, the first damping element and the second damping element are in contact.

[0010] Preferably, the sealing structure includes a sealing layer and a mud layer. The sealing layer is disposed within the gap space, with one side connected to the end of the snap-fit ​​section near the opening and the other side connected to the mud layer.

[0011] Preferably, a space is provided between the end of the sealing layer away from the mud layer and the receiving component.

[0012] Preferably, the joint structure further includes bolts, which are threaded through the main body section near the connecting section and connected to the building module.

[0013] To solve the above-mentioned technical problems, the present invention provides another technical solution as follows: a jointing method applied to the above-mentioned building structure, the jointing method comprising the following steps:

[0014] Offers multiple building modules and joint structures;

[0015] The joint structure is installed on the surface of the building module based on the preset installation position;

[0016] Multiple building modules are spliced ​​together with corresponding joint structures to form gap spaces;

[0017] The pre-installed location is designed to fill the gap with a sealing structure to prevent water from entering the gap.

[0018] Preferably, the joint structure includes at least two fasteners and a receiving element, and forming the gap space specifically includes the following steps:

[0019] The fasteners are installed onto the surfaces of multiple building modules based on preset installation positions;

[0020] Multiple building modules are spliced ​​together by connecting fasteners installed on the surfaces of different building modules with support members.

[0021] Compared with the prior art, the building structure and joint method provided by the present invention have the following beneficial effects:

[0022] 1. An embodiment of the present invention provides a building structure comprising at least two building modules, a joint structure, and a sealing structure; the two building modules are spaced apart to form a gap space, with the connection between the gap space and the outside being an opening; the joint structure includes at least two fasteners and a receiving member, the two fasteners being disposed within the gap space and respectively connected to the two building modules; the sealing structure is disposed within the gap space near the opening and connected to the end of the fasteners near the opening; the receiving member is sandwiched between the two fasteners and detachably connected to the fasteners, forming a waterproof cavity with the fasteners to prevent external water from seeping into the gap space. The sealing structure and waterproof cavity in the building structure provided in this embodiment can effectively block water from entering the gap space, thereby solving the problems of short waterproof life and poor waterproof effect in existing building structures.

[0023] 2. The fastener of this invention includes a main body segment, a snap-fit ​​segment, and a connecting segment. Snap-fit ​​segments are provided at both ends of the main body segment. One side of the main body segment can contact the surface of the building module within the gap space, and the other side is provided with a connecting segment. The end of the connecting segment away from the connection with the main body segment is bent towards the opening to form a connecting groove. The connection between the fastener and the building module can be completed simultaneously during the factory prefabrication of the building module. That is, the building module can be shipped together with the fastener, saving significant installation time and improving assembly efficiency during the assembly of the building modules into a building structure.

[0024] 3. In this embodiment of the invention, the receiving component is a U-shaped channel. The U-shaped channel defines the interior and the outer surface of the U-shaped channel. The interior of the U-shaped channel can be used to collect water, and the opposite ends of the outer surface of the U-shaped channel are provided with support arms. The opening of the U-shaped channel needs to be provided with a corresponding opening so that the waterproof cavity formed can collect water that seeps in through the opening.

[0025] 4. The connecting groove and the support arm of the present invention cooperate to realize the detachable connection of the fixing part and the receiving part, which is simple and convenient.

[0026] 5. In this embodiment of the invention, a first damping element is provided in the connecting groove, and a second damping element is provided on the side of the support arm away from the U-shaped groove opening. When the connecting groove and the support arm are engaged, the first damping element and the second damping element come into contact. The contact between the first damping element and the second damping element allows them to provide each other with a large damping force, increasing friction and making the connection between the fixing element and the receiving element tighter. Secondly, it can improve the airtightness of the waterproof cavity, thereby improving the waterproof effect.

[0027] 6. The sealing structure of this embodiment includes a sealing layer and a grout layer. The sealing layer is disposed within the joint space, with one side connected to the end of the snap-fit ​​section near the opening, and the other side connected to the grout layer. The sealing layer can be a polyethylene rod. The polyethylene rod is used to fill the space from the joint structure to the opening to prevent water, dust, pollutants, etc., from entering the concrete through the opening.

[0028] 7. In this embodiment of the invention, the end of the sealing layer away from the mud layer has an accommodating space between it and the receiving component, which increases the capacity of the waterproof cavity and thus helps to improve the waterproof performance of the building structure.

[0029] 8. The joint structure of this embodiment of the invention also includes bolts, which penetrate the main body section near the connecting section and connect to the building module, thereby enhancing the tightness of the connection between the fastener and the building module.

[0030] 9. This embodiment of the invention also provides a jointing method, which has the same beneficial effects as the above-described building structure, and will not be described in detail here. [Attached Image Description]

Detailed Implementation Methods

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0047] In the embodiments provided by this invention, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0048] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Those skilled in the art should also recognize that the embodiments described in the specification are optional embodiments, and the actions and modules involved are not necessarily essential to the invention.

[0049] In various embodiments of the present invention, it should be understood that the sequence number of each process does not necessarily imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0050] The flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of this application. In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions indicated in the blocks may occur in a different order than those indicated in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, or they may sometimes be executed in reverse order, depending on the functions involved. It is particularly important to note that each block in a block diagram and / or flowchart, and combinations of blocks in block diagrams and / or flowcharts, can be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.

[0051] Currently, in modular integrated concrete buildings, seams are formed between the concrete modules after the box-type structures are hoisted. While modular concrete is widely used in the construction industry, during rainy weather or when leaks occur, water can seep into the walls through these seams, potentially causing water seepage and significantly impacting the living experience of residents.

[0052] Traditional methods for treating joints typically involve mixing polyethylene foam rods with cement mortar for primary sealing and waterproofing. However, because polyethylene foam rods are porous, they easily absorb moisture from the cement mortar over time. This moisture absorption causes deformation and weakens adhesion, leading to mortar leakage. Furthermore, during cement mortar pouring, polyethylene foam rods, due to insufficient load-bearing capacity, can easily fall into the joints, creating gaps that allow for water seepage. This significantly reduces the lifespan of the concrete modules. In short, existing jointing techniques for modular concrete structures result in poor waterproofing and a limited lifespan for waterproofing.

[0053] To resolve the above issues, please refer to Figure 1 The first embodiment of the present invention provides a building structure 100, which includes at least two building modules 1, a joint structure 2 and a sealing structure 3; the two building modules 1 are spaced apart to form a gap space 11, and the connection between the gap space 11 and the outside is set as an opening 12;

[0054] The joint structure 2 includes at least two fasteners 21 and a receiving member 22. The two fasteners 21 are located in the gap space 11 and are respectively connected to the two building modules 1. The sealing structure 3 is located in the gap space 11 near the opening 12 and is connected to the end of the fastener 21 near the opening 12. The receiving member 22 is sandwiched between the two fasteners 21 and is detachably connected to the fasteners 21, and forms a waterproof cavity 24 with the fasteners 21 to prevent external water from seeping into the gap space 11.

[0055] Understandably, existing buildings are typically constructed by assembling multiple building modules 1, where building module 1 refers to a concrete block. For example, during the assembly of two building modules 1, they are usually spaced apart to form a gap space 11. This gap space 11 typically includes expansion joints, settlement joints, or construction joints. An expansion joint is a structural joint installed vertically at an appropriate location along the length of the building to prevent cracks or damage to the structure caused by changes in climate temperature (such as thermal expansion and contraction of building module 1). An expansion joint divides building components above the foundation, such as walls, floors, and roofs, into two independent parts, allowing the building to expand and contract horizontally along its length.

[0056] Settlement joints are vertical joints installed to prevent damage to buildings caused by uneven settlement of the foundation. When a building is constructed on foundations with varying soil types and properties, or when adjacent parts of the building differ significantly in height, load, and structural form, or when the foundation depth of adjacent walls varies considerably, continuous vertical joints should be installed at these points of difference to divide the building into several independent units that can settle freely. A significant difference between settlement joints and expansion joints is that settlement joints extend continuously from the building's foundation to the roof.

[0057] A construction joint is a joint formed between concrete poured in stages due to design requirements or construction needs. It is not a physical "seam," but rather a bonding surface between the later-poured concrete and the earlier-poured concrete, created when the latter has exceeded its initial setting time.

[0058] For further information, please refer to [link / reference]. Figure 1The building structure 100 formed by assembling building modules 1 can generally be divided into interior walls and exterior walls. The interior walls are prone to seepage when encountering indoor water leaks. Exterior walls, typically exposed to the elements, are highly susceptible to rain and are even more prone to seepage. Due to the presence of gaps, this embodiment uses a joint structure 2 and a sealing structure 3 within the gap space 11 to prevent water from entering. Specifically, the sealing structure 3 is positioned near the opening 12 within the gap space 11 to seal the opening 12, forming a waterproof measure. The sealing structure 3 seals the opening 12 of the gap space 11, preventing water from entering the gap space 11 through the opening 12. The waterproof cavity 24 formed by the receiving member 22 and the fixing member 21 serves as another waterproof measure. In one possible implementation, a small amount of water entering through the sealing structure 3 can be contained within the waterproof cavity 24, preventing further entry into the gap space 11. It should be understood that the sealing structure 3 and waterproof cavity 24 in the building structure 100 provided in this embodiment can effectively block water to prevent water from entering the gap space 11, thereby solving the problems of short waterproof life and poor waterproof effect of the building structure 100 in the prior art.

[0059] Furthermore, please combine Figure 1 and Figure 2 The receiving element 22 is specifically a U-shaped groove. Specifically, the U-shaped groove defines the interior 241 and the outer surface of the U-shaped groove. The interior 241 is part of the aforementioned waterproof cavity 24, and its function is to collect water to prevent water from entering the gap space 11. The opposite ends of the outer surface of the U-shaped groove are provided with support arms 25. Furthermore, the opening of the U-shaped groove needs to correspond to the opening 12 so that the formed waterproof cavity 24 can collect water that seeps in through the opening 12.

[0060] It should be noted that the receiving part 22 can also be a V-shaped groove or other groove-shaped component of any shape. Its function is to form a waterproof cavity 24 with the side of the fixing part 21 near the opening 12. Therefore, there is no restriction on the specific shape of the receiving part 22.

[0061] Furthermore, please combine Figure 1 and Figure 3The fastener 21 includes a main body section 211, a snap-fit ​​section 212, and a connecting section 213. The main body section 211 has snap-fit ​​sections 212 at both ends. One side of the main body section 211 can contact the surface of the building module 1 within the gap space 11, and the other side has a connecting section 213. It should be understood that since one side of the main body section 211 can directly contact the surface of the building module 1, during the assembly of the building module 1, the fastener 21 is usually fixed to the surface of the building module 1 first; specifically, the main body section 211 is connected to the surface of the building module 1. The snap-fit ​​section 212 can connect to the sealing structure 3 to support the sealing structure 3. It should be noted that the connection between the fastener 21 and the building module 1 can be completed simultaneously during the factory prefabrication of the building module 1. That is, the building module 1 can be shipped together with the fastener 21, which saves a significant amount of installation time and improves assembly efficiency during the assembly of the building module 1 into the building structure 100.

[0062] Please refer to the following: Figure 4 In one possible implementation, the end of the lap arm 25 away from the connection with the U-shaped groove can be bent away from the opening 12 to form an overlap groove 250. The end of the connecting segment 213 away from the connection with the main body segment 211 is bent towards the side closer to the opening 12 to form a connecting groove 214. In this embodiment, the connecting groove 214 is formed by bending the end of the connecting segment 213 away from the connection with the main body segment 211 towards the side closer to the opening 12. Therefore, the installation direction of the fastener 21 needs to be considered when installing the main body segment 211 on the surface of the building module 1.

[0063] Please refer to the following: Figure 5 In another possible implementation, the support arm 25 can be arranged perpendicular to the outer surface of the U-shaped groove, and the side of the support arm 25 away from the opening of the U-shaped groove forms an overlap groove 250 with the surface of the U-shaped groove. The connecting section 213 includes a first connecting section 2131 and a second connecting section 2132, which are spaced apart on the same side of the main body section 211. The end of the first connecting section 2131 away from the connection with the main body section 211 is bent toward the side closer to the second connecting section 2132, and the end of the second connecting section 2132 away from the connection with the main body section 211 is bent toward the side closer to the first connecting section 2131. The first connecting section 2131, the second connecting section 2132 and the main body section 211 together form a connecting groove 214, which is connected to the support arm 25 to implement a detachable connection between the fastener 21 and the receiving member 22. In this embodiment, the connecting groove 214 is formed by the first connecting segment 2131, the second connecting segment 2132, and the main body segment 211. Therefore, when installing the main body segment 211 on the surface of the building module 1, there is no need to consider the installation direction of the fastener 21. That is, the assembly efficiency can be accelerated when assembling the fastener 21.

[0064] Furthermore, the connecting groove 214 cooperates with the boom 25 to implement a detachable connection between the fastener 21 and the receiving member 22. It should be understood that the two fasteners 21 are respectively fixed to the surfaces of two different building modules 1. When assembling the two building modules 1, they are connected through the overlapping groove 250 and the connecting groove 214 on the boom 25, thus completing the assembly process of the building modules 1 and forming a waterproof cavity 24 for waterproofing. It should be noted that the connection process between the boom 25 and the connecting groove 214 is carried out simultaneously during the assembly of the building modules 1, that is, during the on-site construction phase of hoisting the building modules 1.

[0065] Furthermore, please combine Figure 4 and Figure 5 A first damping element 2141 is provided within the connecting groove 214, and a second damping element 251 is provided on the side of the support arm 25 away from the U-shaped groove opening. When the connecting groove 214 and the support arm 25 are engaged, the first damping element 2141 and the second damping element 251 come into contact. It should be understood that, in order to improve the waterproof effect of the waterproof cavity 24 formed by the fixing member 21 and the receiving member 22, the first damping element 2141 is provided within the connecting groove 214, and the second damping element 251 is provided on the side of the support arm 25 away from the U-shaped groove opening. Specifically, the first damping element 2141 and the second damping element 251 are made of hot-melt rubber. Firstly, the contact between the first damping element 2141 and the second damping element 251 allows them to provide a greater damping force to each other, increasing friction and making the connection between the fixing member 21 and the receiving member 22 tighter. Secondly, it improves the airtightness of the waterproof cavity 24, thereby enhancing the waterproof effect.

[0066] Please see Figure 1The sealing structure 3 includes a sealing layer 31 and a grout layer 32. The sealing layer 31 is disposed within the joint space 11, with one side connected to the end of the snap-fit ​​section 212 near the opening 12, and the other side connected to the grout layer 32. It should be understood that the sealing layer 31 is connected to the end of the snap-fit ​​section 212 near the opening 12, and the snap-fit ​​section 212 of the two fasteners 21 limits the sealing layer 31, preventing it from sliding down into the joint space 11 under the weight of the grout layer 32. Specifically, the sealing layer 31 can be a polyethylene rod. The polyethylene rod is used to fill the space from the joint structure 2 to the opening 12 to prevent water, dust, contaminants, etc., from entering the concrete through the opening 12. This helps maintain the integrity and durability of the concrete. In addition, the polyethylene rod has good sealing performance and can effectively prevent water leakage into the concrete structure through the joint. This helps maintain the durability and waterproofness of the building structure 100. Furthermore, the building structure 100 will be subject to deformation and stress caused by thermal expansion and contraction, loads, etc., during use. Polyethylene rods possess a certain degree of elasticity, which can alleviate concrete deformation and stress to some extent, reducing the impact on structural load. It should be understood that the waterproof cavity 24 is one layer of waterproofing, while the sealing layer 31 forms another layer of waterproofing to prevent water from entering the waterproof cavity 24 through the opening 12. This helps improve the overall waterproofing performance of the building structure 100.

[0067] It should be noted that the sealing layer 31 can be any one of the following materials: polyethylene rod, rubber rod, polyurethane rod, or expandable sealant tape, or a mixture of multiple materials.

[0068] Furthermore, the slurry layer 32 can fill the space from the sealing layer 31 to the opening 12, further enhancing the sealing performance of the building structure 100 and improving its waterproofing and seepage prevention effects. In addition, the cement component in the slurry can react with the surface of the building module 1 within the gap space 11 to form a strong adhesive interface, thereby increasing the bonding strength and durability of the slurry layer 32.

[0069] Furthermore, a receiving space 242 is provided between the end of the sealing layer 31 away from the mud layer 32 and the receiving member 22. It should be understood that the receiving space 242 is part of the waterproof cavity 24. The larger the receiving space 242, the larger the capacity of the waterproof cavity 24, and the more water it can hold. Therefore, ensuring that a receiving space 242 is provided between the end of the sealing layer 31 away from the mud layer 32 and the receiving member 22 increases the capacity of the waterproof cavity 24, thereby helping to improve the waterproof performance of the building structure 100.

[0070] Furthermore, please combine Figure 1 and Figure 3The joint structure 2 also includes bolts 26, which pass through the main body section 211 near the connecting section 213 and connect to the building module 1. It should be understood that, in order to enhance the tightness of the connection between the fastener 21 and the building module 1, it is preferable to implement a threaded connection by means of bolts 26 passing through the main body section 211 near the connecting section 213 and connecting to the building module 1.

[0071] Please continue reading. Figure 1 The slurry layer 32 fills the space between the sealing layer 31 and the opening 12 so that the side of the slurry layer 32 away from the sealing layer 31 is flush with the surface of the building module 1. Furthermore, a protective layer 4 is also provided on the side of the slurry layer 32 away from the sealing layer 31. The protective layer 4 includes a base layer 41 and a finishing layer 42 stacked together. The base layer 41 may be made of a waterproof coating to protect the surface of the building module 1. The finishing layer 42 may be made of a decorative coating to enhance the aesthetics of the building structure 100.

[0072] Figure 6a , Figure 6b and Figure 6c This is an example illustration of the position of the joint structure 2 provided by the present invention within the gap space 11. It should be understood that the gap space 11 can connect an inner wall and an outer wall. The inner wall and the outer wall may be separated by only one building module 1. Alternatively, they may be separated by multiple building modules 1. Taking the case where the inner wall and the outer wall are separated by one building module 1 as an example, in the gap space 11 formed by building modules CB1 and CB2, plane 6A is the outer wall, plane 6B is the inner wall, and the gap space 11 is connected, forming two openings 6a and 6b. Please refer to... Figure 6a In one possible implementation, the number of joint structures 2 is one, which is located near the opening 6a, and the location of the joint structure 2 and the sealing structure 3 is intended to waterproof the exterior wall. Please refer to... Figure 6b In another possible implementation, the number of joint structures 2 is one, located near the opening 6b. The joint structure 2 and the sealing structure 3 are positioned to ensure waterproofing of the interior wall. Please refer to [link / reference]. Figure 6c In another possible implementation, two joint structures 2 and two sealing structures 3 are provided, one joint structure 2 is located near 6a and the other is located near the opening 6b, and the sealing structures are respectively filled by the openings 6a and 6b. The positioning of the joint structures 2 and the sealing structures 3 is intended to waterproof both the inner and outer walls at the same time.

[0073] To resolve the above issues, please refer to Figure 7 The second embodiment of the present invention also provides a jointing method applied to the above-mentioned building structure 100, comprising the following steps:

[0074] S1 offers multiple building modules and joint structures;

[0075] S2, installs a joint structure on the surface of the building module based on a preset installation position;

[0076] S3, splicing multiple building modules with corresponding joint structures to form gap spaces;

[0077] S4, based on the preset installation position, fills the gap space with a sealing structure to prevent water from entering the gap space.

[0078] I understand, please refer to the above as well. Figure 1 During the assembly of building modules 1, gap spaces 11 will exist. Building structure 100 can typically be divided into interior walls and exterior walls. The gap spaces 11 can connect the interior and exterior walls. The interior and exterior walls may be separated by only one building module 1, or they may be separated by multiple building modules 1. When water comes into contact with the exterior or interior walls, it can easily seep into the gaps. In the process of assembling the building structure 100 using the jointing method of this embodiment, multiple building modules 1 and joint structures 2 are first provided. Then, the joint structures 2 are installed on the surface of the building modules 1 based on preset installation positions. It should be noted that each building module 1 has six faces. If it is to be assembled with multiple building modules 1, the number of assembled building modules 1 should correspond to the number of joint structures 2. Specifically, two adjacent building modules 1 require one joint structure 2. Therefore, if all six faces of a building module 1 need to be assembled, six joint structures 2 are required. Multiple building modules 1 are assembled to form the gap spaces 11. Then, based on the preset installation position, a sealing structure 3 is filled into the gap space 11 to prevent water from entering the gap space 11. It should be understood that the sealing structure 3 can form a waterproof measure, while the joint structure 2 can form another waterproof measure. With the combined effect of the two waterproof measures, water cannot enter the gap space 11 from the gap opening of the outer or inner wall, thus preventing seepage.

[0079] Specifically, the joint structure 2 includes at least two fasteners 21 and a receiving element 22, forming the gap space 11, which specifically includes the following steps:

[0080] S31, the fasteners are installed onto the surfaces of multiple building modules based on preset installation positions;

[0081] S32, which connects fasteners installed on the surfaces of different building modules to a support to splice multiple building modules.

[0082] Understandably, after the building module 1 is manufactured, the fastener 21 can be installed on its surface. The preset installation position refers to the location where the fastener 21 is installed on the surface of the building module 1. Referring to the figure, since the joint structure 2 has two waterproofing measures, it can be positioned close to the opening 12. The beneficial effect is that the sealing structure 3 only needs to fill the space from the end of the fastener 21 near the opening 12 to the opening 12. That is, the joint space on the side of the joint structure 2 away from the opening 12 does not need to be filled with the sealing structure 3. This approach can significantly reduce the amount of sealing structure 3 used, saving costs. After installation on the surface of the building module 1, the splicing work can be carried out accordingly. The splicing operation can be completed by connecting the fasteners 21 on different building modules 1 using the connector 22, which is simple and convenient.

[0083] Compared with the prior art, the building structure and joint method provided by the present invention have the following beneficial effects:

[0084] 1. An embodiment of the present invention provides a building structure comprising at least two building modules, a joint structure, and a sealing structure; the two building modules are spaced apart to form a gap space, with the connection between the gap space and the outside being an opening; the joint structure includes at least two fasteners and a receiving member, the two fasteners being disposed within the gap space and respectively connected to the two building modules; the sealing structure is disposed within the gap space near the opening and connected to the end of the fasteners near the opening; the receiving member is sandwiched between the two fasteners and detachably connected to the fasteners, forming a waterproof cavity with the fasteners to prevent external water from seeping into the gap space. The sealing structure and waterproof cavity in the building structure provided in this embodiment can effectively block water from entering the gap space, thereby solving the problems of short waterproof life and poor waterproof effect in existing building structures.

[0085] 2. The fastener of this invention includes a main body segment, a snap-fit ​​segment, and a connecting segment. Snap-fit ​​segments are provided at both ends of the main body segment. One side of the main body segment can contact the surface of the building module within the gap space, and the other side is provided with a connecting segment. The end of the connecting segment away from the connection with the main body segment is bent towards the opening to form a connecting groove. The connection between the fastener and the building module can be completed simultaneously during the factory prefabrication of the building module. That is, the building module can be shipped together with the fastener, saving significant installation time and improving assembly efficiency during the assembly of the building modules into a building structure.

[0086] 3. In this embodiment of the invention, the receiving component is a U-shaped channel. The U-shaped channel defines the interior and the outer surface of the U-shaped channel. The interior of the U-shaped channel can be used to collect water, and the opposite ends of the outer surface of the U-shaped channel are provided with support arms. The opening of the U-shaped channel needs to be provided with a corresponding opening so that the waterproof cavity formed can collect water that seeps in through the opening.

[0087] 4. The connecting groove and the support arm of the present invention cooperate to realize the detachable connection of the fixing part and the receiving part, which is simple and convenient.

[0088] 5. In this embodiment of the invention, a first damping element is provided in the connecting groove, and a second damping element is provided on the side of the support arm away from the U-shaped groove opening. When the connecting groove and the support arm are engaged, the first damping element and the second damping element come into contact. The contact between the first damping element and the second damping element allows them to provide each other with a large damping force, increasing friction and making the connection between the fixing element and the receiving element tighter. Secondly, it can improve the airtightness of the waterproof cavity, thereby improving the waterproof effect.

[0089] 6. The sealing structure of this embodiment includes a sealing layer and a grout layer. The sealing layer is disposed within the joint space, with one side connected to the end of the snap-fit ​​section near the opening, and the other side connected to the grout layer. The sealing layer can be a polyethylene rod. The polyethylene rod is used to fill the space from the joint structure to the opening to prevent water, dust, pollutants, etc., from entering the concrete through the opening.

[0090] 7. In this embodiment of the invention, the end of the sealing layer away from the mud layer has an accommodating space between it and the receiving component, which increases the capacity of the waterproof cavity and thus helps to improve the waterproof performance of the building structure.

[0091] 8. The joint structure of this embodiment of the invention also includes bolts, which penetrate the main body section near the connecting section and connect to the building module, thereby enhancing the tightness of the connection between the fastener and the building module.

[0092] 9. This embodiment of the invention also provides a jointing method, which has the same beneficial effects as the above-described building structure, and will not be described in detail here.

[0093] The foregoing has provided a detailed description of a building structure and joint method disclosed in the embodiments of the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention. Any modifications, equivalent substitutions, and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
