Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a dry concrete sleeve tenon and mortise connection integrated modular building system. Background Technology

[0002] Traditional solutions to building durability issues include high-density concrete, rust inhibitors, steel reinforcement coatings, or stainless steel. However, in island and reef environments, material transportation costs are high, construction periods are long, and the construction environment is harsh. Therefore, this invention utilizes basalt fiber composite reinforcement combined with an integrated modular building system, providing a new method for solving building durability problems in island and reef environments. Integrated modular buildings are a highly integrated and efficient building form that integrates all building elements, including structure, interior and exterior decoration, electromechanical systems, water supply and drainage, and HVAC, making them suitable for resource-scarce island and reef construction. However, existing integrated modular systems mostly use steel structures or cast-in-place concrete structures. Steel structures have drawbacks such as poor durability and comfort, while cast-in-place concrete structures require on-site secondary reinforcement binding and concrete pouring, placing high demands on site conditions.

[0003] There is currently no effective solution to the above problems. Utility Model Content

[0004] In response to the aforementioned technical problems in related technologies, this utility model proposes a dry concrete sleeve tenon and mortise connection integrated modular building system. The concrete structure can ensure the durability of the building in the island environment, the integrated modular building can solve the problem of resource scarcity in island and reef construction, and the dry tenon and mortise connection and concrete sleeve connection can solve the problem of steel corrosion, thus overcoming the above-mentioned shortcomings of the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows: A dry concrete sleeve tenon and mortise connection integrated modular building system includes a top slab, a bottom slab, and several boxes integrated by L-shaped shear walls and partition walls at the four corners. The wall reinforcement of the L-shaped shear walls consists of several vertical main load-bearing steel bars and several horizontal structural steel bars. The L-shaped shear walls are provided with connection notches at the upper and lower ends of the main load-bearing steel bars and at the outer ends of the structural steel bars.

One of the aligned connecting recesses is provided with a threaded end corresponding to the wall reinforcement. The bottom of the other aligned connecting recess is flush with the bottom end of the corresponding wall reinforcement. The threaded end of the wall reinforcement is fitted with a high-performance concrete connecting kit. Ultra-high performance concrete is poured between the aligned connecting recesses.

[0006] Furthermore, the L-shaped shear wall has an upper connecting notch at the upper end of the main reinforcing bar, and a lower connecting notch at the lower end of the main reinforcing bar. The upper connecting notch contains the threaded end of the main reinforcing bar, and the bottom of the lower connecting notch is flush with the end of the corresponding main reinforcing bar.

[0007] Furthermore, the main reinforcing bars are made of basalt fiber composite reinforcement, and the main reinforcing bars are provided at the turning point of the L-shaped shear wall. The main reinforcing bars on the two walls of the L-shaped shear wall are arranged in a single row in the center.

[0008] Furthermore, the L-shaped shear wall has a horizontal box-shaped connection notch at the outer end of the structural reinforcement. When the horizontal boxes are assembled, the horizontal box-shaped connection notches are aligned with each other. The structural reinforcement on one of the horizontal box-shaped connection notches has the threaded end, and the end of the structural reinforcement on the other horizontal box-shaped connection notch is flush with the bottom of the corresponding horizontal box-shaped connection notch.

[0009] Furthermore, the high-performance concrete connection kit is provided with a stainless steel internal threaded sleeve that connects to the threaded end of the wall reinforcement.

[0010] Furthermore, the high-performance concrete connection kit has a rubber sealing ring fitted at the bottom end of the corresponding connection recess.

[0012] Furthermore, the partition wall integrates doors, windows, water and electricity systems.

[0013] Furthermore, the partition wall is made of lightweight foamed concrete, and the reinforcement of the top and bottom slabs is made of basalt reinforcement.

[0014] The beneficial effects of this utility model are as follows: This utility model adopts factory-integrated production and processing. The box body is made of basalt reinforcement and lightweight foamed concrete integrally cast, ensuring the integrity of the box body and having sufficient rigidity. The horizontal and vertical connections between the boxes are all connected using standard high-performance concrete kits. The horizontal force between the boxes is transmitted through the friction and mechanical interlocking force formed by the kit and the notch, improving the overall performance of the structure and enabling the simultaneous transmission of horizontal loads in two directions. This invention has a high degree of assembly, enabling factory production of integrated structure and decoration, and a high degree of standardization, allowing for diverse combinations between boxes. This invention fully utilizes the high strength and corrosion resistance of basalt reinforcement, and the structure can achieve free assembly of low-rise buildings, basically solving the durability problem of buildings in harsh island and reef environments. This invention uses a combination of basalt fiber composite reinforcement and lightweight foamed concrete to solve the problem of the heavy weight of traditional concrete integrated modular walls and the need for large machinery for transportation and hoisting.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0028] In practical application, according to the dry concrete sleeve tenon and mortise connection integrated modular building system described in this utility model, the main load-bearing structure of the modular box 5 adopts an L-shaped shear wall 2 structure, the main load-bearing steel bars 6 are large-diameter basalt fiber composite bars with threads left on the top, the wall limbs of the L-shaped shear wall 2 have pre-reserved tenon and mortise notches, and the connecting dry concrete kit is made of high-performance concrete pre-embedded internal thread sleeves.

[0029] The integrated modular enclosure 5 is manufactured in the factory, with doors, windows, water and electricity systems, and interior decoration all installed and interfaces pre-installed. Enclosure 5 measures 3m x 6m. Its main load-bearing structure consists of four L-shaped shear walls 2 at the corners, featuring mortise and tenon joints and a wall thickness of 200mm. The remaining partition walls 3 are integrally cast using PFC lightweight foamed concrete with embedded basalt fiber reinforcement.
