In this embodiment, as shown in fig. 2 and 3, the new high-rise concrete modular building is designed in such a way that the modular units 1 are combined to form the frame 2 to be connected. In the building process, different module units 1 can be selected according to actual needs to be combined so as to meet building requirements of different scenes and requirements. The edges of each module unit 1 are uniformly distributed with a plurality of L-shaped bi-directional grooves 3, and the number, position and size of the L-shaped bi-directional grooves 3 are carefully designed so that an optimal matching effect can be achieved when connecting.
In the assembly process, the module units 1 are combined as required to form the frame 2 to be connected. The outer edges of the frames 2 to be connected are flush in order to better connect other modular units 1 or to connect with other structures. The L-shaped bi-directional grooves 3 of the module units 1 adjacent in the vertical direction are also aligned to ensure the connection firmness and the firmness of the overall structure. When all the modular units 1 are connected, a complete building structure system is formed.

The existence of the reinforcing steel bars enables the connection point to be firmer, and can bear larger load and action. The design not only improves the stability and the anti-seismic performance of the whole structure, but also can effectively prevent the structure from displacement or deformation.
In addition, the provision of the longitudinal additional reinforcing bars 5 can also improve the overall strength and durability of the building. The addition of the reinforcing steel bars can enhance the tensile capacity of the concrete and effectively resist the influence of external impact and action. Therefore, the novel edge connection method of the high-rise concrete modularized building has the characteristics of convenience, high efficiency and stability, and the safety of the building is guaranteed.
103. An outer wall panel 4 is arranged outside the edge of the module unit 1; a certain gap exists between the module unit 1 and the exterior wall panel 4. As shown in fig. 2 and 4, in the novel high-rise concrete modular building of the present embodiment, in order to increase the external appearance aesthetic property and thermal insulation performance of the building, an exterior wall panel 4 is provided outside the edge of the module unit 1. The exterior wall panel 4 can be prefabricated decorative wall board or heat insulation board material, etc., and in practical application, exterior wall panels 4 with different materials or appearances can be selected according to practical needs.
In this embodiment, a certain gap exists between the module unit 1 and the outer wall panel 4 for subsequent concrete casting in the gap, so as to improve the stability and safety of the overall structure of the building. It should be noted that during the design and construction process, the size of the gap between the module unit 1 and the exterior wall panel 4 must be reasonably controlled to ensure that the exterior wall panel 4 can be properly and firmly installed on the modular building, while ensuring the overall performance and protection effect of the building structure. In the present embodiment, the clearance between the module unit 1 and the exterior wall panel 4 is in the range of 80 to 120mm.
104. And (3) pouring concrete after adding a reinforcement cage with the shape matched with the shape of the gap in the gap, so that adjacent module units 1 and the outer wall panels 4 are fused into an integral structure, and the edge connection of the frame 2 to be connected is completed. In order to complete the edge connection of the frames 2 to be connected, a reinforcement cage adapted to the shape of the gap can be added in the gap between the module unit 1 and the exterior wall panel 4. The design of steel reinforcement cage can be carried out according to the specific circumstances, adopts vertically and horizontally staggered mode generally to increase the intensity and the stability of structure.
Firstly, according to the design requirement and the structural strength requirement of the frame 2 to be connected, a reinforcement cage which is suitable for the gap shape is manufactured. The reinforcement cage may be made using prefabricated rebar pieces or by machining and assembling the rebar in the field. Ensuring that the size, the number and the arrangement of the reinforcement cages meet the design requirements.
Then, a reinforcement cage is placed in the gap between the module unit 1 and the exterior wall panel 4. The reinforcement cage should completely fill the gap and be closely attached to the module unit 1 and the exterior wall panel 4. This ensures the adhesion and the connection strength between the reinforcing steel bars and the concrete.
And finally, after the reinforcement cage is placed, pouring concrete. The concrete is poured uniformly into the gap, filling the entire space, and ensuring that the concrete covers the surfaces of the reinforcement cage and the module unit 1 and the outer wall panel 4. After the concrete is poured, the concrete is fully vibrated and compacted so as to ensure the quality and strength of the concrete.
By adding the reinforcement cage with the shape matched with the gap in the gap and pouring concrete, the adjacent module units 1 and the outer wall panel 4 can be fused into an integral structure. The connecting mode can increase the overall rigidity and stability of the frame 2 to be connected, and improve the earthquake resistance and wind resistance of the building. Meanwhile, the bearing capacity of the connecting part can be enhanced by adding the reinforcement cage, and the safety and reliability of the building structure are ensured.
In one embodiment, the modular unit 1 comprises a plurality of different types, the different types of modular units 1 being the same in height and the exterior wall panels 4 being the same in height as the modular units 1.
In the present embodiment, the module unit 1 is diversified, including a plurality of different types of modules. Although these module units 1 are of different types, their heights are identical to ensure that the heights of the module units 1 and the exterior wall panels 4 match each other.
Different types of modular units 1 may have different functions and uses, such as living rooms, bedrooms, kitchens, etc. Their design and size may be varied to meet different space requirements and functional requirements. However, in order to achieve edge connection and form an integral structure, the heights of these module units 1 need to be kept uniform.
In addition, the height of the exterior wall panel 4 is the same as that of the module unit 1, so that the connection between the exterior wall panel 4 and the module unit 1 can be ensured to be flat and tight. This conforming design can provide a visually uniform appearance and ensures the stability and structural integrity of the connection site.
By maintaining the same height in the module units 1 having different types, and using the exterior wall panels 4 matched to the module units 1, the coordination and consistency of the overall building can be achieved. The design not only makes the appearance of the building more uniform and beautiful, but also can simplify the construction process and improve the structural performance and stability of the building. Meanwhile, by connecting the module unit 1 with the edge of the outer wall panel 4, a compact integral structure can be formed, the earthquake resistance and wind resistance of the building are enhanced, and a safer and more reliable living environment is provided.
In a specific embodiment, a plurality of L-shaped bidirectional grooves 3 are uniformly formed on the edge of the outer wall panel 4; the L-shaped bi-directional grooves 3 of the upper and lower adjacent exterior wall panels 4 disposed outside the edges of the module units 1 are aligned.
In this embodiment, in order to achieve connection of the module unit 1 and the exterior wall panel 4, a plurality of L-shaped bidirectional grooves 3 are provided on the edge of the exterior wall panel 4, which are uniformly distributed. These L-shaped bi-directional grooves 3 are aligned with the outside of the edges of the modular unit 1.
Each of the exterior wall panels 4 has a plurality of L-shaped bi-directional grooves 3 on its edges, the number, shape and size of which can be designed according to specific requirements to correspond to the edges of the modular units 1, thereby achieving their tight connection and stable fixation.
This arrangement provides a reliable connection, with the modular unit 1 and the exterior wall panel 4 forming a unitary structure. Through the alignment of the L-shaped bidirectional grooves 3, the connecting part can bear load and stress better, and the stability and the structural strength of the building are enhanced. At the same time, the design also facilitates the installation and the disassembly of the module unit 1, and improves the construction efficiency and the flexibility.
In practical applications, the L-shaped bidirectional grooves 3 may take different shapes, such as wedge-shaped, rectangular or triangular, etc., so as to adapt to different architectural designs and requirements.
The wedge-shaped L-shaped bi-directional groove 3 is shaped like an inverted triangle with a narrower width, providing a tighter connection and greater stability. The rectangular L-shaped bi-directional recess 3 is shaped like a rectangle with a length that is balanced compared to the width, providing smoother connection and wider applicability. The triangular L-shaped bidirectional groove 3 is similar to a regular triangle in shape, and the sharp corner position can provide better fixing force and anti-skid performance.
Whichever shape of the L-shaped bi-directional groove 3 is used, it is necessary to ensure alignment with the L-shaped bi-directional groove 3 of the modular unit 1 and the exterior wall panel 4 and provide proper connection and stability. And meanwhile, the durability, the safety and other factors of the materials are required to be considered so as to ensure the structural strength and the safety performance of the building.
This design may provide a flexible choice to accommodate different architectural designs and requirements. The tight connection of the module unit 1 and the outer wall panel 4 can be realized no matter what shape of the L-shaped bidirectional groove 3 is adopted, thereby improving the stability and the structural strength of the building.
In a specific embodiment, the end part of the L-shaped bidirectional groove 3 is provided with a through hole, and the prestress rib 7 is arranged in the L-shaped bidirectional groove 3 in the two adjacent module units 1 in a penetrating way;
the through holes are penetrated in the L-shaped bidirectional grooves 3 of the upper and lower adjacent outer wall panels 4 to place prestressed tendons 7.
Further, in this embodiment, as shown in fig. 5, by forming a through hole at the end of the L-shaped bi-directional groove 3 and placing the tendon 7 therein through the through hole, tight connection between the adjacent module units 1 and the adjacent exterior wall panels 4 can be further achieved. The connecting mode is simple and reliable, and has high shear strength and tensile strength.
In the installation process, the two ends of the prestressed tendons 7 are tensioned to apply the pretightening force. The magnitude of the preload force may be determined based on specific design requirements and structural load carrying capacity. The prestress force is used for enabling the prestress rib 7 to be subjected to tensile force, and a mechanical balance state for resisting load is formed in the wall structure. The combination between the upper wall body and the lower wall body is tighter through the tensioning of the prestressed tendons 7 and the application of the pretightening force. Therefore, the rigidity and stability of the whole structure can be effectively improved, and the possibility of deformation and cracking of the wall body is reduced. Meanwhile, the prestressed tendons 7 can play an anchoring role when the wall body is subjected to external force, so that the wall body can better resist the load. The stability and bearing capacity of the whole structure are improved, and the service life of the structure is prolonged.
In a word, through penetrating the through hole in the two-way recess of L type and placing prestressing tendons 7 to exert the pretightning force, can improve wall structure's stability and bearing capacity effectively. The technology has wide application prospect in building engineering and can provide powerful guarantee for the safety and reliability of the building.

The thickness of each mould shell ranges from 60 mm to 80mm, and the thickness can be adjusted according to specific conditions so as to meet the requirements of building structures and heat insulation. The thickness of the outer wall panel 4 is also in the range of 60 to 80mm, which matches the thickness of the module unit 1. Such a design ensures a high degree of consistency between the modular unit 1 and the exterior wall panel 4, thereby achieving a tight connection and a flat appearance.
A gap is left between the module unit 1 and the exterior wall panel 4, and the gap is in the range of 80 to 120mm. The size of the gap can be adjusted according to the building design and the requirement to provide proper gaps, so that the reinforcement cage can be conveniently added into the gap and concrete can be poured. Through the gap between the module unit 1 and the exterior wall panel 4, ventilation and heat insulation effects can also be achieved. In practical applications, the gap can also be used for installing insulating materials or filling sound insulation materials according to practical requirements so as to improve the heat insulation performance and the acoustic performance of the building.
The design not only can realize the stable connection of the module unit 1 and the outer wall panel 4, but also can provide heat insulation and sound insulation effects while guaranteeing the stability of the building structure. Such modular building design can improve construction efficiency, reduce energy consumption, and provide a comfortable and environmentally friendly living environment.

In this embodiment, as shown in fig. 5, in order to further enhance structural stability and durability of the modular building, in addition to connecting the exterior wall panels 4 with the module units 1 using the L-shaped bi-directional groove 3, a water stop steel plate 6 is provided at the seam of the upper and lower adjacent two exterior wall panels 4 toward the side of the module units 1. The concrete exterior wall panel 4 may have a single-plate shape as shown in fig. 4 or an L-shape as shown in fig. 6.
The function of the water stop steel plates 6 is to fix the adjacent module units 1, the exterior wall panels 4 and the water stop steel plates 6 as an integral structure after casting concrete, thereby effectively preventing infiltration and leakage of water. The water-stop steel sheet 6 is made of high-quality steel, has excellent corrosion resistance and durability, and can maintain its function and appearance for a long period of time.
When the water stop steel plate 6 is provided, it is necessary to ensure that it matches the size and position of the module unit 1, the exterior wall panel 4, and provide suitable fixing and sealing performance. At the same time, compatibility and safety of the water stop steel plate 6 with other building materials are also required to be considered so as to ensure the overall structure and performance of the building.
By adopting the water stop steel plate 6, penetration and leakage of water can be effectively prevented, thereby improving durability and stability of the modular building. The design scheme can meet different building requirements and demands, and provides important support and guarantee for the realization of the modularized building.
In a specific embodiment, the method further comprises:

The sealant is a material having excellent elasticity and adhesion properties, and can fix and seal adjacent building members together, effectively preventing penetration and leakage of moisture, air and dust. In this embodiment, the sealant is used at the joint of the two upper and lower adjacent exterior wall panels 4 at the side far from the module unit 1 to fill the joint and form a completely sealed structure.
In performing the sealing process, it is necessary to select the appropriate sealant material and tools to ensure that the sealant is a close fit with the exterior wall panels 4 and other building components and provide a durable and reliable sealing effect. Meanwhile, attention is paid to the use environment and safety performance of the sealant so as to ensure that the building structure and personnel health are not negatively affected.
By adopting the sealant for sealing treatment, the penetration and leakage of moisture, air and dust can be effectively prevented, so that the waterproof performance and sealing performance of the modularized building are improved. The design scheme can meet different building requirements and demands, and provides important support and guarantee for the realization of the modularized building.
In a specific embodiment, the method further comprises:
on the outer wall formed by the outer wall panels 4, water guide pipes are arranged at cross joints formed by the junctions of a plurality of outer wall panels 4 at certain intervals;
the water guide pipe is connected to the cross joint through sealing glue.
In this embodiment, in order to further enhance the waterproof performance and the drainage function of the modular building, in addition to the water stop steel plate 6 and the sealing treatment using the sealant, a water guide pipe is provided at the cross joint formed at the boundary of the plurality of exterior wall panels 4 on the exterior wall formed by the exterior wall panels 4.
The purpose of the water guide pipes is to collect and guide rainwater or other moisture from the cross-joint of the exterior wall panel 4 to reduce moisture accumulation and prevent leakage. The water guides are arranged at a distance apart to ensure effective coverage of the entire surface of the exterior wall panel 4 and to form a continuous drainage system.
When the water guide pipe is arranged, accurate calculation and layout are required according to actual conditions so as to ensure that the junction of the water guide pipe and the outer wall panel 4 is matched and a smooth water flow channel is provided. In addition, in order to ensure firm connection and sealing performance of the water guide pipe, sealing glue is also required to be used for sealing connection between the water guide pipe and the cross joint.
By arranging the water guide pipe and using the sealant for sealing connection, rainwater or other moisture can be effectively guided and discharged, moisture accumulation is reduced, and leakage is prevented. The design scheme not only improves the waterproof performance of the modularized building, but also enhances the drainage function of the modularized building, thereby further protecting the stability and durability of the building structure.
In a specific embodiment, the method further comprises:
the installation angle of the water guide pipe is 30-45 degrees relative to the outer wall panel 4.
In the present embodiment, in order to secure the drainage effect of the water guide pipe and the convenience of operation, it is also necessary to install the water guide pipe within an angle range, typically between 30 ° and 45 °, with respect to the exterior wall panel 4.
By installing the water guide pipe at a certain inclination angle on the exterior wall panel 4, it is possible to effectively promote smooth flow of water and to prevent accumulation or backflow of water in the pipe. When installing the aqueduct, accurate measurement and adjustment of the angle are required according to specific conditions to ensure that the inclination angle of the aqueduct and the exterior wall panel 4 is within a required range. Meanwhile, attention is paid to the fixing and connection of the water guide pipe, so that the stability and the sealing performance of the water guide pipe are ensured, and accidental loosening or water leakage is prevented.
By installing the water guide pipe in a proper angle range, a good water discharge effect can be ensured, thereby further improving the waterproof performance of the modular building. The design scheme can effectively cope with rainwater drainage under different weather conditions, protect building structures from being damaged by moisture, and improve the service life and reliability of the building structures.
In a specific embodiment, the concrete comprises C40 concrete or C50 concrete; the higher the height, the larger the diameter of the corresponding additional rebar.
In this embodiment, C40 concrete or C50 concrete is often used as a main component material in the structural design of a modular building. The concrete grades have higher strength and durability and can meet the bearing requirements of buildings.
For modular buildings of different heights, the diameters of the corresponding additional bars will also vary. Generally, as the height increases, the diameter of the corresponding additional rebar also increases to enhance the load carrying capacity and stability of the structure. This design takes into account the mechanical properties and load bearing requirements of the building structure. By increasing the diameter of the additional reinforcing steel bars, the tensile strength, the compressive strength and the shear strength of the concrete structure can be effectively improved, so that the overall stability of the building is enhanced.
In practical application, the specifications of the additional steel bars and the steel bar cages need to be calculated and determined according to the height and design load of the building and the related specifications and standards of the reinforced concrete structure. This ensures the rationality and safety of the structural design, enabling the modular building to withstand the loads of various mechanical and environmental conditions, and maintain long-term structural stability.
In general, the selection of appropriate concrete grades and corresponding additional rebar diameters are important considerations in modular building structural design, which together ensure the strength, stability and durability of the building.
