Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to a connection structure between a building roof and a building wall panel. Background Art

[0002] The roof and walls are key components of a building's interior structure. The roof, located at the top of the building, provides cover and support for the upper floors. Walls, perpendicular to the ground, connect to the roof, providing stability and dividing space. Together, these two structures form the foundational framework of the interior environment.

[0003] After extensive searching, the publication number CN219732346U discloses a connection structure between a building roof and a building wall panel. By setting a connecting plate, the stability between the building roof panels is improved and the connection strength between the building roof panels and the building wall panels is enhanced; by setting a connecting frame, the connection between the building wall panels and the building roof panels is fixed to improve the stability between the building wall panels and the building roof panels; by setting a connecting anchor block, the connection between the building roof and the building wall panels is made more stable.

[0004] However, during actual assembly, the effects of thermal expansion and contraction on structural stability must be considered. For example, when the temperature rises, the material expands, causing compression between structural components; when the temperature drops, the material contracts, potentially creating gaps between components. These factors can affect structural stability. The structures in the referenced documents fail to consider this aspect, necessitating a new structure for connecting the roof and wall panels to address this issue. Utility Model Content

[0005] The purpose of the utility model is to provide a connection structure between a building roof and a building wall panel, which has the advantages of being stable and adaptable to temperature changes, and solves the problem that thermal expansion and contraction may affect the stability of the structure.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a connecting structure between a building roof and a building wall panel, comprising a wall panel, a connecting piece movably inserted on the top of the wall panel, a roof panel movably connected to both sides of the top of the connecting piece, the connecting piece comprising a plug-in frame, limit plates welded to the front and rear ends of the plug-in frame, the plug-in frame adopts a T-shaped structural design, and a limit protrusion is welded to the middle of the upper end surface of the plug-in frame;

[0007] There are two top plates, and splicing grooves are respectively opened on both sides of the lower end surfaces of the two top plates. The two top plates are respectively spliced and installed with connecting parts through the splicing grooves. Reserved grooves are respectively opened on both sides of the upper end surfaces of the two top plates, and pull rods are movably inserted in the adjacent reserved grooves in the two top plates.

[0008] Preferably, the top longitudinal cross-section of the wall panel features a tapered structure with slots for insertion. The bottom of the wall panel is cast with equidistant bumps, whose width matches the distance between the two opposing top panels. The unique tapered top design of the wall panel not only enhances the mechanical properties of the wall panel but also provides a precise interface with the connectors through the slots. The tapered bottom of the wall panel features equidistant bumps, whose width matches the distance between the opposing top panels, ensuring a tight fit between the bottom and top panels and overall structural stability.

[0009] Preferably, the bottom of the connector bracket is movably inserted into the slot, with the bottom of each side of the bracket not in contact with the slot interior and the gap filled with concrete of higher strength than the wallboard. The connector's bracket is designed to flexibly fit into the slot at the top of the wallboard, allowing for a degree of adjustment to accommodate minor deviations during on-site installation. The bottom of each side of the bracket remains free of contact with the slot interior, while the gap between them is filled with concrete of higher strength than the wallboard. This design provides additional support and enhances the stability of the connection, ensuring the reliability of the structure under load.

[0010] Preferably, the two limiting plates have opposing sides that contact the outer walls of the wall panels and roof panels, respectively, but are not fixedly connected, and the top height of the two limiting plates is lower than the top height of the roof panel. In this design, the opposing sides of the two limiting plates can contact the outer walls of the wall panels and roof panels, respectively, but are not fixedly connected. This non-fixed connection provides a certain degree of flexibility to the structure, allowing for minor deformations caused by temperature changes. The top height of the limiting plates is lower than the top height of the roof panel. This design ensures an effective connection between the roof panels while allowing for a certain amount of displacement to reduce the impact of thermal expansion and contraction on structural stability.

[0011] Preferably, the longitudinal cross-section of the limiting protrusion adopts an isosceles triangle structure, and the bottom width of the limiting protrusion matches the distance between the two opposite sides of the top plate. The limiting protrusion adopts an isosceles triangle structure in the design, which is mechanically stable and can provide an effective limiting effect. The bottom width of the limiting protrusion matches the distance between the opposite sides of the top plate, ensuring the stable positioning of the top plate on the connector and enhancing the rigidity and load-bearing capacity of the overall structure.

[0012] Preferably, the reserved grooves have limit holes, into which the ends of the tie rods are inserted. In this design, the reserved grooves on both sides of the top plate have limit holes, into which the ends of the tie rods are inserted. This design allows the tie rods to provide additional connection and fixation to adjacent top plates, enhancing the integrity and shear resistance of the top plates.

[0013] Preferably, the tie rod adopts a U-shaped structural design, with a short anchor rod welded to the middle of the lower end surface of the tie rod. The short anchor rod is located on opposite sides of the two top plates and directly above the limit protrusion. The tie rod adopts a U-shaped structural design in the design. This shape is simple and effective, and easy to install and adjust. The short anchor rod is welded to the middle of the lower end surface of the tie rod. The short anchor rod is located on opposite sides of the two top plates and directly above the limit protrusion. This layout provides an additional anchor point for the structure, enhancing the stability and reliability of the connection.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The movable plug-in connector on the top of the wall panel of this utility model allows a certain degree of displacement, providing the necessary flexibility for assembly, the T-shaped plug-in frame provides a solid support, the design of the limit plate and the limit protrusion ensures the stable positioning of the top plate on the connector, and at the same time their structural design allows partial absorption of deformation during thermal expansion and contraction, reducing the impact on structural stability, the reserved grooves set on the top plate and the movable plug-in pull rod provide additional connection and fixation, enhancing the integrity and shear resistance of the top plate, and at the same time the U-shaped structural design of the pull rod and the anchoring short rod provide additional anchoring points, enhancing the stability of the connection Qualitatively, the gap between the bottom of the plug-in frame and the plug-in slot is filled with concrete, which has a stronger strength than the wall panel. This design provides additional support and stability. At the same time, the concrete has a low coefficient of thermal expansion and contraction, which helps to reduce the deformation of the overall structure caused by temperature changes. The tapered structure design at the top of the wall panel and the plug-in slot provide structural stability. At the same time, the tapered structure can provide a certain amount of space during thermal expansion and contraction, reducing the impact on structural stability. The T-shaped connection structure design allows for a more stable connection between the top plate and the wall panel. At the same time, this structure also helps to disperse the stress caused by temperature changes. Through the combined application of these design features, the connection structure can adapt to the expansion and contraction of the material due to temperature changes without sacrificing stability, thereby improving the overall performance and durability of the building. These designs not only take into account the mechanical properties of the structure, but also take into account the convenience and economy of construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1 to 6 As shown, the utility model provides an embodiment: a connection structure between a building roof and a building wall panel, including a wall panel 1, a connector 2 is movably inserted on the top of the wall panel 1, and a roof panel 3 is movably spliced on both sides of the top of the connector 2. The connector 2 includes a plug-in frame 21, and limit plates 23 are welded and installed at the front and rear ends of the plug-in frame 21. The plug-in frame 21 adopts a T-shaped structure design, and a limit protrusion 22 is welded and installed in the middle of the upper end surface of the plug-in frame 21;

[0026] There are two top plates 3, and splicing grooves 33 are respectively opened on both sides of the lower end surfaces of the two top plates 3. The two top plates 3 are respectively spliced and installed with the connecting parts 2 through the splicing grooves 33. Reserved grooves 32 are respectively opened on both sides of the upper end surfaces of the two top plates 3, and pull rods 31 are movably inserted in the adjacent reserved grooves 32 in the two top plates 3.

[0027] Specifically, the movable plug-in connector 2 on the top of the wall panel 1 allows a certain degree of displacement, providing the necessary flexibility for assembly, the T-shaped plug-in frame 21 provides a solid support, the design of the limit plate 23 and the limit protrusion 22 ensures the stable positioning of the top plate 3 on the connector 2, and at the same time their structural design allows partial absorption of deformation during thermal expansion and contraction, reducing the impact on structural stability, the reserved groove 32 set on the top plate 3 and the movable plug-in pull rod 31 provide additional connection and fixation, enhancing the integrity and shear resistance of the top plate 3, and the U-shaped structural design of the pull rod 31 and the anchoring short rod 301 provide additional anchoring points, enhancing In order to improve the stability of the connection, the gap between the bottom of the plug-in frame 21 and the plug-in slot 11 is filled with concrete with a strength higher than that of the wall panel 1. This design provides additional support and stability. At the same time, the thermal expansion and contraction coefficient of concrete is low, which helps to reduce the deformation of the overall structure caused by temperature changes. The conical structure design at the top of the wall panel 1 and the matching of the plug-in slot 11 provide structural stability. At the same time, the conical structure can provide a certain amount of space during thermal expansion and contraction, reducing the impact on structural stability. The design of the T-type connection structure allows the connection between the top plate 3 and the wall panel 1 to be more stable. At the same time, this structure also helps to disperse the stress caused by temperature changes. Through the comprehensive application of these design features, the connection structure can adapt to the expansion and contraction of materials caused by temperature changes without sacrificing stability, thereby improving the overall performance and durability of the building. These designs not only take into account the mechanical properties of the structure, but also take into account the convenience and economy of construction.

[0028] Example 2

[0029] In order to improve the stability of the connection structure between the wall panel and the connector, such as Figures 2 to 4 As shown, in this embodiment, the top longitudinal cross-section of the wall panel 1 adopts a conical structure design and is provided with a plug-in groove 11. The bottom of the wall panel 1 is cast with equidistant bumps 12, the width of which matches the distance between the two opposite sides of the top panels 3. The top of the wall panel 1 is designed as a conical structure. This unique design not only enhances the mechanical properties of the wall panel 1, but also provides an interface for precise docking with the connector 2 through the plug-in groove 11 provided at the top. The bottom of the conical wall panel 1 is cast with equidistant bumps 12, the width of which matches the distance between the opposite sides of the top panels 3, ensuring a tight fit between the bottom of the wall panel 1 and the top panels 3 and the overall stability of the structure.

[0030] Furthermore, the bottom of the plug-in frame 21 is movably inserted into the plug-in slot 11. The bottoms of both sides of the plug-in frame 21 do not contact the interior of the plug-in slot 11, and the gaps are filled with concrete with a strength higher than that of the wall panel 1. In the design, the plug-in frame 21 of the connector 2 is movably inserted into the plug-in slot 11 at the top of the wall panel 1. This design allows a certain degree of adjustment to accommodate minor deviations in on-site installation. The bottoms of both sides of the plug-in frame 21 do not contact the interior of the plug-in slot 11, and the gaps between them are filled with concrete with a strength higher than that of the wall panel 1. This design not only provides additional support but also enhances the stability of the connection, ensuring the reliability of the structure when bearing loads.

[0031] Example 3

[0032] In order to improve the stability of the connection structure between the top plate and the connector and increase the shear resistance of the overall structure, such as Figures 2 to 4 As shown, in this embodiment, the opposite sides of the two limit plates 23 are in contact with the outer walls of the wall panel 1 and the top panel 3 respectively, but are not fixedly connected. The top heights of the two limit plates 23 are lower than the top height of the top panel 3. In the design, the opposite sides of the two limit plates 23 can be in contact with the outer walls of the wall panel 1 and the top panel 3 respectively, but do not form a fixed connection. This non-fixed connection method provides a certain degree of flexibility for the structure to adapt to slight deformations caused by temperature changes. The top height of the limit plates 23 is lower than the top height of the top panel 3. This design not only ensures an effective connection between the top panels 3, but also allows a certain amount of displacement to reduce the impact of thermal expansion and contraction on the stability of the structure.

[0033] Furthermore, the longitudinal cross-section of the limiting protrusion 22 adopts an isosceles triangle structure, and the bottom width of the limiting protrusion 22 matches the distance between the two opposing sides of the top plates 3. The isosceles triangle structure of the limiting protrusion 22 is mechanically stable and provides effective positioning. The matching width of the bottom of the limiting protrusion 22 with the distance between the opposing sides of the top plates 3 ensures the stable positioning of the top plates 3 on the connector 2, enhancing the rigidity and load-bearing capacity of the overall structure.

[0034] Furthermore, the reserved groove 32 defines a limit hole 34, into which the ends of the tie rod 31 are inserted. In this design, the reserved groove 32 on both sides of the upper end surface of the top plate 3 defines a limit hole 34, into which the ends of the tie rod 31 are inserted. This design allows the tie rod 31 to provide additional connection and fixation to adjacent top plates 3, enhancing the integrity and shear resistance of the top plates 3.

[0035] Furthermore, the tie rod 31 adopts a U-shaped structural design, with a short anchor rod 301 welded to the middle of the lower end surface of the tie rod 31. The short anchor rod 301 is located on opposite sides of the two top plates and directly above the stop protrusion 22. The tie rod 31 adopts a U-shaped structural design, which is simple and effective, and easy to install and adjust. The short anchor rod 301 is welded to the middle of the lower end surface of the tie rod 31. The short anchor rod 301 is located on opposite sides of the two top plates 3 and directly above the stop protrusion 22. This layout provides an additional anchor point for the structure, enhancing the stability and reliability of the connection.

[0036] When the present invention is used, the wall panel 1 is placed in a predetermined position, ensuring that the protrusion 12 at its bottom is aligned with the foundation or lower structure, and the bottom of the plug-in frame 21 of the connector 2 is inserted into the plug-in slot 11 at the top of the wall panel 1, ensuring that the bottoms on both sides of the plug-in frame 21 do not contact the inside of the plug-in slot 11, and the gap is filled with concrete with a strength higher than that of the wall panel 1, and the splicing grooves 33 on both sides of the lower end faces of the two top plates 3 are aligned with the corresponding parts of the connector 2, thereby completing the splicing and installation with the connector 2, and limiting the distance between the opposite sides of the adjacent top plates 3 by the limiting protrusion 22, and opening a limiting hole 34 in the reserved slot 32 of the top plate 3, and inserting the two ends of the pull rod 31 into the limiting hole 34 respectively, thereby completing the splicing of the adjacent top plates 3. After all components are installed in place, make necessary adjustments to ensure that the connection between the connector 2 and the top plate 3 is stable, and use asphalt or other flexible materials with waterproof properties to fill the gaps after assembly to ensure the waterproof performance of each structural connection. Finally, check the entire connection structure to ensure that all components are correctly installed according to the design requirements, and make any necessary adjustments or reinforcements to ensure the integrity and safety of the structure. After the inspection is completed, conduct a final acceptance to ensure that the structure meets all design and safety standards.
