Description

Technical Field

[0001] This invention application relates to the field of prefabricated building technology, specifically to a connection structure and assembly method for prefabricated strip wall panels and frames. Background Technology

[0002] Prefabricated buildings transfer a large amount of on-site construction work, such as beams, columns, and walls, to component factories. This enables large-scale, standardized mass production of building structural components and offers significant technological advantages over traditional cast-in-place structures in terms of improved production efficiency, reduced production costs, component quality control, and centralized pollution treatment.

[0003] The assembly and connection methods between prefabricated walls and the main frame structure mainly include external hanging and embedded types. These assembly structures and methods have two main problems: First, there are many gaps between the prefabricated walls and the main frame structure, especially through gaps, which leads to more work required for subsequent surface smoothing of the interior and exterior walls and for breaking thermal bridges between the interior and exterior, increasing labor costs and extending the construction period. Second, in the event of a major earthquake, the prefabricated walls are difficult to coordinate with the deformation of the main frame. If the wall stiffness is too high, it is easy to cause shear failure at the column top or column base, resulting in brittle failure of the entire structure. If the wall stiffness is too low, it is easy to cause local wall collapse. Both are the main causes of casualties and property damage during earthquakes.

[0004] To address the aforementioned issues, the inventors believe that a novel connection method should be adopted between the prefabricated wall and the main frame structure. On the one hand, it is necessary to ensure that the prefabricated building has good energy-saving and thermal insulation performance; on the other hand, it is necessary to ensure a reliable connection between the prefabricated wall and the main frame structure, and to minimize the number of steps in the building assembly process.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0011] In some embodiments of this disclosure, the cross-section of the A-type, C-type, and D-type connecting snap-fit ​​compartments is an isosceles right triangle, with the side entering the snap-fit ​​compartment rounded and the interior of the snap-fit ​​compartment treated as a right angle; the B-type and E-type connecting snap-fit ​​compartments are provided with a sealing pad on the side opposite to the column side reinforcement, the sealing pad being provided along the entire length from the top to the bottom of the main frame column, and horizontal stiffening ribs are provided on the side at the same position as the column side reinforcement, spaced apart from top to bottom.

[0012] In some embodiments of this disclosure, the type A, type B, type C, type D, and type E connecting clips are made of plastic materials such as PP, PE, or PS.

[0013] According to another aspect of this disclosure, a method for assembling prefabricated strip wall panels and frames is provided, implemented based on the above-described connection structure, comprising the following steps: S1. In the installation of the main frame columns at the external corner and the main frame columns at the flat corner, the prefabricated strip wall panels are hoisted to the design position between the two installed main frame columns in the order from bottom to top. Then, the pre-embedded steel bars at the ends of the prefabricated strip wall panels are connected to the steel bars on the side of the columns by threaded sleeves. At the same time, the end sealing pads of the end wing plates are pressed and squeezed tightly with the main frame columns. After all the pre-embedded steel bars at the ends of each prefabricated strip wall panel are connected, the assembly construction of the next prefabricated strip wall panel can be carried out. S11. After the prefabricated strip wall panels within each clear height range are assembled, hoist the Type B exterior wall panels to the design position, and make the side of each Type B exterior wall panel with the snap-on tongue face the direction of the prefabricated strip wall panel. Use pressing or a soft hammer to push the snap-on tongue of the Type B exterior wall panel into the Type B connecting snap-on compartment on the main frame column and into the wall panel connecting snap-on compartment on the prefabricated strip wall panel, thus completing the assembly of the Type B exterior wall panel. S111, In the relevant installation of the main frame column at the external corner, the A-type external wall panel is hoisted to the design position. First, the adhesive is evenly applied to the end of the A-type external wall panel, and the spring clips at both ends of each A-type external wall panel are pushed into the A-type connecting clip compartment on the main frame column. The end of the A-type external wall panel is then pressed and squeezed tightly with the end of the B-type external wall panel to complete the assembly of the A-type external wall panel. S112, In the relevant installation of the main frame column at the flat corner, the C-shaped outer wall panel is hoisted to the design position. First, the adhesive is evenly applied to the end of the C-shaped outer wall panel, and the spring clips at both ends of each C-shaped outer wall panel are pushed into the C-shaped connecting clip compartment on the main frame column. The end of the C-shaped outer wall panel is then pressed and squeezed tightly with the end of the B-shaped outer wall panel to complete the assembly of the C-shaped outer wall panel. S2, In the installation of the main frame column at the inside corner, first hoist the D-type outer wall panel to the design position, push the spring clips at both ends of each D-type outer wall panel into the D-type connection clip compartment on the main frame column, and then assemble and connect the prefabricated strip wall panel with the main frame column. The end pre-embedded steel bars and the column side steel bars are connected by threaded sleeves. After the prefabricated strip wall panels in each clear height range are assembled, install the B-type outer wall panel, so that the clips of each B-type outer wall panel are pushed into the E-type connection clip compartment on the main frame column and the wall panel connection clip compartment on the prefabricated strip wall panel respectively, to complete the assembly of the B-type outer wall panel; S3. After the assembly of the prefabricated strip wall panels and the outer wall panels is completed, the prepared post-pouring material is pumped into the building interior through the discharge pipe. It is injected into the cavity between the prefabricated strip wall panels, the main frame columns, and the B-type outer wall panels through the U-shaped groove on the end wing plate of the topmost prefabricated strip wall panel within each clear height range. The B-type outer wall panels are used as permanent templates. After solidification, a wall with good sealing and thermal insulation performance is formed.

[0014] One or more technical solutions provided in the embodiments of this application have at least one of the following technical effects or advantages: 1. Since all exterior wall panels are manufactured according to exterior wall design and standardization, they possess all the functions of exterior walls, such as heat insulation, waterproofing, and moisture-proofing. They can be used directly as permanent exterior walls of buildings, reducing the number of steps in the building assembly process and improving work efficiency.

[0015] 2. Because the prefabricated strip wall panels have grooves and protrusions at the top and bottom respectively, during the assembly process, the grooves and protrusions between the upper and lower prefabricated strip wall panels cooperate with each other. When subjected to a large horizontal earthquake exceeding the design standard, a slight horizontal sliding can occur between the grooves and protrusions between the upper and lower prefabricated strip wall panels in each floor. This horizontal sliding can increase the inter-story deformation capacity of the structure and avoid shear failure at the column base or column top.

[0016] 3. Because the main frame columns and prefabricated strip wall panels are equipped with column side reinforcement and end embedded reinforcement, and the column side reinforcement and end embedded reinforcement are connected by threaded sleeves, the assembly is not only simple and efficient, but also has strong tensile strength, which can prevent the prefabricated strip wall panels from collapsing under a major earthquake, effectively protecting people's lives and property. In addition, the main frame columns and prefabricated strip wall panels have good sealing performance and good thermal insulation performance.

[0017] 4. Since the post-pouring material is poured indoors through a U-shaped channel, while the Type A and Type C exterior wall panels are installed outdoors, the pouring of the post-pouring material and the installation of the Type A and Type C exterior wall panels can be carried out simultaneously after the Type B exterior wall panels are installed, without causing any harmful effects. This effectively shortens the construction period and improves assembly efficiency.

[0018] 5. Since the post-cast material fills the cavity between the main frame columns and the prefabricated strip wall panels, and both the post-cast material and the outer wall panels can be designed with systematic and differentiated insulation, the assembled building has significant technical advantages in terms of airtightness and insulation performance.

[0019] 6. Because the dovetail groove is provided on the inner side of the Type B exterior wall panel, it has a strong bonding effect with the post-cast material. Under the combined effect of this bonding effect and the connecting buckles at both ends of the prefabricated strip wall panel, the integrity of the exterior wall panel, the post-cast material and the prefabricated strip wall panel are effectively guaranteed, thereby avoiding the adverse phenomenon of separation and detachment from the exterior wall that may occur after long-term operation of traditional exterior wall insulation layer.

[0031] Unless otherwise specified, the components, structures, and mechanisms involved in the following embodiments are all commercially available products.

[0032] Example 1 This example discloses a connection structure between a prefabricated strip wall panel and a frame. See [link / reference] Figure 1-5 It includes the main frame columns, prefabricated strip wall panels 4, external wall panels and post-cast materials; the main frame columns have a rectangular cross-section and are prefabricated in the factory and transported to the construction site for assembly. Based on the relative position of the prefabricated strip wall panels and the main frame columns in the building, the main frame columns that need to be assembled with wall panels can be divided into three types: main frame columns at the external corner 1, main frame columns at the flat corner 2 and main frame columns at the internal corner 3; the external wall panels can be structurally divided into type A external wall panels 5, type B external wall panels 6, type C external wall panels 7, and type D external wall panels 8.

[0033] See Figure 1 , Figure 6At the external corner, the main frame column 1 is equipped with a type A connecting clip 9, a type B connecting clip 10, and column side reinforcement 14. The type A connecting clip 9 is located on two adjacent sides connected to the type A outer wall panel 5. Its cross-sectional outline is an isosceles right triangle, with the side entering the clip being rounded and the interior of the clip being right-angled. The type B connecting clip 10 and column side reinforcement 14 are located on two adjacent sides connected to the prefabricated strip wall panel 4. The type B connecting clip 10 has a sealing pad 16 on the side opposite to the column side reinforcement 14. The sealing pad 16 extends from the top of the main frame column. The B-type connecting clip 10 is installed along its entire length. On the same side as the column side reinforcement 14, there is a horizontal stiffening rib 17. The horizontal stiffening rib 17 is made of the same material as the B-type connecting clip 10 and is arranged at intervals from top to bottom to enhance the connection rigidity between the B-type connecting clip 10 and the main frame column. The column side reinforcement 14 is arranged at equal intervals from top to bottom on the side of the main frame column where the wall panel needs to be assembled. The column side reinforcement 14 is reliably connected to the main frame column by pre-embedding or welding. Threads and threaded sleeves 15 are provided at the extended ends of the column side reinforcement 14 for connection with the prefabricated strip wall panel.

[0034] See Figure 7 At the flat corner, the main frame column 2 is equipped with a C-type connecting clip 11, a B-type connecting clip 10, and column side reinforcement 14. The C-type connecting clip 11 is located on a single side connected to the C-type outer wall panel 7, and its cross-sectional outline is rectangular, with the side entering the clip being rounded, and the interior of the clip being right-angled. The B-type connecting clip 10 and column side reinforcement 14 are located on two symmetrical sides connected to the prefabricated strip wall panel 4. See also... Figure 8 At the internal corner, the main frame column 3 is equipped with a D-type connecting clip 12, an E-type connecting clip 13, and column side reinforcement 14. The D-type connecting clip 12 is located on a single right angle connected to the D-type outer wall panel 8. Its cross-sectional outer contour is a double isosceles right triangle. The side entering the clip is rounded, and the inside of the clip is a right angle. The E-type connecting clip 13 and column side reinforcement 14 are located on two adjacent sides connected to the prefabricated strip wall panel. The right angle formed by these adjacent sides is the right angle where the D-type connecting clip 12 is located. The E-type connecting clip 13 has the same structure and auxiliary components as the B-type connecting clip 10.

[0035] Type A connecting clip compartment 9, Type B connecting clip compartment 10, Type C connecting clip compartment 11, Type D connecting clip compartment 12, and Type E connecting clip compartment 13 are all made of plastic materials such as PP, PE, or PS with good heat insulation, durability, and certain strength, and are reliably connected to the main frame column through embedded parts or welded parts.

[0036] See Figure 2The prefabricated strip wall panel 4 is a strip wall panel designed for easy transportation, hoisting, and assembly. From the outside in, it consists of a surface layer 18, an insulation layer 19, a wall panel adhesive layer 20, a wall panel connection clip 21, end embedded steel bars 22, and end flanges 23. It has a top groove 24 and a bottom protrusion 25. The wall panel connection clip 21 is located at both ends of the prefabricated strip wall panel 4, and its structure and auxiliary components are consistent with the type B connection clip 10. The end embedded steel bars 22 are reliably connected to the prefabricated strip wall panel 4 through pre-embedding or welding, and their extended ends are threaded for connection with the threaded sleeves 15 of the column-side steel bars 14. The end flanges 23 are located at both ends of the prefabricated strip wall panel 4 and have end sealing pads 26 on them. When the prefabricated strip wall panel 4 is assembled with the main frame column, the end flanges 23 are connected to the main frame through the end sealing pads 26. The column abuts, presses, and seals. The end flange of the top prefabricated strip wall panel on each floor is provided with a U-shaped groove 27 for pouring post-cast material. The end flange 23 can act as a permanent formwork when pouring post-cast material. There are two grooves 24 at the top and two protrusions 25 at the bottom. The grooves 24 at the top and the protrusions 25 at the bottom of the two prefabricated strip wall panels can be connected. When assembling the wall panels, a layer of mortar about 10mm thick is filled between the upper and lower adjacent prefabricated strip wall panels 4 for masonry. When subjected to a large horizontal earthquake exceeding the design standard, a slight horizontal sliding can occur between the grooves and protrusions of the upper and lower prefabricated strip wall panels in each floor. This horizontal sliding can increase the inter-story deformation capacity of the structure and avoid shear failure at the column base or column top. The groove formed by the bottom protrusion of the bottom prefabricated strip wall panel at the bottom of each floor is used for burying pipelines.

[0037] See Figure 1 Type A exterior wall panel 5, Type B exterior wall panel 6, and Type C exterior wall panel 7 are respectively provided with an exterior wall surface layer 28, an exterior wall insulation layer 29, and an exterior wall structural layer 30 from the outside to the inside. Type D exterior wall panel 8 is provided with an exterior wall insulation layer 29 and an exterior wall structural layer 30 from the outside to the inside. Type A exterior wall panel 5 has a right-angled cross-section, and its two ends are provided with spring-loaded latches 31 that can cooperate with Type A connecting latches 9 for connection. The spring-loaded latches 31 are split arrow-shaped with a spring in the middle. See also Figure 3 , Figure 4The B-type exterior wall panel 6 and the C-type exterior wall panel 7 have rectangular cross-sections. The B-type exterior wall panel 6 has a dovetail groove 32 on its inner side, which provides strong adhesion between the B-type exterior wall panel 6 and the post-cast material. The dovetail groove 32 has snap-fit ​​tongues 33 on both sides for connecting with the B-type connecting snap-fit ​​compartment 10, the E-type connecting snap-fit ​​compartment 13, and the wall panel connecting snap-fit ​​compartment 21. The B-type exterior wall panel 6 serves as the outer formwork for the post-cast material, tightly fitting with the main frame columns and prefabricated strip wall panels 4 to form a cavity for pouring the post-cast material. The C-type exterior wall panel 7 has spring snap-fit ​​tongues 31 on its inner ends for connecting with the C-type connecting snap-fit ​​compartment 11. (See also...) Figure 5 The cross-section of the D-type outer wall panel 8 is an isosceles right triangle structure, and its inclined surface is provided with a spring buckle tongue 31, which is used to cooperate with the D-type connecting buckle compartment 12 for connection.

[0038] The exterior wall panels and prefabricated strip wall panels reliably connect the exterior wall surface layer, exterior wall insulation layer and exterior wall structural layer using wire mesh and cross diagonal ribs. The exterior wall surface layer can be painted or decorated with bricks. The exterior wall panels and prefabricated strip wall panels integrate waterproof, moisture-proof and other exterior wall functions and can be used as permanent exterior walls.

[0039] The base material of the post-cast material is mainly foamed concrete with good workability. To improve its thermal insulation performance, loose thermal insulation particles such as polystyrene particles or vitrified microsphere particles can be added as lightweight aggregates. During construction, the post-cast material can be transported in the order of "spiral mixer, extrusion pump, screw pump, and discharge pipe". It is injected into the cavity between the prefabricated strip wall panel 4, the B-type outer wall panel 6 and the main frame column through the U-shaped groove 27 on the end wing wall of the topmost prefabricated strip wall panel in each net height range. The B-type outer wall panel 6 is used as a permanent template. After solidification, a wall with good sealing and thermal insulation performance is formed.

[0040] Example 2 This example discloses a method for assembling prefabricated strip wall panels and frames, implemented based on the connection structure described in Embodiment 1, including the following steps: S1, see S1 Figure 6 , Figure 7 During the installation of the main frame columns at the external and internal corners, the prefabricated strip wall panels are first horizontally hoisted to the designed position between the two pre-installed main frame columns in a bottom-up sequence. Then, a special tool is used to connect the pre-embedded steel bars at the ends of the prefabricated strip wall panels with the steel bars on the side of the columns through threaded sleeves. At the same time as the threaded sleeves are connected, the sealing pads at the ends of the prefabricated strip wall panel flanges are pressed and squeezed tightly against the main frame columns. After all the pre-embedded steel bars at the ends of each prefabricated strip wall panel are connected, about 10mm of mortar is applied near the top groove before the assembly of the next prefabricated strip wall panel can begin.

[0041] S11. After the prefabricated strip wall panels within each clear height range are assembled, hoist the Type B exterior wall panels to the designed position, and ensure that the side of each Type B exterior wall panel with the connecting clip tongue faces the direction of the prefabricated strip wall panel. Use pressing or a soft hammer to push the connecting clip tongue of the Type B exterior wall panel into the Type B connecting clip compartment on the main frame column and into the wall panel connecting clip compartment on the prefabricated strip wall panel, thus completing the assembly of the Type B exterior wall panel.

[0042] S111, during the installation of the main frame column at the external corner, the type A outer wall panel is hoisted to the design position. First, the adhesive is evenly applied to the end of the type A outer wall panel, and the spring clips at both ends of each type A outer wall panel are pushed into the type A connecting clip compartment on the main frame column. The end of the type A outer wall panel is then pressed and squeezed tightly with the end of the type B outer wall panel to complete the assembly of the type A outer wall panel.

[0043] S112, during the installation of the main frame column at the flat corner, the C-shaped outer wall panel is hoisted to the design position. First, the adhesive is evenly applied to the end of the C-shaped outer wall panel, and the spring clips at both ends of each C-shaped outer wall panel are pushed into the C-shaped connecting clip compartment on the main frame column. The end of the C-shaped outer wall panel is then pressed and squeezed tightly with the end of the B-shaped outer wall panel to complete the assembly of the C-shaped outer wall panel.

[0044] S2, see S2. Figure 8 In the installation of the main frame columns at the inside corners, the D-type exterior wall panels are first hoisted to the designed position. The spring clips at both ends of each D-type exterior wall panel are pushed into the D-type connecting clip compartments on the main frame columns. Then, the prefabricated strip wall panels are assembled and connected to the main frame columns. The pre-embedded steel bars at the ends are threadedly connected to the steel bars on the column sides through threaded sleeves. After the prefabricated strip wall panels within each clear height range are assembled, the B-type exterior wall panels are installed. The connecting clips of each B-type exterior wall panel are pushed into the E-type connecting clip compartments on the main frame columns and the wall panel connecting clip compartments on the prefabricated strip wall panels, thus completing the assembly of the B-type exterior wall panels.

[0045] S3. After the assembly of the outer wall panel and the prefabricated strip wall panel is completed, the prepared post-pouring material is pumped into the building interior through the discharge pipe. It is injected into the cavity between the end of the prefabricated strip wall panel and the main frame column through the U-shaped groove on the end wing wall of the topmost prefabricated strip wall panel in each clear height range. The B-type outer wall panel is used as a permanent template. After solidification, a wall with good sealing and thermal insulation performance is formed.

In the installation of the main frame columns at the external corner and the main frame columns at the flat corner, the prefabricated strip wall panels are hoisted to the design position between the two installed main frame columns in the order from bottom to top. Then, the pre-embedded steel bars at the ends of the prefabricated strip wall panels are connected to the steel bars on the side of the columns by threaded sleeves. At the same time, the end sealing pads of the end wing plates are pressed and squeezed tightly with the main frame columns. After all the pre-embedded steel bars at the ends of each prefabricated strip wall panel are connected, the assembly construction of the next prefabricated strip wall panel can be carried out. S11. After the prefabricated strip wall panels within each clear height range are assembled, hoist the Type B exterior wall panels to the design position, and make the side of each Type B exterior wall panel with the snap-on tongue face the direction of the prefabricated strip wall panel. Use pressing or a soft hammer to push the snap-on tongue of the Type B exterior wall panel into the Type B connecting snap-on compartment on the main frame column and into the wall panel connecting snap-on compartment on the prefabricated strip wall panel, thus completing the assembly of the Type B exterior wall panel. S111, In the relevant installation of the main frame column at the external corner, the A-type external wall panel is hoisted to the design position. First, the adhesive is evenly applied to the end of the A-type external wall panel, and the spring clips at both ends of each A-type external wall panel are pushed into the A-type connecting clip compartment on the main frame column. The end of the A-type external wall panel is then pressed and squeezed tightly with the end of the B-type external wall panel to complete the assembly of the A-type external wall panel. S112, In the relevant installation of the main frame column at the flat corner, the C-shaped outer wall panel is hoisted to the design position. First, the adhesive is evenly applied to the end of the C-shaped outer wall panel, and the spring clips at both ends of each C-shaped outer wall panel are pushed into the C-shaped connecting clip compartment on the main frame column. The end of the C-shaped outer wall panel is then pressed and squeezed tightly with the end of the B-shaped outer wall panel to complete the assembly of the C-shaped outer wall panel. S2, In the installation of the main frame column at the inside corner, first hoist the D-type outer wall panel to the design position, push the spring clips at both ends of each D-type outer wall panel into the D-type connection clip compartment on the main frame column, and then assemble and connect the prefabricated strip wall panel with the main frame column. The end pre-embedded steel bars and the column side steel bars are connected by threaded sleeves. After the prefabricated strip wall panels in each clear height range are assembled, install the B-type outer wall panel, so that the clips of each B-type outer wall panel are pushed into the E-type connection clip compartment on the main frame column and the wall panel connection clip compartment on the prefabricated strip wall panel respectively, to complete the assembly of the B-type outer wall panel; S3. After the assembly of the prefabricated strip wall panels and the outer wall panels is completed, the prepared post-pouring material is pumped into the building interior through the discharge pipe. It is injected into the cavity between the prefabricated strip wall panels, the main frame columns, and the B-type outer wall panels through the U-shaped groove on the end wing plate of the topmost prefabricated strip wall panel within each clear height range. The B-type outer wall panels are used as permanent templates. After solidification, a wall with good sealing and thermal insulation performance is formed.
