Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically a prefabricated wall. Background Technology

[0002] Precast walls, as a major component of prefabricated monolithic shear wall structures, are frequently used in residential projects. Commonly used precast walls include precast sandwich insulated walls, precast interior wall panels, and PCF panels.

[0003] However, the following problems were found in the implementation of the relevant technologies:

[0004] During the process of prefabricated walls being formed in the factory and assembled on site, it is necessary to consider not only the structural issues during installation but also the structural load-bearing issues during transportation. For example, it functions as a wall during assembly but as a horizontally placed slab during transportation and hoisting. Existing prefabricated wall structures only consider the wall's load-bearing capacity and do not reasonably expand its structural load-bearing capacity under different conditions. Therefore, this utility model was developed to address this need. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a prefabricated wall that is more adaptable to various scenarios and structurally stable.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated precast wall, comprising at least two precast wall bodies, characterized in that: a main rib support and two auxiliary rib supports are provided along the wall height direction within the precast wall body, and the auxiliary rib supports are mirror images of the main rib support on both sides; the main rib support is located in the middle area of ​​the precast wall body;

[0007] The main rib support includes several main rib pillars, and the several main rib pillars form at least two rows of main rib pillar groups. Each row of main rib pillar groups is connected by main rib horizontal pillars. Adjacent rows of main rib pillar groups are connected by multiple main rib side pillars arranged along the column height direction. Adjacent main rib oblique pillars are intersected between adjacent main rib side pillars.

[0008] The auxiliary rib support includes several auxiliary rib pillars, and the several auxiliary rib pillars form at least two rows of auxiliary rib pillar groups. Each row of auxiliary rib pillar groups is connected by auxiliary rib horizontal pillars. Adjacent rows of auxiliary rib pillar groups are connected by multiple auxiliary rib side pillars arranged along the pillar height direction. Adjacent auxiliary rib oblique pillars are intersected between adjacent auxiliary rib side pillars.

A plurality of large reinforcing grooves are opened on one side of the reinforcing plate, and a plurality of small reinforcing grooves are opened on the other side of the reinforcing plate.

[0011] Preferably, the large reinforcing groove and the small reinforcing groove of the reinforcing plate are arranged back to back, and the length direction of the large reinforcing groove and the small reinforcing groove is perpendicular to the arrangement direction of the main rib support and the auxiliary rib support.

[0012] Preferably, there are at least two vertically arranged reinforcing plates, with a frame fixedly provided on the lower surface of the reinforcing plate and a strip fixedly provided on the upper surface of the reinforcing plate, and the strips of adjacent reinforcing plates are inserted into the corresponding frames.

[0013] Preferably, L-shaped connecting strips are symmetrically fixed on the upper surface of the uppermost insert and the lower surface of the lowermost insert frame, and the L-shaped connecting strips are fixedly connected to the corresponding main rib bracket or the auxiliary rib bracket.

[0014] Preferably, a splicing frame is fixedly provided on one side of the prefabricated wall, and a T-shaped slot is provided on one side of the splicing frame. A T-shaped clip is fixedly connected to the other side of the prefabricated wall, and the T-shaped clips of adjacent prefabricated walls are engaged in the corresponding T-shaped slots.

The fixing plate and the splicing frame are connected by bolts.

[0016] Preferably, the precast wall has plaster layers formed on both sides.

[0017] Preferably, the main rib support has eight main rib pillars, which are arranged in a rectangular array to form four rows of main rib pillar groups. The auxiliary rib support has four auxiliary rib pillars, which are arranged in a rectangular array to form two rows of auxiliary rib pillar groups.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. When prefabricated wall panels are hoisted and transported, the concentrated load is greatest in the middle area. The structure formed by the main rib support and the auxiliary rib support of this utility model forms rigid support in the area with large concentrated load. The main rib support and the auxiliary rib support themselves serve as the vertical internal structural keel of the wall, which not only meets the needs of flat placement or hoisting, but also conforms to the strength design of the wall.

By rationally designing the number and distribution of the main rib supports, as well as the setting of diagonal columns and vertical reinforcement columns, the entire structure can withstand a large load. It is suitable for building sites with high requirements for floor load-bearing capacity, such as commercial buildings and industrial plants.

[0022] 3. The triangular structure centered on the reinforced ball joint inside the support frame and the connection method between the various components enhance the stability of the structure. All of these factors ensure good coordination between the parts and prevent deformation or damage when bearing loads, thereby improving the safety and durability of the building structure.

[0023] 4. This utility model, through the splicing design of T-shaped clips and T-shaped slots, and the reinforcement method of fixing plates, makes the splicing process of adjacent precast walls simple and quick, reducing on-site construction time and workload. This convenient splicing method helps improve construction efficiency and reduce construction costs, and is especially suitable for large-scale construction projects. Attached Figure Description

[0037] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0038] like Figures 1 to 6 As shown, this utility model provides a prefabricated wall assembly, including at least two prefabricated wall bodies 1, wherein a main rib support 2 and two auxiliary rib supports 3 are provided along the wall height direction inside the prefabricated wall body 1, and the auxiliary rib supports 3 are mirror images of the main rib support 2 on both sides; the main rib support 2 is located in the middle area of ​​the prefabricated wall body 1.

[0039] Furthermore, the main rib support 2 includes several main rib pillars 21, which form at least two rows of main rib pillar groups 21. Each row of main rib pillar groups 21 is connected by main rib cross pillars 22. Adjacent rows of main rib pillar groups 21 are connected by multiple main rib side pillars 23 arranged along the column height direction. Adjacent main rib side pillars 23 are intersected by main rib diagonal pillars 24. The auxiliary rib support 3 includes several auxiliary rib pillars 31, which form at least two rows of auxiliary rib pillar groups 31. Each row of auxiliary rib pillar groups 31 is connected by auxiliary rib cross pillars 32. Adjacent rows of auxiliary rib pillar groups 31 are connected by multiple auxiliary rib side pillars 33 arranged along the column height direction. Adjacent auxiliary rib side pillars 33 are intersected by auxiliary rib diagonal pillars 34. Both the upper and lower ends of the main rib pillars 21 and the auxiliary rib pillars 31 are fixedly provided with bolts 7.

[0040] Specifically, there are eight main rib supports 21 in the main rib support 2, and the eight main rib supports 21 are arranged in a rectangular array to form four rows of the main rib supports 21; in view of the arrangement of the main rib supports 21, there are four auxiliary rib supports 31 in the auxiliary rib support 3, and the four supports are arranged in a rectangular array to form two rows of the auxiliary rib supports 31.

[0041] A reinforcing ball joint 4 is provided at the intersection of the intersecting main rib oblique column 24 and the intersecting auxiliary rib oblique column 34. A main rib vertical column 25 is provided between the main rib side column 23 and the reinforcing ball joint 4. An auxiliary rib vertical column 35 is provided between the auxiliary rib side column 33 and the reinforcing ball joint 4.

[0042] The main rib support 2 and the auxiliary rib support 3 constitute the main support frame of the precast wall 1. The eight main rib supports 21 in the main rib support 2 are distributed in a rectangular shape, and the four auxiliary rib supports 31 in the auxiliary rib support 3 are also distributed in a rectangular shape.

[0043] These main rib supports 21 are interconnected through main rib horizontal columns 22, main rib side columns 23, main rib diagonal columns 24, and main rib vertical columns 25, forming a stable triangular spatial structure. When bearing loads, the supports work together to distribute the load to various parts of the precast wall 1. Utilizing the stability principle of triangular structures (such as the triangular structure formed by the main rib diagonal column 24, main rib side columns 23, and main rib vertical columns 25), the overall load-bearing capacity of the structure is enhanced. The bolts 7 at the upper and lower ends of the main rib supports 21 help to fix the position of the main rib supports 2 when the precast wall 1 is cast, and to a certain extent, enhance the connection strength between the upper and lower surfaces of the precast wall 1 and the main rib supports 2, thereby improving the overall collaborative performance.

[0044] Similarly, the auxiliary rib support 31 is interconnected through the auxiliary rib horizontal column 32, auxiliary rib side column 33, auxiliary rib diagonal column 34 and auxiliary rib vertical column 35 to form a stable triangular spatial structure. When bearing load, each support works together to distribute the load to various parts of the precast wall 1. Utilizing the stability principle of the triangular structure (such as the triangular structure formed by the auxiliary rib diagonal column 34, auxiliary rib side column 33 and auxiliary rib vertical column 35), the overall load-bearing capacity of the structure is enhanced. The bolts 7 at the upper and lower ends of the auxiliary rib support 31 help to fix the position of the auxiliary rib support 3 when the precast wall 1 is cast and formed, and to a certain extent enhance the connection strength between the upper and lower surfaces of the precast wall 1 and the auxiliary rib support 3, thereby improving the overall collaborative performance.

[0045] Specifically, several reinforcing plates 5 are symmetrically arranged inside the precast wall 1, and the reinforcing plates 5 are located between the main rib support 2 and the auxiliary rib support 3. Several large reinforcing grooves 51 are opened on one side of the reinforcing plate 5, and several small reinforcing grooves 52 are opened on the other side of the reinforcing plate 5. The reinforcing plates 5 are distributed between the main rib support 2 and the auxiliary rib support 3. The large reinforcing grooves 51 and small reinforcing grooves 52 on both sides reduce their own weight. On the other hand, the reasonable distribution of grooves optimizes the stress performance of the reinforcing plates 5. When the precast wall 1 is under load, the reinforcing plates 5 can share part of the load and transfer it to the support structure, thereby improving the load-bearing capacity and stability of the entire precast wall 1. While reducing their own weight, the large reinforcing grooves 51 and small reinforcing grooves 52 on the reinforcing plates 5 ensure the strength and rigidity of the reinforcing plates 5 through reasonable structural design. The weight reduction will not affect their reinforcing effect on the precast wall 1. At the same time, this design optimizes the performance of the entire wall, reduces the amount of material used while ensuring the load-bearing capacity, and achieves a balance between economic benefits and structural performance.

[0046] Furthermore, the large reinforcing groove 51 and the small reinforcing groove 52 of the reinforcing plate 5 are arranged back-to-back, and the length direction of the large reinforcing groove 51 and the small reinforcing groove 52 is perpendicular to the arrangement direction of the main rib support 21 and the auxiliary rib support 31. The large reinforcing groove 51 and the small reinforcing groove 52 form a groove-rib structure, which is perpendicular to the vertically arranged main rib support 2 and auxiliary rib support 3, forming the internal structural support of the precast wall 1 in a longitudinal and transverse arrangement.

[0047] Furthermore, at least two reinforcing plates 5 are vertically arranged between the main rib support 2 and the auxiliary rib support 3. A frame 54 is fixedly provided on the lower surface of each reinforcing plate 5, and a strip 53 is fixedly provided on the upper surface of each reinforcing plate 5. The strips 53 of adjacent reinforcing plates 5 are inserted into the corresponding frames 54, thus facilitating adaptability to walls of different heights. L-shaped connecting strips 55 are symmetrically fixed on the upper surface of the uppermost strip 53 and the lower surface of the lowermost frame 54, and the L-shaped connecting strips 55 are fixedly connected to the corresponding main rib support 2 or auxiliary rib support 3.

[0048] In a preferred embodiment of this invention, there can be multiple prefabricated walls 1, which are assembled by splicing. Specifically, a splicing frame 6 is fixedly provided on one side of the prefabricated wall 1, and a T-shaped slot 61 is provided on one side of the splicing frame 6. A T-shaped clip 62 is fixedly connected to the other side of the prefabricated wall 1, and the T-shaped clip 62 is engaged in the corresponding T-shaped slot 61. The T-shaped clip 62 on one side of the prefabricated wall 1 cooperates with the T-shaped slot 61 on the splicing frame 6 on the other side to realize the rapid splicing of the prefabricated walls 1. This splicing method allows multiple prefabricated walls 1 to be easily combined into a large-area wall panel structure to meet the needs of different building spaces. The plaster layer 11 on both sides of the prefabricated wall 1 plays a protective and decorative role, and at the same time enhances the surface strength and integrity of the prefabricated wall 1 to a certain extent, making the floor surface smoother and more beautiful, and improving the overall quality of the building.

[0049] It is worth noting that the lower surface of the reinforcing plate 5 is fixedly provided with a frame 54, and the upper surface of the reinforcing plate 5 is fixedly provided with a strip 53, and the strip 53 is inserted into the corresponding frame 54. The strip 53 and the frame 54 on the reinforcing plate 5 cooperate with each other, so that multiple reinforcing plates 5 can be connected in sequence to form an integral reinforcing system.

[0050] It is worth emphasizing that the upper side of the splicing frame 6 is provided with a fixing plate 63, and the lower surface of the fixing plate 63 is fixed with a T-shaped card block 64. The T-shaped card block 64 is inserted into the corresponding T-shaped slot 61. The fixing plate 63 and the splicing frame 6 are connected by bolts. The fixing plate 63 on the splicing frame 6 is inserted into the T-shaped slot 61 through the T-shaped card block 64 and connected to the splicing frame 6 with bolts, which further enhances the connection strength at the splicing point and ensures that the splicing part will not easily separate during use.

[0051] Structural principle: The main rib support 2 and the auxiliary rib support 3 constitute the main support frame of the precast wall 1. The eight main rib supports 21 in the main rib support 2 are distributed in a rectangular shape, and the four auxiliary rib supports 31 in the auxiliary rib support 3 are also distributed in a rectangular shape. These supports are connected to each other through horizontal columns, side columns, diagonal columns and vertical columns to form a stable spatial structure. When bearing load, each support works together to distribute and transfer the load to various parts of the precast wall 1. The stability principle of triangular structure (such as the triangular structure formed by diagonal columns, side columns and vertical reinforcing columns) is used to enhance the load-bearing capacity of the overall structure.

[0052] The reinforcing plate 5 is distributed between the main rib support 2 and the auxiliary rib support 3. The large reinforcing groove 51 and the small reinforcing groove 52 opened on both sides reduce its own weight and optimize the stress performance of the reinforcing plate 5 through reasonable groove distribution. The insert strip 53 and the insert frame 54 on the reinforcing plate 5 cooperate with each other, so that multiple reinforcing plates 5 can be connected in sequence to form an integrated reinforcing system. The L-shaped connecting strip 55 on the uppermost insert strip 53 and the lowermost insert frame 54 are fixedly connected to the main rib support 2 or the auxiliary rib support 3, which further enhances the collaborative working ability between the reinforcing plate 5 and the support. When the precast wall 1 bears a load, the reinforcing plate 5 can share part of the load and transfer it to the support structure, thereby improving the load-bearing capacity and stability of the entire precast wall 1.

[0053] The T-shaped clip 62 on one side of the prefabricated wall 1 cooperates with the T-shaped slot 61 on the splicing frame 6 on the other side to realize the rapid splicing between the prefabricated wall 1. The fixing plate 63 on the splicing frame 6 is inserted into the T-shaped slot 61 through the T-shaped clip 64 and connected to the splicing frame 6 with bolts, which further enhances the connection strength at the splicing point and ensures that the splicing part will not easily separate during use. This splicing method allows multiple prefabricated wall 1 to be easily combined into a large-area wall panel structure to meet the needs of different building spaces.

[0054] The beneficial effects of this embodiment:

[0055] 1. When prefabricated wall panels are hoisted and transported, the concentrated load is greatest in the middle area. The structure formed by the main rib support 2 and the auxiliary rib support 3 of this utility model forms rigid support in the area with large concentrated load. The main rib support 2 and the auxiliary rib support 3 themselves serve as the vertical internal structural keel of the wall, which not only meets the needs of flat placement or hoisting but also conforms to the strength design of the wall.

[0056] 2. The reinforcing plate 5, which is set perpendicular to the main rib support 2, forms a longitudinal and transverse rib structure. When laid flat or hoisted, it forms a two-way plate, which also improves the structural strength during installation and greatly enhances the load-bearing capacity of the wall. By rationally designing the number and distribution of the main rib support 21, as well as the setting of diagonal columns, vertical reinforcing columns, etc., the entire structure can withstand a large load. It is suitable for building sites with high requirements for floor load-bearing capacity, such as commercial buildings and industrial plants.

[0057] 3. The triangular structure centered on the reinforced ball joint 4 inside the support frame and the connection method between various components enhance the stability of the structure. All of these factors ensure good coordination between the parts and prevent deformation or damage when bearing loads, thereby improving the safety and durability of the building structure.

[0058] 4. This utility model, through the splicing design of T-shaped clips 62 and T-shaped slots 61, and the reinforcement method of fixing plates 63, makes the splicing process of adjacent precast wall sections 1 simple and quick, reducing on-site construction time and workload. This convenient splicing method helps to improve construction efficiency and reduce construction costs, and is especially suitable for large-scale construction projects.

[0059] Furthermore, the present invention has been described in detail above with reference to the accompanying drawings and embodiments.
