Description

Technical Field

[0001] The present invention relates to the technical field of house construction, and in particular to a house building wall structure and a construction method. Background Art

[0002] Traditional house building wall structures include concrete walls and masonry walls. Steel bars are pre-reserved or implanted in the areas of the concrete wall that are used to connect with the masonry wall. During the process of building the concrete wall to form the masonry wall, the steel bars are pressed into the gaps between the adjacent masonry blocks that make up the masonry wall, and then filled with mortar to connect the concrete wall to the masonry wall. Alternatively, the two ends of the L-shaped iron sheet are fixed to the lightweight blocks and the concrete main wall respectively by nailing, and then mortar is laid between the adjacent blocks. Both of the above methods can achieve the connection between the concrete wall and the masonry wall, but in the above methods, the mortar at the connection between the concrete wall and the masonry wall is very prone to cracking, making it difficult to ensure the coordinated force between the concrete wall and the masonry wall.

[0003] Patent "CN111236666B" discloses a wall structure and construction method for a house building. A first connecting plate is fixedly connected to the concrete wall along its height direction. Several second connecting plates for fixed connection with building blocks are vertically arranged on the first connecting plate. After the building blocks are placed in the accommodation space, they are fixed to the second connecting plates by nails. The building blocks are connected to the first connecting plates through the second connecting plates to realize the connection between the concrete wall and the masonry wall.

[0004] However, in this patent, the first connecting plate is a track-type structure and is fixed on the concrete wall, and the second connecting plate is slidably installed in the track. The front end of each building block abuts against the outer side of the first connecting plate, so that there is a gap between the masonry wall and the concrete wall, so that a continuous force interface cannot be formed between the masonry wall and the concrete wall. Under the action of external force, the connection part is likely to become a stress concentration area, causing cracks to extend along the gap to the masonry or concrete wall, accelerating structural damage, further weakening the connection strength, and failing to ensure the stability of the connection between the masonry wall and the concrete wall.

[0005] Based on this, it is necessary to study a building wall structure and construction method. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a wall structure and construction method for a building, which effectively solves the problems of easy cracking of mortar at the connection between existing concrete walls and masonry walls, insufficient structural integrity, and stability risks during long-term use.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a wall structure of a building, comprising a precast concrete wall and a masonry wall, wherein the masonry wall is formed by stacking a plurality of blocks, and the masonry wall and the concrete wall are fixedly connected together by a positioning and locking assembly, wherein the positioning and locking assembly comprises a connector, a positioning plate and a vertical rod, a vertical groove is provided on the concrete wall, a base is adapted to be installed in the vertical groove, the positioning plate is fixed in the base along a vertical interval, and a positioning hole is provided on the positioning plate; the connector is fixed on the block, and the inner end of the connector extends to the base and is located between two adjacent positioning plates; a perforation is provided on the connecting piece, and when the building block is against the concrete wall, the limiting hole and the positioning hole are coaxial; the vertical rod is sleeved in the positioning hole and the limiting hole to connect the building block and the adjacent positioning plate together; and the upper and lower ends of the vertical rod are respectively provided with a threaded head and a threaded segment, and the threaded segment on the vertical rod can be correspondingly threadedly connected to the adjacent threaded head, so that the adjacent two vertical rods are correspondingly threadedly connected together; the masonry wall formed by stacking multiple building blocks can block the opening of the vertical groove to form a casting space.

[0008] Furthermore, the connecting member includes a U-shaped clamp and a limiting plate, the U-shaped clamp is fixed to the building block by nails, the limiting plate is fixed to the outer wall of the U-shaped clamp, and the limiting plate is provided with a limiting hole; when the building block is against the concrete wall, the limiting plate on the connecting member extends into the vertical groove, and the limiting hole on the limiting plate is coaxial with the positioning hole on the positioning plate.

[0009] Furthermore, a strip-shaped groove is provided on the top of the U-shaped clip, and a protrusion is provided on the bottom thereof. The protrusion on one U-shaped clip can be adapted to be clamped in the groove on the other U-shaped clip.

[0010] Furthermore, concrete slurry is poured in the pouring space.

[0011] Furthermore, each building block is connected to a corresponding vertical rod, and the vertical rod is inserted into the limiting hole of the connecting piece and the two adjacent positioning plates; the upper and lower adjacent vertical rods are connected correspondingly through threaded heads.

[0012] Furthermore, the cross-section of the vertical groove is U-shaped or convex-shaped.

[0013] Furthermore, a guide groove is provided on the positioning plate, and the guide groove has a G-shaped structure. The inner end of the guide groove is connected to the positioning hole, and the guide grooves on the upper and lower adjacent positioning plates are symmetrically arranged.

[0014] Furthermore, the positioning plate includes a center plate and a connecting rod, one end of the connecting rod is welded and fixed to the side wall of the center plate, and the other end is welded to the base, and a positioning hole is opened on the center plate.

[0015] A construction method for a wall structure of a building comprises the following steps: Step 1: When pouring concrete walls, reserve vertical grooves in advance, embed the bases in the grooves according to the designed spacing, and weld positioning plates evenly on the bases; Step 2: Install the connector clamp on the block, and stack the blocks layer by layer in front of the vertical slot opening, so that the protrusions on the connector fit into the grooves and the blocks are in close contact with the concrete wall. At this time, the limit plate of the connector is inserted into the vertical slot and aligned with the hole of the positioning plate; Step 3: After the position of the first layer of blocks is determined, insert the vertical rod with a threaded head from top to bottom, passing through the positioning hole and the limit hole; then lay mortar on the top of the first layer of blocks, so that the top surface of the laid mortar is flush with the U-shaped clamp clamped on the block; Step 4: Install the second layer of blocks according to steps 2 and 3 above, and connect the upper and lower vertical rods together through the threaded heads; Step 5: Following steps 2-4 above, stack the blocks layer by layer from bottom to top until the top of the concrete wall is reached.

During the precast concrete wall production stage, a U-shaped vertical groove is reserved according to the design when supporting the formwork, and the base is fixed to the inner wall of the vertical groove by pre-embedded welding or bolts. During construction, the base is embedded in the formwork as an embedded part and welded and fixed to the steel frame of the concrete wall to ensure that it forms an integral part with the wall after pouring.

[0018] In addition, the precast concrete wall in the present invention has a precisely embedded base and positioning plate in the factory to ensure the structural size and positioning accuracy of the vertical groove, reducing the on-site adjustment process; during masonry construction, the concave and convex groove design of the U-shaped clamp connector can realize the rapid positioning of the block stacking; in addition, the design of the connection component embedded in the casting space avoids the need for secondary processing of exposed iron parts. After the wall is formed, the appearance is smooth and beautiful, while reducing the dependence of traditional wet operations on the construction environment, significantly improving construction efficiency, and having strong practicality.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This embodiment aims to provide a wall structure for a building, which is mainly used for the stable connection between the precast concrete main wall and the masonry wall in the building. The traditional method is to embed steel bars or fix them with L-shaped iron sheets by nailing, and then fill mortar between adjacent blocks, which easily causes the mortar at the wall connection to crack, resulting in a decrease in the strength of the connection. In addition, the existing technology uses the method of installing tracks outside the main wall to connect, which will cause a gap between the two walls, making it impossible to form a continuous force interface, and easily making the connection part a stress concentration area, making it difficult to ensure the coordinated force between the walls, and reducing the stability of the structure. Therefore, this embodiment provides a wall structure for a building, which realizes the precise positioning, rigid connection and integrity enhancement of the concrete wall and the masonry wall by combining the positioning and locking components with the casting space, avoiding the influence of exposed connectors on the wall appearance, and at the same time forming an "embedded" bond to effectively improve the shear strength.

[0022] like Figure 1-4 As shown, the present embodiment provides a building wall structure, comprising a precast concrete wall 1 and a masonry wall, wherein the masonry wall is formed by stacking a plurality of blocks 2, and the masonry wall and the concrete wall 1 are fixedly connected together by a positioning and locking assembly. Figure 2 As shown, the positioning and locking assembly includes a connecting piece 4, a positioning plate 5 and a vertical rod 6. In this embodiment, the main wall is a precast concrete wall 1. When making the main wall, the vertical groove 3 structure is first reserved according to the design drawing during formwork casting, and then the base 8 is fitted and installed on the inner wall of the vertical groove 3. In this embodiment, the vertical groove 3 structure is a U-shaped structure. The masonry wall is constructed in front of the opening of the vertical groove 3 of the concrete wall 1. After the masonry wall is stacked and formed, the opening of the vertical groove 3 can be blocked to form a casting space 9. Finally, concrete slurry is poured in the casting space 9 to complete the stable connection of the two walls.

[0023] In a specific embodiment, during the production stage of the precast concrete wall 1, a U-shaped vertical groove 3 is reserved according to the design when the formwork is supported, and the base 8 is fixed to the inner wall of the vertical groove 3 by pre-embedded welding or bolts. During construction, the base 8 is embedded in the formwork as a pre-embedded part and welded and fixed to the steel frame of the concrete wall 1 to ensure that it forms an integral part with the wall after pouring. After the concrete is cured, the formwork is removed to form a precast wall with a vertical groove 3 and a fixed base 8. Positioning plates 5 with positioning holes 13 are welded vertically at intervals in the base 8 to serve as anchor points for subsequent connectors 4. The connector 4 is fixed to the block 2, and the inner end of the connector 4 extends into the base 8 and is located between two adjacent positioning plates 5. Furthermore, in actual application, the connector 4 can be a flat plate structure, one end of which is fixed to the block 2 by nailing, and the other end extends into the pouring space 9 for connection with the positioning plate 5.

[0024] The connecting member 4 can also be Figure 3The structure shown in the figure is specifically that in this embodiment, the connecting member 4 includes a U-shaped clamp 41 and a limiting plate 42, wherein the U-shaped frame is fixed to one end of the block 2 by nailing, and the limiting plate 42 is fixed to the side wall of the U-shaped frame and is integrally formed with the U-shaped frame. The limiting plate 42 is provided with a limiting hole 45. When the block 2 is against the concrete wall 1, the limiting plate 42 of the connecting member 4 fixed on the block 2 extends into the vertical groove 3, and the limiting hole 45 on the limiting plate 42 is coaxial with the positioning hole 13 of the positioning plate 5 in the vertical groove 3. Further, as Figure 3 As shown, a strip groove 43 is provided on the top of the U-shaped clip 41, and a protrusion 44 is provided on the bottom. When two adjacent U-shaped clips 41 are stacked for masonry construction, the protrusion 44 on one U-shaped clip 41 can be adapted to be snapped into the groove 43 on the other U-shaped clip 41, thereby ensuring the verticality of the upper and lower adjacent building blocks 2 during assembly, providing a positioning function for the assembly of the building blocks 2.

[0025] like Figure 2 and 4 As shown, the vertical rod 6 is adapted to be mounted in the positioning hole 13 and the through-hole to connect the building block 2 and the adjacent positioning plate 5 together. In this embodiment, threaded sections are respectively provided at the upper and lower ends of the vertical rod 6, and a threaded head 7 is screwed on the upper threaded section. With such a setting, during construction, the vertical rod 6 with the threaded head 7 can be placed between the two adjacent positioning plates 5, and then the vertical rod 6 can be moved downward to the lower layer so that the vertical rod 6 is passed through the two adjacent positioning plates 5 and the connecting piece 4, and the threaded head 7 is installed on the top of the upper positioning plate 5, so that the upper vertical rod 6 can be threadedly connected with the threaded section on the upper vertical rod 6 during construction, so that each building block 2 corresponds to a section of vertical rod 6 from top to bottom, and the upper and lower adjacent vertical rods 6 are connected by the threaded head 7, thereby ensuring the stability of the connection between the positioning plate 5 on the concrete wall 1 and the connecting piece 4 on the building block 2.

[0026] After multiple blocks 2 are stacked from bottom to top to form a masonry wall, they can block the opening of the vertical groove 3, thereby blocking the vertical groove 3 to form a casting space 9. Finally, concrete slurry is poured into the casting space 9. After it is formed, the positioning and locking assembly is buried in the casting space 9, and the masonry wall and the concrete wall 1 are tightly connected together, which can not only ensure the beauty and smoothness of the connection between the walls, but also ensure the stability of the connection.

[0027] Based on the above-mentioned building wall structure, this embodiment further provides a construction method for a building wall, which specifically includes the following steps: Step 1: When pouring concrete walls, reserve vertical grooves in advance, embed the bases in the grooves according to the designed spacing, and weld positioning plates evenly on the bases; Step 2: Install the connector clamp on the block, and stack the blocks layer by layer in front of the vertical slot opening, so that the protrusions on the connector fit into the grooves and the blocks are in close contact with the concrete wall. At this time, the limit plate of the connector is inserted into the vertical slot and aligned with the hole of the positioning plate; Step 3: After the position of the first layer of blocks is determined, insert the vertical rod with a threaded head from top to bottom, passing through the positioning hole and the limit hole; then lay mortar on the top of the first layer of blocks, so that the top surface of the laid mortar is flush with the U-shaped clamp clamped on the block; Step 4: Install the second layer of blocks according to steps 2 and 3 above, and connect the upper and lower vertical rods together through the threaded heads; Step 5: Following steps 2-4 above, stack the blocks layer by layer from bottom to top until the top of the concrete wall is reached. After the construction of the masonry wall is completed, the masonry wall seals the vertical groove opening to form a closed pouring space; Step 6: Pour concrete slurry into the pouring space from the top of the vertical groove to fill the gap between the connector and the positioning plate. After the concrete hardens, the two walls form an integral load-bearing structure and the connection is completed.

[0028] The wall structure and construction method of a house building provided by the present invention realize the coordinated force of the two walls by combining the positioning locking component with the casting space 9. The vertical rods pass through the positioning holes and the limit holes, and the upper and lower sections are connected by threads to form a continuous force skeleton. After the masonry blocks the vertical groove opening, a closed space is formed, and concrete is poured to form an embedded bond to enhance the shear strength. By combining modular prefabrication with on-site assembly, it takes into account both efficiency and structural performance, is suitable for the needs of modern building industrialization, and is highly practical.

[0029] Example 2: Based on Example 1, this example further illustrates the structure of the vertical groove 3 in the precast concrete wall 1.

[0030] The structure of the vertical groove 3 can also be as follows Figure 5 As shown, the vertical groove 3 has an inverted U-shaped cross-section, with a base 8 of the same shape fitted to the inner wall of the vertical groove 3. The vertical groove 3 opens toward the wall structure of the block 2. This arrangement creates an inwardly constricted opening at the outer end of the vertical groove 3, further enhancing the stability of the connection compared to the U-shaped cross-section of the vertical groove 3 in Example 1.

[0031] Example 3: Based on Example 2, this example provides another structure of the positioning plate 5.

[0032] like Figure 6As shown, the positioning plate 5 includes a center plate 15 and a connecting rod 16. One end of the connecting rod 16 is welded to the side wall of the center plate 15, and the other end is welded to the base 8. A positioning hole 13 is opened on the center plate 15. After the building block 2 is fitted and installed on the front side of the concrete wall 1, the positioning hole 13 is coaxial with the limiting hole 45 of the connecting member 4, making it easy to lock and connect the two through the vertical rod 6. From the perspective of mechanical performance, the structural arrangement of the positioning plate of this embodiment is such that the connecting rod 16 welds the center plate 15 and the base 8 into a rigid triangular support system, which can effectively disperse the shear stress and bending moment at the connection point, avoiding the risk of local deformation caused by single-point force in the traditional integral positioning plate 5.

[0033] Example 4: Based on Example 2, this example provides another structure of the positioning plate 5.

[0034] like Figure 7 As shown, in order to facilitate the assembly of the vertical rod 6, a guide groove 14 is provided on the positioning plate 5 in this embodiment. The guide groove 14 is a G-shaped structure, and the inner end of the guide groove 14 is connected to the positioning hole 13. The guide grooves 14 on the upper and lower adjacent positioning plates 5 are symmetrically arranged, and the end positioning holes 13 are coaxial. With this arrangement, the vertical rod 6 can be directly moved into the guide groove 14 through the opening of the guide groove 14, and the position of the vertical rod 6 can be adjusted up and down in the guide groove 14. After the connecting member 4 extends into the vertical groove 3, the vertical rod 6 is moved downward and passed through the limiting hole 45 of the connecting member 4. After the construction of the masonry wall is completed, the vertical rods 6 of each section are coaxial and connect the two walls together.

[0035] In this embodiment, the G-shaped guide groove 14, with its symmetrical layout, provides the vertical rod 6 with multiple degrees of freedom for adjustment. During construction, the vertical rod 6 can slide horizontally along the opening of the guide groove 14 and move up and down. The vertical rod 6's sliding path is constrained by the groove body, allowing for rapid pre-positioning during the initial installation phase and fine-tuning of the vertical rod 6's position after the blocks 2 are stacked, ensuring its precise alignment with the limiting holes 45 of the connector 4. At the same time, the design of the inner end of the guide groove 14 connecting to the positioning hole 13 forms a continuous channel from temporary positioning to final locking, avoiding the stringent requirement of traditional vertical plug-in to fully align the holes, significantly reducing installation difficulty. Furthermore, construction workers can insert the vertical rod 6 horizontally into the guide groove 14 without strictly aligning the holes, significantly reducing manual calibration time. The open design of the guide groove 14 also facilitates real-time observation of the alignment between the vertical rod 6 and the connector 4 during construction, allowing for timely correction of deviations, avoiding rework problems caused by visual blind spots in traditional closed-cell structures and improving construction flexibility.

[0036] Example 5: The similarities between this embodiment and Example 1 are not repeated here. The difference is that this embodiment provides another locking structure between the positioning plate 5 and the connecting member 4.

[0037] When assembling the vertical rod 6 in the above-mentioned embodiment 1, it is first moved in a horizontal push manner to the corresponding hole position in the middle of the positioning plate 5 of the target construction area, and then the vertical rod 6 is moved upward. After the limit plate 42 of the connecting member 4 is assembled between the positioning plates 5, the vertical rod 6 is moved downward so that the vertical rod 6 is passed through the positioning plate 5-connecting member 4-positioning plate 5, and then the upper and lower adjacent vertical rods 6 are connected and screwed together through the threaded heads 7. This construction method is likely to cause construction inconvenience and troublesome operation. Therefore, this embodiment provides another connection structure for locking the positioning plate 5 and the connecting member 4 together.

[0038] like Figure 8 As shown, the connection structure described in this embodiment includes a fixing sleeve 10, a screw 11 and a connecting sleeve 12, wherein the fixing sleeve 10 is installed in the limiting hole 45 of the connecting member 4, and the fixing sleeve 10 is threaded, and the upper and lower screws 11 are threadedly connected in the fixing sleeve 10. By screwing the upper and lower screws 11, they can respectively perform telescopic movements in the fixing sleeve 10; a connecting sleeve 12 is fixed in the positioning hole 13 of the positioning plate 5, and when the screw 11 in the fixing sleeve 10 extends outward, it can be respectively sleeved in the connecting sleeves 12 on the upper and lower sides, thereby connecting the positioning plate 5 and the connecting member 4 together, that is, connecting the concrete wall 1 and the masonry wall together.

[0039] Explanation of the working principle: The connection structure provided in this embodiment is used for locking the positioning plate and the connecting piece. Before the stacking construction of the blocks, the connecting sleeve is first fixedly mounted in the positioning hole, and the fixing sleeve is fixedly mounted in the limiting hole of the connecting piece to ensure that the connecting piece is mounted in the middle position of the fixing sleeve. Then the upper and lower sections of the screw are threadedly connected in the fixing sleeve to ensure that the distance between the top ends of the upper and lower screws is less than the distance between adjacent positioning plates. Therefore, during the construction of the blocks, it can be ensured that the connecting piece and the fixing sleeve can be located between adjacent positioning plates to avoid the screw being too long and affecting the construction. After the adjacent connecting pieces are matched with each other, the two screws in the fixing sleeve are screwed to move them toward each other and fixed to the connecting sleeves at the upper and lower ends respectively. The above-mentioned method is used to install each layer of blocks in turn from bottom to top. Finally, grouting can be performed in the casting space.

[0040] In this embodiment, the threads of the screw and the fixing sleeve form an adjustable rigid connection node. Tightening the screw to achieve telescopic locking not only precisely controls the spacing between the connector and the positioning plate, but also avoids the hole misalignment problem associated with traditional vertical rod installation. The design of the upper and lower screws embedded in the connecting sleeve converts shear force into thread engagement force. Combined with the embedded constraints of the concrete after pouring, this creates a multi-level force transmission path, significantly improving both shear and tensile strength. Furthermore, during construction, there's no need to repeatedly adjust the vertical rod position; simply twisting the screw allows for precise alignment and locking of the upper and lower connecting sleeves, reducing operational complexity.

[0041] The embodiments of the present invention described above do not constitute limitations on the scope of protection of the present invention. The basic concept of the present invention is that, through the coordinated design of the positioning and locking components and the casting space, the connection between the precast concrete wall and the masonry wall forms a dual reinforcement mechanism of rigid skeleton and embedded bonding, effectively enhancing the stability of the connection between the two walls, forming a continuous and homogeneous stress interface between the two walls, avoiding stress concentration, and improving the practicality of construction. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims.
