Description

Technical Field

[0001] This utility model relates to the field of building structures, and in particular to a prefabricated assembled bolt-U-shaped steel-block dry-operation plaster-free composite wall structure. Background Technology

[0002] In traditional masonry structures, masonry walls are primarily constructed by bonding block materials with mortar. Diverse masonry methods and staggered joint techniques are used to build the walls, avoiding vertical continuous joints and effectively distributing stress, thus enhancing the wall's integrity and stability. The block materials, as the main load-bearing components, directly determine the wall's compressive strength; while the mortar acts as a binder, bonding the blocks into a unified whole to share the load. Due to its wide availability of materials, low cost, and mature construction techniques, masonry walls are widely used in residential buildings, small public buildings, and industrial buildings.

[0003] However, while this traditional masonry method has a long history and mature technology, it suffers from low construction efficiency, high costs, and stringent requirements for the technical skills of construction workers—problems that are becoming increasingly prominent in modern construction. Furthermore, this wet construction method generates a large amount of dust and waste, causing significant environmental pollution. Simultaneously, due to the unevenness of the mortar layer, the bonding strength of the masonry structure is relatively low, making the wall prone to cracking or even failure under heavy loads, thus affecting the structure's safety and durability. In summary, traditional masonry wall solutions have the following limitations:

[0004] 1. Low construction efficiency: Traditional masonry wall construction relies on on-site wet work, including mortar mixing and laying. This construction method is not only cumbersome, but the construction speed is also limited by manual operation and weather conditions, making it difficult to achieve rapid construction and strict control over the project schedule. For example, in the rainy season or under low temperature conditions, the mortar setting speed slows down, causing the construction progress to stagnate and affecting the overall project schedule.

[0005] 2. Significant Environmental Impact: Wet construction processes generate large amounts of dust, wastewater, and construction waste. These pollutants not only severely impact the construction site and surrounding environment but may also harm the respiratory health of construction workers through dust dispersion. Furthermore, the waste generated during construction is often difficult to effectively recycle and reuse, increasing the burden of construction waste disposal and contradicting current green building principles and sustainable development goals.

[0006] 3. Insufficient Structural Performance: During the construction of traditional masonry walls, the unevenness of the mortar layer often leads to voids in the mortar joints or inconsistent mortar layer thickness, thus weakening the bond between the bricks and the mortar, and consequently affecting the integrity and seismic performance of the masonry wall. Furthermore, traditional masonry walls have poor crack resistance and are prone to cracking due to temperature changes or uneven foundation settlement. This not only affects the aesthetics of the structure but also severely reduces its durability and service life.

[0007] 4. Difficulty in quality control: The quality of mortar and the masonry process directly affect the final quality of the wall. However, in on-site construction, it is difficult to accurately control the mortar mix ratio, the uniformity of mixing, and the standardization of the masonry process, which affects the overall quality of the building.

[0008] 5. High labor intensity: Traditional masonry wall construction mainly relies on manual operation, which is labor-intensive and requires a large workforce.

[0009] 6. Significant material waste: Due to the difficulty in precisely controlling the amount of mortar and blocks used during construction, material waste frequently occurs on-site. For example, on-site cutting of blocks generates a large number of fragments, further increasing the material loss rate.

[0010] Therefore, an innovative wall structure solution is needed that can optimize the construction process, improve construction efficiency, and further enhance the overall strength and durability of the wall. Summary of the Invention

[0011] In view of this, the purpose of this utility model is to propose a prefabricated assembled bolt-U-shaped steel-block dry-operation plaster-free combined wall structure that is simple in structure, reliable in implementation, and can be dry-operated without plastering.

[0012] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0013] A prefabricated, assembled bolt-U-shaped steel-block dry-work, plaster-free composite wall structure includes a main wall structure. The main wall structure includes a first cover plate, multiple first anchor bolts, and multiple main wall components stacked vertically. Each main wall component includes a first U-shaped steel and a first block. The first block is disposed within the U-shaped structure of the first U-shaped steel. The lower end face of the first U-shaped steel is in contact with the upper end face of the first U-shaped steel of the main wall component below it. The first cover plate is fixedly connected to the upper end face of the uppermost main wall component. Multiple first anchor bolts pass through the lowermost main wall component and fix it to the installation ground.

[0014] As one possible implementation, the main wall assembly further includes multiple first bolts. The bottom of the U-shaped structure of the first U-shaped steel of the main wall assembly has multiple pairs of first mounting holes spaced along its length. The first bolts of the main wall assembly pass downwards through the first mounting holes of the first U-shaped steel of the upper main wall assembly, through the first block of the main wall assembly, and are locked in place with the first mounting holes of the first U-shaped steel of the main wall assembly, thus fixing the adjacent main wall assemblies relatively. The first cover plate has multiple second mounting holes along its length, covering the uppermost main wall assembly. The first bolt of the uppermost main wall assembly passes downwards through the second mounting holes of the first cover plate, through the first block of the uppermost main wall assembly, and is threadedly locked in place with the first mounting holes on the corresponding first U-shaped steel of the uppermost main wall assembly.

[0016] As one possible implementation, further, the number of the first blocks in this solution is multiple, and the multiple first blocks are arranged in the U-shaped structure of the first U-shaped steel, wherein the sides of adjacent first blocks are attached to form a joint, and the joints formed by the first blocks of adjacent main wall components are staggered in the vertical direction.

[0017] As a preferred implementation option, the combined wall structure of this solution preferably includes a corner wall structure disposed on one side of the main wall structure; specifically, the corner wall structure of this solution includes a second cover plate, a second anchor bolt, and multiple corner wall components stacked sequentially in the vertical direction. The corner wall component includes a second U-shaped steel and a second block. The second U-shaped steel has an L-shaped profile, and the second block is disposed within the U-shaped structure of the second U-shaped steel. The lower end face of the second U-shaped steel is in contact with the upper end face of the second U-shaped steel of the corner wall component below it. The second cover plate is fixedly connected to the upper end face of the corner wall component located at the uppermost end. At least one of the second anchor bolts passes through the corner wall component located at the lowermost end and fixes it to the installation ground.

[0018] As a preferred implementation option, the corner wall assembly of this solution further includes at least one second bolt. The bottom of the U-shaped structure of the second U-shaped steel of the corner wall assembly is provided with at least a pair of third mounting holes spaced apart. The second bolt of the corner wall assembly passes downward through the third mounting hole of the second U-shaped steel of the upper corner wall assembly, through the second block of the corner wall assembly, and is locked in place with the third mounting hole of the second U-shaped steel of the corner wall assembly, thus fixing the adjacent corner wall assemblies relatively. The second cover plate is provided with at least one fourth mounting hole, which covers the uppermost corner wall assembly. The second bolt of the uppermost corner wall assembly passes downward through the fourth mounting hole of the second cover plate, through the second block of the uppermost corner wall assembly, and is threadedly locked in place with the third mounting hole on the corresponding second U-shaped steel of the uppermost corner wall assembly. At least one second anchor bolt passes downward through the third mounting hole on the second U-shaped steel of the lowermost corner wall assembly and is threaded into the installation ground, fixing the corner wall assembly to the installation ground.

[0019] As a preferred implementation option, the third mounting hole in this solution is preferably a threaded hole or a non-threaded through hole, and the fourth mounting hole is a non-threaded through hole; wherein, the third mounting holes on the second U-shaped steel of the bottommost corner wall component are all threaded holes; the multiple pairs of second mounting holes on the second U-shaped steel of the remaining corner wall components are combined into a pair of threaded holes and non-threaded through holes, wherein the second bolt of the corner wall component passes downward through the third mounting hole of the second U-shaped steel of the upper corner wall component (which is a non-threaded through hole) and locks into the third mounting hole of the second U-shaped steel of the corner wall component, thereby fixing the adjacent corner wall components relatively.

[0020] As a preferred implementation option, the number of the second blocks in this scheme is multiple, and the multiple second blocks are arranged in the U-shaped structure of the second U-shaped steel, wherein the sides of adjacent second blocks are attached to form a joint, and the joints formed by the second blocks of adjacent corner wall components are staggered in the vertical direction.

[0021] As a preferred implementation option, preferably, one side of the main wall structure in this solution is opposite to one side of the corner wall structure, forming a joint between them. In this case, a portion of the first block of the main wall structure extends horizontally beyond the U-shaped structure of the first U-shaped steel and crosses the joint to enter the U-shaped structure of the second U-shaped steel of the corner wall structure, and / or a portion of the second block of the corner wall structure extends horizontally beyond the U-shaped structure of the second U-shaped steel and crosses the joint to enter the U-shaped structure of the first U-shaped steel of the main wall structure.

[0022] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0023] 1. Improved construction efficiency: During the construction of the wall structure in this scheme, a completely dry construction process can be used to replace the traditional wet construction method, and bolt connections can replace traditional mortar bonding, thereby eliminating the tedious process of on-site mortar mixing.

[0024] 2. Reduced Environmental Pollution: Compared to traditional wet construction, the dry construction method in this wall structure scheme eliminates the use of large amounts of cement mortar, reducing water pollution and mud discharge at the construction site. Furthermore, the dry construction method utilizes prefabricated components and mechanized installation, avoiding on-site cutting and mixing processes, thus effectively reducing dust and waste generation during construction. This construction method not only improves construction efficiency and reduces labor costs but also significantly reduces negative environmental impacts, making it more environmentally friendly and aligning with the requirements of green building.

[0025] 3. Enhanced Structural Performance: This design employs a bolt-U-shaped steel-block prefabricated connection method for the wall structure, replacing the traditional method of bonding block materials with mortar, eliminating the need to wait for the concrete and mortar to cure. The wall's strength is immediately apparent upon completion. Furthermore, by completely eliminating the problem of mortar unevenness, the overall strength of the building is significantly improved.

[0026] 4. Easy Disassembly: This design uses a prefabricated construction method for the wall structure, replacing the traditional mortar design, making the disassembly and reassembly of the building much easier. Since no mortar is needed, there is no concern about mortar residue during dismantling, enabling efficient disassembly and rapid reassembly for reuse, greatly improving the building's flexibility and sustainability.

[0027] 5. High Usability: This design utilizes a large number of hollow blocks as the first and second building blocks in its wall structure. Due to the high usability of these hollow blocks, their internal cavities can be flexibly filled with various materials according to different building requirements. For example, to meet thermal insulation needs, rock wool, polystyrene foam, or other insulation materials can be filled; if wall strength needs to be increased, cement mortar or other reinforcing materials can be poured in.

[0028] In summary, this solution proposes an innovative wall structure technology that uses bolts, U-shaped steel, and masonry blocks to form a composite wall structure. This achieves dry construction without plastering. The core of this solution is that it can be constructed using dry methods, abandoning the traditional wet masonry method. Furthermore, the mechanical connection enables rapid assembly of the structure. Attached Figure Description

The second cover plate 21 is provided with at least one fourth mounting hole 211, which covers the uppermost corner wall assembly 23.

[0047] exist Figure 2 , Figure 4 , Figure 7 Based on what has been shown, further focus on combining Figure 8 As shown, as a preferred implementation option, preferably, the third mounting hole 2311 in this solution is a threaded hole 23111 or a non-threaded through hole 23112, and the fourth mounting hole 211 is a non-threaded through hole; wherein, the third mounting holes 2311 on the second U-shaped steel 231 of the lowermost corner wall component 23 are all threaded holes 23111; the multiple pairs of second mounting holes 2311 on the second U-shaped steel 231 of the remaining corner wall components 23 are threaded holes 23111 and non-threaded through holes 23111. The threaded through holes 23112 are combined into a pair.

[0048] In this embodiment, except for the bottom corner wall component 23, the second mounting holes 2311 on the second U-shaped steel 231 of the other corner wall components 23 are threaded holes and non-threaded through holes that are staggered to each other, so as to facilitate the installation of the second bolt 233; of course, this solution is not limited to this. As an example, the second mounting holes 2311 can all be threaded holes.

[0049] Regarding the implementation of the second block 232, as a preferred implementation option, it is preferred that the number of the second block 232 in this scheme is multiple, and the multiple second blocks 232 are arranged in the U-shaped structure of the second U-shaped steel 231, wherein the sides of adjacent second blocks 232 are attached to form a joint, and the joints formed by the second blocks 232 of adjacent corner wall components 23 are staggered in the vertical direction.

[0050] The corner wall structure 20 in this scheme is implemented using the aforementioned structural design.

Construction workers can assemble the components from bottom to top: first, the lowest corner wall component 23 is fixedly connected to the installation ground (installation holes for multiple second anchor bolts 22 can be pre-drilled in the ground); then, other corner wall components 23 are assembled layer by layer upwards, finally covering with the second cover plate 21. Similarly, the staggered assembly of the second blocks 232 improves the overall structural strength and stability of the wall.

In this case, a portion of the first block 132 of the main wall structure 10 extends horizontally beyond the U-shaped structure of the first U-shaped steel 131 and crosses the joint to enter the U-shaped structure of the second U-shaped steel 231 of the corner wall structure 20, and / or a portion of the second block 232 of the corner wall structure 20 extends horizontally beyond the U-shaped structure of the second U-shaped steel 231 and crosses the joint to enter the U-shaped structure of the first U-shaped steel 131 of the main wall structure 10. This solution employs an alternating arrangement of first block 132 and second block 232 at the transition between the main wall structure 10 and the corner wall structure 20. This improves the connection reliability between the main wall structure 10 and the corner wall structure 20 and reduces the risk of wall misalignment caused by vertical stress.
