Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled combined lateral force resisting component for low-rise houses. Background Art

[0002] As a highly efficient construction method, the layered prefabricated braced steel frame system has been widely adopted in low-rise buildings, particularly in the construction of one- to three-story villas. This construction method features continuous beams and disconnected columns, and utilizes fully bolted connections to enable rapid assembly of the structure, significantly improving construction efficiency and architectural flexibility. However, in practical application, existing inter-column bracing designs still face challenges, which, to a certain extent, limit the system's scope of application and development potential.

[0003] In the existing technology, the forms of inter-column supports are various, including "basket bolts + round steel", "cylindrical sleeves + round steel" and "hexagonal prism sleeves + round steel + flat steel". Although these designs are well adapted to light steel frame enclosure walls, they are not very suitable for more common enclosure walls such as masonry or ALC strips. Specifically, there is often a spatial conflict between the inter-column supports and masonry or ALC strips, resulting in the need for extra time and effort to adjust the position or cut the wall materials during construction. This not only increases the difficulty of construction, but also reduces construction efficiency, prolongs the construction period and increases costs. Especially in low-rise buildings such as villas, due to the large number of windows on the front and back facades, the available space is very limited. This spatial conflict is even more obvious, which limits the lateral resistance of the inter-column supports, making it difficult to achieve the ideal lateral stiffness, and further weakening their effectiveness in wind and earthquake resistance.

[0004] Secondly, for lateral force-resisting structures, the existing solution is typically to use precast reinforced concrete components. Especially for low-rise buildings with one to three floors, these components are often designed as full-height structures and placed in the building's corners to provide the necessary horizontal resistance. However, this design presents new challenges. First, full-height precast reinforced concrete components are large and weigh up to four to five tons, making them difficult to transport and requiring heavy machinery for on-site installation. This presents a significant obstacle in mountainous areas with inaccessible transportation or complex terrain, severely limiting their widespread use. Second, when low-rise buildings feature terraces, full-height precast components become inappropriate, as they require vertical alignment to ensure continuous vertical force transmission, and exposure to the open air disrupts this continuity. Therefore, finding more flexible, lightweight, and easy-to-install lateral force-resisting structures while ensuring structural safety has become a pressing technical challenge. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide an assembled combined lateral force resisting member for low-rise houses, so as to solve the problems in the prior art, especially in low-rise buildings, such as the conflict between the inter-column support and the front and rear facade window design, the large size of the existing full-height lateral force resisting members, the difficulty in transportation, and the inability to coordinate with the terrace structure in the low-rise buildings.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A prefabricated combined lateral force resisting member for low-rise houses comprises a plurality of steel pipe columns arranged in a vertical direction, wherein the length directions of two adjacent steel pipe columns are parallel to each other; a connecting member is provided between the two adjacent steel pipe columns, and the two sides of the connecting member are respectively fixedly connected to the side walls opposite to the two adjacent steel pipe columns, so that the plurality of steel pipe columns are distributed in an L-shape or a straight line; an end plate is provided at each end of the steel pipe column, wherein the end plate is fixedly connected to the steel pipe column, and the lateral force resisting member is fixedly connected to the steel beam via the end plate; the lateral force resisting member is suitable for low-rise houses with 1 to 3 floors.

[0008] Preferably, the connecting member is a plurality of connecting plates, which are arranged along the length direction of the steel pipe column and close to the side wall of the two adjacent steel pipe columns. The opposite side edges of the connecting plate are respectively fixedly connected to the opposite side walls of the two adjacent steel pipe columns, and one side surface of the connecting plate is flush with the outer side surfaces of the two adjacent steel pipe columns; a plurality of reinforcing members are also provided between the connecting plate and the steel pipe column, and the reinforcing members are respectively fixedly connected to the connecting plate and the steel pipe column.

[0009] Preferably, the reinforcing member includes at least two connecting rods, which are located between two adjacent steel pipe columns and on opposite sides of the connecting plate away from the two ends of the steel pipe columns; the two ends of the connecting rod are respectively fixedly connected to the opposite side walls of the two adjacent steel pipe columns, and one side outer wall of the connecting rod is fixedly connected to a side edge of the connecting plate away from the two ends of the steel pipe columns, so that the outer side surface of the connecting rod is flush with one side surface of the connecting plate and the outer side surfaces of the two adjacent steel pipe columns.

[0010] Preferably, the connecting member includes a plurality of transverse steel bars and vertical steel bars, and the transverse steel bars and vertical steel bars are laid between opposite sides of two adjacent steel pipe columns. The transverse steel bars are arranged in a horizontal direction, and their two ends are fixedly connected to the surfaces of opposite sides of the two adjacent steel pipe columns; the vertical steel bars are arranged in a vertical direction and fixedly connected to the transverse steel bars; concrete is poured between the two adjacent steel pipe columns so that the concrete covers the transverse steel bars and the vertical steel bars.

[0011] Preferably, both ends of the transverse reinforcement are bent and extended along the length direction of the steel pipe column to form connecting ends; and the transverse reinforcement is fixedly connected to two adjacent steel pipe columns via the connecting ends.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The utility model improves the lateral anti-components and adopts steel components to make connecting plates and connecting rods, so as to make the lateral anti-components lighter and avoid full-height design, so that the lateral anti-components are suitable for low-rise houses with terrace structures. Moreover, compared with prefabricated reinforced concrete components, the manufacturing process is simpler, and the concrete curing time is saved, the production cycle is greatly reduced, and the overall weight is only 0.2 to 0.3 tons, which is much lighter than the traditional prefabricated reinforced concrete components weighing 4 to 5 tons. At the same time, there is no need for full-height production, the components are shorter, and transportation and installation are more convenient.

[0014] 2. This utility model also makes targeted adjustments to the lateral force-resisting members. To avoid building walls between cross supports and address the collision problem between existing support structures and masonry, the lateral force-resisting members use steel pipe columns at both ends to bear vertical loads, while the middle section uses concrete and transverse reinforcement to bear horizontal loads. This gives the lateral force-resisting members high overall rigidity, allowing them to meet lateral force requirements by simply placing them at building corners. Furthermore, the lateral force-resisting members are also suitable for situations where the lateral force-resisting members are discontinuous, meeting the structural design requirements of low-rise buildings with terraces. Furthermore, this steel-concrete composite lateral force-resisting member weighs approximately 1.1 tons at its maximum, a weight reduction of over 70% compared to the 4-5 tons of traditional precast reinforced concrete members.

[0015] 3. The anti-side member of the utility model can be made into a standardized component, which is convenient for standardized production in the factory, so that it can meet the needs of more building types and has a good application prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the present invention are within the scope of protection of the present invention.

[0024] The utility model provides an assembled combined lateral force resisting member for low-rise houses, such as Figures 1 to 6 As shown, it includes multiple steel pipe columns 1 arranged in the vertical direction, and the length directions of two adjacent steel pipe columns are parallel to each other; a connecting member is provided between the two adjacent steel pipe columns, and the two sides of the connecting member are respectively fixedly connected to the side walls opposite to the two adjacent steel pipe columns, so that the multiple steel pipe columns are distributed in an L shape or a straight line; an end plate 6 is provided at both ends of the steel pipe column, and the end plate is fixedly connected to the steel pipe column, and the lateral force resisting member is fixedly connected to the steel beam through the end plate; the lateral force resisting member is suitable for low-rise houses with 1 to 3 floors.

[0025] In some embodiments of the present invention, the connecting member is a plurality of connecting plates 2, which are arranged along the length direction of the steel pipe column and close to the side wall of the two adjacent steel pipe columns. The two opposite sides of the connecting plate are fixedly connected to the opposite side walls of the two adjacent steel pipe columns, and one side surface of the connecting plate is flush with the outer surface of the two adjacent steel pipe columns. A plurality of reinforcing members are also provided between the connecting plate and the steel pipe column, and the reinforcing members are fixedly connected to the connecting plate and the steel pipe column respectively. When the multiple steel pipe columns are distributed in an L shape, such as Figure 3 As shown in the figure, the connecting plate is located on the outside of two adjacent steel pipe columns, so that after multiple steel pipe columns are connected by the connecting plate, the outer wall of the steel pipe column is flush with the outer wall of the connecting plate and forms an L shape. This L-shape has better overall lateral resistance. For low-rise houses with 1 to 3 floors without terraces, this L-shaped lateral force resisting member only needs to be arranged at the corner of the house to meet the lateral resistance requirements, which also makes the lateral force resisting member more standardized. When multiple steel pipe columns are distributed in a straight line, such as Figures 1 and 2As shown, the other two sides of the connecting plate that are not connected to the steel pipe column have a certain distance between them and the two ends of the steel pipe column, that is, the other two sides of the connecting plate that are not connected to the steel pipe column do not extend to the two ends of the steel pipe column, so that after the lateral force resisting member is connected to the steel beam, a reserved opening 7 is formed between the connecting plate and the steel beam. The purpose of setting this opening is to prevent the middle connecting plate from bearing vertical loads, but only bear horizontal forces, while facilitating the passage of the steel bars of the floor slab, and leaving enough operating space for the lateral force resisting member to be bolted to the steel beam. When a 1 to 3-story low-rise house has a terrace design, a straight-line lateral force resisting member can be used to ensure the lateral resistance effect while meeting the terrace design needs. A plurality of reinforcing members are also provided between the connecting plate and the steel pipe column, and the reinforcing members are fixedly connected to the connecting plate and the steel pipe column, respectively. As shown Figures 1-3 As shown, the reinforcing member includes at least two connecting rods 3, which are located between two adjacent steel pipe columns and on opposite sides of the connecting plate away from the ends of the steel pipe columns. The ends of the connecting rods are respectively fixedly connected to the opposite side walls of the two adjacent steel pipe columns, and the outer wall of one side of the connecting rod is also fixedly connected to the side edge of the connecting plate away from the ends of the steel pipe columns. In this embodiment, the lateral force-resisting member does not need to be made full height, which makes it suitable for houses with terrace structures. Moreover, the lateral force-resisting member is entirely made of lightweight steel products. The connecting rods and connecting plates between the steel pipe columns can be connected by welding, and can be used directly without pouring concrete. Compared with precast reinforced concrete components, the manufacturing process is simple, and the concrete curing time is eliminated, greatly reducing the production cycle. In this embodiment, the weight of the lateral force-resisting member is greatly reduced to only 0.2-0.3 tons, making it more convenient to transport and install. At the same time, in low-rise buildings such as villas, this embodiment can meet the demand for more windows on the front and back facades, while achieving lateral stiffness and enhancing its wind and earthquake resistance.

[0026] In some embodiments of the present invention, Figures 4-6As shown, the connecting member includes multiple transverse steel bars 4 and vertical steel bars 5. The transverse and vertical steel bars are laid between opposite sides of two adjacent steel pipe columns. The transverse steel bars are arranged horizontally, with their ends fixedly connected to the opposite surfaces of the two adjacent steel pipe columns. The vertical steel bars are arranged vertically and fixedly connected to the transverse steel bars. Concrete is poured between the two adjacent steel pipe columns, so that the concrete covers the transverse and vertical steel bars. The ends of the transverse steel bars are bent and extended along the length of the steel pipe columns to form connecting ends 8. The transverse steel bars are fixedly connected to the two adjacent steel pipe columns via connecting ends 8. This embodiment can be used alone or in conjunction with the above-mentioned connecting rods, or in conjunction with connecting plates, or in conjunction with connecting plates and connecting rods. The lateral force resisting member can be formed into a straight or L-shaped shape. The L-shaped shape is also suitable for low-rise buildings with 1 to 3 floors and no terraces. It can be installed in the corner of the house to achieve a good lateral force resisting effect. The straight shape is also suitable for low-rise buildings with 1 to 3 floors and terraces, ensuring continuous vertical force transmission. By connecting the through beam with high-strength bolts to form an anti-lateral structure, the anti-lateral force member has both anti-lateral and enclosure functions, avoiding the construction of walls in the middle of the cross support, thus solving the problem of collision between the existing support form and the masonry. At the same time, in this embodiment, the side of the connecting plate between the two adjacent steel pipe columns is not flush with the end of the steel pipe column, so that after the anti-lateral force member is connected to the steel beam, a reserved opening 7 is formed between the connecting plate and the steel beam. The purpose of setting this opening is to prevent the middle connecting plate from bearing vertical loads, but only bear horizontal forces, while facilitating the passage of the steel bars of the floor slab, and leaving enough operating space for the anti-lateral force member to be bolted to the steel beam.

[0027] The present invention is not limited to the above-mentioned embodiments. Any structure that is the same as or similar to the above-mentioned embodiments of the present invention is within the protection scope of the present invention.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
