Description

Technical Field

[0001] This application relates to the field of building technology, specifically to a modular, lightweight frame building structure. Background Technology

[0002] Based on rural revitalization, small- and medium-sized buildings, such as villas, have received significant attention. Choosing a structural type more suitable for rural villas has become a key focus. Rural villa construction differs significantly from large-scale urban construction in many aspects, including functional design, material selection and application, construction, and transportation. It has been proven that simply copying existing experience and technology cannot meet actual needs. Therefore, selecting a suitable building structure for rural villas is a concern not only for the client but also for the designer and manufacturer. Currently, the more mature or recognized mainstream types can be categorized as follows: 1. Concrete structures and types with concrete as the main structure; 2. Ordinary frame steel structures; 3. Light steel ribbed structures, also commonly referred to as light steel villas; 4. Modular integrated building types, etc.Concrete structures have proven to be cost-effective in urban construction, offering low cost, ideal comfort, and long lifespan. However, for rural villas, their small size and scale, lack of economies of scale, and relatively remote and scattered locations increase transportation difficulties. Furthermore, their high dependence on local industries significantly increases construction costs, and the long construction period makes them unsuitable for the practical requirements of this field. Secondly, ordinary frame steel structures offer short construction periods and meet requirements for safety, durability, and comfort. However, their steel consumption is relatively high compared to small rural villas, and the connection of their structural features with various new cladding materials presents technical challenges, leading to higher material and transportation costs, as well as higher labor intensity, making it difficult to reduce overall construction costs and resulting in a less marketable overall construction cost. Thirdly, light steel villas offer advantages such as lightweight structure, excellent earthquake resistance, high prefabricated material yield, low dependence on local industries, short construction periods, and relatively lower construction difficulty and labor intensity compared to the previous two types. The advantages of these structures, such as significantly reduced costs and convenient transportation, have gained widespread recognition worldwide. However, based on my country's cultural background and values, the structure is generally considered too light (its structural steel is typically 0.6mm thick, belonging to the ultra-thin plate series). Furthermore, issues such as vibration and low insulation in terms of comfort, as well as doubts about its durability and lifespan, have not been fully accepted. In addition, the complex assembly and construction processes and high professional requirements for installation further increase the difficulty of its application. Finally, there are modular integrated building structures, primarily container houses for rural villas. Their steel consumption falls between ordinary frame steel structures and light steel ribbed structures, and the structural materials are thin plates (also falling between ordinary frame steel structures and light steel ribbed structures). They have high integration and yield rates, and are the fastest to build compared to the former. On-site installation only requires hoisting or simple assembly, resulting in lower construction and transportation costs. However, this type is more suitable for campsite construction, lacking the aesthetic requirements of permanent buildings and villa designs, including exterior and interior layouts, to meet the diverse lifestyle needs of this field. The aforementioned issues pose significant challenges on both the demand and design / manufacturing sides. Therefore, under these new demands, it is of great significance and economic value to provide a building structure that is material-saving, energy-efficient, durable, and offers good comfort, simple installation, and convenient transportation to meet the needs of rural revitalization for villas and small-scale buildings.

[0003] Technical implementation elements:

[0004] The present invention aims to provide a lightweight building structure system and installation method. In terms of structural materials, it avoids the on-site work and large material consumption of wet concrete construction, and also avoids the problems of large steel consumption, construction difficulty and labor intensity of ordinary frame steel structures, resulting in high overall construction costs. At the same time, it avoids the shortcomings of light steel ribbed structures such as vibration and unsatisfactory isolation. In terms of construction, it reduces process complexity, facilitates transportation, and avoids the disadvantages of container houses. These are the goals that the present invention aims to solve.

[0005] To achieve the above objectives, the technical solution of this invention is a modular overlapping lightweight frame building structure, characterized by comprising a multi-story frame building structure system consisting of several multi-story independent modules, several multi-story overlapping modules, a lightweight roof structure, and strip lightweight wall panels. The multi-story independent modules are composed of lightweight floor modules consisting of frame beams, beam-column connection nodes, floor truss beams, and profiled steel sheets, several truss-type lateral support composite columns, and several general vertical support columns. The multi-story overlapping modules are connected to the multi-story independent modules... The overlapping side of the blocks does not have separate support columns, that is, it includes the truss combination lateral support columns or general vertical support columns. At the same time, when the overlapping side is parallel to the floor truss beam in the multi-layer overlapping module floor slab, no frame beam is set on this side. The lightweight roof structure is an independent roof truss structure that is connected to the top of each support column of each multi-layer independent module and multi-layer overlapping module. The strip lightweight partition wall panel is connected to the frame beam by screws through positioning grooves and wall panel damping strips. This constitutes a modular overlapping lightweight frame building structure.

[0006] In one embodiment, the frame beams are U-shaped steel.

[0007] In one embodiment, the floor truss beams are thin-walled light steel truss beams.

[0008] In one embodiment, the connection position of each floor truss beam is such that it is placed between the upper and lower edges of the frame beam.

[0009] In one embodiment, the profiled steel sheet is connected to the upper surface of each floor truss beam and is perpendicular to the floor truss beam.

[0010] In one embodiment, the lightweight floor module is composed of a skin structure formed by thin-walled lightweight steel truss beams, profiled steel sheets, U-shaped steel frame beams, and beam-column connection nodes.

[0011] In one embodiment, the general vertical support column is composed of C-shaped steel or angled C-shaped steel depending on the location.

[0012] In one embodiment, the chord of the truss-type lateral bracing composite column is the C-shaped steel column, and the web members are a planar truss structure composed of tubular profiles and C-shaped steel or angled C-shaped steel through hemispherical nodes.

[0013] In one embodiment, the truss-type lateral bracing composite column is a three-dimensional intersecting planar truss-type lateral bracing composite column composed of two C-shaped steel columns sharing a common angular C-shaped steel support column to form two planar truss structures.

[0014] In one embodiment, one end of the wall panel damping strip is connected to the frame beam via a positioning groove and several screws, while the other part is connected to the side of the strip-shaped lightweight partition wall panel via several screws.

[0015] The advantages of this invention are:

[0016] The core advantage of this invention, a modular overlapping lightweight frame building structure, lies in avoiding the problems of large material consumption, relatively heavy building structure, high construction difficulty, high labor intensity, unfavorable transportation, and high overall cost associated with concrete structures and ordinary frame steel structures. It adopts a modular integrated building structure of light steel ribbed structure and container house, which has the advantages of being lightweight, material-saving, energy-saving, convenient for transportation, simple to construct, low labor intensity, and fast on-site installation. At the same time, it proposes a technical solution to reduce floor vibration and improve building isolation while achieving structural lightweighting.

[0017] The present invention discloses a modular overlapping lightweight frame building structure, which has the following advantages in terms of structural weight reduction: The lightweight floor module proposed in this example uses light steel trusses as floor beams (hereinafter referred to as floor truss beams), which reduces the overall weight of the floor by several times compared with the concrete steel truss floor slabs of ordinary frame steel structures.

[0018] The modular overlapping lightweight frame building structure of the present invention has the following advantages in terms of structural weight reduction: The enclosure structure used in this example includes a lightweight roof truss composed of the prefabricated C-shaped steel truss structure of the inventor's applications 2020216640009 and 202010815648X filed on 2020 / 8 / 9, which further reduces the overall building weight to a greater extent.

[0019] The modular overlapping lightweight frame building structure of the present invention has the following advantages in terms of structural weight reduction: The truss-type anti-lateral support composite column used in this example improves the stress conditions of the frame nodes and vertical support columns. Compared with the rigid connection of the frame nodes of ordinary steel frame structures, the connection is changed to an intersection, which reduces the amount of steel used in the frame nodes and frame columns, and further achieves the purpose of weight reduction.

[0020] The modular overlapping lightweight frame building structure of this invention has the following advantages in terms of structural weight reduction: The truss-type lateral bracing composite column used in this example, by sharing a common angled C-shaped column, is conducive to improving material utilization and facilitating building functional design without hindering window opening. At the same time, the weight reduction of the floor slab and roof, coupled with the high efficiency of the structure, reduces both the vertical and lateral supports of the structure, ultimately achieving the goal of weight reduction.

[0021] This invention discloses a modular, lightweight frame building structure. Its advantages in reducing vibration are as follows: the combination of a frame structure and lightweight floor modules proposed in this example combines the advantages of a light steel ribbed structure while mitigating vibration through structural system modifications. The light steel ribbed structure is characterized by distributed stress. When the floor slab is subjected to concentrated impact loads, theoretically, only the corresponding floor slab truss beams and their associated vertical support columns—the local load-bearing structural system—directly participate in the load-bearing process. Other structures only serve a stabilizing function and do not directly participate in the load-bearing process. Statically, the stress level of the directly load-bearing local structure is relatively high, leading to significant deformation. Dynamically, the dynamic mass of this local structural system is relatively small, and its connection to the foundation is weak. Therefore, when subjected to local impact forces, the vibration is more pronounced. The internal structure of the floor slab in this invention still uses light steel floor truss beams, while the overall structure is a frame structure system. Compared with the light steel closely ribbed structure, under the same local impact load, in terms of static force, except for the floor truss beams, the frame structure still directly participates in the stress. The stress level of other parts except for the floor truss beams is relatively low. In terms of dynamic force, the dynamic mass of the load-bearing system is greatly increased. In addition, the connection between the structural columns and the foundation of the frame structure is relatively strong, all of which are beneficial to reducing the vibration sensation.

[0022] The modular overlapping lightweight frame building structure of this invention has the following advantages in reducing vibration: The profiled steel sheet proposed in this example is placed perpendicular to each floor truss beam to form a connection. Compared with the combination of OSB board and floor truss beam in light steel close-rib structure, a certain bending moment and shear force can be transmitted along the direction of the profiled steel sheet ribs. Depending on the different heights of the profiled steel sheet ribs, a part of the impact load can be transferred to the adjacent floor truss beams to different degrees, thereby reducing the deformation of the floor truss beams themselves. This can also reduce the cumulative deformation of the overall structure, which ultimately helps to reduce vibration.

[0023] The modular, lightweight frame building structure of this invention has the following advantages in reducing vibration: the wall panel damping strips proposed in this example have the following advantages in reducing vibration: since the strip wall panels have a certain weight and strength, one end of the wall panel damping strip is connected to the frame beam through a positioning groove, and the rest is connected to the wall panel through several screws. The number of screws can be determined according to the cross-section of the damping strip and the strength of the wall panel material. By adjusting the cross-section of the damping strip and the number of connecting bolts, the damping force can be adjusted to effectively shorten the vibration decay time, which ultimately helps to reduce vibration.

[0024] The present invention discloses a modular overlapping lightweight frame building structure, which has the following advantages in terms of isolation: the strip lightweight partition wall panels used in this example are all solid materials, which avoids the hollow feeling compared with the wall of the light steel rib structure, and provides better sound insulation and vibration isolation, thus improving the building isolation.

[0025] The present invention discloses a modular overlapping lightweight frame building structure, which has the following advantages in terms of structural simplification: The frame building structure system adopted in this example, consisting of several multi-layer independent modules, several multi-layer overlapping modules, and a lightweight roof structure, leverages the advantages of modular integrated buildings, facilitating simplified structural design and improved integration. At the same time, the combination of the multi-layer independent modules and the multi-layer overlapping modules has the advantage of saving the double floor slabs and double wall panels caused by the double frame structure compared to a purely modular building, which is beneficial for saving materials and simplifying the structure and installation.

[0026] The present invention discloses a modular overlapping lightweight frame building structure, which has the advantage of facilitating installation and construction in that: the structure used in this example consists of several multi-layer independent modules and several multi-layer overlapping modules, wherein each of the lightweight floor slab modules, truss-type lateral bracing composite columns, and lightweight roof structure can be installed on the ground, which greatly reduces the amount of high-altitude installation work, giving full play to the advantages of modular integrated buildings and facilitating installation and construction.
