Description

Technical Field

[0001] The invention belongs to the field of assembled building engineering, and in particular relates to a prefabricated reversible assembled multifunctional lattice filling wall and an installation method thereof. Background Art

[0002] With the comprehensive development of today's society and the improvement of people's quality of life, the demand for living environment, building quality, housing safety and comfort is constantly increasing. The original planning concept and design level are very different from the needs of modern lifestyles. The structure gradually ages over time, resulting in the current status of housing far from meeting people's needs. In order to adapt to the ever-changing needs of the people and improve the urban environment and functions, urban renewal has become one of the national development strategies. Therefore, it is an inevitable trend in the development of the construction industry to study reversible multifunctional structural systems with sustainable development characteristics with the goal of meeting people's increasing needs for a better life.

[0003] Building walls are the components that have the greatest impact on structural performance and house functions. They not only significantly affect the vertical and horizontal bearing capacity and lateral stiffness of the structure, but also have a decisive influence on the flexibility of space use, the sound insulation and heat insulation performance of the room, and the difficulty of laying equipment pipelines.

[0004] Nowadays, residents' demands for residential space are becoming more diversified and personalized. In order to expand the usable space of the house or even change the house type to meet their own requirements, they choose to remove some walls during the decoration stage. The construction process is time-consuming and laborious and interferes with the normal lives of other residents. Some people even remove load-bearing walls, which seriously affects the safety of the house and even causes engineering accidents.

[0005] In addition, with the implementation of green building standards, the ability of residential walls to block environmental noise and impact noise has become increasingly concerned. Therefore, improving the sound insulation performance of buildings has become an important demand of the people. In order to improve the sound insulation capacity of residential buildings, the following common practices are commonly used: 1. For environmental sound insulation, new heavy walls are built, and high-thickness and high-density wall materials are used to improve the sound insulation. This method is simple and efficient, but the thickness of heavy walls is too large and will occupy the use space. The heavy brick walls will increase the load of the house and have higher bearing capacity requirements. In addition, the wall masonry process is wet work, and the sound insulation effect of impact noise is also general. 2. New lightweight walls are built, such as the most common light steel keel gypsum board wall. This method has a small wall weight and a short construction time, but the wall sound insulation, heat insulation and bearing capacity are all weak. 3. The construction of a composite wall of heavy walls and light walls usually involves making a layer of lightweight sound-absorbing surface on the basis of the original solid wall to achieve the effect of sound insulation enhancement. This approach can achieve good sound insulation effects and is the most commonly used, but the layout of the sound insulation wall needs to be based on the position of the original wall and cannot be flexibly arranged, which cannot meet people's needs for flexible space layout.

[0006] In the house decoration project, the reasonable layout and construction method of equipment pipelines have a direct impact on the labor intensity and noise and dust pollution degree of the construction process and the convenience of use after delivery. Common pipeline installation methods are as follows: 1. Laying pipelines directly on the floor slab. This installation method is the simplest and the laying length is short, so the laying cost is low. However, pipeline inspection and maintenance are not convenient, and maintenance requires prying the ground, causing economic losses. 2. Laying pipelines in grooves on the wall. This method is also low-cost and convenient for maintenance and inspection, but the construction of grooves causes serious noise pollution, and will damage the existing walls, affecting the bearing capacity and seismic resistance of the load-bearing walls, especially horizontal grooves in the wall, which are prohibited by relevant regulations. 3. Suspending pipelines under the building is convenient for pipeline inspection and maintenance, and pipeline problems are easiest to find, but this type of pipeline is difficult to install, expensive, reduces the height of the residential floor, and building pipelines on the top is not beautiful, and often requires a suspended ceiling. In response to the above problems, reserving pipeline holes and grooves in the wall may be a feasible solution.

[0007] At present, China is vigorously promoting prefabricated buildings, among which prefabricated walls are divided into load-bearing walls and infill walls. For load-bearing concrete walls, they are large in size and heavy in weight, making it difficult to achieve flexible assembly and layout. The wall has a single function and poor sound insulation and heat insulation performance. Although it is a prefabricated wall, it does not have the function of sustainable reversible transformation, nor can it meet the user's requirements for flexible space layout. For prefabricated infill walls, there are currently a variety of mature products with the advantages of light weight, heat insulation and sound insulation, and easy installation, such as ALC wall panels, polystyrene boards, paper honeycomb multifunctional boards, and various sandwich multifunctional boards. This type of wall panel contributes little to the structural bearing performance, and it is difficult to meet the needs of low-cost reversible adjustment and convenient pipeline layout and maintenance functions.

[0008] Therefore, developing a reversible assembled multifunctional wall panel that can simultaneously achieve load-bearing reinforcement, sound insulation and heat insulation, flexible and adjustable space, and convenient pipeline layout and maintenance has important practical significance for the continuous improvement of the function and environment of the house itself and the sustainable development of urban and rural construction.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example 1

[0047] See attached Figure 1-8 The present embodiment discloses a prefabricated reversible assembled multifunctional lattice filling wall, comprising a prefabricated lattice frame wall unit 2, a connecting anchor bolt 3, a sound insulation and heat insulation partition board 4, a sound insulation and heat insulation filling block 5, a hard rubber sheet 6 and a groove-type self-adhesive cover plate 7.

[0048] The prefabricated lattice frame wall unit 2 can be transported to each floor by convenient transportation methods such as elevator transportation. The prefabricated lattice frame wall unit 2 includes an ordinary frame wall unit 2-1. In order to facilitate the assembly and elevator transportation of the frame wall unit, the outer dimensions and weight of the frame wall unit are controlled. The height of the ordinary frame wall unit 2-1 should be 1 / 3 to 2 / 3 of the floor height, usually in the form of two floors and one span or three floors and two spans; the thickness is selected from 80mm to the column width according to the wall function; the width should be 0.6m to 1.5m. The ordinary frame wall unit 2-1 is composed of left and right columns 4-1 and multi-layer beams 4-2. The width of the left and right columns 4-1 should be 80mm to 300mm, and the height of the beam 4-2 should be 60mm to 120mm.

[0049] The prefabricated lattice frame wall unit 2 of the present invention is connected to the main frame of the building and the frame wall units to each other in a simple, convenient and reliable manner by bolting through the reserved holes 4-3. The reserved hole grooves are arranged on the surfaces of the left and right columns 4-1 and the crossbeam 4-2, and the reserved holes 4-3 are arranged in the reserved hole grooves. The reserved holes 4-3 are countersunk holes. The reserved holes 4-3 are provided with cylindrical pits with a diameter of 40mm-50mm and a depth of 20mm at the inner end of the lattice opening, which is convenient for nuts and pads to be embedded for invisible connection. The adjacent ordinary frame wall units 2-1 are connected by bolts.

[0050] As a preferred embodiment of the present invention, it also includes a door frame unit 3-1 and a window frame unit 3-2. The ordinary door frame unit 3-1 is reserved with door and window openings. The door frame unit 3-1 and the window frame unit are embedded in the door and window openings. The window frame unit 3-2 is a rectangular frame with reserved holes 4-3 on the frame. The upper and lower parts are combined with ordinary frame wall units 2-1 with suitable sizes. The door frame unit 3-1 is a П frame, the lower part is sealed by a metal plate 3-3, the metal plate 3-3 is provided with reserved fixing bolt holes, and the upper part is combined with ordinary frame wall units 2-1 with suitable sizes. The door frame unit 3-1 and the window frame unit 3-2 are determined according to the design size of the door and window openings, and the width should not be greater than 1.5m.

[0051] In order to prevent the door frame unit 3-1 and the window frame unit 3-2 from being damaged due to insufficient local rigidity during transportation and installation, an X-shaped cross cable may be inserted into the diagonal reserved hole 4-3.

[0052] The above-mentioned prefabricated lattice frame wall unit 2 can be selected in different sizes and materials, as well as the number of spaces according to the design objectives, rigidity requirements, and space conditions. The material of the prefabricated lattice frame wall unit 2 used is fiber concrete, reinforced concrete, steel, aluminum alloy or wood. When concrete material is used, the concrete strength grade should not be lower than C20; when reinforced concrete material is used, the main reinforcement can be 3mm-5mm steel wire, and the stirrups can be closed steel hoops or bolt stirrups welded. When metal plate material is used, the wall thickness is not less than 2mm.

[0053] As a preferred embodiment of the present invention, the diameter of the connecting anchor bolt 3 is selected to be M20-M25, and a bolt pad 5-2 is provided on the outside of the connecting bolt 5-1, and the thickness of the bolt pad 5-2 is not less than 4mm. According to the position and size of the reserved hole 4-3 of the prefabricated lattice frame wall unit 2, a wall hole 6-1 is drilled at the corresponding position of the beam and column of the room to realize the bolt connection between the filling wall and the frame as a whole.

[0054] As a preferred embodiment of the present invention, the sound insulation and heat insulation partition 4 can be made of a single whole metal plate, a common sandwich sound insulation material board or a conventional light wall. The sound insulation and heat insulation filling block 5 is made of a conventional sound insulation and heat insulation porous material.

[0055] As a preferred embodiment of the present invention, a hard rubber sheet 6 is padded at the bolt connection gap of the prefabricated lattice frame wall unit 2, and its width is equal to the thickness of the ordinary frame wall unit 2-1, and the thickness is preferably 2 to 10 mm. The connection method of bolts + rubber sheet pads is adopted, which not only helps to compact the gap and improve the environmental sound insulation performance, but also can significantly improve the energy consumption capacity of the structure under earthquake action. At the same time, the wall is easy to disassemble, which is convenient for reversible assembly and position adjustment.

[0056] A wiring pipeline is arranged inside the groove-shaped self-adhesive cover plate 7. The size of the groove-shaped opening of the groove-shaped self-adhesive cover plate 7 should be larger than the diameter of the pipeline. Self-adhesives 8 are arranged at both ends of the groove-shaped opening. After the pipeline is inserted into the pipeline in the reserved hole 4-3, the groove-shaped self-adhesive cover plate 7 is pasted on the crossbeam 4-2 at the space of the lattice structure to turn the pipeline from light to dark. The groove-shaped cover plate is provided with self-adhesives 8, and the cover plate can be improved into a form that can be flipped with one side divided, which is convenient for the maintenance and inspection of the pipeline, reduces the design difficulty of the pipeline inside the house, realizes the flexible arrangement of the pipeline, reduces the labor intensity and construction difficulty of inserting the pipeline, and is also convenient for the inspection and maintenance of the pipeline in the later stage.

[0057] In the above technical scheme, the prefabricated and assembled multifunctional lattice filling wall can be customized and assembled through different materials and scales to realize the functions of strengthening the bearing capacity, improving the seismic performance, heat insulation and sound insulation, and partitioning the space for local use in new construction and renovation projects. If the interlayer anti-lateral displacement stiffness is insufficient, several lattice walls can be added for reinforcement. If the required stiffness improvement is too large, the stiffness requirements can be met by adjusting the width of the columns and the number of beams. For the reinforcement situation where the bearing capacity of the local beam does not meet the requirements, when the bearing capacity of the upper beam is insufficient, a prefabricated and assembled multifunctional lattice filling wall 1 can be directly set at the bottom of the beam for support; when the bearing capacity of the lower beam is insufficient, first paste a high-strength concrete full-length plate with a height of 100mm-200mm, and then install the prefabricated and assembled multifunctional lattice filling wall of suitable size. The choice of wall and wall size can flexibly select the reinforcement plan.

[0058] like Figure 9-12 As shown, if the whole wall is partitioned by a prefabricated multifunctional lattice filling wall 1, it can be flexibly selected according to the actual needs such as structural lateral stiffness reinforcement requirements, space usage requirements, sound insulation and heat insulation requirements:

[0059] like Fig. 9 As shown, an embodiment of a single-layer narrow partition type fully soundproof and heat-insulating filling block wall is provided, in which the prefabricated lattice frame wall unit 2 is completely filled with soundproof and heat-insulating filling blocks 5. The single-layer narrow partition type wall of this embodiment is relatively thin in thickness, can play the role of a lightweight partition wall and decoration, and also has a certain rigidity.

[0060] like Fig.10 As shown, an embodiment of a single-layer wide partition partial sound insulation and heat insulation filling block wall is provided, in which sound insulation and heat insulation filling blocks 5 are partially filled in the prefabricated lattice frame wall unit 2. The single-layer wide partition wall of this embodiment is relatively thick, which can effectively improve the bearing capacity and earthquake resistance of the structure.

[0061] like Fig.11As shown, an embodiment of a double-layer sandwich partition wall without soundproofing and heat-insulating filling blocks is provided, in which no soundproofing and heat-insulating filling blocks 5 are arranged. The double-layer sandwich partition wall is composed of two prefabricated lattice frame wall units 2 with soundproofing and heat-insulating partition boards 4 added between the walls, so as to further enhance the soundproofing and heat-insulating capabilities of the wall.

[0062] like Fig.12 As shown, a single-layer frame wall and single-layer core board partition without sound insulation and heat insulation filling block wall embodiment is provided, wherein the single-layer frame wall and single-layer core board partition wall is composed of a prefabricated lattice frame wall unit 2 wall and a sound insulation and heat insulation partition board 4, which has good sound insulation and heat insulation capabilities while being thinner and lighter. In actual projects, owners and developers can flexibly select the function of the wall according to different needs. For example, a high-strength double-layer sandwich partition wall can be used in the partition wall of a newly built structure, which has a good heat insulation and sound insulation effect.

[0063] Example 2

[0064] When it is necessary to use prefabricated frame wall units to improve the bearing capacity and seismic resistance of structures and components, a suitable reinforcement scheme for prefabricated lattice frame wall units 2 can be selected according to the actual reinforcement requirements. For example, if the interlayer anti-lateral displacement stiffness is insufficient, several lattice walls can be added for reinforcement. If the required stiffness increase is too large, the stiffness requirements can be met by adjusting the width of the columns 4-1 and the number of beams 4-2. For reinforcement situations where the bearing capacity of local beams does not meet the requirements, when the bearing capacity of the upper beam is insufficient, the prefabricated assembled multifunctional lattice filling wall support can be directly set at the bottom of the beam; when the bearing capacity of the lower beam is insufficient, first paste a high-strength concrete full-length plate with a height of 100mm-200mm, and then install the prefabricated assembled multifunctional lattice filling wall of a suitable size.

[0065] Example 3

[0066] This embodiment discloses a method for installing a prefabricated reversible assembled multifunctional lattice filling wall, comprising the following steps:

[0067] S01. The prefabricated lattice frame wall unit 2 is transported indoors, and its assembly is completed according to the needs of the prefabricated multifunctional lattice filling wall;

[0068] S02. According to the position and size of the prefabricated lattice frame wall unit 2 reserved holes 4-3, the corresponding parts of the beams and columns of the room are drilled into the wall surface 6-1;

[0069] S03. The prefabricated lattice frame wall unit 2 is moved to a predetermined position, bolted at the connection position by connecting the anchor bolt 3, the pipeline is inserted into the reserved hole 4-3, and the grooved self-adhesive cover plate 7 is pasted;

[0070] S04. Further construction of the assembled prefabricated lattice frame wall is carried out according to the actual usage:

[0071] A. When the lattice space is needed, only the surface layer of the ordinary frame wall unit 2-1 is decorated without filling;

[0072] B. When it is necessary to improve the sound insulation and heat insulation performance, apply non-polluting inorganic glue on the inner wall of the lattice, and then fill it with sound insulation and heat insulation filling blocks 5 of equal thickness;

[0073] C. When the infill wall only needs to hang light objects, use foam concrete for filling;

[0074] D. When the filling wall needs to hang heavy objects such as wall cabinets, it can be directly anchored through the reserved holes 4-3, or solid bricks can be partially laid in the lattice space to improve its bearing capacity.

[0075] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
