Description

Technical Field

[0001] The utility model relates to a dry-hanging curtain wall device, which is applied in the fields of building exterior wall decoration and thermal insulation production. Background Art

[0002] In recent years, my country's exterior wall building decoration materials have diversified, meeting people's demand for personalized exterior wall decoration materials. Dry-hang curtain wall systems have attracted much attention and are becoming increasingly widely used. Traditional dry-hang curtain wall systems, mainly including metal curtain wall systems and dry-hang stone systems, use a vertical installation of main purlins with horizontally welded auxiliary purlins (currently, the main purlins use square steel / I-beams, and the auxiliary purlins use square steel / I-beams or angle steel). The installed purlins are then re-measured and returned to the factory for panel processing and preparation according to the re-measured specifications. This means that the panels must be customized, resulting in a long installation process (requiring a construction period of 3-6 months), low efficiency, and cumbersome transportation. The installation of the purlins requires a large amount of materials, which are heavy and expensive. This curtain wall system is heavy and imposes heavy wall loads. Moreover, because each panel is manufactured to a fixed size, with hundreds or even thousands of specifications for each project, it is easy to find panels of the corresponding specifications on site, resulting in significant losses, low installation efficiency, time-consuming and labor-intensive installation, and complex project management. The installation of horizontal auxiliary purlins is generally carried out by welding. After welding, the welding points are painted with anti-rust paint for anti-rust treatment (such as the application of dry-hanging stone curtain wall construction technology for building exterior walls [J]. Yuan Yanqing. Stone, 2024(08)). This on-site treatment method is prone to omissions or inadequate painting, and the surface is generally not cleaned and washed before applying anti-rust paint on site. Compared with the electrogalvanizing process used for purlin materials, this on-site welding point is prone to rust, causing a major safety hazard to the curtain wall system.

[0003] Dry-hung stone curtain walls are widely used in all types of new construction and renovation of existing buildings due to their durability and decorative appeal. However, they are made from non-renewable natural stone, which is cut and processed, wasting a large amount of natural resources and causing irreversible damage to the ecological environment. Dry-hung stone installation methods primarily rely on back bolts and side slotting. In actual applications, it has been found that natural stone, due to its inherent texture, has uncontrollable color variations. Stone installation requires on-site back bolt holes or side slotting (as exemplified by a back-bolt stone curtain wall and its construction method (CN109113239B)). This process is cumbersome, requires a long construction period, and increases uncontrollable human factors, leading to increased safety risks. Therefore, given the limitations of stone in its application, dry-hung systems made of artificial panels are gradually replacing dry-hung stone systems in projects due to their rich and diverse finish colors, customizability, lightweight design (weighing only 1 / 3-1 / 4 of existing dry-hung stone curtain walls), high cost-effectiveness, and ease of construction. For example, CN220827989U discloses a dry-hanging system for calcium silicate decorative panels. This scheme uses a back-bolt mounting structure similar to that of dry-hanging stone. A hole must first be drilled in the back of the calcium silicate board. A first connector is then connected to the board using expansion bolts and nuts, and a second connector is connected to the wall. The first and second connectors are then connected via fixed bolts, forming an effective and secure connection. However, this scheme has several drawbacks: The holes still need to be drilled on-site during application, and the depth of the cut holes and the strength of the board are directly related to the connection safety, which is significantly affected by human factors during construction. The scheme requires the board to be thick to ensure that the back-bolt holes can be drilled to the required depth without damaging the board surface. However, thicker boards can result in heavier boards. Furthermore, each dry-hanging stone product is custom-sized and needs to be factory-fabricated before being transported to the construction site for installation, which is slow and difficult to install.

[0004] Therefore, it has become an urgent task to provide a dry-hanging curtain wall device with simple structure, light weight, saving keel materials, simple installation, flexible use, fast construction, stable structure, high connection strength, safety and reliability. Utility Model Content

[0005] The utility model provides a dry-hanging curtain wall device, which overcomes the shortcomings of the existing dry-hanging curtain wall system, such as complex structure, heavy weight, high cost, cumbersome processing steps, low installation efficiency and long construction period. The device adopts a main keel extending in the vertical direction and distributed at intervals in the transverse direction, and a thin sheet strip-shaped light installation strip with a cross section in the shape of a "J" which extends in the transverse direction and distributed at intervals in the vertical direction. A plurality of anchor holes are distributed at intervals on the two side wings and the plate fixing part of the light installation strip. The light installation strip can be cut according to the size of the plate and connected to the plate. The plate is connected to the main keel through the light installation strip. The device has the advantages of simple structure, light weight, quick installation, material saving, flexible use, high construction efficiency, stable structure, high connection strength, short construction time, good decorative effect, good durability, safety and reliability.

[0006] The technical solution of the utility model is as follows:

[0007] A dry-hang curtain wall device includes a main keel, a light installation strip, a plate, a first connecting member, and a second connecting member. The main keel, the light installation strip, the plate, the first connecting member, and the second connecting member are all in plurality. The main keels are arranged parallel and spaced apart on the outer side wall of a base layer in a transverse direction and each main keel extends from top to bottom along the side wall of the base layer. The main keels are connected to the base layer via the first connecting member.

[0008] The two connecting parts are parallel and spaced apart from each other, and are respectively connected between the upper and lower side edges of the two side wings and the plate fixing part, and the connecting parts are perpendicular to the plate fixing part; each side wing is provided with a plurality of anchor holes distributed at intervals along the extension direction of the side wings or the plate fixing part, the anchor holes on the plate fixing part are long strips extending along the extension direction of the plate fixing part, and the anchor holes on the side wings are circular or long strips extending along the extension direction of the side wings; the connecting anchor nails pass through the anchor holes on the side wings to fix the lightweight mounting strip to the outer wall of the main keel;

[0009] Each plate is connected to the plate fixing portion of the portable installation strip through a second connecting piece, thereby achieving connection with the main keel through the portable installation strip.

[0010] The dry-hanging curtain wall device of the present application uses a main keel extending in the vertical direction and spaced apart in the horizontal direction in combination with a thin strip-shaped light installation strip with a cross section in the shape of a "F" that extends in the horizontal direction and spaced apart in the vertical direction. A plurality of anchor holes are spaced apart on the two side wings and the plate fixing portion of the light installation strip. The light installation strip can be cut according to the size of the plate and connected to the plate. The plate is connected to the main keel through the light installation strip. It has the advantages of simple structure, light weight, material saving, flexible use, high construction efficiency, stable structure, high connection strength, simple and quick plate processing, etc. The dry-hanging curtain wall device only uses a light installation strip with a preferred light structure as the connecting material between the plate and the vertical main keel. Compared with traditional stone materials, there is no need for a horizontal auxiliary keel, which saves auxiliary keel material, effectively reduces weight, reduces installation procedures, shortens installation time, avoids the problems of loose welding points and rust caused by workers' operation, and improves safety performance. The lightweight installation strip adopts a bilateral anchoring structure, which is structurally stable and has a high connection strength with the main keel and the panel. It also has a strong supporting structure. The system is highly safe and lightweight. After testing, the weight of this dry-hanging system is only 1 / 3-1 / 4 of the existing dry-hanging curtain wall system (stone), and the single-point bearing capacity of the connection is 1.5-2 times that of the existing dry-hanging curtain wall system. The system is tested for wind pressure resistance in accordance with the GB / T21086 "Building Curtain Wall" standard and meets the highest level 9 standard requirements. The system has no deformation, damage or other abnormalities, which can meet the use requirements of coastal areas with strong typhoons and has higher safety and reliability. The lightweight installation strip has anchor holes on the side for fixing to the main keel, and anchor holes on the panel fixing part for connecting to the panel. This ensures that the lightweight installation strip can be flexibly cut to any length and can be normally connected to the special-shaped nuts embedded in the panel. It can not only effectively reduce material loss, but also reduce on-site drilling processes. The installation is convenient, simple and quick, which greatly improves construction efficiency. The advantages of using specially designed lightweight installation strips to replace existing auxiliary keels in this case are as follows:

[0011] 1. The lightweight installation strip has a simple structure, light weight, and labor-saving processing. Due to the layout of the anchor holes on its side wings and the plate fixing part, it is flexible to use and can be flexibly cut to the required length. It is easy to align the holes with the plate and can achieve quick connection with the plate. The installation is also labor-saving. The entire construction period of the dry-hang curtain wall device is only 1-2 months;

[0012] 2. The existing connection between the auxiliary purlin and the main purlin is usually welded, and the welding points are prone to rust, resulting in insufficient overall firmness of the dry-hang curtain wall installation. However, the lightweight installation strips in this case can achieve a quick and firm connection with the main purlin through connecting anchor nails, which makes the installation flexible and firm.

[0013] 3. Existing dry-hang curtain wall devices can only install small-sized stone slabs with back bolts and side slots, and the installation efficiency is also low. However, the dry-hang curtain wall device in this case uses lightweight installation strips, which can quickly install large-sized panels.

[0014] The second connecting member includes a plurality of special-shaped nuts and a plurality of fixing anchor bolts arranged in the plate body along the transverse interval. The central axis of each special-shaped nut is arranged perpendicular to the plate. The outer peripheral wall of each special-shaped nut is large at one end and small at the other end. The threaded hole in the special-shaped nut body extends to the end face of the small head end and does not expose the back side wall surface facing inward of the plate. The large head end of the special-shaped nut is a closed structure and is located on the front side of the plate facing outward. The fixing anchor bolt passes through the anchor hole on the fixing part of the plate and is threadedly connected to the threaded hole provided in the special-shaped nut body, thereby firmly fixing the plate and the lightweight installation strip.

[0015] Compared to traditional stone installation, this solution adds embedded pre-embedded special-shaped nuts distributed in the middle of the board. During installation, fixed anchor bolts are used to directly connect the lightweight installation strip to the board. Installation is convenient and does not require on-site grooving or drilling operations, saving the grooving or drilling steps and improving installation and construction efficiency. Special-shaped nuts are standardized and produced in the factory using precision processing equipment, with high processing accuracy and reliability. The single-point strength of the embedded parts is higher than that of similar back bolts, greatly improving safety. The board is made of large-scale artificial boards prefabricated in the factory and cut to the actual required size at the construction site. The board processing efficiency is high and it can be used as soon as it is cut, saving the packaging and transportation links from the factory to the construction site, and avoiding the problem of not being able to find the board on the construction site, reducing the difficulty of construction site management, and the high installation efficiency can effectively shorten the construction period.

[0016] The cross-sectional profile of a special-shaped nut along its axis of symmetry can be a combination of one or more shapes. Special-shaped nuts can be made from stainless steel, iron, aluminum alloy, engineering plastics, resin, and other materials. The large end of the special-shaped nut can be round, oval, square, or polygonal, with a diameter or side length of 8mm-30mm. The small end has a circular, oval, or polygonal cross-section with a diameter or side length of 5mm-20mm. The internal threaded hole in the small end has a diameter of 4mm-15mm. The large end of the special-shaped nut is located inside the sheet material, while the opening of the small end is flush with or slightly below the sheet material surface.

[0017] Special-shaped nuts can be directly embedded into the sheet material during production, or they can be embedded through a secondary process. The secondary process includes drilling a hole, applying adhesive, inserting the special-shaped nut, repairing the hole, and sanding. Hole repair materials can include one or more inorganic adhesives, organic adhesives, putty, or fillers.

[0018] The first connecting member includes a rear embedded plate, connecting bolts and connecting angle brackets. The rear embedded plate is attached to the outer side wall of the base layer and fixed by connecting bolts. One side wing of the connecting angle bracket is welded and fixed to the rear embedded plate, and the other side wing is welded or anchored to the front side wall and / or rear side wall of the main keel.

[0019] The preferred first connecting member has a simple structure and a firm connection. The rear embedded plate is a square or rectangular stainless steel plate or galvanized iron plate with a side length of 150mm-300mm. The thickness of the rear embedded plate is 5mm-12mm. Mounting holes are provided at the four corners of the rear embedded plate. The connecting bolts fix the prefabricated embedded plate to the base wall through the mounting holes. The connecting bolts are mechanical anchor bolts or chemical anchor bolts, and the connecting angle brackets are L-shaped angle brackets made of stainless steel or galvanized iron. The first connecting member is simple and quick to install, and is safely and reliably connected to the base layer.

[0020] The length of each anchor hole in the plate fixing part is 15mm-100mm, the width is 5mm-13mm, and the distance between two adjacent anchor holes is 10mm-60mm.

[0021] This preferred solution can ensure that the lightweight installation strip can be cut to any length and can ensure the normal connection between the lightweight installation strip and the special-shaped nuts embedded in the plate. At the same time, it also ensures the normal connection between the side wings and the main keel. This not only effectively reduces material loss, but also reduces on-site drilling processes. The installation is convenient, simple and fast, which greatly improves construction efficiency.

[0022] The light installation strips are made of metal material, resin material or a composite material of resin and reinforced mesh. The length of each light installation strip extended in the transverse direction is 20mm-50mm longer than the length of the side of the plate connected to the light installation strip; both transverse ends of the light installation strip extend out of the transverse edges of the plate connected to the light installation strip by more than 10mm.

[0023] The preferred setting allows the installation location to be located at the plate seam when the side wings of the lightweight installation strip are connected to the main keel, which leaves space for installation, facilitates workers to install and use power tools, improves installation efficiency, and ensures the reliability of the installation of the connecting anchor nails, ensuring a firm installation.

[0024] The connecting anchors are self-drilling screws.

[0025] Drilling self-tapping screws do not require pre-drilling, and are quick and efficient to install, with reliable connection strength.

[0026] A layer of thermal insulation material is provided between the main keel and the base layer, between the rear embedded plate and the base layer, and between the plate and the base layer.

[0027] Different types of insulation materials can be selected as needed to meet the energy-saving design requirements of different buildings. Reduce the energy consumption and carbon emissions of buildings. The insulation material (insulation material layer A 9) provided between the base layer and the plate is generally fixed on the surface of the base layer. The insulation material can be adhered to the surface of the base layer with an adhesive material and fixed with anchor bolts. Hard insulation material (insulation material layer B10) can be used to isolate the post-embedded plate from the base layer. The insulation material layer between the main keel and the base layer is insulation material layer C11. The insulation materials of insulation material layer A, insulation material layer B and insulation material layer C can be selected from organic flame-retardant insulation materials, inorganic insulation materials, organic-inorganic hybrid insulation materials, rock wool or vacuum insulation panels, etc.

[0028] The board is cut from prefabricated artificial board, the front surface of the board is provided with a decorative layer, which is a paint finishing layer, a decorative sheet layer or a metal plate layer, and the back surface of the board is provided with a waterproof coating.

[0029] Panels with a metal sheet layer can replace traditional metal panels. Since traditional metal panels are installed using a dry hanging solution, they are required to have high strength and stiffness to avoid deformation. The thickness is generally 2.0mm-3.0mm, but the metal sheet layer used in artificial panels is only 0.3mm-1.0mm thick, and has high strength, good stiffness, and is not easy to deform, which greatly saves metal materials and conserves resources. Panels with a stone-like paint finishing layer can replace traditional stone. The panels are light and can be designed and installed in large sizes to meet the diverse design styles of buildings.

[0030] A sealing material layer for sealing and waterproofing is provided in the gap between adjacent plates. The sealing material layer is a silicone adhesive layer, an organic resin layer, an organic elastomer layer or an inorganic sand powder layer.

[0031] Filling the gaps with sealing materials can improve the overall sealing and waterproof performance of the dry-hanging curtain wall installation.

[0032] The cross section of the main keel is O-shaped or I-shaped, and the material is hot-dip galvanized iron or aluminum alloy.

[0033] The thickness of the main keel plate is 8mm-20mm, which is light in weight and high in strength. It can effectively reduce the load of the building and improve safety performance.

[0034] The installation method of the dry-hanging curtain wall device comprises the following steps performed in sequence:

[0035] 1) Distribute the main keels in parallel and at intervals on the outer side wall of the base layer and fix them with a first connecting member, so that each main keel extends from top to bottom along the side wall of the base layer;

[0036] 2) Cut the artificial board to the appropriate size according to the design requirements of the grid layout and the actual main keel distribution spacing;

[0037] 3) Cut the portable installation strips so that the transverse extension length of each portable installation strip is 20 mm to 50 mm longer than the transverse extension length of the plate connected to the portable installation strip;

[0038] 4) Use a second connecting piece to connect each portable installation strip to the corresponding plate, and ensure that both lateral ends of the portable installation strip extend more than 10 mm beyond the lateral edges of the plate;

[0039] 5) Use connecting anchors to connect the two ends of the lightweight installation strip to the main keel, and make the lightweight installation strip perpendicular to the main keel, so as to fix the plate on the side wall of the base layer, and control the gap between two adjacent plates to meet the design requirements.

[0040] The dry-hanging curtain wall device of the present application has the advantages of simple installation method, solid structure, quick construction, low management requirements, reliable installation quality, short installation period (only 1-2 months), and high efficiency.

[0041] The installation method of the dry-hanging curtain wall device further includes step 6) cleaning the gaps between adjacent panels and filling the gaps with a sealing material layer for sealing and waterproofing.

[0042] Filling the gaps with the sealing material layer can improve the overall sealing and waterproof performance of the dry-hanging curtain wall device, prevent water from the external environment from entering and damaging the panels, improve the durability and stability of the dry-hanging curtain wall device, and prevent external rainwater from entering the wall, causing wall leakage and affecting the quality of the indoor living environment.

[0043] Compared with the prior art, the utility model application has the following advantages:

[0044] 1) The dry-hang curtain wall device of the present application uses a main keel extending in the vertical direction and spaced apart in the transverse direction, in combination with a thin, strip-shaped, cross-section shaped like a "J" character, extending in the transverse direction and spaced apart in the vertical direction. Multiple anchor holes are spaced apart on both side wings and the panel fixing portion of the light installation strip. The light installation strip can be cut to the size of the panel and connected to the panel. The panel is connected to the main keel via the light installation strip. The device has the advantages of simple structure, light weight, quick installation, material saving, flexible use, high construction efficiency, stable structure, high connection strength, short construction time, good decorative effect, good durability, safety and reliability.

[0045] 2) Embedded pre-buried special-shaped nuts are added to the plate at the midpoint distribution.
