Description

Technical Field

[0001] The invention relates to a dry hanging curtain wall device and an installation method thereof, which are applied in the field of building exterior wall decoration and thermal insulation production. Background Art

[0002] In recent years, the diversified development of building decoration materials for exterior walls in my country has met people's personalized needs for exterior wall decoration materials. The dry hanging curtain wall system is an exterior wall decoration system that has received much attention and has been increasingly widely used in recent years. Traditional dry hanging curtain wall systems mainly include metal curtain wall systems and dry hanging stone systems. The keel is installed by vertically installing the main keel in combination with horizontally welding the auxiliary keel (the existing main keel uses square steel / I-beam, and the auxiliary keel uses square steel / I-beam or angle steel). Then the installed keel is re-measured, and then returned to the factory for processing and material preparation of the plate according to the re-measured specifications. That is, the plate needs to be customized, and the entire installation process takes a long time (requiring a construction period of 3-6 months), is inefficient, and is cumbersome to transport. The materials used to install the keel are large, heavy, and expensive. This curtain wall system is heavy and has a large wall load. Moreover, since each plate is processed to a fixed size, each project has hundreds or thousands of specifications. It is easy to find the corresponding specification plate on site, resulting in large losses, low installation efficiency, time-consuming and labor-intensive, and difficult project management. The installation of horizontal auxiliary keels 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 missing 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 keel materials, this on-site welding point is prone to rust, causing a major safety hazard to the curtain wall system.

[0003] Dry-hanging stone curtain walls are widely used in all kinds of new construction and renovation of existing buildings due to their durability and decorative grade. However, they are made of non-renewable natural stone as raw materials for cutting and processing, which wastes a lot of natural resources and causes irreversible damage to the ecological environment. The installation method of dry-hanging stone is mainly back bolts and side grooves. In actual applications, it is found that due to its own natural texture characteristics, the color difference of natural stone is uncontrollable. Stone installation requires back bolt holes or side grooves on site (such as a back bolt stone curtain wall and its construction method (CN109113239B)), which has cumbersome procedures, long construction period, and increases uncontrollable factors and safety risks. Therefore, in view of the limitations of stone in application, the dry-hanging system of artificial board has gradually replaced the stone dry-hanging system in engineering with its rich and diverse finishing colors and customizability, lightweight (weight is only 1 / 3-1 / 4 of the existing dry-hanging stone curtain wall), high cost performance, and easy construction. For example, CN220827989U discloses a calcium silicate decorative panel dry hanging system, which adopts a back bolt installation structure that is relatively close to dry hanging stone. It is necessary to first open a hole on the back of the calcium silicate board, connect the first connecting piece to the calcium silicate board with an expansion bolt and a nut, connect the second connecting piece to the wall, and connect the first connecting piece to the second connecting piece by a fixing bolt to form an effective and firm connection. However, the disadvantages of this scheme are: it is still necessary to open holes on site during application, and the depth of the cut hole and the strength of the plate are directly related to the connection safety, and the human factors of construction have a greater impact; this scheme requires that the plate must have a thicker thickness to ensure that the back bolt opening meets the requirements without damaging the plate surface, and the thicker plate will cause the plate to be heavier; in addition, the specifications of each dry hanging stone product are customized sizes, which need to be processed in the factory and transported to the construction site for installation, which is slow and difficult to construct.

[0004] Therefore, it is urgent to provide a dry-hanging curtain wall device and its installation method which are simple in structure, light in weight, save in keel materials, simple in installation, flexible in use, quick in construction, stable in structure, high in connection strength, safe and reliable. Summary of the invention

[0005] The present invention provides a dry - hanging curtain wall device and an installation method thereof, which overcome the disadvantages 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. It uses main keels extending along the vertical direction and distributed at intervals along the horizontal direction in cooperation with thin - strip lightweight installation strips with a "J" - shaped cross - section extending along the horizontal direction and distributed at intervals along the vertical direction. A plurality of anchoring holes are distributed at intervals on both side wings and the plate fixing part of the lightweight installation strip. The lightweight installation strip can be cut according to the size of the plate and connected to the plate, and the plate is connected to the main keel through the lightweight installation strip, having the advantages of simple structure, light weight, fast installation, material saving, flexible use, high construction efficiency, stable structure, high connection strength, short construction time, good decorative effect, good durability, safety and reliability, etc.

[0006] The technical solution of the present invention is as follows:

[0007] A dry - hanging curtain wall device includes main keels, lightweight installation strips, plates, first connectors, and second connectors. The numbers of the main keels, lightweight installation strips, plates, first connectors, and second connectors are all multiple. Each main keel is horizontally and parallelly distributed at intervals on the outer side wall of the base layer, and each main keel extends from top to bottom along the side wall of the base layer. The main keel and the base layer are connected by the first connector;

[0008] Each lightweight installation strip includes two side wings, two connecting parts, and a plate fixing part. The side wings, the plate fixing part, and the connecting parts are all long - strip sheet - like structures. The two side wings are arranged parallelly at intervals up and down and each extends along the horizontal direction and is attached to the outer side wall of the main keel, and intersects with the main keel perpendicularly. The plate fixing part is arranged between the two outer side wings and is parallel to the side wings, and the projection of the plate fixing part on the outer side wall of the main keel is located between the two side wings. The two connecting parts are arranged parallelly at intervals up and down and are respectively connected between the upper and lower edges of the two side wings and the plate fixing part, and the connecting parts are perpendicular to the plate fixing part; A plurality of anchoring holes are opened on each of the side wings and the plate fixing part at intervals along the extending direction of the side wing or the plate fixing part. The anchoring holes on the plate fixing part are long - strip - shaped extending along the extending direction of the plate fixing part, and the anchoring holes on the side wings are circular or long - strip - shaped extending along the extending direction of the side wing; Connecting anchor bolts pass through the anchoring holes on the side wings to fix the lightweight installation strip on the outer side wall of the main keel;

[0009] Each plate is respectively connected to the plate fixing part of the lightweight installation strip through the second connector, so as to be connected to the main keel through the lightweight installation strip.

[0010] The dry-hanging curtain wall device of the present application uses main keels extending in the vertical direction and distributed at intervals in the horizontal direction in cooperation with thin strip-shaped lightweight installation strips with a "ji" character cross-section extending in the horizontal direction and distributed at intervals in the vertical direction. A plurality of anchoring holes are distributed at intervals on both side wings and the plate fixing part of the lightweight installation strip. The lightweight 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 lightweight installation strip, which has the advantages of simple structure, light weight, material saving, flexible use, high construction efficiency, stable structure, high connection strength, and simple and fast plate processing. This dry-hanging curtain wall device only uses the lightweight installation strip with a preferred lightweight structure as the connecting material between the plate and the vertical main keel. Compared with traditional stones, it does not require horizontal auxiliary keels, saves auxiliary keel materials, effectively reduces the weight, reduces the installation process, shortens the installation time, avoids the problems of loose solder joints and rust caused by worker operation, and improves the safety performance. The lightweight installation strip adopts a double-sided anchoring structure, with stable structure, high connection strength with the main keel and the plate, and a strong supporting structure itself. The safety of the system is high and the weight is light. 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 at the connection is 1.5 - 2 times that of it. Moreover, the system conducts anti-wind pressure performance classification tests in accordance with the standard of GB / T21086 "Building Curtain Wall", reaching the highest standard requirement of level 9, and there are no abnormal conditions such as any deformation or damage to the system, which can meet the use requirements in strong typhoon areas along the coast, and the safety and reliability are higher. Anchoring holes are opened on the side wings of the lightweight installation strip for fixing with the main keel, and anchoring holes are opened on the plate fixing part for connecting with the plate, ensuring 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 plate. This can not only effectively reduce material loss, but also reduce the on-site drilling process, and the installation is convenient, simple and fast, greatly improving the construction efficiency. The advantages of using the specially designed lightweight installation strip in this case to replace the existing auxiliary keel are as follows:

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

[0012] 2. The connection between the existing auxiliary keel and the main keel uses welding, and its solder joints are prone to rust, resulting in insufficient overall firmness of the dry-hanging curtain wall device. However, the lightweight installation strip in this case can achieve rapid and firm connection with the main keel through connecting anchor bolts, and the installation is flexible and firm;

[0013] 3. The existing dry-hanging curtain wall device can only install small-sized stone slabs with back bolts and side grooving, and the installation efficiency is also low. However, due to the adoption of the lightweight installation strip in the dry-hanging curtain wall device in this case, it can rapidly install large-sized plates.

[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 lateral intervals. The central axis of each special-shaped nut is arranged perpendicular to the plate. The outer peripheral wall of each special-shaped nut has one end larger than 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 with the threaded hole provided in the special-shaped nut body, thereby firmly fixing the plate and the portable installation strip.

[0015] Compared with traditional stone installation, this solution adds embedded pre-embedded special-shaped nuts to the midpoint distribution of the board. During installation, fixed anchor bolts are used to directly connect the lightweight installation strip to the board. It is easy to install and does not require on-site slotting or drilling operations, saving slotting or drilling steps and high installation and construction efficiency. Special-shaped nuts are standardized in the factory through precision processing equipment, with high processing accuracy and reliability. The single-point strength of the embedded part is higher than that of similar back bolts, and the safety is greatly improved. The board is a large-sized artificial board prefabricated in the factory and cut at the construction site according to the actual required size. The board has high processing efficiency and can be used 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 management on the construction site, and has high installation efficiency, which can effectively shorten the construction period.

[0016] The outer contour line of the cross section of the special-shaped nut along the axis of symmetry can be a combination of one or more shapes. The material of the special-shaped nut can be stainless steel, iron, aluminum alloy, engineering plastics, resin, etc. The large head end of the special-shaped nut is round, oval, square or polygonal, with a diameter or side length of 8mm-30mm; the outer cross section of the small head end is round, oval or polygonal, with a diameter or side length of 5mm-20mm, and the diameter of the internal threaded hole of the small head end is 4mm-15mm. The large head end of the special-shaped nut is located inside the plate, and the opening of the small head end is flush with the surface of the plate or slightly lower than the surface of the plate.

[0017] Special-shaped nuts can be directly embedded in the plate during production, or they can be embedded by secondary processing. The secondary processing embedding process includes opening a hole, applying adhesive in the hole, inserting the special-shaped nut, hole repairing, sanding and other processes. The hole repairing material can be one or more of inorganic adhesive materials, organic adhesive materials, putty, filling materials, etc.

[0018] The first connecting member includes a rear embedded plate, connecting bolts and connecting angle codes. The rear embedded plate is attached to the outer wall of the base layer and fixed by connecting bolts. One side wing of the connecting angle code 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 code is an L-shaped angle code 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.

[0020] The length of each anchor hole of 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, while also ensuring the normal connection between the side wings and the main keel. This not only effectively reduces material loss, but also reduces on-site drilling procedures, making installation convenient, simple and quick, and greatly improving construction efficiency.

[0022] The portable installation strip is made of a composite material composed of metal material, resin material or resin and reinforcing mesh cloth. The length of each portable installation strip extending in the lateral direction is 20mm-50mm longer than the length of the side of the plate connected to the portable installation strip in the lateral direction. Both lateral ends of the portable installation strip extend out of the lateral edges of the plate connected to the portable installation strip by more than 10mm.

[0023] The preferred setting allows the installation site to be located at the board seam when the side wing of the lightweight installation strip is 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 drill-tailed self-tapping screws.

[0025] Drill-type self-tapping screws do not require pre-drilling, are installed promptly and efficiently, and have 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 thermal 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 thermal insulation material (thermal insulation material layer A 9) provided between the base and the plate is generally fixed on the surface of the base, and the thermal insulation material can be adhered to the surface of the base with an adhesive material, and then fixed with anchor bolts. Hard thermal insulation material (thermal insulation material layer B10) can be used to isolate the rear buried plate from the base. The thermal insulation material layer between the main keel and the base is thermal insulation material layer C11. The thermal insulation materials of thermal insulation material layer A, thermal insulation material layer B and thermal insulation material layer C can be selected from organic flame retardant thermal insulation materials, inorganic thermal insulation materials, organic-inorganic hybrid thermal 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, the decorative layer 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 metal sheet layers can replace traditional metal panels. Traditional metal panels are installed using a dry hanging solution, which requires them 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 arranged in the gap between two 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 waterproofing 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. It is light in weight and high in strength. It can effectively reduce the load on 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 piece, and each main keel extends from top to bottom along the side wall of the base layer;

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

[0037] 3) Cut the lightweight installation bars so that the length of each lightweight installation bar extending horizontally is 20 mm - 50 mm longer than the side length of the board connected to the lightweight installation bar extending horizontally.

[0038] 4) Connect each lightweight installation bar to the corresponding board with a second connector, and make both ends of the lightweight installation bar horizontally extend more than 10 mm beyond the horizontal edges of both ends of the board.

[0039] 5) Connect both ends of the lightweight installation bar to the main keel with connecting anchor bolts, and make the lightweight installation bar perpendicular to the main keel, so as to install and fix the board on the base side wall, and control the gap between two adjacent boards to meet the design requirements.

[0040] The installation method of the dry - hanging curtain wall device of this application is simple, the structure is firm, the construction is fast, the management requirements are low, the installation quality is reliable, the installation period is short (only 1 - 2 months), and the efficiency is high.

[0041] The installation method of the dry - hanging curtain wall device described above further includes step 6) cleaning the gap between two adjacent boards, and filling a sealing material layer in the gap for sealing and waterproofing.

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

[0043] Compared with the prior art, this invention application has the following advantages:

[0044] 1) The dry - hanging curtain wall device of this application uses a main keel extending along the vertical direction and distributed at intervals horizontally and a thin - sheet - shaped lightweight installation bar with a "J" - shaped cross - section extending along the horizontal direction and distributed at intervals vertically. A plurality of anchoring holes are distributed at intervals on both side wings and the board fixing part of the lightweight installation bar. The lightweight installation bar can be cut according to the size of the board and connected to the board. The board is connected to the main keel through the lightweight installation bar, and has the advantages of simple structure, light weight, fast installation, material saving, flexible use, high construction efficiency, stable structure, high connection strength, short construction time, good decorative effect, good durability, safety and reliability, etc.

[0045] 2) Embedded embedded special - shaped nuts are added at the mid - point of the board. During installation, the lightweight installation bar can be directly connected to the board with fixed anchor bolts. The installation is convenient, and there is no need for on - site grooving or hole - opening operations, and the installation and construction efficiency is high.
