Description

Technical Field

[0001] The invention belongs to the technical field of special-shaped glass curtain walls of buildings, and in particular relates to a folded-line environmentally friendly sound-insulating and heat-insulating glass curtain wall. Background Art

[0002] The decorative glass is hung on the building's exterior wall through metal brackets, which can reflect light on the one hand, and on the other hand, by increasing the thickness of the air layer between the glass curtain wall panels, it effectively reduces the conduction of heat and improves the thermal insulation performance of the building. In particular, rock wool and other linings can be added to the air layer to slow down heat transfer and facilitate building insulation, or porous sound-absorbing materials can be added to enhance the external sound insulation effect and create a comfortable low-noise environment inside the building.

[0003] The installation of glass curtain wall is to first fix the alloy frame (also known as steel structure) on the building's exterior wall through embedded parts or expansion bolts, fill it with sound insulation and heat insulation materials, apply structural adhesive to stick to the inside of the decorative glass, and then add steel structure clips or steel structure buckle covers to the side seams of the decorative glass. This installation process still has shortcomings, such as: The positioning of facing glass on the steel structure is entirely based on experience, which is prone to errors and may cause adverse effects such as skewness.

[0004] Most of the coating of structural adhesive is done on the back of the decorative glass, so the line of sight is blocked by the decorative glass, and the coating path cannot be judged, and there may be leaks or gaps. Summary of the invention

[0005] The purpose of the present invention is to provide a folded-line environmentally friendly sound-insulating and heat-insulating glass curtain wall, which can realize the gluing and glass installation operations on the outside of the steel structure frame, has a high degree of visualization throughout the process, prevents obstruction of the line of sight, and is not prone to errors, leaks or gaps.

[0006] The technical solution adopted by the present invention is as follows: A folded-line environmentally friendly sound-insulating and heat-insulating glass curtain wall, comprising: A steel structure frame, wherein the steel structure frame is divided into regularly arranged triangular cells, each of which is equipped with two mutually inclined decorative glasses, and both sides of the decorative glasses are provided with mixed glue; Alloy frames, two of which are obliquely arranged on the triangular cells for clamping the two decorative glasses, hinged arms hinged to the triangular cells and alloy grooves opening toward the decorative glasses are fixed at intervals on both sides of the alloy frames, the inner wall of the alloy groove is provided with an inner concave portion and a wedge-shaped piece fixed in the inner concave portion, the wedge-shaped piece is an open "Y" shape with both sides of the bifurcation extending in a wavy shape toward the inner wall of the inner concave portion, and the wavy interior is filled with expansion rubber; Buckle covers, two of which are respectively arranged vertically on both sides of the decorative glass, and the buckle cover parts extend into the triangular cells and are fixed with plugs; During installation, the alloy frame is turned outward to expose the alloy groove and the decorative glass is inserted, and mixed glue is injected into the concave part to stick to the decorative glass. The expansion rubber contacts the mixed glue and expands to push the wedge-shaped piece to straighten the decorative glass and pull the mixed glue. The sufficient state of gluing is judged by the wedge-shaped piece sticking to the decorative glass.

[0007] As an optional solution, the triangular unit cell includes vertical square tubes and triangular steel frames that are spaced apart, a pin shaft is provided between the triangular steel frame and the articulated arm, the inclined surface of the triangular steel frame is recessed inwardly and a movable pin fixedly connected to the alloy groove is inserted into the recess.

[0008] As an optional solution, a first leg and a first buckle ring are fixed in sequence on both sides of the triangular cell, and a second leg and a second buckle ring are fixed in sequence in the middle of the triangular cell, and the first buckle ring and the second buckle ring are both used to cover the plug.

[0009] As an optional solution, the plug is arrow-shaped and spiral ribs are fixed on both sides of the arrow shape, a wavy paper clip is fixed between the middle of the spiral rib and the tail of the arrow shape, and the spiral rib and the paper clip support the two sides of the arrow shape when they rebound.

[0010] As an optional solution, two limit blocks and a one-way bearing located in the middle of the limit blocks are spaced apart on both sides of the arrow shape of the plug, and two groups of the one-way bearings are rotatably installed on the outside of the first buckle ring and the outside of the second buckle ring respectively.

[0011] As an optional solution, a built-in glue bag for containing alloy adhesive is fixed inside the depression of the triangular steel frame, and a spike is fixed in the middle of the movable pin for piercing the built-in glue bag as the movable pin is immersed in the depression of the triangular steel frame.

[0012] As an optional solution, foam rods and structural sealant are sequentially bonded to both sides of the buckle cover, and the structural sealant adheres to the decorative glass when the buckle cover is partially inserted into the triangular unit cell.

[0013] As an optional solution, the mixed glue includes silicone weather-resistant sealant and a waterproof layer and sound-proof cotton strips respectively bonded to both sides of the silicone weather-resistant sealant, and the waterproof layer and the sound-proof cotton strips are used to close the gap between the buckle cover and the decorative glass.

[0014] As an optional solution, a thermal insulation rock wool support plate with two sides bent toward the middle is fixed to the inner wall of the triangular steel frame, and a special-shaped fastening piece is bonded in the middle of the thermal insulation rock wool support plate.

[0015] As an optional solution, adjustment rings parallel to the vertical square tubes are welded on both sides of the triangular steel frame, and fastening bolts that hold the triangular steel frame together with the vertical square tubes are inserted inside the adjustment rings.

[0016] The technical effects achieved by the present invention are: The present invention pre-installs regularly arranged triangular units on the wall to form a steel structure skeleton. Two alloy frames with double-doors that can be opened are used on these triangular units. After the alloy grooves are exposed, glue coating and glass installation operations are carried out from the outside. The whole process has a high degree of visualization to prevent obstruction of the line of sight and is not prone to errors, leaks or gaps. In this process, the "Y"-shaped bifurcation of the wedge and the wavy extension of the bifurcation can increase the area for tightening the mixed glue, and the expansion of the rubber contacts the mixed glue to push the wedge to straighten the decorative glass and hold the mixed glue. The sufficient state of gluing is determined by the wedge sticking to the decorative glass.

[0017] After the triangular unit cell of the present invention is fixed to the wall, one end of the pin shaft is rotated and inserted into the reserved hole of the hinged arm so as to realize the flipping action of the alloy frame around the pin shaft. In particular, after the facing glass is clamped, the alloy frame is reversed to cover the triangular unit cell. At this time, the movable pin is driven to be inserted into the recessed part so as to support the alloy frame along the inclined surface, thereby improving the stability of the facing glass cover on the triangular unit cell.

[0018] The present invention can compress the spiral ribs and the paper clips on both sides of the arrow-shaped plug, and completely immerse them in the triangular unit cell, and then release them from the compressed state, so that the spiral ribs and the paper clips support the two sides of the arrow shape when they rebound, which not only strengthens the structural strength of the connection between the buckle cover and the triangular unit cell, but also facilitates the rapid rebound of the plug to enter the open state and quickly tighten with the triangular unit cell.

DETAILED DESCRIPTION

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0022] like Figure 1-Figure 10 As shown, a folded-line environmentally friendly sound-proof and heat-insulating glass curtain wall includes a steel structure skeleton, an alloy frame 1, and a buckle cover 2. The steel structure skeleton is divided into regularly arranged triangular cells, such as horizontal and vertical matrix arrangements. Each triangular cell is installed with two mutually inclined decorative glasses, and mixed glue is provided on both sides of the decorative glasses. During installation, the alloy frame 1 is flipped outward along the horizontal plane to expose it, and the mixed glue is applied to the outside of the triangular cell and the decorative glass is inserted. After the installation is completed, the alloy frame 1 is reversed to cover the triangular cell, and the buckle cover 2 is inserted into the vertical gap of the triangular cell to press the decorative glass, so as to realize the gluing and glass installation operations on the outside of the steel structure skeleton. The whole process has a high degree of visualization, which prevents obstruction of the line of sight and is not prone to errors, leaks or gaps.

[0023] In view of the complex noise in the city, the selection of decorative glass needs to be cautious. It is mainly made by injecting a certain interval of air or gas between two pieces of glass to form a hollow layer, and then glued with polyurethane tape in the factory. According to the construction drawings, these double-layer glass substrates are cut into squares of specified sizes for use. After being installed in the triangular unit, the hollow layer can be used for sound insulation and noise reduction.

[0024] See attached Figure 1 , Figure 3 and Figure 4 In order to realize the folding-shaped setting of the decorative glass, two alloy frames 1 are tiltedly set in the triangular unit cell for clamping two pieces of decorative glass, and hinged arms 101 hinged to the triangular unit cell and alloy grooves 102 opened toward the decorative glass are welded at intervals on both sides of the alloy frame 1. The hinged arms 101 are used to support the alloy frame 1 at the position of the triangular unit cell close to the wall, so that the two alloy frames 1 of each triangular unit cell can be opened in a double-door style. After opening, glue can be applied to the outside of the triangular unit cell and decorative glass can be installed. Among them, in order to firmly bond the mixed glue, the inner wall of the alloy groove 102 is provided with an inner recess 103 and a wedge 104 welded in the inner recess 103 in this embodiment, so that the inner recess 103 and the wedge 104 can straighten the decorative glass and hold the mixed glue.

[0025] Furthermore, the wedge 104 is bifurcated in a "Y" shape, and the two sides of the bifurcated part extend in a wave shape deep into the inner concave part 103, which can increase the area for tightening the mixed glue, and when inserting the decorative glass, the deformation of the bifurcated part and the wave shape is used for buffering, and the mixed glue is continuously tightened. At the same time, the wave shape is filled with expansion rubber 105, so that the expansion rubber 105 contacts the mixed glue and expands to push the wedge 104 to straighten the decorative glass and pull the mixed glue. The glue application is sufficient by visually observing that the wedge 104 is attached to the decorative glass, otherwise the glue application continues; Furthermore, in the present embodiment, the expansion rubber 105 may be made of EPDM (ethylene-propylene diene copolymer) based water-swellable elastomer, which expands more than twice in volume after encountering the mixed rubber, which not only enhances its sealing effect but also provides additional cushioning and protection. It is particularly suitable for pushing the two sides of the "Y"-shaped bifurcation of the wedge 104 to bend toward the decorative glass to achieve clamping. In other embodiments, it may be replaced by materials such as fiber-sponge solid belt wire, which has a good expansion coefficient.

[0026] See attached Figure 2 , Figure 3 and Figure 4The steel structure skeleton can be pre-produced and processed in a modular factory, especially suitable for the folded glass curtain wall. The triangular unit cell of this embodiment includes vertical square tubes 3 and triangular steel frames 4 distributed at intervals. After these vertical square tubes 3 are installed on the wall through embedded parts or expansion screws, they are vertically connected. The connection can be reinforced with fasteners such as clamps, and the triangular steel frame 4 is fixed with thumb screws, etc., and a pin shaft 5 is provided between the triangular steel frame 4 and the hinge arm 101. One end of the pin shaft 5 is rotated and inserted into the reserved hole of the hinge arm 101 so as to realize the flipping action of the alloy frame 1 around the pin shaft 5. In particular, after the facing glass is clamped, the alloy frame 1 is reversed to cover the triangular unit cell. At this time, the triangular steel frame 4 is designed to be recessed inwardly on the inclined surface and a movable pin 6 welded to the alloy groove 102 is inserted in the recess, which drives the movable pin 6 to be inserted into the recess so as to support the alloy frame 1 along the inclined surface and improve the stability of the facing glass cover on the triangular unit cell.

[0027] See attached Figure 3 and Figure 4 When the movable pin 6 is inserted into the recess, it has a certain degree of freedom and needs to be further reinforced. In this embodiment, a built-in glue bag 601 for containing alloy adhesive is bonded to the inside of the recess of the triangular steel frame 4 in advance in the factory. The built-in glue bag 601 is relatively thin and will break when poked. A spike 602 is welded in the middle of the movable pin 6 to puncture the built-in glue bag 601 as it is immersed in the recess of the triangular steel frame 4. In this way, the movable pin 6 is linked with the spike 602 to puncture the built-in glue bag 601, so that the alloy adhesive automatically flows out, and the movable pin 6 is bonded to the recess, so that the triangular steel frame 4 and the alloy groove 102 are quickly tightened, and no additional bonding operation is required.

[0028] See attached Figure 2 , Figure 3 and Figure 5 During the installation of the triangular steel frame 4, in this embodiment, adjustment rings 16 parallel to the vertical tube 3 are welded on both sides of the triangular steel frame 4. The adjustment rings 16 are placed close to the outer side of the vertical tube 3 to adjust the distance between the triangular steel frame 4 and the wall. Then, the fastening bolts 17 that pull the triangular steel frame 4 with the vertical tube 3 are inserted inside the adjusting rings 16 to fasten the triangular steel frame 4, thereby fixing the triangular steel frame 4 to the vertical tube 3.

[0029] A triangular hollow layer is left between the folding glass curtain wall and the wall surface, which allows air to circulate. However, the heat insulation performance of this air is low and needs to be further strengthened. If the insulation material is laid directly, it will be blocked by the steel structure frame, and the bonding strength is poor, and it is easy to fall off under the impact of strong wind.

[0030] See attached Figure 2 and Fig.10In this embodiment, a thermal insulation rock wool support plate 14 with two sides bent toward the middle is fixed to the inner wall of the triangular steel frame 4 by screws. The thermal insulation rock wool support plate 14 has two sides bent toward the middle and can be modularly prefabricated in the factory to clamp the inner edge of the thermal insulation rock wool board layer to achieve rapid positioning and clamping, and a special-shaped fastening piece 15 is bonded in the middle of the thermal insulation rock wool support plate 14. The fastening piece 15 is made of polyurethane material and can be pressed against the thermal insulation rock wool board layer outward during elastic deformation to increase the friction between the thermal insulation rock wool board layer and the thermal insulation rock wool support plate 14, so that the fixation is more secure.

[0031] See attached Figure 1 , Figure 2 and Figure 4 Glass curtain walls are often exposed to outdoor environments, facing direct sunlight, air flow impact, rain washing, etc. The mixed glue of this embodiment includes silicone weather-resistant sealant 11 and a waterproof layer 12 and sound insulation strips 13 respectively bonded to both sides of the silicone weather-resistant sealant 11. The silicone weather-resistant sealant 11 is used to firmly bond the facing glass to the inside of the alloy frame 1, and the waterproof layer 12 of any material selected from chloroprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, and polyisobutylene is provided on the outside of the silicone weather-resistant sealant 11 to protect against wind and rain. The waterproof layer 12 and the sound insulation strips 13 are both used to seal the gap between the buckle cover 2 and the facing glass, and the sound insulation strips 13 are elastically deformed by themselves and can be well filled in the facing glass interlayer.

[0032] The zigzag glass curtain wall has several triangular bends, including concave grooves and convex ridges. Both the glass seams at the grooves and the glass seams at the ridges require additional sealing measures. However, the structural strength of directly applying glass glue is not high, and the glass glue is easily mechanically damaged by the vibration of the triangular cells, resulting in risks such as cracking and debonding.

[0033] See attached Figure 1 , Figure 6 and Figure 7 For the glass seams at the groove and the ridge, this embodiment uses two buckle covers 2 which are vertically arranged on both sides of the decorative glass. One of the buckle covers 2 in a "Y" shape is used to insert into the glass seam at the groove, and the other arrow-shaped buckle cover 2 is used to insert into the glass seam at the ridge, so that the two sides of the buckle cover 2 can be conveniently attached to the adjacent decorative glass. The buckle cover 2 is designed to partially extend into the triangular cell and partially welded with a plug 201. The plug 201 is used to tightly insert the triangular cell so as to securely pull the buckle cover 2, and there will be no risk of cracking due to the vibration of the triangular cell caused by wind.

[0034] See attached Figure 6 and Figure 7The side seams of the buckle cover 2 still need to be sealed. In this embodiment, foam rods 9 and structural sealants 10 are sequentially bonded on both sides of the buckle cover 2. The structural sealants 10 are used to bond the side seams to prevent them from being torn apart. The structural sealants 10 are also used to stick to the decorative glass when the buckle cover 2 is partially inserted into the triangular cells to further reinforce the decorative glass. The foam rods 9 can provide sound insulation while structurally supporting the structural sealants 10 to prevent unnecessary skewing, lack of glue, and the like of the structural sealants 10.

[0035] See attached Figure 6 , Figure 7 and Figure 8 In order to tighten the plug 201, in this embodiment, the first leg 203 and the first buckle ring 202 are welded in sequence on both sides of the triangular unit cell, and the second leg 205 and the second buckle ring 204 are welded in sequence in the middle of the triangular unit cell. The first buckle ring 202 and the second buckle ring 204 are both used to cover the plug 201, so that the two sides of the plug 201 can enter the first buckle ring 202 or the second buckle ring 204 after bending inward, and then rebound to hook the first buckle ring 202 or the second buckle ring 204 to prevent falling off, and the plug is fixed to the triangular unit cell by tightening the first leg 203 and the second leg 205.

[0036] See attached Figure 6 , Figure 7 and Fig. 9 Since the plug 201 is in the shape of an arrow, the structures on both sides are relatively low and can be easily broken. Therefore, in this embodiment, spiral ribs 206 are welded on both sides of the arrow, and a wavy paper clip 207 is welded between the middle of the spiral rib 206 and the tail of the arrow. When the plug 201 enters the first buckle ring 202 or the second buckle ring 204, the spiral rib 206 and the paper clip 207 can be compressed, and the entire plug 201 is immersed in the triangular unit cell, and then it is released from the compressed state. When the spiral rib 206 and the paper clip 207 rebound, they support the two sides of the arrow, which not only strengthens the structural strength of the connection between the buckle cover 2 and the triangular unit cell, but also facilitates the rapid rebound of the plug 201, enters the open state, and is quickly tightened with the triangular unit cell.

[0037] See attached Figure 6 , Figure 7 and Fig. 9 Two limit blocks 7 and a one-way bearing 8 located in the middle of the limit blocks 7 are arranged at intervals on both sides of the arrow shape of the plug 201. The one-way bearing 8 is used to limit the one-way rotation of the limit block 7, so that the plug 201 can only push the limit block 7 to rotate around the one-way bearing 8 when entering the triangular cell, and the plug 201 cannot push the limit block 7 when it wants to retreat, thereby achieving a limited state. The two sets of one-way bearings 8 are rotatably installed on the outside of the first buckle 202 and the outside of the second buckle 204, respectively, which can be closer to the arrow-shaped plug 201 and prevent the plug 201 from breaking free.

[0038] The working principle of the present invention is: during installation, the vertical tube 3 is installed on the wall through embedded parts or expansion screws, connected vertically, and the distance between the triangular steel frame 4 and the wall is adjusted, and the triangular steel frame 4 is fixed to the vertical tube 3 by tightening bolts 17.

[0039] First, the alloy frame 1 is rotated forward around the pin shaft 5 and the hinged arm 101, so that the two alloy frames 1 of each triangular unit cell can be opened in a double-door style, and the alloy groove 102 is exposed after opening, and glue can be applied and decorative glass can be installed on the outside of the triangular unit cell, and the inner recess 103 and the wedge-shaped piece 104 can be used to straighten the decorative glass and hold the mixed glue.

[0040] The alloy frame 1 is then reversed to drive the decorative glass to cover the triangular unit cell. At this time, the movable pin 6 is linked to the spike 602 to puncture the built-in glue bag 601, so that the alloy adhesive automatically flows out, and the movable pin 6 is bonded to the recessed position, so as to achieve rapid tightening of the triangular steel frame 4 and the alloy groove 102.

[0041] Subsequently, the two sides of the plug 201 bend inward to enter the first buckle ring 202 or the second buckle ring 204, and then rebound to hook the first buckle ring 202 or the second buckle ring 204 to prevent falling off, and are fixed in the triangular unit cell by tightening the first leg 203 and the second leg 205.

[0042] When the plug 201 enters the first buckle ring 202 or the second buckle ring 204, the spiral rib 206 and the paper clip 207 can be compressed, and the entire plug 201 is immersed in the triangular unit cell, and then it is released from the compressed state. When the spiral rib 206 and the paper clip 207 rebound, they support the two sides of the arrow shape, so that the plug 201 rebounds quickly, enters the open state, and is quickly tightened with the triangular unit cell.

[0043] The above is only an optional implementation of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified and limited.
