Description

Technical Field

[0001] The invention relates to the technical field of thermal-break aluminum curtain walls, and in particular to a structure and an installation method for improving the performance of thermal-break aluminum curtain walls. Background Art

[0002] Thermal break aluminum generally includes an outer frame and an inner frame that are relatively spaced apart. The two frames are connected into an integrated structure through heat insulation parts such as hard plastic. The heat insulation parts play the role of stable connection and heat insulation. Thermal break aluminum is arranged vertically and horizontally to form a frame structure, and at the same time, it is combined with vacuum glass or exterior wall panels to form a curtain wall, which plays the role of decoration, protection, heat preservation and sound insulation.

[0003] When a fire occurs on the inside of the curtain wall, the inner frame heats up quickly, while the thermal insulation blocks the heat, causing the outer frame to heat up more slowly and be unable to quickly dissipate heat to the outside, causing the inner frame and thermal insulation to be damaged by high temperature. Generally, the melting point of thermal insulation is much lower than that of aluminum profiles. After the thermal insulation melts at high temperature or its performance is greatly reduced, it loses its function of stable connection, and the strong stable connection between the inner frame and the outer frame is lost, making it prone to risks of shaking and falling off. The glass is also more likely to fall off, posing a huge safety hazard.

[0004] In the prior art, fire causes the thermal insulation components to melt at high temperatures, increasing the risk of curtain wall damage and falling off, posing a huge safety hazard that needs to be addressed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a structure and installation method for improving the performance of thermally insulated aluminum curtain walls in response to the above-mentioned technical deficiencies. The structure and installation method solve the problem in the prior art that fire causes high-temperature melting of thermal insulation components, increases the risk of curtain wall damage and falling off, and poses a huge safety hazard.

[0006] The technical solution adopted by the present invention is: to provide a structure for improving the performance of the thermally-broken aluminum curtain wall, comprising an outer frame and an inner frame arranged opposite to each other, wherein the outer frame and the inner frame are connected by a heat insulating member; and further comprising: There are two heat-conducting members, the two heat-conducting members are respectively arranged on the outer frame and the inner frame, and are located between the outer frame and the inner frame, there is a gap between the opposite end surfaces of the two heat-conducting members, and the upper side of the circumferential side surface of the heat-conducting member has a vertically arranged connecting column; The heat-insulating sleeve has two sides respectively sleeved on the two heat-conducting parts, the middle of the heat-insulating sleeve separates the two heat-conducting parts, the side of the heat-insulating sleeve has two support sleeves, the two support sleeves are respectively sleeved on the two connecting columns, and the melting point of the heat-insulating sleeve is lower than the melting point of the heat-insulating part; The heat conducting plate is lifted and lowered on the connecting column, the heat conducting plate has two limiting holes, the two connecting columns are respectively in the two limiting holes, the supporting sleeve is between the connecting column and the limiting holes, the lower part of the heat conducting plate abuts against the outer side of the heat insulating sleeve, when the high temperature causes the heat insulating sleeve to melt, the heat conducting plate descends and transfers heat with the heat conducting parts on both sides.

[0007] To further optimize the technical solution, the diameter of the connecting column gradually increases from the upper part to the lower part, and when the heat conducting plate descends, the limiting hole sleeve is fixed on the lower part of the connecting column.

[0008] To further optimize the technical solution, the upper portion of the heat conducting plate is an arc-shaped structure, and the heat conducting plate has a raised portion in the middle portion in the axial direction, and the raised portion is used to be inserted between the opposite end surfaces of the two heat conducting members after the heat conducting plate is lowered.

[0009] To further optimize the technical solution, the side of the support sleeve is provided with an escape opening, the escape opening passes through the heat insulation sleeve, and the connecting column passes through the escape opening and enters into the support sleeve.

[0010] To further optimize the technical solution, the two heat conducting members are detachably connected to the outer frame and the inner frame respectively.

[0011] Further optimization of this technical solution also includes: A heat-conducting block is inserted into the outer frame and the inner frame, a threaded hole is provided in the middle of the heat-conducting block, a threaded portion connected to the threaded hole is provided on one side of the heat-conducting component, and the threaded portion passes through the inner side of the outer frame or the inner side of the inner frame and is threadedly connected to the threaded hole.

[0012] Further optimizing the technical solution, the heat conducting member is a tubular structure, when the heat insulating sleeve is melted, the two heat conducting members are coaxially connected, the outer side of the outer frame and the outer side of the inner frame are provided with a plug hole, and the position of the plug hole is opposite to the heat conducting member; further comprising: A sealing plug is inserted and sealed in the insertion hole, and the end of the threaded portion abuts against the sealing plug to fix the sealing plug. The melting point of the sealing plug is lower than the melting point of the thermal insulation component.

[0013] To further optimize the technical solution, the two relatively arranged heat-conducting parts form a group of protective components, and a plurality of groups of the protective components are arranged between the outer frame and the inner frame.

[0014] A method for installing a thermally-broken aluminum curtain wall is also proposed, which uses a structure for improving the performance of the thermally-broken aluminum curtain wall, and the outer frame and the inner frame are installed into a thermally-broken aluminum frame.

[0015] The beneficial effects of the present invention are: 1. During installation, the two heat-conducting parts are blocked by the heat-insulating sleeve to reduce heat transfer. The heat-conducting plate connects the two connecting columns to strengthen the connection strength between the outer frame and the inner frame and improve stability.

[0016] 2. When a fire occurs, the melting point of the insulation sleeve is lower than that of the insulation component. The insulation sleeve melts, and the heat conducting plate descends and fits with the two heat conducting components to conduct heat, which can transfer heat to the outside faster and reduce heat accumulation, which is beneficial to prolong the durability of the insulation component in a fire and improve safety.

[0017] 3. After the heat conduction plate is lowered, the through-hole limiter sleeves are set on the connecting columns on both sides to connect the outer frame and the inner frame. Even if the heat insulation is damaged by high temperature, the outer frame and the inner frame can be connected together relatively stably to avoid complete disconnection and falling off, thereby improving safety. The connecting column can also conduct heat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] like Figure 1-8 As shown, a structure for improving the performance of a thermally-broken aluminum curtain wall comprises an outer frame and an inner frame which are arranged opposite to each other, and the outer frame and the inner frame are connected by a heat insulating member; further comprising: a heat conducting member, comprising two heat conducting members, which are respectively arranged on the outer frame and the inner frame and are located between the outer frame and the inner frame, and there is a gap between the opposite end faces of the two heat conducting members, and a vertically arranged connecting column is provided on the upper side of the circumferential side surface of the heat conducting member; a heat insulating sleeve, which is respectively sleeved on the two heat conducting members on both sides, and the middle part of the heat insulating sleeve separates the two heat conducting members, and the side surface of the heat insulating sleeve has two supporting sleeves, and the two supporting sleeves are respectively sleeved on the two connecting columns, and the melting point of the heat insulating sleeve is lower than the melting point of the heat insulating member; a heat conducting plate, which is arranged on the connecting column for lifting and lowering, and the heat conducting plate has two limiting holes, and the two connecting columns are respectively in the two limiting holes, and the supporting sleeve is between the connecting column and the limiting hole, and the lower part of the heat conducting plate abuts against the outer side of the heat insulating sleeve, and when the high temperature causes the heat insulating sleeve to melt, the heat conducting plate descends and transfers heat with the heat conducting members on both sides. The two heat-conducting parts arranged opposite to each other form a group of protection components, and a plurality of groups of protection components are arranged between the outer frame and the inner frame.

[0024] When using, Figure 1 As shown, under normal conditions, the two heat-conducting parts are fixedly connected to the outer frame and the inner frame respectively, and are located between the two. The two sides of the insulation sleeve are sleeved on the two heat-conducting parts, and the cross-section is "H"-shaped. The two heat-conducting parts are separated from each other in the middle to reduce temperature transfer. At the same time, the support sleeves on the side of the insulation sleeve are sleeved on the periphery of the two connecting columns to separate the heat conduction between the connecting columns and the inner wall of the limiting hole of the heat-conducting plate. The insulation sleeve also blocks the heat conduction between the heat-conducting plate and the heat-conducting parts.

[0025] When Figure 5 As shown, when a serious fire occurs, the indoor temperature rises rapidly, or the flames heat the inner frame, the inner frame and the heat-conducting parts heat up rapidly, and the heat-insulating sleeve has a lower melting point than the heat-insulating parts. Before the heat-insulating parts are seriously damaged and fail, the heat-insulating sleeve (including the support sleeve) melts, and the heat-conducting parts can transfer heat through thermal radiation. The heat-conducting plate descends, and the heat-conducting plate directly contacts the two heat-conducting parts to transfer heat, accelerate the transfer of heat to the outside, play a cooling role, and extend the service life of the heat-insulating parts. The limit holes are still set outside the connecting column, and the relative displacement between the inner frame and the outer frame is limited. Even after the heat-insulating parts melt or fail, the outer frame and the inner frame will not directly separate. After the two heat-conducting parts and the heat-conducting plate establish heat transfer between the outer frame and the inner frame, when the fire department sprays water to cool down the outer periphery of the curtain wall, it can also be transferred to the inner frame faster, protecting the heat-insulating parts and the inner frame, and extending the maintenance time.

[0026] The upper part of the heat conducting plate is arc-shaped and fits the heat conducting part, which can be fitted for heat conduction. The lower part of the heat conducting plate can be a snap-on structure, which is clamped on both sides of the heat insulating sleeve to make the heat conducting plate more stable and prevent it from loosening and falling off. At the same time, the weight of the heat conducting plate is increased. When the heat insulating sleeve melts, the heat conducting plate can drop under its own weight. Even if the heat conducting plate fails to drop in time, the heat conducting plate can still transfer heat well with the heat conducting part through the connecting column, and both the connecting column and the heat conducting part can be made of materials with good thermal conductivity.

[0027] The early melting of the insulation sleeve can be used in severe fire situations before the insulation components are damaged, thus avoiding secondary hazards such as rapid falling of the curtain wall or glass, improving safety, and partially replacing the curtain wall after the disaster to maintain the original insulation effect, which is of practical significance.

[0028] Furthermore, the diameter of the connecting column increases gradually from the upper part to the lower part, and when the heat conducting plate descends, the limiting hole sleeve is fixed on the lower part of the connecting column.

[0029] When using, Figure 5 As shown, the connecting column can be a conical or truncated cone-shaped structure that is narrow at the top and wide at the bottom. The support sleeve can be adapted to the connecting column structure. The inner diameter of the limiting hole is equivalent to the diameter of the lower part of the connecting column. Under normal circumstances, the support sleeve blocks the connecting column and the inner wall of the limiting hole. After the insulation sleeve melts, the heat conducting plate descends and slides down the limiting hole to the bottom of the connecting column. The fixed sleeve is arranged on the connecting column with a small gap to achieve a more stable connection, reduce the relative displacement that may occur between the two heat conducting parts, and improve the stability of the inner frame and the outer frame. Even if the insulation sleeve cannot completely flow downward and disappear after melting, good heat conduction can be established between the heat conducting plate and the heat conducting part. The insulation sleeve can preferably be made of a heat-insulating polymer material with a lower melting point than the insulation part and good fluidity after melting.

[0030] Furthermore, the upper part of the heat conducting plate is an arc-shaped structure, and the heat conducting plate has a protrusion in the middle part in the axial direction, and the protrusion is used to be inserted between the opposite end surfaces of the two heat conducting parts after the heat conducting plate descends.

[0031] When in use, the upper part of the heat conducting plate can be a semicircular arc structure, and the heat conducting member is a circular structure. The inner wall of the upper part of the heat conducting plate can better fit or be close to the heat conducting member to achieve better heat conduction. The raised portion can be distributed along the arc. When the heat conducting plate is lowered, the heat conducting plate as a whole abuts against the heat conducting member, and the raised portion is inserted between the two heat conducting members to enhance the heat conduction between the two. The raised portion can be chamfered to facilitate entry between the two heat conducting members. At the same time, the two heat conducting members can also be chamfered or inclined to match the raised portion, making it easier to achieve abutment between the raised portion and the heat conducting member. Those skilled in the art can select a suitable adaptation structure.

[0032] Furthermore, a side of the support sleeve is provided with an escape opening, the escape opening passes through the heat insulation sleeve, and the connecting column passes through the escape opening and enters the support sleeve.

[0033] When in use, the support sleeve can be a sleeve structure, which is separate from the heat insulation sleeve and sleeved on the connecting column. The support sleeve can also be an integrated structure with the heat insulation sleeve to reduce independent parts, while ensuring the heat insulation of the connecting column to avoid missing installation or spacing problems. The support sleeve and the heat insulation sleeve are integrated. When the heat insulation sleeve and the support sleeve are flexible parts, the avoidance can be opened by deformation, and it can be installed in the axial direction and sleeved on the connecting column. The avoidance is an extremely narrow gap, and it can be overlapped by a step structure to avoid leaks.

[0034] Furthermore, the two heat-conducting parts are detachably connected to the outer frame and the inner frame respectively. The heat-conducting blocks are also included. The outer frame and the inner frame are both provided with heat-conducting blocks. The heat-conducting blocks have threaded holes in the middle. One side of the heat-conducting part has a threaded portion connected to the threaded hole. The threaded portion passes through the inner side of the outer frame or the inner side of the inner frame and is threadedly connected to the threaded hole.

[0035] When in use, the outer frame and the inner frame are formed based on the broken bridge aluminum profile, so the heat conductive part adopts the detachable form of the post-installed parts. The detachable fixed connection can be achieved through the structures such as the slide slot connection, threaded connection, and screw connection. The inner and outer frames both have a square frame structure. The heat conductive block can slide in the inner square frame structure to set the installation position. Holes can be punched on the inner side of the outer frame and the inner frame. The threaded part of the heat conductive part passes through the frame and is threadedly connected to the heat conductive block to achieve heat conduction and improve the structural strength. The inner side of the outer frame and the inner frame refers to the opposite side between the two, and the outer side refers to the other side of the two, that is, the indoor side is the outer side of the inner frame, and the outdoor side is the outer side of the outer frame.

[0036] Furthermore, the heat conductive part is a tubular structure. When the heat insulating sleeve is melted, the two heat conductive parts are coaxially connected. The outside of the outer frame and the outside of the inner frame are provided with insertion holes, and the positions of the insertion holes are opposite to the heat conductive part. It also includes: a sealing plug, which is inserted and sealed in the insertion hole, and the end of the threaded part abuts against the sealing plug for fixing the sealing plug. The melting point of the sealing plug is lower than the melting point of the heat insulating part.

[0037] When in use, the heat conductor adopts a tubular structure, which can form a channel for discharging flames, reducing internal heat and air pressure accumulation, and facilitating water spraying from the outside to be poured into the curtain wall and indoors through the channel for cooling. The socket is relative to the heat conductor, and the heat conductor conducts heat. The sealing plug and the insulation sleeve are melted in advance to conduct heat outward. At the same time, the tubular structure forms a channel connecting the inside and outside to directly discharge heat and pressure, and facilitate water cooling. A stable seal can be formed between the sealing plug and the socket through the abutment of the heat conductor, and sealant can be added to improve the sealing and avoid daily leakage. A protective layer such as an aluminum plate can be added outside the sealing plug to improve the consistency of the exterior wall and improve the self-protection ability. The sealing plug melts and the thinner protective layer falls off naturally.

[0038] Melting does not limit solid objects to completely melt into liquid form due to high temperature, but includes changes in state such as damage to the shape, cracking and separation, inability to maintain the original structure, and being able to detach from the installation position. In addition to melting, vaporization can also be used if the material is suitable.

[0039] A method for installing a thermally-broken aluminum curtain wall is also proposed. A structure for improving the performance of the thermally-broken aluminum curtain wall is used, and an outer frame and an inner frame are installed to form a thermally-broken aluminum frame. The outer frame and the inner frame are first installed with heat-conducting blocks and heat-conducting parts respectively, and the heat-conducting parts are screwed into the heat-conducting blocks to achieve fixation, and then a heat-insulating sleeve is put on one of the heat-conducting parts. A avoidance opening is provided on the side of the heat-insulating sleeve, and the support sleeve can be directly inserted axially to surround the connecting column. Then the inner frame and the outer frame are relatively close to each other, so that the heat-insulating sleeve is inserted into the other heat-conducting part, and then the heat-conducting plate can be clamped with the help of a tool, and inserted from the top outside the connecting column to achieve the installation of the heat-conducting plate. The next step is to insert the heat-insulating part. The position of the heat-conducting part can be located between the two heat-insulating parts, and the installation position can also be selected according to the specific thermally-broken aluminum structure. The structure of the present application is suitable for the use of a variety of thermally-broken aluminum profiles, and the thermally-broken aluminum curtain wall or the thermally-broken aluminum door and window can be used. It is a diagrammatic introduction, and the inner frame and the outer frame are for simplified demonstration purposes and do not represent the limitation of actual application.

[0040] When the sealing plug is provided, the sealing plug can be inserted from the outside, and then the end of the heat conductive member can squeeze and fix the sealing plug to prevent the sealing plug from falling or sinking into the thermally-insulated aluminum frame.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
