Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall reinforcement, in particular to a reinforcement structure of a hidden frame curtain wall. Background Art

[0002] The building curtain wall refers to the non-load-bearing exterior wall enclosure of a building, which is usually composed of panels (glass, metal panels, stone panels, ceramic panels, etc.) and the supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.).

[0003] A building curtain wall is a decorative or exterior building envelope composed of a supporting structure and panels. It is capable of displacement relative to the main structure and does not share the loads exerted on the main structure. Curtain walls are non-load-bearing, hanging like a curtain, hence the name "suspended wall." They are lightweight, decorative wall structures commonly used in modern large and high-rise buildings. Composed of a structural frame and inlaid panels, they do not bear the loads or forces exerted by the main structure.

[0004] Glass curtain walls are heavy and fragile, making installation complex and difficult. Drilling holes for mounting brackets on peelable curtain walls is difficult. Therefore, glass curtain walls can only be bonded to brackets using adhesives. Currently, silicone structural adhesives are commonly used for bonding curtain walls. However, silicone structural adhesives generally have a 10-year warranty, while the design life of building curtain walls is generally 25 years. Expired structural adhesives and building curtain walls may pose numerous safety risks.

[0005] This method of bonding curtain walls with structural adhesive is called a concealed frame glass curtain wall. While it's strong and stable when first installed, concealed frame glass curtain walls can become vulnerable to panel detachment and adhesive aging over time. Currently, a large number of curtain walls are already installed in building structures, some of which are already beyond their service life, necessitating a solution to their structural strength issues.

[0006] At present, aging curtain walls that have been used for a long time are dangerous, and there is no better way to deal with them. Curtain walls are spliced ​​piece by piece. Generally, the aged part of the curtain wall is removed and then reinstalled. If many pieces of curtain wall structural adhesive are aged or even fall off, they generally need to be completely renovated and reinstalled. This curtain wall reinforcement method is difficult to construct, takes a long time to construct, and is costly, because it involves removing the original structural adhesive and re-bonding. The construction difficulty is more complicated than installing a new curtain wall.

[0007] Based on this, the utility model designs a reinforcement structure of a hidden frame curtain wall to solve the above problems. Utility Model Content

[0008] The purpose of the utility model is to provide a reinforcement structure for a hidden frame curtain wall, which can be installed on the existing hidden frame curtain wall installation structure to reinforce the existing aging curtain wall installation structure. It not only does not affect the original curtain wall structure, but also effectively improves the reliability of the curtain wall connection. In addition, the installation method is simple, the construction is simple, the operability is high, and the mechanical properties are good. There is no need to dismantle the original curtain wall installation structure, and it can be directly installed, which effectively extends the service life of the curtain wall and increases the safety and reliability of the structural adhesive work.

[0009] The utility model is implemented as follows: a reinforcement structure of a hidden frame curtain wall, comprising:

[0010] A sub-frame, an adhesive layer and a sealing strip, wherein the sub-frame is locked on the curtain wall frame by bolts, and the outer side of the sub-frame is tightly adhered to the curtain wall by the adhesive layer. The sub-frame is characterized by comprising: a reinforcement member, a buckle cover and a structural adhesive;

[0011] The reinforcement is a long strip of profile, the inner side wall of the reinforcement is a closed flat surface, and the outer side wall of the reinforcement is an opening. A reinforcement is provided on each of the left and right sides of the sub-frame. One side of the reinforcement is fastened to the side wall of the sub-frame by bolts, and the other side of the reinforcement is fastened to the building structure by bolts.

[0012] A buckle cover is clamped on the outer opening of the reinforcement; the buckle cover and the reinforcement form a closed cavity; the bolts locked with the sub-frame and the building structure are all inside the cavity formed by the reinforcement and the buckle cover.

[0013] The side of the reinforcement piece that is in contact with the auxiliary frame and the curtain wall frame is evenly coated with structural adhesive inwardly, and the gap between the reinforcement piece, the auxiliary frame and the curtain wall frame is fully coated with structural adhesive;

[0014] The other side wall of the reinforcement is also bonded to the curtain wall panel by means of structural adhesive.

[0015] Furthermore, structural adhesive is applied between the reinforcement member and the sub-frame.

[0016] Furthermore, the structural adhesive is a weather-resistant structural adhesive;

[0017] The thickness of the structural adhesive is the same as the thickness of the adhesive layer.

[0018] Furthermore, the building structure includes beams and columns.

[0019] Furthermore, the reinforcement is an aluminum profile, and the buckle cover is a complete aluminum cover plate.

[0020] The beneficial effects of the present invention are as follows: 1. The present invention is installed on the original sub-frame by means of a long strip of reinforcement, and the left and right sides are covered with reinforcement, which is convenient to install. Moreover, the reinforcement is mechanically connected by bolts, and the reinforcement increases the connection strength between the sub-frame and the building structure, effectively improving the overall connection strength. The previous operation method required the removal of the aged curtain wall, or even the curtain wall of the entire building. The current bonding method does not require the removal of the original curtain wall, and the operation method is simpler, and no removal is required, thus eliminating the need for removal steps.

[0021] 2. This device also directly bonds with the curtain wall through the reinforcement, so that the curtain wall frame can be bonded with the reinforcement and sub-frame over a larger area. It also assembles the curtain wall with the building structure through different supporting structures, which increases the supporting structure bearing mode and the bonding area of ​​the curtain wall. At the same time, it can be bonded at different ages, extending the service life of the structural adhesive.

[0022] 3. The reinforcement is bonded to the curtain wall frame and sub-frame with structural adhesive, which makes the connection stronger and more stable. At the same time, an isolation strip is set on the adhesive surface of the reinforcement to separate it, so that the device can use different adhesives on both sides of the isolation strip according to different building materials.

[0023] 4. The previous operation method required the removal of aging curtain walls, and even the curtain walls of the entire building had to be removed. The current bonding method does not require the removal of the original curtain walls. The operation method is simpler and no longer requires removal, which saves the demolition steps, saves construction costs, shortens the construction period, and effectively reinforces the curtain walls. The construction is simpler, and the original curtain wall structure can also be utilized to extend the original design life after the curtain wall is reinforced by this device. This device only reinforces the aging of the structural adhesive, thereby directly making up for the shortcomings of the service life of the hidden frame curtain wall, and it is not reinforced by the exposed frame. The exposed frame will be bound on the outside of the curtain wall. This device is still installed inside the hidden frame, so as not to affect the external beauty of the hidden frame curtain wall.
