Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of convex lens processing, and particularly to a connecting node structure for the column and crossbeam of a component type curtain wall. Background Art
[0002] In industrial construction projects such as transportation hubs, the conventional grid size of glass panels is difficult to meet the requirements of facade permeability. Usually, the horizontal grid size of curtain wall glass panels will adopt a width of 3m or even 4m (for example, the glass division of Ningbo Lishe Airport reaches 3.6x1.8, the second phase of Nanjing Lukou Airport has a glass division of 4x1.8, and the glass division of Shenzhen International Airport T3 is 4.5x1.5). Since the shapes of airports are mostly lofted with curved surfaces and curves, a component type glass curtain wall system is usually adopted. Therefore, the connection between columns and crossbeams is particularly important. According to the conventional practice of component type curtain walls, there are generally two methods to solve this problem:
[0003] One is to connect the column and crossbeam with an angle bracket: The connection form of using an angle bracket between the column and crossbeam is relatively common. This connection requires the crossbeam to use an open-profile section. After the crossbeam is connected and fixed to the angle bracket, it is connected to the column through bolts, and finally a cover is pressed on. This node practice is generally applicable to systems with smaller glass panels. Since the glass transfers its gravity to the crossbeam through a spacer, and because the glass gravity is close to the front end, eccentricity will cause torsion to the crossbeam. The crossbeam itself resists torsion through the angle bracket connected to the column. However, the angle bracket has an open-profile section and its anti-torsion performance is poor. Especially at the position of the glass spacer, the corresponding section of the angle bracket is a horizontal plate, and the angle bracket cannot be calculated for anti-torsion according to the overall section; therefore, the angle bracket connection is a technical pain point at this place during the safety assessment process and cannot pass, having great limitations.
[0004] The other is to connect the column and crossbeam with a spring pin or a dowel pin: The connection form of using a spring pin between the column and crossbeam was relatively common during the early construction process. Both the column and crossbeam of this connection have a closed-section. It can make better use of the section characteristics. However, during the installation and use process, the spring pin is prone to falling off or not being installed in place, resulting in the failure of the connection node. Therefore, this connection structure should not be used in high-rise and super high-rise buildings.
[0005] In summary, in order to solve the above problems, it is particularly important to design a connecting node structure for the column and crossbeam of a component type curtain wall. Summary of the Invention
[0006] The utility model designs a connecting node structure for the column and crossbeam of a component type curtain wall to solve the above problems. In this structure, the column and crossbeam are connected by a cross-shaped connector using a T-shaped stainless steel casting, and the aluminum alloy glass support and the T-shaped stainless steel casting adopt an integrated structure. The aluminum alloy glass support is used to support the gravity of the glass. At this time, the crossbeam does not support the gravity of the glass and only bears the wind load, making it applicable to large-size horizontally divided glass curtain walls, reducing the deflection deformation of the crossbeam due to gravity load, and making it easier for the crossbeam to meet the strength and stiffness force requirements.
[0007] To solve the above technical problems, the utility model provides a connecting node structure for the column and crossbeam of a component type curtain wall, which is characterized in that: it includes an aluminum alloy column, an aluminum alloy crossbeam, a T-shaped stainless steel casting, an aluminum alloy sub-frame, an aluminum alloy pressing block, an aluminum alloy glass support, and an aluminum alloy buckle cover. Aluminum alloy crossbeams are respectively connected to the left and right sides of the aluminum alloy column through T-shaped stainless steel castings. The aluminum alloy sub-frame is arranged inside one end of the opening of the aluminum alloy crossbeam and is integrally connected with it. The aluminum alloy crossbeam contacts the glass curtain wall assembly through the aluminum alloy sub-frame. An aluminum alloy buckle cover connecting piece is connected inside the aluminum alloy crossbeam through an aluminum alloy pressing block. One end of the aluminum alloy buckle cover connecting piece extends out of the aluminum alloy crossbeam and has a hook-shaped structure. Aluminum alloy glass supports are respectively arranged on the front and back sides of the T-shaped stainless steel casting and are integrally connected with it. The aluminum alloy glass supports are horizontally arranged, and one end of the aluminum alloy glass support also extends out of the aluminum alloy crossbeam. Glass curtain wall assemblies are respectively arranged on the upper and lower sides of the aluminum alloy glass support. The glass curtain wall assemblies are supported by the aluminum alloy glass support. The hook-shaped structure at one end of the aluminum alloy buckle cover connecting piece extends into the aluminum alloy buckle cover and is connected to a hook-shaped fastening structure arranged inside the aluminum alloy buckle cover. The glass curtain wall assemblies on the upper and lower sides of the aluminum alloy glass support are pressed tightly on the aluminum alloy sub-frame through the aluminum alloy buckle cover.
[0008] Furthermore: One end of the aluminum alloy column is a recessed part. The T-shaped stainless steel casting is detachably fixed inside the recessed part through a first bolt. Notches are opened on the side walls of the aluminum alloy column on the front and back sides of the recessed part. The two aluminum alloy glass supports on the front and back of the T-shaped stainless steel casting extend out of the aluminum alloy column along the notches. One end of the aluminum alloy crossbeam contacts the aluminum alloy column and is fixed on the T-shaped stainless steel casting extending out of the aluminum alloy column through a second bolt.
[0009] Still further: The glass curtain wall assembly is composed of a laminated triple-silver insulating glass curtain wall and a common glass curtain wall. The laminated triple-silver insulating glass curtain wall and the common glass curtain wall are successively connected to the aluminum alloy glass support. The aluminum alloy buckle cover contacts the laminated triple-silver insulating glass curtain wall. The common glass curtain wall contacts the aluminum alloy sub-frame.
[0010] Still further: An EPDM foot pad is arranged between the aluminum alloy buckle cover and the laminated triple-silver insulating glass curtain wall. A silicone structural sealant is arranged between the aluminum alloy sub-frame and the common glass curtain wall.
[0011] Even further: A sealant is filled between the glass curtain wall assemblies on the upper and lower sides of the aluminum alloy glass support.
[0012] After adopting the above structure, the beneficial effects of the utility model are as follows:
[0013] 1. In terms of structural force transmission, the upper cross beam does not need to bear the gravity of the glass. The gravity of the glass is directly transmitted to the column, and the force transmission path is more direct. The column bears the gravity of the glass in the axial direction, which is more beneficial.
[0014] 2. It is more convenient in construction. After simply milling the opening and installing it in place, just tighten the bolts. Neither the column nor the cross beam needs to be provided with an open-profile buckle cover, which has no impact on the appearance.
[0015] 3. The cross beam does not bear the gravity of the glass, reducing the torsion caused by eccentricity under the gravity of the glass.
[0016] 4. It is easy to inspect. Before installing the glass panel, the curtain wall columns, cross beams and adapters are all exposed and visible. It is convenient to check whether the construction is in place, avoiding safety accidents caused by construction workers cutting corners. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.
[0018] Figure 1 It is a structural schematic diagram of the present utility model.
[0019] Figure 2 It is a connection schematic diagram of an aluminum alloy column and an aluminum alloy cross beam. SPECIFIC EMBODIMENTS
[0020] Such as Figure 1 And Figure 2A connecting node structure for the column and crossbeam of a modular curtain wall is shown, which includes an aluminum alloy column 1, an aluminum alloy crossbeam 2, a T-shaped stainless steel casting 3, an aluminum alloy sub-frame 6, an aluminum alloy pressing block 7, an aluminum alloy glass support 9, and an aluminum alloy cover 10. One aluminum alloy crossbeam is connected to each side of the aluminum alloy column through a T-shaped stainless steel casting. The aluminum alloy sub-frame is arranged inside one end of the opening of the aluminum alloy crossbeam and is integrated with it. The aluminum alloy crossbeam contacts the glass curtain wall assembly through the aluminum alloy sub-frame. An aluminum alloy cover connecting piece 8 is connected inside the aluminum alloy crossbeam through an aluminum alloy pressing block. One end of the aluminum alloy cover connecting piece extends out of the aluminum alloy crossbeam and has a hook-shaped structure. One aluminum alloy glass support is arranged on each of the front and back sides of the T-shaped stainless steel casting and is integrated with it. The aluminum alloy glass support is horizontally arranged, and one end of the aluminum alloy glass support also extends out of the aluminum alloy crossbeam. One glass curtain wall assembly is arranged on each of the upper and lower sides of the aluminum alloy glass support. The glass curtain wall assembly is supported by the aluminum alloy glass support. The hook-shaped structure at one end of the aluminum alloy cover connecting piece extends into the aluminum alloy cover and is connected to a hook-shaped fastening structure arranged inside the aluminum alloy cover. The glass curtain wall assemblies on the upper and lower sides of the aluminum alloy glass support are pressed against the aluminum alloy sub-frame through the aluminum alloy cover. In the structure of the present utility model, the upper crossbeam does not need to bear the gravity of the glass during force transmission. The gravity of the glass is directly transmitted to the column, and the force transmission path is more direct. The column bears the gravity of the glass in the axial direction, which is more beneficial. Moreover, since the crossbeam does not bear the gravity of the glass, the torsion caused by the eccentricity of the crossbeam under the gravity of the glass is reduced. And this design is easy to inspect. Before installing the glass panel, the curtain wall column, crossbeam, and adapter are all exposed and visible. It is convenient to check whether the construction is in place and avoid safety accidents caused by the cutting of corners by construction workers.
[0021] As Figure 2 shown, one end of the aluminum alloy column has a recess. The T-shaped stainless steel casting is detachably fixed inside the recess through a first bolt. Notches are opened on the side walls of the aluminum alloy column on the front and back sides of the recess. The two aluminum alloy glass supports on the T-shaped stainless steel casting extend out of the aluminum alloy column along the notches. One end of the aluminum alloy crossbeam contacts the aluminum alloy column and is fixed on the T-shaped stainless steel casting extending out of the aluminum alloy column through a second bolt.
[0022] As Figure 1 shown, the glass curtain wall assembly is composed of a laminated triple-silver insulating glass curtain wall 4 and a common glass curtain wall 5. The laminated triple-silver insulating glass curtain wall and the common glass curtain wall are successively connected to the aluminum alloy glass support. The aluminum alloy cover contacts the laminated triple-silver insulating glass curtain wall. The common glass curtain wall contacts the aluminum alloy sub-frame.
[0023] As Figure 1An EPDM foot pad 11 is provided between the shown aluminum alloy buckle cover and the laminated triple-silver insulating glass curtain wall, and a silicone structural sealant 13 is provided between the aluminum alloy sub-frame and the ordinary glass curtain wall; a sealant 12 is filled between the glass curtain wall components on both the upper and lower sides of the aluminum alloy glass support.
[0024] The utility model can calculate the connection load of the T-shaped parts according to the specific grid size and gravity requirements of the glass panel, and measure the required bolt diameter and quantity for the connection of the column and beam. The vertical height of the T-shaped parts is increased according to the quantity, and the connection form remains unchanged; according to the specific size of the T-shaped parts, the profiles at the front end of the cavities of the column and beam are milled, and rivet nuts are arranged at the corresponding positions of the column and beam, and the T-shaped parts are fixedly connected to the column by bolts. After the beam is milled in place, it is pushed from back to front and the bolts are installed and fixed. One end of the T-shaped part has a round hole and the other end has a long hole, and one end of the beam is fixed and the other end can expand and contract horizontally. To release the horizontal expansion and contraction requirements generated under the change of ambient temperature. The construction of the utility model is relatively convenient. After the milling and installation are in place, only the bolts need to be tightened. There is no need to set the open-profile buckle covers on the column and beam, which has no impact on the appearance.
[0025] The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited to the above embodiments. All technical solutions within the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and retouches made without departing from the principle of the utility model should be regarded as the protection scope of the utility model.
