Description

Technical Field

[0001] This invention relates to the field of building exterior wall decoration technology, specifically to a cavity beam under-supported unitized curtain wall structure and its installation method. Background Technology

[0002] Unitized curtain walls can meet the design requirements of various complex building shapes, such as curved surfaces and broken lines, providing greater room for architectural design. Traditional suspended unitized curtain walls need to be suspended from top to bottom, but there is insufficient space for installation of unitized curtain walls on terraces, making it impossible to install unit panels by suspension. Therefore, a bottom-mounted unit installation method is adopted, with the bottom horizontal beam resting on the water tank. This connection position is set as the stress point of the curtain wall, and the top is an adjustable connection method. When a closed cavity bottom horizontal beam is used, there is enough space at the bottom of the beam to set the bottom-mounted installation slot. When the bottom horizontal beam is an open cavity horizontal beam, there is less space at the bottom of the beam to set the installation slot. The open cavity horizontal beam and the bottom horizontal beam cannot be connected and fixed.

[0003] Therefore, this invention proposes a cavity-type horizontal beam under-support unitized curtain wall structure and its installation method. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention proposes an open-cavity horizontal beam under-mounted unitized curtain wall structure and its installation method, which realizes the installation of open-cavity horizontal beam unit panels, facilitates installation, and ensures the visual effect of the curtain wall.

[0005] To achieve the above objectives, the technology of the present invention is as follows: A unitized curtain wall structure with an open-cavity horizontal beam includes a first-floor main structure, a second-floor main structure, unit panels, and a bottom horizontal beam. The bottom horizontal beam is fixedly connected to steel components on the first-floor main structure. Each unit panel consists of a glass panel, a bottom horizontal beam, columns, and a top horizontal beam. The top horizontal beam is connected to the top of the columns, and the bottom horizontal beam is connected to the bottom of the columns. The bottom end of the glass panel facing the interior is connected to the columns and the bottom horizontal beam, and the top end of the glass panel facing the interior is connected to the columns and the top horizontal beam. The bottom horizontal beam is located below the bottom horizontal beam. An aluminum alloy reinforcing material is provided at the bottom of the bottom horizontal beam near the column. The aluminum alloy reinforcing material is connected to the bottom horizontal beam by a rubber strip and is fixedly connected to the bottom horizontal beam. An aluminum connector is provided on the second-floor main structure. The aluminum connector is fixedly connected to a channel-type embedded part in the second-floor main structure. A base is fixedly connected to the bottom of the aluminum connector, and a bracket is fitted on the base. Both the base and the bracket are fixedly connected to the columns and the top horizontal beam.

[0006] Furthermore, the aluminum connector includes a connector vertical plate and a connector horizontal plate perpendicular to the connector vertical plate. The connector vertical plate is symmetrically provided with two oblong holes I and several toothed racks I. The connector horizontal plate is symmetrically provided with two oblong holes II and several toothed racks II.

[0007] Furthermore, it includes a gasket, on which a gasket rack is provided that matches the size of rack one and rack two. The vertical plate of the connector and the grooved embedded part are fixed to the grooved embedded part by bolt three passing through the gasket and the waist-shaped hole one, wherein rack one meshes with the gasket rack.

[0008] Furthermore, the base and the horizontal plate of the connector are fixed to the aluminum connector by bolts four through the washers and the waist-shaped holes two. The lower surface of the base is provided with a first insertion groove and a second insertion groove. The card seat is provided with a first insertion piece and a second insertion piece that are respectively matched in size to the first insertion groove and the second insertion groove. The base and the card seat are fixed by screw one after the first insertion piece mates with the first insertion groove and the second insertion piece mates with the second insertion groove.

[0009] Furthermore, it includes a limiting block, which includes a limiting block body, wherein the limiting block body is provided with a limiting groove; the limiting block is installed on the lower surface of the base by two screws, wherein the limiting groove is engaged with the column to prevent the unit plate from moving left and right.

[0010] Furthermore, the bottom beam includes a bottom beam body, a connecting protrusion at the center of the bottom beam body, and a connecting groove on the aluminum alloy reinforcing material that matches the size of the connecting protrusion. The aluminum alloy reinforcing material and the bottom beam are connected by the connecting protrusion and the connecting groove and by an adhesive strip. The bottom beam body is fixedly connected to the steel parts on the main structure of the floor by two bolts.

[0011] Furthermore, a water tank is provided inside the main body of the bottom beam.

[0012] Furthermore, the bottom crossbeam includes a bottom crossbeam body, and the bottom crossbeam body is provided with a receiving groove for accommodating aluminum alloy reinforcing material. The aluminum alloy reinforcing material is installed in the receiving groove and fixed to the bottom crossbeam by bolts.

[0013] This invention also proposes an installation method for an open-cavity horizontal beam under-supported unitized curtain wall structure, comprising the following steps: 1) First, the glass panels, bottom beams, columns, and top beams are assembled in the factory to obtain unit panels; 2) Install the assembled unit modules from step 1) on-site.

[0014] Furthermore, in step 1), after the unit panels are assembled, aluminum alloy reinforcing material is installed at the bottom of the bottom crossbeam near the column, and bolts are used to connect the bottom crossbeam and the aluminum alloy reinforcing material together. 2) The specific process in the steps is as follows: 2.1) First, install the aluminum connectors and the bottom beam. Use bolt three to fix the aluminum connectors to the channel-type embedded parts in the main structure of floor two. Use bolt two to connect the water tank and the bottom beam to the steel parts in the main structure of floor one. 2.2) Then place the adhesive strip on the sink and install the unit panels. Place the unit panels on top of the sink. After the unit panel position is adjusted, use a limit block and screw two to connect and fix the top position to the base. The limit block locks the column to prevent the panel from moving left and right. Finally, install the bracket and use screw one to limit the bracket's movement. The panel installation is then completed.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) The present invention sets aluminum alloy reinforcing material at the bottom of the bottom crossbeam near the column, and uses bolts to connect the bottom crossbeam and the aluminum alloy reinforcing material together. The aluminum alloy tube reinforcing material cooperates with the bottom crossbeam, which overcomes the problem that the cavity crossbeam and the bottom crossbeam cannot be connected and fixed. 2) The present invention sets a limiting block between the base and the unit plate. The limiting block is installed on the lower surface of the base by screw two. The limiting groove is engaged with the column, thereby preventing the unit plate from moving left and right. The unit plate is installed on the indoor side, the installation process is simple and the construction difficulty is reduced. 3) The bottom beam of this invention has a water trough inside. The water trough has two functions: First, the bottom beam is spliced ​​together from several bottom beam units. The water trough avoids the problem of water leakage at the connection between two adjacent bottom beam units. Second, the bottom beam sits on the water trough, so that the top connection of the unit plates can be adjusted. 4) This invention enables the installation of the cavity beam unit panels, which facilitates installation and ensures the visual effect of the curtain wall.
