This ensures reasonable stress distribution on the curtain wall unit in its ultra-long state after verticalization and facilitates the easy removal of the auxiliary installation frame. The reinforcing plate enhances the overall rigidity and integrity of the installed curtain wall unit during use.

Description

Technical Field

[0001] This invention relates to the field of glass curtain wall installation technology, and in particular to a construction method for an ultra-long glass curtain wall unit installation structure. Background Technology

[0002] Glass curtain walls are a common building envelope in modern architecture due to their aesthetics, energy efficiency, and safety. Typical glass curtain walls are constructed as unitized panels and installed via hoisting. Common unitized panel dimensions are generally around 1.5m wide and under 6m high, with simple beam connections. However, to achieve visual spaciousness and interior design effects, ultra-long glass curtain walls are now appearing; and when encountering multi-level areas, to ensure a unified indoor and outdoor effect, they also require design as large multi-level unitized structures. Therefore, ensuring the safe and convenient hoisting of ultra-long glass curtain walls and meeting overall rigidity requirements after installation necessitates targeted design. Summary of the Invention

[0003] This invention provides a construction method for an ultra-long glass curtain wall unit installation structure, which solves technical problems such as the setting of auxiliary frames, convenient hoisting, and overall installation of ultra-large glass curtain wall units.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A construction method for an ultra-long glass curtain wall unit installation structure, wherein the glass curtain wall is an ultra-long glass curtain wall with a length of not less than 10m, and the specific steps are as follows: Step 1: The curtain wall unit to be installed includes a glass curtain wall and a main frame set on the glass curtain wall. The main frame is composed of column assemblies, connecting assemblies and beams connected to the column assemblies. The column assembly includes a main column and a reinforcing plate set inside the main column. The joint between adjacent curtain wall units is provided with a first main column and a corresponding second main column; both the first and second main columns are fitted with reinforcing plates. Step 2: Fabricate auxiliary mounting brackets according to the dimensions of the curtain wall units, wherein the length and width of the auxiliary mounting brackets shall not be less than the length and width of the glass curtain wall; Step 3: When making the auxiliary installation frame, a bottom stop should be installed at least at one end along the longitudinal direction, and side stops should be installed at intervals along the longitudinal direction; the installation of the bottom stop and side stops will ensure that the curtain wall unit does not slip during hoisting. Step 4: After the auxiliary mounting bracket is fabricated, place the curtain wall unit with the main frame installed on top of it; set the first suspension point on the auxiliary mounting bracket, with the first suspension point located at the opposite end of the bottom support; set the second suspension point on the glass curtain wall, with the second suspension point also located at the opposite end of the bottom support. Step 5: During hoisting, the first hook first lifts the auxiliary installation frame, slowly lifting and moving the curtain wall unit to a near-vertical position. Then, the second hook begins to lift and bear the force, making the curtain wall unit stand upright and stable in the air. After stabilization, the first hook begins to slowly lower, and the auxiliary installation frame slowly falls to the ground. The first hook is removed, and the curtain wall unit is lifted to the installation position using the second hook. Step Six: The column components of the curtain wall unit are connected to the main structure by a docking component. Connecting brackets are pre-embedded on the main structure, and the connecting brackets are adjustable to the docking components. The first and second parent columns of adjacent curtain wall units are connected by plugging in. The joints between adjacent curtain wall units are filled with sealant, thus completing the construction of the ultra-long glass curtain wall unit installation structure.

[0005] Furthermore, the connecting bracket is an L-shaped piece with an elongated hole on its horizontal part, through which it is connected to the main structure by bolts; the vertical part of the connecting bracket is connected to the docking assembly. The docking components are provided in at least two sets. Each set of docking components includes a first docking piece and a second docking piece. The first docking piece is an L-shaped piece, and the second docking piece is a U-shaped piece with a vertical connecting plate. The U-shaped opening is connected to the horizontal part of the first docking piece, and the vertical connecting plate is connected to the vertical column.

[0006] Furthermore, both the first and second vertical pillars are provided with cavities, and an insert plate is provided on one side of the first vertical pillar, while the second vertical pillar is provided with a notch corresponding to the insert plate; a reinforcing plate is inserted into the cavity.

[0007] Furthermore, the reinforcing plate is a rigid plate with strength adapted to resist the bending strength of the glass curtain wall, and the reinforcing plate is usually installed within the height range of the glass curtain wall; the reinforcing plate is connected to the corresponding vertical column by screws and bolts.

[0008] Furthermore, the reinforcing plate includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is inserted into the cavity of the first vertical column, and the second reinforcing plate is inserted into the cavity of the second vertical column. The first and second reinforcing plates are connected to the corresponding columns and docking components by bolts on the side of the first and second reinforcing plates adjacent to the main structure. One end of the first and second reinforcing plates is also connected to the corresponding vertical column by screws.

[0009] Furthermore, the auxiliary mounting bracket includes an auxiliary frame body, a bottom stop provided in the width direction of the auxiliary frame body, and a side stop provided in the length direction of the auxiliary frame body; the bottom stop is usually provided in the width direction of the auxiliary frame body, and the bottom stop is an L-shaped part, with its horizontal part detachably connected to the auxiliary frame body.

[0010] Furthermore, the side blocks are spaced apart along the length of the auxiliary frame, and the side blocks are detachably connected to the auxiliary frame; the height of the side blocks and the bottom blocks is not less than the thickness of the curtain wall unit, and the side blocks and the bottom blocks are also provided with a buffer pad or shock-absorbing pad on the side adjacent to the curtain wall unit.

[0011] Furthermore, the auxiliary frame includes parallel main frames and secondary frames connected between the two main frames and spaced apart; wherein, the secondary frames are connected to both ends of the main frames, and a bottom stop is connected to one end of the secondary frame; the width of the secondary frame is not less than the width of the curtain wall unit; A frame extension rod is also installed on the side of the main frame away from the bottom support. The sum of the lengths of the main frame and the frame extension rod is greater than the length of the curtain wall unit.

[0012] Furthermore, the auxiliary frame is also a frame component, which is formed by setting frame columns and frame bottom frames below the two main frames, with the bottom frames corresponding to the main frames and secondary frames; the application of frame components ensures that the rigidity and strength of the frame meet the design requirements when the curtain wall is too long during construction.

[0013] The beneficial effects of this invention are reflected in: 1) The present invention ensures that the ultra-long glass curtain wall unit does not bend during hoisting by setting up an auxiliary installation frame, and the setting of bottom and side baffles helps to ensure that the ultra-long glass curtain wall unit moves together with the auxiliary installation frame during hoisting without lateral or bottom misalignment. 2) The present invention uses a double lifting point and double hook setup, which facilitates the lifting of the auxiliary installation frame in the early stage and the lifting of the glass curtain wall unit together. In the middle stage, the curtain wall unit is lifted separately to make it vertical and then removed from the auxiliary installation frame. This not only ensures the reasonable stress of the curtain wall unit in the ultra-long state after it is vertical, but also facilitates the convenient removal of the auxiliary installation frame. 3) By setting up reinforcing plates, this invention helps to improve the overall rigidity and integrity of the curtain wall unit during use after installation; Therefore, this application solves the technical problems of auxiliary frame setting, convenient hoisting, and overall installation of ultra-large glass curtain wall units. Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention; the main objectives and other advantages of the invention can be realized and obtained by means of the methods particularly pointed out in the description.
