Description
Technical Field
[0001] The present invention relates to the technical field of curtain wall installation, and in particular to a multi-directional adjustable connection structure for a curtain wall unit and a curtain wall installation method. Background Art
[0002] In recent years, prefabricated curtain wall installation technology has continued to advance, evolving from the early on-site installation of keels and panels piecemeal to the gradual introduction of prefabrication and modularization, significantly improving construction efficiency and quality. However, existing technologies still have some shortcomings, such as poor quality of embedded components, welding processes that affect installation accuracy, and difficulty in on-site adjustments. Furthermore, for curtain wall installations in temporary buildings or complex corner structures, traditional methods struggle to adapt quickly to changing site conditions and angles. Summary of the Invention
[0003] In order to solve the above problems, the present invention provides a multi-directional adjustable connection structure for a curtain wall unit and a curtain wall installation method to solve the above problems.
[0004] A multi-directional adjustable connection structure for a curtain wall unit, comprising:
[0005] Upper mounting adjustment module: It consists of a mounting steel plate, an adjustable sliding steel piece, and a top screw sliding screw adjustment channel; the mounting steel plate is provided with oblong holes in the left and right directions and is fixed to the concrete member by embedded bolts; the top screw sliding screw adjustment channel includes an overhanging steel piece, an internal threaded sleeve, and a vertical top screw; the adjustable sliding steel piece is connected to the overhanging steel piece of the top screw sliding screw adjustment channel and is embedded in the oblong hole of the mounting steel plate;
[0006] Ground plug adjustment module: It consists of an L-shaped galvanized angle steel and a slot assembly. The L-shaped galvanized angle steel has an oblong hole for entry and exit, which is adjusted and fixed by a stainless steel screw and nut. An EPDM rubber pad is installed between the slot assembly and the ground plug.
[0007] Furthermore, the oblong hole of the hanging steel plate is slidably matched with the adjustable sliding steel part; the vertical top screw of the top screw sliding screw rod adjustment channel abuts against the concrete component; the top screw sliding screw rod adjustment channel includes a top screw and a screw thread.
[0008] Furthermore, the adjustable sliding steel parts and the top screw sliding screw adjustment channel have three-dimensional adjustability. The top screw limiter allows for in-and-out adjustment of the bolts and screws. The mounting steel plate has oblong holes in the left and right directions to achieve left-right adjustment, which can effectively absorb the deviation caused by the main structure. The multi-directionally adjustable semi-unit ground plug system includes ground plugs and slots, which serve as the plug-in connection between male and female curtain wall materials. The L-shaped galvanized angle steel has oblong holes in the entry and exit directions for adjusting the keel installation deviation, ensuring that after the aluminum panels are installed, all panels are in the same entry and exit position, achieving a smooth and beautiful facade effect.
[0009] Furthermore, the stainless steel screw passes through the threaded sleeve of the top screw sliding screw adjustment channel and is locked by a nut.
[0010] Furthermore, the extended steel part is fully welded to the U-shaped steel part, and the inner diameter of the built-in threaded sleeve is 1.5-2 mm larger than the diameter of the stainless steel screw, forming an adjustment margin.
[0011] Furthermore, the protruding steel member is embedded in the guide groove of the adjustable sliding steel member, and a locking bolt is provided on the side wall of the guide groove.
[0012] Furthermore, the protruding steel piece of the top screw sliding screw adjustment channel can be axially rotated by ±5° and is connected to the U-shaped steel piece through an arc groove.
[0013] Furthermore, the upper hook system of the half unit can be adjusted in multiple directions. The hook is made of a galvanized steel pipe, and one end of the upper U-shaped steel piece is installed with a top screw sliding screw adjustment channel. The steel piece extending from the top screw sliding screw adjustment channel is fully welded to its upper and lower parts. The connection groove includes an L-shaped galvanized angle steel, a steel washer, a nut, a stainless steel screw, and a U-shaped steel piece. The groove body is provided with an oblong hole, through which the stainless steel screw passes.
[0014] Furthermore, the semi-unit hanger directly hangs the protruding steel parts of the top screw sliding screw adjustment channel onto the stainless steel screw, and the adjustable sliding steel parts are used to adjust the level of the semi-unit; the protruding steel parts of the top screw sliding screw adjustment channel are fixed in and out with nuts on the stainless steel screw to prevent sliding in and out, and the semi-frame C-shaped steel conversion parts in the figure are fully welded to the galvanized steel pipe and connected to the vertical unit keel.
[0015] Furthermore, the ground plug is fully welded with nuts and C-shaped steel conversion parts; the slot is fully welded with steel washers and a bolt combination consisting of steel washers, nuts, and stainless steel screws. To avoid forward and backward movement, EPDM rubber pads are placed between the ground plug and the slot according to the actual size, and are fully welded to the interlayer unit keel through steel washers.
[0016] A curtain wall installation method comprises the following steps:
[0017] Step 1: Factory prefabrication; use BIM technology to model and generate the positioning coordinates of embedded parts, including embedded steel plates, embedded bolts, etc., unit size and angle parameters;
[0018] In the factory, the keel, including galvanized steel pipes and C-steel conversion parts, is assembled with the curtain wall aluminum panels into independent units, and the insulation layer is integrated. The key connection points are fastened with bolts or fully welded to avoid on-site welding deformation. At the same time, the center of gravity of each unit is calculated, and the lifting points are marked on the skeleton entity to reduce lifting swing.
[0019] Step 2: On-site hoisting and adjustment; perform gravity analysis on the unit and mark the center of gravity as the hoisting point to reduce hoisting swing;
[0020] Hooking system, three-dimensional adjustment;
[0021] Left and right adjustment: The long round hole is opened in the hanging steel plate, and the unit is moved horizontally through the stainless steel screw.
[0022] In and out adjustment: The top screw slides the screw rod to adjust the channel and cooperates with the nut to fix the front and rear position of the unit.
[0023] Up and down adjustment: The height of the U-shaped steel parts and the galvanized steel pipe is adjusted by the top screw limiter.
[0024] Underground plug-in system for a secure connection;
[0025] The plane deviation between the ground plug and the slot is adjusted through the oblong hole of the L-shaped galvanized angle steel, and an EPDM rubber pad is placed in the middle to ensure that the facade is flat after all units are installed.
[0026] Step 3: Precision control; after hoisting, scan the unit settlement and deformation data, compare with the BIM model to correct errors, and guide the precise cutting of non-standard aluminum plates to reduce waste.
[0027] Step 4: Finishing process: install the insulation layer, splice and seal the curtain wall aluminum panels to complete the construction.
[0028] Compared with existing technologies, this invention offers the following advantages: By prefabricating curtain wall units in the factory, the keel and panels are assembled and then transported to the site for hoisting, significantly reducing on-site construction processes and time. This prefabrication method not only improves installation accuracy but also optimizes the construction process, enabling multiple processes to be carried out in parallel, significantly shortening the construction period.
[0029] The use of a multi-directional adjustment device allows for more flexible and precise horizontal, vertical, and angular adjustment of curtain wall units, further improving construction quality. Factory prefabrication reduces on-site material stacking and loss, lowering safety risks. Furthermore, the construction process is more environmentally friendly, reducing noise and dust pollution. This invention also facilitates subsequent maintenance; if problems arise, simply replace the corresponding component. BRIEF DESCRIPTION OF THE DRAWINGS
