DETAILED DESCRIPTION

[0057] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0058] like Figures 1 to 20 As shown, the present invention provides a method for installing a lower inward-inclined trapezoidal or parallelogram unit curtain wall, comprising the following steps:

[0059] Step 1: Arrange hanging accessories on the curtain wall unit 1 to be installed, wherein the hanging accessories include a force-bearing hanging weight 21 and a temporary hanging weight 23;

[0060] In this step, two load-bearing hanging brackets 21 are installed on the upper part of the curtain wall unit 1 to be installed, and a temporary hanging bracket 23 is installed on the lower part.

[0061] Two of the force-bearing hanging weights 21 are installed on the upper part of the curtain wall unit 1 to be installed. The load-bearing capacity of the force-bearing hanging weights 21 is based on the standard that a single force-bearing hanging weight 21 can bear the load of the entire curtain wall unit 1, so that it meets the force requirements after hoisting and installation.

[0062] A temporary hanging code 23 is provided on the upper bevel side of the lower part of the curtain wall unit 1 to be installed, which is used as a temporary hanging point;

[0063] The end plate 33 of each adapter 3 is enlarged to serve as a thin jack base;

[0064] Increase the adjustment stroke of the aluminum alloy load-bearing hanging weight 21 to a standard greater than the depth of the slot provided on the building structure, and adjust it to the bottom of the stroke before installation.

[0065] In this embodiment, the load-bearing hanging weight 21 and the temporary hanging weight 23 are both made of aluminum alloy, and the depth of the slot is +10 mm.

[0066] refer to Figure 4The force-bearing hanging weight 21 includes an adjusting bolt 211, a fixing member 212 and an adjusting weight 213. The fixing member 212 is used to fix the force-bearing hanging weight 21 on the curtain wall unit 1. The fixing member 212 is provided with a threaded hole. The adjusting bolt 211 is screwed into the threaded hole. The adjusting weight 213 and the fixing member 212 can slide up and down relatively. The bottom of the adjusting bolt 211 acts on the supporting adjusting weight 213, and the adjusting bolt 211 is supported on the adjusting weight 213 by gravity. Specifically, the fixing member 212 is provided with a sliding groove that passes through from top to bottom. The end of the adjusting weight 213 is provided with an 8-shaped terminal. When in use, the adjusting weight 213 slides in from the top of the fixing member 212. A threaded hole used in conjunction with the adjusting bolt 211 is provided on each side of the sliding groove. After the adjusting weight 213 is hung on the adapter 3, the fixing member 212 slides up and down relative to the adjusting weight 213 by rotating the adjusting bolt 211, thereby realizing the up and down adjustment of the curtain wall unit 1.

[0067] Step 2: hoisting the curtain wall unit 1 into the air through the load-bearing hanging weight 21 and the temporary hanging weight 23, and adjusting the posture in the air;

[0068] This step also includes the steps of:

[0069] 1. After the curtain wall unit 1 to be installed is processed in the factory, it is transported to the site and lifted by a lifting device 43 through a lifting pole 41 and three vertical hand chain hoists 42. The lifting points are respectively set on the lifting holes on the two force-bearing hanging brackets 21 and the temporary hanging brackets 23;

[0070] 2. The aerial posture of the curtain wall unit 1 to be installed is adjusted by the vertical hand chain hoist 42 so that the upper side and the lower side of the curtain wall unit 1 to be installed are parallel to the horizontal plane.

[0071] Step 3: Installing a real-time tilt angle measuring device 5 on the panel of the curtain wall unit 1 to be installed, for real-time observation of the tilt angle of the curtain wall unit 1 in a direction perpendicular to the panel;

[0072] In this step, the real-time tilt angle measuring device includes an angle measuring plate 51, a rotating shaft 52, a pointer 53 and a hanging ball 54. The angle measuring plate 51 can be rotatably arranged on the rotating shaft 52, the pointer 53 can be rotatably arranged on the rotating shaft 52, and the hanging ball 54 is fixedly connected to the pointer 53 and can be rotatably arranged on the rotating shaft 52.

[0073] In this embodiment, the panel is a glass panel, and a mounting frame is provided on the panel. The real-time inclination angle measuring device is installed on the mounting frame through its rotating shaft 52. The hanging ball 54 drives the pointer 53 to always point vertically downward due to the action of gravity. When the curtain wall unit 1 to be installed is tilted, the angle measuring plate 51 is tilted accordingly, so that the inclination angle of the curtain wall unit 1 to be installed is measured by the pointer 53.

[0074] Step 4: hoist the curtain wall unit 1 to be installed to the pre-installation height, move it closer to the pre-installation position, and then adjust the curtain wall unit 1 to be installed to a preset aerial posture;

[0075] This step also includes the following steps:

[0076] Step 1: Lift the curtain wall unit 1 to be installed to the pre-installation height and as close to the intended installation position as possible;

[0077] Step 2: Connect the load-bearing hanging code 21 of the curtain wall unit 1 to be installed to the upper horizontal hand chain hoist 616, and fix the other end of the upper horizontal hand chain hoist 616 to the building structure;

[0078] Step 3: The lower part of the curtain wall unit 1 to be installed is connected to the lower horizontal hand chain hoist 626 through a suction cup, and the other end of the lower horizontal hand chain hoist 626 is fixed to the building structure;

[0079] Step 4: By pulling the upper horizontal hand winch 616 and the lower horizontal hand winch 626, the aerial posture of the curtain wall unit 11 is adjusted so that the inward inclination angle of the lower part of the curtain wall unit 11 in the direction perpendicular to the enclosure surface is consistent with the design angle with an error of no more than ±1°. The actual angle can be measured and read in real time by a real-time inclination angle measuring device.

[0080] Step 5: Hang the curtain wall unit 1 to be installed on the building structure and perform a pre-positioning;

[0081] This step also includes:

[0082] By means of the cooperation of the hoisting equipment 43 and the hand hoists, the curtain wall unit 1 to be installed is slowly moved closer to the intended installation position;

[0083] The U-shaped groove of the force-bearing hanging weight 21 is hung on the corresponding vertical plate 3131 of the adapter 3, and the lower end of the curtain wall unit 1 to be installed is aligned with the lower card groove, thereby realizing a one-time pre-positioning of the curtain wall unit 1 to be installed.

[0084] Step 6: Move and adjust the curtain wall unit 1 to be installed downward along the enclosure surface, thereby realizing secondary pre-positioning of the curtain wall unit 1 to be installed;

[0085] This step also includes the following steps:

[0086] The lifting equipment is unloaded, and the hook is still kept hanging for safety reasons, so that the load of the curtain wall unit 1 to be installed is completely applied to the corresponding adapter 3 through the load-bearing hanging weight 21;

[0087] The adjusting bolt 211 on the force-bearing hanging weight 21 is adjusted so that the curtain wall unit 1 to be installed moves downward along the enclosure surface, and the lower end of the curtain wall unit 1 to be installed is inserted into the lower slot on the building structure, and stops when a preset distance is reserved from the bottom intended installation position, thereby realizing the secondary pre-positioning of the curtain wall unit 1 to be installed. In this embodiment, the preset distance is 2 cm.

[0088] Step 7: Horizontally move the curtain wall unit 1 to be installed onto the adjacent curtain wall unit 1 that has been installed;

[0089] This step also includes the following steps:

[0090] Install the limit stopper 7 at the corner of the adjacent curtain wall unit 1 that has been installed, and place a thin jack between the force-bearing hanging code 21 and the end plate 33 of the corresponding adapter 3, wherein the thin jack is arranged horizontally;

[0091] Through the thin jack, the external top force hanging code 21 moves horizontally, so that the curtain wall unit 1 to be installed is driven by the force hanging code 21 to move to the limited position of the limit block 7, that is, the curtain wall unit 1 stops in the horizontal direction.

[0092] Step 8: Move the curtain wall unit 1 to be installed downward along the enclosure surface for a second time to adjust the curtain wall unit 1 to be installed so that the curtain wall unit 1 to be installed moves downward to the intended installation position.

[0093] In this step, the adjusting bolts 211 on the load-bearing hanging brackets 21 are adjusted again, so that the curtain wall unit 1 to be installed is moved downward along the enclosure surface for a second time until it reaches the intended installation position.

[0094] Step nine: After step eight, remove the lifting parts and auxiliary parts, that is, remove the hand winches, the real-time measuring device for the inclination angle, the limit block 7, etc., and install the safety hanging code 22 on the curtain wall unit 1 to be installed so that it is hung on the corresponding adapter 3.

[0095] In this embodiment, the structures of the safety hanging weight 22 and the temporary hanging weight 23 may refer to the structure of the force-bearing hanging weight 21, which will not be described in detail here.

[0096] The present invention provides a method for installing a lower inward-inclined trapezoidal or parallelogram unit curtain wall, which mainly achieves the installation purpose through four aspects:

[0097] 1. By increasing the bearing capacity of the aluminum alloy load-bearing hanging weight 21 and adding an aluminum alloy temporary hanging weight 23, and adopting the form of hoisting pole 41 and 3-point hand chain hoist to bear the force, the upper and lower frames of the curtain wall unit 1 can be adjusted in the air to be parallel to the ground;

[0098] 2. By setting the upper and lower hand chain hoists, the lower part of the curtain wall unit 1 perpendicular to the enclosure surface is tilted inward to the designed angle in the air; the tilt angle is controlled throughout the process by the real-time tilt angle measuring device, and the tilt angle of the curtain wall unit 1 is kept within the allowable error range with the designed angle;

[0099] 3. By increasing the area of ​​the end plate 33 of the adapter 3 to provide a force-bearing base, after the aluminum alloy force-bearing hanging weight 21 is hung on the adapter 3 to bear the force, a thin jack is used to realize the horizontal movement of the curtain wall unit 1 along the enclosure surface;

[0100] 4. By increasing the adjustment stroke of the aluminum alloy load-bearing hanging weight 21, after the aluminum alloy load-bearing hanging weight 21 is hung on the adapter 3 to bear the force, the curtain wall unit 1 is moved up and down along the enclosure surface by adjusting the bolts 211 on the aluminum alloy load-bearing hanging weight 21.

[0101] The installation method of the lower inward-inclined trapezoidal or parallelogram unit curtain wall in the present invention is easy to implement and has the advantages of high installation accuracy, fast installation efficiency, orderly installation operation steps and high safety factor. The optimization of the unit curtain wall components can be easily achieved in the processing plant and can be achieved by only using common equipment and tooling on the market, and has great universal applicability.
