Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an installation and construction device for angled glass curtain walls. Background Technology

[0002] In contemporary urban construction, distinctive large-scale public buildings have become key carriers for shaping a city's image. The increasing diversity of building exteriors has led to curtain walls, as a core means of showcasing a city's character, becoming increasingly complex in form and structure, with a surge in "tall, large, unique, innovative, and challenging" projects. Faced with this trend, traditional hoisting methods, due to their low efficiency and safety hazards, have become inadequate and fail to meet the dual standards of modern construction regarding schedule and safety.

[0003] In contemporary architectural design, the facades of large public buildings, especially stadiums, often rely on complex curtain wall systems to achieve unique visual effects. In recent years, non-traditional curtain wall forms such as tilted curtain walls, large-segment curtain walls, and curved curtain walls have been widely used in important public projects. Their complexity and diversity in form have brought numerous technical challenges to on-site construction. At the same time, in actual construction, to present the building's appearance and achieve facade closure as early as possible, the curtain wall construction cycle is often significantly compressed, placing higher demands on the quality, efficiency, and process management of curtain wall installation.

[0004] Currently, the installation of glass in reverse-angle inclined curtain walls (i.e., the curtain wall and the ground form an acute angle) is done through segmented hoisting and installation, which results in a long construction period and is detrimental to issues such as water tightness of the exterior facade. This is particularly problematic during the construction of landmark buildings such as large stadiums, convention centers, and hangars, where such issues severely restrict construction efficiency. In such cases, it is necessary to address the overlapping work surfaces of roof installation, eaves installation, and curtain wall facade installation, while also allowing time for outdoor ground flooring construction and interior finishing work, while simultaneously achieving high standards in construction safety, quality, and schedule.

[0005] Therefore, there is a need for an installation and construction device for tilted glass curtain walls that can solve the problems of segmented hoisting and long installation cycles in existing technologies. Summary of the Invention

[0006] The purpose of this invention is to provide an installation and construction device for tilted glass curtain walls, which can solve the problems of segmented hoisting and long installation cycles of tilted glass curtain walls in the prior art.

[0007] This invention is implemented as follows:

[0008] An installation and construction device for an angled glass curtain wall includes a winch support, a top support for the angled curtain wall, a winch, a middle support for the angled curtain wall, a hoisting rope, a top pulley, and a middle pulley. The winch is installed on the ground outside the angled glass curtain wall via the winch support. A pair of top supports for the angled curtain wall are installed on the main steel structure ring beam, and each top support for the angled curtain wall is equipped with a top pulley. The middle support for the angled curtain wall is installed on the main steel structure and located above the glass installation position. The middle pulley is installed in the middle of the middle support for the angled curtain wall. One end of the hoisting rope is connected to the winch, and the other end of the hoisting rope passes sequentially around the top pulley and the middle pulley and connects to the glass assembled on the ground.

[0009] The winch support includes a support body and counterweights. One or more counterweights and the winch are installed on the support body, which is supported on the ground by outriggers.

[0010] The aforementioned top support for the inclined curtain wall includes an F-type bracket and a clamp. The open end of the F-type bracket is fitted onto the upper part of the main steel structure ring beam, and the clamp is fitted onto the lower part of the main steel structure ring beam. The clamp and the open end of the F-type bracket are detachably connected to form a closed-loop structure that hugs the main steel structure ring beam, so that one end of the F-type bracket is fixedly installed on the main steel structure ring beam, and the other end of the F-type bracket extends horizontally to the outside of the inclined glass curtain wall.

[0011] The F-type bracket consists of two sets of parallel bracket units, with a top pulley installed between the two sets of bracket units.

[0012] The central support structure of the inclined curtain wall includes a horizontal bar, adjusting sleeves, adapters, T-shaped connectors, and an adjustable hoisting frame. A pair of adjusting sleeves are slidably and adjustablely fitted onto the horizontal bar. One end of a pair of adapters is fixedly installed on a pair of adjusting sleeves, and the other end of a pair of adapters is fixedly connected to the small end of a pair of T-shaped connectors. Several installation support points are arranged on the main steel structure according to the glass installation position, and a pair of adapters are detachably installed on two of the installation support points. The central pulley is installed on the large end of the T-shaped connector through the adjustable hoisting frame.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention assembles the curtain wall as a whole on the ground and then hoists it in one go, thereby reducing the amount of high-altitude work by 30% to 40%. This not only significantly improves the safety and reliability of construction, but also effectively shortens the construction period by increasing efficiency and reducing labor and machinery consumption, achieving a significant saving in labor costs. It also reduces the cross-operation of curtain wall construction with other processes, and has important guiding and reference significance for multi-disciplinary cross-construction under complex engineering conditions.

[0015] 2. This invention uses top and middle pulleys installed on the top and middle supports of the inclined curtain wall to facilitate the overall hoisting of the assembled glass using winches and ropes. The middle support of the inclined curtain wall has high adjustment flexibility and can adapt to glass hoisting and installation at different locations, thereby greatly improving construction efficiency while ensuring hoisting safety, increasing curtain wall construction efficiency by about 40% and shortening the construction period.

The winch 3 is installed on the ground outside the angled glass curtain wall 8 via the winch support 1. A pair of top supports 2 for the angled curtain wall are installed on the main steel structure ring beam 9, and each top support 2 is equipped with a top pulley 6. The middle support 4 for the angled curtain wall is installed on the main steel structure 13 and located above the glass installation position. The middle pulley 7 is installed in the middle of the middle support 4. One end of the hoisting rope 5 is connected to the winch 3, and the other end of the hoisting rope 5 passes sequentially around the top pulley 6 and the middle pulley 7 and is connected to the glass 10 assembled on the ground.

[0026] The glass units of the angled glass curtain wall 8 are assembled on the ground to form glass 10. Compared with the individual hoisting and high-altitude installation of glass units, the ground assembly method can improve the assembly accuracy and efficiency of the glass units. The assembled glass 10 is hoisted to the glass installation position as a whole by a winch 3 via ropes 5, top pulleys 6 and middle pulleys 7, and then high-altitude operations are carried out, thereby effectively improving construction efficiency and solving the problems of segmented hoisting and long construction cycle of the reverse-angled curtain wall glass.

[0027] Preferably, the top pulley 6 and the middle pulley 7 can be φ100 pulleys, or the pulley specifications can be adapted to the actual usage requirements. The top support 2 and the middle support 4 of the inclined curtain wall are used to provide installation fulcrums for the top pulley 6 and the middle pulley 7, respectively, thereby facilitating the hoisting of the glass 10 by the winch 3 and the hoisting rope 5.

[0028] Please see the appendix Figure 4 and attached Figure 5 The winch support 1 includes a support body 11 and a counterweight 12. One or more counterweights 12 and the winch 3 are installed on the support body 11. The support body 11 is supported on the ground by outriggers (not shown in the figure).

[0029] Preferably, the support body 11 can be formed by welding multiple 100*50*4mm galvanized square tubes, with a specification size of 1495*1600mm, and the support body 11 has a rectangular frame structure.

[0030] The specifications of winch 3 can be selected according to the actual hoisting requirements. Preferably, a winch with a weight of 1.5 tons and model JK-1.5 can be used.

[0032] Preferably, steering wheel outriggers are installed at all four corners of the main body 11. During hoisting, 15mm thick wooden templates are placed underneath to support the outriggers. When moving, the steering pulleys are lowered and the outriggers are retracted. The outriggers are commonly used support components in this field, and the outrigger type can be adapted to the actual support requirements. Their specific structure and usage will not be described in detail here.

[0033] Please see the appendix Figure 6 The top support 2 of the inclined curtain wall includes an F-type support 21 and a clamp 22. The open end of the F-type support 21 is fitted onto the upper part of the main steel structure ring beam 9, and the clamp 22 is fitted onto the lower part of the main steel structure ring beam 9. The clamp 22 and the open end of the F-type support 21 are detachably connected by an M12 stainless steel bolt group to form a closed loop structure that hugs the main steel structure ring beam 9, so that one end of the F-type support 21 is fixedly installed on the main steel structure ring beam 9, and the other end of the F-type support 21 extends horizontally to the outside of the inclined glass curtain wall 8.

[0034] The clamp 22 and the open end of the F-type bracket 21 form a closed-loop structure that matches the cross-sectional shape and size of the main steel structure ring beam 9, thus enabling the F-type bracket 21 to be stably installed on the main steel structure ring beam 9. The clamp 22 and the open end of the F-type bracket 21 are connected by an M12 stainless steel bolt group, which is convenient and quick to assemble and disassemble, and can be reused after disassembly.

[0036] Preferably, the support unit can be made of 100*100*5mm galvanized square tube welded together, and two sets of support units are connected and fixed by 100*100*5mm galvanized square tube to form an integrated F-type support 21.

[0037] Please see the appendix Figure 1 and attached Figure 7 The central support 4 of the inclined curtain wall includes a horizontal bar 41, an adjusting sleeve 42, a transition piece 43, a T-shaped connector 44, and an adjustable hoisting frame 45. A pair of adjusting sleeves 42 are slidably and adjustablely fitted onto the horizontal bar 41. One end of a pair of transition pieces 43 is fixedly installed on a pair of adjusting sleeves 42, and the other end of a pair of transition pieces 43 is fixedly connected to the small end of a pair of T-shaped connectors 44. Several installation support points 14 are arranged on the main steel structure 13 according to the glass installation position. A pair of transition pieces 43 are detachably installed on two of the installation support points 14 by bolt groups. The central pulley 7 is installed on the large end of the T-shaped connector 44 by the adjustable hoisting frame 45.

[0038] Preferably, the crossbar 41 can be made of 100*100*5mm galvanized square tube, and the adjusting sleeve 42 can be made of 100*100*6mm galvanized square tube.

[0039] Preferably, the adapter 43 can be made by vertically connecting two 8mm steel plates, and the mounting fulcrum 14 can be made of steel plate, with one steel plate welded to the adjusting sleeve 42, and the other steel plate connected to the mounting fulcrum 14 by bolts. The end of the other steel plate is welded and fixed to the small end of the T-shaped connector 44.

[0040] Preferably, the adjustable hoisting frame 45 can be a U-shaped double-layer hoisting frame, and the two layers of hoisting frames can be adjusted by means of slide rails, which facilitates the installation and position adjustment of the middle pulley 7.

[0041] Please see the appendix Figure 1 To be continued Figure 7 During construction, the glass units of the angled inclined glass curtain wall 8 are pre-assembled into an integral glass 10 on the ground. The size of the glass 10 can be adaptively adjusted according to the actual construction conditions. Ground assembly reduces the number of glass unit hoisting operations and the amount of high-altitude construction. Moreover, ground assembly has higher assembly accuracy than high-altitude assembly, thereby improving the construction efficiency and quality of the reverse angled inclined curtain wall.

[0042] Based on the dimensions and weight of the glass 10, the weight and quantity of the counterweights 12 for the winch bracket 1 are calculated, and the specifications of the winch 3 are determined. Based on the calculation results, the bracket body 11 is fabricated using galvanized square tubing. The bracket body 11 is installed on the ground outside the inclined glass curtain wall 8 via support legs, and counterweights 12 of appropriate weight are provided. The winch 3 is then fixedly installed onto the bracket body 11.

[0043] F-type brackets 21 are made of galvanized square tubing. The open ends of the F-type brackets 21 are installed onto the main steel structure ring beam 9 (higher than the angled glass curtain wall 8) using clamps 22 to form the top brackets 2 of the inclined curtain wall. A pair of top brackets 2 of the inclined curtain wall can be installed on the top two sides of the angled glass curtain wall 8.

[0044] Based on the dimensions of the glass 10, several mounting points 14 are arranged on the main steel structure 13. These mounting points 14 can be arranged in a grid pattern for installing the central support 4 of the inclined curtain wall. Depending on the installation position of the glass 10, the central support 4 of the inclined curtain wall is installed onto the two mounting points 14 above the glass installation position. Alternatively, the central support 4 of the inclined curtain wall can be installed onto the corresponding mounting points 14 based on the installation position of the glass 10, making position changes convenient and quick.

[0045] When installing glass 10, the position of the adjusting sleeve 42 on the crossbar 41 and the spacing between a pair of adjusting sleeves 42 can be adjusted according to the width of glass 10 to facilitate stable hoisting of glass 10. After adjustment, the adjusting sleeve 42 is locked and connected to the crossbar 41 by bolts; then the adapter 43 is connected to the installation support point 14 at the corresponding position by bolt group.

[0046] Preferably, the lifting ropes 5 can be made of φ12 steel wire rope. One end of the two lifting ropes 5 is connected to the winch 3, and the other end of the two lifting ropes 5 is respectively wound around the two top pulleys 6 and the two middle pulleys 7 and then connected to the lifting points at both ends of the top of the glass 10. By starting the winch 3, the glass 10 can be hoisted to the designated height for installation using the lifting ropes 5.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention.
