Description

Technical Field

[0001] This invention relates to the field of curtain walls, and more particularly to a curtain wall node and construction method for an integrated HPC decorative and thermal insulation panel. Background Technology

[0002] Existing walls are usually made of bricks, which is not only unsightly but also has a long construction period. With the development of modern large and high-rise buildings, the use of curtain walls is increasing. my country has become the world's largest producer and user of building curtain walls. A curtain wall is a building envelope or decorative structure composed of panels and a supporting structure system. It has a certain displacement capacity relative to the main structure or a certain deformation capacity of its own, and does not bear the load of the main structure.

[0003] HPC integrated decorative insulation panels are one of the decorative materials for curtain walls. They adopt an integrated factory production method, which is relatively intensive in production and reasonable in resource allocation. The production process realizes the efficient use of resources and effectively promotes the green construction process of projects.

[0004] However, due to their large area and weight, HPC decorative insulation integrated panels require the installation of floor-side steel beams for connection to the main structure. Furthermore, the connection between the HPC decorative insulation integrated panels and the floor-side steel beams is difficult and not easy to fix, and it is impossible to achieve three-dimensional adjustment in the vertical, horizontal, and longitudinal directions. This results in poor installation performance, unstable connection structures, and a safety risk of objects falling from heights. The use of floor-side steel beams for connection increases the amount of steel used, thus increasing construction costs.

[0005] Therefore, there is an urgent need for a new type of HPC integrated decorative and thermal insulation panel curtain wall node and construction method to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention aims to solve the above problems, thereby providing a node and construction method for HPC integrated decorative and thermal insulation panel curtain wall. The upper transition component is directly installed on the transition steel beam, thereby eliminating the need for the floor edge steel beam, saving steel usage, reducing construction costs, enabling the HPC integrated decorative and thermal insulation panel to achieve three-dimensional adjustment in the horizontal, vertical and longitudinal directions, reducing installation difficulty, improving installation efficiency, ensuring installation accuracy and effect, and reducing the safety risk of falling objects from heights.

Any changes to the definition of components or technical features and / or formal but not substantive changes to the overall structure should be regarded as the scope of protection defined by the technical solution of the present invention.

[0038] See Figures 1 to 5 As shown, the technical solution of the present invention is as follows:

[0039] A type of HPC (High-Pressure Polymer) decorative and thermally insulated integrated panel curtain wall node is installed on the main structure. It includes an HPC decorative and thermally insulated integrated panel 1. The main structure includes several longitudinally continuous load-bearing steel beams 2, which are spaced vertically and aligned on the same vertical line. Each load-bearing steel beam 2 is an I-beam, and adjacent load-bearing steel beams 2 are parallel to each other. A structural floor slab 3 is installed on each load-bearing steel beam 2. A transition steel beam 4 is vertically fixed to the outer surface of the load-bearing steel beam 2, located below the structural floor slab 3. Ear plate assemblies connected to the structural floor slab 3 are fixed to the transition steel beam 4. These ear plate assemblies enhance the stability of the transition steel beam 4 and also help to absorb the vertical and horizontal forces, including its own weight and seismic forces. The horizontal load and wind load are transferred and distributed to the main structure through the structural floor slab 3. An upper transition component 5 is installed on the outer end of the transition steel beam 4. The upper part of the HPC decorative insulation integrated panel 1 is connected to the upper transition component 5 to form an upper connection node. A lower transition component 6 is installed on the outer surface of the structural floor slab 3 below the transition steel beam 4. The lower part of the HPC decorative insulation integrated panel 1 is connected to the lower transition component 6 to form a lower connection node. The lower connection node bears the horizontal force. Several upper and lower connection nodes are arranged along the longitudinal direction of the load-bearing steel beam 2. The number of upper and lower connection nodes is determined according to the area and weight of each HPC decorative insulation integrated panel 1. The upper connection nodes of the HPC decorative insulation integrated panel 1 achieve vertical and horizontal connection through the upper transition component 5. The lower connecting node of the HPC decorative insulation integrated panel 1 achieves three-dimensional adjustment in the vertical, horizontal, and longitudinal directions through the lower adapter component 6, thereby reducing the installation difficulty of the HPC decorative insulation integrated panel 1, ensuring installation accuracy, and improving installation efficiency. The upper adapter component 5 and the lower adapter component 6 have the same structure and both include a first connecting corner piece 7 and a second connecting corner piece 8 with the same structure. Both the first connecting corner piece 7 and the second connecting corner piece 8 are angle steel. The first connecting corner piece 7 is fixed to the outer side of the structural floor slab 3 or the outer end of the adapter steel beam 4. A longitudinal strip hole 14 is provided on the first connecting corner piece 7, and a transverse strip hole 13 is provided on the second connecting corner piece 8. The second connecting corner piece 8 abuts against the first connecting corner piece 7, and the transverse strip hole 13 and the longitudinal strip hole 14 are connected. The holes 14 are arranged in a cross pattern. Fastening bolts 9 are installed in the transverse and longitudinal slots 13 and 14 to secure the first connecting corner piece 7 and the second connecting corner piece 8 together. By adjusting the longitudinal and transverse positions of the second connecting corner piece 8, the HPC decorative insulation integrated panel 1 can achieve longitudinal and transverse displacement adjustment. Several vertical slots 10 are also provided on the second connecting corner piece 8, spaced longitudinally. An L-shaped steel column 11 is connected to each vertical slot 10 via a nut 12. By adjusting the vertical position of the L-shaped steel column 11, the HPC decorative insulation integrated panel 1 can achieve vertical displacement adjustment. The L-shaped steel column 11 on the upper adapter assembly 5 is inserted into the upper part of the HPC decorative insulation integrated panel 1.The L-shaped steel column 11 on the lower adapter assembly 6 is inserted into the lower part of the HPC decorative insulation integrated panel 1.

[0040] It should be noted that the main force transmission route of the upper connection node is: HPC decorative insulation integrated panel 1 → upper transition component 5 → transition steel beam 4 → load-bearing steel beam 2 → structural floor slab 3; in the force transmission route, the transition steel beam 4 and the load-bearing steel beam 2 are connected by reinforcing steel plates and bolts to form a semi-rigid connection. The load-bearing steel beam 2 bears the horizontal force, shear force, bending moment and other loads transmitted by the transition steel beam 4; when the transition steel beam 4 is connected to the structural floor slab 3 through the ear plate component, part of the horizontal load is transferred to the embedded part 22, and the structural floor slab 3 bears a large part of the vertical load through the embedded part 22.

[0041] The first connecting corner piece 7 includes a body 15 with a right-angled cross-section. The body 15 includes a vertical plate and a horizontal plate.

The right-angled plate 16 is made of steel plate and is welded and fixed to the vertical plate and the horizontal plate. Longitudinal slots 14 are provided on the horizontal plate and on both sides of the right-angled plate 16. The structural design of the first connecting corner piece 7 ensures its own structural stability. The right-angled plate 16 strengthens the load-bearing capacity of the first connecting corner piece 7. The longitudinal slots 14 on both sides of the right-angled plate 16 provide a basis for realizing multi-point connection with the second connecting corner piece 8.

[0042] Horizontal strip holes 13 are provided on the horizontal plate of the second connecting corner piece 8 and on both sides of the right-angle plate 16, and vertical strip holes 10 are provided on the vertical plate of the second connecting corner piece 8 and on both sides of the right-angle plate 16. By providing horizontal strip holes 13 on both sides of the right-angle plate 16, the second connecting corner piece 8 can achieve multi-point connection with the first connecting corner piece 7, ensuring a firm connection between the first connecting corner piece 7 and the second connecting corner piece 8. At the same time, by providing vertical strip holes 10 on both sides of the right-angle plate 16, the second connecting corner piece 8 can achieve connection with multiple L-shaped steel columns 11, ensuring a firm connection between the second connecting corner piece 8 and the HPC decorative insulation integrated panel 1.

[0043] The L-shaped steel column 11 is made of round steel bent into a vertical part and a horizontal part. The vertical part is inserted into the upper part or the lower part of the HPC decorative insulation integrated panel 1, and the horizontal part is inserted into the vertical strip hole 10 of the second connecting corner piece 8. The nut 12 and the horizontal part are threaded together to fasten the second connecting corner piece 8, the L-shaped steel column 11 and the HPC decorative insulation integrated panel 1 together. The L-shaped steel column 11 ensures the connection between the HPC decorative insulation integrated panel 1 and the second connecting corner piece 8. The tightness of the nut 12 is adjusted to ensure the firmness of the connection between the HPC decorative insulation integrated panel 1, the L-shaped steel column 11 and the second connecting corner piece 8, and also realizes the adjustment of the position of the L-shaped steel column 11 in the vertical strip hole 10.

[0044] The ear plate assembly includes an upper ear plate 17 and a lower ear plate 18 with identical structures. Both the upper ear plate 17 and the lower ear plate 18 include a positioning plate 19, which is a steel plate. A perforated ear plate 20 is vertically fixed on the positioning plate 19. The perforated ear plate 20 is also a steel plate and has through holes. Two reinforcing ribs 21 are welded to both sides of the perforated ear plate 20. The two reinforcing ribs 21 on each side are welded to the positioning plate 19. Fastening bolts 9 that connect the upper ear plate 17 and the lower ear plate 18 are installed in the through holes on the upper ear plate 17 and the lower ear plate 18. The above structural design ensures the structural strength of the upper ear plate 17 and the lower ear plate 18. At the same time, the upper ear plate 17 and the lower ear plate 18 are connected together by the fastening bolts 9 to form an effective connection.

[0045] Embedded parts 22 are pre-embedded inside the structural floor slab 3. Embedded parts 22 include an upper plate 23 and a lower plate 24, both made of steel plates. The upper and lower plates 23 and 24 are spaced vertically apart and parallel to each other. Several supports 25 are vertically fixed between the upper and lower plates 23 and 24. Each support 25 is made of round steel, with its upper end welded to the bottom surface of the upper plate 23 and its lower end welded to the top surface of the lower plate 24. The lower plate 24... The bottom surface is flush with the bottom surface of the structural floor slab 3. The upper ear plate 17 is welded to the bottom surface of the lower plate 24. The sides of the upper plate 23 and the lower plate 24 are flush with the sides of the structural floor slab 3. The first connecting corner piece 7 on the lower transition assembly 6 is welded to the sides of the upper plate 23 and the lower plate 24. By setting the embedded part 22 in the structural floor slab 3, the upper ear plate 17 is fixedly connected to the embedded part 22, and the first connecting corner piece 7 on the lower transition assembly 6 is also fixed.

[0046] The transition steel beam 4 includes an upper steel beam segment 26 and a lower steel beam segment 27, both of which are I-beams. The length of the upper steel beam segment 26 is shorter than that of the lower steel beam segment 27. The upper steel beam segment 26 and the lower steel beam segment 27 are stacked and fixed together, with their left ends flush. The upper steel beam segment 26 and the lower steel beam segment 27 are welded together. The left ends of both the upper steel beam segment 26 and the lower steel beam segment 27 are fixed to the side of the load-bearing steel beam 2. The upper and lower flanges of the left ends of the upper steel beam segment 26 and the lower steel beam segment 27 are removed. The webs of the upper steel beam segment 26 and the lower steel beam segment 27 are welded to the outer surface of the web of the load-bearing steel beam 2. Two reinforcing steel plates are bolted to both sides of the web of beam segment 27. Both reinforcing steel plates are welded to the web of the load-bearing steel beam 2 and between the upper and lower flanges. The lower ear plate 18 is welded to the right side of the surface of the lower steel beam segment 27 and corresponds to the upper ear plate 17. The upper steel beam segment 26 is located between the load-bearing steel beam 2 and the lower ear plate 18. The first connecting corner piece 7 on the upper transition assembly 5 is welded to the right end of the lower steel beam segment 27. The above structural arrangement ensures the firm connection between the transition steel beam 4 and the load-bearing steel beam 2, and also realizes the fixed connection with the lower ear plate 18 and the first connecting corner piece 7 on the upper transition assembly 5, ensuring the firmness of the connection structure.

[0047] The outer end of the lower steel beam section 27 is flush with the outer edge of the structural floor slab 3; the above structural arrangement ensures that the upper transition component 5 and the lower transition component 6 are on the same longitudinal straight line, ensuring the flatness of the HPC decorative insulation integrated panel 1 during installation.

[0048] A construction method for a curtain wall node of an integrated HPC decorative and thermal insulation panel includes the following steps:

[0049] S1. Determine the number of upper and lower connection nodes based on the area and weight of each HPC decorative insulation integrated panel 1, wherein each upper connection node corresponds to each lower connection node.

[0050] S2. When the structural floor slab 3 is poured, the same number of embedded parts 22 as the lower connection node are pre-embedded to ensure that each lower transition component 6 and each ear plate component are installed on the embedded parts 22.

[0051] S3. Mark the fixed points of each transition steel beam 4 on the outer side of the load-bearing steel beam 2 in advance. The number of fixed points is consistent with the number of upper connection nodes, and the position of each fixed point corresponds to the position of each embedded part 22.

[0057] S9. Install L-shaped steel columns 11 on the upper and lower parts of each HPC decorative insulation integrated panel 1, with the same number of vertical strip holes 10 as each second connecting corner piece 8.

[0058] S10. Hoist the HPC decorative insulation integrated panel 1 to the installation position, and pre-tighten the L-shaped steel to the second connecting corner piece 8 with nut 12 to achieve the pre-installation of HPC decorative insulation integrated panel 1;

[0059] S11. Based on the actual installation situation on site, tighten the fastening bolts 9 to adjust the longitudinal and lateral positions of the second connecting corner piece 8, and tighten the nuts 12 to adjust the vertical position of the L-shaped steel column 11, thereby driving the HPC decorative insulation integrated panel 1 to achieve three-dimensional adjustment in the longitudinal, lateral and vertical directions.

[0060] S12. After the HPC decorative insulation integrated panel 1 has been adjusted, tighten the fastening bolts 9 and nuts 12 to fix it.

[0061] This invention fixes a transition steel beam 4 on a load-bearing steel beam 2, installs an upper transition component 5 on the transition steel beam 4, embeds an embedded part 22 in the structural floor slab 3 below the load-bearing steel beam 2, installs a lower transition component 6 on the embedded part 22, and installs L-shaped steel columns 11 on the upper and lower parts of the HPC decorative insulation integrated panel 1. The L-shaped steel columns 11 connect the HPC decorative insulation integrated panel 1 to the upper transition component 5 and the lower transition component 6, thereby enabling the HPC decorative insulation integrated panel 1 to be installed and fixed on the main structure. The upper connection node bears vertical and horizontal loads, including self-weight and seismic forces, as well as horizontal wind loads, while the lower connection node bears horizontal forces. The upper transition component 5 directly... Installed on the transition steel beam 4, the steel beam at the edge of the building is eliminated, saving steel usage and reducing construction costs. Longitudinal strip holes 14, transverse strip holes 13, and vertical strip holes 10 are set on the upper transition component 5 and the lower transition component 6, enabling the second connecting corner piece 8 to achieve transverse and longitudinal displacement adjustment, and enabling the L-shaped steel column 11 to achieve vertical displacement adjustment. This, in turn, drives the HPC decorative insulation integrated panel 1 to achieve three-dimensional adjustment in transverse, longitudinal, and vertical directions, reducing the installation difficulty of the HPC decorative insulation integrated panel 1, improving installation efficiency, ensuring the installation accuracy and effect of the HPC decorative insulation integrated panel 1, ensuring the firmness of the connection structure, and reducing the safety risk of falling objects from heights.
