Description

Technical Field

[0001] The invention relates to a curtain wall facade decorative strip installation technology, and in particular to an assembled interlayer aluminum plate line system and a construction method thereof. Background Art

[0002] In modern curtain wall buildings, for decorative effects and energy-saving requirements, decorative lines are set on the exterior of the glass curtain wall, such as aluminum plate column wrapping, aluminum alloy decorative lines, etc. In terms of installation, they are generally fixed to the vertical keel of the curtain wall through connectors, with the front end of the connector fixing the decorative lines and the rear end fixing them to the vertical keel, such as the "Curtain Wall Unit with Decorative Lines" (CN 112746698 A) disclosed in the Chinese invention patent.

[0003] The direct connection with the vertical keel through the connector will have the following problems:

[0004] 1. The lateral wind load and downward gravity on the decorative lines are directly transmitted to the curtain wall keel, and finally to the wall keel support code. However, the lateral load and weight on large decorative lines are large, and the support code is difficult to resist. Therefore, the decorative lines are directly fixed on the vertical keel. It is only suitable for the case where the decorative lines are relatively small, or the curtain wall with a small vertical keel interval;

[0005] 2. The lines of aluminum plates between layers are generally full length (across the entire facade), and their level must be maintained during installation, which makes construction difficult and requires repeated measurement and leveling, which brings inconvenience to high-altitude lifting operations. Summary of the invention

[0006] The purpose of the present invention is to provide an assembled interlayer aluminum plate line system and a construction method thereof, which can improve the stability of the installation of a large-scale line system, simplify the installation components, and make the construction more convenient through system improvement.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an assembled interlayer aluminum plate line system, including a line body, the line body is connected to the curtain wall through a connecting assembly, the curtain wall includes vertical keels, transverse keels and a panel structure, the vertical keels are fixed to the main structure of the floor slab through channel steel, the connecting assembly includes a bent steel plate and a steel hanger, the bent steel plate includes a U-shaped end fixed to the channel steel and a T-shaped end connected to the steel hanger, one end of the steel hanger is provided with a hook that is plug-in-fit with the T-shaped end, and the other end is fixed to the line body.

[0008] In the above technical solution, left and right channel steels are respectively provided on the left and right sides of the vertical keel, the webs of the channel steels on both sides are attached to the left and right sides of the vertical keel and fixed by bolt assemblies, and the U-shaped end openings of the bent steel plates are inserted into the concave cavities of the channel steels on both sides and are fitted and fixed to the webs on both sides.

[0009] In the above technical solution, the channel steel includes two side wings and a web connecting the side wings, the U-shaped end is clamped in the left and right channel steels, and an adjustment space is provided between the upper and lower side wings of the channel steel.

[0010] In the above technical solution, the T-shaped end of the bent steel plate includes a vertical connecting rod welded and fixed to the U-shaped end, and a cross bar arranged perpendicularly relative to the vertical connecting rod. The cross bar has left and right clamping grooves on both sides corresponding to the vertical connecting rod, and the clamping grooves are opened upward, and a steel hanger is inserted in each clamping groove.

[0011] The above technical solution also includes a limit screw, which penetrates from one side of the steel hanger and is fixed to the T-shaped end.

[0012] In the above technical solution, the positioning slot includes a positioning slot on one side and an adjusting slot on the other side, the slot width of the positioning slot is adapted to the thickness of the steel hanger, and the slot width of the adjusting slot is greater than the thickness of the steel hanger.

[0013] In the above technical solution, the line body includes a metal frame and an aluminum plate assembly wrapped around the outside of the metal frame. The metal frame includes a plurality of L-shaped angle steels, which are overlapped end to end according to the design shape. The steel hanger is fixed on the vertical angle steel close to the curtain wall.

[0014] In the above technical solution, the line body is located at the floor between the upper and lower floors, and the upper and lower parts of the floor are transverse keels respectively. The line body is embedded between the upper and lower transverse keels and sealed by a first sealing strip; a galvanized steel plate is provided on the inner side of the line body, and the flanges at both ends of the galvanized steel plate are clamped in the sub-frame of the transverse keel and fixed by rivets, and the line body and the galvanized steel plate are sealed by a second sealing strip.

[0015] To achieve the above object, the construction scheme adopted by the present invention is: the steps are:

[0016] a. The line body is lofted at 1:1 by computer to obtain the outer contour size of the metal frame supporting the steel skeleton of the line body, and the length and position of the diagonal bracing rods in the metal frame are marked, and the position of the horizontal steel hangers is also marked; the metal frame is fixed by welding a plurality of L-shaped angle steels end to end, and deformation is paid attention to during welding, and the positioning mold is set to control deformation;

[0017] b. Wrap the metal frame with aluminum plates and fix them with rivets or screws;

[0018] c. Fix the steel hanger to the marked vertical angle steel;

[0019] After the above steps ac are completed in the factory, they are transported to the site;

[0020] d. On site, 14a# channel steel is used to fix the vertical keel. When welding with the embedded parts in the main structure of the floor slab, the height position of the hanging line body is preliminarily adjusted. At the same time, horizontal adjustment holes for the vertical keel bolt assembly are opened to ensure that the front surface of the vertical keel is flat, which is convenient for the installation of the connection assembly;

[0021] e. Put the 8mm thick bent steel piece inverted on the front of the vertical keel and weld it to the channel steel. Before welding, the height can be fine-tuned using the adjustment space between the U-shaped end of the bent steel piece and the upper and lower wings of the channel steel. This not only ensures the finished surface of the front of the bent steel piece, but also unifies the positioning of the height direction of the bent steel piece, providing the most basic reference line for the hook of the line body;

[0022] f. Hoist the line body, hook the steel hanger on the T-shaped end of the bent steel piece, and hook the hook on the steel hanger into the T-shaped end according to the position of the adjustment slot and the positioning slot. The width of the adjustment slot is greater than the thickness of the steel hanger to provide a margin for the hook. Move left and right to adjust so that the hook can be hooked in the positioning slot.

[0023] g. After the line body is installed in place, it is necessary to drive a limit screw into the steel hanger on one side to limit the line body;

[0024] h. Finally, insert sealing strips between the upper and lower edges of the line body and the horizontal keel to seal.

[0025] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0026] 1. The connection assembly in the present invention is composed of a U-shaped end and a T-shaped end. The U-shaped end is directly fixed to the channel steel, and the T-shaped end is connected to the line body through a steel hanger, so as to realize the overall hanging of the line body. The original vertical keel fixing channel steel is used as a connecting piece of the line body. First, the force is not only transmitted by the vertical keel, but also transmitted to the floor slab, so that the line body is hoisted more stably and the pressure of the vertical keel is reduced; first, the installation connection structure is simplified, and the original channel steel is used as the connection part, without adding additional components, reducing the investment of components, which is conducive to reducing costs;

[0027] 2. The body of the line is a unitized integral part, which can be pre-welded and installed in the factory. After being transported to the site, each unitized integral part is hung on the fixed bent steel plate through a steel hanger. Compared with the previous method of assembling the body of the line on site, the metal frame processing and installation accuracy is higher, which is conducive to the straightness and flatness of the final finished surface of the interlayer aluminum plate line, while also improving the construction efficiency and saving labor and materials;

[0028] 3. The bent steel plate in the connecting component consists of two components: a U-shaped bent component and an open T-shaped component. The two are easy to form and are welded into an integral component. The horizontality can be fine-tuned by using the adjustment space between the U-shaped end and the upper and lower side wings of the channel steel. This not only ensures the front finish of the steel component, but also unifies the positioning of the steel component in the height direction, providing the most basic reference line for the subsequent buckles of the steel hangers. In addition, the width difference between the positioning slot and the adjustment slot on the T-shaped end can be used to fine-tune the left and right distance of the buckle position of the steel hanger, which is convenient for the hanging of the line body. The flexible installation method brings convenience to the construction, and is more conducive to improving the flatness and straightness of the line body after installation.

DETAILED DESCRIPTION

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0038] The following description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. In addition, the terms "vertical", "horizontal", "top", "bottom", "front", "back", "upper", "lower", "inner", "outer" and the like mentioned in the embodiments of the present invention indicate the orientation or position relationship based on the attached Figure 2 The orientation or position relationship shown, or the orientation or position relationship in which the product is usually placed when in use, is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] See attached Figure 1-7 As shown, an assembled interlayer aluminum plate line system includes a line body 1, which is connected to a curtain wall 3 through a connecting assembly 2, and the curtain wall 3 includes a vertical keel 4, a horizontal keel 25 and a panel structure 6, and the vertical keel 4 is fixed to a floor main structure 7 through a channel steel 5. The connecting assembly 2 includes a bent steel plate 27 and a steel hanger 8, and the bent steel plate includes a U-shaped end 9 fixed to the channel steel 5 and a T-shaped end 10 connected to the steel hanger 8. One end of the steel hanger 8 is provided with a hook that is plugged into the T-shaped end 10, and the other end is fixed to the line body 1.

[0040] like Figure 3 , 4 As shown, the left and right sides of the vertical keel 4 are respectively provided with left and right channel steels 5, the webs of the channel steels 5 on both sides are attached to the left and right sides of the vertical keel 4, and are fixed by bolt assemblies 11, the U-shaped end 9 of the bent steel plate is inserted into the concave cavity of the channel steels 5 on both sides, and is attached and fixed with the webs 12 on both sides. The height positioning of the channel steel 5 is preliminarily adjusted when welding with the embedded parts 26 (set on the main structure 7 of the floor slab), and an adjustment hole 13 for fixing the bolt assembly 11 of the vertical keel 4 is also opened to ensure that the front surface of the vertical keel 4 is flat.

[0041] The channel steel 5 includes two side wings 14 and a web 12 connecting the side wings 14. The U-shaped end 9 is clamped in the left and right channel steels 5, and an adjustment space 15 is provided between the upper and lower side wings 14 of the channel steel 5. The 8mm thick steel piece (U-shaped bending piece + open T-shaped piece) is buckled at the front of the vertical keel 4 and welded to the channel steel 5. Since the height of the U-shaped bending piece is 80mm, the channel steel 5 is 14a# channel steel Q235B, and is placed at the position of the web 12 of the channel steel 5, there is a certain height fine adjustment distance (i.e., adjustment space 15) from the edge of the upper and lower side wings 14, see Figure 7 shown.

[0042] like Figure 5 , 6As shown, the T-shaped end 10 of the bent steel plate member 27 includes a vertical connecting rod welded and fixed to the U-shaped end 9, and a cross bar arranged perpendicularly relative to the vertical connecting rod, and the cross bar has left and right positioning grooves on both sides corresponding to the vertical connecting rod, respectively. The positioning grooves are open upward, and a steel hanger 8 is inserted into each positioning groove.

[0043] In order to improve the flexibility of installation, the positioning slot includes a positioning slot 16 on one side and an adjustment slot 17 on the other side. Figure 6 As shown, the width of the positioning slot 16 is adapted to the thickness of the steel hanger 8, and the width of the adjustment slot 17 is greater than the thickness of the steel hanger 8. The slot width difference is the buckle tolerance of the steel hanger 8, which facilitates the subsequent buckle of the line body 1. The connection component 2 also includes a limit screw 18. When the steel hanger 8 is hung, the limit screw 18 penetrates from one side of the steel hanger 8 and is fixed to the T-shaped end 10, which is used to limit the line body 1 and improve stability.

[0044] The line body 1 includes a metal frame 19 and an aluminum plate assembly 20 wrapped around the outside of the metal frame 19. The metal frame 19 includes a plurality of L-shaped angle steels, which are overlapped end to end according to the design shape. The steel hanger 8 is fixed on a vertical angle steel 21 close to the curtain wall. The line body 1 is lofted by computer at a ratio of 1:1 to obtain the outer contour dimensions of the L-shaped angle steel of the aluminum plate line metal frame 19, and the length and position of the diagonal bracing rods in the L-shaped angle steel are marked, and the position of the steel hanger 8 is also marked. Since the L-shaped angle steel is easily deformed during welding, it is necessary to make positioning molds for the angle steel separately to control deformation and quality control during production. The entire process is completed in the factory, and the quality of the finished product can be controlled.

[0045] After the processing is completed, the line body 1 is transported to the site for hoisting. The line body 1 is located on the floor between the upper and lower floors. Figure 1 , 2 As shown, the upper and lower parts of the floor slab are transverse keels 25 respectively, and the line body 1 is embedded between the upper and lower transverse keels 25 and sealed by a first sealing strip 22; a galvanized steel plate 23 is provided on the inner side of the line body 1, and the flanges at both ends of the galvanized steel plate 23 are clamped in the sub-frame of the transverse keel 25 and fixed by rivets, and the line body 1 and the galvanized steel plate 23 are sealed by a second sealing strip 24, and the first and second sealing strips provide sealing between the line body 1 and the facade of the curtain wall 3, see Figure 3 As shown, the galvanized steel plate 23 provides a closure for the curtain wall, separates the indoor and outdoor areas at the floor, prevents water seepage, and also has a heat preservation effect. The structure here is not limited to the scheme proposed in this embodiment, and various curtain wall sealing technologies in the prior art can also be selected, which will not be given as examples in this embodiment.

[0046] The construction method, the steps are:

[0047] a. The line body 1 is lofted with a computer at a ratio of 1:1 to obtain the outer contour size of the metal frame 19 supporting the steel skeleton of the line body 1, and the length and position of the diagonal bracing rods in the metal frame 19 are marked, and the position of the transverse steel hanger 8 is also marked; the metal frame 19 is fixed by welding a plurality of L-shaped angle steels end to end, and deformation is paid attention to during welding, and a positioning mold is set to control deformation;

[0048] b. The metal frame 19 is wrapped with an aluminum plate and fixed with rivets or screws;

[0049] c. Fix the steel hanger 8 to the marked vertical angle steel 21;

[0050] After the above steps ac are completed in the factory, they are transported to the site;

[0051] d. On site, 14a# channel steel is used to fix the vertical keel 4. When welding with the embedded parts 26 in the main structure 7 of the floor slab, the height position of the hanging line body 1 is preliminarily adjusted. At the same time, the horizontal adjustment hole 13 of the bolt assembly 11 of the vertical keel 4 is opened to ensure that the front surface of the vertical keel 4 is flat, which is convenient for the installation of the connection assembly 2;

[0052] e. The 8mm thick bent steel plate 27 is buckled on the front of the vertical keel 4 and welded to the channel steel 5. Before welding, the height can be fine-tuned using the adjustment space between the U-shaped end 9 of the bent steel plate 27 and the upper and lower wings of the channel steel 5. This not only ensures the front surface of the bent steel plate 27 is finished, but also unifies the positioning of the bent steel plate 27 in the height direction, providing the most basic reference line for the hook of the line body;

[0053] f. Hoist the line body 1, hook the steel hanger 8 on the T-shaped end 10 of the bent steel piece, and hook the hooks on the steel hanger 8 into the T-shaped end 10 according to the positions of the adjustment slot 17 and the positioning slot 16. The width of the adjustment slot 17 is greater than the thickness of the steel hanger 8 to provide a margin difference for the hook, and move left and right to adjust so that the hook is hooked in the positioning slot 16;

[0054] g. After the line body 1 is installed in place, it is necessary to drive a limit screw 18 into the steel hanger 8 on one side to limit the line body 1;
