Description

Technical Field

[0001] This invention relates to the field of curtain wall construction technology, and specifically to an adjustable curtain wall steel support and its construction method. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for a building, hung like a curtain, hence also called a "curtain wall." It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. Curtain walls are classified according to the panels used: glass curtain walls, metal panel curtain walls, and non-metallic panel (excluding glass) curtain walls. Among them, glass curtain walls are an aesthetically pleasing and novel method of building wall decoration, a prominent feature of modern high-rise buildings, and are widely used today. In the construction of irregularly shaped glass curtain walls, such as spherical glass curtain walls, both aesthetics and economic efficiency must be considered; therefore, the selection of steel supports is crucial.

[0003] The commonly used adjustable steel supports for curtain walls, such as CN217480524U, CN208251382U, and CN 202787505U, are mostly used in concrete structures and less so in steel structures. Moreover, most of them are mechanical structures, and their adjustment direction is three-dimensional, which cannot meet the multi-dimensional adjustment needs of spherical domes.

[0004] Therefore, developing a curtain wall steel support with a simple structure that can meet the multi-dimensional adjustment needs of spherical domes is of great practical significance. Summary of the Invention

[0005] Due to the aforementioned deficiencies in the existing technology, the present invention provides a curtain wall steel support with a simple structure that can meet the multi-dimensional adjustment needs of a spherical dome, overcoming the shortcomings of existing curtain wall steel supports that cannot meet the multi-dimensional adjustment needs of a spherical dome.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustable curtain wall steel support includes a base plate, a limiting rib, a central connecting rib, and a central cylinder;

[0008] The central cylinder is perpendicularly connected to the substrate, and the axis of symmetry of the central cylinder passes through the center of symmetry of the substrate. A through hole A matching the central cylinder is opened at the center of the substrate, and multiple through holes B are opened on the cylinder wall of the central cylinder.

[0009] There are multiple central connecting ribs, which are evenly distributed around the circumference of the central cylinder and the axis of symmetry of the central cylinder is located in the plane of the central connecting ribs.

[0010] There are multiple sets of limiting ribs, and each set of limiting ribs corresponds to a central connecting rib. Each set of limiting ribs includes two limiting sub-ribs forming a V shape. The central connecting rib is fixedly connected to the connection of the two limiting sub-ribs. The two limiting sub-ribs that are closest to each other in two adjacent sets of limiting ribs are parallel to each other. The position between the two limiting ribs is the steel keel insertion interface.

[0011] The adjustable curtain wall steel support of this invention has a reasonable structural design. The curtain wall steel support is fixed to the steel structure through the cooperation of the central cylinder and the adapter. It can be rotated to adjust the horizontal position as needed, and the vertical position can be adjusted by adjusting the adapter. In addition, the adapter can be installed in the desired position, with multiple adjustment dimensions and good applicability. The main components can be processed in the factory, thereby reducing the amount of on-site construction. It has low construction difficulty, high construction efficiency and high construction quality, and good application prospects.

[0012] As a preferred technical solution:

[0013] As described above, an adjustable curtain wall steel support has a base plate that is an equilateral hexagonal plate, six central connecting ribs, and six sets of limiting ribs.

[0014] An adjustable curtain wall steel support as described above also includes an adapter cylinder;

[0015] The outer diameter of the adapter tube is smaller than the inner diameter of the central tube, and the tube wall of the adapter tube has multiple waist-shaped holes that match the through hole B.

[0016] As described above, in an adjustable curtain wall steel support, the through hole B is a screw hole. After the bolt is screwed into the through hole B, it passes through the waist-shaped hole of the adapter cylinder and is connected to the nut to fix the adapter cylinder to the curtain wall steel support.

[0017] As described above, in an adjustable curtain wall steel support, one end of the adapter tube is fixedly connected to the curtain wall steel support, and the other end is inserted into the embedded plate connector. The embedded plate connector is fixed on the embedded plate on the steel structure, and the embedded plate on the steel structure is fixedly connected to the main steel structure. The adapter tube and the embedded plate connector are welded and fixed.

[0018] As described above, an adjustable curtain wall steel support has multiple waist-shaped holes evenly distributed around the circumference of the central cylinder on the base plate, and the base plate waist-shaped holes are located between the two closest limiting sub-ribs in two adjacent sets of limiting ribs.

[0019] As described above, an adjustable curtain wall steel support has multiple through holes B evenly distributed around the circumference of the central tube's axis of symmetry.

[0020] Furthermore, the present invention also provides a construction method for an adjustable curtain wall steel support as described above, comprising the following steps:

[0021] (1) After processing the base plate, limiting rib, central connecting rib and central cylinder, weld them into a whole;

[0022] (2) Machining the adapter tube and fixing the adapter tube to the curtain wall steel support with bolts;

[0023] (3) Determine the position of the embedded plate connector based on the BIM model data and weld the embedded plate connector to the embedded plate on the steel structure at the specified position. It has high applicability and accuracy and can avoid the problem of misalignment when setting the embedded plate connector during the design.

[0024] (4) Insert the end of the adapter tube away from the curtain wall steel support into the embedded plate tube and weld it in place. Adjust the height by welding the adapter tube to the embedded plate tube, and adjust the circumferential angle by rotating the support to achieve the effect of three-dimensional adjustment.

[0025] (5) After inserting the steel keel into the steel keel insertion interface, fix the steel keel to the curtain wall steel support by bolts or welding.

[0026] This invention analyzes the data of the BIM model to identify patterns and variations. It uses a circular tube sleeve to address the structural deviation of the sphere's radius from the surface points to the center of the sphere. A base is set up with the sphere's surface as the curved surface. The support base is perpendicular to the sphere's radius. The center of the base is used as the base point. The circumferential fixing point is determined by combining the center line of the steel keel members. A waist-shaped hole is opened to adjust the circumferential installation error.

[0027] The above technical solution is only one feasible technical solution of the present invention. The scope of protection of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0028] The above invention has the following advantages or beneficial effects:

[0029] (1) The adjustable curtain wall steel support of the present invention has a reasonable structural design. The curtain wall steel support is fixed on the steel structure through the cooperation of the central cylinder and the adapter. It can be rotated to achieve horizontal position adjustment as needed. The vertical position can be adjusted by adjusting the adapter. In addition, the adapter can be installed in the desired position, with multiple adjustment dimensions and good applicability. The main components can be processed in the factory, thereby reducing the amount of on-site construction. The construction difficulty is low, the construction efficiency is high and the construction quality is high.

[0030] (2) The adjustable curtain wall steel support of the present invention allows the fabrication, welding and painting of steel components to be completed in the factory to the greatest extent possible, which greatly reduces the labor intensity on site and shortens the construction period.

[0031] (3) The adjustable curtain wall steel support of the present invention reduces on-site welding, improves construction efficiency, and ensures accurate installation and positioning, thereby improving construction quality.

[0032] (4) The construction method of the adjustable curtain wall steel support of the present invention is simple to operate, reduces on-site construction difficulty, reduces safety risks, is environmentally friendly and reliable, and has good application prospects. Attached Figure Description

Detailed Implementation

[0037] The structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0038] Example 1

[0039] An adjustable curtain wall steel support, such as Figures 1-3 As shown, it includes a base plate 1 (equilateral hexagonal plate), a limiting rib plate 2, a central connecting rib plate 3, a central cylinder 4, and a transition cylinder 5;

[0040] The central cylinder 4 is perpendicularly connected to the substrate 1 and the axis of symmetry of the central cylinder 4 passes through the center of symmetry of the substrate 1. A through hole A matching the central cylinder 4 is opened at the center of the substrate 1. Three central cylinder screw holes 10 (i.e. through holes B) are evenly distributed around the axis of symmetry of the central cylinder 4 on the cylinder wall.

[0041] There are six central connecting ribs 3. The six central connecting ribs 3 are evenly distributed around the circumference of the central cylinder 4, and the axis of symmetry of the central cylinder 4 is located in the plane where the central connecting ribs 3 are located.

[0042] There are six sets of limiting ribs 2, and each set of limiting ribs 2 corresponds to a central connecting rib 3. Each set of limiting ribs 2 includes two limiting sub-ribs forming a V shape. The central connecting rib is fixedly connected to the connection of the two limiting sub-ribs. The two limiting sub-ribs that are closest to each other in two adjacent sets of limiting ribs are parallel to each other. The position between the two limiting ribs is the steel keel insertion interface. The base plate 1 also has six base plate waist-shaped holes 11 evenly distributed around the circumference of the central cylinder. The base plate waist-shaped holes 11 are located between the two limiting sub-ribs that are closest to each other in two adjacent sets of limiting ribs.

[0043] The outer diameter of the adapter tube 5 is smaller than the inner diameter of the central tube 4, and the tube wall of the adapter tube 5 has multiple waist-shaped holes 9 that match the screw holes 10 of the central tube. After the bolt is screwed into the screw hole 10 of the central tube, it passes through the waist-shaped hole 9 of the adapter tube and is connected to the nut to fix the adapter tube to the curtain wall steel support.

[0044] One end of the adapter tube 5 is fixedly connected to the curtain wall steel support, and the other end is inserted into the embedded plate connector 6. The embedded plate connector 6 is fixed on the embedded plate 7 on the steel structure, and the embedded plate 7 on the steel structure is fixedly connected to the main steel structure 8. The adapter tube 5 and the embedded plate connector 6 are welded and fixed.

[0045] The processing steps are as follows:

[0046] 1. Material preparation: Prepare 12mm and 6mm thick Q235B steel plates, and Q235B steel pipes with specifications of ￠165*8 and ￠140*6; prepare a number of M12 and M16 bolts as needed.

[0047] 2. Cut materials according to the drawing requirements:

[0048] A: A 12mm thick steel plate is cut into a regular hexagonal connecting steel plate with a side length of 235mm (base plate 1: 12mm thick connecting steel plate). A 170mm diameter round hole is made in the middle part, and 6 13mm*50mm M12 bolt slotted holes (base plate slotted hole 11) are made near the edge. The center lines of the slotted holes form a 60° angle with each other.

[0049] B: Cut 6mm thick steel plate into ribs. Rib specifications: 100mm*160mm (limiting rib 2: 6mm thick rib) and 56mm*160mm (center connecting rib 3: 6mm thick rib). Cut and set aside.

[0050] C: Cut the ￠165*8 steel pipe into two specifications with lengths of 170mm (center cylinder 4: ￠165*8 steel pipe) and 120mm (embedded plate connecting cylinder 6: ￠165*8 steel pipe). Center cylinder 4 needs to be drilled with 3 M16 bolt holes (i.e., center cylinder bolt holes 10), with a hole diameter of ￠17.

[0051] D: Cut the ￠140*6 steel pipe into sections with a length of 270mm (Adapter 5: ￠140*6 steel pipe). Adapter 5 needs to be drilled with 3 M16 waist bolt holes (i.e., adapter waist hole 9), with a hole diameter of ￠17 and an arc length of 50mm.

[0052] The construction method for the aforementioned adjustable curtain wall steel supports includes the following specific steps:

[0053] Step 1: Mark the positioning lines of the assembled welding components. With the positioning center of the base plate 1 as the center, and the center of the M12 waist hole and the center of the circle as the reference point, draw a line and draw 6 equal segments with an included angle of 60° between each other. Each segment passes through the center of the circle. Rotate the 6 equal segments clockwise by 30° to determine the positioning line of the center connecting rib 3, and offset it 58mm to the left and right to determine the positioning line of the limiting rib 2.

[0054] Step 2: Assemble and weld the base plate 1 and the center cylinder 4. During welding, the center of the M16 bolt hole of the center cylinder 4 and the center of the waist-shaped hole on the base plate 1 are on the same vertical plane, and the bottom ends of the base plate 1 and the center cylinder 4 are flush. The center of the 170mm diameter hole on the base plate 1 coincides with the center of the cross-sectional circle of the center cylinder 4.

[0055] Step 3: Assemble and weld the central connecting rib plate 3. After verifying the positioning line of the central connecting rib plate 3, assemble and weld the central connecting rib plate 3 vertically to the central cylinder 4.

[0056] Step 4: Assemble and weld the limiting rib plate 2. After verifying the positioning line of the limiting rib plate 2, assemble and weld the limiting rib plate 2 vertically to the base plate 1. Weld the side and center connecting rib plate 3 according to the requirements shown in the figure to complete the disc support.

[0057] Step 5: After assembly, the disc support, adapter cylinder 5, embedded plate connector cylinder 6 and other parts are ground, rusted, degreased and cleaned. After cleaning, they are coated with primer and fluorocarbon paint topcoat, packed and boxed and transported to the project site for use.

[0058] Step 6: Based on the BIM model data, locate the positioning line of the embedded plate connector 6 on the steel structure embedded plate according to the dimensions shown in the figure, and assemble and weld the embedded plate connector 6 to the steel structure embedded plate.

[0059] Step 7: Inspect and verify the assembled disc support. After verification, assemble it with the adapter tube 5 through the M16 bolt holes. Position the disc support on the embedded plate connector 6 through the adapter tube 5. After verifying that the dimensions are correct, weld the embedded plate connector 6 firmly to the steel structure embedded plate through the adapter tube 5.

[0060] Step 8: Clean the welding slag, grind to remove rust, oil and dirt, and then apply primer and fluorocarbon paint;

[0061] Step 9: After inserting the steel keel into the steel keel insertion interface, fix the steel keel to the curtain wall steel support by bolts or welding.

After application, it was found that the device of the present invention meets the multi-dimensional adjustment needs of the spherical dome. Through bolted and welded assembly, it has good reliability, multiple adjustment dimensions, high installation accuracy, and good applicability.
