Description

Technical Field

[0001] The present invention relates to the technical field of arch steel frames, and in particular to a hyperbolic arch steel frame and an installation method thereof, a hyperbolic curtain wall and an installation method thereof. Background Art

[0002] Modern architectural shapes and exterior curtain wall styles are becoming increasingly diverse, with more and more combinations of curved and flat surfaces appearing in the shapes. The use of emerging panels such as glass, aluminum plates, stone, ceramic plates, and stainless steel plates provides curtain walls with a variety of panel matching styles.

[0003] With the increasing diversity of architectural styles, curved surfaces are increasingly being constructed with protruding structures or shapes, particularly arched steel frames with large spans. However, conventional arched steel frames used in existing technologies can only be produced in a single curved shape, meaning they have an arc in only one direction. This single-curved arched steel frame is not suitable for designers' creativity and limits the design and aesthetics of building walls. Furthermore, the main keel of the arched steel frame is curved, which requires high machine precision and skilled workers to operate, making it difficult to achieve precise machining and high production costs. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a hyperbolic arch steel frame and its installation method, a hyperbolic curtain wall and its installation method with low processing precision and richer curved surface modeling.

[0005] The hyperbolic arch steel frame provided by the present invention is arranged on the outside of the wall beams and columns, and includes a hyperbolic arch steel frame body, which is fixedly connected to the facade of the wall beams and columns through multiple supports. The hyperbolic arch steel frame body is formed by connecting multiple sections of steel frame monomers in sequence. The steel frame monomers include multiple rectangular steel pieces arranged perpendicular to the arch axis of the hyperbolic arch steel frame body and main purlins connected between corresponding vertex corners of adjacent rectangular steel pieces. The main purlins are straight tube-shaped. The supports are connected between the main purlins of adjacent steel frame monomers or between adjacent main purlins on the same steel frame monomer through conversion steel pieces. The rectangular steel pieces and the conversion steel pieces are both formed by connecting four steel pipes end to end. The length of the front steel pipe of the rectangular steel piece and the length of the front steel pipe of the conversion steel piece increase sequentially from the center of the hyperbolic arch steel frame body to both ends.

[0006] The conversion steel member is arranged perpendicular to the arch axis of the hyperbolic arch steel frame body.

[0007] The steel pipes on the upper and lower sides of the conversion steel piece are equal in length to the steel pipes on the upper and lower sides of the rectangular steel piece.

[0008] In order to ensure strength, a plurality of staggered secondary keels are fixed between adjacent rectangular steel parts and between the rectangular steel parts and the conversion steel parts.

[0009] The main purlins connected to both sides of the same vertex of each rectangular steel member are coplanar and non-collinear.

[0010] To ensure strength, the cross-sectional area of the steel tube in the conversion steel part is larger than the cross-sectional area of the steel tube in the rectangular steel part.

[0011] In order to increase the stress strength of the support connection, a diagonal brace is connected between the front steel pipe and the rear steel pipe of the conversion steel part.

[0012] The installation method for a hyperbolic arch steel frame of the present invention comprises the following steps:

[0013] S1. Modeling

[0014] Based on the positions of the supports on the wall beams and columns, a physical model of the hyperbolic arch steel frame was created through BIM and divided into several steel frame units;

[0015] S2. Prefabrication

[0016] According to the information parameters of each steel frame unit in step S1, rectangular steel parts, main keels and conversion steel parts are processed and prepared in the factory;

[0017] S3. On-site assembly

[0018] According to the corresponding on-site coordinate points provided by BIM, each steel frame unit is assembled in sections using a tire frame;

[0019] S4. Measurement and layout

[0020] Draw out the control points of each section of steel frame according to the baseline of the main structure wall construction;

[0021] S5. Hoisting operation

[0022] The steel frame units processed on site are hoisted, spatial coordinate positioning is performed using a total station, each section of the steel frame units is welded and assembled, and the conversion steel parts are welded to the supports on the wall beams and columns.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] 1. Decomposing the main body of the hyperbolic arch steel frame into several steel frame units can facilitate the processing of the steel frame units in the factory, which is conducive to the realization of factory production. It can not only reduce the workload of on-site welding construction, speed up the construction speed, but also reduce the errors caused by on-site welding construction, further ensure the flatness of the main body of the hyperbolic arch steel frame, and is conducive to the uniformity after the panel is laid.

[0025] 2. Using BIM, we analyzed the model to determine the maximum chord height of the main body of the hyperbolic arch steel frame. Without affecting the visual effect, we optimized the arc with smaller curvature into a straight line. This not only adjusted the main keels in all steel frame units to straight lines, but also made all main keels curve-free. This greatly reduced the difficulty of keel processing accuracy, eased construction difficulty, and reduced subcontracting labor costs, thus reducing costs.

[0026] The hyperbolic curtain wall provided by the present invention includes the above-mentioned hyperbolic arch steel frame, and an aluminum plate system is fixedly connected to the surface of the hyperbolic arch steel frame. The aluminum plate system is composed of aluminum plate units fixed between adjacent rectangular steel parts and between rectangular steel parts and transition steel parts, connected in sequence. The aluminum plate units are surrounded by four aluminum veneers, and the splicing seams between adjacent aluminum veneers are arranged on the upper side or lower side of the corresponding top corners of the rectangular steel parts.

[0027] The installation method for a hyperbolic curtain wall of the present invention comprises the following steps:

[0028] S1. Modeling

[0029] Based on the positions of the supports on the wall beams and columns, a physical model of the hyperbolic arch steel frame was created through BIM and divided into several steel frame units. A physical model of the aluminum plate system was also created on each steel frame unit through BIM and divided into several aluminum plate units.

[0030] S2. Prefabrication

[0031] According to the information parameters of the steel frame unit and the aluminum plate unit in step S1, rectangular steel parts, main keels, conversion steel parts and aluminum plates are processed and prepared in the factory;

[0032] S3. On-site assembly

[0033] According to the corresponding on-site coordinate points provided by BIM, each steel frame unit is assembled in sections using a tire frame;

[0034] S4. Measurement and layout

[0035] Draw out the control points of each section of steel frame according to the baseline of the main structure wall construction;

[0036] S5. Hoisting operation

[0037] The steel frame units processed on site are hoisted, spatial coordinate positioning is performed using a total station, each section of the steel frame units is welded and assembled, and the conversion steel parts are welded to the supports on the wall beams and columns;

[0038] S6. Installation of aluminum plate unit

[0039] Install and inject glue on the aluminum veneer according to the coordinates of the control points.

[0040] Compared with the prior art, the present invention has the following advantages:

[0041] 1. The aluminum plate unit uses four aluminum veneers, which can effectively reduce the accumulation of installation errors of the aluminum veneers and provide installation accuracy. At the same time, the joints between the aluminum veneers are set near the top corners at the top and bottom, which does not affect the visual effect of the hyperbolic curtain wall facade.

[0042] 2. By using BIM, the aluminum veneer of the hyperbolic curtain wall can be adjusted to a single-curved panel corresponding to the main keel. Without affecting the visual effect of the hyperbolic curtain wall, the hyperbolic aluminum veneer can be converted into a single-curved aluminum veneer, which can greatly reduce the difficulty of the aluminum veneer's processing accuracy and reduce costs.
