Description

Technical Field

[0001] The invention relates to the technical field of building roofs, in particular to an integrated construction method for an antique building variable-curvature double-arc goose-shaped roof. Background Art

[0002] Many traditional ancient buildings are wooden structures, and most of them no longer have residential and use functions. However, with the development of modern cities and new technologies, new buildings pursue antique structures to achieve beauty, elegance, and architectural functions, which has become one of the characteristics of urban architecture. Antique buildings refer to buildings that are specially used to imitate and replace ancient buildings, traditional landscaping, historical buildings, cultural relics buildings, ancient villages, etc., to restore the historical style and appearance.

[0003] The characteristics of Chinese antique buildings can be summarized in four sentences, namely: large roof, wooden frame, eaves decoration, and stone base. A large roof refers to a large vertical height of the roof, a steep slope, steep eaves, and a wide eaves extension. Therefore, the design of large antique buildings today is diverse, especially the roof shape is more diverse, mostly with large-area curved structures. Among them, the diversity of roof curves, as well as the connection of curves, the transition of curvature, beam-column joints, and beam-beam joints are difficult to construct.

[0004] like Figure 1 As shown in the figure, the antique building roof is designed as a large-span variable curvature double-arc goose-shaped roof structure. The span of this arc structure is more than tens of meters. In traditional construction, the construction workers rely on their experience to control the elevation of the ends and the middle of each line of the roof based on the ground elevation. However, the overall elevation and curve cannot be accurately controlled, resulting in the subsequent roof structure failing to meet the design requirements. This in turn affects the decoration construction, and more costs are required to deal with the roof base problem. Summary of the invention

[0005] The invention solves the problem of construction of large-span arched roofs of antique buildings and provides an integrated construction method for an antique building variable-curvature double-arc goose-shaped roof.

[0006] The technical solution to realize the present invention is a method for integrally building a variable curvature double-arc goose-shaped roof of an antique building, the steps of which are: Set up a full-floor scaffolding, install the arc structure curvature control tool on the adjustable support on the upper part of the frame, install the roof formwork and beam formwork on the arc structure curvature control tool at the bottom, pour concrete, and then use the extra-long arc structure concrete arc ruler to perform arc processing and inspection on the roof and beam upper surface.

[0007] Furthermore, the full-floor scaffolding includes a roof supporting frame and a beam supporting frame. A number of adjustable supports are provided on the top of the frame. The overall curvature is determined by adjusting the extended length of the adjustable supports, and the curvature of the bottom form is adjusted by the arc structure curvature control tool so that the overall curvature meets the design requirements, reflecting the arc-shaped goose-shaped roof structure.

[0008] The present invention adjusts the formwork support system to achieve the combination of the curve direction when designing the formwork system, which can meet both the formwork support function and the curve control. In addition to combining the formwork system with the curve in the design stage, the integrated roof construction described in the present invention also takes corresponding measures to control the concrete thickness and surface concrete elevation before pouring the concrete. The application of the above construction method makes the integrated roof construction have a good forming curve, creates better construction conditions for the surface layer construction, and improves the efficiency and quality of subsequent construction.

DETAILED DESCRIPTION

[0011] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of the integrated construction method of the variable curvature double-arc goose-shaped roof of an antique building of the present invention in conjunction with the accompanying drawings.

[0012] like Figure 1 to Figure 11 As shown, a construction method for an integrated construction of a variable curvature double-arc goose-shaped roof of an antique building comprises the following steps: Set up a full-floor scaffolding, install the arc structure curvature control tool 8 on the adjustable support 3 on the upper part of the frame, install the roof formwork 6 and the beam formwork 61 on the arc structure curvature control tool 8 at the bottom, pour concrete, and then use the extra-long arc structure concrete arc ruler 9 to perform arc processing and inspection on the upper surface of the roof 7 and the roof beam 71.

[0013] The full-floor scaffolding includes a roof support frame and a beam support frame. A number of adjustable supports 3 are provided on the frame. The overall curvature is determined by adjusting the extended length of the adjustable supports 3, and then the curvature of the bottom mold is adjusted with the arc structure curvature control tool 8 to make the overall curvature meet the design requirements, reflecting the arc-shaped goose-shaped roof structure.

[0014] The raw materials for the construction of the support system include flexible multilayer panels (12 mm), fastener-type steel pipe scaffolding, adjustable supports 3, arc structure curvature control tools 8 and extra-long arc structure concrete arc rulers 9.

[0015] The detailed steps include: 1. Use BIM technology to draw the roof and beam-slab model, design the formwork system based on the model, and control the distance between the steel pipe support points and the primary and secondary keels to ensure the stability of the support system and make the roof curve smooth.

[0016] 2. Select the appropriate template according to the cross-sectional dimensions of the roof beam.

[0017] The cross section of the roof beam 71 is mostly 400*800, the template uses 12mm, flexible multilayer board, the template needs to be cut into 400*1800, the long side is along the curve direction, the flexible multilayer board has good bending performance and can meet the requirements of the roof curve. The template support uses the arc structure curvature control tool 8 to accurately control the curvature of the flexible multilayer board.

[0018] 3. Roof panel 7 uses 450*1800 templates, with the short side parallel to the curve direction. To ensure the smoothness of the curve, the template parallel to the curve direction needs to be spliced ​​with narrow sides. Using the arc differential principle, the more line segments there are between two points of the arc, the closer the arc is to a circle.

[0019] 4. According to the elevation of the design drawing, the extension length is adjusted by the adjustable support 3 and the roof curve is controlled in combination with the arc structure curvature control tool 8. The roof panel 7 is provided with support stirrups, and the elevation control line is set at the upper end of the steel bar. Using the principle of elliptical arc, the ultra-long arc structure concrete arc ruler 9 is used to control the thickness of the roof concrete and the curvature of the roof structure.

[0020] 5. By controlling the slump of concrete and pouring from the bottom of the slope to the top of the slope, the stirrup steel bars can not only control the elevation of the curve, but also play a certain role in hanging concrete.

[0021] like Figure 8 As shown, the arc structure curvature control tool 8 is used to accurately control the curvature of the flexible multilayer board after the frame is erected. The tool uses the arc differential principle, and there is an arc adjustable telescopic device on the support. The crank 81 of the tool is used to control the curvature of the multilayer board and the keel.

[0022] like Fig. 9 As shown, the super-long arc-shaped structural concrete arc ruler 9 is used to accurately control the curvature of the roof when pouring the surface concrete. The tool uses the principle of ellipse, and there is a retractable connecting rod at the handle to control the distance between the two foci of the ellipse. The foci are connected to the retractable support rod to control the radius of the ellipse arc. There is an arc-shaped retractable device between the support rods to control the curvature of the arc.

[0023] Before using the arc structure curvature control tool, the curvature of each structural member should be calculated, and the tool curvature should be adjusted accordingly. The adjustable support should be used to adjust the extension length for curvature control.

[0024] Before pouring concrete, check the elevation control points of the stirrup reinforcement. When using the extra-long arc structure concrete arc ruler, strictly control the arc of the area according to the elevation control points.

[0025] Construction workers must be able to operate the above tools skillfully and use them in combination, from scaffolding erection to formwork support to concrete pouring. Corresponding measures and tools should be used in conjunction with each process to ensure that the curvature of the roof is well controlled, avoiding subsequent repairs and increased costs.

[0026] The application of this method not only successfully solved the problems of curvature and node construction difficulties in the main roof construction, but also successfully solved the subsequent repair costs, achieving one-time construction, saving costs, and achieving good social and economic benefits.

[0027] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
