Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly relates to an imitation ancient building wing angle and a construction method thereof. Background Art

[0002] An imitation ancient building refers to a building that uses modern technical means to imitate the form of ancient buildings. Among them, the imitation of the wing angle part of ancient buildings is relatively difficult. The wing angle of ancient buildings is a typical structure at the corner of the eaves, used at the connection of the eaves of two adjacent slopes of the roof, located at the corner of the building, and is generally assembled by wooden structures such as corner beams, pillow woods, and rafters. It is an important part of ancient buildings.

[0003] The wing angle of ancient buildings is extremely complex. The gradually changing lengths and inclination angles of the cornice boards and continuous eaves need to be precisely calculated, and the sizes of each component also have certain specifications. Therefore, it is necessary to accurately grasp the sizes of each component during the process of imitating ancient buildings. Currently, for complex structures, the general imitation method is to set up a formwork according to the shape of the ancient building from the external perspective, pour concrete into the formwork, and let the concrete solidify into the same shape as the ancient building. Then, paint is applied to simulate the effect of wood, so that it looks like it is composed of wood splicing from the external perspective.

[0004] In order to present a flying and lively charm and add upward movement to the building, the wing angle of ancient buildings often has a large number of curves. For ancient buildings, the curves are composed of multiple pieces of wood spliced together. If an imitation ancient building is prefabricated in a factory and then spliced together in the way of ancient buildings, it will greatly increase the construction time and cost, and the requirements for construction technology are extremely high. If the commonly used method of directly setting up a formwork and pouring in the prior art is adopted, problems such as difficult control of the formwork setting angle and elevation will be faced, and the existing formwork is difficult to simulate the cornice rafters with continuously changing width and height in ancient buildings; resulting in a large difference between the final product and the real ancient building, and fine repair will bring a long construction period.

[0005] Therefore, there is an urgent need for an imitation ancient building wing angle and a construction method thereof with simple construction technology, short construction period, and high restoration degree. Summary of the Invention

[0006] The purpose of the present application is to solve the problem that it is difficult to imitate the wing angles of ancient architecture in the prior art. Therefore, the present invention provides a wing angle of ancient architecture and its construction method, which disassembles the complex structure of ancient architecture into: a cornice slab cast by concrete and a wooden angle beam and flying eave prefabricated in a factory, and finally splices the two to imitate the shape of ancient architecture; in the concrete casting part, the continuous eaves purlins and flying eaves in the original ancient architecture are split into multiple sections, and formwork is respectively erected for casting, and finally the height and width differences between the sections are leveled by a leveling layer to form continuous eaves purlins. The problems of difficult control of width and height in a continuous structure and the need to customize large-sized formwork are solved; the construction efficiency is improved and the construction cost is reduced.

[0007] To achieve the above object, in the first aspect, the present invention provides a wing angle of ancient architecture, which is arranged on two vertically arranged frame beams forming a corner, and includes a cast-in-place component and a prefabricated component;

[0008] The cast-in-place component includes a cornice slab;

[0009] There are two cornice slabs, which are respectively arranged on the sides of the two frame beams, and extend along the sides of the frame beams and converge at the corner of the two frame beams;

[0010] When the two cornice slabs converge towards the corner of the frame beam, the height continuously increases and the width extending outwards continuously increases;

[0011] The starting point of the height increase of the cornice slab is the upturn point, the height of the cornice slab relative to the upturn point is the upturn height, and the planar distance of the cornice slab from the frame beam is the overhang width;

[0012] The prefabricated component includes a prefabricated flying eave and an angle beam;

[0013] There are multiple flying eaves, which are arranged horizontally at intervals under the cornice slab, and the old angle beam is arranged under the convergence position of the two cornice slabs.

[0014] The complex structures such as angle beams, purlins, continuous eaves and pillow wood pads in ancient architecture are simplified into a cornice slab formed by concrete casting and flying eaves and angle beams prefabricated in a factory. After the cornice slab is completed by concrete casting, the flying eaves and angle beams are installed under the cornice slab to form the appearance of ancient architecture. Since the obvious flying eaves and angle beams exposed outside are all prefabricated in the factory, the overall reduction degree of the wing angle of ancient architecture is high; and the construction is simple and convenient.

[0015] In some embodiments, the cornice slab extends outwards in two layers, and the overhang width of the upper cornice slab is greater than that of the lower cornice slab;

[0016] The flying eaves are arranged under the upper cornice slab, and a warped flying eave is correspondingly arranged under the lower cornice slab.

[0017] Some ancient building wing corners have two layers, including the large eaves purlin and the small eaves purlin. Adopting the above technical solution, when pouring the cantilever slab, multiple supporting formworks can also be used to make a double-layer cantilever slab, restoring the two-layer large eaves purlin and small eaves purlin.

[0018] In some embodiments,

[0019] The angled beam and the cornice are prefabricated from wood. Adopting the above technical solution, real wood can increase the aesthetic degree of the antique building, and the angled beam and cornice prefabricated by the factory according to the design drawings have little impact on the construction period and are inexpensive, and can achieve effects such as fan-shaped rafter layout and beveled end surfaces.

[0020] In some embodiments, the angled beam includes an old angled beam and a young angled beam that extend outward from the frame beam and are arranged in sequence, and the distal end of the young angled beam extends to the edge of the cantilever slab.

[0021] Adopting the above technical solution, the segmented angled beam in the ancient building is restored.

[0022] Second, the present application also provides a construction method for the wing corner of an antique building. For the above-mentioned wing corner of the antique building, its steps include:

[0023] S1. Draw the drawings of the ancient building according to the requirements, and determine the warping height and punching height at each position of the cantilever slab;

[0024] S2. Along the direction perpendicular to the frame beam, divide the continuous cantilever slab in the drawings of the ancient building into multiple segments;

[0025] S3. By making a sectional view, determine the warping height and punching width at the segmentation of the cantilever slab; use the warping height and punching width at the segmentation as the warping height and punching width of the subsequent section of the cantilever slab to form the cantilever slab of the antique building, and the cantilever slab in the antique building is in a stepped shape;

[0026] S4. Horizontally support a leveling formwork under the cantilever slab;

[0027] S5. Lay out the cantilever slab in the antique building on the leveling formwork, and mark the vertical projection of each section of the cantilever slab;

[0028] S6. Set up a vertical elevation control board on the leveling formwork;

[0029] S7. Lay out the warping height of the cantilever slab in the antique building on the elevation control board, and mark the horizontal projection of each section of the eaves purlin board;

[0030] S8. Set up the side formwork on the leveling formwork according to the lofting line, and form the shape of the cornice board in the antique building through the side formwork;

[0031] S9. Set the steel bars in the formwork and pour the concrete;

[0032] S10. After the concrete solidifies, remove the formwork, and fill the height difference and length difference between the cornice boards of each section with a mortar leveling layer, so that the cornice board forms a continuous curve, and complete the construction of the cornice board;

[0033] S11. Set the flying eaves and the corner beams under the cornice board according to the ancient building drawings to complete the construction of the wing angles of the antique building.

[0034] Adopting the above technical solution, the continuous cornice board is divided into multiple sections through the ancient building drawings, the formwork is set up section by section, and finally it is leveled through the leveling layer, realizing the pouring of the curved cornice board, without the need to customize large formwork, saving construction costs, and the size and shape of the cornice board are easier to control and the restoration degree is higher.

[0035] In some embodiments, in step S8, the side formwork is set according to the lines placed on the leveling formwork and the elevation control board, and a wooden square is arranged below the side formwork, and the wooden square pads and supports the side formwork to the design elevation.

[0036] Adopting the above solution, the formwork is supported by the wooden square to keep the formwork at a stable angle and height.

[0037] In some embodiments, the height of the leveling formwork is determined according to the upturn point, and a support is arranged below it for support;

[0038] The position of the elevation control board is set according to the projection of the cornice board on the leveling formwork.

[0039] Adopting the above solution, the leveling formwork is set to provide an operating surface for the formwork of the upturned part of the wing angle.

[0040] In some embodiments, in step S9, the quantity and type of the steel bars are calculated according to the specifications, and the steel bars include the top reinforcement of the cornice board at the upper part, the bottom reinforcement of the cornice board at the lower part and the distribution reinforcement of the cornice.

[0041] Adopting the above solution, the strength of the cornice board is increased by the steel bars.

[0042] In some embodiments, the cornice board is segmented according to the position of the flying eaves in the ancient building, and one section is between two adjacent flying eaves.

[0043] Adopting the above solution, the segmentation is clearer and more convenient.

[0044] In some embodiments, the steel bars in the frame beam penetrate a certain distance and extend into the cornice slab, and are cast integrally with the cornice slab.

[0045] Adopting the above solution increases the fixing strength of the cornice slab.

[0046] Generally speaking, compared with the prior art, the beneficial effects of the present invention are as follows: by dividing the wing angles of ancient buildings into cast-in-place parts and precast parts, and by splitting the continuous cornice slabs in ancient buildings into multiple segments and setting up formworks for each segment separately, the restoration degree is higher and the cost is lower. Finally, the overhanging eaves and corner beams prefabricated in the factory are fixed on the lower side of the cornice slab, realizing the simulation of the appearance of ancient buildings and making the imitation ancient buildings have a higher similarity.

[0047] Other features and corresponding beneficial effects of the present application are described in the following part of the specification, and it should be understood that at least some of the beneficial effects are obvious from the description in the specification of the present application.

[0059] Embodiment

[0060] See Figures 1 to 5 , this embodiment provides an imitation ancient building wing angle and its construction method. In the imitation ancient building wing angle, the wing angle is arranged on two vertically arranged frame beams 1 that form a corner, and includes a cast-in-place component and a prefabricated component;

[0061] The cast-in-place component includes a cornice board 2; it is made by cast-in-place concrete.

[0062] There are two cornice boards 2, which are respectively arranged on the sides of the two frame beams 1, and extend along the sides of the frame beams 1 and converge at the corner of the two frame beams 1;

[0063] When the two cornice boards 2 converge at the corner of the frame beam 1, the height continuously increases and the width extending outward continuously increases;

[0064] The starting point of the height increase of the cornice board 2 is the upwarping point 11. The height of the cornice board 2 relative to the upwarping point 11 is the upwarping height, and the planar distance between the cornice board 2 and the frame beam 1 is the overhanging width;

[0065] The prefabricated components include a prefabricated cornice 3 and a corner beam 4, which are prefabricated from wood. The corner beam 4 includes an old corner beam 41 and a young corner beam 42. The outer sides of the two eaves boards 2 converge at the distal end of the young corner beam 42.

[0066] There are multiple cornices 3, which are arranged horizontally and spaced apart under the eaves board 2. The old corner beam 41 is arranged under the converging position of the two eaves boards 2.

[0067] The wing angles in ancient buildings are composed of multiple pieces of wood assembled by mortise and tenon joints. Considering construction efficiency and cost, it is impossible to completely follow the construction method of ancient buildings in imitation ancient buildings. Generally, concrete pouring is used to imitate the appearance of each structure in ancient buildings. Since there are certain standard requirements for the sizes of each structure in ancient buildings, how to set up the formwork to make the structure after pouring more conform to the actual situation of ancient buildings while also controlling the construction cost. In this embodiment, the wing angles in the entire ancient building are split into the concrete-poured eaves board 2 and the prefabricated cornice 3, taking into account the actual cost and construction efficiency as well as the simulation degree. The wing angles of the imitation ancient building not only have a real wooden cornice 3, making it look more realistic, but also have an eaves board 2 completely composed of concrete pouring, with low construction cost and high efficiency.

[0068] Specifically, in the imitation ancient building, the eaves board 2 extends outward in two layers, and the overhanging width of the upper eaves board 212 is greater than that of the lower eaves board 222.

[0069] The cornice 3 is arranged under the upper eaves board 21, and a warped cornice 31 is correspondingly arranged under the lower eaves board 22. After the construction of the eaves board 2 is completed, the cornice 3 and the warped cornice 31 are installed by bolts.

[0070] This embodiment also provides a construction method for the wing angles of an imitation ancient building. For the above-mentioned wing angles of the imitation ancient building, the steps include:

[0071] S1. Draw the drawings of the ancient building according to the requirements and determine the warping height and overhanging height at each position of the eaves board 2.

[0072] S2. Along the direction perpendicular to the frame beam 1, divide the continuous eaves board 2 in the drawings of the ancient building into multiple segments.

[0073] S3. By making sectional views, determine the warping height and overhanging width at the segmented position of the eaves board 2; take the warping height and overhanging width at the segmented position as the warping height and overhanging width of the subsequent section of the eaves board 2 to form the eaves board 2 of the imitation ancient building. The eaves board 2 in the imitation ancient building is in a stepped shape.

[0074] S4. Horizontally set up a leveling formwork 5 under the eaves board 2.

[0075] S5. Lay out the eaves board 2 in the antique building on the leveling formwork 5, and mark the vertical projection of each section of the eaves board 2.

[0076] S6. Set up a vertical elevation control board 6 on the leveling formwork 5.

[0077] S7. Lay out the pattern on the elevation control board 6 according to the upturned height of the eaves board 2 in the antique building, and mark the horizontal projection of each section of the continuous eaves board.

[0078] S8. Support the formwork on the leveling formwork 5 according to the layout line, and form the shape of the eaves board 2 in the antique building through the formwork.

[0079] S9. Set the steel bars 10 inside the formwork and pour concrete.

[0080] S10. After the concrete solidifies, remove the formwork, and fill the height difference and length difference between each section of the eaves board 2 with a mortar leveling layer, so that the eaves board 2 forms a continuous curve, and complete the construction of the eaves board 2.

[0081] S11. Set the flying eaves 3 and the old corner beam 41 under the eaves board 2 according to the ancient building drawings to complete the construction of the wing corner of the antique building.

[0082] Specifically, in step S8, the side formwork 7 is set according to the lines drawn on the leveling formwork 5 and the elevation control formwork. There is a wooden square 8 under the side formwork 7, and the wooden square 8 pads and supports the side formwork 7 to the design elevation.

[0083] Specifically, the height of the leveling formwork 5 is determined according to the upturned point 11, and there is a support 9 under it for support.

[0084] The position of the elevation control board 6 is set according to the projection of the eaves board 2 on the leveling formwork 5.

[0085] Specifically, in step S9, the quantity and type of the steel bars 10 are calculated according to the specifications. The steel bars 10 include the top reinforcement of the eaves board 2, the bottom reinforcement of the eaves board 2 and the distribution reinforcement of the eaves board.

[0086] Specifically, the eaves board 2 is segmented according to the position of the flying eaves in the ancient building, and each section is between two adjacent flying eaves 3.

[0087] Specifically, the steel bars 10 in the frame beam 1 extend a certain distance and extend into the eaves board 2 to be cast and formed together with the eaves board 2.

[0088] The cantilever slab 2 in the ancient building is a whole continuously curved slab, which has variable curves in both height and width. If the formwork is directly set up according to the ideas in the existing technology, the conventional formwork cannot be set up into a continuous curved shape, and a large formwork needs to be specially customized according to the shape of the cantilever slab 2. This kind of customized formwork has a high cost and a long production cycle and cannot be reused. However, in the solution of this embodiment, according to the design drawings of the ancient building, the cantilever slab 2 is divided into multiple segments, the formwork is set up in segments, and after pouring, leveling is carried out through the leveling layer to achieve a continuous curve, and the construction cost is lower.

[0089] Those skilled in the art should understand that those skilled in the art can implement the variations in combination with the existing technology and the above embodiments, which will not be elaborated here. Such variations do not affect the essence of the present invention and will not be elaborated here.

[0090] The preferred embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific implementation manners, and the equipment and structures not described in detail should be understood to be implemented in the ordinary manner in the art; any person skilled in the art, without departing from the scope of the technical solution of the present invention, can make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above, or modify it into an equivalent embodiment with equivalent changes, which does not affect the essence of the present invention.
