Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular to a large-span antique xie-shan roof structure. Background Art

[0002] The characteristic of the xie-shan roof is that the entire roof slopes inwards on all four sides. Among them, the triangular walls formed on both sides of the roof (i.e., the xie-shan roof) are the gables. The gables slope inwards to a position less than one bay inside the building, and there are no columns to support the inward-sloping part. The spatial relationship is complex, and the weight transfer of the entire gable and the roof is unclear.

[0003] For traditional wooden-structured xie-shan roofs, the craftsmanship is complex. Due to the limitations of wood materials and construction methods, the span of wooden-structured houses is relatively small. The weight of the roof is transmitted to the columns through layer-by-layer stacking, resulting in a top-heavy structure and being unfavorable for earthquake resistance. Moreover, the connection nodes are not reliable enough and become the weak points of the entire structure. In addition, the wooden structure is not the modern mainstream structure form. Professional teams are required for both design and construction, and the later maintenance and anti-corrosion costs are relatively high, and the service life is relatively short. Traditional wooden structures mostly adopt methods such as the method of laying beams horizontally, the method of chamfered beams, the method of gold columns (stepping on the golden hair), the method of fighting, etc., and the above methods are not applicable to modern mainstream steel-structured or reinforced concrete xie-shan roofs.

[0004] Chinese Patent CN207436259U discloses a steel-structured antique xie-shan roof building structure system, which uses mountain-shaped steel inclined beams to be erected on the top of steel columns through a connection node structure. The connection node structure includes four H-shaped steel bracket joints welded to the outer wall of the top of the column and arranged in a cross shape, thus realizing the construction of a xie-shan roof using a steel structure. However, in areas with high humidity such as scenic spots and mountainous areas, the steel structure has poor anti-corrosion and rust-proof capabilities and requires frequent maintenance. In addition, the appearance of the I-beam of the steel structure and the bolt joints conflict with the ancient building style and must be decorated and covered, which increases the difficulty of the later maintenance and anti-corrosion work of the steel structure. Summary of the Invention

[0005] Based on the above problems, the purpose of the present invention is to provide a large-span antique xie-shan roof structure to solve the problems such as small span, poor seismic performance, and poor corrosion resistance of the xie-shan roof in the prior art.

[0012] Preferably, the folded beam includes: a horizontal section and a slope section. Among them, the plane where the horizontal section is located is perpendicular to the plane where the second triangular roof truss is located, and the slope section forms a support beam for the gable roof. Further, the second cross beam is supported on the horizontal section of the folded beam.

For example, the intervals of the column on the beam and the folded beam can both be 5.25m.

[0016] Preferably, the first end of the folded beam can also be fixedly supported on the first cross beam in the first triangular roof truss. Specifically, it is fixedly connected by pouring with steel bars and cast-in-place concrete.

[0017] Preferably, the span of the hip roof structure is 5m to 32m. For example, the span of the hip roof structure can be 21m.

Among them, the first cross beam in the larger first triangular roof truss bears the tension generated by the inclined beam, so that the column does not bear the lateral force and only bears the vertical force, that is, the present invention uses the stability of the triangle to eliminate the horizontal thrust; while the weight of the smaller second triangular roof truss can be directly transmitted to the gable column through the folded beam (the folded beam serves as an intermediate support point), so that the structure has good seismic performance.

Specific implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention:

[0034] Figures 1-3 Schematically show the structures of the first triangular truss 10, the second triangular truss 20, and the folded beam 30 in the large-span antique xieshan roof structure of the present invention respectively.

[0035] The present invention provides a large-span antique xieshan roof structure, in which, the two sides of the xieshan roof form pediments, and a double-slope roof is formed between the two pediments. In the present invention, the double-slope roof is formed by a plurality of first triangular trusses 10 arranged in parallel as Figure 1 (the shaded part) shows, and the pediment is formed by the second triangular truss 20 as Figure 2 (the shaded part) shows; the xieshan roof structure further includes: a folded beam 30 in a broken line shape as Figure 3 shown, the first end of the folded beam 30 is supported on the first triangular truss 10, the second end is supported on the gable wall column 60 outside the pediment, and the second cross beam 22 of the second triangular truss 20 is supported on the folded beam 30; the inclined beam 11 and the first cross beam 12 in the first triangular truss 10 of the present invention, the inclined beam 11 and the second cross beam 22 in the second triangular truss 20, and the folded beam 30 are all steel-concrete beams or reinforced concrete beams. In the present invention, the span of the xieshan roof structure can be 5m to 32m.

[0036] Through the arrangement of the first triangular roof truss 10, the second triangular roof truss 20 and the folded beam 30, the force transmission of the hip roof structure is clear and reliable. Among them, the arrangement of the triangular roof truss not only meets the modeling requirements and reinforcement requirements, but also utilizes the stability of the triangle to eliminate the horizontal thrust, has good seismic performance, realizes the large-span form of the antique hip roof structure, and is made of a steel reinforced concrete beam or a reinforced concrete beam, making the structure corrosion-resistant and having a long service life.

[0037] In the present invention, the double-slope roof is formed by a plurality of first triangular roof trusses 10 arranged in parallel. As Figure 1 shown, the first triangular roof truss 10 includes: two inclined beams 11 connected in a V shape, and a first cross beam 12. Among them, the lower ends of the two inclined beams 11 are respectively fixed on two columns 50, and the first cross beam 12 is fixedly arranged between the two columns 50. The double-slope roof between the two gables adopts a larger triangular roof truss design, realizing a large-span double-slope roof. Among them, the first cross beam 12 bears the tension generated by the double-slope inclined beams 11, so that the columns 50 do not bear the lateral force and only bear the vertical force.

[0038] As an optional embodiment, when the span of the first triangular roof truss 10 is relatively large, a column on beam 40 as Figure 1 shown can be arranged in the first triangular roof truss 10 in combination with the building shape to reduce the cross-section of the inclined beam 11 and make its appearance closer to the light wood structure form. Specifically, the column on beam 40 is arranged vertically, with the top end fixed to the inclined beam 11 and the bottom end fixed to the first cross beam 12.

[0039] The gables on both sides of the top of the hip roof of the present invention are respectively formed by a second triangular roof truss 20, and the interior can be filled with blocks. As Figure 2 shown, the second triangular roof truss 20 includes: two inclined beams 11 connected in a V shape, and a second cross beam 22. Among them, the lower ends of the two inclined beams 11 are respectively fixed on two columns 50, and the second cross beam 22 is fixedly arranged between the two inclined beams 11, and the second cross beam 22 is higher than the first cross beam 12. The roof structure at the gable adopts a smaller triangular roof truss design, and the elevation of the second cross beam 22 is determined by the intersection point of the vertical ridge 72 and the hip rafter 73, that is, the height of the second cross beam 22 is the same as the height at the intersection point of the vertical ridge 72 and the hip rafter 73 in the hip roof structure. Due to the elevation of the second cross beam 22, the second triangular roof truss 20 is smaller than the first triangular roof truss 10. See as Figure 2As shown, the second crossbeam 22 is located above the first crossbeam 12. In the second triangular roof truss 20 of the present invention, the inclined beam 11 forms the vertical ridge 72 of the hip roof, the second triangular roof truss 20 bears the weight of the gable, the inclined beam 11 also bears the weight of the double-pitched roof, the second crossbeam 22 bears the weight of the gable slope roof (i.e., the single roof at the gable top), and the intersection of the second crossbeam 22 and the inclined beam 11 serves as the fulcrum of the hip rafter 73. The entire small roof truss forms the key points of the hip roof shape.

[0040] As an alternative embodiment, a column on beam 40 as shown in Figure 2 may also be provided inside the second triangular roof truss 20 to reduce the cross-section of the inclined beam 11 and make its appearance closer to a lightweight wooden structure form. Specifically, the column on beam 40 is vertically arranged, with its top fixed to the inclined beam 11 and its bottom fixed to the second crossbeam 22.

[0041] As shown in Figure 2 and Figure 3 In order to support the second triangular roof truss 20, the present invention also provides a folded beam 30 in a zigzag shape. Taking the folded beam 30 as the intermediate support point, the second triangular roof truss 20 can thus span the entire span of the house. As shown in Figure 3 The first end of the folded beam 30 is supported on the first triangular roof truss 10. Among them, the first end can be fixedly connected to the first crossbeam 12 by casting with steel bars and cast-in-place concrete, or directly fixedly connected to the column on beam 40; the second end of the folded beam 30 is supported on the gable column 60 outside the gable, and the second crossbeam 22 of the second triangular roof truss 20 is supported on the folded beam 30.

[0042] Preferably, as shown in Figure 3 the folded beam 30 may include a horizontal section and a slope section. Among them, the plane of the horizontal section is perpendicular to the plane where the second triangular roof truss 20 is located, and the slope section forms the support beam of the gable slope roof. Further, the second crossbeam 22 is supported on the horizontal section of the folded beam 30. It should be noted that the horizontal section can also be slightly inclined within a certain angle range. Among them, the slope section may only include a part between the gable column 60 and the second triangular roof truss 20, or may include a first slope section between the second triangular roof truss 20 and the gable column 60 and a second slope section extending outward from the gable column 60 (as shown in Figure 8 where the folded beam 30 is formed by three sections), and the second slope section extending outward from the gable column 60 can form an eaves, and the distance between the end and the gable column 60 can be 2m to 5m.

[0043] In the present invention, a plurality of folded beams 30 can be evenly arranged, and the interval is the same as the spacing of the gable columns 60. A plurality of columns on beam 40 can also be evenly arranged, and the interval can be 3m to 8m. Preferably, one folded beam 30 is correspondingly arranged on one column on beam 40.

[0044] The following describes the technical solution of the present invention in conjunction with an embodiment and Figures 4-9 is as follows:

[0045] A new cableway station building is built in a scenic area, which is a Chinese-style hip-and-gable imitation ancient building. As Figure 4 and Figures 6-9 shown, in the hip-and-gable roof structure, a ridge 71 is formed in the middle of the double-slope roof, the inclined beam 11 of the second triangular truss 20 forms a hip rafter 72, and the hip rafter 73 is connected to the hip rafter 72. As Figure 4 shown, the length of the building of the hip-and-gable roof structure (i.e., the distance between the wall columns 50 in the length direction) is 30 m. As Figure 5 shown, the span of the hip-and-gable roof structure (i.e., the distance between the two columns 50 in the width direction) is 21 m. Due to the long span of 21 m, the first cross beam 12 of the first triangular truss 10 adopts a steel reinforced concrete beam, and the others (such as the inclined beam 11 in the first triangular truss 10, the inclined beam 11 and the second cross beam 22 in the second triangular truss 20, and the folded beam 30, etc.) all adopt reinforced concrete beams. The steel reinforced concrete or reinforced concrete frame structure adopted by the hip-and-gable roof structure takes into account the advantages of concrete and steel structures. Although the construction is slightly complicated, it can make the structure have the advantages of large span, corrosion resistance, good seismic performance, and long service life.

[0046] As Figure 8 and Figure 9 shown, in the hip-and-gable roof structure, a first triangular truss 10 is arranged every 6 m, and a total of four are arranged side by side at intervals. In each first triangular truss 10, a column on beam 40 is arranged every 5.25 m, and a folded beam 30 is connected to each column on beam 40. As Figure 9 shown, the end of the folded beam 30 extends out of the outer side of the wall column 50 to form an eaves, and the distance between the extended part and the wall column 50 is 2200 mm, and the distance between the wall column 50 and the second triangular truss 20 is 1800 mm.

[0047] In this embodiment, the hip-and-gable roof shape formed by the first triangular truss 10, the second triangular truss 20, the column on beam 40, the folded beam 30, etc. can span a larger span compared with the prior art; the setting of the triangular truss and the folded beam 30 makes the force transmission of the hip-and-gable roof structure simple and reliable, meeting the seismic design principle of strong columns and weak beams; at the same time, the setting of the column on beam 40 reduces the cross section of the roof truss members, making its appearance closer to the light wooden structure form; in addition, the structure is made of steel reinforced concrete beams or reinforced concrete beams, having the advantages of good shaping effect, no column 50 is set inside the house, the use space is not affected, corrosion resistance, and long service life.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. The present invention includes all modifications, equivalents or replacements within the spirit and technical scope of the present invention.
