Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sloping roof construction, and in particular to a circular arc sloping roof reinforcement structure system and a construction method for the construction of ultra-long special-shaped buildings. Background Art
[0002] Many natural landscapes are great tourist destinations, but the more spectacular the natural landscape, the more remote and inhospitable the transportation and geological environment. Take a waterfall as an example. The waterfall is located in a river section with a huge drop in height. At the same time, the river flow rate is extremely high, which causes severe water erosion and undercutting of the strata. This makes the river bank very narrow, and the land available for the construction of viewing buildings is a long and narrow strip, a considerable part of which is also a floodplain. This makes it difficult to build permanent buildings in this area. Taking the Hukou Waterfall Scenic Area Construction Project involved in the present invention as an example, according to actual geological surveys and construction experience, there are the following difficulties in building permanent buildings on such a river bank: 1. Weak foundation According to drilling revelations, the foundation soil of the site is mainly composed of recently accumulated miscellaneous fill (Q4ml), silt (Q4al+pl) and Permian (P) sedimentary rocks, and the rock types are mainly sandstone, muddy sandstone, mudstone, sandstone, etc.
[0003] Silt, as a bearing layer, not only causes uncontrollable settlement and deformation, preventing a secure bond with piles, but also poses a risk of liquefaction when submerged in water. Furthermore, argillaceous sandstone and mudstone have very low strength and are easily deformed or damaged (thus damaging piles on the bedrock or compressing or stretching the foundation). Given that silt, argillaceous sandstone, and mudstone are all inevitable river sediments, the problem of weak foundations is unavoidable whenever permanent structures are constructed on such riverbanks.
[0004] 2. Extremely easy to overturn and difficult to resist earthquakes Due to land restrictions, the building must be constructed in a very long strip, and the aspect ratio will far exceed the usual convention of 1.5:1. This makes it a seriously overlong type among "slab buildings" and prone to overturning along the short side. At the same time, the excessive aspect ratio makes the building's torsional stiffness and short side stiffness extremely poor, making it easy to collapse in an earthquake due to insufficient stiffness.
[0005] Therefore, the present invention adopts an extra-long special-shaped building that can adapt to narrow riverbeds with unstable soil layers. It adopts specially shaped arc-shaped sloping roofs and inclined columns. When constructing the arc-shaped sloping roof, the beams around the arc-shaped sloping roof are arc-shaped sloping beams. The arc-shaped sloping beams and inclined column structural components are over-limit components, which are difficult to construct and have great safety risks and quality hazards. If the conventional standardized steel formwork + I-beam support system is used, reinforcement is difficult and the cost is too high. In addition, public buildings have no standard floors and cannot be turned around. Summary of the Invention

[0015] The present invention also provides a construction method for a circular arc sloping roof reinforcement structure system for ultra-long special-shaped building construction, comprising the following steps: S1. Measuring and setting out: The formwork support system for the inclined cylinders and inclined circular arc beams is located on the basement structure roof slab. Project the axes onto the ground according to the design drawings, mark them with ink lines, and mark the projected plane contour lines of the inclined cylinders and inclined circular arc beams with ink lines.

Erecting the support frames: Erect the inclined roof reinforcement support frames, inclined cylinder reinforcement support frames, and inclined beam support frames according to the positioning lines and calculated heights of the inclined cylinders and inclined circular arc beams, and respectively carry out the inclined cylinder reinforcement support inside the floor slab and the inclined cylinder reinforcement support at the outer edge of the floor slab. S3. Installing the formwork for pouring the inclined cylinders and reinforcing with steel belts: Lay the standardized round wood formwork on the inclined cylinder reinforcement support frames with adjusted heights.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The roof of the present invention uses an inclined roof that slopes obliquely downward from the first unit towards the upstream of the river. The inclined roof is a steel structure roof supported by columns. Among the columns supporting the inclined roof, the columns at the bottom of the inclined roof are reinforced concrete (heavier) inclined cylinders, and the tops of the inclined cylinders tilt towards the upstream of the river. By using a prestressed inclined roof in the first unit, the deformation of the foundation under the first unit will not cause the roof to deflect downward.
[0017] 2. The support positions of the inclined roof casting formwork and the inclined column casting formwork are adjusted respectively through adjustable frame head supports, so that the structures of the inclined roof casting formwork and the inclined column casting formwork are stable, ensuring the casting forming quality of the inclined roof and the inclined column, and thus realizing the high-quality reinforcement treatment of the inclined roof. The frame head support is provided with a support limiting member with a bending structure and a limiting groove with an arc structure to respectively carry out stable support treatment for the double steel pipe and the single steel pipe, ensuring the stability of the overall structure and being easy to adjust the position.
[0018] 3. The inclined column reinforcement structure forms a stable inclined support by combining inclined vertical rods, horizontal rods with the support system, so as to more stably reinforce and support the inclined column formwork and ensure the forming quality of the inclined column.
[0019] 4. The inclined outer beam reinforcement structure of the inclined roof enables the outer inclined beam to be constructed on the basis of the inclined column. By reinforcing and supporting and adjusting the outer formwork and the bottom formwork, the overall pouring precision of the inclined arc beam is improved. The bottom formwork of the inclined arc beam and the outer formwork of the inclined arc beam are supported by the backstop rods, and a fastening plug is clamped in the backstop rods, which not only ensures the fastening of the connection between the fastening plug and the backstop rods, but also increases the supporting area of the backstop rods for the bottom formwork of the inclined arc beam and the outer formwork of the inclined arc beam, ensuring the structural stability of the bottom formwork of the inclined arc beam and the outer formwork of the inclined arc beam.

DETAILED DESCRIPTION OF THE INVENTION
[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0022] Embodiment 1: The project of this embodiment takes an ultra-long special-shaped building as an example. This ultra-long special-shaped building is adapted to the narrow river beach with unstable soil layers. The tower of the ultra-long special-shaped building is in a broken line shape and extends along the river bank. The podium is filled in the notch of the broken line. Each section of the tower is an integrated unit, and a structural joint is provided between adjacent tower units. The purpose of doing this is to reduce the aspect ratio of the foundation and the overall aspect ratio of the building without changing the actual length of the tower, thereby enhancing the stiffness and torsional stiffness of the building in the short direction. In view of the lack of a clear definition of the river bank, the river bank in this article refers to the area between the natural levee of the river and the valley slope of the river valley.
[0023] In each section of the tower unit, they are arranged in sequence from top to bottom along the river flow direction. The frontmost one is denoted as the first unit. The roof of the first unit has prestress parallel to the extension direction of this section of the tower unit and of the tensile stress type. For a building on a soft and narrow river beach, in addition to the influence of the strata under the building, the influence of the strata in the upstream and downstream directions of the river also needs to be considered (the bedrock strength is low and the soil is soft). The strata in the upstream direction tend to slip / compress downward. Even with a retaining wall blocking, it cannot be completely avoided. The foundation of the first unit will be shortened accordingly, driving the roof to deflect downward. Here, prestress tension is carried out on the roof in advance to offset the tendency of the roof to shorten.
[0024] As Figure 1 shown, the prestress in the roof of the first unit 10 is applied by the following structure: The roof of the first unit 10 is an inclined roof 12 that slopes downward from the first unit in the upstream direction of the river. The inclined roof 12 is a steel structure roof supported by columns. Among the columns supporting the inclined roof 12, the column at the bottom of the inclined roof 12 is a reinforced concrete (heavier) inclined circular column 21, and the top of the inclined circular column 21 inclines in the upstream direction of the river. By using a prestressed inclined roof in the first unit, the deformation of the foundation under the first unit (the upstream soil and rock slide / compress downward, causing the foundation at this place to be compressed) will not drive the roof to deflect downward.
[0025] Here, it is very difficult to determine the prestress elongation amount of the roof of the first unit 10 because the deformation of the foundation is a dynamic process. Therefore, conventional means cannot be used to apply prestress. Here, the inclined circular column 21 and the inclined roof 12 are used to apply prestress, which can not only achieve dynamic adjustment but also will not gradually weaken with the passage of time (here the prestress is applied by gravity, and even if the foundation is compressed, it does not affect the prestress. Conventional prestress tension cannot overcome this problem).
[0026] As Figures 2 to 9 shown, for the construction requirements of this extra-long and irregular-shaped building, the present invention designs a reinforced structure system for the construction of an extra-long and irregular-shaped building, including: an inclined roof reinforcement structure, an inclined circular column reinforcement structure, and an inclined circular arc beam reinforcement structure.
[0027] Specifically, the inclined roof reinforcement structure includes an inclined roof casting formwork 1.

The inclined roof reinforcement support frame 11 includes multiple groups of vertically supporting uprights 15 and first supporting crossbars 17 that are evenly spaced. The vertically supporting uprights 15 are evenly spaced and connected by bolts to the mutually perpendicular first supporting crossbars 17. This structure forms a three-dimensional grid frame structure between the vertically supporting uprights 15 and the first supporting crossbars 17 to achieve the bottom support of the inclined roof casting formwork 1. Below the inclined roof casting formwork 1, there is a wooden square 14. Below the wooden square 14, there are mutually perpendicular first steel pipes 13. The first steel pipe 13 is a double steel pipe. The arrangement of the wooden squares 14 is that two wooden squares are nailed to a 300-mm-wide formwork as a group. And at the upper end of the supporting upright 15, there is a formwork top support 16 connected to the first steel pipe 13. A threaded connecting rod is welded to the outer side of the bottom of the formwork top support 16, and the threaded connecting rod is rotationally connected to the vertically supporting upright through a threaded structure for adjusting the position of the formwork top support 16 relative to the inclined roof casting formwork 1.
[0028] The inclined circular column reinforcement structure includes an inclined circular column casting formwork 2. Below the inclined roof casting formwork 1, there are multiple groups of inclined circular column casting formworks 2 with different inclination angles at intervals. The inclined circular column casting formwork 2 is formed by staggeredly splicing standardized semi-circular wooden formworks and is reinforced with a circular steel belt. Inside the inclined circular column casting formwork 2, an inclined circular column 21 is cast. On the lower side of the inclined surface of the inclined circular column casting formwork 2, there is an inclined circular column reinforcement support frame. The inclined circular column reinforcement support frame includes multiple groups of obliquely supporting uprights 23, second steel pipes 24, and second supporting crossbars 232 that are evenly spaced.

The second steel pipes 24 are arranged in contact with the inclined circular column casting formwork 2. There is a U-shaped top support 231 between the upper end of the obliquely supporting upright 23 and the second steel pipe 24. The obliquely supporting uprights 23 and the second supporting crossbars 232 form a three-dimensional grid frame structure, thus playing an oblique supporting role for the inclined circular column casting formwork 2 to achieve the casting support of the inclined circular column inside the inclined circular column casting formwork 2, and the inclined circular column cast inside the inclined circular column casting formwork 2 can play a role in supporting and reinforcing the inclined roof 12.

[0031] The inclined circular arc beam casting formwork 3 includes an inclined circular arc beam outer formwork 301, an inclined circular arc beam inner formwork 302, and an inclined circular arc beam bottom formwork 303. The inclined circular arc beam outer formwork 301 and the inclined circular arc beam inner formwork 302 are respectively provided on both sides of the inclined circular arc beam 31.

The inclined circular arc beam casting formwork 3 is set on the top of the inclined circular column casting formwork 2, and the end of the inclined circular arc beam casting formwork 3 is provided with an extension section extending to the inside of the top of the inclined circular column casting formwork 2. The inclined arc beam casting formwork 3 of this structure can be cast synchronously with the concrete by extending the extension section into the interior of the top of the inclined cylindrical formwork 1, which can improve the stability of the structure after the inclined cylindrical casting formwork is cast.

[0036] Embodiment 4: The present invention also provides a construction method for a circular arc inclined roof reinforcement structure system for the construction of an ultra-long special-shaped building, including the following steps: S1. Measuring and setting out: The formwork support system of the inclined cylinder and the inclined circular arc beam is located on the basement structure roof slab. According to the design drawings, the axes are projected onto the ground, marked with ink lines, and the projected plane contour lines of the inclined cylinder and the inclined circular arc beam are marked with ink lines; S2. Erecting the support frame: According to the positioning lines and calculated heights of the inclined cylinder and the inclined circular arc beam, an inclined roof reinforcement support frame, an inclined cylinder reinforcement support frame and an inclined beam support frame are erected, and the inclined cylinder reinforcement support inside the floor slab and the inclined cylinder reinforcement support at the outer edge of the floor slab are respectively carried out; S3. Installing the inclined cylinder casting formwork and reinforcing with steel belts: Lay a standardized round wood formwork on the inclined cylinder reinforcement support frame with adjusted height. When installing the formwork, the two formworks at the upper and lower joints of the formwork are staggered. The formwork assembly height is specifically determined on site according to the steel bar lapping height, and a vibrating port is reserved in the inclined cylinder casting formwork. The round wood formwork is reinforced with a circular steel belt; S4. Installing the inclined circular arc beam casting formwork and the inclined roof casting formwork: Install the inclined circular arc beam bottom formwork, the inclined circular arc beam outer formwork and the inclined roof casting formwork on the inclined beam support frame with adjusted height. The inclined circular arc beam bottom formwork is cut according to the beam width and the beam radian. The inclined circular arc beam side formwork is assembled according to the beam height. After the inclined circular arc beam side formwork is fixed to the outer vertical wooden square, it is placed obliquely on the inclined beam support frame together with the reinforcing steel bars for assembly. The inclined circular arc beam steel bars are tied. After the inclined circular arc beam steel bars are tied, install the inclined circular arc beam inner formwork, and then use tie rods to tighten and fix the inclined circular arc beam side formwork through the reinforcing steel bars, and carry out the inclined roof steel bar tying; S5. Concrete pouring: Before pouring the inclined cylinder and the inclined circular arc beam, adjust the concrete mix ratio of the inclined cylinder and the inclined circular arc beam. Without changing the concrete strength, slump and design requirements, adjust the concrete mix ratio. After passing the tests and inspections, use the adjusted mix ratio concrete to pour the inclined cylinder and the inclined circular arc beam. First pour the inclined cylinder, and then pour the inclined circular arc beam. When pouring the concrete, pour it in layers and vibrate. When pouring the inclined circular arc beam, pour it from the middle to both sides.
[0037] Furthermore, when using the inclined cylinder reinforcement structure, first construct the base layer 212 at the bottom of the inclined cylinder pouring formwork 2. Then, insert steel bars around the inclined cylinder pouring formwork 2 through the base layer 212 to form a circular ring shape. At the same time, after sealing the inclined cylinder pouring formwork 2, use several steel belts 211 for reinforcement and erect the arc beam slab. At this time, under the bottom formwork of the inclined cylinder pouring formwork 2, a support system can be formed by erecting horizontal support bars and vertical support columns 15. During the erection of the horizontal support bars and vertical support columns 15, several inclined support columns 23 are synchronously arranged to support the bottom formwork of the inclined cylinder pouring formwork 2. When installing the inclined support columns 23, press the U-shaped top support 231 against the bottom formwork of the inclined cylinder pouring formwork 2, insert the second steel pipe 24 and triangular cushion blocks for fixation, and then evenly fix the second support cross bar 232 to the inclined support columns 23 for reinforcement. When installing the inclined support columns 23, use vertical clamps and horizontal clamps to connect them in a staggered manner at the connection between the second support cross bar 232 and the inclined support columns 23. When the vertical clamps and horizontal clamps are connected, lock them with tie rods. At the same time, fix the densifying bar 18 to the vertical support column 15 using butt joints. At this time, the support system composed of the inclined support columns 23, the second support cross bar 232, and the vertical support column 15 can form a stable inclined support to firmly reinforce and support the inclined cylinder pouring formwork. During the process of pouring concrete into the inclined cylinder pouring formwork, the vibrating rod can be inserted through the reserved opening on the surface to vibrate the concrete, thus completing a series of work.
[0038] Further, when using the inclined circular arc beam reinforcement structure, first embed the inclined beam embedded steel bar 304 in the inclined circular column 21. After the concrete reaches the construction strength after the inclined circular column 21 is poured, build an inclined beam support frame with a three-dimensional grid structure between the inclined circular columns 21. Then, put the inclined beam steel bar ring 305 on the inclined beam embedded steel bar 304 and fix it by wire binding. Then, under the support of the inclined beam support frame, install and fix the inclined circular arc beam bottom formwork 303, the inclined circular arc beam outer formwork 301 and the inclined circular arc beam inner formwork 302. Next, set up vertical bottom formwork support rods 342 under the inclined circular arc beam bottom formwork 303, and make the bottom formwork support rods 342 supported by the back-driving rods 343. Then, set up the outer formwork support inclined rods 341 on the side of the inclined circular arc beam outer formwork 301, and also support them by the back-driving rods 343. After that, fix the connecting crossbars 345 to between the outer formwork support inclined rods 341 and between the bottom formwork support rods 342 by means of bolts. Then, conduct elevation measurement. Adjust the back-driving rods 343 at the corresponding positions to make the back-driving rods 343 rotate and adjust relative to the outer formwork support inclined rods 341 and the bottom formwork support rods 342 through the connecting screws, and snap the fastening plugs 344 into the U-shaped structure of the back-driving rods 343 to fasten the back-driving rods 343 with the outer formwork support inclined rods 341 and the bottom formwork support rods 342, improving the stability of the support of the outer formwork support inclined rods 341 and the bottom formwork support rods 342. After completing the construction of the inclined circular arc beam reinforcement structure, conduct the pouring treatment of the inclined circular arc beam. After the inclined circular arc beam is poured, the construction of the inclined roof 12 can be carried out, thus completing a series of work.
[0039] Furthermore, when using the sloping roof reinforcement structure, first calculate the length of each section of the vertical support pole 15 according to the elevation on each contour line, and connect the vertical support poles 15 with relatively vertically arranged first support cross bars 17 at intervals by bolting, so as to form a three-dimensional grid support frame. The frame top support 16 is fixed to the upper end of the vertical support pole 15 by a threaded connecting rod, and the supporting position of the frame top support 16 is adjusted according to the elevation, and then two first steel pipes 13 are spaced above the vertical support pole 15. The first steel pipe 13 is clamped and positioned by the frame top support and the fastening plug, and then the wooden squares 14 are arranged along the contour lines and the diagonal lines. The wooden squares 14 are laid on the first steel pipes 13, and then the sloping roof casting template 1 is laid on the wooden squares 14 and fixed with nails. When laying the arc segment sloping roof casting template 1, first place the sloping roof casting template 1 on the wooden square 14, bend the template according to the adjusted wooden square 14 elevation until the curvature and elevation of the template meet the design requirements, and then use nails to fix the sloping roof casting template 1 to the wooden square at the bottom, and then fix the steel pipe and the wooden square with steel wire. After the sloping roof casting template 1 is laid and fixed, review the points on each contour line, adjust the frame top support 16 for the deviated points, and tighten the gap between the frame top support 16 and the support with a wooden wedge, and then clamp the vertical pole connecting rod with the positioning plate on the vertical support pole 15 at the adjacent position, and insert the pin for positioning. When constructing the inclined cylindrical casting formwork 2, the second steel pipe 24 used to support the inclined cylindrical casting formwork 2 is positioned and adjusted through the cooperation of the inclined support uprights 23 and the U-shaped top support 231, and then the second support cross bar 232 is fixed between the inclined support uprights 23 for reinforcement. After completing the construction of the reinforced structure, the inclined roof 12 and the inclined cylindrical 21 are cast, thereby completing a series of work.
