Description

Technical Field

[0001] This invention relates to the field of building engineering, specifically to a support system and method for constructing Gaussian curved fair-faced concrete in a coastal environment. Background Technology

[0002] Currently, in the construction of coastal Gaussian curved surface fair-faced concrete structures in China, coupler-type steel pipe support systems and steel support systems are generally used to ensure the stability of the curved components. Coupler-type ordinary steel pipe support systems tend to exacerbate corrosion of ordinary steel pipes during coastal construction, significantly impacting the rigidity of the pipes themselves, and the structural safety and stability still require improvement. Ordinary steel support systems, due to their excessive weight, are inconvenient to transport and install, negatively impacting construction progress and costs. Overall, the functionality, load-bearing capacity, safety and reliability, turnover rate, ease of installation, and cost reduction of support systems in the construction of coastal Gaussian curved surface fair-faced concrete structures all require further improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a formwork support system and method for constructing Gaussian curved surface fair-faced concrete in coastal environments. This solves the problems of material corrosion, inconvenient erection, and low safety and reliability in the construction of Gaussian curved surfaces in coastal projects, thereby increasing construction speed while reducing construction costs. This invention achieves its purpose through the following technical solutions:

[0004] A formwork support system for Gaussian curved fair-faced concrete construction in a coastal environment includes a socket-type disc-lock support frame and a fair-faced formwork wooden back brace system above it. The socket-type disc-lock support frame, as the main body of the support system, includes vertical uprights, horizontal crossbars, diagonal braces set on the vertical surface, and horizontal scissor braces. The uprights and crossbars are galvanized steel pipes, and the diagonal braces and horizontal scissor braces are fastener-type steel pipes. An adjustable top support is provided at the upper end of the uprights. The fair-faced formwork wooden back brace system includes a wooden I-beam as the main brace, an arc-shaped wooden back brace as the secondary brace, a panel, and... The lining plate and tie rods are provided; the wooden I-beam is placed on the upper part of the adjustable top support, and the arc-shaped wooden back rib is arranged at the upper end of the wooden I-beam along the direction of the Gaussian curved arch structure; a straightening block is provided in the gap between the wooden I-beam and the arc-shaped wooden back rib, and the straightening block is fixedly connected to the wooden I-beam; the lining plate is laid on the upper part of the arc-shaped wooden back rib, and the panel is laid on the upper part of the lining plate, and the panel and the lining plate are laid in a staggered manner; a sealing panel and wooden back rib are provided above the panel and reinforced by tie rods passing through the upper and lower panels.

[0005] Further optimizations include a 900mm span for the uprights, a 1500mm spacing for the horizontal bars, and diagonal bracing spaced every two bars. Vertical diagonal bracing is also installed in each span within the top-level spacing. The uprights are 500mm horizontally away from both sides of the arched wall, and horizontal scissor bracing is installed every four standard steps along the height direction.

[0006] Furthermore, the outer span of the plug-in disc buckle support frame serves as a protective frame for the support frame body. The span of the protective frame is 900mm, the step distance of the crossbars of the protective frame is 1500mm, and the upper side of each step is fully covered with hook iron plates. Protective railings are installed on both sides of the protective frame at 500mm and 1000mm of each step height, and safety nets are fully hung on the outer side.

[0007] Furthermore, a passageway for people is set at each end of the outer side of the protective frame. A 900mm pedestrian passageway is left between the passageway and the protective frame. The passageway is composed of disc-lock scaffolding combined with steel steps, hooks and iron plates. The entire outer side of the passageway is enclosed by safety netting.

[0008] Furthermore, the gap between the wooden I-beam and the curved wooden back rib is filled with a straightening block. The straightening block is cut to size according to the gap and is fixed to the wooden I-beam with nails. This ensures a tight connection between the main and secondary ribs and prevents deformation.

[0009] Furthermore, the curved wooden back ribs are manufactured using BIM technology, with each rib being custom-made by drawing and processing. They are made by cutting three 17mm thick templates according to the curvature and then nailing them together.

[0010] Furthermore, the preferred type of wooden beam is the H20 type; the H20 type wooden beam comes in three lengths of 1100mm, 2100mm, and 3000mm, ensuring that the wooden beam can be placed beyond the adjustable top supports at both ends.

[0011] A method for supporting formwork in the construction of Gaussian curved fair-faced concrete in a coastal environment, comprising the following steps:

[0012] Step 1: According to the construction drawings, lay out the positions of the uprights of the support frame. After the layout is completed, place a wooden pad in the center of the upright position, and place the upright on the wooden pad. The horizontal and diagonal bars are interlaced and placed, and the adjustable top support is placed on the top of the upright as the frame is erected. Horizontal scissor bracing is set up and reinforced after the main frame is erected. When connecting non-standard span arrays, steel pipes are used for tying. The support frame extends outward by one span from both ends of the arch roll as a protective frame for the frame. Access passages are set at both ends of the outer side of the protective frame. Safety nets are fully hung on both sides of the frame.

[0013] Step 2: Place a wooden beam in the middle of the adjustable top support, and fill the gap between the wooden beam and the two sides of the adjustable top support tray with wooden blocks; before placing the curved wooden back ribs on the frame, place the positioning ribs according to the layout positioning points.

[0014] Step 3: After determining the processing drawings using BIM technology, the curved wooden back ribs are precision-cut and shaped, and placed on the upper end of the I-beam according to the positioning ribs. The gap between the I-beam and the curved wooden back ribs is filled with a rotating block, which is then connected and fixed to the I-beam with nails. Before laying the panels, the rotating blocks are side-supported using a backing steel pipe and an adjustable backing base, and the backing steel pipe is connected and fixed to the uprights. Using BIM technology, the dimensions of the panels and backing boards are determined and a template drawing is created. The panels are precision-cut and shaped with bolt holes. The backing board is laid on the upper side of the curved wooden back ribs, and the panels are laid on top of the backing board with staggered joints to avoid grout leakage and deformation.

[0015] Step 4: Use BIM technology to determine the location of electromechanical points and place the embedded boxes according to the drawings. After the reinforcement of the arch roll structure is tied, use the panel and wooden backing to close the formwork on the upper side of the component. Then, use five-section tie rods to reinforce the arch roll.

[0016] Further optimization: In step two, before the curved wooden back ribs are placed on the frame, the positioning ribs are first placed according to the layout positioning points. The steel pipes are extended two spans inside and connected to the uprights with fasteners. One end of the steel pipe is cantilevered. The positioning ribs are then placed on the upper side of the steel pipes. The positioning ribs are to be embedded and fixed with the curved wooden back ribs.

[0017] The present invention relates to a formwork support system for Gaussian curved fair-faced concrete construction in coastal environments. Compared with the fastener-type steel pipe and wood formwork system, the socket-type disc buckle support frame combined with the fair-faced concrete formwork wooden back brace system provides better overall stability. The fair-faced concrete formwork combined with the wooden back brace system can adapt to fair-faced concrete components of various shapes. The present invention provides a new solution for the construction of Gaussian curved fair-faced concrete support frames, solving the technical difficulties in the construction of support frames for Gaussian curved fair-faced concrete structures in coastal areas. Compared with the conventional steel back brace system, the wooden back brace system also has the advantages of lower construction difficulty and faster construction speed.

[0018] Compared with the prior art, the features and beneficial effects of the present invention are as follows:

[0019] 1) The main rib of this invention uses a wooden I-beam in conjunction with a pivot block, which solves the problem of the main rib and secondary rib not being able to be tightly connected in an arc-shaped structure. The wooden I-beam itself, as the main rib, also has the advantages of high strength and structural stability.

[0020] 2) The present invention adopts a double-layer template structure of panel and backing plate. The panel and backing plate are laid in a staggered manner, which effectively avoids grout leakage. For the tie rod point area, the use of double-layer plate can also effectively avoid deformation, which plays an important role in the forming of Gaussian surface.

[0021] 3) This invention uses BIM technology to perform custom processing on curved wooden back ribs, templates, and tie rods, effectively saving materials and reducing the overall difficulty of construction.

[0022] 4) Compared with the fastener-type erection system, the present invention improves the stability of the frame, avoids the corrosion of steel pipe materials, and speeds up the construction progress.

[0023] 5) Compared with the steel back rib system, the present invention reduces the processing difficulty, reduces the construction cost, and speeds up the construction progress. Attached Figure Description

[0038] like Figure 1 , 2 As shown in Figure 3, the socket-type disc-lock support frame includes a vertical upright 1, a horizontal crossbar 2, vertically arranged diagonal braces 3, and horizontal scissor braces 4. The upright 1 and crossbar 2 are made of galvanized steel pipes, while the diagonal braces 3 and horizontal scissor braces 4 are made of fastener-type steel pipes.

The diagonal brace has a diameter of Ф42 and is made of Q235.

[0039] The outer span of the plug-in disc buckle support frame serves as a protective frame 22 supporting the frame body. The span of the protective frame 22 is 900mm, the step distance of the crossbars of the protective frame is 1500mm, and the upper side of each step is fully covered with hook iron plates 18. Protective railings are installed on both sides of the protective frame at a height of 500mm and 1000mm at each step, and safety nets 17 are fully hung on the outer side.

[0040] At each of the outer ends of the protective frame 22, there is a passageway 19 for people to enter. The passageway and the protective frame are connected by a 900mm pedestrian passage. The passageway 19 is composed of a combination of disc-lock scaffolding, steel steps, and hook plates 18. The outer side of the passageway 19 is completely enclosed by safety netting.

[0041] The clear water formwork wooden back rib system includes a wooden I-beam 9 as the main rib, an arc-shaped wooden back rib 5 as the secondary rib, a panel 6, a backing plate 7, and tie rods 8. The wooden I-beam 9 is placed on the upper part of an adjustable top support 15, and the arc-shaped wooden back rib 5 is arranged along the Gaussian curved surface arch construction direction at the upper end of the wooden I-beam 9. A centering block 10 is provided between the wooden I-beam 9 and the arc-shaped wooden back rib 5, and the centering block 10 is fixedly connected to the wooden I-beam 9. The backing plate 7 is laid on the upper part of the arc-shaped wooden back rib 5, and the panel 6 is laid on the upper part of the backing plate 7. The panel and the backing plate are laid in a staggered manner. A panel for sealing the formwork and a wooden back rib are provided above the panel 6 and reinforced by tie rods 8 (a five-segment tie rod is used in this embodiment) passing through the upper and lower panels.

[0042] The gap between the wooden I-beam 9 and the curved wooden back rib 5 is filled with a straightening block 10. The straightening block 10 is cut to size according to the gap and is connected and fixed to the wooden I-beam 9 with nails.

[0043] In this embodiment, the wooden beam 9 is an H20 wooden beam; the H20 wooden beam comes in three specifications with lengths of 1100mm, 2100mm, and 3000mm, ensuring that the wooden beam is placed beyond the adjustable top supports at both ends.

[0044] In this embodiment, panel 6 is made of 12mm thick poplar wood, with a panel size of 2400*1200. Backing board 7 is made of 15mm thick pine wood, with a backing board size of 2400*1200. Both the panel and backing board are precision-cut into blocks. Secondary ribs are 51*100 arc-shaped wooden backing boards. The arc-shaped wooden backing boards 5 are made of three 17mm thick templates nailed together and precision-cut into strips.

[0045] like Figure 1 , 2As shown in Figure 3, a Gaussian curved surface fair-faced concrete construction formwork support system in a coastal environment adopts a Gaussian curved surface fair-faced concrete construction process using a combination of disc-lock support frame and arc-shaped wooden back ribs 5. After the disc-lock frame is positioned and laid out, uprights 1 and horizontal bars 2 are arranged sequentially along the horizontal direction of the walls on both sides of the arch roll. During the horizontal erection of the uprights and horizontal bars, diagonal bars 3 are arranged in a way of alternating two and one. Adjustable top supports 15 are also placed synchronously with the erection of the frame. The uprights extend outward from both ends of the arch roll as a protective frame 22 for the frame, and access passages 19 are set at both ends.

[0046] like Figure 4 , 5 As shown in Figure 6, a wooden I-beam 9 is first placed in the center on the upper part of the adjustable top support 15 as the main beam. Ordinary steel pipes are used to connect the uprights for cantilevering. A positioning beam 11 is placed and fixed at the cantilever end. After the positioning beam is placed, an arc-shaped wooden back beam 5 is arranged horizontally along the arch structure direction. The fair-faced concrete construction formwork is laid in a staggered manner using a combination of panel 6 and lining plate 7. Finally, after the arch roll reinforcement is tied, the outside of the component is sealed with panel and wooden back beam. After the tie rod 8 is reinforced, the arch roll concrete is poured.

[0047] Example 2

[0048] Example 1: The construction of the formwork support system for the Gaussian curved fair-faced concrete in the mid-section includes the following steps:

[0049] Step 1: According to the construction drawings, lay out the positions of the support poles 1 500mm inward from the walls on both sides of the arch roll. All pole positions are laid out on the floor. After the layout is completed, place the wooden pad 14 in the center of the pole position, and then place the pole on the wooden pad.

[0050] Horizontal bars 2 and diagonal bars 3 are interspersed. The spacing between vertical bars 1 is 900mm, the step distance of horizontal bars is 1500mm, and the spacing of diagonal bars is one every two. Vertical diagonal bars are arranged in each span within the top step distance. Adjustable top supports 15 are placed on the top of the vertical bars as the frame is erected. Horizontal scissor braces 4 are set at every 4 standard step distances along the height direction of the support frame and are reinforced after the main frame is erected. When connecting non-standard span arrays, ordinary steel pipes are used for tying, and the tying points are coordinated with the arrangement of horizontal bars.

[0051] The support frame extends outward by one span at both ends of the arch roll to serve as the protective frame 22. On both sides of the protective frame, protective crossbars 2 are installed at 500mm and 1000mm heights of each step passage. Access passages 19 are set at both ends of the outer side of the protective frame. The access passages are connected to the protective frame with openings. The span of the protective frame is 900mm and the step distance is 2000mm. The upper side of each step is fully covered with hook iron plates 18 as a pedestrian passage for construction and acceptance. Safety nets 17 are fully hung on both sides of the frame.

[0052] Step 2: Install a safety net 20 within a 2-meter range of the top plate component, and place a wooden I-beam 9 in the middle of the adjustable top support 15. The gap between the H20 wooden I-beam and the two sides of the adjustable top support tray is filled with wooden blocks.

[0053] Before the curved wooden back rib 5 is placed on the frame, the positioning rib 11 is placed according to the layout positioning point. The ordinary steel pipe is extended two spans inside and connected to the upright of the disc buckle frame 1 with fasteners. One end of the steel pipe is cantilevered. The positioning rib 11 is then placed on the upper side of the ordinary steel pipe. The positioning rib 11 needs to be embedded and fixed with the curved wooden back rib 5.

[0054] Step 3: After determining the processing drawing using BIM technology, the curved wooden back rib 5 is cut into shape using a precision saw. According to the positioning rib 11, the curved wooden back rib 5 is placed on the upper end of the wooden I-beam 9. The gap between the wooden I-beam 9 and the curved wooden back rib 5 is filled with a straightening block 10. The straightening block 10 and the wooden I-beam 9 need to be connected and fixed with nails. Before the panel 6 is laid, the straightening block 10 is side-supported by the backing steel pipe 12 and the adjustable backing base 13. The backing steel pipe 12 is connected and fixed to the upright 1.

[0055] The upper template of the curved wooden back rib 5 is divided into a panel 6 and a backing board 7, both with a specification of 2400×1200. BIM technology is used to determine the size of the panel and the backing board and form a template drawing. The panel 6 is cut into shape by precision sawing and bolt holes are made. After processing, the backing board 7 is laid on the upper side of the curved wooden back rib 5. The panel 6 is laid on the backing board 7 and the joints are staggered to avoid grout leakage and deformation.

[0056] In this embodiment, after the arc-shaped wooden back rib 5 is processed and installed, the lining board 7 is constructed first, followed by the panel 6. Both the lining board and the panel are processed using BIM technology. No bolt holes are left in the lining board. The lining board is laid directly after the dimensions are processed. Before laying the panel, according to the processing drawing, each panel is spaced 8 bolt holes away. When the panel is laid on top of the lining board, all joints are staggered with the lining board.

[0057] Step 4: Use BIM technology to determine the location of electromechanical points, and place the embedded boxes according to the drawings. After the reinforcement of the arch roll structure is tied, use panel 6 and wooden backing to close the formwork on the upper side of the component, and then use tie rods 8 to reinforce the arch roll.

[0058] In this embodiment, after the panel construction is completed, holes are first drilled downwards on the upper side of the panel according to the pre-processed bolt holes. After the structural steel reinforcement and electromechanical pre-embedded construction are completed, the outer side of the component is closed with formwork. Finally, holes are drilled upwards from the edge of the curved wooden back rib to the bolt holes that were previously drilled until they penetrate the formwork on both sides of the component, ensuring the installation of the five-section tie rod.

[0059] Ordinary steel pipes are used to reinforce the arched sidewalls. One end is connected to the sidewall crossbar, and the other end is connected to the pre-embedded φ25 steel bar 16. After all the reinforcement work is completed, C35 fair-faced concrete 21 is poured.

[0060] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
