Description

Technical Field

[0001] This invention belongs to the field of irregular wall construction technology, and specifically relates to a construction method for a petal-shaped hyperbolic composite wall. Background Technology

[0002] With the continuous development and innovation of engineering technology and design concepts, irregular and complex structures have been increasingly widely used in the field of architecture. These structures, with their unique shapes, excellent mechanical properties, and outstanding space utilization, not only meet the modern architectural pursuit of both aesthetics and practicality, but also drive the continuous progress of architectural design and construction technology, leading the future development direction of the construction industry.

[0003] Currently, petal-shaped irregular wall structures are constructed on already completed floors, with the wall surface designed as curved to accommodate the curved decorative layer. However, direct construction of curved walls is difficult, and precision is hard to control, often resulting in regional deformation during construction. This leads to poor overall quality of the petal-shaped wall, failing to meet requirements. Therefore, we propose a construction method for a petal-shaped hyperbolic composite wall structure to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a construction method for a petal-shaped hyperbolic composite wall, which solves the difficulty of directly constructing curved walls.

[0005] This invention is achieved through the following scheme: a construction method for a petal-shaped hyperbolic composite wall, comprising the following steps:

[0006] S1. Using modeling software, create models of the wall structure and wall decoration layer according to the design drawings, and fit the wall structure into multiple wall segments in a polygonal shape.

[0007] S2. Use the 3ds Max slicing tool to cut at all polyline positions of each wall segment to generate multiple plan views. Add annotations to the multiple plan views and output them to form construction drawings. The annotations include construction sequence number, installation angle and installation height.

[0008] S3. Use Rhino software to analyze the inner and outer surface development of each wall segment, and prepare corresponding templates according to each development surface to form multiple one-to-one inner and outer templates.

[0009] S4. According to the construction drawings, set up and fix the outer formwork, steel reinforcement cage and inner formwork corresponding to each wall segment at the designated position on the floor according to the construction sequence, installation angle and installation height. Pour concrete between the outer formwork and the inner formwork so that the concrete wraps the steel reinforcement cage and forms the wall after curing.

[0010] S5. Divide the wall decoration layer according to the broken lines of multiple wall segments to generate multiple wall decoration pieces, and install the multiple wall decoration pieces on the corresponding wall segments.

[0011] A further improvement of the construction method for the petal-shaped hyperbolic composite wall of the present invention is that each wall segment includes multiple construction segments, and the multiple construction segments are connected to the multiple planes in step S2. Figure 1 One-to-one correspondence;

[0012] When performing step S4, multiple construction sections are constructed sequentially from bottom to top.

[0013] A further improvement of the construction method for the petal-shaped hyperbolic composite wall of the present invention is that, before constructing the upper construction segment in each of the two adjacent construction segments, the top of the lower construction segment is roughened.

[0014] A further improvement of the construction method of the petal-shaped hyperbolic composite wall of the present invention is that step S4 further includes the following steps: before pouring concrete, holes are made on the outer formwork corresponding to each construction section, and after pouring concrete, a vibrator is inserted into the hole to vibrate the concrete inside, and after the vibration is finished and the vibrator is removed, the hole is sealed.

[0015] A further improvement of the construction method of the petal-shaped hyperbolic composite wall of the present invention is that, in each of the wall segments, the construction segment at the lower end is an outward-sloping segment and the construction segment at the upper end is an inward-sloping segment.

[0016] Before constructing the outward-sloping section, a support frame is erected on the floor, and the support frame is used to fix the outer formwork corresponding to the outward-sloping section during construction.

[0017] Before constructing the inner section, an outer scaffold is erected on the support frame, and during the construction of the inner section, the outer scaffold is used to fix the outer formwork corresponding to the inner section.

[0018] A further improvement of the construction method of the petal-shaped hyperbolic composite wall of the present invention is that, after constructing the outer template, the outer template and the corresponding inner template are connected and fixed by tie rods when constructing the corresponding inner template.

[0019] A further improvement to the construction method of the petal-shaped hyperbolic composite wall of the present invention is that, after the concrete has cured and formed the wall, the method further includes the following step:

[0020] Remove the inner and outer formwork. First, cut off the part of the tie rod that protrudes from the wall, and then continue to cut off the part of the tie rod that is at least 2mm deep into the wall from the wall surface.

[0021] Apply anti-rust paint to the broken end of the tie rod and fill the area between the broken end of the tie rod and the wall with plaster.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention utilizes BIM technology to optimize the complex ellipsoidal petal-shaped structure, inversely fitting the hyperbolic irregular petal wall into a multi-segment zigzag petal wall. Rhino is used to analyze and match the inner and outer skin surfaces, improving template utilization. 3ds Max slicing tools are used to generate a plan view at the inflection point elevation, facilitating on-site positioning and construction control. By optimizing the wall by replacing curvature with folds, the high cost and high-altitude reinforcement problems associated with using steel formwork are avoided, facilitating formwork erection and construction, and improving accuracy and progress.

[0034] To address the difficulty of directly constructing curved walls, this invention provides a construction method for a petal-shaped hyperbolic composite wall. The following detailed description, in conjunction with accompanying drawings, provides further explanation of this construction method for a petal-shaped hyperbolic composite wall.

[0035] See Figures 1-9 As shown, a construction method for a petal-shaped hyperbolic composite wall includes the following steps:

[0036] S1. Using BIM (Building Information Modeling) software, models of the wall structure and wall decoration layer are created according to the design drawings. The wall structure is fitted into multiple polygonal wall segments 1.

[0037] S2. Using the 3ds Max (3D Studio Max 3D modeling) slicing tool, cut at all polyline positions of each wall segment 1 to generate multiple plan views. After adding annotations to the multiple plan views, output to form construction drawings. The annotations include construction sequence number, installation angle and installation height.

[0038] S3. Use Rhino (Rhinoceros 3D) software to analyze the unfolded surfaces of the inner and outer surfaces of each wall segment 1, and prepare corresponding templates according to each unfolded surface to form multiple one-to-one corresponding inner and outer templates.

[0039] S4. According to the construction drawings, set up and fix the outer formwork, steel reinforcement cage and inner formwork corresponding to each wall segment 1 at the set position on floor 2 according to the construction sequence, installation angle and installation height. Pour concrete between the outer formwork and the inner formwork so that the concrete wraps the steel reinforcement cage. After curing, the wall is formed and the wall has a closing at the top.

[0040] S5. Divide the wall decoration layer according to the broken lines of multiple wall segments 1 to generate multiple wall decoration pieces, and install the multiple wall decoration pieces on the corresponding wall segments 1.

[0041] BIM technology was used to optimize the complex ellipsoidal petal-shaped structure. The hyperbolic irregular petal wall was inversely fitted into a multi-segment zigzag petal wall. Rhino was used to analyze and match the inner and outer skin surfaces to improve the formwork utilization rate. The 3ds Max slicing tool was used to generate a plan view at the inflection point elevation, which facilitates on-site positioning and construction control. By optimizing the wall by replacing curvature with folds, the high cost and high-altitude reinforcement problems caused by using steel formwork were avoided. This facilitated the erection of formwork and improved accuracy and progress. After the wall construction was completed, the wall decoration layer was installed on the wall to ensure that the wall has a petal shape and a consistent appearance.

[0042] Furthermore, in order to better fit the original curved surface, the broken line should be placed in the area where the curve is dense, and the impact of the broken angle on the net height of the stairs should be checked. Fine adjustments should be made while meeting the requirements for net height of stairs and width of platforms.

[0043] Among them, see Figure 3-6 As shown, each wall segment 1 includes multiple construction segments, and these multiple construction segments are connected to multiple planes in step S2. Figure 1 One-to-one correspondence;

[0044] When performing step S4, multiple construction sections are constructed sequentially from bottom to top.

[0045] Segmented construction facilitates the precise setting, adjustment, and fixing of each inner and outer formwork, greatly ensuring the construction accuracy of each segment.

[0046] In this process, before the upper construction section in each of two adjacent construction sections, the top of the lower construction section is roughened.

[0047] By roughening the contact surface area, the connection anchorage between the upper and lower construction sections can be improved.

[0048] Step S4 further includes the following steps: before pouring concrete, make a hole in the outer formwork corresponding to each construction section, with the hole size being 10cm×10cm, and after pouring concrete, use a vibrator to insert into the hole to vibrate the concrete inside, and after the vibration is finished and the vibrator is removed, seal the hole.

[0049] Because the wall is sloping on the facade, it is difficult to insert the vibrator to the bottom of the wall during the concrete pouring process. At the same time, it is difficult for the air bubbles generated during the vibration process to be discharged from the top. Therefore, this application adopts the above design to allow the vibrator to be inserted and the air bubbles generated during the vibration process to be discharged by opening holes in the outer formwork, so as to ensure the forming quality of the wall.

[0050] Among them, see Figure 4-6 As shown, in each wall segment 1, the construction segment at the lower end is the outward-sloping segment 101, and the construction segment at the upper end is the inward-sloping segment 102.

[0051] Before constructing the outward-sloping section 101, a support frame 3 is erected on the floor 2, and the support frame 3 is used to fix the outer formwork corresponding to the outward-sloping section 101 during construction.

[0052] Before constructing the inner section 102, an outer scaffold 4 is erected on the support frame 3, and the outer scaffold 4 is used to fix the outer formwork corresponding to the inner section 102 during the construction of the inner section.

[0053] Furthermore, the height of each erection of the support frame 3 is the height of the fold line position of the fold line wall segment 1. After the support frame 3 is erected, a temporary horizontal template is laid on top to facilitate workers to stand on the horizontal template for point calibration, thereby controlling the tilt angle and corner position of the wall. The support frame 3 can provide stable support for the template. Before each construction section of each wall segment 1 is constructed, a section of support frame 3 is erected to ensure that the height meets the usage requirements. When constructing the inward section 102, an outer frame 4 can be erected on top of the support frame 3 to support the template corresponding to the inward section 102, ensuring its fixation and stability and reducing the probability of deformation.

[0054] Specifically, there is a cavity between the 5.0 elevation cantilever slab and the corresponding construction section, which makes it inconvenient to erect the scaffold 4. In order to facilitate the erection of the scaffold 4, the cavity needs to be temporarily sealed with a cast-in-place reinforced concrete slab, HRB400, 14@200 steel bars are laid, and then a 10cm thick C35 concrete is poured. It can only be chiseled after the scaffold 4 is removed.

[0055] There is a cavity in the middle of the petal wall at the 10.0 elevation, which makes it inconvenient to reinforce the petal wall at the 10.0~13.5 elevation. The cavity needs to be temporarily sealed with cast-in-place reinforced concrete slab, HRB400, 14@200 steel bars are laid, and then 10cm thick C35 concrete is poured. After the formwork is removed, the cavity is chiseled.

[0056] Specifically, both the support frame 3 and the outer frame 4 can be connected and fixed to the outer template by setting multiple diagonal bracing tubes to provide stable support.

[0057] By adopting the above design, the stable support of the formwork for the outward-sloping section 101 and the inward-retracting section 102 can be ensured by using the gradually stacked support frame 3 and the outer frame 4, thereby ensuring construction accuracy.

[0058] In this process, after the outer formwork is constructed, the corresponding inner formwork is constructed by connecting and fixing the outer formwork to the corresponding inner formwork using tie rods 5.

[0059] Furthermore, the inner formwork can be further supported and fixed by using diagonal steel pipes on the inner side of the inner formwork.

[0060] By adopting the above design, the spacing between the inner and outer formwork is ensured by using tie rods 5. The fixed outer formwork can also provide stable support for the inner formwork. In addition, the stability of the inner formwork can be greatly improved by using diagonal bracing steel pipes.

[0061] Among them, see Figure 7 As shown, after the concrete has cured and formed a wall, the following steps are also included:

[0062] Remove the inner and outer formwork. First, cut off the part of the tie rod 5 that protrudes from the wall, and then continue to cut off the part of the tie rod 5 that is at least 2mm deep into the wall from the wall surface.

[0063] Apply anti-rust paint to the break point of tie rod 5, and fill the area between the break point of tie rod 5 and the wall with plaster.

[0064] By adopting the above design, the resulting wall is prevented from being easily corroded and damaged, and the wall surface is ensured to be flat.

[0065] Among them, see Figure 8-9 As shown, before performing step S5, the following steps are also included: a ring of vertical supports 6 are set up on the inner side of the wall and around the wall opening, brackets 8 are fixedly installed on each vertical support 6, steel truss 7 is hoisted to the opening area and fixed on the brackets 8, floor deck 9 template is set up on the steel truss 7, concrete is poured into the mold cavity, and floor deck 9 is formed after curing.

[0066] Specifically, the gaps between the floor deck 9 formwork and the surrounding inward-facing wall section 102 are sealed to prevent grout leakage during the pouring process.

[0067] Furthermore, before constructing the uppermost construction section, the steel truss 7 can be hoisted to the end for installation, and then the construction section can be constructed; this can avoid collisions during the hoisting process or irreversible damage to the wall section.

[0068] By adopting the above design, the stability of the construction of floor deck 9 can be guaranteed.
