Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a construction method for irregular curved surface colonnade projects. Background Technology

[0002] The Irregular Curved Column Colonnade is a sub-project of the Tianbaofeng Packaging Center Technical Renovation Project, located in Tianbaofeng, Erlang Town, Gulin County, Sichuan Province. This irregular curved column colonnade is an irregularly shaped structure with 12 frame columns. The colonnade structure is formed by decorative concrete wall panels and a roof panel. Its design top elevation is 3.55m from the top of the structural slab, and the bottom elevation varies uniformly from -1.5m to -4m. The overall height varies uniformly from 5.1m to 7.5m, with a total building area of ​​approximately 1200m². 2 .

[0003] Chinese invention patent (application number: CN201810531075.0) with publication number CN108412109A discloses a double-centered arrow-shaped cross-arch ceiling structure and its construction method. The double-centered arrow-shaped cross-arch ceiling structure includes a main keel frame, adapters, a back keel frame, and a ceiling panel. The main keel frame is horizontally suspended below the top panel of the structure. The back keel frame is horizontally connected to the bottom of the main keel frame via adapters. The ceiling panel is a GRC ceiling panel, formed by longitudinally splicing a set of cross arches. The transverse ends of each cross arch overlap the tops of the decorative column heads on both sides of the colonnade, and the longitudinal joints of two adjacent cross arches correspond to the decorative column heads. The cross arches are suspended below the corresponding four sets of back keel frames via connecting components set on the GRC reinforcing ribs. This invention solves the technical problems of high installation difficulty, low panel strength, and low construction safety in double-centered arrow-shaped cross-arch ceiling structures.

[0004] Because irregular curved surface colonnade projects have irregular surfaces, high heights, and complex structures, the construction process is difficult and costly. The construction method in the above invention cannot solve the problems of irregular curved surface fair-faced colonnade structures being difficult to form, the style of the curved surface being unreliable, the structural shape being uneven, and the forming quality of the structural entity being low. Summary of the Invention

[0005] In view of this, the present invention proposes a construction method for irregular curved surface colonnade projects, which can solve the problems of difficulty in forming irregular curved surface fair-faced colonnade structures, inability to guarantee the style of curved surface shapes, uneven structural shapes, and low forming quality of structural entities.

[0006] This invention is implemented as follows:

[0007] This invention provides a construction method for irregular curved surface colonnade projects, comprising the following steps:

[0008] S010: Create a 3D model of the irregular curved column corridor and generate the construction plan, horizontal and vertical cross-sections;

[0009] S020: Based on the construction plan, the irregular curved column corridor is divided into three construction sections;

[0010] S030: Based on the horizontal and vertical cross-sectional views, form an assembly scheme for each construction section, and number and position the templates according to the assembly scheme;

[0011] S040: Based on the horizontal and vertical cross-sectional views, lay out and locate the construction sections on site for each section;

[0012] S050: Based on the aforementioned layout and positioning, erect steel pipe scaffolding on-site for each of the aforementioned construction sections;

[0013] S060: A shape frame is set on the steel pipe frame, and the template is spliced ​​on the shape frame to form a template shape;

[0014] S070: Process the surface of the template shape;

[0015] S080: Tie steel bars inside the template shape and reinforce the shape frame;

[0016] S090: Pour fair-faced concrete in layers into the template shape to form the irregular curved column corridor;

[0017] S100: Remove the template and perform surface treatment on the irregular curved column.

[0018] The technical effects of the construction method for irregular curved surface colonnade projects provided by this invention are as follows: By utilizing the deformation of the wooden formwork itself, irregular curved surface structures can be implemented, effectively ensuring the shape and improving the forming quality of the structural entity. This solves the problems of the inability to implement architectural nodes and the lack of smoothness in the structural shape of irregular curved surface structures. By using steel reinforcement binding, the rigidity and strength requirements of fair-faced concrete can be met. By treating the formwork surface with high-strength mortar and water-resistant putty, the irregular curved surface shape can be precisely implemented. By applying epoxy resin release agent to the water-resistant putty surface, the problem of adhesion between the concrete surface and the formwork can be solved, ensuring the smoothness of the fair-faced concrete surface, forming its own texture, and improving the construction effect of fair-faced concrete. Through this construction method for irregular curved surface colonnade projects, the construction quality and efficiency can be effectively improved.

[0019] Based on the above technical solution, the construction method for irregular curved surface colonnade engineering of the present invention can be further improved as follows:

[0020] Specifically, S090 includes the following steps:

[0021] (1) Clean the inside of the template shape and moisten it with water;

[0022] (2) Pour a 5cm thick cement mortar with the same composition as the fair-faced concrete at the base of the template shape, and pour it into the template evenly with a shovel.

[0023] (3) Pour the cement mortar in layers and use a ruler to control the layer thickness of the cement mortar to 40cm. At the same time, use a vibrator to vibrate the cement mortar from top to bottom to make the cement mortar vibrate evenly.

[0024] (4) When pouring to the top of the layer, a vibrating screen device is installed at the outlet of the stone feeding pipe. Washed stones are added to the cement mortar through the stone feeding pipe to ensure that the falling direction of the stones is consistent when they are poured.

[0025] (5) The upper layer of fair-faced concrete is poured before the lower layer of fair-faced concrete has initially set.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting up a vibrating screen device, the falling direction of the stones can be kept consistent, the stones in the poured concrete can be evenly distributed, and the strength of the concrete at the root and top can be guaranteed; the function of vibration is to allow the air bubbles in the concrete to float up and dissipate fully.

[0027] Specifically, S060 includes the following steps:

[0028] (1) Based on the horizontal and vertical cross-sectional views, a vertical structural frame is set on the steel pipe frame;

[0029] (2) Based on the template number, and following the construction sequence of vertical first and then horizontal, the template is spliced ​​on the vertical structural frame to form a vertical structural template shape;

[0030] (3) Based on the three-dimensional model, a transition structure support frame is erected on the top of the steel pipe frame;

[0031] (4) Based on the horizontal and vertical cross-sectional views, a transition structure frame is set on the transition structure support frame;

[0032] (5) Based on the template number, and following the construction sequence of first vertical and then horizontal, the template is spliced ​​on the transition structure frame to form the transition structure template shape;

[0033] (6) Based on the three-dimensional model, a horizontal structural support frame is erected on top of the transition structural support frame, and a horizontal top plate is laid on the horizontal structural support frame;

[0034] (7) Combining the horizontal and vertical cross-sectional views, stack the shaped wooden keel in layers on the horizontal top plate to form a horizontal structural shaped skeleton;

[0035] (8) Combine the template number with the template and splice the template on the horizontal structural frame to form a horizontal structural template shape.

[0036] Furthermore, the step of setting up a vertical structural framework on the steel pipe frame specifically involves:

[0037] Based on the outline lines in the vertical cross-sectional view, a vertical keel is installed every 50cm on the steel pipe frame; based on the contour lines in the horizontal cross-sectional view, a horizontal keel is installed every 50cm on the steel pipe frame; the vertical keels and the horizontal keels together constitute the vertical structural framework.

[0038] Furthermore, the step of setting the transition structure frame on the transition structure support frame specifically involves:

[0039] Based on the outline lines in the vertical cross-sectional view, a vertical steel reinforcement skeleton is set every 30cm on the steel pipe frame; based on the contour lines in the horizontal cross-sectional view, a horizontal steel reinforcement skeleton is set every 30cm on the steel pipe frame; the vertical steel reinforcement skeleton and the horizontal steel reinforcement skeleton together constitute the transition structure styling skeleton.

[0040] Furthermore, the styling framework includes a vertical structural styling framework, a transitional structural styling framework, and a horizontal structural styling framework; the template styling includes a vertical structural template styling framework, a transitional structural template styling framework, and a horizontal structural template styling framework.

[0041] Specifically, step S040 is as follows:

[0042] Based on the horizontal and vertical cross-sectional views, the ground of the construction site is cleaned and leveled with mortar; the vertical accuracy of construction, the projection of the plane axis and the elevation of the elevation are checked; after the axis is projected, the geometric dimensions of the vertical components and the template positioning lines are laid out, and the control lines are checked; the edge lines of the wall and the template position lines and the wall axis are marked on the floor.

[0043] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: through the above steps, the installation error of the template can be eliminated within the adjacent axis interval, preventing the generation of cumulative error.

[0044] Specifically, step S070 is as follows:

[0045] First, high-strength mortar is used to rough shape the surface of the template, and fiberglass mesh is added at the junction of the template to ensure the adhesion of the mortar. Then, after the high-strength mortar is formed, high-strength water-resistant putty is applied to the surface of the high-strength mortar. Finally, epoxy resin is applied to the surface of the template for fine shaping and surface isolation.

[0046] The specific steps of tying reinforcing bars within the template shape are as follows:

[0047] Based on the three-dimensional model, the steel bars are processed on-site at the construction site; debris on the assembled template is cleared, and the vertical bars are tied first, followed by the horizontal bars; based on the horizontal and vertical cross-sectional views, the steel bars are bent, and the outer irregular stirrups are tied layer by layer from bottom to top.

[0048] Specifically, step S100 is as follows:

[0049] First, the fair-faced concrete is covered and watered for curing. Then, the surface of the cured fair-faced concrete is cleaned to remove dust and adhering particles. Finally, a protective layer of fair-faced concrete is applied to the surface of the fair-faced concrete.

[0050] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting up a clear water protective layer, it can have good stain resistance and excellent outdoor gloss and color retention. It can penetrate into the interior of the clear water concrete, and allow the evaporation of water vapor in the clear water concrete while preventing the capillary pores of the clear water concrete from absorbing water, thus providing good protection for the clear water concrete.

[0051] Compared with existing technologies, the beneficial effects of the construction method for irregular curved surface colonnades provided by this invention are as follows: By utilizing the deformation of the wooden formwork itself, irregular curved surface structures can be implemented, effectively ensuring the shape and improving the forming quality of the structural entity. This solves the problems of the inability to implement architectural nodes and the lack of smoothness in the structural shape of irregular curved surface structures. By using steel reinforcement binding, the rigidity and strength requirements of fair-faced concrete can be met, improving the forming quality of the structural entity. By treating the formwork surface with high-strength mortar and water-resistant putty, the curved surface shape can be precisely implemented, resulting in a smooth structural shape. By applying epoxy resin release agent to the water-resistant putty surface, the problem of adhesion between the concrete surface and the formwork can be solved, ensuring the smoothness of the fair-faced concrete surface, forming its own texture, and improving the construction effect of fair-faced concrete. Through this construction method for irregular curved surface colonnades, the construction quality and efficiency can be effectively improved. Attached Figure Description

[0063] like Figure 1 The diagram shows a flowchart of a construction method for an irregular curved surface colonnade provided by this invention. Specifically, this invention includes the following steps:

[0064] S010: Create a 3D model of the irregular curved column corridor and generate the construction plan, horizontal and vertical cross-sections;

[0065] S020: Based on the construction plan, the irregular curved column colonnade is divided into three construction sections;

[0066] S030: Combining horizontal and vertical cross-sectional views, formulate an assembly plan for each construction section, and number and position the formwork according to the assembly plan;

[0067] S040: Based on the horizontal and vertical cross-sectional views, lay out and position the lines on site for each construction section;

[0068] S050: Based on the layout and positioning, erect steel pipe scaffolding on site for each construction section;

[0069] S060: Set up a shape frame on a steel pipe frame, and splice templates on the shape frame to form a template shape;

[0070] S070: Surface treatment of the template shape;

[0071] S080: Tie steel bars inside the template shape and reinforce the shape frame;

[0072] S090: Pour fair-faced concrete into the template shape in layers to form an irregular curved column colonnade;

[0073] S100: Remove the formwork and perform surface treatment on the irregular curved column colonnade.

[0074] It should be noted that the irregular curved colonnade consists of 12 decorative columns, with the overall height of the columns ranging from 5.1m to 7.8m. When dividing the colonnade into sections, based on the structural stress requirements, horizontal sections are preferentially selected at exposed joints, followed by cleft joints, while avoiding special exposed concrete component areas such as inside and outside corners. The elevation of individual columns is determined by dividing the horizontal sections at the concave junction of the colonnade dome. Vertical sections are selected near the bottom of the beams and near the structural surfaces of the floors.

[0075] The project divides the colonnades from #1 to #4 into one section, the colonnades from #5 to #8 into two sections, and the colonnades from #9 to #12 into three sections. The construction sequence is: first the first section, then the second section, and finally the third section.

[0076] The specific pouring method for fair-faced concrete is as follows:

[0077] The shaped columns #1 to #5 were poured in three stages: the first stage was poured up to the top of the 1m tie beam; the second stage was poured from the top of the 1m tie beam up to the dome shell; and the third stage was poured to form the structural beams and slabs.

[0078] The decorative columns #7, #10, and #12 were poured in four stages: the first stage was poured up to the top of the -1m tie beam; the second stage was poured up to the top of the -1m to 1m tie beam, including the vertical decorative slab and tie beam; the third stage was poured from the top of the 1m tie beam up to the dome shell; and the fourth stage was poured up to the structural beam and slab sections.

[0079] The decorative columns #6, #8, #9, and #11 were poured in three stages: the first stage was poured to the area above the 1m tie beam to provide a working surface; the second stage was poured from the top of the tie beam to the dome shell; and the third stage was poured to the structural beam and slab area.

[0080] Among them, the bottom of the decorative columns within 1m above the foundation is all poured with concrete, and the construction joint is left on the upper part of the horizontal tie beam. The construction joint is treated by roughening and filling with cement grout interface agent.

[0081] Specifically, in the above technical solution, S090 includes the following steps:

[0082] (1) Clean the inside of the template and moisten it with water;

[0083] (2) Pour a 5cm thick cement mortar with the same composition as fair-faced concrete at the base of the template shape, and pour it into the mold evenly with a shovel.

[0084] (3) Pour the cement mortar in layers and use a ruler to control the layer thickness of the cement mortar to 40cm. At the same time, use a vibrator to vibrate from top to bottom to make the cement mortar vibrate evenly.

[0085] (4) When pouring to the top of the layer, install a vibrating screen device at the outlet of the stone feeding pipe, and add washed stones to the cement mortar through the stone feeding pipe to ensure that the falling direction of the stones is consistent when they are poured.

[0086] (5) The upper layer of fair-faced concrete is poured before the lower layer of fair-faced concrete has initially set.

[0087] like Figure 2-3 As shown, the vibrating screen device used in step S090 includes two housings 10 symmetrically arranged on the side wall at the outlet of the stone feeding pipe 20. Electromagnetic coils 11 are respectively arranged inside the two housings 10. The winding directions of the coils on the two electromagnetic coils 11 are opposite. Magnets 12 are respectively arranged on the side of the two electromagnetic coils 11 near the stone feeding pipe 20. The magnets 12 are slidably connected to the bottom wall of the housing 10 through a sliding connection mechanism.

[0088] A support rod 121 is provided at the bottom of the magnet 12, and a slider 122 is fixedly connected to the bottom of the support rod 121. A slide rail 101 is provided on the bottom wall of the housing 10. The slide rail 101 is a dovetail groove. The slider 122 is adapted to the cross-sectional shape of the slide rail 101. The sliding connection mechanism includes the slider 122 and the slide rail 101.

[0089] In use, after energizing the electromagnetic coils 11, the two electromagnetic coils 11 generate electromagnetic fields in opposite directions. One electromagnetic coil 11 attracts the nearby magnet 12, while the other electromagnetic coil 11 repels the nearby magnet 12. When the electromagnetic coil 11 repels the magnet 12, the magnet 12 moves away from the electromagnetic coil 11 under the action of the sliding connection mechanism, eventually hitting the inner wall of the housing 10. When the electromagnetic coil 11 attracts the magnet 12, the magnet 12 moves closer to the electromagnetic coil 11 under the action of the sliding connection mechanism. By changing the direction of the current flowing into the electromagnetic coils 11, the magnets 12 placed near the two electromagnetic coils 11 can be made to alternately strike the inner wall of the housing 10 at the same frequency, thereby alternately releasing stone feed from both sides of the stone feeding pipe 20. The impact force of the magnet 12 on the wall of the stone feeding pipe 20 can be adjusted by changing the current flowing through the electromagnetic coil 11, thus achieving a vibration effect. Because denser objects are located at the bottom of the vibrating screen area, when the stones pass through the discharge port, they are flipped by the vibrating screen, with the sidewalls with larger surface areas facing down. After falling out of the discharge port, the sidewalls with larger surface areas first contact the cement mortar and sink under gravity. During the sinking process, the stone experiences the greatest resistance due to the largest contact area with the cement mortar, resulting in the slowest sinking speed. This prevents the stones from settling too quickly and accumulating in the lower part of the cement mortar, thus avoiding uneven distribution of stones in the cement mortar.

[0090] In the irregular curved surface colonnade project, fair-faced concrete produced by a separate production line is preferred to ensure that the raw materials and mix proportions remain unchanged; a twin-shaft forced mixer is used with a mixing time of 120 seconds to control the good workability of the concrete and maintain a 60-day drying shrinkage rate of no more than 0.022%.

[0091] Fair-faced concrete is composed of cement, coarse aggregate, fine aggregate, fly ash, mineral powder, and admixtures. The maximum water-cement ratio of fair-faced concrete is 0.36; the total amount of gelling material is ≥380kg / m³. 3 And ≤450kg / m 3 The fly ash content is 25-30%; the alkali content is ≤3 kg / m³. 3 Maximum chloride ion content: 0.08%;

[0092] The cement used is silicate cement or ordinary silicate cement with a strength of not less than 42.5.

[0093] The coarse aggregate selected is granular crushed stone with a mud content of less than 1%, a mud lump content of less than 0.5%, a needle-like and flaky particle content of no more than 15%, uniform color, clean, low porosity, equigranular stone shape, weather resistance, hardness, and high strength.

[0094] The fine aggregate selected is medium-coarse river sand with a fineness modulus greater than 2.6, a mud content of no more than 1.5%, a mud lump content of no more than 1.0%, low porosity, uniformity, hardness, cleanliness, and strong weather resistance.

[0095] The fly ash selected is Grade I fly ash with a fineness of no more than 12%, a water requirement ratio of no more than 100%, and a loss on ignition of no more than 5%; the mineral powder selected is mineral powder with a 7-day activity index of ≥65%.

[0096] The admixture can be a polycarboxylate-based high-efficiency liquid water-reducing agent, with a concrete water reduction rate of ≥15%.

[0097] In the above technical solution, S060 specifically includes the following steps:

[0098] (1) Combining the horizontal and vertical cross-sectional views, a vertical structural framework is set on the steel pipe frame;

[0099] (2) Based on the template numbering, and following the construction sequence of vertical first and horizontal later, the templates are spliced ​​on the vertical structural frame to form the vertical structural template shape;

[0100] (3) Combine the three-dimensional model and erect a transition structure support frame on the top of the steel pipe frame;

[0101] (4) Combining the horizontal and vertical cross-sectional views, set up the transition structure frame on the transition structure support frame;

[0102] (5) Combine the template numbering and follow the construction sequence of vertical first and horizontal later, splice the templates on the transition structure frame to form the transition structure template shape;

[0103] (6) Based on the three-dimensional model, a horizontal structural support frame is erected on top of the transition structural support frame, and a horizontal top plate is laid on the horizontal structural support frame;

[0104] (7) Combining the horizontal and vertical cross-sectional views, stack the shaped wooden keel in layers on the horizontal top plate to form a horizontal structural styling skeleton;

[0105] (8) Combine the template numbers and splice the templates on the horizontal structural frame to form a horizontal structural template shape.

[0106] It should be noted that the template uses a double-layer high-quality template system. The bottom lining is a 12 mm thick plywood template, and the front panel is a 4 mm thick high-quality clear water special film-coated board. The installation joint size is controlled within 0.5 mm.

[0107] In this process, the formwork at the inside and outside corners overlaps in a continuous joint, forming a smooth, rounded surface. To prevent grout leakage and contamination of the constructed wall surface during the pouring of the upper and lower layers of fair-faced concrete, sponge strips are attached to the formwork joints for sealing. The adhesive side of the sponge strip is attached to the formwork to prevent the adhesive from contaminating the formed fair-faced concrete. In addition, when attaching the sponge strip, a gap of about 3mm is left between the sponge strip and the fair-faced concrete surface to avoid contamination when the two formwork pieces are pressed together. When the formwork is joined, to prevent grout leakage during mortar pouring, high-quality foam adhesive strips are applied or attached to the horizontal joints, and tape is added to the back of the horizontal joints.

[0108] Furthermore, in the above technical solution, the specific steps for setting up a vertical structural framework on the steel pipe frame are as follows:

[0109] Based on the outline lines in the vertical section view, a vertical keel is set every 50cm on the steel pipe frame; based on the contour lines in the horizontal section view, a horizontal keel is set every 50cm on the steel pipe frame; the vertical and horizontal keels together form the vertical structural framework.

[0110] It should be noted that the vertical and horizontal joists are made of 50mm×100mm square timber.

[0111] Furthermore, in the above technical solution, the specific step of setting the transition structure framework on the transition structure support frame is as follows:

[0112] Based on the outline lines in the vertical section view, a vertical steel reinforcement skeleton is set every 30cm on the steel pipe frame; based on the contour lines in the horizontal section view, a horizontal steel reinforcement skeleton is set every 30cm on the steel pipe frame; the vertical and horizontal steel reinforcement skeletons together constitute the transition structure framework.

[0113] It should be noted that the vertical and horizontal steel reinforcement cages are made of 22mm diameter prefabricated steel bars.

[0114] Furthermore, in the above technical solution, the styling framework includes a vertical structural styling framework, a transitional structural styling framework, and a horizontal structural styling framework; the template styling includes a vertical structural template styling framework, a transitional structural template styling framework, and a horizontal structural template styling framework.

[0115] In the above technical solution, step S040 specifically includes:

[0116] Based on the horizontal and vertical cross-sectional views, the ground of the construction site is cleaned and leveled with mortar; the vertical accuracy of the construction, the projection of the plane axis and the elevation of the elevation are checked; after the axis is projected, the geometric dimensions of the vertical components and the template positioning lines are laid out, and the control lines are checked; the wall edge lines, template position lines and wall axis lines are marked on the floor.

[0117] In the above technical solution, the steps in S070 are as follows:

[0118] First, use high-strength mortar to rough shape the surface of the template, and add fiberglass mesh at the junction of the template to ensure the adhesion of the mortar; then, after the high-strength mortar has formed, apply high-strength water-resistant putty to the surface of the high-strength mortar; finally, apply epoxy resin to the surface of the template for fine shaping and surface isolation.

[0119] In the above technical solution, the specific steps for tying reinforcing bars within the formwork are as follows:

[0120] Using the 3D model, steel bars are processed on-site at the construction site; debris on the assembled formwork is cleared, vertical bars are tied first, and then horizontal bars are tied; using the horizontal and vertical cross-sectional views, the steel bars are bent, and the outer irregular stirrups are tied layer by layer from bottom to top.

[0121] In the above technical solution, step S100 specifically includes:

[0122] First, cover and water the fair-faced concrete for curing. Then, clean the surface of the cured fair-faced concrete to remove dust and adhering particles. Finally, apply a fair-faced protective layer to the surface of the fair-faced concrete.

[0123] It should be noted that the clear water protective layer includes a primer layer, a mid-coat layer, and a topcoat layer.

[0124] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
