Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of curved inclined concrete wall construction, specifically relating to a construction structure and construction verification method for curved inclined concrete structural walls. Background Technology
[0002] Currently, with the development of the times, building designs are becoming more personalized. For example, the sides of buildings can be designed as various curved structures.
[0003] In existing technologies, concrete can be poured into steel or wooden molds for curved, sloping concrete structural walls, thus transforming two-dimensional drawings into a three-dimensional curved, sloping concrete structural wall. The design of curved, sloping concrete structural walls is generally unique; they are not typically designed in the same style as those in other buildings. Therefore, when constructing a curved, sloping concrete structural wall using steel molds, the steel molds become unusable, as one mold can only build one curved, sloping concrete structural wall of a fixed size. However, due to the high construction cost of steel molds and their low reuse rate, using steel molds for pouring concrete is not the optimal choice.
[0004] When constructing an arc-shaped inclined concrete structural wall using wooden formwork, an external scaffold (e.g., a grid-shaped external support) is used to support the wooden formwork. Because the degree of inclination of the arc-shaped inclined concrete structural wall varies, the required length of the scaffold crossbars also varies. For example, when the arc-shaped inclined concrete structural wall has a bowl-shaped structure, the length of the scaffold crossbars gradually decreases from bottom to top. Once the scaffold is erected, the wooden formwork is placed on the side of the scaffold closest to the arc-shaped inclined concrete structural wall, and then concrete is poured into the wooden formwork to complete the construction of the arc-shaped inclined concrete structural wall.
[0005] However, using wooden formwork to construct curved, inclined concrete structural walls presents the following technical problems: First, before constructing the curved, inclined concrete structural wall, the lengths of multiple scaffold crossbars need to be calculated manually, and there are bound to be some installation errors during the manual installation of the crossbars. Second, the scaffolding construction process consumes a significant amount of manpower and time; if a significant deviation from the design drawings is found after the scaffolding is completed, rework and modification are very difficult. Third, once the scaffolding is completed and concrete is poured onto the wooden formwork to obtain the curved, inclined concrete structural wall, it is impossible to measure the curved, inclined concrete structural wall, meaning it is impossible to determine whether the construction of the curved, inclined concrete structural wall is accurate. Summary of the Invention
[0006] To solve the above-mentioned technical problems, the present invention provides a construction structure and construction verification method for an arc-shaped inclined concrete structural wall. The arc of the wooden formwork of the wall can be measured twice before the wall is poured, which greatly improves the construction accuracy of the wall. At the same time, the arc of the wall itself can be measured after the wall is poured to verify whether the wall construction is accurate.
[0007] The technical solution adopted in this invention is: a construction structure for an arc-shaped inclined concrete structural wall, characterized in that: it includes a bottom plate and a top plate for limiting the arc-shaped inclined concrete structural wall; multiple columns are constructed between the bottom plate and the top plate; the arc-shaped inclined concrete structural wall is shaped by an auxiliary forming component before pouring; the auxiliary forming component includes an inner wooden mold and an outer wooden mold; the inner wooden mold and the outer wooden mold are remeasured by an arc-shaped measuring tool; a wall reinforcement cage is set between the inner wooden mold and the outer wooden mold; the inner wooden mold and the outer wooden mold are connected by multiple bolts; multiple reinforcing joists are vertically arranged around the outer perimeter of the inner wooden mold and the outer wooden mold; the outer perimeter of the multiple reinforcing joists is reinforced by an external support frame; the arc-shaped inclined concrete structural wall is not closed, and the inner wooden mold and the outer wooden mold are not closed;
[0008] Both the bottom plate and the top plate have circular cross-sections, but the dimensions of the circles are different.

[0010] The above-mentioned construction structure for an arc-shaped inclined concrete structural wall is characterized in that: gaps are provided between the wall reinforcement cage and the inner and outer wooden formwork.
[0011] The above-mentioned construction structure for an arc-shaped inclined concrete structural wall is characterized in that: the top of the wooden formwork outside the wall includes a pouring port.
[0012] The above-mentioned construction structure for an arc-shaped inclined concrete structural wall is characterized in that: the top slab is shaped by a wooden mold, and the edges of the wooden mold are provided with tongue-and-groove wooden molds.
[0013] The above-mentioned construction structure for an arc-shaped inclined concrete structural wall is characterized in that: the arc-shaped measuring tool includes a horizontal bar and a ruler; multiple openings are spaced apart on the horizontal bar, and the ruler is set in the openings.
[0014] The above-mentioned construction structure of an arc-shaped inclined concrete structural wall is characterized in that: when the size of the bottom plate is larger than the size of the top plate, the longitudinal section of the building formed by the bottom plate, the arc-shaped inclined concrete structural wall, and the top plate is an isosceles trapezoid with a larger base and a smaller top.
[0015] When the size of the base plate is smaller than the size of the top plate, the longitudinal section of the building formed by the base plate, the arc-shaped inclined concrete structural wall, and the top plate is an isosceles trapezoid with a smaller base and a larger top.
[0016] Meanwhile, this invention also discloses a simple, rationally designed, and highly accurate construction re-measurement method for curved inclined concrete structural walls, characterized by the following steps:
[0017] Step S1: Construction of the base slab;
[0018] Step S2: Casting of the column, followed by casting of the top plate on the top of the column;
[0019] Step S3: Sequentially install the external support frame of the external wooden formwork, the reinforcing keel of the external wooden formwork, and the external wooden formwork itself;
[0020] Step S4: Use the arc-shaped measuring tool to remeasure the wooden mold outside the wall;
[0021] Step S5: If the chord height of the external wooden formwork is consistent with the theoretical chord height of the curved inclined concrete structural wall, then the wall reinforcement cage and the internal wooden formwork are set in sequence; if they are inconsistent, then after adjusting the setting position of the external wooden formwork, step S4 is executed until the chord height of the external wooden formwork is consistent with the theoretical chord height.
[0022] Step S6: Use the arc-shaped measuring tool to re-measure the wooden mold inside the wall;
[0023] Step S7: If the chord height of the wooden mold inside the wall is consistent with the theoretical chord height, then install the screw and the reinforcing keel of the wooden mold inside the wall in sequence; if they are inconsistent, then adjust the setting position of the wooden mold inside the wall and execute step S6 until the chord height of the wooden mold inside the wall is consistent with the theoretical chord height.
[0024] Step S8: Construction of the arc-shaped inclined concrete structural wall;
[0025] Step S9: Remove the inner wooden formwork, the outer wooden formwork, and the external support frame;
[0026] Step S10: Re-measure the curved inclined concrete structural wall to determine whether the chord height of the curved inclined concrete structural wall is consistent with the theoretical chord height.
[0027] The beneficial effects are inferred as follows:
[0028] The existing technology for constructing curved, inclined concrete structural walls using wooden formwork presents the following technical problems: First, there are always some human error in the installation of the scaffolding. Second, the scaffolding construction process consumes a significant amount of manpower and time; if a significant deviation from the design drawings is found after the scaffolding is completed, rework and modification are very difficult. Third, it is impossible to measure the curved, inclined concrete structural wall, meaning it is impossible to determine whether the construction of the curved, inclined concrete structural wall is accurate.
[0029] In the present invention, firstly, the position of the curved inclined concrete wall can be defined based on the position of the bottom plate and the top plate. Furthermore, the accurate construction of the curved inclined concrete wall can be ensured based on the wooden formwork inside and outside the wall, avoiding the large human installation errors and rework due to large deviations in the curvature of the wall after construction, which are common in the prior art. Secondly, curved measuring tools can be used to measure the wall formwork and the wall itself, ensuring the accuracy of the wall construction and verifying the accuracy of the wall curvature after construction, avoiding the situation in the prior art where it is impossible to determine whether the construction is accurate.
[0030] In summary, by adopting the technical solution of the present invention, the curvature of the wooden formwork of the wall can be measured twice before the wall is poured, and the curvature of the wall itself can be measured after the wall is poured, which greatly improves the construction accuracy of the curved inclined concrete wall.

[0047] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0048] It should be noted that, unless otherwise specified, the embodiments and features of the embodiments in this invention can be combined with each other. The invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0049] The existing technology for constructing curved, inclined concrete structural walls using wooden formwork presents the following technical problems: First, before constructing the curved, inclined concrete structural wall, the lengths of multiple scaffold crossbars need to be calculated manually, and there are bound to be some installation errors during the manual installation of the crossbars. Second, the scaffolding construction process consumes a significant amount of manpower and time; if a significant deviation from the design drawings is found after the scaffolding is completed, rework and modification are very difficult. Third, once the scaffolding is completed and concrete is poured onto the wooden formwork to obtain the curved, inclined concrete structural wall, it is impossible to measure the curved, inclined concrete structural wall, meaning it is impossible to determine whether the construction of the curved, inclined concrete structural wall is accurate.
[0050] Based on this, embodiments of the present invention provide a construction structure and construction re-measurement method for an arc-shaped inclined concrete structural wall. The arc of the wooden formwork of the wall can be measured twice before the wall is poured, which greatly improves the construction accuracy of the wall. At the same time, the arc of the wall itself can be measured after the wall is poured to verify whether the wall construction is accurate.
[0051] Figure 1 This is a schematic diagram of a construction structure for an arc-shaped inclined concrete structural wall provided by the present invention. Figure 2 This is a cross-sectional view of the construction structure of the arc-shaped inclined concrete structural wall provided by the present invention, combined with... Figure 1 and Figure 2 The aforementioned construction structure includes: a base plate 1 and a top plate 2 for limiting the curved inclined concrete structural wall; multiple columns 3 are constructed between the base plate 1 and the top plate 2; the curved inclined concrete structural wall is shaped by an auxiliary forming component 4 before pouring; the auxiliary forming component 4 includes an inner wooden mold 5 and an outer wooden mold 6; the inner wooden mold 5 and the outer wooden mold 6 are remeasured by an arc-shaped measuring tool 7; a wall reinforcement cage 11 is set between the inner wooden mold 5 and the outer wooden mold 6; the inner wooden mold 5 and the outer wooden mold 6 are connected by multiple bolts 8; multiple reinforcing joists 9 are vertically set around the outer perimeter of the inner wooden mold 5 and the outer wooden mold 6; the outer perimeter of the multiple reinforcing joists 9 is reinforced by an external support frame 10; the curved inclined concrete structural wall is not closed, and the inner wooden mold 5 and the outer wooden mold 6 are not closed.
[0052] Both the bottom plate 1 and the top plate 2 have circular cross-sections, but the dimensions of the circles are different.
[0053] First, the relevant structural terms and concepts in the construction process of the curved inclined concrete structural wall are explained.
[0054] Among them, the base plate 1 can bear the weight of the curved inclined concrete structural wall in a static state and play a supporting role for the curved inclined concrete structural wall.
[0055] Top plate 2 can protect against rain and snow in nature and provide a covering and protection for the curved and inclined concrete structural wall.
[0056] The column 3 can support the top plate 2, dispersing the pressure of the top plate 2 on the curved inclined concrete structural wall, thereby ensuring the stability of the curved inclined concrete structural wall.
[0057] When the construction positions of the base plate 1 and the top plate 2 are accurate, the construction position of the curved inclined concrete structural wall is also accurate.
[0058] The auxiliary forming component 4 can be used to construct the wall formwork for the curved and inclined concrete structural wall. Specifically, the outline of the curved and inclined concrete structural wall can be constructed using the inner wooden formwork 5 and the outer wooden formwork 6.
[0059] It is understandable that if the curvature of the wooden formwork 5 inside the wall and the wooden formwork 6 outside the wall is accurate, then the curvature of the curved inclined concrete structural wall will be accurate after the curved inclined concrete structural wall is poured.
[0060] The arc measuring tool 7 can measure the arc of the erected wooden mold 5 inside the wall and the wooden mold 6 outside the wall before the arc-shaped inclined concrete structural wall is poured. When the arc of the above-mentioned wooden mold is consistent with the theoretical arc of the arc-shaped inclined concrete structural wall, the accurate construction (i.e., pouring) of the arc-shaped inclined concrete structural wall is completed.
[0061] Furthermore, the arc measuring tool 7 can check the curvature of the constructed arc-shaped inclined concrete structural wall after it has been poured. If the actual curvature of the arc-shaped inclined concrete structural wall matches the theoretical curvature, the construction of the arc-shaped inclined concrete structural wall is accurate.
[0062] The screw 8 can reinforce the wooden mold 5 inside the wall and the wooden mold 6 outside the wall to ensure the stability of the wall during the pouring process.
[0063] The reinforcing keel 9 and the external support frame 10 can support the wooden formwork of the wall (i.e., the wooden formwork inside the wall 5 and the wooden formwork outside the wall 6), ensuring the stability of the wall during the pouring process.
[0064] It is understood that the present invention aims to construct an arc-shaped inclined wall. When the cross-sections of both the base plate 1 and the top plate 2 are circular (e.g., partial arcs rather than complete arcs), the wall is arc-shaped, meaning it has a certain degree of curvature, and the curvature of each surface of the wall is the same. When the cross-sections of both the base plate 1 and the top plate 2 are circular (e.g., partial arcs rather than complete arcs), and when the two circles have the same center but different radii, the wall is inclined.
[0065] It should be noted that if the two circles have different centers, the wall will also be tilted, but the circles will be ellipses, and the corresponding wall curvature will be inconsistent, that is, the degree of bending of the wall will be inconsistent. Specifically, the theoretical curvature of the wall can be set to ensure that the actual curvature of the wall is consistent with the theoretical curvature.
[0066] The beneficial effects are inferred as follows:
[0067] The existing technology for constructing curved, inclined concrete structural walls using wooden formwork presents the following technical problems: First, there are always some human error in the installation of the scaffolding. Second, the scaffolding construction process consumes a significant amount of manpower and time; if a significant deviation from the design drawings is found after the scaffolding is completed, rework and modification are very difficult. Third, it is impossible to measure the curved, inclined concrete structural wall, meaning it is impossible to determine whether the construction of the curved, inclined concrete structural wall is accurate.
[0068] In the present invention, firstly, the position of the curved inclined concrete wall can be defined based on the position of the bottom plate and the top plate. Furthermore, the accurate construction of the curved inclined concrete wall can be ensured based on the wooden formwork inside and outside the wall, avoiding the large human installation errors and rework due to large deviations in the curvature of the wall after construction, which are common in the prior art. Secondly, curved measuring tools can be used to measure the wall formwork and the wall itself, ensuring the accuracy of the wall construction and verifying the accuracy of the wall curvature after construction, avoiding the situation in the prior art where it is impossible to determine whether the construction is accurate.
[0069] In summary, by adopting the technical solution of the present invention, the curvature of the wooden formwork of the wall can be measured twice before the wall is poured, and the curvature of the wall itself can be measured after the wall is poured, which greatly improves the construction accuracy of the curved inclined concrete wall.
[0070] First, before constructing the curved, sloping concrete structural wall, BIM software can be used to design a model of the curved, sloping concrete structural wall that meets the design requirements (e.g., chord length 500mm, chord height 2mm). For example, Figure 3 A schematic diagram of a model of an arc-shaped inclined concrete structural wall provided in an embodiment of the present invention.
[0071] Understandably, after the wall model is designed, it is necessary to design the size of the small wooden blocks in the corresponding wooden wall mold, and then assemble the wooden wall mold by piecing together the small wooden blocks. Figure 4 This is a planar unfolded schematic diagram of the wooden wall formwork provided in an embodiment of the present invention. Wherein, straight line AB is the chord length, CD is the chord height, arc EF is the arc length of the lower opening of the wall, and AB is the arc length of the upper opening of the wall.
[0072] Secondly, once the wall model is designed, the bottom and top arc lengths of the wall can be determined. This allows CAD software to be used to design the dimensional parameters of the small wooden blocks (e.g., the length and width of the small wooden blocks, and the consistent thickness of the blocks). For example, Figure 5 This is a schematic diagram showing the dimensions of the small wooden blocks in the wall formwork provided by the present invention. The length of each small wooden block is 'a', and its width is 'b'.
[0073] It should be noted that the size of the small wooden blocks used to assemble the inner wooden mold 5 of the wall is the first size, and the size of the small wooden blocks used to assemble the outer wooden mold 6 of the wall is the second size, and the first size and the second size are different.
[0074] Figure 6 A longitudinal section view of a wooden formwork and a steel reinforcement cage for a wall, provided as an embodiment of the present invention, is shown below. Figure 6 Gaps 13 are provided between the wall reinforcement cage 11 and the wooden formwork 5 inside the wall and the wooden formwork 6 outside the wall.
[0075] Understandably, concrete can be poured into the steel cage 11 in the wooden formwork of the wall. The gap 13 allows the steel cage 11 of the wall to be completely covered by concrete, so that the steel cage 11 is not exposed on the wall surface, ensuring the smoothness of the wall surface.
[0076] Figure 7 This is a cross-sectional schematic diagram of the external wooden formwork provided in an embodiment of the present invention. See also: Figure 7 The top of the wooden formwork 6 outside the wall includes a pouring port 14. Concrete can be poured into the wooden formwork through the pouring port 14 to form an arc-shaped inclined concrete structural wall. For example, a pouring port 14 is provided at every 1.5m interval on the top of the wooden formwork 6 outside the wall, and the size of the pouring port 14 can be 30cm*50cm.
[0077] Figure 8 This is a schematic diagram of a tongue-and-groove wooden mold provided in an embodiment of the present invention. See also: Figure 8 The top plate 2 is shaped by the top plate wooden mold 15, and the edge of the top plate wooden mold 15 is provided with tongue and groove wooden mold 16.
[0078] After the tongue and groove wooden mold 16 is set up, the column 3 and the top plate 2 are poured. After the pouring is completed, there will be a recessed structure (i.e., tongue and groove) at the junction of the top plate 2 and the wall. After the wall is poured, the tongue and groove and the protruding structure of the wall are equivalent to a tenon joint (i.e. there is no gap). When liquid (e.g., rainwater) flows through the tongue and groove, it cannot seep into the interior of the wall, thus avoiding the leakage of liquid from the wall.
[0079] Figure 9 This is a schematic diagram of the arc-shaped measuring tool provided in an embodiment of the present invention. See also: Figure 9 The arc-shaped measuring tool 7 includes a crossbar 17 and a ruler 18; multiple openings 19 are spaced apart on the crossbar 17, and the ruler 18 is set in the openings 19.
[0080] The length of the crossbar 17 can be 1m. The number of rulers 18 can be 9. The 9 rulers 18 are installed in the openings 19 that are equally spaced on the crossbar 17. For example, the interval can be 10cm.
[0081] In practice, firstly, a bubble level is installed on the upper surface of the curved measuring tool 7, with the bubble positioned at the highest point of the container. Secondly, the two ends of the horizontal bar 17 of the curved measuring tool 7 are pressed against the wall. Then, the ruler 18 is pushed until its head contacts the wall. Finally, the reading of the ruler 18 is recorded; this reading represents the chord height within the 1m range of the horizontal bar 17. This chord height is compared with the theoretical chord height of the wall to determine if the wall construction is accurate. If inaccurate, the areas with errors are locally repaired and polished to ensure the wall's curvature meets design requirements.
[0082] It is understandable that when the size of the base plate 1 is larger than the size of the top plate 2, the longitudinal section of the building composed of the base plate 1, the curved inclined concrete structural wall, and the top plate 2 is an isosceles trapezoid with a larger base and a smaller top; when the size of the base plate 1 is smaller than the size of the top plate 2, the longitudinal section of the building composed of the base plate 1, the curved inclined concrete structural wall, and the top plate 2 is an isosceles trapezoid with a smaller base and a larger top.
[0083] Figure 10 The flowchart of the construction re-testing method for the curved inclined concrete structural wall provided by the present invention includes the following steps:
[0084] Step S1: Pouring of base slab 1;
[0085] Step S2, pouring of column 3, and then pouring of top plate 2 on top of column 3;
[0086] Step S3: Sequentially set the external support frame 10 of the external wooden formwork 6, the reinforcing keel 9 of the external wooden formwork 6, and the external wooden formwork 6;
[0087] Step S4: Use the arc-shaped measuring tool 7 to remeasure the wooden mold 6 outside the wall;
[0088] Step S5: If the chord height of the external wooden formwork 6 is consistent with the theoretical chord height of the curved inclined concrete structural wall, then the wall reinforcement cage 11 and the internal wooden formwork 5 are set in sequence; if they are inconsistent, then after adjusting the setting position of the external wooden formwork 6, step S4 is executed until the chord height of the external wooden formwork 6 is consistent with the theoretical chord height.
[0089] Step S6: Use the arc-shaped measuring tool 7 to re-measure the wooden mold 5 inside the wall;
[0090] Step S7: If the chord height of the wooden formwork 5 inside the wall is consistent with the theoretical chord height, then install the screw rod 8 and the reinforcing keel 9 of the wooden formwork 5 inside the wall in sequence; if they are inconsistent, then adjust the setting position of the wooden formwork 5 inside the wall and execute step S6 until the chord height of the wooden formwork 5 inside the wall is consistent with the theoretical chord height.
[0091] Step S8: Construction of the curved inclined concrete structural wall;
[0092] Step S9: Remove the wooden formwork inside the wall 5, the wooden formwork outside the wall 6, and the external support frame 10;
[0093] Step S10: Conduct a third remeasurement of the curved inclined concrete structural wall to determine whether the chord height of the curved inclined concrete structural wall is consistent with the theoretical chord height.
[0094] The construction verification method for arc-shaped inclined concrete structural walls provided by this invention includes the following detailed steps:
[0095] Step P1: Determine the position of the base plate 1 of the curved inclined concrete structural wall.
[0096] Among them, the position of the bottom plate 1 includes the center of the circle, the radius, and the arc formed by drawing an arc with the radius around the center of the circle.
[0097] It should be noted that before constructing the arc-shaped inclined concrete structure wall, the position of the bottom plate 1 of the arc-shaped inclined concrete structure wall can be designed. Specifically, the center coordinates and radius of the bottom plate 1 of the arc-shaped inclined concrete structure wall can be designed.
[0098] When constructing the arc-shaped inclined concrete structure wall, a total station can be used to find the point where the center of the bottom plate 1 is located and set this point as a fixed point. Then, with the fixed point as the center of the circle on the base layer (side wall rock), draw an arc along the designed radius to obtain the lower edge line of the arc-shaped inclined concrete structure wall (the pouring cut-off plane when pouring concrete for the bottom plate 1 of the arc-shaped inclined concrete structure wall, and this cut-off plane is the bottom plate 1 of the arc-shaped inclined concrete structure wall).
[0099] Step P2: Pour concrete to form the bottom plate 1 of the arc-shaped inclined concrete structure wall.
[0100] The specific process is as follows:
[0101] First, tie the bottom plate steel bars and column steel bars below the lower edge line of the arc-shaped inclined concrete structure wall, and make the tied bottom plate steel bars parallel to the lower edge line of the arc-shaped inclined concrete structure wall. The height of the column steel bars exceeds the lower edge line of the arc-shaped inclined concrete structure wall (that is, exceeds the upper part 'one' of the character 'tu').
[0102] Then pour concrete to form the bottom plate 1 of the arc-shaped inclined concrete structure wall. After pouring, nail a circle of arc-shaped wooden strips along the lower edge line of the arc-shaped inclined concrete structure wall. The width of the arc-shaped wooden strips is 2 cm, which is convenient for subsequent positioning of the formwork installation of the arc-shaped inclined concrete structure wall (that is, secondary rib positioning).
[0103] Step P3: Pour concrete to form the top plate 2 and the column 3 of the arc-shaped inclined concrete structure wall.
[0104] The specific process is as follows:
[0105] First, erect a separable support (for example, a full hall formwork support and a post-cast strip formwork support) in the arc-shaped inclined concrete structure wall, and set the height of the support to the calibrated height (that is, the elevation).
[0106] Second, place a square plate (that is, the beam and slab structure formwork) on the support. Then, use a plumb bob to lead the center of the bottom plate to the top plate and draw an arc along the designed radius of the top plate to obtain the upper edge line of the arc-shaped inclined concrete structure wall (that is, the upper edge line of the wall body). Cut the square plate along the upper edge line of the arc-shaped inclined concrete structure wall to cut off the outer formwork of the square top plate, and obtain the position of the top plate 2 (that is, the beam and slab) of the arc-shaped inclined concrete structure wall.
[0107] Third, reinforcing bars are tied to the top and bottom of the top slab 2 (i.e., the bottom of the beam), so that after the concrete is poured for the top slab 2, the reinforcing bars at the bottom of the slab (i.e., the bottom of the beam) protrude from the concrete. At the same time, inverted "U"-shaped wooden strips are nailed to the bottom of the slab (i.e., the bottom of the beam, which is inverted "U", is joined to the bottom of the curved inclined concrete structural wall, which is convex, so that there are no gaps between the beam / slab and the wall after the concrete is poured, thus preventing liquid (e.g., rainwater) leakage). The inverted "U"-shaped wooden strips are 2cm*2cm in size. Fourth, concrete is poured to form the columns 3 and the top slab 2.
[0108] Step P4: Formwork erection for the curved inclined concrete structural wall.
[0109] The specific process is as follows:
[0110] First, remove the supports and formwork (e.g., the top slab 2 supports and top slab 2 formwork) on the inner side of the curved inclined concrete structural wall.
[0111] Second, place vertical secondary keels (i.e. steel pipes) on the outside of the curved, inclined concrete structural wall.
[0112] Third, place the horizontal main keel (i.e., reinforcing bar) on the inner side of the secondary keel towards the curved and inclined concrete structural wall. The type of reinforcing bar can be 16, where 16 indicates that the diameter of the reinforcing bar is 16mm.
[0113] Fourth, place the external wooden formwork 6, tie the reinforcing bars of the curved inclined concrete structural wall, and the internal wooden formwork 5 on the surface of the main keel in sequence. BIM can design a three-dimensional model of the curved inclined concrete structural wall, and CAD can determine the size of each small wooden block in the wooden formwork used to construct the curved inclined concrete structural wall based on the dimensions of the inner and outer arcs of the planar unfolded view (i.e., the partial annular view) of the three-dimensional model of the curved inclined concrete structural wall.
[0114] It should be noted that after the wooden formwork 6 is placed outside the wall, the material discharge port is located at a certain distance from the top of the wooden formwork 6. This distance can be 1.5m, and the dimensions of the material discharge port are 30cm x 50cm. The material discharge port is the pouring port 14 in the previous embodiment of this invention.
[0115] Step P5: Pour concrete to form an arc-shaped inclined concrete structural wall.
[0116] The specific process is as follows:
[0117] First, after placing the wooden formwork 6 outside the wall, place the external support frame 10 outside the main keel (i.e., the reinforcing bar), and place the diagonal bracing from bottom to top along the position where the horizontal bar 17 of the external support frame 10 contacts the curved inclined concrete structural wall.
[0118] Second, after the steel reinforcement of the curved inclined concrete structural wall is tied in sequence and the wooden formwork 5 inside the wall is placed, the wooden formwork 6 outside the wall and the wooden formwork 5 inside the wall can be fixed by screw rods 8.
[0119] Third, steel wire ropes can be used to tie (i.e., tie) the cast-in-place column 3 (i.e., structural column) and the junction of the horizontal and vertical bars in the external support frame 10 (i.e., the main node of the outer frame).
[0120] Fourth, install a hopper at the pre-reserved concrete pouring hole in P4 and pour concrete to form an arc-shaped inclined concrete structural wall. The external support frame 10 is placed in multiple rings around the arc-shaped inclined concrete structural wall from the inside out, with the innermost ring being the first ring. Taking the first ring as an example, each ring has multiple spaced vertical poles, and each vertical pole has multiple spaced horizontal poles. The interval between two vertical poles is 1.8m, and the interval between two horizontal poles is 900mm. The vertical poles of the external support frame 205 rings are spaced 1.5m apart. The first diagonal brace closest to the bottom surface is 200mm high, and the interval between two diagonal braces is 450mm. A steel bar is installed at the end of the diagonal brace that contacts the bottom surface to prevent slippage and maintain the stability of the arc-shaped inclined concrete structural wall during concrete pouring.
[0121] Step P6: Measurement of the chord height of the curved inclined concrete structural wall.
[0122] The specific process is as follows: After the formwork of the curved inclined concrete structural wall is removed, the chord height within a 1m chord length range of the curved inclined concrete structural wall can be measured using the curved measuring tool 7. The chord height is compared with the theoretical chord height within a 1m chord length range. If they are the same or the error is within a certain range, the constructed curved inclined concrete structural wall is considered to be accurate.
[0123] It should be noted that the curved measuring tool 7 consists of a 1m long horizontal bar 17 and nine graduated rulers 18 mounted on the horizontal bar 17, with a 10cm spacing between adjacent rulers 18. Each ruler 18 can freely extend and retract along the opening 19 on the horizontal bar 17. During the actual measurement of the curved inclined concrete structural wall, the two ends of the horizontal bar 17 of the curved measuring tool 7 can be horizontally pressed against the curved inclined concrete structural wall, and the middle ruler 18 can be pushed so that the end of the ruler 18 closest to the curved inclined concrete structural wall contacts the wall. At this point, the distance (i.e., the actual chord height) of each ruler 18 within the 1m horizontal bar 17 range from the end contacting the curved inclined concrete structural wall to the horizontal bar 17 can be read from the graduations on the ruler 18. For areas with errors, local repairs and grinding can be performed to ensure the curvature of the wall meets the design requirements.
[0124] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
