[0050] Please refer to Figure 1 In a preferred embodiment of the present application, a curved roof construction method is provided, which comprises steps S1, S2, S3, S4 and S5.

[0051] S1, establish a BIM model of the curved roof, simulate the arrangement of the support system and the wooden formwork according to the preset surface profile of the curved roof concrete bottom surface, and obtain the support height of each support position of the support system. That is, a three-dimensional BIM model of the curved roof is established according to the design, the surface profile of the curved roof concrete bottom surface in the three-dimensional BIM model is meshed and divided, so that the wooden formwork at the bottom is divided into multiple pieces and meshed and distributed, thereby forming a complete wooden formwork system. The height of the support assembly and the support inclination angle of the wooden formwork need to be set according to the position of each wooden formwork, and the support system 100 includes all support assemblies. First, simulation is performed to provide a standard basis for subsequent construction.

[0052] S2, install the corresponding support assembly according to the support height of each support position, install the steel main beam on the support assembly, install the wooden secondary beam 190 on the steel main beam 150, and fix the wooden formwork 191 on the wooden secondary beam 190, and the height and inclination angle of the wooden formwork can be adjusted to the required position. Due to ground and other installation errors on site, errors may exist between the final wooden formwork and the preset height and angle in the three-dimensional model. After pre-installation, the angle and height are adjusted to ensure that the height and inclination angle of the wooden formwork reach the preset position, thereby ensuring the shape effect of the subsequent pouring building.

[0053] S3, lay the steel mesh on the wooden formwork 191, and install the embedded part 200 on the steel mesh. The embedded part 200 is arranged in multiple groups along the longitudinal extension path of the upper surface of the preset curved roof concrete. The overall longitudinal extension path of the upper surface of the curved roof concrete is usually a path that curves downward and extends obliquely. The embedded parts 200 in the same group are arranged in multiple groups along the transverse extension path of the upper surface of the curved roof concrete. The overall transverse extension path of the upper surface of the curved roof concrete is usually a straight line or a curve.

[0054] Pour concrete on the wooden formwork 191 to form a curved roof concrete base, and the upper end of the embedded part 200 protrudes from the curved roof concrete base.

[0055] S4, install the cross beam 300 on the embedded part 200, and install the longitudinal beam 320 on the cross beam.

[0056] S5, install the insulation board 400, the waterproof board 500, the tile mounting seat 600, the tile board 700, the pressing plate 800 and the ridge strip 900 in sequence. The tile mounting seat 600 is provided with a positioning abutting structure to position the corners of the tile board 700, and the positioning abutting structure at the inclined lower end of the tile board 700 can support the tile board 700; the pressing plate 800 presses the tile board 700 in cooperation with the tile mounting seat.

[0057] By establishing a BIM model of the curved roof, the surface profile data of the concrete base surface of the curved roof is accurately obtained, and the support system 100 (support assembly) and the wooden formwork are arranged accordingly, realizing the precise presetting of the height and angle of the support assembly. The support assembly with adjustable height and inclination angle and the wooden formwork 191 can flexibly adapt to the changes of the curved surface at different positions of the curved roof, avoiding the problem of fixed support system in traditional construction, and improving the versatility and adaptability of the formwork support system. By arranging the embedded parts 200 on the reinforcement mesh and making the upper end protrude from the concrete base, a firm connection foundation is provided for the subsequent installation of the horizontal and vertical keels 300 and 320. The embedded parts 200 are arranged in an orderly manner along the longitudinal and transverse directions of the curved roof, ensuring the overall stability and load-bearing capacity of the keel system. The positioning and abutting structure provided on the tile mounting seat 600 can accurately position the corners of the tile 700, and the positioning and abutting structure at the inclined lower end can also support the tile, preventing the tile from sliding or mispositioning and improving the installation efficiency. In combination with the pressing plate, the installation stability and wind resistance of the tile on the curved roof are significantly improved.

[0058] In the specific embodiments of the present application, the concrete is poured on the wooden formwork to form the curved roof concrete base, specifically including: dividing the reinforcement mesh into multiple segments along the longitudinal inclined extension path of the preset curved roof concrete, and setting an intercepting net at the bottom end of each segment of reinforcement mesh, starting from the lowest segment of reinforcement mesh, pouring the concrete in sequence from bottom to top, forming the curved roof concrete base, and setting a baffle at the bottom end of the lowest segment of reinforcement mesh. By dividing the reinforcement mesh into multiple segments along the longitudinal inclined extension path of the curved roof, and setting an intercepting net at the bottom end of each segment of reinforcement mesh, the concrete is poured in sequence from bottom to top, effectively controlling the flow range of the concrete on the inclined surface, preventing the concrete from sliding or accumulating unevenly. This segmented pouring method not only improves the precision of concrete molding, but also significantly improves the construction quality. The concrete needs to be vibrated during pouring to ensure the quality of concrete molding.

[0059] In specific embodiments of the present application, before pouring each section of the steel bar mesh, the corresponding cross-beam 300 of the section of the steel bar mesh is positioned and matched with the embedded part 200. When there is a deviation in the embedded part 200, the position of the embedded part 200 can be adjusted until it is positioned and matched with the cross-beam 300. After all the embedded parts 200 are positioned and matched with the cross-beams 300, the concrete is poured. Before pouring each section of the steel bar mesh, the corresponding cross-beam 300 of the section of the steel bar mesh is positioned and matched with the embedded part 200. When it is found that there is a deviation in the position of the embedded part 200, the position of the embedded part 200 is adjusted in time to ensure that all the embedded parts 200 are precisely docked with the cross-beams 300 before pouring the concrete. This step effectively avoids the difficulty in installing the cross-beam 300 due to the position error of the embedded part 200. After the concrete solidifies, if other operations need to be performed on the surface of the concrete, such as maintenance, the cross-beam 300 can be removed for convenience, but it can also not be removed, only the cross-beam 300 needs to be avoided.

[0060] Specifically, the embedded part is installed on the steel bar mesh, specifically including: the plurality of L-shaped legs at the bottom of the embedded part 200 are tied and fastened on the steel bars on the steel bar mesh by iron wire. The embedded part 200 can be welded with a plurality of L-shaped legs, and the L-shaped legs are tied and fastened on the steel bars by iron wire, thereby realizing the pre-embedded installation of the embedded part 200. This can effectively prevent the embedded part 200 from being displaced during pouring, ensuring the accuracy of the position of the embedded part 200 and providing reliable protection for the subsequent installation of the cross-beam system.

[0061] Referring to Figure 13 In some embodiments of the present application, the embedded part 200 includes a pre-embedded section 210 and a positioning section 220; the bottom of the pre-embedded section 210 is embedded in the roof concrete, and the upper end of the pre-embedded section 210 protrudes out of the roof concrete; the cross section profile of the positioning section 220 is smaller than that of the upper end of the pre-embedded section 210; the cross-beam 300 is provided with a positioning hole 310, and the profile of the positioning hole 310 is larger than that of the positioning section 220, that is, the diameter of the upper end of the pre-embedded section 210, the diameter of the positioning hole 310, and the diameter of the positioning section 220 decrease in turn. The profile of the positioning hole 310 is larger than that of the positioning section 220, so that there is a larger gap redundancy during installation, so that the positioning section 220 can be embedded in the positioning hole 310 without complete alignment, so that a certain installation or manufacturing error can be allowed, and the installation is more smooth. The bottom surface of the cross-beam 300 is in contact with the upper end of the pre-embedded section 210 to support the cross-beam 300. When the concrete pouring is completed and the cross-beam 300 does not need to be removed, in step S4, the cross-beam 300 is installed on the embedded part 200, specifically referring to connecting and fixing the bottom surface of the cross-beam 300 and the upper end of the pre-embedded section 210 by fasteners or welding.

[0062] In specific embodiments of the present application, step S4 specifically includes:

[0063] S41, place the cross-beam 300 on the upper end of the embedded section 210 of the corresponding embedded part 200, and embed the positioning section 220 at the upper end of the embedded part 200 into the corresponding positioning hole 310 of the cross-beam 300. Thus, the cross-beam 300 is positioned on the embedded part 200 Figure 7 as shown in the state.

[0064] If the cross-beam 300 is placed when the embedded part 200 is positioned, the action can not be repeated.

[0065] S42, weld the cross-beam 300 at the contact position with the embedded part 200.

[0066] S43, place the longitudinal-beam 320 at the corresponding position and fix the bottom with the cross-beam 300. The longitudinal-beam 320 and the cross-beam 300 can be fixed by the connecting block, and the upper and lower ends of the connecting block are welded with the longitudinal-beam 320 and the cross-beam 300, respectively. Of course, the connection mode of the longitudinal-beam 320 and the cross-beam 300 can also be other, such as processing the hole position and installing the fastener to fix.

[0067] After step S43, it further includes the step: S44, connecting the reinforcing rod 330 between the adjacent longitudinal-beams 320, and welding and fixing the reinforcing rod 330 at both ends with the longitudinal-beams 320 on both sides, to achieve Figure 8 the state as shown. Thus, the longitudinal-beams 320 are connected in series to strengthen the structural strength of the whole metal frame.

[0068] Referring to Figures 2 to 6 in some embodiments of the present application, step S2 specifically includes steps S21, S22, S23, S24, S25 and S26.

[0069] S21, assemble the support vertical frame 110 at the corresponding position, and install the cross-bar 111 between the adjacent support vertical frames 110. Generally, four rectangular distributed support vertical frames 110 are needed for one piece of wooden template. The adjacent support vertical frames 110 are fixed in series by the cross-bar 111 to ensure the posture stability of the support vertical frame 110.

[0070] S22, install the connecting cylinder 120 at the upper end of the support vertical frame 110. The support vertical frame 110 includes a plurality of vertically spliced support bars 112, and the upper end of the support bar 112 is provided with a butt joint expansion pipe 113. The bottom of the upper support bar 112 is inserted into the adjacent butt joint expansion pipe 113 below. The butt joint expansion pipe 113 and the bottom of the support bar 112 are provided with hole positions so that when the upper and lower adjacent support bars 112 are spliced, they can be fixed by fasteners. The connecting cylinder 120 is inserted into the butt joint expansion pipe 113 of the uppermost support bar 112. Thus, the positioning and installation of the connecting cylinder 120 are realized. The connecting cylinder 120 is provided with hole positions to align with the hole positions of the butt joint expansion pipe 113 of the uppermost support bar 112 and be fixed by fasteners. The fasteners can be bolts and nuts.

[0071] S23, install the lifting adjusting rod 130 and the main batten support plate 140. The lifting adjusting rod 130 is installed on the upper end of the connecting cylinder 120 and can be adjusted in position relative to the connecting cylinder 120. The main batten support plate 140 is installed on the upper end of the lifting adjusting rod 130, and the main batten support plate 140 has an upper opening and a through support groove 141.

[0072] S24, place the steel main batten 150 on the main batten support plate 140 and fix the steel main batten 150, which is embedded in the support groove 141. The secondary batten support plate 160 is rotatably installed on the steel main batten 150, the support adjusting member 170 is installed on the main batten support plate 140, and the second side plate 161 extending upward is arranged on both sides of the secondary batten support plate 160. The second side plate 161 is provided with a pin hole 162 and a third threaded hole 163.

[0073] S25, place the wooden secondary batten 190 on the secondary batten support plate 160 between the two second side plates 161, and screw a fixing screw into the third threaded hole 163 to fix the wooden secondary batten 190. Then, a steel nail is screwed into the pin hole 162 and is inserted into the wooden secondary batten 190, so as to further reinforce the wooden secondary batten 190 and avoid loosening caused by the fixing screw, thereby ensuring the stability of the support.

[0074] S26, adjust the height and angle of the secondary batten support plate 160 to achieve coarse adjustment, then fix the wooden template 191 on the wooden secondary batten 190, and adjust the height and angle of the wooden template 191, so as to ensure that the wooden template 191 reaches the appropriate position. Thus, the position adjustment of the wooden template 191 is realized through two adjustments.

[0075] Specifically, step S26 specifically includes steps S261, S262, S263 and S264.

[0076] S261, place the wooden template 191 on the wooden secondary batten 190. If the position of the wooden template 191 meets the requirements, no adjustment is needed. Usually, there will be installation errors, so the lifting adjusting rod 130 needs to be rotated to adjust the height of the secondary batten support plate 160 and the wooden secondary batten 190 on the secondary batten support plate 160. The adjustment is continued until the position of the wooden template 191 meets the requirements when the wooden template 191 is placed on the wooden secondary batten 190, and then the coarse adjustment is completed.

[0077] S262, rotate the support adjusting member 170 to adjust the pitch angle of the secondary batten support plate 160.

[0078] S263, the wood template is connected and fixed with the wood batten, and the wood strip 192 is embedded between the bottom edge of the wood template 191 and the wood batten 190. Generally, when the wood template 191 is placed on the wood batten 190 to the appropriate position, the two are connected and fixed by using nails, and the edge embedded with the wood strip 192 ensures that the raised edge of the wood template 191 can be effectively supported, so that after the concrete is poured, no obvious deformation will occur. The wood strip 192 can be reinforced by nailing the nails.

[0079] S264, at this time there may still be some deviation, and the height and angle of the wood template 191 are adjusted to the required position by fine-tuning the screwing of the lifting and adjusting rod 130 and the support adjusting piece 170. Thus, the height and angle of the wood template 191 are adjusted so that it can be adjusted to the required position according to the current installation condition. The multi-stage adjustment mechanism enables the template system to accurately match the geometric shape of the curved roof, avoiding the rework problem caused by the mismatch of the height and angle of the template in traditional construction, and significantly improving the construction efficiency and forming quality.

[0080] The structure of the support assembly will be described in detail below Figures 2 to 6 to make it understand the above steps.

[0081] The support assembly includes a support vertical frame 110, a connecting cylinder 120, a lifting and adjusting rod 130, a main batten supporting plate 140, a steel main batten 150, a secondary batten supporting plate 160, and a support adjusting piece 170.

[0082] As shown in Figure 5 , generally, two wood battens 190 are arranged at the bottom of a wood template 191, and two support points are needed for each wood batten 190, so four support vertical frames 110 are needed for one wood template 191. The secondary batten supporting plate 160 is installed on the steel main batten 150 along the horizontal axis.

[0083] The support adjusting piece 170 is installed on the main batten supporting plate 140 and can be adjusted up and down relative to the main batten supporting plate 140. The upper end of the support adjusting piece 170 abuts against the secondary batten supporting plate 160 to support the secondary batten supporting plate 160, so that the support of the secondary batten supporting plate 160 with different inclination angles is realized through the up and down adjustment of the support adjusting piece 170.

[0084] In the prior art, a wooden wedge is inserted between the main batten supporting plate 140 and the wood batten 190, and the wooden wedge is connected and fixed with the wood batten 190 through a nail to realize the stable support of the wood batten 190 by the main batten supporting plate 140, but this way makes the inclination angle of the wood batten 190 not adjustable, and adjustment may also need to replace wooden wedges of different specifications or embed additional wooden wedges, which makes adjustment troublesome and may need multiple repeated adjustments. The present application realizes flexible adjustment of the height of the formwork support through the cooperation of the lifting adjusting rod 130 and the connecting cylinder 120. At the same time, the secondary batten supporting plate 160 can rotate along the horizontal axis and can adapt to the inclination angle of the wood batten 190 at the bottom of the wood formwork 191 at different positions of the curved roof. It can be understood that, due to the inclination angle of the wood batten 190, the height of the main batten supporting plate 140, the steel main batten 150 and the secondary batten supporting plate 160 on the supporting vertical frame 110 has a difference, which can be realized by the lifting adjustment of the lifting adjusting rod 130, and if the height difference is too large, different lengths of the connecting cylinder 120 can also be used to expand the height difference.

[0085] Specifically, the connecting cylinder 120 is provided with a first threaded hole 121 in the center, and the lifting adjusting rod 130 is threadedly connected to the first threaded hole 121 to realize lifting adjustment by rotation, and the main batten supporting plate 140 can rotate relative to the lifting adjusting rod 130. The main batten supporting plate 140 can rotate relative to the lifting adjusting rod 130, so that the main batten supporting plate 140 can not rotate with the lifting adjusting rod 130 under the condition that the lifting adjusting rod 130 rotates, thereby not being affected by the rotation of the lifting adjusting rod 130.

[0086] The main rib supporting plate 140 is installed on the lifting adjusting rod 130 by a limiting screw 180. The upper end of the lifting adjusting rod 130 is provided with a second threaded hole 131, and the limiting screw 180 comprises a threaded section 181, a cylindrical section 182 and a limiting head 183. The threaded section 181 is threadedly connected to the second threaded hole 131, the cylindrical section 182 is arranged at the upper end of the threaded section 181, and the limiting head 183 is arranged at the upper end of the cylindrical section 182. The diameters of the threaded section 181, the cylindrical section 182 and the limiting head 183 increase in sequence. The cylindrical section 182 is adapted in diameter to the circular hole 143, and the cylindrical section 182 is usually in clearance fit with the circular hole 143. The main rib supporting plate 140 comprises a horizontal plate 142, and the horizontal plate 142 is provided with the circular hole 143 sleeved on the cylindrical section 182. The horizontal plate 142 is located between the limiting head 183 and the upper end of the lifting adjusting rod 130 and can rotate and move around the cylindrical section 182. The cylindrical section 182 and the limiting head 183 enable the main rib supporting plate 140 to be stably sleeved on the cylindrical section 182 and to rotate and move between the limiting head 183 and the upper end of the lifting adjusting rod 130. The limiting head 183 does not directly press the main rib supporting plate 140, but only plays a vertical limiting role. The horizontal plate 142 is provided at the upper end of the circular hole 143 with a countersunk groove 144 for embedding the limiting head 183. The countersunk groove 144 provided at the upper end of the circular hole 143 of the horizontal plate 142 enables the limiting head 183 of the limiting screw 180 to be better embedded therein, thereby avoiding the limiting head 183 protruding from the upper surface of the horizontal plate 142 and contacting the steel main rib 150, which causes unstable support.

[0087] The horizontal plate 142 is provided with side plates 145 on both sides, and the horizontal plate 142 and the side plates 145 define a supporting groove 141. The side plates 145 on both sides are threadedly connected with clamping screws 146, and the clamping screws 146 on both sides are used for clamping the steel main rib 150. Through the clamping action of the clamping screws 146, the steel main rib 150 can be firmly fixed in the supporting groove 141 of the main rib supporting plate 140. The clamping screws 146 enable the main rib supporting plate 140 to adapt to steel main ribs 150 of different sizes and also adjust the fixed position of the main rib supporting plate 140 in the width direction, thereby improving the versatility and flexibility of the formwork supporting system. One of the side plates 145 is provided with a transverse plate 147 extending outwardly and horizontally, and the support adjusting member 170 is a vertical screw rod threadedly connected to the transverse plate 147. The support adjusting member 170 can be flexibly adjusted in lifting, thereby quickly adapting to the angle change of the secondary rib supporting plate 160.

[0098] The waterproof board 500 is provided with an inner wrapping portion at one end to directly wrap the longitudinal keel 320, and is provided with an outer wrapping portion at the other end to wrap the inner wrapping portion of the adjacent waterproof board 500. When installed, the outer wrapping portion can wrap the inner wrapping portion at the connection of the adjacent waterproof boards 500, so that the waterproof effect at the connection of the longitudinal keel 320 and the waterproof board 500 is better.

[0099] Specifically, the tile mounting seat 600 includes a wrapping portion 610 that wraps the longitudinal keel 320 and the waterproof board 500 on the longitudinal keel 320, that is, the wrapping portion 610 wraps the longitudinal keel 320 and the inner wrapping portion and the outer wrapping portion on the longitudinal keel 320, and the wrapping portion 610, the longitudinal keel 320 and the waterproof board 500 are provided with corresponding hole positions to be connected and fixed by fasteners. The upper middle portion of the wrapping portion 610 is provided with a convex strip 620, and the positioning abutting structure is a convex positioning block 630 provided in the middle portion of the convex strip 620, that is, the middle portion of the convex strip 620 is provided with a convex positioning block 630. The bottom of the tile 700 is carried on the upper end of the wrapping portion 610, and the corners of the tile 700 are provided with notches 710 adapted to the positioning block 630, so that the positioning block 630 is embedded in the notch 710, and the positioning of the four corners of the tile 700 is realized.

The bottom of the pressing plate 800 is provided with a vertical strip 810 penetrating the extension opening 650, and the bottom of the vertical strip 810 is provided with a limiting strip 820 embedded in the clamping groove 640, and the width of the limiting strip 820 is greater than that of the extension opening 650, so that the limiting strip 820 cannot pass through the extension opening 650 to separate from the clamping groove 640. Generally, the width of the clamping groove 640 and the limiting strip 820 is matched, the clamping groove 640 is used for positioning and limiting the limiting strip 820, and the pre-positioning of the pressing plate 800 during installation is realized. The two sides of the pressing plate 800 are provided with protruding pressing blocks 830, and the pressing blocks 830 are used for pressing the tile 700.

Therefore, during the installation process, the pressing blocks 830 can press the tile 700, so as to avoid contacting the upper end of the wrapping part 610 through the pressing plate 800, thereby applying most of the pressing force to the upper end of the wrapping part 610, so as to ensure the pressing effect. The clamping groove 640 is provided with an opening at one end, and the other end is provided with an end wall for abutting against the limiting strip 820, so as to realize the positioning of the pressing plate 800, and facilitate the alignment of the hole position and the installation of the screw. Generally, self-tapping screws are used to install the pressing plate 800, and since the roof is usually inclined to one side, the end wall of the clamping groove 640 is usually abutted against the inclined lower end of the limiting strip 820, that is, when the end wall of the clamping groove 640 is abutted against the limiting strip 820, it also plays a role in supporting the inclined limiting strip 820, so that the placement is more stable, and it is not necessary to hold the pressing plate 800 with hands to install the screw. During installation, the limiting strip 820 is clamped into the clamping groove 640 until it is abutted against the end wall of the clamping groove 640, and the pre-positioning of the pressing plate 800 is realized by the limiting of the end wall and the positioning of the clamping groove 640 and the limiting strip 820, so that the position is stable, the hole position is aligned, and the subsequent installation of the screw is facilitated.
