Description

Technical Field

[0001] The invention relates to the technical field of concrete forming formwork, in particular to a concrete supporting formwork for sliding membrane construction and a construction process. Background Art

[0002] The supporting formwork for concrete pouring is a key part to ensure the formation and stability of the concrete structure. The supporting formwork should be easy to remove and reinstall so that the formwork can be cleaned and reused after the concrete pouring is completed. In sliding membrane construction, the formwork system is used to form the shape and size of the concrete, and the lifting system is responsible for sliding the formwork system along the concrete surface. The formwork system can be used for concrete pouring and shaping.

[0003] Most existing formwork systems can be adjusted according to the size of the concrete to be formed during installation, and fixed after adjustment. For example, in a formwork support system for a special-shaped precast concrete component disclosed in the existing patent announcement number CN116714081B, it includes a ground beam, a formwork, and a support structure for supporting the formwork. The formwork includes a bottom formwork arranged at the top of the ground beam, and both sides of the bottom formwork are provided with bottom side forms arranged along its length direction. There is a height difference between the bottom side forms, and the height of the bottom side forms can be adjusted; the top of the bottom side formwork is fixed with a side formwork that is horizontally perpendicular to the outer wall of the bottom side formwork; the side formwork is vertically provided with a middle side formwork with adjustable horizontal position, and the top of the middle side formwork can be detachably connected with a horizontally arranged cover plate, and the opposite ends of the cover plate are detachably connected with a top side formwork, which can be adjusted and supported to facilitate the detachment of the component after forming.

[0004] In the construction of sliding membrane, the circle and inner mold of the supporting formwork can indeed be adjusted according to the size, but the fixed formwork is not easy to adjust again. When the concrete is formed and the lifting operation is performed, when the formwork is in close contact with the concrete, the friction between the concrete and the formwork will hinder the lifting of the formwork, increasing the difficulty of lifting the formwork. For this reason, a concrete supporting formwork and construction process for sliding membrane construction are proposed. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 9 In an embodiment of the present invention, a concrete support formwork for sliding membrane construction includes a lifting frame 1; an operating platform system for sliding membrane construction is installed on both sides of the lifting frame 1; the operating platform system facilitates subsequent construction operations, such as pouring concrete into the support formwork; a hydraulic system for control is installed on the operating platform system;

[0049] A first enclosure plate 2 and a second enclosure plate 3 arranged on the inner side of the lifting frame 1;

[0050] A support mechanism 4 for mounting the first enclosure plate 2 or the second enclosure plate 3 on the lifting frame 1, wherein the support mechanism 4 is mounted on the side away from the first enclosure plate 2 and the second enclosure plate 3;

[0051] A first template body 6 is arranged on the side of the first enclosure plate 2 close to the second enclosure plate 3, and the first template body 6 is rotatably connected to the side molds 7 on both sides. A tensioning mechanism 8 for adjusting the rotation position of the side mold 7 is installed on one side of the first enclosure plate 2, and a transmission mechanism 9 driven by the movement of the first template body 6 is installed on the side of the first enclosure plate 2 away from the first template body 6, and is used to drive the tensioning mechanism 8 to work;

[0052] A second template body 5 is arranged on the side of the second circle plate 3 close to the first circle plate 2, one side of the second template body 5 is connected to a sliding column 10 that is slidably matched with the first circle plate 2, and a distance adjustment mechanism 11 for adjusting the horizontal position of the second template body 5 is installed on the second circle plate 3;

[0053] A centering adjustment mechanism 15 connected to the top of the first template body 6 and the second template body 5 is used to drive the first template body 6 to move toward each other synchronously when the second template body 5 moves; and

[0054] The limiting mechanism 12 installed on the lifting frame 1 is used to limit the adjustment range of the centering adjustment mechanism 15;

[0055] By adopting the above scheme, the second formwork body 5 corresponds to the first formwork body 6 and the side formwork 7, and the concrete is formed between the first formwork body 6, the side form box and the second formwork body 5. After forming, before the formwork is lifted, the external hydraulic system controls the distance adjustment mechanism 11 to adjust the second formwork body 5 away from the formed concrete, and through the linkage of the centering adjustment mechanism 15, the first formwork body 6 is driven to move toward each other synchronously. At the same time, when the first formwork body 6 is away from the formed concrete and close to the first circle plate 2, the tensioning mechanism 8 is driven to work through the transmission mechanism 9, and the side formwork 7 is adjusted to rotate toward the side of the first circle plate 2. The supporting formwork is lifted by the lifting system to reach the target position to reset the first formwork body 6 and the second formwork body 5, and then the next layer of concrete is formed.

[0056] Furthermore, Figure 1 As shown, it also includes a hydraulic jack 13 installed on the top of the lifting frame 1, which is used for climbing the lifting system during the synovial construction. Under the control of the hydraulic system, the hydraulic jack 13 moves upward along the support rod used for climbing the synovial. The hydraulic control console in the hydraulic system is the power source, which provides power to the hydraulic jack 13 through components such as an oil pump, an oil tank, and a control valve.

[0057] like Figure 3As shown, the support mechanism 4 includes a support screw 401; a seat plate 402 connected to one end of the support screw 401, which is fixed to the first enclosure plate 2 or the second enclosure plate 3 by bolts; an L-shaped fixing seat 403 connected to the lifting frame 1, which is provided with a strip hole 404 for inserting the rod body of the support screw 401; and two sets of locking sleeves 405 threadedly connected to the support screw 401, and both sides of the strip hole 404 are provided with locking sleeves 405 in contact with the L-shaped fixing seat 403;

[0058] Specifically, at least four sets of seat plates 402 are connected to the sides away from the first enclosure plate 2 and the second enclosure plate 3, and an L-shaped fixing seat 403 is pre-fixed on the lifting frame 1. According to the size of the concrete at the pouring position, the horizontal position of the supporting screw 401 is adjusted to ensure that the size is adjusted in place, and the locking sleeve 405 is stably connected to fix the position of the first enclosure plate 2 or the second enclosure plate 3. In actual use, the first enclosure plate 2 or the second enclosure plate 3 can also be laid according to the pre-tied steel bars.

[0059] like Fig. 9 As shown, the tensioning mechanism 8 includes an oblique support rod 801 hinged on the side of the side mold 7 close to the first enclosure plate 2; a guide plate 802 hinged on the end of the oblique support rod 801 away from the side mold 7, which is slidably arranged on the side of the first enclosure plate 2; a guide hole 803 is provided on the side of the first enclosure plate 2, and a guide block slidably matched with the guide hole 803 is connected to one side of the guide plate 802; a linkage rack 804 connected to the side close to the two groups of guide plates 802; and a large gear 805 meshed between the two groups of linkage racks 804, the shaft end of the large gear 805 away from the side of the first template body 6 is connected to the rotating shaft, and the rotating shaft is rotatably matched with the first enclosure plate 2;

[0060] Specifically, Fig. 9 As shown, with the side of the first enclosure plate 2 close to the first formwork body 6 as the viewing side, when the large gear 805 rotates counterclockwise, the two sets of linked racks 804 approach each other, which will drive the two sets of guide plates 802 to approach each other, and drive the side form 7 to flip toward the side close to the first enclosure plate 2 through the diagonal support rod 801. In actual use, since the first enclosure plate 2 and the first formwork body 6 are arranged in the molding construction of the silo structure, the first enclosure plate 2 and the first formwork body 6 are located on the inner side of the ring. When moving away from the side of the molding concrete, if the size is fixed, adjacent formworks will be interfered with. The inward retraction of the side formwork 7 when the first formwork body 6 moves can avoid interference, reduce the process of disassembly and reinstallation of the formwork, and facilitate subsequent continuous cycle operations.

[0061] like Figure 8 and Fig. 9As shown, the transmission mechanism 9 includes a worm gear 901 arranged on the side of the first circle plate 2 away from the first template body 6, and its shaft end is connected to the end of the rotating shaft away from the large gear 805; two groups of support blocks 902 fixedly connected to the side of the first circle plate 2 away from the first template body 6; a worm 903 rotatably mounted on the support block 902 and meshing with the worm gear 901; pinions 904 mounted on both ends of the worm 903; a toggle rack 905 mounted on the side of the first template body 6 close to the first circle plate 2 and meshing with the pinion 904; and a through hole 906 arranged on the first circle plate 2 for stable sliding of the toggle rack 905;

[0062] Specifically, referring to the structural setting in the attached drawings, the worm 903 can be a left-handed worm, so that when the first template body 6 approaches the first circle plate 2, the rack 905 is turned to drive the worm 903 to rotate, and at this time the worm wheel 901 is driven, and the large gear 805 rotates counterclockwise as mentioned above, that is, when the first template body 6 approaches the first circle plate 2, the side mold 7 is retracted; conversely, when the first template body 6 is reset away from the first circle plate 2, the side mold 7 is reset.

[0063] like Figure 7 As shown, the distance adjustment mechanism 11 includes an adjustment box 1101 installed on the side of the second circle plate 3 away from the second template body 5; a second movable rod 1102 connected to the side of the second template body 5 close to the second circle plate 3 and sliding through the second circle plate 3 to extend into the adjustment box 1101; an adjustment cavity A1103 arranged in the adjustment box 1101; a second oil pipe 1104 connected to the adjustment box 1101 and connected to the adjustment cavity A1103; a plate plug 1105 connected to the end of the second movable rod 1102 and slidingly matched with the inner wall of the adjustment box 1101; an adjustment cavity B1106 arranged on the side of the plate plug 1105 away from the adjustment cavity A1103; and a second spring 1107 arranged in the adjustment cavity B1106 and sleeved on the second movable rod 1102;

[0064] Specifically, the second oil pipe 1104 can be connected to the hydraulic system in the sliding membrane construction. When the concrete in the supporting formwork is formed, part of the oil in the adjusting chamber A1103 is extracted. At the same time, under the elastic force of the second spring 1107, the plate plug 1105 slides toward the side close to the adjusting chamber A1103, and the sliding column 10 slides on the second circle plate 3. The second formwork body 5 moves toward the side close to the second circle plate 3. It should be noted that in actual operation, there is no need to control the second formwork body 5 to move too much distance, mainly to reduce friction and collision during the lifting process.

[0065] like Figure 5As shown, the limiting mechanism 12 includes a limiting platform 1201 arranged on the top of the first enclosure plate 2 and the second enclosure plate 3; a fixed plate 1202 connected to the lifting frame 1; a sleeve 1203 connected to the bottom of the fixed plate 1202, one side of the sleeve 1203 is connected to the first oil pipe 1204, and the second oil pipe 1104 and the first oil pipe 1204 are connected through the hydraulic oil circuit 14; a floating cavity A1205 arranged in the sleeve 1203; a round plug 1206 slidably arranged in the sleeve 1203, and the side of the round plug 1206 away from the floating cavity A1205 is connected with a first movable rod 1207 that slides out of the bottom of the sleeve 1203 and is connected to the top of the limiting platform 1201; a floating cavity B1208 arranged on the side of the round plug 1206 away from the floating cavity A1205; and a first spring 1209 arranged in the floating cavity B1208 and sleeved on the first movable rod 1207;

[0066] The hydraulic oil circuit 14 is connected to the hydraulic system. The hydraulic system controls the flow of oil in the hydraulic oil circuit 14, thereby controlling the limit mechanism 12 and the distance adjustment mechanism 11 to work, without the need to arrange multiple control components.

[0067] Specifically, part of the oil in the floating chamber A1205 is extracted, and at the same time, the round plug 1206 moves upward under the elastic force of the first spring 1209, and the limit platform 1201 is driven to move upward through the first movable rod 1207. The limit platform 1201 moves up to the top of the two groups of fork rods 1503 without affecting the movement of the two groups of fork rods 1503.

[0068] Furthermore, the limiting mechanism 12 also includes an extension rod 1210 connected to the bottom of the fixed plate 1202; and a limiting sleeve rod 1211 slidably sleeved on the outside of the extension rod 1210 and with the bottom end connected to the top of the limiting platform 1201; when the limiting platform 1201 moves, the extension rod 1210 slides in the limiting sleeve rod 1211, so that the limiting platform 1201 moves stably. In actual use, a corresponding limiting lifting groove for the sliding of the extension rod 1210 can also be opened in the limiting sleeve rod 1211 to limit the lifting range of the limiting platform 1201.

[0069] like Figure 5 and Figure 6 As shown, the centering adjustment mechanism 15 includes a connecting frame 1501 connected to the lifting frame 1; a centering rod 1502 connected to the bottom of the connecting frame 1501; two groups of fork rods 1503 rotatably connected to the bottom end of the centering rod 1502 in the middle; two groups of positioning bars 1504 respectively installed on the top of the first template body 6 and the second template body 5, and the end of the fork rod 1503 away from the limiting mechanism 12 is rotatably connected to the positioning bar 1504; a slider 1505 rotatably connected to the end of the fork rod 1503 close to the limiting mechanism 12; and a slide groove 1506 arranged on the top of the positioning bar 1504 for the slider 1505 to slide;

[0070] Specifically, the connecting frame 1501 supports the centering rod 1502, and the centering rod 1502 can stabilize the rotation of the fork rod 1503. When the second template body 5 moves, it is transmitted through the two groups of fork rods 1503, that is, the fork rod 1503 rotates around the axis of the centering rod 1502, and the slider 1505 slides in the slide groove 1506. At the same time, the first template body 6 also moves synchronously. When the second template body 5 moves close to the side of the second circle plate 3, the first template body 6 moves close to the side of the first circle plate 2.

[0071] When the first template body 6 and the second template body 5 approach each other, the slider 1505 slides to the side close to the limiting mechanism 12. Restricted by the limiting platform 1201, the slider 1505 cannot continue to slide. At this time, the first template body 6 and the second template body 5 are adjusted into place, and the oil filling in the adjustment cavity A1103 is also completed.

[0072] A construction process of a concrete support formwork for sliding membrane construction comprises the following steps:

[0073] S1, the first formwork body 6 is installed on one side of the first enclosure plate 2, the side forms 7 are installed on both sides of the first formwork body 6, the second formwork body 5 is installed on one side of the second enclosure plate 3, the first enclosure plate 2 and the second enclosure plate 3 are fixed on the lifting frame 1 through the supporting mechanism 4, the tensioning mechanism 8 and the transmission mechanism 9 are installed in place, the limit mechanism 12 is installed in the debugging position on the lifting frame 1, the centering adjustment mechanism 15 is installed on the top of the first formwork body 6 and the second formwork body 5 and the debugging position, the distance adjustment mechanism 11 is installed on one side of the second enclosure plate 3, so that a cavity for concrete molding is formed between the first formwork body 6 and the second formwork body 5;

[0074] S2. Pre-embed steel pipes in the concrete structure as support rods for sliding membrane climbing and as lifting supports in supporting formwork forming;

[0075] S3, tying steel bars in the first formwork body 6 and the second formwork body 5, and pouring concrete into shape;
