Description

Technical Field

[0001] This application relates to the field of concrete pouring, and in particular to a construction formwork for wind power civil engineering projects. Background Technology

[0002] During the civil construction of wind power projects, concrete is used to cast-in-place components. Cast-in-place concrete requires unit slabs for support to maintain its shape before the concrete reaches a certain solidification strength. Once the concrete has reached its solidification strength, the unit slabs are removed.

[0003] For example, in a concrete building unit slab for wind power civil engineering with publication number CN218264911U, the casting frame is first slid vertically into the bridging block along the corresponding fixed frame. Then, the retaining strips are placed between two adjacent casting frames to prevent grout leakage between them. After the concrete pouring is completed, the fixed frame is moved upwards, and then the casting frame is dismantled.

[0004] Regarding the aforementioned technologies, since the dimensions of the fixed frame are fixed, the dimensions of the casting frame that slides into the fixed frame are also relatively fixed. Only by changing the thickness of the casting frame can the dimensions of the cast concrete components be changed within a small range. This makes it difficult to adapt to the casting of concrete components with large dimensional variations in different projects, and the unit slab as a whole cannot be effectively reused. Summary of the Invention

[0005] In order to enable the unit panels to be reused more effectively, this application provides a construction formwork for wind power civil engineering.

[0006] The technical solution for a construction formwork for wind power civil engineering provided in this application is as follows.

[0007] A construction formwork for wind power civil engineering includes four fixed-position corner pieces, a group of several fixed-position side pieces between two adjacent corner pieces, and a row of several unit plates sliding into the length direction of the corner pieces between two adjacent side pieces in the same group and between the side pieces and the corner pieces, as well as several pressing mechanisms corresponding to each row of unit plates for pressing.

[0008] By adopting the above technical solution, when the size of the concrete component to be poured changes, the spacing between the corner members can be changed, thereby changing the number of frame edge members between two adjacent corner members. This allows the final poured concrete component to adapt to the changes, better meeting the pouring needs of concrete components of different sizes in different projects. It also allows for better reuse of the unit panels. Furthermore, when pouring concrete components with a high pouring height, it is not necessary to move all the frame edge members and corner members vertically upwards; the unit panels can be disassembled simply by moving them horizontally, making it more convenient.

[0009] Optionally, the molding mechanism includes an upper rod detachably connected to the frame edge or frame corner piece, a push block provided on the upper rod, a molding cylinder provided on the push block, and a pressure block fixedly connected to the power rod of the molding cylinder and pressed tightly against the unit plate.

[0010] By adopting the above technical solution, after the unit plate is placed, the pressing cylinder can push the pressing block down to press against the unit plate, so that each unit plate is pressed tightly, thereby reducing the possibility of grout leakage from the unit plate.

[0011] Optionally, the upper rod is formed with a rod slope, and the push block is formed with a block slope that can abut against the rod slope to force the upper rod to move toward a unit plate that is further away.

[0012] By adopting the above technical solution, when the pressing cylinder pushes the pressing block against the unit plate, the reaction force of the pressing cylinder will force the pushing block to abut against the upper rod. Under the action of the block inclined surface and the rod inclined surface, the upper rod tends to move into the space of the concrete to be poured enclosed by all the unit plates. This makes it less likely for the upper part of the frame corner piece and frame edge piece to be bent due to the injected concrete slurry during the concrete pouring process.

[0013] Optionally, the pressed block has a waist groove, and a connector threaded to the unit plate passes through the waist groove. The connector is slidably connected to the waist groove along the length of the connected unit plate.

[0014] By adopting the above technical solution, the pressure block can maintain good stability when the pressure cylinder forces the pressure block to abut against the unit plate, and the position of the pressure block can be adjusted to a certain extent so that the block slope can better abut against the rod slope.

[0015] Optionally, the upper rod is slidably connected to the corner piece or the edge piece along the length of the corner piece. Both the corner piece and the edge piece have a row of several screw holes along the length of the corner piece, and the upper rod is threaded with a rod bolt connected to the screw hole.

[0016] By adopting the above technical solution, when pouring concrete components of different heights, each group of unit plates has a different height, and the extension length of the pressing cylinder is limited, the height of the upper rod needs to be adjusted, and the pressing cylinder does not need to be replaced.

[0017] Optionally, each of the frame corner pieces is fixedly connected to two side blocks. A connecting screw is placed between two adjacent side blocks of two adjacent frame corner pieces. The connecting screw is threadedly connected to a set of two pressing screw blocks. The adjacent sides of the two pressing screw blocks in the same set abut against the side blocks.

[0018] By adopting the above technical solution, the position of the two corner pieces remains stable, making it less likely for the distance between the upper parts of the two corner pieces to change during the concrete pouring process.

[0019] Optionally, the connecting screw is threadedly connected to a set of two push screw blocks, with the opposite sides of the two push screw blocks abutting against the edge block.

[0020] By adopting the above technical solution, when the unit panel needs to be removed after the concrete component has reached a certain solidification strength, the screw block is first rotated away from the edge block, and then the push screw block is rotated so that the push screw block abuts against the corresponding edge block, so that the corner pieces are moved away from each other, thereby driving the set of corner pieces and several rows of unit panels corresponding to each of the two corner pieces to move away synchronously, so that the unit panel can be disassembled.

[0021] Optionally, the connecting screw has an elongated opening along its length, and the upper surface of the side block has a lower opening for inserting the connecting screw. A rotation limiting block that can be inserted into the elongated opening is fixedly connected to the bottom surface of the lower opening.

[0022] By adopting the above technical solution, the connecting screw is less likely to rotate during the rotation of the pressing or pushing screw block.

[0023] Optionally, each of the connecting screws is threadedly connected to a group of several central screw blocks, each central screw block is coaxially rotatably connected to a rotating block close to a corresponding frame edge piece, the rotating block is threadedly connected to a rotating block screw, the rotating block screw is rotatably connected to a side abutment block, and the frame edge piece is provided with a piece that can abut against the side abutment block.

[0024] By adopting the above technical solution, the middle part of each frame component can also receive the force from the side abutment block, so that the frame component is less likely to bend during the pouring of large-volume concrete components.

[0025] Optionally, the frame edge is fixedly connected with a sleeve block, and two parts are slidably connected in each sleeve block. The opposite sides of the two parts are provided with part springs that force the two parts to approach each other, and the side abutment blocks can push the two parts away from each other.

[0026] By adopting the above technical solution, the side abutment block abuts against the two parts, so that when the frame edge part undergoes a small degree of bending deformation, the two clamping block springs will be compressed to reduce the pressure on the connecting screw, so that the connecting screw is not prone to bearing large radial pressure, so that when the frame edge part bends to a small degree as allowed, the connecting screw is not prone to bearing excessive pressure and deformation, so that the connecting screw is not easily damaged.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. Better adaptable to the casting needs of concrete components of different sizes in different projects, so as to better reuse the unit panels; 2. During the concrete pouring process, the upper part of the corner and edge members of the frame is less likely to bend due to the injected concrete grout. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a construction formwork for wind power civil engineering, referring to... Figure 1The system includes four vertical corner frames 1, each detachably connected at the bottom by screws and anchor rods. Between each pair of adjacent corner frames 1, there is a set of vertical side frames 2, each detachably connected at the bottom by screws and anchor rods. Several side frames 2 are evenly distributed along the line connecting the corresponding two corner frames 1. A row of unit plates 3 is installed between each pair of adjacent side frames 2 and between each corner frame 1 and a nearby side frame 2. The length of each unit plate 3 is aligned with the line connecting the corresponding two corner frames 1. Several unit plates 3 are arranged vertically in each group, and rollers can be installed at both ends of each unit plate 3 to facilitate smooth vertical movement within the grooves of the side frames 2 or corner frames 1. The space enclosed by the unit plates 3, side frames 2, and corner frames 1 is used for pouring concrete grout.

[0032] Reference Figure 2 Each corner piece 1 has two side blocks 41 fixedly connected near its center. The side blocks 41 of the same corner piece 1 have different heights and are located on two adjacent vertical sides. Each side block 41 has a lower opening 45 on its upper surface, which extends through the two opposite vertical sides of the side block 41. The same connecting screw 42 is placed in the lower opening 45 of two side blocks 41 of the same height on two adjacent corner pieces 1. The connecting screw 42 is horizontal and has a long opening 44 at its lower part along its length. A rotation limiting block 46 is fixedly connected in the lower opening 45 and can be inserted into and slid into the long opening 44, so that the position of the connecting screw 42 remains stable after it moves vertically downward into the lower opening 45.

[0033] Reference Figure 1 and Figure 2 Each connecting screw 42 is threadedly connected to a set of two pressing screw blocks 43 and a set of two pushing screw blocks 35. The adjacent sides of the two pressing screw blocks 43 in the same set abut against the opposite vertical sides of the two side blocks 41 for which the same connecting screw 42 is placed, making the middle of the two corner pieces 1 closer together, making the middle of the corner pieces 1 less prone to bending during the pouring of large volume concrete. The opposite sides of the two pushing screw blocks 35 in the same set abut against the adjacent vertical sides of the two side blocks 41 for which the same connecting screw 42 is placed, so that when the unit plate 3, the side block 2 and the corner piece 1 need to be completely removed after the concrete has solidified, the connection between the bottom of the corner piece 1 and the side block 2 and the corresponding anchor rod is first released, and then the two pushing screw blocks 35 are rotated to abut against the side block 41 to move the corresponding two corner pieces 1 away, so that the corresponding corner piece 1, side block 2 and unit plate 3 move away synchronously.

[0034] Reference Figure 2 and Figure 3Each connecting screw 42 is threadedly connected to several intermediate screw blocks 47. Each intermediate screw block 47 is coaxially rotatably connected to a rotating block 48. Each rotating block 48 is threadedly connected to a rotating block screw 32. The length direction of the rotating block screw 32 is consistent with the radial direction of the connecting screw 42. A side abutment block 49 is rotatably connected to the end of the rotating block screw 32 away from the rotating block 48. The side abutment block 49 is inserted into and slidably connected to the rotating block 48 along the length direction of the rotating block screw 32. Each frame edge piece 2 is fixedly connected to a sleeve block 33 near the middle of its vertical side. Inside the sleeve block 33, two pieces 31 are slidably connected in the vertical direction. Each of the two pieces 31 has a piece spring 34 fixedly connected to its opposite side. The piece spring 34 can push the two pieces 31 closer together. The side of the two pieces 31 that is close to each other away from the frame edge piece 2 and the upper and lower sides of the side abutment block 49 that are close to the piece 31 are all formed with slopes. This allows the slope of the side abutment block 49 to abut against the slope of the piece 31, so as to effectively support the middle of the frame edge piece 2. When the frame edge piece 2 undergoes a degree of deformation, the side abutment block 49 will not abut against the frame edge piece 2, so that the connecting screw 42 is not easily subjected to excessive radial pressure and is not easily damaged.

[0035] Reference Figure 1 and Figure 2 Several pressing mechanisms 4 are provided between the upper parts of two adjacent frame edge pieces 2 in the same group, and between the upper parts of frame edge pieces 2 and frame corner pieces 1, corresponding to each row of unit plates 3 for pressing. Each pressing mechanism 4 includes a pressing block 53 that abuts against the upper surface of the highest unit plate 3 in each group. Two waist grooves 56 are formed through the upper surface of the pressing block 53. The length direction of the waist grooves 56 is consistent with the length direction of the unit plate 3. The highest unit plate 3 in each group is threaded with two vertical connecting pieces 57. The two connecting pieces 57 are respectively inserted into the two waist grooves 56 to keep the position between the pressing block 53 and the unit plate 3 stable. A pressing cylinder 52 is fixedly connected to the upper surface of the pressing block 53. A push block 51 is fixedly connected to the upper end of the cylinder body of the pressing cylinder 52. A bevel 55 is formed on the upper part of the push block 51. A horizontal upper rod 5 is installed between the frame corner piece 1 and the adjacent frame edge piece 2 or between two adjacent frame edge pieces 2 in the same group. The upper rod 5 is formed with a rod slope 54 for the block slope 55 to abut against, so that when the power rod of the pressing cylinder 52 extends to press against the unit plate 3, the push block 51 will force the corresponding upper rod 5 to move towards the frame corner piece 1 or frame edge piece 2 on the opposite side, so that the upper part of the frame corner piece 1 and frame edge piece 2 is not easy to bend during the pouring of large volume concrete components.

[0036] Reference Figure 2Both the frame edge piece 2 and the frame corner piece 1 have a row of screw holes 58 on their vertical sides facing the upper rod 5. Several screw holes 58 are evenly distributed in each row along the vertical direction. The upper rod 5 is provided with a rod bolt 59 that can be threaded into a screw hole 58, so that the upper rod 5 can be height adjusted according to the height of a set of unit plates 3.

[0037] The implementation principle of a construction formwork for wind power civil engineering in this application embodiment is as follows: Different numbers of frame edge pieces 2 can be placed between two adjacent corner pieces 1, allowing for significant adjustment of the space dimensions for concrete pouring enclosed by the corner pieces 1, frame edge pieces 2, and unit plates 3. This adapts to the pouring of concrete components with large size differences in various projects. Furthermore, during the pouring of large-volume concrete components, the upper and middle parts of the corner pieces 1 and frame edge pieces 2 receive good support, preventing significant bending deformation during concrete pouring and ensuring smooth concrete pouring.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
