[0002] During the construction of cast-in-place reinforced concrete floor slabs, according to the construction deployment and resource allocation, construction is carried out in zones and blocks. Since the slab reinforcement should not be disconnected, perforated formwork is usually used to intercept concrete at the required positions and limit the radial direction of the slab reinforcement to ensure the quality of structural construction. Usually, the formwork is made by cutting and processing wooden boards according to the length required at the construction site. However, once the formwork is made, its length is fixed and it cannot be applied to other areas with different required lengths, resulting in low applicability. Content of the Utility Model

[0005] At least two formworks are spliced in sequence along the first direction so that the length of the formwork assembly in the first direction is adapted to the length of the construction joint. Here, the first direction is the length direction of the construction joint. The formwork is suitable for intercepting concrete and abuts against the outer peripheral wall of the slab reinforcement to form a limit on the radial direction of the slab reinforcement;

[0006] Connecting pieces are arranged at the splicing positions of adjacent two formworks to make the adjacent two formworks form a detachable connection.

[0007] Beneficial effect: By splicing multiple formworks according to the length of the construction joint, after the formwork is made once, it can be applied to construction joints with different lengths, thereby improving the applicability and turnover rate of the formwork.

[0008] In an optional embodiment, a groove is formed by local depression of the first end surface of the formwork along the first direction, and a convex block is formed by local protrusion of the second end surface. The convex block is suitable for being embedded into the adjacent groove to make the adjacent two formworks form a splice.

[0009] Beneficial effect: By the form of embedding connection between the convex block and the groove, it is beneficial to improve the splicing stability of adjacent two formworks.

[0011] Beneficial effects: Two adjacent templates form a detachable connection through the connecting piece, which is beneficial to improving the stability of the template assembly during use and the convenience during disassembly, and is beneficial to the turnover use of the template assembly.

[0012] In an alternative embodiment, the first connection hole and the second connection hole include threaded holes, and the connecting piece includes a bolt.

[0035] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] The following Figures 1 to 6 is combined to describe the embodiments of the present utility model.

[0037] According to an embodiment of the present utility model, a formwork assembly is provided, which is arranged at a construction joint to intercept concrete and limit the radial direction of the slab reinforcement 2. The formwork assembly includes:

[0038] At least two formworks 1 are spliced in sequence along a first direction so that the length of the formwork assembly in the first direction is adapted to the length of the construction joint. Wherein, the first direction is the length direction of the construction joint, and the formwork 1 is adapted to intercept concrete and abut against the outer peripheral wall of the slab reinforcement 2 to form a limit to the radial direction of the slab reinforcement 2;

[0039] A connecting member 3 is arranged at the splicing position of two adjacent formworks 1 to make the two adjacent formworks 1 form a detachable connection.

[0040] The formwork assembly provided in this embodiment improves the applicable range and turnover rate of the formwork 1 by splicing multiple formworks 1 according to the length of the construction joint, and after the formwork 1 is manufactured once, it can be applied to construction joints of different lengths.

[0041] Specifically, taking the construction of a cast-in-place floor slab as an example, when partitioned and segmented construction is required, construction joints will be formed at the required positions. The slab surface reinforcement bars 2 span across the construction joints and are not easily disconnected at the construction joints. Therefore, a formwork assembly is provided at the construction joints to intercept the concrete and limit the slab surface reinforcement bars 2 to ensure that the slab surface reinforcement bars 2 do not undergo large displacements during the concrete pouring process, thereby ensuring the construction quality of the cast-in-place floor slab.

[0042] The main plane of the formwork 1 is set at an angle to the horizontal direction, and the spacing between the upper and lower end faces of the formwork 1 in the height direction is adapted to the height of the construction joint to facilitate intercepting the concrete. The length direction of the formwork 1 is parallel to the first direction. According to the length of the construction joint, an appropriate number of formworks 1 are selected, and multiple formworks 1 are spliced in sequence along the first direction. By changing the number of formworks 1, the formwork assembly can be made applicable to construction joints of different lengths. Compared with the related art where wooden boards are cut and made according to the length of the construction joint and cannot be applicable to construction joints of different lengths, it has higher applicability and turnover rate. And compared with the use of quick-setting closing nets at the construction joints in the related art, the formwork assembly is not easily deformed and cracked during use.

[0043] The number of the slab surface reinforcement bars 2 includes multiple ones, and the axial directions of the multiple slab surface reinforcement bars 2 are set at an angle to the length direction of the construction joint. The formwork 1 limits the radial direction of the slab surface reinforcement bars 2 spanning across the construction joint to reduce or avoid the radial displacement of the slab surface reinforcement bars 2 during the pouring of the floor slab concrete, thereby improving the construction quality of the cast-in-place floor slab. Adjacent two formworks 1 are detachably connected through a connecting member 3 to facilitate the assembly and disassembly of the formwork assembly, thereby ensuring the stability of the formwork assembly during use and the portability during turnover and transportation.

[0044] In some embodiments, as shown in Figures 1 to 6 a local area of the first end face of the formwork 1 along the first direction is recessed to form a groove 11, and a local area of the second end face is protruded to form a convex block 12. The convex block 12 is adapted to be embedded in the adjacent groove 11 to enable splicing of adjacent two formworks 1.

[0045] For the formwork assembly provided in this embodiment, in the form of embedding and connecting the convex block 12 and the groove 11, it is beneficial to improve the splicing stability of adjacent two formworks 1.

[0046] Specifically, at least one groove 11 is formed on the first end surface, and an opening is formed on the first end surface, and at least one convex block 12 is formed on the second end surface. The convex block 12 is arranged corresponding to the groove 11, and the size of the convex block 12 is adapted to the size of the groove 11, so that when assembling the template assembly, the convex block 12 of one template 1 is inserted into the groove 11 through the opening on the first end surface of another adjacent template 1, which is conducive to improving the splicing stability between the two adjacent templates 1. As a feasible implementation form, combined with Figures 1 to 3 As shown, the groove 11 passes through the template 1 along a direction parallel to the main plane of the template 1 and perpendicular to the first direction, so that the protrusion 12 is suitable for sliding into the groove 11; as an additional embodiment, combined with Figures 4 to 6 As shown, the groove 11 runs through the template 1 along a direction perpendicular to the main plane of the template 1, so that the protrusion 12 can be slidably embedded in the groove 11, which is beneficial to improving the convenience and operability of assembly and improving the construction efficiency.

[0047] In some embodiments, in combination Figures 1 to 6 As shown, a first connecting hole 111 is provided on the side surface of the template 1 close to its first end face corresponding to the groove 11, and the first connecting hole 111 is communicated with the inside of the groove 11; a second connecting hole 121 is provided on the protrusion 12 corresponding to the first connecting hole 111, and the connecting member 3 is passed through the first connecting hole 111 and the second connecting hole 121, so that two adjacent templates 1 form a detachable connection.

[0048] In the template assembly provided in this embodiment, two adjacent templates 1 are detachably connected via a connector 3, which is beneficial to improving the stability of the template assembly during use and the convenience during disassembly, and is beneficial to the turnover use of the template assembly.

[0049] Preferably, the inner diameter of the first connection hole 111 matches the inner diameter of the second connection hole 121. After the two adjacent templates 1 are spliced, the axis of the first connection hole 111 coincides with the axis of the second connection hole 121, so that the connector 3 can be detachably inserted into the first connection hole 111 and the second connection hole 121, thereby forming a detachable connection between the first connection hole 111 and the second connection hole 121. When the template assembly is used, two adjacent templates 1 are connected by the connector 3, which is beneficial to improving the stability of the template assembly. When the template assembly needs to be dismantled or rotated, the connector 3 is taken out from the first connection hole 111 and the second connection hole 121, so that the template assembly can be conveniently split into multiple single templates 1, which is beneficial to turnover and transportation.

[0050] In some embodiments, in combination Figures 1 to 6 As shown, the first connecting hole 111 and the second connecting hole 121 include threaded holes, and the connecting member 3 includes bolts.

[0051] Specifically, the first connection hole 111 and the second connection hole 121 include threaded holes and through holes. The connecting member 3 includes bolts and ball lock pins. The first connection hole 111 and the second connection hole 121 can form a detachable connection in the form of bolt connection or in the form of pin connection.

[0052] In some embodiments, as shown in Figures 1 to 6 the main plane of the formwork 1 is parallel to the direction of gravity. At least one end face partial area of the formwork 1 in the second direction is recessed to form a limiting groove 13. A partial area of the slab reinforcement 2 is inserted into the limiting groove 13 so that the formwork 1 limits the radial direction of the slab reinforcement 2.

[0053] For the formwork assembly provided in this embodiment, by inserting a partial area of the slab reinforcement 2 into the limiting groove 13, it is convenient for the inner wall of the limiting groove 13 to abut against the outer peripheral wall of the slab reinforcement 2, thereby forming a limit on the radial direction of the slab reinforcement 2, which is beneficial to ensuring the stability of the slab reinforcement 2 during the floor slab pouring process.

[0054] Specifically, the main plane of the formwork 1 is parallel to the first direction. Preferably, the main plane of the formwork 1 is parallel to the direction of gravity to facilitate intercepting the concrete at the construction joint. The second direction is a direction parallel to the main plane of the formwork 1 and perpendicular to the first direction. Along the axial direction of the slab reinforcement 2, the limiting groove 13 penetrates through the formwork 1 to facilitate a partial area of the slab reinforcement 2 to fall into the limiting groove 13.

[0055] In some embodiments, as shown in Figures 1 to 6 the projection shape of the limiting groove 13 along the axial direction of the slab reinforcement 2 includes a rectangle.

[0056] Specifically, along the axial direction of the slab reinforcement 2, the projection shape of the limiting groove 13 includes a rectangle, a semi-waist shape, and a semi-circular shape. Preferably, the opening size of the limiting groove 13 on the end face of the formwork 1 in the second direction is the same as the outer diameter size of the slab reinforcement 2 to be suitable for the side wall of the limiting groove 13 to abut against the outer peripheral wall of the slab reinforcement 2, thereby forming a limit on the radial direction of the slab reinforcement 2.

[0057] In some embodiments, as shown in Figures 1 to 6 the number of the limiting grooves 13 includes a plurality, and the plurality of limiting grooves 13 are equally spaced along the first direction.

[0058] Specifically, the slab surface steel bars 2 include multiple ones, and the multiple slab surface steel bars 2 are parallel and spaced along the first direction. Preferably, the spacing between adjacent two slab surface steel bars 2 is the same, and the position of the limit grooves 13 on the formwork 1 is adapted to the position of the slab surface steel bars 2. Further, along the first direction, the interval spacing between adjacent two limit grooves 13 is 20 mm to 80 mm, the opening length of the limit groove 13 is 10 mm to 40 mm, and the depth of the limit groove 13 is 10 mm to 40 mm. As a feasible implementation form, the interval spacing between adjacent two limit grooves 13 is 40 mm, the opening length of the limit groove 13 is 20 mm, and the depth of the limit groove 13 is 20 mm.

[0059] In some embodiments, as shown in Figures 1 to 6 , along the first direction, the length of the formwork 1 is L, where 1 m ≤ L ≤ 5 m.

[0060] For the formwork assembly provided in this embodiment, by manufacturing formworks 1 with various length specifications, it is convenient to select a longer formwork 1 for splicing when the length of the construction joint is longer, and select a shorter formwork 1 for splicing when the length of the construction joint is shorter, which is beneficial to improving the splicing efficiency and operability of the formwork assembly.

[0061] Specifically, by setting formworks 1 with different lengths, for example, the lengths of the formworks 1 are selected as 1 m, 3 m, and 5 m. When the length of the construction joint is longer, a longer formwork 1 is selected, so that it is possible to meet the required length with a smaller number of formworks 1, which is beneficial to improving the construction efficiency; when the length of the construction joint is shorter, a shorter formwork 1 is selected to facilitate the convenience and accuracy in assembling the formwork assembly. Of course, formworks 1 with different lengths can be selected for combined splicing in the same formwork assembly.

[0062] In some embodiments, as shown in Figures 1 to 6 , the thickness of the formwork 1 is H, where 15 mm ≤ H ≤ 20 mm.

[0063] For the formwork assembly provided in this embodiment, by limiting the thickness range of the formwork 1, it is possible to avoid the formwork 1 being too thin resulting in insufficient self-strength and being easily damaged, and avoid the formwork 1 being too thick which is not convenient for construction and transportation.

[0064] In some embodiments, as shown in Figures 1 to 6 , the formwork 1 includes a plastic plate.

[0065] For the formwork assembly provided in this embodiment, compared with the formwork 1 made of wood in the related art, making it of plastic material can improve the structural strength of the formwork 1, and it is not easily damaged and deformed, which is beneficial to improving the turnover rate.

[0066] Specifically, the formwork 1 includes plastic plates, steel plates, and composite material plates. Preferably, the formwork 1 is made of plastic plates. Compared with wooden boards, plastic plates are easy to process, have high structural strength, are not easily damaged or deformed, which is beneficial to improving the concrete forming quality and the turnover rate of the formwork components, beneficial to cost reduction, and plastic plates can withstand rain erosion and exposure to higher temperatures; in addition, plastic plates usually have a smooth surface, which is beneficial to reducing the time for subsequent concrete roughening treatment; for the same volume, the weight of plastic plates is lighter than that of wooden boards, which is beneficial to construction operations and turnover transportation; compared with wooden boards sourced from forest trees, plastic plates are sourced from recyclable plastics, which is beneficial to meeting the requirements of green environmental protection.

[0067] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
