Description

Technical Field

[0001] The utility model relates to the technical field of building formwork, and particularly relates to an efficient assembled ribbed floor slab forming structure. Background Art

[0002] A Miller floor formwork is a formwork used in building engineering, mainly for the construction of cast-in-place concrete two-way ribbed floor slabs (floor slabs), and is suitable for the construction of large-span and large-load spaces, such as underground garages, large shopping malls, multi-story factories, teaching buildings, civil air defense projects, etc.

[0003] In the prior art, generally, a full hall scaffold is pre-erected, a wooden board is laid on the scaffold, and the formwork is then laid flat on the wooden board. This method requires a relatively dense laying of the scaffold, and the positioning accuracy between the formworks is relatively low, which is time-consuming and laborious. In addition, there is another method of pre-erecting a full hall scaffold, installing a jack on the top of the scaffold, and through holes are provided on both the flange edges of the jack and the formwork, and bolts are passed through the through holes and tightened with nuts. This method has the following problems:

[0004] First, during the assembly process of the formwork, someone needs to twist the bolts above and below the formwork at the same time, which is very inconvenient. The workload is increased during both the formwork assembly and demoulding. And before passing the bolts, the holes of the formwork and the jack need to be aligned. When the holes are misaligned, the position of the scaffold needs to be corrected. However, the scaffold is pre-erected, and the columns are connected by crossbars and have been connected into a whole, so the workload of modifying the position is huge.

[0005] Second, due to the existence of the through holes, during grouting, the concrete slurry is likely to flow down from the gap between the bolts and the through holes.

[0006] Third, due to the use of bolt connection, the upper surface of the bolt and the formwork cannot be smoothly transitioned. When demoulding, the lower surface of the ribbed floor slab is uneven and requires secondary treatment, increasing the workload.

[0007] Fourth, the surface of the formwork in contact with the main beam still has through holes, which is easy to leak slurry, and the corresponding position of the main beam is uneven after demoulding. Content of the Utility Model

[0008] The problem solved by the utility model is that in the actual construction process of the prior art, there are problems of huge workload, uneven surface after demoulding, and easy slurry leakage. Now the utility model provides an efficient assembled ribbed floor slab forming structure.

[0009] The utility model is realized through the following technical solutions. An efficient assembled ribbed floor slab forming structure includes a plurality of prefabricated formworks and a support assembly erected on site;

[0010] The formwork shell includes a top surface of the formwork shell. A formwork shell side extending downward is connected to the perimeter of the top surface of the formwork shell. A cavity is formed inside the top surface of the formwork shell and the enclosing formwork shell side. The lower edge of the formwork shell side continues to horizontally extend outward to form a flange edge. The outer contour of the circle of flange edges is rectangular. The vertical end surface of the outer edge of the flange edge forms a fitting surface for the formwork shells to abut against each other. The formwork shell is divided into corner formwork shells, side formwork shells, and central formwork shells according to the installation position. Connection holes are provided on two adjacent fitting surfaces of the corner formwork shell. Connection holes are provided on three adjacent fitting surfaces of the side formwork shell. Connection holes are provided on all four fitting surfaces of the central formwork shell. The number of connection holes on a single fitting surface is one or more. The connection holes are horizontally arranged and penetrate from the cavity to the fitting surface and are perpendicular to the fitting surface.

[0011] The support assembly includes a top bracket, a vertical rod, and a cross bar. The top bracket includes a top plate and a telescopic rod. The top plate is horizontally arranged. A telescopic rod is connected to the lower surface of the top plate. The telescopic rod is perpendicular to the lower surface of the top plate. The telescopic rod is installed at the top of the vertical rod. A circular connecting disk that can be buckled is provided on the vertical rod. One or more cross bars are connected between each pair of adjacent two connecting rods. And each vertical rod and the closest main beam scaffold are connected by a cross bar.

[0012] The fitting surfaces in several formwork shells are abutted against each other in pairs to form a rectangular formwork shell array. The lower bottom surfaces of all formwork shells are coplanar. The positions of the connection holes on the fitting surfaces of adjacent two formwork shells are the same. Adjacent two formwork shells are tightly connected by fasteners passing through the connection holes. The outermost edge of the formwork shell array is erected on the existing main beam formwork. A top bracket is provided below the common corner position of each group of adjacent four formwork shells. The upper surface of the top plate of each top bracket abuts against the lower bottom surfaces of the four formwork shells.

[0013] Further, one or more positioning grooves are provided on the lower bottom surface of the flange edge. The positioning grooves are close to the corner positions of the flange edge. The positioning grooves are perpendicular to the lower bottom surface of the flange edge. One or more positioning protrusions are provided on the upper surface of the top plate. The positioning protrusions are perpendicular to the upper surface of the top plate. During installation, the positioning protrusions provided on the top plate are inserted into the positioning grooves in one or more formwork shells.

[0014] Further, chamfers for guiding are provided on the positioning protrusions and the positioning grooves.

[0015] Another aspect of the utility model in this case provides an efficient prefabricated ribbed floor forming construction method, including:

[0016] Preparation before construction: Complete the prefabrication of formwork shells, top brackets, and fasteners according to construction requirements. Prepare the corresponding support assembly. According to the drawings, erect the side formwork of the main beam to determine the installation height of the bottom surface of the ribbed floor.

[0017] Construction process: Start from a corner of the surrounding main beams and sequentially erect the formwork and the adjustable support along one side of the main beam. Subsequently, sequentially erect the remaining formwork and adjustable support along the side of the already erected formwork or the main beam until the formwork covers the area to be laid. The detailed steps are as follows:

[0018] Install the corner formwork: Prop up a vertical pole with an adjustable support. Orient the two mating surfaces without connection holes on the corner formwork towards the side form of the main beam. The three corners under the corresponding two mating surfaces are respectively placed on the upper surfaces of the two side forms of the main beam, and the remaining one corner of the corner formwork is placed on the adjustable support. The upper surface of the top plate abuts against the lower surface of the corner formwork;

[0019] Install the side formwork: Prop up a new vertical pole with an adjustable support. Orient one mating surface without connection holes on the side formwork towards the side form of the main beam. The two corners under the corresponding one mating surface are placed on the upper surface of the side form of the main beam, the third corner is placed on the existing adjustable support, and the fourth corner is placed on the newly propped up adjustable support. The upper surface of the top plate abuts against the lower surface of the corner formwork. Press the mating surfaces of the newly installed formwork and the already installed formwork tightly together, and tightly connect the two formworks through fasteners penetrating the connection holes;

[0020] Install the center formwork: Prop up a new vertical pole with an adjustable support. Place the three corners of the center formwork on the existing adjustable support, and the fourth corner on the newly propped up adjustable support. The upper surface of the top plate abuts against the lower surface of the corner formwork. Press the mating surfaces of the newly installed formwork and the already installed formwork tightly together, and tightly connect the two formworks through fasteners penetrating the connection holes;

[0021] In the above process, starting from the second formwork, when installing each formwork, press the mating surfaces of the newly installed formwork and the already installed formwork tightly together, and tightly connect the two formworks through fasteners penetrating the connection holes;

[0022] In the above process, for each newly propped up vertical pole, the newly propped up vertical pole is connected to the surrounding vertical poles or the main beam scaffolding through crossbars. The number and spacing of the crossbars at least meet the requirements of the design specifications.

[0023] Furthermore, one or more positioning grooves are provided on the lower bottom surface of the flange edge. The positioning grooves are located near the corners of the flange edge and are perpendicular to the lower bottom surface of the flange edge; one or more positioning protrusions are provided on the upper surface of the top plate. The positioning protrusions are perpendicular to the upper surface of the top plate. During installation, the positioning protrusions on the adjustable support are inserted into the positioning grooves of at least one of each group of adjacent four formworks.

[0024] Furthermore, the flange edge and the supporting plate of the adjustable support are detachably and fixedly connected.

[0025] Furthermore, the workers installing the formwork are assisted by a mobile platform during installation.

[0026] Furthermore, during installation, the workers on the mobile platform and the workers on the ground work simultaneously.

[0027] Furthermore, according to the requirements of the drawings, the formwork is prefabricated with standard formwork and non-standard formwork. The sizes of the standard formwork are all the same, and the differences between the non-standard formwork and the standard formwork lie in their lengths and widths.

[0028] Furthermore, the vertical poles under the standard formwork are connected by socket connections, and the cross bars between the vertical poles under the non-standard formwork are connected by socket connections or cross fasteners.

[0029] Furthermore, diagonal bracing rods are also arranged between the vertical poles.

[0030] Furthermore, reinforce the steel bars, pour the concrete, and cure on the already erected high-efficiency assembled ribbed floor forming structure. After curing and forming, remove the fasteners, lower the height of the adjustable jack, and remove the formwork and the entire support assembly for ready to be reused after turnover.

[0031] The beneficial effects of the present utility model are as follows:

[0032] 1. The high-efficiency assembled ribbed floor support structure of the present utility model can support the common corners of four formworks. Moreover, there are no upper and lower perforations on the flange edges of the formworks, which avoids leakage of mortar and also avoids pits left on the lower surface of the floor after demoulding during bolt connection, eliminating the need for additional filling work. The columns are connected by cross bars, which improves the stability of the vertical poles, and the socket connection is very convenient for installation. The corners of the formworks are placed on the adjustable jacks, and no additional measures are required for connection, reducing the workload.

[0033] 2. The formwork and the adjustable jack of the present utility model are respectively provided with positioning grooves and positioning protrusions, which can realize the rapid positioning of the formwork, avoid the formwork from moving horizontally, and without the need for bolt connection, reducing the installation workload. There are no vertical openings on the flange edges of the formworks, preventing mortar leakage, and the ribbed floor is smoother and more beautiful after demoulding.

[0034] 3. The present utility model is divided into corner formwork, side formwork, and center formwork according to the installation position. The connection holes on the outer fitting surfaces of the formwork components are cancelled, reducing the number of holes opened on the formworks, avoiding mortar leakage, and improving the flatness of the main beam after demoulding.

[0035] 4. During the construction of the utility model, there is no need to pre-erect a full-floor scaffolding. It is only necessary to erect the main beam side formwork in advance according to the drawings, and to successively erect the formwork and the top support starting from one corner of the main beams around it along one side of the main beam. Subsequently, the remaining formwork and the top support are successively erected along the erected formwork or the edge of the main beam until the formwork covers all the places where it needs to be laid. In this process, before installing each formwork, a vertical pole with a top support is pre-erected, and then the formwork is placed on the main beam side formwork or the erected top support. Before or when installing the formwork, after the formwork is installed, the vertical pole can be adjusted to ensure that one corner of the formwork just covers one quarter of the top plate. The subsequent vertical poles are connected to the already erected vertical poles or the main beam scaffolding through cross bars. The cross bars generally adopt a disc-type connection, which has a fast installation speed and standard size. The subsequent vertical poles do not need to be adjusted to ensure high precision. The support assembly and the formwork of this solution are erected simultaneously, the erection efficiency is high, and no additional connection structure is required between the top support and the formwork, so the workload is small.

[0036] 5. The workers who install the formwork in the utility model use the mobile platform to assist in the installation, such as setting up the formwork, installing the fasteners between the formworks, and installing the upper crossbars. The workers on the ground are responsible for setting up the vertical poles and the bottom crossbars. During the installation, the workers on the mobile platform and the workers on the ground work at the same time. After installing a formwork, the mobile platform directly moves people to the appropriate position to avoid interference with the already set up scaffolding. The combination is reasonable and the work efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0061] Embodiment 1, as Figures 1-3As shown in the figure, an efficient prefabricated ribbed floor forming structure includes a number of prefabricated formwork 10 and a support assembly 20 erected on site;

[0062] As Figure 2 shown, the formwork 10 includes a formwork top surface 11, and a formwork side surface 12 extending downward is connected to the periphery of the formwork top surface 11. A cavity 13 is formed inside the formwork top surface 11 and the enclosing formwork side surface 12. The lower edge of the formwork side surface 12 continues to horizontally extend outward to form a flange 14. The outer contour of the circle of flanges 14 is rectangular, and the vertical end surface of the outer edge of the flange 14 forms a joint surface 15 for the formwork 10 to abut against each other; As Figure 4 shown, the formwork 10 is divided into corner formwork 100, side formwork 200, and center formwork 300 according to the installation position; connection holes 16 are provided on two adjacent joint surfaces 15 of the corner formwork 100; connection holes 16 are provided on three adjacent joint surfaces 15 of the side formwork 200; connection holes 16 are provided on all four joint surfaces 15 of the center formwork 300, and the number of connection holes 16 on a single joint surface 15 is one or more. In this embodiment, three are provided. The connection holes 16 are horizontally arranged and penetrate from the cavity 13 to the joint surface 15 and are perpendicular to the joint surface 15;

[0063] As Figure 3 shown, the support assembly 20 includes a jack 21, a vertical rod 23, and a cross bar 25. The jack 21 includes a top plate 2101 and a telescopic rod 22. The top plate 2101 is horizontally arranged, and the shape of the top plate 2101 can be any shape. Generally, it is square or circular for easy production. The telescopic rod 22 is connected to the lower surface of the top plate 2101. The telescopic rod 22 is perpendicular to the lower surface of the top plate 2101. The telescopic rod 22 is installed on the top of the vertical rod 23. A circular connecting plate 24 that can be buckled is provided on the vertical rod 23. One or more cross bars 25 are connected between each pair of adjacent two connecting rods, and each vertical rod 23 and the closest main beam scaffold 33 are connected by the cross bar 25 to ensure the stability of the vertical rod 23;

[0064] As shown in Figure 1, there are nine formwork shells 10 arranged in a 3×3 array. The lower bottom surfaces of all the formwork shells 10 are coplanar. The formwork shells 10 are connected to each other through the through holes 16 of the fasteners. There are four positions where four formwork shells 10 share a corner among the nine formwork shells 10. Therefore, four adjustable supports 21 are provided. The support plates of the adjustable supports 21 abut against the corner positions of the four formwork shells 10. The outermost corners of the formwork shells 10 can be erected on the side formwork of the main beam. Therefore, adjustable supports 21 are not provided at positions where four formwork shells 10 do not share a corner. The height is adjusted by the telescopic rod 22 below the adjustable support 21. The telescopic rod 22 is connected to the vertical rod 23 below. A plurality of cross bars 25 are buckled between each pair of adjacent connecting rods to improve the stability of the vertical rod 23. And through the socket connection, the installation of the cross bar 25 is very convenient and fast. In practical applications, the number of formwork shells 10 and adjustable supports 21 is more. The 3×3 in this solution is only for demonstration purposes. In this solution, the high-efficiency assembled ribbed floor support structure can support the corners where four formwork shells 10 meet. Moreover, there are no upper and lower through holes on the flange edge 14 of the formwork shell 10, which avoids slurry leakage and also avoids pits left on the lower surface of the floor after demoulding during bolt connection, eliminating the need for additional filling work. The vertical columns are connected by the cross bars 25 to improve the stability of the vertical rod 23, and the socket connection makes the installation very convenient. The corners of the formwork shell 10 are erected on the adjustable support 21, and no additional measures are required for connection, reducing the workload.

[0065] Embodiment 2, as Figures 4-6 shown, the difference from Embodiment 1 is that four positioning grooves 17 are provided on the lower bottom surface of the flange edge 14. The positioning grooves 17 are close to the corner positions of the flange edge 14, and the positioning grooves 17 are perpendicular to the lower bottom surface of the flange edge 14; four positioning protrusions 2102 are provided on the upper surface of the top plate 2101. The positioning protrusions 2102 are perpendicular to the upper surface of the top plate 2101. During installation, the four positioning protrusions 2102 provided on the top plate 2101 are inserted into the positioning grooves 17 in the four formwork shells 10. In this solution, the positioning grooves 17 and the positioning protrusions 2102 can realize the rapid positioning of the formwork shells 10, avoid the formwork shells 10 from moving horizontally, and there is no need for bolt connection, reducing the installation workload.

[0066] Embodiment 3, as Figures 7-8As shown in the figure, the difference from the fourth embodiment is that four positioning grooves 17 are provided on the lower bottom surface of the flange edge 14, and a positioning bump 2102 is provided on the upper surface of the top plate 2101. During installation, the positioning bump 2102 is inserted into the positioning groove 17 of any one of the adjacent four formwork shells 10. Since the adjacent formwork shells 10 are fastened and connected to each other through the fastening holes 16 by fasteners and are connected into a whole, therefore, positioning one formwork shell 10 by one positioning bump 2102 will also limit the horizontal movement of other formwork shells 10. Compared with the second embodiment, the number of positioning bumps 2102 and positioning grooves 17 is reduced, and the installation is more convenient.

[0067] Another aspect of the present invention provides an efficient prefabricated ribbed floor forming construction method.

[0068] Embodiment 5, as Figures 10-14 shown, is an efficient prefabricated ribbed floor forming construction method, including:

[0069] Preparation before construction: Complete the prefabrication of the formwork shell 10, the top support 21 and the fasteners according to the construction requirements, prepare the corresponding support assembly 20, and set up the side formwork 32 of the main beam according to the drawing. Determine the installation height of the bottom surface of the ribbed floor according to the height of the side formwork 32 of the main beam;

[0070] Construction process: Start from a corner of the main beam around and sequentially set up the formwork shell 10 and the top support 21 along one side of the main beam. Subsequently, sequentially set up the remaining formwork shell 10 and the top support 21 along the side of the already set up formwork shell 10 or the main beam until the formwork shell 10 covers the place to be laid. As Figure 10 shown, start setting up from a corner of the main beam. Subsequently, as Figure 12 shown, set up two side formwork shells 200 on the right. After setting up six formwork shells 10, as Figure 13 shown, set up the second row and the third row along the already set up formwork shell 10. Finally, as Figure 15 shown, set up all the formwork shells 10. The detailed steps are as follows:

[0071] Install the corner formwork shell 100: Prop up a vertical rod 23 with a top support 21, and orient the two mating surfaces 15 without the connection hole 16 on the corner formwork shell 100 towards the side formwork 32 of the main beam. The three corners under the corresponding two mating surfaces 15 are respectively placed on the upper surface of the two side formwork 32 of the main beam, and the remaining one corner of the corner formwork shell 100 is placed on the top support 21. The upper surface of the top plate 2101 abuts against the lower surface of the corner formwork shell 100;

[0072] Install the side formwork shell 200: Erect a new vertical pole 23 with a jack 21. Orient one mating surface 15 of the side formwork shell 200 without a connection hole 16 towards the main beam side form 32. Rest the two corners under the corresponding mating surface 15 on the upper surface of the main beam side form 32, the third corner on the existing jack 21, and the fourth corner on the newly erected jack 21. The upper surface of the top plate 2101 abuts against the lower surface of the corner formwork shell 100. Press the mating surfaces 15 of the newly installed formwork shell 10 and the already installed formwork shell 10 tightly together, and use fasteners to pass through the connection holes 16 to tightly connect the two formwork shells 10;

[0073] Install the center formwork shell 300: Erect a new vertical pole 23 with a jack 21. Rest three corners of the center formwork shell 300 on the existing jacks 21, and the fourth corner on the newly erected jack 21. The upper surface of the top plate 2101 abuts against the lower surface of the corner formwork shell 100. Press the mating surfaces 15 of the newly installed formwork shell 10 and the already installed formwork shell 10 tightly together, and use fasteners to pass through the connection holes 16 to tightly connect the two formwork shells 10;

[0074] In the above process, starting from the second formwork shell 10, each time a formwork shell 10 is installed, press the mating surfaces 15 of the newly installed formwork shell 10 and the already installed formwork shell 10 tightly together, and use fasteners to pass through the connection holes 16 to tightly connect the two formwork shells 10;

[0075] In the above process, each time a new vertical pole 23 is erected, the newly erected vertical pole 23 is connected to the surrounding vertical poles 23 or the main beam scaffold 33 through crossbars 25. The number and spacing of the crossbars 25 at least meet the requirements of the design specifications.

[0076] In practical applications, the workers installing the formwork shell 10 are assisted by a mobile platform 41 during installation, such as erecting the formwork shell 10, installing the fasteners between the formwork shells 10, and installing the upper crossbars 25. The workers on the ground are responsible for erecting the vertical poles 23 and the bottom crossbars 25. During installation, the workers on the mobile platform 41 and the workers on the ground work simultaneously. After installing a formwork shell 10, the mobile platform 41 directly carries people and moves to a suitable position to avoid interference with the already erected scaffold. Part of the scaffold of the main beam scaffold 33 can be removed as needed to allow the mobile platform 41 to enter and exit, and it can be restored before pouring.

[0077] In this solution, there is no need to pre-erect a full hall scaffold. Only the side formwork 32 of the main beam needs to be erected in advance according to requirements, and the formwork shells 10 and the adjustable supports 21 are erected in sequence along one side of the main beam starting from a corner of the main beam on all sides. Subsequently, the remaining formwork shells 10 and adjustable supports 21 are erected in sequence along the erected formwork shells 10 or the sides of the main beam until the formwork shells 10 cover all the places to be laid. During this process, before installing each formwork shell 10, a vertical pole 23 with an adjustable support 21 is erected in advance, and then the formwork shell 10 is placed on the side formwork 32 of the main beam or the erected adjustable support 21. The position of the vertical pole 23 can be adjusted before or during the installation of the formwork shell 10. After the installation of this formwork shell 10 is completed, ensure that one corner of the formwork shell 10 just covers one-fourth of the top plate 2101. The subsequent vertical poles 23 are connected to the already erected vertical poles 23 or the main beam scaffold 33 through cross bars 25. The cross bars 25 generally adopt socket connections, which have a fast installation speed and standard sizes. The subsequent vertical poles 23 do not need to be adjusted to ensure high precision. The support mechanism of this solution is gradually erected along with the erection of the formwork shells 10, with high erection efficiency, and there is no need for an additional connection structure between the adjustable supports 21 and the formwork shells 10, resulting in less workload. The flange edge 14 of the formwork shell 10 is not provided with upper and lower through holes, which avoids mortar leakage and also avoids pits left on the lower surface of the floor slab after demoulding during bolt connection, eliminating the need for additional filling work.

[0078] Embodiment 6, as Figure 15 shown, the difference from Embodiment 5 is that four positioning grooves 17 are provided on the lower bottom surface of the flange edge 14. The positioning grooves 17 are located near the corners of the flange edge 14, and the positioning grooves 17 are perpendicular to the lower bottom surface of the flange edge 14; four positioning protrusions 2102 are provided on the upper surface of the top plate 2101. The positioning protrusions 2102 are perpendicular to the upper surface of the top plate 2101. During installation, when the corner of the formwork shell 10 is placed on the adjustable support 21, the positioning grooves 17 of the formwork shell 10 and the positioning protrusions 2102 of the adjustable support 21 are paired and connected, which can realize the rapid positioning of the formwork shell 10, avoid the formwork shell 10 from moving horizontally, and there is no need for bolt connection, resulting in less installation workload. In other embodiments, the number of positioning protrusions 2102 can be one or more, ensuring that the positioning protrusions 2102 are inserted into the positioning grooves 17 of any one of the four adjacent formwork shells 10. Since the adjacent formwork shells 10 are firmly connected to each other through fasteners passing through the connection holes 16 and are connected into a whole, positioning one formwork shell 10 through one positioning protrusion 2102 will also limit the horizontal movement of other formwork shells 10. Compared with Embodiment 2, the number of positioning protrusions 2102 and positioning grooves 17 is reduced, making the installation more convenient.

[0079] Embodiment 7 is different from Embodiment 5 in that the flange edge 14 and the supporting bracket 21 are detachably and fixedly connected, including opening through holes in the flange edge 14 and the supporting bracket 21 and fastening them by passing fasteners through the through holes, or opening through holes in the supporting bracket 21 and opening threaded blind holes on the lower surface of the flange edge 14, and only fastening by screwing bolts through the through holes and then into the threaded blind holes.

[0080] In other embodiments, the size of the general standard formwork 10 is 1200 mm, and non-standard formworks 10 will be prefabricated according to the requirements of the drawings. The sizes of the standard formworks 10 are all the same. The differences between the non-standard formworks 10 and the standard formworks 10 lie in their lengths and widths. When prefabricating the formworks 10, it should be noted that the positions of the connecting holes 16 of the non-standard formworks 10 and the standard formworks 10 need to be able to coincide. And the spacing between the vertical rods 23 under the standard formwork 10 is also 1200 mm, and there are standard disk buckle type cross bars 25. Therefore, the vertical rods 23 under the standard formwork 10 are connected by disk buckle type connections, and the cross bars 25 between the vertical rods 23 under the non-standard formwork 10 are connected by disk buckle type connections or cross fasteners.

[0081] In other embodiments, when the height of the vertical rod 23 is too high, diagonal tension rods are also provided between the vertical rods 23 to increase the stability of the vertical rod 23.

[0082] In actual application, after the formwork 10 is erected, steel bars are tied, concrete is poured, and cured on the erected high-efficiency assembled ribbed floor forming structure. After curing and forming, the fasteners are removed, the height of the supporting bracket 21 is reduced, and the formwork 10 and the entire supporting assembly 20 are removed for turnover and repeated use.

[0083] In summary, the high-efficiency assembled ribbed floor forming structure described in the present invention can achieve rapid assembled construction, with low workload, and the installation position of the supporting bracket 21 is more accurate, without adjustment or rework. The surface of the ribbed floor is flat after demoulding and does not require secondary processing.

[0084] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments are only for explaining the technical concept and features of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
