Description

Technical Field

[0001] The utility model relates to the technical field of building formwork, and particularly relates to a flat floor forming structure which is convenient to disassemble and assemble. Background Art

[0002] A flat formwork is a formwork used in building engineering and is mainly used for the construction of cast-in-place concrete flat floors.

[0003] In the prior art, generally, a full hall scaffold is pre-erected, wooden boards are laid above the scaffold, and flat formwork is laid flat above the wooden boards. This method has the following problems:

[0004] First, the laying density of the full hall scaffold is relatively dense, the erection is cumbersome, and the labor cost is relatively high.

[0005] Second, after the full hall scaffold is laid, it cannot be passed below, and workers can only climb to work, so the safety is relatively low.

[0006] Third, the height adjustment of the full hall scaffold is inconvenient, and the vertical poles of each scaffold need to be adjusted separately.

[0007] Fourth, only the flat formwork can be reused, and there are relatively few reusable components. 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 such as huge workload, relatively low safety, inconvenient height adjustment, and few reusable components. Now the utility model provides a flat floor forming structure which is convenient to disassemble and assemble.

[0009] The utility model is realized by the following technical solutions. A flat floor forming structure which is convenient to disassemble and assemble includes a plurality of formworks, columns, and crossbeams.

[0010] The formwork includes a formwork top surface, the formwork top surface is rectangular, a formwork side surface extending downward is connected to the periphery of the formwork top plate, the formwork side surface is perpendicular to the formwork top surface, a cavity is formed between the formwork top surface and the surrounding formwork side surfaces, and connection holes are arranged on two or three or four adjacent formwork side surfaces of the formwork. The connection holes are horizontally arranged and penetrate from the cavity to the formwork side surface.

[0011] The formwork side surfaces of a plurality of formworks are attached to each other in pairs to form a rectangular formwork array with multiple rows and multiple columns. The lower bottom surfaces of all formworks are coplanar. The positions of the connection holes on the formwork side surfaces of two adjacent formworks cooperate with each other, and are fixedly connected by fasteners passing through the connection holes.

[0012] The four sides of the bottom surface of the template are defined as long sides and short sides according to their lengths. A plurality of cross beams are arranged in parallel, and the cross beams support at least the common sides of two adjacent rows of templates in the template array. The common sides are the long sides or short sides of the templates.

[0013] One column is arranged under each end of the cross beam. The bottom of the column supports on the floor surface. The column can be adjusted in height. The top of the column is detachably connected or lapped with the cross beam. Each column and the adjacent columns are connected into a whole through a connecting piece.

[0014] Further, according to different working conditions, the outermost edge of the template array is lapped on the side form of the main beam, or on the independent support, or on the cross beam.

[0015] Further, the independent support includes a support rod and a top plate. The bottom of the support rod supports on the floor surface. The support rod can be adjusted in height. A top plate is arranged at the top of the support rod. The top plate abuts against the bottom surface of the edge or corner of the outermost edge of the template array. The support rod and the adjacent support rods, and the adjacent columns are connected into a whole through a connecting piece.

[0016] The cross beam is one of a profiled steel, a steel truss beam, a cantilever beam or a combination thereof. The profiled steel includes a square pipe, an I-beam, and an H-beam, as long as the bearing capacity and the bending strength meet the design requirements.

[0017] The column is formed by scaffolding and includes a vertical rod, a horizontal rod, and a top bracket. The top bracket is used to support the cross beam.

[0018] The vertical rod is provided with a detachable circular connecting plate. The two ends of the horizontal rod are connected to the connecting plate of the vertical rod through pins.

[0019] The connecting piece is a horizontal rod for scaffolding.

[0020] The cross beam is a steel truss beam, which is welded by a plurality of square pipes. The top bracket includes a lead screw, an adjusting nut, and a U-shaped supporting plate. The lead screw is meshed with the adjusting nut. The lead screw is inserted into the top of the vertical rod. A U-shaped supporting plate is arranged at the top end of the lead screw. The U-shaped supporting plate positions and supports the square pipe of the steel truss beam.

[0021] The steel truss beam is an integral non-detachable unit, or is spliced by two detachable sections.

[0022] Grid-shaped reinforcing ribs are arranged inside the top surface and the side surface of the template, which can ensure that the template realizes a relatively high overall strength with less consumables.

[0023] The beneficial effects of the present utility model are:

[0053] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0054] Example 1

[0055] As Figures 1-7As shown, a flat floor forming structure with convenient disassembly and assembly includes a formwork 10, columns 20, and cross beams 30.

[0056] The construction background of this solution is that the four surrounding walls have been built, and formwork needs to be laid to prepare for the pouring of the floor slab. This solution uses the formwork 10, columns 20, and cross beams 30.

[0057] As Figures 1-2 shown, the formwork 10 includes a formwork top surface 11, which is rectangular. A formwork side surface 12 extending downward is connected to the periphery of the top plate of the formwork 10. The formwork side surface 12 is perpendicular to the formwork top surface 11. The formwork top surface 11 and the surrounding formwork side surface 12 form a cavity. Connecting holes 13 are provided on two or three or four adjacent formwork side surfaces 12 of the formwork 10. The connecting holes 13 are horizontally arranged and penetrate from the cavity to the formwork side surface 12. Mesh-shaped reinforcing ribs are arranged inside the formwork top surface 11 and the formwork side surface 12, which can ensure that the formwork 10 achieves a relatively high overall strength with less consumables.

[0058] The formwork side surfaces 12 of several formworks 10 are attached to each other in pairs to form a rectangular formwork array. For the formwork array at the corner of the formwork array, two formwork side surfaces 12 are provided with connecting holes 13. For the formwork 10 on the side, three formwork side surfaces 12 are provided with connecting holes 13. For the formwork 10 in the center, all four formwork side surfaces 12 are provided with connecting holes 13, ensuring that there are no connecting holes 13 on the formwork side surfaces 12 on the periphery of the formwork array, or that any formwork 10 has four formwork side surfaces 12 provided with connecting holes 13. The formwork side surfaces 12 on the periphery of the formwork array are blocked with plugs, which can prevent the leakage of slurry from the peripheral connecting holes 13 and ensure the surface flatness of the building after demoulding.

[0059] The lower bottom surfaces of all the templates 10 are coplanar. The positions of the connecting holes 13 on the template side surfaces 12 of two adjacent templates 10 are matched with each other, and are fixedly connected by fasteners passing through the connecting holes 13. In this solution, the width of the square space enclosed by the four walls is 7200 mm. In this solution, 27 templates 10 with a length of 2400 mm and a width of 800 mm are used to form an arrangement of three rows and seven columns, and the size just matches the square space. The side surfaces of the template array abut against the side surfaces of the four walls. Seven cross beams 30 are arranged below the template array. The seven cross beams 30 are arranged in parallel. Among them, two cross beams 30 separately support the bottom surfaces of the templates on the outermost two sides of the template array. Two of the cross beams 30 support the common edge of the two short sides of the three rows of templates. And the other three cross beams 30 support the middle part of the three rows of templates 10. The steel truss beam is an integral non-detachable unit, or is composed of two detachable sections spliced together. In this solution, the steel truss beam is welded into an integral unit. In this solution, the cross beam 30 adopts a steel truss beam structure, which is welded by four parallel square tubes plus a number of straight braces and diagonal braces. Under the same load-bearing requirements and bending resistance requirements, the weight of the steel truss beam is lower, which has a cost advantage, and the requirements for the bearing capacity of the hoisting tool are lower, making it more convenient for installation.

[0060] One column 20 is arranged below each end of the cross beam 30. The bottom of the column 20 is supported on the floor surface. The column 20 can be adjusted in height. The top of the column 20 is detachably connected or lapped with the cross beam 30. Each column 20 and the adjacent column 2 are connected into an integral unit through a connecting member. The connecting member is a cross bar 22 for a scaffold. In this solution, the column 20 is formed by scaffolding, including a vertical rod 21, a cross bar 22, and a top bracket 23. A detachable circular connecting plate 24 is arranged on the vertical rod 21. The two ends of the cross bar 22 are connected to the connecting plate 24 of the vertical rod 21 through pins. The top bracket 23 includes a lead screw 231, an adjusting nut 232, and a U-shaped supporting plate 233. The lead screw 231 is meshed with the adjusting nut 232. The lead screw 231 is inserted into the top of the vertical rod 21. A U-shaped supporting plate 233 is arranged at the top end of the lead screw 231. The U-shaped supporting plate 233 positions and supports the square tube of the steel truss beam. By rotating the adjusting nut 232, the length of the lead screw 231 extending out of the vertical rod 21 can be adjusted, thereby changing the height of the U-shaped supporting plate 233 and adjusting the height of the cross beam 30 to meet the requirements of construction. Of course, in other embodiments, the top bracket 23 can also be set to other structures as long as it can play a role in supporting the cross beam.

[0061] In this solution, the columns 20 are erected on-site. Two columns 20 support a crossbeam 30. The crossbeam 30 is a prefabricated component and is hoisted as a whole. Finally, the formwork 10 is laid on the crossbeam 30 and connected pairwise through fasteners. The entire installation process is very convenient, without the need to erect a full hall scaffold, with less workload. And precisely because there is no full hall scaffold, during the erection process, workers can operate standing on a mobile platform, which is safer compared to climbing on a scaffold for installation. Moreover, the formwork 10 is connected through fasteners, with a tight connection and no leakage of mortar.

[0062] The specific construction method of this solution:

[0063] Before the construction of this solution, the formwork 10 and the crossbeam 30 are prefabricated according to the construction requirements, and the parts required for the columns 20 are prepared. The construction process includes installing the columns 20 and connecting pieces, installing the crossbeam 30, and installing the formwork 10. The columns 20, the crossbeam 30, and the formwork 10 adopt the structure of Embodiment 1. Specifically:

[0064] I. Erect the columns 20: Erect fourteen columns 20 near the wall. The fourteen columns 20 are arranged in two parallel rows. The two rows of columns 20 are respectively near two opposite walls. The center distance between every five adjacent columns 20 in the middle of each row is the same as the width of the supported formwork 10. The two outermost columns 20 are set near the corner, and each column 20 is connected to the adjacent column 20 through a connecting piece to form a whole; each column 20 is composed of four vertical rods 21, several horizontal rods 22, and a jack 23. The center distance of the vertical rods 21 is 300 mm. The vertical rods 21 are connected in a disc-locking manner through the horizontal rods 22. The horizontal rods 22 are fixed at the connecting disc 24 on the vertical rods 21 through pins. The jack 23 includes a lead screw 231, an adjusting nut 232, and a U-shaped supporting plate 233. The adjusting nut 232 is engaged with the lead screw 231. The lower end of the lead screw 231 is inserted into the top of the vertical rod 21. By rotating the adjusting nut 232, the length of the lead screw extending out of the vertical rod 21 can be adjusted, thereby changing the height of the U-shaped supporting plate 233. After the columns 20 are erected, the adjacent columns 20 are fixedly connected through the horizontal rods 22 to ensure the overall stability of the columns 20. Of course, in other embodiments, the jack 23 can also be set to other structures as long as it can play a supporting role for the crossbeam.

[0065] II. Installing the cross beam 30: Lift the seven prefabricated cross beams 30 and install them on the tops of the fourteen columns 20. In this solution, the cross beam 30 adopts a steel truss beam structure, which is welded by four parallel square tubes plus several straight braces and diagonal braces. It is hoisted by a tower crane or other hoisting machinery. Place the square tube of the steel truss beam on the U-shaped support plate 233. Rotate the adjusting nut 232 to adjust the length of the lead screw extending out of the vertical rod 21, thereby changing the height of the U-shaped support plate 233, and finally making the height of the top of the cross beam 30 meet the construction requirements;

[0066] III. Installing the formwork 10: Start installing the formwork 10 from a corner of the four surrounding walls along one side of the wall. Press the formwork side 12 of the formwork 10 against the wall surface, and then successively install the remaining formwork 10 along the side of the already installed formwork 10 or the wall until the formwork 10 covers the area to be laid. The edge of each formwork 10 is placed on the cross beam 30; Starting from the second formwork 10, when installing each formwork 10, press the joint surface 15 of the newly installed formwork 10 and the already installed formwork 10 tightly, and fasten the two formworks 10 through the fasteners penetrating the connection holes 16. In this solution, they are installed row by row in sequence. For example Figure 6 As shown, it is a schematic diagram of two formworks 10 being erected. The first formwork 10 is installed at the corner position, and the second formwork 10 is closely attached to the first formwork 10, and then gradually erected along a horizontal row, as Figure 7 shown, the formwork 10 covers the entire plane.

[0067] In this solution, the columns 20 are erected on-site. The columns 20 adopt a disc buckle type scaffold, and the installation is very convenient. The cross beam 30 is hoisted as a whole. Two columns 20 support one cross beam 30. Finally, the formwork 10 is laid on the cross beam 30 and fastened to each other through fasteners. The entire installation process is very convenient. There is no need to erect a full hall scaffold, and the workload is small. It can be assembled quickly. And precisely because there is no full hall scaffold, during the erection process, workers can operate on a mobile platform, which is safer than climbing on the scaffold for installation. The formworks 10 are connected through fasteners penetrating the connection holes, and the connection is tight without leakage of mortar. The columns 20, cross beams 30, and formworks 10 can all be reused. After being used multiple times, the cost can be spread very low.

[0068] Embodiment 2

[0069] As Figure 8As shown, the difference from the first embodiment is that the number of the cross beams 30 is four. Two of the cross beams 30 separately support the bottom surfaces of the short sides of the outermost two templates 10 on both sides of the template array, and the other two cross beams 30 support the common sides of the two short sides of three rows of templates. There is no support in the middle of the long side of the template 10. In this solution, the self-strength of the template 10 is sufficient to support the concrete above, so the support in the middle of the long side of the template 10 can be cancelled to reduce costs.

[0070] Embodiment Three

[0071] As Figures 9-10 shown, the difference from the first embodiment is that the cross beam 30 is slightly shorter than the spacing of the walls, so an additional row of independent supports 60 is added. The independent support 60 includes a support rod 61 and a top plate 62. The bottom of the support rod 61 is supported on the floor surface. The support rod 61 can be adjusted in height. A top plate 62 is provided at the top of the support rod 61. The top plate 62 abuts against the bottom surface of the edge or corner of the outermost edge of the template array. The support rod 61 is connected to the adjacent support rod 61 and the adjacent column 20 by a connecting piece to form an integral body. The cross beam 30 is prefabricated and recycled among multiple projects. Therefore, the cross beam 30 is generally prefabricated into multiple standard lengths, such as 6m / 8m, etc. The standard length of some cross beams 30 may be just right in the previous project, but just a little shorter in the next project. If the cross beam 30 is customized separately for each project to completely match the span, the cost will increase a lot. Therefore, this solution adopts the combination of the cross beam 30 and the independent support 60, which can be applicable to various span scenarios and is more flexible.

[0072] Embodiment Four

[0073] As Figure 11 shown, the difference from the first embodiment is that there are ten cross beams 30, and the cross beams 30 are supported under the long sides of the templates 10, which is applicable to the scenarios where the self-strength of the templates 10 is weak or the load is large.

[0074] Embodiment Five

[0075] As Figure 12 shown, the difference from the first embodiment is that the construction background of this solution is that the four surrounding walls are not built, and the main beam templates and the main beam side forms 41 around have been erected. Therefore, the outermost edge of the template array can be set on the main beam side form 41, and the column 20 and the main beam scaffolding 42 are connected into an integral body by a cross bar.

[0076] Embodiment Six

[0077] As Figure 13As shown in the figure, the difference from the first embodiment is that the cross beam 30 adopts a steel truss beam structure, and its front view is a triangular frame. It can also meet the design requirements for flexural strength, has a relatively high bearing capacity, and a relatively low production material cost.

[0078] Embodiment Seven

[0079] As Figure 14 shown in the figure, the difference from the first embodiment is that the cross beam 30 adopts an H-shaped steel. Compared with the cross beam 30 structure in the above embodiments, the H-shaped steel is convenient for obtaining materials and has a relatively low processing cost. Only selection is needed, and then an appropriate length is cut to complete.

[0080] Embodiment Eight

[0081] As Figure 15 shown in the figure, the difference from the first embodiment is that the cross beam 30 adopts a cantilever beam structure. Compared with the cross beam 30 structure in the above embodiments, the cantilever beam can adjust the tension of the tension chord according to the load, so that the flat plate at the top of the cantilever beam bulges slightly upward when there is no load. After pouring concrete, the flat plate at the top of the cantilever beam will be under pressure and change from slightly bulging to just keeping horizontal. Compared with the above embodiments, the cross beam 30 is less worried about the influence of force deformation, and the construction accuracy of the ribbed floor is higher.

[0082] In other embodiments, the cross beam 30 can adopt other structures, including I-beams, square tubes, etc. The cross beam 30 only needs to meet the designed flexural strength, ensure that during grouting, the cross beam 30 can bear the weight of the concrete, and the bending amplitude is within the acceptable design range.

[0083] In other embodiments, the independent support 60 includes support bars installed on the wall, which can also support the edge of the formwork array.

[0084] In other embodiments, the vertical rods 21 of each column 20 can also be arranged in a total of 6 (2×3), or 8 (2×4), or even 9 (3×3) according to needs, as long as the design requirements are met.

[0085] In other embodiments, the column 20 can also adopt a prefabricated steel truss structure and be assembled on site by bolts.

[0086] In summary, the disassembled and assembled convenient flat floor forming structure of the present utility model can reduce the installation quantity of the scaffolding, reduce the workload. Through the erection of the columns 20 and the cross beams 30, the installation conditions of the formwork 10 can be quickly met, and there is no full hall scaffolding below. The self-propelled hydraulic lifting vehicle can pass unimpeded, which can improve the installation efficiency of the installation workers, and there is no need to climb the scaffolding, which is safer.

[0087] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the above embodiments are only for explaining the technical concept and features of the present utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it. It should not be used to limit the protection scope of the present utility model. Any equivalent changes or modifications made according to the spirit of the present utility model should be covered within the protection scope of the present utility model.
