Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a modular building formwork. Background Technology

[0002] Ribbed floor slab formwork is a type of formwork used in building construction. It is mainly used for the construction of cast-in-place two-way ribbed floor slabs (floor slabs) and is suitable for construction of large-span and high-load spaces, such as underground garages, large shopping malls, multi-story factories, school buildings, and civil defense projects.

[0003] However, traditional formwork is prone to problems during assembly, such as inaccurate positioning, uneven joints leading to grout leakage, unstable horizontal connections, and reliance on additional fasteners, which affect construction speed and molding quality. Utility Model Content

[0004] The problem solved by this utility model is that existing modular formwork is prone to problems such as inaccurate positioning, uneven joints leading to grout leakage, unstable horizontal connection, and reliance on additional fasteners during assembly, which affect construction speed and forming quality. This utility model provides a modular building formwork that is easy to install and has precise positioning.

[0005] This utility model is achieved through the following technical solution: a modular building formwork, including a top surface of the formwork, with downwardly extending side surfaces of the formwork connected around the top surface. The top surface and the enclosing side surfaces form a cavity. The lower edge of the side surfaces extends horizontally outward to form a flange. The outer contour of the flange is rectangular, and the vertical end face of the free edge of the flange serves as the mating surface for the interlocking parts of the formwork.

[0006] The mating surface is provided with an outwardly protruding tenon and a mortise that matches the shape of the tenon. At least part of the tenon has a width away from the mating surface that is greater than the width of the tenon at the mating surface. The positions of the tenon and the mortise satisfy the following: when the corners of adjacent mold flange edges are aligned and the mating surfaces are in contact, the tenon just falls into the mortise.

[0007] Furthermore, only tenons are provided on two adjacent mating surfaces, and only mortises are provided on the other two mating surfaces.

[0008] Furthermore, only tenons are provided on the two mating surfaces, while only mortises are provided on the other two mating surfaces.

[0009] Furthermore, each mating surface is alternately provided with tenons and mortises.

[0010] Furthermore, the tenon and mortise are tapered on all three sides.

[0011] Furthermore, the distance from the distal end of the tenon to the mating surface is ≤5cm.

[0012] Furthermore, the bonding surface is provided with a connecting hole, which is horizontally positioned to extend from the cavity to the bonding surface and is perpendicular to the bonding surface.

[0013] Furthermore, the tenon is a non-through groove with the opening facing downwards, the bottom surface of the tenon is flush with the bottom surface of the flange edge, and the top surface of the tenon is lower than the top surface of the flange edge.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model achieves rapid and precise alignment and assembly of adjacent mold shells through the specific layout of tenons and mortises on the flange edge mating surface, and can complete a stable horizontal connection without tools, ensuring that the joints are flush.

[0016] 2. This utility model uses mortise and tenon joints to ensure close contact between the mating surfaces, and combined with subsequent sealing with tape, it significantly reduces the risk of grout leakage between the mold shells and improves the quality of concrete molding.

[0017] 3. This utility model can also adopt a hidden tenon and groove design, which significantly reduces the risk of grout leakage between the mold shells and improves the quality of concrete molding.

[0018] 4. This utility model is also provided with a connecting hole. When the mold shell warps or deforms, it can be connected by fasteners passing through the connecting hole to avoid the adjacent flange edges becoming uneven due to the deformation of the mold shell. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] like Figure 1-2 As shown, a modular building formwork includes a top surface 1, with downwardly extending side surfaces 2 connected around the top surface 1. The top surface 1 and the side surfaces 2 together form a cavity 3. The lower edge of the side surfaces 2 extends horizontally outward to form a flange 4. The outer contour of the flange 4 is rectangular. The vertical end face of the free end of the outer edge of the flange 4 is a mating surface 5 between the formworks. The mating surface 5 is provided with a connecting hole 8, which is horizontally arranged and extends from the cavity 3 to the mating surface 5, and is perpendicular to the mating surface 5.

[0033] The mating surface 5 is provided with an outwardly protruding tenon 6 and a mortise 7 that matches the shape of the tenon 6. At least a portion of the tenon 6 has a width further away from the mating surface 5 than the width of the tenon 6 at its location on the mating surface 5. In this design, the tenon 6 adopts a trapezoidal structure. The distance from the far end of the tenon 6 to the mating surface 5 is generally ≤5cm, and in this design, it is 3.5cm. The positions of the tenon 6 and the mortise 7 satisfy the following condition: when the corners of adjacent mold flange edges 4 are aligned and the mating surfaces 5 are in contact, the tenon 6 falls exactly into the mortise 7. Specifically, in this design, only tenons 6 are provided on two adjacent mating surfaces 5, and only mortises 7 are provided on the other two mating surfaces 5. Each mating surface 5 has three tenons 6 or mortises 7. The mold size in this design is 1200mm*1200mm, the spacing between adjacent tenons 6 / mortises 7 is 400mm, and the distance from the edge tenon 6 / mortise 7 to the right angle of the flange edge 4 is 200mm. During assembly, adjacent formwork shells are laid flat, allowing the tenon 6 to fall into the mortise 7, completing the assembly. This ensures the mating surfaces 5 are aligned and horizontally fixed. After all the formwork shells required for the entire floor slab are assembled, adhesive tape is applied to the mating surfaces 5 to seal the gaps between the formwork shells and prevent grout leakage. If any formwork shell warps or deforms, it can be connected using fasteners through the connecting holes 8 to prevent adjacent flange edges 4 from becoming uneven due to formwork deformation.

[0034] Example 2

[0035] like Figure 3-4 As shown, the difference from Embodiment 1 is that only tenons 6 are provided on the two opposite mating surfaces 5, while only tenons 7 are provided on the other two mating surfaces 5. When assembling the mold shell of this scheme, adjacent mold shells need to be rotated 90°, otherwise it is no different from Embodiment 1, and both can complete the rapid assembly of the mold shell and ensure a stable connection in the horizontal direction.

[0036] Example 3

[0037] like Figure 5-6 As shown, the difference from the above embodiment is that each mating surface 5 is alternately provided with tenons 6 and mortises 7. In this scheme, the order and position of the tenons 6 and mortises 7 on each mating surface 5 remain consistent in the clockwise direction. For example... Figure 5 As shown, looking clockwise, each mating surface 5 consists of a tenon 7, a tenon 6, a tenon 7, and a tenon 6, dividing the mating surface 5 into 5 segments, each segment being 150mm-300mm-300mm-300mm-150mm in length. In Embodiment 1, the direction of the tenons 6 needs to be consistent; in Embodiment 2, the directions of adjacent tenons 6 need to be perpendicular. This embodiment has central symmetry, eliminating the need to pay attention to the direction of the tenons 6 during assembly, making it more convenient.

[0038] Example 4

[0039] like Figure 7-8As shown, this solution is an improvement on Embodiment 1. The tenon 6 has tapered sides, and the mortise 7 has an adaptive tapered shape. This makes it easier to insert during assembly, and when the flange edge 4 is at the same height, the tenon 6 and mortise 7 fit snugly together, providing better connection force. It should be noted that during assembly, one side of the tenon 6 needs to be inserted into the mortise 7 from above, thus requiring a specific assembly sequence.

[0040] Example 5

[0041] like Figure 9-10 As shown, this solution is an improvement on Embodiment 1, featuring a concealed tenon groove 7 design. Specifically, the tenon groove 7 is a non-through groove, with its opening facing downwards. The upper end of the tenon groove 7 does not damage the top surface of the flange edge 4. The bottom surface of the tenon 6 is flush with the bottom surface of the flange edge 4, while the top surface of the tenon 6 is slightly lower than the top surface of the flange edge 4. It is important to note that during assembly, one side of the tenon groove 7 needs to be engaged with the tenon 6 from above, thus requiring a specific assembly sequence. Compared to other embodiments, this solution conceals the gap between the tenon 6 and the tenon groove 7 after assembly, and the gap between the mold shells is only a straight line, reducing the possibility of grout leakage and resulting in a more aesthetically pleasing floor slab after molding.

[0042] In summary, the modular building formwork of this utility model achieves rapid and precise alignment and assembly of adjacent formworks through a specific layout of tenons 6 and mortises 7, enabling stable horizontal connection without tools and ensuring flush joints.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments are only for illustrating the technical concept and characteristics of this utility model, and are intended to enable those skilled in the art to understand and implement the content of this utility model. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
