Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a series of formwork installation structures. 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] Traditional formwork structures have a single size, making it difficult to flexibly adapt to complex construction layouts. They often require custom-made irregular components, which significantly increases costs and construction time. At the same time, the lack of a unified design between formworks makes them prone to misalignment during installation, and the risk of grout leakage is prominent during the pouring process. Utility Model Content

[0004] The problem solved by this utility model is that the traditional mold shell structure in the prior art has a single size and is difficult to flexibly adapt to complex construction layouts. This utility model provides a series of mold shell installation structures that can be flexibly assembled.

[0005] This utility model is achieved through the following technical solution: a series of mold shell installation structures, including a first mold shell, a second mold shell, and a third mold shell. Each of the first, second, and third mold shells has a top surface. A downwardly extending side surface is connected around the top surface. The top surface and the enclosing side surface form a cavity. The lower edge of the side surface extends horizontally outward to form a flange. The outer contour of the flange is rectangular. The vertical end face of the free end of the flange is the mating surface where the mold shells abut against each other. The mating surface has a connecting hole, which is horizontally positioned, extending from the cavity to the mating surface, and perpendicular to the mating surface.

[0006] The length or width of the mold shell is defined as the distance from one mating surface to its opposite mating surface.

[0007] The length of the first mold shell is A, and the width is A.

[0008] The second mold shell has a length of A and a width of B.

[0009] The length of the third mold shell is B, and the width is B.

[0010] The connecting holes on the mating surfaces of the first, second, and third mold shells with the same side length are positioned identically.

[0011] The relationship between A and B is: A = aL, B = bL, where a and b are positive integers, ab = 1 or 2, and L is the basic unit length.

[0012] There are a number of connection holes on the mating surface with side length A. Each connection hole is arranged at equal intervals L, and the distance from the outermost connection hole to the right angle of the flange edge is L / 2.

[0013] There are b connecting holes on the mating surface with side length B. Each connecting hole is arranged at equal intervals L, and the distance from the outermost connecting hole to the right angle of the flange edge is L / 2.

[0014] During assembly, the first mold shell, the second mold shell, and the third mold shell are arranged in a rectangular array, with mating surfaces of the same side length touching each other, and connected by fasteners passing through the connecting holes of adjacent mold shells. The second mold shells are arranged in one or more rows horizontally and one or more columns vertically, with the third mold shell installed at the intersection of the horizontal columns, and the first mold shell installed at the remaining positions.

[0015] Furthermore, each mating surface has one or more connection holes.

[0016] Furthermore, the height distance from all connection holes to the bottom surface of the flange edge is consistent.

[0017] Furthermore, the value of L ranges from 200 to 400 mm.

[0018] Furthermore, the connecting hole has a chamfer at the opening of the mating surface for guidance.

[0019] The beneficial effects of this utility model are:

[0020] This invention achieves modularity, high compatibility, and easy assembly through standardized dimensions and hole design. At the same time, the scientific hole arrangement and size ratio optimize structural strength and layout flexibility, significantly reducing customization requirements, lowering manufacturing costs, and supporting efficient and reliable on-site installation.

[0029] 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.

[0030] Example 1

[0031] like Figure 1-2 As shown, a series of mold shell mounting structures includes a first mold shell 100, a second mold shell 200, and a third mold shell 300. Each of the first mold shell 100, second mold shell 200, and third mold shell 300 has a top surface 101. A downwardly extending side surface 102 is connected around the top surface 101. The top surface 101 and the enclosing side surface 102 form a cavity. The lower edge of the side surface 102 extends horizontally outward to form a flange edge 103. The outer contour of the flange edge 103 is rectangular. The vertical end face of the free end of the flange edge 103 is the mating surface 104 between the mold shells. The mating surface 104 is provided with a connecting hole 105. Each mating surface 104 has one or more connecting holes 105. The height distance from all connecting holes 105 to the bottom surface of the flange edge 103 is the same. The connecting hole 105 is horizontally arranged to pass through the cavity to the mating surface 104 and is perpendicular to the mating surface 104. The connecting hole 105 has a chamfer at the opening of the mating surface 104 for guidance, which facilitates the insertion of fasteners.

[0032] The length or width of the mold shell is defined as the distance from one mating surface 104 to its opposite mating surface 104.

[0033] The length of the first mold shell 100 is A, and the width is A.

[0034] The second mold shell 200 has a length of A and a width of B.

[0035] The third mold shell 300 has a length of B and a width of B.

[0036] The relationship between A and B is as follows: A = aL, B = bL, where a and b are positive integers, ab = 1 or 2, and L is the basic unit length.

[0037] In this embodiment, L is 300mm, a=4, b=3, therefore: Figure 1 As shown,

[0038] The length of the first mold shell 100 is A, specifically 1200 mm, and the width is A, specifically 1200 mm.

[0039] The second mold shell 200 has a length A, specifically 1200 mm, and a width B, specifically 900 mm.

[0040] The length of the third mold shell 300 is B, specifically 900 mm, and the width is B, specifically 900 mm.

[0041] The connecting holes 105 on the mating surfaces 104 of the first mold shell 100, the second mold shell 200, and the third mold shell 300 with the same side length are in the same position. Specifically: the number of connecting holes 105 on the mating surface 104 with side length A is a, and each connecting hole 105 is arranged at equal intervals L, and the distance from the outermost connecting hole 105 to the right angle of the flange edge 103 is L / 2; the number of connecting holes 105 on the mating surface 104 with side length B is b, and each connecting hole 105 is arranged at equal intervals L, and the distance from the outermost connecting hole 105 to the right angle of the flange edge 103 is L / 2.

[0042] Specifically, the mating surface 104 with a side length of 1200mm has 4 connecting holes 105, each connected hole 105 is arranged at equal intervals of 300mm, and the distance from the outermost connecting hole 105 to the right angle of the flange edge 103 is 150mm; the mating surface 104 with a side length of 900mm has 3 connecting holes 105, each connected hole 105 is arranged at equal intervals of 300mm, and the distance from the outermost connecting hole 105 to the right angle of the flange edge 103 is 150mm.

[0043] In this embodiment, scaffolding is erected in advance, and the formwork is placed on the scaffolding. The supporting components of the scaffolding support the flange edge 103 of the formwork. During assembly, 25 first formworks 100, 10 second formworks 200, and 1 third formwork 300 are required, arranged in a rectangular array, such as... Figure 2As shown, the mating surfaces 104 of the same side length are abutted together and connected by fasteners passing through the connecting holes 105 of adjacent mold shells. The second mold shells 200 are arranged in a longitudinal column and a transverse row, with a third mold shell 300 at the intersection and the remaining positions occupied by first mold shells 100. The flange edges 103 of the same side length are abutted together, ensuring the connecting holes 105 are aligned, facilitating the fasteners to pass through the connecting holes 105 and secure adjacent mold shells. The final assembly forms a 6900mm*6900mm mold shell array. After being connected as a whole by fasteners, the mating surfaces 104 of the mold shells are tightly fitted together, preventing gaps and grout leakage. Furthermore, the integrated mold shell structure is more stable, improving construction safety.

[0044] This solution achieves modularity, high compatibility, and easy assembly through standardized dimensions and hole design (based on unit L). At the same time, the scientific hole arrangement (equal spacing, edge offset) and size ratio (ab=1) optimize structural strength and layout flexibility. This solution significantly reduces customization requirements, lowers manufacturing costs, and supports efficient and reliable on-site installation.

[0045] Example 2, as Figure 3 As shown, the difference from Embodiment 1 lies in the quantity of the first mold shell 100, the second mold shell 200, and the third mold shell 300. There are 16 first mold shells 100, 16 second mold shells 200, and 4 third mold shells 300. During assembly, the second mold shells 200 are arranged in two vertical columns and two horizontal rows, with four third mold shells 300 at the intersections, and the remaining positions are occupied by first mold shells 100. Compared to Embodiment 1, the horizontal and vertical widths of the mold shell array are both 300mm smaller, resulting in a final assembled mold shell array of 6600mm*6600mm. This demonstrates the flexible adjustment capabilities of this solution.

[0046] Example 3, as Figure 4-5 As shown, the difference from Embodiment 2 is that the quantity and size of the second mold shell 200 and the third mold shell 300 have changed. For example... Figure 4 As shown, the second mold shell 200 has dimensions of 1200mm * 600mm, and the third mold shell 300 has dimensions of 600mm * 600mm. The mating surface 104, with a side length of 600mm, has two connecting holes 105, spaced 300mm apart. The distance from the edge connecting hole 105 to the right angle of the flange edge 103 is 150mm. There are 25 first mold shells 100, 10 second mold shells 200, and 1 third mold shell 300. During assembly, as... Figure 5As shown, the second mold shells 200 are arranged in a vertical column and a horizontal row, with a third mold shell 300 at the intersection, and the remaining positions are all first mold shells 100. Compared with Embodiment 2, the horizontal and vertical widths of the mold shell array remain unchanged, but the two rows and two columns of 1200mm*900mm are replaced with one row and one column of 1200mm*600mm and one row and one column of 1200mm*1200mm, demonstrating the flexible adjustment performance of this solution.

[0047] Example 4, as Figure 6-7 As shown, the difference from the above embodiment is that: the basic unit length L changes, L is 400mm, the size of the first mold shell 100 is 1200mm*1200mm, the size of the second mold shell 200 is 1200mm*800mm, the size of the third mold shell 300 is 800mm*800mm, the number of connecting holes 105 on the 1200mm side surface 104 is 3, each connecting hole 105 is arranged at equal intervals of 400mm, and the distance from the outermost connecting hole 105 to the right angle of the flange edge 103 is 200mm; the 800mm side surface 104 There are two upper connecting holes 105, each equally spaced at 400mm intervals. The distance from the outermost connecting hole 105 to the right angle of the flange edge 103 is 200mm. During assembly, 20 first mold shells 100, 14 second mold shells 200, and 2 third mold shells 300 are required, arranged in a rectangular array. The mating surfaces 104 of the same side length are mated together and connected by fasteners passing through the connecting holes 105 of adjacent mold shells. The second mold shells 200 are arranged in two vertical columns and one horizontal column, with two third mold shells 300 at the intersection, and the remaining positions are occupied by first mold shells 100. The mating of flange edges 103 of the same side length ensures that the connecting holes 105 are in the same position, facilitating the fasteners to pass through the connecting holes 105 to secure adjacent mold shells. The final assembly results in a mold shell array of 6400mm*6800mm.

[0048] This solution mainly explains that L determines the specification gradient of the series of formwork shells. The smaller the value of L, the more detailed the formwork shell specifications are, and the closer they are to the span required by the actual floor slab. However, the types of formwork shells will increase accordingly, which will increase the variety of formwork shells available for stock. Generally speaking, the value of L is around 200-400mm, with 300mm being the preferred option. This solution demonstrates the flexible adjustment performance of this solution.

[0049] In summary, the series of mold shell installation structures described in this utility model achieves modularity, high compatibility, and easy assembly through standardized dimensions and hole design. At the same time, the scientific hole arrangement and size ratio optimize the structural strength and layout flexibility, significantly reducing customization requirements, lowering manufacturing costs, and supporting efficient and reliable on-site installation.
