Description

Technical Field

[0001] The utility model relates to the field of terrace casting templates, in particular to a combined small steel template for an arc-shaped terrace. Background Art

[0002] In order to improve their aesthetics and novelty, some buildings will adopt the construction plan of rounded balconies. In the casting construction process of rounded balconies, wooden formwork is currently widely used because the production cost of wooden formwork is relatively low, and the wooden formwork is light, the transportation cost is low, and it is more convenient to carry and install. It can also ensure the personal safety of workers when building the formwork on the construction site. However, for the arc of the rounded balcony, the wooden formwork needs to be bent into an arc and fixed to form the rounded corner structure of the balcony. This method is not conducive to ensuring the design accuracy of the balcony rounded corners, and for the rounded balconies with special structures such as lower convex edges, the adaptability of wooden formwork is even worse.

DETAILED DESCRIPTION

[0017] Example 1, see the attached specification Figure 1-4 A combined small steel formwork for an arc-shaped terrace comprises an outer arc formwork 11, a bottom plate 12 and an inner arc formwork 13. The outer arc formwork 11 and the inner arc formwork 13 are arranged concentrically, and the bottom plate 12 is fan-shaped as a whole. The outer edge of the bottom plate 12 is fixedly connected to the bottom surface of the outer arc formwork 11, and a convex edge formwork arranged concentrically with the outer arc formwork 11 is provided on the inner edge of the bottom plate 12. The position of the convex edge formwork is lower than the bottom plate 12 of the balcony, and a casting gap 15 is provided between the convex edge formwork and the inner arc formwork 13. The balcony plane is connected with the internal space of the convex edge formwork through the casting gap 15. Therefore, after pouring concrete, the outer edge of the balcony bottom plate 12 can form a convex edge protruding downward, which is not only more beautiful, but also can prevent rainwater from flowing into the balcony below along the balcony bottom plate 12.

[0018] The flange template of this embodiment is formed by fixing and splicing an upper template body 141 and a lower template body 142. This upper and lower assembled structure can reduce the size of the flange template, facilitate movement and transportation, and is not prone to deformation of the flange template due to collision.

[0019] The upper end surface of the upper template body 141 is vertically provided with a transverse extension plate 131, which is used to support the template system connected to the balcony bottom plate 12 to improve the stability of the connection between the combined small steel template 17 and the main template system of the balcony.

[0020] The outer arc template 11 includes a number of small arc plates 111 connected to each other at both ends. These small arc plates 111 are not easy to bend and deform, and are easy to carry. A reinforcing plate armor 112 is provided on the edge of the outer side surface of the small arc plate 111. A number of docking holes 113 are evenly spaced on the reinforcing plate armor 112. Fasteners are inserted between the docking holes 113 of adjacent reinforcing plate armors 112 to achieve a fixed connection between the small arc plates. The reinforcing plate armor 112 is not only used to improve the deformation resistance of the small arc plate 111, but also used to improve the connection strength between the small arc plates 111.

[0021] A reinforcing plate B 132 is provided at the edge of the outer side surface of the inner arc-shaped template 13 , and a plurality of docking holes B 133 are provided on the reinforcing plate B 132 . The function of the reinforcing plate B 132 is the same as that of the reinforcing plate A 112 .

[0022] A plurality of docking holes 121 are provided at the inner and outer arc edges of the bottom plate 12, and fasteners are inserted between the docking holes 121 and the docking holes 113 on the reinforcing plate 112 at the bottom of the small arc plate body 111. Docking folding plates 122 are provided at both ends of the bottom plate 12, and the docking folding plates 122 are used to dock with the templates on both sides.

[0023] When assembling the combined small steel mold 17 of the utility model, a pin is inserted between the docking hole A 113 of the reinforcing plate of the small arc plate body 111 of the wheel to quickly form the outer arc template 11, and the reinforcing plates of each small arc plate body 111 correspond to the docking holes C 121 on the bottom plate 12 and the pins are inserted to connect the outer arc template 11 and the bottom plate 12, and then the convex edge template is installed in the same way, and the inner arc template 13 is supported by the support to form a casting gap 15, so as to form a mold structure of the rounded corners of the balcony in a combined assembly manner. This steel mold structure is stable and has high strength, and will not cause mold expansion and deformation, so it can well ensure the design accuracy of the rounded corners of the balcony.
