Technical Field

[0001] The utility model relates to the technical field of hollow plates, in particular to a large-span hollow plate with an outwardly extending upper wing plate and a manufacturing mold thereof. Background Art

[0002] As the construction industry is now focusing on energy and cost efficiency as well as scalable technology, prestressed concrete precast components can meet all these conditions and will play an important role in future-oriented buildings. Hollow slabs are widely used in large-span, large-space, and large-load buildings, such as schools, bridge construction, office buildings, factories, underground parking lots, etc., because of their large span, high load-bearing capacity, strong seismic performance, and the ability to reduce the number of load-bearing walls, beams, and columns, thereby reducing the floor height and increasing the usable area.

[0003] However, for some large-span structures, such as basketball courts or swimming pools, the roof load is large, and the panel surface is discontinuous due to the shape of skylights, etc., which makes it difficult for traditional large-span hollow panels to be flexibly and tightly installed. To this end, those skilled in the art provide a large-span hollow panel with an extended upper wing panel and a manufacturing mold thereof to solve the problems raised in the above background technology.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Please refer to Figure 1 As shown, a large-span hollow slab with an upper wing plate extending outward comprises a hollow slab 1, wherein the hollow slab 1 comprises an upper wing plate 11 and a lower wing plate 12 which are horizontally opposite to each other, and web ribs 13 are arranged between the upper wing plate 11 and the lower wing plate 12 along the span direction, and vertical armatures 4 are arranged at the upper and lower contact ends of the web ribs 13 and the upper and lower contact ends of the upper wing plate 11 and the lower wing plate 12. By arranging the vertical armatures 4 between the upper wing plate 11 and the lower wing plate 12, the load force can be better transferred to the web ribs 13, thereby improving the stability of the integrated structure of the hollow slab 1 and enhancing its load capacity.

[0025] It also includes tensile steel bars built into the junction of the lower wing plate 12 and the web ribs 13. By embedding the tensile steel bars, it can improve the load strength of the overall structure of the hollow slab and enhance the large-span load stability of the hollow slab.

[0026] There is at least one group of holes 3 between the upper wing plate 11 and the lower wing plate 12 separated by the web ribs 13. When there are multiple groups of holes 3, the sizes of the multiple groups of holes 3 may be inconsistent. The number and size of the holes 3 can be set according to the actual use of the hollow plate 1, and their size does not need to be maintained at a uniform size, which can be more flexibly adapted to the on-site installation conditions.

[0027] The upper wing plate 11 is extended to both sides relative to the ribs of the web dense ribs 13, and the lower wing plate 12 is flush with the ribs of the web dense ribs 13. By arranging the upper wing plate 11 to extend outward, the protruding extension part of the upper wing can be more flexibly matched and adapted to large-span building structures, so that the wing plates extending to both sides can be more conveniently matched and adapted to the shapes of skylights and other large-span building structures, thereby improving the overall installation flexibility and adaptability, and can reduce the roof load strength of large-span building structures.

[0028] The hollow slab 1 is divided into an upper and a lower casting layer by the segmented casting point 2. When the hollow slab 1 is constructed, when the lower casting layer is cast to the segmented casting point 2, the casting is stopped to allow the lower casting layer to solidify and take shape, and then the upper casting layer is cast again. After the upper casting layer is formed, a hollow slab 1 with an integrated structure is formed. The segmented casting method can ensure the solidification of the internal casting of the hollow slab 1 and avoid the situation where the internal and external condensation degrees are different due to the internal temperature being too high.

[0029] Please refer to Figure 2 As shown, a manufacturing mold for a large-span hollow slab with an extended upper wing plate comprises an upper template 5 and a horizontally opposite lower template 6, a dense-rib beam 7 is arranged between the upper template 5 and the lower template 6 along the direction of the cross-slab, and a structural rib 8 is arranged between the upper template 5 and the lower template 6 perpendicular to the direction of the cross-slab, and an accommodating cavity is spaced between the upper template 5, the lower template 6, the dense-rib beam 7, and the structural rib 8, and the accommodating cavity can accommodate the hollow slab body, and also comprises vertical axilla plates 9 symmetrically arranged at the connection between the upper template 5 and the dense-rib beam 7, and the lower template 6 and the dense-rib beam 7, the upper template 5 and the lower template 6 are horizontally arranged, and the upper and lower templates are suspended by using the support combination of the dense-rib beam 7 and the structural rib 8, and then the casting accommodating cavity of the hollow slab 1 is formed under the ribs of the vertical axilla plates 9, which serves as a casting molding mold for the hollow slab 1.

[0030] When the hollow slab body is cast, a filling material is pre-placed inside the accommodating cavity. When the hollow slab 1 is cast, a filling material is pre-placed in the accommodating cavity as a filling component for the hole 3 .
