Description

Technical Field

[0001] The invention belongs to the technical field of construction site equipment, and in particular relates to a reinforced ice plate in an ice building, a forming method and a forming device for on-site construction. Background Art

[0002] Ice buildings are ornamental buildings constructed with ice slabs as the main material. Since the load-bearing capacity of the ice slabs themselves is limited, this greatly limits the structural size of the ice building. In order to improve the load-bearing capacity of the ice slabs, the existing technology will deliberately increase the thickness of the ice slabs, which makes the ice building as a whole bloated and affects the aesthetics. The research and development of reinforced ice slabs can well solve the defect of weak load-bearing capacity of traditional ice slabs. It can improve the load-bearing capacity of the ice slabs without increasing the thickness of the ice slabs by implanting reinforcing ribs inside the ice slabs. It is an indispensable and important material for the construction of ice buildings in the future. However, the production of reinforced ice slabs is a relatively large problem. Unlike other building materials, ice slabs have higher environmental requirements and must be well preserved in an environment of minus 5° or lower. In addition, the brittleness of ice slabs is relatively large and it is not easy to transport over long distances. In order to reduce damage to the edges and corners of the ice slabs, ice buildings are constructed in Ice slabs are made at the construction site, and the low temperature environment at the site is used to shape and preserve the ice slabs. The existing ice slab forming method uses an ice slab mold as a shaping device, and the shaping of the ice slab is achieved by pouring layer by layer. There are two disadvantages in preparing reinforced ice slabs in this way. First, pouring layer by layer will make the stratification and gap of the formed ice slab more obvious. Although the ice slab is an integral structure, the overall transparency is low, which affects the aesthetics of the ice slab and subsequent ice buildings. Second, pouring layer by layer can roughly determine the layout position of the reinforcement at a certain level of the ice slab, but the specific and accurate position cannot be grasped, which leads to a large error between the layout position of the reinforcement mesh and the designed position, which will also affect the service life of the reinforced ice slab during the long-term service of the ice slab. Therefore, in order to overcome the above two defects, it is very practical to develop a reinforced ice slab, a forming method and an on-site construction forming device in ice buildings.

[0022] Beneficial effects of the present application compared with the prior art:

[0023] A on - site construction and forming device for a reinforced ice slab in an ice building provided by the present application shapes the ice slab to be prepared through a thermal insulation formwork unit composed of a bottom thermal insulation board and a side thermal insulation frame.

During the forming process of the ice slab, the reinforcing steel mesh is first arranged at the pre-designed height, and then water for ice-making is injected into the thermal insulation formwork unit to the predetermined injection height. Subsequently, the water is frozen and formed through a low-temperature environment. Compared with the layer-by-layer pouring method, through the design optimization of the forming structure, the present application uses a support frame to support and relieve the space pressure of the thermal insulation formwork unit to ensure the stability of the ice slab forming process, enabling the thermal insulation formwork unit to adapt to the tension impact caused by the expansion of the ice body during forming, so as to meet the requirements of hydrostatic ice-making. Hydrostatic ice-making can effectively eliminate the delamination gaps generated by casting ice-making, which is beneficial to improving the overall transparency and aesthetics of the ice slab structure.

Detailed Embodiments

[0034] Detailed Embodiment 1: In combination with Figures 6 to 7To describe this embodiment, a reinforced ice slab in an ice building is provided in this embodiment. The reinforced ice slab includes an ice slab main body 9 and a reinforcing mesh 5. The reinforcing mesh 5 is formed by binding and fixing a plurality of transverse ribs 52 and a plurality of longitudinal ribs 53 that are horizontally and vertically intertwined. A plurality of tie bars 51 are provided vertically at the top of the reinforcing mesh 5. The top end of each tie bar 51 extends to the top of the ice slab main body 9 and is coplanar with the top of the ice slab main body 9. The bottom end of each tie bar 51 is bound and fixed to the corresponding transverse rib 52 or longitudinal rib 53 on the reinforcing mesh 5.

Specifically, longitudinal stressed tie bars 51 are used, and the bond-slip force transmission mechanism is utilized to achieve the coordinated stress of the reinforcement and ice. Distributed reinforcement composed of a plurality of transverse ribs 52 and a plurality of longitudinal ribs 53 is used to achieve a more uniform transmission of the upper load. The ice slab main body 9 is divided into a bottom protective layer ice body 92 of the reinforcement, an end protective layer ice body 93, and a top compression ice body 94 by the reinforcing mesh 5.

Secondly, pass a lifting rope or sling through the inclined hole and anchor it at the bottom of the slab through an anchor plate. Note that the area of the anchor plate is not less than 10 times the area of the hole. Then, cut the tie bars 51 short to the upper surface of the ice slab, and level the top support position of the ice masonry to be arranged with a crushed ice cushion. Finally, lift the ice slab to the designed support position, and spray or sprinkle ice water on the crushed ice cushion between the reinforced ice slab and the ice wall to make it freeze densely. It is necessary to ensure that the length of the longitudinal stressed reinforcement penetrating into the support is not less than 100 mm, and the total support length of the reinforced ice slab is not less than 150 mm.

The bottom thermal insulation board 2 is used for bottom support of the ice slab structure, and the side thermal insulation frame 3 is used for circumferential limitation of the ice slab structure. The forms of the bottom thermal insulation board 2 and the side thermal insulation frame 3 determine the final form of the ice slab.

If the ice slab to be prepared is circular or other polygons, the lengths of the bottom cross braces 1 and the top cross braces 8 are gradually reduced along the shape of the ice slab extension direction. For the convenience of fixing the bottom cross braces 1 and the top cross braces 8 to the end support unit and the side support unit, both ends of the bottom cross braces 1 and both ends of the top cross braces 8 will extend to the outside of the thermal insulation formwork unit to be used as connection parts.
