Problems solved by technology

Among them, the second method is widely used in the construction of long-span ice shell buildings. Most of them use a large airbag as a form-finding and load-bearing template. It is difficult to observe when inflated, the foundation is well anchored, and the interior and exterior of the ice shell cannot be constructed at the same time, etc.

Embodiment 1

[0049] Such as figure 1 As shown, a form-finding and construction method of an air-ribbed ice shell building, comprising:

[0050] S101: Calculate and obtain the architectural data of the ice-shell building, and make a plurality of air-rib arch basic units through the obtained architectural data.

[0051] Specifically, before the ice shell building is manufactured, the air-rib arch basic unit needs to be made in advance, which is mainly based on the design intention of the ice shell building, and the simulation calculation is carried out through finite element analysis software (such as ABAQUS, ANSYS, MSC), so that The architectural data of the ice shell building is calculated, and the architectural data mainly include the overall shape and size of the ice shell building, the number of air-rib arch basic units, the size of a single air-rib arch basic unit, and the interior of a single air-rib arch basic unit Air pressure withstands dangerous values, etc.

[0052] After calcu...

Embodiment 2

[0078] Compared with the above embodiment, in this embodiment, after the thickness of the ice shell reaches the preset value, it is judged whether the number of the ice shell needs to be increased; if the number of the ice shell does not need to be increased, the air rib arch group is removed to make the ice shell Buildings; if the number of ice shells needs to be increased, remove the air-rib arch group and complete the first construction; then use the air-rib arch group for the first construction as a unit mold, based on the ice shell obtained in the first construction, Use at least one method of juxtaposition, rotation, and symmetry for form-finding and construction until it is no longer necessary to add ice shells, remove air rib arch groups, and finally make ice shell buildings. The use of air-rib arch groups for wheel construction can effectively save the materials used to make the basic units of air-rib arches.

[0079] In this embodiment, the added ice shell is carried...

Embodiment 3

[0081] Compared with the above-mentioned embodiment, in this embodiment, after the removal of the air-rib arch group is completed, the internal space of the ice shell is constructed, which mainly includes internal ice engineering construction, ice sculpture carving, lamp arrangement, equipment connection, etc., so that the final Realize the production of ice shell buildings.

[0082] In this embodiment, when the number of ice shells needs to be increased, in the subsequent ice shell manufacturing process, construction can be carried out on the inner space of the ice shells that have already been made, so as to save the manufacturing time of the ice shell buildings as a whole.

Abstract

The invention provides a method for shape-finding and constructing of an air-rib-type ice shell building. The method comprises the steps: building data of the ice shell building are calculated, and aplurality of air rib arch basic units are manufactured through the obtained building data; the multiple air rib arch basic units are inflated for the first time, and the multiple air rib arch basic units inflated for the first time are connected in parallel to form an air rib arch set; the air rib arch set is subjected to foundation fixing, and after foundation fixing completed, the multiple air rib arch basic units in the air rib arch set are synchronously inflated for the second time; after second-time inflating is completed, an ice and snow composite material is sprayed on the outer surfaceof the air rib arch set to form an ice shell; and after the thickness of the ice shell reaches a preset value, the inflatable rib arch set is removed, and the ice shell building is manufactured. Themultiple air rib arch basic units can be synchronously inflated, and thus the manufacturing time of the ice shell building is shortened; and the air rib arch set formed by the multiple air rib arch basic units which are connected in parallel can be subjected to foundation fixing, and thus shape-finding of the air rib arch set is convenient.

Description

technical field [0001] The invention relates to the field of ice building manufacture, in particular to an air-ribbed ice shell building form-finding and building method. Background technique [0002] When making ice buildings, there are two traditional construction methods. The first is to build by stacking ice bricks; the second is to use airbags as a shape-finding and load-carrying template, which is frozen by spraying ice and snow materials. Among them, the second method is widely used in the construction of long-span ice shell buildings. Most of them use a large airbag as a form-finding and load-bearing template. It is difficult to observe when inflated, the foundation is well anchored, and the interior and exterior of the ice shell cannot be constructed at the same time. Contents of the invention [0003] In view of this, the present invention aims to propose a form-finding and construction method for an air-ribbed ice-shell building, which can at least solve one of...
