Description

Yurt device with integral folding grid structure

Technical Field

The invention relates to a yurt structure, in particular to a yurt device with an integrally folded grid structure.

Background

The main body structure of the prior mongolian yurt is a wood frame structure and comprises three parts, namely a brain (namely a skylight), wu Ni (namely rafters) and hana (namely an enclosing wall). The hana part of the traditional Mongolian yurt is a double-layer cross-folded wood net frame and is hinged by a single-point leather rope. The brain is a round wood frame with small holes, and the hole groove is used for fixing Wu Ni. Each of the hana, the tani and the hana, and the hana are connected by horsehair ropes by using a specific binding method. The building sequence of the mongolian yurt is from inside to outside. Firstly, erecting the hana, lifting the mantle at the central position by one person, inserting one end of Wu Ni into the mantle around the center by the other person, connecting the other end of the mantle with the hana, and completing the whole connection of the components, at the moment, hanging a sand bag by the mantle to assist in central positioning, and binding the hana by the periphery by using a rope belt so as to limit the hana to continue to be unfolded. Finally, the thatch mat is wrapped layer by layer in a specific sequence. When the tarpaulin is covered completely, the sand bag can be taken down, and the mongolian yurt forms a stable structural system.

The yurt can be conveniently transported and quickly built and removed, and the halna adopts a scissor-type expandable structure which can be opened and closed. The shear type expandable structure is a generic term for spatial structures based on shear type structural units. The deformable nature of the scissor type construction unit imparts the ability to unfold and fold the scissor type deployable structure. The basic construction of the scissor unit is two articulated rods, which can be divided into a translation type (Translational unit), a Polar angle type (Polar unit) and a folded rod type (folded unit) according to the positions of the hinge points and the geometric shapes of the rods. The two rods of the translation type scissor unit are equal-length straight rods, the hinge point is at the midpoint of the two rods, the two rods of the polar angle type unit are straight rods, the hinge point deviates from the midpoint of the rods, the two rods of the folding rod type unit are fold line segments, and the hinge point is at the folding position of the rods. All three types of scissor units have one directional degree of freedom, which gives them variable properties. The plurality of scissor units may be articulated to each other and still maintain variable characteristics when certain conditions are met. However, such a combination of units still retains freedom after full deployment, and only additional external constraints are applied to change the mechanism to a stable configuration. Therefore, how to ensure the whole unfolding and folding and the stability of the unfolding state, which is the core problem to be solved when the scissor-type unfolding structure is applied, is ensured.

In the traditional yurt, in order to keep the yurt side wall skeleton-hana of the shear-type expandable structure stable, on one hand, each single of the grid structure is bent, the side wall is a cylindrical surface after expansion, weak locking is realized by means of the interaction of rod pieces, and on the other hand, the outer side of the integral enclosing skeleton is bound by an inner enclosing rope so as to resist the skeleton from being continuously expanded outwards. However, the traditional mongolian yurt takes leather ropes or horsehair ropes as node connecting materials, and does not have the condition of mass production in modern industrialization; meanwhile, the method for binding the fixed nodes is not enough in stability, high in technical requirements on the construction process, high in operation difficulty and often needs digital experienced local talents to finish. In a word, traditional yurt double-deck cross folding type wood net frame needs the on-the-spot amalgamation of binding of multichip hana, and hana still need enclose the constraint of rope after erectting and loading and just can reach the stable state in each direction of scalable structure, and the installation technique degree of difficulty is big, assembly efficiency is low.
