Description

A flexible connection modular building wall

technical field

The utility model relates to the field of modular building walls, in particular to a flexibly connected modular building wall.

Background technique

Modular buildings have the characteristics of quickness and material saving, and have great development space in the construction industry. However, existing modular building wall materials are usually rigidly connected, and it is necessary to significantly increase the amount of steel used to overcome the shedding and cracking caused by vibration (transportation and earthquakes, etc.). The method of combining light steel keel and light wall can effectively overcome the above problems, but it brings problems of cost and wall thickness.

The Chinese invention patent application with the application publication number CN 102277926A (application number 201010197276.5) discloses a building industrialized energy-saving and anti-seismic integral wallboard, which is composed of a corrugated inner keel board and two panels. Set and install energy-saving sound insulation boards to form an integral wall with corrugated cardboard structure. This kind of wall can be used as the interior and exterior walls of industrialized buildings. This kind of wall can be assembled at the construction site of the building wall or directly by the factory. Or the construction site is first assembled into an integral wall module, and then the installation of the wall is completed by hoisting. The wall panel is composed of corrugated inner keel board and two panels, which has the characteristics of energy saving and earthquake resistance. However, the heat storage coefficient of the wall is low, so the indoor temperature is easily fluctuated by ambient temperature changes.

The utility model can meet the energy-saving and anti-seismic requirements of the enclosure structure of the box-type modular building by designing a flexible-connected high-heat-storage wall body.

The existing light-weight wall materials are basically rigidly connected, and the surrounding walls and the columns and beams are reinforced with steel bars to form a solid whole. However, strong stress will be generated under the action of horizontal vibration force, which will damage the walls and even the columns. The existing improvement method is to use light steel keels to connect the columns and beams, and light wall materials to be fixed to the light steel keels. This method increases the cost of the wall and significantly increases the thickness of the wall.

Utility model content
