Building assembled with prefabricated space frame substructures and construction method thereof

Abstract

The invention discloses a building assembled with prefabricated space frame substructures and a construction method thereof. The building comprises two main classes of prefabricated substructures, namely prefabricated space frame substructures and prefabricated beam substructures. A process of connecting the two classes of prefabricated substructures is provided. The prefabricated space frame substructures have different forms for the roof, standard layer, inside, lateral sides and corners of a house. Vertical connecting joints can be staggered by the aid of the single-layer and double-layer prefabricated space frame substructures. Horizontal connecting joints can be staggered and crossed by the aid of the single-span and double-span prefabricated space frame substructures. The prefabricated beam substructures are connected with the frame substructures in the horizontal direction and are provided with protrusions matching with notches of cantilever short beams on columns of the prefabricated space frame substructures. By providing the novel pre-assembly way of the framed house based on the fact that the current transporting and lifting level is increased greatly, the design and production flow is simplified and construction speed is increased. Integrity and seismic performance of the house built by the construction method are fine.

Description

technical field [0001] The patent of the present invention relates to the technical field of construction of prefabricated concrete houses in civil engineering, specifically a reinforced concrete house with frame structure assembled by prefabricated substructures and its assembled construction method, and particularly relates to the type, style, Assembly method and connection process. Background technique [0002] The beam-column components of traditional reinforced concrete frame structure buildings are usually casted after the formwork is set up on the construction site. The components are reliable in connection, have good integrity and seismic performance, but the construction period is long and the management is complicated. The prefabricated assembly of frame structure buildings represents an advanced development direction. [0003] At present, my country's prefabricated frame buildings are often prefabricated by small and medium-sized component factories, such as pref...

Problems solved by technology

Both have their own advantages and disadvantages. In fact, the wet method is still a continuation of the cast-in-place process. On the one hand, it can naturally achieve effective connection, but on the other hand, it reduces the construction efficiency to a certain extent. It is difficult to guarantee the construction quality of joints due to technical requirements, and a large number of supports still need to be used during construction. These shortcomings are not expected by the industrialization of construction.

In this sense, compared with the wet method, the dry method with a built-in steel plate has more advantages, but the dry method is often inferior to the wet method in terms of integrity and reliability
