Problems solved by technology

[0003] In response to the above shortcomings, many self-insulating blocks have appeared on the market at present, but even if self-insulating blocks are used to build the wall, it still needs to make a moisture-proof layer and an insulating layer at the structural column, which will increase the cost and reduce the cost. Use of space; at the same time, since the structural column needs to be cast in place, the construction period will be significantly extended
[0004] In order to solve the above shortcomings, prefabricated structural columns and thermal insulation structural columns have also been developed. For example, the Chinese patent with the publication number of CN201343823 discloses a structural column for masonry structures and its special prefabricated sections. Although the construction is convenient and reduces The construction period is limited, but the thermal insulation and moisture-proof effects of the structural column are not considered; the Chinese patent with the publication number CN201474105U discloses a new type of thermal insulation structural column structure. The cross-section of the structural column is reduced, which is not conducive to earthquake resistance, and the scope of use is limited, and the problems of construction inconvenience have not been solved; the Chinese patent with the publication number CN201915525U discloses a new type of masonry structure corner structural column, which is built by thermal insulation. One end of the block is extended to form a right-angled structure to form a structural column cavity, and an insulation layer is set in the right-angled structure
This kind of structural column is filled with concrete in the cavity, and the construction period is long, and there is a "cold bridge" when the two thermal insulation blocks overlap each other, which reduces the thermal insulation effect

Abstract

The invention relates to a precast segment, a precast segment assembly and an anti-seismic self-insulating constructional column. As one or more first through grooves communicating the two bottom surfaces of a building block, one or more second through grooves penetrating through a convex corner are formed in the precast segment, and the first through grooves and the second through grooves are filled with insulating bags made of insulating materials, the first through grooves and the second through grooves are vertically and horizontally crossed and distributed when the precast segments are stacked layer by layer to form the anti-seismic self-insulating constructional column, so that a cold bridge formed when the constructional columns are placed and overlapped is cut off, as a result, the effects of excellent insulating performance and high intensity are achieved; on the other hand, the raised height of a boss on the upper end surface of each precast segment is larger than the cup depth of each groove, so that the precast segments on the upper layer and on the lower layer can be mutually clamped and not completely stuck during placing; besides, longitudinal bars are equipped in preserved communicated through holes in the upper end surface and the lower end surface, so that the precast segments are integrated to improve the intensity, and the constructional column has excellent anti-seismic effect.

Description

technical field [0001] The invention relates to the field of building energy saving and heat preservation, in particular to a prefabricated section for a masonry structure, a prefabricated section assembly and an anti-seismic self-insulation structural column. Background technique [0002] At present, most of the houses in urban areas and rural areas in my country still use masonry structures. With the rapid development of the construction industry, the requirements for building materials are also constantly increasing. As far as buildings are concerned, their stability, thermal insulation and waterproofness, and the convenience of the masonry process usually need to be considered. When building a traditional masonry structure, the brick masonry wall is generally built first, and the structural columns are poured after the horse teeth are left. The masonry structure built in this way is difficult in construction and has a long construction period. Another problem is that t...
