Heat insulation broken bridge building block for exterior enclosure wall beams and columns and construction method thereof

Abstract

The invention discloses a heat insulation broken bridge building block for exterior enclosure wall beams and columns. The heat insulation broken bridge building block comprises two parts including a U-shaped brick and a heat insulation block, wherein the U-shaped brick is formed by side walls at the two sides and a bottom wall connected with the side walls at the two sides; the heat insulation block is arranged in the middle part of the bottom wall of the U-shaped brick; casting cavities are formed between the two sides of the heat insulation block and the side walls of the U-shaped brick; pulling connection bolts penetrating through the heat insulation block are connected onto the heat insulation block in a penetrating way; and the two ends of the pulling connection bolts are respectivelypositioned in the casting cavities at the two sides. Meanwhile, the invention also discloses a method for performing outer wall ring beam and hole opening construction by using the heat insulation broken bridge building block. When the heat insulation broken bridge building block is used for exterior wall beam and column construction, a support formwork is not needed; a secondary chiseling work procedure possibly generating mold expansion during the casting is avoided; a secondary heat insulation plate bonding process is avoided; a plastering process outside an externally bonded heat insulation plate is avoided; a joint seam treatment process due to inconsistent adjacent materials and plastering posttreatment outside the externally bonded heat insulation plate and other processes are avoided; and the practical values are inestimable.

Description

technical field [0001] The invention relates to a building block for an outer protective wall and its construction, in particular to a heat-insulating broken bridge block for an outer protective wall beam and column and a construction method. Background technique [0002] In the implementation of increasingly demanding energy-saving standards nowadays, the guarantee of the overall thermal insulation performance of the wall is becoming more and more important. Sandwich insulation blocks can ensure the thermal insulation performance of the wall, but for the wall ring beam and the hole lintel, the bottom of the hole and the structural column, there has always been a thermal bridge, so far, it has not been seen. ideal solution. The "U"-shaped bricks for lintels in the traditional construction form have the convenience of ring beams and lintels without formwork, but they do not have heat insulation performance, and their usability is very narrow and poor. There is also a form o...

Problems solved by technology

[0003] One of the purposes of the present invention is to provide heat-insulating broken bridge blocks suitable for the outer wall ring beam or the lintel at the opening and the structural column, so as to solve the problem of the existing outer wall ring beam, the hole lintel, and the bottom of the hole. Blocks for cast-in-place capping and structural columns do not have thermal insulation performance or are prone to the problem of "going into the air" during construction and use

At the same time, another object of the present invention is to provide a construction method for using the heat-insulating broken bridge block to realize the non-thermal bridge external wall ring beam and the non-thermal bridge external wall opening, so as to solve the problem of external wall beams, external wall beams, There is a thermal bridge in the column and the subsequent processing of the thermal bridge is complicated.
