An integrated structure and construction method for existing building exterior wall insulation

Abstract

The invention discloses an existing building external wall heat preservation integrated structure. The existing building external wall heat preservation integrated structure comprises an existing wallbody, a heat preservation plate and a face layer, first round holes communicating with one another are formed in the existing wall body, the heat preservation plate and the face layer, and connectionpipes are transversely distributed and arranged in the first round holes. A sealing plate is arranged at one ends of the connection pipes, and a threaded hole is formed in the center of the sealing plate. A second round hole is formed in the position, on the left side of the existing wall body, of the first round hole, the second round hole penetrates through the outer side of the existing wall body and provided with a pipe seat, the pipe seat comprises a bolt and a seat plate, a round hole is formed in the center of the seat plate, and the bolt penetrates through the round hole and welded tothe seat plate. The invention further provides a construction method of the existing building external wall heat preservation integrated structure, the construction method comprises the following steps that drilling is conducted; the connection pipes and the pipe seat are mounted; grouting is conducted; a heat preservation plate is adhered, and a reinforcing steel bar net is strapped; the face layer is smeared and maintained. According to the existing building external wall heat preservation integrated structure and the construction method, integration of heat preservation and structure of anexisting building external wall in different types is achieved, and it is ensured that the life of external heat preservation of the external wall is as long as the structure.

Description

technical field [0001] The invention relates to the field of building technology, in particular to an integrated structure and construction method for existing building exterior wall heat preservation. Background technique [0002] With the development requirements of the national energy-saving policy, the domestic building exterior wall insulation system has developed rapidly. The energy-saving renovation of existing building exterior walls is the focus of energy-saving and emission reduction in my country's current construction industry. The objects of energy-saving renovation of existing building exterior walls are mainly those that have not been done before. Buildings with external wall insulation, and buildings with external wall insulation that have fallen off the external wall insulation; in the past, the conventional external wall insulation method is to directly paste the insulation board on the outside of the wall. This method has the following Problems: short servic...

Problems solved by technology

[0002] With the development requirements of the national energy-saving policy, the domestic building exterior wall insulation system has developed rapidly. The energy-saving renovation of existing building exterior walls is the focus of energy-saving and emission reduction in my country's current construction industry. The objects of energy-saving renovation of existing building exterior walls are mainly those that have not been done before. Buildings with external wall insulation, and buildings with external wall insulation that have fallen off the external wall insulation; in the past, the conventional external wall insulation method is to directly paste the insulation board on the outside of the wall. This method has the following Problems: short service life, poor fire performance, and cannot guarantee the safety of pasted bricks; there are also limitations in the method of building exterior wall insulation, which can only be applied to one type of wall, and cannot be applied to all walls at the same time, making The use of external wall thermal insulation is limited; the method for energy-saving renovation of existing building external wall thermal insulation proposed by the present invention can realize the integration of various existing building external wall thermal insulation and structures, ensure the same life span of external wall thermal insulation and structures, and achieve "Building Fire performance required by GB50016 Code for Fire Protection Design
