Steel bar formwork integrated wall formwork bridge-cut-off opposite-pulling connecting rod piece

Abstract

The invention discloses a steel bar formwork integrated wall formwork bridge-cut-off opposite-pulling connecting rod piece. The steel bar formwork integrated wall formwork bridge-cut-off opposite-pulling connecting rod piece comprises a bridge-cut-off connecting piece, a long metal screw rod, a second metal screw rod, gaskets, engineering plastics, structural adhesives, a long metal screw rod nut,a second metal screw rod nut, an air layer, a hollow slurry-guiding and measuring cavity, a flexible sampling probe, sampling grooves and an unpackaged RFID anti-metal chip. According to the steel bar formwork integrated wall formwork bridge-cut-off opposite-pulling connecting rod piece, a traditional metal connecting rod piece is subjected to bridge-cut-off treatment, so that the heat transfer efficiency of the metal rod piece is lowered, the thermal performance is increased, and thus the thermal bridge phenomenon is avoided; and the connecting rod piece is a screw-in connecting rod piece, the main structure of the middle bridge-cut-off connecting piece is the engineering plastics, and the metal screw rods are arranged on the two sides. On the basis of ensuring the use function of the connecting rod piece, the thermal bridge effect is greatly reduced due to the adoption of the engineering plastics in the middle section.

Description

technical field [0001] The invention relates to a pair-tension connecting rod, in particular to a reinforced-formwork-integrated wall formwork broken-bridge opposite-tension connecting rod, which belongs to the technical field of construction applications. Background technique [0002] Prefabricated concrete technology refers to the technology of pouring and curing concrete components in the factory, and then designing and constructing concrete structure buildings through on-site assembly. Compared with traditional cast-in-place buildings, prefabricated buildings have the advantages of high industrialization, easy construction quality assurance, short construction period, high economic benefits, and little impact on climate, and there is no water consumption, energy consumption, and material waste caused by on-site construction. , waste discharge and other issues. In recent years, prefabricated buildings have been strongly supported by national policies because of their uni...

Problems solved by technology

Since the thermal conductivity of conventional connecting rods is much greater than that of the surrounding walls, the connecting rods are serious "thermal bridge areas", which will cause a series of serious problems: serious heat loss, large temperature changes on the wall surface; wall surface Condensation, the walls in cold regions are prone to condensation, frost heaving, and freezing and thawing

However, the connection between the tension connecting rod and the formwork on both sides of the wall needs to penetrate the entire wall (including the insulation layer inside the wall), which will cause serious thermal bridge phenomenon
