Building structures with frost protection

Abstract

The invention discloses a building structure with an anti-freezing function. The building structure comprises a heating layer, a high-temperature-resistant insulating medium layer and a photoelectriclayer used for supplying power to the heating layer, which are sequentially arranged from top to bottom. The heating layer comprises a heat transfer layer and a plurality of resistance heating bodiesarranged on the upper surface of the high-temperature-resistant insulating medium layer, and a plurality of mixing bags which are of semicircular hollow structures and correspond to the resistance heating bodies are arranged on the lower surface of the heat transfer layer. The top of each mixing bag is provided with a water bag which is positioned in the heat transfer layer and is in a semi-circular hollow structure, and a leather bag which is of a semicircular hollow structure and is used for storing sodium oxide is arranged in each water bag. A sponge used for sealing the movable hole is arranged in the movable hole, and a sliding cavity communicated with the mixing bag is formed in the bottom of each mixing bag, and a sliding plate which is positioned at the bottom of each mixing bag and can move in a reciprocating mode along the sliding cavity is arranged at the top of the sliding cavity, and a metal sheet which extends out of the sliding cavity and can abut against the resistanceheating body is arranged at the bottom of the sliding plate. The top of the sliding plate is provided with a pressure spring fixedly connected with the bottom of the sponge. The anti-freezing device has an anti-freezing function.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a building structure with antifreeze function. Background technique [0002] Conventional viaduct pavement structure generally adopts the structure of 9cm asphalt concrete plus 8cm~9cm concrete. When encountering bad weather such as sudden drop in temperature, snow and ice, the bridge deck is prone to icicles, and the icicles will make the driving condition of the bridge deck poor, easily cause traffic accidents, and seriously endanger driving safety. At present, there are usually two methods for dealing with icing on bridge decks: one is to manually remove icing, which has low efficiency and poor working conditions, and has a great impact on urban traffic; However, this salt-containing deicing agent will seriously corrode the pavement structure, greatly increasing the possibility of early failure, resulting in continuous increase in road maintenance costs.
