Embedded reinforcing component for polyurethane cold storage board core material

Abstract

The invention relates to an embedded reinforcing component for a polyurethane cold storage board core material. The reinforcing component is used for fixedly connecting a cold storage board with a steel beam. The cold storage board comprises a polyurethane sandwich board body and metal panels arranged on the two sides of the polyurethane sandwich board body. The reinforcing component comprises a plurality of anti-drawing units embedded in the polyurethane sandwich board body in parallel, and elastic pressing reinforcing units arranged on the metal panels and fixedly connected with the anti-drawing units. The anti-drawing units are fixedly connected with the multiple pairs of elastic pressing reinforcing units through connecting elements. Each pair of elastic pressing reinforcing units forms a pair of pressing-connection joints for assembling the steel beam. The steel beam is fixedly connected with the cold storage board through the elastic pressing reinforcing units. Compared with the prior art, the embedded reinforcing component is simple in overall structure and convenient and fast to install, the construction cycle can be effectively shortened, and a traditional fixing mode that nylon staples penetrate through the whole piece of cold storage board and the steel beam is omitted, so that the overall heat preservation performance of the cold storage board is effectively enhanced, and the embedded reinforcing component is low in economic cost and can be applied and popularized advantageously.

Description

technical field [0001] The invention belongs to the technical field of boards for cold storage, and relates to a pre-embedded reinforcement member, in particular to a pre-embedded reinforcement member used for the core material of a polyurethane cold storage board. Background technique [0002] At present, cold storage sandwich panels have become the mainstream panels used in cold storage buildings, which are energy-saving and heat-insulating, and easy to install. The existing cold storage panels mainly use polyurethane foam sandwich panels as the insulation layer. Since the thermal conductivity of polyurethane foam is about 0.025W / (m·K), in order to achieve the cold storage effect, a thicker polyurethane insulation layer is often required, which makes The installation requirements of the cold storage board are relatively high. Existing cold storage panels generally use nylon nails, which are installed through holes in the installation. However, the use of nylon nails with ...

AI Technical Summary

Problems solved by technology

Existing cold storage panels generally use nylon nails, which are installed through holes in the installation. However, the use of nylon nails with double penetration has a great impact on the overall thermal insulation performance of the cold storage panels, especially in low-temperature freezers. The nylon nail connection method has a greater influence on the thermal insulation performance of the 200mm thick cold storage panel

Therefore, it is necessary to study a reinforcement member that can effectively solve technical problems such as the reduction of the insulation performance of cold storage panels due to the use of nylon nails.
