Novel method for installing prestress connecting piece of concrete heat-insulating sandwich board

Abstract

The invention relates to a novel method for installing a prestress connecting piece of a concrete heat-insulating sandwich board, which comprises the following steps of: connecting an anchoring end socket and a bolt, and pre-burying into a concrete outer blade board; sleeving a casing pipe on the bolt which exposes from the concrete outer blade board, and allowing a cushion block to pass through the bolt and the casing pipe, and jointing the cushion block and the concrete outer blade board; paving an insulating layer; pouring a concrete inner blade plate on the insulating layer and the cushion block, and reserving a groove, so that one end of the bolt passes through the groove of the concrete inner blade plate; and after concrete reaches the anticipated strength, installing a gasket in the groove, and stretching the bolt to be fixed by an anchorage device. By the method, the prestress connecting piece is easy to install, reasonable in structure, low in cost, safe and reliable.

Description

technical field [0001] The invention relates to a method for installing a prestressed connector of a novel concrete insulation sandwich panel used in construction engineering. Background technique [0002] The outer wall panels with thermal insulation properties composed of inner and outer concrete panels and intermediate insulation materials connected by connectors are referred to as concrete insulation sandwich panels; the inner panel is generally called the inner leaf plate, and the outer layer plate is generally called the outer leaf plate. [0003] Concrete thermal insulation sandwich panels are generally used as the outer protective structure of buildings, and have the function of thermal insulation. The inner blades are fixed on the main body of the building, and the outer blades are fixed on the inner blades through connectors. The self-weight of the upper finish, the wind load and earthquake load acting on the outer blades are transmitted to the inner blades through...

AI Technical Summary

Problems solved by technology

[0007] Composite reinforced fiber connectors use non-metallic parts (composite reinforced fibers) in order to avoid structural thermal bridges and solve the anti-corrosion problem of iron parts, and the cost is relatively high; the structure is simple and the bearing capacity of a single piece is low; in order to meet the anchoring requirements of the connectors , the minimum thickness of the inner and outer leaf plates is required to be thicker; it is possible to increase the amount of concrete and increase the cost
