Pulling-resistant toggle pin for anchoring heat insulation plate on hollow brick wall

Abstract

The invention relates to a pulling-resistant toggle pin for anchoring a heat insulation plate on a hollow brick wall. The pulling-resistant toggle pin for anchoring the heat insulation plate on the hollow brick wall comprises an expanding pipe with a circular disc on the tail part and a bulge section on the front middle section, wherein an expanding plug capable of being clamped to an inner wall of a cavity of a hollow brick is arranged at the front end of the expand pipe; sliding chutes for the expanding plug to slide front and back are formed in two sides of the bulge section; an inner-threaded circular hole is formed in the middle of the expanding plug; raised strips are arranged on two sides of the expanding plug and are matched with the sliding chutes in two sides of the expanding pipe; a metal screw rod is screwed into the expanding pipe; the tail part of the metal screw rod presses the circular disc of the expanding pipe; and the front end of the metal screw rod is screwed intothe expanding plug. The pulling-resistant toggle pin for anchoring the heat insulation plate on the hollow brick wall provided by the invention solves the problem that when the outer wall heat insulation plate is arranged on the hollow brick wall, the effective anchoring length of an outer wall insulation toggle pin is insufficient, so that the aim of anchoring the heat insulation plate on the hollow brick wall body is achieved.

Description

technical field [0001] The invention is applicable to the external insulation board project of the hollow brick exterior wall, and particularly relates to a pullout-resistant bolt used for anchoring the insulation board on the hollow brick wall. Background technique [0002] With the rapid development of my country's construction industry, the requirements for building energy conservation are getting higher and higher, and it is required to carry out energy-saving and thermal insulation design for the exterior walls of buildings in architectural design. Energy-saving insulation generally adopts external wall insulation boards to achieve the purpose of building energy-saving insulation. [0003] The external wall insulation board is fixed to the base wall with external wall insulation bolts, and the types of base wall include reinforced concrete wall, aerated concrete block wall, and hollow brick block wall. The external wall insulation currently used The stud is extruding t...
