Embedded external-top insulation board fixed connection device

Abstract

The invention discloses an embedded external-top insulation board fixed connection device which is characterized in that the inner end of an embedded pipe has a base, a core pipe connected with the base is arranged in the embedded pipe, wherein an external thread is arranged on the outer wall of the core pipe; an embedded piece is of a flaky shape, and the longitudinal end is connected with the bottom of the embedded pipe; the outer end of a positioning cone is of a conical shape and is positioned outside the embedded pipe; the core pipe is inserted into the inner end of the positioning cone; a cap is arranged at the outer open end of the embedded pipe; a feed pipe is a hollow pipe, and a prism hole is formed at the upper end; an internal thread of the feed pipe matched with the external thread of the core pipe is arranged at the lower part of the prism hole in the feed pipe; a pressure piece is an annular piece; the lower part of the annular inner edge of the pressure piece is connected with a coaxial sleeve; the lower end of the sleeve is connected with an inward annular boss; the annular boss is sleeved outside the core pipe; the feed pipe is arranged in the sleeve; the lower end of the feed pipe is pressed on the annular boss; an annular slot is formed close to the inner-end outer surface of the sleeve; and a seal ring in seal contact with the inner wall of the embedded pipe is sleeved on the annular slot. The connection is firm, and the movable part is easy to disassemble.

Description

Technical field [0001] The invention relates to an appliance used in the installation of a thermal insulation board, in particular to a fixed connection device for a pre-embedded outer top thermal insulation board. Background technique [0002] In the field of construction, thermal insulation panels have been used as energy-saving and environmentally-friendly components. The existing construction technology is to bond expansion nails to make them firmly connected to the building facade. The existing expansion nails have a raised The screw is flat-headed and it is more laborious to insert the insulation board, and it is not easy to align the position of the insulation board after the insertion. The screw extends out of the insulation board and needs to be bent and embedded in the insulation board after fixing to ensure that it does not hinder the later finishing construction and is easy to damage during bending. Insulation board, these problems still need to be solved technically....

AI Technical Summary

Problems solved by technology

[0002] In the field of construction, thermal insulation boards have been used as energy-saving and environmentally friendly components. The existing construction technology is to bond expansion nails to make it firmly connected with the building facade. The existing expansion nails have a vertical structure after fixing the building facade. Screw, the screw has a flat head to penetrate the insulation board. It is laborious, and the position of the insulation board is not easy to align after the insertion. The screw sticks out of the insulation board. Insulation boards, these issues are still to be solved by technology
