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

Embodiment Construction
[0012] Examples of the present invention Figures 1 to 3 As shown, the fixed connection device of the pre-buried outer roof type insulation board is provided with a buried pipe 1, a buried piece 2, a positioning cone 3, a feeding pipe 18 and a pressing piece 4. The side wall of the buried pipe is cylindrical, and the buried pipe The outer end is open, the inner end of the buried pipe has a bottom 5, and a core pipe 6 connected to the bottom is arranged inside the buried pipe. The outer wall of the core pipe is provided with an external thread 7, and the embedded sheet is sheet-shaped, and one longitudinal end is connected to the bottom of the buried pipe. There are gaps 8 and holes 9 that run through the sheet body. The gaps or holes gradually increase from one end of the buried pipe to the opening surface of the other end. The outer end has greater strength, and the rear end generates a large pulling force; The outer end of the cone is located outside the buried pipe, the inn...

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 a tool used in the installation of a thermal insulation board, in particular to a pre-embedded outer top type thermal insulation board fixing and connecting device. Background technique [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 problems still need to be solved by technology. Contents of the invention [0003] In order to solve the above problems, the present invention provides a fixed connecti...
