Embodiment 1

[0019] (1) A plurality of spaced diaphragms 2-1 are installed in the steel column 1-1 to form a plurality of compartments, and flow holes 4-1 are opened on each of the diaphragms; (2) through each A pouring hole 3-1 with a diameter of 4 cm on the side wall of the compartment pours the sand aerated thermal insulation material into the steel column, and the sand aerated thermal insulation material poured into the steel column passes through the middle flow hole on the diaphragm 2-1 4-1 and 8 side flow holes for reflow; the hole diameter of the middle flow hole is 18 cm, and the hole diameter of each side flow hole is 4 cm; The insulation material is used until the insulation material expands to fill each compartment of the steel column beam. After the strength and volume of the poured insulation material reach the specified level, it is hoisted for steel column installation in the steel structure.

[0020] After use: there is no cold bridge problem in the box-shaped steel column...

Embodiment 2

[0022] (1) install a plurality of transverse diaphragms 2-2 arranged at intervals in the steel beam 1-2 to form a plurality of compartments, and open flow holes 4-2 on each of the transverse diaphragms; (2) through each A filling hole 3-2 with a diameter of 8 cm on the side wall of a compartment (that is, the side wall of the steel column beam) pours the sand aerated thermal insulation material into the steel column beam, and the sand aerated thermal insulation material poured into the steel column beam passes through The middle flow hole 4-2 on the diaphragm 2-2 reflows; and the 6 side flow holes reflow; the hole diameter of the middle flow hole is 25 cm, and the hole diameter of each side flow hole is 6 cm; (3) After filling the sand-entrained thermal insulation material, maintain the thermal insulation material until the thermal insulation material expands to fill each compartment of the steel column beam. After the strength and volume of the perfused thermal insulation mate...

Embodiment 3

[0025] (1) install a plurality of transverse diaphragms 2-2 arranged at intervals in the steel beam 1-2 to form a plurality of compartments, and open flow holes 4-2 on each of the transverse diaphragms; (2) through each A pouring hole 3-2 with a diameter of 6 cm on the side wall of a compartment (that is, the side wall of the steel column beam) pours the sand aerated thermal insulation material into the steel column beam, and the sand aerated thermal insulation material poured into the steel column beam passes through The middle flow hole 4-2 on the diaphragm 2-2 reflows; and the 6 side flow holes reflow; the hole diameter of the middle flow hole is 22 cm, and the hole diameter of each side flow hole is 5 cm; (3) After filling the sand-entrained thermal insulation material, maintain the thermal insulation material until the thermal insulation material expands to fill each compartment of the steel column beam. After the strength and volume of the perfused thermal insulation mate...

Abstract

The invention discloses a construction method of pouring a sand-aerated heat-insulating material into a steel-structure box type column-beam, comprising the following steps: (1) installing a plurality of diaphragm plates arranged at intervals in the steel column-beam and forming a plurality of separating boxes, wherein a middle flow hole is arranged in the middle of each diaphragm plate; (2) pouring the sand-aerated heat-insulating material into the steel column-beam through pour holes on side walls of the diaphragm plates, wherein the sand-aerated heat-insulating material poured into the steel column-beam flows again through the flow holes on the diaphragm plates; and (3) after the sand-aerated heat-insulating material is poured, maintaining the heat-insulating material till the heat-insulating material is expanded to fill the separating boxes of the steel column-beam and after the strength and the volume of the poured heat-insulating material are up to a standard, hoisting for the installation of the steel-structure steel column-beam. By adopting the method disclosed by the invention, the problem that cold bridge generates at local part of the steel-structure box type column-beam is solved.

Description

technical field [0001] The invention relates to the field of building heat preservation and energy saving, in particular to a construction method for pouring sand aerated heat preservation materials into steel structure box-shaped column beams. Background technique [0002] In recent years, with the continuous deepening of my country's building energy-saving work and the continuous improvement of energy-saving standards, many new energy-saving technologies and materials have been introduced and developed, and their use has been vigorously promoted in buildings. How to adopt new technologies and materials to provide residents with safe, comfortable, economical and functional buildings has become an urgent task for the real estate industry. Steel structure buildings are suitable for mass production in factories and have a high degree of industrialization and commercialization. They can integrate design, production, construction, and installation to improve the level of industr...
