Light steel keel structure and construction method thereof

SHAN BINGQUAN

The invention provides a light steel keel structure. The light steel keel structure is arranged at the lower part of a wall top, comprises a main keel, a sub keel, a hanging piece, a side keel and a hanging rod, and is characterized in that the top end of the hanging rod is fixedly connected with the hanging piece, and is vertical to and fixedly connected with the wall top through the hanging piece; the main keel is fixedly connected with the bottom end of the hanging rod through a bracket; the sub keel is fixedly connected with the lower surface of the main keel through the hanging piece arranged on the main keel, is parallel to the ground and is perpendicular to the main keel; the side keel is fixed to the upper half part of the wall through a soft connecting piece; and the two ends of the sub keel are placed on the lower side wall of the side keel and is abutted against the upper side wall of the side keel. The invention also provides a construction method of the light steel keel structure. The construction method is used for installing the light steel keel structure. The light steel keel structure built by using the construction method cannot easily deform or crack under the effects of thermal expansion and cold contraction or external force, and has good corrosion resistance, and the service life of the light steel keel structure is prolonged.

本发明提出一种轻钢龙骨结构，设置于墙顶下部，包括主龙骨、次龙骨、挂件、边龙骨和吊杆，其特征在于，吊杆顶端固定连接有吊挂件，并通过吊挂件与墙顶垂直并固定连接；主龙骨通过支托固定连接于吊杆底端；次龙骨通过设置于主龙骨上的挂件固定连接于主龙骨的下表面，次龙骨平行于地面且与主龙骨垂直；边龙骨通过软连接件固定在墙壁上半部；次龙骨的两端放置于边龙骨的下侧壁上，并顶住边龙骨的上侧壁。本发明还提供一种轻钢龙骨结构施工方法，用于安装上述轻钢龙骨结构。通过该施工方法建造的轻钢龙骨结构，在受到热胀冷缩或外力作用时，不易发生形变和开裂，且具备良好的抗腐蚀性，延长了轻钢龙骨结构的使用寿命。
