YANG XIKUI / ZHANG BAOSHUAN / HAO ZENGHUI / MA JIAAN

The invention discloses a modular unit combined type steel foundation and an installation method thereof, and relates to the technical field of iron tower foundation installation. Comprising a plurality of rectangular steel frames, a plurality of cross-shaped connecting plates, a plurality of triangular steel frames and a plurality of connecting plates. The rectangular steel frame is formed by welding four L-shaped steel plates; three bolt holes are uniformly formed in the upper part and the lower part of the vertical edge of the rectangular steel frame; bolt holes I corresponding to the bolt holes in the vertical sides of the rectangular steel frame are formed in four plates of the cross-shaped connecting plate; the two rectangular steel frames can be connected together through the cross-shaped connecting plate by using bolts; the vertical edges, perpendicular to the ground, of the two triangular steel frames can be connected to the cross-shaped connecting plate through bolts, and the front ends of the straight edges on the ground can be connected together through the connecting plate. The multiple rectangular steel frames can be connected and fixed through the cross-shaped connecting plates, mounting and dismounting are convenient, the rectangular steel frames are provided with ribs, deformation is prevented, certain supporting force is provided for bearing the iron tower, the fixing ribs are fixed after the three-dimensional rectangular steel frames are formed, and the stability of the device is further guaranteed.

本发明公开了模块化单元组合式钢制基础及其安装方法，涉及铁塔基础安装技术领域。包括多个矩形钢架、多个十字型连接板、多个三角形钢架和多个连接板；矩形钢架由四根L型钢板焊接而成；矩形钢架竖边的上部和下部均匀开设有三个螺栓孔；十字型连接板四个板上均开设有与矩形钢架竖边螺栓孔对应的螺栓孔一；两个矩形钢架可以使用螺栓通过十字型连接板连接在一起；两个三角形钢架垂直地面的竖边可以通过螺栓连接在十字型连接板上，地面上直边前端可通过连接板连接在一起。本发明申请中多个矩形钢架之间可以通过十字型连接板连接固定，方便安装拆卸，且矩形钢架设有肋，防止变形，为承载铁塔提供了一定的支持力，且构成立体矩形钢架后固定了固定肋，进一步保证了装置的稳定性。
