Chord system arched beam structure for foundation pit supporting
The invention discloses a string system arched beam structure for supporting a foundation pit. The invention relates to a string system arched beam structure which is mainly used for deformation control of a foundation pit engineering enclosure structure, and relates to the field of foundation pit supporting, and the string system arched beam structure comprises a similar triangular component, an arched component, a support, a lower string, a reinforcing component, a connecting component, a reinforcing plate and a stress adjusting device. The similar triangular component is connected with the arch-shaped component through the bolts and the reinforcing plates, the similar triangular component and the arch-shaped component are connected with the support through the bolts, and the lower chord is fixed on the support through the bolts or the anchorage devices. The arch-shaped component is formed by double-spliced H-shaped steel in a hot bending mode. And stiffening rib plates are arranged on the web plate of the similar triangular component and in the support. According to the string system arched beam structure, by means of the arch structure, the vertical soil pressure on the outer side of the structure is converted into the axial force in the arch structure, the axial force is transmitted to the supports and the enclosing purlins through the supports, and the structure and stress both meet the requirements of the existing steel structure design standard. Under the safe and economical conditions, deformation of the enclosure structure is controlled, and therefore the effect of increasing the supporting distance is achieved.
一种用于基坑支护的弦系拱形梁结构。本发明涉及一种弦系拱形梁结构，主要用于基坑工程围护结构变形控制，涉及基坑支护领域，该弦系拱形梁包括类三角构件，拱形构件、支座及下弦、加强构件、连接构件、加强板、应力调节装置。类三角构件通过螺栓及加强板与拱形构件连接，类三角构件、拱形构件通过螺栓与支座连接，下弦用螺栓或者锚具固定在支座上。拱形构件是由双拼H型钢热弯而成。类三角构件腹板上及支座内设有加劲肋板。该弦系拱形梁结构通过利用拱结构，把结构外侧竖向土压力转换成拱结构内部轴力，并通过支座传递给支撑和围檩，构造和受力均满足现行《钢结构设计标准》的要求。在安全、经济的条件下，控制围护结构变形，从而达到增大支撑间距的效果。
