Beam string type foundation pit steel trestle
The invention relates to a beam string structure type foundation pit steel trestle which comprises a stand column supporting system, a beam string structure system and a bridge deck system, the stand column supporting system comprises stand columns, stand column piles and support connecting pieces, the stand columns are provided with inter-column supporting mechanisms, and the inter-column supporting mechanisms comprise horizontal supports and diagonal bracings; the beam string structure system comprises an upper chord pressing rod, a steel web member, a steel pull rod, a connecting pin and an anchoring box, the upper chord pressing rod is provided with an outwards-extending end plate, the bridge deck system comprises a bearing beam, a distribution beam, a bridge deck slab and a protective handrail, the bearing beam is provided with a head plate b and assembled on the upper chord pressing rod, the distribution beam is assembled on the bearing beam, and the bridge deck slab is assembled on the distribution beam. Pattern anti-skid steel plates are welded and laid on the bridge deck slab; prestress is applied to the steel pull rods in the beam string structure, so that a main stress component of the steel trestle becomes a bending component, and the steel trestle has the advantages of being high in bearing capacity, small in deformation and high in structural stability.
本发明涉及一种张弦梁式基坑钢栈桥，包括立柱支撑系统、张弦梁系统以及桥面系统，立柱支撑系统包括立柱、立柱桩以及支座连接件，立柱设置有柱间支撑机构，柱间支撑机构包括水平撑以及剪刀撑，张弦梁系统包括上弦压杆、钢腹杆、钢拉杆、连接销以及锚固箱，上弦压杆设有外伸端板，桥面系统包括承重梁、分配梁、桥面板以及防护栏杆，承重梁设有b封头板，承重梁装配于上弦压杆，分配梁装配于承重梁，桥面板装配于分配梁，桥面板焊接铺设有花纹防滑钢板；本发明通过对张弦梁中的钢拉杆施加预应力，使得钢栈桥的主要受力构件成为压弯构件，具有承载力高、变形小结构稳定性强的特点。
