The invention discloses a telescopic floor supporting truss, and belongs to the technical field of construction methods and measures of constructional engineering. The supporting truss is composed of an upper chord middle section rectangular tube, an inverted triangular support, a lower chord tightener and a truss support. The inverted triangular frame is formed by welding rectangular pipes, the structure is more stable, the size of an inner hole of the upper chord rectangular pipe of the inverted triangular frame is consistent with that of an upper chord middle section square pipe, connecting holes are drilled in the upper chord middle section rectangular pipe every certain distance, and the upper chord middle section rectangular pipe penetrates into one end, with the connecting holes, of the upper chord rectangular pipe of the inverted triangular frame and is fixed through bolts. And the intersection point of the lower web members of the inverted tripod is connected with a lower chord tightener hook to realize truss arching. The truss support is connected with the web perforated steel beam through a bolt, the truss support is connected with the bolt through a welding nut, and the upper portion of the bolt is embedded into the groove to jack up and support the truss. Bolts can adjust the height of the supporting truss through nuts. The adjustable distance of the tops of the bolts on the two sides in the groove of the connecting piece is larger than the drilling distance of the rectangular pipe in the middle section of the upper chord and the design of the lower chord tightener enables the supporting truss to stretch out and draw back in any size within a certain range.
发明公开了一种可伸缩楼板支撑桁架,属于建筑工程的施工方法与措施技术领域。该支撑桁架由上弦中间段矩管、倒三角架、下弦紧线器和桁架支座组成。倒三角架通过矩管焊接而成，结构更稳定，倒三角架上弦杆矩管内孔尺寸与上弦中间段方管一致，上弦中间段矩管每个一段距离钻连接孔，上弦中间段矩管穿入倒三角架上弦杆矩管带连接孔一端，通过插销固定。倒三角架下部腹杆交点与下弦紧线器吊钩连接，实现桁架起拱。倒三角架另一端焊接凹槽连接件，桁架支座通过螺栓与腹板开孔钢梁连接，桁架支座焊接螺母连接螺栓，螺栓上部嵌入凹槽顶起支撑桁架。螺栓通过螺母可以调节支撑桁架高度。通过两侧螺栓顶部在连接件凹槽内可调距离大于上弦中间段矩管钻孔距离和下弦紧线器设计使支撑桁架在一定范围内实现任意尺寸伸缩。
