[0039] Based on the scaffold bottom support device provided in the second embodiment, its horizontal placement can be well controlled by means of the second spring 19 at the bottom during actual use, but it is still necessary to manually place the bottom plate 1 horizontally at the initial stage of placement. Difficulty is big, and at the same time tools are used to make the position of the bottom plate 1 on the top change all the time when the drilling string 14 is drilled into the ground. With the elastic adjustment of the second spring 19, the bottom plate 1 cannot be corrected. In order to solve this problem, the bottom plate 1 is always in a horizontal state, combined with Figure 6-10 , this kind of scaffolding bottom supporting device also comprises: fixed barrel 4 inside top center is provided with suspension rope 26, and the bottom of suspension rope 26 is provided with heavy hammer 27, and the quality of heavy hammer 27 is far greater than the quality of each componen...

Abstract

The invention belongs to the technical field of supporting, and discloses a scaffold bottom supporting device. The scaffold bottom supporting device comprises a bottom plate, wherein a fixing barrel is arranged at the center of the top of the bottom plate, a lantern ring is arranged on the outer surface of the end, away from the bottom plate, of the fixing barrel, a fixing ring is arranged at the top of the outer surface of the lantern ring, a plurality of first sliding grooves are formed in the top of the fixing barrel in a circumferential array mode, first sliding blocks are slidably connected into the first sliding grooves, a fixing clamp is arranged at the top of the first sliding blocks, a plurality of first springs are evenly arranged on the inner side face of the fixing clamp in a circumferential array mode, a semicircular ring is arranged at the end, away from the fixing clamp, of each first spring, the bottom plate is polygonal, a plurality of supporting columns are arranged on the outer surface of the fixing barrel in a circumferential array mode, the other sides of the supporting columns are fixedly connected with the vertex of the bottom plate, and second sliding grooves are formed in inner cavities of the supporting columns. The scaffold bottom supporting device is more stable, steel pipes of different sizes can be installed, the service life is long, the inclination degree is accurately controlled, and inclination can be adjusted in a self-adaptive mode.

Description

technical field [0001] The invention belongs to the technical field of support, in particular to a scaffold bottom support device. Background technique [0002] Scaffolding is a work platform set up to ensure the smooth progress of each construction process. It can be divided into outer scaffolding and inner scaffolding according to the erection position. It can be divided into wooden scaffolding, bamboo scaffolding and steel pipe scaffolding according to different materials. According to the structure, it can be divided into vertical pole type. Scaffolding, bridge scaffolding, portal scaffolding, suspended scaffolding, hanging scaffolding, pick-up scaffolding and climbing scaffolding, jacking refers to the support used for steel pipes and scaffolding, to adjust the height of scaffolding and pipe racks, balance support Weights and supports that bear the weight of the concrete structure. [0003] The existing support device at the bottom of the scaffold cannot be installed w...
