The utility model provides a scaffold for building construction, which is shown in fig. 1 to 3 and comprises the following components: a column module 1, a sliding module 2 and a diagonal brace 3 which are arranged in pairs,

in this embodiment, taking two sets of upright post modules 1 as an example, two columns (the columns in fig. 1 and fig. 2 are in a front-back overlapping state) are arranged in each upright post module 1, and in order to better illustrate the technical scheme of the present utility model, the following description refers to the state shown in fig. 1 and fig. 2, the top end of each upright post module 1 is fixedly provided with a first support lug, the first support lugs are respectively connected with a cross rod 4 capable of rotating up and down through a pin shaft, and the free ends of the two cross rods 4 opposite to each other in left and right are rotationally connected through a pin shaft;

each sliding module 2 is vertically and movably connected to the corresponding upright column module 1, specifically, taking a square sliding module 2 as an example, a vertically through channel is arranged on the sliding module 2, the sliding module 2 is sleeved on the upright column module 1 opposite to the square sliding module 2 by using the channel, and the sliding module 2 is in clearance fit with the channel so that the sliding module 2 can slide up and down along the upright column module 1;

in addition, second support lugs are respectively fixedly arranged on the cross rod 4 and the sliding module 2, one end of each inclined support rod 3 is rotationally connected to the second support lug of the sliding module 2 through a pin shaft, and the other end of each inclined support rod 3 is rotationally connected to the second support lug of the cross rod 4 through a pin shaft.

By adopting the scheme, when the scaffold is folded, the two upright post modules 1 are pushed to move in opposite directions, namely the two cross bars 4 can be pushed to arch upwards by the diagonal brace 3, so that the scaffold is folded, and in the process, the sliding module 2 can move relative to the upright post modules 1, so that the movement interference in the folding process is avoided; when the scaffold is used, the inclined stay bars 3, the cross bars 4 and the upright post modules 1 enclose a triangular framework, so that the gravity of workers can be transferred to the upright post modules 1 and the inclined stay bars 3, and the stability of the scaffold is enhanced.

In another embodiment of the present utility model, as shown in fig. 2, a U-shaped lifting lug (not shown in the figure) is provided on the sliding module 2 on the left side, and the present utility model further includes a connecting piece made of a flexible rope 5, in this embodiment, a steel wire rope is taken as an example, the right end of the steel wire rope is fixedly provided on the sliding module 2 on the right side, and the left end of the steel wire rope is fixedly provided with a hook, where the hook is hung on the lifting lug.

When a person stands at the top end of the scaffold, the two upright post modules 1 are in a trend of deviating from the external tension, the two upright post modules 1 can be tensioned by the steel wire ropes, and the steel wire ropes and the two diagonal braces 3 form a triangular framework, so that the stability of the scaffold is further enhanced; secondly, when the scaffold is folded, the steel wire rope can deform, and motion interference cannot be generated in the folding process; in addition, wire rope passes through the couple and is connected with stand module 1, the dismouting of being convenient for.

Further, the rolling shaft is installed on the sliding module 2 deviating from the hook through a bearing, one end of the rolling shaft is fixedly connected with one end of the steel wire rope, the rocker arm 10 coaxial with the rolling shaft is further fixedly arranged at one end of the rolling shaft, when the rolling shaft is folded, the hook is taken down from the upright post module 1, and then an operator rotates the rocker arm 10 to roll the steel wire rope on the rolling shaft, so that the rolling shaft is tidier.
