Description

Adjustable scaffold base

Technical Field

The utility model relates to a building engineering field, in particular to scaffold frame base with adjustable.

Background

The scaffold is various supports which are erected for workers to operate and solve vertical and horizontal transportation on a construction site of the building engineering, and is an indispensable temporary facility on the construction site. Scaffold base is often needed to use in the installation use process.

Most of existing scaffold bases are vertically welded with supporting vertical rods and base plates, and the angle of the existing scaffold bases cannot be adjusted. However, it is often necessary to provide the scaffold at a chamfered portion, a tucked corner portion, or an inclined ground surface in a construction site. Because the scaffold base is the structure of fixed connection formula, place when the inclined plane, in order to keep the scaffold montant to keep vertical, often there is the space between base and the inclined plane, can not laminate completely, and is very unstable during the use. To address this problem, wooden wedges are typically placed under the scaffolding base to fill it to keep the scaffolding base level. However, the size of the wood wedge is often inconsistent with the included angle between the scaffold base and the inclined plane, so that the filling cannot be dense; and the wood wedge contacted with the inclined surface is easy to slip or fall off, so that the base of the scaffold is eccentrically pressed, and the scaffold collapses to cause serious accidents.

However, most of the existing adjustable scaffold bases on the market are complex in structure, more in parts, more in processing technology and installation steps and inconvenient to use.

SUMMERY OF THE UTILITY MODEL

The small holes in the two supporting legs are symmetrically arranged, so that the rotating shaft and the supporting legs can be connected into a right angle, the screw is perpendicularly connected with the rotating shaft, and when the screw keeps a vertical direction, the supporting legs can rotate at a large angle, so that the supporting legs can be applied to inclined planes with different inclination angles.

In some embodiments, the shaft is a high-strength bolt. From this, can guarantee scaffold frame base's bearing capacity and stability.

In some embodiments, one end of the screw rod is provided with a through hole which can be sleeved on the rotating shaft. From this, the screw rod cup joints with the pivot through the through-hole of one end, makes things convenient for the rotation of screw rod to the screw rod is difficult for droing, and stable in structure is safe.

In some embodiments, the adjustable scaffold base further comprises a support base, and the support legs are fixed on the support base. Therefore, the supporting legs are fixed on the supporting seat, the supporting legs can be prevented from moving randomly, and the stability of the device is enhanced. During construction, the supporting seat is in contact with the ground or the inclined plane, so that the contact area can be increased, and the scaffold device is more stable after being installed.

In some embodiments, the support base is a plate-like structure. From this, the supporting seat can laminate with ground or inclined plane, and the scaffold frame base forms the face contact with ground or inclined plane, and the whole atress of scaffold frame is stable, is difficult for collapsing.

In some embodiments, the adjustable scaffold base further comprises a support plate, and the support plate is sleeved on the screw rod. The one end of screw rod is connected with the scaffold frame montant, cup joints the position that the scaffold frame montant can be adjusted to the layer board on the screw rod.

In some embodiments, the support plate is in threaded connection with a screw, the screw is provided with an external thread, and the support plate is provided with an internal thread. From this, the layer board is comparatively fixed with being connected of screw to the position of layer board is controlled easily, can make things convenient for the regulation to scaffold frame montant.
