Scaffolding Solutions

Scaffolding refers to various supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. Mainly for construction personnel to operate up and down or to protect the outer safety net and install components at high altitude. There are many types of scaffolding. Mainly include: working scaffolding system, protection scaffolding system and load bearing and support scaffolding system.


According to the support method of the scaffold, there are also floor-standing scaffolding, which also named scaffolding tower, overhanging scaffolding and suspended scaffolding. The overall climbing scaffold (referred to as "climbing scaffolding") is now mostly operated as an independent system in the construction industry.
The scaffolding system is one of the most important links and systems for safe construction in construction engineering. We call it the safe guarding system. Sampmax Construction cares the safety of any projects of our customers operating. All the scaffolding systems we provide meet the corresponding production standards.


Using Sampmax Construction scaffolding construction, we remind customers to pay attention to these common problems:

The settlement of the foundation will cause local deformation of the scaffold. In order to prevent the collapse or toppling caused by local deformation, stilts or scissor supports are erected on the transverse section of the double-bent frame, and a set of vertical rods are erected in a row until the deformation zone is arranged outside. The horoscope or scissor support foot must be set on a solid and reliable foundation.


The deflection and deformation of the cantilever steel beam on which the scaffolding is rooted exceeds the specified value, and the anchor point at the rear of the cantilever steel beam should be reinforced. The top of the steel beam should be tightened with steel supports and U-shaped brackets to withstand the roof. There is a gap between the embedded steel ring and the steel beam, which must be secured with a horse wedge. The steel wire ropes at the outer ends of the hanging steel beams are checked one by one and all tightened to ensure uniform force.
If the scaffolding unloading and pulling connection system is partially damaged, it must be restored immediately according to the unloading pulling method formulated in the original plan, and the deformed parts and members shall be corrected. Correct the outward deformation of the scaffold in time, make a rigid connection, and tighten the wire ropes at each unloading point to make the force uniform, and finally release the inverted chain.

During construction, the erection sequence must be strictly followed, and the connecting wall poles should be erected while erecting the outer frame, so as to be firmly connected to the structural frame column.

The poles should be vertical, and the poles should be staggered and bottomed from the first floor. The verticality deviation of the vertical pole shall not be greater than 1/200 of the erection height, and the top of the vertical pole should be 1.5m higher than the roof of the building. At the same time, the vertical pole joints must adopt butt fasteners except for the lap joint on the top layer.

The bottom of the scaffold must be equipped with vertical and horizontal sweeping rods. The vertical sweeping rod should be fixed on the vertical pole not more than 200mm away from the surface of the shim block with right-angle fasteners, and the horizontal sweeping rod should be fixed immediately below the vertical sweeping rod by right-angle fasteners. On the pole.

There is a flat net inside the operating shelf, and a 180mm high and 50mm thick wooden foot guard is arranged at the end and outside of the shelf. The scaffolding of the operating layer shall be laid fully and stably.


When laying the scaffold board butt, there are two horizontal horizontal rods at the joints, and the joints of the scaffold boards laid by overlapping must be on the horizontal horizontal rods. No probe board is allowed, and the length of the scaffold board shall not exceed 150mm.

The large crossbar should be placed under the small crossbar. On the inside of the vertical rod, use right-angle fasteners to fasten the vertical rod. The length of the large crossbar should not be less than 3 spans and not less than 6m.

It is used as an operating frame during the structure and decoration construction stage. It is a double-row double-pole fastener scaffold with a vertical distance of 1.5m, a row distance of 1.0m, and a step distance of 1.5m.


In the erection, every other layer of the outer frame must be firmly tied to the structure in time to ensure safety during the erection process. The vertical and horizontal deviation of the rods must be corrected along with the erection, and the fasteners must be tightened appropriately.
Key points of scaffolding removal construction

The demolition of scaffolding and formwork support system should be carried out strictly in accordance with the requirements of relevant technical standards and special plans. During the demolition process, the construction and supervision unit should arrange for special personnel to supervise.


Scaffolding must be dismantled from top to bottom layer by layer. Simultaneous operation of up and down is strictly prohibited, and the connecting wall parts should be removed layer by layer along with the scaffolding. It is strictly forbidden to dismantle the whole layer or several layers of the connecting wall before dismantling the scaffolding.

When the height difference of sectioned demolition is greater than two steps, connecting wall pieces should be added for reinforcement.

When removing the scaffolding, remove the nearby power cord first. If there is a buried power cord underground, take protective measures. It is strictly forbidden to drop fasteners and steel pipes around the power cord.

Dismantled steel pipes, fasteners and other accessories are strictly prohibited from being thrown onto the ground from a height.


The removal of the vertical pole (6m length) must be carried out by two persons. The vertical pole within 30cm under the main horizontal pole is forbidden to be removed by one person, and it is required to complete the removal before the step of the upper level bridge is removed. Improper operation may easily cause a high-altitude fall (including People and things).

The large crossbar, scissor brace, and diagonal brace should be removed first, and the middle butt fasteners should be removed first, and the end buckle should be supported after holding the middle; at the same time, the scissor brace and diagonal brace can only be removed on the demolition layer, not all at once, remove the scissor brace Safety belts must be worn at the time, and two or more people must cooperate to remove them.

The connecting wall parts must not be dismantled in advance. They can only be removed when they are removed layer by layer to the connecting wall parts. Before the last connecting wall parts are removed, throwing supports should be set on the vertical poles to ensure that the vertical poles are being removed. stability.
