Scaffolding Planks

The technological process of suspension scaffold

Horizontal cantilever, vertical sweep lever, vertical bar, transverse floor, small crossbar, big crossbar (joist), scissors support, wall, foot plate, fence, rail and rail.

Fixed distance positioning.According to the construction requirements, within the four corners of the building, the inner and outer vertical rod should be removed from the wall and mark;Straightening with steel tape, dividing pole position, and using small bamboo pieces to mark the pole;The mat and base should be placed accurately on the positioning line. The pads must be laid flat and not suspended.

In the process of erection of the first layer of the scaffolding, along every frame around with an inclined support, in addition to the corner two-way open, for the parts of the scaffolding and the main structure of the wall a reliable connect rear can dismantle.When the scaffolding operation layer is two steps higher than the wall, it is appropriate to arrange the outer row, and then the inner row.The rest is set up by the construction requirements.

Common scaffolding material requirements

6. The horizontal suspension rod of the shape steel is made of channel 16a, and the inclined rod is adopted with a 5.6 x 3 x 6.0 mm steel pipe.
7. The diameter of the embedded bolt is 20.0 mm.

Selection of scaffold construction scheme

Considering the construction period, quality and safety requirements, this project should consider the following points in selecting a plan:

1. The structure design of the frame is designed to ensure that the structure is safe and reliable, and the cost economy is reasonable.

2. Within the prescribed conditions and within the prescribed period of use, the safety and durability of the expectations can be fully met.

3. When choosing materials, strive to be common and recycle and easy to maintain and maintain.

4. When selecting the structure, make sure that the force is clear, the construction measures are in place and the lifting and lifting is convenient for inspection and acceptance;

5. In combination with the above mentioned points, the scaffolding of the scaffold must conform to the requirements of the JCJ59-99 inspection standard, which shall conform to the relevant standards of jiangxi province civilization standard chemical industry.

6. Combined with the above scaffold design principles, combined with the actual situation of the project, taking into consideration the previous construction experience, the following scaffolding scheme is adopted: ordinary suspension

What are the kinds of scaffolding in the construction

Use scaffolding material can build all kinds of formwork support frame, including beamform, cavity plate and beam slab mould and die box foundation, and used the bracket beam plate template. In the cavity plate and beam slab mould stents, support height > 4.0 m, known as the “high racks, with early dismantling requirements and its device, known as” early brace of the template system “.
Fastener type, bowl of button and the door type steel pipe ringlock system materials can be used for the construction formwork support frame, and each has its characteristics.According to its structure can make the following categories:
(1) according to the structural classification
1) pillar type racks (pillar bearing frame);
2) (bent) type brace (formed by a row of pillars have horizontal tie connecting structure);
3) double row racks (formed by two rows poling racks);
4) space frame type racks or set of space and architecture (more).
(2) according to the truss structure system
1) geometric immutable truss structural support frame (conform to the stipulations of the truss rods slenderness, vertical plane diagonal set is not less than all of two direction structure frame of 1/2 of the sash);
2) the geometric immutable truss structural support frame (comply with scaffolding framework, but have a vertical plane diagonal sash less than 1/2 of the total framework of setting).
(3) by pillar type
1) ChanLi rod racks;
2) double stud support frame;
3) lattice column brace (supported by lattice column group formation frame).
4) hybrid pillar supporting frame (a mixture of ChanLi rod, double stud, lattice column brace).
(4) according to the level of frame is divided
1) the level of the structural don’t buy a small amount of setting diagonal or shear support brace;
2) one or several level enhancement layer set of racks, and can be divided into:
A. plate level strengthen layer (each set is only a single layer, diagonal set a third level sash or higher);
B. truss type level strengthen layer (each for double, and vertical diagonal Settings).

The ringlock scaffoding helps you a lot in the construction

Nowadays, many factories in the product came out in a relatively important link, it is for testing, so in the process of testing we need to test the product of what?This is what we need to know, so the ringlock scaffolding manufacturer’s product testing when testing?In the ringlock scaffolding products above we detect and firm performance, because of this
Ringlock scaffolding necessary complete, easy to use.Bowl buckles type steel pipe scaffold supporting design also have steel scaffolding, ramps board, ladder, cantilever rack and safety net support, and other functions of auxiliary components, can satisfy the various construction requirements, to create a favorable condition for the civilization construction. The construction site management and convenient. Bowl of fastener type steel pipe scaffold components lightweight, strong, especially scattered fittings, can be neatly stacked, not easily lost, facilitate site materials management, greatly reducing the material consumption.
Construction equipment that 2014 rings button scaffolding market situation will be good in 2013 as a whole. Domestic ringlock scaffolding market price of the first yi quarter of 2014 is expected to recover unevenly, the second quarter of the market will enter phase of digestive inventory, the price is expected to shock, home for the whole year round button scaffolding market will present “weak balance”.
Ringlock scaffold should use the same elevation of beam bottom elevation range, for larger height and span of a single component supporting bracket to use, for bar pull and poling axial stress calculation, in order to ensure the stability of the frame body and safety.
Standard packing: this kind of scaffolding you need less maintenance quantity, convenient loading and unloading, transportation is convenient, easy to store, suitability is strong. Economy applicable: rail can be removed using early turnover, save resources, saving wood square, save time and effort. Actually achieve energy conservation and environmental protection, economy is more practical.

Conditions for the frame scaffold to work in the construction

⑴ According to the building plan according to the door frame scaffolding of the bar size and draw the main mast position, the location of the hole and the structure of the building with the location, etc., to do the construction program design, and to the construction staff in detail.
⑵ into the scene of the mast and accessories should be classified stacking, proper custody. On the assembly and unloading process caused by the deformation of the collision, to timely correction, so as not to affect the installation.
⑶ set up frame scaffold of the site has been smooth and compaction, flatness difference within 25mm, and to do dangerous drainage slope to prevent water.
⑷ the ink line has been put.
