Abstract

The utility model relates to a light-weight steel scaffold board and a special fastener thereof. The light-weight steel scaffold board is connected with a scaffold by the special fastener for construction works. The lower part of the scaffold board is provided with a cross bar (1), the middle part of a cross section is provided with a deep slot (2), both sides of the deep slot (2) are provided with a triangular wire slot (3), and both ends of the lower part of the triangular wire slot (3) are provided with a U-shaped component (4). When the strength and the rigidity are the same, the weight of the utility model is one third lighter than that of the existing steel scaffold board, and the thickness of the utility model is only 1 to 1.5mm. The special fastener is formed by the way that a pressing board with a hook-shaped pressing head is added on the existing fastener which is composed of a clamping seat and a clamping cover. The special fastener is arranged below the scaffold board and is connected with the scaffold, and the requirement to the spacing of upright bars of the scaffold does not exist.

Description

Lightweight section scaffold floor and dedicated fastener thereof

The application relates to the building operations equipment, particularly Steel scaffold board and fastener.

In the building operations at present, generally adopt its section to be roughly the Steel scaffold board of flute profile.Because section structure is unreasonable, the cross section square is little, and strength and stiffness are poor, and load capacity is little.In order to satisfy the construction needs, steel plate needs the thick 2.75～3mm that reaches, thereby steel using amount is many, and weight is big, and mounting or dismounting labour intensity is big, uses inconvenient.

One of purpose of the application is exactly to provide for overcoming above-mentioned shortcoming that a kind of cross section square is big, the higher lightweight section scaffold floor of strength and stiffness.It can significantly alleviate the weight of scaffold floor guaranteeing have under the prerequisite of sufficient intensity and rigidity; Two of purpose provides the fastener that is used with this lightweight section scaffold floor, and it can be connected scaffold floor with the transverse tube of scaffold is convenient under scaffold floor securely.

For one of achieving the above object, the section of lightweight section scaffold floor is band stull " mountain " font, there is a deep trouth at the section middle part, there is a triangle shallow slot at this deep trouth to the middle part of a left side (right side) end, the bottom of a left side (right side) end is a U-shaped, and stull is arranged at the bottom of scaffold floor, its two ends respectively with the welding of the bending part of U-shaped, weld with the bottom of deep trouth at the middle part, and this scaffold floor is connected with the transverse tube of scaffold by dedicated fastener.

Be further to increase cross section square and side degree, said deep trouth bottom is circle or near round shape preferably; Also can be other shape, but processing and forming be difficult.

Light-duty firm scaffold floor is compared with existing Steel scaffold board, is satisfying under construction required same load, intensity and the rigidity, and the former steel plate thickness only is 1～1.5mm, and scaffold floor weight can alleviate 1/3rd.

For achieve the above object two, said dedicated fastener is to increase a pressing plate on the fastener basis of being made up of deck, Ka Gai of generally adopting at present, this pressing plate and deck are rigidly connected, pressing plate has a flanging hook-type pressure head partly that can block said U-shaped.

Use this dedicated fastener, can below the transverse tube of scaffold floor and scaffold be tightened together at scaffold floor easily, to the vertical pole ' s span no requirement (NR) of scaffold, greatly convenient construction helps improving site operation efficient.

Further specify the application's content below in conjunction with drawings and Examples.

Embodiment 1 (Fig. 2,3): lightweight section scaffold floor, its section is band stull 1 " mountain " font, there is a deep trouth 2 at the middle part, there is a triangle shallow slot 3 at this deep trouth to the middle part of a left side (right side) end, the bottom of a left side (right side) end is a U-shaped 4, stull 1 is arranged at the bottom of scaffold floor, its two ends respectively with bending part 11 welding of U-shaped 4, weld the bottom of middle part and deep trouth 2.

This scaffold floor adopts the thick steel sheet clod wash one-shot forming of 1～1.5mm.Be increase frictional force, but dense punching (Fig. 1) on the plate face, and a scaffold floor can have many stulls 1, the about 400mm of its spacing

Embodiment 2 (Fig. 3): the bottom sub-circular 5 of the deep trouth 2 on the section of this lightweight section scaffold floor, all the other are with embodiment 1.

Embodiment 3: the section structure of lightweight section scaffold floor is with embodiment 1 or embodiment 2, and the plate face is of a size of: thick 1～1.5mm, and wide 250mm, long 3000mm, high 50～57mm, the flanging 11 high 6～7mm of U-shaped part, the stull 1 of scaffold floor has 6.

Embodiment 4 (Fig. 4,5): the deck 7 that the useful pivot pin of dedicated fastener connects covers 8 with card, can turn round opening and closing.A pressing plate 9 and deck 7 rivetings are arranged in addition together.Pressing plate 9 has a hook-type pressure head 10 that can block U-shaped bending part 11 (Fig. 6).

Embodiment 5 (Fig. 4,6): the using method of dedicated fastener is below deck 7 to be stuck on the transverse tube 6 of scaffold at the lightweight section scaffold floor, pressing plate 9 is pressed in the U-lag of scaffold floor bottom and blocks flanging 11, to block again and cover 8 and close with deck 7, fastening with screw, the steel pipe 6 of lightweight section scaffold floor and scaffold just links together securely.
