Description

Device for connecting cantilever scaffold section steel and scaffold upright rod

Technical Field

The utility model belongs to the technical field of the scaffold is built.

Background

The cantilever scaffold is a scaffold system which is provided with a cantilever beam and builds a steel pipe scaffold on the cantilever beam. The key points of the cantilever scaffold are the fixed structure of the fixed end of the cantilever beam and the connection structure of the steel pipe scaffold and the cantilever beam.

In the construction of the overhanging scaffold, a scaffold upright rod steel pipe is erected on an I-shaped steel, in order to prevent the steel pipe from sliding, the connection between a steel pipe scaffold and a cantilever beam is still connected by welding in the actual construction at present, namely, a short reinforcing steel bar stub is welded on the I-shaped steel, and then the upright rod steel pipe sleeves the section of reinforcing steel bar to prevent sliding when the scaffold is erected. And the welding position of the short steel bar head is determined according to the size of the scaffold designed after the I-shaped steel is installed. This causes some drawbacks: 1. the I-shaped steel cantilever beam is repeatedly heated and then the surface is burnt during welding connection; 2. the welding construction difficulty is large, and the building or dismantling operation is inconvenient; 3. the welding needs a power supply and equipment, electric sparks and air pollution are generated during operation, and the welding cannot be carried out during power failure; 4. when the scaffold is disassembled and turned to another scaffold project, the scaffold is not easy to be reused due to different designed sizes, so that the position of the positioning steel bar welded on the I-steel needs to be cut and then welded again at a new position; 5. the welded positioning steel bar is a section of short steel bar head, and the I-shaped steel cannot be tightly stacked due to the existence of the section of steel bar after the I-shaped steel is recovered, so that the storage space of the I-shaped steel is influenced.

Although several connecting devices such as CN 105113775A, CN 108612296A are disclosed, the parts of the connecting device are complex and inconvenient to operate and are not perfect integral structures. The connecting device only fixes the upper edge of the section steel, and the bearing capacity of the section steel is not fully utilized. And the parts can fall off during operation to form a safety hazard. Therefore, a quick and integral connecting device is invented to avoid the defects.

SUMMERY OF THE UTILITY MODEL

For solving the problem among the prior art, the utility model provides a device convenient to scaffold frame shaped steel and scaffold frame pole setting rigid coupling encorbelment, its concrete structure is:

a device for connecting an overhanging scaffold section steel and a scaffold upright rod comprises a scaffold upright rod connecting part and an overhanging scaffold section steel connecting part which are fixedly connected into a whole, wherein the scaffold upright rod connecting part is a steel pipe, and the pipe diameter of the steel pipe is matched with that of the scaffold upright rod; the cantilever scaffold section steel connecting part is made of square channel steel, and a notch formed by enclosing a square channel steel bottom plate and two side edge plates is matched with the cantilever scaffold section steel; the scaffold upright rod connecting part steel pipe is vertically and fixedly connected on the plane of the outer side of the bottom plate; the inner side of the bottom plate is provided with an anti-slip high-strength silica gel pad.

The utility model has the advantages that: the device is simple and easy to operate, convenient to operate, high in safety, high in construction speed and free of damage to the section steel.

Drawings

FIG. 1 is a schematic view of the present apparatus;

fig. 2 is a side structure based on fig. 1.

In the figure: scaffold frame pole setting connecting portion 1, the scaffold frame shaped steel connecting portion 2 that encorbelments, anti-skidding high strength silica gel pad 3, scaffold frame shaped steel 4 encorbelments.

Detailed Description

The structure of the present invention will be described in detail with reference to the accompanying drawings, and as shown in fig. 1-2, an overhanging scaffold section steel and scaffold upright connecting device comprises a scaffold upright connecting portion 1 and an overhanging scaffold section steel connecting portion 2 which are fixedly connected into a whole, wherein the scaffold upright connecting portion 1 is a steel pipe with a diameter matching the scaffold upright; the cantilever scaffold section steel connecting part 2 is made of square channel steel, and a notch formed by enclosing a square channel steel bottom plate and two side edge plates is matched with the cantilever scaffold section steel 4; the scaffold upright rod connecting part 1 is fixedly connected on the outer side plane of the bottom plate through a steel pipe; the inner side of the bottom plate is provided with an anti-slip high-strength silica gel pad 3.

The use method of the device comprises the following steps:

firstly, the upper surface of the cantilever scaffold profile steel is cleaned, and the surface of the anti-sliding high-strength silica gel pad is cleaned.

And secondly, clamping the groove openings of the connecting parts of the cantilever scaffold section steel to the cantilever scaffold section steel.

And thirdly, inserting the scaffold upright rod into the circular sleeve of the scaffold upright rod connecting part, thereby completing the operation.

The thickness of the connecting part 1 of the upright stanchion of the scaffold and the hardness of steel materials meet the stress requirement of the structural member. Scaffold frame pole setting connecting portion 1 adopts full welding when welding with scaffold frame shaped steel connecting portion 2 that encorbelments, guarantees the firm of structure, and scaffold frame pole setting connecting portion 1's welding angle is not limited to perpendicular setting, also can possess certain inclination to scaffold frame pole setting connecting portion 1 and the design angle of the scaffold frame shaped steel connecting portion 2 that encorbelments are accurate. The scaffold frame shaped steel connecting portion 2 that encorbelments can adopt the channel-section steel segment of size and 4 adaptations of scaffold frame shaped steel that encorbelments, also can adopt bottom plate, curb plate to stabilize the welding and make. The utility model discloses the anti high strength silica gel pad of sliding 3 that uses in can install on the bottom plate side when the installation, fill up between bottom plate and girder steel, also can adopt other modes to notice in advance and fix on the bottom plate face, make this device be integrative. The anti-slip high-strength silicone rubber pad 3 can be replaced by other materials with the friction coefficient equivalent to that of the pad.

The utility model relates to a welding connection constructs, is exclusively used in the scaffold pole setting and the connection of the scaffold frame shaped steel (girder steel) of encorbelmenting, avoids the problem that leads to shaped steel surface structure destruction to shaped steel structure self welding. The device is simple and easy to operate, convenient to operate, high in safety, capable of being used in a self-circulation mode, high in construction speed and free of damage to the section steel.
