Description
Technical Field
The utility model belongs to the technical field of the construction, especially, relate to an automatic over-and-under type scaffold's connecting device.
Background
The automatic lifting scaffold is supported by the built wall and concrete structure. The height is constant, and the height is generally 2 to 3 floors, and the height is divided into 4 steps, 6 steps and 8 steps. During construction, on the stand column of each wall body, a plurality of screw rods and nuts are embedded at certain intervals, a guide upper hanging support is fixed on each screw rod, the climbing shed is installed in the guide seats, the middle part of the climbing shed is connected, and the climbing shed is also connected with a fastener by using steel pipes as a traditional scaffold. After a floor is built, the electric hoist arranged on the guide seat lifts the whole frame body up by one floor. And then construction is carried out. Therefore, no matter how high the building is built, the frame body does not need to be erected again, the height of the frame body is kept unchanged all the time, and the whole frame body is lifted up layer by layer. When the floor is higher, automatic rising scaffold frame has obvious advantage than the tradition scaffold frame of putting up. However, the automatic lifting scaffold is mostly used in concrete or concrete shear wall structures and is less applied in steel structures. The reason is that if the guide seat of the scaffold is connected to the steel member by directly forming a hole on the steel member, not only the construction cost is high, but also the stress performance of the steel member is seriously affected.

Detailed Description
For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings and examples.
Example (b): as shown in fig. 1 to 3, a connecting device for an automatic lifting scaffold includes a reinforcing rib 2 and a connecting base 3. The reinforcing ribs 2 are welded or fixed on the steel beam 1 of the steel structure through other parts, usually two blocks are in a group and arranged in parallel, two bolt holes 5 are preset in the reinforcing ribs 2, the diameters of the bolt holes 5 are 20mm, and the reinforcing ribs are used for inserting bolts 4 so as to install the connecting seats 3. The connecting seat 3 includes a base plate 31, and one side of the base plate 31 is welded with a plurality of connecting plates 32 perpendicular to the base plate 31, and usually two connecting plates 32 parallel to each other are welded, so that the number of the connecting plates 32 can be increased when the load-bearing requirement is large.
The base plate 31 and the connecting plate 32 are formed by welding steel plates with the thickness of 10mm, the processing cost is low, the base plate 31 and the connecting plate 32 are firm and durable, and the sizes of the base plate 31 and the connecting plate 32 can be set to be various specifications according to different steel beams 1. The base plate 31 is provided with guide holes 311 for connecting scaffold guides, and the preferred number of the guide holes 311 is two, and the diameter is 30 mm. Two bolt holes 5 for connecting the reinforcing rib 2 are arranged on the connecting plate 32, the positions of the two bolt holes 5 are matched with the positions of the bolt holes 5 on the reinforcing rib 2, and the diameter of the bolt holes 5 is 20 mm.
During construction, firstly, the reinforcing rib 2 is welded on the steel beam 1 of the steel structure according to the distance between the two connecting plates 32 on the connecting seat 3, and then the connecting plates 32 of the connecting seat 3 are fixedly connected with the reinforcing rib 2 through the bolts 4. After that, the guide seat and the lifting device of the automatic lifting scaffold are fixedly connected with the connecting seat 3 through bolts, and the dead weight and the lifting load of the automatic lifting scaffold are transmitted to the connecting seat 3 through the guide seat and then transmitted to the steel beam 1 through the connecting seat.
This embodiment connecting device with automatic rising scaffold frame through assembled connected node reasonable with the girder steel 1 of steel construction be connected, site operation convenient and fast has good atress performance and good rigidity simultaneously. The connecting device is low in processing cost, economical and practical.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
