Problems solved by technology
The disadvantage of this method is that the anchor bolts need to be cut off in the later stage, and there are problems such as labor-intensive, waste of materials, and rust on the head of the anchor bolts after cutting off.
[0003] The existing anchor bolts are directly embedded in the reinforced concrete floor, and are fixed in the floor when the floor steel bars are bound. After the cantilever scaffold is used and the I-beam is removed, the exposed part is cut off with a cutting tool such as a grinding wheel saw. Each anchor Bolts can only be used once and cannot be reused, so it will cause serious waste

Embodiment 1
[0029] refer to figure 1 As shown in the figure, a fixed structure of a cantilevered I-beam 105 is shown in the figure, and the fixed structure includes: a flat steel 101, an anchor bolt 102, a pressure plate 107, a nut 108 and at least two of the cast-in-place floor slabs 104. Root cannula 103 .
[0030] The I-beam 105 to be fixed is disposed above the cast-in-place floor slab 104 and between the two sleeves 103 , and a pressing plate 107 is provided at the top of the I-beam 105 .
[0031] The anchor bolts 102 penetrate through the casing 103 and are rigidly connected to the flat steel 101 disposed under the cast-in-place floor slab 104 .
[0032] Preferably, the nut 108 is a double nut structure. Further, an anti-skid gasket is also provided between the nut 108 and the pressing plate 107 .
[0033] Preferably, a hardwood wedge 106 is also filled between the pressing plate 107 and the cast-in-place floor plate 104 .
[0034] Preferably, the anchor bolts 102 are connected ...

The invention discloses a fixing structure of cantilever I-shaped steel. The fixing structure comprises flat steel, anchor bolts, a pressing plate, nuts and at least two sleeves arranged in a cast-in-place floor. I-shaped steel to be fixed is arranged above the cast-in-place floor and located between the two sleeves, and a pressing plate is arranged at the top end of the I-shaped steel. The anchor bolt penetrates through the sleeve and is in rigid connection with flat steel arranged below the cast-in-place floor, and the upper end of the anchor bolt penetrates through the pressing plate and completes fastening of the pressing plate through a nut. The fixing structure of the cantilever I-shaped steel is simple in structure, clear in stress and convenient to operate; repeated use can be achieved, materials are saved, and cost is reduced; and mounting is simple, and dismounting is rapid.
Description
technical field [0001] The invention belongs to the technical field of construction structures, and in particular relates to a fixed structure of cantilevered I-beams. Background technique [0002] At present, most of the construction sites use pre-embedded anchor bolts to fix the I-beam of the cantilevered scaffolding. The conventional practice is to pre-embed the anchor bolts in the floor during the construction of the concrete floor. Buried anchor bolts. The disadvantage of this method is that the anchor bolts need to be cut off in the later stage, and there are problems such as labor-intensive, waste of materials, and rust at the head of the anchor bolts. [0003] The existing anchor bolts are directly embedded in the reinforced concrete floor, and fixed in the floor when the floor steel bars are tied. After the cantilever scaffold is used and the I-beam is removed, the exposed part is cut off with a cutting tool such as a grinding wheel saw. The bolts can only be used...
