Abstract
The utility model belongs to building construction supporting structures, and particularly relates to an overhanging fire control corridor supporting structure. The problem that when a fire control corridor is not attached to a building, a conventional overhanging I-beam can not be used for supporting a formwork is solved. The overhanging fire control corridor supporting structure comprises a plurality of overhanging I-beams, and the ends of the I-beams are fixed by a round steel pressing ring embedded in a body. The overhanging I-beams comprise long overhanging I-beams and short overhanging I-beams, simple I-beams which are perpendicular to the overhanging I-beams are welded and fixed on the upper sides of the long overhanging I-beams, and the two ends of the simple I-beams are welded and fixed. The overhanging fire control corridor supporting structure is simple in structure and capable of meeting the demand of a fire control corridor formwork supporting system with a large overhanging distance, and achieves the purpose that the formwork supporting system meets the bearing force requirement of a fire control corridor.
Description
Technical field
The utility model belongs to building operations braced structures, specifically the one fire-fighting vestibule braced structures of encorbelmenting.
Background technology
Fire-fighting vestibule generally can be set in high level and super highrise building to meet fire protection requirement, fire-fighting vestibule can be close to building form bracing system conventionally, and cantilever span is less.Some engineering fire-fighting vestibule is not close to building, and the maximum distance of encorbelmenting is larger, can not simply rely on the routine i iron of encorbelmenting to carry out shuttering supporting.
Summary of the invention
When the utility model is not close to building in order to solve fire-fighting vestibule, the routine i iron of encorbelmenting cannot carry out the problem of shuttering supporting, and the one fire-fighting vestibule braced structures of encorbelmenting is provided.
The utility model is taked following technical scheme: the one fire-fighting vestibule braced structures of encorbelmenting, comprise the some i iron of encorbelmenting, the some i iron ends of encorbelmenting are fixed by the round steel pressure ring being embedded in main body, the i iron of encorbelmenting comprises long encorbelment i iron and the short i iron of encorbelmenting, wherein the long i iron upside of encorbelmenting is welded with the simple and easy i iron vertical with the i iron of encorbelmenting, and simple and easy i iron two ends are welded and fixed.
Described simple and easy i iron has 2, and 2 simple and easy i iron stack and weld together.
On the every described i iron of encorbelmenting, there are 3 for fixing round steel pressure ring.
Described round steel pressure ring is U-shaped, and round steel pressure ring downside is embedded in concrete, and the U-shaped pin place of round steel pressure ring upside is fixed on compressing tablet by nut, and the i iron of encorbelmenting is arranged in round steel pressure ring and compressing tablet.
Compared with prior art, the utility model is simple in structure, meets the fire-fighting vestibule form bracing system of the distance of encorbelmenting more greatly, has reached form bracing system and has met the completely object of fire-fighting vestibule requirement for bearing capacity.

Fig. 2 is that the utility model fire-fighting corridor construction completes plan view;
Fig. 3 is the utility model i iron end fixed structure schematic diagram of encorbelmenting;
The long i iron of encorbelmenting of 1-in figure, the simple and easy i iron of 2-, the short i iron of encorbelmenting of 3-, 4-round steel pressure ring, 5-compressing tablet.
Detailed description of the invention
As shown in Figure 1, 2, the one fire-fighting vestibule braced structures of encorbelmenting, comprise the some i iron of encorbelmenting, the some i iron ends of encorbelmenting are fixed by the round steel pressure ring 4 being embedded in main body, the i iron of encorbelmenting comprises long encorbelment i iron 1 and the short i iron 3 of encorbelmenting, wherein long i iron 1 upside of encorbelmenting is welded with the simple and easy i iron 2 vertical with the i iron of encorbelmenting, and simple and easy i iron 2 two ends are welded and fixed.
Described simple and easy i iron 2 has 2, and 2 simple and easy i iron 2 stack and weld together.
On the every described i iron of encorbelmenting, there are 3 for fixing round steel pressure ring 4.
Described round steel pressure ring 4 is U-shaped, and round steel pressure ring 4 downsides are embedded in concrete, and the U-shaped pin place of round steel pressure ring 4 upsides is fixed on compressing tablet 5 by nut, and the i iron of encorbelmenting is arranged in round steel pressure ring 4 and compressing tablet 5.
The utility model concrete operating procedure in engineering is as follows:
In completed substructure, set up freely-supported i iron, select 2 20# freely-supported i iron to stack setting, and i iron is carried out to welding procedure, guarantee that two i iron connect into entirety, utilize tower crane that i iron is winched to and sets up floor and be positioned over staircase with indoor absolute altitude place, two end bearing places and structure reinforcing bars are welded into entirety to ensure its stability.
The long i iron and freely-supported i iron is welded and fixed and both sides steel bar end is welded and fixed of encorbelmenting, the short i iron of encorbelmenting is directly encorbelmented.The i iron end dependence of encorbelmenting has been embedded in main body San road round steel pressure ring and has fixed.Reduce the cantilever span of the i iron of encorbelmenting, met support system load requirement.
Welded reinforcement short column on the i iron of encorbelmenting of installing, guarantee that every frame pipe is all inserted in this reinforcing bar short column to ensure the stability of scaffold system, thereby make whole i-beam structure form a stable shuttering supporting basis, on this, carry out the supporting template system construction of fire-fighting vestibule.
