Abstract
The utility model discloses a reusable overhanging I-beam fixing device. The device mainly comprises an upper U-shaped rebar, a lower U-shaped rebar and straight thread sleeves, wherein the upper and lower U-shaped rebars are connected by the straight thread sleeves. The device has the following advantages: the device has a simple structure and only has a few parts; the device is convenient to install, and the lower U-shaped rebar penetrates through a PVC (polyvinyl chloride) casing embedded in a concrete floor slab and is screwed into the two ends of the straight thread sleeves with the upper U-shaped rebar at the same time; and the device can be dismantled and reused, thus reducing the steel investment and saving the construction cost while ensuring the stability of the overhanging I-beam.
Description
Technical field
The utility model relates to building operations and uses the fixing of the steel I-beam of encorbelmenting, especially a kind of reusable steel I-beam fastening devices of encorbelmenting.
Background technology
The steel I-beam builder's jack is often adopted in outer protection in the high-building construction, and the fixing means of the existing steel I-beam of encorbelmenting has pre-buried method, and it is that a few font reinforcing bar draw rings are earlier pre-buried in concrete floor as the fixture of the steel I-beam of encorbelmenting.But behind the dismounting builder's jack, a few font reinforcing bar draw rings will be flushed floor face and cut off, and can not reuse, thereby disposable input amount be big, cause steel to waste in a large number.
The utility model content
The technical problem that the utility model will solve provides a kind of steel I-beam fastening devices of encorbelmenting simple in structure, easy for installation, reusable.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the reusable steel I-beam fastening devices of encorbelmenting; Mainly comprise U-shaped reinforcing bar, following U-shaped reinforcing bar and straight screw sleeve, last U-shaped reinforcing bar is connected through straight screw sleeve with following U-shaped reinforcing bar.
The external screw thread of last U-shaped reinforcing bar and following U-shaped reinforcing bar and the internal thread of straight screw sleeve are complementary.
Straight screw sleeve is positive and negative screw thread type straight screw sleeve.
Following U-shaped reinforcing bar passes the PVC sleeve pipe.
The PVC casing inner diameter is slightly larger than down the U-shaped reinforcing bar.
To the deficiency of the existing pre-buried fixation of steel I-beam of encorbelmenting, the inventor has designed the steel I-beam fastening devices of encorbelmenting of the utility model, and it is simple in structure, has only several component such as last U-shaped reinforcing bar, following U-shaped reinforcing bar and straight screw sleeve; Easy for installation, following U-shaped reinforcing bar is passed pre-buried PVC sleeve pipe and last U-shaped reinforcing bar in concrete floor be screwed into the straight screw sleeve two ends simultaneously and get final product; This installs dismountable repeated use, when the steel I-beam of guaranteeing to encorbelment is firm, has reduced the steel input, has practiced thrift construction cost.

Among the figure: U-shaped reinforcing bar on 1,2 times U-shaped reinforcing bars, 3 straight screw sleeves, 4PVC sleeve pipe, 5 concrete floors, 6 steel I-beams, 7 timber wedges.
The specific embodiment
As shown in Figure 1; The reusable steel I-beam fastening devices of encorbelmenting of the utility model; Mainly comprise U-shaped reinforcing bar 1, following U-shaped reinforcing bar 2 and straight screw sleeve 3; Straight screw sleeve 3 is positive and negative screw thread type straight screw sleeve, and the last U-shaped reinforcing bar 1 and the external screw thread of following U-shaped reinforcing bar 2 and the internal thread of straight screw sleeve 3 are complementary, and last U-shaped reinforcing bar 1 is connected through straight screw sleeve 3 with following U-shaped reinforcing bar 2.
When making the utility model, need to confirm to go up the width and the length of U-shaped reinforcing bar 1, following U-shaped reinforcing bar 2, and will go up the termination Che Sicheng external screw thread of U-shaped reinforcing bar 1 and following U-shaped reinforcing bar 2 according to the thickness of concrete floor 5 and the wide height of steel I-beam 6.Confirm the length of PVC sleeve pipe according to the thickness of concrete floor 5, the PVC casing inner diameter is slightly larger than down U-shaped reinforcing bar 2, and according to the position of steel I-beam 6 that it is pre-buried in concrete floor 5.
Shown in Fig. 2 to 4; When using the utility model; After treating that steel I-beam 6 is in place; Following U-shaped reinforcing bar 2 is passed pre-buried PVC sleeve pipe and last U-shaped reinforcing bar 1 in 5 li of concrete floors be screwed into straight screw sleeve 3 two ends simultaneously, can will go up U-shaped reinforcing bar 1 with spanner rotation straight screw sleeve 3 and be screwed into straight screw sleeve 3 simultaneously with following U-shaped reinforcing bar 2; Insert fixing the getting final product of gap wedging of fastening devices and steel I-beam 6 again with timber wedge 7.
Claims (5)
