Description

Cantilever large formwork support device

technical field

The utility model relates to a supporting device for a cantilevered large formwork.

Background technique

At present, part of the construction formwork of the outdoor cantilever slab is erected using traditional wooden formwork and nailing construction, and the lower support is generally made of wooden joist and scaffolding pipes, so the stability and safety are difficult to guarantee. In terms of quality, it is easy to cause the root of the cantilever slab to break, the appearance of the finished product of the cantilever slab of the same specification is different, and the molding effect is poor. In terms of safety, especially in outdoor construction, there is a safety risk to the workers themselves in the project of nailing the formwork of the overhanging part. This problem is especially prominent as the floors become higher and higher. In addition, the stability of the wooden formwork after installation cannot be measured. In the process of concrete pouring, with the application of construction stress, hidden dangers of construction safety have been buried.

Cantilever structure is one of the common structural forms in engineering structures, such as awnings, overhanging eaves, external balconies, overhanging corridors, etc. in construction projects. This structure is a beam or plate cantilevered from the main structure to form a cantilever structure. It is still a beam-slab structure in essence.

If the super-high and large-size cantilevered concrete structure adopts the traditional floor-standing steel pipe scaffolding support system, the construction investment will be large, the construction period will be long, and the safety risk will be high. The super-high and large-scale cantilevered concrete structure brings great difficulties to the structural construction.

Contents of the invention

The technical problem to be solved by the utility model is to provide a cantilevered large template support device with a stable structure and adjustable height.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is described in detail with reference to the accompanying drawings.

As shown in Figure 1-2, the cantilevered large template support device of the utility model is installed on the beam 5, which includes a plurality of triangular brackets, and each triangular bracket includes fixedly connected horizontal bars 1, vertical bars 2 and The oblique bar 3 is also provided with a reinforcing bar 4 between the oblique bar 3 and the cross bar 1 and the vertical bar 2, and a plurality of reinforcing bars 4 are connected with the oblique bar 3 by bolts. A plurality of triangular brackets are connected and fixed by connecting rods 7 , and a formwork 8 is placed on the cross bar 1 .

Embedded studs 6 are arranged inside the beam 5 , and vertical plates 12 for connecting with the existing beam 5 are arranged at the upper and lower ends of the vertical bar 2 . The vertical plate 12 is provided with a strip hole, and the left and right sides of the strip hole are provided with positioning teeth 14, and the vertical bar 2 is fixed by connecting the nut 11 with the embedded stud 6, and the nut 11 is sleeved with a positioning tooth 14. The locking teeth 13, the upper part and the lower part of the vertical bar 2 are respectively fixed on beams 5 of different heights. When the nut 11 is tightened, the locking teeth 13 and the positioning teeth 14 are locked to complete the fixing. When the nut 11 is unscrewed and removed, the locking teeth 13 are separated from the positioning teeth 14. Now the vertical bar 2 can be moved to adjust its height.
