Description

Formwork support jacking for high-rise overhanging

Technical Field

The utility model belongs to the technical field of auxiliary tools for building construction, and particularly relates to a formwork support jacking for high-rise overhanging.

Background

The high-rise overhanging generally refers to a high-rise structure extending outwards on the house body, such as an eave, a balcony, and the like. In the construction process of high-rise overhanging, a mould is generally required to be erected first and then concrete is poured into the mould, and before the mould is completely solidified, the mould is required to be a supporting frame body with enough strength and sufficient stability, namely the supporting frame body.

On the other hand, the formwork support is a steel pipe support body which is built horizontally and vertically, and the outer side of the die is fixed by various steel pipes. Therefore, if the steel pipe frame directly supports the die steel pipe, at least the following 2 problems occur: 1. the supporting height of the steel pipe frame body is not necessarily exactly matched with the position height of the die steel pipe, if the supporting height is too high, the steel pipe frame body cannot be used, and if the supporting height is too low, the supporting height is insufficient; 2. the vertical steel pipe and the horizontal steel pipe are very difficult to directly prop against, the problem of slipping and deflection easily occurs, and finally the support is not in place.

Therefore, jacking is needed at this time, in other words, the jacking has at least the following 2 effects:

firstly, the effective height of the steel pipe support body is adjustable, so that the steel pipe support body can fully and properly support the die steel pipe;

and the second jacking end and the steel pipe frame body cannot slip between the other end and the die steel pipe, so that the full clamping and fixing are ensured.

The utility model patent publication No. CN216406185U, publication No. 2022.04.29, discloses a formwork support jacking capable of directly removing formwork, wherein the existing part in the structure is a bottom fixing part and a main stress rod, and the improved part is a force transmission supporting part and an upper tray.

The jacking in the patent of the utility model has the general structural principle as follows:

the force transmission support component continuously rotates upwards on the main stress rod, so that the upper tray props against the die steel pipe, the overhanging die can be propped, supported and fixed, and further, in order to avoid the problem of angle stagger between the upper tray and the die steel pipe, the upper tray can be clamped with the die steel pipe first, and then the bottom fixing component is rotated downwards, so that the problem of angle stagger between the upper tray and the die steel pipe is solved.

However, the greatest defect of the jacking in the actual use process is that the technical problem to be solved by the utility model is as follows:

the reinforced steel pipes used for the overhanging die are mostly round, but the reinforced steel pipes also have a plurality of I-shaped steel and C-shaped steel, so the universality of the upper tray is relatively poor, and the conventional common various overhanging die steel pipes cannot be stably supported.

Therefore, in summary, a flexible and general jacking capable of stably supporting both the circular steel tube and the i-steel and the C-steel is needed for the supporting frame matched with the high-rise overhanging die.

Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1-8, a formwork support for high-rise overhanging comprises a stud 1, a support ring 2 arranged on the stud 1, a pushing plate 3 arranged on the support ring 2, a middle pipe body 4 sleeved on the stud 1, an arc plate 5 and a U-shaped plate 6 respectively arranged at two ends of the middle pipe body 4, an opening 7 arranged on the arc plate 5 and the U-shaped plate 6 and used for penetrating through the stud 1, and an adjusting ring 8 screwed on the stud 1 and used for supporting the arc plate 5 or the U-shaped plate 6.

In this embodiment, the middle pipe body 4, the arc plate 5 and the U-shaped plate 6 are fixedly connected or integrally formed, the arc plate 5 faces upwards to support the circular die steel pipe a, and the U-shaped plate 6 faces upwards to support the die steel pipe a in the shape of i-steel or C-steel, so that the jacking can be stably supported and is not easy to slip when facing the circular steel, the i-steel or the C-steel.

Wherein the lower end of the stud 1 is inserted into a supporting steel pipe c, the supporting ring 2 is pressed on the supporting steel pipe c, the opening 7 is not in threaded connection with the stud 1, but only allows the latter to pass through, and the adjusting ring 8 is used for supporting the lower one of the arc-shaped plate 5 and the U-shaped plate 6.

Finally, the jacking can be stably installed at two ends and can be lifted and adjusted to effectively support the height, so that the whole overhanging die is efficient and comprehensive in jacking and supporting functions.

The upper end face of the stud 1 is provided with a limit cylinder 9 for being inserted into the middle pipe body 4 and the opening 7, and the diameter of the limit cylinder 9 is larger than the nominal diameter of the stud 1.

In this embodiment, the nominal diameter of the stud 1 refers to the diameter of the circular area where the protruding thread peaks are located, and the above sizes are set differently, so that the hole 7 and the middle pipe body 4 are not liable to damage the thread of the stud 1, otherwise the stud 1 is likely to fail, i.e. the adjusting ring 8 cannot be smoothly rotated and lifted.

The inner diameter of the middle pipe body 4 is equal to the diameter of the opening 7 and is 2-3mm larger than the diameter of the limit cylinder 9.

In this embodiment, the highest point of the adjusting ring 8 just touches the limiting cylinder 9, and at this time, the limiting cylinder 9 is still sleeved with the middle pipe body 4 and the opening 7, so that the relatively smaller hole mentioned above can ensure that the three-in-one component of the middle pipe body 4, the arc-shaped plate 5 and the U-shaped plate 6 is not easy to incline greatly, so that the jacking effect is more stable.

Furthermore, when the height of the adjustment ring 8 is relatively low, as is the case when the "three-in-one" component described above is separated from the stop cylinder 9, the latter, if it is intended to be activated again, requires manual alignment of the aperture 7 and the stop cylinder 9.

On the other hand, the three-in-one component has no anti-drop effect on the jacking, the adjusting ring 8 is blocked by the limiting cylinder 9, and the adjusting ring 8 has an anti-drop function.

The inner bottom surfaces of the arc-shaped plate 5 and the U-shaped plate 6 are provided with flat bottom grooves 10 for supporting the adjusting ring 8.

In this embodiment, if the flat bottom groove 10 is not present, the arc 5 and the adjusting ring 8 can only bear against part of the edge of the latter, which is quite unstable. Thus, 2 flat bottom grooves 10 ensure that at least the upper edge of adjusting ring 8 and the arcuate surface of arcuate plate 5 are not excessively worn.

In addition, the flat bottom groove 10 on the U-shaped plate 6 can be omitted, and the influence is not great after the arrangement is canceled.

The flat bottom groove 10 is circular in shape.

In this embodiment, the shape of the adjusting ring 8 is a circular ring, and the shape of the flat bottom groove 10 is a corresponding circular shape, and the two parts can be properly and precisely sleeved to supplement and strengthen the sleeved relationship between the middle pipe body 4 and the limiting cylinder 9.

The flat bottom groove 10 has a diameter larger than the opening 7.

In this embodiment, the outer diameter of the adjusting ring 8 is larger than the nominal diameter of the stud 1, so that the flat bottom groove 10 needs to be larger than the opening 7, but the former is not too large, otherwise the structural strength of the arc-shaped plate 5 and the U-shaped plate 6 is significantly reduced

The adjusting ring 8 is also provided with a second pushing plate 11.

In this embodiment, the adjusting ring 8, like the supporting ring 2, is required to rotate on the stud 1 to adjust its height, so the second pushing plate 11 is a labor-saving lever of the adjusting ring 8, compared with directly rotating the adjusting ring 8.

The second pushing plate 11 is provided on the lower surface of the adjusting ring 8.

In this embodiment, since the arcuate plate 5 and the U-shaped plate 6 themselves have a certain vertical width, the adjusting ring 8 also needs a sufficient vertical dimension, otherwise the latter is entirely retracted inside the former, and it is difficult to perform a rotating operation on the former.

Furthermore, the second pusher plate 11 cannot be relatively high on the adjusting ring 8, so that the lower surface arrangement is an optimal way, at least to ensure that the second pusher plate 11 cannot hit the arc-shaped plate 5 and the U-shaped plate 6.

An elastic supporting plate 12 for jacking up the die steel pipe a is further arranged on the upper end face of the limit cylinder 9.

In this embodiment, the elastic support plate 12 is made of conventional common rubber, and is adhered to the upper end surface of the limiting cylinder 9, so that when any one of the above-mentioned three-in-one component and the adjusting ring 8 is lost or fails, the jacking can still be used in an emergency and temporarily, and at this time, the actual effective length of the jacking can be adjusted by the support ring 2.

The elastic support plate 12 is circular in shape and smaller in diameter than the limit cylinder 9.

In this embodiment, the elastic support plate 12 is not provided to interfere with the lifting movement of the central tube 4, and therefore it must be retracted on the limit cylinder 9, so that the diameter needs to be relatively small.

Finally, the advantages of the jacking in this embodiment are summarized as follows.

First, the three of middle part body 4, arc 5 and U-shaped plate 6 "trinity" constitutes a two all usable parts for this jacking both can stably support circular steel pipe, can stably support square pipe such as I-steel, C shaped steel again, has improved the commonality of this jacking greatly.

And the second and the third-in-one parts are sleeved on the limiting cylinder 9 in a relatively tight thread joint manner, so that the jacking action of the parts is more stable and is not easy to deflect.

Thirdly, the mode of replacing the jacking end of the three-in-one component is relatively simple and convenient, and the three-in-one component is only spliced with the limiting cylinder 9, so that the components are directly taken down and then are vertically exchanged.

Fourth, the actual effective length of the jacking can be adjusted by the adjusting ring 8 and the supporting ring 2, and the rotation adjusting operation of the adjusting ring and the supporting ring is very convenient.

Fifth, the elastic support plate 12 also makes the jacking have a third use state, namely the three-in-one component is not used, and the elastic support plate 12 is matched with the support ring 2, so that a certain emergency and temporary use effect can be ensured.

Sixth, the adjusting ring 8 is not easy to fall off on the stud 1.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
