Description

Stair typing support for shuttering

Technical field

The utility model relates to a kind of stair typing support for shuttering.

Background technology

In the stair work progress, at first need to set up the stair formwork system, and then carry out the concrete pouring of stair, the stair formwork system plays the effect of supporting with typing in whole stair casting process, but all there is following shortcoming in existing stair formwork system:

1, construction technology complexity, the total class of the material of use is many;

2, the formwork system fastness is poor, receives cast power easily and be out of shape poor safety performance in the process of building;

3, the concrete Forming Quality of stair is poor, and physical dimension is accurate inadequately;

4, owing to complex structure, make the workman in constructing operation, can not finely understand construction point, thereby influence construction speed;

5, spillage of material is big in the demolishing process of template, and stock utilization reduces.

The utility model content

The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, provide a kind of safe and simple, Forming Quality is high, the stair of accelerating construction progress, reduction spillage of material typing support for shuttering.

The purpose of this utility model is achieved through the following technical solutions: stair typing support for shuttering, mainly by at least two support bars that move towards to be provided with and to be positioned at the stair top along stair, and some stereotype plates that lean respectively on the stair riser constitute, be fixed together by anchorage bar between the described support bar and constitute the stair setting bracket, and the below of support bar is provided with and the corresponding horizontal push rod in stereotype plate position, one end of described horizontal push rod is fixed on the support bar, its other end leans on stereotype plate, in order to improve steadiness, should guarantee as far as possible during installation that horizontal push rod is perpendicular to the stair riser.

Further, the upper end of described horizontal push rod all is equipped with vertical push rod, is provided with flitch along the stair riser between vertical push rod and the stereotype plate, in order to improve steadiness, should guarantee as far as possible during installation that vertical push rod is perpendicular to horizontal push rod; Described flitch is preferential to adopt 50 * 100 flitches, but is not limited to 50 * 100 flitches, also can be according to practice of construction demand otherwise designed.

As a kind of preferred arrangement of vertical push rod, an end of described vertical push rod is fixed on the horizontal push rod, and its other end is fixed on the support bar, thereby making to form between horizontal push rod, vertical push rod and the support bar is more conducive to firm triangle.

Further, the utility model also comprises grapple, and described grapple two ends are separately fixed on flitch and the vertical push rod.

As a kind of optimal way of grapple, an end of described grapple is the grappling fixture that is hook-shaped, and its other end is equipped with nut, and the screw rod that position and size and nut are complementary is installed on the vertical push rod; Described grappling fixture is fixed on the flitch, and fixed by nut is at screw rod.

In order to guarantee the steadiness of whole support system, be fixed together by fastening clip between described anchorage bar and the support bar, and anchorage bar should be provided with three at least.

It is the laminate of 17mm that above-mentioned stereotype plate preferentially adopts thickness, but is not limited to this, also can select separately according to the practice of construction demand.

In sum, the beneficial effects of the utility model are:

(1) construction technology was than originally greatly simplifying, and the total class of the material of use reduces;

(2) template system is more firm, and is not yielding in casting process, thereby safer;

(3) the concrete Forming Quality of stair improves greatly, and physical dimension is more accurate;

(4) workman is convenient understandable in constructing operation, accelerating construction progress;

(5) spillage of material is little in the demolishing process of template, has improved the utilization rate of material.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.

Embodiment:

Stair typing support for shuttering shown in Fig. 1,2,3 and 4, mainly by move towards setting along stair 1 and being positioned at two support bars 2 of stair 1 top and the some stereotype plates 3 that lean respectively on stair 1 riser constitute, the number of the number of stereotype plate 3 and stair 1 riser is identical and corresponding one by one, according to the principle of practice of construction demand and saving cost, stereotype plate 3 employing thickness are the laminate of 17mm in the present embodiment.

Being fixed together by three anchorage bars 7 between two support bars 2 constitutes the stair setting bracket, fixes by fastening clip between support bar 2 and the anchorage bar 7; And the below of every support bar 2 is provided with and the corresponding horizontal push rod 4 in stereotype plate 3 positions, and an end of described horizontal push rod 4 is fixed on the support bar 2, and its other end leans on stereotype plate 3;

For stereotype plate 3 can better be resisted its lateral pressure in the stair casting process, make whole system have better steadiness, in the upper end of each horizontal push rod 4 vertical push rod 8 is installed all, be provided with flitch 5 along stair 1 riser between vertical push rod 8 and the stereotype plate 3, according to the principle of practice of construction demand and saving cost, flitch 5 adopts 50 * 100 flitches in the present embodiment; In order to make whole system have better steadiness, an end of described vertical push rod 8 is fixed on the horizontal push rod 4, and its other end is fixed on the support bar 2, thereby making to form between horizontal push rod 4, vertical push rod 8 and the support bar 2 is more conducive to firm triangle.

Further, in the present embodiment, laterally push rod 4 all perpendicular to the corresponding stereotype plate 3 in its position, laterally push rod 4 is also vertical with vertical push rod 8 mounted thereto, thereby strengthened the steadiness of whole system, not yielding in casting process, the stair Forming Quality improves greatly.

In the practice of construction process, consider the convenience of cost and material, laterally push rod 4 and vertical push rod 8 can weld together formation by two angle bar, 30 angle bar that to vertically place in the present embodiment and 30 angle bar of laterally placing weld together can constitute horizontal push rod 4 and vertical push rod 8, as shown in Figure 5.

Because flitch 5 is for directly being placed on the horizontal push rod 4, in order to make flitch 5 in casting process, not move along stair 1 riser direction because of being subjected to cast power, the utility model has also been set up the grapple 6 that is used for fixing flitch 5, as shown in Figure 6, one end of described grapple 6 is the grappling fixture 9 that is hook-shaped, its other end is equipped with nut 10, and the screw rod that position and size and nut 10 are complementary is installed on the vertical push rod 8; In work progress, grappling fixture 9 is fixed on the flitch 5, nut 10 is fixed on screw rod, thereby with flitch 5 being fixed on the vertical push rod 8 tightly, it can not be slided along stair 1 riser.

In the stair casting process, the cast power that cast is produced at first affacts stereotype plate 3, pass to the horizontal push rod 4 that leans on stereotype plate 3 by stereotype plate 3, and then affact on support bar 2 and the anchorage bar 7 formation stair setting brackets, in actual stair casting process, the stair setting bracket normally leans or is fixed on the fixed buildings such as flooring/metope and is stable state, thereby play the effect of supporting whole system and resist stair cast power, guaranteed that whole system is under the effect of cast power and do not produce distortion.

As mentioned above, just can realize the utility model preferably.
