Description
Technical field
The present invention relates to a kind of staircase shaping formwork support.
Background technology
In the stair work progress, at first need to set up the stair formwork erecting system, and then carry out the pouring concrete of stair, the stair formwork erecting system plays the effect of supporting with typing in whole stair casting process, but all there is following shortcoming in existing stair formwork erecting system:
1, complicated construction technique, the material category of use is many;
2, the formwork system fastness is poor, receives easily cast power and be out of shape poor safety performance in casting process;
3, the concrete Forming Quality of stair is poor, and physical dimension is accurate not;
4, because complex structure so that the workman can not finely understand construction point in constructing operation, thereby affects construction speed;
5, spillage of material is large in the demolishing process of template, and stock utilization reduces.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, provide a kind of safe and simple, Forming Quality is high, the staircase shaping formwork support of accelerating construction progress, reduction spillage of material.
Purpose of the present invention is achieved through the following technical solutions: staircase shaping formwork support, mainly by at least two support bars that move towards to arrange and be positioned at the stair top along stair, and some stereotype plates that lean respectively on the stair riser consist of, be fixed together by anchorage bar between the described support bar and consist of the staircase shaping support, and the below of support bar is provided with the horizontal push rod corresponding with the 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 so that laterally forms between push rod, vertical push rod and the support bar and be more conducive to firm triangle.
Further, the present invention 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 nut is fixed on 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 arrange 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 invention has the beneficial effects as follows:
(1) construction technology was than originally greatly simplifying, and the material category 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 present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment:
Staircase shaping formwork support 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 consist of, 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 consists of the staircase shaping support, is fixed by fastening clip between support bar 2 and the anchorage bar 7; And the below of every support bar 2 is provided with the horizontal push rod 4 corresponding with 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, so that whole system has 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; For so that whole system has 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 so that laterally between push rod 4, vertical push rod 8 and the support bar 2 formation be more conducive to firm triangle.
Further, in the present embodiment, laterally push rod 4 is all perpendicular to the stereotype plate corresponding with its position 3, 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 that cost and material are made, 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 consist of 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, for so that flitch 5 in casting process, do not move along stair 1 riser direction because being subject to cast power, the present invention has also set up and has been used for the fixedly grapple 6 of 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 produces at first is applied to stereotype plate 3, pass to the horizontal push rod 4 that leans on stereotype plate 3 by stereotype plate 3, and then be applied on support bar 2 and the anchorage bar 7 formation staircase shaping supports, in actual stair casting process, the staircase shaping support 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 whole system under the effect of cast power and do not produce distortion.
As mentioned above, just can realize preferably the present invention.
