Abstract
The utility model discloses a truss for supporting form. In cast-in-place concrete construction, the supporting form with cast-in-place structure which has larger span usually adopts that the whole room is supported with the supporting forms. The supporting material and the working time are wasted, and the difficulty of the construction is large. The truss for supporting form is compose of a cross rod, a vertical rod, an inclined rod and a steel cable. One end of the vertical rod is vertically fixed on the cross rod, and the other end is fixedly connected with one end of the inclined rod. The other end of the inclined rod is fixed on the cross rod, and the steel cable is connected with both ends of the cross rod around the connecting point of the vertical rod and the inclined rod. When the utility model is used, the cross rod is placed on supporters of both ends, and the concrete can be cast in plate after a form plate is placed. The material and the labor are saved, and the utility model is suitable for the construction of buildings, bridges, etc.
Description
The utility model belongs to the house, equipment is used in the bridge construction construction, refers in particular to a kind of formwork truss.
In building cast-in-situ concrete constructions such as house, bridge at present,, generally use the full framing support shuttering for the cast-in-place knot formwork of the bigger steel bar concrete of span, on template, put reinforcing bar, cast-in-situ concrete, this full framing has following shortcoming: 1, frame material requirement is big, the construction cost height; 2, in the construction plant of crossing over road, melt pit, groove, to set up full hall frame ground is required height, the difficulty of construction is big; When 3, crossing over road, block the traffic the influence construction.
The purpose of this utility model is to provide a kind of formwork truss, and this formwork truss can set up conveniently when complicated grounds such as leap melt pit, groove; When crossing over road, do not influence traffic, construction is easy, and frame material requirement is few, and the engineering time is short, and cost greatly reduces.
The purpose of this utility model is to realize like this, form the formwork truss by cross bar, left and right sides vertical rod, left and right sides brace, cable wire, vertical rod one end in the left and right sides is vertically fixed on the cross bar, the other end is connected with an end of left and right sides brace respectively, the other end of left and right sides brace interconnects and is fixed on the cross bar, and cable wire is walked around left and right sides vertical rod and is connected with the two ends of cross bar respectively with the interface point of left and right sides brace, the two ends of cable wire.There is screw thread at the two ends of cable wire, are tightened on the cross bar with double nut.During use, the cross bar of truss is seated on the two end supports thing, puts template above and get final product cast-in-situ steel reinforced concrete.
The span length of this formwork truss can reach 8 meters, two formwork truss connect can reach 16 meters, only needs to take a scaffold sub-truss in the junction and gets final product, and can save a large amount of frame material, and rolling of scaffold ground (about 1 meter) is easy to, construction is simple, has shortened man-hour, and construction cost is low, when crossing over road, space, scaffold both sides is big, and the P Passable vehicle can not influence traffic.
The utility model is described in further detail below in conjunction with accompanying drawing
Fig. 1 is a formwork trussed construction schematic diagram
Fig. 2 is another structural representation of formwork truss
Fig. 3 is the on-the-spot schematic diagram that uses of formwork truss construction
In Fig. 1, Fig. 2, form the formwork truss by cross bar (3), left and right sides vertical rod (8) (6), left and right sides brace (4) (5), cable wire (7).Left and right sides vertical rod (8) (6) one ends are vertically fixed on the cross bar (3), the other end is fixedlyed connected with an end of left and right sides brace (4) (5) respectively, the other end of left and right sides brace (4) (5) interconnects and is fixed on the cross bar (3), cross bar (3), left and right sides vertical rod (8) (6), left and right sides brace (4) (5) is formed two symmetrical triangles, cable wire (7) is walked around the interface point (9) (18) of left and right sides vertical rod (8) (6) and left and right sides brace (4) (5), the two ends of cable wire (7) are connected with the two ends of cross bar (3) respectively, at the two ends of cable wire (7) weldable steel bars (10), one end of steel pole (10) has screw thread, strengthening backing plate (2) is arranged on the cross bar (3), steel pole (10) passes cross bar (3), strengthen backing plate (2), tighten with double nut (1), cable wire (7) is tightened, until reaching the intensity that needs.
One backing plate (11) can be set between one port of formwork truss left and right sides brace (4) (5), and left and right sides brace (4) (5) connects into integral body and affixed with cross bar (3) with backing plate (11).Backing plate (11) can strengthen the supporting surface of left and right sides brace (4) (5) to cross bar (3), increases support degree.Steel concrete is pressed in the weight in the middle of the cross bar (3), is delivered to cable wire (7) through left and right sides vertical rod (8) (6), left and right sides brace (4) (5), is delivered to cross bar (3) two ends again, and the support strength of cross bar (3) is strengthened.
Referring to Fig. 3, the house, when construct in building sites such as bridge, the two ends of formwork truss cross bar (3) are placed on the stent material, be placed on the bridge stone steps (15) as an end, one end is placed on the middle scaffold (17) of bridge, and the span length of two formwork truss (12) can reach 16 meters, and the middle scaffold (17) that only need take about one 1 meter, the both sides of scaffold (17) are left than large space, promptly saved the frame material of 60-70%, (as certain bridge, access bridge amounts to 36 and strides, bridge floor is wide 25.5 meters, 15 meters of spans, ground to bridge floor is up to 13 meters, adopts this truss construction to compare with full hall frame formwork, saves 700,000 yuan of operating expenses), also saved man-hour, be convenient to vehicle pass-through again; Under the relatively poor situation of state of ground, the ground (16) of rolling support scaffolding is also easy.Template (13) is seated on the cross bar (3), goes up cast-in-situ steel reinforced concrete (14) in template (13).And the formwork truss can use tens times repeatedly.Cross bar (3), left and right sides vertical rod (8) (6), left and right sides brace (4) (5) can be used the reinforced frame material, also can use the China fir wood strip, 6 meters stride China fir tail footpath, footpath and should be not less than 110mm, 8 meters stride its tail footpath, footpath and should be not less than 130mm.This formwork truss can be made in advance, also can make according to on-the-spot span temporarily, determines number and the density that the formwork truss is laterally put according to cast-in-situ concrete width, thickness, and this formwork truss is applicable to building operations such as house, bridge.
