Abstract
The utility model discloses a stretching device for V-shaped bridge pier construction with an external steel mold. The stretching device mainly comprises a steel moulding plate, a triangle supporting plate, a movable anchor box and a lifting jack, wherein a V-shaped bridge pier is covered with the steel moulding plate by horizontal pull rods; a round purlin is additionally arranged on the steel moulding plate; the triangle supporting plate is arranged between one side of the round purlin and the steel moulding plate; the movable anchor box is anchored on the other side of the round purlin; one side of the movable anchor box pushes against the lifting jack; and the triangle supporting plate, the round purlin, the movable anchor box and the lifting jack penetrate through the horizontal pull rods and are positioned on the same horizontal line. The stretching device has the benefits that the construction speed is increased in a V-shaped pier construction process; the construction cost is reduced; and damage to concrete and an effect on the appearance quality are avoided.
Description
Technical field
The utility model belongs to V-type Bridge Pier Construction technical field in the bridge engineering, relates in particular to a kind of tensioning equipment that utilizes the steel external mold to carry out the construction of bridge V pier.
Background technology
The common technology of opposing horizontal thrust all is to reserve stretching notch or steel anchor box is set outside concrete to carry out stretch-draw in V leg concrete in the bridge V-type Bridge Pier Construction at present.Many problems have appearred in these two kinds of methods in actual use, and the one, stretching force is too concentrated, may cause concrete cracking; The 2nd, too much notch or steel anchor box affect concrete overall appearance quality.
For addressing these problems existing treatment measures in the practice of construction:
1, the anti-reinforced mesh that collapses of colligation anticracking around stretching notch;
2, utilize pea gravel concreten to the stretching notch sealing off and covering anchorage;
3, cut off steel anchor box, the mending concrete external surface.
The shortcoming of above several all methods is expense material consuming time, increases difficulty of construction, improves construction cost, and concrete presentation quality is had certain influence.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of function that had both possessed prior art is provided, can save again cost, accelerate speed of application and not affect a kind of tensioning equipment that utilizes the steel external mold to carry out the construction of bridge V pier of Surface Quality of Concrete.
The purpose of this utility model is finished by following technical solution, it mainly is comprised of steel form, gusseted plate, mooring drag case, jack, described steel form is overlying on the bridge V pier by girt, have additional at this steel form and to enclose purlin, and this encloses between a side of purlin and steel form and is provided with the gusseted plate; Anchoring has the mooring drag case on the described opposite side that encloses purlin, and there is jack on the side top of this mooring drag case; This gusseted plate, enclose purlin, mooring drag case, jack on girt, and all be on the same level line.
As preferably, the described purlin that encloses is that the Two bors d's oeuveres channel-section steel consists of, and encloses the purlin periphery at this and is loaded with successively elongated stiffener, stiffener, elongated web, and the inside of enclosing purlin is provided with encloses the purlin anchor clamps, and this side of enclosing purlin is connected with removable insole pieces.
The beneficial effects of the utility model are: in V pier work progress, accelerate speed of application, reducing construction cost has been avoided the impact on concrete damage and presentation quality;
1, sets up at punching block and enclose purlin, can finish in the processing and making process of punching block ground in early stage, do not need aloft operation of later stage, compare and in the V pier, reserve notch or concrete peripheral hardware steel anchor box more makes things convenient for, saves time, safety;
2, enclose the material that purlin adopts and comprise shaped steel and iron plate, all can recycle, compare reinforcing bar, the ground tackle that notch needs is set, cost is lower;
3, enclose purlin be arranged so that horizontal stretch-draw the time, concrete is stressed evenly, not the easy damaged concrete;
4, adopt through rolling screw-thread steel as girt, only need the less steel pipe of diameter as the sleeve pipe concrete of nuzzling, the notch that the phase specific area is relatively large is more easily repaired, and does not affect outward appearance.
Description of drawings
Fig. 1 is the peripheral purlin arrangement of steel form of the present utility model schematic diagram.
Fig. 2 is the A place structure for amplifying schematic diagram of Fig. 1.
Fig. 3 is the purlin structural representation that encloses of the present utility model.
Label in the accompanying drawing is respectively: 1, steel form, 2, gusseted plate, 3, the mooring drag case, 4, jack, 5, girt, 6, bridge V pier, 7, enclose purlin, 71, elongated stiffener, 72, stiffener, 73, elongated web, 74, enclose the purlin anchor clamps, 75, removable insole pieces.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in accompanying drawing 1 to 3, the utility model mainly is comprised of steel form 1, gusseted plate 2, mooring drag case 3, jack 4, described steel form 1 is overlying on the bridge V pier 6 by girt 5, have additional at this steel form 1 and to enclose purlin 7, and this side and 1 of steel form of enclosing purlin 7 are provided with gusseted plate 2; Anchoring has mooring drag case 3 on the described opposite side that encloses purlin 7, and there is jack 4 on the side top of this mooring drag case 3; This gusseted plate 2, enclose purlin 7, mooring drag case 3, jack 4 on girt 5, and all be on the same level line.The described purlin 7 that encloses encloses purlin 7 peripheries at this and is loaded with successively elongated stiffener 71, stiffener 72, elongated web 73 for the Two bors d's oeuveres channel-section steel consists of, and the inside of enclosing purlin 7 is provided with encloses purlin anchor clamps 74, and this side of enclosing purlin 7 is connected with removable insole pieces 75.
In steel form 1 process of V pier, enclose purlin 7 in the design attitude increase.When purlin 7 is enclosed in setting, need gusseted plate 2 to be set enclosing 1 of purlin 7 and steel form, so that enclose purlin 7 levels, according to selected gusseted plate 2 thickness of design stretching force and distribute spacing.Enclose purlin 7 and can adopt the Two bors d's oeuveres channel-section steel, be guaranteed strength, can increase elongated web 73 and stiffener 72 at channel-section steel 7.
The practice of construction process is as follows:
1, after steel form 1 installation, girt 5 is installed directly, is noted packaging in advance sleeve pipe;
2, pretension girt 5 before the concreting, make concreting complete after, girt 5 keeps levels;
3, build after, after concrete reaches designing requirement, carry out horizontal stretch-draw.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
