Description
Technical field
The utility model relates to a kind of bracing or strutting arrangement that is mainly used on the bridge pier column, is a kind of pier column hoop device specifically.
Background technology
In bridge construction process, after the construction of having finished bridge pier column, when carrying out the bent cap construction, need set up interim fastening earlier, so that the template of bent cap is supported temporarily.At present, the interim fastening of bent cap construction has following several:
1, utilizes frame pipe, fastener etc., on the whole construction face, set up full framing, form the interim casting platform of concreting beam.This interim fastening has following defective: the basis of the full framing that 1) must harden when construction, the support ground is carried out layering handle, for the soft base of bearing capacity difference, if deal with improperly, will cause the differential settlement of support ground, and then have influence on the construction quality of bent cap; 2) the ground processing is long with the erection construction cycle of support, and construction speed is slower, and is time-consuming, and needs a large amount of frame pipes, fastener etc., and cost is also higher; 3) require the job site must not have obstruction,, then can't use this kind fastening for the job site that obstruction is arranged; 4) supporting capacity of this full framing is limited.
2, on the bridge pier post of having finished, utilize the mode of reserving hole or pre-buried steel structure, form the interim strong point, on the interim strong point, utilize Bei Leiliang or universal rod body to set up the interim casting platform of concreting beam.The defective of this kind mode is: need be on the bridge pier post reserving hole or pre-buried steel structure, cause bridge pier post construction inconvenience, the steel form of bridge pier needs opening; And finish at bridge construction, still can on bridge pier, leave a trace after the pre-buried steel structural member cuts off, thereby influence the overall appearance of bridge.
3, for comparatively general cylindrical pier stud, the someone adopts the supporting way of anchor ear as the bent cap construction at present.The inner surface of this anchor ear is the circle that corresponds essentially to this pier stud, after being fixed on the pier stud, the inner surface of anchor ear and the external surface of pier stud are fitted, and under the fastening effect of the securing member on the anchor ear, anchor ear applies normal pressure to pier stud, make between anchor ear inner surface and the pier stud external surface and form frictional force, thereby can support temporarily the construction of bent cap.This mode is because structure is light, processing and fabricating is simple, and low cost and other advantages is widely used in the bridge construction in recent years.Have following defective but the circular anchor ear of this kind supports: 1) since total inner surface all as the rubbing surface that contacts with pier stud, the shape of the inner surface of this anchor ear need have higher processing precision corresponding to the external surface of pier stud, could guarantee fitting tightly between the anchor ear inner surface and pier stud external surface in use, form frictional force.Because machining accuracy, the inner surface of anchor ear often is difficult to fit fully with the external surface of pier stud, causes actual fitting tightly and effective rubbing surface of forming is smaller, thereby makes the frictional force of actual formation less, has reduced the actual carrying capacity of anchor ear.2) for special-shaped pier stud, as eight prismatic pier studs, this circle anchor ear is with inapplicable.Even the inner surface correspondence is processed into eight prismatics and since pier stud edges and corners holding capacity a little less than, may cause damage to the outward appearance of pier stud.
Therefore, be necessary to provide a kind of novel pier column hoop device, overcome the defective of the interim fastening in the above-mentioned existing bridge construction.
Summary of the invention

In the utility model, described rubbing surface circumferentially evenly distributes along the housing medial surface.
In the utility model, on described rubbing surface, can be covered with the individual layer geotextiles, increasing friction factor, and the external surface of pier stud is played the certain protection effect.
In the utility model, described rubbing surface is plane or arcwall face.
In the utility model, described housing can be formed by connecting by the framework more than two sections or two sections.Described framework more than two sections or two sections can link together by flange and securing member.
In the utility model, described housing can be polygon, circle, ellipse etc.
As a concrete optional embodiment, described housing is square.
In this example, preferably, be equipped with a rubbing surface on each medial surface of described square frame.Described rubbing surface preferably is arranged on the centre position of each medial surface of housing.
Described square frame is assembled by two " L " shape frameworks.Docking location correspondence two " L " shape frameworks is provided with flange, and these two frameworks by securing member in the flange fixed-site together.
In the utility model, described pier column hoop device can be further by stacked forming about two or more the anchor ear monomer.Like this, can reduce the height of anchor ear monomer, slacken its guide effect, improve self-locking property, improve supporting capacity.
Utilize said structure of the present utility model, pier column hoop device of the present utility model is owing to be provided with two or more the rubbing surface that protrudes in medial surface on the medial surface of housing, in the time of on being installed on pier stud, this rubbing surface that protrudes in medial surface can effectively be fitted with the outer surfaces of pier stud, produce frictional force, play a supporting role.Like this owing to be to form frictional force with the external surface applying of pier stud by the rubbing surface that protrudes in medial surface, therefore when making this anchor ear, only need guarantee consistent the getting final product of outer surfaces shape of this rubbing surface and pier stud, the medial surface of anchor ear does not then need the requirement of machining accuracy, thereby reduce the requirement on machining accuracy of anchor ear, rubbing surface also more can be effectively and the external surface of pier stud fit, improve supporting capacity.In addition, as eight prismatic pier studs, rubbing surface can be avoided the corner angle position and be provided with for the special-shaped pier stud that corner angle are arranged, thereby makes corner angle position easy damaged not in use, has guaranteed the attractive in appearance of pier stud profile.
