Abstract

The utility model discloses a pier column for bent cap construction, which comprises a column body. An anchor ear is mounted at the upper part of the column body; geotextile or rubber is arranged between the anchor ear and the column body; connection plates with a thickness equal to or greater than 5mm are arranged at two ends of the anchor ear; I-shaped steel is in lap joint on the connection plates; and preferably, joint bolts on the anchor ear are arranged in two lines vertically. The pier column has the advantages of strong construction maneuverability, relatively low requirements on foundation, low consumption of support steel pipes and greatly reduced cost, does not influence road transportation and river channel navigation, and facilitates quick and civilized construction.

Description

A kind of pier stud that is used for the bent cap construction

Technical field

The utility model relates to a kind of structure of setting up or assembling bridge that is exclusively used in, and specifically, relates to a kind of pier stud that is used for the bent cap construction in the bridge erection without scaffolding.

Background technology

At present, as the development of the bridge construction of highway construction important component part rapidly, on ordinary highway and the high-grade highway in, foot bridge, overpass bridge, various informative, bent cap applies and is that ingredient important in the bridge, its job practices also are tending towards variation.

The full hall of the most employing frame construction of the cast bent cap construction in the tradition bridge construction, but the construction of support method has following limitation and defective: one, because the bridge pier column height is higher, therefore be that the support input amount of material is very big with steel pipe or timber, and set up with striking and also need to consume lot of manpower and material resources, if when needing to adjust the counterdie height owing to the pier stud height change, then inconvenience more; Its two, for having relatively high expectations of bearing capacity of foundation soil, need carry out preliminary treatment such as compacting, fluid concrete to the basis, in case handle accidentally, will cause that support is whole to sink, have a strong impact on the bent cap quality; Its three, the physical features of pier stud bottom surface often has situations such as physical features injustice, next-door neighbour stream, construction plant are narrow and small, then is difficult to even can't constructs this moment; Its four because the support bottom is impassable, taken a lot of ground handling faces, both dangerous, also can influence execution control.

The utility model content

It is bigger that the technical problems to be solved in the utility model provides a kind of bearing load, and set up the pier stud that is used for the bent cap construction with striking easily, it can overcome the drawback that the support method is subjected to landform and environmental limitations, has saved engineering time and construction cost simultaneously greatly.

In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:

A kind of pier stud that is used for the bent cap construction comprises cylinder, and described cylinder top is equipped with anchor ear, is lined with pad between described anchor ear and the described cylinder, and described anchor ear two ends are provided with junction plate, are erected with " worker " word steel on the described junction plate.

The thickness of described junction plate is at least 5mm.

Connecting bolt on the described anchor ear sets up two rows separately on vertical.

Described pad is geotextiles or rubber.

The beneficial effects of the utility model are:

(1) the utility model need not the ground stabilization processing, and former ground only needs suitably to handle and gets final product for scaffold building, and ground does not need complicated consolidation process such as compacting and fluid concrete.

(2) adopt the utility model, still can pass through in bent cap construction middle and lower part, do not take up an area of the face work plane, is convenient to execution control.

(3) full framing of the prior art will consume a large amount of tube materials and sets up support bracket, and the utility model utilizes anchor ear fastening, and " worker " word steel supports, and need not to set up the carrying steel pipe support.

(4) the utility model formwork is convenient, turnover is convenient and swift, full hall frame will be handled from ground stabilization, up set up from level to level again, spend a large amount of time and manpower, and the utility model only needs two " worker " word steel and several anchor ear are removed, easy construction, turnover is fast, moves also convenient many by contrast.

(5) construction of the present utility model is workable, can not influence the navigation of road traffic and river course, helps fast and civilized construction.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is a lateral view of the present utility model;

Fig. 3 is the structural representation of the utility model anchor ear.

Among the figure: 1: bent cap; 2: " worker " word steel; 3: connecting bolt; 4: anchor ear; 5: cylinder; 6: junction plate.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

The utility model is to utilize anchor ear method principle, anchor ear 4 is installed and is made it and pier stud 5 clamps and produces maximum static friction forces at the suitable position of pier stud 5, overcome the weight of temporory structure and bent cap 1, it is little to be particularly useful for 1 time bearing capacity of foundation soil of cast-in-place bent cap 1 waterborne or bent cap, bent cap 1 is highly big, bent cap 1 deadweight is little, the situation that working load is little.

As depicted in figs. 1 and 2, the concrete structure of the technical program is, a kind of pier stud that is used for the bent cap construction comprises cylinder 5, and described cylinder 5 tops are equipped with anchor ear 4.Anchor ear 4 both sides are provided with junction plate 6, and as shown in Figure 3, junction plate 6 is provided with connecting bolt 3, are used for two semicircle assembly butt joints of anchor ear 4 fixing.Be erected with " worker " word steel 2 between two pier studs, " worker " word steel 2 is erected at above the junction plate 6, is used to lay bent cap 1 template.

The installation site of anchor ear 4 is at the counter downwards thickness of bent cap 1 soffit formwork and the thickness of " worker " word steel 2 of removing of 1 end of bent cap absolute altitude, is defined as the top mark height of anchor ear, thereby determines the position of anchor ear 4 on cylinder 5.

Must be closely connected when anchor ear 4 is installed on the cylinder 5 with cylinder 5, because the impossible absolute circle in pier stud cylinder 5 cross sections, each cylinder 5 out-of-roundness is different, therefore for adapting to the cylinder 5 of various out-of-roundness, the hoop body of anchor ear 4 should employing not established the flexible band body that hoop is put more energy into.Generally between anchor ear 4 and cylinder 5, fill up with geotextiles or rubber, to increase frictional force.

The pretension of connecting bolt 3 must be able to guarantee that the frictional force of 5 of anchor ear 4 and cylinders can transmit load reliably on the anchor ear 4.Cause the steel plate hoop slippage for the prevention working load is excessive, should adopt 5mm or greater than the junction plate 6 of 5mm thickness, and the connecting bolt on the junction plate 63 is arranged to two rows on vertically, employing high-strength bolt and double nut are tightened anchor ear.

During use, bent cap 1 template of setting up fixes, and also will set up the construction safety passage of concreting simultaneously, guarantees constructor's safety, adopts crane to lift concreting, and arranges the special messenger to be responsible for the inspection of bent cap template.

Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.
