Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, specifically, relates to a kind of prestress wire stretching end safeguard structure that is applied to bridge construction.
Background technology
Steel strand are one of basic tools very commonly used in various project constructions, one of its Main Function is by two equipment tensions, and in the termination of steel strand, for the ease of steel strand are fixed, usually use a ground tackle that the termination of steel strand is fixed, afterwards ground tackle is fixed on other equipment, so just very convenient in operation, and can improve tension effects.
But a lot of project construction cycles are long, construction environment is severe, and severe external environment is easy to make steel strand to get rusty, make the steel strand of tensioning to become slack.Such as: the factors such as moistening air, low temperature, difference variation all are easy to cause that the tensioning state of steel strand changes.And the tensioning state of steel strand changes, be to get rusty in the steel strand termination in essence, or being connected between steel strand termination and ground tackle become lax.The generation of this phenomenon, not only easily have a negative impact to project construction, but also easily cause the generation of security incident, therefore, must avoid.
The utility model content
The purpose of this utility model is to provide a kind of prestress wire stretching end safeguard structure that is applied to bridge construction, mainly solves the problem that easily badly get rusty because of construction environment in the steel strand termination and rate of tension becomes lax existed in prior art.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Be applied to the prestress wire stretching end safeguard structure of bridge construction, comprise that middle part offers through hole for the fixing anchor plate of steel strand tension end, and with this anchor plate, match the complete totally enclosed seal closure of steel strand tension end, sealing cover and described anchor plate are bolted connection.
Further, described seal closure comprises inner hollow and the cover body of bottom surface opening, and is arranged on the connector on the cover body bottom opening, and this connector is fastenedly connected by bolt and described anchor plate.
For the ease of realizing being connected of connector and anchor plate, the utility model provides following two schemes:
(1) described connector is annular, is distributed with equably at least two bolts hole on it, and its interior circular diameter is less than or equal to the bottom surface opening diameter of described cover body.In addition, between described connector and anchor plate, be provided with the seal gasket that shape is identical with connector, to improve the sealing between seal closure and anchor plate.
(2) described connector is locking journal stirrup, is at least two, is uniformly distributed on the opening with the cover body bottom surface, and offers bolt hole on each locking journal stirrup.Same, be provided with seal gasket between described cover body bottom surface, connector soffit and anchor plate, to improve the sealing between seal closure and anchor plate.
Further, for ease of producing, described cover body and connector are structure as a whole.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model is simple in structure, easy to operate, with low cost, and practical value is high;
(2) the utility model utilizes seal closure and anchor plate cooperation that the steel strand tension end is sealed fully, can effectively reduce the impact of external environment on the steel strand tension end, thus solve the steel strand tension end existed in prior art easily be subject to environmental change and become get rusty, lax problem;
(3) the utility model is used bolton seal closure and anchor plate, both easily installs, and also is convenient to dismounting, for construction in later period, maintenance provide great convenience.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The right view that Fig. 2 is embodiment 1.
The right view that Fig. 3 is embodiment 2.
In above-mentioned accompanying drawing, the component names that Reference numeral is corresponding is as follows:
The 1-anchor plate, 2-bolt, 3-cover body, 4-connector, 5-seal gasket, 6-ground tackle.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment 1
As shown in Figure 1 and Figure 2, the prestress wire stretching end safeguard structure that is applied to bridge construction that the utility model provides, mainly comprise seal closure and anchor plate 1.Wherein, seal closure consists of cover body 3 and connector 4, and both are one-body molded.Be provided with seal gasket 5 between connector 4 soffits and anchor plate 1.In the present embodiment, the hollow cavity that cover body 3 is the bottom surface opening, and its bottom surface is circular, and connector 4 is positioned on cover body 3 bottom surface openings, and around cover body one week.So, 5 of seal gaskets are annular, and its external diameter is less than the external diameter of connector, and its internal diameter also is less than the internal diameter of connector.
Anchor plate is selected shape, size arbitrarily according to circumstances, and still, no matter what shape anchor plate is, its surface size should be greater than connector, if: anchor plate is circular, and its diameter should be greater than the connector diameter; If anchor plate is rectangle, its wide diameter that should be greater than connector.
Because the soffit of connector is a plane, therefore, the Ye Wei plane, upper and lower bottom surface of seal gasket, thus good coordinating formed with connector and anchor plate, make sealing effectiveness reach best.
In addition, week at connector is upwards offered four bolts hole equably, correspondingly, also offer four bolts hole on anchor plate, utilize bolt 2 to realize being fastenedly connected between connector 4 and anchor plate 1, so not only easy for installation, interim overhaul, safeguard, the later stage dismounting is convenient too, has very high practical value.
During installation, first the steel strand tension end is passed from the middle part perforate of anchor plate, then with ground tackle 6, the termination of steel strand tension end is fixed, then the bolt hole of seal gasket and connector is alignd with the bolt hole on anchor plate, finally get final product by bolton.Because cover body inside is empty; because ground tackle is protected in its inside; enter and seal gasket can effectively completely cut off outside air, so can effectively stop the impact of external environment on ground tackle and the steel strand tension end of cover body inside, make ground tackle and steel strand tension end remain tensioning state.Need only unload bolt during dismounting, take off seal closure and get final product, very convenient.
As shown in Figure 3, the difference of the present embodiment and embodiment 1 is, the locking journal stirrup of connector 4 employing, and totally four, be uniformly distributed in cover body 3 bottom surface surroundings, seal gasket 5 is positioned at the cover body bottom surface, shape, large all identical with the cover body bottom surface.Certainly, if consider from the sealing effectiveness angle, seal gasket can be designed to the global shape of cover body bottom surface combined connecting component, so better.
Other structures of the present embodiment are identical with embodiment 1, do not repeat them here.
Above embodiment is only preferred embodiment of the present utility model; it is not the restriction to the utility model protection domain; in every case adopt design principle of the present utility model, and the non-creativeness that the utility model is carried out conversion, protection domain of the present utility model all belonged to.
