Abstract
The invention discloses a light anchorage structure, comprising a reinforced concrete pile body (1) embedded in a rock mass. The light anchorage structure is characterized in that the upper end of the reinforced concrete pile body (1) is provided with a reinforced concrete bearing platform (2), the upper end of the reinforced concrete bearing platform (2) is provided with two rib type wall bodies (3) which are symmetrically arranged, one side of each rib type wall body (3) is provided with an inclined plane (4), the inclined plane (4) is provided with multiple load distributing girders (5), and a steel strand (6) penetrates a gap between the two rib type wall bodies (3) to be fixedly connected with the distributing girders (5) by virtue of a prestress anchorage. The light anchorage structure disclosed by the invention has the advantages of simple structure, smart design, reasonable layout, small occupying space and low cost.
Description
Technical field
The present invention relates to a kind of arch bridge and tiltedly draw buckling and hanging system to use anchorage, particularly a kind of light-duty anchorage structure.
Background technology
When carrying out the construction of arch bridge; The system of buckling of tiltedly drawing of arch bridge needs a fixed point (being anchorage); Traditional method be water outpour a volumes, concrete that weight is bigger sticks together; Then steel strand are connected and are embedded on the fixture of concrete in sticking together, utilize stick together weight of concrete itself anchorage to be provided for Arch Bridge Construction.The anchorage of this gravity takes up room bigger, and cost is higher, and economy is relatively poor.Therefore need a kind of novel anchorage structure that can address the above problem now.
Summary of the invention
The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingeniously, rationally distributed, and light-duty anchorage structure little, with low cost takes up room.
Technical solution of the present invention is: a kind of light-duty anchorage structure; Comprise the steel concrete pile body 1 that is embedded in the rock mass; It is characterized in that: described steel concrete pile body 1 upper end is provided with steel concrete cushion cap 2; Steel concrete cushion cap 2 upper ends are provided with the fin-plate type wall body 3 of two symmetries, and a side of fin-plate type wall body 3 is provided with inclined-plane 4, and inclined-plane 4 is provided with a plurality of distribution beam 5; Steel strand 6 are fixedly connected with distribution beam 5 through prestressed anchor after passing two spaces between the fin-plate type wall body 3.
The present invention compares with prior art, has following advantage:
This kind of light-duty anchorage structure of form of structure, it is simple in structure, designs ingenious; Rationally distributed, it adopts the gravity concrete to stick together as anchorage to traditional arch bridge processing, defectives such as big, the cost height of taking up room; Design buried special construction in the rock stratum; Utilize relative smaller volume just can realize the function of anchorage, under the prerequisite of saving construction space, can also save cost.Therefore we can say that this light-duty anchorage structure has possessed multiple advantage, be particularly suitable for applying in the art that its market prospects are very wide.
Description of drawings
Fig. 1 is the working state figure of the embodiment of the invention.
Fig. 2 is the vertical view of embodiment of the invention fin-plate type wall body part.
The specific embodiment
Below with the accompanying drawings specific embodiment of the present invention.Like Fig. 1, shown in Figure 2: a kind of light-duty anchorage structure; Comprise that this steel concrete pile body 1 is embedded in rock stratum or underground, is provided with steel concrete cushion cap 2 in steel concrete pile body 1 upper end as the steel concrete pile body 1 on basis; Steel concrete cushion cap 2 is provided with two fin-plate type wall bodies 3; These two fin-plate type wall bodies 3 are symmetrical set, and all are provided with inclined-plane 4 in a side of each fin-plate type wall body 3, and inclined-plane 4 is provided with a plurality of distribution beam 5; Steel strand 6 pass two spaces between the fin-plate type wall body 3, and its terminal prestressed anchor that passes through is fixedly connected with distribution beam 5.
The course of work of the light-duty anchorage structure of the embodiment of the invention is following: at first steel concrete pile body 1 is embedded in rock stratum or underground in advance; After letting steel strand 6 pass two spaces between the fin-plate type wall body 3 then; Be connected through prestressed anchor with distribution beam 5, realize the fixing of steel strand 6 ground surface end.
Because some gos deep into rock stratum or underground this anchorage structure; Being equivalent to this anchorage structure and bottom surface is combined as a whole securely; The gravity that not only relies on this structure itself is that arch bridge tiltedly draws the button extension that pulling force is provided; But pulling force is directly passed to ground, this particular design can let this device not need too huge volume just can realize the anchorage effect.
Claims (1)
1. light-duty anchorage structure; Comprise the steel concrete pile body (1) that is embedded in the rock mass; It is characterized in that: described steel concrete pile body (1) upper end is provided with steel concrete cushion cap (2); Steel concrete cushion cap (2) upper end is provided with the fin-plate type wall body (3) of two symmetries, and a side of fin-plate type wall body (3) is provided with inclined-plane (4), and inclined-plane (4) are provided with a plurality of distribution beam (5); After steel strand (6) pass the space between two fin-plate type wall bodies (3), be fixedly connected with distribution beam (5) through prestressed anchor.
