Abstract
The utility model discloses a kind of protective covers for steel bonding anchor bolt end, including sheet metal cover, built-in nut, the cavity for storing steel bonding glue.It is described to enclose bolt end for affixing steel plate reinforcement anchor bolt end protective cover of rotor, bolt corrosion and relaxation are prevented, keeps bolt stronger, not easily to fall off.
Description
Technical field
The utility model relates to the equipment that bridge strengthening construction uses, and protect more specifically to a kind of anchor bolt end
Cover.
Background technique
Bridge strengthening construction is often used affixing steel plate reinforcement method, and one of steel sticking method need to be anchored with bolt, often
Rule construction technology bolt end is chronically exposed in air, and nut for years may corrode, relaxes or fall off, and then is influenced
Steel plate stress causes steel plate to come to nothing or cannot have an adverse effect to structure, while nut is fallen very with structural coordination stress
Pedestrian, vehicle etc. below to possible hit bridge, there are security risks.
Utility model content
To solve existing steel bonding bolt end etching problem, the utility model provides a kind of affixing steel plate reinforcement anchor bolt end
Portion's protective cover prevents screw end head, nut corrosion and nut from falling off, it is ensured that bolt fastness.
To solve the above problems, the utility model adopts the following technical solution:
A kind of affixing steel plate reinforcement anchor bolt end protective cover of rotor, including sheet metal cover, built-in nut, the built-in nut welding
Inside the sheet metal cover, it is connected, the one side that the built-in nut is not connect with the sheet metal cover to the thin steel
There are a cavitys for plate cover opening.
Preferably, the inverted u-shaped shape of the sheet metal cover section or generally shape for hat cover.
Preferably, the cover wall height of the sheet metal cover is 2~3 times of the built-in nut height.
Preferably, the sheet metal cover with a thickness of 0.3~2mm.
Preferably, cavity is filled up with steel bonding glue when in use.
Preferably, it is in regular hexagon or square that the cover wall of the sheet metal cover, which overlooks face,.
Compared with the existing technology, the beneficial effects of the utility model are as follows:
Sheet metal cover is that stainless steel has excellent stainless corrosion resistance, tightens the nut with anchor bolt afterwards by built-in nut
Dieback, effective protection bolt anchor end from wet by the rain and burnt by the sun, and steel bonding glue is filled in entire protective cover, is used for sealing bolt end
Portion, while connect protective cover closely with bolt has further completely cut off bolt anchoring end and has been oxidized and got rusty.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section of affixing steel plate reinforcement anchor bolt end protective cover of rotor
Fig. 2 a and Fig. 2 b are the vertical view face schematic diagram of two kinds of embodiments of affixing steel plate reinforcement anchor bolt end protective cover of rotor.
Fig. 3 is the working state schematic representation of affixing steel plate reinforcement anchor bolt end protective cover of rotor.
Wherein, each appended drawing reference are as follows: 1, sheet metal cover；2, built-in nut；3, cavity；11, cover wall；22, nut；33, steel
Plate；44, screw rod.
Specific embodiment
In the following, being described further in conjunction with specific embodiment to the utility model:
As shown in Figure 1, that show the specific structure of the preferred embodiment of the utility model, described in the utility model one
Kind affixing steel plate reinforcement anchor bolt end protective cover of rotor, including sheet metal cover, built-in nut, the built-in nut are welded in the thin steel
It inside plate cover, is connected, the one side that the built-in nut is not connect with the sheet metal cover is stayed to the sheet metal cover opening
There is a cavity.
In the present embodiment, sheet metal cover is 304 stainless steels of 0.3mm, the inverted u-shaped shape of section.
As shown in Figure 2 a, a kind of affixing steel plate reinforcement anchor bolt end protective cover of rotor described in the utility model connects built-in nut
One end it is small, one end of opening is big, and cover wall is integrally in segmented cone type.
As shown in Figure 2 b, in order to facilitate the installation of, cover wall can also be completely or partially fabricated to regular hexagon or square
(not shown).
In the present embodiment, sheet metal cover is 304 stainless steels of 0.5mm, and the height of cover wall is 3 times of built-in nut height,
Protective cover center is Chong Die with pitch.
As shown in figure 3, a kind of affixing steel plate reinforcement anchor bolt end protective cover of rotor described in the utility model, sheet metal cover is whole outer
Shape is in shape for hat shape, and sheet metal cover uses 304 stainless steels of 2mm, and the height of cover wall is 2 times of built-in nut height, in protective cover
The heart is Chong Die with pitch.
In the present embodiment, after the nut of anchor bolt is tightened against steel plate, the nut of built-in nut and anchor bolt is selected
Matched protective cover injects a certain amount of steel bonding glue into sheet metal cover, it is ensured that full steel bonding glue is filled in protective cover.Then it will protect
Shield is twisted in bolt end, and built-in nut tightens the nut dieback with anchor bolt afterwards, and sheet metal cover opening edge is bonded with steel plate, has
Effect protection affixing steel plate reinforcement anchor bolt end.
It will be apparent to those skilled in the art that can technical solution and design as described above, make various other phases
The change and deformation answered, and all these changes and deformation all should belong to the protection model of the utility model claims
Within enclosing.
