Description

Tooth form bolt sleeve

Technical field

The utility model relates to tooth form bolt sleeves, belong to bolt sleeve technical field.

Background technique

Bolt sleeve one end of the prior art is buried end, and the other end is bolted end, and the work of stressed member is played at buried end With, and the bottom at buried end is all planar structure, but since bolt sleeve is without other stressed members, lead to spiral shell in use process It is not big enough that bolt covers stress intensity.In order to solve the above difficulties, need to develop a tooth form bolt sleeve with other stressed members.

Summary of the invention

The purpose of the utility model is to provide tooth form bolt sleeves.

Problem to be solved in the utility model is that the bolt sleeve of the prior art only has the problem of buried end is as stressed member.

To realize the purpose of this utility model, the technical solution adopted in the utility model is:

Tooth form bolt sleeve, including stress hook plate, half ring plate, bolt sleeve, first inner chamber, second inner chamber and threaded hole, it is described The upper end of bolt sleeve is bolted end, and the lower end of bolt sleeve is buried end, and the outer upper and lower ends of bolt sleeve are equipped with tooth form screw thread, The intermediate position of thread bush is smooth bar part, and half ring plate is each side arranged in smooth bar part, and stress hook is arranged in half ring plate side Plate, bolt sleeve bolted end is interior to be equipped with the threaded hole for accommodating bolt, is equipped with first inner chamber, bolt sleeve in the buried end of bolt sleeve Smooth bar part in be equipped with second inner chamber, first inner chamber and second inner chamber are interconnected.

The buried end bottom is equipped with multiple stress cylinders, and the diameter of the lower end of stress cylinder is greater than the upper end of stress cylinder Diameter.

The vertical portion of the stress hook plate and the angle at inclination position are 30 °.

The vertical portion of the stress hook plate and the angle at inclination position are 45 °.

The utility model has the advantages that: it is strong to improve stress of the bolt sleeve integrally in use as stressed member for stress hook plate Degree；Stress cylinder can also improve the stress intensity in use of bolt sleeve entirety, and the lower end of stress cylinder as stressed member As lateral stressed part, so that whole stress intensity is higher.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and embodiments.

In the utility model tooth form bolt sleeve 3, including stress hook plate 1, half ring plate 2, bolt sleeve 3, first inner chamber 4, second Chamber 5 and threaded hole 6, the upper end of the bolt sleeve 3 are bolted end 8, and the lower end of bolt sleeve 3 is buried end 7, outside bolt sleeve 3 Upper and lower ends are equipped with tooth form screw thread, and the intermediate position of thread bush is smooth bar part 9, and smooth bar part 9 each side installs half Ring plate 2, half ring plate 2 are welded on smooth bar part 9, and half ring plate, 2 side is welded stress hook plate 1, set in 3 bolted end 8 of bolt sleeve There is the threaded hole 6 for accommodating bolt, first inner chamber 4 is equipped in the buried end 7 of bolt sleeve 3, is equipped in the smooth bar part 9 of bolt sleeve 3 Second inner chamber 5, first inner chamber 4 and second inner chamber 5 are interconnected.

7 bottom of the buried end welding is equipped with multiple stress cylinders 10, and the diameter of the lower end of stress cylinder 10 is greater than stress The upper end diameter of cylinder 10.

The vertical portion of the stress hook plate 1 and the angle at inclination position are 30 °.

The vertical portion of the stress hook plate 1 and the angle at inclination position are 45 °.

The utility model application method: buried end 7, stress hook plate 1 and stress cylinder 10 are all as in Transducers Embedded in Concrete Buried component, stress hook plate 1 are used as stressed member, can improve the stress intensity in the whole use of bolt sleeve 3；10 conduct of stress cylinder Stressed member can also improve the whole stress intensity in use of bolt sleeve 3, and the lower end of stress cylinder 10 is as lateral stressed Part, so that whole stress intensity is higher.
