The utility model discloses a kind of pre-buried channel flow T-bolts in mounting technique field in subway tunnel, including screw rod, the top of the screw rod is integrally formed and is connected with screw head, the front-rear side walls of the screw head are welded with tooth plate, the front side wall of the front side tooth plate and the rear wall of rear side tooth plate are uniformly provided with teeth, half slot is provided at left and right sides of the front side tooth plate and rear side tooth plate bottom, this kind of pre-buried channel flow T-bolt device, design is reasonable, it is practical, using the combination of tooth plate and teeth, increase conventional bolt frictional strength and contact area, the preformed hole and conduit contact area and frictional force for making bolt and shield piece increase, solve the problems, such as that bolt falls off from shield on piece.
Description
Technical field
The utility model belongs to mounting technique field in subway tunnel, is a kind of pre-buried channel flow T-bolt.
Background technique
Subway tunnel can be divided into the end patterns such as rectangle, arch, circle and ellipse by running tunnel section configuration,
Rectangular end face can be divided into single span, twin spans and multispan type, and circular cross section can be divided into Dan Yuan and more circle two types, and subway tunnel needs
Electromechanical equipment to be installed by bolt, tommyhead bolt is inserted into preset hole on subway tunnel shield plate, is poured later
It is fixed, however connecting T-shaped bolt used when mechanical and electric equipment installation in existing subway tunnel is smooth, contact surface is small, is mounted on shield
Bolt in piece is easy to fall off, and the equipment of installation is caused to fall damage or cause to damage to pedestrian passing in tunnel or vehicle
It loses, it is therefore desirable to which current bolt is improved further.
Utility model content
The purpose of this utility model is to provide a kind of pre-buried channel flow T-bolts, to solve to mention in above-mentioned background technique
Out however connecting T-shaped bolt used when mechanical and electric equipment installation in existing subway tunnel is smooth, contact surface is small, is mounted on shield piece
Interior bolt is easy to fall off, and the equipment of installation is caused to fall damage or cause damages to pedestrian passing in tunnel or vehicle
The problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of pre-buried channel flow T-bolt, including
Screw rod, the top of the screw rod, which is integrally formed, is connected with screw head, and the front-rear side walls of the screw head are welded with tooth plate, described in front side
The front side wall of tooth plate and the rear wall of rear side tooth plate are uniformly provided with teeth, the front side tooth plate and rear side tooth plate bottom or so
Two sides are provided with half slot.
Preferably, the height of the screw head is 25 millimeters.
`
Preferably, the diameter of the screw rod is 24 millimeters.
Preferably, the diameter of the screw head is 40 millimeters.
Preferably, the length of the tooth plate is 60 millimeters.
Preferably, the diameter of the half slot is four millimeters.
Compared with prior art, the utility model has the beneficial effects that this kind of pre-buried channel flow T-bolt device, design
Rationally, practical, using the combination of tooth plate and teeth, increases conventional bolt frictional strength and contact area, make bolt
Increase with the preformed hole and conduit contact area and frictional force of shield piece, solves the problems, such as that bolt falls off from shield on piece.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model structure top view；
Fig. 3 is the utility model mounting structure schematic diagram.
In figure: 1 screw rod, 2 screw heads, 3 tooth plates, 4 teeth, 5 half slots, 6 shield pieces, 7 preformed holes, 8 conduits.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of pre-buried channel flow T-bolt, including screw rod
1, the top of the screw rod 1, which is integrally formed, is connected with screw head 2, and the front-rear side walls of the screw head 2 are welded with tooth plate 3, front side institute
The rear wall of the front side wall and rear side tooth plate 3 of stating tooth plate 3 is uniformly provided with teeth 4, and teeth 4 and tooth plate 3 cooperate, and increases bolt and shield
The coefficient of friction and contact area of tile 6 make bolt be not easy to fall from shield piece 6, the front side tooth plate 3 and rear side tooth plate
Half slot 5 is provided at left and right sides of 3 bottom.
Wherein, the height of the screw head 2 is 25 millimeters, and the diameter of the screw rod 1 is 24 millimeters, the screw head
2 diameter is 40 millimeters, and the length of the tooth plate 3 is 60 millimeters, and the diameter of the half slot 5 is four millimeters.
Specifically, in use, as shown in figure 3, the screw head 2 in the present apparatus, tooth plate 3 are inserted into preset on shield piece 6
In preformed hole 7 and the conduit 8 opened up, concrete is poured into preformed hole 7 and conduit 8 by casting equipment later, concrete seeps
Enter into teeth 4, after the dry solidifying reality of concrete, concrete is combined closely with teeth 4, and frictional force increases, and concrete
Increase with the contact area of tooth plate 3, makes bolt fastening in shield piece 6, bolt is avoided to fall off out of shield piece 6.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
