Abstract
The utility model relates to a tunnel construction tool, in particular to a lifting bolt sleeve for a tunnel lining. The lifting bolt sleeve mainly solves the technical problems that all the external thread of the prior bolt sleeve needs an circular arc shape, which results in more complicated processing technology, poor force tolerance and the like. The lifting bolt sleeve comprises a check valve (1), and is characterized in that the cross section of the external thread of the check valve (1) is sawtooth-shaped; one side of a stress surface is in the shape of a rectangle I (2), and the back side of the stress surface is in the shape of a rectangle II (3).
Description
Technical field
The utility model relates to a kind of constructing tunnel instrument, especially relates to a kind of to the tunnel duct piece isostructural improvement of lifting bolt sleeve.
Background technology
General construction tunnel concrete prefabricated arc sheet material commonly used is the concrete tunnel section of jurisdiction, makes the bolt sleeve that needs a pre-buried band internal and external threads in the tunnel duct piece process at constructing tunnel, so that handling and installation.Chinese patent discloses a kind of tunnel duct piece compound thread plastics lifting bolt sleeve (notice of authorization number: CN 2661991Y), it comprises a plastics lifting bolt sleeve that is provided with external screw thread and internal thread, the externally threaded cross sectional shape of this plastics lifting bolt sleeve is circular arc and trapezoidal composite construction, one side of stress surface is circular arc, and one side of back of the body stress surface is trapezoidal; The external screw thread cross section is that the hypotenuse on trapezoidal one side and the angle of vertical line are 5～10 degree.Chinese patent also discloses a kind of combined type pre-embedded bolt sleeve pipe that is used for ballastless track (notice of authorization number: CN 2839347Y), it has a nylon bolt sleeve pipe, the outside of nylon bolt sleeve pipe is socketed with a metal sleeve, the outer wall of the inwall of metal sleeve and nylon bolt sleeve pipe is provided with the screw thread that cooperatively interacts, and metal sleeve is connected on the nylon bolt sleeve pipe by thread bush; The bottom of metal sleeve is provided with a capping.But the external screw thread of these two kinds of bolt sleeves all needs circular arc, and processing technology is comparatively complicated, stressed relatively poor like this.
The utility model content
The utility model technical issues that need to address provide a kind of tunnel duct piece with lifting bolt sleeve, and it mainly is that the external screw thread that solves the existing in prior technology bolt sleeve all needs circular arc, and processing technology is comparatively complicated like this, the technical problem of stressed relatively poor grade.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Tunnel duct piece of the present utility model comprises flap valve with the lifting bolt sleeve, and the external screw thread section configuration that it is characterized in that described flap valve is a zigzag, one side that its stress surface is rectangle I, one side that back of the body stress surface is rectangle II.Flap valve can be made of plastics.The external screw thread of flap valve one side its stress surface and back of the body stress surface all is rectangle, can not only can be processed with engine lathe like this, and stressed relatively good.The length of rectangle I is greater than the length of rectangle II
As preferably, be socketed with holder on the described flap valve, the holder section is trapezoidal, the holder lower end is provided with socket, salient point and flap valve clamping that socket is provided with by flap valve or socket.
As preferably, described flap valve is connected with the grouting head by the internal thread of inside, and grouting crown end be a taper shape.The external screw thread of the external surface of a grouting body portion and the internal thread of flap valve inside are complementary, and guniting machine can inject cement in the grouting head.
As preferably, described flap valve lower end is connected with blind nut by internal thread, is provided with sealing ring between blind nut and the flap valve inside.The bottom of blind nut is the plane of sealing, and the internal thread of the external screw thread of blind nut external surface and flap valve inside is complementary.Blind nut can seal up whole bolt sleeve after grouting finishes.
Characteristics such as therefore, the external screw thread that the utlity model has bolt sleeve is made up of zigzag, and processing technology is comparatively simple like this, and external screw thread is stressed better, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is I portion structure for amplifying schematic diagrames of Fig. 1;
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: this routine tunnel duct piece is with lifting bolt sleeve, as Fig. 1, Fig. 3, a cylindrical flap valve 1 of integral body is arranged, the top of flap valve is socketed with a section and is trapezoidal holder 4, the holder lower end is connected with socket 5, and the external surface at flap valve 1 top is provided with salient point 9, and flap valve 1 is by salient point 9 and socket 5 clampings.The inside of flap valve 1 is connected with grouting 6 by internal thread, and grouting 6 top be taper shape.The below of grouting 6, promptly the lower end of flap valve 1 is connected with blind nut 7 by internal thread, the sealing of blind nut 7 bottoms, and be provided with sealing ring 8 between blind nut 7 and flap valve 1 inside.As Fig. 2, the external screw thread section configuration of flap valve 1 is a zigzag, one side that its stress surface is rectangle I2, one side that back of the body stress surface is rectangle II3.
During use, holder 4 is enclosed within on the flap valve 1 fixing, and is installed in the body of wall in tunnel, inject cement by guniting machine in grouting 6 then, cement can be washed open in holder 4 injection wall bodies, be in the milk finish after, blind nut 7 is sealed up flap valve 1 bottom, prevent from that cement from pouring in down a chimney out to get final product.
Claims (4)
1. a tunnel duct piece comprises flap valve (1) with the lifting bolt sleeve, and the external screw thread section configuration that it is characterized in that described flap valve (1) is a zigzag, one side its stress surface is rectangle I (2), one side back of the body stress surface is rectangle II (3).
2. tunnel duct piece according to claim 1 is with lifting bolt sleeve, it is characterized in that described flap valve (1) upper end is socketed with holder (4), the holder section is trapezoidal, the holder lower end is provided with socket (5), salient point and flap valve clamping that socket (5) is provided with by flap valve or socket.
