Abstract
An embedded sliding chute anchor leg extension connection member used in a tunnel aims at effectively solving the problem that an extension structure and a sliding chute anchor leg produce mutual adverse influence when a sliding chute anchor leg connection extension structure is embedded, and is convenient to assemble and disassemble so as to meet the needs of construction assembly and positioning. The embedded sliding chute anchor leg extension connection member comprises a U-shaped connecting member, a reserved sliding chute anchor leg and a limiting bolt assembly. A guide groove leading to the open end is formed in a base plate of the U-shaped connecting member, a limiting hole and an extension interface are formed in a top plate, and the limiting hole is close to the open end and corresponds to the guide groove. The longitudinal section of the reserved sliding chute anchor leg is T-shaped, the head portion of the reserved sliding chute anchor leg is clamped between the base plate and the top plate, and the anchor leg portion penetrates through the guide groove to extend downwards. A bolt in the limiting bolt assembly penetrates through the limiting hole and the guide groove.
Description
Technical field
The present invention relates to tunnel, particularly to a kind of tunnel built-in sliding chute anchor lower limb extension connecting elements.
Background technology
Now with country's railway network planning and construction, railway tunnel, vcehicular tunnel and subway occur in a large number between the mountain ridge and administrative region of a city, tunnel and in subway, are completed to meet later stage civil engineering
Rear-mounted cable or equipment etc. need, and now have started to introduce pre-buried channel flow technology. When setting pre-buried channel flow in plain concrete lining cutting, for meeting the stress needs of later stage suspension member, liner structure need to adopt the measures such as arrangement of reinforcement to strengthen. Present stage commonly used way has two kinds, a kind of way is vertically to be connected on chute anchor lower limb by the weldering of stiffener net, welding is adopted just to destroy the chute original zinc coat of anchor lower limb, namely the anticorrosive coat of chute anchor lower limb is destroyed, make the easy corrosion of anchor lower limb, shorten the service life of anchor lower limb, if anchor lower limb comes off during operation, will result in the severe safety accident of car crash and huge economic loss; Another kind of method be by stiffener mesh sheet colligation on built-in sliding chute anchor lower limb, but the restriction due to colligation intensity, lining cutting stiffener mesh sheet is difficult to effectively location, when lining concrete is built, reinforced mesh is under the effect of concreting power, position very easily changes, and stiffener mesh sheet effectively can not play a role by design. The likely drawing crack lining cutting when chute place davit power is sufficiently large, in some instances it may even be possible to cause chute place lining concrete to fall block and come off, jeopardize traffic safety and cause serious accident. All there is certain potential safety hazard in the method for attachment of existing both the above lining cutting stiffener net and anchor lower limb, haves much room for improvement.
Summary of the invention
The technical problem to be solved is to provide a kind of tunnel built-in sliding chute anchor lower limb extension connecting elements, effectively to solve expansion structure and the problem of chute anchor lower limb mutual adverse effect when built-in sliding chute anchor lower limb connects expansion structure, and disassemble easy to assembly, assemble with satisfied construction and location needs.
The technical solution adopted for the present invention to solve the technical problems is as follows:
The tunnel built-in sliding chute anchor lower limb extension connecting elements of the present invention, is characterized in that: include U-shaped connecting elements, reserved chute anchor lower limb and caging bolt assembly; Arranging on the base plate of described U-shaped connecting elements and lead to the gathering sill of opening, top board arranges spacing hole and expansion interface, spacing hole is near opening and corresponding with gathering sill;The vertical section of described reserved chute anchor lower limb is T-shaped, and its head is stuck between base plate, top board, and anchor leg downwardly extends through gathering sill; Bolt in described caging bolt assembly passes spacing hole and gathering sill.
ThisInventionProviding the benefit that, this anchor lower limb extension component is disassembled easy to assembly, and the construction being well positioned to meet expansion structure assembles and location needs, eliminates operation security hidden danger. Adopt this extension connector can effectively solve built-in sliding chute anchor lower limb and the connectivity problem being connected extension, be difficult to the problems such as restriction reinforced mesh position with liner structure stiffener mesh sheet colligation as chute anchor lower limb welds the destruction zinc-plated problem of anchor lower limb, chute anchor lower limb with liner structure stiffener mesh sheet; Adopt this extension connector can provide strong interface for other expansion structures, facilitate other expansion structures to access, eliminate again the security hidden trouble that existing anchor lower limb is connected with lining cutting stiffener, safely provided effective guarantee for railway operation.

Component shown in figure and corresponding labelling: U-shaped connecting elements 10, base plate 10a, top board 10b, gathering sill 11, spacing hole 12, expansion interface 13, reserved chute anchor lower limb 20, head 21, anchor leg 22, bolt assembly 30.
Detailed description of the invention
The present invention is further described to execute example below in conjunction with accompanying drawing and real *.
With reference to Fig. 1, the tunnel built-in sliding chute anchor lower limb extension connecting elements of the present invention includes U-shaped connecting elements 10, reserved chute anchor lower limb 20 and caging bolt assembly 30. With reference to Fig. 2 and Fig. 4, the base plate 10a of described U-shaped connecting elements 10 on, the gathering sill 11 of opening is led in setting, and top board 10b arranges spacing hole 12 and expansion interface 13, and spacing hole 12 is near opening and corresponding with gathering sill 11. With reference to Fig. 1 and Fig. 3, the vertical section of described reserved chute anchor lower limb 20 is T-shaped, and its head 21 is stuck between base plate 10a, top board 10b, and anchor leg 22 downwardly extends through gathering sill 11. With reference to Fig. 1, the bolt in described caging bolt assembly 30 passes spacing hole 12 and gathering sill 11. When adopting this extension connector can effectively solve built-in sliding chute anchor lower limb connection expansion structure, the problem of expansion structure and the mutual adverse effect of chute anchor lower limb, and chute anchor lower limb welds the destruction zinc-plated problem of anchor lower limb with liner structure stiffener mesh sheet, and chute anchor lower limb is difficult to limit the problems such as reinforced mesh position with liner structure stiffener mesh sheet colligation. This anchor lower limb extension component is disassembled easy to assembly, is well positioned to meet construction and assembles and location needs.
The transverse section of described anchor leg 22 is square or circular.
Some principles of the above tunnel of the present invention built-in sliding chute anchor lower limb extension connecting elements that simply explains through diagrams, it is not intended to the present invention be confined in shown and described concrete structure and the scope of application, therefore every corresponding amendment being likely utilized and equivalent, belong to the scope of the claims that the present invention applies for.
