Abstract
The utility model discloses a section of jurisdiction steel mould mounting structure. It includes the steel reinforcement cage that section of jurisdiction steel mould and section of jurisdiction steel mould surface set up, is provided with a plurality of mounting holes that are used for installing pre-buried sleeve on the section of jurisdiction steel mould, is provided with the location end that sleeve main part and sleeve main part top set up on the pre-buried sleeve, and the lower surface of location end is provided with two and is 180 degrees ribs of arranging in the sleeve main part, and pre-buried sleeve carries out the interference fit installation with each mounting hole and makes the rib spacing on section of jurisdiction steel mould surface. After adopting foretell structure, its structural design is very simple, and the construction is also very convenient and fast, no longer need the welding steel band, has practiced thrift construction material and has improved the efficiency of construction greatly, especially through the interference fit's of the pre-buried sleeve that has the rib and section of jurisdiction steel mould mounting structure, has still improved the accuracy and the reliability of installation greatly, has effectively solved because of placing the steel reinforcement cage and has leaded to pre-buried sleeve's displacement and come-up problem with pouring the concrete in addition.
Description
Technical Field
The utility model relates to a mounting structure of section of jurisdiction in the tunnel, specifically speaking are section of jurisdiction steel mould mounting structure.
Background
Among the prior art, tunnel among the track traffic is the pipeline formula structure, the tunnel inner wall is formed by the concatenation of multi-disc section of jurisdiction, and the section of jurisdiction all adopts the steel reinforcement cage to go up the welding steel band usually in the installation, then cast molding's concrete structure, carry out fixed mounting with nylon swivel nut and pre-buried sleeve after the welding, this kind of mounting structure of current, use a large amount of steel bands to make the material extravagant serious and inefficiency, the construction process is also very complicated and hardly guarantee the accuracy of location in the installation, in addition, place the steel reinforcement cage and the problem that the in-process of pouring concrete still makes pre-buried sleeve produce displacement and come-up easily.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a section of jurisdiction steel mould mounting structure that structural design is simple, construction convenience, efficiency of construction are high and the location is accurate.
In order to solve the technical problem, the utility model discloses a section of jurisdiction steel mould mounting structure, including the steel reinforcement cage that section of jurisdiction steel mould and section of jurisdiction steel mould surface set up, be provided with a plurality of mounting holes that are used for installing pre-buried sleeve on the section of jurisdiction steel mould, pre-buried sleeve includes the location end that sleeve main part and sleeve main part top set up, and the lower surface of location end is provided with two and is 180 degrees ribs of arranging in the sleeve main part, pre-buried sleeve and each the mounting hole carries out the interference fit installation and makes the rib impress in the upper surface of section of jurisdiction steel mould.
And a threaded hole is formed in the center of the embedded sleeve.
The lower surface of the positioning end of the embedded sleeve is of a conical surface structure, and the ribs are arranged on the conical surface.
And pouring concrete after the embedded sleeve is installed in interference fit with the duct piece steel die.
The depth of the threaded hole is smaller than more than half of the length of the embedded sleeve.
The lower surface of location end is provided with two and is 180 degrees arrangement ribs in the sleeve main part.
After adopting foretell structure, the structure that has utilized special pre-buried sleeve directly carries out interference fit installation with section of jurisdiction steel mould, its structural design is very simple, the construction is also very convenient and fast, no longer need the welded steel band, practice thrift construction material and improved the efficiency of construction greatly, especially the interference fit's mounting structure through the pre-buried sleeve that has the rib and section of jurisdiction steel mould, still improved the accuracy and the reliability of installation greatly, but also effectively solved because of placing the steel reinforcement cage and pouring the concrete and lead to pre-buried sleeve's displacement and come-up problem.
Drawings
Fig. 1 is a schematic structural view of the mounting structure of the duct piece steel die of the present invention;
fig. 2 is the utility model discloses section structure schematic diagram of section of jurisdiction steel mould mounting structure's part.
Detailed Description
The structure for mounting a segment steel die according to the present invention will be described in detail with reference to the accompanying drawings and embodiments.
As shown in the figures, the utility model discloses a segment steel die mounting structure, including segment steel die 1 and the steel reinforcement cage 8 that the segment steel die surface set up, be provided with a plurality of mounting holes that are used for installing pre-buried sleeve 2 on the segment steel die 1, pre-buried sleeve 2 includes sleeve main part 3 and the location end 4 that the sleeve main part top set up, the center of pre-buried sleeve 2 is provided with screw hole 6, wherein, the depth of screw hole 6 is less than half more than pre-buried sleeve 2 length, in order to improve joint strength under the prerequisite that satisfies the installation demand, pre-buried sleeve 2 carries out interference fit with each mounting hole and installs in the upper surface of segment steel die, pour into concrete 7 after pre-buried sleeve 2 and segment steel die 1 interference fit installation, in this embodiment, the diameter of each mounting hole is phi 19.5mm, and the external diameter of sleeve main part is phi 20mm, pre-buried phi sleeve 20mm knocks into the mounting hole of phi 19.5mm on the segment steel, fix through the extrusion between the metal, this kind of mode is fixed more firm, and the location is accurate and utilize the rib to realize reliable installation, can solve because place the steel reinforcement cage and pour into water concrete and lead to embedded sleeve's displacement and come-up problem.
Furthermore, a threaded hole is formed in the center of the embedded sleeve, the lower surface of the positioning end of the embedded sleeve is of a conical surface structure, and the ribs are arranged on the conical surface.
Still further, can also be provided with two at the lower surface of location end 4 and be 180 degrees and arrange rib 5 in the sleeve main part, pre-buried sleeve 2 carries out interference fit installation and plays the effect of preventing the pivoted after concrete placement with each mounting hole for pre-buried sleeve's stability is better, can not produce the displacement, and operational reliability is also better, and the effect is better outstanding.
