Abstract
The invention discloses a kind of novel embedded part that is used to connect guide strip and concrete beam body, comprise embedded part body, one platform structure is set, be used to connect guide strip at an end of described embedded part body; On described platform structure, vertically offer a connecting hole, and run through embedded part body.The present invention solves the connectivity problem of guide strip and concrete beam body on the floating concrete track beam of monolithic magnetic.Guarantee simultaneously that embedded part is built at concrete beam body and bury in the process that to put the location convenient; Easy to operate in later stage machine and stator installation process, fastening reliable.
Description
Technical field
The invention belongs to monolithic magnetic suspension concrete track beam applied technical field, also can amplify and be applied to other concrete construction field, specifically, the present invention relates to a kind of novel embedded part that is used to connect guide strip and concrete beam body.
Background technology
The whole functional district is a full steel structure in the existing magnetic levitation track girder technology, and steel work is connected with concrete beam body again, and steel using amount is big.Concrete structure is intended adopting in existing functional areas, and guide strip installs and fixes the form that connects built-in fitting that adopts, but lacks ready-made practical experience for the form of built-in fitting.
Summary of the invention
The objective of the invention is to develop a kind of novel embedded part, and then solve the connectivity problem of guide strip and concrete beam body on the floating concrete track beam of monolithic magnetic.Guarantee simultaneously that embedded part is built at concrete beam body and bury in the process that to put the location convenient; Easy to operate in later stage machine and stator installation process, fastening reliable.
In order to achieve the above object, the invention provides a kind of novel embedded part that is used to connect guide strip and concrete beam body, comprise embedded part body, one platform structure is set, be used to connect guide strip at an end of described embedded part body; On described platform structure, vertically offer a connecting hole, and run through embedded part body.
The other end in described embedded part body vertically is provided with some installing holes, and described installing hole connects dowel.
The arranged outside of described embedded part body has ribs.
The end face of described platform structure is provided with some locating holes.
The present invention has the following advantages:
1. the location of embedded part, pre-buried problem have well been solved;
2. machine and easy for installation, fastening reliable;
3. the embedded part steel using amount is little, economic and reliable.
Description of drawings
Fig. 1 is the structure chart of novel embedded part provided by the invention;
Fig. 2 is the structure chart of the another side of novel embedded part provided by the invention;
The specific embodiment
Followingly specify a kind of better embodiment of the present invention according to Fig. 1～2:
As shown in Figure 1 and Figure 2, the novel embedded part that the present invention is used to connect guide strip and concrete beam body comprises embedded part body 2, end in described embedded part body 2 is provided with platform structure 7, and conduct contacted the carrier that is connected with guide strip after the effect of platform structure 7 was fine finishining.Embedded part body 2 all is embedded in concrete beam body inside.On described embedded part body 2 other ends two installing holes 21 are set vertically, are used to install dowel 1, to strengthen the anchored force of embedded part, also be provided with ribs on embedded part body 2, the effect of ribs also is to improve anchored force.
The end face 5 of platform structure 7 is that contact surface is installed, on the position that is cornerwise two angles on this installation contact surface 5, two locating holes 4 are set, described locating hole 4 is as the location benchmark of this embedded part, and its effect is to water in the process of smashing as the beam body concrete to be fixedly coupled the hole with template.The position of locating hole 4 needs on platform structure accurately location, and the degree of depth of locating hole 4 is reserved the size of chipping allowance according to design, and comprehensively determines according to precision controlling level in the actual production, thereby does not impact contact surface 5 is installed.
The present invention is used to connect the novel embedded part employing monoblock cast mode of guide strip and concrete beam body, the making processing of embedded part needs to carry out and strengthen quality inspection in strict accordance with designing requirement, specification need be controlled in the designing requirement accuracy rating, to guarantee supporting capacity; And want strict control cast casting quality, and avoid occurring defectives such as pore, require when satisfying fine finishining and the supporting capacity of embedded part.
This embedded part to bury process underground as follows: the inspection of quality before at first embedded part being installed, dowel 1 is installed in qualified back, dowel 1 is connected with embedded part body 2 by installing hole 21, is screwed into the degree of depth and needs strict control, avoids being screwed into the shallow bonding strength deficiency that causes, then, carry out embedded part and be connected, connect locating hole 4 with bolt embedded part is fixed on the rail beam making template, and rail beam is made template adjustment location with the installation that rail beam is made template, after qualified by inspection, disturbing concrete again.After finishing, the rail beam casting and compacting of concrete enters curing time.At first, carry out stream curing, after reaching form removal and pretensioned prestressing and putting a condition, form removal, put open, lifting; Afterwards, enter the natural curing phase, maintenance to 60 day length of time, during through twice post-stressed stretch-draw with wait for applying of load.The curing time end of beam body, carry out machine tooling, to being installed, contact surface 5 carries out grinding, by measurement, with reference to circuit geodetic coordinates parameter to the beam body, be ground to the assembling controlling dimension of beam body and bore connecting hole 3,,, locate by the envelope method balance according to the circuit geodetic coordinates by the measurement to the beam body by Digit Control Machine Tool the position of connecting hole 3, determine the optimum position of connecting hole 3, and reach the diameter and the degree of depth of the connecting hole 3 of designing requirement.Guide strip and fastening is installed afterwards, and guide strip adopts high-strength bolt to be connected with connecting hole.
The invention solves the connectivity problem of guide strip and concrete beam body on the floating concrete track beam of monolithic magnetic.Guarantee simultaneously that embedded part is built at concrete beam body and bury in the process that to put the location convenient, easy to operate in later stage machine and stator installation process, fastening reliable.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited to the appended claims.
