Abstract
The utility model relates to a door opening type bearing framed bent device for design surfaces of a multiplayer concrete box girder. The door opening type bearing framed bent device comprises the design surface of an upper concrete box girder and the design surface of a lower concrete box girder and is characterized in that a cast-in-place beam framed bent is arranged under the design surface of the upper concrete box girder, and a door opening type framed bent is erected above the design surface of the lower concrete box girder, wherein the door opening type framed bent is composed of a row of steel pipes with two vertical ends and joist steel arranged at the top, reinforced concrete strip foundations are laid at the footing of the steel pipes, the joist steel is laid on a steel row formed by the transverse single joist steel along the longitudinal direction, and the distances between the joist steel are the distances of vertical rods of the cast-in-place beam framed bent arranged under the design surface of the upper concrete box girder. The door opening type bearing framed bent device provided by the utility model has the advantage that the upper cast-in-place box girder and the lower cast-in-place box girder can be simultaneously constructed, thereby one half of construction time is saved, and the construction progress of a cast-in-place box girder at an interchange section is greatly accelerated.
Description
Technical field
The utility model relates to a kind of door opening formula bearing bent frame device that is used for multi-layer concrete case beam.
Background technology
Along with the develop rapidly of urban construction, elevated road is as increasing being applied in the urban construction of a kind of mode of alleviating urban highway traffic pressure at present.Along with the development of elevated road, complicated multilayer, also increasing being applied in the urban construction of elevated bridge of multiple structure.In general, multilayer viaduct box girder construction is to construct according to principle from top to bottom, builds cast-in-place beam framed bent at the superiors place exactly; Utilize intensive vertical rod and ground supports below the cast-in-place beam framed bent, on the top of vertical rod, lay the template of concrete casting again, wire-tie and carry out concrete casting; Because the floor height of the overpass bridge the superiors that have is very high, therefore whole workload of building cast-in-place beam framed bent is very big, and the duration is also very long; And sometimes the duration very urgent, so after treating that the upper strata box girder construction finishes, reach the standard value of design after; Carry out the construction of lower floor's case beam again; Can cause the whole construction cycle to prolong greatly, therefore demand urgently existing construction is improved, carry out simultaneously so that the construction of multilayer viaduct case beam can realize levels.
Summary of the invention
The purpose of the utility model is can't carry out the existing problem of lower floor's box girder construction when solving the upper strata box girder construction of multilayer viaduct case beam in the prior art, and a kind of door opening formula bearing bent frame device that is used for multi-layer concrete case beam design surface is provided.The utility model is designed for the door opening formula bearing bent frame device of multi-layer concrete case beam design surface; Be included in upper strata concrete box girder design surface, lower-layer concrete case beam design surface; It is characterized in that: below the concrete box girder design surface of upper strata, be provided with cast-in-place beam framed bent; Above lower-layer concrete case beam design surface, set up door opening formula framed bent; Door opening formula framed bent is upright steel pipe by row two ends, and steel pipe top is provided with single i iron and constitutes, and is equipped with steel bar concrete strip basis at the footing of steel pipe; On the steel row that horizontal single i iron constitutes, longitudinally be equipped with i iron, the spacing of i iron is the vertical pole ' s span of the cast-in-place beam framed bent that is provided with of the below of upper strata concrete box girder design surface.It is characterized in that: arrange double steel bar in the steel bar concrete strip basis, press spacing pre-embedded steel slab below steel pipe of steel pipe.It is characterized in that: the vertical rod in the cast-in-place beam framed bent that the below of upper strata concrete box girder design surface is provided with is connected with joist with horizon bar adopts right-angle coupler; Other vertical rods of top rod member and below of vertical rod are connected adopts rotary buckle, other vertical rod to link to each other employing with vertical rod to clasp; Horizon bar connects employing to clasp; The spreading of bridging and adopt rotary buckle with being connected of vertical rod.The utility model has the advantages that two-layer cast-in-situ box girder can be constructed simultaneously up and down, saved the half the engineering time, thereby accelerated the construction speed of grade separation section cast-in-situ box girder greatly.
Description of drawings
Figure is the structural representation of the utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment
Be included in upper strata concrete box girder design surface, lower-layer concrete case beam design surface among the figure; It is characterized in that: below the concrete box girder design surface of upper strata, be provided with cast-in-place beam framed bent; Above lower-layer concrete case beam design surface, set up door opening formula framed bent; Door opening formula framed bent is upright steel pipe by row two ends, and steel pipe top is provided with single i iron and constitutes, and is equipped with steel bar concrete strip basis at the footing of steel pipe; On the steel row that horizontal single i iron constitutes, longitudinally be equipped with i iron, the spacing of i iron is the vertical pole ' s span of the cast-in-place beam framed bent that is provided with of the below of upper strata concrete box girder design surface.It is characterized in that: arrange double steel bar in the steel bar concrete strip basis, press spacing pre-embedded steel slab below steel pipe of steel pipe.It is characterized in that: the vertical rod in the cast-in-place beam framed bent that the below of upper strata concrete box girder design surface is provided with is connected with joist with horizon bar adopts right-angle coupler; Other vertical rods of top rod member and below of vertical rod are connected adopts rotary buckle, other vertical rod to link to each other employing with vertical rod to clasp; Horizon bar connects employing to clasp; The spreading of bridging and adopt rotary buckle with being connected of vertical rod.
When building overpass bridge; When upper and lower layer concrete case beam needs construction synchronously, cast-in-place beam framed bent can below the concrete box girder design surface of upper strata, be built, so that the concrete spouting of upper strata concrete box girder; And below the place that intersects with lower-layer concrete case beam design surface; Can below the concrete box girder design surface above build door opening formula framed bent, support with the cast-in-place beam framed bent that upper strata concrete box girder design surface below is built, after the door opening formula framed bent on the concrete box girder design surface of below is built; Can carry out the construction of the cast-in-place beam framed bent of upper and lower layer concrete case beam simultaneously, shorten the duration of construction greatly.
