Description
Technical Field
The utility model belongs to side slope engineering field especially relates to a hollow prefabricated assembled lattice beam structure of component.
Background
The traditional lattice beam is cast in situ, so that the anchor cable can be tensioned after the concrete curing age, the construction time is long, and the excavated side slope cannot be supported in time. In addition, as the site formwork is poured, the lattice beams are all solid, but the safety redundancy of the solid lattice beams is larger in terms of stress requirements. Therefore, the study of the lattice beam technology which can realize quick supporting and save materials has important engineering significance.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a hollow prefabricated assembled lattice beam structure of component to solve the quick supporting problem after the slope excavation in the side slope engineering.
In order to realize the technical purpose, the utility model discloses a following technical scheme:
a hollow prefabricated assembly type lattice beam structure of a component is formed by splicing a prefabricated cross beam and a prefabricated cross beam, each end part of the prefabricated cross beam is connected with the prefabricated cross beam, and a reserved anchoring hole for anchoring an anchor rope or an anchor rod is reserved in the center of the prefabricated cross beam;
the beam bodies of the prefabricated cross beam and the prefabricated cross beam are both of hollow structures, steel members are embedded in the end parts of the prefabricated cross beam and the prefabricated cross beam, and the prefabricated cross beam are connected through the steel members; and reinforcing connecting and tying ribs which are obliquely arranged are arranged at the transverse and longitudinal joint of the prefabricated cross beam.
Furthermore, the bottom of the reserved anchoring hole of the prefabricated cross beam is provided with a pre-embedded steel gasket for anchoring an anchor cable or an anchor rod.
Further, the prefabricated cross beam is of a reinforced concrete structure.
The utility model has the advantages as follows:
1. the utility model discloses a component is prefabricated, the scene is assembled, can save engineering time and maintenance time.
2. The utility model discloses a prefabricated, the on-the-spot assembly of component can carry out stretch-draw supporting to the side slope sooner, improves the stability of side slope in the work progress.
3. The utility model discloses a make cavity with prefabricated component, saved the quantity of concrete, economic environmental protection more.
