Abstract
The utility model discloses a reinforced concrete precast unit for superposition beam, which is a reinforced concrete groove shape precast unit. Because the reinforced concrete groove shape precast unit is of thin bottom plate and light weight, the side wall of the groove shape precast unit is of longitudinal ribs. The utility model has advantages of high anti bending moment, bearing capacity, and anti breaking. The reinforced concrete precast unit for superposition beam is convenient to transport and hoisting, and also has the function of side mould. Therefore when the beam is to be folded, a longitudinal reinforcing rid is connected with the inner upper end and the inner lower end of a stirrup. Then the reinforced concrete groove shape precast unit is cast with concrete to be folded to form the beam. The construction is simple and time is saved.
Description
Technical field:
The utility model relates to the realm of building construction, specifically refers to a kind of precast member for reinforcing bar concrete that is used for superposed beam.
Background technology:
Existing reinforced concrete sandwich beam is used the rectangle precast member for reinforcing bar concrete usually, during construction, and a first good side template on the rectangle precast member for reinforcing bar concrete, configuration reinforcement then, concreting forms superposed beam again.But thin rectangle prefabricated units bending resistance square supporting capacity is poor, and frangibility, thick rectangle prefabricated units are from great, and lifting, transportation are inconvenient; And side form need to be installed, and construction is complicated, expend time in.
Summary of the invention:
It is a kind of from heavy and light that the purpose of this utility model is to provide, bending resistance square supporting capacity by force, frangibility not, lifting, convenient transportation, do not need to install side form again, construction is simple, save time, and is used for the precast member for reinforcing bar concrete of superposed beam.
The purpose of this utility model is achieved like this, and this precast member for reinforcing bar concrete that is used for superposed beam is steel concrete flute profile prefabricated units.
Because steel concrete flute profile prefabricated units base plate is thin, from heavy and light, its flute profile prefabricated units sidewall is a longitudinal rib, bending resistance square supporting capacity is strong, frangibility not, lifting, convenient transportation also play the effect of side form, during superposed beam, interior upper and lower end at stirrup connects longitudinal reinforcement, and concreting can be overlapped into beam in the groove of steel concrete flute profile prefabricated units again, constructs simply, saves time.
Description of drawings:
Fig. 1 is the precast member for reinforcing bar concrete structural representation that is used for superposed beam
Fig. 2 is used for concreting structural representation in the precast member for reinforcing bar concrete groove of superposed beam for Fig. 1
The specific embodiment:
With reference to figure 1, Fig. 2, this precast member for reinforcing bar concrete that is used for superposed beam is steel concrete flute profile prefabricated units 4, stirrup 9 is set in prefabricated units groove 2, its flute profile prefabricated units 4 sidewalls are longitudinal rib, also play the effect of side form, on precast member for reinforcing bar concrete 4 sidewalls, have installing hole 3.
During superposed beam, use fixedly batten 8 support shutterings of bolt 6 on installing hole 3, the interior upper and lower end of stirrup 9 connects longitudinal reinforcement 5, and concreting can be overlapped into beam 7 in the groove 2 of steel concrete flute profile prefabricated units again.
Buying in advance and bury reinforcing bar 1 can be prestressed reinforcement or nonprestressed reinforcement, is used to improve the bearing capacity and the cracking resistance of flute profile prefabricated units 4.
