Description
Technical field:
The present invention relates to the realm of building construction, specifically refer to a kind of reinforced concrete sandwich hollow superstructure.
Background technology:
At present, the floor spiced by steel reinforced concrete of domestic employing can bear bidirectional load, does not need on-the-spot formwork, and cost is low, and lifting, transportation are easily.Publication number be CN101831976A patent disclosure a kind of prefabricated steel rib bottom plate-concrete overlapped hollow floor system, comprise band reinforcing bar rib precast concrete base plate, vertical reinforcing bar rib, hollow mould carriage, hollow mould top board, cast-in-place overlapping layers concrete, this building cover structure is to place square hollow mould on band reinforcing bar rib precast concrete base plate, reproduction is watered the overlapping layers concrete and is formed overlapped hollow floor system, and this superstructure has that bearing capacity is big, anti-seismic performance good, can increase advantage such as floor headroom.But hollow mould directly is placed on the base plate, during cast-in-place overlapping layers concrete, concrete only with the side and the end face bonding of hollow mould, with the bottom surface of hollow mould bonding not, make that the overall performance of this overlapped hollow floor system is bad.Simultaneously, the height of the hollow mould top board in this overlapped hollow floor system is not less than the height of reinforcing bar rib, and during cast-in-place overlapping layers concrete, hollow mould may be subjected to concrete buoyancy and to come-up, bring very big inconvenience to construction like this.
Summary of the invention:
The object of the present invention is to provide a kind of reinforced concrete sandwich hollow lid of being convenient to construct.Advantages such as this reinforced concrete sandwich hollow superstructure has that overall performance is good, feed consumption is few, it is light to estimate one's own ability, easy construction, stress performance are good.
The object of the present invention is achieved like this, this overlapped hollow floor system comprises precast plate with ribbing, precast hollow pipe, cast-in-situ concrete overlapping layers, precast plate with ribbing comprises base plate and vertical rib, on the vertical rib hole is arranged, transverse reinforcement passes hole and connects polylith precast plate with ribbing, the precast hollow pipe that the invention is characterized in described overlapped hollow floor system is parallel to vertical rib direction and is arranged between the adjacent vertical rib, and be arranged in transverse reinforcement above.During construction, polylith precast plate with ribbing is close to, now wears the hole that transverse reinforcement passes both sides under the vertical rib of prefabricated units, connect polylith precast plate with ribbing; Placement precast hollow pipe on transverse reinforcement, precast hollow pipe two ends are blocked with the end plug, with securing member the precast hollow pipe are linked to each other with precast plate with ribbing; At vertical rib top assembling reinforcement net, the concreting overlapping layers makes precast plate with ribbing, precast hollow pipe, reinforcing bar become whole overlapped hollow floor system again.
Feature of the present invention is that also steel mesh reinforcement is arranged at reinforced concrete sandwich hollow superstructure top.The steel mesh reinforcement that top is arranged in length and breadth can be strengthened the bonding between prefabricated units and the cast-in-situ concrete, strengthens the globality of overlapped hollow floor system.
Feature of the present invention is that also the precast hollow pipe in the reinforced concrete sandwich hollow superstructure links to each other with precast plate with ribbing by securing member.When concreting, because securing member is to the effect of contraction of precast hollow pipe, the fixed-site of precast hollow pipe can not be subjected to concrete buoyancy and to come-up, this brings convenience to construction.
Feature of the present invention is that also the vertical rib of precast plate with ribbing is single rib or many ribs.Many ribs can further improve the strength and stiffness of precast plate, and the making of being convenient to the large span precast plate is used.When making whole overlapped hollow floor system, many ribs can strengthen bonding and the build-in between precast plate and the cast-in-situ concrete, and stress performance, the overall performance of overlapped hollow floor system are higher.
Feature of the present invention is that also the vertical rib of precast plate with ribbing is T shape or rectangle.Vertical rib can increase the intensity of precast plate, improves the rigidity of precast plate, and the vertical rib of T shape has bigger rigidity, has improved effective conversion height of precast plate.When making whole overlapped hollow floor system, between precast plate and the cast-in-situ concrete bond strength of combination interface and collaborative work better, stress performance, the overall performance of overlapped hollow floor system are higher.
Feature of the present invention is that also precast hollow pipe form of fracture is for circular.During fluid concrete, concrete can flow to the downside of circular hollow tube, wraps hollow section, and concrete folding layer and hollow section can better bond like this.
Feature of the present invention is that also the precast hollow pipe has the end plug.Because the precast hollow pipe has the end plug, in work progress, concrete can not flow in the precast hollow pipe.
