Abstract
The invention relates to a connection method for reinforcing joints between pre-fabricated hollow slabs and a horizontal beam by embedding steel reinforcements. The connection method comprises the steps of: symmetrically forming grooves with length of L on the front and rear sides of two opposite pre-fabricated hollow slabs on two sides of the horizontal beam, respectively arranging steel reinforcements horizontally connecting the two pre-fabricated hollow slabs in the symmetrically formed grooves, then arranging steel reinforcements which are aslant crossed in an X shape at the middle between the two pre-fabricated hollow slabs, then pouring fine gravel concrete on the horizontal beam at the middle between the two pre-fabricated hollow slabs, and finally applying a layer of fine gravel concrete with thickness of 20 mm at the joints between the pre-fabricated hollow slabs and the horizontal beam. According to the invention, by reinforcing the connecting joints, the integrality of the joints between the pre-fabricated hollow slabs and the horizontal beam is increased, the synergic deformability of each side force resisting component is increased and the interlayer displacement of the structure is reduced, thus the local or integral collapsing of a masonry structure is avoided as much as possible; and the structure is simple, convenient and effective, and can enhance the tensile and shear resisting bearing capacity of the joints so as to achieve the reinforcing purpose.
Description
Technical field
The present invention relates to imbed the method for attachment of steel reinforcing precast hollow slab and standard width of a room in an old-style house girder connection, be particularly useful for the reinforcing of precast hollow slab and standard width of a room in an old-style house girder connection in the masonry structure.
Background technology
According to brick masonry structure schoolhouse in the Wenchuan earthquake being collapsed Mechanism analysis and to the analysis of the existing masonry structure schoolhouse antidetonation investigation result in Xuzhou City with gather and can find out, the basic reason that masonry structure collapses is summed up as the characteristic of its materials used and the globality of structure itself.The masonry structure schoolhouse is owing to the architectural composition requirement of itself, and just existence in the sky earlier is unfavorable for the factor of antidetonation.Big at the masonry structure material fragility, not under the situation of malleable, valid approach is exactly the globality that strengthens structure.
Summary of the invention
The objective of the invention is to overcome the weak point in the prior art, provide a kind of simple to operate, strengthen structural integrity, resistance to deformation and method of attachment that effectively imbed steel reinforcing precast hollow slab and standard width of a room in an old-style house girder connection.
The method of attachment of imbedding steel reinforcing precast hollow slab and standard width of a room in an old-style house girder connection of the present invention; The two piece precast hollow slabs front and back bilateral symmetry relative in standard width of a room in an old-style house beam both sides are offered the groove that length is L; In the groove that symmetry is offered, be provided with respectively two precast hollow plate levels cross-under reinforcing bar together; Middle part between two precast hollow slabs is provided with and tilts to intersect the reinforcing bar that is X-shaped then; On the middle part standard width of a room in an old-style house beam between two precast hollow slabs, water pea gravel concreten afterwards, spread the thick pea gravel concreten of one deck 20mm at precast hollow slab and standard width of a room in an old-style house beam junction at last.
The diameter of described reinforcing bar is 8mm; The length L that said precast hollow slab front and back bilateral symmetry is offered groove is 500mm.
Beneficial effect: the present invention is through the reinforcement to connected node; Increase the globality of precast hollow slab and standard width of a room in an old-style house girder connection; Improve the cooperative transformation ability of each lateral resistant member, reduce the relative storey displacement of structure, thereby avoid the part of masonry structure or integral body to collapse as far as possible.Connecting reinforcement reinforcing precast hollow slab is imbedded in utilization and standard width of a room in an old-style house girder connection is simple, convenience, effective, can strengthen the tension and the shear-carrying capacity of node, reaches the purpose of reinforcing.
