Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and the following embodiments are used to illustrate the present utility model.
As shown in fig. 1 to 4, a novel two-way superimposed sheet of rib is not gone out on four sides, including prefabricated bottom plate 1, prefabricated bottom plate 1 top all is provided with a plurality of equidistance and distributes precast concrete stiffening rib 2, and precast concrete stiffening rib 2 all sets up a plurality of preformed holes 3 that are the equidistance and distribute with prefabricated bottom plate 1 top junction, and prefabricated bottom plate 1 all sets up recess 4 of certain length all around, and has placed post-positioned additional reinforcing bar 6 in the recess 4, has pour a plurality of hanging nails 5 above the precast concrete stiffening rib 2.
As shown in fig. 1 to 3, in the embodiment, the prefabricated base plate 1 is thin in overall thickness and the concrete is placed over the prefabricated base plate 1. In this setting, according to the floor span difference, generally 30-50mm, the prefabricated concrete square volume of component is less to guaranteed prefabricated bottom plate 1 can not take place the bending. The precast bottom plate 1 is provided with precast concrete stiffening ribs 2 along the long span direction of the plate. In this setting for overall rigidity and bearing capacity are bigger, and the anti cracking ability is strong.
As shown in fig. 1 to 3, further, the prefabricated floor panel 1 and the prefabricated concrete stiffener 2 use fewer reinforcing bars. In this setting, the truss reinforcing bar of traditional superimposed sheet has been cancelled, only prefabricated bottom plate 1 and precast concrete stiffening rib 2 arrangement of reinforcement, and whole reinforcing bar quantity is few. Reinforcing steel bars are arranged around the prefabricated bottom plate 1, and the reinforcing steel bars cannot be out. In this setting, the progress of component production has been accelerated, the efficiency of component transportation has been promoted, has showing and has improved on-the-spot superimposed sheet installation effectiveness.
As shown in fig. 1 to 3, further, grooves 4 are formed around the prefabricated base plate 1, and rear additional steel bars 6 are arranged at the grooves 4. In this setting, because system bottom plate 1 sets up recess 4 all around, the prefabricated bottom plate thickness in recess 4 bottom is the reinforcing bar protection layer thick, and recess 4 sets up the continuous transmission of rear-mounted additional reinforcing bar 6 can realize the moment of flexure. Compared with the traditional prefabricated laminated slab, the method for adding additional reinforcing steel bars on the top of the prefabricated slab has the advantage that the risk of cracking the bottom of the closely spliced portion is lower. The sizes of the precast concrete stiffening ribs 2, the preformed holes 3 and the grooves 4 all meet the modulus requirement, and the periphery of the precast bottom plate 1 is not ribbed. In this setting, component production mould turnover is high, and manufacturing cost further reduces. The superimposed sheets are connected in a closely spliced manner. In this setting, adopt close piece together formula connection between the superimposed sheet, cancelled the integral post-cast strip between traditional two-way superimposed sheet, only need set up a small amount of supports, further simplified the process.
The implementation principle of the novel two-way laminated slab with no ribs on four sides in the embodiment is as follows: pouring concrete of the prefabricated bottom plate, transporting the prefabricated bottom plate reaching the design strength to an assembly construction site after maintenance, hoisting in place, and placing a rear additional steel bar in the groove; and step two, pouring laminated layer concrete on the surface of the prefabricated bottom plate in the step one after the pipeline of the prefabricated bottom plate in the step one is buried, and curing the laminated layer concrete to reach the design strength, wherein the design strength can be referred to the existing design specification. And step two, in the process of pouring the laminated layer concrete, the laminated layer concrete enters the grooves and the rear-mounted additional steel bars are fixed.
