Abstract
The invention relates to a floor slab with cast-in-place concrete filling permanent core modules and a construction method thereof. The floor slab structurally comprises beams and the filling permanent core modules, reinforcing steel bars of the beams are longitudinally and horizontally tied on a lower layer of reinforcing mesh, the filling permanent core modules are arranged in the area defined by the reinforcing steel bars of the longitudinal and horizontal beams, an upper layer of reinforcing mesh is tied on the filling permanent core modules and the reinforcing steel bars of the beams, and the reinforcing steel bars and the filling permanent core modules are buried in concrete. The construction method includes the following steps: (1) the floor slab is designed, the positions of the beams are determined, the specification of the filling permanent core module is then determined, and the filling permanent core modules are produced; (2) a formwork is laid, and the formworks of the visible beams do not need to be laid; (3) the lower layer of reinforcing mesh is tied; (4) the reinforcing steel bars of the beams are longitudinally and horizontally tied on the lower layer of reinforcing mesh; (5) two, three, four or more filling permanent core modules are arranged in the area defined by the reinforcing steel bars of the beams according to design requirement; (6) the upper layer of reinforcing mesh is tied on the filling permanent core modules and the reinforcing steel bars of the beams; (7) concrete is poured; (8) the formwork is dismantled. The structure of the floor slab is simple and reasonable, construction is convenient, and a form of large-span floor slab is provided.
Description
Technical field
The invention belongs to building field, refer more particularly to the floor structure of large span.
Technical background
At building field, along with large-span steel-reinforced concrete structure floor structure is increasing, also emerge numerous innovative technologies in the hollow floor cover plate field, the technology of two-way slab particularly, vertically, laterally can arrange and fill permanent core part, solve the problem of shearing resistance by rib, and such hollow floor cover plate needs bright beam to support the problem with shearing resistance.The construction inconvenience of rib and bright beam, take out the concrete rate not high.Solve the shearing resistance problem by strangling, do not spread steel mesh reinforcement above filling permanent core part, floor structure is easy to crack to leak.Bright beam brings inconvenience also can to supporting process, as fire engineering and central air-conditioning pipe laying, increases engineering cost, and bright beam also increases the utilization in floor height restriction person space.
Summary of the invention
The present invention discloses floor structure and the job practices thereof of the permanent module of a kind of cast-in-place concrete filling, solve the deficiency that rib and Ming Liang take out the not high and bright beam of concrete rate, a kind of building floor structure form and job practices that meets the permanent core part of Concrete Filled of mechanics principle, easy construction is provided.
The technical solution used in the present invention is, the floor structure of the permanent core part of a kind of cast-in-place concrete filling, comprise beam and permanent core part, it is characterized in that: the reinforcing bar of vertical and horizontal colligation beam on lower floor's steel mesh reinforcement, the reinforcing bar of vertical and horizontal beam surrounds the permanent core part of area filling, colligation top mat on fill permanent core part and on the reinforcing bar of beam, in reinforcing bar and the embedding concrete of the permanent core part of filling.
The job practices of the floor structure of the permanent core part of cast-in-place concrete filling is characterized in that:
(1), the design floor structure, the position of reserving beam, more surely fill the specification of permanent core part, produce and fill permanent core part;
(2), tiling template;
(3), colligation lower floor steel mesh reinforcement;
(4), the reinforcing bar of vertical and horizontal colligation beam on lower floor's steel mesh reinforcement;
(5), the area arrangement that surrounds at the reinforcing bar of beam fills permanent core part, two, three, four etc. by designing requirement, arrange;
(6), colligation top mat on fill permanent core part and on the reinforcing bar of beam;
(7), concreting;
(8), stripping.
After adopting such scheme, the present invention has following beneficial effect compared with prior art:
Because top mat has been arranged, pull resistance strengthens, and floor structure is not easy cracking; Top mat is arranged, and rib and beam are able to combination, no longer adopt bright beam, beam combines in length and breadth, and amount of reinforcement reduces, and fills the more intensive of permanent core part arrangement, meet the technological requirement that once-pouring of concrete is shaped, greatly accelerate the construction speed of floor structure, take out the concrete rate and improve.Adopt floor structure of the present invention, net post is wide, and floor height lowers, and better utilizes space; Conveyance system is designed and constructed easily and fast, cost reduction.
The accompanying drawing explanation
The sectional view that Fig. 1 is floor structure lateral cell of the present invention;
The sectional view that Fig. 2 is the vertical unit of floor structure of the present invention;
Fig. 3 is that the permanent core part of filling of the present invention is arranged and beam steel surrounds structural representation.
The specific embodiment
The structure of accompanying drawings floor structure of the present invention
The reinforcing bar 1 of lower floor's steel mesh reinforcement is arranged closeer than the reinforcing bar of top mat 2, the zone that the reinforcing bar 3 of longeron and the reinforcing bar 4 of crossbeam surround is arranged and is filled permanent core part 5, the reinforcing bar 2 of top mat and the reinforcing bar 1 of lower floor's steel mesh reinforcement are just the reinforcing bar 4 of the reinforcing bar 3 of longeron, crossbeam with fill permanent core part 5 and clamp, and concrete 6 waters them to have buried.
The job practices of the floor structure of the permanent core part of this cast-in-place concrete filling is:
(1), the design floor structure, the position of reserving beam, more surely fill the specification of permanent core part, produce and fill permanent core part;
(2), the tiling template, the template that need not lay bright beam;
(3), colligation lower floor steel mesh reinforcement;
(4), the reinforcing bar of vertical and horizontal colligation beam on lower floor's steel mesh reinforcement;
(5) area arrangement surrounded at the reinforcing bar of beam is filled permanent core part, two, three, four etc. by designing requirement, arranges;
(6), colligation top mat on fill permanent core part and on the reinforcing bar of beam;
(7), concreting;
(8), stripping.
The present invention is simple and reasonable, and easy construction provides a kind of form of long-span floor system plate.
