Abstract
The utility model discloses a prestressing force light irregular section internal filling module which consists of internal module upper layer distributed reinforcing steel bars (1), light material internal module position-limit reinforcing steel bars or cushion blocks (2), internal module upper layer carrier reinforcing steel bars (3), a light material internal module (4), internal module lower layer carrier reinforcing steel bars (5), bearing rods (6), prestressed bars (7) and internal module lower layer distributed reinforcing steel bars (8). The section of the light material internal module is in various shapes except round and rectangle, such as oblong, polygon, and the combined shape of round and rectangle. The structural form is used to provide large span and to reduce the self gravity of the structure at the same time; the structure has good effects of earthquake resistance, crack resistance, sound insulation and heat insulation; the prestressing force light irregular section internal filling module has very good economic performance and applicability.
Description
Technical field
The utility model belongs to buildings in general structure field.
Background technology
At building field, along with increasing of longspan structure, the technology that increasing cast-in-place plate adopts prestressing force to combine with light material.Prestressed reinforced concrete construction can increase the span-depth radio of horizontal member, can improve deformation of members and cracking resistance and non-deformability simultaneously.Light material plate and solid slab structure specific energy mutually alleviate dead load.Present existing technology mainly is divided into two big classes: (1) circular hollow tube, (2) light material Filled Rectangle.This two classes material uses all certain limitation.Therefore study a kind of novel filled internal mold for being badly in need of.
Summary of the invention
The purpose of this utility model provides a kind of prestressed light profiled-cross-section filled internal mold.It is made of plate upper strata distribution reinforcement, the spacing reinforcing bar of light material filler or cushion block, plate upper strata steel bar stress, light material filler, plate lower floor steel bar stress, bearing rod, presstressed reinforcing steel and plate lower floor distribution reinforcement.The utility model adopts profiled-cross-section to solve the problem that improves hollow rate, by the improvement of section form, the soffit of filling block is designed to circular arc or broken line shape, is convenient to concrete flowing; Adopt light material to fill and solve the problem that alleviates member dead weight, adopt prestressing technique can solve the large span problem.The cast-in-place plate of this kind is taken into account the advantage of pre-stress hollow tubular structure and square-section light material infill panel, and convenient construction under the prerequisite that keeps higher hollow rate is realized the moulding of concrete primary concreting.The cast-in-place span of slab of this kind is big, deadweight is little, sound insulation, good heat-insulation effect, and reliability of structure, shock resistance, crack resistance are also better.The utlity model has excellent economy and applicability, the development of Building technology is played a driving role.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a transverse cross-sectional view of the present utility model, with reference to this figure, the utility model is made of internal mold upper strata distribution reinforcement (1), the spacing reinforcing bar of light material internal mold (2) or cushion block, internal mold upper strata steel bar stress (3), light material internal mold (4), internal mold lower floor steel bar stress (5), bearing rod (6), presstressed reinforcing steel (7) and internal mold lower floor distribution reinforcement (8).
Fig. 2 is light material internal mold (a 4) cross-sectional configuration schematic diagram in the utility model, and its cross sectional shape has ellipse (9), polygon (10), circular and rectangle composite figure (11).
The specific embodiment
The utility model is to realize in such a way:
As internal mold, adopt prestressing technique with light material simultaneously, large span both is provided, alleviate dead load again.Used presstressed reinforcing steel (7) both can be not have bonding, also bonding can be arranged.Light material internal mold (4) cross section had been not only non-circular, but also non-rectangle, for the ease of the concrete one-time-concreting, the soffit of internal mold was designed to circular arc; According to the design and construction needs, form of fracture can adopt multiple shape as oval (9), polygon (10), circular and rectangle composite figure (11).Light material internal mold (4) can adopt profiled-cross-section hollow section or solid porous foamed light material.The cast-in-place plate of this kind both can be used as one-way slabs, also can be used as two-way slab.The come-up of light material internal mold (4) is spacing can use reinforcing bar, also can be at internal mold napex colligation cement or plastic cushion.The utility model realization order: colligation plate lower floor reinforcing bar-colligation bearing rod-colligation presstressed reinforcing steel-lay and fixing light material internal mold-colligation internal mold top reinforcement-wear the spacing reinforcing bar of internal mold or lay cushion block.
