Abstract
A kind of height-adjustable precast concrete laminated floor slab, including angle steel, soft material, steel bar girder, L-shaped lead screw, concrete and nut.Concrete and steel bar girder pour the component A1 for building up both sides hole in factory jointly, and grooved bore angle steel is placed on the bottom of component A1 in a manner of hole aligning.The montant of live L-shaped lead screw passes through hole on component A1 and angle steel and is tightened by nut, and cross bar hanging is in the upper surface of beam when lifting.The height for adjusting prefabricated board after lifting by the nut adjusted on L-shaped lead screw, adjusts the relative position of floor and beam, ensures that each piece of slab surfaces are concordant, solves the assembly problem that surface of concrete structure injustice is brought.Prefabricated board and angle steel serve as bed die, and spillage is placed in soft material blind, convenient for pouring for last layer.The stealthy part deck-molding of floor, increases the clear height of structure sheaf.Steel bar girder in prefabricated board enhances the cohesive force of new and old pouring layer, improves the globality of laminated floor slab.
Description
Technical field
The invention belongs to building structural element fields, are suitable for assembling type steel structure and build.
Background technology
In the case that in China, annual output of steel is excessive, a series of popularization steel have been carried out in building structure by country
The policy used, greatly develops steel building.Steel construction is good from heavy and light, plasticity and good toughness and anti-seismic performance by it
The advantages that development it is swift and violent, the assembling type steel structure system come into being has that speed of application is fast, construction pollution is few, quality easily ensures
The advantages that, it is a kind of " green " building, is suitable for the development of Building Trade in China, the construction industry in China is made to return industrialization.
Precast concrete laminated floor slab refer to bottom use precast concrete thin plate (thick 5cm-8cm) for permanent formwork with
Top in-situ layer overlaps and the assembled integral floor of formation, this laminated floor slab have good integrity, the rigidity of cast-in-situ floor
Greatly, crack resistance is good, does not increase reinforcing bar consumption, saves the advantages that template, can be built in a manner of prefabrication and assembly construction to the full extent, generation
The table developing direction of national building industrialization, existing precast concrete laminated floor slab have the following disadvantages：
1) laminated floor slab is placed on by the peg or bolt for being welded on beam top flange on beam, and entire deck-molding is exposed to outer
Face reduces the clear height of structure sheaf, and influences beautiful.
2) laminated floor slab piecemeal completes lifting, and slab surfaces are not concordant after being susceptible to lifting.
The present invention combines the form of existing laminated floor slab, and a kind of novel precast concrete overlapping is proposed for its drawback
The form of floor.After lifting, last layer adjusts the height and position of prefabricated board before pouring, ensure the surface of each piece of floor after lifting
Concordantly；It is acted on using the suspension of L-shaped lead screw, by part deck-molding " stealth ", increases the clear height of structure sheaf, enhance floor and beam
Globality reduces unnecessary waste of material, keeps the space layout of structure more flexible, beautiful；Made with angle steel and prefabricated board
For bed die, soft material fills the gap between angle steel and beam web, and the formwork convenient for laminated floor slab last layer pours；Prefabricated board
The reinforcing bar of interior truss form not only increases the cohesive force of the new and old pouring layer of laminated floor slab, improves the shear resistance of floor,
And it is embedded convenient for pipeline, avoid secondary trepanning.
Invention content
The present invention proposes a kind of height-adjustable precast concrete laminated floor slab form, it is therefore intended that overcomes existing
The technological deficiency of laminated floor slab improves the assembly precision of component, the applicable model of expandable member while ensureing that structure is safe and reliable
It encloses.
Technical scheme is as follows：
1, a kind of height-adjustable precast concrete laminated floor slab, it is characterised in that：Shown laminated floor slab includes：Angle steel
(1), soft material (2), steel bar girder (3), L-shaped lead screw (4), concrete (5), nut (6)；
2, above-mentioned steel bar girder (3) is distributed in the bottom of concrete (5) as principal rod, concrete (5), steel bar girder
(3) along beam direction both sides reserving hole member of formation A1 when the two one-piece casting；
3, on angle steel (1) with the corresponding positions component A1 cutting elongated groove hole, soft material (2) is pasted onto angle steel short side side
Form component A2；
4, component A2 is placed on the bottom of component A1 in a manner of hole aligning, and the montant of L-shaped lead screw (4) passes through component A1
With the hole of A2, and tightened by nut (6).
5, component A1 and component A2, L-shaped lead screw (4), nut (6) lift together, and the cross bar of L-shaped lead screw (4) is hung in beam
Upper surface.
6, above-mentioned L-shaped lead screw (4) has multiple, is equally distributed on beam slab connection both sides, and the cross bar of lead screw should have foot
Enough length is suspended on ensureing to stablize floor in lifting on two curb girders.
Soft material:Sponge may be used, rubber etc. can deform the material of stickup.
Slot:Deformation for soft material in beam vertical direction provides space, and it is short to ensure that soft material is filled up completely angle steel
Gap between side and beam, not spillage when ensureing that last layer branch side form pours.
Advantageous effect
A kind of height-adjustable precast concrete laminated floor slab form of the present invention, has the prominent advantages that:
1) assembly precision of floor is improved, the height of precast floor slab can adjust, and each piece of floor of flexible modulation is hung in making
Difference in height when dress ensures that the lower surface of each floor after lifting is concordant.
2) by adjusting the height and position of precast floor slab, the relative position of in-situ layer and beam is adjusted.
3) L-shaped lead screw can play the role of bearing floor shearing in service stage.
4) laminated floor slab is suspended on beam, and stealthy part deck-molding enhances the globality of beam slab, increases the net of structure sheaf
Height keeps the arrangement of structure more flexible, beautiful.
5) bed die is served as using angle steel and prefabricated board, soft material fills gap between angle steel and beam web, convenient for overlapping
Floor slab back casting layer pours.
6) steel bar arrangement of truss form increases the cohesive force of floor superposed surfaces, improves the overall performance of floor, especially
It is shear resistance.
