Description
Technical field
The utility model relates to technical field of buildings more particularly to a kind of hollow floor concrete for having anti-floating function
Protective layer cushion block.
Background technique
Cast-in-place concrete hollow building roof construction technology is the domestic new technology to grow up in recent years, with solid concrete building
Lid, which is compared, to be had many advantages, such as from heavy and light, span is big, rigidity is good, sound-insulating and heat-insulating is good, cost is relatively low, has been particularly suitable for opening greatly
Between, large span require architectural engineering.Due to cast-in-place concrete from heavy and light and also quantity it is more, generate buoyancy in concreting
Effect, solution is bad, and less serious case causes local floor absolute altitude superelevation, reduces finishing way thickness, and severe one will cause large area floating
There is quality accident.
The anti-floating of existing filled internal mold is fixed by the iron wire of diameter 3-5m.When fixed anti-floating control point, first by iron wire one end
It is pierced by down from hole in template, iron wire end is up worn back from hole after being tied with the support system of template, works as peace
It puts filled internal mold well, bound on plate after iron and distributing reinforcement, two ends of iron wire are tightened at anti-floating control point, prevent from filling out
Fill internal model floating.There are a large amount of iron wires for concrete floor bottom surface after such method template is removed, and influence floor later period decoration dress
It repairs.Therefore, how to develop one kind energy free of demolition to consolidate hollow floor to determine the concrete protective layer pad of baseplate reinforcing bar mesh sheet is this
Field technical staff vomits technical problem to be solved.
In conjunction with the present Research that current cast-in-place concrete hollow building roof is constructed, incorporation engineering actual features are to cast-in-place concrete
Hollow floor concrete protective layer pad optimizes, the technical problem to be solved by the utility model is to: in existing filling
The anti-floating of mould is fixed by the iron wire of diameter 3-5mm, after such method template is removed concrete floor bottom surface there are a large amount of iron wire,
Influence the decorations of floor later period.
Summary of the invention
For the above-mentioned deficiency of the prior art, the technical problem to be solved by the utility model is to be proposed a kind of hollow
The superstructure concrete protective layer pad for having anti-floating function, for solving local floor absolute altitude superelevation, large area floating etc. is asked
Topic.
The utility model solves its technical problem the technical solution adopted is that a kind of hollow floor, which is used, has anti-floating function
Concrete protective layer pad, which is characterized in that the cushion block is equipped with the beading for stretching out cushion block top preset height and bending, described
Cushion block is additionally provided with the steel nail of at least two stretching cushion block lower parts.
Preferably, the dogleg section of the beading is horizontally disposed.
Preferably, the end of the beading is equipped with crotch.
Preferably, the crotch is bent 180 degree down.
Preferably, all steel nails are connected with beading.
The utility model be suitable for cast-in-situ hollow building roof by the horizontal beading with concrete pad one by bottom steel
Muscle mesh sheet is fixedly secured in bottom plate, which fixes baseplate reinforcing bar mesh sheet by beading, then hollow-core mould top
Anti-floating additional muscle by iron wire and baseplate reinforcing bar mesh sheet drawknot, the resistance to plucking of end template generation is hammered by the steel nail of cushion block bottom
Power resists buoyancy of hollow-core mould during casting concrete, achievees the purpose that controlling hollow-core mould floats；It prevents hollow
Core model floats during casting concrete.Bed die and support for shuttering drawknot stationary phase ratio, concrete are passed through with traditional iron wire
Cushion block bottom steel nail hammers into end template, not only can control protective layer thickness but also has been capable of fixing baseplate reinforcing bar mesh sheet, has greatly reduced tradition
The fixed labor intensity of mode, saves a large amount of iron wires, and the remaining iron wire that processing traditional approach leaves is not needed after demoulding, existing
Pouring concrete hollow floor Forming Quality is excellent.By improving cushion block, conventional concrete cushion block function was not only played, but also be capable of fixing bottom
Layer reinforced mesh replaces the existing way being fixed on support for shuttering steel pipe in template turn hole iron wire.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
Fig. 1 is please referred to, the utility model discloses a kind of hollow floor concrete protective layer pad for having anti-floating function,
It is characterized in that, the cushion block 100 is equipped with the beading 110 for stretching out 100 top preset height of cushion block and bending, the cushion block 100
It is additionally provided with the steel nail 120 of at least two stretching cushion blocks, 100 lower part.
Specifically, the beading 110 has stretching certain high from 100 cushion block of concrete protective layer pad, 100 center upper portion
Spend simultaneously transverse fold.The lower end of the steel nail 120 is tapered, and in this embodiment, the ontology of the cushion block 100 is in cuboid
Shape.The cushion block 100 can also be the square bodily form, cylinder, quincunx or all other shapes that can pile up.
100 ontology of cushion block can be by high-intensitive mixed mud, fine sand concrete, cement mortar, high molecular material (as moulded
Material), one of other high-strength materials or a variety of be mixed.
The buoyancy of hollow floor core model is resisted by the bond stress that 100 lower part steel nail 120 of cushion block hammers into template.
Preferably, the dogleg section of the beading 110 is horizontally disposed, can facilitate so solid with the bottom reinforcement bars of cassette ceiling
It is fixed.
Preferably, the end of the beading 110 is equipped with crotch 111.Cushion block 100 is guaranteeing reinforcement protective layer thickness
Meanwhile the horizontal beading 110 by top with hook by the bottom reinforcement bars of cassette ceiling toward being fixedly secured in the template of bottom.
Preferably, the crotch 111 is bent 180 degree down, and in this embodiment, the crotch 111 is bent 180 down
