Description
Technical field
The invention belongs to technical field of building construction, specially a kind of cushion block.
Background technology
With developing rapidly for building trade, the usage amount of cushion block is also more and more huger in concrete construction.Building trade
Construction level quickly grow, it is varied that the form of cushion block also becomes, but its purposes and basic manufacture craft be not all too big
Change.
Concrete pad is called cushion block of concrete bar protective layer, is in brick mix structure and in frame structure, be placed on reinforcing bar and
Between template, fixed reinforcement location, to the effect for preventing reinforcing steel bars exposed and being corroded, is to solve reinforcing bar to fix conventional do
Method.As shown in Figure of description Fig. 1.
But common cushion block is smaller due to size, mainly for ensuring protective layer thickness, some tie up complete not yet on reinforcing bar
It is complete fixed, skew is easy to during casting concrete ineffective.
Still need specially to make stirrup reinforcing bar during most of reinforced concrete structure assembling reinforcement and carry out spacer bar skeleton, have
Although a little cushion blocks have supporting role, can replace stirrup reinforcing bar, but are due to that size is fixed, and applicability is poor.Practice of construction
In, reinforcing bar colligation conflict local or higher, lower space all can not specification colligation cushion block, or damage by pressure,
It is hanging, effect is not all had much yet.Refer to Figure of description Fig. 2 to Fig. 4
In addition, cushion block uses concrete for making, material cost is high, slow in intensity.
Therefore, research and development are a kind of can adjust height, what the cost of material is low, and the cushion block of good fixing effect is needs of the present invention
The technical problem of solution.
The content of the invention
The present invention provides a kind of cushion block aiming at above-mentioned defect.The cushion block can adjust height and upper underlay
Angle between block so that framework of steel reinforcement support is more stablized, convenient and practical, building castoff is used for raw material, to reduce
Cost and energy-conserving and environment-protective.
A kind of cushion block technical scheme of the present invention is, including the upper cushion block and lower cushion block connected by adjustment bolt, described
Upper cushion block and lower cushion block can be rotated by axis of adjustment bolt；Upper cushion block upper end is provided with the upper card for supporting top bars
Groove, lower cushion block side is provided with the lower bayonet slot for supporting lower floor's reinforcing bar.
Upper neck runs through upper cushion block two relative side, and upper neck bottom is the arc to bottom notch, lower cushion block wherein one
Individual side is provided through the lower bayonet slot of the lower cushion block adjacent side in side two, upper surface that lower bayonet slot includes being sequentially connected, interior
Side and lower surface, lower bayonet slot upper surface is an openend higher than inclined plane with medial surface connection end, lower bayonet slot lower surface with
Medial surface connection end is provided with arc groove.
Described lower bayonet slot lower surface open side is horizontal plane.
The angle constituted between lower bayonet slot upper surface and horizontal plane is 10-60 degree.
Upper cushion block and lower cushion block are rectangular parallelepiped structure.
Upper neck width of rebate is more than the diameter of institute's spacer bar, and the Breadth Maximum of upper neck bottom arc, which is not less than, to be propped up
The diameter of reinforcing bar is supportted, the height of upper neck notch to arc minimum point is thick not less than the diameter and cover to reinforcement of institute's spacer bar
Spend sum.
Lower bayonet slot width of rebate is more than the diameter of institute's spacer bar, minimum point the hanging down to upper surface of lower bayonet slot arc groove
Straight distance is not less than the diameter of institute's spacer bar, and lower bayonet slot arc groove minimum point to the thickness between lower cushion block bottom surface is reinforcing bar
Protective layer thickness.
Upper cushion block and lower cushion block are relative in adjustment bolt to be moved up and down.
Described cushion block is prepared from by binder materials, aggregate and admixture, and wherein binder materials is cement, and aggregate includes
The granulated slag that the building castoff such as discarded concrete or discarded stone material is worn into, admixture includes flyash, slag powders.
Described cushion block is prepared from by following component by weight：20-30 parts of cement, aggregate 45-55, admixture
20-30, surplus is water.
The adjustment bolt can be standard bolt or customization bolt, and material can be metal, plastics or other hard
Material.
Proportionally then each raw material dry mixing is added water, stirred evenly to uniform.（The amount added water, agglomerating be to stir defensive position and grab
It is accurate）.Suppress and form in cushion block former after stirring.The preparation technology is simple, and curing period is short, and production efficiency is high.
In use, cushion block is placed on, lower floor's reinforcing bar is caught in lower bayonet slot.Using bolt adjust height and
Upper lower cushion block angle, top bars is caught in upper neck.So cushion block can play a part of controlling protective layer thickness again may be used
To support whole framework of steel reinforcement.Boxed out in the middle of upper cushion block lower surface and lower cushion block upper surface, pre-install M10（Or other models）
Bolt.Upper cushion block rotates a circle, and rises or decline 1.5mm（Correspondence bolt model）, meeting precision that cushion block highly adjusts will
Ask, to adapt to the floor or shear wall structure of different-thickness.Bolt any rotation can support reinforcing bar up and down staggeredly, and
Framework of steel reinforcement support is set more to stablize by adjusting height, practical is very strong.
Beneficial effects of the present invention are：
1. the cushion block is applied to the support of multistory reinforced skeleton, the fixation reinforcement location that can stablize, skew will not be produced, and
Designed, it is ensured that the thickness of concrete cover of floor plate bottom and plate face, can effectively controlled again according to rebar sizes and floor thickness
Thickness of concrete floor, force structure rationally, will not produce the problem of damaging by pressure and be hanging；
2. finely tuning upper height and angle between cushion block and lower cushion block using adjustment bolt, control protective layer thickness can be played
Effect can support whole framework of steel reinforcement again, bolt any rotation can support reinforcing bar up and down staggeredly, and pass through and adjust
Whole height makes framework of steel reinforcement support more stablize, and practical is very strong.
3. using building castoff for raw material, cost and energy-conserving and environment-protective are reduced, preparation technology is simple, and curing period is short, raw
Produce efficiency high.
