Description
Technical field
The present invention relates to a kind of cushion block of concrete bar protective layer structure and its installation method, especially suitable for reinforced concrete structure
The thickness of protection tier of side, bottom surface especially inclined plane is not easy the region ensured.
Background technology
The reinforced concrete structure structure type maximum as the scale of construction in civil engineering, it is gradual the problem of its durability deficiency
It is exposed, substantial amounts of works is far from reaching design life, and steel bar corrosion, concrete scaling etc. just occur serious
The problem of influenceing structure applicability, security.Substantial amounts of engineering practice both at home and abroad shows that thickness of protection tier is relatively low and discrete
Bigger than normal is one of most important factor, and a large amount of theory analysises show the time of steel-bar corrosion and square of protective layer thickness
It is proportional, if if the steel bar corrosion time limit corresponding to protective layer thickness thick 1cm is 10 years, the concrete of equal quality, 2cm
The steel bar corrosion time limit corresponding to thick protective layer thickness is exactly 40 years.
Protective layer thickness is locally too small in entity structure, mainly protective layer cushion block quantity is few or cushion block colligation loosely,
Do not play a part of spacer bar.Reinforcement ratio comparatively dense, the smaller works of protective layer design thickness, padded mostly using star
Block, and the existing fixed form of star cushion block has two classes, one kind is that cushion block colligation is existed through the circular hole in cushion block center with tied silk
On reinforcing bar, one kind is in one clip of cushion block end set in addition（Metal clip or plastic clip）, cushion block is directly arranged on steel
On muscle.Above-mentioned two classes fixing means, all no to solve the problems, such as that cushion block rotates around reinforcing bar, cushion block once rotates, and protects
Thickness degree will diminish, or even vanishing.Small for local radius of curvature, bar spacing is small, the armored concrete knot more than the number of plies
Structure thing, the cushion block on the bottom plate of scattered fixation, easily turns on one's side at the construction field (site), the cushion block of fixed side, easily around steel
Muscle rotates.The cushion block of scattered fixation, in the event of rollover or rotation, it cannot often be corrected before concreting,
Some are to correct, and some are to have little time to correct.
As can be seen here, prior art is up for further improving.
The content of the invention
In place of the present invention is avoids above-mentioned the shortcomings of the prior art, there is provided a kind of cushion block of concrete bar protective layer structure and
Its installation method.
The technical solution adopted in the present invention is：
A kind of cushion block of concrete bar protective layer structure, including the first cushion block and the second cushion block, the first cushion block and the second cushion block are in
It is hemispherical, offer the first groove, first, second cushion block along respective diametric(al) on the top end face of first, second cushion block
The side of top end face offer two the second grooves that are vertical with the first groove and communicating, be not provided with second on the first cushion block
The side of groove is connected with being not provided with the side of the second groove on the second cushion block for reversible, and second is provided with the first cushion block
Button Block is provided with the outer surface of the side of groove, is provided with the outer surface for the side for being provided with the second groove on the second cushion block
It is adapted with Button Block and buckle that position is relative, the upset of first, second cushion block can makes buckle be caught in Button Block after fastening, the
First, after the upset of the second cushion block fastens, the first groove of first, second cushion block, which cooperatively forms, is capable of the reinforcing bar of clamping reinforcing bar and houses
Groove, the second groove of first, second cushion block are respectively cooperating with forming two filling slots.
The side that the second groove is not provided with first cushion block leads to being not provided with the side of the second groove on the second cushion block
Cross pin-jointing piece to be connected, pin-jointing piece can be along the center line doubling of its own.
The section of the pin-jointing piece is U-shaped, and one end of pin-jointing piece is connected with the first cushion block, the other end is consolidated with the second cushion block
Even, and after connection, the top end face of pin-jointing piece is concordant with the top end face of first, second cushion block respectively.
The Button Block center offers the port passed through for buckle, and one end of buckle is connected with the second cushion block, the other end is set
It is equipped with crotch.
The buckle, Button Block and pin-jointing piece are each made of a metal.
First groove is in semi-cylindrical, and the internal diameter of the first groove is more than the nominal diameter of reinforcing bar.
First, second cushion block is made by mortar.
The invention also discloses a kind of installation method of cushion block of concrete bar protective layer structure as described above, this method is included such as
Lower step：
Step 1, according to the arrangement requirement of cushion block of concrete bar protective layer, the first cushion block, which is placed on, makes its first groove and reinforcing bar
The consistent position of length direction；
Step 2, the second cushion block is overturn, it is fastened on the first cushion block；
Step 3, first, second cushion block after rotational installation, checks whether buckle is closely fastened on Button Block；If there is pine
It is dynamic, the crotch of buckle one end is rolled over again to ensure that buckle does not release；
Step 4, during concreting, filled by filling slot into first, second cushion block water slurry silt to fill up first,
Gap in second cushion block, ensure that both do not rotate around reinforcing bar.
By adopting the above-described technical solution, having the beneficial effect that acquired by the present invention：
Protective layer cushion block in the present invention can not only play a part of spacer bar, and first, second cushion block fastens
Both position is relatively fixed afterwards, fills up space position between the two with water slurry silt in concreting, effectively
Prevent cushion block to be rotated around reinforcing bar, while ensure that thickness of protection tier, shorten the construction time.
