Description
Technical field：
The utility model is related to concrete working device field, more particularly to a kind of concrete extension joint joint filling device.
Background technology：
In the construction on mattess or road surface, Crack Control is always the emphasis link of concrete construction control.Especially
It is to be easiest to cause the generation in crack when temperature change and concrete shrinkage cause the excessive additional internal stress of structure, for
Measure that there are mainly two types of this additional internal stress controls, one is：Constraint both carried out arrangement of reinforcement to concrete structure；Another kind is just
It is：It dredges, seam is mainly set in concrete plate.The form of seam will have three kinds of expansion joint (E.J.), contracting seam and construction joint, and
Construction joint is generally arranged at expansion joint (E.J.) and contracting seam, briefly there was only two kinds of expansion joint (E.J.) and contracting seam by structure type.Expansion joint (E.J.) is generally wide
20-30mm is spent, top half 3-4cm uses gap filler joint filling, lower part to use joint filling board joint filling.Contracting seam be generally baste, be
3-8mm wide is cut on the top of concrete plate, then the seam of depth about 5-6cm pours gap filler in seam.
In actual use, both seams are very limited for release internal stress effect, and tape edge edge
Concrete be easily destroyed, gap filler be detached from, stitch in enter a large amount of sundries, to concrete structure internal stress discharge again cause
Certain obstruction, concrete plate damage accelerate, and later period maintenance is costly.
Utility model content：
The utility model aims to solve at least one of the technical problems existing in the prior art.
For this purpose, its technical scheme applied to solve the technical problem of the utility model is：Concrete extension joint joint filling device,
Including：Connecting plate, connecting plate are made of upper junction plate and lower connecting plate, and upper junction plate passes through spiral shell by 2 pieces in the band steel of strip
Bolt is composed, and the both sides of upper junction plate are also respectively welded a large amount of anchoring pegs, and lower connecting plate includes upper and lower 2 pieces of connections steel
Plate is welded with one piece of horizontally disposed force transmitting board between 2 pieces of junction steel plates, and the side of force transmitting board is arranged with guide, upper junction plate
It is welded in the top surface of lower connecting plate.
Preferably, the cross section of 2 pieces of band steels is rectangle, and rectangular long side is in be vertically arranged.
Preferably, largely anchoring the middle part of the evenly spaced both sides upright side walls for being welded in upper junction plate of peg.
Preferably, the angle of anchoring peg and horizontal plane is 10 °~20 °.
Preferably, junction steel plate include in vertical web and take shape at the top and bottom of web in horizontal
Wing plate, junction steel plate are C-type steel or H profile steel or U-shaped steel.
Preferably, the wing plate at the top of two pieces of junction steel plates and the wing plate of bottom are respectively welded in the middle part of force transmitting board
Top and bottom.
Preferably, guide forms inner cavity, the width of the cross section of inner cavity is more than the 1/2 of force transmitting board width.
Preferably, bolt is plastic bolt.
The beneficial effects of the utility model are：
The utility model is placed before concreting, and multiple the utility model can be arranged to across or T-shaped
Or other desired shape discharge, every seam is all made of two pieces of band steels after concreting, and band steel is fixed by plastic bolt
Together, anchoring peg also anchors in concreting process in concrete plate, and two band steel lower welds have company
Connect steel plate, on the one hand junction steel plate is used as the template in construction, on the other hand play the role of fixing force transfer plate, force transmitting board with connect
Steel plate welds together, and the upper installation guide in force transmitting board side allows a part for force transmitting board effect of expanding with heat and contract with cold to exist
It is completed in guide, force transmitting board is used to transmit the vertical load of the adjacent both sides plate in expansion joint so that the height difference position of seam both sides plate
Shifting reaches minimum, to be formed because of the difference of height that uneven stress and subsiding belt are come, after concrete curing, is dried and shrinks
The plastic bolt of fixed flat steel will be broken, so that two band steels is separated, be located on adjacent concrete plate, to shape
At expansion joint, expansion joint allow concrete plate divide storehouse block, both direction in length and breadth with the four seasons variation of ambient temperature freedom
It is flexible, it is greatly reduced the damage of concrete plate, reduces later maintenance expense.
