Description
Technical field
The utility model relates to a kind of clamping components, and in particular to a kind of elastic clamping unit.
Background technique
Reinforced concrete structure, with the meaning of milestone, makes building to more Gao Geng great across development in architectural development history.
With the extensive use and research of reinforced concrete structure, people also increasingly pay attention to knot while improving the intensity of structure
The durability of structure especially more payes attention to the durability of reinforcing bar.Influence reinforcing bar durability factor it is numerous, as environment category,
Chemistry of concrete ingredient etc. mainly passes through control reinforcing bar wherein the influence with environment to reinforcing bar durability is the most prominent in design
Protective layer thickness reduces influence of the environment to reinforcing bar.
In practical structures work progress, unit in charge of construction is often not in place to the protective layer thickness control measure of component, special
Be not the control to wall column thickness of protection tier, traditional plastic cushion or strip concrete pad in template installation by
It is easy to fall off when being shaken to worker's tapping template or deviation cannot be effectively to steel reinforcement cage especially when steel reinforcement cage height is larger
It is positioned, therefore very small to the effect on control wall column cover to reinforcement.Currently there are a kind of packaging type cushion block, edges
The receiving hole that the center line setting reinforcing bar of cushion block passes through, then opening up on the body of cushion block is that reinforcing bar enters opening for receiving hole
Mouthful, it is just not easy to fall off between such cushion block and reinforcing bar by the way that reinforcing bar to be embedded into receiving hole.But this cushion block is making
When, the diameter of receiving hole can not be accomplished accurately to control, once aperture is greater than bar diameter, it just will appear gap therebetween,
Cushion block can loosen on reinforcing bar, and then impact to the thickness of protective layer.
In order to solve the above-mentioned technical problem, inventor devises a kind of concrete reinforcement cushion block, including left and right is oppositely arranged
Left cushion block and right cushion block, be provided with mounting groove, the mounting groove on left cushion block on left cushion block and the opposite side side of right cushion block
Left elastic clamping unit is inside installed, right elastic clamping unit is installed in the mounting groove on right cushion block.Left elastic clamping unit includes a left side
The left bottom plate and left clamping plate that the right side is oppositely arranged are fixedly connected with two on left bottom plate and are parallel to each other and perpendicular to a left side for left bottom plate
Guide rod, left guide rod are passed through on left clamping plate, left guide rod and be arranged between left bottom plate and left clamping plate can
The left spring of spring force is provided for left clamping plate；Right elastic clamping unit includes the right bottom plate and right clamping plate that left and right is oppositely arranged,
It is fixedly connected with two on right bottom plate to be parallel to each other and perpendicular to the right guide sleeve of right bottom plate, right guide sleeve is passed through in right clamping
Plate, the position of right guide sleeve is corresponding with the position of left guide rod, left guide rod be inserted into corresponding right guide sleeve and with
It is slidably matched, and spring force can be provided for right clamping plate by being arranged on right guide sleeve and between right bottom plate and right clamping plate
Right spring.When use, reinforcing bar is placed between left clamping plate and right clamping plate, at the same be located at two left guide rods it
Between, then left guide rod is inserted in right guide sleeve, makes left clamping plate and right clamping plate respectively in the bullet of left spring and right spring
Reinforcing bar is clamped under spring force.But during adding to steel bar clamping, reinforcing bar still can be in left clamping plate and right clamping
It is deviated between plate, becomes larger or become smaller then accordingly will result in distance between cushion block outer surface and reinforcing bar, and then concrete is protected
The thickness of sheath impacts.

The both ends of spring are respectively fixedly connected on guide sleeve and bottom plate, and spring can be displaced outwardly to be located at guiding for guide sleeve
Body provides spring force far from one end end of bottom plate, and the side of guide sleeve towards adjacent another guide sleeve is provided with clamping plate, presss from both sides
One end of tight plate close to its side guide sleeve is hingedly connected together by hinged shaft and guide sleeve, the axis direction of hinged shaft
Plane where being parallel to bottom plate, two pieces of clamping plates are equal between two guide ways along the sum of length of two guide way relative directions
Length, linked together between two pieces of clamping plates by flexible connector, flexible connector can tense two pieces of clamping plates
So that its offer spring force in the same plane.
In the present invention, reinforcing bar is placed in the intersection of two pieces of clamping plates, during being clamped to reinforcing bar,
Reinforcing bar simultaneously squeezes two pieces of clamping plates.For two pieces of clamping plates after stress, one end transfers the force to guide sleeve pair
Spring is compressed, and the other end transfers the force to flexible connector, the both ends of flexible connector by outside pulling force, into
And elastic stretching deformation occurs, the two pieces of one end of clamping plate far from hinged end will respectively be rotated towards bottom plate direction, and then two
Block clamping plate just will form v-shaped structure, and reinforcing bar will be limited between two pieces of clamping plates of v-shaped structure, make reinforcing bar can not
It is mobile, it is limited.
As optimization, along the hinge shaft axis direction, uniform intervals offer at least two and are parallel to each other on the clamping plate
Through-hole, perpendicular to the axis direction of the hinged shaft, the through-hole on two pieces of clamping plates is right respectively for the centerline direction of through-hole
Should be arranged, the flexible connector include with the consistent a plurality of flexible reinforcement of number of openings on clamping plate described in monolithic, every
Flexible reinforcement corresponds to one group of corresponding through-hole, and the both ends of flexible reinforcement respectively pass through the through-hole in its side and stretch out in
Outside the other end of through-hole, the both ends of flexible reinforcement, which have been respectively fixedly connected with, can be connected on the clamping plate to flexible reinforcement
The limiting section that is limited of retraction.The elasticity for being used for a long time rear flexible reinforcement will decline, and can pass through replacement elasticity in this way
The mode of lacing wire, it is ensured that there are enough elastic forces to keep two pieces of clamping plates when unused in one plane, convenient for steel
Muscle is clamped.
As optimization, the cross-sectional shape of the guide sleeve be it is rectangular-shaped, the opposite side side of two guide sleeves is
It is arranged in parallel.The side of the guide sleeve of rectangular-shaped exterior cross-section is capable of providing enough mounting surfaces and facilitates setting hinged shaft and clamping plate
It is articulated and connected.
As optimization, the limiting section is integrally in strip, and the length of the limiting section is greater than the diameter of the through-hole, institute
The section maximum width for stating limiting section is less than the diameter of the through-hole, and the flexible reinforcement is fixedly connected on the limiting section along it
The middle position of length direction.After the flexibility decrease of flexible reinforcement, flexible reinforcement is pullled outward, is the axis direction of limiting section
After parallel with the centerline direction of through-hole, limiting section can pass through through-hole, make to replace more convenient.
In conclusion the utility model has the beneficial effects that: the utility model structure is simple, easy to use, Neng Gou
The position of reinforcing bar is limited during to reinforcing bar clamping, effectively ensures the thickness of concrete cover.
