Description

A kind of Steel bar rack
Technical field:
The utility model relates to building fields, are specifically designed a kind of Steel bar rack.
Background technique:
The high-rise of present reinforced concrete structure, mostly uses greatly shear wall structure, and this shear wall structure is big Mostly use double layer bar.According to structural mechanics, position of the steel mesh in shear wall structure is to have certain requirements, steel mesh Structure is too big at a distance from concrete surface or the too small intensity that can all influence structure sheaf and service life.
Existing Steel bar rack is mostly to carry out bending machining to an iron, is then welded on the iron after processing The lower surface of reinforcing bar, double layer bar are supported by several irons.
The Steel bar rack formed in this way is too small to the bearing area of reinforcing bar, is easy to happen change during casting concrete Shape causes the distance between double layer bar to be unable to get preferable control, influences whether the stability of double steel bar web frame.
Utility model content:
The purpose of the utility model is to provide a kind of Steel bar racks, can carry out to the distance between double layer bar preferable Control, to improve the stability of double steel bar web frame.
The technical purpose of the utility model has the technical scheme that
A kind of Steel bar rack, including pedestal and fixed plate, the fixed plate include to be arranged from top to bottom for bilayer The first support portion and the second support portion that steel mesh is supported, first support portion are opened up far from one end of the second support portion There is the locating slot taken and put for top bars, second support portion has the location hole passed through for lower layer's reinforcing bar.
By using above-mentioned technical proposal, the top layer steel mesh in double layer bar is taken after welding finishes is placed on first In the locating slot of support portion, bottom layer of the reinforcing steel is inserted into positioning hole, re-lays the reinforcing bar perpendicular to insertion reinforcing bar and positions in insertion The reinforcement welding in hole forms lower layer's steel mesh, by controlling the distance between locating slot and location hole, can control two layers of steel The distance between muscle net, make the distance between double steel bar layer relatively rationally, can be obtained after completing concrete casting compared with Good bond strength, to guarantee that preferable structural strength can be had by shearing layer.
Run through on second support portion as a further improvement of the utility model, and offers and location hole radial communication Reinforcing bar introduction channel.
By using above-mentioned technical proposal, reinforcing bar can be by reinforcing bar introduction channel laterally imported positioning hole, and being not necessarily to will Reinforcing bar is inserted into after being aligned with location hole, facilitates the importing of reinforcing bar, improves the efficiency that worker is laid with bottom layer of the reinforcing steel net.
The locating slot is circular groove as a further improvement of the utility model, and the is provided in locating slot One non-slip mat.
It enables to reinforcing bar to take by the way that the groove being arc-shaped is arranged in locating slot by using above-mentioned technical proposal and puts The center of locating slot is dropped down onto after in locating slot, can top rebars be played with preferably supporting role, while first is anti- Skidding increases the maximum static friction force that top rebars item jumps, and reduces the possibility that axial jump occurs for reinforcing bar, increases The stability of top mat.
The location hole is anti-towards being provided with second on the hole wall of pedestal side as a further improvement of the utility model, Skidding.
By using above-mentioned technical proposal, by the design of the second non-slip mat, bottom reinforcement bars are installed into after locating slot, the Two non-slip mats increase the maximum static friction force that bottom steel rib jumps, and prevent bottom layer of the reinforcing steel from sliding axially, and increase The stability of bottom layer of the reinforcing steel net is added.
First support portion extends shape towards two sides in the slot bottom of locating slot as a further improvement of the utility model, At structural strengthening edge.
By using above-mentioned technical proposal, structural strengthening is single from small reduction along the bearing area increased to top rebars Plane product can be reduced by pressure because of top mat overweight the occurrence of causing Steel bar rack to deform.
Several structural strengthenings are provided between second support portion and bottom plate as a further improvement of the utility model, Muscle.
By using above-mentioned technical proposal, enhance the ability that Steel bar rack bears axial force, will not because in casting process, Axial force crosses ambassador's Steel bar rack and deforms, and causes structural strength to be affected to influence the service life of structure sheaf.
The structural bead is uniformly distributed in the two sides of fixed plate, and phase as a further improvement of the utility model, It is mutually symmetrical.
Reinforcing rib is enhanced by making structural bead be distributed in the two sides of fixed plate by using above-mentioned technical proposal For the structural strengthening effect of Steel bar rack, keep the stress of Steel bar rack two sides more uniform.
Deformable rubber pad is provided on the lower end surface of the pedestal as a further improvement of the utility model,.
By using above-mentioned technical proposal, when pedestal is mounted on concrete layer, the blinding on concrete layer is easy Skew occurs when pedestal is installed, by being provided with deformable rubber pad, deformable rubber pad can generate change when being pressed onto blinding Shape, so that skew occurs after avoiding pedestal from installing, to guarantee the accuracy for being laid with double layer bar.
In conclusion the utility model has the following beneficial effects:
Top layer steel mesh in double layer bar is taken after welding finishes to be placed in the locating slot of the first support portion, bottom Reinforcing bar is laterally sent into positioning hole by reinforcing bar guide channel, re-lays vertical reinforcing bar and in the reinforcement welding shape of insertion location hole At lower layer's steel mesh, by the way that the distance between two layers of steel mesh can be controlled to the control of the distance between locating slot and location hole, So that the distance between double steel bar layer relatively rationally, preferable bond strength can be obtained after completing concrete casting, from And preferable structural strength can be had by guaranteeing shearing layer.
