Description

The positioning fixture of reinforcing bar in the reinforced concrete structure

The utility model relates to the positioning fixture between the steel bar stress and template in the reinforced concrete work.

At present, the structure overwhelming majority that building, hydraulic engineering construction adopted is a reinforced concrete structure.When reinforced concrete work is constructed; for the fixing position of steel bar stress; guarantee the thickness of concrete cover of cage of reinforcement periphery; adopted following two kinds of methods during construction: a kind of is to fill up discharge water silt particle slurry cushion block or concrete pad between steel bar stress and template, and a kind of is the welded reinforcement frame.Yet, though first method is simple, but when practice of construction, cement mortar cushion block or concrete pad usually cannot stand the construction vibration, easily squeeze broken or displacement, make the precision of reinforced concrete structure protective layer thickness be difficult to be guaranteed, thereby influence workmanship, even can produce and reveal the consequence that muscle etc. influences structural life-time; Though second method is reliable, the expense of taking a lot of work material has increased engineering cost and difficulty of construction.

The purpose of this utility model provides a kind of novel reinforcing bar positioning fixture, and it can guarantee that the location of steel bar stress is solid and reliable in the reinforced concrete structure, and the precision of reinforced concrete structure protective layer thickness is guaranteed, and construction is simple, convenient.

In order to achieve the above object; the utility model is realized by following scheme; it is the clamp ring that also reinforcing bar can be embedded by opening by the band opening; clamp ring is provided with the roker of mechanical properties such as meeting structural strength, rigidity and thickness of concrete cover requirement outward; the roker top is provided with outer shroud, and outer shroud is provided with to be stood the construction vibration and push the support composition of firm support on template still.When the assembling reinforcement skeleton; on reinforcing bar, locate to put anchor clamps of the present utility model mutually across a certain distance; assemble template then, the location of steel bar stress is solid and reliable in the reinforced concrete structure that can guarantee to build, and the precision of reinforced concrete structure protective layer thickness also is guaranteed.

The utility model has the advantages that:

1. the utility model is simple in structure, and dependable performance can be produced in batches in plastics plant.

2. use anchor clamps of the present utility model not only can reduce the mass defect that human factor causes; and it is very convenient to construct; as long as on reinforcing bar, locate to put anchor clamps of the present utility model mutually across a certain distance; assemble template then, just can guarantee that the construction precision and the steel bar stress of the thickness of concrete cover of being built is not shifted.

3. the utility model is applied widely, not only roker can be designed to 50mm, 35mm, 25mm and 15mm etc. to meet the different thickness of concrete cover requirement of basis, beam, post, floor, cantilevered plate, seismic shear wall etc. to the total length that supports; And its shape also can be made width of cloth rib around clamp ring 360 degree, 180 degree, 90 degree, 45 degree etc. by the needs of above-mentioned different component type and different parts.In wall, plated construction, also can adopt two anchor clamps are used in pairs, be connected as a single entity with connecting rod, both can guarantee protective layer thickness, can guarantee the spacing of reinforced mesh in wall, plate thickness He Qiang, the plate again.

Embodiment 1

The utility model 5 is made up of clamp ring 1, roker 2, outer shroud 3, support 4.

Elder generation can form one group with some adjacent diameter as the reinforcing bar of 14mm and 16mm, the clamp ring 1 of the same specification of shared internal diameter according to the internal diameter of the clamp ring 1 of the definite band of the diameter opening of the steel bar stress of the used steel concrete of engineering construction.Then respectively by reinforced concrete foundation beam, post, floor, encorbelment or the need of different component type, purposes and rigidity such as wall are designed to be 360 degree, 180 degree, 90 degree, 45 degree with clamp ring 1 with clamp ring 1 outer roker 2 and meet the roker 2 of thickness of concrete cover 50mm, 35mm, 25mm and 15mm requirement; the top of roker 2 is provided with outer shroud 3, also is provided with on the outer shroud 3 can resist reinforcing bar and vibrated and push the support 4 that still positioning fixture 5 can be bearing on the template 13.

Embodiment 2

When being used for the utility model 5 on the reinforced concrete beam formed by the stirrup 7 in longitudinal stress reinforcing bar 6, beam or the post of beam or post or the post; earlier determine clamp ring 1 internal diameter according to the diameter of steel bar stress 6; thickness of concrete cover by beam or post is that 25mm requirement and stress performance require to make the roker 2 that is 360 degree with clamp ring 1 then, roker 2 outer support 4 composition the utility model 5 that are petal or waterwheel wheel shape that are provided with.As long as on four longitudinal stress reinforcing bars 6 of four jiaos of the bottom comer of beam and top corner part or post; the stirrup 7 of limit colligation beam or post; the limit by 3 meters between left and right apart from putting anchor clamps 5 of the present utility model; can guarantee the stressed position of longitudinal stress reinforcing bar 6 in template 13 of concrete of beam or post, also can guarantee the protective layer thickness of steel concrete.Roker 2 also can adopt 180 degree or 90 degree.

Embodiment 3: the utility model 5 is used for reinforced concrete floor or when encorbelmenting, floor or encorbelment in often be furnished with advocated muscle 8 and distribution reinforcement 9.Can determine clamp ring 1 internal diameter according to the diameter of the muscle 8 of being advocated in the plate earlier; be the mechanical property of 15mm requirement and one-way slabs, two-way slab then by thickness of concrete cover; outside clamp ring 1, make the roker 2 that is 180 degree, 90 degree or 45 degree with clamp ring 1, outside roker 2, be provided with outer shroud 3 and support 4.When the unidirectional floor bar skeleton of colligation; on the muscle 8 of being advocated, put the utility model 5 by 1-3 rice spacing; when the two-way floor bar skeleton of colligation; in the plate of lower floor, advocated on the muscle 8; put the utility model 5 by 1-3 rice spacing; when colligation cantilevered plate cage of reinforcement; because general be provided with fixedly in the end of steel concrete cantilevered plate steel bar stress 8 more; can guarantee the effective height of plate; but because factors such as reinforcing bar deadweight; when encorbelmenting greatly; reinforcing bar around the song distortion effective height of plate is reduced, when serious even can influence structural safety, therefore in plate, advocated on the muscle 8 by 1-3 rice spacing; put the utility model 5, the protective layer thickness of the cage of reinforcement that can guarantee to encorbelment.
