The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. Embodiments of the utility model and features of the embodiments may be combined with each other without conflict. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

See fig. 1 to 5:

the utility model provides a fixer for construction steel bar, comprising: a support cylinder 10 vertically installed on the form C. The top of the supporting cylinder 10 is provided with four openings 11, and the four openings 11 are arranged at equal intervals along the circumferential direction of the supporting cylinder 10, so that the four openings 11 can be opposite to each other and form a cross-shaped supporting channel. The cross support channel is clamped with the intersection of the transverse steel bar B and the vertical steel bar A on the template C.

The bottom of the notch 11 is in an arc shape, and the arc can increase the contact area between the supporting cylinder 10 and the outer surface of the transverse steel bar B or the vertical steel bar A, so that the clamping connection is more stable.

The distance from the bottom of the gap 11 to the centering nail 14 is greater than the diameter of the transverse reinforcing steel bar B or the vertical reinforcing steel bar A. So that a certain distance can be generated between the reinforcing mesh woven by the transverse reinforcing steel bars B and the vertical reinforcing steel bars A and the template C.

Through such setting for support section of thick bamboo 10 is at the bottom formation support of the reinforcing bar net of interweaving by horizontal reinforcing bar B and vertical reinforcing bar A, and make the reinforcing bar net have certain interval with template C's upper surface, thereby make no longer need to add the gasket for the reinforcing bar net manual work when pouring concrete, labour saving and time saving. Meanwhile, as the supporting cylinder 10 belongs to a standard component, the whole reinforcing mesh supported by the supporting cylinder 10 is positioned on the same horizontal plane and cannot deform, so that the quality of a final pouring finished product is improved.

In addition, the cross type support channel on the support cylinder 10 can be used for clamping and fixing the intersection point of the transverse reinforcing steel bar B and the vertical reinforcing steel bar A, so that the laying arrangement of the transverse reinforcing steel bar B and the vertical reinforcing steel bar A can be combed before binding, and the engineering efficiency is improved.

A connecting pin 12 is provided at the bottom of the support cylinder 10. The supporting cylinder 10 is a regular quadrangular prism, and the bottom end of the side edge of the regular quadrangular prism is provided with a centering nail 14; the centering pin 14 is located on the center line of the side of the regular quadrangular prism.

Through such setting, to the engineering that the construction requirement is higher, when in actual use, constructor draws the circuit that horizontal reinforcing bar B and vertical reinforcing bar A laid on template C in advance, uses the circuit to replace the reinforcing bar to draw out the profile of reinforcing bar net in advance promptly. The cross junction of the line represents the junction where the transverse reinforcement B and the vertical reinforcement a meet when laid.

The supporting cylinder 10 is nailed at the cross junction of the drawn line of the template C through the connecting nails 12. In order to make the nail position more accurate, when the nail supports the section of thick bamboo 10, will support the line coincidence of the line of the cross line of the intersection department of nail 14 and circuit in the bottom of section of thick bamboo 10 to can guarantee that the cross type support channel on the section of thick bamboo 10 can be when horizontal reinforcing bar B and vertical reinforcing bar A lay with it perfect coincidence.

All the supporting cylinders 10 are nailed, and then the transverse steel bars B and the vertical steel bars A are sequentially clamped into the cross-shaped supporting channels of the supporting cylinders 10, so that the supporting cylinders 10 can fix the transverse steel bars B and the vertical steel bars A. And in the later stage, the transverse steel bars B and the vertical steel bars A can be bound or directly welded by electric welding.

For the engineering with low construction requirements, after the transverse steel bars B and the vertical steel bars A are bound, the supporting cylinder 10 is clamped at the intersection of the transverse steel bars B and the vertical steel bars A, and then the supporting cylinder 10 is nailed on the template C. Therefore, the steel bar net can be integrally lifted, the steel bar net can be positioned at the middle position of concrete during pouring, the condition that the poured steel bars are exposed is avoided, and the engineering quality is improved. In addition, the reinforcing mesh can resist the impact force of concrete pouring and cannot generate displacement due to the fixation of the support cylinder 10.

The support cylinder 10 is provided with slurry leakage holes 13, at least two slurry leakage holes 13 are arranged on the support cylinder 10, and the surfaces of the support cylinder 10 are distributed at equal intervals. Through such arrangement, cement paste can fully enter the support cylinder 10 when the support cylinder 10 is used for concrete pouring, and the overall rigidity of the pouring structure is improved.

In order to make the fixing of the transverse reinforcement B and the vertical reinforcement a by the support cylinder 10 more stable, a pressing cylinder 20 is further provided to be used in cooperation therewith. Similarly, the bottom end of the pressing cylinder 20 is provided with four notches 22, and the notches 22 are opposite to each other to form a cross pressing channel. The cross-shaped cross pressing channel is clamped with the intersection point of the transverse steel bar B and the vertical steel bar A on the template C, and the clamping direction is from top to bottom, and the pressing cylinder 20 is also vertically arranged on the template C, so that the intersection point of the transverse steel bar B and the vertical steel bar A is pressed to the surface of the template C.

In order to achieve the pressing effect, the pressing cylinder 20 is provided as a regular quadrangular prism. The bottom end of the pressing cylinder 20 is provided with a pressing connection pin 23. When in actual use, after the joint of the connecting nail 23 and the intersection point of the transverse steel bar B and the vertical steel bar A is clamped, the connecting nail is nailed to the template C.

The height of the pressing cylinder 20 is the same as that of the supporting cylinder 10, and the top of the notch 22 is flush with the top of the reinforcing steel bar positioned at the upper layer in the notch 11. Through this setting for each intersection of the reinforcing bar net that is woven by horizontal reinforcing bar B and vertical reinforcing bar A is in same horizontal plane, the condition of different height, deformation can not appear.

The pressing cylinders 20 and the supporting cylinders 10 are alternately distributed on the form C, so that the functions of supporting, pressing, re-supporting and re-pressing are formed at each intersection of the transverse reinforcing steel bars B and the vertical reinforcing steel bars a on the form C.
