Description
Technical Field
The utility model relates to a civil engineering equipment technical field, specific is a different intensity level concrete placement plugging device of beam column node.
Background
Along with the increase of urban land price, the density of house buildings is gradually improved, and high-rise buildings are more and more common. However, under the condition of the ultra-high width ratio far away from the safety coefficient, the absolute stability of the high-rise building is ensured, and the ' strong column, weak beam, strong shear, weak bending ', strong node and strong anchoring ' are particularly important.
As is well known, the strength grades of the adopted concrete of the 'strong column' and the 'weak beam' are different, and according to the plugging effect of the previous engineering, the joint of the concrete with different strength grades has poor living impression and is easy to generate shrinkage cracks, so that the plugging measure of the beam-column joint is very critical.
The concrete blocking method of the prior art at the beam-column node is to use a mesh with a certain aperture to establish a partition surface at the beam-column node, for example, a lead net or a quick-easy-closing net is used to establish a partition between two kinds of concrete at the beam-column node. Use fast easy binding off net as the example, fast easy binding off net is fixed on roof beam framework of steel reinforcement, and the framework of steel reinforcement of roof beam includes main muscle in four corners, waist muscle and stirrup, and in the work progress, will at first close off the net soon and make with roof beam cross-section matched with squarely, offer the notch at two sides of square fast easy binding off net to the position of cooperation main muscle. In addition, when concrete placement is carried out to the beam column, pour post concrete earlier, back pouring beam concrete, the rigidity of the net self that easily closes up is very poor soon, and the post concrete of pouring can produce lateral pressure to the net that easily closes up soon, makes easily that the net warp or drops from the roof beam steel bar skeleton of easily closing up.
As shown in fig. 1, in a part of the construction process, in order to solve the problem, the fast and easy closing-up net and the beam steel reinforcement framework are arranged at a certain angle to reduce the lateral pressure of the column concrete, but in the construction process, the fast and easy closing-up net needs to stride across a plurality of stirrups on the beam steel reinforcement framework, so that the difficulty is increased for the installation of the fast and easy closing-up net, and the construction cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a different intensity level concrete placement plugging device of beam column node especially is fit for the concrete shutoff at the beam column node of "strong post weak beam", can effectively solve the problem that the net intensity is not enough that easily closes up soon, has simple structure, the simple operation, advantage that the processing cost is low, very big reduction the construction degree of difficulty.
The technical scheme of the utility model is that:
the utility model provides a different intensity grade concrete placement plugging device of beam column node, includes: fast easy binding off net and steel bar brace, be equipped with n on the fast easy binding off net and say V type net bone that is parallel to each other, the steel bar brace includes that n says erectly to prop, is parallel to each other between erectly propping, and the interval of erectly propping matches with the interval of the online adjacent V type net bone of fast easy binding off, the one end of erectly propping is passed through the stull and is fixed continuous, and n is more than or equal to 2's integer.
The V-shaped net rib is a straight line long groove with a V-shaped structure on the quick and easy closing net and is a main source of the strength of the quick and easy closing net.
The utility model discloses when using, will fast easily close up net cut out into with roof beam cross-section matched with size, will fast easily close up the net according to the vertical state of V type net bone and fixed together with roof beam steel reinforcement skeleton. One side of keeping away from the post at the net that easily closes up sets up the reinforcing bar and props, and one side that the reinforcing bar propped offsets with the stirrup, and the opposite side that the reinforcing bar propped cooperatees with the V type net bone of the net that easily closes up soon.
The vertical support length of the steel bar support is matched with the height of the cross section of the beam, the distance and the number of the vertical supports are matched with the V-shaped net rib of the fast and easy closing-up net, and the steel bar support can be made temporarily by using deformed steel bars according to the fast and easy closing-up net in the same batch.
When pouring the post concrete, the lateral pressure is exerted for the fast easy binding off net to the post concrete, and fast easy binding off net itself is difficult to resist this pressure, sets up the reinforcing bar through the one side at the fast easy binding off net and props, props through the reinforcing bar and supports fast easy binding off net, and the reinforcing bar props to be spacing by the stirrup to the support that can be stable fast easy binding off net makes fast easy binding off net realize the shutoff function.
And a lifting handle is arranged on one side of the cross brace, which is far away from the vertical brace.
Specifically, the handle is arc-shaped.
After the beam column concrete is poured, the reinforcing steel bar support is pulled out before the concrete is finally set, the concrete can be repeatedly used when being plugged next time, and the lifting handle is convenient for the reinforcing steel bar support to be taken out.
The utility model has the advantages and positive effects be: due to the adoption of the technical scheme, the plugging device can be used for plugging the joints of the beam column conveniently and quickly, and has the characteristics of low cost and convenience in operation.

Detailed Description
As shown in fig. 2-4, the utility model discloses:
the utility model provides a different intensity grade concrete placement plugging device of beam column node, includes: fast easy binding off net 1 and reinforcing bar prop 2, be equipped with n on the fast easy binding off net and say V type net bone 11 that is parallel to each other, the reinforcing bar props including n way erects to prop 21, and is parallel to each other between erectting, and the interval of erectting props matches with the interval of fast easy binding off net adjacent V type net bone 11, the one end of erectting props is passed through stull 22 and is fixed continuous, and n is more than or equal to 2's integer.
And one side of the cross brace, which is far away from the vertical brace, is provided with a circular arc-shaped handle 23.
The working process of the example is as follows:
the utility model discloses when using, will fast easy binding off net 1 tailor into with roof beam cross-section matched with size, adopt the toothless saw to cut fast easy binding off net, guarantee that the cutting is in the same direction as straight level and smooth. The size of the fast and easy closing net is reduced by 5mm compared with the size of the cross section of the beam, so that the damage caused in the beam falling process is prevented. And welding a steel bar support by adopting HRB400 phi 12 steel bars, and welding the steel bar support according to the position of the beam steel bar and the position of the V-shaped net rib.
After the beam reinforcement is bound, the fast and easy binding net is bound and fixed on the stirrup 3 of the beam reinforcement framework. The fast and easy binding net needs to extend to the two sides and the bottom of the stirrup, and the position of the fast and easy binding net corresponding to the beam main rib 4 and the waist rib 5 is provided with a corresponding open slot 12 which penetrates through the steel bar to be bound to a position 5mm away from the edge of the template.
After the fast and easy closing net is bound to the stirrups, the reinforcing bar supports are inserted between the closing net and the stirrups and fall into the beam together.
After the beam column concrete is poured, the reinforcing steel bar support is pulled out before the concrete is finally set, and the concrete can be repeatedly used in the next plugging process.
