Description

High-low grade concrete blocking device for beam-column joints

Technical Field

The utility model relates to a high low grade concrete of beam column node blocks and separates device belongs to the construction field.

Background

At present, high-rise buildings are more and more, the condition that the concrete labels between beam plates and columns are different by more than two grades generally exists, according to the standard requirement, the position of 500mm at the node of a beam column needs to be separated by high-label concrete and low-label concrete, the concrete pouring at the node position of the beam column is generally simultaneous pouring, the separation generally adopts a quick-easy closing net, if the quick-easy closing net is not positioned in the installation and fixation in the construction process, the high-label concrete flows into the low-label concrete area, the high-label concrete is wasted, the low-label concrete flows into the high-label concrete area, particularly the core position of the node of the beam column, the safety of the building structure is seriously influenced, and quality safety accidents are easily caused.

The related prior art:

1. the Chinese patent application CN106639320A discloses a method for pouring concrete with different labels on beam-column joints, which is an integral device manufactured according to actual on-site dimensions.

2. Chinese utility model patent CN206769387U discloses a different-label concrete intercepting device.

3. Chinese utility model patent CN207727761U discloses a separator of different grade specifications concrete of beam column node, and this patent adopts the stagnant water screw rod to consolidate the wire net and handles, with the wire net as for above the stagnant water screw rod. However, the water stop screw rod interval of this patent can not be too big, and too big concrete just can probably follow high-grade district flow direction low-grade district, and the water stop screw rod is more, and it is not more convenient to consolidate yet, and the slant muscle is fixed through leading to long muscle from top to bottom, and it is also not very good operation to fix, need advance with leading to long muscle from top to bottom and ligature or spot welding solid yet, also increases the installation degree of difficulty, and water stop screw rod and slant muscle can not take out reuse moreover, and the material waste is great.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a beam column node height grade concrete blocks and separates device, this concrete blocks and separates device simple manufacture, but reuse, the installation is fixed convenient, and the position is accurate, practices thrift simultaneously and separates reinforced material and manual work, blocks to separate the effect splendid, and the quality is guaranteed to the loss of reducible high grade concrete.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is:

a high-low grade concrete blocking device for beam-column nodes is installed at the beam-column nodes, beam stirrups, beam bottom reinforcements and tie reinforcements are arranged in pouring areas of beams, and column reinforcements are arranged in pouring areas of columns; the structure is characterized in that a closing-up net which is vertically arranged is arranged at the node of the beam column, a low-grade concrete area is arranged on one side of the closing-up net, which faces a pouring area of the beam, a high-grade concrete area is arranged on one side of the closing-up net, which faces the pouring area of the column, a concrete blocking and separating unit which is vertically arranged is arranged between the closing-up net and the beam stirrups, and the bottom end of the concrete blocking and separating unit abuts against a bottom template of the beam.

Therefore, the concrete blocking unit is limited and fixed through the beam stirrups and the closing net, and the high-grade concrete can be prevented from flowing into the low-grade concrete.

According to the utility model discloses an embodiment, can also be right the utility model discloses do further optimization, following for optimizing the technical scheme who forms afterwards:

in order to further improve the reliability of the intercepting device, a draw hook is arranged between the low-grade concrete area and the high-grade concrete area, and the draw hook and the beam stirrups are used as the back edges of the concrete intercepting and separating units together.

In order to facilitate the loading or unloading of the concrete interception unit, the concrete interception unit comprises a pull ring positioned at the top and a plurality of interception parting strips arranged at intervals.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses it is stupefied as the back of the body that fine stirrup and drag hook in utilizing the structure roof beam combine the net that closes up soon easily, have carried out fine blocking to the high low grade concrete of beam column node department and have separated, and this device simple manufacture, but reuse, material saving and manual work block separate the effect splendid, and the quality is guaranteed, can reduce the high grade concrete.

Compared with CN106639320A, the utility model discloses an intercepting device is more simple and convenient than its operation installation and the turnover of getting profitable, the utility model discloses an intercepting device relies on the stirrup and the lacing wire of structure roof beam itself as the stupefied atress of the back of the body, need not consider in addition the reinforcement measure.

Compared with CN206769387U, the utility model discloses all need simple and convenient in preparation and installation, interception material operation requirement does not have its height yet, need not adopt the steel sheet, only need adopt more economic fast easy binding off net and base device combine can, this device is more convenient in reuse.

Compared with CN207727761U, the utility model discloses can process in the reinforcing bar workshop according to design drawing size, directly place in the installation on one side at the stirrup and the drawknot muscle of structure roof beam can, the reunion blocks with the net that easily closes up soon and separates, treats that the height concrete has poured the back, just can propose immediately, next one deck reuse.
