Description

Technical Field

[0001] The utility model specifically relates to a high and low grade concrete intercepting device suitable for standard layer beam-column nodes, belonging to the technical field of concrete construction auxiliary devices. Background Art

[0002] With the increasing scarcity of land resources, high-rise and even super-high-rise buildings are emerging in an endless stream. With the increase in building height, the concrete grade of columns and walls in concrete structures will inevitably increase. There will be a large number of column beams and wall beams whose concrete strength grades differ by more than two grades. If no method is found to intercept them, high and low grades will be mixed, which will cause serious structural safety hazards. In the process of pouring concrete, wire mesh is often used to intercept in the beams around the columns. However, if only wire mesh is used for interception, the wire mesh can be easily expanded and lose its effectiveness during the actual pouring process, resulting in a large amount of high-grade concrete flowing into the beams, and the columns are difficult to fill. When the concrete is poured to the bottom of the structural slab, the high-grade concrete will flow into the slab surface. After forming, the bottom of the slab will have irregular color difference, which looks very poor. This requires an interception device, but most of the existing interception devices are disposable and not easy to reuse.

[0003] As shown in the announcement number: CN218952827U, a high- and low-grade concrete intercepting device for beam-column joints includes multiple concrete upper steel bars, concrete lower steel bars and concrete structural steel bars of concrete beams, and also includes advanced concrete stirrups sleeved on the outside of the concrete upper steel bars, concrete lower steel bars and concrete structural steel bars of concrete beams, the outside of the advanced concrete stirrups is sleeved with multiple movable sleeves, and the outer wall of one side of the movable sleeve is welded with a main reinforcement perforated plate, the inner wall of the main reinforcement perforated plate is matched with the concrete upper steel bars, concrete lower steel bars and concrete structural steel bars of concrete beams, all device materials of the utility model can be quickly obtained from the processing plant or the construction site, easy to process and convenient to construct, the device can effectively solve the problem of different grade concretes in the beam-column joints, the advanced concrete stirrups of the intercepting device can be processed in advance according to the position to be intercepted, suitable for different cross-sectional sizes, and strong applicability.

[0004] However, the high-low grade concrete interception device for the beam-column joint disclosed above is not convenient for reuse and installation. Utility Model Content

[0009] Furthermore, in order to facilitate the adjustment of the position of the connecting rod, a connecting rod is fixedly mounted on the sliding block, and the connecting rod is plugged into the movable hole. When the sliding block moves, the connecting rod moves.

[0010] Furthermore, in order to facilitate the rotation of the anti-sliding block, a fixing rod is installed on the connecting rod, and a fixing plate is fixedly installed on the fixing rod. The fixing plate moves by moving the connecting rod, and the anti-sliding blocks arranged in an array are installed on the fixing plate.

[0011] Furthermore, in order to facilitate the inflation and deflation of the interception airbag, the interception airbag is provided with an inflation and deflation nozzle, a cover plate is clamped on the nozzle, and the interception airbag is made of composite PVC composite mesh cloth.

[0012] Furthermore, in order to facilitate the clamping with the upper concrete steel bars and the lower concrete steel bars, a clamping hole is opened on the mounting plate and located between the intercepting airbags.

[0013] Furthermore, in order to facilitate the removal of the mounting plate, a handle is installed on the mounting plate, and some of the concrete stirrups are installed with side steel bars.

[0014] The technical effects and advantages of the utility model are as follows: the fixing plate can be conveniently fixed to the upper steel bars of concrete and the lower steel bars of concrete through the fixing assembly, so that the intercepting airbag can be conveniently placed in a suitable position, thereby facilitating the interception of concrete of different grades, and after the interception is completed, it can be removed for reuse.
