Problems solved by technology

The waiting time of several hours between two casting processes is usually difficult to realize in the actual construction process
The reason is that the current concrete is dispatched by commercial concrete companies, and commercial concrete companies usually need to supply multiple construction projects at the same time, and cannot bear the time cost of waiting for several hours for dispatching vehicles

Embodiment 1

[0045] See attached Figure 1-3 , 5-7, 10-14, the present embodiment provides a concrete interception device, including a support body 1 and an interception unit; the support body 1 is a rigid vertical rod structure, which is used to provide support to fix the interception device on The template frame 17 includes an edge vertical rod 101 and a central vertical rod 102. There are at least two edge vertical rods 101, which are fixedly installed close to the vertical side wall of the template frame 17. The central vertical rod 102 is vertically arranged on Between the vertical bars 101 at the two edges. The top of the edge vertical bar 101 is provided with an L-shaped ear 103 extending outward to the outer wall of the formwork, the outer plate of the ear 103 extends downward parallel to the edge vertical bar 101, and the outer plate is set At least one through hole 104, the through hole 104 is a nail hole or an internal thread hole; the bottom of the edge vertical bar 101 is pro...

Embodiment 2

[0056] See attached Figure 4-6 , 8-14, the difference from Embodiment 1 is that: the vertical bars constituting the support 1 include two edge vertical bars 101 and at least one central vertical bar 102; the central vertical bar 102 can be against the beam hoop ribs; the bottom of the central vertical bar 102 is also provided with positioning nails 105 .

[0057] The invention provides a method for using a concrete intercepting device, comprising the following steps:

[0058] Step S1. Install interception device:

[0059] Step S1-1. Fixing the vertical bars: vertically set the two edge vertical bars 101 against the side walls of the formwork in the formwork frame 17, and vertically set the central vertical bar 101 against the beam stirrup 18 in the middle of the formwork frame 17 Nail the positioning nails at the bottom of the edge vertical bar 101 and the central vertical bar (102) into the bottom template, and fix the ears 103 of the edge vertical bar 101 to the outer sid...

Abstract

The invention relates to a concrete intercepting device and a using method thereof. The concrete intercepting device comprises a supporting body and intercepting units. The supporting body is of a rigid vertical rod structure so that the intercepting device can be fixed in a formwork frame of a cross beam. Vertical rods comprise at least two edge vertical rods and / or a plurality of central vertical rods, and the edge vertical rods can be tightly attached to the vertical side wall of the formwork frame to be fixedly installed; the intercepting units comprise plane intercepting parts, column air bags and ring air bags, and the column air bags and the ring air bags are correspondingly positioned on two sides of the plane intercepting parts; a column cavity can be placed into an annular inner cavity or taken out of the annular inner cavity through a slit-shaped opening when not inflated, and when the two air bags are both inflated, the column air bags can be clamped and fixed in the annular inner cavity; a gap is formed between every two adjacent sub-ring air bags; a plurality of annular bending parts are arranged on the column air bags matched with the sub-ring air bags, and an annular gap is formed in each bending part; and the annular gaps are used for accommodating beam main reinforcements and hooping the beam main reinforcements after the column air bags are inflated.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a concrete intercepting device and an application method thereof. Background technique [0002] Strong-column-weak-beam structure is a widely used structural form in the field of architecture. When casting concrete for this structure, it is necessary to use high and low grades of concrete to cast columns and beams successively. During the casting process, it is necessary to intercept the high and low grade concrete to prevent the channeling of different grade concrete, which will lead to waste of high grade concrete and cracks in the cast structure, which will affect the structural strength and other issues. [0003] Existing concrete interception structures include several types such as wire mesh, grille and air bag. Wire mesh interception is the most widely used interception method in the actual construction process. It refers to binding steel wire mesh directly on the...
