Description
Technical Field
The utility model relates to a concrete placement interception instrument technical field, in particular to an interception piece for pouring beam column node concrete.
Background
At present, beam column node concrete placement does not have special instrument to go the interception, and constructor or not block, in wanting to flow into the roof beam by the concrete, or all with shutoff such as flitch, template, braided bag, reinforcing bar, the interception effect is extremely poor, also not easy the removal, and the pick chisel degree of difficulty is very big, and perhaps extravagant reinforcing bar is serious, can't guarantee that the interception effect satisfies and establishes the design code requirement, seriously influences the structural quality safety, and the risk is great.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a technical problem provide an interception piece for pouring beam column node concrete, the poor problem of interception effect when solving current beam column node concrete placement.
In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the utility model provides an interception piece for pouring beam column node concrete, includes first reinforcing bar, zinc-plated iron wire and wire net, and first reinforcing bar arranges along vertical direction, and the interval is provided with zinc-plated iron wire uniformly on the first reinforcing bar, and zinc-plated iron wire arranges along the horizontal direction, the wire net is pricked the silk through zinc-plating and is fixed on zinc-plated iron wire, the lower extreme of wire net flushes with the lower extreme of first reinforcing bar.
The technical principle of the technical scheme is as follows: when the beam column node is poured on site, firstly, the beam reinforcement framework is installed, and the upper openings of the stirrups at the rest planned interception positions are not bound; then, inserting the interception piece into the beam until reaching the bottom die by inclining 45 degrees (the iron wire is parallel to the longitudinal beam rib) and propping against the bottom of the stirrup, and then rotating the interception piece by 90 degrees to enable a net surface formed by the galvanized iron wire and the steel wire gauze to face one side of the concrete to be intercepted; inserting the other intercepting parts in sequence according to the step until the whole beam section is sealed; and finally, the stirrups which are not bound at the top are reinstalled and bound firmly, and one of the stirrups is fixed by abutting against the outer side of the interception piece, so that the interception piece is prevented from moving when concrete is poured. And (5) after the installation is finished, checking the sealing condition, wherein a gap exists in the local part, and the steel wire mesh can be used for plugging again. After the concrete is poured, knocking the intercepting piece after the initial setting of the concrete or when the concrete of the beam plate begins to be poured, rotating the intercepting piece for 90 degrees after the intercepting piece is loosened, pulling out the intercepting piece, and recycling the intercepting piece again.
The beneficial effect that this scheme produced is: in the prior art, concrete pouring at the beam-column node is not provided with a special tool for intercepting, and constructors either do not block the concrete and let the concrete flow into the beam or use battens, templates, woven bags, reinforcing steel bars and the like for plugging, so that the intercepting effect is extremely poor, the concrete is not easy to remove, the difficulty of chiseling is extremely high, or the waste of the reinforcing steel bars is serious, the intercepting effect cannot be ensured to meet the requirement of design specifications, the structural quality safety is seriously influenced, and the risk is high; and the interception piece through reinforcing bar and wire net preparation in this application scheme, simple manufacture, the cost is extremely low, convenient to use, the interception is effectual, and the quality is firm, can have enough to meet the need the use many times, can guarantee beam column node concrete placement quality, satisfies the designing requirement. The method is suitable for interception of concrete with different strengths of all beam-column nodes or interception during segmental pouring.
Further, a second reinforcing steel bar arranged in the horizontal direction is fixed at the upper end of the first reinforcing steel bar. The second reinforcing bar plays the effect of handle, conveniently removes this interception piece.
Furthermore, the first steel bar has the size of phi 12 mm-phi 20mm and the length of 800 mm-2000 mm.
Furthermore, the distance between two adjacent galvanized iron wires is 30-40 mm.
Furthermore, the galvanized iron wire is No. 8 galvanized iron wire, and the length of the galvanized iron wire is 15-18 mm.
Furthermore, the size of the second steel bar is phi 12-14mm, and the length of the second steel bar is 50-70 mm.
Further, the steel wire mesh is a 20-mesh steel wire mesh.
Further, the galvanized binding wire is No. 22 galvanized binding wire.

Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: second reinforcing bar 1, first reinforcing bar 2, wire net 3, zinc-plated iron wire 4.
The embodiment is basically as shown in the attached figures 1-2: the utility model provides an interception piece for pouring beam column node concrete, includes first reinforcing bar 2, second reinforcing bar 1, zinc-plated iron wire 4 and wire net 3.
As shown in fig. 1, the first reinforcing bars 2 are arranged in a vertical direction, and the first reinforcing bars 2 have a size of phi 15mm and a length of 1000 mm. The welding of the upper end of first reinforcing bar 2 has second reinforcing bar 1, and second reinforcing bar 1 arranges along the horizontal direction, and the size of second reinforcing bar 1 is phi 13mm, and length is 50 mm. The second reinforcing bar 1 plays the effect of handle, conveniently removes this interception piece.
As shown in fig. 1, the galvanized iron wires 4 are uniformly welded on the first steel bar 2 at intervals, the galvanized iron wires 4 are arranged along the horizontal direction, the distance between every two adjacent galvanized iron wires 4 is 30mm, the galvanized iron wires 4 are No. 8 galvanized iron wires, and the length of the galvanized iron wires 4 is 15 mm.
As shown in fig. 1, the steel wire mesh 3 is a 20-mesh steel wire mesh 3, the steel wire mesh 3 is fixed on the galvanized iron wire 4 through galvanized binding wires, and the lower end of the steel wire mesh 3 is flush with the lower end of the first steel bar 2. The steel wire mesh 3 and the first steel bar 2 are coaxially arranged. The galvanized binding wire used in the present embodiment is a No. 22 galvanized binding wire.
