Abstract

The utility model provides a novel steel bar connecting system with multiple beams intersecting. The novel steel bar connecting system with the multiple beams intersecting comprises a reinforced concrete column and a plurality of reinforced concrete column frame joints where the multiple reinforced concrete beams intersect. A key steel plate is arranged at the positions of the reinforced concrete column frame joints. The area of the key steel plate is smaller than the sectional area of the reinforced concrete column. The key steel plate is horizontally arranged in the reinforced concrete column. Beam steel bars of each reinforced concrete beam which intersects with other reinforced concrete beams at the corresponding reinforced concrete column frame joints are welded to the key steel plate. A pouring hole is formed in the center of the key steel plate. According to the novel steel bar connecting system with the multiple beams intersecting, construction is convenient and formwork erection is easy; due to the fact that the key steel plate is small in size, the steel bars of the reinforced concrete column cannot be influenced, concrete pouring is also convenient, and the anti-seismic performance is good; the structure is simple, machining of complicated parts is avoided, use is convenient, and the manufacturing cost is low.

Description

The new reinforcing steel bar connected system that a kind of many beams are crossing

Technical field

The utility model relates to concrete construction frame construction technical field, especially relates to the crossing new reinforcing steel bar connected system of a kind of many beams.

Background technology

When available frame post intersects more than 4 beams, beam column reinforcing bar is intensive, and concrete is difficult to build, and general employing adds cap or strengthen column section, but all can affect building function.

Utility model content

The purpose of this utility model is to design the crossing new reinforcing steel bar connected system of a kind of novel many beams, addresses the above problem.

To achieve these goals, the technical solution adopted in the utility model is as follows:

The new reinforcing steel bar connected system that many beams are crossing, comprises reinforced concrete post and the crossing reinforced concrete frame node of a plurality of reinforced concrete beam, and described reinforced concrete frame node arranges core steel plate; The area of described core steel plate is less than the sectional area of described reinforced concrete post, and is horizontally placed in reinforced concrete post; Beam steel described in each intersecting at described reinforced concrete frame node place on reinforced concrete beam is welded on described core steel plate; Described core steel plate center has plug hole.

Described plug hole is boring or punching.

The diameter range of described plug hole is 200-500.

Be welded on described beam steel 1:6 on the described core steel plate setting of bending.

Described core steel plate is provided with post reinforced hole, and the post reinforcing bar on described reinforced concrete post is through described post reinforced hole.

Described a plurality of reinforced concrete beam refers to the described reinforced concrete beam that is greater than 4.

Proportion 0.4-0.8 between the area of described core steel plate and the sectional area of described reinforced concrete post.

Adopt this technology, easy construction, formwork is simple, and core steel plate is less than post, can not affect post reinforcing bar, in the middle of steel plate, opens circular hole, and concreting is also very convenient.

1. product invention: reinforced concrete frame node place beam steel anchors into post core space traditionally, when many beams intersect, generally adds cap, and the creationary introducing steel plate of this technology, is connected on steel bar welding on steel plate, makes node area greatly reduce reinforcing bar overlapping,

2. steel plate center drilling, ensures concrete building.

3. steel plate center drilling, technological requirement adopts boring or punching, ensures that tapping can not concentrate by stress;

4. reinforcing bar can bend by 1:6, ensures that reinforcing bar is too not intensive at Nodes, meets again beam and does not reduce depth of section;

5. when Bar Anchorage is not enough, steel plate strengthens, and the utmost point in particular cases, can hole and pass through on steel plate by post reinforcing bar, efficiently solves not increasing column cross-section size, ensures again joint structure;

6. adopt this technology, Seismic Behavior is fine.

The beneficial effects of the utility model can be summarized as follows:

1, the utility model easy construction, formwork is simple, and core steel plate is less than post, can not affect post reinforcing bar, and concreting is also very convenient, and shock resistance is good.

2, the utility model is simple in structure, without the processing of complex parts, easy to use, cheap for manufacturing cost.

The specific embodiment

Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

The crossing new reinforcing steel bar connected system of a kind of many beams as shown in Fig. 1 to 5, comprises reinforced concrete post 1 and the crossing reinforced concrete frame node of a plurality of reinforced concrete beam 2, and described reinforced concrete frame node arranges core steel plate 3; The area of described core steel plate 3 is less than the sectional area of described reinforced concrete post 1, and is horizontally placed in reinforced concrete post 1; Beam steel 4 described in each intersecting at described reinforced concrete frame node place on reinforced concrete beam 2 is welded on described core steel plate 3; Described core steel plate 3 centers have plug hole 5.

In the embodiment being more preferably, described plug hole 5 is boring or punching, prevents that core steel plate stress is concentrated.The diameter range of described plug hole 5 is 200-500.Be welded on described beam steel 4 on described core steel plate 3 according to the 1:6 setting of bending.

In the embodiment being more preferably, described core steel plate 3 is provided with post reinforced hole, and the post reinforcing bar 6 on described reinforced concrete post 1 is through described post reinforced hole.

In the embodiment being more preferably, described a plurality of reinforced concrete beams 2 refer to the described reinforced concrete beam 2 that is greater than 4.

In the embodiment being more preferably, the proportion 0.4-0.8 between the area of described core steel plate 3 and the sectional area of described reinforced concrete post 1.

The utility model easy construction, formwork is simple, and core steel plate 3 is less than reinforced concrete post 1, can not affect post reinforcing bar, and concreting is also very convenient, and shock resistance is good.The utility model is simple in structure, without the processing of complex parts, easy to use, cheap for manufacturing cost.

More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement etc., within all should being included in protection domain of the present utility model.
