Abstract
The utility model relates to a connecting joint of a round steel pipe column and a concrete beam. The connecting joint comprises a steel pipe column body, the left end of a steel corbel is fixedly connected with the steel pipe column body, and the upper surface of the right end of the steel corbel is fixedly connected with steel bars connected with sleeves. The lower surface of the right end of the steel corbel is fixedly connected with steel bars connected with sleeves. The problem that when existing double-layer steel bars are connected with a steel pipe column through a steel corbel, lower layer connection needs overhead welding, and therefore the connecting joint has great popularization value.
Description
Technical field
The utility model relates to architectural design field, specifically relates to a kind of round steel tubing string and concrete beam connected node.
Background technology
It is difficult point of Steel concrete combining structure that round steel tubing string is connected with reinforcing bar in concrete beam, and at present conventional concrete beam, the connected mode of reinforcing bar and steel pipe column has two kinds.As shown in Figure 1, way is that in concrete beam, reinforcing bar welds by steel bushing and steel pipe column, the method advantage is that power transmission is direct, shortcoming is because steel pipe column external surface is circular configuration, have certain radian, and barrel end is plane structure, the position that sleeve does not contact with steel pipe column) need welding to fill, this just causes welding job amount excessive, increases human cost.As shown in Figures 2 and 3, the method is to be connected with steel corbel by reinforcing bar, the connected mode of reinforcing bar welding in steel corbel and concrete beam, this connected mode is that a placing of reinforcement is more effective to concrete beam, but while having two placing of reinforcements for concrete beam, second row reinforcing bar needs overhead welding, and the difficulty of welding strengthens, and the quality of weld seam can not ensure, have potential safety hazard.
Notice of authorization number is the node structure that the Chinese patent literature of CN201598733U has been recorded a kind of steel core concrete column and reinforced concrete beam, and it comprises steel core concrete column, is fixed on the node on described steel core concrete column and is overlapped on many reinforcing bars on described node; Described node comprises axial limiting mechanism, and described many reinforcing bars are connected with described axial limiting mechanism respectively; This node structure also comprises concrete beam, and this concrete beam contains described many reinforcing bars and described axial limiting mechanism.The document by increasing the end of the fixing reinforcing bar of axial limiting mechanism on bracket.But, due to the existence of position-limit mechanism, can limit the quantity of single reinforcing bar, in the time that needs connecting reinforcement is too much, just need the extra bracket that increases, increase construction cost.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of Novel round steel tubing string and concrete beam connected node are provided.
The utility model adopts following technical proposals:
A kind of round steel tubing string and concrete beam connected node, comprise steel pipe column body, and the left end of steel corbel is fixedly connected with steel pipe column body, and the upper surface of steel corbel right-hand member is fixedly connected with reinforcing bar, and reinforcing bar is connected with sleeve; The soffit of steel corbel right-hand member is fixedly connected with reinforcing bar, and reinforcing bar is connected with sleeve.
Preferably, when the connected mode of described reinforcing bar and steel corbel is one side welding, fusion length is not less than 10 times of bar diameter.
Preferably, when the connected mode of described reinforcing bar and steel corbel is double welding, fusion length is not less than 5 times of bar diameter.
Preferably, described sleeve is connected with reinforcing bar in concrete beam.
The beneficial effects of the utility model are: before installation, directly steel corbel is fixedly connected with steel pipe column, steel corbel is fixedly connected with reinforcing bar, and reinforcing bar is connected with sleeve, only need at the construction field (site) upper and lower placing of reinforcement in concrete beam to be connected with sleeve respectively.Avoid the problem that in concrete beam, reinforcing bar is direct by sleeve and steel pipe column connecting welding workload is large, solved the problem that need weld in the overhead position when the interior second row reinforcing bar of concrete beam is connected with steel corbel simultaneously, improve operating efficiency, also ensured weldquality, eliminated safe hidden trouble simultaneously.
Brief description of the drawings:
Fig. 1 is that existing reinforcing bar is by sleeve and steel pipe column johning knot composition;
Fig. 2 is that existing reinforcing bar is by steel corbel and steel pipe column johning knot composition;
Fig. 3 is that the A-A of Fig. 2 is to sectional view;
Fig. 4 is structure chart of the present utility model;
Fig. 5 is that the B-B of Fig. 4 is to sectional view;
Wherein: 1, steel pipe column body, 2, need welding position, 3, sleeve, 4, reinforcing bar, 5, steel corbel.
Detailed description of the invention:
Embodiment 1: a kind of round steel tubing string and concrete beam connected node, its structure is as shown in Fig. 4-5: comprise steel pipe column body 1, the left end of described steel corbel 5 is fixedly connected with steel pipe column body 1, and the upper surface of steel corbel 5 right-hand members is fixedly connected with reinforcing bar 4, and reinforcing bar 4 is connected with sleeve 3; The soffit of steel corbel right-hand member is fixedly connected with reinforcing bar 4, and reinforcing bar 4 is connected with sleeve 3 by mantle fiber; Described reinforcing bar 4 is one side welding with the connected mode of steel corbel, and fusion length is not less than 10 times of reinforcing bar 4 diameters; Described sleeve 3 is connected with reinforcing bar in concrete beam by mantle fiber.
This programme is directly fixedly connected with steel corbel 5 before installation with steel pipe column body 1, steel corbel 5 is fixedly connected with reinforcing bar 4, reinforcing bar 4 be connected with sleeve 3 by mantle fiber, only need at the construction field (site) be connected with sleeve 3 respectively by mantle fiber after will be in concrete beam upper and lower placing of reinforcement chopping.Avoid the problem that in concrete beam, reinforcing bar is direct by sleeve 3 and steel pipe column body 1 connecting welding workload is large, solved the problem that need weld in the overhead position when the interior second row reinforcing bar of concrete beam is connected with steel corbel 5 simultaneously, improve operating efficiency, also ensured weldquality, eliminated safe hidden trouble simultaneously.
Embodiment 2: a kind of round steel tubing string and concrete beam connected node, its structure is still as shown in Fig. 4-5: the places different from embodiment 1 are, and described reinforcing bar 4 is double welding with the connected mode of steel corbel 5, and fusion length is not less than 5 times of bar diameter.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection scope of the present invention.
