Abstract
The utility model relates to a connection node of an energy-saving fireproof beam column comprising a rectangle-shaped or a square-shaped steel pipe concrete column and a steel beam. The utility model is characterized in that an end plate is fixedly connected with an end part of the steel beam, the end plate is vertical to an axis of the steel beam, the end plate is connected with the steel pipe concrete column through a high strength long bolt, the high strength long bolt passes through the end plate, the steel pipe concrete column and a reinforcing plate disposed on the other side body of the steel pipe concrete column in sequential order. By using the connection node provided in the utility model, the connection strength can be guaranteed, the pouring as well as pounding of the concrete can be facilitated. The connection node of the energy-saving fireproof beam column has advantages of simple production, convenient construction, simple force transmission path, and abilities of promoting the use of the energy-saving fireproof beam column and forging the energy-saving environmental protection society.
Description
Technical field
The utility model relates to a kind of connected node of energy-saving fire-proof construction material.
Background technology
Because rectangle or square steel tube concrete column reasonable stress, steel using amount is little, fireproof performance and economic indicator are good, and at present, increasing building begins to adopt this post form of fracture.But compare with adopting the H steel column, bean column node is comparatively complicated.As shown in Figure 3, for strengthening connected node, traditional way is a welding diaphragm 7 in the steel pipe of bean column node, and diaphragm 7 has through concrete hole; Beam column connects through the mode of bolt weldering at the scene, and there are some shortcomings in this way, as makes complicacy; Operation is many, and speed of application is slow, the field Welding workload is big, and quality is difficult for guaranteeing; Particularly diaphragm influences the pouring tamping of post inner concrete, and when the tubing string cross dimensions was less, this shortcoming was particularly evident.Thus, limited the application of steel core concrete column in steel construction, be unfavorable for that we promote the use of the energy-saving material that this fire prevention economizes the steel material.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of connected node of energy-conservation fire prevention beam column, its is made, and simple, easy construction, Path of Force Transfer are simple and direct, be easy to pouring in the post, help promoting the use of, and make energy saving and environment friendly society.
The utility model solves the technical scheme that its technical problem adopted:
A kind of connected node of energy-conservation fire prevention beam column; Comprise rectangle or square steel tube concrete column and girder steel; End at said girder steel is connected with end plate; The axis normal of end plate and girder steel, said end plate is connected with said steel core concrete column through high strength long bolt, and said high strength long bolt runs through the stiffener on said end plate, said steel core concrete column and the steel core concrete column opposite side shaft successively.
Further, be connected with shear resisting board on the cylinder below the described end plate.
Further again, the lower end flush of the lower end of said stiffener and said shear resisting board or exceed shear resisting board lower end 1-5cm.
The beneficial effect of the utility model is: owing at the bean column node place, adopt the pulling force of the last lower wing plate of stay bolt transfer beams, just need in the tubing string at node place, not weld and be interrupted diaphragm; Because the diameter of stay bolt is less; Improved the perforation condition at node place greatly, and the application of a plurality of stay bolt and stiffener and shear resisting board has guaranteed bonding strength simultaneously again; Thereby both convenient concrete pouring and tamping; Make simultaneously simple, easy construction again, Path of Force Transfer is simple and direct, helps promoting the use of, and makes energy saving and environment friendly society.

Fig. 2 is the structural representation after the utility model partly cut-away;
Fig. 3 is the structural representation of existing bean column node.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2; A kind of connected node of energy-conservation fire prevention beam column comprises the steel core concrete column 1 and girder steel 2 of rectangle, certainly; Steel core concrete column 1 also can be the square-section; Girder steel 2 is H section steel beam or box-girder, is connected with end plate 3 in the end of said girder steel 2, the axis normal of end plate 3 and girder steel 2; Said end plate 3 is connected with said steel core concrete column 1 through some high strength long bolts 4, and high strength long bolt 4 runs through the stiffener 6 on said end plate 3, steel core concrete column 1 and the steel core concrete column opposite side shaft successively.
As depicted in figs. 1 and 2, on 1 cylinder of the steel core concrete column below the end plate 3, be connected with shear resisting board 5, said stiffener 6 is positioned on the outside cylinder of steel core concrete column 1, the lower end flush of stiffener 6 lower ends and shear resisting board 5.
Claims (3)
1. the connected node of an energy-conservation fire prevention beam column; Comprise rectangle or square steel tube concrete column and girder steel; It is characterized in that: the end at said girder steel is connected with end plate; The axis normal of end plate and girder steel, said end plate is connected with said steel core concrete column through high strength long bolt, and said high strength long bolt runs through the stiffener on said end plate, said steel core concrete column and the steel core concrete column opposite side shaft successively.
