Abstract
The utility model discloses a novel steel-concrete combined panel node which comprises a welding honeycombed steel beam, a close-packed compound continuous spiral hoop or a high-tensile concrete column constrained by a welding ring type hoop, a connecting end plate and a high tensile connecting bolt, wherein the end part of the steel beam is welded and fixed on the connecting end plate which is locked on the side surface of the concrete column by a high-strength connecting bolt. Compared with the prior art, the novel steel-concrete combined panel node has the benefits that the steel beam in the traditional combined panel node is the common solid web steel beam, but the steel beam in the novel steel-concrete combined panel nod is the weld honeycombed steel beam, therefore, the combined panel node can save steel products and lighten the structure self weight; simultaneously as in the novel steel-concrete combined panel node, the common concrete column in the traditional combined panel node is replaced with the close-packed compound continuous spiral hoop or the high-tensile concrete column constrained by the welding ring type hoop, the high-tensile concrete column with smaller cross section can realize bigger bearing capability, thus solving the problem that the limit value of axial compression ratio and the column cross section of the common concrete column are overlarge, also solving the problem of the brittle failure of the short column, saving the concrete and lightening the structure self weight.
Description
Technical field
The utility model relates to field of civil engineering, specifically is a kind of steel-concrete combined joint.
Background technology
Combined joint is the important component part of steel-concrete combined structure, the steel-concrete combined joint is the combined joint of present extensive use, the structure of steel-concrete combined joint generally comprises girder steel, concrete column, connect end plate and connecting bolt, girder steel mainly contains worker's section steel beam and T-steel beam, the steel-concrete combined joint of forming with worker's section steel beam and concrete column is an example, the end of worker's section steel beam is welded on and connects on the end plate, connect end plate and link together, can improve the carrying and the deformability of node by the effect of contraction that connects end plate by connecting bolt and the concrete column that is embedded in the concrete column.This traditional steel-concrete combined joint, because girder steel adopts real abdomen girder steel, concrete column adopts the ordinary concrete post, real abdomen girder steel causes dead load to increase, the waste steel, simultaneously, satisfy the ratio of axial compressive force to axial compressive ultimate capacity of section requirement and cause the cross dimensions of concrete column excessive, also increased dead load.Therefore limited the application of combined joint to a certain extent.
The utility model content
The purpose of this utility model provide a kind of deadweight light, can save steel and concrete novel steel-concrete combined joint.
The technical solution adopted in the utility model is: a kind of novel steel-concrete combined joint, comprise girder steel, concrete column, connection end plate and high-strength connecting bolt, the end of girder steel is weldingly fixed on and connects on the end plate, connects end plate and locks on the side of concrete column by high-strength connecting bolt; Above-mentioned girder steel is the welding Steel Castellated Beams; Above-mentioned concrete column is the close high-strength concrete column of putting compound continuous helical stirrup or welding ring type stirrup restraint.
Above-mentioned welding Steel Castellated Beams is the hexagonal hole welding Steel Castellated Beams that the cross section is worker's shape.
Above-mentioned connection end plate is that overhanging formula connects end plate.
The utility model beneficial effect compared with prior art is: with respect to girder steel in the conventional combination node is common real abdomen girder steel, and girder steel is the welding Steel Castellated Beams in the utility model, thereby combined joint can be saved steel, alleviate dead load; Simultaneously owing in the utility model ordinary concrete post in the conventional combination node replaced with the close high-strength concrete column of putting compound continuous helical stirrup or welding ring type stirrup restraint, this high-strength concrete column of small cross sections just can be realized bigger bearing capacity, thereby can solve the limit value of axial compression ratio and the excessive problem of column section of general concrete column, also can solve short column brittle fracture problem, and save concrete, alleviate dead load.

The specific embodiment
A kind of novel steel-concrete combined joint of the present utility model, as Fig. 1,2, shown in 3, comprise girder steel 1, concrete column 2, overhanging formula connects end plate 3 and the high-strength connecting bolt 4 of plural groups, high-strength connecting bolt 4 is embedded in the concrete column 2 and the side of stretching out concrete column 2 in advance, the end of girder steel 1 is weldingly fixed on overhanging formula and connects on the end plate 3, the end of girder steel 1 is connected end plate 3 with overhanging formula and is connected by weld seam 5, overhanging formula connects end plate 3 and locks on the side of concrete column 2 by high-strength connecting bolt 4 (attaching nut), wherein, girder steel 1 is the hexagonal hole welding Steel Castellated Beams of worker's shape for the cross section, the hexagonal hole honeycomb is positioned at the belly of beam, does not influence the stress performance of beam; Concrete column 2 puts by close that compound continuous helical stirrup or complex root are close puts composite welding ring type stirrup 21 and complex root steel bar stress 22 forms cage of reinforcement, and builds high-strength concrete 23 and form.
During construction, at first the end with girder steel 1 is connected end plate 3 by weld seam 5 connections with overhanging formula, and then overhanging formula connection end plate 3 is through on the connecting bolt 4, by nut screwing clamping connecting bolt 4, just forms novel steel-concrete combined joint of the present utility model.
During use, new reinforcing steel bar of the present utility model-concrete combined joint and beam, post, floor are connected into composite frame structure, bear horizontal loading and vertical load.
Above-mentioned embodiment is a kind of embodiment of the present utility model, and simultaneously the embodiment of making based on claim and expansion thereof is protection domain of the present utility model.
