Abstract

The utility model belongs to the technical field of civil engineering and particularly relates to a steel column prepressing bending-resistant type connecting node. The connecting node comprises an H-shaped frame column, shearing-resistant high-strength bolts, clamp plates, high-strength bolts, flange plates and stiffening plates, wherein the H-shaped frame column is divided into an upper section and a lower section; the end parts of flange girths at the joint of the upper section and the lower section are flattened by milling and propped against each other; the clamp plates are arranged on two sides of the web plates of the upper and the lower sections of the H-shaped frame column; the web plates of the upper and the lower sections of the H-shaped frame column are connected with the two clamp plates through the shearing-resistant high-strength bolts; and the flange plates and the stiffening plates are arranged on the web plates of the upper and the lower sections of the H-shaped frame column respectively, and the two flange plates are connected with each other through the four high-strength bolts in longitudinal distribution, so as to achieve the function of bearing designed pressure and designed bending moment and ensure the rigid connection property of the connecting node. Through the utilization of the precompression to the flat milled end surfaces of the flange girth, which is generated after the long-screw friction type high-strength bolts applies pre-tension, the defects of large thickness, high steel consumption and high possibility of welding deformation of the common flange plate are overcome.

Description

Steel column precompressed bending resistance type connected node
Technical field
The utility model belongs to technical field of civil engineering, is specifically related to the on-the-spot splicing of a kind of steel wood combination construction system steel column node, i.e. steel column precompressed bending resistance type bolt connects, can extensive use in steel wood combination construction and light section steel structure civilian construction.
Background technology
In light section steel structure and steel wood combination construction, its agent structure system is generally the transverse plane framework, vertically the intercolumniation support system at present.For improving the post lateral deformation stiffness, give full play to the strength of materials of steel, reduce steel using amount, generally beam column building site splicing design of node is become to be rigidly connected.Common practice is: web adopts high-strength bolt to connect, or all adopts butt welding, adopts the groove butt weld of complete penetration to connect usually to the H shaped column edge of a wing.Above connected mode field Welding workload is bigger, and is unfavorable to the construction cost and the duration decline of suitability for industrialized production assembled steel wood or lightweight steel construction.The utility model adopts rational detail structure, is convenient to building site assembling construction, to reduce construction cost, increases economic efficiency.
Summary of the invention
The utility model mixes dwelling house (or office building) to five to six layers of steel wood, and a kind of steel column precompressed bending resistance type connected node is provided.The steel column scene all connects with bolt, to replace the weldering of steel column field joint, realizes rapid construction, and guarantees component strength and rigidity.
The utility model is taked following technical scheme:
A kind of steel column precompressed bending resistance type connected node; Form by H shape frame column 1, shearing resistance high-strength bolt 2, clamping plate 3, high-strength bolt 4, flanged plate 5 and stiffener 6; Wherein: H shape frame column 1 is divided into epimere and hypomere two parts, and it is tight that epimere and hypomere joint top flange mill flat-top; The web of H shape frame column 1 epimere and the web both sides of hypomere are provided with clamping plate 3, and the web of said H shape frame column 1 epimere and the web of hypomere are connected through shearing resistance high-strength bolt 2 with two clamping plates 3; Be equipped with flanged plate 5 and stiffener 6 on the web of H shape frame column 1 epimere and the web of hypomere; Two flanged plates 5 connect through 4 high-strength bolts that vertically distribute 4; To reach the effect of bearing design pressure, design moment, guarantee the character that rigidly connects of connected node.
In the utility model, said stiffener 6 one ends are fixed on the flanged plate 5.Said stiffener 6 is positioned at the inboard of flanged plate 5, forms reverse flanged plate.
In the utility model, the epimere of said H shape frame column 1 and hypomere joint are positioned at floor height 1/3~1/4 place.
In the utility model, carry out the frame column building site when installing, earlier with two-sided clamping plate connection, during beginning shearing resistance high-strength bolt 2 is tightened by plain bolt, the stretch-draw high-strength bolt 4 again, and then shearing resistance high-strength bolt 2 is applied pretension.
The utility model has the advantages that:
(1) vertical high-strength bolt is used in the steel column splicing, after it applies pretension, planar end surface is milled on the edge of a wing will produce precompression, and the frictional force shearing resistance that utilizes precompression to produce utilizes the increase and decrease bending resistance of compressive stress.Effectively utilized the bending resistance shear resistance that the high pretension of high-strength bolt produces, good integrity, distortion are less.And screw rod increases, and helps accurately applying pretension.Shearing resistance is accomplished by high-strength bolt and clamping plate, gets final product by the common method design, calculates easy.This node power transmission mechanism is clear and definite, so the bending rigidity of node is big and steady and continuous.
(2) utilize the long bolt friction type high strength bolt to apply behind the pretension precompression that planar end surface produces is milled on the edge of a wing, it is bigger to have overcome general flange plate thickness, the shortcoming that steel using amount is big.
(3) this node building site jointing positions of having saved post is provided with the workload of otic placode, has not only reduced cost, and has improved on-the-spot installation effectiveness.
