Abstract
The utility model provides a steel pipe joint of a concrete column and beam (board). The joint comprises a steel pipe which is filled with concretes at core, and tensile steel plate and a shear resistant steel plate which are installed on the steel pipe. The tensile steel plate and the shear resistant steel plate are respectively provided with a supporting steel bracket and a shear resistant steel bracket. The joint comprises a shear resistant steel hoop which is fixed on the steel pipe by a connecting fastener. The steel pipe is a diameter chanegable steel pipe. The steel pipe is provided with a flange plate which is used for connecting two diameter changeable steel pipes. The utility model can not weaken the strength of concrete filled steel pipes, can meet the construction measure of means under a site operation condition, and organically combines the external transmission force and the internal transmission force.
Description
The utility model relates to a kind of steel core concrete column and beam (plate) contact.
The moment of flexure of steel tube concrete beam (plate) end generally is by twin beams or non-uniform beam, is directly delivered to the steel pipe of steel core concrete column; And the shearing of beam (plate) end generally is by being directly welded in steel corbel on the steel pipe, hanging that muscle or annular rib etc. are delivered to the outside power transmission method of core concrete or by adopting cover plate, interlayer diaphragm load to be passed to the inside power transmission method of core concrete.
The obvious deficiency of above power transmission method just is:
1. when adopting outside power transmission, the welding residual stress that welded unit produced on steel pipe will weaken the cuff effect of steel pipe walls to core concrete;
2. when adopting inner power transmission, cover plate, interlayer diaphragm etc. influence the compactness of steel pipe inner concrete again with the concrete pouring of overslaugh;
3. traditional twin beams or non-uniform beam have weakened being connected of post and beam (plate), influence the stressed of beam (plate);
4. the precision of component assembly often is subjected to the restriction of construction condition;
5. the bearing capacity of steel core concrete column is weakened greatly, and especially the weakening of fatigue stress is more obvious under the effect of dynamic loading.
In view of above reason, the purpose of this utility model is for a kind of intensity that can not weaken concrete filled steel tube is provided, can satisfy the member construction measure of construction condition again, steel core concrete column and beam (plate) contact that outside power transmission and inner power transmission are organically combined.
The purpose of this utility model is achieved in that the concrete steel pipe of core filling in the utility model, be loaded on tension steel plate, anti-shear steel plate on the steel pipe, have respectively on tension steel plate and the anti-shear steel plate and support steel corbel and shearing resistance steel corbel (referring to Fig. 1～Fig. 6).
Between above-mentioned steel pipe and tension steel plate the tension steel hoop (referring to Fig. 1, Fig. 3) that is connected with the tension steel plate is arranged.
Have in the above-mentioned contact by connecting securing member and be fastened on shearing resistance steel hoop (referring to Fig. 1) on the steel pipe, by shearing resistance steel pipe hoop, shearing is delivered to concrete filled steel tube, and welding residual stress is all digested by the shearing resistance steel hoop, steel pipe to steel core concrete column has no effect, connect securing member simultaneously and increased shearing friction power between core concrete and steel pipe again, curved outside power transmission is inner power transmission.
Above-mentioned steel pipe is the reducing steel pipe, have on the steel pipe two reducing steel pipe flange connecting dishes (referring to Fig. 4) up and down, make concrete beam (plate) shearing adopt inner mode of transfer force to be directly delivered to the steel core concrete column internal core, improve steel core concrete column and the reliability that beam (plate) is connected, its ability of bearing dynamic loading is improved.
Above-mentioned reducing steel pipe is fixed on (referring to Fig. 4) on the flange by clamp.
Bleeder port (referring to Fig. 2) is arranged on the above-mentioned tension steel plate.
In steel core concrete column and beam (plate) contact, steel core concrete column is main load-carrying member, is made up of steel pipe and its core concrete, because the cuff effect of steel pipe improves the supporting capacity of steel core concrete column greatly.The tension steel plate is beam (plate) moment of flexure Force transmission parts, is used to connect steel pipe column two end carriages (plate) steel bar stress; With the tension steel hoop, play the reinforcing ring effect that the restriction steel core concrete column outwards expands simultaneously, help the internal delivery of shearing on the steel pipe.The tension steel plate can be circle or square with the layout of beam (plate).Anti-shear steel plate is the shearing transmission member of concrete beam (plate), also plays the reinforcing ring effect simultaneously.Anti-shear steel plate and the welding of shearing resistance steel corbel with the pressure that steel concrete transmits, are delivered to the shearing resistance steel corbel.The shape of anti-shear steel plate is subjected to its shearing (die-cut) line and decides, and is generally square in beam, is circular in die-cut plate.Concrete beam (plate) directly is welded on the shearing resistance steel hoop with the connecting elements shearing resistance steel corbel of post, by the shearing resistance steel hoop shearing is delivered to concrete filled steel tube, and welding residual stress is all by shearing resistance steel hoop digestion, and the steel pipe of steel core concrete column is had no effect; High-strength bolt has increased the shearing friction power between core concrete and the steel pipe again simultaneously, becomes outside power transmission and is inner power transmission.Rely on flange two reducing steel pipes connection up and down, make concrete beam (plate) shearing adopt inner mode of transfer force to be directly delivered to the steel core concrete column internal core, improve the reliability that steel core concrete column is connected with beam (plate), its ability of bearing dynamic loading is improved, strengthened the anti-fatigue ability of contact.
The utility model steel core concrete column and beam (plate) contact can not weaken the intensity of concrete filled steel tube, can satisfy the member construction measure of construction condition again, and outside power transmission and inner power transmission organically are joined together.Have member stress clear and definite reliable, give full play to component load-bearing ability and typing characteristics of producing in batches, with its design safety rationally, quick construction, expense economy, and be widely used in underground structure, surface structures and bridge engineering.Wherein, possess the ability of directly bearing the heavy duty dynamic loading, be specially adapted to underground railway, underground garage and other bears the structure of dynamic loading especially to adopt reducing steel pipe and flange contact.
