Abstract
The utility model discloses a steel column and beam steel connecting joint structure in a stiff structure. A steel column in the stiff structure is a box steel column with a closed section; stiffening partition plates are arranged in the box steel column; H-shaped steel and beam steel are arranged in beams; screw threads are arranged at the ends of the beam steel; arrayed positioning bolts and straight threaded sleeves are welded on connecting surfaces of the steel column and the beam steel one by one; and screw threads are arranged in the straight threaded sleeves. The positioning bolts are preliminarily spot-welded together with the steel column, then the straight threaded sleeves are screwed on the corresponding positioning bolts and welded with the steel column, and the screw thread ends of the beam steel are directly screwed into the straight threaded sleeves, so that the steel column and beam steel connecting joint structure is formed. The steel column and beam steel connecting joint structure solves the difficult problems that stress performance is affected as the section of a steel column is weakened by hole punching and steel penetrating in a stiff structure in the prior art, the hot shortness area of a steel structure is increased to affect stress performance due to heating of the area of the steel column caused by welding according to anchor lengths, and the like. Only reinforcing bar binding is needed during construction, and the construction period of each layer is shortened by two days.
Description
Technical field
The utility model belongs to building structure field, relates to steel column and beam steel connected node structure in a kind of stiffness structure.
Background technology
In China, along with a large amount of construction of high-rise building that highly surpasses 100m, various high-rises are rised sheer from level ground. Steel concrete shear wall structure system commonly used can not adapt to the requirement of safety and the structure function of Super High structure in skyscraper. So stiffness structure is widely used in the super-high building structure. Stiffness structure namely in the beam of traditional reinforced concrete structure, post, increases steel skeleton structure, in the constant situation of structural section, effectively improves the rigidity of structure and intensity. But simultaneously, because the use of steel construction causes again the difficulty at beam, post Nodes reinforcement construction.
In the prior art, the node of column and beam beam steel in the stiffness structure has two kinds with the treatment technology that is connected of steel column: 1. according to anchorage length of steel bar and steel column welding. 2. wear muscle in the steel column punching. There is following defective in these two kinds of methods: first method is directly welded with reinforcing bar and steel column, increases bonding area, and the hot-short area of steel construction is increased, need the later stage reinforcement measure, not only waste material, and prolong the construction period, increased the expenditure of material and labour cost. The second method steelPostMuscle is worn in perforating, not only require machining accuracy high, and in the later stage installation process, require equally installation accuracy high, otherwise can cause the error of floor height, and in wearing the muscle process, increase the probability that changes (expansion) hole, and perforating slackens the steel column cross section affects stress performance, need equally the later stage reinforcement measure, thereby the expenditure of the expense of increasing strengthens construction period.
The Tianjin DTV Building that is located in Mei Jiang business district, Tianjin, first phase overall floorage 150,000 square meters, building general height 155m. The fabric structure form is many-steel coupling beam (steel truss) structure, and 100 years service lives of Building Design, this kind version belongs to first Application in the administrative region, Tianjin. Beam muscle in this fabric structure and the connected node of steel column structure reduce the hot-short phenomenon that the welding of beam muscle produces steel column as far as possible, reduce the steel using amount that is used for structural strengthening, are the research topics that this project projects technical staff needs to be resolved hurrily and implements.
Summary of the invention
The purpose of this utility model is to provide and can greatly reduces the connection workload, a kind of steel column easy to connect that processing charges is lower and beam steel connected node structure。
The utility model for achieving the above object, the technical scheme that adopts is:
Steel column and beam steel connected node structure in a kind of stiffness structure, it is characterized in that: the steel column in the described stiffness structure is the casing steel column, its cross section is sealed, be provided with stiffening diaphragm in it, in beam, be provided with H shaped steel and beam steel, described beam steel termination is provided with screw thread, on the joint face of steel column and beam steel, be welded with one by one the bolt and the straight screw sleeve that are arrangement, straight screw sleeve is provided with screw thread in the hole, bolt is spot-welded together with steel column in advance, then straight screw sleeve is screwed on the bolt and with steel column and welds, and described beam steel screw thread end directly is screwed in the straight screw sleeve, forms steel column and beam steel connected node structure.
Beneficial effect
The utility model is welded on the steel column after adopting straight screw sleeve by the bolt location, one end of beam steel is connected to an end in the straight screw sleeve and consists of formation steel column and beam steel connected node structure, then carry out the colligation of reinforcing bar, thereby solved and adopted punching to wear muscle in the prior art in the stiffness structure to slacken the steel column cross section and affect stress performance and weld the steel column area that causes according to anchorage length and be heated, make the hot-short area of steel construction increase difficult problems such as affecting stress performance, and reduced construction cost, one of reinforcing bar binding only in work progress, every layer of construction period shortened 2 days.
