Abstract
The invention relates to a building construction method, in particular to a non-steel-column type steel beam connection construction process, which solves the problem of the connection between a steel beam and a concrete structural column during the construction. The process comprises the following steps of: firstly, fabricating the steel beam and placing a template of the steel beam between concrete columns; secondly, hoisting the steel beam, putting the steel beam on the template, installing stirrups around a concrete column tendon above the steel beam, welding the stirrups with the tendon; thirdly, installing waist ribs, installing steel beam stirrups around the steel beam, installing beam penetrating steel bars which pass through the upper and lower web plates of the steel beam and are connected with the steel bars on the middle part of the concrete column through nut sleeves, installing stirrups around the concrete column steel bars on the side of the steel beam; fourthly, applying hooks onto the stirrups; and finally, erecting the template around the steel beam for pouring concrete. The construction process solves the problem of the connection between the reinforced concrete column and the steel beam without a steel column.
Description
Technical field
The present invention relates to a kind of construction techniques, be specially a kind of steel column free type steel beam joint construction process.
Background technology
In present high-building construction, the connected mode of existing post and section steel beam is to be connected with the welding of the steel column in the shaped steel beam and column or with high-strength bolt, and it is as a whole that the shaped steel beam and column is connected.But when running into special designing requirement, for example the second layer at main building is designed to conversion coating, and for frame props up structure, some of beams are steel reinforced concrete structure, and its frame-supporting column requires to be reinforced concrete post, design mode steel column not in the post.So just can't still must finish this construction task again, and safety also to reach the effect that is connected with section steel beam with the post that has used shaped steel according to existing technology construction.
Summary of the invention
The present invention is for the problem that is connected that solves section steel beam and concrete structure column under construction and a kind of steel column free type steel beam joint construction process is provided.
The present invention is realized by following technical scheme, a kind of steel column free type steel beam joint construction process, may further comprise the steps: at first make section steel beam, on section steel beam, bore the split bolt hole of reinforcing template, manufacture the straight thread silk head of the reinforcing bar upper end of passing the section steel beam frange plate at concrete column middle part then, between concrete column, install the template of section steel beam, mount type girder steel steel supports ironware on template, muscle at the bottom of the mount type girder steel again, some vertical rods are adopted in the template below, divide two rows to support, the vertical pole ' s span in the row guarantees to be no more than 50 centimeters to satisfy the weight of girder steel.
Secondly, the type lifting girder steel is placed on section steel beam on the template, the end muscle of other section steel beam that other and this section steel beam intersect is installed, wherein 50% end muscle passes section steel beam, other 50% end muscle are welded on the section steel beam, install the beam steel of wearing of the frange plate up and down that passes section steel beam additional in the position of concrete column upper end, the reinforcing bar of wearing beam steel and concrete column middle part is connected by ut socket, concrete column tendon on section steel beam top installs stirrup additional on every side and welds together, the waist muscle of the main muscle on mount type girder steel top and side again, again section steel beam week side top master's muscle and the lower bottom muscle around mount type girder steel stirrup, at last 90 degree on the reinforcing bar of concrete column week side are bent anchor on concrete beam or in the concrete slab, around the concrete column reinforcing bar that is positioned at the section steel beam side, install stirrup additional, add pull hook again on stirrup, the pull hook other end is welded on the section steel beam, forms steel mesh reinforcement on section steel beam, at last at section steel beam peripheral branch template, concreting.
The invention solves under the situation of no steel column the problem of using reinforced concrete post to be connected with section steel beam.Reasonable in design, reliable construction quality can reach the safety requirements of design fully.Adopt two reinforcing bars that belong to concrete column to penetrate section steel beam Ji listrium up and down, the curved method that anchors in the concrete beam, the bonding strength of enhanced type steel and concrete column in the construction.When not contour section steel beam or reinforced concrete beam and section steel beam crossed one another cross-under, the job practices that adopts section steel beam bottom end muscle to connect guaranteed during construction that the end muscle of low beam has 50% to pass section steel beam, and all the other 50% are welded on the web.The post, beam main tendon of wearing section steel beam adopt the mode of straight screw sleeve reinforcing bar jointing, the solution of essence post, the beam main tendon difficult problem that can't put in place.In order to solve the accurate position in the girder with rolled steel section en cased in concrete that section steel beam in the end forms, adopt in the section steel beam bottom steel to be set and to support, accurate to guarantee when the lifting section steel beam shaped steel depth of beam, axial location.The setting of stirrup is encrypted at section steel beam and reinforced concrete post node place, has satisfied the force request of column cap.Structure design (the girder with rolled steel section en cased in concrete layback muscle of structure design is soldered on the girder steel) in that the distributing bar of section steel beam side is established pull hook can closely link together reinforcing bar and section steel beam.
