Description

The syndeton of a kind of new increasing steel beam and concrete column
Technical field
The utility model belongs to structural engineering technical field, is specifically related to the syndeton of a kind of new increasing steel beam and existed concrete bridge post.
Background technology
Along with the industrialized high speed development of China, quite a few industrial construction can not adapt to new Production requirement at present, but due to the reason planned or manage, this industrial construction cannot be removed and reconstruct, and needs to transform its inside for this reason, wherein just relates to a kind of floor displacement transformation, all remove by original floor transverse member, retain vertical member, then rebuild floor by new calibration is high, be floor displacement.
At present, existing concrete column and newly-increased section steel beam joint structure and construction method is not all provided in the existing specification of China, standard, but this kind of way can often run in a lot of improvement project, and increasing along with transformation project, running into this kind of connection way also can be more, a lot of people runs into this kind of situation and often has no way of doing it, and does not know how to solve.
Summary of the invention
For the problems referred to above, the utility model provides a kind ofly to be had good node overall performance, good anti-seismic performance, achieves strong node, the new increasing steel beam of design concept of weak component and the syndeton of concrete column.
For solving the problem, the technical scheme that the utility model is taked is: the syndeton of a kind of new increasing steel beam and concrete column, comprise concrete column and be fixed on the C-type steel plate of its three sides, C-type steel plate is by base plate and be connected to the epipleural at base plate two ends and lower side panel forms, be cast with structural adhesive layer between concrete column and C-type steel plate, the base plate of C-type steel plate is welded with suspension column floor and new increasing steel beam.Described C shape steel plate is utilized by a block plate that folder is folding forms or adopt vertical position welding groove welding to form.New increasing steel beam is directly welded on the base plate of C shape steel plate, and suspension column floor is for reinforcing the connection between C-type steel plate and new increasing steel beam.
Described new increasing steel beam comprises upper flange, lower wing plate and web, wherein, upper flange, adopts groove welding between lower wing plate and suspension column floor, adopts fillet weld seam between web and suspension column floor.The wider protective gas laminar flow layer that groove welding produces effectively can protect dark narrow groove weld and its stability has been enough to weld seam cap.Fillet weld seam is exactly have weld seam in the both sides of suspension column floor, and its effect is all make weldment more firm.
For making C-type steel plate and concrete column fit tightly, the base plate of described C-type steel plate be right angle between epipleural and lower side panel and be connected.
The described epipleural of C-type steel plate and the outer end of lower side panel are run through turnbuckle.C shape steel plate is clamped at outside concrete column through bolt hole by described turnbuckle.
For ensureing that C-type steel plate is firmly installed on concrete column periphery, described C-type steel plate base plate and upper and lower side plate are all fixed on concrete column by high-strength expanding bolts.C-type steel plate is anchored on concrete column by pad and double-deck nut by high-strength expanding bolts.
The utility model solves the connectivity problem between new increasing steel beam and existing concrete column, there is good node overall performance and anti-seismic performance, achieve the design concept of strong node, weak component, the utility model structure be simple, easy accessibility, installation site is arbitrarily flexible; Solve the existing concrete beam and new increasing steel beam unstable problem that do not arrange built-in fitting during installation, also solving existing building cannot remove, and causes transformation project difficult problem.

Detailed description of the invention
As shown in the figure, the syndeton of a kind of new increasing steel beam and concrete column, comprise concrete column 1 and be fixed on the C-type steel plate 3 of its three sides, C-type steel plate 3 is by base plate 33 and be at right angles connected to the epipleural 31 at base plate 33 two ends and lower side panel 32 forms and base plate 33, epipleural 31, lower side panel 32 are provided with multiple high-strength expanding bolts 4, and C-type steel plate 3 is anchored on concrete column 1 by pad 5 and double-deck nut 6 by high-strength expanding bolts 4.The epipleural 31 of described C-type steel plate 3 and the outer end of lower side panel 32 are run through turnbuckle 9.Be cast with structural adhesive layer 2 between concrete column 1 and C-type steel plate 3, the base plate 33 of C-type steel plate 3 is welded with suspension column floor 7 and new increasing steel beam 8.Described new increasing steel beam 8 comprises upper flange 81, lower wing plate 82 and web 83, wherein, upper flange 81, adopts groove welding between lower wing plate 82 and suspension column floor 7, adopts fillet weld seam between web 83 and suspension column floor 7.
Construction sequence is as follows:
Step one: determine installation site, measurement size, draws C-type steel and to harden composition, make C steel plate member, and in the machine drilling of C shape surface of steel plate, determine screwhole position;
Step 2: in fixed installation site, smearing structure glue-line, places C-type steel plate;
Step 3: empty at concrete column surface power auger according to C-type steel plate screwhole position, first in the side of new increasing steel beam, adopts the method for chemically-planted steel bar to implant high-strength expanding bolts, rotates high-strength expanding bolts, make it be fixed on inside concrete column;
Step 4: adopt and use the same method, is rotated high-strength expanding bolts at the two ends of C-type steel plate, fixation of C shape steel plate, and is clamped by double-deck nut, prevent from loosening;
Step 5: tighten turnbuckle, utilizes the pulling force of turnbuckle to be clamped on concrete column by C-type steel plate;
Step 6: install new increasing steel beam, is welded on suspension column floor and new increasing steel beam on C shape steel plate;
Step 7: suspension column floor and new increasing steel beam are welded to connect, upper and lower wing plate adopts groove welding, and web adopts fillet weld seam.
