Adopt shaped steel roof beam to carry out the mode of consolidating to old concrete building to exist in the middle of current a lot of reinforced structure, and emphasize in order to improve the connection of the two, it is also necessary to set up the anchor node between the two, traditional connected mode is at shaped steel roof beam and main part concrete structure wall, the connection process of post, adopt the anchor slab mode of bar planting connection girder steel, this mode has the bar planting volume big, the damage of main structure is big, the difficult former component reinforcing bar of avoiding of bar planting, the construction difficulty, the quality is difficult to guarantee the scheduling problem, in order to solve foretell technical problem, the present case provides following solution:
referring to fig. 1 to 3, a structural steel beam and concrete wall beam node anchoring connection structure is provided on a shear wall 1, and includes: a plurality of original concrete beam longitudinal ribs 3 extending from the inside of the shear wall 1 to the outside of the shear wall 1, and a node area is formed between the two original concrete beam longitudinal ribs 3 which correspond up and down; the section steel beam assembly 4 is arranged inside the node area; the connecting steel bars 5 are welded at the upper flange and the lower flange of the section steel beam assembly 4, and the connecting steel bars 5 are welded with the original concrete beam longitudinal bars 3; and filling slurry filled in the node region.
Furthermore, the shear wall 1 toward the direction that former concrete beam longitudinal reinforcement 3 set up extends and is provided with one and reserves concrete corbel 2.
Firstly, determining a range to be reserved at a wall beam joint which is about 500mm away from a shear wall 1 in a marking and positioning mode, then cutting an original structure girder to cut off an unnecessary concrete structure, then chiseling and finely repairing the reserved original structure girder head joint in a manual electric hammer mode, reserving a reserved concrete corbel 2 which is 200mm long and 250mm high at the bottom of a structure girder to be used as a supporting point of a newly-built steel girder head shear key, reserving an original concrete girder longitudinal rib 3 in the chiseling process, and after chiseling the original structure girder head and removing the reserved concrete corbel 2, cleaning a base layer of an original structure concrete contact surface and removing surface dust before installation of a section steel girder assembly 4 to lay a foundation for installation of the section steel girder assembly 4.
When installing shaped steel girder assembly 4, at first, hoist shaped steel girder assembly 4 earlier, hoist it to former concrete beam indulge muscle 3 and reserve concrete bracket 2 on the position, form preliminary installation, afterwards, welded connection reinforcing bar 5 on the upper and lower wing of shaped steel girder assembly 4, and connecting bar 5 welds together with former concrete beam indulges muscle 3 again, form preliminary fixed, later stage rethread fills the mode of thick liquids and forms final fixed, the work of bar planting all can't be planted at whole fixed in-process, and except getting rid of unnecessary structure girder part earlier stage, in the installation of later stage is fixed, need not at destruction shear force wall 1, reserve concrete structures such as concrete bracket 2, the more stability of the overall framework of follow-up formation.
In order to improve the fixing effect of the welded connecting steel bar 5 and the welded original concrete beam longitudinal bar 3 and ensure that the connecting steel bar 5 and the welded original concrete beam longitudinal bar 3 are not easy to deform or pour slurry, a plurality of opening stirrups 6 are bound outside the connecting steel bar 5 and the original concrete beam longitudinal bar 3 and form a bound through the opening stirrups 6, wherein the opening stirrups 6 are open stirrups when normal stirrups cannot be used, such as I-shaped steel in section steel concrete, and the opening stirrups are adopted and have shapes similar to a zone character without a fork and are symmetrical left and right.
In the whole section steel beam assembly 4 and concrete structure's connection process, in order to improve the intensity after the connection, some specific settings have been made in section steel beam assembly 4's inside, specifically are: the section steel beam assembly 4 comprises a section steel beam 41, a node plate 42 fixedly connected to the section steel beam 41 and close to one side of the node area, and a plurality of section steel beam anchor bars 43 welded to the node plate 42, wherein the section steel beam anchor bars 43 point to the shear wall 1, and after the slurry is poured, the effect of building reinforcing steel bars in a building can be achieved, so that the building strength after forming is improved.
In this embodiment, the shaped steel beam anchor bars 43 are arranged in three rows on the transverse direction of the end portion of the shaped steel beam 41, four rows are arranged on the longitudinal direction of the end portion of the shaped steel beam 41, twelve shaped steel beam anchor bars 43 are arranged, the shaped steel beam anchor bars 43 are basically distributed in the whole node area in a mode of arranging three rows in the transverse direction and four rows in the longitudinal direction, the node area serving as a connection area is provided with steel bars, and the overall strength is stably enhanced.
And because the design of the reserved concrete corbel 2 causes all the steel beam anchor bars 43 to have no way of being equal in length, in order to adapt to the length of each position, the steel beam anchor bars 43 are completely densely distributed in the whole node area, so that the length of the steel beam anchor bars 43 above the reserved concrete corbel 2 is greater than the length of the steel beam anchor bars 43 on the side direction corresponding to the reserved concrete corbel 2, and the steel beam anchor bars 43 in the whole node area are fully arranged.
After the section steel beam assembly 4 is connected with the shear wall 1, after the section steel beam assembly is put into use, the section steel beam assembly 4 is inevitably subjected to a shear force, and if the shear force is applied to a node of an anchor connection, the damage to the node is larger, so in order to strengthen the shear resistance of the anchor node, the section steel beam assembly 4 further comprises a shear key 44 welded on the section steel beam 41, wherein the shear key 44 is usually vertically welded on a horizontal steel plate at the bottom surface of a column base by using a thicker channel steel or an I-steel and is embedded in a shear groove reserved in a concrete foundation, the shear key 44 is usually secondarily poured by using micro-expansion concrete, the primary function is to resist the shear force at the bottom of the column and prevent the column base plate and the top surface of foundation concrete from sliding, in order to ensure that the shear key 44 has a stable installation space, the shear key 44 is arranged above the reserved concrete corbel 2, and when the reserved original concrete beam longitudinal bar 3 collides with the shear key 44, the shear key 44 is subjected to avoidance adjustment and is welded again.
In this embodiment, in order to improve the quality of the filled slurry, the filled slurry is a high-strength non-shrinkage grouting material, the high-strength non-shrinkage grouting material is prepared by using cement as a cementing material and adding german imported additives, pure natural aggregates and other materials, and the high-strength non-shrinkage grouting material can be used after being stirred by adding water on site, and has the characteristics of no shrinkage, large fluidity and high strength.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
