The utility model discloses the tie-beam of main building and skirt room is strength nature concrete structure, is a integrated configuration that forms by steel skeleton outsourcing reinforced concrete. The steel skeleton and the high-strength concrete are configured to be mutually constrained, so that the stiff concrete structure can more effectively exert the respective advantages of the section steel and the concrete, the defect that the steel structure is easy to partially buckle is overcome, the ductility of the structure and the member is increased, and the brittle characteristic which is not beneficial to earthquake resistance and is caused by the poor ductility of the high-strength concrete is improved; in addition, compared with a reinforced concrete structure, the reinforced concrete structure effectively reduces the section size of the member, increases the use space, reduces the beam column section, adjusts the axial compression ratio and improves the bearing capacity of the structure; compared with a steel structure, the steel structure has the advantages that the steel consumption is saved, the manufacturing cost is reduced, and the fireproof and anti-corrosion performances are improved.
The following is the construction steps of the utility model discloses the tie-beam of main building and skirt room do the concrete description:
and hoisting and installing the steel column of the rigid column of the main building and the steel column of the rigid column of the skirt house, and erecting an outer frame.
The span of the connecting beam between the main building and the skirt house is large (the span of partial beam exceeds 14m), and the hoisting of the stiff column of the main building is inconvenient according to the setting principle of the conventional construction joint at the position of 1/3, so that only a bracket with the length of 1.2m is arranged on the stiff column of the main building.
And a plurality of sleeves are welded on the flanges of the stiff steel columns of the main building and are used for connecting longitudinal main reinforcements of the steel reinforcement framework. And main ribs of the steel reinforcement framework are connected on flanges of the stiffness steel column of the skirt house by adopting rib plates, wherein the width of the rib plates is the same as that of the section steel, and the length of the rib plates is 10d for single-side welding or 5d for double-side welding.
When the construction joint is kept somewhere in the main building construction stage, the reserved longitudinal bottom rib below the orthographic projection section of the steel beam is 100mm shorter than the bracket, and the main ribs in other positions are adjacently staggered for one lap joint length for reservation and are shortest to be not less than 1200mm, so that the operation is facilitated. And protecting all the reserved main reinforcement mantle fibers by using a protective cap. And after the main building stiff column is poured and demoulded, chiseling and cleaning the construction joint.
When the skirt building is constructed, in order to avoid the influence of the main building outer frame, the section steel is firstly hoisted to the plate surface, then the section steel is hoisted and positioned from the plate surface to the lower part and the upper part, and the section steel is welded and fixed after being in place.
For facilitating the operation of workers, the skirt house beam slab formwork support frame is erected by adopting a quick-dismantling frame, a step frame body is reserved at the beam bottom, the beam bottom die is not installed temporarily, and a springboard is laid simultaneously to serve as an operation platform for binding beam bottom ribs by workers. And meanwhile, when a bottom die of the floor slab is laid, the width of 1m is reserved on one side of the stiff beam to be used as a beam bottom rib mounting opening, so that beam bottom ribs can be bound conveniently.
Installing the stiff beam gluten and sleeving all stirrups, temporarily not positioning and binding the stirrups, and welding the main tendon at one side of the skirt house on the reinforcing plate. And erecting the main reinforcement and the stirrup at the bottom of the gluten every 1m by adopting a steel pipe so as to facilitate the penetration of the bottom reinforcement.
And (3) mounting the beam waist ribs and the beam bottom ribs, penetrating all the waist ribs and the longitudinal bottom ribs, positioning all the stirrups according to the designed intervals, and binding. Wherein, vertical end muscle divide into two sections, and the first section is installed one side of leaning on the main building straight threaded connection earlier, and the second section is connected to the reuse positive and negative silk sleeve. The tail end of the second section is connected to the rib plate of the rigid column of the skirt house. And bending the end parts of all the waist ribs, and welding the bent sections on the steel beams. And after all the waist ribs and the bottom ribs are installed, the distance between the stirrups is adjusted, and finally the stirrups are bound.
And after the steel bars are bound, dismantling the springboard of the beam bottom operation platform, supplementing the rest one-step supporting frame, inserting the adjustable U support, installing the beam bottom die and the back ridge in place, and integrally adjusting the adjustable U support to the designed elevation.
And (4) installing the side die of the connecting beam and the reserved floor slab bottom template, and pouring concrete in the space enclosed by the templates after binding the slab ribs to finish construction.
The utility model discloses the beneficial effect of the tie-beam of main building and skirt room does:
the utility model discloses a set up first bracket and second bracket and connect shaped steel and concreting, form to connect the tie beam who is fixed in main building strength nature post and skirt building strength nature post, included the advantage of concrete and shaped steel simultaneously, solved among the prior art distance between main building and the skirt room in order to guarantee sufficient bearing capacity when too big, the great occupation space of cross sectional dimension of concrete structure roof beam is too big, influences the problem of the construction of other structures.
