Description

Stirrup cage structure in beam column core area

Technical Field

The utility model relates to a beam column node structure in the building specifically is a beam column core space stirrup cage structure.

Background

The most common frame beam column construction method in engineering practice has two types: one method is to bind stirrups of each layer of column including a column body, an encryption area and a node area all at once according to requirements, then install a column template, leave construction joints 5-10 cm below a beam bottom for pouring column concrete, then install a column head node template and a beam bottom template (or including a beam side template) after a column side template is detached, and then bind frame beam reinforcements. The joint stirrups influence the pouring operation of the column concrete, and a concrete worker often has to untie the binding wires and knock the bound joint stirrups from the side to open a large opening so that the concrete flows into the column more smoothly. Thus, the stirrups in the node area are disturbed, and the original shape is not easy to restore, and the labor and the time are increased. When the column concrete is poured, part of the reinforcing steel bars can be polluted by cement paste, and the bonding of the reinforcing steel bars and the concrete is influenced. In addition, it is troublesome to thread the beam bottom rib after the joint area stirrup is tied up, and especially, it is difficult to thread the bottom rib with a hook (such as an edge support). At the moment, a steel bar worker has to beat the tied joint stirrup and even blows the hook without permission to cause insufficient anchoring of the longitudinal bar.

The other method is to use a so-called 'beam sinking method' to bind frame beam reinforcements, namely, leave the stirrups in the node area not bound when binding the column hoops, and after the node templates, the beam templates and the floor slab bottom moulds are installed by carpenters, bind the beam reinforcements on the floor, and remove the temporary supports after binding so as to drop the beam reinforcement frameworks into the beam moulds. The method is easy to miss column hoops in the node area, and the column hoops are often not bound, are insufficient in quantity, are not separated in space and are difficult to adjust.

Among the prior art, patent publication No. CN208009635U discloses a frame construction beam column node prefabricated stirrup cage of setting up fixed muscle of U type, and among this technical scheme, the nuclear core district stirrup of constituteing by a plurality of parallel arrangement's rectangle node positioning steel bar is introduced to fixed muscle of U type through both sides has constituteed prefabricated stirrup cage jointly, still is equipped with the assistance-localization real-time muscle of cross arrangement in stirrup cage two other sides. However, in practice, it is found that the use of U-shaped fixing ribs and cross-arranged auxiliary positioning ribs is inconvenient, time and labor are wasted in installation and removal, and the positioning accuracy is not high.

Disclosure of Invention

The utility model discloses a solve and improve beam column core region node stirrup construction quality for construction speed scheduling problem provides a beam column core region stirrup cage structure.

Realize the technical scheme of the utility model, a beam column core space stirrup cage structure, including cross arrangement's beam template and post template, be equipped with beam reinforcement and beam stirrup in the beam template, be equipped with vertical post reinforcing bar and post stirrup in the post template, be equipped with the stirrup cage at beam reinforcement and post reinforcing bar cross node, the stirrup cage include a plurality of parallel arrangement's node stirrup, the node stirrup entangles all post reinforcing bars, the node stirrup between fix through the locator card, the locator card include the locating lever, set up a plurality of spacing cards on the locating lever, beam reinforcing bar level pass the stirrup cage.

Through the design that sets up the stirrup cage in intersect department to set up the locating lever on the stirrup cage, can improve beam column core region node stirrup construction quality, accelerate construction speed.

To sum up, compare with prior art, the utility model discloses technical characterstic:

the method has the advantages that firstly, the installation quality of the column hooping at the node of the beam column is obviously improved through the use of the positioning card;

secondly, after the whole beam steel bar falls into the template, the position, the spacing and the like of the column stirrups at the joints do not need to be adjusted again, so that the labor and the time are saved;

the construction operation process is simple, the operation personnel can easily accept the operation process, and the construction efficiency is greatly improved;

the manufacturing mold of the stirrup limit card is simple to manufacture and has strong practicability and universality; (can be used in a turnover way, and the limit card can be taken out after being put in place, so that materials are not wasted);

fifthly, when the cross section of the beam and the reinforcing bars in the core area are large, the column reinforcing bars can deviate in one direction after the construction of the beam reinforcing bars is finished, and the spacing distance between the frame column stirrups can be fixed and the thickness of four protective layers of the frame column reinforcing bars can be fixed to be uniform by utilizing the limiting clamp;

when the section of the beam in the core area is large and the beam reinforcement is large, the contact surface of the limiting clamp and the stirrup is large, so that the column stirrup can be ensured to be distorted and deformed due to uneven stress;

the number of the limiting steel bars is small, and the construction of the beam steel bars is not influenced at the position where the steel bars are dense in the core area;

when the cross section of the beam is larger and even the size of the cross section of the column is the same, the limiting steel bars are more flexible and simpler to place than the U-shaped positioning bars;

and ninthly, the limiting clamp can be machined on the construction site according to the actual conditions of each project, construction is convenient, and machining cost is low.
