Background

The pillars with the shear span ratio less than 2 are called short pillars in building specifications, the short pillars are easy to generate shear failure when bearing horizontal shear force under high axial pressure ratio, the short pillars are brittle failure, compressed concrete is crushed under the action of composite stress during the failure, and tensile steel bars may not reach yield stress, and the short pillars are unfavorable for the overall earthquake resistance of the structure. At present, in order to improve the ductility of a frame short column, the modes of increasing the hooping ratio, improving the hooping form, increasing the concrete strength grade, increasing the longitudinal reinforcement ratio, adopting steel reinforced concrete and the like are generally adopted, wherein the hooping is usually encrypted along the full height of the column and is not suitable under the condition of higher axial compression ratio.

In addition, in the existing split column technology, gypsum boards or bamboo boards are mostly adopted as the separation materials, so that the cross section of the member is weakened to a certain degree, and the separation materials do not dissipate seismic energy. In addition, during the construction of the split column, the position of the longitudinal steel bar close to the separating material cannot be fixed, and the longitudinal steel bar can be closer to or even contact with the separating material, so that the thickness of a protective layer for pouring concrete at the position is reduced, and the durability of the concrete and the binding force between the steel bar and the concrete are affected.

SUMMERY OF THE UTILITY MODEL

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has:

1. spacing fixture block can all set up or the interval sets up on the stirrup on every layer, and the fixed position that closes on the longitudinal reinforcement of rubber partition board of spacing fixture block when concreting, ensures that the longitudinal reinforcement is whole to be pour the concrete in, reserves the protective layer of regulation, improves the durability of concrete, provides effectual adhesion to the reinforcing bar simultaneously, guarantees the combined action of reinforcing bar and concrete. The spacing flat plate is attached to the polytetrafluoroethylene plate on the surface of the rubber partition plate, so that when concrete is poured, the spacing fixture block cannot rotate on the stirrup, and the distance between the stirrup and the rubber partition plate is ensured.

2. The rubber partition plate is internally embedded with a plurality of layers of thin steel plates, so that the reduction of vertical bearing capacity caused by the separation of the rubber partition plate on the concrete section can be compensated, a layer of polytetrafluoroethylene plate with the thickness of 2 mm-3 mm is bonded at the contact part of the rubber partition plate and the concrete, the lower friction coefficient is realized between the polytetrafluoroethylene plate and the concrete, the rubber partition plate has better horizontal deformation energy, and if an earthquake occurs, the earthquake energy can be effectively absorbed under the earthquake action, and the brittle failure of the split concrete column is prevented.

3. Four inside vertical reinforcing bars in four concrete columns set up full-height and encrypt the stirrup, increase the distribution of reinforcement rate, prevent that the high axial compression ratio from lower the buckling of vertical muscle to evaginate.

4. Three rubber partition plates can be arranged, wherein one of the three rubber partition plates is the same as the width of the split concrete column, and the other two rubber partition plates are equal to half of the width of the split concrete column.

The utility model discloses a components of a whole that can function independently concrete column should still satisfy 6.3.7, 6.3.8, 6.3.9 regulations in "building antidetonation design rule" GB 50011-2010.
