Description

Steel bar jacking type connecting member, application structure and construction method thereof

Technical Field

The invention relates to the technical field of civil engineering, in particular to a steel bar jacking type connecting member, an application structure thereof and a construction method thereof.

Background

The traditional steel bar connection site construction process comprises the following steps: welded connection, bar straight/tapered threaded connection, etc.

The traditional prestressed hollow floor slab has high loading capacity, but no connecting ribs, and has poor structural connection integrity and low shock resistance. The existing prefabricated concrete superimposed sheet needs to realize the connection of the reinforcing steel bars in a mode of site secondary binding of the reinforcing steel bars; the secondary binding of the steel bars and the concrete pouring wet operation on site generate wastewater and waste discharge, and the environmental protection is poor; the process is complex and the efficiency is low.

The connection of the prior prefabricated wallboard, beam and column members usually adopts a grouting connection mode of a reinforced sleeve, and has the defects of slurry leakage, clamping stagnation, influence by factors such as climate temperature, personnel operation and the like, poor quality controllability and inconvenient quality inspection.

The operation cost of prefabricating, transporting, hoisting, secondarily binding the steel bars and pouring concrete is high.

The steel bar sleeve is connected by grouting and anchoring, and the yield strength, the elongation and the bending resistance technical performance index of the steel bar are lost or lost.

The installation joint seam of the member and the floor is low in strength and easy to crack and leak, and then the member and the floor are connected in an anchoring manner to form a weak node, so that the requirement of earthquake-proof design of the strong node and the weak member is not met.

The secondary concrete pouring results in great self-weight (about 30% thickness is increased, namely the material consumption is increased), and the shock resistance is reduced.

The increase of the material consumption has poor energy conservation.

The concrete installation method comprises the following steps:

The first step: vertical component (wallboard/column) installation method: firstly, mounting a wallboard in place, and then mounting a diagonal bracing rod to adjust verticality and support and fix;

The problems are: the installation height and levelness of the component are difficult to adjust, the efficiency is low, the axis position is limited by the installation clearance between the connecting rib and the sleeve, the quality cannot be ensured, and the installation efficiency is low;

and a second step of: the bottom seam of the component is plugged by mortar; the existing problems are that the mortar is low in strength and easy to crack and leak, so that weak nodes are formed;

And a third step of: grouting material is filled in the steel bar sleeve for connection. The quality-controllable quality common problem of slurry leakage clamping stagnation exists under the influence of factors such as climate temperature, proportion, operation, service time and the like;

Fourthly, binding reinforcing steel bars of the cast-in-place concrete structure part; the assembly rate of the vertical components is low (within 60 percent), the efficiency is low, and the cost is high under the influence of the quality of the grouting connection process of the steel bar sleeve;

fifthly, installing a laminated slab support frame;

Sixthly, installing a template;

seventh, the method for installing the laminated plates comprises the following steps: after the installation of vertical components such as wallboards/columns, templates and laminated slab supporting frames is completed, installing laminated slabs;

Eighth step, steel bar and pipeline installation: after the installation of the superimposed sheet is completed, carrying out the operation of the pre-burying process of the steel bar binding pipeline;

Ninth, concrete is poured: pouring concrete on the integral large area of the laminated slab after the reinforcing steel bar procedure is finished, wherein the thickness of the cast-in-place concrete is larger than the prefabricated thickness (the prefabricated thickness is not lower than 6 cm and the cast-in-place thickness is not lower than 7 cm);

Tenth step, construction of a decorative layer: and (5) performing construction operations of the leveling layer, the bonding layer and the decorative layer after concrete pouring.

The problem with the superimposed sheet installation is: the vertical support frame needs to be installed for the second time, the template is needed to be installed at the edge of the laminated slab, and the mass controllability is poor due to the influence of factors such as weather, temperature and personnel in large-area concrete pouring operation, so that the efficiency is low, the cost is high, the dead weight is increased, and the shock resistance is reduced.

Therefore, how to provide a floor slab member and a construction method thereof to solve the above-mentioned difficulties is a problem that a person skilled in the art needs to solve.
