Abstract
The invention relates to a novel angle joint combined assembly method of a concrete prefabricated part, belonging to a combined assembly method of a concrete prefabricated part. In the invention, non-bonding prestressed tendons arranged in the concrete prefabricated parts are firmly connected together by a steel angular anchor backing plate and an anchoring tool, so that the concrete prefabricated parts can be connected at any angle. In the invention, the method makes full use of the angle formed between the tendon penetrating holes on the sides of the steel angular anchor backing plate, and the non-bonding prestressed tendons slide in the parts without bonding; and due to the tension locking property of the anchoring tool, the angle of the concrete prefabricated part pair is accurate, the building structure has high strength, and the combined assembly is fast.
Description
Technical field
The present invention relates to a kind of concrete prefabricated element combination assembly method.
Background technology
Be combined into various building structure with concrete prefabricated element, have the advantages that cost is low, speed is fast, easy to operate.But, due to combination method mainly concrete prefabricated element mutually overlap, prefabricated units built-in fitting is welded to each other, and prefabricated units bolt is interconnected.So its building structure combined strength is low, assembled dimension inaccuracy.In addition earthquake takes place frequently, more and more higher to the requirement of building structure, old concrete prefabricated element combination assembly method, the building structure requirement in inapplicable modern times.
Summary of the invention
The invention provides a kind of concrete prefabricated element and adopt corner connection combination assembling new method, to solve the problem doing the assembling of various angle combinations between existing concrete prefabricated element.
The present invention takes following technical scheme:
(1), unbonded prestressing tendon is set in concrete prefabricated element;
(2), angle anchor plate makes: make with angle and the anchor plate wearing muscle hole;
(3), by the unbonded prestressing tendon in each prefabricated units wear muscle hole through steel angle anchor plate, with the fastening presstressed reinforcing steel of ground tackle stretch-draw, make each concrete prefabricated element make certain angle each other and connect.
Concrete prefabricated element of the present invention is beam, post, wall, plate.
It is non-caked in concrete that technical scheme of the present invention makes full use of unbonded prestressing tendon, can slide.By very heavy stretch-draw, ground tackle is locked, and makes the unbonded prestressing tendon of concrete component produce powerful tensile stress.Reaction force that this power produces, acts on interface and the prefabricated units itself of prefabricated units combination assembling, makes it bear compressive stress.This power meets the stressed principle that concrete anti-compression is greater than tension.By ground tackle and very heavy accurate stretch-draw locking, can reach concrete prefabricated element combination fitted position accurate, error free, the intensity of its building structure combination assembling is high.
The present invention has abandoned concrete prefabricated element in the past and has relied on built-in fitting welding, and bolton and prefabricated units to overlap the backward technique waiting combination assembling mutually, but assemble concrete prefabricated element with corner connection Combination of Methods.

Below 4 concrete prefabricated element corner connections are illustrated the present embodiment together:
1, first the unbonded prestressing tendon 6 at concrete prefabricated element 1 two ends is installed the bilateral angle anchor plate 5 of steel shown in two pieces of Fig. 2 and Fig. 6 ground tackle 7, stretch-draw is fastening;
2, two pieces of angle anchor plate correspondences that the unbonded prestressing tendon of Fig. 1 concrete prefabricated element 2, concrete prefabricated 4 respective one end is worn on concrete prefabricated element 1 are worn muscle hole;
3, concrete prefabricated element 2, concrete prefabricated element 4 are worn the unbonded prestressing tendon termination installation ground tackle that concrete prefabricated element 1 angle anchor plate correspondence wears muscle hole;
4, adopt operating procedure 1 method to install two pieces of angle anchor plates and ground tackle at concrete prefabricated element 3 two ends, stretch-draw is fastened to design stress;
5, the correspondence of concrete prefabricated element 3 liang of angle anchor plates is worn muscle hole and wear unbonded prestressing tendon corresponding to concrete prefabricated element 2, concrete prefabricated element 4, ground tackle is installed;
6, the ground tackle on the fastening concrete prefabricated element 2 of stretch-draw, concrete prefabricated element 4 two ends angle anchor plate is to design stress; Four Component compositions are assembled together;
7, concrete shutoff angle anchor plate and ground tackle.
As Fig. 5 be three prefabricated units with steel three corner to anchor plate corner connection schematic diagram.
1, the unbonded prestressing tendon 4 ' of concrete prefabricated element 1 ' is worn steel three corner to wear muscle hole ground tackle 6 ' to anchor plate 5 ' correspondence and fix, stretch-draw is fastened to design stress;
2, adopt same procedure concrete prefabricated element 2 ', concrete prefabricated element 3 ' to be worn on angle anchor plate other two and wear muscle hole, it is fastening to install ground tackle stretch-draw, and three Component compositions are assembled together.
