Abstract
The invention relates to a new crossing and butting combined assembly method for concrete prefabricated members, and belongs to a combined assembly method for concrete prefabricated members. The method comprises the following steps of: crossing un-bonded prestressed ribs arranged in a concrete prefabricated member to reserved holes of the other concrete prefabricated member, and connecting and fastening the concrete prefabricated members together by using anchorage devices. By fully using the properties of sliding and non-bonding of the un-bonded prestressed ribs in the concrete prefabricated members and tensioning and locking of the anchorage devices, the concrete prefabricated members are combined and butted accurately, the combined and butted structure has high strength, and the combination and butting speed is high.
Description
Technical field
The invention belongs to a kind of combine and assemble method of concrete prefabricated element.
Background technology
Be combined into various building structure with concrete prefabricated element, have that cost is low, speed is fast, convenience operation.But because the method for combination mainly is that member overlaps each other, the member built-in fitting is welded to each other, and member interconnects with bolt.So, make its building structure combined strength low, combination size inaccuracy.Earthquake takes place frequently in addition, to building structure require increasingly high, so, old concrete prefabricated element combine and assemble method, the building structure requirement in inapplicable modern times.
Summary of the invention
The present invention provides a kind of concrete prefabricated element cross-under combine and assemble new method, and the combined strength that available coagulation soil prefabricated units combine and assemble method exists is low to solve, combination size inaccuracy, unhandy problem.The technical scheme that the present invention takes is:
(1), unbonded prestressing tendon is set in concrete prefabricated element;
(2), another concrete prefabricated element in combine and assemble is provided with preformed hole;
(3), the unbonded prestressing tendon of concrete prefabricated element is worn the preformed hole of another concrete prefabricated element, the unbonded prestressing tendon two ends are fastening with ground tackle stretch-draw, and its connection is tightened together.
Concrete prefabricated element of the present invention is beam, post, wall, plate.
The present invention gives full play to the concrete resistance to compression greater than tension, and unbonded prestressing tendon is non-caked can the slip in concrete, and very heavy, ground tackle stretch-draw connects the locking advantages of high strength.Through very heavy stretch-draw, ground tackle locking makes the unbonded prestressing tendon of combine and assemble concrete component produce powerful tensile stress.Prefabricated units combine and assemble interface and prefabricated units itself then all bear compressive stress, meet concrete stressed principle, and the intensity of its building structure combine and assemble is high.It is accurate, error free to reach concrete prefabricated element combine and assemble size through ground tackle and very heavy stretch-draw.
The present invention can keep the advantage that its cost is low, combine and assemble speed is fast, easy to operate, can improve its weakness again, makes its building structure combined strength high, and group and fitted position are accurate.
The present invention has abandoned the backward technology of concrete prefabricated element dependence built-in fitting welding and bolton combine and assemble.The building structure intensity of combine and assemble of the present invention is big, precision is high, and combine and assemble speed is fast, cost is low.And the building structure after the combination has high-intensity compressive pre-stress.
The present invention with dock, corner connection technology intersects and mixes can the derive new method of more combine and assemble concrete prefabricated elements of use.
Description of drawings
Fig. 1 is a concrete prefabricated element cross-under structural representation of the present invention.
Fig. 2 is a ground tackle structural representation of the present invention.
The specific embodiment
The technical scheme that the present invention takes is:
(1), unbonded prestressing tendon 201 is set in concrete prefabricated element 2;
(2), another concrete prefabricated element 1 in combine and assemble is provided with preformed hole 101;
(3), unbonded prestressing tendon one end of concrete prefabricated element 2 is installed ground tackle 1; The unbonded prestressing tendon other end of this concrete prefabricated element 2 is worn preformed hole 101 backs, the installation ground tackle 24 of concrete prefabricated element 2; Ground tackle one on the fastening concrete prefabricated element 2 of stretch-draw is to design stress, concrete prefabricated element 1 is connected with concrete prefabricated element 2 tighten together; With the preformed hole on the concrete blocking concrete prefabricated units 1.
Concrete prefabricated element of the present invention is beam, post, wall, plate.
The ground tackle 1 that the present invention adopts is identical with ground tackle 24 structures, specifically: place intermediate plate 302 in the anchor slab 301.
Claims (2)
1. a concrete prefabricated element cross-under combine and assemble new method is characterized in that comprising the following steps:
(1), unbonded prestressing tendon is set in concrete prefabricated element;
(2), another concrete prefabricated element in combine and assemble is provided with preformed hole;
(3), the unbonded prestressing tendon of concrete prefabricated element is worn the preformed hole of another concrete prefabricated element, the unbonded prestressing tendon two ends are fastening with ground tackle stretch-draw, and its connection is tightened together.
2. a kind of concrete prefabricated element cross-under combine and assemble new method according to claim 1, it is characterized in that: concrete prefabricated element is beam, post, wall, plate.
