Abstract

The utility model provides a steel bar connection mode that assembled concrete frame nodal connection structure adopts straight screw sleeve (5) and grout sleeve (6) by beam column node area and makes up and a nodal connection structural style that mutually perpendicular direction depth of beam differentiation design forming. The utility model discloses a problem of arranging with connecting the difficulty of node core space beam column node area reinforcing bar be can effectively solve, industrial production and construction installation are fit for.

Description

A kind of assembly concrete frame joint syndeton
Technical field
The utility model relates to prefabricated concrete structure technical field, is a kind of assembled beam-column node connecting structure adopting straight screw sleeve and grout sleeve at assembly concrete framework and frame structure bean column node region.
Background technology
Prefabricated concrete structure is the concrete structure be assembled by reliable connected mode by precast unit.Wherein, when carrying out the connection of assembly concrete framework and frame structure, the quality of connection of assembled beam-column node point connection zone is the key ensureing such integrality performance of the structure and anti-seismic performance.When carrying out assembled beam-column node area and connecting, owing to there is a large amount of vertical muscle of beam column intersection in joint cores, the layout of this region reinforcing bar be connected more difficult, this also makes assembly concrete frame installation efficiency low, construction cost is high, normalizing operation cannot be realized, and concrete pouring quality is difficult to obtain Reliable guarantee.
Summary of the invention
The utility model has the advantage of and overcome existing assembled beam-column node area reinforcement placement and be connected the difficulty existed, in conjunction with existing code requirement, provide the assembled beam-column node connecting structure of a kind of highly versatile, structural safety, efficiency of construction is high, mixed economy cost is low employing straight screw sleeve and grout sleeve.
The technical solution adopted in the utility model is as follows:
Pre-buried straight screw sleeve (5) and grout sleeve (6) when precast beam I (3), precast beam II (4), precast beam III (8), precast beam IV (9) make; Precast beam I (3) and precast beam II (4) is positioned at axis of pitch direction, and precast beam III (8) and precast beam IV (9) is positioned at longitudinal axis direction; Prefabricated lower prop (1) side precast beam I (3) adopts straight screw sleeve (5) to be connected with the vertical muscle in precast beam III (8) bottom, prefabricated lower prop (1) opposite side precast beam II (4) adopts grout sleeve (6) to be connected with the vertical muscle in precast beam IV (9) bottom, finally connect straight screw sleeve (5) and grout sleeve (6) at node region by a connecting reinforcement reinforcing bar (7), complete at the bottom of the beam of bean column node bonding pad and indulge muscle connection; Between orthogonal precast beam: precast beam I (3) and precast beam II (4) and precast beam III (8) and precast beam IV (9), realize dodging on depth of section of longitudinal reinforcement at the bottom of the vertical direction beam of beam column node area by the design of precast beam depth of section differentiation.
The utility model grout sleeve used (6) is extended type grout sleeve, the length of its lengthening section is connecting reinforcement (7) mantle fiber segment length (must be screwed into the length in offside straight screw sleeve (5)), the difference in height alienation design of the bar connecting mode combined by adopting straight screw sleeve (5) and grout sleeve (6) in beam column node area and mutually perpendicular direction beam section, effectively can solve the layout of beam column node area, joint cores reinforcing bar and the problem being connected difficulty, and be applicable to suitability for industrialized production and construction and installation.The advantages such as it is high that the utility model has beam column node area installation effectiveness, and node area security performance is good, effectively can improve the construction and installation speed of the bean column node bonding pad of assembling frame structure and frame structure.
Accompanying drawing explanation
Fig. 1 is assembled beam-column node connecting structure schematic diagram (the higher direction of beam section height).
Fig. 2 is assembled beam-column node connecting structure schematic diagram (beam section height lower one to).
Fig. 3 assembled beam-column node connecting structure horizontal profile schematic diagram.
Accompanying drawing code name illustrates: the prefabricated lower prop of 1-, the prefabricated upper prop of 2-, 3-precast beam I, 4-precast beam II, 5-straight screw sleeve, 6-grout sleeve (extended type grout sleeve), 7-connecting reinforcement, 8-precast beam III, 9-precast beam IV.
Detailed description of the invention
Below in conjunction with accompanying drawing, an exemplary embodiment of the present utility model is described, enforcement of the present utility model is not limited thereto.
First should when precast beam I (3), precast beam II (4), precast beam III (8), precast beam IV (9) make at the pre-buried straight screw sleeve of beam end (5) and grout sleeve (6), after prefabricated lower prop (1) hoisted in position, to connect main erection sequence as follows for its node.
(1) after precast beam I (3) installation that precast beam depth of section is larger, connecting reinforcement (7) is not processed one end and insert in the pre-buried grout sleeve of precast main beam (6) that (mantle fiber process is done in connecting reinforcement one end, one end does not deal with), then precast beam II (4) is installed, afterwards connecting reinforcement (7) mantle fiber end is screwed in the pre-buried straight screw sleeve of precast beam (5), complete the installation of this direction precast beam I (3) and precast beam II (4).
(2) installation of vertical direction precast beam III (8) and precast beam IV (9) is completed in the same way.
After (3) two direction precast beams: precast beam I (3) and precast beam II (4), precast beam III (8) and precast beam IV (9) installation, carry out the grouting works of grout sleeve (6).
The utility model structure is novel, practical, has safe and reliable and that efficiency of construction is high technical characterstic and handling characteristics.
