Abstract
The utility model relates to a plug-in floor steel secondary beam node structure which comprises framework concrete beams and floor steel secondary beams; and the plug-in floor steel secondary beam node structure is characterized in that the floor steel secondary beams are spliced into the framework concrete beams. The utility model has the advantages that the serving time of the framework concrete beams is saved, thereby greatly improving the construction progress; the factory space is increased, thereby facilitating the arrangement of the process pipeline equipment; and the lifting lugs or embedded parts for the framework concrete beams are eliminated, therefore, the plug-in floor steel secondary beam node structure is better in economical efficiency and more beautiful in appearance.
Description
Technical field
The utility model belongs to thermal power generation power plant civil engineering structure design field, especially relates to a kind of combination flooring plug-in type steel secondary beam node structure.
Background technology
Because process pipe and equipment are more, and load is bigger, and it is reinforced concrete frame that the main building structure adopts main frame mostly, each floor face adopts girder steel to cast board combining structure in the main building of steam power station.Each floor face steel secondary beam is connected with the concrete frame concrete beam and all adopts pure being articulated and connected, way has two kinds of ways usually: a kind of mode is that the steel secondary beam directly is bearing in the girder side and chooses on the ear, another kind of mode is to reserve embedded part in the girder side, steel secondary beam and the welding of girder side embedded part.
First kind directly is bearing in the connected mode advantage of choosing on the ear is stressed comparatively clear and definite, owing to use for many years on the main building flooring of steam power station, technology is ripe, and related specifications and handbook all have theoretical the support; Shortcoming is that the installation of flooring steel secondary beam must be waited until after the main frame concrete reaches design strength and just can carry out, and takes 28 days usually and the main frame concrete reaches design strength, has influenced construction period greatly; Because floor load is bigger, and it is also very big usually to choose ear, and the girder side is chosen ear and taken the factory building space, influences process pipe and arrange in addition, and uneconomical, not attractive in appearance.
The form of second kind of steel secondary beam and the welding of girder side embedded part is same, and technology is comparative maturity also owing to use for many years on the main building flooring of steam power station, and related specifications and handbook all have theoretical the support; Its shortcoming is that the installation of flooring steel secondary beam must be waited until after the main frame concrete reaches design strength and just can carry out equally, the construction period lengthening; Beam side embedded part is more and bigger in addition, and construction blanking difficulty is relatively large.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly saves construction period, guarantees structural safety, reduces the factory building space, overall cost is low, the combination flooring plug-in type steel secondary beam joint structure of good looking appearance.
For solving the problems of the technologies described above, the utility model provides a kind of plug-in type flooring steel secondary beam node structure, comprises frame concrete beam, flooring steel secondary beam, and it is characterized in that: flooring steel secondary beam is plugged in the frame concrete beam.
Flooring steel time web has preformed hole, and the vertical muscle of the framework in the frame concrete beam passes the preformed hole on the flooring steel time web.
In order to satisfy the die-cut requirement of flooring steel secondary beam, be provided with below the flooring steel secondary beam in the frame concrete beam and hang muscle.
In order to satisfy flooring steel secondary beam anchoring requirement, according to flooring steel secondary beam and upper load size, flooring steel time beam end is provided with dowel.
The utility model advantage is to have saved frame concrete beam conditioned time, accelerating construction progress greatly; Increase the factory building space, helped the process pipe apparatus arrangement; Save the frame concrete beam and chosen ear or embedded part, better economy, profile is better appearance also.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view along A-A line among Fig. 1.
The specific embodiment
With reference to Fig. 1,2, frame concrete beam 1 is the cast-in-situ steel reinforced concrete beam, and floor plate 3 is cast-in-situ steel reinforced concrete floorings, and flooring steel secondary beam 2 is a H shaped steel, and flooring steel secondary beam directly inserts in the frame concrete beam, near midline position; Flooring steel time web has preformed hole, the preformed hole that the vertical muscle 4 of frame concrete beam inner frame passes flooring steel time web does not weld with flooring steel secondary beam, in flooring steel secondary beam underframe concrete beam, be provided with and hang muscle 6 and satisfy the die-cut requirement of flooring steel secondary beam, flooring steel time beam end is provided with dowel 5 according to itself and upper load size, satisfies flooring steel secondary beam anchoring requirement.
During building operations, before the frame concrete beam was not built, flooring steel secondary beam directly inserted and forms effective node in the frame concrete beam, treat flooring steel secondary beam installation in position after, re-lay the flooring reinforcing bar, last pouring frame concrete beam and floorslab concrete.
