Description
Technical field
The present invention relates to a kind of part outsourcing combination beam, in particular to a kind of resistant slide part outsourcing combination beam and its prefabricated
Method.
Background technique
For traditional transfer structure for SRC beams, when beam is acted on by sagging moment, beam lower part concrete in tension cracking.
The concrete of cracking exits work, and contribution function cannot be not only played to the bearing capacity of beam, also will increase the self weight of component,
Increase project cost.Thus, just remove this part of concrete when pouring component, can not only reduce the waste of material, also
The burden of vertical member can be mitigated, reduce project cost.
There are problems that the bond slip between fashioned iron and concrete for traditional part outsourcing combination beam.When fashioned iron and mix
After Cementation failure occurs between solidifying soil, component no longer meets plane cross-section assumption, and bearing capacity is by very big weakening, and material is no longer
Its strength character can be given full play to.In addition, bond-slip can cause the reduction of specimen stiffness.
For transformation reinforcing project and modern architecture, building interior always has many pipelines, particularly with mechanical floor and
Basement.The pipeline of these pipelines is frequently necessary to across beam.This just needs to perforate on beam, this will lead to reinforcing bar quilt in beam
It interrupts, and the rigidity of beam, bearing capacity will greatly be weakened.
Summary of the invention
Goal of the invention: the invention discloses a kind of resistant slide part outsourcing combination beam and its method for prefabricating, the resistant slide portions
Exceptionally packet combination beam self weight is lighter, and concrete and steel pipe interact, and can play the role of anti stick sliding；The method for prefabricating
The resistant slide part outsourcing combination Liangqi duration of production is shorter, and efficiency is higher altogether.
Technical solution: a kind of resistant slide part outsourcing combination beam, including channel steel, the steel plate with hole, square steel tube, interior filling
Concrete, end steel plate；Wherein the upper and lower two sides of the steel plate with hole are weldingly connected with a channel steel respectively, and square steel tube passes through band
The hole of the steel plate of hole, and be welded on hole, channel steel both ends are welded with end steel plate；Channel steel, the steel plate with hole, square steel
Fill concrete in the steel skeleton for the beam that pipe is formed with end steel plate.
The hole of steel plate with hole fits with square steel tube outer surface.Hole interval on steel plate with hole is uniformly divided
Cloth, the hole of the steel plate with hole are honeycombed or rectangle, and square steel tube is the hexagon steel pipe or rectangular steel pipe of honeycombed.Square steel
The overall width of pipe is equal to the overall width of channel steel.So that smooth side is integrally formed after concreting.
The channel steel of the upper and lower two sides connection of steel plate with hole is symmetrical arranged about the steel plate with hole, and the steel with hole
Two sides are located at the groove middle position of channel steel above and below plate.
The invention also discloses a kind of method for prefabricating of resistant slide part outsourcing combination beam, specifically comprise the following steps:
Step 1) opens up hole on the steel plate, matched square steel tube is passed through hole, and be welded to connect with hole；
Step 2) welds the steel plate with hole and channel steel and square steel tube, forms the steel skeleton of beam, by reinforcing bar
Frame and end steel plate weld；
Component side is turned to upwards, and pours coagulation by step 3)；
Step 4), etc. after concrete have early strength, another side is turned over upwards, another surface concrete is poured；
Step 5) conserves component to specified age according to code requirement；
Component is transported to in-site installation by step 6).
The utility model has the advantages that a kind of resistant slide part outsourcing combination beam disclosed by the invention, has the advantage that
1, be equivalent to traditional transfer structure for SRC beams because having lacked the concrete on the outside of fashioned iron, component from
Beijing South Maxpower Technology Co. Ltd is reduced；
2, cellular hole is opened in web, and welds hexagon steel pipe on hole, and concrete and steel pipe interact, can
To play the role of anti stick sliding, guarantee that fashioned iron and concrete work together；
3, hollow steel pipe can allow pipeline to pass through, and not need to drill on beam in reinforcing or design, facilitate design and apply
Work；
4, component may be implemented prefabricated, and beam end is smooth, can weld together with steel column after end plate is burn-on in end；
5, concrete can be constrained in the rib of channel steel, so that concrete is increased the intensity and change of concrete by multidirectional constraint
Shape ability；
6, component does not need formwork supporting plate in casting process, can effectively shorten duration and project cost；
7, square steel tube can be used as the channel of pipeline, not need again in beam opening.
