It connects, there may be hydrogen for the high temperature during reinforcement welding, and are dissolved in liquid metals, enter inside postwelding steel, shape
It even cracks at Microamounts of Hydrogen internal residual, or can lead to material embrittlement outside plus under stress, this defect is exactly hydrogen embrittlement, then
Post weld heat treatment is needed to carry out the hydrogen that disappears of pad, removal welding stress and the comprehensive mechanical performance for improving pad, is mentioned
High-ductility prevents brittle fracture.
The solder joint heat treatment mode of existing reinforcing bar has welding machine electrified regulation method, flexible ceramic electric heater heating, fire
Flame heating.These methods can quickly heat solder joint and reach the temperature that heat treatment needs, but energy consumption is high, and there is touching
Electricity, the security risks such as fire.
Pad disappear hydrogen heat treatment, refer to welding complete after, when weld seam is not yet cooled to 100 DEG C or less, progress
Low Temperature Heat Treatment.General norm is to be heated to 200~350 DEG C, keeps the temperature 2-6 hours.After post weld heat treatment, the gold of connector
Phase constitution is improved, and plasticity, the toughness of welding point is improved, so as to improve the comprehensive mechanical performance of welding point.
Utility model content
There is hydrogen attack, in this way meeting in pad due to inappropriate technology or wlding dampness etc. when for traditional reinforcement welding
The mechanical performance for substantially reducing solder joint, will appear hydrogen embrittlement fracture when serious.Present reinforcement welding does not have dehydrogenation work substantially
Skill, it is desirable that in the case where carrying out dehydrogenation heat treatment, dehydrogenation is generally carried out using flame heating or resistor ceramic heating pad
Heat treatment, however the construction of these methods is complex, preparation is also relatively complicated, and there are some potential safety problemss.For
We need a kind of simple quick and highly-safe steel bar welding contact dehydrogenation device for this.
In order to reach above-mentioned purpose of design, the technical solution adopted in the utility model is as follows:
Chemical heat-generating agent packet is arranged including hollow insulated bag in a kind of building iron dehydrogenation device in insulated bag, chemistry is raw
Thermit powder packet includes heat generating agent packet one and heat generating agent packet two, and heat generating agent packet one has communication port A, and heat generating agent packet two has communication port B,
Communication port A is connected with communication port B by sealing strip, and sealing strip is sealingly disposed on communication port A and communication port B.
Insulated bag includes outer layer and internal layer, and outer layer connect to form hollow structure with internal layer, and outer layer is asbestos insulating layer, internal layer
For high heat conduction layer,
Internal layer is aluminium alloy lamella.The internal layer is directly contacted with reinforcing bar.
Internal layer is with a thickness of 0.5-2 millimeters.
Rope is provided on sealing strip, rope is pierced by insulated bag.
Sealing strip is tightly connected by bonding and communication port A and communication port B.
Magnet is arranged in insulated bag internal layer inside edge.
The utility model has the advantages that
Heat generating agent packet is housed, the heat generating agent packet A and heat generating agent packet B are two independent reaction packets, are stored up respectively in insulated bag
Hide after hybrid reaction can heat production reactant, two Bao Douyou communication ports seal up by sealing strip, when needing to carry out chemical heat generating
When reaction, sealing strip is removed, two heat generating agent packet connections, heat generating agent hybrid reaction generates amount of heat, by insulated bag
It is coated on steel bar welding contact, heat preservationization butt welding contact is heat-treated, and 2~6 hours is kept the temperature, to achieve the purpose that dehydrogenation.
Two layers of formation hollow structure of insulated bag, heat generating agent packet are placed in hollow structure, and the outer layer of insulated bag is that asbestos are protected
Warm layer can guarantee that heat loss is less, and inside is High heat conduction material layer, can conduct heat to the steel bar welding contacted
Contact.
Magnet, so quick, laborsaving, saving of labor when carrying out pad cladding is arranged in insulated bag internal layer edge.
There is rope across insulated bag on sealing strip, it is only necessary to can just sealing strip be made to open marline pulling, it is more convenient.This
Chemical heat-generating agent, and independent packaging are used in utility model；Absorption type asbestos bag edge is implanted into magnet, is convenient for clad welded
Point, it is simple and fast；When in use it is only necessary to drawstring is pulled down shake up tightly be attached at pad can butt welding contact into
Row heating and thermal insulation dehydrogenation.Using easy, quick, reliable, safety is higher.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the building iron dehydrogenation device of handy and safe.
