What should I do if the girder is broken while renovating the house?

First of all, the broken steel bar, especially the main bar, should expose 15 times the length of the diameter of the steel bar, and lap weld it with the same type of steel bar, note that it is double-sided welding. Small steel bars should also be treated in this way, if the conditions do not allow, small steel bars are tied with the method of binding, and the transverse steel bars should also be properly connected and tied. It is strictly forbidden to directly butt the main reinforcement, if the butt, a slightly accommodating way is to weld it on both sides with the same type of steel bar after docking, and the welding length can not be too short, because there is stress at the welding.

A simple way to deal with stress is to bake it with fire welding and then slowly cool it. The pouring concrete grade should be higher than 600, and the cement ratio should be increased appropriately. Before pouring, the old beam part should be fully moistened with water and drenched several times.

The curing period must reach 21 days before it can be, and the standard is 28 days to reach no intensity, because it is considered summer. So it can be early. After all, it's your own home, and safety is important.

It is necessary to standardize construction. If conditions permit, a steel beam should also be erected at the lower part of this beam, and the length should exceed one-third or one-quarter of the length of the fracture opening. The cross-sectional width of the steel beam should be less than the thickness of the current beam, and the short thin steel bar should be welded appropriately, and the bottom surface is also treated in this way, in order to paint the mortar concrete and lime paste in the next step.

Otherwise, the decoration is not good-looking, and there will be rust after a long time.

To achieve rust removal of steel, try to use cement mortar to paint first, and more cement, so that the rust will not fall off the stucco surface just now. If you live by yourself, safety is the top priority, pay attention to the process.

The method of directly adding steel beams and steel columns is not advisable, only non-load-bearing beams can be like this, and high-rise buildings are mostly weighed.

If it breaksStirrupsand structural steel bars, and the number is not large, just weld them, and finally fill them with mortar with high strength. But if it isLongitudinally stressed reinforcementThen it is recommended to calculate the remaining bearing capacity and then consider whether to reinforce.

The Chinese style is relatively free, and the decorations can be green plants, fabrics, and decorative paintings.

and different styles of lamps, etc. These ornaments can come in a variety of styles, but the main ornament in the space is a Chinese painting.

Lanterns. and traditional ornaments such as purple sand pottery. These decorations are not numerous, but they can be the finishing touch in the space.

Walk at the forefront of fashion:

Contemporary style. Decorative features: composed of curved and asymmetrical lines, such as flower stalks, flower buds, grapevines, insect wings and various graceful and wavy shapes and patterns in nature, etc., which are reflected in walls, railings, and window lattices.

and furniture and other decorations.

Some of the lines are soft and elegant, some are strong and rhythmic, and the whole three-dimensional form is integrated with the orderly and rhythmic curves. A large number of iron components are used, and new processes such as glass and ceramic tiles, as well as wrought iron products and pottery products are comprehensively used in the interior. Pay attention to the communication between indoor and outdoor, and strive to introduce new ideas to the interior decorative arts.

It is recommended to find a professional team to reinforce it, and add a lintel or something at the upper end of the door.

If it doesn't collapse immediately, the house won't be able to live in. The design carried out by the formal design unit, even if there is a surplus in strength, will not be so large that the two main reinforcements are still safe. The next development trend is generally the increase of deflection (collapse), the development and gradual increase of beam cracks, the withdrawal of concrete from work, the increase of reinforcement stress, the yield elongation under the action of tensile stress, and the gradual arrival of ultimate strength, necking, reduction of steel bar section, fracture, roof collapse, and even the possibility of damaging the wall or floor slab below or adjacent to the room.

Involving the intervention of neighbors, property management or quality control can have serious consequences.

Solution, 1. If the floor height is about 3 meters, immediately use a log column with a diameter of 120 mm or a steel pipe with a diameter of 100 mm, and support the roof at a distance of each meter (a backing plate should be added to the top and bottom, and a horizontal and diagonal brace should be added between the top columns to maintain stability); Then invite professional design and construction personnel to come to the site to reinforce the beam according to the damage situation. A safe and convenient way to do this is to bond steel bars or plates at the bottom or side of the beam. This requires a professional construction team to carry out the construction.

The height of the floor should be larger, and the diameter of the top column should be increased. Closely observe the changes of the beam before supporting the roof, and if the waist collapses severely, remove the roof waterproof insulation layer according to the situation, or simply evacuate (notify the neighbors). Safety first, life first.

2. Another method is to first support the beam according to the above method, and then dismantle and redo the beam and the concrete slab supported on it.

You can choose according to your own situation, but it should be fast, especially the top of the support should be done immediately. Roofing is an extremely important measure to maintain the safety of buildings and personnel, and it is recommended to find a person who understands it to supervise and guide on site.

Definitely not, this aspect has been taken into account when the house is designed, and the steel bars of the house are not stressed at one point, but also at each point.

Kiss. Hello! This is absolutely not a no-no.

The beams belong to the load-bearing structure, and the concrete protective layer of the reinforced concrete is only 2centimeters, knocking off a centimeter will not cause much damage, knocking off a few centimeters will damage the steel bar, which is absolutely not okay, if you do this, there will be serious safety hazards.

Hello, when decorating the toilet, you need to lower the beam surface by five centimeters, but there is no steel bar, will this affect the quality?

The beam is 30 centimeters deep and 60 centimeters deep, if the beam surface is five centimeters lower, it will affect the quality. Hello! You can do this in a different way. Why do you want to move the beams, dear. Personally, I recommend not moving the girders. This is meant to be a supportive role.

Isn't it that all the beams are lowered by five centimeters, but that the drainage pipes are lowered by five centimeters in some places, which affects the quality.

Kiss. This one can be scored 3 cm.

Kiss. This is no more than 5 cm and does not affect the quality problem.

During the decoration process, the load-bearing beam was destroyed, and only the formwork was installed and the concrete was re-watered.

1.During the decoration process, the load-bearing beam was broken and damaged, and only the template was installed and the concrete was re-watered. 2.

Re-erect the formwork, mix the concrete with expanded cement, the concrete strength grade is best above C30, first clean up the damaged concrete edge, brush Xinchang with plain cement slurry, and pour concrete.

There shouldn't be beams on the kitchen floor, right? It should have beams on the "top surface" - if that's the case, you can hide it with a suspended ceiling. The space between the kitchens is generally relatively small, and it is normal for the ceiling to be lower.

In addition, if the position of the beam is appropriate, the beam can also be covered in the form of a modeling ceiling.

The simplest way, according to the height and width of the ceiling when the ceiling is carried out, the beam is effectively hidden, made in the ceiling, not exposed to become a part of the ceiling, so that the beam is hidden and the top surface is modified, to achieve the beautiful and overall effect, only the effect of the ceiling drop, out of the sense of hierarchy and then auxiliary built-in lamp, the effect of the spotlight is better, so that the whole space is full of interest.

If the space beam is more and the depth is higher, should not be hidden, will create the effect of the lower ceiling of the space suppression, according to its original form, according to the situation, auxiliary lighting and the construction of false beams make the top surface staggered, the original beam and the false beam set off each other, enrich the top surface modeling, can also produce another decorative effect.

The use of translucent materials for packaging, not so heavy, the top light or wallpaper and special materials decoration, look unified and transparent, original, combined with the wall and ground, the style is unified, so that the space integration is also a good choice.

Summary. The house that has just been repaired for two years has not been renovated, and the wall on the beam is broken, and under normal circumstances, cracks appear in the wall above the beam on the second floor, which is a very serious problem, and it is likely that the foundation has collapsed, that is, the foundation was not compacted firmly. There is also a possibility that the beam cuts corners and uses less reinforced concrete.

It is recommended to knock off the surface bricks, redo the waterproofing, and apply the mortar again, which is easy to cause collapse. It is recommended to do reinforcement treatment. It can be used as an outrigger beam and fixed on a stable stressed beam and column.

Be careful not to put heavy objects on the balcony during use to reduce vibration.

The house that has just been repaired for two years has not been renovated, and the wall on the beam is broken, what is going on, under normal circumstances, there are cracks in the wall above the beam on the second floor, which is a very serious problem, and it is likely that the foundation has collapsed, that is, the foundation was not compacted firmly. There is also a possibility that the beam cuts corners and uses less reinforced concrete. It is recommended to knock off the surface bricks, redo the waterproofing, and wipe the mortar again, which is easy to cause the collapse of the fiber.

It is recommended to do reinforcement treatment. It can be used as an outrigger beam and fixed on a stable stressed beam and column. Be careful not to put heavy erection items on the balcony during use to reduce vibration.

There are small joints in the beams, and the upper walls are partitions between the window sills.

It can be used as an outrigger beam and fixed on a stable stressed beam and column.

1.I tell you very pertinently, you should hurry up to the "Housing Quality Appraisal Institute" to ask for expert appraisal. Every city has it. If you can't find it, you can go to the Department of Justice for advice.

2.Such an appraisal costs 3,000 RMB;

3.This practice is called "sticking steel", and it can be used when reinforcing it, but it is still not allowed to do so in decoration.

4.If the bonded steel is designed or made by a formal reinforcement company, there may be no structural problems. However, if the fire prevention treatment is not carried out, it is extremely dangerous to catch fire. Not only upstairs and downstairs, but the whole building may suffer.

5.The ideal construction of bonded steel is to be designed and calculated. The front decoration is done, and it is estimated that there is no design calculation. There is a certain danger.

6.To correct, the beams are all load-bearing. Beams are structural members that are not only load-bearing, but also subjected to horizontal loads and forces.

7.If the conclusion of the appraisal is dangerous, you can sue the original owner or the property management company. The court will order the defendant to restore or give you compensation.

Hello dear, during the decoration process, the load-bearing beam was destroyed, only the formwork was installed, and the concrete was re-watered. Re-erect the formwork, mix the concrete with expanded cement, the concrete strength grade is best above C30, first clean up the damaged concrete edge, brush it with plain cement slurry, and pour concrete.
