What is the principle of balcony load bearing problem?

And we usually think of things like furniture as live loads, but in fact it is not necessarily the most conservative consideration in theory. Besides, I'm even more bored, if the position of the fish tank you add is no longer moved, and the water in the tank is kept at the same level for a long time, then this is basically a veritable constant load. Why do I want to be entangled in this problem, let's take a look at the frame beams around the balcony floor, we know that the frame beams should be considered seismic resistance, that is, when the load combination is not only the above two formulas, according to the load combination in the anti-regulation should be constant + live) + horizontal**, I don't consider the vertical ** and wind here.

Therefore, the dead load and the live load appear in the combination in the form of gravity load representative value, and it is obvious that the design value obtained by considering the load of the fish tank as the dead load is larger. In fact, there is the following description of the partition wall in the Dutch regulations on this issue. The self-weight of the fixed partition wall can be considered as a permanent load, and the self-weight of the partition wall that can be flexibly arranged should be considered as a variable load.

Analogy furniture: I think this fish tank should be included in the dead load. Because this fish tank is only 1 ton = 10kn, the design of the dead load input or live load input has little impact on the result. Here I would like to explain why the No. 3 live load should be considered.

As a designer, you can go to the site to see, often the roof of the underground garage will be used as a construction turnover platform during the construction process, such as as as a reinforcement room stacking steel materials, etc., although theoretically the design can be indicated in the drawings that this is not allowed, but sometimes due to the site conditions, it has to be done. In addition, when carrying out soil covering construction, the excavator may drive directly into the basement roof, which can be regarded as barbaric construction. The direct consequence of the above two types is the appearance of cracks in the roof concrete, which will cause water seepage in the future.

Therefore, in some projects, we need to tell the owner about some kind of unpredictable situation that may occur, in order to avoid rework in the future, it is recommended to take these situations into account at the beginning of the design, which may bring an increase in cost, but the cost is still smaller than that of waterproofing and repairing leaks in the later stage. <>

100 structural plate thickness, and then consider 150 decoration layer, the most conservative estimate, the decoration layer is also calculated according to the full paving concrete, the weight of the slab plus the decoration surface layer a total of tons per square meter. If the building is designed to be relatively recent and the new code is adopted, then the live load is 1,000 N.

per square meter, that is, tons per square meter. According to the combination of (constant + live), the total tons per square meter, that is, 11 thousand Ox per meter. Under such loads, the balcony slab is estimated according to the four sides of the simple support, and the maximum bending moment.

In the middle, about 1 8 times 11 times 1 squared, equal to kn·m. The building should be a relatively new commercial house, not a dilapidated old house. The balconies of this kind of commercial housing are generally 100 mm thick, and the reinforcement is generally 8 @ 200 double-layer two-way, and the developer who pays attention to it will use 8 @100 double-layer two-way in order to prevent waterproof and cracking.

The load-bearing design of the balcony is generally KN per square meter, and the load-bearing capacity of the balcony is about 200 kg per square meter. The end of the balcony is also allowed to carry 1kn per square meter.

The end of the balcony can also carry a concentrated load of 100 kg per linear meter.

However, the load-bearing weight of the balcony is not particularly fixed, it also has a lot to do with its own weight. However, in general, due to the different areas of each building, in order to easily express the load-bearing capacity of the building, it is expressed by "pressure" in engineering construction, that is: cattle (n) square meters; For the sake of convenience and understanding, kg (1kg=, about equal to 10n) is also used.

For example, the area of a balcony is 1m wide * 2m long = 2, assuming that its design bearing capacity is 150kg, then the balcony can bear 2 * 150 = 300kg.

The balcony load-bearing load design is generally (movable load) of 2kn square meters, that is, the balcony load-bearing capacity is about 200 kg per square meter; In addition, the end of the balcony is allowed to carry a load of 1 kn m, because this end of the balcony can also bear a concentrated live load of about 100 kg per linear meter.

The load-bearing range of the balcony is divided into two types: one is the weight of the balcony itself, including the weight of the balcony floor, upper and lower plastering, and railing; The second is the change of load-bearing after the balcony.

For a long time, the national implementation of the balcony load-bearing design standard is: 250 kg square meters, more than this standard will inevitably bring potential safety hazards. However, the weight of the balcony is not particularly fixed, it also has a lot to do with its own weight.

The balcony is the cantilever beam structure, the general balcony is mostly two meters, the general cantilever beam can be used as the structure load-bearing, from the perspective of use, the balcony has its particularity, such as stacking sundries, planting flowers and grass, etc., and now it is often put washing machines, treadmills, etc. Therefore, based on safety considerations, it is stipulated in the Code for Structural Loads of Buildings GB50009-2012 that when designing the structure of a dwelling, the live load of the balcony is larger than that of other parts of the dwelling.

Even so, it is still not advisable to concentrate heavy items on the balcony, and remember not to place heavy objects on the outside of the balcony or on the handrails.

What is the difference between a recessed balcony and a wall-mounted balcony? Today is a long time to see.

Generally, one square meter can withstand about 200 kilograms. Its load-bearing is usually divided into two categories, one is its own weight, the other is the weight it can increase, the national standard balcony load is about 250 kilograms per square meter, beyond this range there will be potential safety hazards.

Precautions for balcony decoration1. Balcony doors and windows should be waterproof.

First of all, waterproofing should be passed, if the waterproof quality is not good, when it rains, rainwater will infiltrate in, and the balcony will be damaged after a long time, affecting the service life of the building. In addition, this is not conducive to keeping the balcony clean and tidy, so when decorating, the gap between the bottom of the window and the ground should be filled with foaming agent, and then sealed with silicone, so that there will be no water seepage.

2. The balcony should protect the load-bearing side wall and cannot be modified at will.

Nowadays, many young people like to renovate the balcony, pay attention to the design plan should be done before the start of construction, its side wall can not be demolished, because it has the effect of windproof and load-bearing, it is very important, and it is easy to leave potential safety hazards after demolition.

The balcony load is generally judged according to the balcony live load, and according to the national building code, the balcony live load is generally, that is, no square meter can bear a maximum of 250 kg of weight; Referred to as live load, also known as variable load, is the use or occupation load and naturally occurring natural load caused by people, materials and vehicles applied to the structure.

Generally, it is about 200 kilograms, and if it is a suspended type, it is best to distribute the items evenly to disperse the weight of the balcony.

Generally, the weight of something very heavy is generally 3 to 4 tons.

If the structure (structure) is different depending on the actual situation, the weight that can be borne will be different.

In practice, the balcony will generally have a load-bearing limit, and if it exceeds this limit, it is very unsafe to stand on the balcony. How much is the load of the balcony? Let's talk to you and talk about it.

In general, ordinary balconies and designs can bear about 250 kilograms per square meter, so you must not put too heavy items in the process of use. You can't turn the balcony into a kitchen or bedroom, so there is no big safety hazard in normal use, and there is no need to worry too much. <>

Some balconies belong to the wall-supported type, which can directly connect the balcony with the wall, and this form of balcony is designed in the form of the second test for the balcony. The balcony with the beam type is stretched out on the wall with two beams, and the board of the balcony is directly placed on the beam, which is a very simple structure and is very simple, and the load-bearing on it is very dangerous. <>

Many homeowners usually turn their balconies into multi-purpose areas, and this is not a problem. However, there is a kind of balcony that is hung outside, and it cannot be changed into a bedroom, otherwise it will cause a great burden on the balcony and then there will be safety hazards. Some heavier pots are also best not placed in the farthest part of the balcony, but should be leaned in, otherwise it will cause the load weight of the balcony and affect the service life of the balcony.

When decorating, you must focus on safety and security, and don't have a fluke mentality, after all, in this society, the probability of safety accidents on the balcony is also very high. Especially for owners with children at home, you must be careful not to design the balcony as a place for children to play, and there will be a lot of accidents when children jump. If the balcony has a strong load-bearing capacity, it doesn't matter, but during the renovation period, it is recommended that you do not expect too much from the balcony.

The balcony is just a place to relax, don't have too many desires.

Generally, the load per square meter is about 250 kg, so the balcony can not let go of heavy items, so as not to cause safety hazards.

The balcony design live load (movable load) is 2kn square meters, that is, about 200 kg per square meter; In addition, the end of the balcony is allowed to carry a load of 1 kn meter, i.e. a concentrated live load of about 100 kg per linear meter at the end. The above is the design value, and the actual balcony varies according to its design safety margin, construction and material quality. The balcony is a cantilever component, the position of the steel bar is very strict, if the upper steel bar is accidentally stepped down during construction, the bearing capacity of the balcony will be greatly reduced, and even collapse, and this kind of thing is often there in varying degrees.

Therefore, it is necessary to avoid its full load in use, especially not to put more things at the end of the balcony.

At this time, it is related to the decoration material of the balcony, which generally cannot exceed 250 kg, which is also the relevant national standard.

It's about 250 kilograms, which is a national standard, so that it can better protect the safety of some people.

Generally, it is 250 kilograms, which is a national standard, but it depends on the size of your balcony.

The design load of the balcony is per square meter, that is, tons, that is, it takes 4 square meters to bear the weight of 1 ton, and 1 square meter is to bear the weight of 250kg.

The structural arrangement of the balcony includes wall-mounting, beam-lifting and slab-lifting. Wall-mounted: The balcony slab is directly placed on the wall, and its plate shape and span are consistent with the room floor slab, which is mostly used for concave balconies.

Pick beam type: It is to extend the pick beam at both ends of the balcony, and the balcony board rests on the pick beam. Pick plate type:

The overhead type is to cantilevering the balcony slabs.

The balcony load is generally judged according to the balcony live load, and according to the national building code, the balcony live load is generally, that is, no square meter can bear a maximum of 250 kg of weight; Referred to as live load, also known as variable load, is the use or occupation load and naturally occurring natural load caused by people, materials and vehicles applied to the structure.

The balcony load-bearing design is generally 2kn square meters, and the balcony load-bearing is related to the structure of the building itself.

The general balcony has a load of about 200 kg per square meter;

In addition, the end of the balcony is allowed to carry a load of 1 kn m, because this end of the balcony can also bear a concentrated live load of about 100 kg per linear meter.

There are two types of balcony load-bearing ranges:

First, the weight of the balcony itself, including the weight of the balcony floor, upper and lower plastering, railing, etc.;

The second is the change of load-bearing after the balcony.

The national implementation of the balcony load-bearing design standard is: 250 kg square meters, more than this standard will inevitably bring potential safety hazards.

For the sake of its own safety, the area and weight of the balcony are limited, so the furniture on the balcony should choose lightweight folding furniture. The balcony is the most suitable place for families to grow all kinds of flowers and plants, which not only beautifies the balcony, but also can play a role in blocking the sun in the middle of summer.

What is the difference between a recessed balcony and a wall-mounted balcony? Today is a long time to see.

It mainly depends on how much you float out of the balcony, the more you float, the less the load-bearing, and vice versa. There are also mechanical principles, what is the horizontal area of the beam at the bottom of your balcony, and how much is the angle, all have to be calculated. Generally, if the balcony floats out no more than 1500mm, then the load capacity of 500kg is no problem.

The average balcony can hold a weight of 250 kg.

According to the relevant provisions of the National Building Code for Structural Loads, when designing the structure of a dwelling, the live load value of the balcony is taken, that is, the balcony can carry a maximum of 250 kg per square meter. There will be differences in the load-bearing capacity of different types of balconies, and generally the built-in balcony has the largest load-bearing capacity, followed by wall-mounted balconies. The least load-bearing capacity is the balcony with a slab type.

As we all know, in the process of house decoration, the load-bearing wall cannot be removed, and the counterweight wall of the balcony cannot be dismantled. Counterweight walls are used to balance the load on balconies, and removing them may cause structural changes in the house, resulting in a decrease in the load-bearing capacity of balconies. If you want to remove the weight wall, it is best to ask a professional organization to conduct an appraisal to make sure that it will not affect the safety of the house.
