Abstract
A reinforced concrete wall structure for preventing cracking is characterized in that the reinforced concrete wall is of a vertical cantilever structure, double rows of reinforcing mesh sheets are arranged in the reinforced concrete wall, the lower end of the reinforced concrete wall is connected with a foundation, and the upper end of the reinforced concrete wall is connected with a plate or a beam. When the wall body is in a vertical cantilever structure and is only connected with the beam, the top of the wall body is provided with a hidden beam, the hidden beams are vertically arranged at intervals of 1.5-2.5 m, and the hidden columns are longitudinally arranged at intervals of 3.0-5.0 m. When the top of the wall body is connected with the plate, the top of the wall body does not need to be provided with hidden beams, the hidden beams are only arranged at intervals of 1.5-2.5 m along the vertical direction, and the hidden columns are arranged at intervals of 3.0-5.0 m along the longitudinal direction. The structure and the construction method thereof are simple and easy to implement, can effectively reduce the probability of cracks appearing on the reinforced concrete wall, and ensure the structural safety and normal use of the reinforced concrete wall.
Description
Technical field
It is more particularly to a kind of to prevent the reinforced concrete wall structure of cracking and its apply the invention belongs to building engineering field
Work method.
Background technology
In process of construction, cast in situ ferroconcrete wall body cracking is more universal, particularly underground engineering outer wall cracking
It is more, and crack is often Vertical Cracks, along wall length direction than more uniform distribution, serious meeting forms through crack, therefore
The phenomenons such as seepage, steel bar corrosion are often resulted in, so that performance reduction of the structure under long-term use state, serious has an effect on
Use function.
The reason for causing reinforced concrete wall to ftracture, in addition to the deficiency of concrete material itself, mainly external force
The result of effect, is mainly temperature stress and more than the visible active force in the outside of its ability to bear (such as shock, side pressure in external force
Deng).At present, the common practice for preventing wall crazing be by the use of wall double steel bar mesh sheet as prevent cracking temperature
Muscle, but effect of anti-cracking is not often obvious.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, a kind of reinforced concrete wall knot for preventing and ftractureing is developed
Structure and its construction method, the structure and its construction method are simple and easy to apply, can effectively reduce reinforced concrete wall there is crack
Probability, it is ensured that the structure of reinforced concrete wall is safe and normally uses.
The present invention solves its technical problem and is achieved through the following technical solutions：
A kind of reinforced concrete wall structure for preventing from ftractureing, the double reinforced mesh of configuration in reinforced concrete wall, its
It is characterised by：Wall is vertical cantilever design, and its lower end connects with basis, and upper end connects with plate or beam.
Dark beam together is set at the top of above-mentioned wall, and vertically by spacing 1.5m~dark beam of 2.5m settings, between being pressed along longitudinal direction
Away from 3.0m~5.0m, sleeper is set.
Above-mentioned wall vertically sets dark beam by spacing 1.5m~2.5m, sets dark by spacing 3.0m~5.0m along longitudinal direction
Post.
The construction procedure of the above-mentioned reinforced concrete wall structure for preventing from ftractureing is as follows：
(1) conventional method is first according to wall longitudinal reinforcement and sleeper reinforcing bar insertion basis, and pours base concrete；
(2) sequentially colligation wall horizontal reinforcement and sleeper, dark beam steel；
(3) wall form is installed and is reinforced using pull-tab or Screw arbor with nut at both-ends；When using plank sheathing, template thickness is not small
Heat-insulation layer is set on the outside of template when 15mm, winter construction；When using metal form, in the construction of any season in template
Outside sets heat-insulation layer；
(4) casting concrete according to a conventional method, top exposed parts covering and heat insulating layer；
(5) curing in the mold is no less than 7 days, and then form removal template, plastic sheeting moisture-keeping maintaining is pasted on concrete wall surface.
The advantages of the present invention are：
1st, the reinforced concrete wall structure for originally preventing the reinforced concrete wall structure and construction method of cracking from producing,
Its wall lower end connects with basis, and upper end connects with plate or beam or is vertical cantilever design, and reinforced concrete wall configures double steel
Muscle mesh sheet；When wall is vertical cantilever design or when only connecting with beam, dark beam together is set at the top of wall, and between vertically pressing
Dark beam is set away from 1.5m~2.5m, sleeper is set by spacing 3.0m~5.0m along longitudinal direction；When wall top connects with plate, wall
Top is not required to set dark beam, only vertically sets dark beam by spacing 1.5m~2.5m, is set by spacing 3.0m~5.0m along longitudinal direction
Sleeper.The present invention sets dark beam, sleeper, improves concrete lateral rigidity and cracking resistance, and double layer bar can improve reinforcing bar and mix
Solidifying soil surface crack resistance.
2nd, originally prevent the construction method of the reinforced concrete wall structure of cracking from providing concrete mix premature coagulation
Required constant environment temperature and humidity, it is to avoid the generation of curing temperature change drastically, reinforced concrete shear wall is poured
Build rate of rise steady growth with the extension of suitable curing temperature of rear intensity, early strength is high, can compensation temperature should
Adverse effect of the power to structure, it is to avoid the generation in crack.Simultaneously because early strength is high, it is particularly suitable for periphery and produces vibration lotus
The operation of load, also can carry out the operations such as foundation ditch backfill ahead of time.
3rd, the reinforced concrete wall structure and construction method of cracking is originally prevented to be applied to four seasons spring, summer, autumn and winter, and various temperature
Spend the environment of acute variation, convenient and quick construction.
