Description
Technical field
The utility model belongs to technical field of building construction, is related to the spray equipment of concrete structures cracking resistance, especially
A kind of steel form concrete structures spray cracking resistance device.
Background technique
Large-scale water process reinforced concrete constructional work, in the high temperature environment, such as during hot weather construction, due to environment temperature
Degree is very high, and formation of concrete structures are influenced by temperature shrinkage and drying shrinkage, subtle thermal cracking, this direct shadow in crack occur
Ring leak test and examination.
The generation in large-scale water treatment building crack is due to slab concrete structures, and the middle part heat of hydration is concentrated, in heat
Concrete setting solidifies under conditions of expansion.After the completion of chemical reaction, concrete walls, plate start to receive with the decline of temperature
Contracting, generates stronger tensile stress.Concrete crushing strength is very high, and tensile strength is very low.At this point, periphery has cooled down admittedly
Change, generated inner tensile stress, no free end can be used to shrink, and therefore, concrete is pulled off, and form perforation wall
Thermal cracking.Since crack is less than 0.2mm mostly, it is difficult to repair, and mostly damaging reparation influences service life.
To solve the above problems, needing a kind of spray equipment that the high temperature that will effectively can be generated in casting process is taken away.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind and are evenly distributed, cooling effect is good
A kind of steel form with concrete structures spray cracking resistance device.
A kind of steel form concrete structures spray cracking resistance device, including structures bottom plate, in the upper of structures bottom plate
Side is built with concrete structures, and the end face outside in the concrete structures two sides is separately installed with steel form, special
Sign is: in each steel form backwards to the outer surface of concrete structures, from top to bottom uniform intervals are equipped with multiple sprays
Pipe, multiple spray tubes, which are transversely arranged, to be parallel to each other, and each spray tube surface uniform intervals ipsilateral with steel form are set
It is equipped with multiple hole for water sprayings；Gutter is set in the position of structures bottom plate side, which is connected with a collecting-tank.
Moreover, the spacing for being located at ipsilateral adjacent two spray tube of die plate is 1.5 meters.
Moreover, 0.5 meter of the gutter and concrete structures interval, extend along line direction equal with concrete structures
Setting, the gutter is connected with a collecting-tank.
Moreover, the spacing of two hole for water sprayings adjacent on each spray tube is 0.5 meter, the diameter of each hole for water spraying is 1mm.
The advantages and positive effects of the utility model are as follows:
In the utility model, when carrying out pouring construction using steel form, the spray tube of parallel interval setting, which is evenly arranged on, to be constructed
The two sides of object, during gradually pouring from the bottom to top, according to it is different pour height using corresponding position spray tube into
Temperature difference is effectively reduced to largely take away the heat generated in casting process to reduce caused by thermal expansion in row spray
It acutely shrinks, effectively prevent the generation in crack；The setting of 1.5 meters of tube spacing of spray and the hole for water spraying aperture of spray tube are set as
1mm is a kind of preferred embodiment, can save cooling water used on the basis of effective temperature-reducing；The setting in gutter
For the cooling flowed down water to be imported collecting-tank, and cooling is carried out in collecting-tank and is recycled again.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment 1 in the utility model.
Specific embodiment
It elaborates below by embodiment to the utility model, the embodiment is illustrative instead of limiting
, protection scope of this utility model cannot be limited by this.
A kind of steel form concrete structures spray cracking resistance device, including structures bottom plate, in the upper of structures bottom plate
Side is built with concrete structures 2, and the end face outside in the concrete structures two sides is separately installed with steel form, this reality
It is with novel innovation, in each steel form backwards to the outer surface of concrete structures, from top to bottom uniform intervals are installed
There are multiple spray tubes 1, multiple spray tubes, which are transversely arranged, to be parallel to each other, each spray tube and the ipsilateral surface of steel form
Uniform intervals are provided with multiple hole for water sprayings；In the position of structures bottom plate side, gutter 4, the discharge outlet and a collecting-tank are set
It is connected.
In the present embodiment, the spacing of adjacent two spray tube ipsilateral positioned at die plate is 1.5 meters.
In the present embodiment, 0.5 meter of the gutter and concrete structures interval, along side parallel with concrete structures
To being extended, the gutter is connected with a collecting-tank.
In the present embodiment, the spacing of two adjacent hole for water sprayings is 0.5 meter on each spray tube, and the diameter of each hole for water spraying is
1mm。
In the present embodiment, the collecting-tank is arranged far from concrete structures, and preferred water requirement should be vertical not less than 4
Square rice.
In the present embodiment, pump machine is installed in gutter.
In the present embodiment, for having top cover building if any the pond etc. of ceiling, to be roused in manhole, manhole installation, air inducing
Machine 3 is discharged damp-heat air, improves the effect of spray cooling.
When the utility model is used, 20 minutes unlatching spray tubes before casting concrete carry out template cooling；Pour knot
End in 72 hours sprays after beam；Water control is at vertical m/h of every linear meter(lin.m.) water consumption 0.2, hydraulic pressure, with top layer's horizontal shower pipe
Spray effect, which can normally be played, to be advisable；It is completed 72 hours pouring, starts to loosen template, and by top layer's spray tube, move on to top
Portion closes other horizontal shower pipes using maintenance of pouring water.
In the utility model, when carrying out pouring construction using steel form, the spray tube of parallel interval setting, which is evenly arranged on, to be constructed
The two sides of object, during gradually pouring from the bottom to top, according to it is different pour height using corresponding position spray tube into
Temperature difference is effectively reduced to largely take away the heat generated in casting process to reduce caused by thermal expansion in row spray
It acutely shrinks, effectively prevent the generation in crack；The setting of 1.5 meters of tube spacing of spray and the hole for water spraying aperture of spray tube are set as
1mm is a kind of preferred embodiment, can save cooling water used on the basis of effective temperature-reducing；The setting in gutter
For the cooling flowed down water to be imported collecting-tank, and cooling is carried out in collecting-tank and is recycled again.
