Description
Technical field
The utility model is related to construction field of thermal insulation, and it is temporarily overwintering to be particularly suitable for severe cold area mass concrete
Heat preservation construction.
Background technology
The engineering practice that grinding coagulation soil builds dam in severe cold area is few, and many projects amounts are huge, construction week
Phase is long, needs across year construction for many years, and wherein carry out the overwintering interim heat preservation of dam facing be guarantee dam presentation quality, concrete strength and
The key that can quality and the coming year smoothly return to work.
Extremely frigid zones mass concrete：It refer to high latitude（41 ° of north latitude）More than, winter minimum temperature reach -25 DEG C hereinafter,
Large volume refers to primary concreting 1000m3The above concrete, the interim overwintering heat preservation of concrete are usually main certain thick using covering
The cotton insulation quilt of degree come reduce with extraneous heat transfer and internal-external temperature difference, to make the overwintering temperature of concrete achieve the desired results.
The overwintering layer concrete that First Year pours in process of construction particularly with large-scale hydraulic building, is typically in basic strong constraint
Area, this position concreting thickness is relatively thin but also is the main portions of dam stress, and temperature control difficulty is larger, needs bedding big
Insulation quilt is measured, with the increase of insulation quilt thickness, project cost also increases immediately.
Invention content
The purpose of the utility model is to overcome deposited in existing extremely frigid zones mass concrete temporarily overwintering heat preservation construction
The shortcomings that, provide it is a kind of efficiently, the extremely frigid zones mass concrete overwintering attemperator temporarily of low cost.
Device scheme used by the utility model is a kind of extremely frigid zones mass concrete overwintering attemperator temporarily,
It is characterized by it, and by the horizontal surface concrete of extremely frigid zones, overwintering attemperator, extremely frigid zones side concrete are temporarily overwintering temporarily
The overwintering interim attemperator three parts composition of the exposed structures such as attemperator and extremely frigid zones aperture；
1.1 horizontal surface concretes overwintering attemperator temporarily：It is made of separation layer, insulating layer, waterproof layer and windbreak, by
Under to being above arranged in order, be covered in the overwintering face of concrete as separation layer by plastic film, concrete made to be isolated with outside air,
Rubber-plastic sponge is covered in as insulating layer above plastic film, is kept the temperature to concrete, and three proofings canvas is laid with as waterproof layer
At the top of insulating layer, the continuous gland of sand pocket is placed on surrounding without screening in three proofings canvas overlapping part, with sand pocket setting windbreak
On the overwintering face of dam of block face, intact concrete heat-insulating face has been covered to prevent strong wind from throwing；
1.2 facades or side concrete overwintering attemperator temporarily：It is made of separation layer, insulating layer, waterproof layer, by interior
To being arranged in order outside, be covered on the overwintering facade of concrete as separation layer by plastic film, make concrete and outside air every
From, using XPS benzene plates as insulating layer cover on a plastic film, concrete is kept the temperature, the equivalent heat release of XPS benzene plates
Coefficient is not more than 29.79kJ/（m2•d•℃）, three proofings canvas is laid on insulation layer surface as waterproof layer, finally again with lumps of wood pressure
Item, dovetail expansion bolt are fixed；
1.3 exposed structures overwintering attemperator temporarily：Exposed structure refers to aperture, steel pipe, reinforcing bar and irregular protrusion
Part is made of peripheral burnishing surface, separation layer, insulating layer, waterproof layer, is arranged in order from inside to outside, sets up scaffold and covers
Tablet forms peripheral burnishing surface, is covered in the surface of peripheral burnishing surface as separation layer by plastic film, rubber and plastic sponge is as guarantor
Warm layer covering on a plastic film, is wound banding fixed with iron wire, uses three proofings canvas as waterproof layer and be fixed on insulating layer
Outside, waterproof layer is outer is fixed by lumps of wood press strip, dovetail expansion bolt.
The utility model replaces cotton to keep the temperature and is capped overwintering surface concrete using rubber-plastic sponge and XPS benzene plates.Be conducive to
It can meet code requirement again while shortening project progress, save engineering cost.Moreover, rubber-plastic sponge, XPS benzene plate physical properties
It is compared with cotton insulation quilt, there is many advantages, such as water absorption rate is low, density is small, thermal coefficient is low and fire resistance rating is high, be convenient for
Material stores and work progress management of fire safety.Effect is more preferable, more stable in terms of heat-insulating property, can effectively prevent concrete
Surface is frozen, and while generating crack, concrete is made to keep temperature constant, is also effectively reduced construction cost, is economized on resources.Especially
It is in facade, and cotton insulation quilt is too soft, and poor rigidity, load-bearing capacity is weak, when covering on facade, is easy to slide, and XPS
Benzene plate has certain rigidity, is easy to splice when using on facade.
The pre-plugged temperature monitoring line above separation layer plastic film（Mainly it is made of temperature sensor and conducting wire）So
It draws afterwards and is connected to temperature detection sub-control station, surface temperature of concrete actual conditions are monitored in real time, if being found during thermometric
Inside and outside concrete（Concrete internal temperature detection line is pre-buried in advance when pouring）When the temperature difference is more than 15 DEG C, it should reinforce protecting in time
Temperature delays to remove thermal insulation material, prevents concrete from leading to that stress and the damage of crack occurs because of excessive temperature differentials.
Plastic film thickness used by separation layer is 0.5-0.8mm, and the insulating layer in 1.1 is using multi-layer rubber-plastic sponge weight
It is folded to form, thickness 14-24cm；There is insulating layer to use multilayer XPS benzene plates, overall thickness 56-88cm in 1.2.
The utility model mainly replaces biography by using the mode that new material-rubber-plastic sponge and XPS benzene plates organically combine
Cotton insulation quilt unite as the overwintering surface concrete thermal insulation material of covering.XPS benzene plates are used primarily in concrete side or plane rubber and plastic
The position that sponge can not cover, formation is a kind of efficiently, can be suitble to the interim overwintering heat preservation dress of severe cold area large volume concrete for hydraulic structure
It sets, code requirement can be met, shorten project progress, effectively reduce construction cost, economize on resources.
