Abstract
The invention discloses a heat-insulating structure at the top of an open-air atmospheric storage tank, which comprises a tank top cap (1) and has the structural characteristics that hook nails (2) and a heat-insulating layer (3) are arranged on the tank top cap (1), a wire mesh (4) is arranged outside the heat-insulating layer (3), and a plastering protection layer (5) is arranged on the surfaces of the heat-insulating layer (3) and the wire mesh (4). One hook nail (2) is arranged per square meter, and each hook nail (2) is made of a galvanized wire of which the diameter is phi4mm; each hook nail (2) is exposed for 5cm-6cm on the surface of the heat-insulating layer (3); the wire mesh (4) is a galvanized wire mesh, and the wire diameter is phi1.6mm; and the wire mesh (4) is in a hexagonal or slipknot rhombic structure. The invention enables the plastering protection layer to not only keep the original advantages but also well overcome the original defects to enhance the bearing strength of the plastering protection layer, thereby preventing the plastering protection layer from being torn and leaking water due to frequent stress and overlarge deformation, and achieving the effects of durable protection, safety and stability.
Description
Technical field
The present invention relates to a kind of atmospheric storage tank top thermal insulation construction.
Background technology
In alumina producing factory, there are a lot of open-air atmospheric storage tanks that are provided with to carry out insulated heat.Impaired in order to prevent adiabatic layer, guarantee that thermal insulation gets a desired effect, it is an important key link that the outside face of adiabatic layer is effectively protected.Yet these storage tanks often need carry out Job Operations at the top, therefore, often have operating personal to walk and trample in the groove top line.
The adiabatic layer at atmospheric storage tank top coating material commonly used is as protective cover.The conventional protective cover of wiping one's face usually produces the crack; influence heat insulation effect and lost waterproof action easily; adiabatic layer is damaged; therefore; existing Code for design of heat insulation engineering of industrial equipment and pipe lines, construction and acceptance specification are all stipulated: open-air thermal insulation construction, must not adopt the protective cover of wiping one's face, in the time must adopting; should be on float coat looping felt, paper tinsel or dry goods protective cover, and should be at the coating of looping laminar surface coating waterproof, weather resisting property.
But at present, in engineering thermal insulation, found a kind of practical, effective coating material, the feasible protective cover of wiping one's face does not need looping felt, paper tinsel or dry goods in its appearance again, just directly can use in the open.This coating material is: silicate heat preservation slurry 1m3+ cement 100kg+ microlith powder (or sand) 50kg+ asbestos wool 15kg, and through stirring and sparing into a kind of close-burning compound.Advantage with its protective cover of wiping one's face of constructing is: load-carrying capacity is stronger, does not seep water, and not easy to crack, cost is low, directly is close to the appearance construction of atmospheric storage tank top adiabatic layer; Shortcoming is: facts have proved; if often there is the people to step in the above, be positioned at the protective cover appearance distortion in various degree at storage tank top, localized cracks and small rut perhaps appear; the protection effect that makes it to exist adiabatic layer descends, even seeps water, damages the hidden danger of adiabatic layer.
Summary of the invention
The technical problem to be solved in the present invention is; a kind of heat-insulating structure at top of open-air atmospheric storage tank is provided; deficiencies such as crackle, small rut occur obviously being out of shape or occurring, adiabatic layer is implemented effectively protection often suffering operating personal to trample the back with the atmospheric storage tank top protective cover that overcomes the open-air setting that prior art exists.
Technical scheme of the present invention is as follows:
Hook nail and adiabatic layer are set on the groove top cover, silk screen are arranged, the protective cover of wiping one's face on adiabatic layer and silk screen surface in the outside of adiabatic layer.
Owing to adopted technical scheme of the present invention; the protective cover of wiping one's face has not only kept original advantage; and overcome original defective well; even operating personal is often walked about on the groove top; the local situation of sinking, cheating recessed injustice of protective cover can not appear after using for a long time yet; thereby the protective cover of having avoided wiping one's face is because of being out of shape the excessive hidden danger that is torn, seeps water, and has increased that the protection effect is lasting, the advantage of safety and stability.
Description of drawings
Fig. 1 is scheme drawing of the present invention, sectional elevation;
Fig. 2 is scheme drawing of the present invention, birds-eye view.
In the accompanying drawing: 1-groove top cover, 2-hook nail, 3-adiabatic layer, 4-galvanized wire mesh, the 5-protective cover of wiping one's face.
The specific embodiment:
Embodiments of the invention: on atmospheric storage tank groove top cover 1; earlier burn-on the galvanized iron wire of suitable length as hook nail 2 by the density of one of every sq m; the adiabatic layer 3 of constructing again; with the smooth adiabatic layer outside face that snugly is fixed on of the part of appearing of silk screen 4 usefulness hook nails 2, the protective cover 5 of wiping one's face described in this programme is gone up in construction more then.Silk screen 4 is a galvanized wire mesh, and the iron wire specification is φ 1.6mm, and the silk screen shape is selected hexagon or knot that can be undone by a pull diamond structure for use, and diamond mesh is 25mm * 25mm; Hook nail 2 is selected the galvanized iron wire of φ 4mm for use, appears 5～6 centimetres so that tie up silk screen 4 on adiabatic layer 3 surfaces; On galvanized wire mesh 4, construct to driving fit then and become to do the protective cover 5 of wiping one's face of the thick 25mm of being about.
The protective cover 5 of wiping one's face is a main material with the composite silicate thermal insulation slurry, adds cement 100kg, microlith powder (sand) 50kg, asbestos wool 15kg in 1m3 silicate heat preservation slurry, carries out and spares and stir, and makes it to become a kind of close-burning compound and gets final product.
