Description
Technical field
The utility model relates to a kind of panel-assembled cold store polyurethane laminboard fixing device for installing.
Background technology
Since the nearly more than ten years, the individual layer panel-assembled cold store that newly-built large cold storage employing R717 is the split type unit of cold-producing medium increases gradually.This individual layer panel-assembled cold store as main structure body, adopts the peripheral structure of the excellent polyurethane metal sandwiched plate of heat-insulating property as building with steel work.The width of polyurethane metal sandwiched plate is limited, needs the splicing through plate and plate, and utilizes bolt to be connected with the steel work purlin, thereby be fixed on the main body steel work.Conventional method of attachment is that the surfaces externally and internally that tap bolt directly passes sandwiched plate is connected on the steel work purlin; As producing a large amount of cold bridges by this joint construction and mounting method assembly unit meeting; The generation meeting of cold bridge has bigger influence to the operation of freezer, influences heat insulation effect, has increased energy consumption simultaneously.In order to solve the problem of insulation, must be in the storehouse many-sided technology such as joint construction design, fabrication and installation node of plate break through.
Summary of the invention
The purpose of the utility model is to provide a kind of panel-assembled cold store polyurethane laminboard to prevent the cold bridge fixing device for installing; This apparatus structure is simple; Can avoid the generation of cold bridge, reduce the loss of heat in the freezer, and the bulk strength of polyurethane metal sandwiched plate and heat-proof quality remain unchanged.
To achieve these goals, the utility model adopts following technical scheme:
A kind of panel-assembled cold store polyurethane laminboard is prevented the cold bridge fixing device for installing, comprises some groups of built-in metal fixed components, some connecting elementss and tap bolt; Said built-in metal fixed component is embedded in the polyurethane laminboard in process of factory production; Said connecting elements is for being bent into the rectangle sheet material of 180 degree through secondary; Have through hole on the connecting elements; The through hole that tap bolt passes on the connecting elements is connected connecting elements with the built-in metal fixed component; Second half of connecting elements pushed down the steel work purlin, thereby polyurethane laminboard is connected with connecting elements through the built-in metal fixed component and is fixed on the steel work purlin.
The spill of said built-in metal fixed component for being bent into by sheet material.The bottom surface of said built-in metal fixed component spill is near the sandwiched plate inner face.
Have two through holes arranged side by side on the said connecting elements.
The utility model is through built-in metal fixed component in the polyurethane metal sandwiched plate; And designed special-purpose connecting elements; Through tap bolt polyurethane metal sandwiched plate and steel work purlin are fixed, thereby avoided the generation of cold bridge, and strengthened the bonding strength of storehouse plate; Reduce the storehouse plate because of the distortion that external loads causes, reduced the risk of freezer gas leakage; And the bulk strength and the heat-proof quality of polyurethane metal sandwiched plate remain unchanged.
The fixture structure of the utility model is simple, and is safe and reliable, controllable product quality, and anti-cold bridge effect is obvious, and favorable economic benefit and social benefit are arranged.
Description of drawings
Fig. 1 is the anti-cold bridge fixing device for installing structural representation of the utility model panel-assembled cold store polyurethane laminboard;
Fig. 2 is the fastening devices partial structurtes sketch map of the utility model;
Fig. 3 be among Fig. 2 A-A to sketch map.
Among the figure: 1 built-in metal fixed component, 2 connecting elementss, 3 tap bolts, 4 steel work purlins, 5 polyurethane laminboards.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Referring to Fig. 1 to Fig. 3, a kind of panel-assembled cold store polyurethane laminboard is prevented the cold bridge fixing device for installing, comprises some groups of built-in metal fixed components 1, some connecting elementss 2 and tap bolt 3;
Said built-in metal fixed component 1 is embedded in process of factory production in the polyurethane laminboard 5, the spill of built-in metal fixed component 1 for being bent into by sheet material, and this sheet material is steel plate, the bottom surface of built-in metal fixed component 1 spill is near the sandwiched plate inner face; Built-in metal fixed component 1 is used for the structural strength of the inboard steel plate of reinforcement clamp central layer, and pre-buried quantity generally is provided with after calculating according to the quantity and spacing of steel work purlin 4, and every group is two metal fixed components, and its spacing is 550mm.
Said connecting elements 2 is for being bent into the rectangle sheet material of 180 degree through secondary; Material is a steel; Have two through holes arranged side by side on the connecting elements 2; Tap bolt 3 passes through hole and built-in metal fixed component 1 concave bottom surfaces on the connecting elements 2, and connecting elements 2 is connected with built-in metal fixed component 1; Second half of connecting elements 2 pushed down steel work purlin 4, and the cross section of steel work purlin 4 is I-shaped, thereby polyurethane laminboard 5 is connected with rectangle steel connecting elements 2 through built-in metal fixed component 1 and is fixed on the steel work purlin 4.
Said connecting elements 2 is used to be arranged on steel work purlin 4, plays support bracket fastened effect; Tap bolt 3 is processed for stainless steel.
Said built-in metal fixed component 1 and connecting elements 2 are after stainless steel tap bolt 3 is fixed, and the overlength polyurethane laminboard 5 of panel-assembled cold store can effectively be fixed on the steel work purlin 4, thereby have reduced the possibility that cold bridge forms.
Owing to be fixing polyurethane metal sandwiched plate 5 in the inboard of freezer; Just punched sandwiched plate 5 inboard steel plate and built-in fittings, thereby do not destroyed the insulation layer of sandwiched plate 5, destroyed insulation layer thereby reduced because of geometrical clamp central layer 5; The cold bridge that causes produces; Greatly reduce the loss of heat in the freezer, reduced energy consumption, meet the energy-saving low-carbon economy of society's promotion now.In addition, because metal embedded part is directly pre-buried in the process of factory production,, guaranteed the reliability of freezer at day-to-day operation so technical indicators such as polyurethane metal sandwiched plate intensity, insulation and globality do not change.
More than be merely the preferred embodiment of the utility model; It is not the protection domain that is used to limit the utility model; Therefore, any modification of being done within all spirit and principles at the utility model, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
