Description
Technical field
The present invention relates to large-scale experiment casing field, particularly a kind of heavy load bottom plate of walk-in test chamber.
Background technology
The walk-in test chamber body is called storehouse plate casing again, the inside of its casing is the operating room, mainly be to be used to put the space that the scale-up version test specimen carries out the high and low temperature damp heat test or other service is provided for the user, the operating room of this casing from several cubic metres to last kilostere, usually there are personnel to walk about in the operating room or vehicle travels, System for Large-scale Specimen in the operating room also from the hundreds of kilogram to several thousand kilograms, if the bottom strength of operating room is not enough, trample or test specimen is put pressure through personnel, pit will occur even destroy base plate; In case storehouse plate box bottom has pit, when doing damp and hot experiment, floor just occurs ponding easily or freezes, and phenomenons such as wet and slippery occur, brings inconvenience and danger to staff's walking.Because the volume of casing is big, normally use the mode of freezing the storehouse jigsaw to make up, the bottom of storehouse plate casing is a storehouse plate box bottom, just as the ground in room, because of storehouse plate box bottom area is bigger, generally is made up of a plurality of relatively independent jigsaw.Because this large-scale experiment casing mainly is to be used for System for Large-scale Specimen is carried out height, the low temperature damp heat test, temperature range in the operating room is generally-70 ℃～+ 150 ℃, at a certain specific temperature spot, by in the operating room, adding modes such as water vapour or water smoke, make the humidity in the operating room reach test requirements document, therefore doing generally speaking on the inwall of operating room of damp heat test and the floor all to have the condensation phenomenon to occur, and the large-scale experiment case the operating room in put the test specimen of putting usually and have hundreds of to arrive thousands of kilogram weights, storehouse plate box bottom is incubated and becomes indeformable is the important indicator that storehouse plate casing is done good and badly.Storehouse plate box bottom is as the easiest impaired position of plate casing, storehouse, and its intensity influences the service life of storehouse plate casing to a great extent.Consider storehouse plate box bottom if only go out to send, it is made the cement flooring just can satisfy ground intensity, but the cement flooring is not incubated,, will consume a large amount of energy for keeping the temperature in the case if adopt the cement flooring from the intensity angle.Because-70 ℃～+ 150 ℃ temperature in the plate casing operating room, storehouse, its low-temperature condition is to freeze by refrigeration compressor to obtain, and the condition of high temperature is to heat by electric heater to obtain, for energy savings storehouse plate casing also will solve the insulation problem.Usually the insulation of storehouse plate box bottom generally is to adopt to fill the polyurethane blowing agent cut off heat conduction between floor and the lower panel between the floor of base plate and lower panel.But this floor adopts 1 millimeter corrosion resistant plate to make, the bonding mode of blowing agent and the dependence of plate face self is connected as a whole warming plate, this warming plate has certain bearing capacity to uniform load, every square metre approximately can be born 1000 kilograms, its bearing capacity is relatively poor, if often concentrfated load is arranged, blowing agent and inner panel come off easily, cause base plate destroyed.In order to strengthen the bearing capacity of storehouse plate box bottom, reduce simultaneously the heat conduction of warming plate again, so the common practice of present storehouse plate box bottom aspect load-bearing has two kinds: a kind of at bottom surface, floor reinforcement, just added muscle is fitted in the bottom surface, floor, and muscle does not have and the floor, lower panel or base are connected as a single entity, spacing between muscle and the muscle is also bigger, though such structure can be cut off the heat conduction, but bearing concentrfated load or through personnel, after vehicle rolls for a long time, because reinforcement and floor be welding not, usually use after 1～2 year, big space all can appear between floor and the reinforcement, the floor is easy to generate local deformation and depression occurs, can form ponding in these depressions when doing damp heat test.Another kind is to add channel-section steel under the floor, with the notch end face of channel-section steel to the side, channel-section steel is shelved on support floor between the other channel-section steel frame in floor and base plate bottom, existing supporting role, serve as disconnected heat bridge again simultaneously, but the sideways support strength of notch end face of channel-section steel can weaken, and channel-section steel and floor and channel-section steel bridge joint touch, the heat that the floor absorbs can be conducted to the channel-section steel frame from channel-section steel and outwards be discharged, and the effect of heat insulation that causes it to serve as disconnected heat bridge is also bad.And the draining on the floor of these two kinds of structures all is the form that adopts the ground small opening, and because of floor area is big, the ground small opening is provided with and has lacked impeded drainage, and the ground small opening has been provided with many and has reduced heat insulation effect greatly.Mainly there is following shortcoming in the storehouse plate box bottom of comprehensive above structure:
The first, 1 millimeter corrosion resistant plate is all adopted on the floor in above two kinds of structures, and floor self is not anti-skidding, for anti-skidding, the way of pasting emery cloth strip on corrosion resistant plate is arranged, but not attractive in appearance, uses after one to two year, comes off with regard to emery cloth strip occurring easily; The sliding aluminium sheet of setting up defences on the upper berth, floor is also arranged, but the fixed form of anti-skidding aluminium sheet is to adopt staking to be connected with the floor, through trampling for a long time, staking place occurs slit and anti-skidding aluminium sheet and floor binding face easily and the gap occurs, cause the water capacity easily to be penetrated in the heat-insulation layer and anti-skidding aluminium sheet under water can ooze out when being subjected to gravity.
The second,, when carrying out humid test, because the expanding with heat and contract with cold of material, draw distortion easily with the drawing crack of junction, floor or with the plate face on floor owing to adopt with the directly welding mutually of several floors.
Three, because the floor is thinner, no muscle position just is difficult to bear concentrfated load or less shock loading.
Four, because the intensity difference of storehouse plate base plate so its base muscle often guarantees its intensity, but is not easy to install smooth like this.
Five, adopt floor drain to work indoor water-supply overflow, for the floor that does not have the inclination angle, the overflow effect is bad.
Summary of the invention
The objective of the invention is deficiency at above-mentioned prior art existence, a kind of heavy load bottom plate of walk-in test chamber is provided, it is by after being provided for keeping the scaffold assembly of base plate shape and the floor pan assembly that is welded to be welded into piece, the face of overlooking that again each piece is weldingly connected into an integral body is the storehouse plate box bottom of rectangle, the gutter channel of storehouse plate box bottom is between the floor of each piece and floor and between floor and the retainer, the floor pan assembly and being used to of being welded keeps being provided with the disconnected heat bridge of load-bearing between the scaffold assembly of base plate shape, the overflow effect that can either improve storehouse plate box bottom solves anti-skidding problem, can solve the floor again and be subjected to local assault to be out of shape and to be out of shape, can also improve heat insulation effect because of the drawing crack of cold and hot variation generation.
The object of the present invention is achieved like this: storehouse plate box plate is combined by the polylith piece, and described each jigsaw comprises the scaffold assembly that is used to keep the base plate shape, floor pan assembly and heat-insulation layer are welded;
The described scaffold assembly that is used to keep the base plate shape by the square steel crossbeam of retainer, at least two and retainer welding, be welded on bottom panel in square steel crossbeam lower end and the retainer, a plurality ofly be welded on square steel crossbeam upper end and constitute with the staggered brace rod of crossbeam, leave the strain gap between its square steel crossbeam and the ground;
