Detailed description of the invention
Hereinafter embodiment of the present utility model is described in detail, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
Shown in Figure 2, according to embodiment of the present utility model, radial canal metope structure includes the steel bar layer 1 of formed by integrally casting molding, radial canal 2 and concrete layer 3, and radial canal 2 is positioned at the steel bar layer 1 side near indoor, and concrete layer 3 is coated on outside steel bar layer 1 and concrete layer 3.
In radial canal metope structure of the present utility model, radial canal 2 is in steel bar layer 1 near indoor side, and directly it is integrated with concreting during metope molding, this allows in the middle of steel bar layer 1 without considering the offering question of radial canal 2, operation and difficulty of construction can be reduced, reduce cost.Radial canal 2 is arranged on steel bar layer 1 near indoor side, distance between the internal layer edge of radial canal 2 and metope structure is diminished, reduce the thermal loss during the heat in radial canal 2 is radiated indoor, improve heat conduction efficiency, it is possible to the energy utilization efficiency of enhanced rad pipe 2.Owing to radial canal 2 is positioned at steel bar layer 1 near indoor side, when radial canal 2 goes wrong needs replacing or maintenance, directly steel bar layer 1 can be knocked open near the concrete layer 3 of indoor side, after radial canal 2 is replaced or keeps in repair, again by concrete layer 3, radial canal 2 is fixed in metope structure, without steel bar layer 1 is processed, therefore reduce maintenance difficulty, improve the convenience of metope structure follow-up maintenance.Radial canal 2 is arranged in metope structure, for the mode that radial canal 2 is arranged on awning structure, structure is more reasonable, it is possible to reduces the lost adverse effect caused for indoor temperature distribution of window heat, improves uniformity and the comfort level of indoor temperature distribution.
For example, metope structure of the prior art, typically radial canal 2 is arranged between inside and outside two-layer bar-mat reinforcement, the integral thickness making metope structure probably arrives about 200mm, radial canal 2 is radiated the distance of indoor and is about between 60mm to 110mm, and therefore radial canal 2 at least needs can to arrive indoor through the concrete layer that 60mm is thick and effectively conducts heat.
And after using structure of the present utility model, radial canal 2 is owing to being arranged on the side near indoor of steel bar layer 1, hence in so that the distance that radial canal 2 is radiated indoor can be reduced to below 60mm, in order to ensure radial canal 2 stability of mounting structure in concrete layer 3, radial canal 2 is radiated the distance of indoor and can control between 30mm to 40mm, this just substantially reduces the thickness that radial canal 2 needs the concrete layer 3 of process so that the heat of radial canal 2 can more quickly be delivered to indoor.
When being provided with window on radial canal metope structure, radial canal 2 have walk around window position dodge region 4.In conjunction with shown in Figure 5, it is however generally that, if radial canal 2 is arranged on awning structure, so in actual heat supplying process, indoor isothermal line shows as, and the radian being inwardly recessed the closer to the window's position isothermal line is the biggest, namely scatter and disappear the biggest the closer to the window's position heat, temperature is the lowest.Owing to being provided with window at window, temperature herein is affected bigger by structure and the material of window itself, therefore to the temperature difference at heat at the window's position and other regions can be avoided as best one can excessive, the uncomfortable impression of cause the user, should try every possible means so that indoor isothermal line is more mild, Temperature Distribution is the most uniform.
In conjunction with shown in Figure 6, after using metope structure of the present utility model, radial canal 2 is set directly in the metope structure with window, now heat is to be distributed to indoor by the radial canal 2 in metope structure, therefore in the position the closer to metope structure, heat is the biggest, and uniformly distribute to thereabout, even if there being partial heat to scatter and disappear still through window, but generally speaking, heat at window constantly distributes the reason of heat due to the radial canal 2 in metope structure, significantly reduce with the heat difference in fore-and-aft plane around, temperature difference at temperature at this and other regions is diminished, therefore the uniformity of whole indoor temperature can be improved, improve comfort level when user uses.By in Fig. 6 it can be seen that after being arranged on by radial canal 2 and having on the metope structure of window, the isothermal line curve radian near the position of window reduces, namely heat reduces in the change in location near window, and Temperature Distribution is more uniform.
