Abstract
The utility model discloses a kind of temperature control cracking-proof bridge deck containing phase-changing energy storage material, it is characterized in that: comprise granular cushion, on described graded broken stone layer, be coated with successively concrete base layer, heat-insulation mortar bed and concrete or asphalt surface course, between described heat-insulation mortar bed and concrete or asphalt surface course, be provided with energy-storage layer, described energy-storage layer by stainless steel hollow section side by side, be filled in the cement mortar between stainless steel hollow section and the phase-change material that is positioned in stainless steel hollow section forms.The utility model advantage is compared with prior art: structure of the present utility model both can play temperature control function, can prevent again the generation in bridge deck crack.
Description
Technical field
The utility model relates to bridge deck structure, relates in particular to a kind of temperature control cracking-proof bridge deck containing phase-changing energy storage material.
Background technology
At present, the impact of climate factor, bridge deck easily produce and because temperature is high, make the too high problem of bridge deck temperature in the area of temperature difference great disparity, also occur to make because temperature is too low bridge floor to produce the phenomenon in crack.Nowadays, common bridge deck structure cannot overcome these problems, causes bridge surface mangle serious, produces potential safety hazard.Yet phase-change material is a kind of varying with temperature and change physical property and the material of latent heat can be provided.The process that changes physical property is called phase transition process, and at this moment phase-change material will absorb or discharge a large amount of latent heat.Phase-change temperature control concrete is to take the intelligent concrete of the composite phase-change material that concrete material is matrix.Phase-change temperature control concrete is applied to building energy saving field, has the incomparable thermal capacitance of ordinary concrete material, utilizes it to make exterior wall material, will be conducive to the stable of interior temperature, thereby improves thermal comfort, reaches energy-conservation object.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, provides a kind of temperature control cracking-proof bridge deck containing phase-changing energy storage material.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of temperature control cracking-proof bridge deck containing phase-changing energy storage material, it is characterized in that: comprise granular cushion, on described graded broken stone layer, be coated with successively concrete base layer, heat-insulation mortar bed and concrete or asphalt surface course, between described heat-insulation mortar bed and concrete or asphalt surface course, be provided with energy-storage layer, described energy-storage layer by stainless steel hollow section side by side, be filled in the cement mortar between stainless steel hollow section and the phase-change material that is positioned in stainless steel hollow section forms.
The diameter of described stainless steel hollow section is 10cm.
This novel bridge panel is owing to having increased one deck phase-changing energy storage material in basic unit, when reaching transformation temperature, the temperature of bridge deck rising can occur to change mutually, absorb in bridge deck hydrated cementitious heat and store energy in phase-change material, thereby controlling rate of rise in temperature and the highest temperature is appreciated; In like manner, when bridge deck surface temperature declines, phase-change material occurs to change mutually again, by the thermal release of storage out, reduces bridge deck temperature decrease speed, prevents that the too fast reduction of temperature from causing bridge deck cracking.
The utility model advantage is compared with prior art: structure of the present utility model both can play temperature control function, can prevent again the generation in bridge deck crack.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of temperature control cracking-proof bridge deck containing phase-changing energy storage material, it is characterized in that: comprise granular cushion 1, on described graded broken stone layer 1, be coated with successively concrete base layer 2, heat-insulation mortar bed 3 and concrete or asphalt surface course 4, described heat-insulation mortar bed 3 and concrete or asphalt surface course 4 between be provided with energy-storage layer 5, described energy-storage layer 5 by stainless steel hollow section 6 side by side, be filled in the cement mortar 7 between stainless steel hollow section 6 and the phase-change material 8 that is positioned in stainless steel hollow section 6 forms; The diameter of described stainless steel hollow section 6 is 10cm.
The above-mentioned specific embodiment is exemplary, is to be this patent to be comprised to the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do be anyly equal to change or modify, all fall into the scope that this patent comprises.
