Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating roofs, and more particularly to a heat-insulating roof structure. Background Art

[0002] The roof insulation layer is formed by installing building materials on the upper layer of the roof. It can protect the roof from the sun and insulate it from heat, thereby improving the comfort of the top floor.

[0003] There are two main forms of roof insulation. One is that the outer layer is based on the reflection principle. Through the laying of paint, most of the light received by the roof surface is reflected out, thereby avoiding the temperature rise caused by long-term exposure to light; the other form is to block the external heat through the laying of thermal insulation materials to prevent external heat from entering the room.

[0004] Existing insulation materials are typically provided as a single piece of board. For example, the thermal conductivity of common cement foam insulation board can reach as low as 0.045 W / m·K, while the average thermal conductivity of air is approximately 0.025 W / m·K. Therefore, heat loss during heat transfer on the roof is low. However, since the same material is used for heat transfer within the board, the heat loss rate is low during heat transfer, and the insulation effect is relatively poor.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a heat-insulating roof surface structure. By utilizing the setting of the water storage cavity in the partition, the temperature transfer in the partition during solar exposure needs to pass through the transmission loss of air and liquid in the water storage cavity and then transfer the temperature downward, thereby improving the thermal insulation effect.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: an insulating roof surface structure, including a roof keel, the roof keel including an outer frame, a horizontal keel fixedly connected to the outer frame, and a plurality of partitions are clamped on the horizontal keel, the top of the partition is provided with a groove, the partition is provided with abutment grooves at the diagonal position of the groove, the surface of the partition is provided with a plurality of protrusions, a water storage cavity is provided in the partition, and the partition is provided with a plurality of through holes at the upper end of the water storage cavity for conducting to the water storage cavity.

[0008] The utility model is further configured such that the distance between two adjacent transverse keels is equal to the distance between two grooves when the two partitions are combined, and the partitions are provided at the bottom ends of the grooves with insertion grooves for the transverse keels to be inserted into.

[0009] The utility model is further configured as follows: the vertical keel is arranged between the left and right adjacent partitions, the top end of the vertical keel is fixedly connected to a guide frame, and the side wall of the partition is provided with a guide plate extending into the guide frame.

[0010] The present invention is further configured such that: the top of the guide frame is flush with the top of the vertical keel, and the length of the guide frame is greater than the length of the vertical keel.

[0011] The utility model is further configured such that: the two side surfaces of the water storage cavity are parallel to the bottom surface of the partition.

[0012] The utility model is further configured as follows: the through hole is located in the upper middle position of the water storage cavity away from the side of the transverse keel.

[0013] The utility model is further configured as follows: the partition is provided with a chamfer at one end of the through hole away from the water storage cavity.

[0014] The utility model is further configured such that the diameter of the through hole gradually decreases as it approaches the water storage cavity.

[0015] In summary, the present invention has the following beneficial effects:

[0016] By setting up the water storage cavity in the partition, the temperature transfer in the partition during sunlight exposure needs to be able to transfer downward after passing through the air and liquid in the water storage cavity, thereby reducing heat loss and improving the thermal insulation effect; when it rains, the convex strips can guide the flow direction of rainwater, and the setting of the through holes can store part of the rainwater in the water storage cavity during the downward flow of rainwater, and absorb heat through water in the subsequent insulation process, further improving the temperature transfer loss.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] An insulating roof surface structure, such as Figure 1-3 As shown, it includes a roof keel, which is supported by several heavy columns in the room and is used to bear the weight of the upper end, playing a role of stability and firmness. The roof keel includes an outer frame 1, a horizontal keel 2 fixedly connected to the outer frame 1, and a vertical keel 3. The outer frame 1 is used to connect the horizontal keel 2 and the vertical keel 3, and is fixedly connected to several load-bearing columns in the room on the lower side. The staggering of the horizontal keel 2 and the vertical keel 3 forms several areas on the roof, which can increase the contact area and supporting capacity of the roof keel to the upper objects, thereby improving the service life.

[0025] like Figure 1-3 As shown, a number of partitions 4 are clamped on the horizontal keel 2. By installing the partitions 4, the upper end and the lower end of the roof keel are separated, which has the effect of isolating the indoor and outdoor temperatures. A water storage cavity 8 is provided in the partition 4. When the water storage cavity 8 is in a water-free state, the temperature transferred from the inner side of the partition 4 will be disconnected in the water storage cavity 8, thereby increasing the loss in the heat transfer process and reducing the impact on the indoor temperature.

[0026] like Figure 1-5 As shown, when it rains indoors or outdoors, the arrangement of several partitions 4 can also play a water-blocking effect. When the upper and lower partitions 4 are connected, the abutment groove 6 at the bottom end of the upper partition 4 is above the groove 5 of the lower partition 4. The water flows toward the lower partition 4 under the action of gravity and the guidance of the upper partition 4. Several protrusions 7 arranged on the surface of the partition 4 can prevent the water from diffusing when it flows obliquely under the action of gravity, and avoid water seepage. Several through holes 9 are provided on the surface of the partition 4, and the through holes 9 are connected to the water storage chamber 8. During the flow of water, it can enter the water storage chamber 8 from the through holes 9 for storage. After the water storage chamber 8 is filled with water, the excess water will flow downward under the guidance of the partition 4.

[0027] like Figure 4-5 As shown, after there is liquid in the water storage chamber 8, during the sun exposure process, the carrier used to absorb heat and transfer temperature in the water storage chamber 8 will become water. The specific heat capacity of water is greater than that of the partition 4 material and air. The water in the water storage chamber 8 evaporates after absorbing heat, and the evaporation process will condense, causing the temperature in the partition 4 to circulate, which can greatly increase the heat transfer loss in the partition 4 and achieve a good thermal insulation effect.

[0028] like Figure 1-3As shown, the spacing between two adjacent transverse purlins 2 is equal to the spacing between the two grooves 5 when the two partitions 4 are combined. The partition 4 is provided with an insertion groove 10 for the transverse purlin 2 to be inserted at the bottom end of the groove 5. During the installation process, a partition 4 is first clamped on the transverse purlin 2 for preliminary support. At this time, the other end of the partition 4 is also on the partition 4, which can prevent the partition 4 from falling during installation. When installing the next partition 4, the installation position of the newly installed partition 4 is reserved by lightly lifting the previous partition 4, and the top of the previous partition 4 is placed on the lower partition 4. In this way, the installation of the partition 4 can be easily completed by the cycle, and the two partitions 4 can be connected and supported on the transverse purlin 2 to improve the support strength.

[0029] like Figure 1-3 When the trough 1 is closed, the trough 11 is opened, and the trough 1 is opened, so that the trough 1 is opened, and the trough 1 is opened.

[0030] like Figure 1-5 As shown, the two side surfaces of the water storage chamber 8 are parallel to the bottom surface of the partition 4. The parallel setting can accelerate the accumulation of liquid and make the inner cross-section of the partition 4 equal when it is placed horizontally, so that the heat transfer thickness in the partition 4 is uniform and the temperature transfer effect is uniform; the through hole 9 is arranged in the middle and upper position of the water storage chamber 8 away from the side of the horizontal keel 2. Such a setting can ensure that there is at least half of the water storage space in the water storage chamber 8, thereby enhancing the water storage effect and the temperature insulation effect.

[0031] like Figure 4-5 As shown, the partition 4 is provided with a chamfer on the side of the through hole 9 away from the water storage chamber 8. The chamfer setting can increase the range of water flowing into the surface of the partition 4 and improve the probability of water inflow.

[0032] like Figure 4-5 As shown, the through hole 9 gradually decreases in diameter as it approaches the water storage chamber 8, which can reduce the effect of the liquid inside escaping, thereby enhancing the water retention effect in the water storage chamber 8, and further allowing the liquid in the water storage chamber 8 to participate in heat transfer during the insulation process, thereby improving the insulation effect.

[0033] Structural principle:

[0034] When the water storage chamber 8 is in a waterless state, the temperature transfer inside the partition 4 will be disconnected in the water storage chamber 8, increasing the loss during heat transfer and reducing the impact on indoor temperature. After there is liquid in the water storage chamber 8, during the sun exposure, the carrier used to absorb heat and transfer temperature in the water storage chamber 8 will become water. The specific heat capacity of water is greater than that of the partition 4 material and air. The water in the water storage chamber 8 evaporates after absorbing heat, and the evaporation process will condense again, causing the temperature in the partition 4 to circulate, which can greatly increase the heat transfer loss in the partition 4 and achieve a good thermal insulation effect.

[0035] During rainfall, water flow is guided between the two partitions 4. Several protrusions 7 provided on the surface of the partition 4 can prevent the water flow from diffusing when it flows obliquely under the action of gravity. Several through holes 9 are provided on the surface of the partition 4, and the through holes 9 are connected to the water storage chamber 8. During the flow of water, it can enter the water storage chamber 8 from the through holes 9 for storage. After the water storage chamber 8 is filled with water, the excess water will flow downward under the guidance of the partition 4.

[0036] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
