Description

Technical Field

[0001] This utility model belongs to the field of ice building construction technology, specifically relating to a prefabricated ice building interior ceiling structure. Background Technology

[0002] Existing ice structure roof designs and construction methods primarily rely on masonry, often using the thick structure of ice blocks directly as the load-bearing structure of the entire building. There is a lack of specific roof insulation measures for ice structures. Current roof insulation measures are mainly for ordinary reinforced concrete structures, typically involving laying insulation layers and reflective films to improve the insulation performance of residential buildings. While these measures are effective for the insulation performance of ordinary buildings, for ice structures, the reason is that the ice sheets to which the reflective film is directly attached have a low temperature. In low-temperature environments, the material properties of the reflective film may undergo changes such as embrittlement and shrinkage, thus affecting its thermal insulation effect. Therefore, developing a prefabricated ice building interior roof structure to improve the insulation performance of ice building interior roofs is highly practical. Utility Model Content

[0003] This utility model aims to solve the problem that existing indoor roof insulation measures are not effective in insulating the interior ceiling of ice building structures, and thus provides a prefabricated ice building interior ceiling structure.

[0004] An interior ceiling structure for a prefabricated ice building includes an insulation board, a cast ice board, and N connecting nails, where N is a positive integer. The cast ice board is laid on top of the insulation board and is fastened to the insulation board by the N connecting nails.

[0005] Furthermore, the bottom of the heat insulation board is evenly processed with N heat insulation board through holes, and the bottom of the cast ice board is evenly processed with N ice surface through holes. Each ice surface through hole on each cast ice board is coaxially corresponding to one heat insulation board through hole on the heat insulation board. Each connecting nail is inserted from bottom to top into a corresponding set of heat insulation board through holes and ice surface through holes. The limiting part of each connecting nail is set at the bottom of the heat insulation board, and the connecting part of each connecting nail is fixedly connected to the cast ice board.

[0006] Furthermore, the space between each connecting nail and the wall of the hole in the ice surface is filled with ice powder mixed with water, and each connecting nail is fixed to the ice plate by the corresponding ice powder mixed with water filling material.

[0007] Furthermore, the connecting nail includes a limiting plate and a vertical nail body. The vertical nail body is fixed to the top center of the limiting plate, and the axis of the vertical nail body is collinear with the axis of the limiting plate. The limiting plate is located below the heat insulation plate. The vertical nail body passes through the heat insulation plate and is inserted into a corresponding ice surface through hole. The vertical nail body is fixed to the poured ice plate by ice powder mixed with water filler.

[0008] Furthermore, the length h2 of the vertical nail is smaller than the depth of the through hole in the ice surface;

[0009] Furthermore, the connecting nail also includes a traction wire, which is located at the top of the vertical nail body, and one end of the traction wire is fixedly connected to the top of the vertical nail body.

[0010] Furthermore, the insulation board is made of PC endurance board;

[0011] Furthermore, the hole spacing between two adjacent through holes in the insulation board is 300-500mm, the end face diameter of the through hole is 20-60mm, the distance between the through hole at the edge and the edge of the insulation board is greater than 100mm, the thickness of the insulation board is 30-150mm, the length is 1750-2500mm, and the width is 500-800mm.

[0012] Furthermore, the thickness of the ice plate is 150-450mm, the length is 1750-2500mm, the width is 500-800mm, the end face diameter of the ice surface through hole is 30-80mm, and the end face diameter of the ice surface through hole is 3mm larger than the end face diameter of the insulation board through hole.

[0014] The beneficial effects of this application compared to the prior art are:

[0015] This application provides an innovative prefabricated ice building interior ceiling structure, which combines a PC endurance board and a cast ice board. The addition of connecting studs to the ceiling structure improves the overall strength and toughness of the connection between the insulated PC endurance board and the ice board, creating a stable load-bearing structure. This results in more stable performance of the multi-functional combined ice board under load. The PC endurance board used has a simple design and minimal impact on the performance of the ice board during assembly, making it widely applicable to various types of ceiling structures. Addressing the material characteristics of ice materials, such as their tendency to freeze and bond easily, an innovative method of using insulated connecting studs is employed. A mixture of crushed ice and water is used to fill the gaps between the connecting studs and the ice board, effectively ensuring the connection performance. The connecting studs are made of FRP, nylon, and other thermal insulation materials, providing an effective connection to the PC board while preventing thermal bridging caused by the connecting studs connecting the two sides of the ice board, thus ensuring the overall thermal insulation performance of the multi-functional combined ice board and achieving good insulation performance.

[0032] The prefabricated ice building interior ceiling structure provided in this embodiment, compared with the insulation design of traditional buildings, fixes the insulation PC endurance board to the bottom surface of the ice board by setting connecting nails. It effectively utilizes the advantage of the ice structure being easy to solidify and assemble. At the same time, considering that the ice structure is difficult to bond and combine with the insulation board, the innovative nail-based insulation structure is proposed, providing a feasible method for enhancing the performance of the interior wall panels of ice buildings and for heat insulation construction.

[0033] Specific Implementation Method Two: Combining Figures 1 to 6 This embodiment differs from specific embodiment one in that the bottom of the heat insulation plate 1 has N heat insulation plate through holes 11 evenly distributed, and the bottom of the cast ice plate 2 has N ice surface through holes 21 evenly distributed. Each ice surface through hole 21 on the cast ice plate 2 is coaxially corresponding to one heat insulation plate through hole 11 on the heat insulation plate 1. Each connecting nail 3 is inserted from bottom to top into a corresponding set of heat insulation plate through holes 11 and ice surface through holes 21. The limiting part of each connecting nail 3 is located at the bottom of the heat insulation plate 1, and the connecting part of each connecting nail 3 is fixedly connected to the cast ice plate 2. Other components and connection methods are the same as in specific embodiment one.

[0034] Specific implementation method three: Combining Figures 1 to 6 This embodiment differs from Specific Embodiment Two in that the space between each connecting nail 3 and the wall of the through hole 21 on the ice surface is filled with ice powder mixed with water filler 4, and each connecting nail 3 is frozen and fixed to the cast ice plate 2 by the corresponding ice powder mixed with water filler 4. Other components and connection methods are the same as in Specific Embodiment Two.

[0035] In this embodiment, ice powder mixed with water filler 4 is used as a medium. The ice materials freeze and bond with each other, which is easy to bond. The connecting nail 3 and the cast ice plate 2 are frozen and fixed, which simplifies the connection structure and reduces the connection cost.

[0036] Specific implementation method four: Combination Figures 1 to 6 This embodiment differs from specific embodiment three in that the connecting nail 3 includes a limiting plate 31 and a vertical nail body 32. The vertical nail body 32 is fixed to the top center of the limiting plate 31, and the axis of the vertical nail body 32 is collinear with the axis of the limiting plate 31. The limiting plate 31 is located below the heat insulation plate 1. The vertical nail body 32 passes through the heat insulation plate 1 and is inserted into an ice surface through hole 21. The vertical nail body 32 is frozen and fixed to the cast ice plate 2 by ice powder mixed with water filler 4. Other components and connection methods are the same as in specific embodiment three.

[0037] Specific Implementation Method Five: Combining Figures 1 to 6 This embodiment differs from Specific Embodiment Four in that the length h2 of the vertical nail body 32 is smaller than the depth of the ice surface through hole 21. Other components and connection methods are the same as in Specific Embodiment Four.

[0038] In conjunction with the descriptions of specific embodiments four and five, the connecting nail 3 is an important connecting component in this application. Its material is nylon or other heat-insulating materials. The limiting plate 31 is used to support the heat insulation plate 1, and the vertical nail body 32 is used to connect the heat insulation plate 1 and the ice-casting plate 2 in series and to achieve freezing and fixing with the ice-casting plate 2 by cooperating with the ice powder mixed with water filler 4.

[0039] Specific Implementation Method Six: Combination Figures 1 to 6 This embodiment differs from Specific Embodiment Five in that the connecting nail 3 further includes a traction wire 33. The traction wire 33 is located at the top of the vertical nail body 32, and one end of the traction wire 33 is fixedly connected to the top end of the vertical nail body 32. Other components and connection methods are the same as in Specific Embodiment Five.

[0040] In this embodiment, the traction line 33 is mainly used to pull and position the connecting nail 3. One end of the line is fixedly connected to the vertical nail body 32, and the other end extends to the outside of the ice surface through hole 21 and is wrapped and bound to the pre-set positioning structure. Under the longitudinal traction state of the traction line 33, the limiting plate 31 can be kept in close contact with the heat insulation plate 1, and the connection between the connecting nail 3, the ice pouring plate 2 and the heat insulation plate 1 is also made closer, so that when the ice powder mixed with water filler 4 is injected into the ice surface through hole 21, the position of the connecting nail 3 can remain unchanged.

Other components and connection methods are the same as in specific embodiment seven.

[0043] Specific Implementation Method Nine: Combining Figures 1 to 6 This embodiment differs from Specific Embodiment Eight in that the thickness of the cast ice plate 2 is 150–450 mm, the length is 1750–2500 mm, the width is 500–800 mm, and the end face diameter of the ice surface through hole 21 is 30–80 mm, which is 3 mm larger than the end face diameter of the insulation plate through hole 11. Other components and connection methods are the same as in Specific Embodiment Eight.

[0044] In this embodiment, the end face diameter of the ice surface through hole 21 is larger than the end face diameter of the heat insulation plate through hole 11 so that the connecting nail 3 can be circumferentially wrapped when the ice powder mixed with water filler 4 is filled, thereby increasing the filling range of the ice powder mixed with water filler 4 and also improving the tightness of the freezing fixation between the connecting nail 3 and the cast ice plate 2.

[0046] The present invention has been disclosed above with reference to preferred embodiments, but it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.

[0047] Working principle:

[0048] The prefabricated ice building interior ceiling structure provided in this application is fabricated through the following steps:

[0049] Step 1: Select a suitable PC endurance board according to the size requirements of the ceiling and cut it to obtain the heat insulation board 1. Then, process multiple heat insulation board through holes 11 on the heat insulation board 1 according to the pre-design. After all the heat insulation board through holes 11 are processed, set them aside for use.

[0050] Step 2: Prepare the ice plate 2 according to the size of the ceiling. The ice plate 2 is cast in layers. The thickness of each layer does not exceed 10mm. In order to facilitate the subsequent movement and installation of the ice plate 2, lifting rods for hoisting are pre-embedded on both sides of the ice plate during the preparation of the ice plate 2.

[0051] Step 3: Drill holes in the ice plate 2 prepared in Step 2. Use the PC endurance board in-situ laying method to locate the drilling position of the ice surface through hole 21. Use a wooden drill to drill through the ice plate 2. The hole diameter should not be less than 3mm of the end face diameter of the connecting nail 3.

[0052] Step 4: Invert multiple connecting nails 3 on the support platform, first put the heat insulation board 1 on the multiple connecting nails 3, and then hoist the ice plate 2 to the top of the heat insulation board 1, ensuring that the vertical nail body 32 in each connecting nail 3 passes through the heat insulation board 1 and is inserted into the ice plate 2 in sequence.

[0053] Step 5: Extend the traction rope 33 at the end of each connecting nail 3 out of the outside of the ice-casting plate 2, and wrap and bind it to the horizontal baffle 5 placed on the top of the ice-casting plate 2. The horizontal baffle 5 has a through hole in the middle for injecting ice powder mixed with water filler 4. At the same time, the horizontal baffle 5 also has a certain weight. After the traction rope 33 is wrapped and bound, it can exert a certain pulling and positioning effect on the connecting nail 3, ensuring that the connecting nail 3 is more tightly connected to the ice-casting plate 2 and the heat insulation plate 1.

[0054] Step 6: Inject the ice powder mixed with water filler 4 into the ice surface through hole 21 through the through hole in the horizontal baffle 5 until the ice powder mixed with water filler 4 fills the ice surface through hole 21. Let it stand for 6 hours to freeze, so that the connecting nail 3 and the ice plate 2 are frozen and fixed.

[0055] Step 7: After the ceiling structure is frozen and fixed, release the end of the traction line 33 and remove the horizontal baffle 5 used for temporary fixation. Cut the traction line 33 that extends beyond the poured ice plate 2 to obtain the complete indoor ceiling structure.
