Description

Technical Field

[0001] This utility model belongs to the field of building technology in frigid regions, and relates to a thermal insulation system for elevated buildings in frigid regions, and more particularly to a thermal insulation system for a wooden elevated platform in frigid regions. Background Technology

[0002] For buildings, the column base connects the main load-bearing column to the foundation, transferring the bending moment, axial force, and shear force of the load-bearing column to the foundation. It is a critical node related to structural safety and requires a reliable connection.

[0003] For elevated buildings in permafrost regions, the Arctic and Antarctic, and other frigid areas, heat transfer occurs between the interior and exterior, between the interior and the foundation, and at grounded column bases, because outdoor air and base temperatures are often much lower than indoor operating temperatures. Due to grounding requirements, the column bases penetrate the building's overall insulation. Without effective insulation measures, the insulation effect is reduced when using traditional steel-structured elevated platforms, leading to increased energy consumption, large temperature fluctuations in localized areas, and even condensation and icing.

[0004] Given the technical deficiencies of existing technologies, there is an urgent need for a thermal insulation system suitable for elevated buildings in frigid regions. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a heat insulation system for wooden elevated platforms in extremely cold regions, which can achieve good heat insulation effect, and is simple to construct, easy to transport and replace components.

[0016] Compared with existing technologies, the thermal insulation system for wooden elevated platforms in frigid regions of this utility model has one or more of the following beneficial technical effects: 1. This utility model uses a wooden structure elevated platform to replace the conventional steel structure elevated platform. The steel columns of the upper building are connected to the foundation inserted into the permafrost through the wooden structure elevated platform.

[0035] In this utility model, a wooden elevated platform replaces the conventional steel elevated platform, and the steel columns 6 of the upper building are connected to the foundation 2 buried in permafrost via the wooden elevated platform. For example, Figure 1 and 2 As shown, the timber-framed elevated platform includes timber columns 3, timber platform beams 4, and timber supports 5. The timber-framed elevated platform can be made of oak, mahogany, birch, red oak, hard maple, alder, beech, boxwood, etc., which are dense, hard, and have strong load-bearing capacity.

[0036] The upper structure, via a simple node connection to the wooden elevated platform, provides thermal insulation at the column bases of the steel columns. Simultaneously, the upper load is reliably transferred to the foundation 2 through the wooden elevated platform. The connection between the wooden columns 3 and the foundation 2 can be rigid, semi-rigid, or hinged. The connection between the wooden platform beam 4 and the wooden columns 3 can be hinged, forming a lateral force resisting system through the addition of bidirectional wooden supports 5. The number of wooden supports 5 can be adjusted according to the actual layout. The vertical load from the upper structure is borne by the wooden columns 3, and the horizontal load is borne by the wooden supports 5.

[0037] The following is for reference. Figure 1-2 This invention provides a detailed description of a thermal insulation system for a wooden elevated platform in frigid regions. The system comprises an outdoor foundation 2 embedded in the ground 1, a wooden elevated platform, and steel columns 6 of the building. The wooden elevated platform includes wooden columns 3, wooden platform beams 4, and wooden supports 5.

[0038] The top of the foundation 2 is connected to the bottom of the wooden column 3.

[0039] In this invention, the foundation 2 can be pre-embedded in the ground (e.g., permafrost) 1. Preferably, the foundation 2 is a concrete foundation, which serves a supporting function.

[0040] Meanwhile, the connection between the top of the foundation 2 and the bottom of the wooden column 3 can be a rigid connection, a semi-rigid connection, or a hinged connection.

[0041] like Figure 7 and 8 As shown, when using a rigid or semi-rigid connection, a connecting steel sleeve 15 with an upward opening is pre-embedded at the top of the foundation 2. The connecting steel sleeve 15 is U-shaped, and the bottom end of the wooden structure column 3 is inserted into the connecting steel sleeve 15. The top end of the foundation 2 is connected to the bottom end of the wooden structure column 3 by a second connecting bolt 16 passing through the connecting steel sleeve 15 and the bottom end of the wooden structure column 3.

[0042] like Figure 9 and 10 As shown, when using a hinged connection, a cross-shaped connecting plate 17 extending upwards is pre-embedded at the top of the foundation 2. The cross-shaped connecting plate 17 is inserted into the bottom of the wooden column 3. The top of the foundation 2 is connected to the bottom of the wooden column 3 by a second connecting bolt 16 passing through the bottom of the wooden column 3 and the cross-shaped connecting plate 17.

[0043] The upper end of the wooden structure column 3 is connected to one end of the wooden structure platform beam 4, and the wooden structure support 5 is arranged between the adjacent wooden structure column 3 and the wooden structure platform beam 4 connected to the adjacent wooden structure column 3.

[0044] In this utility model, the connection between the wooden platform beam 4 and the wooden column 3 can be a hinged connection. Specifically, as shown... Figure 11-13 As shown, a steel connecting plate 18 is provided on the outer side of the upper end of the wooden structure column 3. Alternatively, a U-shaped steel connecting sleeve can be directly fitted onto the outer side of the upper end of the wooden structure column 3. The steel connecting plate 18 is connected to the upper end of the wooden structure column 3 by a third connecting bolt 19 passing through the steel connecting plate 18 and the upper end of the wooden structure column 3.

[0045] Meanwhile, a steel connector 21 is provided on the outer side of the steel connecting plate 18. The steel connector 21 is inserted into one end of the wooden platform beam 4. One end of the wooden platform beam 4 and the steel connector 21 are connected by a fourth connecting bolt 20 passing through one end of the wooden platform beam 4 and the steel connector 21. Thus, the upper end of the wooden column 3 is connected to one end of the wooden platform beam 4.

[0046] Among them, such as Figure 12 As shown, when all four sides of the wooden structure column 3 need to be connected to the wooden structure platform beam 4, a steel connector 21 is provided on each of the four sides of the steel connecting plate 18. One steel connector 21 is inserted into one end of each of the four wooden structure platform beams 4. This achieves the connection between the four wooden structure platform beams 4 and the wooden structure column 3.

[0047] like Figure 13 As shown, when the wooden column 3 only needs to be connected to the wooden platform beam 4 on both sides, only one steel connector 21 needs to be provided on each side of the steel connecting plate 18. One steel connector 21 is inserted into one end of each of the two wooden platform beams 4. This achieves the connection between the two wooden platform beams 4 and the wooden column 3.

[0048] At the location where the wooden structure support 5 is installed, in order to achieve the connection between the wooden structure support 5 and the wooden structure column 3 and the wooden structure platform beam 4, as follows: Figure 14 As shown, the steel connector 21 can be enlarged and extended beyond the wooden platform beam 4. The enlarged portion of the steel connector 21 extending beyond the wooden platform beam 4 is inserted into one end of the wooden support 5. One end of the wooden support 5 is connected to the steel connector 21 by a fifth connecting bolt 22 passing through one end of the wooden support 5 and the steel connector 21. This achieves the connection between the wooden support 5 and the wooden column 3 and the wooden platform beam 4.

[0049] In this invention, preferably, the steel connector 21 and the steel connecting plate 18 are integrally formed. This enhances the connection strength and reduces some connection operations.

[0050] The bottom end of the steel column 6 is connected to the top end of the wooden structure column 3.

[0051] In this utility model, the connection between the bottom end of the steel column 6 and the top end of the wooden structure column 3 can be achieved in a variety of different ways.

[0052] in, Figure 3 A longitudinal sectional view is shown at the connection point between the bottom of a steel column and the top of a timber column, illustrating one possible connection method. (See attached image.) Figure 3 As shown, the wooden column 3 is equipped with pre-installed anchor bolts 9. The steel column 6 is connected to the lower steel beam 8 of the building, and its lower end extends out of the building from the lower steel beam 8. The lower end of the steel column 6 is provided with a column base plate 11, and the column base plate 11 is a certain distance away from the very end of the steel column 6. Thus, the top end of the wooden column 3 can be inserted into the bottom end of the steel column 6 and abut against the column base plate 11. Then, the bottom end of the steel column 6 is connected to the top end of the wooden column 3 by the pre-installed anchor bolts 9 and nuts 10 passing through the column base plate 11.

[0053] Figure 4 A longitudinal sectional view is shown at the connection point between the bottom of a steel column and the top of a timber column, illustrating an alternative connection method. (See attached image.) Figure 4As shown, the bottom end of the steel column 6 is connected to the top end of the wooden column 3 via a connecting sleeve 12 with a transverse partition in the middle. The wooden column 3 is equipped with pre-installed anchor bolts 9. The steel column 6 is connected to the lower steel beam 8 of the building, and its lower end extends out of the building from the lower steel beam 8. The steel column 6 has a base plate at its very end. The top end of the wooden column 3 is inserted into the lower end of the connecting sleeve 12 with the transverse partition in the middle and abuts against the lower surface of the transverse partition. The bottom end of the steel column 6 is inserted into the upper end of the connecting sleeve 12 and abuts against the upper surface of the transverse partition. The bottom end of the steel column 6 is connected to the top end of the wooden column 3 by the pre-installed anchor bolts 9 and nuts 10 passing through the base plate of the steel column 6 and the transverse partition.

[0054] Figure 5 This shows a longitudinal sectional view of the connection between the bottom of a steel column and the top of a timber column, representing another type of connection. (See attached image.) Figure 5 and 6 As shown, the steel column 6 is connected to the lower steel beam 8 of the building, and its bottom end is flush with the lower steel beam 8. A cross-shaped steel plate 13 is provided at the bottom end of the steel column 6, and the cross-shaped steel plate 13 extends outside the building. The cross-shaped steel plate 13 is inserted into the top of the wooden structure column 3. The bottom end of the steel column 6 is connected to the top end of the wooden structure column 3 by a first connecting bolt 14 that passes laterally through the top end of the wooden structure column 3 and the cross-shaped steel plate 13.

[0055] Since the thermal conductivity of wood is much lower than that of steel, wood can be used as a heat insulation material. In this invention, no additional heat insulation material is needed between the steel column 6 and the wooden column 3, that is, at the traditional column base, making the connection of the heat insulation node simpler.

[0056] Thermal insulation material 7 is provided on the outside of the connection between the steel column 6 and the wooden structure column 3.

[0057] like Figure 3-5 As shown, thermal insulation material 7 is installed on the outside of the connection between the steel column 6 and the wooden structure column 3. By installing the thermal insulation material 7, heat transfer between the steel column 6 and the outdoor atmosphere can be reduced, further ensuring the thermal insulation effect.

[0058] As described above, in this utility model, the entire construction process adopts steel connectors and bolt connections, forming a fully prefabricated structure. All components are prefabricated, eliminating any wet work or welding on-site, thus simplifying construction. Furthermore, since wood has a much lower density than steel structures, it is particularly convenient for transport, especially in polar regions. Moreover, due to the "assembly" nature of the wood structure connections, components can be replaced when necessary.

[0059] To demonstrate the effectiveness of this utility model's thermal insulation system for wooden elevated platforms in frigid regions, the inventors... Figure 3 Taking the connection method shown as an example, the insulation effects of the wooden structure elevated platform insulation system of this utility model in cold regions and the wooden structure elevated platform insulation system of this utility model in cold regions without the use of this utility model (i.e., using a traditional steel structure elevated platform) were calculated. In the calculation, the heat transfer difference between the wooden structure elevated platform of this utility model and the traditional steel structure elevated platform (neither with other insulation measures) was mainly compared under the same indoor and outdoor environment and the same cross-sectional dimensions.

[0060] The various dimensions of steel column 6, the height of the connecting section, and the comprehensive calculation results are shown in the table below.

[0061] As shown in the table above, under the same conditions, the heat transfer of a steel structure platform is 152.05W, while that of a wooden structure platform is 5.65W, making the steel structure platform approximately 26.9 times more efficient than the wooden structure platform. Therefore, the wooden structure elevated platform insulation system for frigid regions described in this invention eliminates the need for additional insulation materials between the steel columns of the upper building and the wooden structure elevated platform; a good insulation effect can be achieved through simple node connections.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit the scope of protection of this utility model. Those skilled in the art can modify or make equivalent substitutions to the technical solution of this utility model based on the concept of this utility model, without departing from the essence and scope of the technical solution of this utility model.
