Description

Technical Field

[0001] This invention belongs to the field of building support technology, and in particular relates to a building support structure applicable to hillside terrain. Background Technology

[0002] With the development of tourism, the demand for buildings such as homestays and hotels is gradually increasing. For some mountainous scenic areas, many buildings need to be built directly on the hillside. Since hillsides are different from buildings on normal flat land, their stability support is particularly important.

[0003] For landscape buildings constructed on hillsides, in the early stages of construction design, it is necessary to select a suitable building location using GPS and on-site surveys, and to design a building model using BIM technology so that the completed building meets the usage requirements. However, traditional hillside construction requires leveling the slope at a suitable location and driving deep pile foundations there. The subsequent foundations of the buildings and the buildings on the ground are all stabilized on the hillside by the pile foundations. However, due to the sloping terrain, the use of large pile drivers is greatly restricted, construction is relatively inconvenient, and the overall construction period is long. At the same time, due to the erosion of soil and water on the slope, the bottom of the pile foundation is prone to become cavitary, which is detrimental to the safety of the building. Therefore, we propose a building support structure for hillside terrain to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a building support structure applicable to hillside terrain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a building support structure applied to hillside terrain, comprising a hillside and a building, wherein a building platform is provided on the hillside and the hillside is divided into an upper slope and a lower slope by the building platform, and a foundation pit is excavated on the building platform, wherein a foundation is constructed inside the foundation pit, and the building is located on the foundation, wherein steel columns are installed at both ends of the foundation near the upper slope, and two first concrete layers corresponding to the positions of the steel columns are buried on one side of the upper slope, wherein multiple first anchor members are connected to the upper slope through the first concrete layers, and multiple second anchor members are provided on the first concrete layers, and each second anchor member is fixed with a cable-stayed cable to the steel column on the same side, wherein multiple horizontal grooves are opened on the side wall of the lower slope near the upper side of the building, and each horizontal groove is inserted with a precast concrete column, and multiple sets of connecting holes are opened at the bottom of the foundation pit near the lower slope, and each connecting hole is filled with a cast-in-place concrete column.

[0006] In the above-mentioned building support structure applied to hillside terrain, multiple planting troughs are provided on both the upper and lower slopes, and each planting trough is lined with an ecological bag.

[0007] In the above-mentioned building support structure applied to hillside terrain, a second concrete layer is laid at the bottom of the foundation pit below the foundation. Multiple foundation trenches are excavated at the bottom of the foundation pit near the upslope side. Each foundation trench is equipped with a U-shaped anchor rod, which is anchored to the second concrete layer. The foundation trench is filled with concrete.

[0008] In the above-mentioned building support structure applied to hillside terrain, an installation groove is dug above multiple planting troughs on the same side of the upslope surface. The installation groove is V-shaped and the interior of the installation groove is lined with concrete guide strips.

[0009] In the above-mentioned building support structure applied to hillside terrain, a vertically arranged first insertion groove is excavated on the upper slope near the building side, and the interior of the first insertion groove is filled with a first reinforced concrete slab, which is perpendicular to the upper slope.

[0010] In the above-mentioned building support structure applied to hillside terrain, a vertically arranged second insertion groove is excavated at the position below multiple horizontal grooves on the lower slope surface, and the interior of the second insertion groove is filled with a second reinforced concrete slab.

[0011] In the aforementioned building support structure applied to hillside terrain, both steel columns are connected to the building by multiple steel structural frames.

[0012] In the aforementioned building support structure applied to hillside terrain, each of the cast-in-place concrete columns is 1 meter long.

[0013] Compared with existing technologies, the advantages of a building support structure applied to hillside terrain are:

[0014] 1. Buildings can be constructed using a set building platform, foundation pit, and foundation. By coordinating steel columns, a first concrete layer, a first anchor rod, a second anchor rod, and stay cables on the upper slope side of the hillside, the hillside above the building can be utilized for diagonal support using multi-point anchoring and diagonal cable. On the lower slope side, by coordinating horizontal trenches, precast concrete columns, and cast-in-place concrete columns, a support structure can be set up from the lower slope side to achieve stable support for the hillside terrain. This construction method eliminates the need for traditional deep foundation pits and pile foundations, reducing construction difficulty, the need for large equipment, and shortening the construction period. It is also less affected by cavities caused by rainwater settlement at the bottom of the hillside.

[0015] 2. By using multiple planting troughs and ecological bags in combination, it is easy to plant greenery on the slopes on both sides of the building, which can not only improve the aesthetics of the landscape, but also prevent horizontal water loss from the slope.

[0016] 3. Through the coordinated arrangement of the first interlocking groove, the first reinforced concrete slab, the second interlocking groove, and the second reinforced concrete slab, lateral support can be provided for the uphill and downhill surfaces, minimizing the impact of soil erosion and settlement on the safety of the building.

[0023] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0024] Example 1:

[0025] like Figure 1-5As shown, a building support structure for hillside terrain includes a hillside 1 and a building 2. A building platform 3 is provided on the hillside 1, dividing it into an upper slope 4 and a lower slope 5. A foundation pit 6 is excavated on the building platform 3, and a foundation 7 is constructed inside the foundation pit 6. The building 2 is located on the foundation 7. Steel columns 8 are installed at both ends of the foundation 7 near the upper slope 4. Two first concrete layers 9, corresponding to the positions of the steel columns 8, are embedded on one side of the upper slope 4. The first concrete layers 9 are connected to the upper slope... Multiple first anchor members 10 are connected together between 4. Multiple second anchor members 11 are provided on the first concrete layer 9. Each second anchor member 11 and the steel column 8 on the same side are jointly fixed with a cable 12. Multiple horizontal grooves 13 are opened on the side wall of the lower slope surface 5 near the upper side of the building 2. Each horizontal groove 13 is inserted into the interior of a precast concrete column 14. Multiple sets of connecting holes are opened on the bottom of the pit 6 near the lower slope surface 5. Each connecting hole is filled with a cast-in-place concrete column 15.

[0026] At the bottom of the foundation pit 6, below the foundation 7, a second concrete layer 18 is laid. Multiple foundation trenches 19 are excavated at the bottom of the foundation pit 6 near the upper slope 4. Each foundation trench 19 is equipped with a U-shaped anchor rod 20, which is anchored to the second concrete layer 18. The foundation trench 19 is filled with concrete. This arrangement can improve the connection stability between the foundation 7 and the hillside 1. After the concrete is poured through the U-shaped anchor rod 20, the U-shaped anchor rod 20 can penetrate the concrete, resulting in high connection strength.

[0027] Both steel columns 8 are connected to the building 2 by multiple steel structural frames 27, which can improve the connection strength between the steel columns 8 and the building 2.

[0028] Each cast-in-place concrete column 15 is set to a length of 1 meter, ensuring support strength without the need for excessive excavation depth.

[0029] Example 2:

[0030] Multiple planting troughs 16 are provided on both the upper slope 4 and the lower slope 5. Each planting trough 16 is lined with an ecological bag 17. Suitable plants can be planted in the ecological bag 17, which can not only enhance the aesthetics around the building 2, but also improve the protection against soil erosion on the hillside 1.

[0031] An installation trench 21 is dug on the upper slope 4 above multiple planting troughs 16 on the same side. The installation trench 21 is V-shaped and has concrete guide strips 22 laid inside. This design can guide the water flowing down the hillside and make it flow out from both sides of the building 2, reducing the impact of water on the hillside 1.

[0032] Example 3:

[0033] A vertically arranged first insertion groove 23 is excavated on the side of the upslope 4 near the building 2, and the inside of the first insertion groove 23 is filled with a first reinforced concrete slab 24. The first reinforced concrete slab 24 is arranged perpendicular to the upslope 4, which can bear the soil pressure from one side of the upslope 4, prevent the soil layer from being moved down by the flow of water, and reduce the risk of collapse.

[0034] A vertically arranged second insertion groove 25 is excavated at the position below the multiple horizontal trenches 13 on the downslope surface 5, and the interior of the second insertion groove 25 is filled with a second reinforced concrete slab 26, which can bear the soil pressure from one side of the downslope surface 5, prevent the soil layer from being moved downward by the flow of water, and reduce the risk of collapse.

[0035] The operating principle of this invention is described as follows: After designing a suitable building at a suitable location on a hillside 1 using GPS and BIM technologies, a building platform 3 and a foundation pit 6 are excavated at the selected location. Then, multiple horizontal trenches 13 are horizontally excavated at a suitable location on the lower slope 5, and multiple precast concrete columns 14 are inserted into them. Then, multiple connecting holes are excavated at the bottom of the foundation pit 6, and cast-in-place concrete columns 15 are poured during this period to connect with the precast concrete columns 14. Then, a foundation 7 is constructed in the foundation pit 6, and a building 2 is constructed on the foundation 7. During the pouring of the foundation 7, steel columns 8 are embedded at positions located on both sides of the building 2. Then, a suitable location is selected, and a foundation is excavated at the upper slope 4. The first concrete layer 9 is poured and anchored to the upper slope surface 4 by the first anchor rod 10, and multiple second anchors 11 are reserved. Then, multiple stay cables 12 are inclined between the multiple second anchors 11 and the steel column 8 on the same side. The stay cables 12 are used to transfer the stress of the building to the first concrete layer 9 and support the upper side of the building through the upper slope surface 4. The building can be supported from the lower slope side by precast concrete columns 14 and cast-in-place concrete columns 15. This construction method does not require the processing of traditional deep foundation pits, reduces the construction difficulty, reduces the need for large equipment, shortens the construction period, and is less affected by the voids caused by rainwater settlement at the bottom of the hillside.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
