Description

Technical Field

[0001] This utility model belongs to the field of support technology, specifically relating to a cup-shaped independent foundation and a support column connection assembly. Background Technology

[0002] For special purposes such as providing shade (bridges or roadbeds between tunnels), sound insulation (residential areas), and toll collection, steel-structured canopies are needed along highway transportation corridors. During construction, the supporting columns of the canopy (multiple columns arranged in rows along the canopy's extension) are situated on the highway's central median. Currently, the supporting columns are typically constructed using pile foundations. However, this method has several drawbacks: communication silicon core pipes are generally installed approximately 60cm below the ground surface of the central median. These horizontally distributed and numerous pipes can obstruct pile foundation construction, affecting efficiency and even preventing construction altogether due to the inability to avoid them. Furthermore, since the pile foundations are cast in-situ, inconsistencies in the pouring process can lead to uneven pile top elevations among the rows of piles, impacting the success rate and efficiency of their connection with the canopy's supporting beams. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a cup-shaped independent foundation and support column connection assembly to improve the convenience and efficiency of steel structure greenhouse support structure construction.

[0004] This utility model solves the above problems through the following technical means: a cup-shaped independent foundation and support column connection assembly, including a cup-shaped independent foundation, a support column, a column end flange and an adjustable flange, wherein a connecting bolt is fixedly installed inside the cup mouth of the cup-shaped independent foundation, the column end flange is fixedly connected to the bottom end of the support column, the top end of the connecting bolt passes through the mating column end flange and the adjustable flange, and is limited by nuts threadedly connected to the connecting bolt on the upper side of the column end flange and the lower side of the adjustable flange.

[0005] In implementing the above solution, based on the requirements of flange connection, the connecting bolts are arranged vertically at the bottom of the cup opening, with multiple bolts spaced circumferentially.

[0006] Furthermore, a fixed flange is pre-embedded in the cup-shaped independent foundation, and the bottom end of the connecting bolt passes through the fixed flange and is fixed on the upper and lower sides of the fixed flange by nuts that are threadedly connected to the connecting bolt.

[0007] Furthermore, the space formed by the lower part of the adjustable flange and the cup opening forms a first grouting zone, and the adjustable flange is provided with grouting holes for grouting into the first grouting zone.

[0008] Furthermore, the space enclosed by the support column and the cup mouth forms a second grouting zone.

[0009] Furthermore, the cup-shaped independent foundation, the fixing flange, and the connecting bolts are prefabricated as a single unit.

[0010] Furthermore, the support column and the column end flange are prefabricated as a single unit.

[0011] Furthermore, the support column is a cylinder.

[0012] Furthermore, the cup-shaped independent foundation is pre-embedded with bidirectional reinforcing steel bars.

[0013] Furthermore, the inner wall of the cup-shaped independent foundation is circumferentially spaced with vertical reinforcing bars, which are then wrapped with spiral hoops to form a reinforcing cage. This allows for the pouring of a concrete layer around the supporting column based on the reinforcing cage, thereby improving impact resistance.

[0014] The beneficial effects of this utility model are:

[0015] This utility model discloses a cup-shaped independent foundation and support column connection assembly, comprising a cup-shaped independent foundation, a support column, a column end flange, and an adjustable flange. A connecting bolt is fixedly installed inside the cup-shaped independent foundation. The column end flange is fixedly connected to the bottom end of the support column. The top of the connecting bolt passes through the mating column end flange and the adjustable flange, and is limited by nuts threaded to the connecting bolt on both the upper side of the column end flange and the lower side of the adjustable flange. The cup-shaped independent foundation and support column connection assembly of this application comprises a cup-shaped independent foundation and a support column assembled together. The cup-shaped independent foundation and support column can be prefabricated in advance, eliminating the need for on-site pouring. This facilitates easy excavation and installation on-site, ensuring quality and safety. Furthermore, based on the flange assembly method, the column top elevation can be finely adjusted, eliminating the influence of inconsistent column top elevations caused by the longitudinal and transverse slopes of the road surface. Therefore, it effectively improves the convenience and efficiency of steel structure greenhouse support structure construction. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more apparent. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0019] like Figure 1As shown, this embodiment provides a cup-shaped independent foundation and support column connection assembly, including a cup-shaped independent foundation 1, a support column 5, a column end flange 4, and an adjustable flange 3. A connecting bolt 2 is fixedly installed inside the cup-shaped independent foundation. In this embodiment, a fixed flange 9 is pre-embedded inside the cup-shaped independent foundation. The bottom end of the connecting bolt passes through the fixed flange and is fixed on the upper and lower sides of the fixed flange by nuts threaded to the connecting bolt. The column end flange is fixedly connected to the bottom end of the support column. The top end of the connecting bolt passes through the mating column end flange and the adjustable flange, and is limited on the upper side of the column end flange and the lower side of the adjustable flange by nuts threaded to the connecting bolt. In this embodiment, based on the flange connection requirements, the connecting bolts are arranged vertically at the bottom of the cup opening, with multiple bolts spaced circumferentially.

[0020] The cup-shaped independent foundation can be stepped or sloping. When constructed in the median strip of a highway, the bottom of the cup-shaped independent foundation is located above the silicon core tube group. The wide base section spans the silicon core tube group and can withstand the load transmitted from the column ends. The lower part of the silicon core tube group is high-compact, high-bearing-capacity subgrade soil, and the perimeter of the silicon core tubes is a cement-stabilized layer. The overall bearing capacity is strong and can meet the bearing capacity requirements of the cup-shaped independent foundation.

[0021] The space formed by the adjustable flange and the cup opening below it forms a first grouting zone 8, and the adjustable flange has grouting holes 7 for grouting into the first grouting zone. The space formed by the support column and the cup opening forms a second grouting zone 6.

[0022] The cup-shaped independent foundation, fixing flange, and connecting bolts are prefabricated as a single unit. The support column and column end flange are also prefabricated as a single unit. The support column can be a precast steel-concrete composite column or a precast PC column, preferably a precast steel-concrete composite column, as its fire resistance is superior to that of pure steel columns and reinforced concrete columns. If a precast steel-concrete composite column is damaged, the damaged section can be cut off and replaced with a new column section. The cut-off point is bonded with structural adhesive, and the external steel pipe is welded on. Construction is fast and quick.

[0023] In this embodiment, the support column is a cylinder, and correspondingly, the cup opening of the cup-shaped independent foundation is also a round cup opening.

[0024] Since the length of the precast support columns is fixed, and the top elevation of the precast columns is also fixed, while the elevation of the column base varies due to the influence of longitudinal and transverse slopes of the road surface, the elevation of the adjustable flange is adjusted by raising and lowering it (by rotating the nut on the lower side of the adjustable flange) to accommodate the length of the precast support columns. This ensures that the top elevation of the constructed support columns meets the design requirements, facilitating connection with the support beams of the greenhouse. The installation procedure for the support columns is as follows: Adjust the elevation of the adjustable flange, and fill the first grouting area with high-grade concrete or epoxy mortar. Hoist the precast support columns, align the column end flange with the adjustable flange and tighten the corresponding nuts, and then fill the second grouting area with high-grade concrete mortar or epoxy resin mortar.

[0025] After the support post protrudes from the road surface, it connects to the crash barrier. At this point, the circular support post may protrude from both sides of the crash barrier (i.e., the diameter of the post is larger than the thickness of the crash barrier). Because it is a circular post, the protruding surface is arc-shaped, preventing vehicle scraping and not affecting the crash barrier's impact resistance. The crash barrier and the circular support post work together to resist vehicle impacts without damage.

[0026] The cup-shaped independent foundation is pre-embedded with bidirectional reinforcing bars 10, which can be extended to increase the span of the cup-shaped independent foundation, or the bidirectional reinforcing bars can be anchored to the cement water-stabilized layer to enhance the impact resistance, pull-out resistance, wind resistance and earthquake resistance of the whole formed by the support column and the cup-shaped independent foundation.

[0027] Furthermore, the inner wall of the cup-shaped independent foundation is circumferentially spaced with vertical reinforcing bars, which are then wrapped with spiral hoops to form a reinforcing cage. This allows for the pouring of a concrete layer around the supporting column based on the reinforcing cage, thereby improving impact resistance.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
