Description

Technical Field

[0001] This utility model relates to the field of building foundation technology, and in particular to a corbel column for a shallow, dark pond independent foundation that is deeply buried. Background Technology

[0002] During the factory construction process, foundation exploration revealed shallow, dark ponds, necessitating design changes to the foundation. Conventional practices (such as...) Figure 4 (As shown): For isolated foundations with hidden ponds, deep foundations are adopted, and the pile cap is enlarged by 100mm on each side. Strip foundations are cancelled at locations with hidden ponds. Foundation connecting beams are set at -0.060, extending one span on each side towards the shallow foundation. The column cross-section is enlarged by 240mm, and reinforcement is increased.

[0003] The stability of a deep-buried foundation can be ensured by increasing the number of columns on top of the existing deep-buried columns. However, the increased columns need to be connected to the deep-buried foundation, and then foundation connecting beams need to be added on the increased columns. This increases the volume of concrete required, which in turn increases the project cost. Summary of the Invention

[0004] The purpose of this utility model is to provide a corbel column for a shallow, dark pond with an independent foundation that is deeply buried, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corbel column for a shallow, dark pond with an independent foundation, comprising a deep-buried foundation, a deep-buried column cast on top of the deep-buried foundation, and a corbel column set on one side of the deep-buried column, the corbel column and the deep-buried column being integrally cast from concrete, the corbel column and the deep-buried column being internally reinforced with steel bars, and the corbel column and the deep-buried column being provided with connecting reinforcement components for strengthening the connection on their sides;

[0006] The steel reinforcement support includes main reinforcing bars of the corbel column inserted inside the corbel column, and multiple hooked reinforcing bars are provided between the main reinforcing bars of the corbel column. The main reinforcing bars of the corbel column and the hooked reinforcing bars are fixed by binding.

[0007] Preferably, the steel reinforcement support further includes main steel bars inserted into the deeply embedded column, and main horizontal steel bars are evenly distributed at equal intervals between the main steel bars.

[0008] Preferably, the main horizontal reinforcing bars that match the height of the corbel column are welded to the hook reinforcing bars, and the main reinforcing bars of the column and the main horizontal reinforcing bars are fixed by binding.

[0009] Preferably, the connection reinforcement assembly includes supports respectively installed on the sides of the corbel column and the buried column, and the supports are L-shaped structures.

[0010] Preferably, expansion bolts are installed at the connection between the support and the corbel and the buried column, and the expansion bolts are inserted into the interior of the corbel and the buried column.

[0011] Preferably, a connecting bolt is installed on the top of the support, and a reinforcing steel wire rope is threaded through a pin hole on the top of the connecting bolt.

[0012] Preferably, the bottom plane of the corbel surface of the corbel column is on the same horizontal plane as the bottom plane of the existing foundation connecting beam.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By replacing the original enlarged columns and foundation connecting beams with corbel columns, the amount of concrete used is greatly reduced, thereby reducing the project cost. Furthermore, since the corbel columns are supported by bent steel bars, the connection stability between the corbel columns and the deeply buried columns can be increased, ensuring that the corbel columns can be used normally.

[0015] 2. The reinforced steel wire rope can pull the corbel column from above, making the connection between the corbel column and the deep-buried column stronger. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution:

[0025] Please see Figures 1 to 4 A type of corbel column for a shallow, dark pond with an independent foundation, comprising a deep-buried foundation 1, a deep-buried column 2 cast on top of the deep-buried foundation 1, and a corbel column 3 set on one side of the deep-buried column 2. The corbel column 3 and the deep-buried column 2 are cast in one piece of concrete. The corbel column 3 and the deep-buried column 2 are provided with steel reinforcement 5 inside, and the corbel column 3 and the deep-buried column 2 are provided with connecting reinforcement components 4 for strengthening the connection on their sides.

[0026] The steel reinforcement support 5 includes the main steel reinforcement 503 of the corbel column 3 inserted inside the corbel column 3. Multiple hook steel reinforcements 504 are provided between the main steel reinforcements 503 of the corbel column. The main steel reinforcements 503 of the corbel column and the hook steel reinforcements 504 are fixed by binding. The hook steel reinforcements 504 are made by bending steel bars and can be welded to the main horizontal steel reinforcement 502 to increase the overall stability.

[0027] The steel reinforcement support 5 also includes the main steel bars 501 inserted into the deep-buried column 2. The main horizontal steel bars 502 are evenly distributed at equal intervals between the main steel bars 501. The main horizontal steel bars 502, which match the height of the corbel column 3, are welded to the hook steel bars 504. The main steel bars 501 and the main horizontal steel bars 502 are fixed by binding.

[0028] By adopting the above technical solution, the reinforcing bars in the steel reinforcement support 5 are tied together. After tying, they are erected and poured together to form the corbel column 3 and the deeply embedded column 2. After the corbel concrete is poured, it should be cured immediately after the surface solidifies. During the curing period, the concrete surface should be kept moist, avoiding direct sunlight and wind drying. In special environments such as high temperature, low temperature, dryness, and humidity, corresponding curing measures should be taken. During the curing period, the moisture level and curing effect of the concrete surface should be checked regularly, and problems should be identified and addressed in a timely manner to ensure the quality and durability of the corbel column 3. The concrete cube compressive strength of the corbel column 3 must reach 100% before the supporting scaffolding can be removed. By replacing the original enlarged column and foundation connecting beam with the corbel column 3, the amount of concrete used is greatly reduced, thereby reducing the project cost. Furthermore, since the corbel column 3 is supported by hooked steel bars 504, the connection stability between the corbel column 3 and the deeply embedded column 2 can be increased, ensuring that the corbel column 3 can be used normally.

[0029] Specifically, such as Figure 3 As shown, the connecting reinforcement component 4 includes supports 401 installed on the sides of the corbel column 3 and the buried column 2 respectively. The supports 401 have an L-shaped structure. Expansion bolts 404 are installed at the connection between the supports 401 and the corbel column 3 and the buried column 2, and the expansion bolts 404 are inserted into the interior of the corbel column 3 and the buried column 2. A connecting bolt 402 is installed on the top of the supports 401. A reinforcing steel wire rope 403 is passed through the top of the connecting bolt 402 through a pin hole. The bottom plane of the corbel surface of the corbel column 3 is on the same horizontal plane as the bottom plane of the existing foundation connecting beam.

[0030] By adopting the above technical solution, after the corbel column 3 is made, supports 401 are installed on the sides of the corbel column 3 and the buried column 2 respectively. The supports 401 are fixed by multiple expansion bolts 404, and connecting bolts 402 are installed on the supports 401 of the corbel column 3 and the buried column 2. The connecting bolts 402 pass through the mounting holes opened at the top of the supports 401 and are locked at the bottom by nuts. The reinforcing steel wire rope 403 passes through the pin holes at the top of the connecting bolts 402 and is fixed by fasteners. The reinforcing steel wire rope 403 can pull the corbel column 3 from above, making the connection strength between the corbel column 3 and the buried column 2 higher. The upper end face of the corbel column 3 is at the same height as the foundation connecting beam, which is -0.060.

[0031] Working principle: The reinforcing bars in the steel reinforcement support 5 are tied together. After tying, the formwork is erected and the concrete is poured together to form the corbel column 3 and the deeply embedded column 2. After the corbel concrete is poured, it should be cured immediately after the surface solidifies. During the curing period, the concrete surface should be kept moist, and direct sunlight and wind drying should be avoided. In special environments such as high temperature, low temperature, dryness, and humidity, corresponding maintenance measures should be taken. During the maintenance period, the moisture level and maintenance effect of the concrete surface should be checked regularly, and problems should be identified and addressed in a timely manner to ensure the quality and durability of the corbel column 3. The concrete cube compressive strength of the corbel column 3 must reach 100% before the supporting scaffolding can be removed. After the corbel column 3 is made, supports 401 are installed on the sides of the corbel column 3 and the deep-buried column 2 respectively. The supports 401 are fixed by multiple expansion bolts 404, and connecting bolts 402 are installed on the supports 401 of the corbel column 3 and the deep-buried column 2. The connecting bolts 402 pass through the installation holes opened at the top of the supports 401 and are locked at the bottom by nuts. The reinforcing steel wire rope 403 passes through the pin holes at the top of the connecting bolts 402 and is fixed by fasteners.

[0032] 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 the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
