Description

Technical Field

[0001] This utility model relates to a pile body for a building, and more particularly to a light steel structure foundation pile. Background Technology

[0002] See Figure 1 , 2 The existing foundation device 1 includes a settlement suppression plate 11 with multiple holes 110 suitable for placement on soil layer F, a base plate 12 with multiple downward through holes 120 placed on the settlement suppression plate 11, multiple support rods 13 extending upward from the base plate 12, a top plate 14 with multiple upward through holes 140 mounted on the support rods 13 and longitudinally spaced from the base plate 12, and a multiple steel pipes 15 for insertion into the soil layer F by passing through the upward through holes 140 and corresponding downward through holes 120. Guided by the upward through holes 140 and downward through holes 120, the steel pipes 15 are inserted obliquely into the soil layer F at a specific distance through the holes 110, thereby positioning the foundation device 1 on the soil layer F via the steel pipes 15. Subsequently, with the distribution and installation of multiple foundation devices 1, construction can continue on the top plate 14 of each foundation device 1 to build the desired building structure.

[0003] When installing the foundation device 1, each steel pipe 15 must be inserted into the soil layer F to a certain depth, necessitating the use of a power tool to impact it from the top with strong external force. During this process, it is crucial to ensure precise alignment between the components; otherwise, it will be difficult to withstand the powerful impact. However, since the settlement suppression plate 11 is not pre-fixed to the soil layer F, and considering that the holes 110 of the settlement suppression plate 11 and the lower perforations 120 of the base plate 12 must be pre-aligned, the base plate 12 and the settlement suppression plate 11 will not be pre-fixed to each other. Therefore, before the steel pipes 15 are inserted, the settlement suppression plate 11 and the soil layer F, as well as the settlement suppression plate 11 and the base plate 12, are relatively movable. Thus, using a power tool to impact and insert the steel pipes 15 will obviously result in instability and inaccuracy deviations. Considering various interference factors, this will significantly increase the difficulty of construction and affect construction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight steel structure foundation pile that is easy to construct and can optimize the overall structural strength.

[0005] This utility model relates to a light steel structure foundation pile, which is suitable for installation in soil layers and includes a main unit suitable for installation in the soil layer and a pipe fitting unit installed on the main unit.

[0006] The main unit includes a base plate with multiple lower through holes, a support column fixed to the base plate and extending upward, a base plate extending laterally from the support column and adjacent to the base plate and having multiple upper through holes, multiple outer guide tubes extending upward from the lower through holes to the upper through holes and each defining a guide channel, and at least two positioning columns located on different sides relative to the support column and extending downward from the base plate and suitable for insertion into the soil layer.

[0007] The pipe fitting unit includes multiple outer steel pipes that are inserted into the soil layer through guide channels that pass through the outer conduit.

[0008] The lightweight steel structure foundation pile of this utility model has a base plate of the main unit with multiple lower through holes, a base plate with multiple upper through holes, and the main unit also includes multiple inner guides that extend downward from the upper through holes to the lower through holes and each defines an insertion channel facing the bottom of the support. The pipe unit also includes multiple inner steel pipes that pass through the insertion channels of the inner guides and are inserted into the soil layer.

[0009] The lightweight steel structure foundation pile of this utility model has a rectangular base plate of the main unit with four lower through holes located at the four corners. The base plate has four upper through holes with longitudinal projection ranges that are laterally offset from the lower through holes, so that when each outer steel pipe is inserted into an individual guide channel, it extends downwards at an angle away from the support.

[0010] The lightweight steel structure foundation pile of this utility model has an angle of 30 to 60 degrees between each outer guide tube of the main unit and the horizontal plane.

[0011] The lightweight steel structure foundation pile of this utility model has four lower through holes on the base plate of the main unit, which are respectively offset from the lower through hole, and four upper through holes whose longitudinal projection range is respectively offset from the lower through holes, so that when each inner steel pipe is inserted into an individual through channel, it extends downward in the direction below the support.

[0012] The lightweight steel structure foundation pile of this utility model has an angle of 60 to 80 degrees between each inner guide tube of the main unit and the horizontal plane.

[0013] The lightweight steel structure foundation pile of this utility model has a support column selected from H-beams, C-beams, round tubes, or square tubes.

[0014] The present invention relates to a lightweight steel structure foundation pile, wherein each inner steel pipe of the pipe unit has an inner oblique insertion part with one end shaped as an oblique opening, suitable for insertion into the soil layer.

[0015] The present invention relates to a lightweight steel structure foundation pile, wherein each outer steel pipe of the pipe unit has an oblique end suitable for insertion into the soil layer.

[0016] The beneficial effects of this utility model are as follows: the positioning column can pre-position the main body unit in the soil layer at the position below the column, so that the main body unit is stably set on the soil layer. When the main body unit does not move relative to the base unit or the soil layer, the stability can be optimized when the outer steel pipe is installed. Furthermore, the guide channel can eliminate the process of aligning the holes during construction, effectively improving the accuracy and stability of the installation, so as to simplify the construction and ensure the overall structural strength.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] See Figure 3 , 4 An embodiment of the lightweight steel structure foundation pile of this utility model is applicable to installation in a soil layer 9. This embodiment includes a main body unit 3 suitable for installation on the soil layer 9, and a pipe fitting unit 4 installed on the main body unit 3.

[0027] The main body unit 3 includes a base plate 31 having multiple lower through holes 311 and multiple lower through holes 312, a support column 32 fixed to the base plate 31 and extending upward, a base plate 33 extending laterally from the support column 32 and adjacent to the base plate 31 and having multiple upper through holes 331 and multiple upper through holes 332 located outside the upper through holes 331, multiple inner guide tubes 34 extending downward from the upper through holes 331 to the lower through holes 311 and each defining an insertion channel 340 facing downward from the support column 32, multiple outer guide tubes 35 extending upward from the lower through holes 312 to the upper through holes 332 and each defining a guide channel 350, and at least two positioning rods 36 located on different sides relative to the support column 32 and extending downward from the base plate 31 and suitable for insertion into the soil layer 9. The support column 32 primarily serves as the foundation for subsequent construction. Depending on the needs of different buildings, it is preferably selected from an H-beam, a C-beam, a round pipe, or a square pipe. In this embodiment, an H-beam is used as an example, but it is not limited to the aforementioned types. The positioning column 36 is pre-fixed to the base plate 31 or integrally formed during the manufacturing stage. During use, the positioning column 36 is inserted into the soil layer 9 to initially position the main unit 3.

[0028] See Figure 5 In this embodiment, the distribution of the lower through hole 311 and the upper through hole 331 is designed so that the through channel 340 surrounds the support column 32 and faces downward toward the support column 32; while the distribution of the lower through hole 312 and the upper through hole 332 is designed so that the guide channel 350 surrounds the support column 32 and slopes outward along the surrounding direction. Specifically, in terms of projection perpendicular to the ground, the lower through hole 311 is closer to the support column 32 than the upper through hole 331, while the lower through hole 312 is formed at approximately the four corners of the base plate 31, thereby the position of the upper through hole 332 corresponding to the lower through hole 312 is offset laterally. However, in actual implementation, the distribution and correspondence of the lower through hole 311 and the upper through hole 331, or the lower through hole 312 and the upper through hole 332, can be adjusted to meet subsequent construction needs, thereby changing the extension and distribution of the insertion channel 340 and the guide channel 350. This embodiment is not the only limitation. Figure 6 As shown, each inner catheter 34 has an angle of 60 to 80 degrees with the horizontal plane, preferably 60 degrees, while each outer catheter 35 has an angle of 30 to 60 degrees with the horizontal plane, preferably 45 degrees.

[0029] See Figure 6 and Figure 7The positioning rod 36 can be selected in different implementations, such as... Figure 6 The two positioning posts 36 are respectively arranged diagonally on the base plate 31; or they can also be arranged as follows: Figure 7 The four positioning posts 36 are positioned on the front, back, left, and right sides of the support column 32, respectively. As long as the positioning posts 36 are positioned at least on opposite sides of the support column 32, the stability of the initial positioning of the main unit 3 on the soil layer 9 can be ensured.

[0030] See also Figure 8 and cooperate Figure 4 and Figure 5 The pipe fitting unit 4 includes multiple inner steel pipes 41 that pass through the insertion channels 340 of the inner conduit 34 and are inserted into the soil layer 9, and multiple outer steel pipes 42 that pass through the guide channels 350 of the outer conduit 35 and are inserted into the soil layer 9. Each inner steel pipe 41 has an inner oblique insertion portion 419 with one end shaped like an oblique opening for insertion into the soil layer 9, and each outer steel pipe 42 has an outer oblique insertion portion 429 with one end shaped like an oblique opening for insertion into the soil layer 9. This design helps to increase the unit area pressure during insertion by reducing the contact area with the soil layer 9, making it easier for each inner steel pipe 41 and each outer steel pipe 42 to be inserted into the soil layer 9.

[0031] When setting up the main body unit 3, it is only necessary to first... Figure 4 As shown, the positioning column 36 is inserted into the soil layer 9, thereby initially positioning the main body unit 3 in a specific position. Then, the inner steel pipe 41 is passed through the insertion channel 340 of the inner guide 34, so that the inner steel pipe 41 extends to the position below the support column 32, thereby creating an effect similar to holding the soil layer 9, so as to reliably position the main body unit 3.

[0032] Since the main body unit 3 is already positioned and will not move, during the process of inserting the outer steel pipe 42, not only can the outer steel pipe 42 be directly inserted into the guide channel 350, eliminating the need for alignment holes, but also the stability of the main body unit 3 can be ensured when the outer steel pipe 42 is subjected to an impact force by a power tool (not shown in the figure). This allows the outer steel pipe 42 to be accurately inserted downwards and at an angle away from the support column 32 into the soil layer 9 at the expected position.

[0033] The outer steel pipe 42 is preferably inserted into the soil layer 9 to a depth of 1 to 3 meters. After being inserted at a 45-degree angle along the guide channel 350, and given that the soil layer 9 is sandy soil and the "standard injection N value" for judging its looseness is 4, the 1.5-meter-long outer steel pipe 42, together with the inner steel pipe 41, creates an effect similar to holding the soil layer 9, which can generate a pull-out force of 40.18 (KN). This provides the conditions for constructing a light steel structure building using the support column 32 in this embodiment. It can then be used to construct steel foundations for structures such as solar panels, sports fields, parking lots, farm sheds, or fish sheds. Given its ease of construction, it is also more versatile and applicable to flat land, hillsides, backfilled land, and other similar sites.

[0034] It should be further noted that, since the main unit 3 in this embodiment is fixed only by the positioning column 36, the inner steel pipe 41, and the outer steel pipe 42, and does not use a positioning structure similar to a cement pile, it will not remain in the soil and affect the subsequent use of other land. Therefore, if the light steel structure constructed in this embodiment is no longer used, this embodiment can be easily dismantled by simply removing the inner steel pipe 41 and the outer steel pipe 42, and the land originally used for construction can be quickly repurposed.
