Description

Technical Field

[0001] This utility model relates to the field of prefabricated steel structures, and in particular to a prefabricated steel structure ground anchor bolt. Background Technology

[0002] Prefabricated steel structures are a new type of building that involves factory-produced steel structural components that are assembled and connected on-site to form a complete steel structure building. Prefabricated steel structure buildings have a wide range of applications, including industrial plants, residential buildings, and commercial buildings. In industrial plants, prefabricated steel structure buildings are widely used in factories and warehouses due to their advantages such as high strength, fast construction speed, and low cost. In the residential sector, as people's demands for quality of life increase, the characteristics of prefabricated steel structure buildings are better reflected. Meanwhile, in the commercial sector, prefabricated steel structure buildings can be used in large-scale commercial projects such as department stores, hotels, and exhibition halls.

[0003] Ground anchor bolts, also known as anchor bolts or ground bolts, are fasteners that connect the superstructure to the foundation. In the installation of prefabricated steel structures, ground anchor bolts are typically pre-installed to ensure the stability of the steel structure before connecting it to the bolt. In the authorized Chinese utility model patent "Announcement No.: CN206478395U, Title: Ground Anchor Bolt," multiple hooks are evenly distributed on the circumference of the bolt body and embedded in the foundation, increasing friction and strengthening the bolt's fixing strength. However, in cases where the hooks need to be subsequently inserted into the soil, the hooks can cause soil loosening upon insertion, affecting the overall stability of the ground anchor bolt and thus the stability of the prefabricated steel structure installation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defect of low stability of ground anchor bolts during installation in the prior art, which affects the stability of prefabricated steel structures, and to provide ground anchor bolts for prefabricated steel structures.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model provides a prefabricated steel structure ground anchor bolt, including a main column.

[0007] A threaded column, wherein the upper end of the main column is connected to a threaded column;

[0008] The mounting housing is connected to the lower end of the main column. Multiple reinforcing strips are rotatably connected to the inner side of the mounting housing. The multiple reinforcing strips are connected to a rotating component. The rotating component is connected to a pushing component. The pushing component is slidably connected to the surface of the main column. The pushing component is used to adjust the rotating component so that the rotating component rotates the reinforcing strips and moves the reinforcing strips out of the main column.

[0009] A fixed base is attached to the lower end of the mounting housing.

[0010] In this technical solution, the pushing component can drive the rotating component to rotate. When the rotating component rotates, the reinforcing strip can be rotated out of the mounting shell, allowing multiple mounting shells to penetrate deep into the ground. This increases the contact area between the ground anchor bolt and the underground material, thereby increasing friction and making the ground anchor bolt more stable during use, thus increasing the stability of the prefabricated steel structure.

[0011] Meanwhile, the ground anchor bolts of this application can be adapted to situations where installation is required later or where installation is required before grouting, and have a wide range of applications. In all of the above situations, it is convenient to install the ground anchor thread without affecting its stability.

[0012] Preferably, the side of the reinforcing strip furthest from the inner cavity of the mounting housing has a triangular structure.

[0013] In this technical solution, the triangular structure facilitates soil cutting and the extension of the reinforcing strip.

[0014] Preferably, the rotating assembly includes a movable rack plate, which is slidably configured for mounting the inner cavity of the housing. Multiple rotating gears are meshed on both sides of the movable rack plate, and the sides of the rotating gears are rotatably connected to the inner wall of the housing.

[0015] The rotating gear has a reinforcing strip attached to its surface.

[0016] In this technical solution, the rotating component facilitates the rotation of the reinforcing strip.

[0017] Preferably, the inner wall of the mounting housing is connected to a positioning strip, the movable rack plate has a moving opening, and the positioning strip is slidably connected to the movable rack plate through the moving opening.

[0018] In this technical solution, the movement trajectory of the moving rack plate can be limited by the positioning bar.

[0019] Preferably, a limiting plate is connected to the bottom end of the movable rack plate, and the limiting plate slides within the mounting housing.

[0020] In this technical solution, the use of a limiting plate in conjunction with a positioning strip can further prevent the moving rack plate from deviating from its trajectory during movement.

[0021] Preferably, the mounting housing has preset openings on both sides, and the walls of the preset openings are connected to two symmetrically distributed elastic sealing strips.

[0022] In this technical solution, the use of elastic sealing tape can reduce the probability of soil entering the installation housing, facilitating the operation of various structures of the rotating component.

[0023] Preferably, the pushing component includes a connecting column, the bottom end of which is connected to the top end of the movable rack plate, and the surface of the connecting column is slidably connected through the top surface of the mounting housing and the bottom surface of the main column;

[0024] A push plate is connected to the top of the connecting column. The push plate is located in the inner cavity of the main column. Multiple push columns arranged in a ring array are connected to the top of the push plate. The surface of the push column is slidably connected to the main column.

[0025] The top of the push column is connected to the bottom of the connecting plate, and the connecting plate is slidably sleeved on the surface of the threaded column.

[0026] In this technical solution, the pushing component can drive the rotating component, providing driving force for the rotation of the rotating component.

[0027] Preferably, the fixed base includes a support column, the top of which is connected to the bottom of the mounting housing, and the bottom of which is connected to the top of the stabilizing base plate.

[0028] The side of the support column is connected to a plurality of reinforcing ribs arranged in a ring array, and the bottom of the reinforcing ribs is connected to the top of the stabilizing base plate.

[0029] In this technical solution, the use of a fixed base can increase the stability of the anchor bolt installation.

[0030] Preferably, the threaded column surface is threaded with a fixing nut.

[0031] In this technical solution, the use of a fixing nut facilitates the installation and connection of the threaded column with the prefabricated steel structure.

[0032] Preferably, a plurality of connecting stiffeners are connected between the bottom of the main column and the supporting column.

[0033] In this technical solution, the stability of the installed shell structure can be increased by using connecting stiffeners.

[0034] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0035] The positive and progressive effects of this utility model are as follows:

[0036] This utility model utilizes a pushing component to drive a rotating component to rotate. When the rotating component rotates, it can rotate the reinforcing strip out of the mounting shell, allowing multiple mounting shells to penetrate deep into the ground. This increases the contact area between the ground anchor bolt and the underground material, thereby increasing friction and making the ground anchor bolt more stable during use, thus increasing the stability of the prefabricated steel structure.

[0037] Meanwhile, the ground anchor bolts of this application can be adapted to situations where installation is required later or where installation is required before grouting, and have a wide range of applications. In all of the above situations, it is convenient to install the ground anchor thread without affecting its stability. Attached Figure Description

[0055] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0056] Figures 1 to 7 The diagram shown is a structural schematic of an embodiment of the prefabricated steel structure ground anchor bolt of this utility model. The prefabricated steel structure ground anchor bolt includes a main column 1.

[0057] Threaded post 2, the upper end of the main post 1 is connected to the threaded post 2;

[0058] The mounting housing 3 is connected to the lower end of the main column 1. Multiple reinforcing strips 4 are rotatably connected to the inner side of the mounting housing 3. The multiple reinforcing strips 4 are connected to the rotating component 5. The rotating component 5 is connected to the pushing component 6. The pushing component 6 is slidably connected to the surface of the main column 1. The pushing component 6 is used to adjust the rotating component 5 so that the rotating component 5 rotates the reinforcing strips 4 and moves the reinforcing strips 4 out of the main column 1.

[0059] A fixed base 7 is connected to the lower end of the mounting housing 3.

[0060] In this technical solution, the pushing component 6 can drive the rotating component 5 to rotate. When the rotating component 5 rotates, the reinforcing strip 4 can be rotated out of the mounting shell 3, so that multiple mounting shells 3 can penetrate deep into the ground, thereby increasing the contact area between the ground anchor bolt and the underground material, thereby increasing friction, making the ground anchor bolt more stable during use, and thus increasing the stability of the prefabricated steel structure.

[0061] Meanwhile, the ground anchor bolts of this application can be adapted to situations where installation is required later or where installation is required before grouting, and have a wide range of applications. In all of the above situations, it is convenient to install the ground anchor thread without affecting its stability.

[0062] The side of the reinforcing strip 4 furthest from the inner cavity of the mounting housing 3 has a triangular structure.

[0063] In this technical solution, the triangular structure facilitates soil cutting and the extension of the reinforcing strip 4.

[0064] The rotating assembly 5 includes a movable rack plate 51, which is slidably configured for mounting the inner cavity of the housing 3. Multiple rotating gears 52 are meshed on both sides of the movable rack plate 51, and the sides of the rotating gears 52 are rotatably connected to the inner wall of the housing 3.

[0065] The rotating gear 52 has a reinforcing strip 4 attached to its surface.

[0066] In this technical solution, the rotating component 5 facilitates the rotation of the reinforcing strip 4.

[0067] The inner wall of the mounting housing 3 is connected to a positioning strip 53, and the movable rack plate 51 has a moving opening. The positioning strip 53 is slidably connected to the movable rack plate 51 through the moving opening.

[0068] In this technical solution, the positioning bar 53 can be used to limit the movement trajectory of the moving rack plate 51.

[0069] The bottom end of the movable rack plate 51 is connected to a limiting plate 54, which slides within the mounting housing 3.

[0070] In this technical solution, the use of the limiting plate 54 in conjunction with the positioning strip 53 can further prevent the moving rack plate 51 from deviating from its trajectory during movement.

[0071] In use, the push component 6 can drive the moving rack plate 51 to move, which in turn drives the rotating gear 52 to rotate. At this time, the reinforcing strip 4 can rotate and extend out of the mounting shell 3. The multiple mounting shells 3 increase the contact area with the underground material, increase the stability of the ground anchor bolts, and thus increase the stability of the prefabricated steel structure.

[0072] The mounting housing 3 has preset openings on both sides, and the walls of the preset openings are connected to two symmetrically distributed elastic sealing strips 55.

[0073] In this technical solution, the elastic sealing strip 55 can reduce the probability of soil entering the installation housing 3, which facilitates the operation of each structure of the rotating component 5.

[0074] The pushing component 6 includes a connecting post 61, the bottom end of which is connected to the top end of the movable rack plate 51, and the surface of the connecting post 61 is slidably connected through the top surface of the mounting housing 3 and the bottom surface of the main column 1.

[0075] The top of the connecting column 61 is connected to a push plate 62, which is disposed in the inner cavity of the main column 1. The top of the push plate 62 is connected to a plurality of push columns 63 arranged in a ring array, and the surface of the push column 63 is slidably connected to the main column 1.

[0076] The top of the push column 63 is connected to the bottom of the connecting plate 64, and the connecting plate 64 is slidably sleeved on the surface of the threaded column 2.

[0077] In this technical solution, the pushing component 6 can drive the rotating component 5, providing driving force for the rotation of the rotating component 5.

[0078] In use, the connecting plate 64 drives the push column 63 to move downward, which in turn drives the push plate 62 to move in the same direction, and then drives the connecting column 61 to move in the same direction. At this time, the connecting column 61 can drive the moving rack plate 51 to move in the same direction.

[0079] The fixed base 7 includes a support column 71, the top of which is connected to the bottom of the mounting housing 3, and the bottom of which is connected to the top of the stable base plate 72.

[0080] The side of the support column 71 is connected to a plurality of reinforcing ribs 73 arranged in a ring array, and the bottom of the reinforcing ribs 73 is connected to the top of the stabilizing base plate 72.

[0081] In this technical solution, the fixed base 7 can be used to increase the stability of the anchor bolt installation.

[0082] When in use, underground materials or cast-in-place materials enter the gap between adjacent reinforcing ribs 73, thereby increasing the stability of the supporting column 71 and the stable base plate 72, and further increasing the stability of the ground anchor bolts.

[0083] The threaded post 2 is threaded with a fixing nut 8.

[0084] In this technical solution, the use of fixing nut 8 facilitates the installation and connection of threaded column 2 with prefabricated steel structure.

[0085] Multiple connecting stiffeners 9 are connected between the bottom of the main column 1 and the supporting column 71.

[0086] In this technical solution, the connecting stiffener 9 can be used to increase the stability of the housing 3 structure.

[0087] For situations where it is necessary to pour and install ground anchor bolts, the connecting plate 64 can be made to contact the main column 1 first, so that the reinforcing strip 4 can be extended, and then the material can be poured.

[0088] In cases where ground anchor bolts need to be installed directly, the ground anchor bolts need to be installed underground first, and then the connecting plate 64 and other structures need to be moved to allow the reinforcing strip 4 to extend.

[0089] In use, the prefabricated steel structure is installed on the surface of the threaded column 2, and then the fixing nut 8 is installed on the surface of the threaded column 2. At this time, under the weight of the prefabricated steel structure and the tightening action of the fixing nut 8, the connecting plate 64 can be pressed against the main column 1, which can drive the push column 63 and other structures to move down, and then drive the rotating component 5 to rotate, extending the reinforcing strip 4.

[0090] Example 2

[0091] As an embodiment of this application, the top of the main column 1 and the connecting plate 64 are provided with multiple threaded holes and slots. The main column 1 and the connecting plate 64 are connected by fixing bolts through the threaded holes and slots.

[0092] The main column 1 and the connecting plate 64 are connected by fixing bolts, which causes the structure such as the pushing column 63 to move down, thereby driving the rotating component 5 to rotate. At this time, the reinforcing strip 4 can be extended to fix the ground anchor bolts without installing the prefabricated steel structure.

[0093] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
