Description

Technical Field

[0001] The utility model belongs to the technical field of foundation reinforcement, and in particular relates to a construction engineering foundation reinforcement device. Background Art

[0002] Building foundations are divided into natural foundations and artificial foundations. Foundations that can directly bear the load of buildings without treatment are called natural foundations. Conversely, foundations that need to be treated by foundation treatment technology are called artificial foundations. Broadly speaking, artificial foundations can be divided into three types of foundations. The first is homogeneous foundations and multi-layer foundations. Through improvement or replacement, the physical and mechanical properties of the foundation soil are improved, the shear strength of the foundation soil is increased, the compression modulus of the soil is enhanced, or the permeability of the soil is reduced. The second is a composite foundation. By setting vertical or horizontal reinforcements in the foundation, the reinforcements and the original foundation form a composite foundation to increase the bearing capacity of the foundation soil and reduce foundation settlement. The third is pile foundations. Piles are set in the foundation to transfer the load to the deep soil through the piles.

[0003] Foundation reinforcement piles are commonly used reinforcement devices in engineering projects. They play a reinforcing role in buildings or strata, and will withstand a certain load force to improve the stability of buildings or ground projects. Most of the existing foundation reinforcement piles are simple cast concrete columns with a small contact area with the soil layer and poor pull-out resistance. In addition, the concrete reinforcement piles themselves have a simple structure and low stability.

[0004] Therefore, a construction engineering foundation reinforcement device is needed to solve the problems in the prior art that the foundation reinforcement pile has a small contact area with the soil layer, has a poor pull-out resistance, and the concrete reinforcement pile itself has a simple structure and low stability.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a foundation reinforcement device for a construction project, comprising a support column, a pointed pile is fixedly connected to the outer surface of the bottom end of the support column, a pressure plate is fixedly connected to the outer surface of the top end of the support column, a plurality of barbs distributed at equal distances are fixedly connected to the outer surfaces of both sides of the support column, a fixing plate is fastened and sleeved on the outer surface of the bottom of the support column, a plurality of fixing columns distributed in an annular manner are fixedly connected to the bottom surface of the fixing plate, and a plurality of groups of clamping rods distributed in an annular manner are fixedly connected to the outer surface of the fixing column.

[0007] It should be noted in the solution that a cavity is provided at the center of the bottom end of the support column, a threaded hole is opened at the center of the support column, the cavity is connected to the threaded hole, and the threaded hole passes through the top end of the support column.

[0008] It is further worth explaining that a threaded rod is threadedly connected to the threaded hole, a movable plate is fixedly connected to the outer surface of the bottom end of the threaded rod, the movable plate is slidably connected to the cavity, and sliding rods are fixedly connected to both sides of the top of the cavity. The two sliding rods are distributed in parallel, and the sliding rods slide through the movable plate.

[0009] It should be further explained that the two ends of the bottom surface of the movable plate are rotatably connected to a connecting rod through a lug and a pin shaft, and the other end of the connecting rod is rotatably connected to a side insertion rod through a lug and a pin shaft. Through holes are provided at the front and rear ends of the outer surface of the bottom of the support column, and the outer surface of the side insertion rod is slidably connected to the through hole.

[0010] As a preferred embodiment, a conical head is fixedly connected to the outer surface of the bottom end of the fixing column, and a pointed end is fixedly connected to the outer surface of the side insertion rod away from the connecting rod.

[0011] As a preferred embodiment, the top of the threaded rod passes through the pressure plate, the threaded rod is rotatably connected to the pressure plate, and the outer surfaces on both sides of the top of the threaded rod are fixedly connected with rotating handles.

[0012] Compared with the prior art, the construction engineering foundation reinforcement device provided by the utility model has at least the following beneficial effects:

[0013] (1) By setting a pointed pile at the bottom of the support column, it is convenient to insert the support column into the soil. When the support column goes deep into the soil, the barbs on both sides of the support column are inserted into the soil, and the fixing plate drives the fixed column to go deep into the soil. By fixing a number of clamping rods on the side of the fixed column, the contact area between the support column and the soil layer is increased. After pouring concrete into the groove to form a reinforcement pile, the problem of small contact area of ​​the foundation reinforcement pile with the soil layer and poor pull-out effect is effectively avoided.

[0014] (2) The threaded rod is adjusted to allow the movable plate to slide downward in the cavity. The connecting rod drives the side insertion rods to slide outward in the through holes when the movable plate slides downward. The two side insertion rods move outward and are inserted into the concrete layer, thereby increasing the contact area between the device and the concrete layer, thereby reinforcing the device. When the concrete layer is completely dry, the device completely overlaps with the concrete layer, thereby improving the stability of the reinforcement pile itself and effectively avoiding the problem of the simple structure and low stability of the concrete reinforcement pile itself.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] See also Figure 1-3 The utility model provides a foundation reinforcement device for a construction project, including a support column 1, a pointed pile 2 is fixedly connected to the outer surface of the bottom end of the support column 1, a pressure plate 4 is fixedly connected to the outer surface of the top end of the support column 1, a plurality of barbs 3 distributed at equal distances are fixedly connected to the outer surfaces of both sides of the support column 1, a fixing plate 5 is fastened and sleeved on the outer surface of the bottom of the support column 1, a plurality of fixing columns 6 distributed in an annular manner are fixedly connected to the bottom surface of the fixing plate 5, and a plurality of groups of clamping rods 7 distributed in an annular manner are fixedly connected to the outer surface of the fixing column 6.

[0021] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that a cavity 9 is provided at the center of the bottom end of the support column 1 , a threaded hole 10 is opened at the center of the support column 1 , the cavity 9 is connected to the threaded hole 10 , and the threaded hole 10 passes through the top end of the support column 1 .

[0022] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that a threaded rod 11 is connected to the inner thread of the threaded hole 10, a movable plate 12 is fixedly connected to the outer surface of the bottom end of the threaded rod 11, the movable plate 12 is slidably connected to the cavity 9, and sliding rods 13 are fixedly connected to both sides of the top of the cavity 9. The two sliding rods 13 are distributed in parallel, and the sliding rods 13 slide through the movable plate 12.

[0023] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the two ends of the bottom surface of the movable plate 12 are rotatably connected to the connecting rod 14 through the lugs and the pin shaft, and the other end of the connecting rod 14 is rotatably connected to the side insertion rod 15 through the lugs and the pin shaft, and the front and rear ends of the outer surface of the bottom of the support column 1 are provided with through holes 16, and the outer surface of the side insertion rod 15 is slidably connected to the through holes 16.

[0024] This solution has the following working process: when reinforcing the foundation of a construction project, first put the support column 1, the pressure plate 4 and the fixed plate 5 into the opened groove, hit the pressure plate 4, and use the pointed pile 2 set at the bottom of the support column 1 to facilitate the insertion of the support column 1 into the foundation where the reinforcement pile needs to be buried. At the same time, multiple barbs 3 on the left and right sides of the support column 1 are inserted into the soil. While penetrating, the fixed plate 5 drives the fixed column 6 to penetrate into the soil. A number of clamping rods 7 are fixedly connected to the side of the fixed column 6, which increases the contact area between the support column 1 and the soil layer and enhances the pull-out resistance of the reinforced pile formed by pouring concrete into the groove.

[0025] Concrete is poured into the opened groove, and the threaded rod 11 is rotated to move downward in the threaded hole 10, so that the movable plate 12 slides downward in the cavity 9. Under the action of the connecting rod 14, the side insertion rod 15 slides out of the through hole 16. At this time, the two side insertion rods 15 are inserted into the concrete to increase the contact area between the device and the concrete layer, thereby reinforcing the device. When the concrete layer is dry, the device completely overlaps with the concrete layer, and has higher stability than traditional concrete columns.

[0026] According to the above working process, it can be known that: by setting a pointed pile 2 at the bottom of the support column 1, it is convenient to insert the support column 1 into the soil. When the support column 1 goes deep into the soil, the barbs 3 on both sides of the support column 1 are inserted into the soil, and the fixing plate 5 drives the fixing column 6 to go deep into the soil. By fixing and connecting a number of clamping rods 7 on the side of the fixing column 6, the contact area between the support column 1 and the soil layer is increased. After pouring concrete into the groove to form a reinforcement pile, the problem of small contact area of ​​the foundation reinforcement pile with the soil layer and poor pull-out resistance is effectively avoided.

[0027] By adjusting the threaded rod 11, the movable plate 12 slides downward in the cavity 9. Through the action of the connecting rod 14, the side insertion rods 15 are driven to slide outward in the through holes 16 when the movable plate 12 slides downward. The two side insertion rods 15 move outward and are inserted into the concrete layer, thereby increasing the contact area between the device and the concrete layer, thereby reinforcing the device. When the concrete layer is completely dry, the device completely overlaps with the concrete layer, thereby improving the stability of the reinforcement pile itself and effectively avoiding the problem of the simple structure and low stability of the concrete reinforcement pile itself.

[0028] Further as Figure 1 and Figure 3 As shown, it is worth specifically explaining that a conical head 8 is fixedly connected to the outer surface of the bottom end of the fixing column 6, so as to facilitate better insertion of the fixing column 6 into the soil, and a tip 17 is fixedly connected to the outer surface of the side insertion rod 15 away from the connecting rod 14, so as to facilitate better insertion of the side insertion rod 15 into the concrete.

[0029] Further as Figure 1As shown, it is worth explaining in detail that the top of the threaded rod 11 passes through the pressure plate 4, the threaded rod 11 is rotatably connected to the pressure plate 4, and the outer surfaces on both sides of the top of the threaded rod 11 are fixedly connected with a turning handle 18 to facilitate workers to rotate the threaded rod 11.

[0030] In summary: when reinforcing the foundation of a construction project, first place the support column 1, the pressure plate 4 and the fixed plate 5 into the opened groove, hit the pressure plate 4, and through the pointed pile 2 set at the bottom of the support column 1, it is convenient to insert the support column 1 into the foundation where the reinforcement pile needs to be buried. At the same time, the multiple barbs 3 on the left and right sides of the support column 1 are inserted into the soil. While penetrating, the fixed plate 5 drives the fixed column 6 to penetrate into the soil. The outer surface of the bottom end of the fixed column 6 is fixedly connected with a conical head 8, which is convenient for better inserting the fixed column 6 into the soil. A number of clamping rods 7 are fixedly connected to the side of the fixed column 6, which increases the contact area between the support column 1 and the soil layer, enhances the pull-out resistance of the reinforced pile formed by pouring concrete into the groove, and effectively avoids the problem of small contact area of ​​the foundation reinforcement pile with the soil layer and poor pull-out resistance.

[0031] Pour concrete into the opened groove, rotate the threaded rod 11 by the turning handle 18, so that the threaded rod 11 moves downward in the threaded hole 10, and then the movable plate 12 slides downward in the cavity 9, and the side insertion rod 15 slides outward from the through hole 16 under the action of the connecting rod 14. The outer surface of the side insertion rod 15 away from the connecting rod 14 is fixedly connected with a tip 17, which is convenient for better inserting the side insertion rod 15 into the concrete. At this time, two side insertion rods 15 are inserted into the concrete to increase the contact area between the device and the concrete layer, thereby reinforcing the device. When the concrete layer is dry, the device completely overlaps with the concrete layer, and has higher stability than traditional concrete columns, effectively avoiding the problems of simple structure and low stability of the concrete reinforcement pile itself.
