Description

Technical Field

[0001] This application relates to the technical field of fencing, and in particular to a trenchless prefabricated fencing. Background Technology

[0002] Prefabricated construction represents a significant transformation in construction methods and is an important measure to promote supply-side structural reform and new urbanization. It is conducive to saving resources and energy, reducing construction pollution, improving labor productivity and quality and safety levels, and promoting the deep integration of the construction industry with informatization and industrialization, cultivating new industries and new driving forces, and helping to resolve overcapacity. As an important structural unit in construction projects, walls play a positive role in security and theft prevention, protecting pedestrians, vehicles, people and property, dust and noise reduction, and beautifying the city. Prefabricated walls can be used for temporary construction site walls, permanent residential and factory walls, as well as distinctive cultural walls and landscape walls.

[0003] However, when constructing prefabricated walls, it is usually necessary to first dig a trench of a certain width and depth in the ground, then place the wall panels one by one into the trench, pour concrete mortar into the trench, and finally seal the joints between the wall panels with concrete. The construction efficiency of the wall is low. Summary of the Invention

[0004] To improve the construction efficiency of the fence, this application provides a prefabricated fence that does not require excavation.

[0005] This application provides a no-excavation prefabricated fence, which adopts the following technical solution:

[0006] A prefabricated wall without excavation includes wall panels and several pile foundation units fixed to the ground. Each pile foundation unit includes a first steel pile, a second steel pile, and a fixing component. Both the first and second steel piles are driven into the ground. A fixing plate is fixedly installed on the top of both the first and second steel piles. The fixing plate is horizontally arranged, and a clamping plate is fixedly installed on the fixing plate. A clamping groove for inserting the wall panel is formed between two clamping plates located in the same pile foundation unit. The fixing component is used to fix the wall panel in the clamping groove.

[0007] By adopting the above technical solution, during the construction of the prefabricated wall, the positions of the pile foundation units are marked on the ground. At each pile foundation unit position, the first and second steel piles are driven into the ground, and the spacing between the first and second steel piles at each pile foundation unit is equal. The clamping plates on the first and second steel piles at each pile foundation unit are parallel to each other and equally spaced. Then, the wall panels are installed in the groove formed by the two clamping plates and then fixed by fixing components. Thus, when constructing the wall, there is no need to cut grooves in the ground, which greatly improves the construction efficiency.

[0008] Optionally, concrete columns are fixedly installed on the fixing plates of the first and second steel piles. The concrete columns are vertically installed and are used to be installed between two adjacent wall panels. Insertion blocks are fixedly installed on both sides of the concrete columns. Grooves for inserting the insertion blocks are provided on both sides of the wall panels. Insertion blocks on the same side of the two concrete columns located in the same pile foundation unit are inserted into the groove on one side of the wall panel.

[0009] By adopting the above technical solution, during the installation of the wall panel, the plugs on the same side of the two concrete columns of the same pile foundation unit are inserted into the groove on one side of the wall panel. When the wall panel is impacted, the wall panel tends to tilt, and applies a force to the clamping plates on the first and second steel piles, causing them to tilt to a certain extent. This increases the width of the clamping groove formed by the clamping plates, leading to loosening of the wall. However, by inserting the plugs on the two concrete columns into the groove on one side of the wall panel, the two concrete columns are prevented from moving away from each other, thereby preventing the first or second steel pile from tilting, which greatly increases the structural strength of the wall.

[0010] Optionally, multiple wall panels are stacked sequentially from bottom to top between two adjacent pile foundation units. A splicing block is fixedly provided on the bottom wall of each wall panel, and a splicing groove is provided on the top wall of each wall panel for inserting the splicing block of the next wall panel. The splicing block of the bottommost wall panel is used to insert into the groove formed by the two clamping plates of the same pile foundation unit.

[0011] By adopting the above technical solution, multiple wall panels are set between two adjacent pile foundation units, thereby reducing the volume and weight of the wall panels and facilitating their transportation. During installation, the upper and lower wall panels are spliced ​​together using splicing blocks and splicing grooves, thereby ensuring the structural strength between wall panels at the same location.

[0012] Optionally, sound insulation cotton is provided inside the splicing groove.

[0013] By adopting the above technical solution, sound insulation cotton is placed in the splicing groove to improve the sound insulation effect of the wall.

[0014] Optionally, the fixing component includes an installation sleeve and a first fixing member. The installation sleeve is used to be fitted onto two concrete columns of the same pile foundation unit, and the installation sleeve abuts against the uppermost wall panel. The first fixing member is used to fix the installation sleeve onto one of the concrete columns.

[0015] By adopting the above technical solution, after the wall panel is installed, the installation sleeve is placed on the two concrete columns of the same pile foundation unit and the installation sleeve abuts against the uppermost wall panel. Then, the installation sleeve is fixed to one of the concrete columns by the first fastener, thereby preventing the wall panel from detaching from the concrete column and completing the installation and fixing of the wall panel.

[0016] Optionally, the concrete column can be detachably mounted on a fixing plate, and the fixing plate is provided with a second fixing member for fixing the concrete column.

[0017] By adopting the above technical solution, the concrete column can be detachably connected to the first or second steel pile, which facilitates transportation. Furthermore, if the concrete column, the first or second steel pile is damaged, it can be replaced individually, reducing material costs.

[0018] Optionally, a plug-in rod is fixedly installed on the fixing plate, and the length direction of the plug-in rod is parallel to the length direction of the steel pile. The bottom end of the concrete column is provided with a plug-in groove for the plug-in rod to be inserted along the length direction of the concrete column. The second fixing member is used to prevent the plug-in rod from sliding in the plug-in groove.

[0019] By adopting the above technical solution, when installing the concrete column on the fixing plate of the first or second steel pile, the insertion rod is inserted into the insertion groove of the concrete column, which increases the bending resistance of the concrete column on the first or second steel pile, thereby further increasing the structural strength of the concrete column.

[0020] Optionally, the first and second steel piles are covered with anti-corrosion material.

[0021] By adopting the above technical solution, the first and second steel piles are coated with anti-corrosion materials, which increases the anti-corrosion performance of the first and second steel piles and effectively prevents the first or second steel piles from rusting and corroding.

[0022] Optionally, the wall panel has a cavity, which is filled with a lightweight filler material.

[0023] By adopting the above technical solution, a cavity is set inside the wall panel and filled with a lightweight filler material, thereby reducing the weight of the wall panel and facilitating its transportation and installation.

[0024] Optionally, a rib is fixedly provided on the fixing plate, and the rib is fixedly connected to the clamping plate.

[0025] By adopting the above technical solution, the structural strength of the clamping plate on the fixed plate is increased by the rib plate, which to a certain extent prevents the clamping plate from bending and deforming under force after the wall panel is impacted.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. During the construction of the prefabricated wall, the positions of the pile foundation units are marked on the ground. At each pile foundation unit position, the first steel pile and the second steel pile are driven into the ground, and the spacing between the first steel pile and the second steel pile at each pile foundation unit is equal. The clamping plates on the first steel pile and the second steel pile at each pile foundation unit are parallel to each other and equally spaced. Then, the wall panel is installed in the groove formed by the two clamping plates and then fixed by fixing components. Thus, when constructing the wall, there is no need to cut grooves in the ground, which greatly improves the construction efficiency.

[0028] 2. During the installation of the wall panel, the interlocking blocks on the same side of the two concrete columns of the same pile foundation unit are inserted into the groove on one side of the wall panel. When the wall panel is impacted, the wall panel tends to tilt, and applies a force to the clamping plates on the first and second steel piles, causing them to tilt to a certain extent. This increases the width of the clamping groove formed by the clamping plates, leading to loosening of the wall. However, by inserting the interlocking blocks on the two concrete columns into the groove on one side of the wall panel, the two concrete columns are prevented from moving away from each other, thereby preventing the first or second steel pile from tilting, which greatly increases the structural strength of the wall.

[0029] 3. Multiple wall panels are set between two adjacent pile foundation units to reduce the volume and weight of the wall panels and facilitate their transportation. During installation, the upper and lower wall panels are spliced ​​together using splicing blocks and splicing grooves to ensure the structural strength between wall panels at the same location.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a trenchless prefabricated fence. (Refer to...) Figure 1 It includes several pile foundation units 1 fixed to the ground, and wall panels 2 installed between two adjacent pile foundation units 1. Multiple wall panels 2 are stacked from bottom to top between each pair of adjacent pile foundation units 1.

[0040] Reference Figure 1 , 2 The wall panel 2 is made of concrete. The back side of the wall panel 2 is concave inward, and a steel plate 21 is embedded inside the wall panel 2. The shape of the steel plate 21 is adapted to the shape of the wall panel 2. A steel mesh 22 is also embedded inside the wall panel 2. A cavity is set inside the wall panel 2 between the steel plate 21 and the steel mesh 22. The cavity is filled with a lightweight filler material 23, which includes sponge, sound insulation cotton 27, wood chips or heat-resistant rubber material. The inward concavity on the back side of the wall panel 2 and the cavity inside the wall panel 2, filled with lightweight filler material 23, reduce the weight of the wall panel 2, making it easier to transport and install. The steel plate 21 and the steel mesh 22 reduce the impact of the reduced thickness of the wall panel 2 and the cavity on the structural strength of the wall panel 2. The cavity is set between the steel plate 21 and the steel mesh 22, which effectively prevents the cavity of the wall panel 2 from being dented due to impact.

[0041] Reference Figure 2 , 3 The bottom wall of the wall panel 2 is fixedly provided with splicing block 24, and the top wall of the wall panel 2 is provided with splicing groove 25. The splicing block 24 is adapted to the splicing groove 25. The two sides of the wall panel 2 are provided with groove 26. When the wall panels 2 located at the same position are installed, the splicing block 24 on the upper wall panel 2 is inserted into the splicing groove 25 of the lower wall panel 2, thereby increasing the structural strength between the wall panels 2 at the same position.

[0042] Reference Figure 2The splicing groove 25 is equipped with sound insulation cotton 27. Placing the sound insulation cotton 27 in the splicing groove 25 improves the sound insulation effect of the wall.

[0043] Reference Figure 4 The pile foundation unit 1 includes a first steel pile 11, a second steel pile 12, and a fixing component. The exterior of the first steel pile 11 and the second steel pile 12 are covered with anti-corrosion material, which is water-stabilized concrete. The top walls of the first steel pile 11 and the second steel pile 12 are fixedly provided with fixing plates 13. The length direction of the first steel pile 11 and the second steel pile 12 is perpendicular to their respective fixing plates 13. The side walls of the first steel pile 11 and the second steel pile 12 are also fixedly provided with multiple stiffening plates 14. The multiple stiffening plates 14 are distributed along the circumference of the first steel pile 11 or the second steel pile 12, and the stiffening plates 14 are fixedly connected to the fixing plates 13.

[0044] Reference Figure 4 A clamping plate 15 is fixedly installed on the fixing plate 13. The clamping plate 15 includes a horizontal section 151 and a vertical section 152. The horizontal section 151 is attached to the top wall of the fixing plate 13, and the vertical section 152 is perpendicular to the fixing plate 13. Ribs 131 are also fixedly installed on the fixing plate 13, and the ribs 131 are fixedly connected to the vertical section 152 and the fixing plate 13 respectively.

[0045] Reference Figure 4 , 5 When the first steel pile 11 and the second steel pile 12 are driven into the ground, the first steel pile 11 and the second steel pile 12 are kept vertical. After the first steel pile 11 and the second steel pile 12 are driven into the ground, the fixing plates 13 on the first steel pile 11 and the second steel pile 12 are kept horizontal. The vertical sections 152 of the two clamping plates 15 located in the same pile foundation unit 1 are parallel, and a groove 16 is formed between the vertical sections 152 of the two clamping plates 15. The width of the groove 16 is equal to the width of the splicing block 24. When the wall panel 2 is installed, the splicing block 24 on the bottommost wall panel 2 is inserted into the groove 16 formed by the two vertical sections 152.

[0046] Reference Figure 4 Each fixed plate 13 has a concrete column 3 fixedly installed on its top wall. The concrete column 3 is made of reinforced concrete. The top wall of the horizontal section 151 is fixedly equipped with a plug rod 17. The length direction of the plug rod 17 is perpendicular to the fixed plate 13. The bottom wall of the concrete column 3 has a plug groove along its length direction. The plug groove is compatible with the plug rod 17. The side wall of the concrete column 3 is fixed with an installation plate 31. The installation plate 31 is Z-shaped, and one end of the installation plate 31 is embedded in the concrete column 3.

[0047] Reference Figure 4The fixing plate 13 is provided with a second fixing member for fixing the concrete column 3. The second fixing member includes a bolt mounting bolt 132, which is fixed on the fixing plate 13 and its axis is perpendicular to the fixing plate 13. A nut 133 is fitted on the bolt mounting bolt 132. The mounting plate 31 has a mounting hole 311. The concrete column 3 is fitted onto the plug rod 17 through the plug groove. When the plug rod 17 is inserted into the concrete column 3, the bolt mounting bolt 132 passes through the mounting hole 311 on the mounting plate 31. When the bottom wall of the concrete column 3 abuts against the fixing plate 13, the mounting plate 31 and the fixing plate 13 are pressed tightly together. At this time, the nut 133 is fitted onto the bolt mounting bolt 132 and tightened to prevent the plug rod 17 from coming out of the plug groove, thereby fixing the concrete column 3 onto the fixing plate 13.

[0048] Reference Figure 4 , 6 Both sides of the concrete column 3 are fixedly equipped with insertion blocks 32, which are integrally formed with the concrete column 3. After the first steel pile 11 and the second steel pile 12 are installed, the concrete columns 3 on the first steel pile 11 and the second steel pile 12 are attached to each other, and the insertion blocks 32 on the two concrete columns 3 are also attached to each other. When the wall panel 2 is installed, the wall panel 2 is installed between the two pile foundation units 1, so that the insertion blocks 32 on the same side of the two concrete columns 3 located in the same pile foundation unit 1 are inserted into the groove 26 on one side of the wall panel 2. When the wall panel 2 is impacted, the wall panel 2 has a certain tendency to tilt. The force exerted on the vertical sections 152 of the clamping plates 15 on the first steel pile 11 and the second steel pile 12, causing them to tilt to a certain extent, thus widening the groove 16 formed by the vertical sections 152 of the two clamping plates 15. This leads to loosening of the wall. However, by inserting the connecting blocks 32 on the two concrete columns 3 into the groove 26 on one side of the wall panel 2, the two concrete columns 3 are prevented from moving away from each other, thereby preventing the first steel pile 11 or the second steel pile 12 from tilting, and thus greatly increasing the structural strength of the wall.

[0049] Reference Figure 7 The fixing component includes a mounting sleeve 18 and a first fixing member. One end of the mounting sleeve 18 is sealed. The interior of the mounting sleeve 18 is adapted to the cross section formed when it is attached to the two concrete columns 3. The first fixing member includes a fixing bolt 19. The side wall of the mounting sleeve 18 is fixedly provided with a through hole. The side wall of the concrete column 3 is pre-embedded with a threaded sleeve 33, which is adapted to the fixing bolt 19.

[0050] After the wall panel 2 is installed, the mounting sleeve 18 is placed on the two concrete columns 3 and made to abut against the uppermost wall panel 2. At this time, the through hole on the mounting sleeve 18 is aligned with the threaded sleeve 33 on one of the concrete columns 3. The fixing bolt 19 is then passed through the through hole and screwed into the threaded sleeve 33 to fix the mounting sleeve 18 to the concrete column 3. This prevents the wall panel 2 from detaching from the concrete column 3, thus completing the fixing of the wall panel 2.

[0051] The implementation principle of the excavation-free prefabricated wall in this application embodiment is as follows: When constructing the prefabricated wall, the setting position of the pile foundation unit 1 is marked on the ground. The concrete column 3 is fitted onto the plug rod 17 through the plug groove, and the mounting bolt 132 is passed through the mounting hole 311 of the mounting plate 31. After the bottom wall of the concrete column 3 abuts against the fixing plate 13, the nut 133 is fitted onto the mounting bolt 132 and the nut 133 is tightened to prevent the plug rod 17 from coming out of the plug groove, thereby fixing the concrete column 3 onto the first steel pile 11 or the second steel pile 12.

[0052] At each pile foundation unit 1, a first steel pile 11 and a second steel pile 12 are driven into the ground. When the first steel pile 11 and the second steel pile 12 are driven into the ground, they are kept vertical. After the first steel pile 11 and the second steel pile 12 are driven into the ground, the fixing plates 13 on the first steel pile 11 and the second steel pile 12 are kept horizontal. The vertical sections 152 of the two clamping plates 15 located in the same pile foundation unit 1 are parallel. A groove 16 is formed between the vertical sections 152 of the two clamping plates 15, which is adapted to the width of the splicing block 24 on the wall panel 2. The concrete columns 3 on the first steel pile 11 and the second steel pile 12 are attached to each other, and the plugging blocks 32 on the two concrete columns 3 are also attached to each other.

[0053] Multiple wall panels 2 are stacked sequentially from bottom to top between each pair of adjacent pile foundation units 1. The interlocking blocks 32 on the same side of the two concrete columns 3 located in the same pile foundation unit 1 are inserted into the groove 26 on one side of the wall panel 2. The splicing block 24 on the bottommost wall panel 2 is inserted into the clamping groove 16 formed by the vertical sections 152 of the two clamping plates 15. The splicing block 24 on the upper wall panel 2 is inserted into the splicing groove 25 of the lower wall panel 2. After the wall panels 2 on both sides of the same pile foundation unit 1 are installed, the installation sleeve 18 is fitted onto the two concrete columns 3 of the pile foundation unit 1. The mounting sleeve 18 is placed on the column 3 and abuts against the uppermost wall panel 2. At this time, the fixing bolt 19 is passed through the through hole and screwed into the screw sleeve 33 to fix the mounting sleeve 18 on the concrete column 3. Thus, the mounting sleeve 18 prevents the wall panel 2 from detaching from the concrete column 3, thereby completing the fixing of the wall panel 2 and completing the construction of the prefabricated fence. Therefore, when constructing the fence, there is no need to cut grooves in the ground, saving labor and greatly improving construction efficiency. Moreover, the prefabricated fence of this application can be reused, saving costs and resources, and is highly practical.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
