Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a crash-proof safety fence for building construction. Background Technology

[0002] During the construction of various engineering projects such as building construction and water conservancy projects, protective fences are usually set up around the construction site. On the one hand, this isolates the construction area from the surrounding environment to prevent unauthorized personnel from entering the construction site. On the other hand, it reduces the impact of dust, noise, sewage and other pollutants generated during construction on the surrounding environment. In case of an accident, it also dissipates the kinetic energy of a vehicle collision and provides protection for the construction workers inside.

[0003] There is a prefabricated fence in the existing technology, which consists of columns, diagonal braces and baffles. The installation process includes: fixing the columns to the ground or precast concrete blocks with expansion bolts, fixing the diagonal braces to the ground and connecting the diagonal braces to the columns, and then installing the baffles between the two columns from bottom to top. In the above fence installation process, the baffles and columns need to be installed with self-tapping screws. However, since the fence is a reusable device, with the increase of the number of uses, the number of holes for fastening with self-tapping screws on the baffles and columns will increase accordingly, affecting the structural strength of the baffles and columns. Summary of the Invention

[0004] This invention provides a crash-proof safety fence for construction, which overcomes the disadvantage that the strength of the baffle and column structure decreases after repeated use of existing fences.

[0005] The technical solution is as follows: a construction safety fence, comprising: several posts; baffles evenly distributed between adjacent posts; two symmetrically distributed side plates fixed to the baffles; locking elements slidably connected to the side plates; connecting strips fixed to the locking elements; positioning bolts located on the connecting strips away from the corresponding locking elements; two main locking holes on the side plates; the positioning bolts passing through the corresponding main locking holes; two symmetrically distributed locking grooves and two symmetrically distributed clearance grooves on the posts; the clearance grooves communicating with and located above the corresponding locking grooves; the clearance grooves allowing the corresponding locking elements to enter the corresponding posts; the width of the locking grooves being less than the maximum width of the locking elements; two symmetrically distributed limiting blocks detachably connected to the upper part of the posts; and two symmetrically distributed support blocks fixed to the lower part of the posts; the limiting blocks and support blocks respectively limiting the extreme positions of the corresponding baffles.

[0006] Furthermore, the baffle is provided with a support portion and a locking portion. The support portion, the locking portion, and the two side plates are respectively located at the four edges of the corresponding baffle. The support portion is used to limit the corresponding locking portion on different baffles. Two symmetrically distributed adjusting members are slidably connected within the support portion for limiting. An elastic member is fixed between the two adjusting members on the same support portion. A T-shaped member is fixed to the side of the two corresponding adjusting members on the same baffle away from the corresponding locking portion. The T-shaped member is slidably connected to the corresponding support portion for limiting. Two symmetrically distributed shifting grooves and two symmetrically distributed fitting grooves are provided on the side of the locking portion on the same baffle away from the corresponding support portion. The shifting grooves are used to allow the T-shaped members corresponding to different baffles to enter the corresponding locking portion. The groove width of the fitting groove is less than the maximum width of the T-shaped member. The T-shaped member limits the two corresponding baffles through the corresponding fitting grooves on different baffles.

[0007] Furthermore, on the same baffle, a positioning protrusion is provided on the side of the support portion away from the corresponding baffle and the corresponding locking portion, and the positioning protrusion is used to abut against the corresponding locking portion on different baffles.

[0008] Furthermore, on the same baffle, two symmetrically distributed reinforcing ribs are provided on the side of the fitting groove near the support portion, and two symmetrically distributed grooves are provided on the T-shaped member. The grooves of the T-shaped member match the shapes of the corresponding reinforcing ribs on different baffles, and the grooves of the T-shaped member are used to limit the positions of the corresponding reinforcing ribs on different baffles.

[0009] Furthermore, two symmetrically distributed guide portions are provided on the opposite sides of the two T-shaped pieces corresponding to the same support portion, and the guide portions are used to guide the T-shaped pieces into the corresponding fitting grooves.

[0010] Furthermore, the maximum distance between the two side plates on the same baffle is equal to the minimum distance between the limiting block and the supporting block on the same side of the same column. The opposing sides of the limiting block and the supporting block on the same side of the column are provided with secondary locking holes. The secondary locking holes are used to place locking pins, and the locking pins are used to limit the corresponding side plates through the corresponding main locking holes.

[0011] Furthermore, the connecting strip is provided with equidistantly distributed positioning holes, the positioning bolt passes through the corresponding positioning hole, and a fixing strip is hinged to the side of the connecting strip near the corresponding positioning bolt. The fixing strip is provided with a strip-shaped hole, and the column is fixedly connected with a positioning member. All the positioning bolts are used to limit the connecting strip and the positioning member to the corresponding fixing strip on different baffles.

[0012] Furthermore, a compression spring is fixedly connected to the fixing strip at a position away from the hinge point with the corresponding connecting strip, and two grooves are provided on the side of the locking part near the corresponding compression spring. The compression spring limits the corresponding fixing strip through the grooves on the locking part.

[0013] Furthermore, the positioning elements on two adjacent columns are respectively located at the upper and lower positions of the corresponding columns.

[0014] Furthermore, in the direction that gradually moves away from the corresponding baffle, the distance between the side plate and the corresponding support and the corresponding locking part gradually increases.

[0015] Those skilled in the art will understand that the present invention has at least the following beneficial effects: The present invention uses the relative state of the locking member and the positioning bolt with the locking groove to restrict the movement of the baffle and the column in the horizontal direction, and uses the limiting block and the support block to restrict the movement of the baffle and the column in the vertical direction. In this way, a stable connection between the baffle and the column can be achieved without self-tapping screws, eliminating the influence of self-tapping screw holes on the structural strength of the enclosure.

[0016] By changing the installation of the baffles from horizontal to vertical, and by causing elastic deformation at the connection between the support and locking parts and the corresponding baffles after the two baffles are spliced ​​together, the two adjacent baffles can be relatively deflected. In this way, the number of baffles and the deflection angle of the two adjacent baffles can be set according to the shape of the construction area, so that the fence can adapt to the shape of the construction area, reduce the area occupied by the construction area, and reduce the impact of the fence on the surrounding traffic.

[0017] By connecting and fixing the connecting strips, fixing strips and positioning parts with positioning bolts, two adjacent baffles and columns are connected to the corresponding baffles as a whole, which enhances the structural strength of the curved part of the fence and improves the structural stability of this part.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1 This embodiment provides a construction safety fence to address the problem that the structural strength of the barriers and columns decreases after repeated use of existing fencing.

[0022] It should be noted that since the diagonal bracing in the enclosure is an existing part, it is not shown in the accompanying drawings of this application; in this embodiment, the baffle 2 is always installed horizontally.

[0023] See Figures 1 to 7 A construction safety fence includes: several posts 1, each post 1 having holes on its lower side for expansion bolt connections; equidistant baffles 2 between adjacent posts 1; two symmetrically distributed side plates 3 fixedly connected to each baffle 2; a locking element 4 slidably connected to the center of each side plate 3; the locking element 4 consisting of a disc and a connecting rod; and receiving grooves for accommodating the corresponding locking elements 4 in the center of the opposite sides of the two side plates 3 of the same baffle 2 (see attached diagram). Figure 6 The locking element 4 is designed to be coplanar with the side of the corresponding side plate 3, facilitating the insertion of the baffle 2 between the two columns 1. Connecting strips 5 are fixed to the opposing sides of the two locking elements 4 corresponding to the same baffle 2. Positioning bolts 6 are installed on the connecting strips 5 away from the corresponding locking element 4. The side plate 3 has two main locking holes 301, through which the positioning bolts 6 pass. The column 1 has two symmetrically distributed locking grooves 401 and two symmetrically distributed clearance grooves 402. The clearance grooves 402 communicate with the corresponding locking grooves 401 and are located above the corresponding locking grooves 401. The clearance grooves 402 are used for… The corresponding locking element 4 is inserted into the corresponding column 1. The width of the clearance groove 402 is not less than the diameter of the disc of the locking element 4. The diameter of the connecting rod of the locking element 4 and the diameter of the threaded part of the positioning bolt 6 are equal to the width of the locking groove 401. Two symmetrically distributed limiting blocks 7 are detachably connected to the upper part of the column 1. Two symmetrically distributed support blocks 8 are fixed to the lower part of the column 1. The limiting blocks 7 and the support blocks 8 are used to limit the upper and lower limit positions of the corresponding baffles 2, respectively. When the limiting blocks 7 limit the corresponding baffles 2, the horizontal height of all locking elements 4 on the same column 1 is lower than the horizontal height of the clearance groove 402.

[0024] The above setup enables the relative state of the locking element 4 and the positioning bolt 6 with the locking groove 401 to restrict the horizontal movement of the baffle 2 and the column 1, and to restrict the vertical movement of the baffle 2 and the column 1 with the limiting block 7 and the support block 8. In this way, a stable connection between the baffle 2 and the column 1 can be achieved without self-tapping screws, eliminating the impact of self-tapping screw holes on the structural strength of the enclosure.

[0025] It should be noted that in this embodiment, the connection between the connecting strip 5 and the corresponding positioning bolt 6 can be understood as a fixed connection.

[0026] See Figures 5 to 12The baffle 2 is provided with a support part 9 and a locking part 10. The support part 9, the locking part 10, and the two side plates 3 are respectively located at the four edges of the corresponding baffle 2. The baffle 2, the two corresponding side plates 3, the corresponding support part 9, and the corresponding locking part 10 are all bent from the same piece of metal sheet. The bent ends of the support part 9 and the locking part 10 are connected to the corresponding baffle 2 by spot welding. The support part 9, the locking part 10, and the side plates 3 are used to enhance the bending strength of the baffle 2 in the horizontal and vertical directions. The support part 9 is used to limit the corresponding locking part 10 on different baffles 2. Two symmetrically distributed adjusting parts 11 are slidably connected in the limiting part 9. An elastic element 12 is fixed between the two adjusting parts 11 on the same support part 9. The elastic element 12 is a clip spring. On one baffle 2, two corresponding adjusting members 11 are fixedly connected to a T-shaped member 13 on the side away from the corresponding locking part 10. A rectangular groove is provided on the support part 9 near the corresponding T-shaped member 13. The T-shaped member 13 passes through the rectangular groove of the corresponding support part 9 and is slidably connected to it. On the side away from the corresponding support part 9, the locking part 10 on the same baffle 2 is provided with two symmetrically distributed shifting grooves 131 and two symmetrically distributed fitting grooves 132. The width of the shifting groove 131 is not less than the maximum width of the T-shaped member 13. The shifting groove 131 is used to allow the corresponding T-shaped members 13 on different baffles 2 to enter the corresponding locking part 10. The width of the fitting groove 132 is equal to the minimum width of the T-shaped member 13. The T-shaped member 13 limits the corresponding two baffles 2 through the corresponding fitting grooves 132 on different baffles 2.

[0027] The above configuration enables the T-shaped piece 13 to be fitted into the fitting groove 132, thereby connecting two adjacent baffles 2 into one unit. Individual baffles 2 have the advantage of being easy to transport. After installation, the interconnected baffles 2 can enhance the overall strength of the enclosure.

[0028] See Figure 5 , Figure 8 and Figure 12 On the same baffle 2, a positioning protrusion 901 is provided on the side of the support part 9 away from the corresponding baffle 2 and the corresponding locking part 10. The positioning protrusion 901 is used to abut against the corresponding locking part 10 on the different baffle 2 when the corresponding T-shaped piece 13 has not entered the corresponding locking part 10 on the different baffle 2, so that after the T-shaped piece 13 moves, it can directly enter the corresponding transfer groove 131 on the different baffle 2.

[0029] Fence assembly process: Determine the position of all columns 1 according to the edge of the construction area, fix all columns 1 to the ground one by one with expansion bolts, install diagonal braces, and make the distance between the locking grooves 401 on the opposite side of two adjacent columns 1 equal to the maximum distance between the two side plates 3 on the same baffle 2. After the columns 1 are installed, remove the limiting blocks 7 on the columns 1, and then install the baffle 2.

[0030] Push the locking member 4 so that the disc of the locking member 4 enters the receiving groove of the corresponding side plate 3. Then lift the baffle 2 until the locking member 4 corresponds to the clearance groove 402. At this time, push the locking member 4 so that the disc of the locking member 4 enters the clearance groove 402. At the same time, the locking member 4 drives the positioning bolt 6 into the locking groove 401 through the connecting bar 5. Move the baffle 2 downward so that the connecting rod of the locking member 4 and the positioning bolt 6 slide downward along the locking groove 401 together until the support part 9 abuts against the two support blocks 8. The installation of the lowermost baffle 2 is completed. Then repeat the above steps to start installing the second baffle 2.

[0031] During the installation of the two adjacent baffles 2, the two T-shaped pieces 13 corresponding to the second baffle 2 abut against the upper side of the lower locking part 10. At this time, the positioning protrusion 901 abuts against the side of its lower locking part 10. The operator moves the two adjusting pieces 11 closer to each other and compresses the elastic piece 12, so that the adjusting pieces 11 drive the corresponding T-shaped pieces 13 to move and gradually correspond to the supply groove 131. At this time, under the gravity of the baffle 2, the baffle 2 drives the T-shaped pieces 13 to move down through the support part 9 and the adjusting pieces 11, so that the T-shaped pieces 13 enter the locking part 10 below it. At this time, the two adjusting pieces 11 are released, and the two adjusting pieces 11 move away from each other under the elastic force of the elastic piece 12. The fitting groove 132 and the reinforcing rib 133 are both fitted with the T-shaped pieces 13. Thus, the two adjacent baffles 2 are connected as one.

[0032] Repeat the above steps to install five baffles 2 from bottom to top. Then reinstall the limiting block 7 onto the column 1 so that the limiting block 7 abuts against the locking part 10 of the uppermost baffle 2, restricting the movement of the baffle 2 in the vertical direction.

[0033] The process for removing the construction site fence is to simply repeat the steps described above.

[0034] Example 2 This embodiment is a further optimization based on Embodiment 1.

[0035] See Figure 11 and Figure 12 On the same baffle 2, two symmetrically distributed reinforcing ribs 133 are provided on the side of the fitting groove 132 near the support part 9. The T-shaped piece 13 is provided with two symmetrically distributed grooves. The grooves of the T-shaped piece 13 match the shapes of the corresponding reinforcing ribs 133 on different baffles 2. When the T-shaped piece 13 is fitted with the corresponding fitting grooves 132 on different baffles 2, the reinforcing ribs 133 are located in the corresponding grooves of the corresponding T-shaped pieces 13 on different baffles 2. The grooves of the T-shaped piece 13 are used to limit the position of the corresponding reinforcing ribs 133 on different baffles 2.

[0036] The above configuration enables the T-shaped part 13, the reinforcing rib 133, and the fitting groove 132 to be connected as a whole by the fitting of the groove of the T-shaped part 13 and the reinforcing rib 133, thereby improving the structural strength of the fitting groove 132 when subjected to tensile force between the two baffles 2.

[0037] See Figure 11 and Figure 12 Two symmetrically distributed guide portions 134 are provided on the opposite sides of the two T-shaped pieces 13 corresponding to the same support portion 9. Each guide portion 134 consists of three guide slopes. The guide portion 134 is used to guide the T-shaped piece 13 into the corresponding fitting groove 132 on different baffles 2 and guide the reinforcing rib 133 into the corresponding groove of the T-shaped piece 13 on different baffles 2.

[0038] Example 3 This embodiment is a further optimization based on embodiment 2, enabling the fence to adapt to the irregular shape of the construction area, reducing the land area occupied by the urban construction area, and improving the ease of installation of the fence at corner positions.

[0039] It should be noted that in this embodiment, the baffle 2 can be installed both horizontally and vertically.

[0040] See Figures 1 to 6 The maximum distance between the two side plates 3 on the same baffle 2 is equal to the minimum distance between the limiting block 7 and the support block 8 on the same side of the same column 1. That is, when the baffle 2 is installed vertically, the two side plates 3 on the baffle 2 abut against the corresponding limiting block 7 and the corresponding support block 8 respectively. The opposing sides of the limiting block 7 and the support block 8 on the same side of the column 1 are provided with secondary locking holes 701. The secondary locking holes 701 are used to place the locking pin 14, and there is friction between the locking pin 14 and the secondary locking hole 701, so that the locking pin 14 can remain stable in the corresponding secondary locking hole 701. The locking pin 14 is used to limit the corresponding side plate 3 through the corresponding main locking hole 301. The baffle 2 is made of a flexible metal material, such as stainless steel.

[0041] The above setup enables the following: by changing the installation of the baffle 2 from horizontal to vertical, and after the two baffles are spliced ​​together, the connection between the support part 9 and the locking part 10 and the corresponding baffle 2 undergoes elastic deformation, causing relative deflection between the two adjacent baffles 2. Thus, the number of baffles 2 and the deflection angle between the two adjacent baffles 2 can be set according to the shape of the construction area, thereby allowing the fence to adapt to the shape of the construction area, reducing the area occupied by the construction area, and reducing the impact of the fence on the surrounding traffic.

[0042] See Figures 2 to 7 and Figure 13The connecting strip 5 has six equidistantly distributed positioning holes 501. The positioning bolt 6 passes through the positioning hole 501 closest to the support part 9. The connecting strip 5 is hinged to a fixing strip 15 on the side close to the corresponding positioning bolt 6. The positioning bolt 6 abuts against the corresponding fixing strip 15 to keep the relative position of the positioning bolt 6 and the corresponding connecting strip 5 stable when the baffle 2 is installed horizontally. The fixing strip 15 has a strip-shaped hole 151. The column 1 is fixedly connected to a positioning element 16. The positioning bolt 6 and the nut are used together to limit the connecting strip 5 to the corresponding fixing strip 15 on different baffles 2 or the positioning element 16 to the corresponding fixing strip 15.

[0043] The above setup enables the connecting strip 5, fixing strip 15 and positioning element 16 to be connected and fixed by positioning bolt 6, so that two adjacent baffles 2 and columns 1 are connected to the corresponding baffles 2 as a whole, thereby enhancing the structural strength of the curved part of the enclosure and improving the structural stability of this part.

[0044] See Figure 14 A compression spring 17 is fixed to the fixing strip 15 away from the hinge point with the corresponding connecting strip 5. The compression spring 17 is made of elastic metal. The locking part 10 has two grooves on the side near the corresponding compression spring 17. The two grooves are used to restrict the corresponding fixing strip 15 to two positions by the corresponding compression spring 17. One is the position of the corresponding fixing strip 15 when the locking member 4 is in the corresponding receiving groove, and the other is the position of the corresponding fixing strip 15 when the locking member 4 is not in the corresponding receiving groove. The compression spring 17 limits the corresponding fixing strip 15 by the groove on the corresponding locking part 10. By limiting the fixing strip 15 by the compression spring 17, the relative positions of the fixing strip 15, connecting strip 5 and positioning bolt 6 can be kept stable when the baffle 2 is installed horizontally, and the free movement of the fixing strip 15 can be avoided from affecting the assembly process of the enclosure.

[0045] See Figure 13 The positioning pieces 16 on the two adjacent columns 1 are respectively located at the upper and lower positions of the corresponding columns 1. That is, the upper and lower fixing strips 15 corresponding to the baffle 2 on the curved part of the fence are respectively connected to the corresponding connecting strips 5 on the same side of the two adjacent baffles 2. The upper and lower fixing strips 15 corresponding to the baffle 2 on the edge of the curved part of the fence are respectively connected to the corresponding connecting strips 5 and the corresponding positioning pieces 16 on the same side of the adjacent baffle 2. In this way, not only can the two adjacent ones be connected and fixed to each other, but the baffle 2 can also be connected and fixed to the column 1, thereby enhancing the strength of the curved part of the fence.

[0046] See Figure 8 and Figure 9In the direction that gradually moves away from the corresponding baffle 2, the distance between the side plate 3 and the corresponding support part 9 and the corresponding locking part 10 gradually increases, which provides space for the support part 9 and the locking part 10 to deflect relative to the baffle 2. At the same time, it restricts the bending position of the baffle 2 to the strip-shaped parts where the support part 9 and the locking part 10 are respectively connected to the corresponding baffle 2, so that the connection state of the two adjacent baffles 2 is similar to that of a hinge, which provides space for the deformation of the baffle 2 while ensuring the bending strength of the baffle 2.

[0047] Installation process of the curved section of the fence: Determine the number of baffles 2 required for the curved section of the fence according to the shape of the construction area (this article uses five as an example) and the position of the columns 1 at both ends of the curved section of the fence; then fix the columns 1 at both ends of the curved section of the fence, raise the baffles 2 and swing the fixing strip 15 so that the side of the fixing strip 15 is no longer in contact with the side of the corresponding connecting strip 5. At this time, remove the positioning bolts 6 from the positioning holes 501 and the corresponding main locking holes 301, and rotate the connecting strip 5 with the axis of the locking part 4 as the axis of rotation; adjust the position of the baffles 2 so that the two main locking holes 301 on both sides of the length direction of the baffles 2 correspond to the secondary locking holes 701 of the upper limit block 7 and the secondary locking holes 701 of the support block 8 of the adjacent column 1, and insert the locking pins 14 into the two main locking holes 301 respectively, and use the locking pins 14 to connect the main locking holes 301 with the corresponding secondary locking holes 701. At this time, the connection between the baffles 2 and the columns 1 is completed.

[0048] Similar to the steps in Embodiment 1 above, where two baffles 2 are connected as one unit using T-shaped piece 13, two adjacent baffles 2 are connected as one unit until five baffles 2 are connected to each other. Then, the five baffles 2 connected as one unit are bent as a whole until the two main locking holes 301 on the end baffle 2 correspond one-to-one with the two corresponding secondary locking holes 701 on the same side of another column 1. Then, the two locking posts 14 are simultaneously inserted into the main locking holes 301 and the corresponding secondary locking holes 701, thus realizing the connection of the bent part of the enclosure.

[0049] The steps for connecting two adjacent baffles 2 and the column 1 to the corresponding baffle 2 using the connecting strip 5, positioning bolt 6, fixing strip 15 and positioning element 16 are as follows: the connecting strip 5 is swung around the axis of the locking element 4 until the strip hole 151 corresponds to a positioning hole 501 on a non-adjacent baffle 2. At this time, the positioning bolt 6 is passed through the positioning hole 501 and the strip hole 151, and the nut is used to connect the positioning bolt 6 to the connecting strip 5 and the corresponding fixing strip 15. The steps for connecting the positioning element 16 to the fixing strip 15 are the same.

Although the present invention 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 of the technical features.
