Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to an assembled supporting device. Background Art

[0002] At present, due to geographical restrictions, when constructing underground pipelines in cities and towns, it is impossible to use slope excavation as the construction method. Therefore, during construction, the trenches need to be excavated and supported vertically at the same time. However, due to factors such as geological conditions, the trenches dug during construction will also be restricted, resulting in the inability to smoothly install the support devices, causing safety hazards.

[0003] Existing support methods for trench excavation include plate support, channel steel support, steel sheet pile support, support piles, etc. However, when there are underground pipelines or boulders or rock formations that cannot be relocated in the construction area, traditional support methods cannot be embedded in the corresponding soil, resulting in failure of the support form. For boulders and rock formations, a common treatment method is to drill holes, but the cost of drilling holes is high and uneconomical. Utility Model Content

[0028] Below, in conjunction with specific implementation methods, the utility model is further described:

[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0031] like Figure 1-6 An assembled support device shown includes a plurality of pillars 10, a baffle 30 and an adjustable cross brace 20. The plurality of pillars 10 extend along a first direction, and each two adjacent pillars 10 are arranged side by side and spaced apart along a second direction. The baffle 30 is arranged between each two adjacent pillars 10 along the first direction, and both ends of the baffle 30 are respectively connected to the two adjacent pillars 10 along the first direction. The adjustable cross brace 20 is arranged between the two adjacent pillars 10 along the second direction, and one end of the adjustable cross brace 20 is connected to one of the pillars 10, and the other end of the adjustable cross brace 20 is connected to the other pillar 10. The adjustable cross brace 20 is used to adjust the spacing distance between the two adjacent pillars 10.

[0032] Based on the above structure, the first direction is the extension direction of multiple pillars 10, and the second direction perpendicular to the first direction is the axial direction of the adjusting cross brace 20. During assembly, the two pillars 10 can be first connected together in the first direction through the baffle 30, so that the two side-by-side pillars 10 and the baffle 30 form a whole. Then, the two side-by-side baffles 30 and the pillars 10 after splicing are respectively arranged close to the inner wall of the groove along the second direction. Finally, they are connected to the pillars 10 on both sides one by one through adjustment to form a support, and the baffles 30 and the pillars 10 on both sides are used to prevent the groove from collapsing.

[0033] The existing support method used for trench excavation cannot be embedded in the corresponding soil when there are underground pipelines or boulders or rock formations that cannot be relocated in the construction area, resulting in failure of the support form. Usually, the common treatment method for boulders and rock formations is to drill holes, but the cost of drilling holes is high.

[0034] Therefore, when using the assembled support device in this embodiment, the pillars 10 and the baffles 30 are first assembled next to the trench or foundation pit. For the assembly, the pillars 10 can be placed vertically first, and then the baffles 30 are respectively connected between the two vertically placed pillars 10. After the assembly is completed, multiple groups of assembled baffles 30 and pillars 10 are placed on both sides of the trench, and then each two pillars 10 opposite to each other are connected by adjusting the cross brace 20. During the assembly process, the cross brace 20 can be adjusted in real time until the pillars 10 and the baffles 30 on both sides are close to the soil on both sides of the trench, so as to make the entire support structure more stable.

[0035] More specifically, since the width of the cross brace 20 is always adjustable, when the trench to be excavated is too wide or too narrow, the spacing distance between the two side pillars 10 can be changed by adjusting the width of the adjustable support, so that it can be applied to trenches of different terrains, has a wide range of applications, and does not require additional holes to be opened. The operation is simple and flexible, and is economical and practical.

[0036] It should be noted that the baffle 30 and the adjustable cross brace 20 in this embodiment can be detachably connected to the pillar 10 by means of a snap connection or a threaded connection, so as to facilitate disassembly and assembly at any time. In addition, the baffle 30 and the adjustable cross brace 20 can be made of materials with high supporting strength, such as steel plates, alloy plates, etc.; and the adjustable cross brace 20 can be formed by structures such as telescopic tubes or stretchable elastic parts.

[0037] Furthermore, the adjusting cross brace 20 includes an adjusting member and at least two connecting tubes 21, one end of each two adjacent connecting tubes 21 is connected to two adjacent pillars 10 along the second direction, and the other end of each two adjacent connecting tubes 21 is connected via an adjusting member, one end of the adjusting member is rotatably installed in one of the connecting tubes 21, and the other end of the adjusting member is rotatably installed in the other connecting tube 21, and the adjusting member is used to move along the axial direction of the two connecting tubes 21 when rotated by force, and move closer to or away from the two connecting tubes 21, so as to adjust the distance between the two adjacent connecting tubes 21.

[0038] On the basis of this structure, the adjusting cross brace 20 in this embodiment is assembled by at least two connecting tubes 21 and an adjusting piece. During assembly, the two ends of the adjusting piece can be rotatably connected to the two connecting tubes 21, and then connected to the two side-by-side pillars 10 through the two connecting tubes 21. When it is necessary to adjust the spacing distance between the two pillars 10, it is only necessary to apply external force to rotate the adjusting piece. When the adjusting piece is rotated to move close to the two connecting tubes 21, the spacing distance between the two connecting tubes 21 also becomes closer. At this time, the length of the adjusting cross brace 20 in the second direction becomes shorter, which can shorten the spacing distance between the two pillars 10, so it is suitable for use in terrain with relatively narrow grooves.

[0039] When it is used in terrain with relatively wide grooves, the adjusting member can be rotated in the reverse direction again so that it can move away from the connecting pipes 21 at both ends respectively, so as to lengthen the spacing distance between the two connecting pipes 21. At this time, the axial length of the cross brace 20 in the second direction is adjusted to be longer to synchronously widen the spacing distance between the two pillars 10, which is suitable for use in terrain with relatively wide grooves.

[0040] It should be noted that the connecting tube 21 in this example can be formed by a hollow steel tube or other types of metal tubes, and the adjusting member is a rotatable columnar or rod-shaped structure, so that its two ends can be rotatably inserted into the connecting tubes 21 at both ends respectively. When rotating, the adjusting member can extend into or out of the connecting tube 21 to move closer to or away from the two connecting tubes 21, thereby achieving the effect of adjusting the length of the cross brace 20.

[0041] In addition, the number of the connecting tubes 21 can be two, three or more, and can be increased or decreased according to the required length of the adjusting cross brace 20 . When each connecting tube 21 is added, the adjusting member can be increased accordingly.

[0042] Furthermore, the adjusting member is a screw rod 22 , and a threaded hole is provided on the inner wall of one end of each of two adjacent connecting tubes 21 close to the adjusting member. The screw rod 22 is connected to the threaded hole and threadably cooperates with the threaded hole, so that the adjusting member can move axially along the two connecting tubes 21 .

[0043] Specifically, the adjusting member in this embodiment is a screw rod 22, and a threaded hole is provided on the inner wall of each adjacent connecting tube 21. The screw rod 22 is threadedly matched with the threaded hole so that the screw rod 22 can be more closely matched with the connecting tube 21 during rotation, the connection between the two is not easy to loosen, and the whole structure is more stable.

[0044] Preferably, the screw rod 22 can be selected from existing trapezoidal screw rods 22, rectangular screw rods 22 or sawtooth screw rods 22, etc. The thread in the specific connecting rod can be integrally formed or machined later.

[0045] Furthermore, an adjusting nut 23 is sleeved on one end of each of two adjacent connecting tubes 21 close to the adjusting member, a threaded hole is provided in the adjusting nut 23 , and both ends of the screw rod 22 are respectively connected to the two connecting tubes 21 through the two adjusting nuts 23 .

[0046] Specifically, during the long-term use of the horizontal adjustment, the screw rod 22 or the threaded hole may be worn, or the threaded hole is directly set in the connecting tube 21. When it is replaced and repaired later, the whole tube needs to be replaced, which is inconvenient to maintain and the maintenance cost is relatively high. Therefore, in this embodiment, the outer periphery of each two adjacent connecting tubes 21 can be penetrated by an adjusting nut 23, and the threaded hole is set in the adjusting thread. During assembly, the two adjusting nuts 23 are respectively sleeved on the outer periphery of the two connecting tubes 21, and then the two ends of the screw rod 22 are respectively screwed into the threaded holes in the adjusting nut 23. Compared with the method of setting threads in the connecting tube 21, when the threaded hole or the screw rod 22 is worn later, it is only necessary to replace the adjusting nut 23 or the screw rod 22, and there is no need to replace the connecting tube 21, which is convenient for later maintenance and the maintenance cost is relatively low.

[0047] Preferably, the adjusting nut 23 can be selected from existing hexagonal nuts or octagonal nuts.

[0048] Furthermore, at least two connecting tubes 21 are provided with connecting heads 24 on one end close to the pillar 10, at least two pillars 10 are provided with connecting disks 11, and the connecting disks 11 are provided with insertion ports, and the connecting heads 24 are inserted into the insertion ports.

[0049] Specifically, a connector 24 is provided on the connecting tube 21. During assembly, the connector 24 can be inserted into the insertion port on the connecting plate 11 on the pillar 10, so that the connecting tube 21 is engaged and connected with the pillar 10, which is convenient for assembly and disassembly.

[0050] It should be noted that the connecting head 24 and the connecting plate 11 can be connected to the connecting pipe 21 and the pillar 10 respectively by welding, so that the connection between the adjustable cross brace 20 and the pillar 10 is not easy to break after assembly; of course, the connecting plate 11 can also be set on the connecting pipe 21 and the connecting head 24 can be set on the pillar 10.

[0051] In another embodiment, an insertion port can be directly provided on the pillar 10, and the connecting pipe 21 can be directly inserted into the insertion port. However, in this manner, the internal structure of the pillar 10 may be damaged by drilling, resulting in a decrease in its bearing capacity. The overall load-bearing capacity is weakened, and it is easy to collapse after bearing the load, resulting in a decrease in the safety of the entire support device. Therefore, this embodiment adopts the method of providing a connector 24 on the pillar 10 to connect the connecting pipe 21, and the structure is more stable.

[0052] Furthermore, a plurality of adjusting cross braces 20 are provided, and each two adjacent pillars 10 are connected by a plurality of adjusting cross braces 20 , and the plurality of adjusting cross braces 20 are arranged at intervals along the axial direction of the pillars 10 .

[0053] Based on the above structure, a plurality of adjustable cross braces 20 are provided. During assembly, the adjustable cross braces 20 can be arranged at intervals along the axial direction of the pillars 10 and connected between two side-by-side pillars 10 along the second direction. In this way, the two pillars 10 are connected by a plurality of adjustable cross braces 20, and the structure is relatively more stable.

[0054] During specific assembly, an adjustable cross brace 20 can be set at the top and bottom of the pillar 10 to ensure that the pillar 10 is supported from top to bottom and is not easy to collapse. The specific number of adjustable supports can be set according to the axial length of the pillar 10, and can be set to three or four, etc.

[0055] More specifically, in this embodiment, a plurality of baffles 30 are provided, and the plurality of baffles 30 are sequentially fitted from top to bottom along the axial direction of the pillar 10, so that the baffles 30 can be arranged one by one along the axial direction of the pillar 10, so as to enclose two adjacent pillars 10 in a first direction to form a plate-like structure, so that the support area on both sides of the entire structure is larger and the use process is safer.

[0056] Compared with installing the baffle 30 between two pillars 10 using a whole plate, the implementation method in this embodiment can flexibly adjust the supporting area according to the specific length of the pillar 10, and is applicable to a wider range of scenarios.

[0057] During assembly, a plurality of pillars 10 are provided with card interfaces 12, and a plurality of baffles 30 are provided with card connection parts on their peripheries. The plurality of baffles 30 can be respectively carded into the plurality of pillars 10 through the card connection parts so that the two are carded and connected, which is convenient for later disassembly and assembly.

[0058] It should be noted that the snap-fitting portion may be formed by bending the edge of the baffle 30 , or may be a sheet-shaped structure directly processed later so that it can be snap-fitted into the card interface 12 .

[0059] Furthermore, the present invention further comprises a plurality of connecting columns 40 , and both ends of the plurality of connecting columns 40 are sequentially connected to every two adjacent pillars 10 along the first direction.

[0060] On the basis of this structure, in order to strengthen the connection structure of the two pillars 10 in the first direction, after the baffle 30 and the pillar 10 are assembled, a connecting column 40 can also be installed between the two connecting columns 40. The connecting column 40 makes the entire structure more stable and has greater load-bearing capacity.

[0061] Specifically, one, two or more connecting columns 40 can be set between every two pillars 10 in the first direction, and the connecting columns 40 can also be formed by existing steel pipes, alloy pipes or other high-strength and corrosion-resistant metal pipes. The specific number can be designed according to actual needs to enhance the stability of the entire structure.

[0062] In addition, a plurality of connecting columns 40 are provided with a card joint 41, and a plurality of pillars 10 are provided with a card slot. The plurality of card slots and the plurality of card joints 41 are arranged in a one-to-one correspondence. During assembly, the plurality of connecting columns 40 can be connected to the card slot through the card joint 41, so that the connecting columns 40 and the pillars 10 can be detachably connected, which is convenient for later disassembly and assembly.

[0063] Specifically, the clamping joint 41 can be welded or integrally formed on the connecting column 40 to form a sheet or block structure, and the clamping groove can also be mechanically cut or integrally formed on the pillar 10.

[0064] More specifically, in order to make the structure of the entire prefabricated support device more stable after assembly, after the adjustable cross brace 20, the baffle 30 and the pillar 10 are assembled, the lateral distance between each side-by-side pillar 10 is measured, and concrete pads are prefabricated on site according to the actual width (the pads can also be cast on the formwork on both sides of the pillar 10) to make the structure more stable. After prefabrication (cast-in-place) is completed, the bottom adjustable cross brace 20 is removed, and the pipeline is moved in for installation and backfilling. When backfilling to the position of the top adjustable cross brace 20 and the connecting column 40, the adjustable cross brace 20 and the connecting column 40 are removed. After the backfilling is completed, the pillar 10 and the baffle 30 are pulled out, and the construction is completed.

[0065] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
