Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for Larssen sheet piles, specifically a support structure for Larssen sheet piles. Background Technology

[0002] Larssen sheet piles, also known as U-shaped sheet piles, are a new type of building material that plays an important role in construction, such as retaining walls, water barriers, and sand barriers during bridge cofferdam construction, large pipeline laying, and temporary ditch excavation. The supporting structure is responsible for resisting lateral earth pressure and water pressure to prevent the pile from deforming or overturning.

[0003] Chinese patent provides a support structure for Larssen sheet piles, publication number CN214245684U, which includes two support columns for abutting against external Larssen sheet piles, wherein the end of the support column that abuts against the outer wall of the external Larssen sheet pile is the abutting end.

[0004] The construction workers of the above-mentioned support structure can adjust the distance between the contact plate and the support column according to the site conditions. When there is a gap between the contact plate and the Larssen steel sheet pile, the construction workers can rotate the second stud so that the outer peripheral wall of the second stud is threaded with the inner peripheral wall of the through groove. When the contact plate is attached to the Larssen steel sheet pile, the construction workers will pass one end of the limiting rod through one of the second limiting holes and then thread it with the first limiting hole. At this time, the second stud is restricted by the limiting rod and cannot rotate in the through groove.

[0005] However, its structure is relatively simple. The adjustment of the position of the support column and the contact plate is complicated by the use of multiple sets of bolts. At the same time, after the Larssen steel sheet pile is installed, multiple sets of support structures are required. Each set of support structures needs to be adjusted through this step, which is quite laborious. Furthermore, when supporting steel sheet piles, it is necessary to ensure that the height of each support rod is fixed. However, the lack of guide components means that measurements need to be taken every time during the installation process, which affects the support efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a support structure for Larssen sheet piles, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A support structure for Larssen sheet piles includes a support assembly disposed inside the bodies of two Larssen sheet piles. The support assembly has a support rod, a first abutment block, a guide plate, and a second abutment block. The first abutment block is fixedly installed on one side of the support rod, and an adjusting screw is threaded through the side of the support rod away from the first abutment block.

[0009] The adjusting screw is rotatably mounted with a connecting block on the side away from the support rod via a rotating block. Several extension rods are provided on the side of the connecting block away from the adjusting screw. The second abutment block is connected to the side of the last extension rod away from the adjusting screw. Guide plates are installed on the sides of the second abutment block and the first abutment block that are away from each other via fixing bolts. The sides of the two guide plates that are away from each other are in contact with the inner side of the Larssen sheet pile body.

[0010] Preferably, the two guide plates are supported by high manganese steel plates, and the sides of the guide plates that are far apart from each other are provided with anti-slip textures.

[0011] Preferably, a nut block is fixedly connected to the outer ring of the adjusting screw near the connecting block, and the adjusting screw and the support rod are detachably connected.

[0012] Preferably, the outer rings of the extension rod, the connecting block, and the second abutment block are each provided with a plurality of equidistant connecting ears near the connection point, and the front and rear ends of the connecting ears are threaded with connecting bolts, and the extension rod is detachably connected to the connecting block through the connecting bolts and the second abutment block.

[0013] Preferably, a positioning slot is provided on one side of the extension rod, and a locking block is fixedly connected to the other side of the extension rod, with the locking block engaging inside the positioning slot.

[0014] Preferably, there are several support components arranged at equal intervals inside the Larssen sheet pile body, and the several support components are at the same height.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by setting up a support component in conjunction with the Larssen sheet pile body, allows adjustment of the distance between the second abutment block and the first abutment block by turning the adjusting screw out of the support rod by tightening the nut block. This eliminates the need for frequent assembly, improves construction efficiency, and reduces the labor intensity of personnel. Furthermore, the extension rod, connecting lug, connecting block, and the second abutment block work together to adjust the initial distance between the second abutment block and the adjusting screw, providing high flexibility in use.

[0017] By setting up the first abutment block, the guide plate, the second abutment block, and the Larssen sheet pile body to cooperate with each other for support, the first abutment block and the second abutment block can be directly fixed at the guide plate. The guide plate plays a guiding role, and it is only necessary to restrict the guide plate to be in a straight line. It is not necessary to measure the relative position and installation height of each first abutment block during installation, which can improve assembly efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A support structure for Larssen sheet piles includes a support assembly 2 disposed inside two Larssen sheet pile bodies 1. The support assembly 2 has a support rod 3, a first abutment block 5, a guide plate 4, and a second abutment block 12. The first abutment block 5 is fixedly installed on one side of the support rod 3, and an adjusting screw 6 is threadedly connected through the support rod 3 on the side away from the first abutment block 5.

[0025] See Figure 2 and Figure 3 Furthermore, a connecting block 7 is rotatably installed on the side of the adjusting screw 6 away from the support rod 3 via a rotating block 8. Several extension rods 10 are provided on the side of the connecting block 7 away from the adjusting screw 6. The second contact block 12 is connected to the side of the last extension rod 10 away from the adjusting screw 6. Guide plates 4 are installed on the sides of the second contact block 12 and the first contact block 5 away from each other via fixing bolts. The sides of the two guide plates 4 away from each other are in contact with the inner side of the Larssen sheet pile body 1. The two guide plates 4 are supported by high manganese steel plates. Anti-slip textures are provided on the sides of the guide plates 4 away from each other. A nut block 9 is fixedly connected to the outer ring of the adjusting screw 6 near the connecting block 7. The adjusting screw 6 and the support rod 3 are detachably connected.

[0026] Specifically, after the Larssen sheet pile body 1 is installed, two guide plates 4 can be installed on the first and second contact blocks 12 using fixing bolts. Then, the support rod 3 can be placed inside the two Larssen sheet pile bodies 1. Subsequently, the nut block 9 can be turned with the help of existing tools such as a wrench, so that the adjusting screw 6 can be turned out from the inside of the support rod 3 to push the second contact block 12 away from the first contact block 5 until the two guide plates 4 are in contact with the inside of the Larssen sheet pile body 1. At this time, the support process is completed. Adjusting the distance between the two guide plates 4 in this way can reduce the tedious steps of assembly and adjustment, improve the support effect, and multiple first contact blocks 15 are installed on the guide plates 4. When supporting, it is only necessary to measure whether the height of both ends of the guide plates 4 is level, without having to measure the installation height of each first contact block 15 in turn, thus improving the installation efficiency. At the same time, multiple first contact blocks 15 are connected to each other through the guide plates 4 to improve their integrity and prevent the first contact block 15 from falling off directly if one part is accidentally loosened.

[0027] Example 2

[0028] See Figure 2 Furthermore, based on Embodiment 1, the extension rod 10, the connecting block 7, and the second abutment block 12 are all provided with several equidistantly arranged connecting ears 11 near the connection point on their outer rings. Connecting bolts 14 are threaded through the front and rear ends of the connecting ears 11. The extension rod 10 is detachably connected to the connecting block 7 through the connecting bolts 14 and the second abutment block 12. A positioning slot 13 is provided on one side of the extension rod 10, and a locking block is fixedly connected to the other side of the extension rod 10. The locking block is inserted into the positioning slot 13. Several support components 2 are provided. Several support components 2 are equidistantly arranged on the inner side of the Larssen sheet pile body 1, and several support components 2 are at the same height.

[0029] Specifically, when it is necessary to adjust the initial distance between the second contact block 12 and the first contact block 5, since the connecting block 7 is connected to the extension rod 10 through the connecting ear 11 and the connecting bolt 14, and the end of the extension rod 10 away from the connecting block 7 is connected to the second contact block 12, an appropriate number of extension rods 10 can be selected. Then, they can be spliced ​​end to end, and the insert block is made to be inserted into the positioning slot 13. Then, it is placed between the second contact block 12 and the connecting block 7, and they are connected to each other again through the connecting bolt 14. At this time, the combined length of the extension rods 10 is the extended length, which can change the distance between the second contact block 12 and the adjusting screw 6. When necessary, the support length can be adjusted by adding an appropriate number of extension rods 10. The flexibility of use is high. When the connecting bolt 14 is screwed in, high-strength anaerobic thread adhesive can be applied to the threads as needed to reduce the probability of it coming off.

[0030] In actual operation, after the Larssen sheet pile body 1 is installed, two guide plates 4 can be installed on the first contact block 5 and the second contact block 12 by fixing bolts. Then, the support rod 3 can be placed inside the two Larssen sheet pile bodies 1. Subsequently, the nut block 9 can be turned with the help of existing tools such as wrenches, so that the adjusting screw 6 can be turned out from the inside of the support rod 3 to push the second contact block 12 away from the first contact block 5 until the two guide plates 4 are in contact with the inside of the Larssen sheet pile body 1. At this time, the support process is completed. Adjusting the distance between the two guide plates 4 in this way can reduce the tedious steps of assembly and adjustment and improve the support effect.

[0031] Furthermore, multiple abutment blocks 5 are installed on the guide plate 4. When supporting, it is only necessary to measure whether the heights of the two ends of the guide plate 4 are level, without having to measure the installation height of each abutment block 5 in turn, thus improving installation efficiency. At the same time, multiple abutment blocks 5 are connected to each other through the guide plate 4 to improve their overall integrity and prevent abutment block 5 from falling off directly if one part becomes loose due to accident.

[0032] When it is necessary to adjust the initial distance between the second contact block 12 and the first contact block 5, since the connecting block 7 is connected to the extension rod 10 through the connecting ear 11 and the connecting bolt 14, and the end of the extension rod 10 away from the connecting block 7 is connected to the second contact block 12, an appropriate number of extension rods 10 can be selected. Then, they can be spliced ​​end to end, and the insert block is made to be inserted into the positioning slot 13. Then, it is placed between the second contact block 12 and the connecting block 7, and they are connected to each other again through the connecting bolt 14. At this time, the combined length of the extension rods 10 is the extended length, which can change the distance between the second contact block 12 and the adjusting screw 6. When necessary, the support length can be adjusted by adding an appropriate number of extension rods 10. The flexibility of use is high. When the connecting bolt 14 is screwed in, high-strength anaerobic thread adhesive can be applied to the threads as needed to reduce the probability of it coming off.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
