Technical Field

[0001] The utility model relates to the technical field of trench support, in particular to a module assembly trench support structure. Background Art

[0002] A trench is an open channel formed by artificial excavation. It can be used as a ditch, sewage pipe, or for laying pipes. Due to the large differences in soil quality in different geographical locations, as well as factors such as precipitation and water level in the trench, there may be a risk of trench collapse. To avoid collapse, it is generally necessary to install a support structure on the inner wall of the trench.

[0003] The existing utility model patent with announcement number CN212477760U discloses a pipeline groove support structure, including a plurality of support plates symmetrically arranged on the two side walls of the upper groove, a connecting plate connecting two adjacent support plates on the same side, and a first support frame for adjusting the distance between two opposite connecting plates, a telescopic plate for supporting the side wall of the lower groove is movably installed in the support plate, a sliding column sliding in two long grooves is provided at the end of the telescopic plate, an opening for the telescopic plate to rotate is provided at the bottom end of the side wall where the support plate and the upper groove are in contact, a second support frame for adjusting the distance between the two telescopic plates is installed between the two opposite telescopic plates, and the two ends of the second support frame are detachably hinged to the two telescopic plates.

[0004] The above-mentioned prior art solution has the following defects: the above-mentioned support structure needs to rotate the first threaded sleeve to make the two first support rods move away from each other, so as to tighten the connecting plate against the side wall of the groove. However, for some large grooves, the first threaded sleeve is located at a high position that is difficult for people to reach, which is not only difficult to operate but also difficult to twist, and the construction is relatively inconvenient. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a modular assembled trench support structure, which can complete the operation of pressing the support plate against the trench side wall on the slope without the need to operate at high places, and is convenient for construction.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a modular assembled groove support structure, including a support rod and support plates located at both ends of the support rod, the support plates are attached to the inner wall of the groove and installed at an angle, and multiple support plates are installed along the inner wall of the groove, and adjacent support plates are assembled and fixed by a connecting structure; a first latch tooth is fixed at both ends of the support rod, and a second latch tooth matching the first latch tooth is fixed on the side of the support plate facing the support rod, and both the first latch tooth and the second latch tooth are inverted teeth, the teeth of the first latch tooth are inclined upward, and the teeth of the second latch tooth are inclined downward.

[0007] Through the above technical solution, by setting the shapes of the first and second latch teeth, the first latch tooth can move downward to engage with the second latch tooth. Once the engagement is completed, the first latch tooth cannot move upward, and the one-way downward movement of the support rod is achieved through the inverted teeth. After the support plate is attached to the soil on the inner wall of the groove, the support rod is erected on the two oppositely arranged second latch teeth by lifting, so that the first latch tooth contacts the second latch tooth, and then the personnel hits the end of the support rod with a hammer, and the first latch tooth moves downward by a distance of one to two teeth through the knocking, so that the first latch tooth and the second latch tooth are tightly engaged, and can spontaneously limit the upward movement of the support rod to complete the installation. In this installation method, the personnel always stand on the ground, without the need to climb, which is safer and more operable, and there will be no situation where the support rod cannot be twisted.

[0008] Preferably, two levels are fixed on the support rod, and the two levels are respectively located near two ends of the support rod.

[0009] Through the above technical solution, a level ruler is used to facilitate personnel to observe the horizontality of the support rod, thereby avoiding the problem of the support rod being not horizontal after installation.

[0010] Preferably, a plurality of step plates are fixed on the support plate, and the step plates are located on both sides of the second latch tooth.

[0011] Through the above technical solution, the step plate is used for people to step on. Compared with the slope, on the one hand, it prevents people from slipping when entering and exiting the groove. On the other hand, the step plate is convenient for working on the end of the support rod, which is safer.

[0012] Preferably, the connection structure comprises an insert block fixed to one side of the support plate, and a slot is formed on the other side of the support plate away from the insert block, and the sizes of the insert block and the slot match each other.

[0013] Through the above technical solution, adjacent support plates are spliced ​​through plug-ins and slots, which achieves a preliminary positioning effect, thereby forming a support surface extending along the groove.

[0014] Preferably, the connection structure further comprises an inserting tube, and the inserting block and the inner wall of the slot are both provided with inserting holes for inserting the inserting tube, and the inserting tube limits the inserting block in the slot by being inserted into the inserting hole.

[0015] Through the above technical solution, the insert tube limits the insert block in the slot by inserting into the insert hole, limits the adjacent support plates, and avoids separation or misalignment between adjacent support plates.

[0016] Preferably, the cannula is a hose made of plastic.

[0017] Through the above technical solution, the intubation tube is a plastic hose, which can be purchased directly on the one hand, and is easy to transport and store on the other hand, and the installation process is also very convenient, with a single person placing the tube on the top of the support plate.

[0018] Preferably, the support rod is rotatably connected to a limit rod near both ends, the limit rod is hinged to the support rod through one end, the other end of the limit rod is in a drooping state under the action of gravity, and the lower end of the limit rod abuts against the outer side of the second latch tooth.

[0019] Through the above technical solution, when the limit rod droops naturally, the limit rod is located outside the first and second latch teeth at the same time, which can prevent the first latch tooth from sliding away from the second latch tooth in the front-back direction.

[0020] Preferably, a stopper is fixed to the outer wall of the support rod, and the limiting rod can abut against the stopper by rotating.

[0021] Through the above technical solution, when the limit rod abuts against the stop block, the stop block supports the limit rod. At this time, the limit rod does not block the second latch tooth, making it easy to remove the support rod from one side in the horizontal front and rear direction.

[0022] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0023] 1. The support rods and support plates are prefabricated in the factory and transported directly to the site for assembly. The modular installation method helps to improve construction efficiency;

[0024] 2. The personnel can complete the installation of the support rod by standing on the ground all the time, without climbing, which is safer and more operable, and there will be no situation where the support rod cannot be twisted;

[0025] 3. The disassembly and assembly of the support rods and support plates are relatively convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 , which is a modular assembled trench support structure disclosed by the utility model, includes a support rod 1, and support plates 2 located at both ends of the support rod 1. The support plates 2 are attached to the inner wall of the trench and installed at an angle. A plurality of support plates 2 are installed along the inner wall of the trench, and adjacent support plates 2 are assembled and fixed by a connecting structure. The support plates 2 play a role of compacting and supporting the soil on the inner wall of the trench, and make the trench present a flat and beautiful surface.

[0032] Reference Figure 1 and Figure 2 , the two ends of the support rod 1 are fixed with a latch tooth 11, and the side of the support plate 2 facing the support rod 1 is fixed with a latch tooth 2 3 that matches the latch tooth 11, and the latch tooth 2 3 extends downward along the inclined surface of the support plate 2, and the latch tooth 11 and the latch tooth 2 3 are both inverted teeth, and the teeth of the latch tooth 11 are inclined upward, and the teeth of the latch tooth 2 3 are inclined downward. By setting the shapes of the latch tooth 11 and the latch tooth 2 3, the latch tooth 11 can move downward and engage with the latch tooth 2 3. Once the engagement is completed, the latch tooth 11 cannot move upward, and the inverted teeth realize the unidirectional downward movement of the support rod 1, thereby limiting the support rod 1, thereby preventing the two opposing support plates 2 from approaching each other.

[0033] Two level rulers 12 are fixed on the support rod 1, and the two level rulers 12 are respectively located near the two ends of the support rod 1. Through the level ruler 12, it is convenient for personnel to observe the horizontality of the support rod 1, avoiding the problem that the support rod 1 is not horizontal after installation.

[0034] A plurality of step plates 4 are fixed on the support plate 2, and the step plates 4 are located on both sides of the second clamping teeth 3. A plurality of step plates 4 are installed downward along the inclined surface of the support plate 2. The step plates 4 are used for people to step on, which can prevent people from slipping when entering and exiting the groove, and it is safer to stand on the step plates 4 to operate the end of the support rod 1. The step plates 4 and the support plate 2 can be directly installed in the prefabrication factory, or they can be installed at the construction site of the groove later, and the installation method is welding or fixing by bolts.

[0035] The support rod 1 is rotatably connected to the position near both ends thereof, and the limit rod 13 is hinged to the support rod 1 through one end, and the other end of the limit rod 13 is in a drooping state under the action of gravity, and the lower end of the limit rod 13 abuts against the outer side of the second latching tooth 3. The limit rod 13 is arranged on both the front and rear side walls of the support rod 1, and when the limit rod 13 droops naturally, the limit rod 13 is simultaneously located on the outer side of the latching tooth 1 11 and the second latching tooth 3, which can prevent the latching tooth 1 11 from sliding away from the second latching tooth 3 in the front-back direction.

[0036] A stopper 14 is fixed to the outer wall of the support rod 1, and the limiting rod 13 can be rotated to abut against the stopper 14. When the limiting rod 13 abuts against the stopper 14, the stopper 14 supports the limiting rod 13, and the limiting rod 13 does not block the second latching tooth 3, so that the support rod 1 can be easily removed from one side in the horizontal front-back direction.

[0037] Reference Figure 1 and Figure 3 The connection structure includes an insert block 21 fixed to one side of the support plate 2, and a slot 22 is provided on the other side of the support plate 2 away from the insert block 21. The sizes of the insert block 21 and the slot 22 match each other. Adjacent support plates 2 are spliced ​​by the insert block 21 and the slot 22, thereby forming a support surface extending along the groove. The number of the insert block 21 and the slot 22 are both several.

[0038] The connection structure also includes a plug 23. The inner walls of the plug block 21 and the slot 22 are provided with a plug hole 24 for plugging the plug 23. The plug 23 is inserted into the plug hole 24 to limit the plug block 21 in the slot 22. The plug 23 is a plastic hose that can be purchased directly. A harder water pipe can be purchased directly for use. The plug 23 can be cut by a cutter. There are multiple plugs 23 plugged between the adjacent support plates 2 to improve the anti-separation effect. The plastic hose is also convenient for transportation and storage, and the installation process is also very convenient. A single person can place the pipe on the top of the support plate 2. If necessary, the water at the bottom of the groove can also be pumped out through the plug 23. Under normal circumstances, there is no force between the adjacent support plates to separate them from each other, so the use of the plug 23 for limiting is stable enough. When it needs to be removed, the plug 23 can be pulled out upwards, and the disassembly and assembly process is convenient and quick.

[0039] The implementation principle of the modular assembled trench support structure of this embodiment is as follows: the support rods 1 and the support plates 2 are prefabricated in the factory and directly transported to the site for assembly. This is a modular operation, which helps to improve construction efficiency.

[0040] After the support plate 2 is attached to the soil on the inner wall of the trench, insert the insert pipe 23 into the socket 24 to limit the adjacent support plates 2. Then, the support rod 1 is erected on the two oppositely arranged latch teeth 2 3 by hoisting, and the latch tooth 1 11 contacts the latch tooth 2 3. At this time, the latch tooth 1 11 is only placed on the latch tooth 2 3, and no latch connection is formed. Then, the personnel knocks the end of the support rod 1 with a hammer. When knocking, they can stand on the step plate 4, which is safer. At the same time, observe the level ruler 12 to avoid tilting of the support rod 1 after installation. By knocking, the latch tooth 1 11 moves downward by a distance of one to two teeth, so that the latch tooth 1 11 and the latch tooth 2 3 are tightly engaged, and can spontaneously limit the upward movement of the support rod 1.

[0041] It should be noted that the downward movement of the latch 11 under the knocking can be achieved by the elastic deformation of each structure, or by the slight outward movement of the support plate 2, so it can be implemented. In addition, the sizes of the latch 11 and the latch 2 3 in the drawings of this application are enlarged for the convenience of display, and are actually relatively small, so it can be implemented. If the knocking is slow to take effect, a heavy object can be placed on the support rod 1 to increase the efficiency.

[0042] When removal is required, the personnel rotate the limit rod 13 to the stopper 14, and then use a hammer to knock on the side wall of the support rod 1, gradually knocking out the end of the support rod 1 in the forward or backward direction, so that the first latch tooth 11 is disengaged from the second latch tooth 3.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
