Description

A type of precast inclined brace with post-grouting at the pile end Technical Field

[0001] This utility model relates to the technical field of pile end construction support equipment, and in particular to a precast inclined brace for post-grouting at the pile end. Background Technology

[0002] In foundation pit engineering, slab support is generally used in combination with tie anchors or internal bracing. Tie anchors often extend beyond the boundary line, causing significant environmental impact and thus being subject to restrictions; while internal bracing is not only expensive but can also hinder the smooth construction of the main building, affecting the development schedule. To address these issues, engineers have developed a front-supported support system, which effectively solves the problems of environmental impact and main building construction, and its application in engineering is becoming increasingly widespread.

[0003] In practical applications, the use of prefabricated diagonal braces in existing technologies still presents the following two problems:

[0004] 1. The diagonal bracing equipment has the problem of limited functionality and poor support stability, creating on-site safety hazards;

[0005] 2. The equipment can only be operated with a single diagonal brace, resulting in low overall flexibility and affecting normal use.

[0006] Therefore, this application provides a precast inclined brace with post-grouting at the pile end. Summary of the Invention

[0007] The purpose of this application is to address the shortcomings of the existing technology and provide a precast inclined brace with post-grouting at the pile end.

[0008] To achieve the above objectives, this application adopts the following technical solution: a precast inclined brace for post-grouting at the pile end, comprising two precast support plates.

[0009] A connecting plate is installed between the two prefabricated support plates, and each of the two prefabricated support plates has an installation groove inside for use with the connecting plate;

[0010] One of the prefabricated support plates is equipped with a first diagonal bracing mechanism on its top;

[0011] Another precast support plate has a second diagonal bracing mechanism installed on its top. The second diagonal bracing mechanism includes an installation rod. The installation rod is fixedly connected to the top of the other precast support plate. A support column is fixedly connected to the top of the installation rod. Two limiting sleeves are fitted on the outside of the support column. A first rotating plate and a second rotating plate are rotatably connected to the outside of the support column and the side away from the limiting sleeves. The second rotating plate is located below the first rotating plate. A diagonal bracing support sleeve is fitted on the side of the first rotating plate and the side away from the second rotating plate. A second limiting pivot is installed on the top of each of the two diagonal bracing support sleeves. One of the second limiting pivots passes through the second rotating plate and is connected to the diagonal bracing support sleeve. The other second limiting pivot passes through the first rotating plate and is connected to the diagonal bracing support sleeve.

[0012] In a preferred embodiment, the first diagonal bracing mechanism includes an auxiliary support plate, wherein an auxiliary support plate is mounted on the top of one of the prefabricated support plates, an adjusting plate is rotatably connected to one side of the auxiliary support plate, an electric telescopic rod is rotatably connected inside the auxiliary support plate, the output end of the electric telescopic rod is rotatably connected to the adjusting plate, a diagonal bracing support plate is mounted on the side of the adjusting plate away from the auxiliary support plate, second bolt holes are evenly distributed inside the diagonal bracing support plate, a sixth positioning bolt is installed inside the second bolt holes, and a first positioning bolt extending into the interior of the adjusting plate is mounted on the outer side of the diagonal bracing support plate.

[0013] The technical advantages of adopting the above-mentioned further solution are as follows: the first positioning bolt limits the installation of the diagonal brace support plate and the adjusting plate, which facilitates normal maintenance during disassembly. The diagonal brace operation is performed by adjusting the adjusting plate and the diagonal brace support plate during use. The electric telescopic rod is operated to drive the adjustment plate support angle to be adjusted until the required angle is reached, which improves the flexibility of the equipment during use and meets different operating scenarios.

[0014] In a preferred embodiment, second positioning bolts extending into the support column are installed on both sides of the first rotating plate, and second positioning bolts extending into the support column are installed on both sides of the second rotating plate. The second positioning bolts limit the rotation of the first rotating plate after adjustment. Third positioning bolts extending into the support column are installed on both sides of the second rotating plate. The third positioning bolts limit the rotation of the second rotating plate after adjustment, thereby providing normal protection for the first and second rotating plates after angle adjustment and extending the service life of the equipment. Fourth positioning bolts extending into the support column are installed on the outer sides of both limiting sleeves.

[0015] The technical effect of adopting the above-mentioned further solution is that the limiting sleeve and the support column are reinforced and installed by means of the fourth positioning bolt.

[0016] In a preferred embodiment, a first limiting pivot is installed at the connection between the auxiliary support plate and the adjusting pivot, and the first limiting pivot passes through both ends of the auxiliary support plate and is fitted with locking rods.

[0017] The technical effect of adopting the above-mentioned further solution is that the first limit pivot, in conjunction with the auxiliary support plate and the adjusting pivot, rotates normally. The locking rod locks the auxiliary support plate and the first limit pivot after the adjustment is completed, preventing the adjusting pivot from resetting, thereby ensuring the secondary diagonal bracing operation.

[0018] In a preferred embodiment, each of the two precast support plates is fixedly connected to a mounting side plate on the side away from the first diagonal bracing mechanism. Each mounting side plate has four first bolt holes, and a fifth positioning bolt is installed inside each of the four first bolt holes. The fifth positioning bolt, in conjunction with the mounting side plate, facilitates the reinforcement installation of the precast support plate to one side of the wall during construction, thereby improving the stability of the equipment during use. The connecting plate has two first mounting holes inside, which are symmetrically distributed. Reinforcing bars are installed inside the two first mounting holes.

[0019] The technical effect of adopting the above-mentioned further solution is that reinforcing steel bars are inserted through the first mounting hole to support the overall equipment.

[0020] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0021] By setting up a prefabricated support plate, a first diagonal brace mechanism, a second diagonal brace mechanism, and a fourth positioning bolt, the first positioning bolt limits the installation of the diagonal brace support plate and the adjusting rotating plate during use, facilitating normal maintenance during disassembly. The adjusting rotating plate and diagonal brace support plate are used for diagonal bracing operations. The electric telescopic rod rotates, driving the adjusting rotating plate to adjust its support angle to the desired angle, improving the flexibility of the equipment and meeting different operating scenarios. The third positioning bolt limits the second rotating plate on both sides after rotation adjustment, thus protecting the first and second rotating plates after angle adjustment and extending the equipment's service life. The fourth positioning bolt reinforces the installation of the limiting sleeve and support column. A fifth positioning bolt is installed inside each of the four first bolt holes. This fifth positioning bolt, in conjunction with the side plate installation, facilitates the reinforcement installation of the prefabricated support plate to one side of the wall during construction, improving the stability of the equipment during use. Two first mounting holes are symmetrically distributed, and reinforcing bars are installed inside both first mounting holes. Reinforcing steel bars are inserted through the first mounting hole to support the entire equipment. Two prefabricated support plates are reinforced by the cooperation of two mounting side plates and the first bolt hole. The two prefabricated support plates are then reinforced and connected by a connecting plate. In actual operation, the first diagonal bracing mechanism performs a first diagonal bracing operation on site, and the second diagonal bracing mechanism performs a second diagonal bracing operation on site. The entire equipment does not use electricity during operation, saving overall usage and installation costs. At the same time, it improves the stability of the diagonal bracing support, is applicable to different working environments, improves the flexibility of equipment use, and solves the technical problems of single function and poor support stability of existing diagonal bracing equipment.

[0031] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] As shown in Figures 1-4, this embodiment provides a technical solution: a precast inclined brace for post-grouting at the pile end, comprising two precast support plates 1, a connecting plate 11 installed between the two precast support plates 1, and mounting grooves 12 for use with the connecting plate 11 in the interior of each of the two precast support plates 1; a first inclined brace mechanism 2 is installed on the top of one precast support plate 1; a second inclined brace mechanism 3 is installed on the top of the other precast support plate 1, the second inclined brace mechanism 3 including a mounting rod 31, the mounting rod 31 is fixedly connected to the top of the other precast support plate 1, a support column 32 is fixedly connected to the top of the mounting rod 31, two limiting sleeves 33 are sleeved on the outside of the support column 32, a first rotating plate 34 and a second rotating plate 35 are rotatably connected to the outside of the support column 32 and away from the limiting sleeves 33, the second rotating plate 35 is located below the first rotating plate 34, and the first rotating plate 34 and the second rotating plate 35 are far apart. One side is fitted with a diagonal brace support sleeve 36. The top of each of the two diagonal brace support sleeves 36 is equipped with a second limiting shaft 37. One of the second limiting shafts 37 passes through the second rotating plate 35 and is connected to the diagonal brace support sleeve 36. The other second limiting shaft 37 passes through the first rotating plate 34 and is connected to the diagonal brace support sleeve 36. The two prefabricated support plates 1 are reinforced by the cooperation of the two mounting side plates 14 and the first bolt holes 15. The two prefabricated support plates 1 are reinforced and connected by the connecting plate 11. In actual operation, the first diagonal brace mechanism 2 is used for the first diagonal brace operation on site, and the second diagonal brace mechanism 3 is used for the second diagonal brace operation on site. The whole equipment does not use electricity during operation, saving the overall use and installation costs. At the same time, it improves the stability of the diagonal brace support, is applicable to different working environments, improves the flexibility of the equipment, and solves the technical problems of single function and poor support stability of the existing diagonal brace equipment.

[0033] Furthermore, as shown in Figures 1-4: the first diagonal bracing mechanism 2 includes an auxiliary support plate 21, on the top of a prefabricated support plate 1. An adjusting plate 24 is rotatably connected to one side of the auxiliary support plate 21. An electric telescopic rod 22 is rotatably connected inside the auxiliary support plate 21, and its output end is rotatably connected to the adjusting plate 24. A diagonal bracing support plate 25 is installed on the side of the adjusting plate 24 away from the auxiliary support plate 21. The diagonal bracing support plate 25 has equidistantly distributed second bolt holes 26 inside, and sixth positioning bolts are installed inside the second bolt holes 26. A first positioning bolt 27 extending into the adjusting plate 24 is installed on the outer side of the diagonal bracing support plate 25. The first positioning bolt 27 is used to secure the diagonal bracing support plate 25 and the adjusting plate 24. The installation with limit switches facilitates normal maintenance during disassembly. The first diagonal bracing operation is performed by adjusting the rotating plate 24 and the diagonal support plate 25. The electric telescopic rod 22 rotates, driving the rotating plate 24 to adjust its support angle until the desired angle is reached, improving the equipment's flexibility and meeting different operating scenarios. A first limit rotating shaft 23 is installed at the connection between the auxiliary support plate 21 and the adjusting rotating plate 24. The first limit rotating shaft 23 passes through both ends of the auxiliary support plate 21, and locking rods are fitted on its outer sides. The first limit rotating shaft 23, in conjunction with the auxiliary support plate 21 and the adjusting rotating plate 24, allows for normal rotation. The locking rods then lock the auxiliary support plate 21 and the first limit rotating shaft 23 after adjustment, preventing the adjusting rotating plate 24 from resetting and ensuring the second diagonal bracing operation can proceed.

[0034] The above solution still has the problem of not positioning the angle-adjusting brace, as shown in Figures 1-4. In this solution, the first rotating plate 34 is equipped with second positioning bolts 38 extending into the support column 32 on both sides. The second rotating plate 35 is also equipped with second positioning bolts 38 extending into the support column 32 on both sides. The second positioning bolts 38 limit the first rotating plate 34 on both sides after the rotation adjustment is completed. The second rotating plate 35 is equipped with third positioning bolts 39 extending into the support column 32 on both sides. The third positioning bolts 39 limit the second rotating plate 35 on both sides after the rotation adjustment is completed. This provides normal protection for the first rotating plate 34 and the second rotating plate 35 after the angle adjustment is completed, extending the service life of the equipment. The outer sides of the two limiting sleeves 33 are equipped with fourth positioning bolts 4 extending into the support column 32. The fourth positioning bolts 4 reinforce the installation of the limiting sleeves 33 and the support column 32.

[0035] The above solutions also have the problem of poor overall equipment support stability. As shown in Figures 1 and 2, in this solution, the two prefabricated support plates 1 are fixedly connected to the side away from the first diagonal bracing mechanism 2 with mounting side plates 14. The mounting side plates 14 are provided with four first bolt holes 15, and the four first bolt holes 15 are installed with fifth positioning bolts. The fifth positioning bolts, in conjunction with the mounting side plates 14, facilitate the reinforcement and installation of the prefabricated support plates 1 and one side wall during construction, thereby improving the stability of the equipment during use.

[0036] The above solutions also have the problem of not providing auxiliary support for the overall equipment. As shown in Figures 1 and 2, in this solution, the connecting plate 11 has two first mounting holes 13 inside. The two first mounting holes 13 are symmetrically distributed, and reinforcing bars are installed inside the two first mounting holes 13. The reinforcing bars are inserted through the first mounting holes 13 to support the overall equipment.

[0037] Working principle:

[0038] As shown in Figure 1-4:

[0039] When in use, the first positioning bolt 27 is used to limit the installation of the diagonal brace support plate 25 and the adjusting plate 24, which facilitates normal maintenance during disassembly. The diagonal brace operation is performed once during use by adjusting the adjusting plate 24 and the diagonal brace support plate 25.

[0040] The electric telescopic rod 22 operates, which drives the adjustment plate 24 to adjust the support angle until the required angle is reached, thus improving the flexibility of the equipment during use and meeting the needs of different operating scenarios.

[0041] The first limiting pivot 23 passes through both ends of the auxiliary support plate 21 and is fitted with locking rods on both sides. The first limiting pivot 23, together with the auxiliary support plate 21 and the adjusting pivot 24, rotates normally. The locking rods lock the auxiliary support plate 21 and the first limiting pivot 23 after adjustment to prevent the adjusting pivot 24 from resetting, thereby ensuring the secondary diagonal bracing operation.

[0042] The first rotating plate 34 is limited on both sides by the second positioning bolt 38 after the rotation adjustment is completed, and the second rotating plate 35 is limited on both sides by the third positioning bolt 39 after the rotation adjustment is completed. This provides normal protection for the first rotating plate 34 and the second rotating plate 35 after the angle adjustment is completed, and extends the service life of the equipment.

[0043] The limiting sleeve 33 and the support column 32 are reinforced and installed by the fourth positioning bolt 4. The fifth positioning bolt is installed inside each of the four first bolt holes 15. The side plate 14 is installed by the fifth positioning bolt to facilitate the reinforcement and installation of the prefabricated support plate 1 and one side wall during construction, which improves the stability of the equipment during use.

[0044] Two first mounting holes 13 are symmetrically distributed, and reinforcing bars are installed inside the two first mounting holes 13. The reinforcing bars are inserted through the first mounting holes 13 to support the overall equipment.

[0045] The two prefabricated support plates 1 are reinforced by the cooperation of two mounting side plates 14 and the first bolt hole 15. The two prefabricated support plates 1 are reinforced and connected by the connecting plate 11. In actual operation, the first diagonal bracing mechanism 2 performs the first diagonal bracing operation on site, and the second diagonal bracing mechanism 3 performs the second diagonal bracing operation on site. The whole equipment does not use electricity during operation, saving the overall use and installation costs. At the same time, it improves the stability of the diagonal bracing support, is applicable to different working environments, improves the flexibility of equipment use, and solves the technical problems of single function and poor support stability of existing diagonal bracing equipment.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any other way. Any person skilled in the art may use the above-disclosed technical content to make changes or modifications to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this application without departing from the technical solution of this application shall still fall within the protection scope of this application.
