Description

Technical Field

[0001] This invention belongs to the field of construction equipment technology, specifically a caisson internal frame support device and its usage method. Background Technology

[0002] A caisson is a cylindrical structure. It is formed by excavating soil into the well, relying on its own weight to overcome the frictional resistance of the well wall, and sinking it to the design elevation. Then, the bottom is sealed with concrete and the well hole is filled, making it the foundation of bridge piers or other structures.

[0003] However, in the existing technology, for caissons constructed by segmented prefabrication and segmented sinking using either drainage or non-drainage methods, the construction of the second and subsequent sections of the caisson structure faces challenges such as the lack of foundations for the inner supports or the deep foundations of the supports, making erection difficult. This hinders the rapid construction of the caisson. Furthermore, the existing internal supports of the caissons are structurally fixed, preventing them from being adjusted according to actual usage conditions, resulting in suboptimal equipment performance. Summary of the Invention

[0004] The purpose of this invention is to provide an internal frame support device for caissons and its usage method that allows for convenient adjustment of its own structure according to actual usage, thereby enabling the equipment to meet the needs of different specifications of caissons during use, and at the same time providing support for the internal structure of different specifications of caissons, so that the equipment can efficiently perform its intended functions.

[0005] The technical solution adopted in this invention is as follows: A caisson internal frame support device, comprising: a positioning mechanism, wherein two sets of positioning mechanisms are provided, each set of positioning mechanisms including a threaded rod and a connecting component, wherein threaded rod cups are threadedly connected to the outer surface of the threaded rod near both ends, and an extension rod is threadedly connected to the interior of one of the threaded rod cups, and the connecting component is disposed on the extension rod; and

[0006] A support mechanism is provided on a positioning mechanism. The support mechanism includes a base plate and a support component. A channel steel body is fixedly connected to the center of the top of the base plate. A slot is provided on the top of the base plate near one side edge. A locking strip is slidably inserted into the slot. The support component is provided on the base plate.

[0007] Each of the mounting threaded rods has a water-stop ring fitted on its outer surface near the center, each of the extension rods has an extension threaded hole at one end, and each of the extension rods has an external thread for connection near the other end edge on its outer surface.

[0008] Each of the extension rods has a locking hole at its top, and a locking bolt is slidably inserted into each locking hole.

[0009] Each of the connecting components includes a sleeve, which is slidably fitted onto the outer surface of the corresponding extension rod. A positioning ring is fixedly connected to one side of the outer surface of the sleeve, and an adjusting threaded rod is threadedly connected inside the positioning ring. A connecting block is slidably fitted onto the outer surface of the adjusting threaded rod.

[0010] Each of the adjusting threaded rods has multiple positioning external threads equidistantly opened on its outer surface, and multiple positioning holes equidistantly opened on its outer surface.

[0011] Each of the adjusting threaded rods has an adjusting threaded hole at one end, an adjusting external thread at the top edge of the outer surface of each adjusting threaded rod, a first anti-slip bolt slidingly penetrating the outer surface of each adjusting threaded rod near the top edge, and a limit nut threadedly connected to the outer surface of each first anti-slip bolt near both ends.

[0012] Each of the adjusting threaded rods has an adjusting ring threadedly connected to its outer surface via a positioning external thread, and a second anti-slip bolt is threadedly connected to one side of the outer surface of each adjusting ring. One end of each second anti-slip bolt extends into the corresponding positioning hole.

[0013] The base plate is fixedly connected to the interior of the two connecting blocks by bolts. Mounting frames are fixedly connected to the bottom of the base plate near both ends. A top strip is fixedly connected to the bottom of the base plate near one side edge. A groove is formed on the outer surface of one side of the top strip.

[0014] The supporting component includes two abutments. Each abutment has a first supporting threaded hole and a second supporting threaded hole on one side of its outer surface. Each second supporting threaded hole is threaded with a first abutment rod. Each first abutment rod has a splicing threaded hole at its top, and a second abutment rod is threaded with one of the splicing threaded holes.

[0015] A method for using an internal frame support device for a caisson includes the following steps:

[0016] S1. Prefabricated installation: During the actual pouring of the concrete structure, the threaded rods, waterstop rings and threaded rod cups can be pre-embedded in the designated locations. Then, during use, the threaded rod cups at different locations inside the concrete structure are selected according to the required support frame size to install the extension rods.

[0017] S2. Structural Assembly: Based on actual usage, a certain number of base plates are spliced ​​end to end. Multiple base plates are then fixed in position using sleeves, adjusting threaded rods, and connecting blocks. The first abutment rod inside the second support threaded hole is rotated to fit against the inner wall of the concrete structure, effectively supporting the bottom of the base plates. Additionally, depending on usage, new base plates can be fitted onto the top strip at the bottom of the fixed base plates via slots. The clips are then secured between the slots of the new base plates and the top strips of the fixed base plates via sliding grooves, enabling the parallel splicing of multiple base plates. The length of the first abutment rod can be adjusted via the first support threaded hole, providing bottom support between connected base plates and improving the overall stability of the spliced ​​base plates. Finally, the existing support frame is installed using the channel steel body.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In this invention, during actual concrete structure pouring, threaded rods, waterstop rings, and threaded rod cups are effectively pre-embedded in designated locations. Then, based on the required support frame size, threaded rod cups at different locations within the concrete structure are installed as extension rods. A certain number of base plates are then spliced ​​end-to-end according to actual usage. Multiple base plates are then fixed in position using sleeves, adjusting threaded rods, and connecting blocks. Finally, by rotating the first abutment inside the second support threaded hole, the first abutment effectively fits against the inner wall of the concrete structure, providing effective support to the bottom of the base plates. This can be adjusted according to actual usage. Furthermore, the newly added base plate is fitted onto the top strip at the bottom of the fixed base plate through a slot, and then the clip is secured between the slot of the newly added base plate and the top strip of the fixed base plate through a sliding groove. This effectively allows for the parallel splicing of multiple base plates. At the same time, the length of the first abutment can be adjusted through the first support threaded hole, thus effectively supporting the bottom of the connected base plates and improving the overall stability of the spliced ​​base plates. The channel steel body facilitates the installation of existing support frames, allowing the equipment to be easily adjusted according to actual usage conditions. This enables the equipment to stably provide internal support during the construction of concrete structures of different specifications. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] Example 1

[0032] Reference Figures 1-9A caisson internal frame support device includes a positioning mechanism 1 and a support mechanism 2. The positioning mechanism 1 comprises two sets, each including a threaded rod 101 and a connecting component. The threaded rod 101 provides a foundation for the installation of other functional components and ensures stable installation. Threaded rod cups 103 are threadedly connected to the outer surface of the threaded rod 101 near both ends. The threaded rod cups 103 effectively facilitate the splicing of extension rods 104. One threaded rod cup 103 has an extension rod 104 threadedly connected inside. The extension rod 104 facilitates the installation of other functional components. The connecting component is mounted on the extension rod 104. The support mechanism 2 is mounted on the positioning mechanism. In structure 1, the support mechanism 2 includes a base plate 201 and support components. A channel steel body 202 is fixedly connected to the center of the top of the base plate 201. The channel steel body 202 facilitates the installation and placement of existing support frames, enabling the equipment to efficiently perform its intended functions. A slot is provided near one edge of the top of the base plate 201. The slot, together with the top strip 204, facilitates the parallel splicing of multiple base plates 201, thereby allowing the equipment to easily adjust its own structure according to actual usage. A locking strip 203 is slidably inserted inside the slot. The locking strip 203, together with the slot, can effectively fix and restrict the position of the top strip 204, thereby enabling multiple base plates 201 to be spliced ​​side by side. The support components are set on the base plate 201.

[0033] Reference Figures 3-9Each threaded rod 101 has a water-stop ring 102 fitted near the center of its outer surface. The water-stop ring 102 effectively prevents water from penetrating the concrete structure body 3, thus ensuring that the concrete structure body 3 can perform its intended functions normally. Each extension rod 104 has an extension threaded hole at one end. The extension threaded hole, together with the connecting external thread, facilitates the splicing of multiple extension rods 104. Each extension rod 104 has a connecting external thread near the edge of its other end. The connecting external thread allows multiple extension rods 104 to be spliced ​​securely. Each extension rod 104 has a locking hole at its top. The locking hole facilitates the installation of the locking bolt 105. A locking bolt 105 is slidably inserted into each locking hole. 5. The clamp 105 effectively restricts the position of the sleeve 106, facilitating its installation and removal, and enabling the equipment to perform its intended functions efficiently. Each set of connecting components includes a sleeve 106. The sleeve 106 facilitates the installation of other functional components and provides support for the extension rod 104. The sleeve 106 slides on the outer surface of the corresponding extension rod 104. A positioning ring 107 is fixedly connected to one side of the outer surface of the sleeve 106.

The adjusting threaded rod 108 facilitates the installation of other functional components. A connecting block 112 is slidably fitted onto the outer surface of rod 108. The connecting block 112 facilitates the installation of the base plate 201 and allows for easy adjustment of the connection angle of the base plate 201. Multiple positioning external threads are equidistantly provided on the outer surface of each adjusting threaded rod 108, facilitating the adjustment of the installation position of the adjusting ring 110. Multiple positioning holes are equidistantly provided on the outer surface of each adjusting threaded rod 108, facilitating the installation of the second anti-slip bolt 111. An adjusting threaded hole is provided at one end of each adjusting threaded rod 108, allowing for easy splicing of multiple adjusting threaded rods 108 in conjunction with the adjusting external threads. Adjusting external threads are also provided on the outer surface of each adjusting threaded rod 108 near the top edge. Each adjusting threaded rod 108 has a first anti-slip bolt 109 slidingly inserted near its top edge on its outer surface. The first anti-slip bolt 109 effectively prevents the adjusting threaded rod 108 from accidentally disengaging from the positioning ring 107. Each first anti-slip bolt 109 has a limit nut threadedly connected near both ends on its outer surface. The limit nut effectively fixes and restricts the position of the first anti-slip bolt 109. Each adjusting threaded rod 108 has an adjusting ring 110 threadedly connected to its outer surface via a positioning external thread. The adjusting ring 110 facilitates the installation and adjustment of the base plate 201's height. Each adjusting ring 110 has a second anti-slip bolt 111 threadedly connected to one side of its outer surface. The second anti-slip bolt 111 effectively fixes the position of the adjusting ring 110.To prevent the adjusting ring 110 from accidentally detaching, one end of each second anti-slip bolt 111 extends into the corresponding positioning hole. The base plate 201 is fixedly connected to the interior of the two connecting blocks 112 by bolts. Mounting frames 205 are fixedly connected to the bottom of the base plate 201 near both ends. The mounting frames 205 facilitate the installation and removal of the abutment blocks 206. A top strip 204 is fixedly connected to the bottom of the base plate 201 near one side edge. The top strip 204, in conjunction with the slot, allows for the effective parallel splicing of multiple base plates 201. A sliding groove is provided on one outer surface of the top strip 204. The sliding groove effectively allows for the installation of the locking strip 203, thereby effectively restricting the position of the top strip 204. The support components include two... Each abutment block 206 facilitates the installation of other functional components of the equipment. Each abutment block 206 has a first support threaded hole and a second support threaded hole on one outer surface. The first support threaded hole, in conjunction with the second support threaded hole, facilitates the installation of a first abutment rod 207. Each second support threaded hole contains a threaded connection to a first abutment rod 207. The first abutment rod 207, together with the abutment block 206, effectively provides stable support to the bottom of the base plate 201. Each first abutment rod 207 has a splicing threaded hole at its top, facilitating the installation of a second abutment rod 208. One of the splicing threaded holes contains a threaded connection to a second abutment rod 208, which effectively extends and adjusts the working length of the first abutment rod 207.

[0034] The following provides a detailed description of the method of using an internal frame support device for caissons provided in an embodiment of the present invention. The method of use includes the following steps:

[0035] Step 1: Prefabrication Installation: During the actual pouring of the concrete structure body 3, the threaded rod 101, waterstop ring 102 and threaded rod cup 103 can be effectively pre-embedded in the designated usage position. Then, during use, according to the required support frame size, the threaded rod cup 103 at different positions inside the concrete structure body 3 is selected to install the extension rod 104.

[0036] Step 2, Structural Assembly: Based on actual usage, a certain number of base plates 201 are spliced ​​end-to-end. Then, multiple base plates 201 are fixed in position using sleeves 106, adjusting threaded rods 108, and connecting blocks 112. Next, by rotating the first abutment 207 inside the second support threaded hole, the first abutment 207 can effectively fit against the inner wall of the concrete structure body 3, providing effective support for the bottom of the base plates 201. Simultaneously, depending on actual usage, newly added base plates 201 can be fitted onto the top strip 204 at the bottom of the fixed base plates 201 through slots. Then, the locking strip 203 is secured to the newly added base plates through sliding grooves. The slot of the base plate 201 and the top strip 204 of the fixed base plate 201 can effectively complete the parallel splicing of multiple base plates 201. At the same time, the length of the first abutment 207 can be adjusted through the first support threaded hole, thereby effectively supporting the bottom between the connected base plates 201, thus improving the overall stability of the support of the spliced ​​base plates 201. Furthermore, the existing support frame can be easily installed through the channel steel body 202, allowing the equipment to conveniently adjust its own structure according to the actual use situation, and enabling the equipment to stably provide internal support during the construction of concrete structure bodies 3 of different specifications.
