Description

Technical Field

[0001] This utility model relates to the technical field of column template connection mechanism, specifically a connection structure for splicing column templates. Background Technology

[0002] Steel column formwork is a type of steel template specifically designed for manufacturing concrete columns. It typically consists of multiple perpendicular longitudinal and transverse stiffening plates, sometimes with reinforcing angle steel welded to the transverse stiffening plates and bolt holes for easy connection and fixation. The design of steel column formwork allows it to maintain precise geometry and dimensions during concrete pouring, while also withstanding the weight of the concrete and lateral pressures generated during construction. The use of steel column formwork improves construction efficiency, reduces on-site work, and, due to its durability, can be reused multiple times. Steel column formwork is widely used in infrastructure construction such as roads, bridges, railways, and buildings. It can be used to create columns for structures such as traffic dividers, street light bases, and bridge piers. In modern engineering construction, steel column formwork is favored due to its durability and high reusability.

[0003] A search revealed Chinese patent application CN202023221261.6, which discloses a column steel formwork, comprising a first steel formwork outer plate and a second steel formwork outer plate. A fixing block is provided on the back of the first steel formwork outer plate, and the back of the first steel formwork outer plate is fixedly connected to the front of the fixing block. A screw is provided in the middle of the fixing block. The two first steel formwork outer plates are bolted together with the fixing block and the screw. Multiple rotating ears are provided on the front of the first steel formwork outer plate, and a rotating shaft is inserted through the middle of each rotating ear. The front of the first steel formwork outer plate is rotatably connected to one side of the second steel formwork outer plate through the rotating ears and the rotating shaft. This utility model facilitates the disassembly and assembly of the steel formwork outer plates by rotatably connecting the two first steel formwork outer plates through rotating ears and a rotating shaft, and fixing them together with bolts. It allows for various shapes to be assembled according to the required building column shape, and facilitates transportation and storage after disassembly.

[0004] When using column steel formwork, after assembly, concrete is poured into the formwork cavity. When splicing adjacent formwork, fixing screws are inserted into the reserved holes for locking. However, in long-term use, relying solely on fixing screws cannot guarantee the stability and safety of column steel formwork. Therefore, additional connection structures are needed to strengthen the connection strength of column steel formwork. To solve the above problems, we need to propose a connection structure for splicing column formwork. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1-4 , the present utility model provides a technical solution: A connecting structure for splicing column templates, comprising: A set of threaded rods 1 and several sets of connecting seats 2; the connecting seats 2 are arranged in a U-shape, bumps 3 are provided on the outer walls of the connecting seats 2, through holes 4 are opened on the bumps 3, and the threaded rods 1 are slidably inserted into the through holes 4; A locking mechanism is provided on the connecting seat 2; the locking mechanism includes a locking screw hole 5 and a locking screw 6 opened on one side wall of the connecting seat 2. The locking screw 6 is threaded inside the locking screw hole 5. One end of the locking screw 6 is provided with a clamping block 7, and the other end of the locking screw 6 is welded with a handle 9; anti-slip strips 8 are provided on the side wall of the clamping block 7, and multiple sets of anti-slip strips 8 are distributed in a equidistant ring.

[0017] By setting a threaded rod 1 and a connecting seat 2 with a protrusion 3, the connecting seat 2 is slidably installed on the threaded rod 1 through the protrusion 3 with a through hole 4 and locked in position by the upper positioning ring 10 and the lower positioning ring 11. The connecting seat 2 is provided with a locking mechanism including a locking screw hole 5 and a locking screw 6. One end of the locking screw 6 is provided with a clamping block 7 and the other end is provided with a handle 9. In use, the threaded rod 1 is placed on one side of the column template, and the connecting seat 2 is clamped on the outside of the side of the adjacent template. Rotating the handle 9 causes the clamping block 7 to clamp and lock the two sets of sides. Combined with the original screw fixing of the template, it has an additional connection locking structure, which greatly enhances the tightness of the column template splicing. In summary, this device has a simple structure and is easy to use. Through the connecting seat 2 and the locking mechanism, it can firmly lock the sides of adjacent steel molds, which improves the tightness of the connection between adjacent steel molds, making the column formwork have high stability and safety, and has high practical value.

[0018] For further details, please refer to Figure 1 and Figure 4 : It also includes a positioning mechanism for positioning the connecting seat 2, which includes an upper positioning ring 10 and a lower positioning ring 11. Both the upper positioning ring 10 and the lower positioning ring 11 are threaded onto the threaded rod 1, and both the upper positioning ring 10 and the lower positioning ring 11 are provided with washers 12, which are integrally molded from rubber.
