Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically a combined pier steel formwork. Background Technology

[0002] Existing modular pier steel formwork uses bolts and nuts to fasten the pier during assembly. Therefore, when constructing a large pier, a large number of formworks are often required for assembly, which requires a large number of bolts and nuts. This makes the fixing process cumbersome, time-consuming, and labor-intensive. Furthermore, each set of bolts and nuts must be removed sequentially during disassembly, which is time-consuming, labor-intensive, and affects construction efficiency.

[0003] Publication No. CN222878544U discloses a combined pier steel formwork, including a first formwork and a second formwork. The second formwork is detachably installed on one side of the first formwork, and the first and second formworks are installed symmetrically. Both the first and second formworks have an integrally formed annular mounting block at their tops, and annular mounting grooves are formed at their bottoms. A plug is fixedly welded to the outer wall of one side of each formwork, with an integrally formed insertion block at the front end. A socket is fixedly welded to the outer wall of the other side of each formwork. The two sets of formwork can be assembled and secured using only bolts. When stacking the formwork components, they only need to be screwed into the annular mounting grooves via the annular mounting blocks, eliminating the need for other fasteners. The installation is convenient, time-saving, and labor-saving. Disassembly is also quick, as the bolts can be removed to separate the formwork, improving construction efficiency. However, this patent still has the following problems in practical use:

[0004] The aforementioned device still requires the use of three bolts on one side and six bolts on both sides for fastening. Compared to the existing steel templates, the number of bolts reduced is only limited. Furthermore, when reinforcing two spliced ​​templates, each bolt needs to be rotated individually, and the large number of bolts greatly increases the operational burden.

[0005] A combined pier steel formwork is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a combined pier steel formwork to solve the problem that the above-mentioned device still requires the use of three bolts on one side and six bolts on both sides for fastening. Compared with the existing steel formwork, the number of bolts is reduced only slightly. Furthermore, when reinforcing two spliced ​​formworks, it is necessary to rotate each bolt one by one, and the large number of bolts greatly increases the operational burden.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a combined pier steel formwork, comprising a first formwork and a second formwork;

[0008] A connecting component is provided at the joint between the first template and the second template. The connecting component includes a butt plate and several bending blocks. A clearance hole is provided in the middle of the bending block. A synchronization hole is provided vertically in the middle of the butt plate. Several vertically distributed insertion holes are also provided on the butt plate.

[0009] The connecting component includes a bent plate with limit holes at both ends and a threaded sleeve fixedly embedded in the middle of the bent plate, the threaded sleeve being threadedly connected to a threaded post.

[0010] The synchronization hole is connected to a pull tube, and a hand-held plate is fixedly connected to the top end of the pull tube.

[0011] Preferably, the bending block is inserted into the socket, and the synchronization hole is connected to the socket.

[0012] Preferably, the pull tube passes through the insertion hole.

[0013] Preferably, the pulling tube also extends through the limiting hole.

[0014] Preferably, one end of the threaded post is rotatably connected to a compression pad; the other end of the threaded post is fixedly connected to a nut.

[0015] Preferably, the compression pad is attached to the outer side of the mating plate.

[0016] Preferably, the bending block is fixedly connected to the second template, and the mating plate is fixedly connected to the first template.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This combined pier steel formwork, through ingenious structural cooperation, only requires rotating two threaded columns to achieve multiple points of tension and fastening, avoiding the use of too many bolts, making assembly more convenient and efficient, and significantly enhancing the tightness of the steel formwork joints and the stability of the connection assembly. The specific details are as follows:

[0018] 1. By setting up a connecting plate and bending blocks, the bending blocks are inserted into the insertion holes of the connecting plate to achieve initial positioning, providing a foundation for subsequent connection operations. The cooperation between the bending plate and the pull tube allows the pull tube to move within multiple holes and generate tensile force through a series of mechanical transmissions when the threaded column is rotated, achieving fastening at multiple points. This design avoids the use of excessive bolts, reduces the number of parts and operation steps required during assembly, and greatly improves assembly efficiency. At the same time, the micro-movement of the pull tube within the synchronization hole and the pulling of the bending block through the avoidance hole effectively increase the tightness of the joint between the first and second templates, improve the stability of the entire steel formwork connection assembly, and ensure that the steel formwork can withstand various external forces during construction, guaranteeing construction quality and safety.

[0024] 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.

[0025] Please see Figures 1-4 The present invention provides a technical solution: a combined pier steel formwork, comprising a first formwork 1 and a second formwork 2;

[0026] A connecting component 3 is provided at the joint of the first template 1 and the second template 2. The connecting component 3 includes a mating plate 303 and several bending blocks 301. A clearance hole 302 is provided in the middle of the bending block 301. A synchronization hole 304 is vertically provided in the middle of the mating plate 303. Several vertically distributed insertion holes 305 are also provided on the mating plate 303. When the first template 1 and the second template 2 are assembled, the bending block 301 is inserted into the mating plate 303 through the insertion hole 305. At this time, the synchronization hole 304 is aligned with the clearance hole 302. Then, the bending plate 306 is held so that the limiting hole 307 is aligned with the synchronization hole 304. Then, the pulling tube 311 is passed through the limiting hole 307, the synchronization hole 304 and the clearance hole 302, so that the mating plate 303, the pulling tube 311 and the bending block 301 are interlocked.

[0027] The connecting component 3 includes a bending plate 306, with limiting holes 307 at both ends of the bending plate 306. A threaded sleeve 308 is fixedly embedded in the middle of the bending plate 306, and a threaded post 309 is threadedly connected to the threaded sleeve 308. The threaded post 309 is then rotated, causing it to push the extrusion pad 310 to move and fit tightly against the clearance hole 302. The subsequent reaction force causes the bending plate 306 to drive the pulling tube 311 to move further within the synchronization hole 304.

[0028] The synchronous hole 304 is connected to a pulling tube 311, and the top end of the pulling tube 311 is fixedly connected to a hand-held plate 312. The synchronous hole 304 is elliptical. When the pulling tube 311 pulls the bending block 301 through the clearance hole 302, the first template 1 and the second template 2 are further pressed together, increasing the stability of the joint between the first template 1 and the second template 2.

[0029] The bending block 301 is inserted into the socket 305, and the synchronization hole 304 is connected to the socket 305.

[0030] The pull tube 311 passes through the insertion hole 305; the pull tube 311 also passes through the limiting hole 307; the pull tube 311 will move within the avoidance hole 302 and the synchronization hole 304.

[0031] One end of the threaded column 309 is rotatably connected to the compression pad 310; the other end of the threaded column 309 is fixedly connected to the nut; after the compression pad 310 fits into the clearance hole 302, continuing to rotate the threaded column 309 will cause the bending plate 306 to pull the pulling tube 311 slightly, increasing the stability of the connection between the first template 1 and the second template 2.

[0032] The compression pad 310 is attached to the outer side of the mating plate 303.

[0033] The bending block 301 is fixedly connected to the second template 2, and the mating plate 303 is fixedly connected to the first template 1. This device only requires rotating two threaded columns 309 to allow the pulling tube 311 to be pulled and tightened at multiple points, and it can avoid using too many bolts, making operation more convenient and increasing the stability during connection and assembly.

[0034] Working principle: Before using this type of combined pier steel formwork, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 4 As shown, the first template 1 and the second template 2 are first assembled. At this time, since the bending block 301 is fixedly connected to the second template 2 and the mating plate 303 is fixedly connected to the first template 1, the bending block 301 is inserted into the mating plate 303 through the insertion hole 305, so that the synchronization hole 304 is aligned with the clearance hole 302.

[0035] Next, hold the bending plate 306 and align the limiting hole 307 with the synchronization hole 304. Then, pass the pulling tube 311 through the limiting hole 307, the synchronization hole 304 and the avoidance hole 302 to achieve interlocking of the docking plate 303, the pulling tube 311 and the bending block 301.

[0036] Then, the threaded column 309 is rotated, which pushes the extrusion pad 310 to move and fit tightly against the clearance hole 302. Under the reaction force, the bending plate 306 drives the pulling tube 311 to move slightly within the synchronization hole 304.

[0037] Since the synchronization hole 304 is elliptical, the pulling tube 311 pulls the bending block 301 through the avoidance hole 302, thereby making the first template 1 and the second template 2 fit together more tightly and increasing the stability of the splicing.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
