Description

Technical Field

[0001] This invention relates to the field of steel formwork technology for bridge piers, specifically a vertical splicing structure for steel formwork for high-speed railway pier caps. Background Technology

[0002] The vertical splicing structure of the high-speed railway pier cap steel formwork refers to the steel formwork being placed vertically and connected by vertical splicing during installation. This structural design ensures the stability and firmness of the steel formwork, while also improving construction efficiency and quality.

[0003] Vertical joint structures are usually fixed by bolts or welding to ensure that the connection between steel formwork is firm and reliable. However, steel formwork is easily affected by various factors during installation and use, such as temperature changes, structural deformation, improper installation, material problems, and wear and tear from long-term use. These factors can cause the joints between steel formwork to widen. Once the joints between steel formwork widen, it can lead to leakage during pouring, which will not only affect the quality of the project, but also delay the construction progress. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vertical splicing structure for steel formwork of high-speed railway pier caps, which solves the technical problem that the splicing joints between steel formwork are prone to become too large under the influence of external factors.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vertical splicing structure of steel formwork for high-speed railway pier caps, including two sets of steel formwork 1 and two sets of steel formwork 2, the two sets of steel formwork 1 and two sets of steel formwork 2 form a closed shape, a splicing joint is formed at the connection between the two sets of steel formwork 1 and two sets of steel formwork 2, and a dynamic splicing structure for compensating the gap of the splicing joint is provided at the connection between the two sets of steel formwork 1 and two sets of steel formwork 2;

[0006] The dynamic joint structure includes at least two elastic compensation units and a joint plate. The elastic compensation units are installed on the side wall of the steel template near the connection point. The elastic compensation units are connected to the joint plate, which is inserted into the joint.

[0007] Preferably, the elastic compensation unit includes a fixed frame, one end of which is provided with a bolt, which is installed in a screw hole opened on the steel template. The other end of the fixed frame is fitted with a movable column, one end of which is threaded with an adjusting nut. A compensation spring is provided between the adjusting nut and the fixed frame and sleeved on the outer wall of the movable column. The other end of the movable column is provided with a groove, which is inserted into the splice plate. Both sides of the groove are provided with insertion holes, and fixing pins are inserted into the insertion holes. Both ends of the fixing pin are threaded with fixing nuts.

[0008] Preferably, the splicing plate is integrally formed from a straight plate and a triangular plate, and the straight plate has a connecting hole for the fixing pin to pass through, and the straight plate is located inside the splicing seam.

[0009] Preferably, the two sides of the triangular plate are equilateral.

[0010] Preferably, both the first and second steel templates have inner inclined surfaces on their inner sides near the splice joint, and the two sides of the triangular plate are respectively attached to the two inner inclined surfaces.

[0011] Preferably, the connection between the steel template one and the steel template two is provided with an outwardly protruding edge, and the outer wall of the edge of the steel template one and the steel template two are respectively provided with a plurality of corresponding slots one and slot two, and buckles are inserted into the corresponding slots one and slot two.

[0012] Preferably, the buckle has a "U" shaped structure, and each end of the buckle is provided with a fixing foot.

[0013] Preferably, both the first card slot and the second card slot are "L" shaped structures.

[0014] By employing the above technical solution, the present invention provides a vertical splicing structure for steel formwork of high-speed railway pier caps, which has at least the following beneficial effects:

[0015] 1. The vertical splicing structure of the steel formwork for the high-speed railway pier cap features a dynamic splicing structure. When the splice between steel formwork one and steel formwork two widens, the splice plate is actively pulled outward by the elastic force of the compensating spring. Since the two sides of the triangular plate on the splice plate are respectively attached to the inner inclined surfaces of the two splices, the splice plate can continue to be tightly attached to the splice, which can reduce the problem of leakage caused by the widening of the splice, ensure the quality of the project, and avoid delaying the construction progress.

[0016] 2. The vertical splicing structure of the high-speed railway pier cap steel formwork is achieved by setting buckles, which are then inserted into slot one and slot two to form a connection between steel formwork one and steel formwork two, ensuring a stable connection.

[0017] 3. The high-speed railway pier cap steel formwork has a vertical splicing structure, and each part adopts a modular structure, which is easy to disassemble and reassemble and can be reused. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The main reasons why excessively large joints may occur between steel formwork panels are as follows: 1. Temperature changes: Due to the thermal expansion and contraction of steel, temperature changes can cause changes in the dimensions of the steel formwork, potentially leading to larger joints. 2. Structural deformation: When the bridge structure is subjected to loads or other external forces, it may deform, affecting the position and dimensions of the steel formwork and thus increasing the size of the joints. 3. Improper installation: If the steel formwork is not installed strictly according to design requirements and construction specifications, it may result in inaccurate alignment or weak connections, leading to larger joints. 4. Material problems: If the steel formwork material has quality issues, such as defects or deformation, it may cause changes in the joint size. 5. Long-term wear and tear: During long-term use, the steel formwork may be affected by environmental and climatic factors, leading to surface wear or corrosion, which in turn affects the dimensions of the joints.

[0032] To address the problem of excessively large splice seams, the following describes, in conjunction with the accompanying drawings, some embodiments of the present invention, providing a vertical splice structure for steel formwork of high-speed railway pier caps.

[0033] Example 1:

[0034] Combination Figures 1-9 As shown, the present invention provides a vertical splicing structure for steel formwork of high-speed railway pier caps, including two sets of steel formwork 1 and two sets of steel formwork 2. The two sets of steel formwork 1 and two sets of steel formwork 2 form a closed shape, and a splicing joint 5 is formed at the connection between the two sets of steel formwork 1 and two sets of steel formwork 2. A dynamic splicing structure 3 is provided at the connection between the two sets of steel formwork 1 and two sets of steel formwork 2 to compensate for the gap of the splicing joint 5. After the two sets of steel formwork 1 and two sets of steel formwork 2 are assembled, a splicing joint 5 will be formed. Then, the dynamic splicing structure 3 is used to compensate for the gap of the splicing joint 5 that has increased due to factors such as temperature changes, structural deformation, improper installation, material problems, and long-term wear, thereby avoiding the problem of pouring leakage.

[0035] The dynamic joint structure 3 includes at least two elastic compensation units 31 and a joint plate 32. The elastic compensation units 31 are installed on the side wall of the steel template 1 near the connection. The elastic compensation units 31 can provide tension on the joint plate 32, and can pull the joint plate 32 outward when the joint 5 widens. The elastic compensation units 31 are connected to the joint plate 32, and the joint plate 32 can be placed inside the joint 5 to block the gap between the steel template 1 and the steel template 2. The joint plate 32 is inserted into the joint 5 at the connection between the steel template 1 and the steel template 2. Due to various factors, the joint 5 of the steel template will widen after assembly. The elastic compensation units 31 provide tension to the joint plate 32. After the joint 5 widens, the joint plate 32 will actively move outward to fill the widened gap. Since the widening ratio is uncontrollable, elastic compensation is used to solve the problem of the widening of the joint 5.

[0036] Specifically, the elastic compensation unit 31 includes a fixed frame 311. One end of the fixed frame 311 has a bolt 312, which is installed in a screw hole 12 on the steel template 1. The other end of the fixed frame 311 is fitted with a movable column 313. One end of the movable column 313 is threaded with an adjusting nut 315. A compensation spring 314, sleeved on the outer wall of the movable column 313, is located between the adjusting nut 315 and the fixed frame 311. The other end of the movable column 313 has a groove that inserts into the joint plate 32. Both sides are provided with insertion holes, and fixing pins 316 are inserted into the insertion holes. Both ends of the fixing pins 316 are threaded with fixing nuts 317. Using the elastic force of the compensating spring 314, the movable column 313 moves outward. The movable column 313 drives the splice plate 32 to move outward through the fixing pins 316. At this time, the splice plate 32 will be actively pulled outward. Since the two sides of the triangular plate 322 on the splice plate 32 are respectively attached to the inner inclined surface 51 of the two splice seams 5, the splice plate 32 can continue to be tightly attached to the splice seam 5.

[0037] Furthermore, the joint plate 32 is integrally formed from a straight plate 321 and a triangular plate 322. The straight plate 321 has a connecting hole 3211 for the fixing pin 316 to pass through. The straight plate 321 is located inside the joint 5. The setting of the connecting hole 3211 makes it convenient for the fixing pin 316 to pass through, thereby facilitating the connection between the movable column 313 and the joint plate 32.

[0038] Furthermore, the two sides of the triangular plate 322 are equilateral; the equilateral structure design allows the joint plate 32 to always fit against the inner inclined surface 51 of the steel template 1 and the steel template 2.

[0039] Furthermore, both steel formwork 1 and steel formwork 2 have inner inclined surfaces 51 on their inner sides near the splice joint 5, and the two sides of the triangular plate 322 are respectively attached to the two inner inclined surfaces 51. Since the two sides of the triangular plate 322 on the splice plate 32 are respectively attached to the inner inclined surfaces 51 of the two splice joints 5, when the splice joint 5 between steel formwork 1 and steel formwork 2 becomes larger, the splice plate 32 can continue to be tightly attached to the splice joint 5 after moving outward.

[0040] As can be seen from the embodiment, when the splice joint 5 between steel template 1 and steel template 2 becomes larger, the elastic force of the compensating spring 314 causes the movable column 313 to move outward. The movable column 313 drives the splice plate 32 to move outward through the fixing pin 316. At this time, the splice plate 32 will be actively pulled outward. Since the two sides of the triangular plate 322 on the splice plate 32 are respectively attached to the inner inclined surface 51 of the two splice joints 5, it can be ensured that the splice plate 32 can continue to be tightly attached to the splice joint 5.

[0041] Example 2:

[0042] Combination Figure 1 and Figures 7-9 As shown, based on Embodiment 1, the connection between steel template 1 and steel template 2 is provided with an outwardly protruding edge. The outer walls of the edges of steel template 1 and steel template 2 are respectively provided with multiple corresponding slots 11 and 21. Buckles 4 are inserted into the corresponding slots 11 and 21. The buckles 4 are used to engage with the slots 11 and 21 to form a connection between steel template 1 and steel template 2.

[0043] Specifically, the buckle 4 has a "U" shaped structure, and fixed feet 41 are provided at both ends of the buckle 4; the buckle 4 can form a connection between the steel template 1 and the steel template 2.

[0044] Specifically, both slot 11 and slot 21 are "L" shaped structures. The purpose of this design is that the fixing foot 41 of the buckle 4 can be inserted into slot 11 and slot 21, which can restrict the buckle 4 from moving outward and improve the stability of the buckle 4 connection.

[0045] As can be seen from the embodiment, the buckle 4 is first inserted parallel into the slot 11 and slot 21, and then the buckle 4 is hammered downwards until the fixing foot 41 is inserted into the slot 11 and the bottom of the slot, so that the connection between the steel template 1 and the steel template 2 can be formed by the buckle 4.

[0046] As can be seen from the above embodiments, the usage process of this device is as follows: First, assemble and align the steel template 1 and steel template 2. Insert the joint plate 32 into the joint 5 between template 1 and steel template 2. Then, insert the buckle 4 parallel into the slot 11 and slot 21, and hammer the buckle 4 downwards until the fixing foot 41 is engaged in the bottom of slot 11 and slot 21. The buckle 4 forms a connection between steel template 1 and steel template 2. Then, insert the fixing pin 316 into the insertion hole of the movable column 313 to connect the movable column 313 with the joint plate 32, and lock it with the fixing nut 317. Finally, connect the fixing frame 311 to the movable column 313 and secure it with bolt 3. 12. Fix the fixing frame 311, then install the compensating spring 314 and adjusting nut 315. Finally, perform the above operation on each connection position of steel template 1 and steel template 2 in sequence. When the splice seam 5 between steel template 1 and steel template 2 becomes larger, the elastic force of the compensating spring 314 will cause the movable column 313 to move outward. The movable column 313 will drive the splice plate 32 to move outward through the fixing pin 316. At this time, the splice plate 32 will be actively pulled outward. Since the two sides of the triangular plate 322 on the splice plate 32 are respectively attached to the inner inclined surface 51 of the two splice seams 5, it can be ensured that the splice plate 32 can continue to be tightly attached to the splice seam 5.
