Description

Technical Field

[0001] This utility model relates to the field of template manufacturing technology, specifically to a steel template. Background Technology

[0002] In recent years, steel formwork and scaffolding have been promoted to replace wooden formwork and scaffolding in the construction industry and high-speed railway bridge construction. Steel formwork has greatly reduced the use of wood in construction, reduced the waste of resources, and can be reused and recycled, thus improving construction speed and quality.

[0003] To improve the strength of steel formwork, the steel formwork structure can refer to the formwork and formwork manufacturing method disclosed in CN108612303A. Two longitudinal ribs are welded together, and transverse rib connecting strips are welded together. The transverse rib edge strips are then welded to the side panels, surrounding panels and panels of the longitudinal ribs respectively.

[0004] Although the above structure enhances the strength, rigidity and deformation resistance of the panel, the longitudinal beams along the length of the steel formwork are only fixed to the side plates by transverse connecting strips and tie bars, resulting in low connection strength between the longitudinal beams and the bottom plate between the transverse connecting strips. Utility Model Content

[0005] To achieve the above objectives, one or more embodiments of this utility model provide the following technical solutions.

[0006] This utility model provides a steel formwork, including a base plate, side plates fixedly arranged on both sides of the base plate, sealing plates provided at both ends of the side plates, a number of horizontal ribs evenly arranged between the side plates and along the length of the base plate, a pair of longitudinal ribs passing through perpendicular to the horizontal ribs, face edges provided on both sides of the longitudinal ribs, and a pad plate provided above the face edges.

[0007] Further configured, the cross section of the transverse rib is a Z-shaped structure.

[0008] Further configuration involves providing face edges on both sides of the horizontal rib, with the horizontal rib fixedly mounted on the base plate via these face edges.

[0009] Further configured, the lower sidewall of the pad is connected to the bottom plate via the connecting surface edge.

[0010] Further configuration involves the longitudinal reinforcement having a triangular cross-section.

[0011] Further configuration involves providing face edges on both sides of the longitudinal reinforcement, with the longitudinal reinforcement fixedly mounted on the base plate via these face edges.

[0012] Further, the horizontal reinforcement is configured to have triangular grooves corresponding to the longitudinal reinforcement.

[0013] Further configuration includes the side panel and bottom plate being integrally formed, and the sealing plate and bottom plate being integrally formed.

[0014] Further configuration involves the side panels being perpendicular to the end plate.

[0015] Further configuration involves evenly distributed tapered pin holes on both sides of the side plate.

[0016] The beneficial effects of one or more of the above technical solutions:

[0017] By using transverse ribs to support the side plates on both sides of the base plate, and then longitudinal ribs are installed through the transverse ribs. Both the longitudinal and transverse ribs are fixed to the base plate by the side edges. Then, the side edges of the longitudinal ribs and the base plate are covered by pads. By using several pads evenly arranged along the length of the base plate, the connection stability between the longitudinal ribs and the base plate is enhanced. Attached Figure Description

[0023] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0024] A type of steel formwork, as shown in the reference Figure 1 and Figure 2 The system includes a base plate 1, side plates 2 fixedly installed on both sides of the base plate 1, sealing plates 3 at both ends of the side plates 2, several horizontal ribs 4 evenly arranged between the side plates 2 and along the length of the base plate 1, a pair of longitudinal ribs 5 running through the horizontal ribs 4 perpendicular to the horizontal ribs 4, face edges 7 on both sides of the longitudinal ribs 5, and pads 6 on top of the face edges 7. The base plate 1 is made of S550 zinc-aluminum-magnesium high-strength steel with a thickness of 1-2mm and the same weight as aluminum formwork of the same size, 25Kg per square meter. It provides stronger and more stable support through the triangular support force of the horizontal ribs 4.

[0025] The cross section of the horizontal rib 4 is a Z-shaped structure. The horizontal rib 4 has face edges 7 on both sides. The horizontal rib 4 is fixed to the base plate 1 through the face edges 7. The lower side wall of the face edge 7 is welded to the upper side wall of the base plate 1. The horizontal rib with the Z-shaped structure is hollow inside. Compared with the solid structure, the horizontal rib 4 can reduce the overall weight of the steel formwork after installation. At the same time, the Z-shaped structure provides longitudinal support to both sides along the face edges 7.

[0026] The lower sidewall of the pad 6 connects both the face edge 7 and the base plate 1. A portion of the lower sidewall of the pad 6 is welded to the upper surface of the side edge of the face edge 7, and another portion is on the base plate 1, allowing the longitudinal beam to be welded to the base plate 1 as a whole. The pad 6 is solid, and the ends of the pad 6 are simultaneously welded to the longitudinal beam and the base plate, further providing effective support between the longitudinal beams. The pad 6 connects the longitudinal beam and the base plate as a whole through welding, improving the connection stability between the longitudinal beam and the base plate.

[0027] The longitudinal reinforcement 5 has a triangular cross-section. The longitudinal reinforcement 5 has face edges 7 on both sides. The longitudinal reinforcement 5 is fixed to the base plate 1 through the face edges 7. The lower surface of the face edges 7 is welded to the upper surface of the base plate 1 to improve the connection stability between the longitudinal reinforcement 5 and the base plate 1. The longitudinal reinforcement 5 with triangular structure is hollow inside. Compared with solid structure, the longitudinal reinforcement 5 can reduce the overall weight of steel formwork after installation. At the same time, the triangular structure provides longitudinal support to both sides along the face edges 7.

[0028] The horizontal rib 4 has triangular grooves corresponding to the longitudinal rib 5. The spacing of the triangular grooves is greater than the width of the longitudinal rib 5, which facilitates the horizontal rib 4 passing through the triangular grooves of the longitudinal rib 5 during installation. The side plate 2 and the bottom plate 1 are integrally formed. The sealing plate 3 and the bottom plate 1 are integrally formed. The side plate 2 is perpendicular to the sealing plate 3. Several tapered pin holes 8 are evenly arranged on both sides of the side plate 2. The side plate 2 has asymmetrical tapered pin holes 8 on both sides to connect the adjacent steel templates. This replaces the welding of the left and right frames and the bottom plate 1. It is integrally formed and can be directly cut by forming and punching, replacing the welding of the left and right frames and the bottom plate 1. The triangular edge of the longitudinal rib 5 ensures the welding surface width and welding strength. The zigzag edge of the horizontal rib 4 has a better welding effect.

[0029] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
