Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to a single-sided truss steel formwork for walls and a steel formwork for wall construction. Background Technology

[0002] With the rapid development of the construction industry, high-rise buildings and large-span structures are becoming increasingly common, placing higher demands on formwork systems during concrete wall pouring. Steel panels, due to their smooth surface, high strength, and good rigidity, can effectively ensure the accuracy and verticality of wall structures. Furthermore, their recyclability and rapid construction process give steel formwork significant advantages in building construction.

[0003] One common type is the wall tie-beam formwork system. This system mainly consists of steel panels, longitudinal and transverse joists, and through-wall tie bolts connecting the formwork on both sides of the wall. The through-wall tie bolts are used to adjust the verticality of the steel panels on both sides of the wall, and the structure is relatively simple. However, after the wall tie-beam formwork is removed, numerous tie bolt holes are left in the wall, requiring subsequent sealing. If the wall is used in special environments such as water storage stations or pumping stations, the waterproofing requirements for sealing these numerous bolt holes will be even higher. Even after prolonged use, there is still a risk of leakage, increasing the difficulty and cost of later maintenance. Utility Model Content

[0004] The purpose of this invention is to address the problems of high maintenance costs and difficult waterproofing construction associated with existing steel formwork systems, which require extensive waterproofing and repair after dismantling, especially in water-related applications. This invention provides a single-sided truss-type steel formwork and a construction steel formwork for walls. This new system eliminates the need for through-wall tie bolts for vertical adjustment. Instead, it utilizes truss units with a certain width and rigidity as the support structure, employing adjustable vertical and diagonal support mechanisms to adjust the verticality. This design is convenient, reduces the number of bolt holes requiring repair on the constructed walls, prevents leaks, and lowers maintenance costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A single-sided truss-type steel formwork for walls, comprising steel panels;

[0007] The truss unit includes a first side facade and a second side facade arranged opposite to each other. The first side facade is fixedly connected to the steel panel. A vertical support mechanism is connected to the bottom end of the second side facade, and an oblique support mechanism is connected to the second side facade. The lengths of the vertical support mechanism and the oblique support mechanism are adjustable.

[0008] This utility model provides a single-sided truss-type steel formwork for walls, comprising a steel panel and truss units. The truss units serve as supports for the steel panel and are fixedly connected to the steel formwork. In use, the bottom of the facade of the truss unit closest to the steel panel is fixedly connected to the wall or base. The bottom of the facade of the truss unit furthest from the steel panel is provided with a vertical support mechanism connected to the base, and a diagonal support mechanism is provided in the middle connected to the base. The entire single-sided truss-type steel formwork has a simple structure, utilizing truss units with a certain width and rigidity as supports for the entire steel formwork. The verticality of the steel panel is adjusted using adjustable vertical and diagonal support mechanisms. The steel panel is used as a cavity template for concrete pouring in the wall. This truss-type steel formwork is easy to operate, and the constructed wall will not have a large number of bolt holes that need repair, avoiding water leakage, reducing later maintenance costs, and facilitating widespread application.

[0009] In a preferred embodiment of this utility model, a steel section is provided between the steel panel and the first side facade, the steel section comprising a plurality of steel strips arranged longitudinally at intervals. Preferably, the plurality of steel strips are arranged at equal intervals longitudinally. Further, the steel strips include angle steel strips or channel steel strips.

[0013] As a preferred embodiment of this utility model, an operating platform is provided at the top of the first side facade and the second side facade, and a railing is provided on the upper part of the side of the operating platform away from the wall.

[0014] As a preferred embodiment of this utility model, a ladder is provided in the middle of the truss unit.

[0015] Another objective of this utility model is to provide a wall construction steel formwork including the above-mentioned single-sided truss steel formwork.

[0017] During construction, two opposing truss-style steel formwork panels on one side of the wall are combined to form a construction steel formwork unit. A concrete pouring space is created between the two panels. After the concrete is poured, the steel panels act as a retainer for the concrete. Once the concrete has cured, the supporting surface of the steel formwork forms a flat wall side. The structure is simple, the operation is convenient, and the wall side has a high degree of flatness.

[0018] As a preferred embodiment of this utility model, the feature is that a concrete pouring space is formed between the two steel panels, and the two steel panels respectively abut against the steel bars pre-embedded in the concrete pouring space.
