Description

Technical Field

[0001] This utility model relates to the field of prefabricated support formwork technology, specifically a non-removable formwork shell that can be used for support. Background Technology

[0002] In traditional construction projects, support structures typically rely on wooden or steel formwork for construction. However, this method has many limitations, not only increasing construction costs but also posing challenges in terms of construction quality and efficiency.

[0003] First, traditional support systems require large quantities of timber or steel as formwork materials, which not only consumes significant resources but also significantly increases material procurement costs at the beginning of a project. This is especially true in large-scale projects where the low reuse rate of formwork further exacerbates the cost burden. Furthermore, the transportation, installation, and dismantling of these materials consume considerable manpower and time, indirectly driving up the overall cost.

[0004] Secondly, traditional formwork has limited support strength and is prone to damage during construction. Especially in complex geological conditions or harsh weather environments, the stability of the formwork is difficult to guarantee, leading to a decline in construction quality. For example, the pressure during concrete pouring may cause the formwork to deform or even crack, thereby affecting the overall structural safety and durability of the building.

[0005] Furthermore, the formwork and support system for the wall are complex, involving a large amount of work and numerous steps. To ensure the stability of the formwork, construction workers need to spend a significant amount of time and effort on precise positioning and reinforcement. This not only extends the construction period but also increases the difficulty of on-site management and coordination. The complex support system may also occupy more space, restricting the parallel execution of other processes and further slowing down the overall progress.

[0006] Finally, after traditional formwork is removed, the wall surface is often not smooth enough, requiring secondary treatment. Typically, the construction team needs to re-plaster or re-tile to repair surface defects. This process not only increases the workload but may also introduce new quality problems, such as hollow areas and cracks. These subsequent repair measures not only prolong the construction period but also lead to unnecessary material waste and environmental pollution.

[0007] In summary, traditional support methods have significant shortcomings in terms of cost, quality, efficiency, and environmental protection, and there is an urgent need to provide a non-removable formwork for support to solve these problems. Summary of the Invention

[0008] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a non-removable formwork shell that can be used for support, so as to solve the problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a non-removable formwork shell that can be used for support, comprising multiple formwork shell units, each formwork shell unit consisting of a non-removable shell and tie steel sheets, with opposing non-removable shells connected by multiple tie steel sheets, the two ends of which are pre-embedded in the non-removable shells on both sides, and the non-removable shell being a precast steel-concrete plate structure.

[0010] Preferably, the non-removable shell is provided with a steel mesh, which is composed of longitudinal and transverse steel bars.

[0011] Preferably, the cross-section of the tie steel sheet is U-shaped, and the bent portions at both ends of the tie steel sheet are hooked onto the reinforcing mesh.

[0012] Preferably, the outer surface of the non-removable shell is smooth, and the inner surface is rough.

[0013] Preferably, the shells that do not require disassembly are connected by a tongue-and-groove interlocking structure, and the connection is reinforced with mortar.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] See Figure 1 and Figure 4 A non-removable formwork for support is disclosed, comprising multiple formwork units. Each formwork unit consists of a non-removable shell 1 and connecting steel plates 2. Opposing non-removable shells 1 are connected by multiple connecting steel plates 2, with both ends of the connecting steel plates 2 pre-embedded in the two non-removable shells 1. The non-removable shell 1 is a precast reinforced concrete slab structure. This structure allows for the pre-design and prefabrication of formwork units of different sizes in a factory for projects of varying scales, achieving standardized production. It also possesses advantages of being green, low-carbon, and environmentally friendly, and can be used for the renovation of old walls and the casting of frame structure walls in new buildings, comprehensively improving the overall benefits of construction projects.

[0026] Preferably, the non-removable shell 1 contains a reinforcing mesh 3, which is composed of longitudinal reinforcing bars 301 and transverse reinforcing bars 302. The longitudinal reinforcing bars 301 and transverse reinforcing bars 302 can be connected to form the reinforcing mesh 3 through processes such as binding and welding.

[0027] Preferably, the tie steel sheet 2 has a U-shaped cross-section, with the bent ends of the tie steel sheet 2 hooked onto the reinforcing mesh 3. The tie steel sheet 2, with its ends fastened to the reinforcing mesh 3, enhances the support strength. During concrete pouring, it resists the lateral pressure of the concrete on the formwork, acting as a reaction force, and simultaneously improves the overall strength after pouring. The size and quantity of the tie steel sheet 2 can be adjusted according to the actual needs of the support structure.

[0028] Preferably, the outer surface of the non-removable shell 1 is smooth, and the inner surface is rough.

[0029] Preferably, the non-removable shells 1 are connected by a tongue-and-groove interlocking structure, and the connection is reinforced with mortar. This further enhances construction standardization, improves installation accuracy, and increases support strength.

[0030] Preferably, both the longitudinal reinforcing bars 301 and the transverse reinforcing bars 302 are cold-rolled plain reinforcing bars. Different specifications and quantities of cold-rolled plain reinforcing bars can be selected according to the prefabricated support structure.

[0031] The working principle of this embodiment is as follows:

[0032] When this utility model is prefabricated in the factory, the main building steel cage is placed into the pre-support space of the formwork unit. The main building steel cage is installed when the steel mesh of the formwork itself is tied. When the two facades of the formwork are prefabricated, they are laid flat on the ground for formwork support and precasting. After the prefabrication is completed, the components are transported to the construction site and installed and supported according to the preset position. When the formwork unit is installed, mortar is applied to the concave and convex joints. The steel cage joints inside the formwork unit are tied with steel wire for a second time. After the support is installed to a suitable height, the pouring begins. The construction is completed after the pouring is completed.

[0033] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
