Description

Technical Field

[0001] This invention relates to the field of general building construction technology, specifically to a general-purpose modular ribbed plastic formwork system for housing construction and its installation method. Background Technology

[0002] Formwork construction plays a crucial role in concrete engineering. In cast-in-place concrete structures of building construction, formwork engineering typically accounts for 10%-20% of the cost of the concrete structure project, 30%-40% of the labor, and about 50% of the construction period. Its construction quality has a direct impact on the overall quality of the concrete project.

[0003] Currently, China's construction formwork market has formed a three-way balance between aluminum alloy formwork, plastic formwork, and traditional wooden formwork. However, these technologies originate from different development paths, resulting in significant technological gaps and inherent bottlenecks.

[0004] Aluminum alloy formwork dominates the standard floors of high-rise residential buildings due to its high precision and high turnover rate (over 200 times). Its core technology lies in the use of high-performance aluminum alloys through extrusion and precision machining, achieving standardized construction. However, this technological paradigm heavily relies on "standardization," revealing fundamental flaws of excessive rigidity and insufficient flexibility when facing increasingly diverse architectural designs, resulting in poor adaptability to non-standard working conditions.

[0005] As an emerging force, plastic formwork aims to solve the flexibility problem by leveraging the plasticity of polymer materials. However, its early development was in the imitation stage, with two major technical bottlenecks: First, materials science and engineering mechanics were disconnected, and the design was not differentiated according to the stress characteristics of the components, resulting in an imbalance between performance and cost; second, system design was lacking, and it was developed only as a "sheet material" rather than a "system," lacking efficient connection structures and complete specification support.

[0006] Traditional wooden formwork technology is ancient and its advantage lies in its extremely flexible processing, but this comes at the cost of high consumption and low efficiency. Its "quasi-disposable" usage mode runs counter to the green and efficient direction of modern industrialized construction.

[0007] In summary, the industry is caught in three core contradictions: the rigidity of aluminum formwork versus the need for flexible construction, the performance and cost of early plastic formwork, and the traditional model of wooden formwork versus sustainable development. The market urgently needs a next-generation formwork system solution that can break free from technological path dependence and achieve synergistic breakthroughs in versatility, reliability, economy, and environmental friendliness.

[0008] Plastic molds offer advantages such as high strength, high precision, small panel seams, light weight, convenient construction, short construction period, and high turnover rate, achieving the effect of finished or fair-faced concrete. Plastic molds are used for formwork in cast-in-place areas because they are lighter than steel molds and easier to install and disassemble; compared to wooden molds, they can be used more times, have higher strength, better molding quality, are energy-saving and environmentally friendly, and produce a smooth and even concrete surface after molding, achieving a plaster-free effect, which aligns with the core concepts of green building construction.

Foundation Leveling: Level the foundation with concrete; S3. Positioning and layout: According to the markings on the construction drawings, mark the positioning lines for template installation on the working surface; S4. Install the mold according to the drawing: Fix the plastic template according to the marked lines; S5. Template splicing: Use wrench 18 to splice the template; within the frame area, splice the long and short sides of the inner and outer templates in sequence, so that the back of each template is against the limiting hoop 35; insert the external corner mold 13 at the external corner of the outer template; and splice the internal corner mold 14 and the tee 15 at the internal corner of the inner template. S6. Frame erection: Select a suitable length of 35 limit hoop and erect the 35 limit hoop according to the position of the positioning line; S7. Overall reinforcement: The positioning mechanism 37 provided on the limiting hoop 35 cooperates with the positioning block 22 to form a building formwork system with the frame and the formwork. S8. Acceptance Inspection: Check the splicing gaps of the formwork, the degree of inclination of the formwork, and the fixation of the frame and formwork; check whether the position of the formwork is consistent with the positioning line and whether the size meets the requirements of the construction drawings. After confirming that there are no problems, proceed with the subsequent concrete pouring work.

[0039] Advantageously, in step S3, the idle main mold 11 and strip mold 12 are used as supports to raise the limiting clamp 35 to the required height; after the limiting clamp 54 and the positioning block 2222 are engaged, the template used for support is removed. The dimensions of the main mold 11 and strip mold 12 are fixed and can be flexibly adjusted and matched according to the required height.

[0040] Working principle of this invention: The template names and specific dimensions are as follows (unit: mm). The above template design specifications are general. The formwork should be arranged according to the engineering construction drawings. Different sizes require different formwork specifications.

[0041] The floor slabs and walls use 1000×1000×65 main formwork; beams and columns use 1000×300×65 and 1000×200×65 main formwork; smaller formwork such as strip formwork is used to compensate for dimensional differences. The internal corner mold comes in three sizes as a set and is used for floor slabs, walls, beams and columns. It can be converted and modified into various molds, such as 500×300×100 (65), 300×300×100 (65), and 200×300×100 (65) as a set, for a total of four sets. T-junctions are used at the four corners of the floor slab with matching internal corner molds.

[0042] Wrenches are used as fasteners for splicing templates, and different sizes of wrenches are used for splicing templates of different sizes.

[0043] When splicing templates, it is recommended to splice the templates first and then install the limit clamp 35 for templates with shorter lengths. For templates with longer lengths, it is recommended to install the limit clamp 35 first, adjust its accuracy, and then splice the templates. This will prevent the templates from undergoing excessive deformation due to the force on one end of the limit clamp 35.

[0044] During the overall reinforcement, the limiting hoop 35 and the main mold 11 are locked. In the initial state, the positioning mechanism 37 and the limiting hoop 35 are not connected. First, rotate the rotating sleeve 39, and the connecting rod 40 rotates with the rotating sleeve 39. Under the threaded engagement of the threaded part 41 and the moving plate 44, the moving plate 44 moves, bringing the moving plate 44 closer to the slider 50. The movement of the movable plate 44 drives the four limit clamps 54 to move through the transmission rod 53. The four limit clamps 54 spread out. At this time, the slider 50 is installed on the limit clamp 35 so that the center position of the four limit clamps 54 is aligned as much as possible with the positioning block 22 of the target main mold 11. After alignment, the rotating sleeve 39 is rotated in the opposite direction to move the moving plate 44 away from the slider 50. Because the baffle 52 restricts the movement direction of the limiting clamps 54, the limiting clamps 54 can only move within a plane parallel to the target main mold 11. The moving plate 44 drives the four limiting clamps 54 to converge via the transmission rod 53. After the limiting clamps 54 contact the positioning block 22, the mold supporting the limiting clamp 35 is removed. The limiting clamps 54 continue to move, and the position of the slider 50 is automatically corrected. The slider 50 slides adaptively on the limiting clamp 35, and the height of the limiting clamp 35 is also corrected, adaptively rising and falling until the limiting clamps 54 completely clamp the positioning block 22, completing the overall reinforcement. At this point, the template surrounded by the limiting clamp 35 is stable. After all templates are assembled, on-site casting is carried out.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made based on the technical essence of the present invention without departing from the scope of the present invention are all within the scope of the present invention.
