Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a cage-form assembly integral vertical main structure and a construction method thereof. Background Art

[0002] Formwork and reinforcement engineering are two crucial sub-projects in the main building project. Relevant research has measured the construction time of relevant sub-projects in the standard layer of residential construction projects, and found that the time spent on formwork and reinforcement engineering accounts for the largest proportion, and the combined time of the two accounts for about 50-70% of the construction time of a standard layer. And the larger the amount of reinforcement engineering (high-density reinforcement), the more important this link is, but in actual engineering, the project schedule cannot allow any time to be wasted. These two time periods can be targeted for technical optimization. For example, the current main push for formed reinforcement technology in reinforcement engineering can better solve the problem of time-consuming on-site production of traditional reinforcement, but it is limited by factors such as equipment manufacturing, transportation and storage.

[0003] In recent years, many new prefabricated building technology systems have emerged in China, such as "core-cast prefabricated concrete shear wall structure technology", "form-free assembly integrated reinforced concrete structure system" and "SPCS fully prefabricated building system". The common technical features they have can be simply summarized as: cavity, connector and cast-in-place. Taking the above-mentioned "form-free assembly integrated reinforced concrete structure system (PI system)" as the narrative object, from the perspective of its component production process, a single prefabricated component generally requires flipping, pouring, equal strength, and demolding. The production efficiency is very low, which is not conducive to industrial assembly line production, and its component price is not lower than that of general prefabricated components. Similarly, the application of PI cage molds in engineering is also difficult to avoid the dilemma encountered by the current prefabricated building technology. Summary of the invention

[0080] In summary, first, the cage mold assembly integral vertical main structure 100 of the present invention combines the template 4 and the steel bar 3 into a whole, which can be integrated in the factory (nomadic production) to become a self-balancing column cage mold prefabricated part, realizing the transformation of the traditional column steel bar binding harsh construction environment (construction work surface) to the indoor environment, and the prefabricated parts are easy to produce, which can realize the industrialized production of prefabricated parts, reduce production costs, reduce on-site labor input, and reduce construction time. Second, the present invention utilizes the first clamp device 1 and the second clamp device 2, and adopts the first tight top member 11 and the second tight top member 21 to tightly fix on the steel bar 3, without binding, which improves work efficiency and avoids the displacement, deformation, distortion, dislocation, and falling off problems that occur during the lifting process of the traditional binding steel bar skeleton. Third, the formed cage mold prefabricated part can improve the quality of the project, and the clamps and plastic pads provided make the steel bar spacing of the cage mold prefabricated part and the thickness of the protective layer between the steel bar and the template 4 achieve unified specifications. Fourth, the formed cage form prefabricated parts are transported to the construction site and hoisted. The weight of the components is only about 1 / 8 of the current solid components of precast concrete columns. They have high strength and can be installed quickly. Fifth, the concrete is poured at one time. The integrated cage form prefabricated parts form a self-balancing and stable system to bear the construction load, which greatly simplifies the support construction. The integrity and connection safety are completely consistent with the traditional cast-in-place structure, which is equivalent to the cast-in-place structure. It has the characteristics of no building formwork 4 and no construction waste. At the same time, it has good compatibility with concrete and will not affect the structure. Sixth, the formwork 4 uses FRP plates that can greatly improve the strength of reinforced concrete components. After the construction is completed, they are not removed and become one with the main structure. The exterior facades of the FRP column cage formwork system are all smooth glass fiber reinforced plastic walls (can be treated with paraffin or gel coat), and the surface flatness effect is good (the paint adhesion is poor, but thin stickers or veneer cavity wrapping can solve the exterior decoration problem). Seventh, the combination of FRP and steel-concrete structure can greatly improve the bearing capacity of the structure. Therefore, the design cross-section of its components will be greatly reduced and the cost of traditional formwork 4 will be reduced. In general, the total cost is easy to be accepted by the construction party. Eighth, the FRP cage formwork system solves the important problem of the difficulty in obtaining the evaluation score of vertical components in the evaluation standards for prefabricated buildings, and meets the requirements of the evaluation guidelines for prefabricated buildings. Ninth, the FRP column cage formwork system is bold, especially for construction, which solves the two major problems of concrete structure steel bars and on-site formwork 4 production, greatly reducing the occupation of this sub-project on the construction work surface and shortening the critical time period.
