[0002] In engineering construction operations, dividing the main structure of a project into multiple precast components is the main trend in the entire construction market. The on-site operation volume of construction sites using precast components is significantly reduced, and dust pollution and noise pollution are significantly reduced;

[0003] In on-site construction, building precast steel materials such as steel stirrups are usually hoisted to the construction operation surface, and the steel bars are laid using traditional splicing methods and fixed with binding wires. During the process of manufacturing stirrups, a large amount of steel bars are wasted due to the need to cut the steel coils and bend them according to different specifications. Moreover, this operation method requires a large amount of manual labor, so it will consume a large amount of manpower and material resources. On the other hand, manual binding is relatively slow, and the levels of workers vary, which may lead to uneven firmness of each structure of the building, affecting the project acceptance, and thus greatly reducing the efficiency of project construction;

[0004] Therefore, it is urgent to improve the reinforced concrete precast structure to solve the above existing problems. Summary of the Invention

At the same time, the precast slabs are fixed using support parts and hooks, which greatly improves the firmness of the building main body. Using the fixing parts and support parts, only the required lengths of column bars and beam bars need to be cut during the precast process, greatly reducing the waste of steel materials and eliminating the need for a large amount of manual laying, thereby greatly reducing the loss of manpower and material resources.

Detailed implementation manners

[0044] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0045] As Figures 1 - 6 shown, the split-type built-in reinforced concrete precast member structure provided in this embodiment includes a precast beam 1, a precast column 2, and a precast slab 3. The precast beam 1 includes beam reinforcement 11, a fixing member 12, and a cross buckle 13. A plurality of beam reinforcements 11 are clamped and connected into a whole through a plurality of evenly distributed fixing members 12. The cross buckle 13 is clamped at both ends of the beam reinforcement 11 through screws. The precast column 2 and the precast beam 1 are fixed in advance using fixing members 12 of different specifications, and then hoisted and spliced, greatly improving the efficiency of engineering construction. At the same time, the precast slab 3 is fixed using a support member 33 and a hook 32, greatly improving the firmness of the building main body;

[0046] The precast column 2 includes column reinforcement bars 21 and precast column fixing members 22. The precast beam 1 is clamped in the middle of the column reinforcement bars 21 through a cross-shaped buckle 13. The precast slab 3 includes slab reinforcement bars 31 and hooks 32. The hooks 32 are fixedly connected to both ends of the slab reinforcement bars 31. The precast slab 3 is hung on the upper side of the upper beam reinforcement bars 11 of the precast beam 1 through the hooks 32. A support member 33 is clamped and connected at the position where the transverse slab reinforcement bars 31 and the longitudinal slab reinforcement bars 31 intersect. Both the upper and lower ends of the support member 33 are clamped and connected to the slab reinforcement bars 31. By using the fixing member 12 and the support member 33, only the column reinforcement bars and beam reinforcement bars with the required lengths need to be cut during the precast process, greatly reducing the waste of steel. There is no need to spend a large amount of labor for laying, thus greatly reducing the loss of manpower and material resources. The split-type splicing and installation enables the forces on each structure of the building main body to be balanced, thereby greatly improving the quality of the engineering construction.

[0047] Further, as Figure 2 and Figure 3 shown, the fixing member 12 includes an upper fixing plate 121 and a lower fixing plate 122. A number of uniformly distributed bolts 123 are rotatably arranged inside both the upper fixing plate 121 and the lower fixing plate 122. A nut 124 is fixedly connected to the bottom of the lower fixing plate 122. The bolts 123 correspond to the nuts 124. The positions and distances of the bolts 123 can be adjusted according to the quantities of the column reinforcement bars 21 and the beam reinforcement bars 11, greatly improving the flexibility of the present invention and being applicable to precast components of various models and specifications.

[0048] Meanwhile, as Figure 2 and Figure 3 shown, a recess 125 is formed at the position of the fixing member 12 corresponding to the beam reinforcement bars 11. The inner wall of the recess 125 abuts against the outer side of the beam reinforcement bars 11, facilitating the fixation of the column reinforcement bars 21 and the beam reinforcement bars 11 and making each split-type reinforced concrete precast component more firm.

[0049] In addition, as Figure 1 and Figure 4 shown, the precast column fixing member 22 is obtained by equally magnifying the fixing member 12, greatly improving the applicable range of the fixing member 12, facilitating batch manufacturing and being suitable for large-scale popularization.

[0050] Furthermore, as Figure 1 、 Figure 5 and Figure 6 shown, the support member 33 includes a slab support column 333. Support caps 331 are clamped and connected to both the upper and lower ends of the slab support column 333. Slab reinforcement bar buckles 332 are formed at the positions of the support caps 331 and the slab support column 333 corresponding to the slab reinforcement bars 31. The inner side of the slab reinforcement bar buckles 332 abuts against the outer side of the slab reinforcement bars 31. The support member 33 replaces the functions of traditional wire tying and supporting bars, reducing the manufacture of supporting bars, lowering the labor intensity of the staff in the steel bar yard, and at the same time saving building materials such as steel and wire ties, which is beneficial to increasing the profit of the engineering construction.

[0051] Meanwhile, as shown in Figure 5 and Figure 6 , the slab support columns 333 are fixedly connected to the support caps 331 by screws and nuts, making the precast slab 3 more firm. The precast slab 3 is fixed by the support members 33. When workers perform other operations above it, it is not easy to cause collapse, avoiding adverse effects such as deformation of the precast slab 3 caused by later operations. In addition, different models of support columns can be replaced, which is beneficial to controlling the slab thickness and thus beneficial to controlling the project quality.

[0052] Furthermore, as shown in Figure 1 and Figure 5 , the hooks 32 are evenly arranged on the upper side edge of the precast slab 3, and can be bent and fixed when the hooks 32 are lapped with the beam bars 11, facilitating the installation of the precast slab 3, making the precast slab 3 and the precast beam 1 fixed as a whole, and also making the force of the entire split reinforced concrete precast structure more uniform;

[0053] In addition, as shown in Figure 1 , templates are attached to the edges of the precast column 2 and the precast beam 1 and the bottom of the precast slab 3, facilitating later pouring with concrete. The split installation combined with the integral pouring can effectively avoid the generation of concrete cold joints, further improving the construction quality, which is not only beneficial to the mid-term acceptance but also beneficial to the later third-party inspection.

[0054] As shown in Figures 1 - 6 , a forming method of a split built-in reinforced concrete precast structure is characterized by including the following steps;

[0055] Step 1: Use the fixing member 12 and the precast column fixing member 22 to splice the required number of beam bars 11 and column bars 21 together for standby;

[0056] Step 2: Use the hoisting equipment to lift the precast column 2 to the construction platform for fixing, install the cross buckles 13 at both ends of the beam bars 11, lift the precast beam 1 and splice the precast beam 1 to both sides of the precast column 2 to form a precast frame;

[0057] Step 3: Select appropriate slab bars 31 to overlap each other into two-layer meshes. Hooks 32 are arranged at both ends of the upper slab bars 31, and the two-layer slab bars 31 are supported by the support members 33 to prevent collapse;

[0058] Step 4: Lift the precast slab 3 and lap it on the upper side of the precast beam 1, and use tools such as a bar bender to fix the hooks 32 on the beam bars 11, and the precast slab frame can be formed;

[0059] Step 5: Attach templates to the periphery of the frame, and finally use a pump truck to pour concrete;

[0060] In Step 1, a large number of prefabricated parts of the required specifications can be spliced in advance. In Step 3, the support member 33 can be increased or decreased accordingly according to requirements, as long as the prefabricated parts reach the required strength and toughness.

[0061] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction.
