After the prefabricated columns 4 are hoisted in place, the prefabricated columns 4 are installed on the concrete slab 9 .

The following is an explanation of the specific steps of an in-plane construction process for frame structures:

The first step: in-depth design of protective device 1 for in-plane operations

According to the floor height, side beam height and column position, the size of the inner working protection device 1 should be deepened to adapt to the construction of the main structure of the corresponding building; the position of the column installation platform 3 needs to reserve installation space and corresponding closing components. The structural composition of the in-plane work protection device 1 is shown in Figure 8, and the protection length and height are adjusted according to the actual situation.

Step 2: Lift and install the in-plane work protection device 1

The in-plane operation protection device 1 is lifted to the surface of the concrete slab 9 to be installed with the help of vertical transportation equipment such as a tower crane or a truck crane, and is connected to the surface of the concrete slab 9 through the bottom fixing device 105 and the diagonal tie rod 104, and the ground anchor 107 may be in the form of an anchor ring 1051 or an embedded nut; the final installation form of the in-plane operation protection device 1 is shown in Figure 1 .

The opening and closing piece 1011 of the in-plane work protective device 1 is completed by the protective connection tool 2. The structural composition of the protective connection tool 2 is shown in Figure 11. The connecting rod 202 is fixed on the protective mesh on one side through the fixing piece 201, and the locking piece 203 The protective mesh fixed on the other side. By rotating the connecting rod 202, the connection between the mesh sheets can be locked and unlocked.

Step Three: Installation and Inversion of Column Working Platform 3

Lift the column work platform 3 to the corresponding position with the help of vertical transportation equipment. The protective mesh at the installation position of the platform uses an openable and closable structure. When the column work platform 3 is installed, it is opened. The operator holds the column work platform 3 and lifts it into place. The working platform 3 is fixed to the surface of the concrete slab 9 through anchor rings 1051 and the like; as shown in Figure 2 after the installation is completed.

During the installation of the column work platform 3, work such as measuring and setting out, cutting hair, inserting bars, etc. can be carried out at the same time; not all of the column work platforms 3 can be installed and used in different working areas. After the column work platform 3 is dismantled, the corresponding positions should be immediately removed. The opening and closing protective mesh is closed and connected and fixed.

Step 4: Hoisting of prefabricated column 4

After the column working platform 3 is installed and accepted, the precast column 4 can be hoisted. Before the precast column 4 is hoisted, the pre-installation of the corresponding sleeve components must be completed; if the longitudinal steel bars of the precast column 4 are mechanically connected, it needs to be completed with the help of the column working platform 3. The operator completes the external steel bar connection operation through the working surface provided by the column working platform 3. After the prefabricated column 4 is installed, it is shown in Figure 3.

Step 5: Installation of the column bottom outer mold of prefabricated column 4

Relying on the column work platform 3, transport the column bottom outer mold 5 to the outer bottom of the prefabricated column 4, adjust the position of the L-shaped tool mold 501 of the column bottom outer mold 5 so that it fits the structural surface of the prefabricated column 4 and the column bottom outer mold 5 The bottom support member 503 is placed on the surface of the concrete slab 9 . Rotate the rotating member 502 on the top of the column bottom outer mold 5 so that it hugs the external corners of both sides of the prefabricated column 4, tighten the fixing bolts 504, and insert the locking pin into the locking hole 5011. The structural form of the column bottom outer mold 5 is shown in Figure 17. The working condition after the column bottom outer mold 5 is fixed is shown in Figure 4.

After the outer mold 5 at the column bottom is fixed, the column working platform 3 can be lifted and transferred to the lower working point (as shown in Figure 6); after the column working platform 3 is removed, the opening and closing piece 1011 is reset, and the protective connection tool 2 is used to connect the two The side mesh panels are connected and fixed.

The column bottom outer mold 5 of the prefabricated side columns can be installed without the assistance of the column work platform 3. Place the column bottom outer mold 5 sideways on the side of the prefabricated side column, and flip the column bottom outer mold 5 so that it is close to the prefabricated column 4. The support members 503 of the structural surface and column bottom outer mold 5 are placed on the surface of the concrete slab 9 . Rotate the rotating part 502 on the top of the column bottom outer mold 5 so that it hugs the external corners of both sides of the prefabricated column 4, tighten the fixing bolts, and insert the locking pin into the locking hole 5011. The installation process is as shown in Figure 19 and Figure 20 Show.

The inner mold of the column base and the in-plane column base mold of the prefabricated side columns and prefabricated corner columns will be completed according to the actual situation after the acceptance of the steel bars, and are the same as ordinary construction techniques. Among them, the column bottom molds of prefabricated side columns and prefabricated corner columns include column bottom outer molds 5 and column bottom inner molds.

Step Six: Lifting of Side Beam Mold

The side beam mold 8 is assembled by custom mold components on the surface of the concrete slab, and is hoisted as a whole with the help of vertical transportation equipment such as tower cranes or truck cranes; after the hoisting is completed, it is shown in Figures 7 and 21.

The side beam mold uses an in-plane tensile reinforcement structure to avoid leaning between the side beam mold 8 and the in-plane work protection device 1 to complete the construction work; the side beam outer mold 801 of the side beam mold is pre-installed with a preset nut 803, which is welded with one end The nut's pulling screw 805 can achieve the purpose of disassembling and assembling the screw in the working surface, as shown in Figures 16 and 17.

The side beam mold 8 can include the beam and column node positions and the molds can be hoisted in a unified manner. The docking of the side beam outer mold 801 can be completed using the docking tool 11. The structural form of the docking tool 11 is shown in Figures 24 to 29.

The in-plane beam mold 7 uses wood molds, aluminum molds, etc. according to on-site requirements, and is completed in-plane. There is no edge work, and normal construction techniques can be followed.

Step 7: Steel and concrete work

The beam steel bars 6 and plate steel bar binding are all completed under the protection of the in-plane work protection device 1, and the process is consistent with ordinary cast-in-situ construction; the installation of embedded components such as embedded parts 1501 is completed during the plate steel bar construction stage.

Concrete pouring is completed under the protection of the in-plane operation protection device 1, and the process is consistent with ordinary cast-in-place construction. The situation after the concrete pouring is completed is shown in Figure 8.

Step 8: Removal of the side beam mold

After the concrete pouring is completed and reaches the removable form strength, the outer mold is removed. The outer mold mainly includes the edge beam outer mold 801 and the column bottom outer mold 5.

Lift the floor lifting equipment 10 to the surface of the poured concrete slab 9. The removal of the side beam outer form 801 requires the cooperation of two floor lifting equipment 10; the floor lifting equipment 10 is placed on both sides of the side beam outer form 801 to be removed. , the hook of the floor lifting equipment 10 is connected to the side beam outer mold 801, remove the pull screw 805 on the inside of the side beam, and then connect the docking tooling 11 of the side beam outer mold 801, the pin pins and other connecting accessories connected to the side beam bottom mold. During disassembly, if the edge beam outer mold 801 is tightly adhered to the structural surface of the edge beam, a crowbar can be used to assist the edge beam outer mold 801 to separate from the concrete.

After the side beam outer form 801 is detached, the floor lifting equipment 10 is started to lift the side beam outer form 801 from the gap between the in-plane work protection device and the concrete structure to above the surface of the concrete slab 9, and the floor lifting equipment 10 is pushed to transfer the outer mold to Inside the concrete slab 9, the workers clean the outer molds and stack them together. The dismantling conditions are shown in Figure 9, Figure 10 and Figure 30.

The side beam inner mold 806 of the side beam can be dismantled simultaneously when the side beam outer mold 801 is removed. The beam bottom mold and support system must have structural strength that meets the mold removal requirements before completing the disassembly work.

Step 9: Removal of the outer mold 5 at the bottom of the column

Move the floor lifting equipment 10 to the corner column position, and connect the hook of the floor lifting equipment 10 with the L-shaped mold 501 of the column bottom outer mold 5. When the column bottom outer mold 5 is unbalanced, you can use a sling to assist; Remove the accessories connecting the mold 501 and the inner mold at the bottom of the column. Then remove the locking pin at the rotating part 502 at the top of the L-shaped mold 501, and rotate the rotating part 502 to a loose state, such as the structure of the outer mold 5 at the bottom of the column and the column. If the surface is tightly adhered, you can use a crowbar to assist the outer mold 5 at the bottom of the column to separate from the concrete surface.

After the outer formwork 5 at the column bottom is detached, start the floor lifting equipment 10, lift the outer formwork 5 at the column bottom from the gap between the in-plane work protection device 1 and the concrete structure to above the surface of the concrete slab 9, and push the floor lifting equipment 10 The column bottom outer mold 5 is transferred to the inside of the concrete slab 9, and the operator cleans the column bottom outer mold 5 and then stacks them together. The dismantling conditions are shown in Figure 31 and Figure 32.

Step 10: Erection of construction layer edge protection device 12

Before the in-plane operation protection device 1 is dismantled and transported, an edge protection device 12 needs to be erected at the edge position of the concrete structure. The edge protection device 12 can be in the form of steel pipe protection, ordinary shaping protection, etc. After the installation is completed, it is shown in Figure 33.

After the edge protection device 12 is erected and the cast-in-place mold is dismantled, the second step of lifting and installation of the in-plane operation protection device 1 is carried out according to the on-site progress, and the second to tenth steps are cyclically operated on each layer. The working conditions after the protection lifting is completed are shown in Figure 34.

The overall construction process of the above-mentioned construction technology is: lifting and installing the in-plane work protection device 1→installing the column working platform 3→installing the prefabricated column 4→installing the column bottom outer mold of the prefabricated column 4→setting up the support system→edge Hoisting of beam mold → Installation of in-plane beam and floor mold → Installation of beam and plate steel bar binding → Installation of embedded components such as embedded parts 1501 → Pouring of cast-in-place concrete → Dismantling of cast-in-place mold; the above process is cycled on each floor.

The vertical structure of the frame structure uses prefabricated components to avoid the use of a large number of molds during the vertical construction process. The longitudinal reinforcement connection of prefabricated columns and other processes that must be completed externally are completed using a work platform to assist; the nodes at the bottom and top of the columns are used with the surface. Customized molds are used for internal operations, and the mold installation and disassembly are all completed within the working surface; the side beams are hoisted as a whole and dismantled in pieces using the mold, so that installation and dismantling operations can be completed without relying on the external working surface. With the overall cooperation of the above-mentioned processes, external protection is simplified, and customized in-plane work-shaped protective railings are used to complete edge protection during the operation.

Through the above-mentioned in-plane construction method, the construction of the main structure of the frame can be completed without external scaffolding, which can simplify the external protective facilities, ensure the protective effect while making the protection lightweight and simple, reducing the cost of protective facilities; it can speed up The installation and removal of protective facilities are efficient; the mold installation and removal operations can be completed without an external working surface. Through the various types of tooling and molds described above, the purpose of in-plane construction is achieved, which effectively solves how to complete the construction of the main structure without relying on external working surfaces, how to speed up the installation and removal of protective facilities, and how to complete the construction without external work. Complete the mold installation and disassembly operations under surface conditions and how to simplify the external protection facilities to make them as lightweight and simple as possible while meeting the protection requirements.

It should be noted that the floor lifting equipment 10 can be replaced by vertical transportation equipment such as tower cranes and truck cranes.

In addition, in other alternative embodiments, the in-plane work protection device 1 can also be attached to the prefabricated column 4, and the protection height is adjusted according to the floor height. The structure is shown in Figures 35 to 38. The premise of this alternative method is that the precast column 4 is firmly connected to the concrete slab 9 and can bear the protective load; the overall construction process of this alternative method is: measurement and setting → installation and installation of the column working platform 3 → installation of the precast column 4 → prefabrication Installation of the outer formwork at the bottom of column 4→Erection of the edge protection device→Installation of the in-plane operation protection device 1→Erection of the support system→Integral hoisting of the edge beam mold→Installation of the in-plane beam and floor mold→Beam and plate steel bar binding Installation→Installation of embedded components such as embedded parts 1501→Pouring of cast-in-place concrete→Removal of cast-in-place molds; the above construction process is cycled at each layer. The construction process of this alternative method is similar to the above-mentioned in-plane construction method, only the surface The attachment method and installation time of the internal work protection device 1 are different.

It should be noted that in related technologies, the construction of frame structures requires the assistance of external landing scaffolds, cantilever frames or climbing frames, and part of the main structure construction operations are completed on the external working surface, which has great construction limitations. By using prefabricated components, tooling, molds and supporting construction techniques, the present invention can complete all main structure construction operations of the frame structure without relying on external scaffolding working surfaces.
