Description

Technical Field

[0001] This invention relates to the field of building engineering, and in particular to a prefabricated assembled concrete frame and its assembly method. Background Technology

[0002] Currently, prefabricated green buildings align with the development theme of green buildings. Among them, precast concrete frame structures are a type of prefabricated building. Prefabricated buildings can effectively reduce construction waste and dust pollution, shorten the construction period, and reduce construction costs.

[0003] When using precast frames in construction, it is usually necessary to pre-embed connecting steel bars on the construction site. The precast frames are pre-drilled with mounting holes to match these connecting steel bars. During assembly, a crane is used to lift the precast frame, align the mounting holes with the connecting steel bars, and then the crane is used to slowly lower the precast frame, allowing the connecting steel bars to be inserted into the mounting holes, thus achieving initial fixation of the precast frame. After the precast frame assembly is completed, concrete is poured into the middle of the precast frame. After the concrete hardens, it forms a unified building structure with the precast frame.

[0004] Regarding the aforementioned technologies, the precast frame is mainly moved with the assistance of a crane during the assembly process. When the crane lifts the precast frame, the precast frame is prone to swaying with the crane rope, which can cause the precast frame to tilt during assembly, resulting in the bending or skewing of the steel bar connection ends and making the precast frame installation unstable. Summary of the Invention

[0005] To improve the installation stability of precast frames and reduce the probability of tilting during installation, this application provides a precast assembled concrete frame and an assembly method.

[0006] In the first aspect, this application provides a precast assembled concrete frame, which adopts the following technical solution: A precast concrete frame includes: a fixed base, with a limiting frame fixedly connected to the upper end of the fixed base. The limiting frame is hollow inside, and several insert rods are fixedly connected to the fixed base vertically, all of which are located within the limiting frame; a precast frame located at the upper end of the fixed base and adapted to the limiting frame, with connecting holes corresponding to the insert rods at the lower end of the precast frame, and a casting cavity and casting holes communicating with the casting cavity inside the precast frame; and two guide members located between the fixed base and the precast frame, the two guide members being symmetrically arranged and fitting together, with positioning devices fixedly connected to the lower end of the guide members. The positioning seat has a receiving groove adapted to the limiting frame. The limiting frame is located in the receiving groove and fits against the inner wall of the receiving groove. Each of the two guide members has a guide groove on the side that is close to each other. When the two guide members are connected, the two guide grooves are connected to each other and form a guide channel adapted to the precast frame. Each guide member has a clearance opening adapted to the pouring hole. The locking member is located between the two guide members. The locking member includes a threaded tube and a rotating block. The threaded tube is fixedly connected to the rotating block. Each guide member is fixedly connected with a semi-threaded column. When the two guide members are engaged, the two semi-threaded columns fit against each other and are adapted to the inner diameter of the threaded tube.

[0007] By adopting the above technical solution, the fixed seat is pre-embedded in an appropriate position, and two guide members are placed on the upper end of the fixed seat so that the positioning seat abuts against the upper end face of the fixed seat, thereby supporting the guide members. The two guide members are then connected, and the two guide grooves are connected. The limiting frame is located in the receiving groove, and the two semi-threaded columns are fitted together. The threaded tube is aligned with the two semi-threaded columns. By rotating the rotating block, the two semi-threaded columns are threadedly connected to the threaded tube. The threaded tube and the rotating block cooperate to limit the two semi-threaded columns, thereby limiting the two guide members. The precast frame is hoisted by a crane and inserted into a guide channel formed by two guide grooves. The precast frame is gradually lowered, and the two guide components work together to limit the precast frame, thereby reducing the probability of tilting or swaying during installation. After the lower end of the precast frame abuts against the fixing seat, the insertion rod is inserted into the connection hole, thus realizing the assembly of the fixing seat and the precast frame. Concrete is poured into the pouring cavity through the pouring hole. After pouring is completed, the pouring hole is sealed, thus completing the construction. The guide components support and guide the precast frame, which helps to reduce the probability of swaying or tilting during installation and improves the installation stability of the precast frame.

[0008] Optionally, the upper end of the guide member is provided with a variable diameter groove that communicates with the guide groove, and the diameter of the variable diameter groove gradually increases from bottom to top.

[0009] By adopting the above technical solution, when installing the prefabricated frame, the prefabricated frame enters the guide groove along the variable diameter groove, which helps to improve the convenience of the prefabricated frame entering the guide groove.

[0010] Optionally, the guide member has an installation groove, which is set from top to bottom along with the guide groove and the diameter-changing groove. Several support rollers are rotatably connected in the installation groove. The same guide belt is rotatably connected to the outside of the support rollers located in the same installation groove. A limit roller is rotatably connected at the connection between the guide groove and the diameter-changing groove. The limit roller is rotatably connected to the side of the guide belt away from the support roller.

[0011] By adopting the above technical solution, the support roller and the limiting roller cooperate to support the guide belt, so that the guide belt rotates around the support roller in the mounting groove. After the prefabricated frame comes into contact with the guide belt, the guide belt is driven to rotate by friction. The guide belt helps to reduce the rigid collision between the prefabricated frame and the guide component, thereby reducing the probability of damage to the prefabricated frame.

[0012] Optionally, a support column is fixedly connected to the upper end of the fixed base. The support column is inserted into the casting cavity and does not abut against the inner wall of the casting cavity. A transverse support block and a longitudinal support block are fixedly connected to the upper end of the support column. Both the transverse support block and the longitudinal support block abut against the precast frame.

[0013] By adopting the above technical solution, the support column supports the prefabricated frame through horizontal support blocks and vertical support blocks, thereby improving the connection stability between the prefabricated frame and the fixed seat.

[0014] Optionally, in one of the two guide members, a plurality of trapezoidal inserts are fixedly connected to each other, and the other guide member has trapezoidal slots that correspond one-to-one with the trapezoidal inserts. The trapezoidal inserts are inserted into the corresponding trapezoidal slots and fit against the inner wall of the trapezoidal slots.

[0015] By adopting the above technical solution, the trapezoidal insert and the trapezoidal groove cooperate to limit the two guides, thereby reducing the probability of slippage between the two guides and causing misalignment between the two semi-threaded columns, making it difficult to cooperate with the threaded pipe.

[0016] Optionally, the precast frame is provided with a first pouring pipe and a second pouring pipe. Both the first pouring pipe and the second pouring pipe are arranged vertically and parallel to each other. The pouring hole is connected to the first pouring pipe. The end of the first pouring pipe away from the pouring hole is connected to the second pouring pipe. The second pouring pipe has several discharge ports that are connected to the pouring cavity along the vertical direction.

[0017] By adopting the above technical solution, when concrete is poured into the pouring hole, the concrete flows upward along the first pouring channel. After entering the second pouring channel along the first pouring channel, it flows towards the lowest discharge port under the action of gravity. When the concrete in the pouring cavity submerges the lowest discharge port, the concrete fills the lower end of the pouring channel and is discharged from the upper injection port. The concrete gradually spreads from bottom to top, which helps to reduce the probability of cavities in the concrete in the pouring cavity.

[0018] Optionally, a flow passage cavity is provided at the lower end of the precast frame. The flow passage cavity is located between the casting pipe and the casting hole. The diameter of the flow passage cavity is larger than the diameter of the casting hole. A sealing plate adapted to the casting hole is provided in the flow passage cavity. The sealing plate is hinged to the precast frame.

[0019] By adopting the above technical solution, in the initial state, the sealing plate blocks the pouring hole. When concrete is introduced into the pouring hole, the concrete pushes the sealing plate away from the pouring hole, and the concrete enters the pouring pipe one along the flow cavity. When the pouring is completed, the supply of concrete into the pouring hole stops. At this time, the pouring channel one is full of concrete. Under the action of gravity, the concrete pushes the sealing plate to rotate towards the pouring hole, so that the sealing plate blocks the pouring hole, thereby reducing the probability of concrete leakage from the pouring hole.

[0020] Optionally, the lower end of the fixing seat has a fixing cavity, and the upper end of the fixing seat has a connecting cavity. The diameter of the connecting cavity is smaller than the diameter of the fixing cavity. One end of the connecting cavity is connected to the fixing cavity, and the other end is connected to the casting cavity.

[0021] By adopting the above technical solution, after the concrete enters the pouring cavity, it enters the fixed cavity along the connecting cavity. After the concrete solidifies in the fixed cavity and the connecting cavity, it helps to improve the connection strength between the precast frame and the fixed seat.

[0022] Secondly, this application provides a precast assembled concrete frame and its assembly method, employing the following technical solution: A precast assembled concrete frame and its assembly method include the following steps: S1: Configure the mounting base, prefabricated frame, and guide components according to the required dimensions; S2: Place the fixing seat in the corresponding installation position, with the side of the fixing seat with the limit frame facing upwards, and perform pre-embedding treatment on the fixing seat; S3: Place the two sets of guide components on the upper surface of the fixed seat, so that the positioning seat fits against the upper surface of the fixed seat, and align the two sets of guide components so that the trapezoidal insert is inserted into the corresponding trapezoidal groove. At this time, the two semi-threaded columns are aligned, and the threaded tube is threadedly connected to the two semi-threaded columns to lock and position the two guide components. S4: Use a crane to lift the precast frame, so that the precast frame moves downward from the upper end of the guide member, so that the precast frame enters the guide groove along the side groove and moves towards the fixed seat along the guide groove. The precast frame is in a vertical state when it moves. When the precast frame abuts against the fixed seat, the insertion rod is inserted into the connection hole. At this time, the support column is located in the casting cavity and both the transverse support block and the longitudinal support block abut against the precast frame. After the installation of the precast frame and the fixed seat is completed, the two guide members are removed. S5: Concrete is poured through the pouring hole. The concrete pushes open the sealing plate and enters the pouring cavity along the flow cavity, pouring pipe one and pouring pipe two. Under the action of gravity, it enters the fixed cavity through the connecting cavity. After the pouring cavity is filled with concrete, pouring stops. Under the action of gravity and the concrete in pouring pipe one, the sealing plate rotates toward the pouring hole and seals the pouring hole. S6: After pouring, the pouring hole is sealed and the surface of the precast frame is smoothed. At the same time, the connection between the precast frame and the limiting frame is sealed with sealant to complete the construction.

[0023] In summary, this application includes at least one of the following beneficial technical effects of precast assembled concrete frames and assembly methods: 1. Pre-embed the fixed base in an appropriate position, place the two guide pieces on the upper end of the fixed base so that the positioning base abuts against the upper end face of the fixed base, thereby supporting the guide pieces. Connect the two guide pieces, at this time the two guide grooves are connected, and the limiting frame is located in the receiving groove, and the two semi-threaded columns are mutually attached. The threaded tube is aligned with the two semi-threaded columns. Rotate the rotating block so that the two semi-threaded columns are threadedly connected in the threaded tube. The threaded tube and the rotating block cooperate to limit the two semi-threaded columns, thereby limiting the two guide pieces. The precast frame is hoisted by a crane and inserted into a guide channel formed by two guide grooves. The precast frame is then gradually lowered, and the two guide components work together to limit the precast frame, thereby reducing the probability of tilting or swaying during installation. After the lower end of the precast frame contacts the fixing seat, the insertion rod is inserted into the connection hole, thereby realizing the assembly of the fixing seat and the precast frame. Concrete is poured into the pouring cavity through the pouring hole. After pouring is completed, the pouring hole is sealed, thus completing the construction. The guide components support and guide the precast frame, which helps to reduce the probability of swaying or tilting during installation and improves the installation stability of the precast frame. 2. The support roller and the limiting roller work together to support the guide belt, so that the guide belt rotates around the support roller in the mounting groove. After the prefabricated frame comes into contact with the guide belt, the friction force drives the guide belt to rotate. The guide belt helps to reduce the rigid collision between the prefabricated frame and the guide component, thereby reducing the probability of damage to the prefabricated frame. 3. When pouring concrete into the pouring hole, the concrete flows upward along the first pouring channel. After entering the second pouring channel, it flows towards the lowest outlet under the action of gravity. When the concrete in the pouring cavity submerges the lowest outlet, the concrete fills the lower end of the pouring channel and is discharged from the upper injection port. The concrete gradually spreads from bottom to top, which helps to reduce the probability of voids in the concrete in the pouring cavity. Attached Figure Description

Detailed Implementation

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a prefabricated assembled concrete frame. Example

[0032] Reference Figure 1 and Figure 2 A precast assembled concrete frame includes a fixing base 1, a precast frame 2, and two guide members 3. A limiting frame 11 is provided on the upper surface of the fixing base 1. The fixing base 1 is pre-embedded in an appropriate position, so that the limiting frame 11 is upward-facing. Two sets of guide members 3 are placed on the fixing base 1, so that the two guide members 3 are symmetrically arranged with the limiting frame 11 as the center, and the positioning seat 31 is in contact with the upper surface of the fixing base 1, so that the positioning seat 31 supports the guide members 3.

[0033] Reference Figure 2 and Figure 3The operator manipulates the two guide members 3 to move closer together. The lower end of the positioning seat 31 has a receiving groove 311 that matches the limiting frame 11. When the two guide members 3 are in contact with each other, the limiting frame 11 is located between the two receiving grooves 311, and the limiting frame 11 is in contact with the inner wall of the receiving groove 311, so that the fixing seat 1 limits the guide member 3 through the limiting frame 11. A splicing structure is provided on the side where the two guide members 3 are close to each other. One guide member 3 is fixedly connected with multiple trapezoidal inserts 361 along the vertical direction, and the other guide block has a trapezoidal groove 362 that matches the trapezoidal inserts 361.

[0034] Reference Figure 2 and Figure 3 When the two guide members 3 approach each other, the trapezoidal insert 361 gradually inserts into the corresponding trapezoidal groove 362. The upper end face of the trapezoidal insert 361 is inclined from bottom to top, moving away from the trapezoidal groove 362. The lower end face of the trapezoidal insert 361 is symmetrically arranged with respect to the upper end face. When the trapezoidal insert 361 cooperates with the trapezoidal groove 362, it helps to guide the two guide members 3 and reduces the probability of misalignment between the two guide members 3.

[0035] Reference Figure 1 and Figure 3 Two sets of locking elements 4 are provided between the two guide elements 3. The two sets of locking elements 4 are symmetrically arranged with the guide elements 3 as the center. The locking element 4 includes a threaded tube 42 and a rotating block 41. The rotating block 41 is fixedly connected to one end of the threaded tube 42. Each guide element 3 is fixedly connected with a semi-threaded post 35 corresponding to the locking element 4. The cross-section of the semi-threaded post 35 is a complete semicircle. The semi-threaded post 35 is provided with an arc-shaped surface and a straight surface. The semi-threaded post 35 is provided with external threads along the length direction of the arc-shaped surface.

[0036] Reference Figure 1 and Figure 3 When the two guide members 3 are in contact with each other, the two semi-threaded posts 35 located on the same side are in contact along the straight surface. At this time, the two semi-threaded posts 35 form a complete threaded post. The operator aligns the threaded tube 42 with the threaded post. The threaded tube 42 has internal threads that are compatible with the semi-threaded posts 35. The operator rotates the rotating block 41, so that the rotating block 41 drives the threaded tube 42 to engage with the two semi-threaded posts 35. The threaded tube 42 limits the two semi-threaded posts 35, and in turn, the two semi-threaded posts 35 limit the two guide members 3.

[0037] Reference Figure 2 and Figure 3Each of the two guide members 3 has a guide groove 32 on one side that is close to each other. The guide grooves 32 are evenly arranged vertically, and the bottom surface of the guide grooves 32 is flush with the inner wall of the limiting frame 11. A variable diameter groove 33 is provided at the upper end of the guide member 3. The variable diameter groove 33 is connected to the guide groove 32. The diameter of the variable diameter groove 33 gradually increases from bottom to top, and the minimum diameter of the variable diameter groove 33 is the same as the diameter of the guide groove 32.

[0038] Reference Figure 2 and Figure 3 The guide member 3 has an installation groove 34 along the length of the variable diameter groove 33 and the guide groove 32. Multiple evenly spaced support rollers 341 are installed within the installation groove 34. The support rollers 341 are rotatably connected to the guide member 3 and are evenly spaced vertically. Each support roller 341 within the same installation groove 34 is rotatably connected to a guide belt 343, which is wound around the outside of the support roller 341. A limiting roller 342 is located at the connection between the guide groove 32 and the variable diameter groove 33. The limiting roller 342 is parallel to the support rollers 341 and rotatably connected to the guide member 3. The limiting roller 342 and the guide belt 343 are rolled together on the side away from the support roller 341. Under the support of the limiting roller 342, the guide belt 343 is kept taut, which helps reduce the probability of damage to the guide belt 343 due to friction between the guide belt 343 and the guide member 3.

[0039] Reference Figure 2 and Figure 4 The precast frame 2 is lifted by a crane and moved above the guide member 3. When the two guide members 3 are in contact, the guide grooves 32 on the guide members 3 are interconnected. The two guide grooves 32 cooperate to form a guide channel. The operator operates the crane to lower the precast frame 2, so that the precast frame 2 moves along the variable diameter groove 33 to the guide groove 32. The variable diameter groove 33 helps to improve the convenience of the precast frame 2 entering the guide groove 32 and reduces the probability of the precast frame 2 colliding with the guide member 3.

[0040] Reference Figure 2 and Figure 4 When the precast frame 2 comes into contact with any guide belt 343, it causes the guide belt 343 to rotate towards the fixed seat 1. The guide belt 343 helps to reduce the rigid collision between the precast frame 2 and the guide member 3, thereby reducing the probability of the precast frame 2 being damaged due to collision with the guide member 3 caused by shaking. After the precast frame 2 enters the guide groove 32, the two guide members 3 cooperate to limit the precast frame 2, causing the precast frame 2 to move vertically towards the fixed seat 1, thereby reducing the probability of shaking when the precast frame 2 moves.

[0041] Reference Figure 2 and Figure 4The limiting frame 11 is provided with a plurality of evenly arranged insert rods 12. The insert rods 12 are vertically fixed to the fixed base 1. The precast frame 2 moves toward the insert rods 12 under the drive of the crane. The lower end of the precast frame 2 is provided with connection holes 23 corresponding to the insert rods 12. When the precast frame 2 is inserted into the limiting frame 11, the insert rods 12 are inserted into the corresponding connection holes 23 and the insert rods 12 are in contact with the inner wall of the connection holes 23. The insert rods 12 and the limiting frame 11 cooperate to limit the precast frame 2.

[0042] Reference Figure 2 and Figure 4 A support column 15 is fixed to the upper end of the fixed base 1. The support column 15 is perpendicular to the fixed base 1. A casting cavity 21 is vertically opened inside the precast frame 2. When the precast frame 2 moves towards the fixed base 1, the support column 15 is inserted into the casting cavity 21, and the support column 15 does not contact the inner wall of the casting cavity 21. The casting cavity 21 has a rectangular cross-section. A transverse support block 151 is fixedly connected to the upper end of the support column 15. The transverse support block 151 abuts against the inner wall of the casting cavity 21 along the transverse direction. The upper end of the support column 15 is also provided with a longitudinal support block 152 that is perpendicular to the transverse support block 151. The longitudinal support block 152 abuts against the inner wall of the casting cavity 21 along the longitudinal direction.

[0043] Reference Figure 1 and Figure 4 The fixed base 1 positions the support column 15, which in turn supports the precast frame 2 through the transverse support block 151 and the longitudinal support block 152, thereby improving the connection strength between the fixed base 1 and the precast frame 2. After the fixed base 1 and the precast frame 2 are installed, the operator rotates the rotating block 41 of the two locking parts 4 in the opposite direction, thereby releasing the threaded engagement between the threaded pipe 42 and the two semi-threaded columns 35. At this time, the positioning between the two guide parts 3 is released, making it easy for the operator to remove the two guide parts 3 from the fixed base 1.

[0044] Reference Figure 4 and Figure 5 A pouring hole 22 is opened on either side of the precast frame 2, and a pouring pipe 221 is opened vertically along the precast frame 2. The lower end of the pouring pipe 221 is connected to the pouring hole 22. The operator pours concrete into the pouring channel through the pouring hole 22. The precast frame 2 has a flow cavity 224. The diameter of the flow cavity 224 is larger than the diameter of the pouring hole 22 and the diameter of the pouring channel. The flow cavity 224 is located at the connection between the pouring hole 22 and the pouring channel. The concrete flows from the pouring hole 22 into the flow cavity 224.

[0045] Reference Figure 4 and Figure 5A sealing plate 225 is provided inside the flow cavity 224. The upper end of the sealing plate 225 is hinged to the precast frame 2. When the concrete flows, it pushes the sealing plate 225 open and enters the flow cavity 224, flowing along the flow cavity 224 towards the first pouring channel. The precast frame 2 also has a second pouring pipe 222, which is parallel to the first pouring pipe 221. The upper end of the first pouring pipe 221 is connected to the upper end of the second pouring pipe 222. The concrete flows upward along the first pouring channel and enters the second pouring channel.

[0046] Reference Figure 4 and Figure 5 The second pouring pipe 222 has multiple evenly spaced discharge ports 223 vertically arranged on the side near the pouring chamber 21. After entering the second pouring pipe, the concrete flows downward under the action of gravity. The concrete enters the pouring chamber 21 from the lowest discharge port 223 and flows towards the fixed seat 1. The fixed seat 1 has a fixed cavity 14, and the fixed seat 1 also has a connecting cavity 13 that communicates with the fixed cavity 14. The diameter of the connecting cavity 13 is smaller than the diameter of the fixed cavity 14, and the connecting cavity 13 communicates with the pouring chamber 21. The concrete enters the fixed cavity 14 along the connecting cavity 13, and gradually fills the fixed cavity 14.

[0047] Reference Figure 4 and Figure 5 After the concrete fills the fixed cavity 14 and the connecting cavity 13, it gradually spreads upwards and covers the discharge port 223 at the bottom. At this time, the concrete accumulates at the lower end of the second pouring pipe 222. After the concrete in the second pouring pipe 222 is full, it continues to be discharged into the pouring cavity 21 from the upper discharge port 223, thus continuing to fill the pouring cavity 21. The concrete in the pouring cavity 21 spreads in sections from bottom to top, which facilitates the discharge of air in the pouring cavity 21 through the concrete and reduces the probability of concrete splashing in the pouring cavity 21.

[0048] Reference Figure 4 and Figure 5 After the second pouring pipe 222 is completed, the operator stops supplying concrete to the pouring hole 22. At this time, the sealing plate 225 tends to flip downwards under the influence of gravity. Simultaneously, the concrete in the first pouring pipe comes into contact with the upper surface of the sealing plate 225, thus pushing the sealing plate 225 to rotate towards the pouring hole 22. After the sealing plate 225 comes into contact with the precast frame 2, it seals the pouring hole 22, thereby reducing the probability of concrete leakage from the first pouring hole 221, and thus completing the pouring. After the concrete solidifies, the precast frame 2 and the fixing seat 1 are assembled.

[0049] Reference Figure 4 and Figure 5After the concrete in the connecting cavity 13 and the fixing cavity 14 solidifies, the concrete blocks in the fixing cavity 14 and the concrete blocks in the connecting cavity 13 cooperate with each other, which helps to improve the connection strength between the fixing seat 1 and the precast frame 2. When installing the precast frame 2, the guide 3 is used to position and guide the precast frame 2, which helps to reduce the probability that the precast frame 2 will shake during hoisting, causing the precast frame 2 to collide with the insertion rod 12 and bend the insertion rod 12. This helps to improve the installation stability of the precast frame 2 and reduce the probability of the precast frame 2 tilting after installation.

[0050] The implementation principle of a precast assembled concrete frame according to an embodiment of this application is as follows: A fixed base 1 is pre-embedded to position the fixed base 1. Two guide members 3 are installed on the upper end of the fixed base 1 and locked in place by locking members 4, so that the rectangular frame is located between two receiving grooves 311. The fixed base 1 supports and limits the guide members 3 through the limiting frame 11. A crane is used to move the precast frame 2 along the variable diameter groove 33 towards the guide groove 32. When the precast frame 2 is in contact with the guide belt 343, the guide belt 343 rotates under the support of the support roller 341 and the limiting roller 342. After the precast frame 2 enters the guide groove 32, the two guide members 3 cooperate to limit the precast frame 2, causing the precast frame 2 to move vertically, thereby reducing the probability of the precast frame 2 swaying. After the precast frame 2 enters the limiting frame 11, the insertion rod 12 is gradually inserted into the connecting hole 23 and fits against the inner wall of the connecting hole 23. The insertion rod 12 cooperates with the inner wall of the connecting hole 23 to limit the prefabricated frame 2. At the same time, the limiting column supports the prefabricated frame 2 through the transverse support block 151 and the longitudinal support block 152, thereby improving the installation stability of the prefabricated frame 2. When installing the prefabricated frame 2, the prefabricated frame 2 is not easy to tilt, which helps to improve the installation stability of the prefabricated frame 2.

[0051] This application also discloses a method for assembling a precast assembled concrete frame, which adopts the following technical solution: A method for assembling a precast assembled concrete frame includes the following steps. S1: Configure the fixing seat 1, prefabricated frame 2 and guide component 3 according to the required dimensions; S2: Place the fixing seat 1 in the corresponding installation position, so that the side of the fixing seat 1 with the limiting frame 11 is facing upward, and perform pre-embedding treatment on the fixing seat 1; S3: Place the two sets of guide pieces 3 on the upper surface of the fixed seat 1, so that the positioning seat 31 fits against the upper surface of the fixed seat 1, and connect the two sets of guide pieces 3 so that the trapezoidal insert 361 is inserted into the corresponding trapezoidal groove 362. At this time, the two semi-threaded columns 35 are connected, and the threaded tube 42 is threadedly connected to the two semi-threaded columns 35 to lock and position the two guide pieces 3. S4: Use a crane to lift the precast frame 2, so that the precast frame 2 moves downward from the upper end of the guide member 3, so that the precast frame 2 enters the guide groove 32 along the side groove, and moves towards the fixed seat 1 along the guide groove 32. The precast frame 2 is in a vertical state when it moves. When the precast frame 2 abuts against the fixed seat 1, the insertion rod 12 is inserted into the connection hole 23. At this time, the support column 15 is located in the pouring cavity 21 and the transverse support block 151 and the longitudinal support block 152 abut against the precast frame 2. After the installation of the precast frame 2 and the fixed seat 1 is completed, the two guide members 3 are removed. S5: Concrete is poured through the pouring hole 22. The concrete pushes open the sealing plate 225 and enters the pouring cavity 21 along the flow cavity 224, pouring pipe one 221 and pouring pipe two 222. Under the action of gravity, the concrete enters the fixed cavity 14 through the connecting cavity 13. After the pouring cavity 21 is filled with concrete, pouring is stopped. Under the action of gravity and the concrete in the pouring pipe one 221, the sealing plate 225 rotates toward the pouring hole 22 and seals the pouring hole 22. S6: After the pouring is completed, the pouring hole 22 is sealed and the surface of the precast frame 2 is smoothed. At the same time, the connection between the precast frame 2 and the limiting frame 11 is sealed with sealing material to complete the construction.
