Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fabricated building, specifically a prefabricated house convenient for quick assembly. BACKGROUND

[0002] The fabricated house is assembled by transporting the building wallboard to the construction site after the building material is processed in the factory. This construction method greatly shortens the construction period, reduces the on-site construction time and labor cost.

[0003] During the hoisting and positioning of the prefabricated wallboard, the worker needs to check whether the lower opening sleeve of the wallboard and the connecting steel bar are aligned by using a small mirror. If they are not aligned, repeated checking and adjustment are needed, which is complicated. In the process of manual alignment, there may be problems such as insufficient manpower and time-consuming operation.

[0004] Therefore, how to quickly align and install the steel bar into the sleeve is a problem to be solved. UTILITY MODEL CONTENTS

[0005] The utility model discloses a prefabricated house convenient for quick assembly, which is characterized in that an installation auxiliary part is arranged between the wallboard and the bottom plate, the bottom of the auxiliary part is provided with a horn-shaped guide inlet, and the top of the auxiliary part is a guide outlet. The guide inlet is directly opposite to the steel bar, and the guide outlet is aligned with the embedded sleeve. In the process of installing the wallboard, the steel bar is quickly aligned and installed into the sleeve by using the horn-shaped opening of the auxiliary part, thereby overcoming the problem that the sleeve and the connecting steel bar are not well aligned in the prior art.

[0006] The prefabricated house in the prior art is assembled by prefabricated plates. Before assembling the wallboard, the construction quality inspection personnel inspects whether the position and perpendicularity of the reserved steel bar meet the requirements according to the wallboard drawing. Then, the wallboard is hoisted. After the wallboard is close to the top of the reserved steel bar, the wallboard is slowly lowered by manual holding. During the falling process, a mirror is placed near the reserved steel bar to observe and adjust, so that the grouting sleeve and the vertical steel bar are aligned. However, the above operation is time-consuming and laborious.

[0007] The utility model mainly realizes the purpose through the following technical scheme:

[0008] A prefabricated house convenient for quick assembly, which comprises a wallboard and a bottom plate, the bottom of the wallboard is provided with an embedded sleeve A, the bottom plate is provided with a steel bar, the embedded sleeve A on the wallboard can be inserted with the steel bar on the bottom plate, and further comprises an auxiliary part, the bottom of the auxiliary part is provided with a horn-shaped guide inlet, the top of the auxiliary part is a guide outlet, the guide inlet is directly opposite to the steel bar, and the guide outlet is aligned with the embedded sleeve A; the steel bar can enter from the guide inlet, pass through the guide outlet, and be inserted into the embedded sleeve A.

[0009] There is only one passage between the inlet and the outlet.

[0010] The prefabricated house in the prior art is assembled by prefabricated boards, and before assembling the wall boards, a construction quality inspection personnel inspects whether the position and verticality of the reserved steel bars meet the requirements according to the wall board drawings, and then hoists the wall boards, and after the wall boards are close to the top of the reserved steel bars, the wall boards are slowly lowered by manual holding, and a mirror is placed near the reserved steel bars during the falling process to observe and adjust, so that the embedded sleeve A and the vertical steel bars are aligned, but the above operation is time-consuming and laborious.

[0011] The utility model sets up an auxiliary part, the auxiliary part is equipped with the guide inlet of loudspeaker type, compared with the caliber of embedded sleeve A, the loudspeaker opening area of guide inlet increases, and it is convenient for embedding embedded sleeve A into the steel bar. After entering the guide inlet, the movable area of the steel bar is gradually constrained, and the longitudinal alignment degree of the steel bar and the embedded sleeve A is further improved.

[0012] The outlet is inserted into the embedded sleeve A, and after the steel bar enters the auxiliary part, it is out through the outlet and then enters the embedded sleeve A, and the outlet structure is simple and practical.

[0013] Because there is only one passage for guiding the steel bar into the embedded sleeve A in the auxiliary part, and the top of the auxiliary part can be inserted into the embedded sleeve A, after the steel bar enters the guide inlet, it can only enter the embedded sleeve A from the outlet along the passage. Therefore, even if the position of the steel bar and the inlet of the embedded sleeve A is not completely aligned at the beginning, it can be guided through the loudspeaker-shaped guide inlet. Compared with the prior art, the steel bar can only be completely aligned with the barrel of the embedded sleeve A to be successfully installed, and the utility model is simple to operate and can realize the rapid alignment and installation of the wall board.

[0014] Further, the bottom of the wall board is a steel structure, and the steel structure and the wall board are embedded with each other to form a vertical whole board.

[0015] The auxiliary part longitudinally penetrates the steel structure and is fixedly connected on the steel structure.

[0016] The outlet extends upwardly out of the steel structure.

[0017] The bottom of the steel structure is provided with a cavity, and the cavity can completely accommodate the guide inlet.

[0018] A steel structure is arranged at the bottom of the wall board, and the auxiliary part is arranged on the steel structure, so that the wall board, the steel structure and the auxiliary part are integrated, and the time cost of on-site matching and installation is reduced.

[0019] The steel structure and the wall board are embedded with each other to form a vertical whole board: that is, the steel structure and the wall board can be embedded with each other to form a flat and regular wall board, so that the contact surfaces of the two are in full contact, and the surface of the installed wall board is flat, and the overall structure is more stable after installation.

[0020] The steel structure is provided with a cavity capable of accommodating the guide inlet, so that after the wallboard is installed, the guide inlet can be accommodated in the cavity of the steel structure, the temporary disassembly of the auxiliary part can be avoided, and the stability of the connection between the wallboard, the steel structure and the bottom plate and the subsequent use is not affected without disassembling the auxiliary part.

[0021] Further, the auxiliary part comprises a circular tube, and an inner diameter of the circular tube is greater than a diameter of the reinforcing bar.

[0022] A top of the circular tube is the guide outlet, and the guide outlet is a variable cross-section tube body with a gradually increasing radius from top to bottom, and an outer diameter of the variable cross-section tube body is less than a diameter of the embedded sleeve A.

[0023] In the embodiment, the auxiliary part comprises a circular tube, and an inside of the circular tube is the only passageway between the guide inlet and the guide outlet.

[0024] The guide outlet at the top of the auxiliary part is a variable cross-section tube body, so that a size of the top of the guide outlet can be reduced, and the head of the guide outlet can be more conveniently inserted into a barrel mouth of the embedded sleeve A.

[0025] Further, a plurality of sleeve rings are sleeved on the circular tube, the sleeve rings are rotationally connected with the circular tube, an outer wall of each sleeve ring is hingedly connected with a sector, and a plurality of sectors can be uniformly distributed around the circular tube as a horn shape with an opening downward.

[0026] An inside of the sleeve ring is provided with an expansion block, the circular tube is provided with an opening and a movable rod, the movable rod can move in a direction perpendicular to an axis of the circular tube in the opening, the expansion block can radially extend into the opening and abut against the movable rod to make the movable rod partially extend into the inside of the circular tube, and the reinforcing bar can extrude the movable rod to the sleeve ring to push the expansion block to be separated from the opening.

[0027] Because the thickness of the wallboard is limited, if the guide inlet is completely located in the wallboard, the size of the guide inlet is limited, and the change is not large compared with the area of the embedded sleeve A in actual use, and a mirror or the like is still needed to observe in use.

[0028] The horn guide inlet in the embodiment is enclosed by a plurality of sectors, and the sectors are connected with the circular tube through the internally provided sleeve ring, so that the sectors will not easily separate from the tube, and the structural reliability of the guide inlet in use is ensured.

[0029] The collar is rotatably connected to the circular tube, and the telescopic block can partially extend into the opening of the circular tube in its natural state, preventing the collar and the circular tube from rotating relative to each other. This stabilizes the trumpet-shaped structure formed by the multiple segments. When the rebar is inserted into the circular tube and compresses the movable rod, the movable rod moves radially outward, pushing the telescopic block out of the opening. Once the telescopic block retracts outside the circular tube, the positional constraint between the collar and the circular tube is released. Because the collar is rotatably connected to the circular tube, the multiple segments can be rotated or moved upward to align and fit within the cavity of the wallboard. In this embodiment, the inlet opening can extend beyond the bottom of the wallboard during initial use, maximizing the area of ​​the inlet opening and facilitating the entry of the rebar. Later, as the rebar enters the circular tube and maintains longitudinal alignment with the embedded sleeve A, the segments are rotated until the multiple segments are aligned vertically, retracting the inlet opening into the cavity. This eliminates the need to affect contact between the steel structure and the baseplate, ensuring the stability of the overall structure.

[0030] The fan-shaped piece is hinged to the collar, so the fan-shaped piece can rotate longitudinally relative to the collar. When the steel structure and the wall panel are pressed downward, the fan-shaped piece will rotate upward under pressure after contacting the bottom plate, and will eventually be pressed into the cavity. This can reduce the longitudinal spatial height of the fan-shaped piece, thereby reducing the height of the cavity and ensuring the integrity and pressure-bearing capacity of the steel structure as much as possible.

[0031] Furthermore, there are a plurality of wall panels, and two adjacent wall panels are connected to each other to form a contact surface, and the joint of the contact surface is set as a "V"-shaped joint.

[0032] Since the connection surface of two adjacent wall panels inevitably has a seam, there is a risk of rain leakage. In this embodiment, the outer side of the contact surface of the two adjacent wall panels is V-shaped, which is convenient for applying glue at the V-shaped opening later, thereby achieving the effect of filling the cracks and preventing water seepage.

[0033] The joints that need to be waterproofed are arranged on the outside of the contact surface. Compared with specializing the contact surface, this embodiment has a simple structure and is convenient for subsequent processing.

[0034] Furthermore, an embedded sleeve B and a perforation are provided on the outer surface of the wall panel. The position of the embedded sleeve B on one wall panel corresponds to the position of the perforation on an adjacent wall panel. A bolt B is provided between the perforation and the embedded sleeve B, and the perforation and the embedded sleeve B are connected through the bolt B.

[0035] In order to enhance the stability and reliability of the connection between prefabricated panels, this embodiment provides through-holes and embedded sleeves B on the prefabricated panels, and inserts bolts B through the through-holes and into the embedded sleeves B to connect the two wall panels.

[0036] Furthermore, it also includes a top plate, and a hanging part is arranged above the top plate.

[0037] In order to facilitate hoisting of the top plate, a hoisting piece is arranged above the top plate for lifting installation.

[0038] Further, the top of the wall plate is provided with a pre-buried sleeve C, and the top plate is provided with a connecting hole;

[0039] The hoisting piece comprises a hoisting tool, the hoisting tool can cover the pre-buried sleeves C at the top of any two adjacent wall plates, and the hoisting tool is provided with a bolt C, the bolt C passes through the hoisting tool and the connecting hole downwards in sequence and is connected with the pre-buried sleeve C;

[0040] A universal lifting ring is arranged at the top of the hoisting tool.

[0041] Covering two connecting points with one hoisting tool can simplify the installation process, make the stress more concentrated, and be beneficial to reducing the structural instability problem caused by dispersed stress.

[0042] Further, the outside of the bolt C in the two adjacent wall plates is wrapped with a support pipe, and the two support pipes are located between the hoisting tool and the top plate, and a connecting rod is arranged between the two support pipes.

[0043] The support pipe is wrapped outside the bolt C, so that the cross-sectional area of the support pipe is large enough to increase the contact area between the support pipe and the hoisting tool and the top plate, and the force transmission effect is increased. Meanwhile, the support pipe is located between the hoisting tool and the top plate, so that the force transmission is strengthened.

[0044] A connecting rod is arranged between the two connecting pipes to transmit the force from the bolts C on both sides to the middle part.

[0045] The screw rod of the universal lifting ring passes through the connecting rod downwards and is connected with the screw rod of the universal lifting ring and the connecting rod, and the connection mode is simple and convenient.

[0046] Compared with the prior art, the utility model has the following beneficial effects:

[0060] Embodiment:

[0061] In the prior art, when installing the wall panel 2, in order to ensure that the embedded sleeve A below the prefabricated wall panel 2 is accurately aligned with the connecting steel bar 7 and to ensure the stability and safety of the structure, it is often necessary to manually align the embedded sleeve A below the wall panel 2 with the connecting steel bar 7 using a small mirror. This method relies on manual observation and judgment, which may be affected by factors such as line of sight and light, and there is a certain risk of error. The operation process is cumbersome and inefficient. In order to solve the problem of difficult and inefficient manual position adjustment in the prior art, the present application uses a trumpet-shaped auxiliary component 6 to quickly align the steel bar 7 and install it into the sleeve, thereby overcoming the problem of poor alignment between the sleeve and the connecting steel bar 7 in the prior art.

[0062] like Figures 1-8 As shown, a prefabricated house that is easy to assemble quickly includes a wall panel 2 and a bottom plate 4. The bottom of the wall panel 2 is provided with an embedded sleeve A, and the bottom plate 4 is provided with a steel bar 7. The embedded sleeve A on the wall panel 2 can be plugged into the steel bar 7 on the bottom plate 4. The auxiliary member 6 also includes an auxiliary member 6. The bottom of the auxiliary member 6 is provided with a trumpet-shaped introduction port, and the top of the auxiliary member 6 is an outlet port. The introduction port is directly opposite to the steel bar 7, and the outlet port is aligned with the embedded sleeve A. The steel bar 7 can enter from the introduction port, pass through the outlet port, and pass into the embedded sleeve A.

[0063] There is a unique passage between the inlet and the outlet.

[0064] The prefabricated house in the prior art is assembled from prefabricated panels. Before assembling the wall panel 2, the construction quality inspector checks whether the position and verticality of the reserved steel bars 7 meet the requirements based on the wall panel 2 drawings. Then the wall panel 2 is hoisted. After the wall panel 2 is close to the top of the reserved steel bars 7, it is slowly lowered by hand. During the falling process, a mirror is placed near the reserved steel bars 7 for observation and adjustment, so that the embedded sleeve A and the vertical steel bars 7 are aligned. However, the above operation is time-consuming and labor-intensive.

[0065] The present invention provides an auxiliary member 6 with a trumpet-shaped inlet. Compared to the diameter of the embedded sleeve A, the trumpet-shaped opening area of ​​the inlet is larger, making it easier to insert the embedded sleeve A into the rebar 7. After entering the inlet, the movable area of ​​the rebar 7 is gradually restricted, further improving the longitudinal alignment between the rebar 7 and the embedded sleeve A.

[0066] The guide port is inserted into the embedded sleeve A. After the steel bar enters the auxiliary component, it passes through the guide port and enters the embedded sleeve A. The guide port has a simple and practical structure.

[0067] Since only one passageway for guiding the steel bar into the pre-buried sleeve A exists in the auxiliary member 6, and the top of the auxiliary member 6 can penetrate into the pre-buried sleeve A, after the steel bar 7 enters the guide inlet, the steel bar 7 can only enter the pre-buried sleeve A from the guide outlet along the passageway. Therefore, even if the position of the steel bar 7 and the inlet of the pre-buried sleeve A is not completely aligned at the beginning, the steel bar 7 can be guided through the trumpet-shaped guide inlet. Compared with the prior art, the steel bar 7 can only be successfully installed when the steel bar 7 is completely aligned with the barrel mouth of the pre-buried sleeve A. The utility model has the advantages of simple operation and can realize the rapid alignment and installation of the wallboard 2.

[0068] As an implementable manner of the above-mentioned scheme, the auxiliary member 6 is a pipe with a platform shape, the size of the pipe mouth at the bottom of the pipe is larger than the size of the pipe mouth at the top of the pipe, and the top of the pipe can be directly connected to the barrel mouth of the pre-buried sleeve A. In use, the top of the pipe can be connected to the barrel mouth of the pre-buried sleeve A, and then the wallboard 2 is lowered to make the pipe mouth at the bottom of the pipe can be sleeved on the steel bar 7. Since the size of the pipe mouth at the bottom of the pipe is larger than the size of the barrel mouth of the pre-buried sleeve A, the steel bar 7 can be quickly inserted into the pre-buried sleeve A.

[0069] As an implementable manner of the above-mentioned scheme, the auxiliary member 6 is detachably connected by two parts, so that the height of the auxiliary member 6 is lower than the height of the steel bar 7. When the top of the steel bar 7 is inserted into the barrel mouth of the pre-buried sleeve A, the auxiliary member 6 is detached and removed.

[0070] Further, the bottom of the wallboard 2 is a steel structure 3, and the steel structure 3 and the wallboard 2 are embedded with each other to form a vertical whole plate.

[0071] The auxiliary member 6 longitudinally penetrates the steel structure 3 and is fixedly connected to the steel structure 3.

[0072] The guide outlet extends upwardly beyond the steel structure 3.

[0073] The bottom of the steel structure 3 is provided with a cavity, and the cavity can completely accommodate the guide inlet.

[0074] A steel structure 3 is arranged at the bottom of the wallboard 2, and the auxiliary member 6 is arranged on the steel structure 3, so that the wallboard 2, the steel structure 3 and the auxiliary member 6 are integrated, thereby reducing the time cost of on-site matching and installation.

[0075] The steel structure 3 and the wallboard 2 are embedded with each other to form a vertical whole plate: that is, the steel structure 3 and the wallboard 2 can be embedded with each other to form a flat and regular wallboard, so that the contact surfaces of the two are in full contact, and the surface of the installed wallboard 2 is flat, and the overall structure is more stable after installation.

[0076] The steel structure 3 is provided with a cavity capable of accommodating the guide inlet, so that after the wallboard 2 is installed, the guide inlet can be accommodated in the cavity of the steel structure 3, the temporary disassembly of the auxiliary part 6 can be avoided, and the stability of the connection between the wallboard 2, the steel structure 3 and the bottom plate 4 and the subsequent use is not affected without dismounting the auxiliary part 6.

[0077] As an implementable manner of the above scheme, the wallboard 2 is provided with an insertion port at a position close to the side edge of the bottom, the height of the steel structure 3 is greater than or equal to the height of the horn-shaped guide inlet, the thickness and length of the steel structure 3 are the same as the thickness and length of the bottom surface of the wallboard 2, and the two ends of the steel structure 3 are provided with vertical insertion parts, and the steel structure 3 and the wallboard 2 can be embedded with each other.

[0078] As a specific implementation of the above implementable manner, the upper surface of the steel structure 3 is completely attached to and fixedly connected with the bottom surface of the wallboard 2.

[0079] As an implementable manner of the above scheme, the bottom of the guide inlet is flush with the bottom surface of the steel structure 3, which is convenient for production and transportation.

[0080] Further, the auxiliary part 6 includes a circular tube 604, and the inner diameter of the circular tube 604 is greater than the diameter of the reinforcing bar 7.

[0081] The top of the circular tube 604 is the guide outlet, and the guide outlet is a variable cross-section pipe body with a gradually increasing radius from top to bottom, and the outer diameter of the variable cross-section pipe body is smaller than the diameter of the embedded sleeve A.

[0082] In the embodiment, the auxiliary part 6 includes a circular tube 604, and the inside of the circular tube 604 is the only passage between the guide inlet and the guide outlet.

[0083] The guide outlet at the top of the auxiliary part 6 is a variable cross-section pipe body, so that the size of the top of the guide outlet can be reduced, and the head of the guide outlet can be more conveniently inserted into the barrel of the embedded sleeve A.

[0084] Further, a plurality of sleeve rings 602 are sleeved on the circular tube 604, the sleeve rings 602 are rotationally connected with the circular tube 604, the outer wall of each sleeve ring 602 is hingedly connected with a sector-shaped piece 601, and a plurality of sector-shaped pieces 601 can be circumferentially and uniformly distributed as an open downward horn.

[0085] The inner part of the collar 602 is provided with a telescopic block 603, the circular tube 604 is provided with an opening 605 and a movable rod, the movable rod can move in the direction perpendicular to the axis of the circular tube 604, the telescopic block 603 can radially extend into the opening 605 and abut against the movable rod to make the movable rod partially extend into the inner part of the circular tube 604, the reinforcing steel bar 7 can extrude the movable rod to the direction of the collar 602 to push the telescopic block 603 to be separated from the opening 605.

[0086] Due to the limited thickness of the wallboard 2, if the guide inlet is completely located in the wallboard 2, the size of the guide inlet is limited, and the change is not large compared with the area of the embedded sleeve A in actual use, and a mirror or the like is still needed to observe in use.

[0087] The horn guide inlet in the embodiment is surrounded by a plurality of fan-shaped pieces 601, the fan-shaped pieces 601 are connected with the circular tube 604 through the collar 602 arranged in the inner part, so that the fan-shaped pieces 601 cannot easily separate from the tube, and the reliability of the structure of the guide inlet in use is ensured.

[0088] The collar 602 is rotationally connected with the circular tube 604, and the telescopic block 603 can partially extend into the opening 605 of the circular tube 604 in a natural state, so that the collar 602 and the circular tube 604 cannot rotate relative to each other, thereby stabilizing the horn-shaped structure formed by the plurality of fan-shaped pieces 601. After the reinforcing steel bar 7 is inserted into the circular tube 604 and extrudes the movable rod, the movable rod moves radially outward to push the telescopic block 603 to exit the opening 605, and then the telescopic block 603 is retracted to the outside of the circular tube 604, the position limitation between the collar 602 and the circular tube 604 can be released. Since the collar 602 is rotationally connected with the circular tube 604, the plurality of fan-shaped pieces 601 can be rotated to be located on the same straight line and be accommodated in the cavity of the wallboard 2 by rotating the fan-shaped pieces 601 or moving the fan-shaped pieces 601 upward. The guide inlet of the embodiment can be extended from the bottom of the wallboard 2 in the initial stage of use, and the area of the guide inlet is as large as possible to facilitate the reinforcing steel bar 7 to enter. In the later stage, after the reinforcing steel bar 7 is inserted into the circular tube 604 and tends to be vertically aligned with the embedded sleeve A, the fan-shaped pieces 601 are rotated to be located in the same vertical plane, and the guide inlet is accommodated in the cavity, so that the contact between the steel structure 3 and the bottom plate 4 is not affected, and the stability of the overall structure is ensured.

[0089] The fan-shaped pieces 601 are hinged with the collar 602, so that the fan-shaped pieces 601 can rotate longitudinally relative to the collar 602. In the process of pressing the steel structure 3 and the wallboard 2 downward, the fan-shaped pieces 601 are pressed upward after contacting the bottom plate 4 and are finally pressed into the cavity, so that the longitudinal space height of the fan-shaped pieces 601 is reduced, thereby reducing the height of the cavity and ensuring the integrity and pressure bearing capacity of the steel structure 3 as much as possible.

[0090] As an implementable manner of the above scheme, the sector 601 is arranged on the opposite side of the collar 602. Compared with arranging only one sector 601 on one collar 602, the embodiment can further reduce the height of the superimposed collar 602, so that the cavity height of the steel structure 3 is smaller, the thickness of the steel structure 3 is smaller, or the thickness of the entity above the cavity is higher, thereby improving the stability of the overall structure after installation.

[0091] As an implementable manner of the above scheme, the lower bottom surface of the telescopic block 603 is a slope. When the wallboard 2 is placed downward, the reinforcing steel bar 7 gradually penetrates into the circular tube 604, and the telescopic block 603 is compressed to retract to the outside of the circular tube 604.

[0092] As an alternative of the implementable manner, the part of the telescopic block 603 close to the axis of the circular tube 604 is spherical.

[0093] In the implementation of the above scheme, the opening 605 of the collar 602 corresponding to the position of the telescopic block 603 is an empty shell with the opening 605 facing the axis of the collar 602. The end of the telescopic block 603 away from the axis of the circular tube 604 is connected with a spring, and the other end of the spring is connected to the inner wall of the empty shell of the collar 602. In the natural state of the spring, the telescopic block 603 extends from the opening 605 of the collar 602 into the inside of the circular tube 604, and retracts after being compressed.

[0094] Further, the wallboard 2 has a plurality of wallboards 2, and the contact surfaces of the adjacent two wallboards 2 are connected and form a joint. The joint of the contact surface is a V-shaped joint.

[0095] In the embodiment, the wallboard 2 includes four wallboards 2 in front, back, left and right. The front wallboard 2 has door and window holes. The left and right wallboards 2 both have window holes. The back wallboard 2 is an integral plate. Each wallboard 2 is provided with a space for wire pipe and wire box.

[0096] Because the joint of the contact surface of the adjacent two wallboards 2 cannot be avoided, there is a risk of rain leakage. The embodiment makes the outer side of the contact surface of the adjacent two wallboards 2 V-shaped, which is convenient for later glueing at the V-shaped opening 605, thereby realizing the functions of compensating the crack and preventing water seepage.

[0097] Arranging the joint requiring subsequent waterproof treatment on the outer side of the contact surface is simpler in structure compared with specializing the contact surface. At the same time, it is convenient for later processing.

[0098] Further, the outer side of the wallboard 2 is provided with a pre-buried sleeve B and a perforation. The position of the pre-buried sleeve B on one wallboard 2 corresponds to the position of the perforation on the adjacent wallboard 2. A bolt B is arranged between the perforation and the pre-buried sleeve B, and the perforation and the pre-buried sleeve B are connected through the bolt B.

[0099] In order to enhance the stability and reliability of the connection between the prefabricated plates, the embodiment is provided with through holes and embedded sleeves B on the prefabricated plates, and the bolts B are inserted into the embedded sleeves B through the through holes, so as to connect two wall plates.

[0100] In the above scheme, the embedded sleeve B can be an SGM-85 grouting sleeve, and after the bolt B is inserted, cement slurry is poured to seal and strengthen the connection, thereby improving the stability of the whole house.

[0101] Furthermore, the top plate 1 is further provided with a lifting part 5.

[0102] In order to facilitate the lifting of the top plate 1, the lifting part 5 is arranged above the top plate 1 for lifting installation.
