Description

Technical Field

[0001] The invention relates to the technical field of assembled walls, in particular to a prefabricated wall panel, a wall panel system and a construction method thereof. Background Art

[0002] A sound-absorbing assembled wall panel with publication number "CN111980207A" (classification number: E04B2 / 00) in the prior art relates to the technical field of wall panel installation. The device comprises a mounting base, a first wall panel, a second wall panel and a supporting frame plate. The mounting base, the first wall panel, the second wall panel and the supporting frame plate are all plate structures. The interior of the mounting base is a "concave" trough structure. A positioning block is arranged inside the mounting base. The bottom surfaces of the first wall panel and the second wall panel are both provided with positioning grooves. The positioning block is installed in the positioning groove. A side surface of the first wall panel is provided with a plurality of sliding blocks, and a side surface of the second wall panel is provided with a plurality of sliding grooves. A sound-absorbing box is fixedly installed on one surface of the first wall panel and the second wall panel. The above device facilitates the installation of the wall panel by arranging the mounting base; facilitates the support and fixation of the wall panel by arranging the supporting frame plate; facilitates the positioning and installation of the two wall panels by arranging the positioning block and the positioning groove; and facilitates the sound absorption of the wall panel by arranging the sound-absorbing box.

[0003] However, the above-mentioned sound-absorbing prefabricated wall panels still have obvious defects during use: 1. The existing technology and the above-mentioned prefabricated wall panel structures mostly need to be supported and fixed by inclined supports after installation, so as to prevent the wall from tilting during the later pouring or steel bar bundling process. Since a large number of prefabricated wall panels need to be installed at the same time in prefabricated buildings, a large number of matching inclined supports are required to fix the prefabricated wall panels after installation. A large number of inclined support structures hinder the movement of people and objects in the construction space, and a large number of inclined supports need to be installed and disassembled during and after the installation of the prefabricated wall panels, which is not conducive to improving construction efficiency; 2. The existing prefabricated wall structures usually need to be grouted with a large amount of concrete inside during the installation process to ensure that the prefabricated wall panels are firmly combined with the ground, but the use of concrete grouting will make subsequent disassembly difficult, which is not conducive to the repeated use of prefabricated walls. Summary of the invention

[0004] The object of the present invention is to provide a prefabricated wall panel, a wall panel system and a construction method thereof to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A prefabricated wall panel, comprising a split base and a split wall, wherein the split base comprises a pedestal, wherein the pedestal is a double-layer rectangular parallelepiped stacking structure with the bottom surface of the upper layer inwardly reduced in proportion, wherein a pair of matching steel plates are fixedly mounted on the pedestal, and a pair of anti-tilt columns are fixedly mounted between the matching steel plates, wherein the anti-tilt columns on both sides are fixedly connected to the pedestal, and an assembly groove for the matching steel plates and the anti-tilt columns to enter is provided at the bottom of the split wall;

[0007] A straightening extrusion plate is arranged inside the assembly groove of the split wall on both sides of the anti-tilt column, and the straightening extrusion plates on both sides are threadedly connected with the reverse screw rod through the threaded holes, and an adjustment knob is installed at one end of the reverse screw rod, and the adjustment knob is arranged in the knob hole opened on the side of the split wall. The rotation of the reverse screw rod drives the straightening extrusion plates on both sides to move toward each other, thereby limiting the left and right shaking of the split wall;

[0008] A structural adhesive storage compartment is also provided on the top of the anti-tilt column, and an extrusion push plate is slidably arranged in the structural adhesive storage compartment. The extrusion push plate is extended to the outside of the anti-tilt column through a connecting rod and is fixedly connected to the push plate. The push plate movably abuts against a straightening extrusion plate on one side. The structural adhesive storage compartment is connected with a pair of adhesive injection grooves provided on the outer edge of the base through a pump injection groove provided at the lower part of the anti-tilt column, and the adhesive injection groove provided on the outer edge of the base abuts against a sealing groove provided on the split wall.

[0009] Preferably, a bolt hole is provided on the split base, and the bolt hole is connected with a bolt column arranged on the ground, and the bolt column fixes the split base to the ground by cooperating with a fastening bolt.

[0010] Preferably, a plurality of bolt fastening holes are opened on one side of the split wall, and a plurality of bolt sleeves are installed one-to-one on the side of the split wall away from the plurality of bolt fastening holes. Matching holes corresponding one-to-one to the bolt fastening holes are opened on the matching steel plate, and side fastening bolts are installed one-to-one in the bolt fastening holes and the matching holes, and the threaded ends of the side fastening bolts are threadedly connected with the bolt sleeves.

[0011] Preferably, a steel bar skeleton is provided inside the split wall, and both sides of the steel bar skeleton protrude from the wall to form cantilevered steel bars, and bolt columns are cantileveredly provided at the upper end of the split wall.

[0012] A wall panel system comprises a base and a wall body which are arranged separately, and the base and the wall body which are arranged separately adopt the above-mentioned prefabricated wall panel.

[0013] A method for constructing a wall panel, using the above-mentioned prefabricated wall panel, comprises the following steps:

[0014] Step 1: Correct the fastening bolts reserved on the ground, and match the split base with the fastening bolts through the bolt holes, and then fix the split base on the ground with the fastening bolts. During the installation process, the leveling and position calibration of the split base are completed simultaneously;

[0015] Step 2: The split wall is matched with the split base by hoisting, so that the anti-tilt column and the matching steel plate enter the assembly groove. When the split wall and the split base are closely matched, the adjusting knob is rotated, and the reverse screw is driven to rotate by the rotation of the adjusting knob. The reverse screw drives the straightening extrusion plates on both sides to be squeezed toward the anti-tilt column. As the straightening extrusion plates on both sides tightly abut the anti-tilt column, the split wall is in an upright state under the abutment of the straightening extrusion plates on both sides. The anti-tilt column and the straightening extrusion plate are closely abutted, so that the prefabricated wall panel can be fixed without the need to install an inclined support;

[0016] Step 3: During the extrusion process of the straightening extrusion plates on both sides, the straightening extrusion plate on one side squeezes the push plate toward the side close to the structural adhesive storage compartment. During the extrusion process, the push plate drives the extrusion push plate inside the structural adhesive storage compartment to move, and then squeezes the structural adhesive stored inside the structural adhesive storage compartment into the glue injection groove through the pump injection groove, and completes the filling of the structural adhesive in the process of cooperating between the glue injection groove and the sealing groove to ensure the tightness of the combination of the two.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention adopts a split assembled wall panel structure. By pre-leveling and fixing the split base, the split wall is installed on the split base. After the installation, the split wall no longer needs to be fixed and adjusted by additional diagonal supports, thereby completely eliminating the use of a large number of diagonal supports in the construction area, ensuring the cleanliness of the construction area, and facilitating the movement of personnel and equipment in the construction area;

[0019] 2. The present invention adopts a split wall panel structure, which solves the problem of insufficient bonding strength between the traditional assembled wall panels and the reserved steel bars during installation. It does not require a large amount of concrete pouring inside the wall. Therefore, the assembled wall panels after installation are more convenient to disassemble in the later stage, which is conducive to the repeated use of assembled buildings.

[0020] 3. The present invention simultaneously pumps the structural adhesive during the leveling and installation process of the split wall, thereby ensuring the tightness of the connection between the split base and the split wall and improving the sealing performance of the device.

[0021] The present invention adopts a split assembled wall panel structure, which completely eliminates the use of a large number of inclined supports in the construction area and does not require a large amount of concrete pouring inside the wall, which is conducive to the movement of personnel and equipment in the construction area and facilitates the later disassembly of the assembled wall. The split base and the split wall are sealed and filled with structural adhesive, thereby improving the tightness of the combination of the two. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-4 , the present invention provides a technical solution:

[0029] Embodiment 1:

[0030] A prefabricated wall panel, comprising a split base 1 and a split wall 2, the split base 1 comprising a base 3, the base 3 being a double-layer rectangular parallelepiped stacking structure with the bottom surface of the upper layer inwardly reduced in proportion, a pair of matching steel plates 4 being fixedly mounted on the base 3, a pair of anti-tilt columns 5 being fixedly mounted between the matching steel plates 4, the anti-tilt columns 5 on both sides being fixedly connected to the base 3, and an assembly groove 6 for the matching steel plates 4 and the anti-tilt columns 5 to enter is provided at the bottom of the split wall 2;

[0031] Inside the assembly groove 6 of the split wall 2, there are straightening extrusion plates 7 on both sides of the anti-tilt column 5. The straightening extrusion plates 7 on both sides are threadedly connected with the reverse screw rod 8 through the threaded holes. An adjusting knob 9 is installed at one end of the reverse screw rod 8. The adjusting knob 9 is set in the knob hole 10 opened on the side of the split wall 2. The reverse screw rod 8 rotates to drive the straightening extrusion plates 7 on both sides to move towards each other, thereby limiting the left and right shaking of the split wall 2;

[0032] A structural glue storage compartment 11 is also provided at the top of the anti-tilt column 5, and an extrusion push plate 12 is also slidably provided in the structural glue storage compartment 11. The extrusion push plate 12 extends to the outside of the anti-tilt column 5 through a connecting rod 13 and is fixedly connected to a push plate 14. The push plate 14 movably abuts against a straightening extrusion plate 7 on one side. The structural glue storage compartment 11 is connected to a pair of glue injection grooves 16 provided on the outer edge of the base 3 through a pump injection groove 15 provided at the lower part of the anti-tilt column 5. The glue injection groove 16 provided on the outer edge of the base 3 abuts against a sealing groove 17 provided on the split wall 2.

[0033] In this embodiment, the split base 1 and the split wall 2 are separately arranged, and their installation adopts a distributed installation sequence. First, the split base 1 is installed on the ground, and then the split wall 2 is installed on the split base 1. The distributed installation method allows the split base 1 to be pre-leveled and corrected on the ground. After its installation is completed, the split wall 2 is installed by hoisting to ensure the verticality of the wall installation. Compared with the integrated assembled wall installation structure in the prior art, since the wall is not firmly combined with the ground, it must be fixed with inclined supports later to ensure the verticality of the adjacent assembled walls during the cement grouting process. The split base 1 in the present invention is tightly fixed to the ground by bolts. Since the split base 1 is provided with a protruding anti-tilt column 5, when the split wall 2 is hoisted After completion, by rotating the adjusting knob 9, the reverse screw rod 8 is driven to rotate through the rotation of the adjusting knob 9, and the reverse screw rod 8 drives the straightening extrusion plates 7 on both sides to be squeezed toward the anti-tilt column 5. As the straightening extrusion plates 7 on both sides tightly abut the anti-tilt column 5, the split wall 2 is forced to be in an upright state under the abutment of the straightening extrusion plates 7 on both sides, and in the extrusion process of the straightening extrusion plates 7, the straightening extrusion plates 7 squeeze the push plates 14 toward the side close to the structural adhesive storage compartment 11. The push plates 14 drive the extrusion push plates 12 inside the structural adhesive storage compartment 11 to move during the extrusion process, and then the structural adhesive stored in the structural adhesive storage compartment 11 is squeezed into the glue injection groove 16 through the pumping groove 15, and the filling of the structural adhesive is completed during the cooperation process between the glue injection groove 16 and the sealing groove 17, to ensure the tightness of the combination of the two.

[0034] Embodiment 2:

[0035] In this embodiment, a bolt hole 18 is opened on the split base 1, and the bolt hole 18 is connected with a bolt column 19 set on the ground. The bolt column 19 fixes the split base 1 to the ground by cooperating with the fastening bolt 20. The split base 1 is installed on the ground by cooperating with the fastening bolt 20 and the bolt column 19.

[0036] Embodiment three:

[0037] In this embodiment, a plurality of bolt fastening holes 21 are opened on one side of the split wall 2, and a plurality of bolt sleeves 22 are installed one-to-one on the side of the split wall 2 away from the plurality of bolt fastening holes 21. Matching holes 23 corresponding to the bolt fastening holes 21 are opened on the matching steel plate 4. Side fastening bolts 24 are installed one-to-one in the bolt fastening holes 21 and the matching holes 23. The threaded ends of the side fastening bolts 24 are threadedly connected with the bolt sleeves 22. By installing a plurality of side fastening bolts 24, the split base 1 and the split wall 2 are further fixed to prevent relative sliding between the two.

[0038] Embodiment 4:

[0039] In this embodiment, a steel frame is provided inside the split wall 2, and the steel frame has protruding steel bars 25 on both sides protruding from the wall. Bolt columns 19 are provided on the upper end of the split wall 2. Adjacent split walls 2 are tied together with the protruding steel bars 25 and concrete is poured, thereby casting and fixing the adjacent walls.

[0040] A wall panel system comprises a base and a wall body which are arranged separately, and the base and the wall body which are arranged separately adopt the above-mentioned prefabricated wall panel.

[0041] A method for constructing a wall panel, using the above-mentioned prefabricated wall panel, comprises the following steps:

[0042] Step 1: Correct the fastening bolts 20 reserved on the ground, and fit the split base 1 with the fastening bolts 20 through the bolt holes 18, and then fix the split base 1 on the ground through the fastening bolts 20, and simultaneously complete the leveling and position calibration of the split base 1 during the installation process;

[0043] Step 2: The split wall 2 is matched with the split base 1 by hoisting, so that the anti-tilt column 5 and the matching steel plate 4 enter the assembly groove 6. When the split wall 2 is closely matched with the split base 1, the adjusting knob 9 is rotated. The reverse screw rod 8 is driven to rotate by the rotation of the adjusting knob 9. The reverse screw rod 8 drives the straightening extrusion plates 7 on both sides to be squeezed toward the anti-tilt column 5. As the straightening extrusion plates 7 on both sides tightly abut the anti-tilt column 5, the split wall 2 is in an upright state under the abutment of the straightening extrusion plates 7 on both sides. The anti-tilt column 5 is closely abutted against the straightening extrusion plates 7, and the prefabricated wall panel can be fixed without the need to install an inclined support.

[0044] Step three: During the extrusion process of the straightening extrusion plates 7 on both sides, the straightening extrusion plate 7 on one side squeezes the push plate 14 toward the side close to the structural adhesive storage compartment 11, and the push plate 14 drives the extrusion push plate 12 inside the structural adhesive storage compartment 11 to move during the extrusion process, thereby squeezing the structural adhesive stored inside the structural adhesive storage compartment 11 into the glue injection groove 16 through the pumping groove 15, and completing the filling of the structural adhesive in the process of cooperating between the glue injection groove 16 and the sealing groove 17 to ensure the tightness of the combination of the two.
