Description

Technical Field

[0001] The present invention relates to the technical field of wall decoration of buildings, and in particular to a magnetic keel wall system based on a modular wall and a construction method thereof. Background Art

[0002] Modular construction is the most integrated industrialized construction method. The spatial structure module integrates decoration, water and electricity pipelines. In existing modular buildings, the walls are generally decorated with wet work technology, such as using putty for wall decoration. However, when the wall cracks due to building settlement or uneven splicing of prefabricated walls, the putty layer on the wall will crack, seriously affecting the appearance of the facade.

[0003] Although the traditional prefabricated wall technology can solve the above problems, there will still be corresponding derivative problems. For example, the use of various glues to paste decorative panels on the wall will cause a certain degree of indoor air pollution. For example, it is difficult to modify the pipeline after completion, and a large amount of construction waste, noise and air pollution will be generated during on-site cutting; in addition, if the wall surface is uneven, if the pasting method is used, the decorative panel will be uneven and there is a risk of falling off.

[0004] Although the problem of uneven decorative panels is solved when expansion bolts and combined keels are used for assembly, the existing wall will be damaged when the impact drill is used to drill holes, and a large amount of dust and noise pollution will be generated. The decorative panels are locked to the keels with self-tapping screws, which makes replacement inconvenient. Summary of the invention

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Reference Figures 1 to 8As shown, a magnetic keel wall system based on a modular wall includes a prefabricated wall 1, wherein the prefabricated wall 1 is provided with a plurality of anchor bolts 11; an integral keel 2, wherein the integral keel 2 includes a vertical keel 21 and a connecting screw 23, wherein the connecting screw 23 passes through the vertical keel 21 and is threadedly connected to the anchor bolt 11, so that the integral keel 2 is fixedly connected to the prefabricated wall 1; and a supporting assembly 3, wherein the supporting assembly 3 includes a vertical keel 21 fixedly provided at the bottom side end thereof. A skirting base 31 is provided on the surface, and a skirting board 32 is fixedly arranged on the skirting base 31. The skirting board 32 is provided with an edge strip portion 321 protruding from the upper end surface of the skirting base 31. The edge strip portion 321, the upper end surface of the skirting base 31, and the front end surface of the vertical keel 21 surround to form a slot 33; it also includes a decorative panel 4, the lower end of the decorative panel 4 is embedded in the slot 33, and the back side of the decorative panel 4 is magnetically attracted to the integral keel 2.

[0039] Specifically, the prefabricated wall 1 is processed at the factory end, and the prefabricated wall 1 includes a plurality of steel bars 12 and a concrete layer 13. Before the plurality of steel bars 12 are tied, a laser line is drawn using a laser level, and an anchor bolt 11 is placed every 500 mm along the laser line, and then spot welded with the steel bars 12 to embed them in the cage of the steel bars 12 in advance, and then concrete is poured to form the prefabricated wall 1 in an integrated manner.

[0040] The pre-embedded spacing of the anchor bolts 11 in the vertical direction is 500mm±20mm, and the pre-embedded spacing of the anchor bolts 11 in the horizontal direction depends on the split specifications of the decorative panel 4, and the pre-embedded error is within 20mm, thereby ensuring the firmness of the connection between the integral keel 2 and the prefabricated wall 1. Figure 6 As shown, the anchor bolt 11 includes a threaded sleeve 111 and a limiting rib 112 arranged perpendicular to the threaded sleeve 111. The threaded sleeve 111 and the limiting rib 112 are connected by welding to ensure firmness. The threaded sleeve 111 is drilled and threaded. Limiting ribs 112 are provided on both sides of the threaded sleeve 111. The limiting ribs 112 on both sides are welded to the steel bars 12 of the prefabricated wall 1 to ensure that the embedded point of the anchor bolt 11 is accurate and does not move.

[0041] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the integral keel 2 also includes a transverse keel 22. The two side end surfaces of the vertical keel 21 are provided with a plurality of socket holes 211 arranged in the height direction. The two ends of the transverse keel 22 are provided with socket buttons 221 embedded in the socket holes 211. The transverse keel 22 can be formed by bending a 0.8 mm sheet metal. Before bending, a vertically penetrating wire pipe groove 222 is punched to form the wire pipe groove 222. The wire pipe groove 222 is used for pre-embedding and positioning of the water and electricity pipelines 5. The socket buttons 221 of the groove structure are punched on both sides. During assembly, the socket buttons 221 of the transverse keel 22 can be directly inserted into the socket holes 211 of the vertical keel 21. The processing and assembly process of the transverse keel 22 is simple.

[0042] Reference Figure 2 and Figure 3 As shown, the front end surface of the vertical keel 21 is provided with a recessed portion 212, and the screw head of the connecting screw 23 is embedded in the recessed portion 212, so as to prevent the screw head of the connecting screw 23 from interfering with the decorative panel 4. The connecting screw 23 is preferably a hexagon socket screw. Figure 2 As shown, the connecting screws 23 and the matching flat washers 24 and nuts 25 are locked with the slots of the vertical keels 21, and then the vertical keels 21 are vertically placed against the prefabricated wall 1. When the surface of the prefabricated wall 1 is uneven, the amount of screwing of the connecting screws 23 into the threaded sleeve 111 can be adjusted, and the vertical laser emitted by the laser level can be used to ensure that the adjacent vertical keels 21 are flush and the verticality of the vertical keels 21 is maintained, thereby solving the problem of unequal splicing of the decorative panels 4 due to the uneven wall surface.

[0043] The front end surface of the decorative panel 4 can be sprayed with various colors, patterns or designs to play a decorative role. The rear end surface of the decorative panel 4 is provided with a magnetic material. By selecting magnetic materials with strong adsorption force, anti-peeling force and not easy to demagnetize, such as neodymium iron boron magnets, samarium cobalt magnets, etc., the service life is guaranteed. By adsorbing the decorative panel 4 on the vertical keel 21 or the horizontal keel 22, the installation operation is simple.

[0044] During assembly, by inserting the lower end of the decorative panel 4 into the slot 33, the back of the decorative panel 4 is magnetically attracted to the integral keel 2, so that the decorative panel 4 is installed and fixed, and the installation operation is simple. The edge trimming strip 321 of the skirting board 32 can not only fix the decorative panel 4, but also be close to the decorative panel 4 to achieve the effect of decorative trimming.

[0045] Reference Figure 4 and Figure 5As shown, the support assembly 3 further includes a self-tapping screw 34, which is passed through the skirting base 31 and connected to the vertical keel 21. The bottom of the skirting base 31 abuts against the floor. By selecting a suitable installation height, the lower end of the installed skirting base 31 abuts against the floor. When the skirting base 31 is installed in an accurate position, the lower end of the skirting line board 32 assembled therewith can be guaranteed to abut against the floor, achieving seamless splicing and making the wall finish beautiful. The floor is used as the positioning reference surface, and the installation and positioning are simple, and no other auxiliary tools are required.

[0046] The support assembly 3 also includes a magnet sheet 35, and the skirting board base 31 includes an upper clamping portion 311 extending upward and a lower clamping portion 312 extending downward, and the magnet sheet 35 is inserted between the upper clamping portion 311 and the lower clamping portion 312, and the skirting board plate 32 is magnetically attracted to the magnet sheet 35. During assembly, the magnet sheet 35 is inserted laterally between the upper clamping portion 311 and the lower clamping portion 312 to achieve installation and fixation of the magnet sheet 35, and the installation operation is simple.

[0047] The skirting board 32 can be made of aluminum profile material, and a magnetic material layer, such as a magnetic sticker with adhesive backing, is fixed on its back, so that the skirting board 32 is magnetically attracted to the magnet sheet 35 and is not easy to fall off after installation.

[0048] The upper end of the skirting base 31 is provided with a first buckling portion 313 buckled into the skirting line board 32, and the skirting line board 32 is provided with a second buckling portion 322 buckled with the first buckling portion 313. During assembly, the skirting line board 32 is pushed in a direction perpendicular to the front end surface of the skirting base 31, so that the first buckling portion 313 is deformed, and then the first buckling portion 313 and the second buckling portion 322 are buckled with each other, so that the skirting line board 32 is installed and fixed, and the installation operation is simple.

[0049] The skirting base 31 and the skirting plate 32 can be connected by the first buckle part 313 and the second buckle part 322 mentioned above, or by magnetic attraction of the magnet sheet 35, or by the combination of the two, to achieve a fixed connection between the skirting base 31 and the skirting plate 32.

[0050] On the other hand, the present invention provides a construction method of a magnetic keel wall system based on a modular wall, the construction method comprising the following steps:

[0051] S1, pouring and connecting the prefabricated wall 1 with the floor according to the construction design requirements;

[0052] S2, vertically place the vertical keel 21 against the prefabricated wall 1, use the vertical laser emitted by the laser level to level the vertical keel 21, and then connect the vertical keel 21 to the prefabricated wall 1 through the connecting screws 23;

[0053] S3. Arrange the water and electricity pipeline 5 according to the water and electricity points in the construction design. The water and electricity pipeline 5 passes through the transverse keel 22 through the wire pipe groove 222, and then insert the two ends of the transverse keel 22 into the socket hole 211 through the socket buckle 221;

[0054] S4, magnetically attaching the decorative panels 4 to the integral keel 2 in sequence;

[0055] S5. Connect the skirting board base 31 to the vertical keel 21 by using self-tapping screws 34, wherein the lower end of the skirting board base 31 abuts against the floor;

[0056] S6. Insert the magnet sheet 35 laterally between the upper clamping part 311 and the lower clamping part 312 of the skirting board base 31, and push the second clamping part 322 of the skirting board line plate 32 along the front to lock with the first clamping part 313 by overcoming the deformation of the first clamping part 313.

[0058] First, the highly integrated assembly decoration technology based on modular buildings. In the production stage of modular prefabricated walls 1, the present invention innovatively proposes the idea of ​​integrated structure-decoration design. Through standardized design, anchor bolts 11 for fixing assembled walls are pre-buried in advance. When assembling the decorative panels 4 later, there is no need to drill holes.
