Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building, concretely relates to a prefabricated slab for the rapid reconstruction of wall. BACKGROUND

[0002] The wall surface is beautified during indoor decoration, and the conventional beautifying method is to decorate the wall surface by painting. In order to save construction cost and construction time, a prefabricated decorative plate is used in the industry at present, and the wall beautifying and reconstruction efficiency is improved by using the plate with a decorative surface produced in advance to be spliced and installed on site. The prefabricated plates that are spliced together are seamlessly attached to each other to form a wall with a decoration.

[0003] The prefabricated plate has a structure that the plate with a decoration has connecting pieces on both sides, and the connecting pieces are used for quick splicing. However, the structure of most connecting pieces is a protrusion and a groove that are perpendicular to the side surface of the decorative plate, and the protrusion and the groove are inserted and combined in a direction parallel to the wall surface. However, after the installation of this structure is completed, the plates are associated with each other and there is no gap between the plates. If one of the prefabricated plates is damaged, the entire wall surface needs to be removed and replaced, which causes unnecessary damage to manpower. In order to avoid the above situation, some existing technologies change the protrusion and the groove that are perpendicular to the side surface to a protrusion and a groove that are parallel to the side surface. The direction of the insertion of the prefabricated plates is changed to be perpendicular to the wall surface. Although this structure can be used to individually remove the prefabricated plates, the structure is limited and the connection will become loose after a period of use.

[0004] Therefore, it is a big pain point in the industry to solve the problem of individual removal without affecting the connection strength. INVENTION CONTENTS

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] like Figures 1-6 As shown, a prefabricated panel for rapid wall renovation includes a decorative panel 1 and a connector 2. The decorative panel 1 includes a base plate 11 and a painted layer 12, with the painted layer 12 located on the surface of the base plate 11.

[0039] The connector 2 is located on the edge of the decorative panel 1. The connector 2 includes a first connecting end 21, a second connecting end 22 and a fixing member 23. Two adjacent decorative panels 1 are respectively a first decorative panel and a second decorative panel. The first decorative panel has a first connecting end 21 on both sides. The second decorative panel has a second connecting end 22 on both sides. The first connecting end 21 and the second connecting end 22 are detachably connected. The fixing member 23 detachably fixes the first connecting end 21 and the second connecting end 22.

[0040] Since the connectors 2 on both sides of the same decorative panel 1 have the same structure, and the connectors 2 between two adjacent decorative panels 1 are complementary, only the two adjacent prefabricated panels are individually connected after splicing, and not all the prefabricated panels are connected together. Therefore, only one or three prefabricated panels need to be removed during disassembly.

[0041] The substrate 11 is used to support the painted layer 12, which is used to draw lines, patterns and colors for decoration. The connector 2 is used to quickly and aesthetically connect the decorative panel 1.

[0042] Multiple connectors 2 can be provided depending on the height of the precast slab.

[0043] In one specific embodiment, the side of the substrate 11 away from the painted layer 12 is wavy to form multiple ventilation channels. The ventilation channels can increase the breathability between the decorative panel 1 and the wall, and also reserve space for the wall to expand due to heat.

[0044] In one specific embodiment, such as Figure 2 As shown, the decorative panel 1 also includes a protective layer 13, which covers the painted layer 12 to prevent the painted layer 12 from fading. The protective layer 13 can be a transparent layer, which not only protects the painted layer 12 but also increases reflectivity, making the colors of the painted layer 12 brighter.

[0045] In one specific embodiment, such as Figures 3-6 As shown, the first connecting end 21 includes a tenon 211, and cavities 212 are provided on both sides of the tenon 211. The second connecting end 22 includes a mortise 221, and groove walls 222 are provided at both ends of the mortise 221. The tenon 211 is inserted into the mortise 221 along the bottom surface of the mortise 221, and the groove walls 222 and the cavities 212 fit together perfectly.

[0046] A fixing groove 231 is provided above the cavity 212, and the fixing groove 231 extends downward to the mortise groove 221. The fixing member 23 connects the fixing groove 231 and the mortise groove 221.

[0047] The structure between the connectors 2 is cleverly designed. First, the tenon 211 and the mortise 221 are interlocked according to their structure. Then, the fastener 23 is inserted into the mortise 221 and the fixing groove 231 to tighten the connection. The three are tightly connected, and the special splicing method also increases the aesthetics of the precast panel.

[0048] In one specific embodiment, such as Figures 3-5 As shown, the first decorative panel 1 has a first connecting plate at the upper and lower sides of the first connecting end 21; the second decorative panel 1 has a second connecting plate at the upper and lower sides of the second connecting end 22, and the first connecting plate and the second connecting plate are attached to each other.

[0049] In one specific embodiment, such as Figure 3 , 4 As shown, a disassembly groove 213 is provided at the junction of the fastener 23 and the first connecting plate 3. The area of ​​the disassembly groove 213 should not be too large. If it is too large, it will not only affect the firmness of the fastener 23, but also cause a large area of ​​dust accumulation, affecting the aesthetics of the precast panel wall. In addition, the fastener 23 is not large in size, and the force required for disassembly is not strong. Only a small disassembly groove 213 is needed to accommodate the tool for prying the fastener 23.

[0050] In one specific embodiment, such as Figure 6 As shown, the fastener 23 has a slot 232 at the disassembly slot 213 position, which can provide a support point for the tool during disassembly and is more conducive to force bearing.

[0051] In one specific embodiment, the substrate 11, the painted layer 12, and the protective layer 13 are integrally connected, and deformation or cracks should not occur between the three, resulting in a longer service life.

[0052] In another specific embodiment, the substrate 11, the painted layer 12, and the protective layer 13 are detachably connected. By detaching the painted layer 12 and the substrate 11, the painted layer 12 can be replaced to try different decorative styles and reduce replacement costs.

[0053] During assembly, a decorative panel 1 with a first connecting end 21 and a decorative panel 1 with a second connecting end 22 are combined. The tenon 211 and the mortise 221 are inserted into each other, and the groove wall 222 and the cavity 212 fit together perfectly. The fastener 23 is inserted into the fixing groove 231 and the mortise 221 with an interference fit. The fastener 23 fits perfectly with the fixing groove 231 and the mortise 221. At this time, the surface of the connector 2 is a plane, and the two prefabricated panels are fixed.

[0054] When one of the precast slabs needs to be replaced, insert the hook or pry bar into the disassembly groove 213 and engage it with the slot 232. Pry the fastener 23 to remove it, and then remove the precast slab by following the gap between the fastening groove 231 or the mortise 221.

[0055] In one specific embodiment, the substrate 11 is a metal plate with a thickness ranging from 3mm to 5mm. The metal plate has high strength and is not easily deformed. The connector 2 is preferably made of wood, which has high elasticity and makes the connection more secure.

[0056] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0057] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0058] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
