Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated decoration, and in particular relates to a dry-hanging decorative panel with a hidden leveling keel and a preparation and installation process thereof. Background Art

[0002] In the prior art, the construction methods of prefabricated walls are mainly divided into two methods: gluing and dry hanging.

[0003] The gluing is mainly achieved by using clips on both sides of the veneer, and the connection between the veneer and the wall is achieved by using structural glue or other organic foam adhesives. Dry hanging is mainly achieved by dry hanging components. Among them, the gluing method has technical problems such as a long construction process, a high level of professional construction and difficulty in quality control, it is difficult to separate the wall and thus cannot add sockets, and there is organic chemical pollution to the indoor environment.

[0004] Among them, the dry hanging processing method has the following technical problems: 1. Between the dry hanging integrated decorative panels and the lightweight partition walls, leveling keels or clips are required to form a 10-15mm cavity, occupying the indoor use space and thus reducing the net size of the space. For example, the use of leveling modules in residential stairwells to reduce the size of the stairwell affects the minimum size of the fire escape; when the living room, bedroom, dining room and other rooms of affordable housing are small, the use area will be reduced by 5% to 10%. 2. For dry hanging reversible integrated wall panels, when the width of the decorative panel is greater than 600mm, structural adhesives are used for pasting, resulting in the damage of the decorative panel after removal and inability to reinstall. 3. The space between the bathroom and the kitchen is limited. In order to meet the net width, the thickness of the partition wall is reduced to 60mm, which does not meet the length-to-thickness ratio of ≤40 in GB / T15762-2020 "Autoclaved Aerated Concrete Board". 4. In order to meet the separation of pipelines, the socket switch wire pipe and water supply pipe are placed between the decorative panel and the partition wall, occupying 20~35mm of space.

[0005] In addition, some workers use a drill to drill slots on the wall after the wall installation is completed for the installation of the keel, thereby reducing the occupied indoor space and increasing the net size of the indoor space. However, this method will consume a lot of manpower and material resources. At the same time, a large amount of smoke and dust will be generated during the opening of the slot, which will cause damage to the health of the construction workers. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, the present invention provides a dry-hanging decorative panel with hidden leveling keels and a preparation and installation process thereof, so as to solve the technical problems that the dry-hanging wall panels occupy a large indoor space during installation and the solution requires a lot of manpower and material resources.

[0007] To achieve the above purpose, the specific technical solutions of the present invention are as follows: In the first aspect, a preparation and installation process of a dry-hanging decorative panel with a hidden leveling keel, the specific steps are as follows: S1, frame construction, according to the size of each partition board to be constructed, the steel mesh sheets of corresponding sizes are manually tied, and multiple inserted thousand rods are detachably fixed on the corresponding steel mesh sheets through clamps.

[0009] S3, inserting the skeleton, inserting multiple steel mesh sheets into the mold after casting through an inserting machine, and after insertion, transporting them together with the mold to a curing room for gasification and initial solidification to form a blank body.

[0010] S4, pull out the plug rod inserted into the blank body.

[0011] S5, demoulding, the blank body after resting is transferred to the cutting area. The flip demoulding mechanism flips the blank body and places it on the trolley. After it is placed stably, the flip demoulding mechanism grabs the mold of the blank body except the bottom surface and disassembles and separates it.

[0012] S6, segmentation, the blank body is driven by the trolley to pass through the vertical cutting device and the horizontal cutting device in sequence to perform the cutting process. Through the cutting, the blank body is sequentially segmented into a plurality of segmented blanks with the same thickness as the required wallboard body.

[0013] S7, side notching, the divided and stacked split blanks are conveyed by a conveyor belt through a notching device, and the notching device is provided with a notching knife at the dividing surface of each stacked split blank. When the stacked split blanks pass the position of the notching knife under the conveyor belt, the excess material on the side of the split blanks is scraped off to form the required installation notches on the wall panel body.

[0014] S8, high temperature steam curing, the refined blank is turned over by the turning table, returned to the trolley, and transported by the trolley to the autoclave for autoclave treatment to form the required wall panel body.

[0015] S9, splicing and placing, arranging the main bodies of the formed wall panels in sequence.

[0016] S10, installing the keel, placing the keel body in the corresponding installation slot, and driving the expansion bolts into the keel body to achieve a fixed connection between the keel body and the wall panel body.

[0017] S11, keel leveling, rotating the limit nut on the expansion bolt, controlling the length of the expansion bolt extending into the wall panel body, so that each keel body to be installed subsequently is on the same vertical plane.

[0019] S13, repeating steps S10 to S12 to complete the installation of each decorative panel on the entire wall.

[0020] Furthermore, the blade head of the slotting knife in step S7 is a stepped arrangement blade head, so that when the stacked split blanks pass the position of the slotting knife under the conveyor belt, the slotting knife will gradually penetrate into the side of the split blanks, and finally scrape off the residual material of 5 cm long and 1.0~2.0 cm deep.

[0021] Furthermore, in step S1, the steel mesh sheet is installed at the center of the casting mold so that the steel mesh sheet is located on the middle layer of the finally formed wall panel body.

[0022] Furthermore, in step S10, the formed wall panel bodies are arranged in sequence along the horizontal direction, and the installation notches on the wall panel bodies are perpendicular to the ground. The installation notches between the left and right adjacent wall panel bodies are spliced ​​to form a joint groove that matches the keel assembly.

[0023] Furthermore, during the installation of the decorative panel in step S13, the clamping groove on one side of the decorative panel is preferentially engaged with the clamping portion on the corresponding keel body. After the fixing of one side of the decorative panel is completed, another keel body is installed in the adjacent joint groove. The clamping portion on the keel body is inserted into the clamping groove on the other side of the decorative panel during the installation process, thereby completing the installation and fixing of the entire decorative panel.

[0024] Furthermore, in step S10, the formed wallboard bodies are arranged in sequence along the vertical direction, and the joint seams of the wallboard bodies of two adjacent layers are staggered in the vertical direction. The installation notches between the two adjacent wallboard bodies are spliced ​​to form a joint groove that matches the keel assembly.

[0025] Furthermore, in step S13, a hanging piece that matches the clamping part of the keel body is preferentially installed on the back of the veneer. When the veneer is attached to the wallboard body, the hanging piece on the veneer extends into the keel body through the clearance slot. The veneer is moved in the length direction of the keel body so that the hanging piece on the veneer can be clamped with the clamping part of the keel body during the movement.

[0026] In a second aspect, a dry-hanging decorative panel with a hidden leveling keel comprises a wall assembly, a decorative panel and a keel body. The wall assembly comprises a plurality of wall panel bodies arranged in sequence, each of which has an installation slot on its corner edge. The keel assembly is installed in the installation slot, and a clamping portion is provided at the outer end. The decorative panel is clamped and matched with the clamping portion.

[0027] Furthermore, the keel body is in a "J" shape, and is divided into a mounting portion at the inner end and transition portions arranged on both sides of the mounting portion. The mounting portion is fixed in the mounting notch by bolts. A clearance space is formed between the transition portions on both sides, and the clamping portion is arranged at the outer end of the transition portion. The edges of both sides of the decorative panel are provided with clamping grooves that match the clamping portion. The clamping grooves on the decorative panel are clamped and matched with the clamping portion.

[0028] Furthermore, each of the wall panel bodies is arranged in sequence along the vertical direction, and the installation notches on the side are parallel to the horizontal plane. The keel body includes an inner installation portion and an upwardly bent clamping portion. A hanging piece that matches the clamping portion is fixed on the inner side of the decorative panel. The hanging piece is clamped and matched with the clamping portion.

[0029] Compared with the prior art, the present invention has the following advantages: 1. The present invention forms installation notches by scraping off excess material from the side of the initially solidified wallboard body during the processing of the wallboard body. The keel assembly can be embedded in the installation notches during wall assembly, so that the installation of the decorative panel does not occupy additional indoor space, and avoids the need to use a drill to open the notch during the installation process, which consumes a lot of manpower and material resources, and the smoke and dust generated during the construction cause harm to the health of the construction workers.

[0030] 2. The keel body of the present invention is installed by using expansion bolts to ensure the stability of the installation. At the same time, by setting a limit nut on the inner side of the expansion bolt, the length of the expansion bolt extending into the wall panel body is controlled by rotating the limit nut, so that the keel bodies in each keel assembly are on the same vertical plane, thereby ensuring the flatness of each part of the decorative panel installed on the keel body.

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] Example 1

[0036] like Figure 1 and 2 As shown, a dry-hanging decorative panel with a hidden leveling keel includes a wall assembly, a decorative panel 2 and a keel assembly 3. The wall assembly includes a plurality of wall panel bodies 1 arranged in a horizontal direction. An installation slot 4 is provided on the corner edge of each wall panel body 1. The keel assembly 3 is installed in the installation slot 4, and a clamping portion 6-3 is provided on the outer end. A clamping slot 5 matching the clamping portion 6-3 is provided on both side edges of the decorative panel 2. The clamping slot 5 on the decorative panel 2 is clamped with the clamping portion 6-3, so that the decorative panel 2 can be fixed on the wall panel body 1 without occupying additional indoor space.

[0037] In some embodiments, the installation notches 4 between the two adjacent wall panel bodies 1 can be spliced ​​to form a joint groove that matches the keel assembly 3. The keel assembly 3 is arranged in the joint groove. The joint groove increases the installation space of the keel assembly 3, which facilitates the adaptive adjustment and clamping of the keel assembly 3.
