It also has the function of noise reduction and sound insulation, and is durable and widely used in the field of building decoration. However, due to the problem of fixing method, traditional EPS board cannot be produced in larger sizes, otherwise it will cause loose fixing, resulting in cracks in the topcoat or the whole piece falling off, which will cause major engineering quality risks. In addition, the relief board must be prevented from being installed crooked during installation, and auxiliary positioning tools are required, which makes it impossible to install efficiently. Therefore, it is necessary to study a new relief board installation structure and construction method to improve the stability and firmness of the relief board when it is fixed.

A spring steel wire runs horizontally through the guide plug block. The spring steel wire is guided by the wire guide seats on both sides of the positioning movable plate and then extends to both sides of the relief plate. The spring steel wire can pull the plug plate up and down to make the plug plate overlap or move away from the corresponding hole.
[0005] Furthermore, the fixing part includes threaded steel, a steel disc is welded to the front end of the threaded steel, and a nut is installed at the rear end. The length of the threaded steel can completely penetrate the installation hole and the wall hole.

DETAILED DESCRIPTION
[0012] The present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0013] See also Figure 1-7 , the present invention provides a technical solution of an EPS relief board installation structure and a construction method: Embodiment 1: This embodiment provides an installation structure of an EPS embossed board according to Figure 1 and Figure 2As shown, it includes a relief plate 1, a wall 2 and a fixing piece 3. The relief plate 1 is arranged on the outer facade of the wall 2 and is assisted in installation and fixing by the fixing piece 3. A mounting hole 4 is opened at the center of the relief plate 1. A groove with a certain depth is opened at the front end of the mounting hole 4. The depth of the groove is consistent with the thickness of the steel disc 32 in the fixing piece 3 to ensure that after the fixing piece 3 is installed on the relief plate 1, the steel disc 32 and the surface of the relief plate 1 form a complete plane; a wall hole 5 is opened through the center point of the position where the relief plate 1 needs to be installed on the wall 2. When the relief plate 1 is installed on the wall 2, the fixing piece 3 can penetrate the mounting hole 4 and the wall hole 5 to install and connect the relief plate 1 and the wall 2 together.
[0014] The fixing part 3 includes a threaded steel bar 31, a steel disc 32 is welded to the front end of the threaded steel bar 31, and a nut 33 is installed at the rear end. The thickness of the steel disc 32 is consistent with the thickness of the groove on the front side of the mounting hole 4, and the length of the threaded steel bar 31 can completely penetrate the mounting hole 4 and the wall hole 5. When the threaded steel bar 31 penetrates and connects the relief plate 1 and the wall 2, the steel disc 32 and the nut 33 can provide tensile force on the front side of the relief plate 1 and the back side of the wall 2, so that the relief plate 1 and the wall 2 are installed together through the fixing part 3.
[0015] like Figure 3 As shown, a positioning groove 7 is provided on the back of the relief plate 1, and an axle rod 8 is provided at the upper end of the positioning groove 7. A positioning movable plate 9 is mounted in the positioning groove 7 by rotating the axle rod 8. The upper end of the positioning movable plate 9 is connected by the axle rod 8, and the lower end is freely hanging. A corresponding hole 10 is provided on the positioning movable plate 9. When the positioning movable plate 9 is in a freely hanging state, the corresponding hole 10 can be completely aligned with the wall hole 5 on the wall 2. When the relief plate 1 is installed on the wall 2, in order to ensure the decorative effect of the relief plate 1, it is necessary to ensure that the relief plate 1 is level. During installation, when aligning the mounting hole 4 on the relief plate with the wall hole 5 of the wall 2, if the relief plate 1 is skewed and the positioning movable plate 9 is always in a free-hanging state, the corresponding hole 10 and the mounting hole 4 cannot be fully aligned. Only when the relief plate 1 is completely horizontal can the mounting hole 4 be aligned with the corresponding hole 10. The construction personnel can observe the horizontal state of the relief plate 1 through the corresponding hole 10 on the positioning movable plate 9, thereby ensuring that the relief plate 1 can be installed horizontally, and this alignment method does not require the participation of other tools, and the operation is simpler and more convenient. The thickness of the positioning movable plate 9 does not exceed the positioning groove 7, ensuring that the back of the relief plate 1 is in the same plane as the back plate of the relief plate 1, thereby improving the flatness of the back plate of the relief plate 1.
[0016] A guide plug block 11 is fixed below the corresponding hole 10 on the positioning movable plate 9, and a plug plate 12 is longitudinally slidably sleeved on the rear of the positioning movable plate 9 through the guide plug block 11. A through hole is horizontally penetrated on the guide plug block 11, and a spring steel wire 13 is passed through the through hole. The spring steel wire 13 is guided by the steel wire guide seats 14 installed on both sides of the positioning movable plate 9 and extends to both sides of the relief plate 1. The spring steel wire 13 has a certain elastic force and recovery performance. When the spring steel wire 13 is in a free extension state, such as Figure 5 As shown, the upper end portion of the insert plate 12 extends into the corresponding hole 10, and when the spring wire 13 is in a stretched state at both ends, as shown in FIG. Figure 6 As shown, the spring steel wire 13 pulls the plug plate 12 to move downward, and the upper end of the plug plate 12 is separated from the corresponding hole 10, leaving the corresponding hole 10 open to facilitate the threaded steel 31 to pass through; and the upper end of the plug plate 12 has an arc, and the arc is the same as the inner diameter of the corresponding hole 10. When the fixing member 3 is installed, the spring steel wire 13 is released. Under the elastic recovery effect of the spring steel wire 13, the plug plate 12 can be driven to move upward again and abut against the bottom of the threaded steel 31, so that the upper end of the plug plate 12 can be stuck in the thread line of the threaded steel 31, thereby preventing the occurrence of thread backflow and improving the stability of the fixing member 3.
[0017] A reinforcing plug block 6 is installed on the outer facade of the wall 2. When the plug plate 12 moves downward and away from the corresponding hole 10, the lower end can be inserted into the reinforcing plug block 6, and when the plug plate 12 moves upward and is stuck under the threaded steel bar 31, a part of the lower end of the plug plate 12 is still inserted in the reinforcing plug block 6. The plug plate 12, the guide plug block 11 and the reinforcing plug block 6 can further improve the connection effect between the relief plate 1 and the wall 2.
[0018] An adhesive is first used to fill the connection between the relief plate 1 and the wall 2. Before the adhesive solidifies, the position of the relief plate 1 is fine-tuned by positioning the movable plate 9 to ensure that the relief plate 1 does not deviate up, down, left, or right. Then, threaded steel with a steel disc is passed through the wall hole 5 and the mounting hole 4 to assist in fixing the relief plate. The threaded steel penetrates the masonry wall surface to ensure that it is tightly combined with the masonry wall surface. Subsequently, a nut 33 is installed on the inner side of the masonry wall to ensure that the entire reinforcement can be pulled against the masonry wall surface; the nut 33 can also be replaced by an inner steel disc, which is welded to the rear end of the threaded steel 31, so that the steel discs on both sides are pulled against the relief plate 1 and the wall 2 through the threaded steel. When applying the adhesive, it is necessary to avoid the positioning groove 7 to prevent the adhesive from affecting the positioning effect of the positioning movable plate 9. Since the bonding thickness of the adhesive is generally 3 to 8 mm, the spring steel wire 13 uses a steel wire with a diameter smaller than the thickness of the adhesive. In this way, when the relief plate 1 is docked with the wall 2, the unsolidified adhesive will not affect the pulling of the spring steel wire 13. When the relief plate 1 is installed, the spring steel wire 13 can be buried in the adhesive without affecting the bonding effect between the relief plate 1 and the wall 2. Through the bonding effect of the adhesive and the auxiliary fixing effect of the fixing member 3, the installation stability of the relief plate 1 can be further improved, and the risk of the relief plate 1 falling can be effectively reduced.
[0019] Embodiment 2: This embodiment provides an installation and construction method of EPS relief board The specific steps include: 1. Processing of relief panels: Before installing the relief panels, the overall size of the relief panels should be measured on site, and the partition layout of the entire relief panel should be planned in advance to ensure that the appearance of the relief panel is not affected. At the same time, the layout location of the reinforcements should be determined in advance, and the installation holes for the reinforcements should be reserved to ensure that the placement points of the reinforcements will not affect the surface texture, and the surface of the reinforcements should be 1 cm lower than the normal surface, so that all the finished decorative surfaces in the later stage are on the same plane. The processing uses a CNC engraving machine, and the completed 3D modeling is imported into the machine for processing in advance. During processing, a fixed-size positioning groove is opened on the back of the relief panel, and positioning movable plates, plug plates, wire guide seats, spring steel wires and other structures are installed in the positioning groove. After processing, a special alkali-resistant mesh cloth with a mesh size of 3mm×3mm and anti-cracking mortar are used for surface treatment and drying to ensure the appearance quality and use function of the relief panel.
[0020] 2. Wall processing: Clean the hole in advance at the exact center of the wall where the relief panel needs to be installed, and install the reinforcement plug at a certain distance below the wall hole. The reinforcement plug can be connected by bonding or screws.
[0021] 3. Construction of adhesive on the back of the relief board: clean the dust and debris on the surface of the relief board and the masonry wall, use adhesive to paste the relief board according to the relief board layout planned in advance, and position the relief board through the corresponding holes when pasting to ensure that the relief board is completely level.
[0022] 4. Construction of fixing of buried plate-type threaded steel bars: weld the threaded steel bars with a steel disc with a thickness of 1mm in advance. After the relief plate is attached to the wall, immediately pull the spring steel wire to both sides to drive the plug plate to move down and out of the positioning hole. Then, pass one side of the threaded steel bar through the relief plate and the masonry wall. After it is firmly fixed, connect the threaded steel bar with the nut on the inside of the wall to ensure that the entire fixing is reliable and not loose. Then loosen the spring steel wire and rely on the restoring force of the spring steel wire to pull the plug plate up and get stuck under the threaded steel bar. Finally, wait for the adhesive to completely solidify to complete the installation and fixation of the relief plate.
[0023] 5. Surface anti-crack mortar repair: Use special alkali-resistant mesh cloth and anti-crack mortar to repair between the relief board and the masonry wall, and between the joints of the relief board to avoid later cracking. The embedded plate type fixed steel disc needs to be repaired with surface anti-crack mortar, and the anti-crack mortar should fill the groove densely.
[0024] Embodiment 3: This embodiment provides a method for processing EPS embossed board 1. Raw material processing: The raw material of the relief board is a 3m×1.2m×0.6m molded polystyrene board (bulk density is 18kg / m3). According to the pre-determined separation method, the finished 4m×2.9m relief board will be divided into four pieces of 0.96m×2m and two pieces of 0.98m×2m, a total of six pieces, with a side area of 0.7m 2 and 0.5m 2 The bisected 3D model is input into the CNC engraving machine, which will complete the preliminary processing of the polystyrene board. The weight of the processed molded polystyrene board is between 8.64kg and 8.82kg and 12.096kg and 12.348kg, and mounting holes for fixing the relief board have been reserved.
[0025] 2. The first anti-cracking mortar treatment: Apply the anti-cracking mortar on the surface of the finished product processed by the engraving machine with a brush, and at the same time press the special alkali-resistant mesh cloth with a mesh of 3mm×3mm to ensure that the mesh cloth is evenly pressed into the anti-cracking mortar. The thickness of the anti-cracking mortar is controlled at 3-5mm. Then check whether the surface is flat, whether the corners are straight and neat, and repair the defective parts in time. After the repair is completed, let it dry for more than 48 hours.
[0026] 3. Construction of the second anti-crack mortar: After the surface of the first anti-crack mortar is dry and formed, the second anti-crack mortar is constructed. Use a brush to brush the surface of the relief board to repair the rough surface, obvious small pits and other obvious defects. The thickness of the anti-crack mortar is controlled at 2-3mm to ensure that the surface is smooth, clean, uniform in color, without smears, and the corners are neat and smooth to achieve the molding effect. After the repair is completed, let it dry for more than 72 hours; 4. Installation and construction of EPS relief board.
[0027] 5. Surface repair of relief board: After the relief board is installed, use a brush to apply anti-cracking mortar on the relief board joints, fixings, and the joints between the relief board and the wall, and press in a special alkali-resistant mesh cloth with a mesh size of 3mm×3mm to ensure that the mesh cloth is evenly pressed into the anti-cracking mortar. The thickness of the anti-cracking mortar is controlled within 4mm. After the mortar is dry and formed, use a brush to apply the anti-cracking mortar again to ensure that the fixings and the relief board joints are smooth and flat without obvious marks. The thickness of the anti-cracking mortar is controlled within 3mm.
[0028] 6. Exterior wall paint construction: Use a paint spray machine to spray the surface of the relief board. After spraying, check for obvious defects and use a brush to repair the defective parts.
