Description

Technical Field

[0001] The present invention relates to the technical field of building structures, and particularly relates to an installation structure of a ceramic thermal insulation composite board and a construction method thereof. Background Art

[0002] At present, the ceramic thermal insulation integrated board on the market is usually bonded to the base wall with a special adhesive, and the ceramic thermal insulation integrated board is assisted mechanically fixed by anchoring adapters and connectors on the base wall, so as to install the ceramic thermal insulation composite board; however, with the development and progress of building energy conservation in the whole society, the national requirements for building energy conservation indicators are increasing day by day. Taking the "75" energy conservation in cold and severe cold regions as an example, the designed thickness of the thermal insulation layer of the ceramic thermal insulation integrated board is basically between 120 - 150 mm. The increase in the thermal insulation thickness will inevitably lead to an increase in the fixing torque required during the installation of the ceramic thermal insulation integrated machine, making the fixing safety of the ceramic thermal insulation integrated board unable to be guaranteed, resulting in the situation of the ceramic thermal insulation integrated board falling off.

[0003] The prior art CN110607882A discloses an installation structure of a ceramic thin plate thermal insulation decorative composite board and a construction method thereof. The installation structure includes a ceramic thin plate, a back lining steel strip, a fastener, a thermal insulation board and a transition angle code. An installation groove is provided on the side of the ceramic thin plate. The back lining steel strip is bonded to the back of the ceramic thin plate, and both ends are bent backward along the thermal insulation board to form flanks. Corresponding socket heads and socket holes are provided on the flanks. An installation hole is also provided on one of the flanks and is connected to the transition angle code anchored on the base wall. A fastener is provided on the groove of the ceramic thin plate and fixed on the flank of the back lining steel strip. The thermal insulation board is bonded to the back of the ceramic thin plate. This installation structure solves the mechanical connection problem between the ceramic thin plate and the base wall in the application of the building exterior wall. However, this installation structure has many components and is complex to install. Moreover, the socket heads, socket holes and installation holes of the back lining steel strip are all formed and cannot be adjusted according to the actual situation during the on-site installation process. In addition, the fastener is connected to the back lining steel strip by screws, and the fasteners between adjacent two ceramic thin plates are separately separated. The support of the fastener to the ceramic thin plate is point support, resulting in a poor support effect of the fastener on the ceramic thin plate.

[0004] The prior art CN111206695A discloses an installation structure and installation method for a wall thermal insulation board. The installation structure includes an L-shaped adapter, a T-shaped guide rail, a T-shaped fixing piece, and a thermal insulation board. The L-shaped adapter includes a plane and a vertical surface that are perpendicular to each other. The column part of the T-shaped guide rail is provided with a one-way groove, and at least one of the two wings is provided with a groove. The vertical surface of the L-shaped adapter is fixed to the wall. The groove on the T-shaped guide rail catches the plane of the L-shaped adapter. A leveling layer is provided on the wall, and the thermal insulation board is installed outside the leveling layer. The column of the T-shaped fixing piece is inserted into the one-way groove of the T-shaped guide rail, and the two wings of the T-shaped fixing piece catch the groove opened at the edge of the surface layer of the thermal insulation board. This invention forms a columnar framework for installing the thermal insulation board through the combined connection of each component. Each component and the thermal insulation board can be prefabricated and do not need to be processed on site, greatly simplifying the installation process of the thermal insulation board and ensuring the quality at the same time. However, the T-shaped guide rail is installed above the L-shaped adapter, and the thicknesses of the T-shaped guide rail and the L-shaped connection piece are relatively thin. A card slot is also opened at the front end of the T-shaped guide rail. When the thermal insulation board is installed on the T-shaped guide rail, due to the large weight of the thermal insulation board, a large bending moment will be generated on the T-shaped guide rail. The above-mentioned bending moment will cause the T-shaped guide rail to disengage from the L-shaped adapter and even cause the T-shaped guide rail and the L-shaped adapter to break, still unable to well ensure the fixing safety of the thermal insulation board. Summary of the Invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide an installation structure and construction method for a ceramic thermal insulation composite board. The installation structure includes a first L-shaped angle iron, an L-shaped guide rail, a fixing clip, and a leveling layer. This installation structure has the advantages of ensuring the fixing safety of the ceramic thermal insulation composite board, having a simple structure, and improving the installation quality of the ceramic thermal insulation composite board.

[0006] To achieve the above invention purpose, the technical solutions adopted by the present invention are as follows:

[0007] An installation structure for a ceramic thermal insulation composite board, and the ceramic thermal insulation composite board is arranged on a base wall through the installation structure;

[0008] The installation structure includes a first L-shaped angle iron, an L-shaped guide rail, and a fixing clip. The first L-shaped angle iron is arranged on the base wall. The L-shaped guide rail is arranged at the bottom end of the first L-shaped angle iron, and the L-shaped guide rail is adjustably connected to the first L-shaped angle iron. An adjustment cushion block is arranged between the L-shaped guide rail and the base wall. The fixing clip is arranged at the front end of the L-shaped guide rail. A leveling layer is arranged on the surface of the base wall, and the first L-shaped angle iron and the L-shaped guide rail are embedded in the leveling layer.

[0009] Preferably, the first L-shaped angle iron includes a first vertical plate and a first horizontal plate. The first vertical plate is perpendicular to the first horizontal plate. The first vertical plate is connected to the base wall by anchor bolts. The first horizontal plate is arranged perpendicular to the base wall. The L-shaped guide rail is arranged at the bottom end of the first horizontal plate. By such an arrangement, the first vertical plate is connected to the base wall by anchor bolts, which can well ensure the stability of the connection between the first L-shaped angle iron and the base wall, and enable the L-shaped guide rail to adjust the relative position between it and the base wall.

[0010] Preferably, a straight slot hole is provided on the first vertical plate, and the length direction of the straight slot hole is perpendicular to the intersection line of the first vertical plate and the first horizontal plate. By such an arrangement, the first L-shaped angle iron is fixedly connected to the base wall by passing an anchor bolt through the straight slot hole. During the process of connecting with the anchor bolt, the first L-shaped angle iron can be adjusted along the length direction of the straight slot hole, so as to adjust the height position of the first L-shaped angle iron after being fixed to the base wall.

[0011] Preferably, the L-shaped guide rail includes a vertical rail and a horizontal rail. The vertical rail is perpendicular to the horizontal rail. The horizontal rail is arranged at the bottom end of the first horizontal plate, and the horizontal rail is adjustably connected to the first horizontal plate by self-tapping screws. By such an arrangement, since vertical control lines and horizontal control lines need to be set on the base wall when installing the ceramic thermal insulation composite board, the horizontal rail is adjustably connected to the first horizontal plate by self-tapping screws, so as to adjust the front end face of the L-shaped guide rail to be in the same plane as the vertical control lines and the horizontal control lines, ensuring the same flatness after the installation of the ceramic thermal insulation composite board and improving the installation quality of the ceramic thermal insulation composite board.

[0012] Preferably, the horizontal rail is provided with a hollow cavity, and a protrusion is provided at one end of the vertical rail away from the horizontal rail. By such an arrangement, the horizontal rail is provided with a hollow cavity. On the one hand, the weight can be reduced and the cost can be saved; on the other hand, it is equivalent to adding a reinforcing rib structure on the horizontal rail to improve the strength of the horizontal rail; and a protrusion is provided at one end of the vertical rail away from the horizontal rail, which improves the bending strength of the vertical rail without significantly increasing the weight of the L-shaped guide rail.

[0013] Preferably, the adjusting cushion block is arranged at one end of the vertical rail far away from the horizontal rail. By setting it in this way, the first L-shaped angle iron, the L-shaped guide rail and the fixing fixture are used to support the ceramic heat-insulating composite board. Since the ceramic heat-insulating composite board has a certain weight, the ceramic heat-insulating composite board will generate a bending moment on the first L-shaped angle iron and the L-shaped guide rail. After the first L-shaped angle iron adjusts the L-shaped guide rail, there will be a gap between the L-shaped guide rail and the base wall. The adjusting cushion block plays a supporting role for the L-shaped guide rail, avoiding the deformation of the L-shaped guide rail under the action of the above-mentioned bending moment. And the adjusting cushion block is arranged at one end of the vertical rail far away from the horizontal rail, so that the adjusting cushion block can better support the L-shaped guide rail.

[0014] Preferably, the leveling layer covers at least the vertical rail, and the distance between the surface of the leveling layer and the front end surface of the vertical rail is at least 10 mm. By setting it in this way, on the one hand, the leveling layer can improve the flatness of the installation base surface of the ceramic heat-insulating composite board, so that the special adhesive can better bond with the leveling layer and the ceramic heat-insulating composite board, improving the bonding stability of the ceramic heat-insulating composite board; on the other hand, the leveling layer can improve the firmness of the connection between the first L-shaped angle iron and the L-shaped guide rail, and the distance between the surface of the leveling layer and the front end surface of the vertical rail is at least 10 mm, which can ensure that the first L-shaped angle iron and the L-shaped guide rail have sufficient firmness.

[0015] Preferably, the distance between the surface of the leveling layer and the surface of the base wall is at least 20 mm. By setting it in this way, the leveling layer is bonded to the base wall as a whole through self-adhesion, and the distance between the surface of the leveling layer and the surface of the base is at least 20 mm, ensuring that the leveling layer has sufficient bonding strength.

[0016] Preferably, a one-way groove is provided on the front end surface of the L-shaped guide rail. The one-way groove is composed of a plurality of trapezoidal grooves. Along the depth direction of the one-way groove, the upper base of the trapezoidal groove is smaller than the lower base. The end of the fixing fixture is adapted to the one-way groove, and the end of the fixing fixture is embedded in the one-way groove. By setting it in this way, it is convenient for the installation of the fixing fixture, and the one-way groove has one-wayness. The end of the fixing fixture is easily embedded in the one-way groove, and it is difficult to pull out the fixing fixture after it is embedded in the one-way groove.

[0017] Preferably, the cross-sectional shape of the fixing clip is T-shaped. The fixing clip includes a cross bar and a vertical bar. One end of the cross bar is connected to the middle of the vertical bar, and the cross bar is perpendicular to the vertical bar. The other end of the cross bar is adapted to the one-way groove. With such a setting, when the fixing clip supports the ceramic heat-insulating composite board, the vertical bar abuts against the milled edge on the surface of the ceramic heat-insulating composite board. Since it is difficult to pull out the fixing clip after embedding, it plays a certain fixing role for the ceramic heat-insulating composite board and improves the safety and fixing performance of the ceramic heat-insulating composite board.

[0018] The construction method of the above installation structure includes the following steps:

[0019] Step 1: A plurality of the first L-shaped angle irons are provided on the base wall.

[0020] Step 2: A plurality of vertical control lines and horizontal control lines are set on the base wall.

[0021] Step 3: A plurality of L-shaped guide rails are provided on the base wall (7) at parallel intervals in the height direction. The L-shaped guide rails are arranged on the base wall through the first L-shaped angle irons, and the L-shaped guide rails are slidably adjusted relative to the first L-shaped angle irons so that the front end surfaces of the L-shaped guide rails are in the same plane as the vertical control lines and the horizontal control lines.

[0022] Step 4: After the L-shaped guide rails are adjusted, self-tapping screws are used to fixedly connect the L-shaped guide rails and the first L-shaped angle irons.

[0023] Step 5: Adjusting pads are arranged between the L-shaped guide rails and the base wall.

[0024] Step 6: Leveling mortar is smeared on the surface of the base wall, and the leveling mortar is leveled with a mortar leveling tool. After the leveling mortar solidifies, the leveling layer is formed.

[0025] Step 7: The fixing clip is embedded into the L-shaped guide rail.

[0026] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0027] 1. The adopted installation structure is simple and has few components. The first L-shaped angle iron, the L-shaped guide rail and the fixing clip are used to support the ceramic heat-insulating composite board in a line support manner. The leveling layer and the ceramic heat-insulating composite board are bonded by a special adhesive, and the fixing clip has a certain fixing effect on the ceramic heat-insulating composite board. The three force application methods of "adhesion, dragging and fixing" act on the ceramic heat-insulating composite board together to ensure the fixing safety of the ceramic heat-insulating composite board and avoid the situation of falling off.

[0028] 2. Since the ceramic thermal insulation composite panel has a certain weight, when the first L-shaped angle iron, the L-shaped guide rail and the fixing clip support the ceramic thermal insulation composite panel, the ceramic thermal insulation composite panel generates a bending moment on the first L-shaped angle iron and the L-shaped guide rail. Since an adjustment pad is provided between the L-shaped guide rail and the base wall, the adjustment pad supports the L-shaped guide rail and the first L-shaped angle iron to avoid deformation of the first L-shaped angle iron and the L-shaped guide rail under the action of the bending moment. In addition, the L-shaped guide rail has sufficient strength to avoid breakage, thereby further improving the fixing safety of the ceramic thermal insulation composite panel.

[0029] 3. When installing the ceramic thermal insulation composite panel, after the position of the L-shaped guide rail is adjusted relative to the first L-shaped angle iron, the front end surface of the L-shaped guide rail is in the same plane as the vertical control line and the horizontal control line, thereby ensuring the uniform flatness of the ceramic thermal insulation composite panel after installation and improving the installation quality of the ceramic thermal insulation composite panel.

DETAILED DESCRIPTION

[0036] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with embodiments. However, the scope of protection required by the present invention is not limited to the specific embodiments below.

[0037] Refer to Figure 1 , this embodiment discloses an installation structure for a ceramic thermal insulation composite board. The ceramic thermal insulation composite board is arranged on a base wall 7 through the installation structure;

[0038] The installation structure includes a first L-shaped angle iron 1, an L-shaped guide rail 2 and a fixing clip 3. The first L-shaped angle iron 1 is arranged on the base wall 7. The L-shaped guide rail 2 is arranged at the bottom end of the first L-shaped angle iron 1, and the L-shaped guide rail 2 is adjustably connected to the first L-shaped angle iron 1. An adjustment cushion block 5 is arranged between the L-shaped guide rail 2 and the base wall 7. The adjustment cushion block 5 abuts against the L-shaped guide rail 2 and the base wall 7 respectively. The fixing clip 3 is arranged at the front end of the L-shaped guide rail 2. A leveling layer 8 is arranged on the surface of the base wall 7. The leveling layer 8 is composed of low-alkalinity cement mortar or plastering leveling mortar. Part of the structures of the first L-shaped angle iron 1 and the L-shaped guide rail 2 are embedded in the leveling layer 8. The aforementioned front end refers to the end far from the base wall 7, and the end close to the base wall 7 is the rear end. The meanings of the front end and the rear end mentioned below are the same.

[0039] The above-mentioned installation structure is simple, with few components. And the first L-shaped angle iron 1, the L-shaped guide rail 2 and the fixing clip 3 are used to support the ceramic thermal insulation composite board in a wire support manner. The ceramic thermal insulation composite board and the leveling layer 8 are bonded by a special adhesive, and the fixing clip 3 has a certain fixing effect on the ceramic thermal insulation composite board. The three force application methods of "adhesion, dragging and fixing" act on the ceramic thermal insulation composite board together to ensure the fixing safety of the ceramic thermal insulation composite board and avoid the situation of falling off; due to the certain weight of the ceramic thermal insulation composite board, when the first L-shaped angle iron 1, the L-shaped guide rail 2 and the fixing clip 3 support the ceramic thermal insulation composite board, the ceramic thermal insulation composite board generates a bending moment on the first L-shaped angle iron 1 and the L-shaped guide rail 2. Since the L-shaped guide rail 2 is arranged at the bottom end of the first L-shaped angle iron 1, and the adjustment cushion block 5 is arranged between the L-shaped guide rail 2 and the base wall 7, the adjustment cushion block 5 supports the L-shaped guide rail 2 and the first L-shaped angle iron 1, avoiding deformation of the first L-shaped angle iron 1 and the L-shaped guide rail 2 under the action of the bending moment, and the L-shaped guide rail 2 has sufficient strength to avoid the situation of fracture, further improving the fixing safety of the ceramic thermal insulation composite board; when installing the ceramic thermal insulation composite board, after the L-shaped guide rail 2 is adjusted in position relative to the first L-shaped angle iron 1, the front end face of the L-shaped guide rail 2 is made to be in the same plane as the vertical control line and the horizontal control line, ensuring the consistency of the flatness after the installation of the ceramic thermal insulation composite board and improving the installation quality of the ceramic thermal insulation composite board.

[0040] The first L-shaped angle iron 1 includes a first vertical plate 1.2 and a first horizontal plate 1.1. The first vertical plate 1.2 and the first horizontal plate 1.1 are integrally formed, and the first vertical plate 1.2 and the first horizontal plate 1.1 are perpendicular to each other. The first vertical plate 1.2 is connected to the base wall 7 by anchor bolts. The anchor bolt method between the first vertical plate 1.2 and the base wall 7 includes one of the methods of metal expansion anchor bolts 6, chemical anchor bolts, internal forced expansion bolt anchors or back-twisting and knotting type anchor bolts. Specifically, in this embodiment, the anchor bolt method between the first vertical plate 1.2 and the base wall 7 uses metal expansion anchor bolts 6. This anchor bolt method is simple, firm and low in cost. The first horizontal plate 1.1 is arranged perpendicular to the base wall 7. The L-shaped guide rail 2 is arranged at the bottom end of the first horizontal plate 1.1. The first vertical plate 1.2 is connected to the base wall 7 by anchor bolts, which can well ensure the stability of the connection between the first L-shaped angle iron 1 and the base wall 7, and enable the L-shaped guide rail 2 to adjust the relative position with the base wall 7.

[0041] Straight groove holes are provided on the first vertical plate 1.2, and the length direction of the straight groove holes is perpendicular to the intersection line of the first vertical plate 1.2 and the first horizontal plate 1.1. Anchor bolts are used to pass through the straight groove holes to fixedly connect the first L-shaped angle iron 1 and the base wall 7. During the process of using anchor bolts for connection, the first L-shaped angle iron 1 can be adjusted along the length direction of the straight groove holes, so as to adjust the height position of the first L-shaped angle iron 1 after being fixed to the base wall 7.

[0042] The L-shaped guide rail 2 includes a vertical rail 2.2 and a horizontal rail 2.1. The vertical rail 2.2 and the horizontal rail 2.1 are integrally formed, and the vertical rail 2.2 and the horizontal rail 2.1 are perpendicular to each other. The horizontal rail 2.1 is arranged at the bottom end of the first horizontal plate 1.1, and the horizontal rail 2.1 and the first horizontal plate 1.1 are adjusted and connected by self-tapping screws 4 to realize the sliding adjustment of the L-shaped guide rail 2 and the first L-shaped angle iron 1. Since vertical control lines and horizontal control lines need to be set on the base wall 7 when installing the ceramic thermal insulation composite board, the horizontal rail 2.1 and the first horizontal plate 1.1 are adjusted and connected by self-tapping screws 4, so as to adjust the front end face of the L-shaped guide rail 2 to be in the same plane as the vertical control lines and the horizontal control lines. The adjustment method of the horizontal rail 2.1 and the first horizontal plate 1.1 is: the horizontal rail 2.1 slides and adjusts along the direction perpendicular to the base wall 7 at the bottom end of the first horizontal plate 1.1. When the front end face of the L-shaped guide rail 2 is in the same plane as the vertical control lines and the horizontal control lines, self-tapping screws 4 are screwed into the horizontal rail 2.1 and the first horizontal plate 1.1 to ensure the same flatness after the installation of the ceramic thermal insulation composite board and improve the installation quality of the ceramic thermal insulation composite board.

[0043] The horizontal rail 2.1 is provided with a hollow cavity 2.3 inside. On the one hand, it can reduce the weight and save costs; on the other hand, it is equivalent to adding a reinforcing rib structure on the horizontal rail 2.1, improving the strength of the horizontal rail 2.1; and a protrusion is provided at one end of the vertical rail 2.2 away from the horizontal rail 2.1, which improves the bending strength of the vertical rail 2.2 without significantly increasing the weight of the L-shaped guide rail 2.

[0044] The adjusting cushion block 5 is arranged at one end of the vertical rail 2.2 far away from the horizontal rail 2.1. The first L-shaped angle iron 1, the L-shaped guide rail 2 and the fixing fixture 3 are used to support the ceramic heat-insulating composite board. Since the ceramic heat-insulating composite board has a certain weight, the ceramic heat-insulating composite board will generate a bending moment on the first L-shaped angle iron 1 and the L-shaped guide rail 2. After the L-shaped guide rail 2 is adjusted on the first L-shaped angle iron 1, there will be a gap between the L-shaped guide rail 2 and the base wall 7. The adjusting cushion block 5 plays a supporting role for the L-shaped guide rail 2 to prevent the L-shaped guide rail 2 from deforming under the action of the above-mentioned bending moment. And the adjusting cushion block 5 is arranged at one end of the vertical rail 2.2 far away from the horizontal rail 2.1. According to the force analysis, the adjusting cushion block 5 can better support the L-shaped guide rail 2.

[0045] The leveling layer 8 covers at least the vertical rail 2.2, and the distance a between the surface of the leveling layer 8 and the front end face of the vertical rail 2.2 is at least 10 mm. On the one hand, the provision of the leveling layer 8 can improve the flatness of the installation base surface of the ceramic heat-insulating composite board, so that the special adhesive can better bond with the leveling layer 8 and the ceramic heat-insulating composite board, improving the bonding stability of the ceramic heat-insulating composite board. If the ceramic heat-insulating composite board is directly bonded to the base wall 7 with the special adhesive, due to the poor flatness of the base wall 7, when the ceramic heat-insulating composite board is bonded to the base wall 7, the special adhesive cannot completely bond with the base wall 7 and the ceramic heat-insulating composite board, that is, there is a gap between the ceramic heat-insulating composite board and the base wall 7, reducing the bonding stability of the ceramic heat-insulating composite board. On the other hand, the provision of the leveling layer 8 can improve the firmness of the connection between the first L-shaped angle iron 1 and the L-shaped guide rail 2, and the distance a between the surface of the leveling layer 8 and the front end face of the vertical rail 2.2 is at least 10 mm, which can ensure that the first L-shaped angle iron 1 and the L-shaped guide rail 2 have sufficient firmness.

[0046] The distance b between the surface of the leveling layer 8 and the surface of the base wall 7 is at least 20 mm. The leveling layer 8 is bonded to the base wall 7 as a whole through self-adhesion, and the leveling layer 8 is also formed as a whole through self-adhesion inside. The distance b between the surface of the leveling layer 8 and the surface of the base wall 7 is at least 20 mm, ensuring that the leveling layer 8 has sufficient bonding strength.

[0047] A one-way groove 2.4 is provided on the front end face of the L-shaped guide rail 2. The one-way groove 2.4 is composed of a plurality of identical trapezoidal grooves. Along the depth direction of the one-way groove 2.4, the upper base of the trapezoidal groove is smaller than the lower base. Refer to Figure 1 , between two adjacent trapezoidal grooves, the lower base of the left trapezoidal groove is connected to the upper base of the right trapezoidal groove. The end of the fixing fixture 3 is adapted to the one-way groove 2.4, and the end of the fixing fixture 3 is embedded in the one-way groove 2.4, facilitating the installation of the fixing fixture 3. And the one-way groove 2.4 has one-wayness. The end of the fixing fixture 3 is easily embedded in the one-way groove 2.4, and it is difficult to pull out the fixing fixture 3 after it is embedded in the one-way groove 2.4.

[0048] The fixing clip 3 is equal in length to the L-shaped guide rail 2, so as to support the ceramic thermal insulation composite board in a line support manner. The cross-sectional shape of the fixing clip 3 is T-shaped. The fixing clip 3 includes a cross bar 3.1 and a vertical bar 3.2. The vertical bar 3.2 is integrally formed with the cross bar 3.1. One end of the cross bar 3.1 is connected to the middle of the vertical bar 3.2, and the vertical bar 3.2 is perpendicular to the cross bar 3.1. The other end of the cross bar 3.1 is adapted to the one-way groove 2.4. When the fixing clip 3 supports the ceramic thermal insulation composite board, the vertical bar 3.2 abuts against the milled edge on the surface of the ceramic thermal insulation composite board. Since it is difficult to pull out the fixing clip 3 after it is inserted, it plays a certain fixing role on the ceramic thermal insulation composite board, improves the safety fixing of the ceramic thermal insulation composite board, and makes the fixing clips 3 of two adjacent ceramic thermal insulation composite boards up and down integrated, improving the support and fixing effect of the fixing clip.

[0049] The construction method of the installation structure of the embodiment of the present invention includes the following steps:

[0050] Step 1: A plurality of first L-shaped angle irons 1 are provided on the base wall 7. Specifically, the first vertical plate 1.2 of the first L-shaped angle iron 1 is connected to the base wall 7 through metal expansion anchor bolts 6. And during the connection of the anchor bolts, the first L-shaped angle iron 1 is adjusted along the length direction of the straight slot hole, so that the first horizontal plate 1.1 of the first L-shaped angle iron 1 remains horizontal, and the distance between two adjacent first L-shaped angle irons 1 up and down is equal to the height of the ceramic thermal insulation composite board to be installed;

[0051] Step 2: A plurality of vertical control lines and horizontal control lines are provided on the base wall 7, and the vertical control lines and the horizontal control lines are in the same plane;

[0052] Step 3: A plurality of L-shaped guide rails 2 are provided on the base wall 7 at parallel intervals along the height direction. The L-shaped guide rails 2 are arranged on the base wall 7 through the first L-shaped angle irons 1, and the L-shaped guide rails 2 are slidably adjusted relative to the first L-shaped angle irons. Specifically, the cross rail 2.1 is abutted below the first horizontal plate 1.1, and the cross rail 2.1 is slidably adjusted along the direction perpendicular to the base wall 7, so that the front end surface of the L-shaped guide rail 2 is in the same plane as the vertical control line and the horizontal control line;

[0053] Step 4: After the first L-shaped angle iron 1 is adjusted, self-tapping screws 4 are screwed into the first horizontal plate 1.1 and the cross rail 2.1 to fixedly connect the first L-shaped angle iron 1 and the L-shaped guide rail 2;

[0054] Step 5: Adjustment pads 5 are arranged between the vertical rail 2.2 and the base wall 7, and the adjustment pads 5 are arranged at one end of the vertical rail 2.2 away from the cross rail 2.1. The adjustment pads 5 are in close contact with the base wall 7 and the vertical rail 2.2;

[0055] Step 6: Apply leveling mortar on the surface of the base wall 7, and use a mortar leveling tool to level the leveling mortar. After the leveling mortar dries, a leveling layer 8 is formed. Specifically, referring to Figure 2 , the mortar leveling tool includes a pressure roller 9, a control slider 10 and a handle 11; the handle 11 is arranged on the pressure roller 9, control sliders 10 are provided at both ends of the pressure roller 9, the handle 11 is located between the control sliders 10 at both ends, the control slider 10 is slidably connected to the pressure roller 9, the control slider 10 includes a supporting portion 10.1 that abuts against the L-shaped guide rail 2, the cross-sectional shapes of the supporting portion 10.1 and the pressure roller 9 are both semi-circular, and the axis of the supporting portion 10.1 is parallel to the axis of the pressure roller 9. When constructing with the above-mentioned mortar leveling tool, the supporting portion 10.1 abuts against the L-shaped guide rail 2 for support and positioning. When the mortar leveling tool is slid along the length direction of the L-shaped guide rail 2, the pressure roller 9 compacts and levels the mortar, ensuring that the leveling layer 8 has high flatness, high leveling quality and high leveling efficiency. Since the cross-sectional shapes of the supporting portion 10.1 and the pressure roller 9 are both semi-circular, and the axis of the supporting portion 10.1 is parallel to the axis of the pressure roller 9, even when rotating around the axis of the supporting portion 10.1 or the pressure roller 9 during the sliding process, the flatness of the leveling layer 8 can still be ensured, thereby ensuring the construction quality of the ceramic thermal insulation composite board;

[0056] Step 7: Insert one end of the fixing clip 3 into the one-way groove 2.4 of the L-shaped guide rail 2.

[0057] For further specific description, referring to Figure 2-4 , the ratio of the radius of the supporting portion 10.1 to the radius of the pressure roller 9 is between 1:4 and 1:2, that is, the radius of the supporting portion 10.1 is 2 - 4 times smaller than the radius of the pressure roller 9. Since the supporting portion 10.1 only needs to abut against the L-shaped guide rail 2 to play a role in support and positioning, the volume of the supporting portion 10.1 does not need to be set too large. On the one hand, the quality of the mortar leveling tool can be reduced; on the other hand, the amount of production materials can be reduced, and the production cost can be lowered.

[0058] The pressing roller 9 includes a first arc surface 9.2 for smoothing the mortar and a first flat surface 9.1. The supporting part 10.1 includes a second arc surface 10.1.2 in contact with the L-shaped guide rail 2 and a second flat surface 10.1.1. The first flat surface 9.1 and the second flat surface 10.1.1 are arranged in parallel. When using the mortar smoothing tool to smooth the mortar, the second arc surface 10.1.2 of the supporting part 10.1 abuts against the L-shaped guide rail 2, and the mortar is compacted and smoothed by the first arc surface 9.2 of the pressing roller 9. The cross-sectional shapes of the supporting part 10.1 and the pressing roller 9 are both semi-circular, that is, the radii of the points on the first arc surface 9.2 are equal and the radii of the points on the second arc surface 10.1.2 are equal. During the process of smoothing the mortar, even when rotating around the axis of the pressing roller 9 or the supporting part 10.1, the flatness of the leveling layer 8 can still be ensured. Moreover, since the first flat surface 9.1 and the second flat surface 10.1.1 are arranged in parallel, it can be ensured that the allowable rotation angles of the supporting part 10.1 and the pressing roller 9 are equal.

[0059] Second L-shaped angle irons 12 are provided at both ends of the pressing roller 9. The second L-shaped angle iron 12 includes a second horizontal plate 12.2 and a second vertical plate 12.1. The second horizontal plate 12.2 and the second vertical plate 12.1 are perpendicularly arranged. The second horizontal plate 12.2 is arranged on the first flat surface 9.1 and connected to the pressing roller 9. A first long hole 12.1.1 is provided on the second vertical plate 12.1, and the length direction of the first long hole 12.1.1 is perpendicular to the first flat surface 9.1. The control slider 10 further includes a connecting part 10.2 connected to the second L-shaped angle iron 12. The connecting part 10.2 and the supporting part 10.1 are connected by welding. The connecting part 10.2 is provided with a through hole corresponding to the first long hole 12.1.1, and the connecting part 10.2 is adjustably connected to the second L-shaped angle iron 12 through the first long hole 12.1.1. The specific adjustment method is as follows: Bolts are sequentially passed through the through hole and the first long hole 12.1.1 and then threadedly connected to the fixing nuts. According to the thickness requirement of the leveling layer 8, the connecting part 10.2 is slid and adjusted along the direction of the first long hole 12.1.1, that is, the distance between the first flat surface 9.1 and the second flat surface 10.1.1 is adjusted until when the supporting part 10.1 abuts against the L-shaped guide rail 2, the closest distance between the first arc surface 9.2 and the base wall 7 is equal to the required thickness of the leveling layer 8, and then the bolts are tightened with the fixing nuts.

[0060] There are two first elongated holes 12.1.1 provided on the second vertical plate 12.1. The two first elongated holes 12.1.1 are arranged in parallel at intervals along the length direction of the pressure roller 9. The connecting parts 10.2 are respectively provided with the through holes corresponding to the two first elongated holes 12.1.1 one by one. During the process of the connecting part 10.2 adjusting along the first elongated hole 12.1.1, it is ensured that the first plane 9.1 and the second plane 10.1.1 are always parallel to each other; if there is only one first elongated hole 12.1.1 provided on the second vertical plate 12.1, during the process of the connecting part 10.2 adjusting along the first elongated hole 12.1.1, it is easy for the control slider 10 to rotate around the direction of the bolt, then the first plane 9.1 and the second plane 10.1.1 still need to be adjusted to ensure parallelism with each other, making the adjustment cumbersome.

[0061] The cross-sectional shape of the connecting part 10.2 is L-shaped. The connecting part 10.2 includes a third vertical plate 10.2.1 and a third horizontal plate 10.2.2. The third vertical plate 10.2.1 and the third horizontal plate 10.2.2 are perpendicularly arranged. The through hole is provided on the third vertical plate 10.2.1. The third vertical plate 10.2.1 is connected to the second vertical plate 12.1. The third horizontal plate 10.2.2 is arranged parallel to the second plane 10.1.1. Since the second vertical plate 12.1 and the second horizontal plate 12.2 are perpendicularly arranged, the second horizontal plate 12.2 is arranged on the first plane 9.1 and connected to the pressure roller 9. The third vertical plate 10.2.1 and the third horizontal plate 10.2.2 are perpendicularly arranged. The third vertical plate 10.2.1 is connected to the second vertical plate 12.1 through two first elongated holes 12.1.1. The third horizontal plate 10.2.2 is arranged parallel to the second plane 10.1.1. It can be known that after the control slider 10 is connected to the second L-shaped angle iron 12, the parallelism between the first plane 9.1 and the second plane 10.1.1 can be ensured.

[0062] The axis of the supporting part 10.1 is located on the side surface where the third vertical plate 10.2.1 abuts against the second L-shaped angle iron 12. When the end surface of the supporting part 10.1 facing the handle 11 abuts against the second L-shaped angle iron 12, the through hole is opposite to the corresponding first elongated hole 12.1.1, which is convenient for positioning when the control slider 10 is connected to the second L-shaped angle iron 12.

[0063] There is a second elongated hole provided on the second horizontal plate 12.2. The length direction of the second elongated hole is perpendicularly arranged to the length direction of the first elongated hole 12.1.1. There is a threaded hole corresponding to the second elongated hole provided on the pressure roller 9. The second L-shaped angle iron 12 is adjustably connected to the pressure roller 9 through the second elongated hole. The specific adjustment method is as follows: A screw is used to pass through the second elongated hole and be threadedly connected to the threaded hole. The second L-shaped angle iron 12 moves and adjusts along the length direction of the second elongated hole, so that the position of the control slider 10 can be adjusted. After the adjustment is completed, the screw is tightened.

[0064] There are two second long holes provided on the second transverse plate 12.2. The two second long holes are arranged in parallel at intervals along the length direction of the pressure roller 9. The pressure roller 9 is respectively provided with the threaded holes corresponding to the two second long holes one by one, ensuring that the second L-shaped angle iron 12 is always adjusted along the length direction of the second long hole.

[0065] A handle mounting seat 13 is provided on the pressure roller 9. The handle mounting seat 13 includes a fourth transverse plate 13.2 and fourth vertical plates 13.1 arranged at both ends of the fourth transverse plate 13.2. The fourth vertical plates 13.1 at both ends are arranged parallel to each other. The fourth transverse plate 13.2 is arranged on the first plane 9.1 and fixedly connected to the pressure roller 9 by screws. The handle 11 is in a cylindrical shape. Both ends of the handle 11 are fixedly connected to the fourth vertical plates 13.1 located at both ends of the fourth transverse plate 13.2, facilitating the construction personnel to hold the mortar smoothing tool for construction.
