[0001] The present invention relates to the technical field of thermal insulation, and particularly to a construction process for a composite thermal insulation board. Background Art

[0002] Thermal insulation boards are widely used in the thermal insulation projects of walls. In the prior art, vacuum insulation panels are directly used as thermal insulation boards, but the breakage rate is extremely high; when a vacuum panel is combined with a thermal insulation slurry protective layer, although the breakage rate is reduced, the thermal insulation effects of the two materials are very different, cold bridge phenomena are likely to occur, the design correction coefficient is large, and the overall performance is poor, resulting in limited application of the product; it is difficult for traditional extruded polystyrene boards to be used alone to meet the increasingly high energy-saving requirements. Therefore, when conventional composite thermal insulation boards are used for wall thermal insulation construction, there are many problems, and the application scenarios of conventional composite thermal insulation boards are single, which cannot meet the diverse construction needs.

The upper clamping plate slides upward in the cavity opened in the lower clamping plate, and the guiding shaft slides upward in the guiding groove. When the upper clamping plate slides out of the lower clamping plate upward, at this time, the guiding shaft of the lower clamping plate slides into the horizontal guiding groove along the vertical guiding groove; S3: As the guiding shaft slides in the vertical guiding groove, the two upper clamping plates move away from each other. At the same time, the upper clamping plate drives the sliding shaft to slide in the arc-shaped sliding groove through the connecting rod. When the sliding shaft slides from the arc-shaped sliding groove into the horizontal sliding groove, the sliding shaft will continue to slide into the horizontal sliding groove; S4: As the two upper clamping plates continue to move away from each other, finally, the two upper clamping plates respectively fit against the inner surface of the upper clamping groove, and at the same time, the upper surface of the limiting member located at the uppermost part is flush with the upper surface of the upper clamping plate, thereby realizing the connection of the four composite insulation boards.

Detailed description of the specific implementation

[0019] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0020] Embodiment 1 As Figures 1 - 2 , Figures 4 - 10As shown in the figure, this embodiment proposes a construction technology for a composite insulation board. According to the design requirements, the extruded polystyrene board 2 is cut by equipment or manually, and at least one vacuum insulation panel 3 is bonded to the extruded polystyrene board 2 with a special adhesive mortar, and then further strengthened and bonded by a press.

[0021] The bonded insulation board is placed into the composite slurry production line, and the insulation slurry 1 is wrapped around the periphery of the vacuum insulation panel 3 to isolate the vacuum insulation panel 3 from the outside. The vacuum insulation panel 3 is located between the extruded polystyrene board 2 and the insulation slurry 1, thereby forming a composite insulation board by compounding. The extruded polystyrene board 2 can be replaced with insulation materials such as polystyrene board and PU board.

[0022] Embedded parts are buried in the insulation slurry 1. The embedded parts are steel wire mesh 11, galvanized electric welding mesh or mesh cloth. When strengthening measures such as mesh cloth, galvanized electric welding mesh or steel wire mesh 11 are carried out in the insulation slurry 1, they are all compounded and formed with the insulation board by the composite slurry production line.

[0023] The composite insulation board with a single vacuum insulation panel 3 is applied to the thermal insulation construction of the wall. After the main building is completed, thermal insulation construction is carried out by bonding mortar and drilling holes in the wall to embed special thermal insulation connection anchors. After the thermal insulation construction is completed, subsequent processes such as leveling and decorative layer are carried out.

[0024] Or the bonded decorative layer 10 is applied to the integrated exterior wall thermal insulation and decoration construction. The construction method of the integrated thermal insulation and decoration board is a combination of bonding and hanging. In this process, connectors 5 can be used, or thermal break components, such as glass fiber materials or metal thermal break components.

[0025] The composite insulation board with multiple vacuum insulation panels 3 is applied to the external formwork construction. During the construction, the composite insulation board is used to replace the external formwork for construction. After the steel bars are tied, the composite insulation board is erected on the outer sides of shear walls, beam columns, and professional connection anchors are installed, and the traditional building construction method is used to reinforce the external thermal insulation and the internal formwork for concrete pouring.

[0026] Or the prefabricated exterior wall construction, one is the sandwich exterior wall construction. The construction process: first construct one side of the wall, first complete the construction of the external concrete leaf wall or the internal concrete leaf wall. The external and internal concrete leaf walls are generally made of reinforced concrete materials; place the composite insulation board and the connector 5 on the side of the wall that has been constructed; construct the remaining wall to complete the construction of the remaining unconstructed side of the wall, so that the composite insulation board is sandwiched between two layers of concrete walls, forming a sandwich-like structural form.

[0027] When adopting this method, it has good heat preservation performance: the composite heat preservation board is sandwiched between two layers of concrete wall panels, enhancing the heat preservation and energy-saving performance of the exterior wall. It has strong durability: this structure can make the heat preservation have the same service life as the building, reducing the maintenance cost of the exterior wall. It has good fire resistance: to a certain extent, it reduces the fire risk of the exterior wall.

[0028] The second is the construction of the sandwich exterior wall. The construction process: Place the composite heat preservation board and the connecting piece 5. First, place the composite heat preservation board and the connecting piece 5 in the wall formwork. Construct the inner leaf wall. After the placement of the composite heat preservation board and the connecting piece 5 is completed, carry out the construction operation of the inner leaf wall. The inner leaf wall is a stressed concrete wall, generally equipped with a double-layer stressed steel mesh. Leveling after capping: After the wall panel is applied to the construction project and capped, level it with 10-20 mm thick non-combustible heat preservation mortar.

[0029] When adopting this method, it has a simple structure: the construction process is relatively simple, easy to operate, good heat preservation effect: the composite heat preservation board is closely combined with the wall, with a good heat preservation effect, and high construction efficiency. During on-site construction, cumbersome processes such as formwork support are eliminated, improving the construction efficiency.

[0030] The cooperation of the vacuum insulation board 3, the extruded polystyrene board 2 and the heat preservation slurry 1 can be realized by pouring or bonding or other methods. The vacuum insulation board 3 is located between the extruded polystyrene board 2 and the heat preservation slurry 1, and the heat preservation slurry 1 wraps the vacuum insulation board 3 so as to isolate the vacuum insulation board 3 from the outside.

[0031] Using the extruded polystyrene board 2 composite vacuum insulation board 3 as the core material greatly improves the heat preservation effect of the material. The heat preservation slurry 1 arranged on the outside improves the overall performance of the heat preservation material and also better protects the vacuum insulation board 3. Using the extruded polystyrene board 2 with good heat preservation effect as the bottom plate greatly reduces the cold bridge effect and improves the overall heat preservation performance.

[0032] The extruded polystyrene board 2 and the heat preservation slurry 1 are arranged in a staggered manner. One end of the extruded polystyrene board 2 forms a recess inward, and the other end of the extruded polystyrene board 2 forms a protrusion that fits with the adjacent recess, so as to realize the fitting between the construction processes of two adjacent composite heat preservation boards and the assembly of the construction processes of adjacent composite heat preservation boards. By adopting this method, the construction processes of adjacent composite heat preservation boards can be aligned to form a complete heat preservation wall.

[0033] A plurality of vacuum insulation boards 3 are attached to one extruded polystyrene board 2 as the base material. There is a gap between adjacent vacuum insulation boards 3, and the gap is filled with heat preservation slurry 1. The heat preservation slurry 1 wraps a plurality of vacuum insulation boards 3 to better protect the vacuum insulation boards 3. The heat preservation slurry 1 adopts a special non-combustible material.

[0034] There is a decorative layer 10 attached to the outside of the thermal insulation mortar 1. The decorative layer 10 can be an aluminum single plate, a ceramic thin plate, a rock slab, a real stone paint, etc. The decorative layer 10 also has the function of heat preservation. The decorative layer 10 is formed in one step, which can save the construction period and solve the problem of difficult realization of diversified building facades.

[0035] By using the extruded polystyrene board 2 as the backboard and the vacuum insulation panel 1 as the core material, the heat preservation effect of the board is greatly improved, the cold bridge is reduced, and the energy-saving design correction coefficient can be greatly reduced, from the traditional 1.25 - 1.5 to 1.05 - 1.15.

[0036] In terms of integrity, in the traditional form of mortar wrapping the vacuum panel, the vacuum panel is in discontinuous blocks, and only the wrapping mortar provides strength, so the integrity is poor. The overall flexural resistance effect barely meets the current national standard. However, in this application, with the excellent integrity of the extruded polystyrene board 2 itself, combined with the outer protective layer, the integrity of the board is better, and the overall flexural resistance effect can exceed the current standard by more than 50%.

[0037] In addition, the thickness of the outer thermal insulation mortar 1 is 20 - 30 mm, the thickness of the extruded polystyrene board 2 is 30 - 50 mm, and the thickness of the vacuum insulation panel 3 is designed according to the energy-saving design requirements, which can meet the design and construction requirements of various conventional building projects, low-energy consumption projects, passive house projects, low-carbon, nearly zero-carbon, zero-carbon building projects, and special demand projects in extremely cold and extremely hot regions, etc.

[0038] It also includes a connector 5 that can be inserted into the embedded hole of the extruded polystyrene board 2. A through hole 52 for a tie bolt 9 or other tie members to pass through is provided in the connector 5. Since the connector 5 can be inserted into the embedded hole of the extruded polystyrene board 2, the connector 5 can be used to connect the extruded polystyrene board 2 and the vacuum insulation panel 3, without the need for additional subsequent hole opening, which is convenient for subsequent assembly and forming.

[0039] On both sides of the connector 5, there are respectively a pair of fixing plates 54. The two pairs of fixing plates 54 are symmetrically arranged along the connector 5. A pair of fixing plates 54 and the connector 5 form a vacuum panel slot 55 for the vacuum insulation panel 3 to be embedded. A total of four fixing plates 54 are provided for one connector 5. The fixing plates 54 and the connector 5 can be integrally cast and formed, so as to realize the connection work of the vacuum insulation panels 3 on both sides.

[0040] A steel wire mesh 11 is embedded in the thermal insulation mortar 1. The connector 5 is provided with a clamping hole 51 that can clamp the steel wire mesh 11. The steel wire mesh 11 can be replaced with a galvanized electric welding net or a mesh cloth, so as to strengthen the overall strength of the thermal insulation mortar 1 and increase the overall flexural resistance. One side of the connector 5 protrudes outward and can be anchored into the concrete, so that when the insulation board is used as an external formwork, it can play a certain role in protection and connection.

[0041] The connecting member 5 is connected with a support plate 4 that can fit against the extruded polystyrene board 2. An internal thread 41 is provided on the inner side of the support plate 4. The outer side of the connecting member 5 is provided with an external thread 53 in the form of threading, so as to realize the threaded connection between the support plate 4 and the connecting member 5. The cross section of the support plate 4 is circular or polygonal, and the support plate 4 realizes the support of the extruded polystyrene board 2.

[0042] The integrated construction of exterior wall thermal insulation and decoration includes the following steps: S11: Perform the treatment of the wall base layer. Check whether the plaster layer on the base wall is flat and firm. There should be no hollowing or cracking on the wall surface. The chipped layer should be chiseled off first and filled with high-strength cement mortar. Perform the construction of the wall reference line. First, pop the horizontal connection lines around the building, and then hang vertical lines at the external corners of the building to release vertical lines as the reference lines. At the same time, pop the vertical control lines for each column and the horizontal control lines for each floor from bottom to top to control the verticality and horizontality of the paving of the integrated thermal insulation and decoration board. Both the horizontal line and the vertical line should be popped with double control lines according to the board joint width. Based on the layout drawing, use the position of the fixing parts between the control lines to punch expansion bolt holes based on the reference line. S12: Install the composite thermal insulation board. Install the connecting member 5 of the composite thermal insulation board into the expansion bolt hole, and prepare the bonding mortar. The mixing ratio of the bonding mortar is: powder: glue: water = 10: 1.5: 1.7 - 2. First, add water to the glue, stir evenly, and then add the powder while stirring (using an electric stirrer) until the slurry can be smoothly scraped and does not flow down. Roll the interface agent on the back of the composite thermal insulation board. S13: Apply the bonding mortar around and in the middle of the composite thermal insulation board. The bonding mortar in the middle part can be in a circular shape. The total area of the bonding mortar should not be less than 50% of the area of the integrated board. Use a combination of strip bonding method and dot bonding method to paste the composite thermal insulation board. Hold the suction cup to adjust the flatness of the board surface and the grid size. Use a straightedge and a plumb bob to check the flatness and verticality, and adjust the relative flatness of adjacent boards and the board joint width. When the board surface is significantly lower than the flatness reference surface due to excessive pressing, the board should be lifted, the original bonding mortar should be scraped off, and then the bonding mortar should be scraped and pasted again. After that, screw the tie bolt 9 into the through hole 52 of the connecting member 5 to anchor the composite thermal insulation board to the wall base layer. S14: Insert a foam strip into the gap between adjacent composite thermal insulation boards, inject glue and install an exhaust plug. To ensure the thermal insulation effect at the board joints, foam strips are embedded at the board joints, and the filling height should be 8-10 mm lower than the surface of the integral board. Then, silicone weatherproof sealant is injected. The surface of the sealant joint should be flat and smooth, and the capping, edging, and bottom sealing should be firm and beautiful, and water seepage is strictly prohibited. The surface of the silicone weatherproof sealant should be 1-2 mm lower than the surface of the board. After the silicone weatherproof sealant has cured for 24 hours, the exhaust plugs are embedded at intervals of 5 m - 8 m in the cross joints of the boards or in the middle of the joints between two boards. The exhaust holes of the exhaust plugs should face downwards, and the exhaust holes are strictly prohibited from being blocked. Then, self-inspection and repair are carried out.

[0043] Embodiment 2 Reference appendix Figure 3 、 Figures 11 - 16 In this embodiment, the thermal insulation slurry 1 and the extruded polystyrene board 2 are provided with card slots. Four adjacent card slots form a space for accommodating one card board. One card board can connect four low-energy composite insulation boards at the same time. The four low-energy composite insulation boards are specifically two on the upper side and two on the lower side. The four low-energy composite insulation boards can be combined to form a complete thermal insulation wall.

[0044] The two card slots located below are lower card slots, and the two card slots located above are upper card slots. The card board includes an upper card board 7 adapted to the upper card slot and a lower card board 6 adapted to the lower card slot. The card board has two setting methods. Method 1: The surface of the card board is arranged parallel to the extruded polystyrene board 2, which can make the extruded polystyrene boards 2 on the left and right sides better aligned. Method 2: The surface of the card board is arranged perpendicular to the extruded polystyrene board 2, which can make the extruded polystyrene boards 2 on the upper and lower sides better aligned.

[0045] A cavity is opened in the lower card board 6, and the upper card board 7 slides in the cavity opened in the lower card board 6. A guide groove 61 is opened on the inner side of the lower card board 6. A guide shaft 62 is connected to the bottom end of the upper card board 7, and the guide shaft 62 slides in the guide groove 61. The upper card board 7 can slide out of the lower card board 6 upwards.

[0046] The guide groove 61 includes a vertical guide groove and a horizontal guide groove, which are interconnected. One lower card board 6 corresponds to two upper card boards 7. When the two upper card boards 7 in the lower card board 6 slide into the horizontal guide groove along the vertical guide groove, the two upper card boards 7 move away from each other and fit against the inner surface of the card slot 5. At this time, the outer side surface of the upper card board 7 can be flush with the outer side surface of the lower card board 6, so as to better fit against the card slot 5, facilitating the connection work of adjacent low-energy composite insulation boards.

[0047] A number of limiting members 8 are arranged between the upper card boards 7. The limiting members 8 are provided with sliding grooves. The sliding grooves include an arc-shaped sliding groove 81 and a horizontal sliding groove 82 that are interconnected. The upper card board 7 is fixedly connected with a connecting plate 71. The connecting plate 71 is rotatably connected with a rotating shaft 72. The rotating shaft 72 is fixedly connected with a connecting rod 73. The connecting rod 73 is connected with a sliding shaft 74 that moves in the sliding groove.

[0048] In the initial state, the sliding shaft 74 slides in the arc-shaped chute 81. At this time, the upper surface of the uppermost limiting member 8 is higher than the upper surface of the upper clamping plate 7. When the two upper clamping plates 7 move away from each other, the sliding shaft 74 is driven by the connecting rod 73 to slide in the arc-shaped chute 81. When the sliding shaft 74 slides from the arc-shaped chute 81 into the horizontal chute 82, the sliding shaft 74 will continue to slide into the horizontal chute 82. Thus, after the upper clamping plate 7 moves away from each other, due to the limitation of the limiting member 8, since the sliding shaft 74 can only slide in the horizontal chute 82, the upper clamping plate 7 cannot move towards each other, realizing the automatic locking work after the movement of the upper clamping plate 7. At the same time, the upper surface of the uppermost limiting member 8 is flush with the upper surface of the upper clamping plate 7, better realizing the connection of the low-energy consumption composite insulation board.

[0049] When four composite insulation boards are combined to form a complete insulation wall, the following steps are included: S1: Align the two composite insulation boards located below to form a lower card slot, place the lower clamping plate 6 into the lower card slot, and then stack the remaining two composite insulation boards on the lower composite insulation board. At this time, the two composite insulation boards located above are aligned to form an upper card slot; S2: Attract the upper clamping plate 7 to move upward through a magnet. The upper clamping plate 7 slides upward in the cavity opened in the lower clamping plate 6, and the guide shaft 62 slides upward in the guide slot 61. When the upper clamping plate 7 slides out of the lower clamping plate 6 upward, at this time, the guide shaft 62 of the lower clamping plate 6 slides into the horizontal guide slot along the vertical guide slot; S3: As the guide shaft 62 slides in the vertical guide slot, the two upper clamping plates 7 move away from each other. At the same time, the upper clamping plate 7 drives the sliding shaft 74 to slide in the arc-shaped chute 81 through the connecting rod 73. When the sliding shaft 74 slides from the arc-shaped chute 81 into the horizontal chute 82, the sliding shaft 74 will continue to slide into the horizontal chute 82; S4: As the two upper clamping plates 7 continue to move away from each other, finally, the two upper clamping plates 7 are respectively attached to the inner surface of the upper card slot, and at the same time, the upper surface of the uppermost limiting member 8 is flush with the upper surface of the upper clamping plate 7, thereby realizing the connection work of the four composite insulation boards. At this time, the four composite insulation boards can be attached to the periphery of the template.
