Description

Technical Field

[0001] This invention relates to the field of integrated thermal insulation panels, and in particular to a steel wire mesh integrated thermal insulation panel structure and its construction method. Background Technology

[0002] Integrated thermal insulation panels are important materials in the fields of building energy conservation and structural protection, and are widely used in building exterior walls, roofs, and other parts. By combining the insulation layer with the structural layer, they achieve the dual functions of thermal insulation and wall support. Their core advantages lie in simplifying the construction process and improving building energy efficiency. They have become a key supporting material in green building and prefabricated building fields, and are widely used in residential, public buildings, and industrial facilities.

[0003] However, existing integrated thermal insulation panels suffer from several drawbacks in structural design and construction. These issues include reliance on adhesives or simple mechanical connections for panel splicing, leading to delamination and loosening due to external forces or temperature changes, resulting in insufficient overall integrity. Furthermore, the reinforcement structure often consists of unidirectional steel wire laying, lacking three-dimensional support and exhibiting limited shear and flexural strength, making it unsuitable for complex stress scenarios. The reliability of the fixing components to the panels is poor, leading to displacement during hoisting and installation, and the lack of targeted protective structures makes the panel edges susceptible to damage during transportation and reduces operational safety during construction. Therefore, a steel wire mesh integrated thermal insulation panel structure and its construction method are needed to address these problems. Summary of the Invention

A protective plate is provided at the left and right rear ends of the insulation board and the perlite board. The left and right protective plates are fixedly connected to the rear ends of the upper and lower connecting units. The connecting unit is used for the installation and disassembly of the protective plate, and also for connecting the insulation board and perlite board to the wall to form a support point. The protective plate is used for protection of the insulation board and perlite board during transportation and for anti-slip during installation.

[0005] Preferably, the front side of the insulation board is provided with a plurality of slots at equal intervals in the longitudinal direction, and the rear side of the perlite board is provided with a plurality of protrusions at equal intervals in the longitudinal direction, and the protrusions are engaged with the corresponding slots.

[0006] Preferably, each of the connecting units includes a plug, and the upper and lower parts of the plug are provided with a plurality of barbs at equal intervals. The front side of each plug is provided with a mounting plate, and the front side of each mounting plate is provided with a plurality of fixing bolts.

[0007] Preferably, a plurality of anti-slip blocks are evenly spaced on the rear side of the protective plate, and insertion holes are provided at both the upper and lower ends of the protective plate. The rear end of each plug is provided with a threaded head, and a locking nut is threaded to the outer side of each threaded head; The insertion holes provided on the upper and lower parts of the guard plate are all inserted into the rear end of the corresponding insertion bolts on the upper and lower parts.

[0008] A construction method for an integrated steel wire mesh insulation panel, applied to the aforementioned integrated steel wire mesh insulation panel structure, includes the following construction steps: S1. Cutting and pre-assembly: Cut the insulation board and perlite board according to the construction design dimensions, ensuring that the edges of both are flush, and simultaneously cut the groove on the front side of the insulation board and the protrusion on the back side of the perlite board to match the size of the groove and the protrusion. The insulation board and perlite board are assembled into a whole by using the slots and protrusions; on the inside of the assembled board, the installation holes for the diagonal reinforcing bars are reserved according to the design spacing, and the holes must correspond to the intersection of the subsequent horizontal and vertical reinforcing bars. S2.

Insert the inclined reinforcing bar obliquely into the reserved hole, ensuring that its front and rear ends extend to the intersection of the adjacent wire mesh frame. Bend the front and rear ends of the inclined reinforcing bar and tie and reinforce the intersection of the transverse and longitudinal wire reinforcing bars with stirrups. S3. Installation of connecting unit: Insert plugs into the mounting holes at the four corners of the insulation board and perlite board, so that the barbs on the outside of the plugs are fully extended and tightly abut against the inside of the mounting holes.

S4. Protective plate assembly: Align the insertion holes at the top and bottom of the protective plate with the rear ends of the insertion bolts of the upper and lower connecting units, insert the protective plate and make it fit tightly against the rear left and right ends of the insulation board and perlite board. Tighten the lock nut on the threaded head at the rear end of the plug until the protective plate is securely fixed. At this point, the anti-slip block of the protective plate faces outward, protecting the insulation board and perlite board from scratches during transportation, and providing an anti-slip gripping surface during installation. The insulation board, perlite board, horizontal steel wires, longitudinal steel wires, diagonal reinforcing bars, and protective board form a pre-assembled steel wire mesh integrated insulation board; S5. Hoisting and formwork installation: The pre-assembled steel wire mesh insulation integrated panel is slowly hoisted to the wall installation position by manual hoisting. It is temporarily fixed to the wall by the installation plate of the connecting unit and the pre-set connecting parts, and the verticality and horizontality of the panel are adjusted. Install templates on the outside of the board, leave a gap between the template and the board for concrete pouring, and seal the edges of the template with the protective board to prevent grout leakage during pouring; S6. Concrete pouring: Pour fine aggregate concrete into the gap between the formwork and the wall. During the pouring process, use a vibrator to gently vibrate to ensure that the concrete fills the gap and is tightly combined with the transverse steel wire, longitudinal steel wire and diagonal reinforcing bars. After pouring, curing should be carried out according to specifications. The formwork should be removed after the concrete strength reaches 70% of the design value.

[0009] Preferably, in step S1, the perpendicularity error of the cut edges of the insulation board and perlite board is ≤1mm, the fit gap between the slot and the protrusion is ≤0.8mm, the design spacing of the reserved oblique insertion rib holes is 250-300mm, and the diameter of the hole is 1-2mm larger than the diameter of the oblique insertion rib. In step S2, the spacing between the transverse and longitudinal steel wires is 200-250mm, the diameter of the steel wires is 4-6mm, and the intersections are tied with double strands of binding wire, with ≥3 rounds of binding. The inclination angle of the diagonal reinforcing bars is 45°, the bending length at the front and rear ends is 50-60mm, the bending angle is 120°, and the stirrups are made of galvanized iron wire with a diameter of 3mm.

[0010] Preferably, in step S3, the length of the plug is 100-150mm, the number of barbs is 4, the unfolding angle is 30°-45°, the diameter of the mounting plate is 50-60mm, the fixing bolt is of M6-M8 specification, and the depth of screwing into the perlite plate is ≥20mm. In step S4, the protective plate is made of galvanized steel plate with a thickness of 2-3mm, the anti-slip block is trapezoidal and the spacing is 80-100mm; the diameter of the insertion hole is 1mm larger than the diameter of the insertion bolt, the locking nut is M10 specification and the tightening torque is 25-30N・m.

[0011] Preferably, in step S5, the hoisting points are set at the mounting plates of the two upper connecting units, and a double-point balanced hoisting is adopted; the verticality deviation of the board is ≤3mm / m, and the horizontal deviation is ≤2mm / m; the template is a 15mm thick wooden template, and the gap between the template and the board is 50-80mm; the joint between the template and the protective plate is sealed with a sponge strip. In step S6, the strength grade of the fine aggregate concrete is ≥C30, and the maximum particle size of the aggregate is ≤15mm; a 30mm diameter micro vibrator is used, the vibration frequency is 50-60Hz, and the vibration time at each vibration point is 10-15s; curing is carried out by covering with geotextile and sprinkling water, with watering ≥3 times a day and curing days ≥7 days; when the formwork is removed, the compressive strength of the concrete cube is ≥70% of the design strength.

[0012] In summary, this invention provides a steel wire mesh integrated insulation panel structure and its construction method, which has the following beneficial effects: 1. By using the interlocking structure of the insulation board's slots and the perlite board's protrusions, combined with the orthogonal steel wire mesh formed by the outer horizontal and longitudinal steel wires and the three-dimensional connection of the inner diagonal reinforcing bars, the overall shear and flexural strength of the board is significantly improved, solving the problem of insufficient structural strength in traditional insulation boards. The outer horizontal and longitudinal steel wires are orthogonally arranged to form a rigid mesh, and the inner diagonal reinforcing bars obliquely penetrate the two boards and are tied at the intersection of the steel wire mesh, forming a composite structure of double-layer boards and a three-dimensional steel wire skeleton. This retains the insulation performance of the insulation board, and through the strength of the perlite board and the supporting effect of the horizontal, longitudinal, and diagonal reinforcing bars, the flexural strength of the integrated board is improved, solving the problem of insulation and load-bearing capacity in traditional insulation boards.

[0013] 2. By inserting diagonal reinforcing bars at a 45° angle into the inner side of the insulation board and perlite board, and then bending them at the front and rear ends, they are tightly bound to the intersections of the horizontal and vertical steel wires. This transforms the planar stress of the boards into a three-dimensional, distributed stress. When the boards are subjected to external impact, the diagonal reinforcing bars can transfer the force to the wire mesh, preventing localized stress concentration that could lead to cracking of the insulation board or damage to the perlite board, thus significantly improving the overall shear resistance. The double fixing structure of the connecting unit's plug-in barbs and fixing bolts, combined with the symmetrical distribution design at the four corners, achieves a stable connection between the insulation board, perlite board, and the wall, while providing a reliable installation foundation for the protective board, ensuring uniform stress during hoisting and use.

[0014] 3. Through the coordinated operation of steps S1, S2, and S3, modular pre-assembly of insulation boards and perlite boards is achieved, reducing on-site construction steps and improving installation efficiency. Specifically, the slot-protrusion engagement in S1 ensures tight splicing of the boards, the three-dimensional steel wire structure in S2 enhances the overall strength, and the double-fixed connection unit in S3 provides reliable support for hoisting and wall fixing. The combination of these three features significantly shortens the construction cycle. Through the process design of steps S4, S5, and S6, the entire process from transportation protection to structural forming is guaranteed. The protective board in S4 ensures safe transportation and convenient installation through anti-slip blocks and locking nuts, the double-lifting point hoisting and formwork sealing in S5 ensures installation accuracy and pouring quality, and the fine stone concrete wrapped with steel wire and diagonal reinforcing bars in S6 forms an integrated load-bearing structure, ultimately achieving dual optimization of thermal insulation performance and structural stability.

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.

[0018] Example: Please see Figures 1-8 As shown, the present invention provides a technical solution: a steel wire mesh frame insulation integrated panel structure, including an insulation board 1 and a perlite board 2, wherein a plurality of transverse steel wires 3 are arranged at equal intervals on the outer side of the insulation board 1 and the perlite board 2, and a plurality of longitudinal steel wires 4 are arranged at equal intervals on the outer side of the insulation board 1 and the perlite board 2, wherein the plurality of equally spaced transverse steel wires 3 and longitudinal steel wires 4 form a steel wire mesh frame structure; The inner sides of the insulation board 1 and the perlite board 2 are equidistantly inserted into several oblique reinforcing bars 5. The front and rear ends of the oblique reinforcing bars 5 are located at the intersection of the transverse steel wire 3 and the longitudinal steel wire 4. The front and rear ends of the oblique reinforcing bars 5 are bent. A connecting unit 6 is provided at each of the four corners of the insulation board 1 and the perlite board 2. A protective plate 7 is provided at the left and right ends of the rear part of the insulation board 1 and the perlite board 2. The left and right protective plates 7 are fixedly connected to the rear end of the upper and lower connecting units 6. The connecting unit 6 is used for the installation and disassembly of the protective plate 7, and also for connecting the insulation board 1 and the perlite board 2 to the wall to form a support point. The protective plate 7 is used for the protection of the insulation board 1 and the perlite board 2 during transportation and for anti-slip during the installation process.

[0019] The front side of the insulation board 1 has several slots 101 arranged longitudinally at equal intervals, and the rear side of the perlite board 2 has several protrusions 201 arranged longitudinally at equal intervals. The protrusions 201 are engaged with the corresponding slots 101. Through the precise engagement of the slots 101 and the protrusions 201, the insulation board 1 and the perlite board 2 are tightly connected, enhancing the integrity of the composite board.

[0020] Each connecting unit 6 includes a plug 601. Several barbs 602 are equidistantly arranged on the upper and lower outer sides of the plug 601. A mounting plate 603 is provided on the front side of each plug 601. Several fixing bolts 604 are provided on the front side of each mounting plate 603. The barbs 602, the mounting plate 603, and the fixing bolts 604 form a double fixing structure. The barbs 602 enable quick locking after insertion, and the fixing bolts 604 enhance the connection strength, ensuring that the connecting unit 6 has sufficient load-bearing capacity. Mounting holes 8 are provided at the four corners of the insulation board 1 and the perlite board 2. The plugs 601 are inserted into the inner side of the corresponding mounting holes 8, and the barbs 602 abut against the inner side of the corresponding mounting holes 8. The cooperation between the mounting holes 8 and the plugs 601 ensures that the connecting unit 6 is accurately positioned. The tight abutment between the barbs 602 and the inner wall of the mounting hole 8 can effectively prevent the plugs from loosening or falling off.

[0021] The protective plate 7 has several anti-slip blocks 701 evenly spaced on its rear side. The upper and lower ends of the protective plate 7 are provided with insertion holes 702. The anti-slip blocks 701 can increase the friction and prevent the plates from slipping during transportation. They also provide a stable gripping point during installation. The insertion holes 702 make the assembly of the protective plate 7 and the connecting unit 6 more convenient and facilitate quick loading and unloading. The rear end of each plug 601 is provided with a threaded head 605, and the outer side of each threaded head 606 is threaded with a locking nut 606. The cooperation between the threaded head and the locking nut 606 can realize the detachable fixing of the protective plate 7, which is convenient for flexible installation or removal of the protective plate 7 according to the construction stage, while ensuring the reliability of the fixing of the protective plate 7 during transportation and installation. The insertion holes 702 provided on the upper and lower parts of the protective plate 7 are all inserted into the rear end of the corresponding insertion bolts 601 on the upper and lower parts. Through the precise cooperation between the insertion holes 702 and the insertion bolts 601, the protective plate 7 is tightly attached to the rear end of the board, which can effectively protect the edges of the insulation board 1 and the perlite board 2 from collision damage during transportation.

[0022] A construction method for an integrated steel wire mesh insulation panel, applied to the aforementioned integrated steel wire mesh insulation panel structure, includes the following construction steps: S1. Cutting and pre-assembly: According to the construction design dimensions, the insulation board 1 and perlite board 2 are cut to ensure that the edges of both are flush. At the same time, the groove 101 on the front side of the insulation board and the protrusion 201 on the back side of the perlite board are cut to match the size of the groove and the protrusion. Precise cutting ensures the consistency of the size of the insulation board 1 and the perlite board 2. The matching design of the groove 101 and the protrusion 201 provides a good foundation for subsequent splicing and reduces on-site adjustment time. Insulation board 1 and perlite board 2 are assembled into a whole by engaging the slot 101 and the protrusion 201. On the inner side of the assembled board, the installation holes for the diagonal reinforcing bars 5 are reserved according to the design spacing. The holes must correspond to the intersection of the subsequent horizontal steel wire reinforcing bars 3 and the vertical steel wire reinforcing bars 4. The engaging assembly enhances the integrity of insulation board 1 and perlite board 2. The holes correspond to the intersection of the horizontal steel wire reinforcing bars 3 and the vertical steel wire reinforcing bars 4 to ensure that the diagonal reinforcing bars 5 can be accurately connected to the steel wire mesh frame, laying the foundation for the three-dimensional reinforced structure. S2. Installation of wire mesh frame and diagonal reinforcing bars: On the outside of the assembled insulation board 1 and perlite board 2, lay transverse wire reinforcing bars 3 at equal intervals and longitudinal wire reinforcing bars 4 to form an orthogonal wire mesh frame structure. The orthogonal wire mesh frame forms a rigid support on the outside of the insulation board 1 and perlite board 2, evenly dispersing external forces and improving the deformation resistance of the boards. The oblique insert 5 is inserted obliquely into the reserved hole, ensuring that its front and rear ends extend to the intersection of the adjacent wire mesh frame. The front and rear ends of the oblique insert 5 are bent and the intersection of the transverse wire 3 and the longitudinal wire 4 is reinforced with stirrups. The three-dimensional connection formed by the oblique insert 5, the transverse wire 3, and the longitudinal wire 4 constitutes the outer frame and the inner oblique bracing structure, which significantly improves the overall shear and bending resistance of the insulation board 1 and the perlite board 2. The stirrup binding ensures that the connection node is firm. S3. Installation of connecting unit: Insert the plug 601 into the mounting holes 8 at the four corners of the insulation board 1 and the perlite board 2, so that the barbs 602 on the outside of the plug are fully extended and tightly abut against the inside of the mounting hole 8. At the same time, attach the mounting plate 603 to the front side of the perlite board, and fix the connecting unit 6 by passing the mounting plate 603 through the fixing bolt 604 and screwing it into the preset screw hole of the perlite board 2. The double fixation of the barbs 602 and the fixing bolt 604 ensures that the connecting unit 6 forms a rigid connection with the insulation board 1 and the perlite board 2. The connecting units 6, which are symmetrically distributed at the four corners, can evenly distribute the force during hoisting and use. S4. Protective plate assembly: Align the insertion holes 702 at the upper and lower ends of the protective plate 7 with the rear end of the insertion bolts 601 of the upper and lower connecting unit 6, insert it, and make the protective plate 7 fit tightly against the rear left and right ends of the insulation board and perlite board. The protective plate 7 fitting tightly against the board can effectively buffer the impact force during transportation and prevent the edges of the insulation board 1 and perlite board 2 from being damaged. Tighten the locking nut 606 on the threaded head 605 at the rear end of the plug 601 until the protective plate 7 is firmly fixed. At this time, the anti-slip block 701 of the protective plate faces outward, protecting the insulation board 1 and perlite board 2 from scratches during transportation, and providing an anti-slip gripping surface during installation. The locking nut 606 ensures that the protective plate 7 does not loosen during transportation. The anti-slip block 701 is designed to take into account both anti-slip during transportation and safety during installation. Pre-assembly reduces on-site operation steps. Insulation board 1, perlite board 2, transverse steel wire reinforcement 3, longitudinal steel wire reinforcement 4, diagonal reinforcement 5, connecting unit 6, and protective board 7 form a pre-assembled steel wire mesh frame integrated insulation board; S5. Hoisting and Formwork Installation: The pre-assembled steel wire mesh insulation integrated panel is slowly hoisted to the wall installation position by manual hoisting. It is temporarily fixed to the wall by the installation plate 603 of the connecting unit 6 and the pre-set connector. The verticality and horizontality of the panel are adjusted. Manual hoisting is suitable for operation in narrow spaces. The temporary fixing of the installation plate 603 to the wall facilitates the precise adjustment of the position of the insulation board 1 and the perlite board 2, ensuring installation accuracy. A template is installed on the outside of the board, with a gap reserved between the template and the board for concrete pouring. The edge of the template is sealed to the protective plate 7 to prevent grout leakage during pouring. The reserved gap ensures that the concrete can fully wrap the transverse steel wire 3, longitudinal steel wire 4 and diagonal reinforcing bars 5 to form an integral load-bearing structure. The sealing treatment avoids concrete waste and structural defects caused by grout leakage. S6. Concrete pouring: Pour fine aggregate concrete into the gap between the formwork and the wall. During the pouring process, use a vibrator to gently vibrate to ensure that the concrete fills the gap and is tightly bonded to the transverse steel wire 3, longitudinal steel wire 4 and diagonal reinforcing bars 5. Fine aggregate concrete has good fluidity and can fill the fine gaps. Vibration makes the concrete fully bonded to the transverse steel wire 3, longitudinal steel wire 4 and diagonal reinforcing bars 5, improving the overall structure. After pouring, curing should be carried out according to specifications. The formwork should be removed after the concrete strength reaches 70% of the design value. Standard curing ensures that the concrete strength increases steadily. The formwork should be removed after the strength requirement is met to avoid deformation of the insulation board 1, perlite board 2 and wire mesh frame due to premature stress.

[0023] In step S1, the perpendicularity error of the cut edges of insulation board 1 and perlite board 2 is ≤1mm, the fit gap between the slot 101 and the protrusion 201 is ≤0.8mm, the design spacing of the reserved oblique insertion rib 5 holes is 250-300mm, and the hole diameter is 1-2mm larger than the diameter of the oblique insertion rib 5. High-precision cutting and fit gap control ensure that insulation board 1 and perlite board 2 are spliced ​​flat. The hole parameter design facilitates the installation of oblique insertion rib 5 and avoids shaking caused by excessive gap. In step S2, the spacing between the transverse steel wire reinforcing bars 3 and the longitudinal steel wire reinforcing bars 4 is 200-250mm, the diameter of the steel wire reinforcing bars is 4-6mm, and the intersections are tied with double strands of binding wire, with ≥3 rounds of binding. The inclination angle of the diagonal reinforcing bars 5 is 45°, the bending length at the front and rear ends is 50-60mm, and the bending angle is 120°. The stirrups are made of galvanized iron wire with a diameter of 3mm. The parameters of the transverse steel wire reinforcing bars 3 and the longitudinal steel wire reinforcing bars 4 take into account both strength and economy. Double-strand binding ensures that the nodes are firm. The 45° diagonal reinforcing bars 5 and the 120° bending design optimize the force transmission path. The galvanized iron wire stirrups are rust-proof and tightly bound.

[0024] In step S3, the length of the plug 601 is 100-150mm, the number of barbs 602 is 4, the unfolding angle is 30°-45°, the diameter of the mounting plate 603 is 50-60mm, the fixing bolt 604 adopts the M6-M8 specification, the depth of screwing into the perlite board 2 is ≥20mm, the length of the plug 601 is adapted to the thickness of the insulation board 1 and the perlite board 2, and the design of the 4 barbs 602 and their angles ensures uniform biting force; the diameter of the mounting plate 603 matches the specification of the fixing bolt 604 to ensure that the connection strength meets the requirements of hoisting and fixing. In step S4, the protective plate 7 is made of galvanized steel plate with a thickness of 2-3mm. The anti-slip block 701 is trapezoidal and the spacing between them is 80-100mm. The diameter of the insertion hole 702 is 1mm larger than the diameter of the insertion bolt 601. The locking nut 606 is of M10 specification and the tightening torque is 25-30N・m. The protective plate 7 made of galvanized steel plate has both strength and corrosion resistance. The anti-slip effect of the trapezoidal anti-slip block 701 is better than that of the flat design. The gap of the insertion hole 702 and the tightening torque of the locking nut 606 are controlled to ensure that the protective plate 7 is easy to install and securely fixed.

[0025] In step S5, the hoisting points are set at the installation plates 603 of the two upper connecting units 6, and a double-point balanced hoisting method is used; the verticality deviation of the board is ≤3mm / m, and the horizontal deviation is ≤2mm / m; 15mm thick wooden formwork is used, with a 50-80mm gap between the formwork and the board during pouring; the joint between the formwork and the protective board 7 is sealed with sponge strips; the double-point hoisting method avoids tilting and deformation of the insulation board 1, perlite board 2, and wire mesh frame, and the precision control meets the specifications; the wooden formwork and sponge strip sealing method is low-cost and has a good sealing effect, and the pouring gap ensures the thickness of the concrete protective layer; In step S6, the strength grade of fine aggregate concrete is ≥C30, and the maximum particle size of the aggregate is ≤15mm; a 30mm diameter micro vibrator is used, with a vibration frequency of 50-60Hz and a vibration time of 10-15s at each vibration point; curing is carried out by covering with geotextile and watering, with watering ≥3 times a day and a curing period of ≥7 days; when removing the formwork, the compressive strength of the concrete cube is ≥70% of the design strength, and C30 concrete and small-diameter aggregate ensure structural strength and fluidity, while the micro vibrator is suitable for narrow gaps; standardized curing and formwork removal strength control ensure that the concrete strength meets the standards and avoid early damage to the insulation board 1, perlite board 2, and the overall structure.

Cutting and pre-assembly: According to the construction design dimensions, cut the insulation board (1) and perlite board (2) to ensure that the edges of the two are flush, and simultaneously cut the groove (101) on the front side of the insulation board and the protrusion (201) on the back side of the perlite board so that the groove and the protrusion match in size. The insulation board (1) and perlite board (2) are assembled into a whole by engaging the slot (101) and the protrusion (201); on the inner side of the assembled board, the installation holes of the inclined reinforcing bars (5) are reserved according to the design spacing, and the holes must correspond to the intersection of the subsequent transverse steel wire reinforcing bars (3) and longitudinal steel wire reinforcing bars (4). S2. Installation of wire mesh frame and diagonal reinforcing bars: On the outside of the assembled insulation board (1) and perlite board (2), lay transverse wire reinforcing bars (3) at equal intervals and longitudinal wire reinforcing bars (4) to form an orthogonal wire mesh frame structure. Insert the oblique reinforcing bar (5) obliquely into the reserved hole, ensuring that its front and rear ends extend to the junction of the adjacent wire mesh frame. Bend the front and rear ends of the oblique reinforcing bar (5) and reinforce the junction of the transverse wire reinforcing bar (3) and the longitudinal wire reinforcing bar (4) with stirrups. S3. Installation of connecting unit: Insert plugs (601) into the mounting holes (8) at the four corners of the insulation board (1) and the perlite board (2), so that the barbs (602) on the outside of the plugs are fully unfolded and tightly abut against the inside of the mounting holes (8). At the same time, attach the mounting plate (603) to the front side of the perlite board, and use fixing bolts (604) to pass through the mounting plate (603) and screw into the pre-set screw holes of the perlite board (2) to fix the connecting unit (6). S4.
