Through the cooperation of the edge frame, trapezoidal strip, first wedge strip, and second wedge strip, as well as the matching of the longitudinal stabilizing groove and the longitudinal stabilizing block, precise positioning between the insulation layer and the structural layer is achieved, restricting the longitudinal and lateral displacement of the structures of each layer without the need for repeated manual calibration; through the cooperation of components such as the clamping block, abutting spring, retaining seat, abutting block, torsion spring, pull rod, insertion block, and compensation spring, automatic locking between the structures of each layer is achieved, with simple operation and low requirements for workers' skills; the serrated groove of the second structural layer meshes with the serrated block at the top of the edge frame of the first structural layer, generating an axial deviation correction force, which is beneficial to improving the splicing accuracy. The design of these mechanisms makes the installation process simple and fast, without the need to use bolts or slide rails, greatly shortening the installation time, reducing the installation difficulty, and also greatly reducing the requirements for workers' skills.

[0022] 2. The present invention adopts a heat bridge blocking structure that combines mechanical biting and an elastic buffer layer to replace the traditional adhesive connection method. The serrated ribs, reinforcing ribs, and elastic buffer layer together constitute multiple thermal resistance paths. Through mechanical biting and the filling of the elastic buffer layer, a firm connection between the insulation layer and the structural layer is achieved. This connection method is not affected by temperature and humidity, avoiding the problem of adhesive aging, and significantly improving the long-term reliability and durability of the insulation layer.

[0023] 3. The present invention forms multiple thermal resistance paths through the serrated ribs, reinforcing ribs, and elastic buffer layer in the heat bridge blocking structure. The staggered biting extends the heat transfer path, the serrated structure increases the contact thermal resistance, and the compression deformation fills the biting gap, blocking the convective heat conduction of air. At the same time, it absorbs the structural deformation stress. Compared with traditional adhesives, this structure can more effectively prevent the transfer of heat and improve the insulation performance. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figure 1 This is a schematic structural diagram of the prefabricated building insulation board component of the present invention. The present invention provides a technical solution: a prefabricated building insulation board component, including a first structural layer 1, a thermal insulation layer 2 and a second structural layer 3. A positioning and splicing mechanism is provided between the first structural layer 1 and the thermal insulation layer 2, and between the thermal insulation layer 2 and the second structural layer 3. The first structural layer 1 and the second structural layer 3 provide the main support of the component, which is usually made of steel and has sufficient strength and stiffness. The thermal insulation layer 2 adopts an extruded polystyrene composite board structure. The first structural layer 1 and the second structural layer 3 provide load-bearing and support, and the thermal insulation layer 2 provides heat insulation and heat preservation functions.

Figure 4 This is a schematic structural diagram of the thermal insulation layer of the present invention. Figure 5Schematic diagram of the first structural layer of the present invention. The positioning and splicing mechanism includes an edge frame 11, a trapezoidal strip 21, and a second wedge strip 31. The edge frame 11 and the first structural layer 1 are of an integrally formed structure. Longitudinal stabilizing grooves 12 are provided on both sides of the edge frame 11. Serrated blocks 13 are fixedly connected to both sides of the top of the edge frame 11. Through grooves 15 are provided at both ends of the edge frame 11. First wedge strips 14 are fixedly connected to both sides of the first structural layer 1. Grooves 4 are provided at both ends of the edge frame 11.

[0038] Two trapezoidal strips 21 and the insulation layer 2 are of an integrally formed structure respectively. Longitudinal stabilizing blocks 22 are fixedly connected to both sides of the insulation layer 2. The longitudinal stabilizing blocks 22 are in a "C" shape and are mutually matched with the longitudinal stabilizing grooves 12 to limit the longitudinal displacement between the insulation layer 2 and the first structural layer 1, replacing the traditional bolt positioning. Limiting grooves 23 are provided on both sides of the longitudinal stabilizing blocks 22.

[0039] The edge frame 11 serves as the edge support and connection component of the first structural layer 1. The matching of the longitudinal stabilizing grooves 12 and the longitudinal stabilizing blocks 22 limits the longitudinal displacement between the insulation layer 2 and the first structural layer 1, replacing the traditional bolt positioning to achieve precise positioning and stable connection. The grooves 4 are used to install the interlocking mechanism. The trapezoidal strips 21 and the insulation layer 2 are integrally formed. The first wedge strips 14 and the second wedge strips 31 are integrally formed with the first structural layer 1 and the second structural layer 3 respectively. The three cooperate and are clamped in the clamping grooves formed by the trapezoidal strips 21 to limit the lateral displacement between the insulation layer 2 and the structural layer and ensure the firmness of the connection.

[0040] Two second wedge strips 31 and the second structural layer 3 are of an integrally formed structure respectively. Both the second wedge strips 31 and the first wedge strips 14 are clamped in the clamping grooves formed by the trapezoidal strips 21 to limit the lateral displacement between the insulation layer 2 and the structural layer. Serrated grooves 32 are provided on both sides of the second structural layer 3. A plurality of serrated grooves 32 are mutually matched with the serrated blocks 13. The meshing between the serrated grooves 32 and the serrated blocks 13 generates an axial deviation correction force, which is beneficial to the splicing accuracy. Block seats 5 are fixedly connected to the bottom of both ends of the second structural layer 3.

[0041] The longitudinal stabilizing blocks 22 on both sides of the insulation layer 2 are mutually matched with the longitudinal stabilizing grooves 12 on both sides of the edge frame 11 of the first structural layer 1 to limit the longitudinal displacement of the insulation layer 2. The first wedge strips 14 on both sides of the first structural layer 1 and the second wedge strips 31 on both sides of the second structural layer 3 are respectively clamped in the clamping grooves formed by the trapezoidal strips 21 to limit the lateral displacement between the insulation layer 2 and the structural layer.

[0042] Figure 6 Schematic diagram of the structure at the groove of the present invention. Figure 7This is a schematic structural diagram of the interlocking mechanism of the present invention. The first structural layer 1 and the thermal insulation layer 2 are connected through the interlocking mechanism. The interlocking mechanism includes a trapezoidal strip 21 and a clamping block 43. An installation plate 41 is arranged at the opening of the groove 4. The installation plate 41 is fixed on the edge frame 11 by a predetermined screw. A guide rod 42 is slidably inserted into the installation plate 41. A clamping block 43 is arranged at the end of the guide rod 42. The end of the clamping block 43 is of an inclined surface structure and is correspondingly arranged with the limiting groove 23.

[0043] A contact spring 44 is sleeved on the guide rod 42. The model of the contact spring 44 can be selected according to the actual working conditions. Under the push of the contact spring 44, the guide rod 42 makes the inclined surface of the clamping block slide into the limiting groove 23 to achieve automatic locking. The contact spring 44 provides the elastic force of the clamping block 43 to ensure that the clamping block 43 closely adheres to the limiting groove 23.

[0044] Figure 3 This is a schematic structural diagram of the retaining seat of the present invention. The end of the retaining seat 5 penetrates through the through groove 15 and extends into the groove 4. The retaining seat 5 is located between the installation plate 41 and the clamping block 43. A receiving groove 51 is opened on one side of the retaining seat 5. A pin shaft 52 is fixedly connected in the receiving groove 51 of the retaining seat 5. An abutting block 54 is rotatably sleeved on the pin shaft 52. A torsion spring 53 is sleeved on the pin shaft 52. One end of the torsion spring 53 is fixed on the pin shaft 52 and the other end is fixed on the abutting block 54.

[0045] The end of the abutting block 54 is of a rubber layer structure and abuts on one side of the clamping block 43. After the retaining seat is inserted into the through groove 15, the abutting block 54 presses the clamping block 43 under the action of the torsion spring 53 to enhance the locking force. A slot 55 is opened on one side of the retaining seat 5.

[0046] The retaining seat 5 passes through the through groove 15 and extends into the groove 4, playing a role of connection and locking. The abutting block 54 is connected to the retaining seat 5 through the pin shaft 52 and presses the clamping block 43 under the action of the torsion spring 53 to enhance the locking force and prevent accidental unlocking. The rubber layer structure of the rubber layer of the abutting block 54 increases the friction force and further improves the locking effect.

[0047] Figure 8 This is a schematic structural diagram of the blocking structure of the present invention. Figure 9 This is a cross-sectional view of the cavity seat of the present invention. A cavity seat 6 is fixedly connected in the groove 4 on the edge frame 11. A pull rod 61 is slidably inserted into the installation plate 41. An insertion block 62 is arranged at the end of the pull rod 61. The end of the insertion block 62 is of an inclined surface structure and is correspondingly arranged with the slot 55. A compensation spring 63 is sleeved on the pull rod 61. The pull rod 61 drives the insertion block 62 to insert into the slot 55 to form the fixation of the retaining seat 5, that is, the locking between the second structural layer 3 and the first structural layer 1.

[0048] An extension block 45 is fixedly connected to one side of the end of the guide rod 42. A receiving groove is provided on the extension block 45. A positioning block 46 is provided at the opening of the receiving groove. The positioning block 46 is fixed to the extension block 45 by a predetermined screw. A stopper 47 is slidably inserted into the positioning block 46. The end of the stopper 47 forms a block against the pulling rod 61 to prevent accidental movement of the pulling rod 61. A support spring 48 is fixedly connected between the stopper 47 and the receiving groove. The model of the support spring 48 can be selected according to actual working conditions.

[0049] The cavity seat 6 is fixed in the groove 4 of the edge frame 11, providing sliding space for the pulling rod 61. The pulling rod 61 drives the insert block 62 to be inserted into the slot 55 of the block seat 5. Under the action of the compensation spring 63, the block seat 5 is fixed in the through groove 15 to achieve locking between the second structural layer 3 and the first structural layer 1. Under the action of the support spring 48, the block 47 presses against the pulling rod 61 to prevent it from accidentally moving, thereby ensuring the stability of the connection.

[0050] Figure 10 This is a structural schematic diagram of the thermal bridge blocking structure of the present invention. Thermal bridge blocking structures are provided between the first structural layer 1 and the thermal insulation layer 2, and between the thermal insulation layer 2 and the second structural layer 3. The thermal bridge blocking structure includes serrated ribs 7 and reinforcing ribs 8. Multiple serrated ribs 7 are distributed on one side of the structural layer, and multiple reinforcing ribs 8 are distributed on one side of the thermal insulation layer 2. The serrated ribs 7 and the reinforcing ribs 8 are staggered to form a mechanical bite.

[0051] An elastic buffer layer 9 is bonded between the serrated ribs 7 and the reinforcing ribs 8. The elastic buffer layer 9 is a closed-cell foamed aluminum composite material. The serrated ribs 7, the reinforcing ribs 8 and the elastic buffer layer 9 together constitute multiple thermal resistance paths. The staggered bite extends the heat transfer path. The serrated structure increases the contact thermal resistance. The compression deformation fills the bite gap, blocks the air convection heat conduction, and absorbs the structural deformation stress at the same time.

[0052] The elastic buffer layer 9 is a closed-cell foamed aluminum composite material with good thermal insulation performance. It fills the gap between the serrated ribs 7 and the reinforcing ribs 8, blocks air convection, and further improves the thermal insulation effect. At the same time, the elastic buffer layer 9 can absorb structural deformation stress and improve the durability of the component.

[0053] During actual installation, the insulation layer 2 is preliminarily positioned with the first structural layer 1 through two integrally formed trapezoidal bars 21. The longitudinal stabilizing blocks 22 on both sides of the insulation layer 2 match the longitudinal stabilizing grooves 12 on both sides of the edge frame 11 of the first structural layer 1 to limit the longitudinal displacement of the insulation layer 2. The first wedge bars 14 on both sides of the first structural layer 1 and the second wedge bars 31 on both sides of the second structural layer 3 are respectively engaged in the engaging grooves formed by the trapezoidal bars 21 to limit the lateral displacement between the insulation layer 2 and the structural layer.

[0054] Engage the serrated grooves 32 of the second structural layer 3 with the serrated blocks 13 at the top of the edge frame 11 of the first structural layer 1 to generate an axial deviation correction force, which is beneficial to the splicing accuracy. Insert the retaining seats 5 of the second structural layer 3 into the through grooves 15 at both ends of the edge frame 11 of the first structural layer 1 and extend them into the grooves 4;

[0055] The inclined surface of the clamping block 43 at the end of the guide rod 42 slides into the limiting groove 23 of the longitudinal stabilizing block 22 of the thermal insulation layer 2. The abutting spring 44 pushes the guide rod 42 to make the clamping block 43 closely adhere to the limiting groove 23 to achieve automatic locking. The abutting block 54 of the retaining seat 5 presses the clamping block 43 under the action of the torsion spring 53 to enhance the locking force and lock the first structural layer 1 and the thermal insulation layer 2;

[0056] Fix the cavity seat 6 in the groove 4 of the edge frame 11. Slide and insert the tension rod 61 onto the mounting plate 41. The inclined surface of the insertion block 62 at the end of the tension rod 61 inserts into the slot 55 of the retaining seat 5. The compensating spring 63 pushes the tension rod 61 to drive the insertion block 62 to insert into the slot 55 to form the fixation of the retaining seat 5, that is, to achieve the locking between the second structural layer 3 and the first structural layer 1. The blocking block 47 on the extension block 45 abuts against the tension rod 61 under the action of the supporting spring 48 to prevent its accidental movement.

[0057] The present invention designs a delicate positioning and splicing mechanism and an interlocking mechanism to achieve precise positioning and firm connection between various structural layers. Through the cooperation of the edge frame 11, the trapezoidal strip 21, the first wedge strip 14 and the second wedge strip 31, as well as the matching of the longitudinal stabilizing groove 12 and the longitudinal stabilizing block 22, precise positioning between the thermal insulation layer and the structural layer is achieved, restricting the longitudinal and lateral displacements of each structural layer without manual repeated calibration; through the cooperation of components such as the clamping block 43, the abutting spring 44, the retaining seat 5, the abutting block 54, the torsion spring 53, the tension rod 61, the insertion block 62 and the compensating spring 63, automatic locking between various structural layers is achieved, with simple operation and low requirements for workers' skills; the serrated grooves 32 of the second structural layer 3 engage with the serrated blocks 13 at the top of the edge frame 11 of the first structural layer 1 to generate an axial deviation correction force, which is beneficial to improving the splicing accuracy; the design of these mechanisms makes the installation process simple and fast, without the use of bolts or sliding rails, greatly shortening the installation time, reducing the installation difficulty, and also greatly reducing the requirements for workers' skills.
