After the foam blocks are produced by manufacturer A, they are transported to manufacturer B for concrete pouring and molding. If the connecting nails are first installed in the foam blocks at manufacturer A, it will affect the transportation of the foam blocks and bring inconvenience to transportation.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] For reference Figure 1-5 The utility model is described as follows:

[0024] Embodiment 1: A lightweight thermal insulation concrete block comprises a thermal insulation block 1, wherein the thermal insulation block 1 is a foam block, and concrete blocks 2 are respectively arranged on the left and right sides of the thermal insulation block 1, and connecting nails are arranged between the thermal insulation block 1 and the concrete block 2 to connect the two. Foam blocks have the following significant advantages as thermal insulation materials: Excellent thermal insulation performance: The interior thereof is full of tiny closed pores, which effectively prevent the transfer of heat. Lightweight: The overall weight of the blocks is greatly reduced, which is convenient for construction and transportation. Concrete blocks provide the following important functions: Structural strength: Provide the blocks with sufficient compressive and tensile strength to ensure the stability and safety of the wall. Fireproof performance: Compared with foam blocks, concrete has better fireproof performance, which increases the fireproof ability of the wall. The connecting nails play a key connecting role in it: Stable combination: Ensure that the thermal insulation block 1 and the concrete block 2 are tightly connected without separation or dislocation.

[0025] The connecting nails include a fixed nail 3 and a movable nail 4. The fixed nail 3 is inserted into the interior of the insulation block 1, and the movable nail 4 is movably inserted into the fixed nail 3. The fixed nail 3 is a columnar structure (columnar structure: provides a stable insertion foundation, which is convenient for inserting into the insulation block 1), and the movable nail 4 is a tubular structure. A plug-in hole 5 is formed in the movable nail 4, and the plug-in hole 5 is arranged along the axial direction of the movable nail 4. The fixed nail 3 is movably inserted into the plug-in hole 5 (the tubular structure and the plug-in hole 5: provide space for cooperation with the fixed nail 3 to realize the function of movable insertion). The rear end of the movable nail 4 is connected to a fixed disk 8, and the diameter of the fixed disk 8 is larger than the diameter of the movable nail 4 (the fixed disk 8 at the rear end: the diameter is larger than the movable nail 4, which can prevent the movable nail 4 from being excessively inserted into the insulation block 1, and plays a role in limiting the position). The front end of the fixed nail 3 is connected with a drill bit 9, which is a tapered structure with a small front and a large back. The diameter of the rear end of the drill bit 9 is equal to the diameter of the movable nail 4 (the front end of the drill bit 9: the tapered structure is conducive to reducing the resistance during insertion, so that the fixed nail 3 can be drilled into the insulation block 1 more easily), and the side wall of the drill bit 9 is provided with an anti-slip barb 10. The fixed nail 3 is inserted into the insulation block 1 with the help of the drill bit 9 at its front end, and the movable nail 4 is inserted into the insulation block 1 together with the fixed nail 3. A pre-tightening force will be formed between the movable nail 4 and the insulation block 1 to prevent the movable nail 4 from moving at will. The movable nail 4 can only move when the movable nail 4 is pulled. Overall function and advantages: Stable connection: After the fixed nail 3 is inserted into the insulation block 1, the movable nail 4 is inserted accordingly. The cooperation between the two and the pre-tightening force generated between the movable nail 4 and the insulation block 1 ensure the stability of the connection, so that the insulation block 1 and the concrete block 2 can be tightly combined. Flexibility: The movable nail 4 can only move when a pulling force is applied. This design has a certain flexibility in construction, and the position or state of the movable nail 4 can be adjusted as needed. Enhanced connection effect: Through the synergistic effect of the fixed nail 3 and the movable nail 4, the reliability and durability of the connection between the insulation block 1 and the concrete block 2 are improved.

[0026] The fixing nail 3 is provided with a limiting slide groove 6 penetrating through both radial sides thereof, and the limiting slide groove 6 is extended along the axial direction of the fixing nail 3. A limiting strip 7 is provided on the inner side of the movable nail 4, and both ends of the limiting strip 7 are respectively fixedly connected to the side walls of the plug hole 5. The limiting strip 7 passes through the limiting slide groove 6 and is slidably connected to the limiting slide groove 6. In this way, the limiting strip 7 can only move along the axial direction of the fixing nail 3 within the range limited by the limiting slide groove 6.

[0027] Its main functions are as follows:

[0028] Guiding function: ensuring that the movable nail 4 remains stable when moving axially along the fixed nail 3, and does not rotate or deviate from the axis.

[0029] Limiting the moving range: By limiting the length of the slide groove 6, the maximum moving distance of the movable pin 4 relative to the fixed pin 3 is limited, preventing the movable pin 4 from moving excessively.

[0030] Collaborative work: The fixed nail 3 and the movable nail 4 can work better together. When the fixed nail 3 is inserted into the insulation block 1, the movable nail 4 can smoothly move along the axial direction within a certain range. At the same time, due to the cooperation between the limiting strip 7 and the limiting slide groove 6, the movable nail 4 will not shake or fall off at will.

[0031] In the actual installation process, after the drill bit 9 of the fixed nail 3 is drilled into the insulation block 1, the movable nail 4 can move within a certain stroke to adapt to different installation requirements or adjust the preload force. The structure of the limiting slide 6 and the limiting bar 7 can ensure that the movement of the movable nail 4 is orderly and stable, and there will be no uncontrolled or erroneous movement, thereby ensuring the connection quality and overall performance of the lightweight insulation concrete block.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
