[0036] Please refer to Figures 1-6 , a kind of composite cement foamed insulation board is shown, mainly by thermal insulation board body 1 and be used for connecting thermal insulation board body 1 on the connecting piece 2 on wall.

[0037] Thermal insulation board body 1 is provided with a plurality of connection holes 3, connection hole 3 penetrates the whole thermal insulation board body 1, and the recess 4 for facilitating the installation of the connecting piece 2 is processed at one end of the connection hole 3, the bottom end face of the recess 4 is similar to the structure of the taper, the recess with this special shape can be closely and stably matched with the connecting piece 2, effectively prevent the displacement of thermal insulation board on the wall.

[0038] The connecting piece 2 comprises a pre-embedded piece 201 and a locking piece 202, which are assembled by threaded connection.

[0039] The pre-embedded piece 201 is made of metal material, comprising a connecting rod 201a and a connecting disc 201b fixedly connected with the connecting rod 201a, and the connecting rod 201a and the connecting disc 201b are integrally formed to ensure the structural strength and stability of the pre-embedded piece 201. A threaded hole 201c is formed on the connecting rod 201a, which penetrates the connecting disc 201b to connect with the locking piece 202. Meanwhile, an anti-rotation rib 201d is arranged on the connecting rod 201a, which is fixedly connected with the connecting rod 201a and the connecting disc 201b, and can effectively prevent the pre-embedded piece 201 from rotating during the installation of the locking piece, ensuring the accuracy and firmness of the connection. In addition, a ring gap 201e is arranged on the connecting rod 201a, which can increase the friction coefficient with the cement mortar, and when the pre-embedded piece 201 is embedded in the cement mortar of the wall, it can be more stably fixed inside the wall.

[0040] The locking piece 202 is also made of metal material, comprising a threaded rod 202a and a locking plate 202b matched with the groove 4. The lower end surface of the locking plate 202b is conical, which tightly matches with the similar conical structure of the groove 4. When the locking piece 202 is connected with the pre-embedded piece 201 by threaded connection, with the rotation of the threaded rod 202a, the conical locking plate 202b gradually embeds into the groove 4, generating a strong extrusion force on the insulation board body 1, thereby firmly fixing the insulation board on the wall. The threaded rod 202a is accurately matched with the threaded hole 201c to realize reliable connection. A cross slot 202c is arranged at the end of the locking plate 202b away from the threaded rod 202a for easy locking operation, which can easily rotate the locking piece by means of tools to complete the installation and fixation of the insulation board.

[0041] The connecting piece 2 is provided with multiple pieces, and the number is the same as that of the connecting holes 3, to ensure that the insulation board is evenly stressed on the wall and the connection is stable and reliable. Two rows of connecting holes 3 are arranged on the insulation board body 1, which can optimize the stress distribution of the insulation board and the wall during connection, further improving the stability of the overall connection.

[0042] After the pre-embedded piece 201 is embedded, the side of the connecting disc 201b away from the connecting rod 201a is on the same plane as the wall, which can ensure the flatness of the wall after the installation of the insulation board, and facilitate the subsequent decoration construction and other operations.

[0043] The one side of the insulation board body 1 is provided with the first clamping groove 5 and the first clamping edge 6, and the other side is provided with the second clamping groove 7 and the second clamping edge 8, and the first clamping groove 5 and the second clamping edge 8 are matched, and the first clamping edge 6 and the second clamping groove 7 are matched. Through the ingenious design of the clamping groove and the clamping edge, when multiple insulation boards are spliced and installed, a tight and seamless splicing effect can be achieved, greatly reducing the heat loss at the splicing position and effectively improving the overall insulation performance.

[0044] In addition, the insulation board body 1 is made of a cement foaming forming process. This process can make the insulation board have good insulation performance, light weight and other advantages. In the production process, the density and other parameters can be adjusted according to actual needs to meet the requirements of different construction projects.

[0045] Working principle:

[0046] During the wall construction process, when the wall construction reaches the position where the insulation board needs to be installed, according to the position layout of the connecting hole 3 on the insulation board body 1, the connecting rod 201a of the embedded part 201 is accurately inserted into the wall formwork reserved hole, and then the cement mortar is poured and constructed. During the pouring process, the position of the connecting disc 201b must be strictly controlled to be flush with the surface of the wall, and the anti-turning rib 201d and the ring gap 201e must be fully in contact with the cement mortar. After the cement mortar solidifies, the embedded part 201 is firmly fixed in the wall.

[0047] Then the installation of the insulation board body 1 is carried out. The connecting hole 3 of the insulation board body 1 is aligned with the connecting rod 201a of the embedded part 201, and the insulation board body 1 is tightly attached to the wall. Then the threaded rod 202a of the locking part 202 is screwed into the threaded hole 201c of the embedded part 201, the cross slot 202c of the locking pressure plate 202b is inserted using a suitable tool, and the locking part 202 is slowly rotated. The tapered locking pressure plate 202b gradually embeds into the groove 4 of the connecting hole 3. As the rotation proceeds, the locking pressure plate 202b generates a continuously increasing extrusion force on the insulation board body 1, until the insulation board body 1 is firmly fixed on the wall.

[0048] When multiple insulation boards are spliced and installed, the clamping edge of one insulation board is inserted into the clamping groove of another insulation board, for example, the first clamping edge 6 is inserted into the second clamping groove 7, and the second clamping edge 8 is inserted into the first clamping groove 5. In this way, the splicing and installation of the entire insulation board wall surface are completed. Through this splicing method, the tightness of the splicing between the insulation boards can be effectively guaranteed, the heat transfer path is reduced, and the overall insulation effect is improved.

[0049] The composite cement foamed heat preservation board has the advantages of firm connection, convenient installation and good splicing effect, and can better meet the needs of modern building heat preservation engineering and has wide market application prospect.
