Referring to fig. 2, the present embodiment provides a thermal insulation and sound insulation roof 2, where the thermal insulation and sound insulation roof 2 includes: support structure layer 21, first puigging 22, keel support layer 23 and insulation 24.
The support structure layer 21 is installed above the wall 3, and the first soundproof layer 22 is laid on the support structure layer 21; the keel supporting layer 23 is arranged above the first sound insulation layer 22, and an installation cavity is formed in the keel supporting layer 23; insulation 24 is filled in the installation cavity.
This application embodiment is through installing support structure layer 21 in the top of wall 3, then in proper order at first puigging 22 of support structure layer 21 top installation and fossil fragments supporting layer 23, forms the installation cavity in the fossil fragments supporting layer 23, and insulation material 24 fills in the installation cavity.

Thereby improving the installation efficiency of the heat-insulating and sound-insulating roof 2 and saving the installation cost.
Further, as shown in fig. 3, the support structure layer 21 of the embodiment of the present application includes a purlin support bracket 211, and the purlin support bracket 211 is installed above the wall 3. If the first soundproof layer 22 is directly attached to the purlin support frame 211, the first soundproof layer 22 itself has low hardness, which causes a problem that the first soundproof layer 22 is likely to collapse. Therefore, the support structure layer 21 of the embodiment of the present application further includes a support plate 212, and the support plate 212 is installed above the purlin support bracket 211. Like this, the backup pad 212 is installed and is provided the loading end for first puigging 22 in purlin support frame 211 top, and purlin support frame 211 can give the effective support that provides in backup pad 212 middle part as the skeleton that supports heat preservation and sound insulation roofing 2 to avoid the emergence of above-mentioned problem.

The support plate 212 may be a general steel plate or a profiled steel plate, and in order to ensure the support strength of the support plate 212, the support plate 212 according to the embodiment of the present invention is a profiled steel plate. Because the profiled steel sheet has light weight, high support strength and good shock resistance, the support strength of the support plate 212 is higher, and the heat-insulating and sound-insulating roof 2 is more stable.
The thermal insulation material 24 may be glass wool or rock wool. The glass wool also has a good sound insulation function, so that the heat insulation material of the heat insulation and sound insulation roof 2 in the embodiment of the application is the glass wool. Thus, the heat-insulating and sound-insulating roof 2 has a good heat-insulating effect, and the sound-insulating effect of the heat-insulating and sound-insulating roof 2 is further improved.
In addition, the purlin support bracket 211 is connected with the support plate 212 through a first fastener. For example, the first fastening member may be a dovetail, a screw, a bolt, etc., and the application is not limited to the specific type of the first fastening member.
Further, as shown in fig. 4, the thermal insulation and sound insulation roof 2 further includes a first thermal insulation layer 25, and the first thermal insulation layer 25 is laid between the first sound insulation layer 22 and the support structure layer 21. Thus, the first heat-insulating layer 25 can further improve the heat-insulating performance of the heat-insulating and sound-insulating roof 2.
In order to ensure that the first thermal insulation layer 25 does not shift above the support structure layer 21, after the first thermal insulation layer 25 is laid between the first soundproof layer 22 and the support structure layer 21, the first soundproof layer 22 and the support structure layer 21 may be connected by the second fastening member. The second fastener may be a self-tapping screw, etc., which is not limited in this application.
Further, as shown in fig. 4, the thermal and acoustical insulation roof 2 further includes a second insulation layer 26, and the second insulation layer 26 is laid between the first acoustical insulation layer 22 and the keel support layer 23. Thus, the second insulating layer 26 can further improve the heat insulating performance of the heat insulating and sound insulating roof 2.
Similarly, in order to ensure that the second insulating layer 26 does not shift, after the second insulating layer 26 is laid between the first soundproof layer 22 and the support structure layer 21, the first soundproof layer 22 and the support structure layer 21 may be connected by a second fastening member.
Both the first insulating layer 25 and the second insulating layer 26 may be a paper-faced gypsum board or a glass mat-faced high-strength fiber-reinforced gypsum board. Because glass mat face high strength fiber reinforced gypsum board is for paper-faced gypsum board, the functions of aspects such as fire prevention, thermal-insulated, sound insulation, shock resistance of glass mat face high strength fiber reinforced gypsum board are all stronger, so, the glass mat face high strength fiber reinforced gypsum board is all adopted to first heat preservation 25 and the second heat preservation 26 of this application embodiment. In this way, the first heat-insulating layer 25 and the second heat-insulating layer 26 can further improve the sound-insulating effect of the heat-insulating and sound-insulating roof 2, and the heat-insulating and sound-insulating roof 2 has impact resistance and fire resistance.

It should be noted that, in order to ensure the connection strength of the thermal insulation and sound insulation roof 2, the support plate 212 may be connected to the first sound insulation layer 22 and the keel support layer 23 by a third fastener. If the insulated roof 2 further includes a first insulation layer 25, a third fastener may join the keel support layer 23, the first insulation layer 22, the first insulation layer 25, and the support plate 212 together. If the insulated roof 2 includes the second layer of insulation 26, a third fastener may join the keel support layer 23, the first layer of insulation 22, and the support plate 212 together. If the insulating and sound-insulating roof 2 includes the first insulating layer 25 and the second insulating layer 26, the third fastening member may couple the keel support layer 23, the second insulating layer 26, the first sound-insulating layer 22, the first insulating layer 25, and the support plate 212 together. Like this, the third fastener can improve the joint strength between each part of heat preservation syllable-dividing roofing 2 is connected, guarantees the overall stability of heat preservation syllable-dividing roofing 2.
It should be noted that, compared to the second fastening member, the third fastening member needs to penetrate through the multi-layer structure of the thermal insulation and sound insulation roof 2 (for example, the keel supporting layer 23, the first sound insulation layer 22 and the supporting plate 212), so that the length of the third fastening member is longer, which can effectively connect the multi-layer structure of the thermal insulation and sound insulation roof 2. The third fastener may be a self-drilling self-tapping screw or a combination self-tapping screw, which is not limited in this application.
Further, as shown in fig. 4, the thermal insulation and sound insulation roof 2 further includes a second sound insulation layer 27, and the second sound insulation layer 27 is laid on the keel supporting layer 23. Thus, the second soundproof layer 27 further improves the soundproof performance of the heat-insulating soundproof roof 2.
Similarly, the thermal and sound insulation roof 2 may further include a third thermal insulation layer 28, and the third thermal insulation layer 28 is laid between the second sound insulation layer 27 and the keel support layer 23. Thus, the third insulating layer 28 further improves the heat insulating effect of the heat insulating and sound insulating roof 2.
Further, as shown in fig. 4, the heat-insulating and sound-insulating roof 2 further includes: a fourth insulating layer 29, the fourth insulating layer 29 being laid over the second soundproof layer 27. Thus, the fourth insulating layer 29 further improves the heat insulating effect of the heat insulating and sound insulating roof 2.
It should be noted that both the third insulation layer 28 and the fourth insulation layer 29 can be a paper-faced gypsum board or a glass mat-faced high-strength fiber-reinforced gypsum board. The third insulating layer 28 and the fourth insulating layer 29 in the embodiment of the present application are both glass-mat-faced high-strength fiber reinforced gypsum boards, for which specific reasons refer to the description of the first insulating layer 25 and the second insulating layer 26, and the description of the present application is omitted here.
In a similar way, in the actual installation process, the heat-insulating and sound-insulating roof 2 can only be provided with the third heat-insulating layer 28, can also only be provided with the fourth heat-insulating layer 29, and can also be provided with the third heat-insulating layer 28 and the fourth heat-insulating layer 29 simultaneously, so that the application is not limited to the above.
In the same way, in order to ensure that the third heat-insulating layer 28 and the fourth heat-insulating layer 29 do not deviate above the keel supporting layer 23, the third heat-insulating layer 28 and the keel supporting layer 23 can be connected through the second fastening piece, and the fourth heat-insulating layer 29, the second sound-insulating layer 28, the third heat-insulating layer 28 and the keel supporting layer 23 can be connected together through the third fastening piece, so that the connection strength between the connection of each part of the heat-insulating and sound-insulating roof 2 can be further improved, and the overall stability of the heat-insulating and sound-insulating roof 2 is ensured.
