DETAILED DESCRIPTION

[0036] The present invention is described in detail below in conjunction with specific implementation modes.

[0037] like Figure 1 As shown, the present invention includes a wall 100 and a floor slab 200; the wall 100 is provided with a first cork mortar layer 110, a load-bearing structure layer 120 and a phase change layer 130 from the outside to the inside; the floor slab 200 is provided with a floor structure layer 210, a second cork mortar layer 220, a floor heating pipe layer 230 and a first leveling layer 240 from bottom to top.

[0038] like Figure 2As shown, the floor heating pipe layer 230 is provided with a fixing groove 231 near the edge of the wall 100, and the bottom of the phase change layer 130 is located in the fixing groove 231, and the phase change layer 130 is closely attached to the inner wall of the fixing groove 231. The bottom of the phase change layer 130 is fixed, which prevents the bottom of the phase change layer 130 from warping, making the joint between the wall 100 and the floor slab 200 relatively flat, which is convenient for later decoration and decoration.

[0039] The cork cement mortar used to make the first cork mortar layer 110 and the second cork mortar layer 220 is an environmentally friendly building material formed by using cork particles instead of gravel in cement mortar, which has better sound insulation, heat insulation and shockproof effects than traditional cement mortar;

[0040] The phase change layer 130 can release heat when the indoor temperature drops, and absorb heat when the indoor temperature rises, thereby preventing the indoor temperature from changing too much and keeping the indoor temperature stable; the first cork mortar layer 110 can achieve thermal insulation and sound insulation effects, reduce the heat and sound transfer between indoor and outdoor, and greatly reduce the impact of outdoor temperature and sound on the indoor; the second cork mortar layer 220 can achieve thermal insulation and sound insulation effects, reduce the heat and sound transfer between floors, and greatly reduce the impact of floors on the indoor. The second cork mortar layer 220 is located between the floor structure layer 210 and the floor heating pipe layer 230. During winter heating, the second cork mortar layer 220 can block the heat radiation of the floor heating pipe, reduce the heat transferred downward, and increase the heat entering the room from the floor heating pipe, thereby ensuring the heating effect of the floor heating pipe. Therefore, the present invention achieves better thermal insulation and sound insulation effects through the phase change layer 130, the first cork mortar layer 110 and the second cork mortar layer 220;

[0041] In actual use, the sound and vibration transmitted from the upper and lower floors have a great impact on the indoor living experience. In order to achieve better sound insulation and shock absorption effects, the present invention provides a cork cushion layer 250 in the second cork mortar layer 220. Figure 3 shown.

[0042] like Figure 4 As shown, the cork cushion layer 250 includes a plurality of spaced upper convex parts 251 and lower concave parts 252, and a connecting hole 253 is provided at the top of the upper convex part 251 and the bottom of the lower concave part 252; the upper convex part 251 and the lower concave part 252 are spaced in the first direction 300 and the second direction 400 respectively; the first direction 300 is orthogonal to the second direction 400; the upper convex part 251 and the lower concave part 252 are both in the shape of a quadrangular pyramid. The upper convex part 251 and the lower concave part 252 can also be in other shapes, for example, the upper convex part 251 and the lower concave part 252 are both in the shape of a truncated cone.

[0043] The cork cement mortar of the second cork mortar layer 220 can enter the upper protrusion 251, the lower recess 252 and the connecting hole 253, so that the connection between the cork cushion layer 250 and the second cork mortar layer 220 is more firmly connected; and the upper protrusion 251 and the lower recess 252 can weaken the sound and vibration transmitted from all directions, so that the floor 200 as a whole has better sound insulation and shock absorption effects.

[0044] 1) Embodiment 1

[0045] In this embodiment, the phase change layer 130 is formed by phase change thermal insulation mortar.

[0046] After the pouring of the load-bearing structure layer 120 is completed, the phase change thermal insulation mortar is directly coated on the inner side of the load-bearing structure layer 120 to form a phase change layer 130. In addition, the phase change thermal insulation mortar coated on the load-bearing structure layer 120 can penetrate into the micro-voids of the load-bearing structure layer 120, forming a community with the load-bearing structure layer 120, and is not easy to fall off. The phase change thermal insulation mortar is a dry mixed mortar composed of cement, lightweight aggregate loaded with phase change materials and coated, and admixtures. The phase change layer 130 made of phase change thermal insulation mortar has the functions of energy storage, temperature regulation and energy saving, and can effectively control the fluctuation of indoor temperature, improve the thermal insulation performance of the building, and reduce the energy consumption of the building.

[0047] 2) Embodiment 2

[0048] In this embodiment, the phase change layer 130 includes a first protective layer 131, a phase change mortar layer 132 and a second protective layer 133. Figure 5 shown.

[0049] The phase change layer 130 is a prefabricated structure, and is directly installed on the inner side of the load-bearing structure layer 120 using anchor bolts. The phase change mortar layer 132 can control the stability of the indoor temperature by absorbing and releasing heat. The first protective layer 131 and the second protective layer 133 are wooden boards. Since wood is a poor conductor of heat, the first protective layer 131 and the second protective layer 133 can play a good role in heat preservation in the room.

[0050] When manufacturing the phase change layer 130 , the phase change thermal insulation mortar is applied to the first protective layer 131 , and then the second protective layer 133 is covered on the phase change thermal insulation mortar, thereby forming a phase change mortar layer 132 between the first protective layer 131 and the second protective layer 133 .

[0051] like Figure 1 As shown, the wall 100 further includes a second leveling layer 140, which is disposed between the load-bearing structure layer 120 and the phase change layer 130. The second leveling layer 140 is formed of cork cement mortar, so that the second leveling layer 140 can further insulate and soundproof the room while achieving leveling.

[0052] After the load-bearing structure layer 120 is poured, mortar is coated on the inner side of the load-bearing structure layer 120 and scraped flat to form a second leveling layer 140 .

[0053] If the phase change layer 130 is a prefabricated structure of Example 2, the second leveling layer 140 can make the phase change layer 130 better fit the inner side of the load-bearing structure layer 120, and prevent the phase change layer 130 from having a gap with the load-bearing structure layer 120. If the phase change layer 130 is directly formed by applying the phase change thermal insulation mortar to the load-bearing structure layer 120 in Example 1, the second leveling layer 140 can keep the thickness of the phase change layer 130 basically the same at all locations, and then the heat absorption and heat release capabilities of the phase change layer 130 at all locations are basically the same, so that the temperature at all locations in the room can be distributed more evenly.

[0054] like Figure 6 As shown, the construction method of the sound insulation mortar building structure of the present invention comprises the following steps:

[0055] Step 1: construct the load-bearing structure layer 120 and the floor structure layer 210;

[0056] Step 2: Laying cork mortar on the top surface of the floor slab to form a second cork mortar layer 220;

[0057] The second cork mortar layer 220 is used to block the heat and vibration on the upper and lower sides, reduce the heat and sound transfer between floors, and thus make the sound insulation mortar building structure have better thermal insulation and sound insulation effects, greatly reducing the impact of the upper and lower floors on the interior.

[0058] Step 3: Lay the floor heating pipe on the top surface of the second cork mortar layer 220, and cover the floor heating pipe with concrete to form the floor heating pipe layer 230;

[0059] The floor heating pipes in the floor heating pipe layer 230 can radiate heat outwards to keep the indoor temperature at a comfortable level; and the heat radiated outwards by the floor heating pipes is blocked by the second cork mortar layer, thereby avoiding heat waste.

[0060] Step 4: Arrange a first leveling layer 240 on the top surface of the floor heating pipe layer 230;

[0061] Step 5: Lay cork mortar on the outer side of the load-bearing structure layer 120 to form a first cork mortar layer 110, and set a phase change layer 130 on the inner side of the load-bearing structure layer.

[0062] The phase change layer 130 can release heat when the indoor temperature drops and absorb heat when the indoor temperature rises, thereby preventing the indoor temperature from changing too much and keeping the indoor temperature stable. The first cork mortar layer 110 can achieve the effects of heat preservation and sound insulation, reduce the heat and sound transmission between indoor and outdoor, and greatly reduce the impact of outdoor temperature and sound on the indoor.

[0063] The phase change layer 130 can be formed by phase change thermal insulation mortar; the phase change layer 130 is arranged on the inner side of the load-bearing structure layer 120, specifically including: coating the phase change thermal insulation mortar on the inner side of the load-bearing structure layer 120 to form the phase change layer 130.

[0064] The phase change layer 130 can also adopt a prefabricated structure. The phase change layer 130 includes a first protective layer 131, a phase change mortar layer 132 and a second protective layer 133 arranged from the outside to the inside. The phase change mortar layer 132 can control the stability of the indoor temperature by absorbing and releasing heat; the phase change layer 130 can be directly installed on the inner side of the load-bearing structure layer 120 using anchor bolts. The first protective layer 131 and the second protective layer 133 can be wooden boards. Since wood is a poor conductor of heat, the first protective layer 131 and the second protective layer 133 can play a good role in heat preservation in the room. When making the phase change layer 130, the phase change thermal insulation mortar is applied to the first protective layer 131, and then the second protective layer 133 is covered on the phase change thermal insulation mortar, thereby forming a phase change mortar layer 132 between the first protective layer 131 and the second protective layer 133.

[0065] Before step 4, the method further includes: opening a fixing groove 231 at the edge of the floor heating pipe layer 230 close to the load-bearing structure layer 120;

[0066] In step five, a phase change layer 130 is provided on the inner side of the load-bearing structure layer 120, specifically:

[0067] Insert the bottom of the phase change layer 130 into the fixing groove 231, so that the inner side of the phase change layer 130 is close to the inner wall of the fixing groove 231; connect the outer side of the phase change layer 130 to the inner side of the load-bearing structure layer 120;

[0068] The fixing groove 231 fixes the bottom of the phase change layer 130 , thereby preventing the bottom of the phase change layer 130 from warping, making the joint between the wall 100 and the floor slab 200 relatively smooth, and facilitating later decoration and furnishing.

[0069] In step five, before the phase change layer 130 is arranged on the inner side of the load-bearing structure layer 120, the step further includes: inserting the bottom of the second leveling layer 140 into the fixing groove 231, and pressing the outward side of the second leveling layer 140 against the inner side of the load-bearing structure layer 120. Connecting the outward side of the phase change layer 130 to the inner side of the load-bearing structure layer 120 includes: pressing the outward side of the phase change layer 130 against the inward side of the second leveling layer 120.

[0070] If the phase change layer 130 is Figure 3In the prefabricated structure shown, the second leveling layer 140 can make the phase change layer 130 better fit the inner side of the load-bearing structure layer 120, and prevent the phase change layer 130 from having a gap with the load-bearing structure layer 120. If the phase change layer 130 is directly formed by coating the phase change thermal insulation mortar on the load-bearing structure layer 120, the second leveling layer 140 can make the thickness of the phase change layer 130 remain basically the same at all locations, and then the heat absorption and heat release capabilities of the phase change layer 130 at all locations are basically the same, so that the temperature at all locations in the room can be distributed more evenly.

[0071] The second leveling layer 140 is formed of cork cement mortar, so that the second leveling layer 140 can further insulate and soundproof the room while achieving leveling.

[0072] The method further includes: when laying the cork mortar on the top surface of the floor structure layer 210 , arranging the cork cushion layer 250 in the second cork mortar layer 220 , so that the cork cushion layer 250 is located in the second cork mortar layer 220 .

[0073] The cork cushion layer 250 blocks the sound and vibration transmitted from the upper and lower floors, so that the indoor living experience of the soundproof mortar building structure formed by the method is better.
