Description

Technical Field

[0001] The utility model belongs to the field of building thermal insulation, and in particular relates to an inner sandwich thermal insulation wall structure. Background Art

[0002] The focus of building energy conservation is wall insulation. In the building heat loss, the heat loss of the heat transfer of the envelope structure accounts for 70% to 80%, and the heat loss of the air in the gaps between doors and windows accounts for 20% to 30%. The building exterior wall accounts for the largest proportion in the building envelope structure and is the main part of energy loss. Concrete sandwich insulation wall is an energy-saving and environmentally friendly wall form, which has been promoted. Concrete sandwich insulation wall generally includes a three-layer structure. The concrete layer facing the room is used as a structural support, the inner insulation layer is used for thermal insulation to reduce energy loss, and the concrete layer facing the outside is used as a protective layer or decorative layer.

[0003] During the construction of concrete sandwich insulation wall, formwork is usually set up on both sides of the wall, and concrete is poured in the gap between the insulation layer and the formwork. However, the insulation layer is not in direct contact with the formwork on both sides, and the insulation layer cannot be well supported. When pouring concrete on one side, the insulation layer is prone to dislocation or damage, which reduces the insulation effect of the insulation layer.

[0004] In some areas, a steel cage is set up between the insulation layer and the formwork to support the insulation layer and strengthen the concrete wall structure. However, the thermal conductivity of the steel cage is much greater than that of concrete. The indoor heat is quickly transferred to the outside through the steel cage structure, causing indoor energy loss. In addition, the temperature of the steel cage is inconsistent with that of the concrete. Under the action of thermal expansion and contraction, the steel cage is prone to separation from the concrete, affecting the integrity of the wall. Utility Model Content

[0041] like Figures 1 to 3 As shown, an inner sandwich insulation wall structure includes a first side panel 1, a second side panel 2, and an insulation board 3 located between the first side panel 1 and the second side panel 2, a pouring gap 31 for pouring concrete is provided between the first side panel 1 and the insulation board 3, and between the second side panel 2 and the insulation board 3, a support structure 4 is provided between the first side panel 1 and the insulation board 3, and the support structure 4 includes:

[0042] A support base plate 41, wherein the support base plate 41 comprises a base plate 411 and a raised portion 412 raised relative to the base plate 411 toward the first side plate 1, wherein the base plate 411 abuts against the thermal insulation plate 3; a support member 42, wherein the support member 42 surrounds the raised portion 412, and an isolation gap 311 for pouring concrete exists between the support member 42 and the base plate 411 and the raised portion 412, and the support member 42 abuts against the first side plate 1; a connecting member 43, wherein the connecting member 43 is detachably connected to the support base plate 41 and the support member 42, and the connecting member 43 supports the support base plate 41 and the support member 42.

[0043] It should be noted that the inner sandwich insulation wall structure described in the present invention has an insulation layer formed by an insulation board 3 inside, and concrete walls formed by cast-in-place concrete on both sides.

[0044] The construction steps of the inner sandwich insulation wall structure are:

[0045] S1: erecting the first side plate 1, the insulation plate 3 and the second side plate 2, and using the limiter 5 to support and fix them, so as to form the casting gap 31;

[0046] S2: Use a connecting member 43 to connect the supporting base plate 41 and the supporting member 42 to form the supporting structure 4, and place the supporting structure 4 between the first side plate 1 and the insulation plate 3;

[0047] S3: pouring concrete in the pouring gap 31 between the second side plate 2 and the insulation plate 3, and pouring concrete in the pouring gap 31 between the first side plate 1 and the insulation plate 3 after the concrete is initially set;

[0048] S4: Remove the connecting member 43, continue to erect the first side panel 1, the insulation panel 3, and the second side panel 2 upwards, repeat the above steps, and continue the construction.

[0049] The base plate 411 is in contact with the insulation board 3, the support member 42 is in contact with the first side panel 1, and the connecting member 43 supports the support base plate 41 and the support member 42. When pouring concrete to the pouring gap 31 between the second side panel 2 and the insulation board 3, the support structure 4 supports the insulation board 3, which can limit the displacement of the insulation board 3 toward the first side panel 1, reduce the displacement deviation of the insulation board 3, reduce the tensile damage of the insulation board 3, improve the integrity and completeness of the insulation layer on the insulation wall, and ensure the insulation effect.

[0050] There is an isolation gap 311 for pouring concrete between the support member 42 and the substrate 411 and the protrusion 412. The thermal conductivity of the support member 42 and the support substrate 41 commonly used in construction projects is generally greater than that of the concrete wall. When the support member 42 and the support substrate 41 are in full contact, the support member 42 and the support substrate 41 form a thermal bridge, and the indoor heat can quickly flow to the outdoors through the thermal bridge. In the present utility model, the concrete isolates the support member 42 from the substrate 411 and the protrusion 412, avoids the generation of thermal bridge problems, reduces the conduction of heat through the support member 42 and the substrate 411 and the protrusion 412, reduces heat loss, and improves the thermal insulation effect of the insulation layer. At the same time, it can avoid the problem of separation and cracking between the support member 42, the substrate 411, the protrusion 412 and the concrete due to the large difference in heat between adjacent parts.

[0051] The support member 42 surrounds the protrusion 412, and the protrusion 412 positions the support member 42, which facilitates the assembly of the support structure 4. In addition, the protrusion 412 and the support member 42 reinforce the concrete poured in the isolation gap 311, reducing the occurrence of concrete cracks and deformation.

[0052] It should be noted that the support structure 4 only supports one side of the insulation board 3. Therefore, when pouring the wall, it is necessary to first pour the pouring gap 31 between the second side panel 2 and the insulation board 3. When pouring, the support structure 4 supports the insulation board 3 to prevent displacement and deformation toward the first side panel 1. After the concrete in the pouring gap 31 between the second side panel 2 and the insulation board 3 is initially solidified, the concrete pouring in the pouring gap 31 between the first side panel 1 and the insulation board 3 is performed. The initially solidified concrete wall supports the insulation board 3 to prevent displacement and deformation of the insulation board 3 toward the second side panel 2.

[0053] Preferably, the first side panel 1 faces the indoor direction, and the second side panel 2 faces the outdoor direction. In general concrete sandwich insulation walls, the thickness of the concrete wall facing the indoor direction is relatively large and is a structural wall, while the thickness of the concrete wall facing the outdoor direction is relatively thin and serves to protect the insulation layer or for decoration. That is, the casting gap 31 between the first side panel 1 and the insulation board 3 is relatively large, which facilitates the placement of the support structure 4 in the casting gap 31. At the same time, the thickness of the concrete wall facing the indoor direction is relatively large, and the structure needs to be strengthened more, which plays the structural strengthening role of the support structure 4 and reduces the deformation and cracking of the concrete wall.

[0054] As a preferred embodiment of the present invention, Figures 1 to 3 As shown, the connecting member 43 includes a first fixing portion 431 connected to the substrate 411 and a second fixing portion 432 connected to the support member 42, the second fixing portion 432 is located above the support member 42, the first fixing portion 431 is bent and extended relative to the second fixing portion 432, and the first fixing portion 431 is connected to the side wall of the substrate 411. The first fixing portion 431 is parallel to the wall direction and connected to the side wall of the substrate 411, thereby increasing the connection area between the first fixing portion 431 and the substrate 411 and improving the stability of the support. The first fixing portion 431 is bent and extended relative to the second fixing portion 432, the second fixing portion 432 is parallel to the horizontal plane, and the second fixing portion 432 is located above the support member 42. The support structure 4 is adjusted by adjusting the fixed position of the support member 42 on the second fixing portion 432. In addition, the second fixing portion 432 is parallel to the horizontal plane, thereby increasing the adjustment range of the support structure 4.

[0055] Preferably, Figure 3 As shown, the second fixing portion 432 has a strip hole 4321 that passes through the second fixing portion 432, and the support member 42 is provided with a support protrusion 421, and the support protrusion 421 is located in the strip hole 4321 and can slide along the strip hole 4321, and the sliding direction is perpendicular to the wall surface. The support protrusion 421 slides in the strip hole 4321 perpendicular to the wall surface, and can adjust the distance between the support base plate 41 and the support member 42, so that the support structure 4 can be applied to the casting of insulation walls of various thicknesses, thereby improving the versatility of the support structure 4. The strip hole 4321 also forms a limiting effect on the support protrusion 421, guiding the adjustment operation of the support structure 4, avoiding the misalignment of the protrusion 412 and the support member 42, and reducing the complexity of adjusting the support structure 4.

[0056] Preferably, Figure 1 As shown, the support protrusion 421 is provided with a threaded section and a plurality of support portions 422 sleeved on the threaded section, and the plurality of support portions 422 can clamp and fix the second fixing portion 432 from both sides. The support portion 422 can move spirally on the threaded section, and by adjusting the position of the support portion 422 on the threaded section, the relative height between the connecting member 43 and the supporting member 42 is adjusted, so that the connecting member 43 and the supporting member 42 are more coordinated, the structural interference between the connecting member 43 and the supporting member 42 is reduced, and the convenience of assembling the supporting structure 4 is improved. In addition, the force between the connecting member 43 and the supporting member 42 is made more uniform, and the force stability of the supporting structure 4 is improved. The plurality of support portions 422 can clamp and fix the second fixing portion 432 from both sides, and also improve the stability of the fixing of the connecting member 43 and the supporting member 42.

[0057] Preferably, Figures 1 to 3 As shown, the protrusion 412 is provided with a matching hole 4121 that penetrates the protrusion 412 in a direction parallel to the wall surface, and the matching hole 4121 extends on the protrusion 412 to form a slide groove, and the angle between the extending direction and the horizontal plane is less than 90°, and the support member 42 is provided with an auxiliary rib 423 located in the slide groove. The auxiliary rib 423 is parallel to the wall surface direction and extends in a concrete wall of the insulation wall, forming a reinforcement effect on the concrete wall, which can reduce the bulging deformation of the concrete wall, reduce the force of separation between the concrete wall and the insulation layer, and improve the integrity of the insulation wall.

[0058] In addition, the angle between the extension direction of the chute and the horizontal plane is less than 90°, and the auxiliary rib 423 can also generate a partial displacement perpendicular to the wall when sliding in the chute to adjust the distance between the support base plate 41 and the support member 42. After the connecting member 43 supports and fixes the support base plate 41 and the support member 42, when pouring concrete into the pouring gap 31 between the second side plate 2 and the insulation board 3, the support structure 4 is subjected to an extrusion force perpendicular to the wall, and the auxiliary rib 423 has a horizontal sliding tendency relative to the chute, and the side wall of the chute generates friction resistance to the auxiliary rib 423 to resist relative sliding. The friction resistance generated by the chute and the auxiliary rib 423 bears part of the extrusion force, thereby improving the force stability of the support structure 4.

[0059] The protrusion 412 extends along the wall height direction on the base plate 411, and the support member 42 surrounds the protrusion 412 and extends along the wall height direction. Concrete has poor tensile strength and is easily damaged by external tension. The protrusion 412 and the support member 42 generally have good tensile strength, and are located in the concrete, which can effectively improve the tensile strength of the concrete and improve the overall strength and stability of the insulation wall.

[0060] As a preferred embodiment of the present invention, Figure 4 As shown, the support structure 4 includes a plurality of support substrates 41, and the connecting member 43 connects the plurality of support substrates 41 along the wall surface direction, and the plurality of support substrates 41 are arranged at intervals. The plurality of support substrates 41 support the insulation board 3, thereby increasing the support area of ​​the insulation board 3, reducing the pressure on the insulation board 3, and improving the support stability of the insulation board 3. The plurality of support substrates 41 are arranged at intervals, and after pouring concrete in the pouring gap 31, the concrete contacts a part of the insulation board 3, and the adhesion between the concrete and the insulation board 3 is more stable, thereby improving the adhesion between the multi-layer structure of the insulation wall and improving the integrity of the insulation wall.

[0061] Preferably, Figure 4As shown, the inner sandwich insulation wall structure also includes a limiter 5, the first side panel 1 and the second side panel 2 are both provided with a reserved anchoring groove, the two ends of the limiter 5 are respectively fixed to the reserved anchoring grooves of the first side panel 1 and the second side panel 2, the limiter 5 fixes the first side panel 1 and the second side panel 2, and the limiter 5 is staggered with the support base plate 41. The limiter 5 is staggered with the support base plate 41 to avoid structural interference between the limiter 5 and the support structure 4, and facilitate the operation of inserting the support structure 4 into the casting gap 31. The limiter 5 can fix the first side panel 1 and the second side panel 2, provide a pulling force for the first side panel 1 and the second side panel 2, and offset the pressure generated by pouring concrete. Preferably, the limiter 5 uses a vertical dowel perpendicular to the wall surface to reduce the slenderness ratio of the vertical dowel, so as to reduce the energy dissipation of heat along the vertical dowel.

[0062] As a preferred embodiment of the present invention, Figure 3 As shown, the connector 43 is provided with a grouting positioning hole 4322, the mouth of the grouting positioning hole 4322 extends downward along the wall surface to form a positioning portion, and the grouting pipe is located in the positioning portion. The grouting pipe extends into the casting gap 31 through the positioning portion, determines the casting position, and improves the uniformity of the insulation wall casting. The positioning portion forms a restriction on the grouting pipe, reduces the shaking of the grouting pipe during the casting process, reduces the occurrence of undesirable problems such as uneven concrete casting and concrete segregation, and improves the casting quality of the insulation wall.

[0063] Preferably, the inner sandwich insulation wall structure has a primary pouring height line, and the lower edge of the positioning portion is higher than the primary pouring height line. The upper edge heights of the first side panel 1, the second side panel 2, and the insulation board 3 are higher than the primary pouring height line, which facilitates the overlapping operation of the first side panel 1, the second side panel 2, and the insulation board 3. The lower edge of the positioning portion is higher than the primary pouring height line to increase the pouring pressure during concrete pouring, which can prevent the positioning portion from being poured into the concrete and avoid the inconvenience caused by disassembling the connector 43.
