Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a waterproof upper return structure for an exterior wall of a building with integrated insulation and structure. Background Art

[0002] At present, some areas in my country are actively promoting the integration technology of insulation and structure, that is, the main building envelope structure is rigidly connected with the insulation layer and the outer protective layer through concrete, and the wall structure and the insulation board form a composite insulation wall, thereby realizing the building insulation function and the wall maintenance function in one. This new technology has long durability and is beneficial to the fire protection requirements of the building. The insulation board is integrated with the later poured concrete by inserting anchors in advance.

[0003] In the prior art, silicon plastic composite insulation wall ( Figure 1 ) as an example, the design generally requires that the external wall waterproof layer be returned to 500mm above the splash water elevation. A reinforced concrete supporting eaves is set at the bottom of the silicon-plastic thermal insulation composite board. The silicon-plastic thermal insulation composite board is located on the supporting board. After the silicon-plastic thermal insulation composite board is installed, concrete pouring construction is carried out to make it an integral part of the wall structure. When the underground external wall waterproofing is returned (installed upward) in the later stage, the waterproof layer is glued and fixed to the outside of the silicon-plastic thermal insulation composite board, and the external wall decoration layer is directly constructed on the outside of the waterproof layer.

[0004] However, the problem with the waterproof layer design of the prior art is that since the insulation board and the wall structure are integrally formed, the waterproof layer can only be made on the outside of the insulation layer in the later stage, which makes it impossible for the waterproof layer to be effectively bonded to the wall structure, resulting in the problem of loose fixation, and the waterproof membrane of the exterior wall decoration layer and the waterproof layer cannot be effectively bonded, resulting in cracks in the exterior wall decoration layer at the waterproof end. Summary of the invention

[0005] In view of the defects existing in the prior art, the technical problem solved by the present invention is: how to improve the bonding effect between the waterproof layer and the wall structure in the exterior wall of a building with integrated insulation and structure.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a thermal insulation and structural integrated building exterior wall waterproof upper return structure, comprising: The building exterior wall comprises an above-ground wall structure, an underground wall structure, an overhanging eave and a thermal insulation composite panel, wherein the above-ground wall structure is arranged on the top of the underground wall structure, the overhanging eave is arranged on the outer side of the above-ground wall structure, the thermal insulation composite panel is anchored on the outer side of the above-ground wall structure, and the thermal insulation composite panel is arranged on the top surface of the overhanging eave; The waterproofing membrane is laid on the outer side of the underground wall structure and the outer side of the above-ground wall structure under the overhanging eaves, and is laid on the bottom surface, outer side surface and top surface of the overhanging eaves, and the membrane end structure of the waterproofing membrane is located on the top surface of the overhanging eaves; A first thermal insulation layer is provided between the waterproof coiled material and the thermal insulation composite board, and is provided on the outer side of the overhanging eaves; The second thermal insulation layer is arranged on the outer side of the waterproof membrane between the eaves and the underground wall structure.

[0007] By adopting the above technical scheme, when the exterior wall of the building is an integrated wall with insulation and structure, the waterproof membrane end structure can be set on the top surface of the eaves, and then the setting position of the eaves on the ground wall structure is adjusted to change the laying height of the waterproof membrane, so that the waterproof height can reach 500mm above the water level, and the waterproof membrane can be directly connected to the wall structure, thereby improving the bonding effect between the waterproof layer and the wall structure in the exterior wall of the building with insulation and structure. At the same time, the exterior wall decoration layer will not be directly connected to the waterproof membrane, thereby solving the problem of cracking of the exterior wall decoration layer at the waterproof end.

[0008] In combination with the first aspect, in one embodiment, a water dispersion slope is provided on the outer side surface of the junction of the above-ground wall structure and the underground wall structure, which includes an upper water dispersion slope and a lower water dispersion slope, and the upper water dispersion slope is arranged on the top surface of the lower water dispersion slope, and the top surface of the upper water dispersion slope is against the bottom surface of the second insulation layer.

[0009] By adopting the above technical solution, a large amount of water accumulation at the junction of the above-ground wall structure and the underground wall structure can be avoided, thereby reducing the probability of water seepage at the junction.

[0010] In one embodiment, a waterproof protective layer is provided between the lower layer of the water-spreading slope and the waterproof coiled material, and a waterproof protective layer is provided between the upper layer of the water-spreading slope and the waterproof coiled material.

[0011] By adopting the above technical solution, it is possible to avoid direct contact between the water dispersion slope and the waterproof membrane, which would cause damage to the waterproof membrane and reduce the waterproof effect.

[0012] In one embodiment, a sealing component is provided between the upper water dispersion slope and the second thermal insulation layer; And / or, a sealing component is provided between the upper diffusive slope and the waterproof protective layer.

[0013] By adopting the above technical solution, there is a gap between the upper water dispersion slope and the second insulation layer, and there is also a gap between the upper water dispersion slope and the waterproof protective layer. Therefore, a sealing component is arranged in the gap to reduce the probability of water seepage at this position.

[0014] In one embodiment, the coil end structure includes an end end groove and an end end piece. The end end groove is opened on the top surface of the eaves. One end of the end end piece is connected to the waterproof coil, and the other end thereof is embedded in the end end groove.

[0015] By adopting the above technical solution, the end-sealing method of the waterproof membrane of this design can avoid direct contact between the waterproof membrane and the exterior wall decoration layer, thereby avoiding cracking of the exterior wall decoration layer at the end-sealing part of the waterproof membrane.

[0016] In one embodiment, the coil end structure includes an end groove and an end piece. The end groove is opened on the first insulation layer. One end of the end piece is connected to the waterproof coil, and the other end thereof is embedded in the end groove.

[0017] By adopting the above technical solution, the end-sealing method of the waterproof membrane of this design can avoid direct contact between the waterproof membrane and the exterior wall decoration layer, thereby avoiding cracking of the exterior wall decoration layer at the end-sealing part of the waterproof membrane.

[0018] In one embodiment, the end cap includes an end cap body, a roll material inlet is provided at the bottom of the end cap body, a first sealing member is provided at the roll material inlet, and the first sealing member is located between the waterproof roll material and the end cap body; The inner wall of the head body is provided with a slide rail, and a first slide plate and a second slide plate are movably provided on the slide rail, the first slide plate is located at the bottom of the second slide plate, and a first rebound assembly is provided between the first slide plate and the second slide plate, and a driving member is provided at one end of the first slide plate and the second slide plate respectively, and the driving member is provided on the head body; The bottom surface of the first slide plate and the inner bottom surface of the end body are respectively provided with bite teeth, the two sets of bite teeth are bite-connected, and the waterproof coiled material is located between the two sets of bite teeth; A support frame is provided on the top surface of the second slide plate, and a second rebound assembly is provided at both ends of the support frame, one end of the second rebound assembly is fixedly connected to the second rebound assembly, and an anti-drop rod is provided at the other end thereof, and an end of the anti-drop rod away from the second rebound assembly abuts against the inner wall of the head body, and an anti-drop groove is provided on the top of the head body, which is used to extend the anti-drop rod; A second sealing member is sleeved on the outer wall of the end body between the driving member of the second slide plate and the anti-slip groove.

[0019] By adopting the above technical solution, the tail of the waterproof roll is placed inside the head body from the roll entrance. Before placement, the driving member of the first slide can be pushed upward to drive the first slide to move upward along the slide rail, and the two sets of bite teeth are separated from each other. After placement, the first rebound component drives the first slide to move downward along the slide rail until the two sets of bite teeth are engaged, so that the waterproof roll is fixed between the two sets of bite teeth, and when the two sets of bite teeth are engaged, the first slide cannot move downward any further, thereby playing a role in limiting the first slide. A first sealing member is inserted into the gap of the roll material entrance, so as to prevent water from penetrating into the end body and further strengthen the firmness of the fixing between the waterproof roll material and the end body; Before placing the head piece in the head slot, the driving member of the second slide plate can be pushed downward to drive the second slide plate to move downward along the slide rail, so that the anti-dropping rod is retracted into the interior of the head body and moves downward along the inner wall of the head body. After the head piece is placed in the head slot, the first rebound assembly drives the first slide plate to move upward along the slide rail. When the end of the anti-dropping rod moves to the anti-dropping slot, the anti-dropping rod is extended from the anti-dropping slot due to the outward thrust of the second rebound assembly on the anti-dropping rod. Since the anti-dropping slot is tilted downward, the anti-dropping rod is obliquely inserted into the inner wall of the head slot, thereby preventing the head piece from falling off from the inside of the head slot. On the one hand, the second sealing member can prevent water from penetrating to the top of the head body; on the other hand, it can increase the friction between the head body and the inner wall of the head groove, thereby further strengthening the firmness of the fixation between the head body and the head groove; on the third hand, the driving member of the second slide plate will collide with the second sealing member when moving upward, thereby limiting the second slide plate.

[0020] In one embodiment, a composite waterproof layer is arranged between the thermal insulation composite board and the first thermal insulation layer, and the composite waterproof layer is arranged on the outer side of the thermal insulation composite board. The composite waterproof layer includes a waterproof mortar layer and a JS waterproof layer, and the JS waterproof layer is arranged on the outer side of the waterproof mortar layer.

[0021] By adopting the above technical solution, if the waterproof elevation of the waterproof membrane is not enough to 500mm, the design height of the waterproof layer needs to be increased. However, at this time, the building exterior wall and the thermal insulation composite board on the upper part of the waterproof membrane have been integrated, and it is necessary to avoid that the waterproof layer cannot be directly connected to the wall structure, resulting in reduced bonding effect. Therefore, the composite waterproof layer is laid in the gap between the thermal insulation composite board and the first thermal insulation layer, and on the thermal insulation composite board to meet the height requirement of 500mm.

[0022] In a second aspect, the present invention provides a method for constructing a waterproof upper return structure for an exterior wall of a building with thermal insulation and structural integration, comprising the following steps: The thermal insulation composite panel is installed on the supporting board of the overhanging eaves, and concrete is poured in the preset area to form the thermal insulation composite panel and the building exterior wall into one piece; Lay the waterproofing membrane from the bottom of the underground wall structure upward until it reaches the top surface of the overhanging eaves, and set a membrane end structure at the end of the waterproofing membrane; A water dispersion slope is built on the bottom surface, wherein one end of the water dispersion slope abuts against the waterproof membrane; An insulation layer is laid on the portion of the waterproof membrane exposed to the air, wherein the insulation layer includes a first insulation layer and a second insulation layer, the first insulation layer is arranged between the waterproof membrane and the insulation composite board, and is arranged on the outer side of the eaves, and the second insulation layer is arranged on the outer side of the waterproof membrane between the eaves and the splash slope.

[0023] By adopting the above technical scheme, when the exterior wall of the building is an integrated wall with insulation and structure, the roll end structure of the waterproof roll can be set on the top surface of the eaves, and then the setting position of the eaves on the ground wall structure is adjusted to change the laying height of the waterproof roll. Therefore, the waterproof height can be met to reach 500mm above the splash height, and the waterproof roll can be directly connected to the wall structure, thereby improving the bonding effect between the waterproof layer and the wall structure in the exterior wall of the building with insulation and structure.

[0024] In conjunction with the second aspect, in one embodiment, the construction method of the thermal insulation and structural integrated building exterior wall waterproof return structure further includes: Determine whether the height difference between the top surface of the cantilevered eaves and the top surface of the water spillway is less than 500mm; If yes, apply waterproof mortar from the coil end structure along the space between the thermal insulation composite board and the first thermal insulation layer and the open side of the thermal insulation composite board until the height difference between the highest point of the waterproof mortar and the top surface of the cantilevered eaves is greater than or equal to 500mm; after the waterproof mortar is finally set, apply JS waterproof coating on the waterproof mortar; Otherwise, no further processing is performed.

[0025] By adopting the above technical solution, the waterproof layer that meets the standard does not need other treatment, and a composite waterproof layer is made for the waterproof layer that does not meet the standard, so that the entire waterproof layer meets the standard requirements, and the added composite waterproof layer does not have the problem of poor bonding with the wall structure.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects: 1. Under the condition that the waterproof height meets the standard, the waterproof membrane can be directly connected to the wall structure, thereby improving the bonding effect between the waterproof layer and the wall structure in the exterior wall of the building with integrated insulation and structure; 2. Avoid direct contact with the exterior wall decoration layer to solve the problem of cracking of the exterior wall decoration layer at the end of the waterproof membrane; 3. By adding a composite waterproof layer, the waterproof elevation can reach the standard height without affecting the bonding effect between the waterproof layer and the wall structure.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0030] The waterproof upper return structure of the building exterior wall with integrated insulation and structure in the embodiment of the present invention.

[0031] Example 1 See also Figure 2 As shown, the thermal insulation and structural integrated building exterior wall waterproof upper return structure includes a building exterior wall, which includes an above-ground wall structure 1, an underground wall structure 2, an overhanging eave 3 and an insulation composite board 4. The above-ground wall structure 1 is arranged on the top of the underground wall structure 2, and the overhanging eave 3 is arranged on the outer side of the above-ground wall structure 1, and the top surface height of the overhanging eave 3 exceeds the scattered water elevation h, h is 500mm, and the insulation composite board 4 is anchored to the outer side of the above-ground wall structure 1 through an anchor 5, and the insulation composite board 4 is arranged on the overhanging eave 3; the outer side surface of the underground wall structure 2 and the outer side surface of the above-ground wall structure 1 under the eaves 3 are paved with a waterproof membrane 6, and the waterproof membrane 6 is laid on the bottom surface, outer side surface and top surface of the eaves 3, and the membrane end structure of the waterproof membrane 6 is located on the top surface of the eaves 3; a first insulation layer 7 is arranged between the waterproof membrane 6 and the thermal insulation composite panel 4, and the first insulation layer 7 is arranged on the outer side surface of the eaves 3; a second insulation layer 8 is arranged on the outer side surface of the waterproof membrane 6 between the eaves 3 and the underground wall structure 2.

[0032] It can be seen that the present invention sets the eaves 3 on the outer side of the above-ground wall structure 1, and the top surface height of the eaves 3 exceeds the water dispersion elevation of 500mm. The waterproof membrane 6 is laid along the outer side of the underground wall structure 2 and the outer side of the above-ground wall structure 1 under the eaves 3, the bottom surface, outer side surface and top surface of the eaves 3, and a membrane end structure is set on the top surface of the eaves 3 to prevent water from seeping into the wall structure from the gap between the eaves 3 and the waterproof membrane 6. Because the top surface height of the eaves 3 exceeds the water dispersion elevation of 500mm, the design height of the waterproof membrane 6 exceeds the water dispersion elevation of 500mm, that is, it meets the waterproof height requirement. The waterproof membrane 6 can be directly connected to the wall structure, thereby improving the bonding effect between the waterproof layer and the wall structure in the exterior wall of the building with integrated insulation and structure.

[0033] Preferably, a water dispersion slope is provided on the outer side surface at the junction of the above-ground wall structure 1 and the underground wall structure 2, which includes an upper water dispersion slope 11 and a lower water dispersion slope 12. The upper water dispersion slope 11 is arranged on the top surface of the lower water dispersion slope 12, and the top surface of the upper water dispersion slope 11 is against the bottom surface of the second insulation layer 8.

[0034] It should be noted that it is an existing technology to set a water dispersion slope on the outer side surface of the junction of the above-ground wall structure 1 and the underground wall structure 2, and the above-mentioned solution has made further improvements to the water dispersion slope.

[0035] Specifically, the water dispersion slope is divided into two layers, the upper and lower layers, which improves the water dispersion of the water dispersion slope, thereby reducing the probability of water seepage in the wall structure due to water accumulation. At the same time, the top surface of the designed upper water dispersion slope 11 is against the bottom surface of the second insulation layer 8, avoiding the waterproof membrane 6 from being exposed, resulting in damage to the waterproof membrane 6, thereby reducing the waterproof performance of the wall structure.

[0036] Furthermore, a waterproof protective layer 10 is provided between the lower water-spreading slope 12 and the waterproof coiled material 6 , and a waterproof protective layer 10 is provided between the upper water-spreading slope 11 and the waterproof coiled material 6 .

[0037] Specifically, in order to avoid direct contact between the water dispersion slope and the waterproof membrane 6, which would cause damage to the waterproof membrane 6 and reduce the waterproof effect, a waterproof protective layer 10 is provided on the outer side of the waterproof membrane 6. The material of the waterproof protective layer 10 can be cement mortar, fine stone concrete, quartz sand layer, concrete precast board, etc.

[0038] Furthermore, a sealing component 9 is provided between the upper water dispersion slope 11 and the second thermal insulation layer 8; Alternatively, a sealing component 9 is provided between the upper water dispersion slope 11 and the waterproof protection layer 10; Alternatively, sealing components 9 are provided between the upper water-spreading slope 11 and the second thermal insulation layer 8 and between the upper water-spreading slope 11 and the waterproof protection layer 10. The two sets of sealing components 9 may be integrated or separated.

[0039] Specifically, there is a gap between the upper water-dispersing slope 11 and the second thermal insulation layer 8 through which water can penetrate, so a sealing component 9 is arranged there. The sealing component 9 can occupy all the contact surfaces between the upper water-dispersing slope 11 and the second thermal insulation layer 8, or can occupy part of the contact surfaces between the upper water-dispersing slope 11 and the second thermal insulation layer 8, as long as it is satisfied that water does not penetrate inward; the design principle of the sealing component 9 arranged between the upper water-dispersing slope 11 and the waterproof protective layer 10 is the same as described above, so it does not matter whether it is designed there or not. Preferably, a sealing component 9 is arranged between the upper water-dispersing slope 11 and the second thermal insulation layer 8, and between the upper water-dispersing slope 11 and the waterproof protective layer 10, and the two groups of sealing components 9 are integrated. This solution has a better sealing effect.

[0040] Preferably, a specific structure of a coil end structure is provided: The coiled material end structure includes an end groove 62 and an end piece 61 . The end groove 62 is opened on the top surface of the overhanging eaves 3 . One end of the end piece 61 is connected to the waterproof coiled material 6 , and the other end thereof is embedded in the end groove 62 .

[0041] Specifically, when laying the waterproof membrane 6, it is necessary to open an end groove 62 on the top surface of the eaves 3. When the waterproof membrane 6 is laid to the end groove 62, the laying work is stopped, and one end of the end piece 61 is connected to the waterproof membrane 6, and the other end is embedded in the end groove 62. The smaller the gap between the end piece 61 and the end groove 62, the better, to ensure the sealing of the end point and avoid water seepage at the end point. At the same time, the first insulation layer 7 between the waterproof membrane 6 and the thermal insulation composite board 4 occupies space, and there is a risk of water penetrating into the wall structure. Therefore, it is necessary to supplement the waterproofing of this area with the waterproof membrane 6 to further improve the waterproof performance of the wall structure.

[0042] Preferably, another specific structure of the coil end structure is provided: The coiled material end structure includes an end groove 62 and an end piece 61 . The end groove 62 is opened on the first thermal insulation layer 7 . One end of the end piece 61 is connected to the waterproof coiled material 6 , and the other end thereof is embedded in the end groove 62 .

[0043] Specifically, when laying the waterproof membrane 6, it is necessary to open an end groove 62 in the first insulation layer 7. When the waterproof membrane 6 is laid to the end groove 62, the laying work is stopped, and one end of the end piece 61 is connected to the waterproof membrane 6, and the other end is embedded in the end groove 62. The smaller the gap between the end piece 61 and the end groove 62, the better, to ensure the sealing of the end and avoid water seepage at the end. Compared with the first design, this design reduces the construction steps, but the disadvantage is that the stability of the end of the waterproof membrane 6 is worse than the first design. The end solution can be selected according to actual needs.

[0044] Furthermore, a specific structure of a terminal 61 is provided: The end cap 61 includes an end cap body 611, a roll material inlet is provided at the bottom of the end cap body 611, a first sealing member 613 is provided at the roll material inlet, and the first sealing member 613 is located between the waterproof roll material 6 and the end cap body 611; The inner wall of the head body 611 is provided with a slide rail 617, and the slide rail 617 is movably provided with a first slide plate 614 and a second slide plate 618, the first slide plate 614 is located at the bottom of the second slide plate 618, and a first rebound assembly 616 is provided between the first slide plate 614 and the second slide plate 618, and one end of the first slide plate 614 and the second slide plate 618 is respectively provided with a driving member 615, and the driving member 615 is provided on the head body 611; The bottom surface of the first slide plate 614 and the inner bottom surface of the end body 611 are respectively provided with bite teeth 612, and the two sets of bite teeth 612 are bite-connected, and the waterproof membrane 6 is located between the two sets of bite teeth 612; A support frame 6110 is provided on the top surface of the second slide plate 618, and second rebound components 6111 are provided at both ends of the support frame 6110. One end of the second rebound component 6111 is fixedly connected to the second rebound component 6111, and the other end thereof is provided with an anti-drop rod 6112. One end of the anti-drop rod 6112 away from the second rebound component 6111 abuts against the inner wall of the head body 611, and the top of the head body 611 is provided with an anti-drop groove 6113 for extending the anti-drop rod 6112. A second sealing member 619 is sleeved on the outer wall of the end body 611 between the driving member 615 of the second slide plate 618 and the anti-slip groove 6113 .

[0045] Specifically, the tail of the waterproof roll 6 is placed inside the end body 611 from the roll entrance. Before placement, the driving member 615 of the first slide plate 614 can be pushed upward to drive the first slide plate 614 to move upward along the slide rail 617, and the two sets of bite teeth 612 are separated from each other. After placement, the first rebound component 616 drives the first slide plate 614 to move downward along the slide rail 617 until the two sets of bite teeth 612 are engaged, so that the waterproof roll 6 is fixed between the two sets of bite teeth 612. When the two sets of bite teeth 612 are engaged, the first slide plate 614 cannot continue to move downward, thereby limiting the first slide plate 614. A first sealing member 613 is inserted into the gap at the entrance of the roll material, which prevents water from penetrating into the end body 611 and further strengthens the firmness of the fixing between the waterproof roll material 6 and the end body 611; Before placing the head receiving member 61 in the head receiving groove 62, the driving member 615 of the second slide plate 618 can be pushed downward to drive the second slide plate 618 to move downward along the slide rail 617, thereby driving the support frame 6110 to move downward. Since one end of the second rebound component 6111 is fixed to the support frame 6110, the anti-drop rod 6112 is retracted into the interior of the head receiving body 611 and moves downward along the inner wall of the head receiving body 611. At this time, the second rebound component 6111 is in a contracted state. When the anti-drop rod 6112 moves downward, the anti-drop rod 6112 is driven to move downward. 112 abuts against the inner wall of the head receiving body, after the head receiving member 61 is placed inside the head receiving groove 62, the first rebound component 616 drives the first slide plate 614 to move upward along the slide rail 617, and when the end of the anti-dropping rod 6112 moves to the anti-dropping groove 6113, due to the outward thrust of the second rebound component 6111 on the anti-dropping rod 6112, the anti-dropping rod 6112 extends out of the anti-dropping groove 6113, and since the anti-dropping groove 6113 is tilted downward, the anti-dropping rod 6112 is obliquely inserted into the inner wall of the head receiving groove 62, thereby preventing the head receiving member 61 from falling off from the inside of the head receiving groove 62; The second sealing member 619 can prevent water from penetrating to the top of the head body 611, and can increase the friction between the head body 611 and the inner wall of the head groove 62, thereby further strengthening the firmness of the fixation between the head body 611 and the head groove 62. Thirdly, the driving member 615 of the second slide plate 618 will collide with the second sealing member 619 when moving upward, thereby limiting the second slide plate 618. Therefore, compared with the end of the waterproof membrane 6 in the prior art, the design of the above-mentioned end piece 61 can not only fix the tail of the waterproof membrane 6, but also improve the waterproof performance of the end, and also improve the stability of the fixation between the end piece 61 and the end groove 62.

[0048] Specifically, additional waterproofing measures are required at the end of the waterproof membrane 6 to the scattered water level of 500mm, but the thermal insulation composite board 4 on the upper part of the waterproof membrane 6 has been integrally formed with the wall structure, so the waterproof membrane 6 cannot be laid in the gap between the two, and it is necessary to avoid the problem that the waterproof layer cannot be effectively bonded to the wall structure, resulting in loose fixation. Therefore, additional waterproofing measures are required until the scattered water level reaches 500mm, and a double-layer waterproofing measure of a waterproof mortar layer and a JS waterproof layer (polymer cement waterproof layer) is adopted. The waterproof layer can be directly applied to the thermal insulation composite board 4 to waterproof the wall structure.

[0049] It should be noted that why the above-mentioned composite waterproof layer 13 is not used for the entire wall structure is because the waterproof performance of the composite waterproof layer 13 is not as good as the waterproof performance of the waterproof membrane 6, and the composite waterproof layer 13 can only be used for the above-ground wall structure 1. Because the accumulated water on the ground will seep into the underground, the waterproof requirements of the underground wall structure 2 are higher, and the composite waterproof layer 13 cannot meet the requirements.

[0050] Furthermore, on the basis of the composite waterproof layer 13, a specific structure of a coiled material end structure is provided: The coil end structure of the waterproof coil 6 can be changed to the outer side of the eaves 3. The composite waterproof layer 13 is located between the waterproof coil 6 and the first thermal insulation layer 7. The coil end structure includes an end groove 62 and an end piece 61. The end groove 62 is opened on the outer side of the eaves 3. One end of the end piece 61 is connected to the waterproof coil 6, and the other end thereof is embedded in the end groove 62. The end piece 61 and the composite waterproof layer 13 are sealed by a building paste 63.

[0051] Specifically, because the waterproof membrane 6 has its end structure moved to the outer side of the cantilever eave 3, it is necessary to further install a sealant and ensure the gaps between the structures to prevent water from penetrating into the wall structure.

[0052] The construction method of the thermal insulation and structural integrated building exterior wall waterproof upper return structure in the embodiment of the present invention comprises the following steps: The thermal insulation composite panel 4 is erected on the supporting plate of the overhanging eaves 3, and concrete is poured in the preset area so that the thermal insulation composite panel 4 and the building exterior wall are formed into one piece; Lay the waterproofing coiled material 6 from the bottom of the underground wall structure 2 upward until it reaches the top surface of the overhanging eaves 3, and set a coiled material end structure at the tail of the waterproofing coiled material 6; Build a water dispersion slope on the ground, wherein one end of the water dispersion slope abuts against the waterproof membrane 6; An insulation layer is laid on the portion where the waterproof membrane 6 is exposed to the air, wherein the insulation layer includes a first insulation layer 7 and a second insulation layer 8. The first insulation layer 7 is arranged between the waterproof membrane 6 and the insulation composite board 4, and is arranged on the outer side of the eaves 3. The second insulation layer 8 is arranged on the outer side of the waterproof membrane 6 between the eaves 3 and the water dispersion slope.

[0053] Specifically, when the exterior wall of the building is an integrated insulation and structural wall, the end structure of the waterproof membrane 6 can be set on the top surface of the eaves 3, and then the laying height of the waterproof membrane 6 can be changed by adjusting the setting position of the eaves 3 on the ground wall structure 1, so that the waterproof height can reach 500mm above the water level, and the waterproof membrane 6 can be directly connected to the wall structure, thereby improving the bonding effect between the waterproof layer and the wall structure in the exterior wall of the building with integrated insulation and structure.

[0054] Preferably, the construction method of the waterproof upper return structure of the exterior wall of the thermal insulation and structural integration building also includes: Determine whether the height difference between the top surface of the overhanging eave 3 and the top surface of the water spillway is less than 500mm; If yes, apply waterproof mortar from the coil end structure along the open side of the thermal insulation composite board 4 between the thermal insulation layer 7 and the first thermal insulation layer 7 until the height difference between the highest point of the waterproof mortar and the top surface of the cantilever 3 is greater than or equal to 500mm; after the waterproof mortar is finally set, apply JS waterproof coating on the waterproof mortar; Otherwise, no further processing is performed.

[0055] Specifically, if the height difference between the top surface of the overhanging eaves 3 and the top surface of the water sprinkling slope is less than 500mm, additional waterproofing measures are required at the end of the waterproof membrane 6 to the water sprinkling elevation of 500mm, but the thermal insulation composite board 4 on the top of the waterproof membrane 6 has been integrally formed with the wall structure, so the waterproof membrane 6 cannot be laid in the gap between the two, and it is necessary to avoid the problem that the waterproof layer cannot be effectively bonded to the wall structure, resulting in loose fixation. Therefore, additional waterproofing measures are required until the water sprinkling elevation of 500mm is reached, and a double-layer waterproofing measure of a waterproof mortar layer and a JS waterproof layer (polymer cement waterproof layer) is adopted. The waterproof layer can be directly applied to the thermal insulation composite board 4 to waterproof the wall structure; if the height difference between the top surface of the overhanging eaves 3 and the top surface of the water sprinkling slope is not less than 500mm, the waterproof membrane 6 can be directly laid to the top surface of the overhanging eaves 3, and no other treatment is required.

[0056] Preferably, a thermal insulation layer is laid at a location where the waterproof coiled material 6 is exposed to the air, specifically comprising: Insulation mortar is laid between the waterproof membrane 6 and the insulation composite board 4 and on the outer side of the eaves 3; An extruded board is laid on the outer side of the waterproof membrane 6 between the overhanging eaves 3 and the water dispersion slope.

[0057] Specifically, the first insulation layer 7 is made of insulation mortar, which has a better effect as a thinner insulation layer; the second insulation layer 8 is made of extruded board, which is adhered to the waterproof membrane 6 in this area.

[0058] It should be noted that extruded boards can be replaced by other insulation layers, such as rock wool, expanded clay concrete, foam mortar, etc.
