Description

Technical Field

[0001] This application relates to the technical field of prefabricated wall structures, and in particular to a prefabricated composite building double-skin exterior wall structure and its construction method. Background Technology

[0002] The precast composite building double-skin wall structure, also known as a double-skin wall structure or composite slab shear wall, is, as the name suggests, composed of two "pieces" of concrete wall panels stacked together. The stacking is achieved by steel trusses connecting the two concrete panels. During factory prefabrication, cavities exist between the panels. After on-site installation, concrete is poured into these cavities. The resulting precast and cast-in-place concrete integrally load-bearing wall is the composite slab shear wall.

[0003] In existing double-skin wall systems, the outer panels of the main body at corner joints are often cantilevered, making them susceptible to damage during transport. To address this issue, invention patent CN113006315A discloses a double-skin wall system that uses protective panels to safeguard the outer panels during transport and creates a seal at the corner joints of the two double-skin walls during construction, facilitating subsequent concrete pouring.

[0004] However, in the above solution, there is only one protective plate on the outer side of the two double-layer walls at the corner connection. This means that during transportation, the outer layer of one double-layer wall is not protected by a protective plate, or the protective plate on one double-layer wall needs to be removed during construction. Furthermore, the two double-layer walls at the corner connection only have a protective plate on the outer side for sealing, so the sealing performance on the inner side is poor.

[0005] Given the above situation, it is clear that there is still considerable room for improvement in the double-skin wall structure at the corner connection. Summary of the Invention

[0006] This application provides an assembled composite building double-skin exterior wall structure and its construction method, which facilitates construction, better protects the outer panels of the double-skin wall body during transportation, and comprehensively improves the sealing of corner joints, thereby further facilitating subsequent concrete pouring construction.

[0007] On the one hand, this application provides an assembled composite building double-skin exterior wall structure, adopting the following technical solution:

[0008] An assembled composite building double-skin exterior wall structure includes a double-skin wall body and protective components;

[0009] The double-layer wall body includes an outer layer, an inner layer, and a steel reinforcement structure. The outer layer and the inner layer are parallel to each other. Both ends of the steel reinforcement structure are fixedly connected to the outer layer and the inner layer, respectively, and one end of the outer layer extends out relative to the inner layer.

[0010] The protective assembly includes a first plate, a second plate, a base, and several positioning elements. The two ends of the first plate are rotatably connected to the second plate and the base, respectively, and the two rotation axes are parallel to each other. The outer plate and the inner plate have positions for the base to be installed at the corner connection of the double-layer wall body. The several positioning elements are respectively disposed at the rotational connection between the first plate and the second plate and at the rotational connection between the first plate and the base, and the several positioning elements respectively restrict the relative rotation between the first plate and the second plate and the relative rotation between the first plate and the base.

[0011] By adopting the above technical solution, before transporting the main body of the double-layer wall, adjusting the installation position of the base and the rotation position of the first and second plates allows the first and second plates to enclose one end of the main body of the double-layer wall, providing protection for the cantilevered portion of the outer sheet. During the construction of the main body of the double-layer wall, adjusting the installation position of the base and the rotation position of the first and second plates allows the first plate to fit snugly against the main body of the double-layer wall, and the second plate to fit snugly against the other main body of the double-layer wall. This facilitates determining the hoisting position of the two main bodies of the double-layer wall and improves the hoisting quality. At the same time, the two protective components will seal the inner and outer sides of the corner connection between the two main bodies of the double-layer wall, thereby further facilitating subsequent concrete pouring and improving the effect of subsequent concrete pouring.

[0012] Optionally, the protective assembly further includes a positioning seat, one end of which is rotatably connected to the end of the second plate away from the first plate. The rotation axis of the positioning seat relative to the second plate is parallel to the rotation axis of the second plate relative to the first plate. The outer plate and the inner plate near the corner connection of the double-wall body each have a position for positioning by the positioning seat, and the rotation of the positioning seat relative to the second plate is also restricted by the positioning element.

[0013] By adopting the above technical solution, the end of the second plate away from the first plate is connected and fixed to the double-wall body through the positioning seat, thereby improving the relative positional stability between the protective component and the double-wall body, and thus improving the protective and sealing effect of the protective component on the double-wall body.

[0014] Optionally, the protective assembly further includes a fixing base, an adjusting bolt, and several guide members. The outer and inner leaf plates each have a position for the fixing base to be fixedly installed at one end near the corner connection of the double-layer wall body. The base is slidably connected to the corresponding outer or inner leaf plate. The tail of the adjusting bolt is rotatably connected to the base, and the rotation axis of the adjusting bolt is parallel to the sliding direction of the base. The adjusting bolt passes through the fixing base and is threaded into it. One end of the guide member is connected to the base and passes through the fixing base, and the guide member is parallel to the adjusting bolt.

[0015] By adopting the above technical solution, during the construction of the double-wall body, rotating the adjusting bolt can drive the base to slide and change its installation position on the double-wall body, thereby reducing the construction difficulty. In addition, when the second plate plays an auxiliary hoisting role for the other double-wall body, during the process of controlling the base to slide towards the fixed seat, the second plate can not only check whether the hoisting position of the other double-wall body is appropriate, but also have a corrective effect on the other double-wall body with an inappropriate hoisting position.

[0016] Optionally, the protective assembly further includes a seal and a pressing member. The seal is disposed inside the first plate and slidably connected to the first plate. The pressing member is disposed inside the base and slidably connected to the base. The pressing member slides in and out of both ends of the base along the sliding direction of the base, and the seal slides in and out of both ends of the first plate. When the base and the first plate are in the same plane, when the pressing member slides to its limit position in the direction closer to the first plate, the pressing member pushes the seal to slide in the direction closer to the second plate and abuts against the second plate.

[0017] By adopting the above technical solution, during the construction of the double-wall body, after both double-wall bodies are hoisted, the control extrusion component slides and pushes the sealing component to slide until it abuts against the second plate. At this time, the sealing component can seal the gap between the first plate and the second plate, thereby improving the sealing effect of the protective component at the corner connection of the two double-wall bodies.

[0018] Optionally, the protective component further includes a trigger, which is disposed on the side of the fixed seat near the base. When the base slides towards the fixed seat to its limit position, the trigger penetrates the base and pushes the pressing member to slide towards the first plate to its limit position.

[0019] By adopting the above technical solution, the base is controlled to slide towards the fixed seat. During the process of changing the installation position on the double-wall body, the trigger will automatically push the squeezing component to slide. The sliding of the squeezing component will then push the sealing component to slide between the first plate and the second plate to form a seal. This allows the protective component to automatically complete the operation steps to improve the sealing effect after adjustment, thereby further reducing the construction difficulty.

[0020] Optionally, the protective assembly further includes a plurality of first elastic elements and a plurality of second elastic elements, wherein the plurality of first elastic elements are disposed inside the first plate and the first elastic elements drive the sealing element to slide away from the second plate; and the plurality of second elastic elements are disposed inside the base and the second elastic elements drive the pressing element to slide away from the first plate.

[0021] By adopting the above technical solution, after the base slides away from the fixed seat, a number of first elastic elements drive the sealing element to slide and reset, and a number of second elastic elements drive the squeezing element to slide and reset. This enables the protective component to quickly recover, reducing the probability of problems such as the first plate and the second plate being unable to rotate relative to each other due to the sealing element, thereby further reducing the difficulty of operation.

[0022] Optionally, the first plate has a guide groove at one end near the second plate to guide the direction of the seal's protrusion, and the second plate has an insertion groove at one end near the first plate for the end of the seal to be inserted; when the first plate is perpendicular to the second plate, when the seal slides to its limit position in the direction near the second plate, the seal passes through the guide groove and is inserted into the insertion groove.

[0023] By adopting the above technical solution, the guide groove guides the seal to slide and engage with the insertion groove, thereby improving the stability and reliability of the engagement between the seal and the insertion groove. At the same time, the seal is engaged with the insertion groove at its end between the first plate and the second plate, which further enhances the sealing effect of the seal.

[0024] Optionally, it also includes a number of embedded parts, which are respectively disposed at one end of the outer sheet and the inner sheet near the corner connection of the double-layer wall body; the protective component also includes a number of positioning bolts, which correspond one-to-one with the number of embedded parts, and the positioning seat is provided with a number of positioning holes for the positioning bolts to pass through, and the positioning bolts are threadedly engaged with the embedded parts.

[0025] By adopting the above technical solution, the positioning seat is fixedly connected to the double-wall body through the threaded engagement of the positioning bolt and the embedded part, which can further improve the positional stability between the positioning seat and the double-wall body after positioning; in addition, the threaded engagement of the positioning bolt and the embedded part can also have a correction effect on the double-wall body, thereby further improving the final construction effect of the double-wall body.

[0026] Optionally, both the outer and inner pages have abutting surfaces at the corners of the double-wall body. When the abutting surfaces of the two outer and inner pages are respectively attached to each other, the two double-wall bodies are perpendicular to each other.

[0027] By adopting the above technical solution, after the two double-wall main bodies are hoisted, the corresponding abutting surfaces fit together and abut against each other. Using the abutting surfaces as an aid can further facilitate the hoisting of the double-wall main bodies, and at the same time further reduce the probability of concrete seeping out from the gap between the two double-wall main bodies.

[0028] On the other hand, this application also provides a construction method, which adopts the following technical solution:

[0029] A construction method, applied to the aforementioned assembled composite building double-skin exterior wall structure, comprises the following steps:

[0030] S1. After the two double-layer wall bodies at the corner connection are processed, the protective components are installed on the two double-layer wall bodies respectively, so that the first plate and the second plate together protect the outer plate and the inner plate near the corner connection of the double-layer wall body.

[0031] S2, the two double-skin wall main bodies at the transportation corner connection;

[0032] S3. After the main body of the double-layer wall is hoisted, adjust the corresponding protective components to release the protective effect of the protective components on the outer leaf plate and the inner leaf plate near the corner connection of the main body of the double-layer wall.

[0033] S4. Using the second plate on one of the double-wall bodies that has been hoisted as an aid, hoist another double-wall body so that the ends of the two double-wall bodies abut against each other;

[0034] S5. Concrete is poured into the cavity of the double-wall body, and the two protective components respectively play a sealing role on the inner and outer sides of the corner connection of the two double-wall bodies.

[0035] In summary, this application includes at least one of the following beneficial effects:

[0036] 1. The protective components can better protect the outer panels of the double-skin wall body during transportation, and at the same time, they can comprehensively improve the sealing of the corner joints, thereby further facilitating subsequent concrete pouring construction;

[0037] 2. It can reduce the difficulty of construction, thereby making it easier for construction workers to construct the double-skin wall structure;

[0038] 3. The protective components have higher sealing performance, providing a better sealing effect at the corner joints of the two double-layer wall panels;

[0039] 4. During the construction of the double-wall structure, the protective components can assist in the hoisting of the double-wall structure, improve the positional accuracy of the double-wall structure after hoisting, and also play a role in correcting the position of the double-wall structure.

[0046] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0047] Example 1:

[0048] Reference Figure 1 This application discloses an assembly-type double-skin exterior wall structure for use at building corners after construction. In this embodiment, the building corner is preferably a right-angle structure, which is used as an example to introduce the assembly-type double-skin exterior wall structure and provide accompanying drawings. In other embodiments, simple structural and dimensional adjustments to the assembly-type double-skin exterior wall structure can also be made to form building corners with different angles.

[0049] Reference Figure 1 and Figure 2 The assembled composite building double-skin exterior wall structure includes a double-skin wall body 1 and a protective component 2. The double-skin wall body 1 is the main construction body and is used to form the wall of the building after construction. The protective component 2 plays a protective role during the transportation of the double-skin wall body 1 and plays a sealing role at the corner connection between it and another double-skin wall body 1 during the construction of the double-skin wall, so as to facilitate the subsequent concrete pouring construction.

[0050] Reference Figure 1 and Figure 3 In this embodiment, the preferred corner structure of the building is constructed by splicing two assembled building double-skin exterior wall structures. In the two assembled building double-skin exterior wall structures, the main body 1 of the double-skin wall is similar, and the protective components 2 are the same.

[0051] Back Figure 1 and Figure 2 The main body 1 of the double-skin wall is a rectangular parallelepiped structure, including an outer sheet 11, an inner sheet 12, and a steel reinforcement structure 13. The outer sheet 11 and the inner sheet 12 are parallel to each other, and the steel reinforcement structure 13 is located between the outer sheet 11 and the inner sheet 12. Both ends of the steel reinforcement structure 13 are fixedly connected to the outer sheet 11 and the inner sheet 12 respectively by embedding. In this embodiment, it is preferable that the outer sheet 11 and the inner sheet 12 are both rectangular plate structures, and both the outer sheet 11 and the inner sheet 12 are constructed with their width sides vertical.

[0052] One end face of the outer sheet 11 is perpendicular to its own length direction, and this end face of the outer sheet 11 is flush with one end face of the inner sheet 12 in the length direction. The length dimension of the outer sheet 11 is greater than that of the inner sheet 12, so one end of the outer sheet 11 in the length direction will be exposed relative to the inner sheet 12. This is the corner connection of the double-skin wall body 1.

[0053] After the two assembled building double-skin exterior wall structures are hoisted, before the pouring construction, the two double-skin wall main bodies 1 must be in a mutually perpendicular state, and the ends of the two outer leaf plates 11 near the corner connection should abut against each other, and the ends of the two inner leaf plates 12 near the corner connection should also abut against each other. At this time, the two outer leaf plates 11 are located on the outside of the two inner leaf plates 12, thereby reducing the probability of concrete leakage from the corner connection of the two double-skin wall main bodies 1 during the pouring construction.

[0054] Back Figure 1 and Figure 3 Furthermore, preferably, both the outer sheet 11 and the inner sheet 12 have abutting surfaces 14 near the corner connection, and preferably the abutting surfaces 14 are inclined surfaces. When the two double-layer walls are vertically spliced, the abutting surfaces 14 of the two outer sheet 11 are fitted together, and the abutting surfaces 14 of the two inner sheet 12 are also fitted together. This facilitates construction and further reduces the probability of concrete leakage from the corner connection of the two double-layer wall bodies 1 during pouring.

[0055] Back Figure 1 and Figure 2 The protective component 2 corresponds one-to-one with the double-skin wall body 1, and the protective component 2 and the double-skin wall body 1 are detachably connected. The protective component 2 includes a first plate 21, a second plate 22, and a base 23. Preferably, the first plate 21, the second plate 22, and the base 23 are all cuboid structures, and after the protective component 2 is installed on the double-skin wall body 1, the length sides of the first plate 21, the second plate 22, and the base 23 are all parallel to the width side of the double-skin wall body 1.

[0056] The two ends of the first plate 21 in the width direction are respectively rotatably connected to one end of the second plate 22 in the width direction and one end of the base 23 in the width direction. The rotation axis of the second plate 22 relative to the first plate 21 and the rotation axis of the base 23 relative to the first plate 21 are parallel to each other and both are parallel to the length side of the first plate 21.

[0057] The base 23 is installed on the side of the outer page plate 11 facing away from the inner page plate 12 near the corner connection, and on the side of the inner page plate 12 facing away from the outer page plate 11 near the corner connection. In this embodiment, preferably, the two bases 23 are installed on the corresponding outer page plate 11 and inner page plate 12 on the two double-skin wall bodies 1.

[0058] Taking the double-skin wall body 1 with the base 23 installed on the outer page plate 11 as an example, when the base 23 is installed on the outer page plate 11 in the installation area near the corner connection, the first plate 21 is controlled to rotate relative to the base 23 towards the inner page plate 12 until the first plate 21 is perpendicular to the base station. Then, the second plate 22 is controlled to rotate relative to the first plate 21 towards the inner page plate 12 until the second plate 22 is perpendicular to the first plate 21. At this time, the first plate 21 is perpendicular to the double-skin wall body 1, and the base 23 and the second plate 22 are both parallel to the double-skin wall body 1. At this time, the protective component 2 can enclose the end of the double-skin wall body 1 near the corner connection to form protection, thereby achieving the protective effect.

[0059] When the base 23 is installed on the outer page plate 11 at a position away from the corner connection in its installation area, the first plate 21 is controlled to rotate relative to the base 23 away from the inner page plate 12 until the first plate 21 is parallel to the base station. Then, the second plate 22 is controlled to rotate relative to the first plate 21 towards the inner page plate 12 until the second plate 22 is perpendicular to the first plate 21. At this time, both the base 23 and the first plate 21 are parallel to the double-wall body 1, and the second plate 22 is perpendicular to the double-wall body 1. After the two double-layer wall body 1 are vertically spliced, the outer side of the outer panel 11 of the other double-layer wall body 1 will be attached to and abut against the second panel 22, and the protective structure will be located on the outside of the two double-layer wall body 1 near the corner connection; thus, the protective structure has the effect of guiding the two double-layer wall body 1 to be accurately vertically spliced, and after the two double-layer wall body 1 are vertically spliced, it has the effect of improving the sealing of the corner connection near the outside, thereby further reducing the probability of concrete leakage from the outside of the corner connection of the two double-layer wall body 1 during the pouring construction.

[0060] Back Figure 1 and Figure 3 The structure of the double-skin wall body 1 with the base 23 installed on the inner page plate 12 is similar to that of the double-skin wall body 1 with the base 23 installed on the outer page plate 11. It can be deduced from the structure of the double-skin wall body 1 with the base 23 installed on the outer page plate 11. Therefore, the structure of the double-skin wall body 1 with the base 23 installed on the inner page plate 12 will not be described in detail here.

[0061] Unlike the double-skin wall body 1 where the base 23 is mounted on the outer page plate 11, for the double-skin wall body 1 where the base 23 is mounted on the inner page plate 12, when the base 23 is mounted on the inner page plate 12 at a position away from the corner connection in its installation area, the first plate 21 is controlled to rotate relative to the base 23 in a direction away from the outer page plate 11 until the first plate 21 is parallel to the base station. Then, the second plate 22 is controlled to rotate relative to the first plate 21 in a direction away from the outer page plate 11 until the second plate 22 is perpendicular to the first plate 21. At this time, both the base 23 and the first plate 21 are parallel to the double-skin wall body 1. The second plate 22 is perpendicular to the double-wall body 1. After the two double-wall bodies 1 are vertically spliced, the inner side of the inner plate 12 of the other double-wall body 1 will fit against the second plate 22, and the protective structure will be located on the inner side of the two double-wall bodies 1 near the corner connection. Thus, the protective structure also has the effect of guiding the two double-wall bodies 1 to be accurately spliced ​​vertically, and after the two double-wall bodies 1 are vertically spliced, it has the effect of improving the sealing of the inner part of the corner connection, thereby further reducing the probability of concrete leakage from the inner side of the corner connection of the two double-wall bodies 1 during the pouring construction.

[0062] Reference Figure 1 and Figure 4 Furthermore, the protective component 2 also includes a positioning seat 24, which is also a rectangular plate structure. One end of the positioning seat 24 in the width direction is rotatably connected to the end of the second plate 22 away from the first plate 21, and the rotation axis of the positioning seat 24 relative to the second plate 22 is parallel to the rotation axis of the second plate 22 relative to the first plate 21. On the double-layer wall body 1, the positioning seat 24 can be fixedly installed at the corner connection position on the side of the outer plate 11 away from the inner plate 12 and at the corner connection position on the side of the inner plate 12 away from the outer plate 11.

[0063] When the protective component 2 provides protection for the double-wall body 1, the positioning seat 24 is fixedly connected to the outer leaf plate 11 or inner leaf plate 12 on the same double-wall body 1. At this time, the second plate 22 is fixedly connected to the double-wall body 1 through the positioning seat 24, thereby improving the relative positional stability between the protective component 2 and the double-wall body 1. When the protective component 2 improves the sealing performance of the double-wall body 1, the positioning seat 24 is fixedly connected to the outer leaf plate 11 or inner leaf plate 12 on another double-wall body 1. At this time, the second plate 22 is fixedly connected to the other double-wall body 1 through the positioning seat 24, thereby improving the relative positional stability between the two double-wall bodies and further enhancing the sealing performance of the protective component 2.

[0064] Reference Figure 2 and Figure 4Furthermore, the assembled composite building double-skin exterior wall structure also includes several embedded parts 4, and the protective component 2 also includes several positioning bolts 3. The embedded parts 4 are fixedly installed on the double-skin wall body 1. For the double-skin wall body 1 with the base 23 installed on the outer leaf plate 11, several embedded parts 4 are embedded on its inner leaf plate 12 near the corner connection; for the double-skin wall body 1 with the base 23 installed on the inner leaf plate 12, several embedded parts 4 are embedded on its outer leaf plate 11 near the corner connection; and the several embedded parts 4 are evenly distributed along the width direction of the double-skin wall body 1.

[0065] The positioning seat 24 has several positioning holes 241 at its end away from the second plate 22, through which positioning bolts 3 pass. Each positioning hole 241 corresponds to a positioning bolt 3. After the fixing seat 25 abuts against the other double-wall body 1 and determines its position, the positioning holes 241 correspond one-to-one with a number of embedded parts 4 on the other double-wall body 1. The positioning bolts 3 pass through the positioning holes 241 and engage with the embedded parts 4 via threads. When there is a certain positional error after the two double-wall bodies 1 are vertically spliced, the threaded engagement of the positioning bolts 3 and the embedded parts 4 can correct the misalignment of the double-wall body 1 relative to the other double-wall body 1.

[0066] Reference Figure 1 and Figure 5 Furthermore, the protective component 2 also includes several positioning elements 5. In this embodiment, the preferred rotational connection positions between the base 23 and the first plate 21, the rotational connection positions between the first plate 21 and the second plate 22, and the rotational connection positions between the second plate 22 and the positioning seat 24 are all equipped with positioning elements 5 to restrict the rotation of the corresponding two parts, so that the relative positions of the two parts are fixed after the relative rotation is adjusted.

[0067] In this embodiment, the positioning element 5 and its function are introduced using the rotational connection position between the first plate 21 and the second plate 22 as an example. The application of the positioning element 5 in the rotational connection position between the base 23 and the first plate 21 and the rotational connection position between the second plate 22 and the positioning seat 24 is similar.

[0068] The second plate 22 has a sliding hole 101 at one end near the first plate 21 along its own length for the positioning member 5 to slide and engage. The positioning member 5 passes through the sliding hole 101, and the sliding direction of the positioning member 5 is parallel to the length direction of the second plate 22. The first plate 21 has a locking groove at one end near the second plate 22 along its own length for the positioning member 5 to be inserted and engaged. After the positioning member 5 slides, it can be inserted and engaged with the locking groove. When the positioning member 5 is inserted and engaged with the locking groove, the rotation of the second plate 22 relative to the first plate 21 is restricted.

[0069] Furthermore, preferably, the positioning member 5 can only slide into the locking groove and engage with it when the second plate 22 is rotated relative to the first plate 21 to a specific state. In this embodiment, the cross-section of the part where the positioning member 5 engages with the locking groove is preferably square, and the positioning member 5 can only slide into the locking groove and engage with it when the second plate 22 is rotated relative to the first plate 21 to a state where they are parallel or perpendicular to each other.

[0070] Furthermore, preferably, each positioning member 5 is equipped with a third elastic member 6. The two ends of the third elastic member 6 are fixedly connected to the positioning member 5 and the second plate 22, respectively. The third elastic member 6 drives the positioning member 5 to slide towards the locking groove. In this embodiment, the third elastic member 6 is preferably a tension spring. When the positioning member 5 is aligned with the locking groove and its shape is suitable, the third elastic member 6 will drive the positioning member 5 to slide until it is engaged with the locking groove and remains in place.

[0071] Furthermore, the base 23 is preferably slidably connected to the double-wall body 1, and the protective component 2 preferably also includes a fixing seat 25, adjusting bolts 251 and several guide members 252. The fixing seat 25 is preferably a rectangular plate structure. The fixing seat 25 is fixedly installed on the double-wall body 1 and is located on the side of the base 23 away from the first plate 21. That is, the fixing seat 25 and the base station of the same protective component 2 are installed on the same outer plate 11 or inner plate 12.

[0072] An adjusting bolt 251 passes through a fixing seat 25 along the length direction parallel to the main body 1 of the double-wall structure and is threaded into the fixing seat 25. The tail of the adjusting bolt 251 is rotatably connected to the base 23, and the rotation axis of the adjusting bolt 251 relative to the base 23 coincides with its own axis. One end of the guide member 252 is fixedly connected to the base 23, and the guide member 252 passes through and engages with the fixing seat 25. The guide member 252 and the adjusting bolt 251 are parallel to each other. In this embodiment, the protective component 2 preferably includes one guide member 252, and the guide member 252 and the adjusting bolt 251 are respectively installed at both ends of the fixing seat 25 along its length direction.

[0073] Rotating the adjusting bolt 251 causes the base 23 to slide relative to the fixed seat 25 along the guide 252, i.e., controlling the base 23 to slide on the double-skin wall in a direction parallel to the length of the double-skin wall body 1. This facilitates the construction personnel in changing the position of the base 23 on the double-skin wall body 1. When the base 23 slides away from the fixed seat 25 to its limit position, it will be located on the double-skin wall body 1 near the corner connection within its installation area. When the base 23 slides towards the fixed seat 25 to its limit position (preferably, the base 23 abuts against the fixed seat 25), it will be located on the double-skin wall body 1 away from the corner connection within its installation area. When there is a certain positional error after the two double-skin wall bodies 1 are vertically spliced, controlling the base 23 to slide and cause the second plate 22 to abut against the other double-skin wall body 1 can also correct the deviation.

[0074] Reference Figure 1 and Figure 4 Furthermore, the protective component 2 also includes an extrusion member 26 and a sealing member 27. In this embodiment, it is preferred that both the extrusion member 26 and the sealing member 27 are sheet-like structures. The extrusion member 26 is slidably installed inside the base 23, and the sliding direction of the extrusion member 26 is parallel to the width direction of the base 23. During the sliding process, both ends of the extrusion member 26 can extend out of the base 23. The sealing member 27 is slidably installed inside the first plate 21, and the sliding direction of the sealing member 27 is parallel to the width direction of the first plate 21. During the sliding process, both ends of the sealing member 27 can also extend out of the first plate 21.

[0075] The extrusion member 26 is restricted during its sliding relative to the base 23. When the extrusion member 26 slides away from the first plate 21 to its limit position, the extrusion member 26 is completely inside the base 23. When the extrusion member 26 slides towards the first plate 21 to its limit position, one end of the extrusion member 26 extends out of the base 23 and is located on the side of the base 23 closer to the first plate 21, while the other end of the extrusion member 26 retracts into the base 23.

[0076] The sealing element 27 is also restricted during its sliding relative to the first plate 21. When the sealing element 27 slides to its limit position in the direction closer to the base 23, the sealing element 27 is completely inside the first plate 21. When the sealing element 27 slides to its limit position in the direction away from the base 23, one end of the sealing element 27 extends out of the first plate 21 and abuts against the second plate 22, while the other end of the sealing element 27 retracts into the interior of the first plate 21.

[0077] When the protective component 2 improves the sealing performance of the double-layer wall body 1, the control member 26 slides towards the first plate 21 to its limit position. The control member 26 pushes the sealing member 27 to slide so that its end abuts against the second plate 22. At this time, the end of the sealing member 27 near the second plate 22 can seal the gap between the first plate 21 and the second plate 22, thereby further improving the sealing performance of the protective component. In this embodiment, the sealing member 27 is preferably made of rubber.

[0078] Furthermore, the protective component 2 also includes a trigger 28. In this embodiment, the trigger 28 is preferably also a sheet-like structure. The trigger 28 is fixedly installed on the side of the fixing base 25 near the base 23. As the base 23 slides towards the fixing base 25 to its limit position, the trigger 28 can push the pressing member 26 towards the first plate 21, thereby causing the pressing member 26 to push the sealing member 27 towards the second plate 22 until it abuts against the second plate 22.

[0079] Furthermore, the preferred sealing element 27 is flexible, the first plate 21 has a guide groove 211 for guiding the extension direction of the sealing element 27 at one end near the second plate 22, and the second plate 22 has an insertion groove 221 for inserting the end of the sealing element 27 at one end near the first plate 21.

[0080] When the protective component 2 improves the sealing performance of the double-wall body 1, the second plate 22 is perpendicular to the first plate 21. When the sealing element 27 is pushed by the extrusion member 26, the end of the sealing element 27 near the second plate 22 will change its extension direction along the guide groove 211, and finally the end of the sealing element 27 can be inserted into the insertion groove 221, thereby improving the sealing effect of the sealing element 27.

[0081] Furthermore, the protective component 2 also includes a plurality of first elastic elements 103 and a plurality of second elastic elements 104. The plurality of first elastic elements 103 are all installed inside the first plate 21, with both ends of each first elastic element 103 fixedly connected to the seal 27 and the first plate 21, respectively. The first elastic elements 103 can drive the seal 27 to slide towards the base 23 to its limit position and maintain it thereafter. The plurality of second elastic elements 104 are all installed inside the base 23, with both ends of each second elastic element 104 fixedly connected to the compression member 26 and the base 23, respectively. The second elastic elements 104 can drive the compression member 26 to slide away from the first plate 21 to its limit position and maintain it thereafter. In this embodiment, preferably, both the first elastic elements 103 and the second elastic elements 104 are compression springs.

[0082] After the base 23 slides away from the fixed base 25, a number of second elastic elements 104 will drive the pressing element 26 to slide back to its original position relative to the base 23, and at the same time, a number of first elastic elements 103 will also drive the sealing element 27 to slide back to its original position relative to the first plate 21.

[0083] The implementation principle of an assembled composite building double-skin exterior wall structure in this application is as follows:

[0084] Before transportation, the protective component 2 is installed on the double-wall body 1. The protective component 2 is then adjusted so that the first plate 21 and the second plate 22 enclose the end of the double-wall body 1 near the corner connection to provide protection. Then the transportation and hoisting operation is carried out, thereby reducing the probability of the double-wall body 1 being damaged by bumps during the transportation and hoisting operation.

[0085] During the hoisting operation, the protective component 2 is adjusted so that it releases its protective function on the double-wall body 1 and is placed in a position that improves the sealing performance. At this time, the second plate 22 has an auxiliary effect on the hoisting process of the other double-wall body 1, which facilitates the accurate hoisting position of the other double-wall body 1 and can also correct the deviation of the other double-wall body 1.

[0086] During the pouring process, the two protective components 2 act as seals on the inner and outer sides of the corner connection between the two double-skin wall bodies 1, which can further reduce the probability of concrete leakage and thus improve the pouring effect.

[0087] Example 2:

[0088] This application discloses a construction method applied to a double-skin exterior wall structure of an assembled building as described in Example 1. The specific steps are as follows:

[0089] S1. After the two double-layer wall body 1 at the corner connection is processed, the protective components 2 are installed on the two double-layer wall body 1 respectively, so that the first plate 21 and the second plate 22 jointly protect the outer page plate 11 and the inner page plate 12 near the corner connection of the double-layer wall body 1.

[0090] After the double-skin wall body 1 is processed, the protective component 2 is installed on the double-skin wall body 1, so that the fixing seat 25 is fixedly installed on the double-skin wall body 1. The base 23 is controlled to slide away from the fixing seat 25 to the limit position, and the first plate 21 and the second plate 22 are controlled to rotate so that they surround the end of the double-skin wall body 1 near the corner connection. Then, the positioning seat 24 is fixed to the double-skin wall body 1 by several positioning bolts 3 and several embedded parts 4 threadedly engaging.

[0091] S2, the main body of the two double-layered wall at the corner connection of the transportation.

[0092] The two double-skin wall bodies 1, each equipped with protective components 2, were transported to the construction site and hoisted into place.

[0093] S3. After the double-layer wall body 1 is hoisted, adjust the corresponding protective component 2 to release the protective function of the protective component 2 at the end of the outer page plate 11 and the inner page plate 12 near the corner connection of the double-layer wall body 1.

[0094] First, hoist a double-wall body 1 to the required position, then adjust the protective components 2 on it, release the fixing between the positioning seat 24 and the double-wall body 1, control the rotation of the first plate 21 and the second plate 22, and then control the base 23 to slide towards the fixed seat 25 to the limit position, so that the second plate 22 plays an auxiliary role in the hoisting operation of the other double-wall body 1.

[0095] S4. Using the second plate 22 on the completed double-wall body 1 as an aid, hoist another double-wall body 1 so that the ends of the two double-wall bodies 1 abut against each other.

[0096] The same adjustment operation is performed on the protective component 2 on the other double-wall body 1 so that its second plate 22 can also play an auxiliary role in the hoisting operation of the double-wall body 1 on which it is located. Then, the hoisting operation is carried out while the double-wall body 1 and the second plate 22 are in close contact and abutting each other. After the initial hoisting of the other double-wall body 1 is completed, the second plate 22 can be driven to correct the other double-wall body 1 by controlling the sliding of the base 23. In addition, the positioning seat 24 is fixed to the other double-wall body 1 by several positioning bolts 3 and several embedded parts 4 threadedly engaged. During this process, the other double-wall body 1 can also be corrected.

[0097] S5. Pour concrete into the cavity of the double-wall body 1, and the two protective components 2 respectively seal the inner and outer sides of the corner connection of the two double-wall bodies 1.

[0098] When concrete is poured into the air of the double-wall body 1, the sealing element 27, which is inserted and matched with the insertion groove 221, can improve the sealing of both sides of the corner connection of the two double-wall bodies 1, prevent concrete from seeping out, facilitate the pouring construction, and improve the pouring effect.

[0099] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
