Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building thermal insulation, in particular to an integrated wall panel with a thermal insulation structure, and further relates to a wall structure. Background Art
[0002] There are generally two existing ways of building walls. One is to directly install the prefabricated integrated wall panel with a thermal insulation structure from the factory at the construction site. This way is for assembled wall construction. The integrated wall panel with a thermal insulation structure usually includes a concrete layer and a thermal insulation layer, and the concrete layer and the thermal insulation layer are cast and bonded together and formed in the factory, and directly transported to the construction site for assembly during construction; the other is the traditional on-site cast-in-place wall method. First, tie the steel bar cage, support the inner and outer templates, pour concrete into the casting cavity, and the concrete solidifies to form the base wall. There is a thermal insulation board outside the base wall. The thermal insulation board can be placed during the pouring of concrete and cast in place with the base wall, or can be laid after the base wall is formed. In order to make the outside of the wall beautiful and play a certain protective function for the thermal insulation layer, a dry-hanging curtain wall is usually installed outside the thermal insulation layer.
[0003] Currently, when installing a dry-hanging curtain wall, the common method is: after installing the integrated thermal insulation board or on the wall cast in place on site, make a hole in the outer thermal insulation layer, then drive in an expansion bolt, drive one end of the expansion bolt into the concrete layer, and the other end of the expansion bolt is exposed outside, connect and fix the steel plate, weld the connecting keel on the fixed steel plate, and connect the connecting keel with the main keel to form the main keel frame, so as to realize the installation of the dry-hanging curtain wall. However, this method has the following problems: at the construction site, it is necessary to make holes in the thermal insulation layer to drive in expansion bolts to fix the steel plate, which is easy to damage the thermal insulation layer, and due to a large number of holes, the integrity of the thermal insulation is damaged and later thermal insulation repair is involved. And due to the large number of fixed steel plates installed, it is difficult to ensure the verticality and horizontality between the fixed steel plates, resulting in it being difficult to ensure the verticality and squareness of the connection between the keel and the wall. Using a level or pulling a wire will greatly reduce the construction efficiency; moreover, the installation of expansion bolts and fixed steel plates causes a heavy workload for workers. While the efficiency is low, a large amount of dust will be generated due to drilling, which will also affect the environment, and there will also be problems of non-standard construction. Summary of the Utility Model
[0004] The purpose of the utility model is to propose and design a connector, an integrated wall panel with a thermal insulation structure and a wall structure for the problems of low efficiency, non-standard construction and easy damage to the thermal insulation layer when driving connectors at the construction site when installing a keel on the existing integrated wall panel with a thermal insulation structure.
[0005] The technical solution adopted by the present utility model to solve the above technical problems is as follows: a connecting piece, a part of the connecting piece is used for installation in a concrete layer, another part of the connecting piece is used for connection to a thermal insulation layer, an inner and outer moving groove is arranged on the connecting piece, an opening is arranged at the outer end of the connecting piece, an inner and outer moving member is installed in the inner and outer moving groove, and the inner and outer moving member is used for connecting the keel of a dry hanging curtain wall. The function of the connecting piece is described in the next paragraph.
[0006] Furthermore, based on the above-mentioned connecting piece, an integrated wall panel with a thermal insulation structure is provided, which includes a concrete layer and a thermal insulation layer. The thermal insulation layer is located outside the concrete layer; it also includes a connecting piece, a part of the connecting piece is located in the concrete layer, and the other part of the connecting piece is located in the thermal insulation layer. An internal and external moving groove is provided on the connecting piece, and an opening is provided at the outer end of the connecting piece. A hole is provided at the position corresponding to the opening on the outer board surface of the thermal insulation layer, and the connecting piece does not protrude from the outer board surface of the thermal insulation layer. A part of the connecting piece is located in the concrete layer. On the one hand, it ensures the installation depth of the connecting piece, and on the other hand, it can ensure the firmness of the fixing of the connecting piece and improve the load-bearing capacity. Because the material of the thermal insulation layer has a poor hardness and is only set in the thermal insulation layer, it is not firm and cannot meet the load-bearing requirements; an internal and external moving groove is provided on the connecting piece. After installing internal and external moving parts on the connecting piece, the internal and external moving groove provides a moving space for the internal and external moving parts in the internal and external directions, and the internal and external moving parts can move in and out along the internal and external moving groove. The opening on the connecting piece and the hole on the thermal insulation layer (this hole can be flush with the opening) can allow the internal and external moving parts to pass through. The internal and external moving parts pass through the opening hole on the connecting piece and extend out of the thermal insulation layer to connect the keel of the dry hanging curtain wall. Among them, one installation method of the internal and external moving parts is to install before the concrete layer is formed. When the internal and external moving parts are not in use, they are located in the internal and external moving groove and do not protrude from the outer board surface of the thermal insulation layer either. Another installation method is to install after the integrated wall panel with the thermal insulation structure is formed or during the wall construction. The above two installation methods can ensure that the outer board surface of the thermal insulation layer is flat when the concrete layer is formed, and further ensure that the outer formwork fits the outer board surface of the thermal insulation layer. Further speaking, when supporting the outer formwork during the formation of the integrated wall panel with the thermal insulation structure, the outer formwork needs to fit the outer board surface of the thermal insulation layer. Concrete is poured on one side of the inner board surface of the thermal insulation board. If the connecting piece or the internal and external moving parts protrude from the outer board surface of the thermal insulation layer, they will top against the outer formwork, and a gap will be generated between the outer board surface of the thermal insulation layer and the outer formwork. The outer formwork cannot fit the outer board surface of the thermal insulation layer, and when pouring concrete into the pouring cavity, it will impact the thermal insulation layer, causing deformation and movement of the thermal insulation layer, and the pouring thickness of the concrete layer cannot be well controlled. However, this solution can well solve this problem, and because the connecting piece does not protrude from the thermal insulation layer, it avoids the problem of damaging adjacent wall panels during storage and transportation and the large spacing between wall panels, which is convenient for transportation and stacking. Therefore, through the integrated wall panel with the thermal insulation structure provided by this solution, it can be directly transported to the construction site for installation after being formed in the factory. If the internal and external moving parts have been prefabricated on the connecting piece, the internal and external moving parts can be directly pulled out or screwed out during use and connected to the keel of the dry hanging curtain wall. If the internal and external moving parts are not prefabricated, the internal and external moving parts can be inserted into the connecting piece from the outer board surface of the protective layer at the construction site. This saves the work of punching and driving expansion bolts on site, greatly improves the construction efficiency, and because the connecting piece is prefabricated in the factory, it can accurately ensure the position of the connecting piece and avoid construction non-standardization.In this solution, the concrete layer is generally about 200 mm, and the thermal insulation layer is an A-level fireproof thermal insulation board. Since this solution meets the fire protection requirements, there is no need to set up a protective layer outside the thermal insulation layer.
[0007] An integrated wall panel with a thermal insulation structure, comprising a concrete layer, a thermal insulation layer and a protective layer (generally called a sandwich precast wall panel in the art). The thermal insulation layer is located outside the concrete layer, and the protective layer is located outside the thermal insulation layer. It also includes a connecting piece, a part of the connecting piece is located in the concrete layer, and the other part of the connecting piece is located in the thermal insulation layer and the protective layer. An internal and external moving groove is provided on the connecting piece, an opening is provided at the outer end of the connecting piece, a hole is provided at the position corresponding to the opening on the outer plate surface of the protective layer, and the connecting piece does not protrude from the outer plate surface of the protective layer. A part of the connecting piece is located in the concrete layer, which on the one hand ensures the installation depth of the connecting piece, and on the other hand can ensure the firm fixation of the connecting piece and improve the load-bearing capacity. Since the material of the thermal insulation layer is of poor hardness and the protective layer is thin, only setting it in the thermal insulation layer and the protective layer is not firm and cannot meet the load-bearing requirements. An internal and external moving groove is provided on the connecting piece. After an internal and external moving part is installed on the connecting piece, the internal and external moving groove provides a moving space for the internal and external moving part in the internal and external directions, and the internal and external moving part can move in and out along the internal and external moving groove. The opening on the connecting piece and the hole on the protective layer (this hole can be flush with the opening) can enable the internal and external moving part to pass through. The internal and external moving part passes through the opening on the connecting piece and extends out of the protective layer for connecting the keel of the dry hanging curtain wall. Among them, one installation method of the internal and external moving part is to install it before the concrete layer is poured and formed. When the internal and external moving part is not in use, it is located in the internal and external moving groove and does not protrude from the outer plate surface of the protective layer either. Another installation method is to install it after the integrated wall panel with the thermal insulation structure is formed or during the wall construction. The above two installation methods can ensure that the outer plate surface of the protective layer is flat when the concrete layer is formed, thereby ensuring the fitting of the outer formwork to the outer plate surface of the protective layer. Further, when the integrated wall panel with the thermal insulation structure is formed, the outer formwork is supported, the concrete is laid to form the protective layer, then the thermal insulation layer is placed on the inner plate surface of the protective layer, and then the concrete is poured on one side of the inner plate surface of the thermal insulation layer. This process requires the outer formwork to fit the outer plate surface of the protective layer. If the connecting piece or the internal and external moving part protrudes from the outer plate surface of the protective layer, it will top on the outer formwork, and a gap will be generated between the outer plate surface of the protective layer and the outer formwork. The outer formwork cannot fit to the outer plate surface of the protective layer. When pouring concrete into the pouring cavity, it will impact the thermal insulation layer and the protective layer, causing deformation and movement of the thermal insulation layer and the protective layer, and the pouring thickness of the concrete layer cannot be well controlled. However, this solution can well solve this problem, and because the connecting piece does not protrude from the protective layer, it avoids the problem of damaging adjacent wall panels during storage and transportation and the large distance between wall panels, and is convenient for transportation and stacking.Therefore, with the integrated thermal insulation wall panel provided by this solution, it can be directly transported to the construction site for installation after being formed in the factory. If the internal and external moving parts have been prefabricated on the connecting piece, the internal and external moving parts can be directly pulled out or screwed out during use and connected to the keel of the dry-hanging curtain wall. If the internal and external moving parts are not prefabricated, the internal and external moving parts can be inserted into the connecting piece on-site. The internal and external moving parts are inserted from the outer board surface of the protective layer into the opening of the connecting piece to be connected to the connecting piece, eliminating the work of drilling expansion bolts on-site, greatly improving the construction efficiency, and because the connecting pieces are prefabricated in the factory, the positions of the connecting pieces can be well guaranteed, avoiding construction non-standardization. In this solution, a Class B fireproof thermal insulation board can be used for the thermal insulation layer. In order to meet the fireproof requirements, a protective layer is provided on the outside of the thermal insulation layer to form a sandwich thermal insulation wall panel.
[0008] Furthermore, the connecting piece includes a connecting steel plate and a nested block. The nested block is used to install the internal and external moving parts. The nested block is fixedly connected to the connecting steel plate. The cross-sectional area of the connecting steel plate is larger than that of the nested block. The connecting steel plate is located inside the thermal insulation layer and in the concrete layer, and the nested block is located in the thermal insulation layer (either partially or entirely). During installation, the connecting steel plate can be attached to the thermal insulation layer to limit the nested block, and due to its large cross-sectional area, when poured into the concrete layer, it has good tensile and pull-out resistance, improving the load-bearing capacity of the connecting piece. Here, the nested block can be cylindrical, plate-shaped, or of other common shapes.
[0009] Furthermore, the internal and external moving grooves are located in the nested block (here, the cylindrical cavity of the nested block can be regarded as the internal and external moving grooves). The nested block is horizontally arranged and is perpendicular to the outer board surface of the thermal insulation layer as a whole. The opening is provided at one end of the nested block away from the connecting steel plate (i.e., the outer end of the nested block), and the opening communicates with the internal and external moving grooves. This can make the internal and external moving parts located in the nested block, avoiding interference and facilitating the movement of the internal and external moving parts. If the internal and external moving parts are installed during on-site construction, the internal and external moving parts can be directly screwed or inserted into the nested block through the opening, which is convenient for installation.
[0010] Furthermore, the internal and external moving grooves are cylindrical grooves, and internal threads are provided in the internal and external moving grooves. This realizes the threaded connection with the internal and external moving parts, and the screwing-in and screwing-out distances of the internal and external moving parts in the nested block are controllable, ensuring the extended length of the internal and external moving parts. If the internal and external moving parts are not threadedly connected to the internal and external moving grooves, after the internal and external moving parts extend a certain length, welding is carried out at the junction of the internal and external moving parts and the nested block to fix the position of the internal and external moving parts. At this time, the internal and external moving parts are preferably screw rods.
[0011] Furthermore, an inner and outer moving member is installed in the inner and outer moving groove. The length of the inner and outer moving member is less than that of the nested block, enabling the inner and outer moving member to be received within the nested block. Even when the inner and outer moving member is pre-embedded, it will not protrude from the outer board surface. This solution preferably prefabricates the inner and outer moving member in advance and installs the inner and outer moving member during the wall panel forming process, eliminating the need for on-site installation at the construction site of the wall, further improving the construction efficiency.
[0012] Furthermore, flanges are provided on the inner and outer moving member. The flanges are located in the inner and outer moving groove, and a blocking platform is provided on the nested block. This method is only available when prefabricating the inner and outer moving member in the wall panel in advance. A blocking interference can be formed between the flange and the blocking platform, so as to prevent the inner and outer moving member from being completely pulled out or falling off when the inner and outer moving member is pulled.
[0013] Furthermore, external threads are provided on the inner and outer moving member, and the inner and outer moving member is threadedly connected to the inner and outer moving groove.
[0014] Furthermore, the nested block passes through the connecting steel plate. The part of the nested block on the side of the concrete layer is the strengthening section. A strengthening rib is provided between the strengthening section of the nested block and the connecting steel plate, or a flange is connected to the strengthening section of the nested block. In this way, the fixing reliability between the nested block and the connecting steel plate is achieved, and the nested block passes through the connecting steel plate, and both sides of the connecting steel plate can be welded to the nested block.
[0015] Furthermore, a tie plate or tie bar is fixed on the connecting steel plate. The tie plate or tie bar is located in the concrete layer. The tie plate and tie bar can be straight anchors or bent anchors to increase the embedded depth in the concrete layer and improve the fixing strength of the connecting member.
[0016] In addition, the present utility model also provides a wall structure, including the above-mentioned integrated thermal insulation structure wall panel, and further including a dry hanging curtain wall. A keel is provided on the dry hanging curtain wall, and the keel is connected to the inner and outer moving member in the connecting member. The connecting part between the inner and outer moving member and the keel can be of various shapes, such as slot type, cross type, straight plate type, etc., to adapt to different types of keel structures. The installation is convenient, greatly improving the installation efficiency of the dry hanging curtain wall. This setting method of the connecting member has higher connecting strength and strong bearing capacity, ensuring the reliability of the dry hanging curtain wall.
[0017] The above-mentioned integrated thermal insulation structure wall panel is prefabricated and formed in the factory, and the above-mentioned wall structure is assembled. The prefabricated integrated thermal insulation structure wall panel in the factory is used for on-site installation.
[0018] In addition, the present utility model provides a wall structure, which is different from the above-mentioned wall structure and is cast in situ at the construction site. Specifically, the wall structure includes a concrete layer cast and formed at the construction site. An insulation layer is provided on the outer side of the concrete layer, and a dry hanging curtain wall is provided on the outer side of the insulation layer. It is characterized in that it further includes a connecting piece, a part of the connecting piece is located in the concrete layer, and the other part of the connecting piece is located in the insulation layer. An internal and external moving groove is provided on the connecting piece, and an internal and external moving part is installed in the internal and external moving groove. The connecting piece does not protrude from the outer plate surface of the insulation layer. An internal and external moving groove is provided on the connecting piece, and an internal and external moving part is installed in the internal and external moving groove. A keel is provided on the dry hanging curtain wall, and the keel is connected to the internal and external moving part (which can be directly connected or indirectly connected through a part adapted to the keel). As for the structure and setting method of the connecting piece and the internal and external moving part, reference can be made to the above description. During construction, install the insulation layer, support the inner formwork and the outer formwork. The insulation layer is on the inner side of the outer formwork and fits with the outer formwork. A casting cavity is formed between the insulation layer and the inner formwork. Pour concrete into the casting cavity to form a concrete layer. The connecting piece is installed on the insulation layer before pouring the concrete. Since the connecting piece does not protrude from the outer plate surface of the insulation layer, it can ensure that the outer plate surface of the insulation layer fits with the outer formwork, and avoid the deformation and movement of the insulation layer when pouring concrete. The internal and external moving part can be prefabricated in the connecting piece in advance and hidden in the internal and external moving groove when not in use, and pulled out or sucked out by a magnet when in use; the internal and external moving part can also be installed when installing the dry hanging curtain wall. Find the connecting piece on the insulation layer and insert or screw the internal and external moving part into the connecting piece.
[0019] The present utility model also provides a wall structure, which is different from the wall structure in the previous paragraph. A protective layer is provided on the outer side of the insulation layer, and the protective layer is generally formed by the solidification of concrete. Specifically, the wall structure includes a concrete layer cast and formed at the construction site. An insulation layer is provided on the outer side of the concrete layer, a protective layer is provided on the outer side of the insulation layer, and a dry hanging curtain wall is provided on the outer side of the protective layer. It is characterized in that it further includes a connecting piece, a part of the connecting piece is located in the concrete layer, and the other part of the connecting piece is located in the insulation layer and the protective layer. The connecting piece does not protrude from the outer plate surface of the protective layer. An internal and external moving groove is provided on the connecting piece, and an internal and external moving part is installed in the internal and external moving groove. The internal and external moving part extends out of the outer plate surface of the protective layer. A keel is provided on the dry hanging curtain wall, and the keel is connected to the internal and external moving part (which can be directly connected or indirectly connected through a part adapted to the keel). As for the structure and setting method of the connecting piece and the internal and external moving part, reference can be made to the above description. Similarly, since the connecting piece does not protrude from the outer plate surface of the protective layer, it can ensure that the outer plate surface of the protective layer fits with the outer formwork, and avoid the deformation and movement of the insulation layer when pouring concrete. The internal and external moving part can be prefabricated in the connecting piece in advance and hidden in the internal and external moving groove when not in use, and pulled out or sucked out by a magnet when in use; the internal and external moving part can also be installed when installing the dry hanging curtain wall. Find the connecting piece on the protective layer and insert or screw the internal and external moving part into the connecting piece.
[0020] Compared with the cast-in-situ wall structure, in the prefabricated wall structure, the connectors are prefabricated on the insulation integrated wallboard in the factory, with stronger standardization and normalization, higher efficiency, and more standard prefabricated positions of the connectors.
[0021] As can be seen from the above technical solutions, the utility model has the following advantages:
[0022] This solution provides an insulation structure integrated wallboard and a wall structure. After the insulation structure integrated wallboard is formed in the factory, it is directly transported to the construction site for installation. If the internal and external moving parts have been prefabricated on the connectors, the internal and external moving parts can be directly pulled out or screwed out during use and connected to the keel of the dry hanging curtain wall. If the internal and external moving parts are not prefabricated, the internal and external moving parts can be inserted into the connectors at the construction site. The internal and external moving parts are inserted into the connectors from the outer panel surface of the protective layer and connected to the connectors, eliminating the work of punching expansion bolts on site, greatly improving the construction efficiency, and because the connectors are prefabricated in the factory, the positions of the connectors can be well guaranteed, facilitating the connection with the keel on the dry hanging curtain wall and also avoiding the non-standardization of on-site construction and installation of the connectors; this setting method of the connectors has higher connection strength and strong bearing capacity, and also ensures the reliability of the dry hanging curtain wall.

Specific embodiment
[0040] In order to make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of this patent. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other. Specific embodiment 1
[0042] As Figure 1 , Figure 2 , Figures 5 to 12 shown, this specific embodiment provides an integrated wall panel with a thermal insulation structure, including a concrete layer 1 and a thermal insulation layer 2, and the thermal insulation layer 2 is located outside the concrete layer 1; it also includes a connecting member 4, a part of the connecting member 4 is located in the concrete layer 1, and the other part of the connecting member 4 is located in the thermal insulation layer 2. A part of the connecting member 4 is located in the concrete layer 1, which on the one hand ensures the installation depth of the connecting member 4, and on the other hand can ensure the firmness of the fixation of the connecting member 4 and improve the load-bearing capacity; an inner and outer moving groove 9 is provided on the connecting member 4, and the inner and outer moving groove 9 is used to install the inner and outer moving member 5 and provide a moving space for the inner and outer moving member 5 in the inner and outer directions. An opening 15 is provided at the outer end of the connecting member 4, and a hole (the hole and the opening 15 can be flush on the outer board surface, Figure 1 and Figure 2 both show this way. Of course, they can also be non-flush) is provided at the corresponding position of the outer board surface of the thermal insulation layer 2, so that the inner and outer moving member 5 passes through and extends to connect the keel of the dry-hanging curtain wall 16; the connecting member 4 does not protrude from the outer board surface of the thermal insulation layer 2, ensuring the flatness of the outer board surface of the thermal insulation layer 2, and can fit with the thermal insulation layer 2 when supporting the outer formwork, avoiding deformation of the thermal insulation layer 2 during concrete pouring. In this embodiment, the concrete layer 1 is generally about 200 mm, and the thermal insulation layer 2 is an A-level fireproof thermal insulation board. Since this solution meets the fire protection requirements, there is no need to provide a protective layer 3 outside the thermal insulation layer 2.
[0043] Among them, the connecting member 4 includes a connecting steel plate 7 and a nested block 8. The nested block 8 is used to install the inner and outer moving member 5. The nested block 8 is fixedly connected to the connecting steel plate 7. The cross-sectional area of the connecting steel plate 7 is larger than that of the nested block 8. The connecting steel plate 7 is located inside the thermal insulation layer 2 and in the concrete layer 1, and the nested block 8 is located in the thermal insulation layer 2. During installation, the connecting steel plate 7 can be attached to the thermal insulation layer 2 to limit the nested block 8. And due to its large cross-sectional area, when poured in the concrete layer 1, it has better anti-pulling force, improving the bearing capacity of the connecting member 4. Here, the nested block 8 can be columnar, plate-shaped, or of other common shapes. The inner and outer moving groove 9 is located in the nested block 8. Here, the cylindrical cavity of the nested block 8 can be regarded as the inner and outer moving groove 9. The nested block 8 is horizontally arranged and is generally perpendicular to the outer plate surface of the thermal insulation layer 2. The opening 15 is provided at one end of the nested block 8 away from the connecting steel plate 7 (i.e., the outer end of the nested block 8). The opening 15 communicates with the inner and outer moving groove 9, enabling the inner and outer moving member 5 to be located in the nested block 8, avoiding interference and facilitating the movement of the inner and outer moving member 5. If the inner and outer moving member 5 is installed during on-site construction, the inner and outer moving member 5 can be directly screwed or inserted into the nested block 8 through the opening 15, which is convenient for installation. The inner and outer moving member 5 is installed in the inner and outer moving groove 9. In this embodiment, the inner and outer moving member 5 is prefabricated in advance and installed when the wall panel is formed, eliminating the need for on-site installation at the wall construction site and further improving the construction efficiency. Among them, the inner and outer moving member 5 is provided with a flange 11. The flange 11 is located in the inner and outer moving groove 9. The nested block 8 is provided with a blocking platform 10. A blocking interference can be formed between the flange 11 and the blocking platform 10, so that the inner and outer moving member 5 can be prevented from being completely pulled out or falling off when the inner and outer moving member 5 is pulled.
[0044] Among them, in some embodiments, the inner and outer moving groove 9 is a cylindrical groove. The inner and outer moving groove 9 is provided with internal threads, and the inner and outer moving member 5 is provided with external threads 14 (see Figure 12 ). The inner and outer moving member 5 is threadedly connected to the inner and outer moving groove 9. The screwing-in and screwing-out distances of the inner and outer moving member 5 in the nested block 8 are controllable, ensuring the extended length of the inner and outer moving member 5. In some other embodiments, the inner and outer moving member 5 is not threadedly connected to the inner and outer moving groove 9 but is of a pull-out type. After the inner and outer moving member 5 is pulled out a certain length, welding is performed at the junction of the inner and outer moving member 5 and the nested block 8 to fix the position of the inner and outer moving member 5.
[0045] Among them, the nested block 8 passes through the connecting steel plate 7. The part of the nested block 8 passing through the connecting steel plate 7 on the side in the concrete layer 1 is the strengthening section. A strengthening rib 12 (see Figure 10 ) is provided between the strengthening section of the nested block 8 and the connecting steel plate 7, or a flange 13 (see Figure 11 ) is connected to the strengthening section of the nested block 8. In this way, the firmness of the connection between the nested block 8 and the connecting steel plate 7 is achieved, and since the nested block 8 passes through the connecting steel plate 7, both sides of the connecting steel plate 7 can be welded to the nested block 8.
[0046] In addition, a tie plate or tie bars 6 are fixed on the connecting steel plate 7, and the tie plate or tie bars 6 are located in the concrete layer 1. The tie plate and tie bars 6 can be straight or bent to increase the embedded depth in the concrete layer 1 and improve the fixing strength of the connector 4. Specific Embodiment 2
[0048] As Figures 3 to 12 shown, this specific embodiment provides a thermal insulation structure integrated wall panel different from Specific Embodiment 1, including a concrete layer 1, a thermal insulation layer 2 and a protective layer 3 (generally referred to as a sandwich precast wall panel in the art). The thermal insulation layer 2 is located outside the concrete layer 1, and the protective layer 3 is located outside the thermal insulation layer 2; it also includes a connector 4, a part of the connector 4 is located in the concrete layer 1, another part of the connector 4 is located in the thermal insulation layer 2 and the protective layer 3, an inner and outer moving groove 9 is provided on the connector 4, an opening 15 is provided at the outer end of the connector 4, a hole is provided at the position corresponding to the opening 15 on the outer plate surface of the protective layer 3, and the connector 4 does not protrude from the outer plate surface of the protective layer 3. In this solution, the thermal insulation layer 2 can use a Class B fireproof thermal insulation board. To meet the fireproof requirements, a protective layer 3 is provided outside the thermal insulation layer 2 to form a sandwich thermal insulation wall panel, and the protective layer 3 is formed by the solidification of concrete.
[0049] Among them, the connecting member 4 includes a connecting steel plate 7 and a nested block 8. The nested block 8 is used to install the inner and outer moving member 5. The nested block 8 is fixedly connected to the connecting steel plate 7. The cross-sectional area of the connecting steel plate 7 is larger than that of the nested block 8. The connecting steel plate 7 is located inside the thermal insulation layer 2 and in the concrete layer 1. A part of the nested block 8 is located in the thermal insulation layer 2, and the other part is located in the protective layer 3. During installation, the connecting steel plate 7 can be attached to the thermal insulation layer 2 to limit the nested block 8. And due to its large cross-sectional area, when poured in the concrete layer 1, it has good anti-pulling force, improving the load-bearing capacity of the connecting member 4. Here, the nested block 8 can be cylindrical, or plate-shaped, or of other common shapes. The inner and outer moving groove 9 is located in the nested block 8. Here, the cylindrical cavity of the nested block 8 can be regarded as the inner and outer moving groove 9. The nested block 8 is horizontally arranged and is generally perpendicular to the outer plate surface of the protective layer 3. The opening 15 is provided at one end of the nested block 8 away from the connecting steel plate 7 (i.e., the outer end of the nested block 8). The opening 15 communicates with the inner and outer moving groove 9, enabling the inner and outer moving member 5 to be located in the nested block 8, avoiding interference and facilitating the movement of the inner and outer moving member 5. If the inner and outer moving member 5 is installed during on-site construction, the inner and outer moving member 5 can be directly screwed or inserted into the nested block 8 through the opening 15, which is convenient for installation. The inner and outer moving member 5 is installed in the inner and outer moving groove 9. In this embodiment, the inner and outer moving member 5 is prefabricated in advance and installed when the wall panel is formed, without the need for on-site installation at the wall construction site, further improving the construction efficiency. Among them, a flange 11 is provided on the inner and outer moving member 5. The flange 11 is located in the inner and outer moving groove 9. A blocking platform 10 is provided on the nested block 8. A blocking interference can be formed between the flange 11 and the blocking platform 10, so as to prevent the inner and outer moving member 5 from being completely pulled out or falling off when the inner and outer moving member 5 is pulled.
[0050] Among them, in some embodiments, the inner and outer moving groove 9 is a cylindrical groove. The inner and outer moving groove 9 is provided with internal threads, and the outer thread 14 is provided on the inner and outer moving member 5 (see Figure 12 ). The inner and outer moving member 5 is threadedly connected to the inner and outer moving groove 9. The screwing-in and screwing-out distances of the inner and outer moving member 5 in the nested block 8 are controllable, ensuring the extended length of the inner and outer moving member 5. In some other embodiments, the inner and outer moving member 5 is not threadedly connected to the inner and outer moving groove 9 but is of a pull-out type. After the inner and outer moving member 5 is pulled out a certain length, welding is performed at the junction of the inner and outer moving member 5 and the nested block 8 to fix the position of the inner and outer moving member 5.
[0051] Among them, the nested block 8 passes through the connecting steel plate 7. The part of the nested block 8 passing through the connecting steel plate 7 on the side in the concrete layer 1 is the strengthening section. A strengthening rib 12 is provided between the strengthening section of the nested block 8 and the connecting steel plate 7 (see Figure 10 ) or a flange 13 is connected to the strengthening section of the nested block 8 (see Figure 11), in this way, the fixing reliability between the nested block 8 and the connecting steel plate 7 is achieved, and the nested block 8 passes through the connecting steel plate 7, and both sides of the connecting steel plate 7 can be welded to the nested block 8.
[0052] In addition, a tie plate or tie bar 6 is fixed on the connecting steel plate 7. The tie plate or tie bar 6 is located in the concrete layer 1. The tie plate and tie bar 6 can be straight or bent to increase the embedded depth in the concrete layer 1 and improve the fixing strength of the connector 4. Specific Embodiment 3
[0054] The difference between this specific embodiment and Specific Embodiments 1 and 2 is that: when the integrated thermal insulation and structural wall panel is manufactured in the factory, the inner and outer moving parts 5 are not prefabricated (see Figures Figure 13 and Figure 14 ), but when the integrated thermal insulation and structural wall panel is installed on the construction site, the inner and outer moving parts 5 are screwed or inserted through the opening 15 of the connector 4. At this time, no flange 11 is provided on the inner and outer moving parts 5. A more preferred way is that the inner and outer moving parts 5 are provided with external threads 14 and are threadedly connected to the nested block 8, and can be directly screwed in through the holes on the outer surface of the thermal insulation board and the opening 15 of the nested block 8. Specific Embodiment 4
[0056] As Figure 15 shown, this specific embodiment provides a wall structure, which includes the integrated thermal insulation and structural wall panel described in Specific Embodiment 1 or 2 or 3, and also includes a dry-hanging curtain wall 16. A keel is provided on the dry-hanging curtain wall 16, and the keel is connected to the inner and outer moving parts 5 in the connector 4. The connection part between the inner and outer moving parts 5 and the keel can be of various shapes, such as a slot type (see Figure 6 、 Figure 7 ), a cross type (see Figure 8 ), a straight plate type (see Figure 9 ), etc., to adapt to different types of keel structures. Specific Embodiment 5
[0058] As Figure 15As shown in the figure, this specific embodiment provides a wall structure, which is different from the wall structure in Specific Embodiment 4 and is cast on-site during construction. Specifically, the wall structure includes a concrete layer 1 cast and formed at the construction site. A heat-insulating layer 2 is provided on the outer side of the concrete layer 1, and a dry-hanging curtain wall 16 is provided on the outer side of the heat-insulating layer 2. It is characterized in that it further includes a connecting member 4. A part of the connecting member 4 is located in the concrete layer 1, and the other part of the connecting member 4 is located in the heat-insulating layer 2. An inner and outer moving groove 9 is provided on the connecting member 4, and an inner and outer moving member 5 is installed in the inner and outer moving groove 9. The connecting member 4 does not protrude from the outer plate surface of the heat-insulating layer 2. An inner and outer moving groove 9 is provided on the connecting member 4, and an inner and outer moving member 5 is installed in the inner and outer moving groove 9. A keel is provided on the dry-hanging curtain wall 16, and the keel is connected to the inner and outer moving member 5 (which can be directly connected or indirectly connected through a member adapted to the keel). As for the structure and setting method of the connecting member 4 and the inner and outer moving member 5, reference can be made to the description in the above specific embodiment. During construction, install the heat-insulating layer 2, support the inner formwork and the outer formwork. The heat-insulating layer 2 is on the inner side of the outer formwork and fits with the outer formwork. A casting cavity is formed between the heat-insulating layer 2 and the inner formwork. Pour concrete into the casting cavity to form the concrete layer 1. The connecting member 4 is installed on the heat-insulating layer 2 before pouring the concrete. Since the connecting member 4 does not protrude from the outer plate surface of the heat-insulating layer 2, it can ensure that the outer plate surface of the heat-insulating layer 2 fits with the outer formwork. The inner and outer moving member 5 can be prefabricated in the connecting member 4 in advance and hidden in the inner and outer moving groove 9 when not in use, and pulled out or sucked out with a magnet when in use; the inner and outer moving member 5 can also be installed when installing the dry-hanging curtain wall 16. Locate the connecting member 4 on the heat-insulating layer 2 and insert or screw the inner and outer moving member 5 into the connecting member 4. Specific Embodiment 6
[0060] As Figure 16As shown, although the wall structure provided in this specific embodiment is also cast-in-place, it is different from the wall structure in Embodiment 5. In the wall structure of this specific embodiment, a protective layer 3 is provided on the outer side of the insulation layer 2, and the protective layer 3 is generally formed by the solidification of concrete. Specifically, the wall structure includes a concrete layer 1 formed by casting on the construction site. An insulation layer 2 is provided on the outer side of the concrete layer 1, a protective layer 3 is provided on the outer side of the insulation layer 2, and a dry-hanging curtain wall 16 is provided on the outer side of the protective layer 3. It is characterized in that it further includes a connecting member 4. A part of the connecting member 4 is located in the concrete layer 1, and the other part of the connecting member 4 is located in the insulation layer 2 and the protective layer 3. The connecting member 4 does not protrude from the outer plate surface of the protective layer 3. An inner and outer moving groove 9 is provided on the connecting member 4, and an inner and outer moving member 5 is installed in the inner and outer moving groove 9. The inner and outer moving member 5 extends out of the outer plate surface of the protective layer 3. A keel is provided on the dry-hanging curtain wall 16, and the keel is connected to the inner and outer moving member 5 (it can be directly connected or indirectly connected through a member adapted to the keel). As for the structure and setting method of the connecting member 4 and the inner and outer moving member 5, reference can be made to the description in the above specific embodiment. Similarly, since the connecting member 4 does not protrude from the outer plate surface of the protective layer 3, it can ensure that the outer plate surface of the protective layer 3 fits with the outer formwork, avoiding the deformation and movement of the insulation layer 2 when pouring concrete. The inner and outer moving member 5 can be prefabricated in the connecting member 4 in advance and hidden in the inner and outer moving groove 9 when not in use, and pulled out or sucked out by a magnet when in use; the inner and outer moving member 5 can also be installed when installing the dry-hanging curtain wall 16. Find the connecting member 4 on the protective layer 3 and insert or screw the inner and outer moving member 5 into the connecting member 4.
