Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to an energy-saving building cast-in-situ exterior wall insulation structure and a construction method. Background Art

[0002] With the rapid development of the construction industry, prefabricated and modular buildings are the product of the development of scientific and technological achievements. It is a type of building that uses factory assembly lines to manufacture all the components needed for a house, and then transports them to the construction site for on-site hoisting and splicing. The outer surface of the building is usually covered with a layer of insulation board, exterior wall insulation board, also called horizon building exterior wall structure integrated board.

[0003] The traditional exterior wall insulation system uses adhesives to stick the insulation board on the base wall, and then uses expansion bolts to assist in fixing, apply a surface layer, and finally construct a finishing layer. This insulation system requires the base wall to have high strength. The insulation system is connected to the wall through adhesives to ensure the safety of the system. However, in prefabricated buildings, the walls are prefabricated in the factory, and most of them are cement fiber boards with cavities on the inside or aerated concrete and other materials. The strength is relatively low and usually cannot meet the strength required for bonding and anchoring of the exterior wall insulation system. Quality risks such as loose bonding and falling of the insulation board are prone to occur, and the insulation board is prone to warping and corner warping, which urgently needs to be improved.

[0004] The structure of a cast-in-place insulated wall is an inner wall layer, an insulation layer, and an outer wall layer. In addition to using effective insulation boards for the insulation layer, the insulation layer also features steel mesh installed on both sides. The steel mesh is strong and bonds better with the mortar in the insulation layer, acting somewhat like reinforced concrete, making the protective layer stronger and better protecting the insulation board. It can also better withstand the adhesion of the outer layer material, preventing cracking and deformation of the wall surface. Ensuring the vertical fixing structure of the insulation board in existing cast-in-place insulated walls can lead to loose mortar leakage at the joints due to impact and vibration during concrete pouring, significantly compromising the insulation effect. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a cast-in-place, disassembly-free insulation structure to ensure the vertical stability of the insulation board during the casting process and prevent the mortar from loosening and leaking at the joints to affect the insulation effect.

[0006] In order to solve the above technical problems, the inventors have come up with the technical solution of the present invention through practice and summary. The present invention adopts the following technical solution:

[0007] An energy-saving cast-in-place exterior wall insulation structure for a building comprises a concrete wall, an insulation board, an interior panel, and an exterior panel. The insulation board is fixed to the outside of the concrete wall. A first reference structure is installed on the outside of the insulation board, and a second reference structure is installed on the inside of the insulation board. The first reference structure and the second reference structure are used to vertically and evenly install the insulation board.

[0008] The first reference structure includes a telescopic body, one end of which is provided with a limit portion and the other end is provided with a connecting portion. A steel mesh is clamped in the limit portion, and a socket rib is installed on the steel mesh and is used to socket on the insulation board. The end face of the limit portion abuts against the exterior panel, and the connecting portion is threadedly connected to the outer wall of the insulation board. The telescopic body is a telescopic structure with adjustable length.

[0009] The second reference structure includes a second telescopic body, one end of which is threadedly connected to the insulation board, the other end is embedded in the concrete wall, and the free end abuts against the inner wall of the interior panel.

[0010] Furthermore, a connecting groove is provided on the side of the insulation board, and a seal is installed between the connecting grooves of adjacent insulation boards. The seal is used to be sealed and installed in the connecting groove. A through-connecting body is provided at the opening of the connecting groove. The assembly includes two symmetrically distributed assemblies and an X-shaped telescopic body arranged between the two assemblies. The free end of the X-shaped telescopic body is slidably arranged relative to the assembly, and the two assemblies are used to interact with each other to form a through-connecting body.

[0011] Furthermore, the through-connecting body is evenly distributed with through holes, and each combination includes a main body and a pressure-applying body hingedly installed at both ends of the main body, a torsion spring 1 is installed at the hinge node of the main body and the pressure-applying body, and the two groups of main bodies are used for movably installing an X-shaped telescopic body, and the free end of each pressure-applying body is hinged to the through-body, and a torsion spring 2 is installed at the connection node of the pressure-applying body and the through-body, and the elastic coefficient of the torsion spring 2 is smaller than the elastic coefficient of the torsion spring 1, and each through-body is used to freely pass through the corresponding through hole, and the body of each pressure-applying body is hingedly installed with a driving body, and the free end of the driving body is slidably arranged on the main body, and the free end of each driving body is hinged to a linkage body, and the free ends of the two linkage bodies at corresponding positions are hinged to the same limiting body, and the limiting body is used to socket and fix the two through-bodies at corresponding positions, and the end of the limiting body is an elastic telescopic structure.

[0012] Furthermore, a limiting protrusion is provided in the middle of the connecting groove, which is used for the fitting installation of the main body. The depth of the middle of the connecting groove is greater than the depth near the opening position, and the protrusion height of the limiting protrusion is less than the depth difference between the middle of the connecting groove and the depth near the opening position.

[0013] Furthermore, the free ends of the X-shaped telescopic bodies are hinged with T-shaped sliders, which are arranged to slide relative to the body. The body is provided with a sliding groove for the sliding of the T-shaped slider, and a spring is installed in the sliding groove for flexibly connecting the T-shaped slider.

[0014] Furthermore, the ends of the through-body located at two corresponding positions on the same group of main bodies are adapted to each other, and corresponding limiting holes are provided at the areas adapted to each other. The limiting body is used to be inserted into the limiting hole, and the end of the through-body is a wedge-shaped structure.

[0015] Furthermore, both the inner wall and the outer wall of the insulation board are provided with vertical connecting grooves, and the cross section of the vertical connecting grooves is a dovetail structure or an arc structure with a larger inner side and a smaller outer side.

[0016] Furthermore, connecting heads are preset on the inner walls of the exterior panel and the interior panel, and connecting rods are connected between the two sets of connecting heads. The connecting rods are made of insulating material and pass through the insulation board.

[0017] A construction method for a cast-in-situ exterior wall insulation structure of an energy-saving building, the construction steps are as follows:

[0018] Preparation: Loft the installation edges of the interior and exterior panels on the ground, and tie the steel mesh inside the concrete wall;

[0019] Support work: Adjust the length of telescopic body 1 and telescopic body 2 so that the projection of the end away from the insulation board on the horizontal plane is flush with the installation edge line of the interior panel and exterior panel respectively. Install the connecting rod through it, and fold the end of the connecting rod upward to form a hook. Install the interior panel and exterior panel vertically downward according to the installation edge line of the interior panel and exterior panel, ensuring that the end of the connecting rod and the connector form a hook structure. Install the supporting structure on the outside of the interior panel and exterior panel;

[0020] Pouring work: Pour concrete between the interior panels and the insulation panels, and between the exterior panels and the insulation panels. After compaction treatment through vibration, remove the supporting structure after reaching the designed strength.

[0021] Furthermore, it also includes the insulation board assembly process, and the insulation board assembly steps are as follows:

[0022] By squeezing the two bodies closer to each other, the spring between the body and the free end slider of the X-shaped telescopic body will be compressed, the distance between the two bodies will be slightly larger than the thickness of the limiting protrusion, the sealing body will enter the connecting groove, the force of the two bodies will be released, and the spring between the body and the free end slider of the X-shaped telescopic body will elastically reset, driving the bodies to move away from each other. The body will act on the pressure-applying body and the through-body to first contact the side wall of the shallow connecting groove until the through-body fits on the inner wall of the limiting protrusion. By adjusting the position of the body, the through-body will automatically enter the through hole. As the spring on the body continues to reset, the through body will adapt. The end of the limiting body will be compressed during the adaptation process. When the adaptation is completed, the end of the limiting body will automatically pop outward into the limiting hole.

[0023] Compared with existing technologies, this invention offers the following advantages: It utilizes cast-in-place construction using prefabricated interior and exterior panels, eliminating the need for formwork and reducing costs while also ensuring the flatness of the panels. Reference structures 1 and 2, along with connecting rods and connectors, are added to the insulation panel to ensure vertical flatness relative to the panels. This ensures structural stability even during concrete pouring, preventing mortar leakage. A sealing structure is also added at the joint of the insulation board. By squeezing the two bodies close to each other, the spring between the body and the free end slider of the X-shaped telescopic body will be compressed. The distance between the two bodies is slightly larger than the thickness of the limiting protrusion. The sealing body enters the connecting groove, the force of the two bodies is released, and the spring between the body and the free end slider of the X-shaped telescopic body elastically resets, driving the bodies away from each other. The body will act on the pressure-applying body and the through-body to first contact the side wall of the shallow connecting groove until the through-body fits on the inner wall of the limiting protrusion. By adjusting the position of the body, the through-body will automatically enter the through-hole. As the spring on the body continues to reset, the through-body will adapt. The end of the limiting body will be compressed during the adaptation process. When the adaptation is completed, the end of the limiting body will automatically spring outward into the limiting hole, thereby ensuring that the splicing joints are mutually involved and squeezed to prevent leakage.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] Example 1, as Figures 1 to 3 As shown, an energy-saving cast-in-place exterior wall insulation structure of a building includes a concrete wall 1, an insulation board 2, an interior panel 3 and an exterior panel 4. The insulation board 2 is fixed to the outside of the concrete wall 1. A reference structure 1 is installed on the outside of the insulation board 2, and a reference structure 2 is installed on the inside. The reference structure 1 and the reference structure 2 are used to vertically and evenly install the insulation board 2;

[0035] Reference structure 1 includes a telescopic body 1 5 , with a limiting portion 52 provided at one end and a connecting portion 51 provided at the other end. A steel mesh 53 is clamped in the limiting portion 52 , and a socket rib is mounted on the steel mesh 53 for socketing on the insulation board 2 . The end face of the limiting portion 52 abuts against the exterior panel 4 , and the connecting portion 51 is threadedly connected to the outer wall of the insulation board 2 . The telescopic body 1 5 is a telescopic structure with adjustable length.

[0036] Reference structure 2 includes telescopic body 2 (6), one end of which is threaded onto insulation board 2, the other end embedded within concrete wall 1, and the free end abutting the inner wall of interior trim panel 3. By adjusting the lengths of telescopic body 2 (6) and telescopic body 1 (5), the stopper is aligned with the inner wall of the exterior panel and the end of telescopic body 2 abuts the inner wall of the interior panel. Support structures are installed on the exteriors of the interior and exterior panels, using them as removable formwork. Connectors are pre-installed on the inner walls of both exterior and interior panels 4, with connecting rods 8 connecting the two sets of connectors. Connecting rods 8 are made of insulating material and extend through insulation board 2. The vertical hooking of connecting rods 8 and the connectors secures the interior and exterior panels 3 and 4 along their thickness. After concrete pouring, a stable exterior wall insulation structure is formed.

[0037] The inner and outer walls of the insulation board 2 are both provided with vertical connecting grooves 24. The cross-section of the vertical connecting grooves 24 is a dovetail structure or an arc structure with a larger inner portion and a smaller outer portion. The vertical connecting grooves 24 facilitate the connection of the mortar between the concrete wall 1, the exterior panel 4, and the insulation board 2, and prevent the insulation board and the exterior panel 4 from falling off.

[0038] Based on the above embodiment, the following improvements are made: Figures 1 to 7 As shown, a connecting groove 21 is provided on the side of the insulation board 2, and a sealing member 7 is installed between the connecting grooves 21 of adjacent insulation boards 2. The sealing member 7 is used to be sealed and installed in the connecting groove 21. A through-connecting body 22 is provided at the opening of the connecting groove 21. The assembly includes two symmetrically distributed assemblies and an X-shaped telescopic body 71 arranged between the two assemblies. The free end of the X-shaped telescopic body 71 is slidably arranged relative to the assembly, and the two assemblies are used to interact with each other to penetrate the connecting body 22.

[0039] The through-connecting body 22 is evenly distributed with through holes. Each assembly includes a main body 72 and a pressure body 73 hingedly mounted at both ends of the main body 72. A torsion spring 1 is installed at the hinge node of the main body 72 and the pressure body 73. The two groups of main bodies 72 are used to movably install the X-shaped telescopic body 71. The free end of each pressure body 73 is hingedly connected to a through body 74. A torsion spring 2 is installed at the connection node of the pressure body 73 and the through body 74. The elastic coefficient of the torsion spring 2 is less than the elastic coefficient of the torsion spring 1. The difference in the elastic coefficient of the torsion spring can make the through body 74 fit the inner wall of the connecting groove 21 first after the distance between the two main bodies 72 becomes larger. As the distance between the two main bodies 72 continues to increase, the through-body 74 will pass through the through-connecting body 22 to complete the adaptation of the end and the adaptation lock with the limit body 77. Each through-body 74 is used to freely pass through the corresponding through hole. The body of each pressure-applying body 73 is hingedly mounted with a driving body 75. The free end of the driving body 75 is slidably arranged on the main body 72. The free end of each driving body 75 is hingedly connected to a linkage body 76. The free ends of the two corresponding linkage bodies 76 are hingedly connected to the same limit body 77. The limit body 77 is used to socket and fix the two corresponding through-bodies 74. The end of the limit body 77 is an elastic telescopic structure. When the pressure-applying body 73 deflects toward the middle, it will drive the limit body 77 to move toward the side close to the through-connecting body 22 through the driving body 75 and the linkage body 76, ensuring that the through-body 74 will eventually be locked and fixed.

[0040] A limiting protrusion 23 is provided in the middle of the connecting groove 21. This limiting protrusion 23 ensures a snug fit for the main body 72. The depth of the middle portion of the connecting groove 21 is greater than the depth near the opening, and the height of the limiting protrusion 23 is less than the difference in depth between the middle portion and the depth near the opening of the connecting groove 21. The placement of the limiting protrusion 23 ensures that the main body 72 maintains a minimum clearance within the connecting groove 21 while maintaining its compressed state.

[0041] The free ends of the X-shaped telescopic bodies 71 are hingedly connected to T-shaped sliders, which slide relative to the main body 72. The main body 72 is provided with a sliding groove for the T-shaped sliders to slide. The sliding groove is installed with a spring to flexibly connect the T-shaped sliders. The spring allows the T-shaped sliders to slide left and right along the main body, thereby achieving adjustable spacing between the two main bodies 72.

[0042] The ends of the through-body 74 located at two corresponding positions on the same group of main bodies 72 are adapted to each other, and corresponding limiting holes are provided in the areas adapted to each other. The limiting body 77 is used to be inserted into the limiting hole. The end of the through-body 74 is a wedge-shaped structure, and the wedge-shaped structure is used to squeeze the end of the limiting body 77. The structure of the limiting body 77 has a telescopic body structure with a spring.

[0043] The end of the stopper 77 will reach the socket position before the main body 72. As the distance between the main body 72 continues to increase, the through-body 74 will gradually approach, squeezing its end and forcing it to retract. At the same time, the stopper 77 will continue to move toward the side of the through-body 74. As soon as the through-body 74 is fully adapted, the elastic end of the stopper 77 will automatically enter the stopper hole to complete the fixation. To further ensure the anti-leakage effect of the splicing seam, the through-hole of the through-body 74 has a slight axial deviation. After the stopper 77 enters, the two will be coaxially matched, and the splicing seam will be compressed.

[0044] A construction method for a cast-in-situ exterior wall insulation structure of an energy-saving building, the construction steps are as follows:

[0045] Preparation: Loft the installation edges of the interior panels 3 and exterior panels 4 on the ground, and tie the steel mesh inside the concrete wall 1;

[0046] Support work: Adjust the length of the telescopic body 1 5 and the telescopic body 2 6 so that the projection of the end away from the insulation board 2 on the horizontal plane is flush with the installation edge line of the interior panel 3 and the exterior panel 4 respectively. Install the connecting rod 8 through it, fold the end of the connecting rod 8 upward to form a hook, and install the interior panel 3 and the exterior panel 4 vertically downward according to the installation edge line of the interior panel 3 and the exterior panel 4, ensuring that the end of the connecting rod 8 and the connector form a hook structure. Install the supporting structure on the outside of the interior panel 3 and the exterior panel 4;

[0047] Pouring work: Pour concrete between the interior panel 3 and the insulation panel 2, and between the exterior panel 4 and the insulation panel 2. After compaction treatment by vibration, remove the supporting structure after reaching the designed strength.

[0048] The process of assembling the insulation board 2 is also included. The steps of assembling the insulation board 2 are as follows:

[0049] By squeezing the two bodies 72 closer to each other, the spring between the body 72 and the T-shaped slider will be compressed. The distance between the two bodies 72 is slightly larger than the thickness of the limiting protrusion 23, the sealing body enters the connecting groove 21, and the force of the two bodies 72 is released. The spring between the body 72 and the free end slider of the X-shaped telescopic body 71 elastically resets, driving the bodies 72 away from each other. The body 72 will act on the pressure-applying body 73 and the through-body 74 to first contact the side wall of the shallow connecting groove 21 until the through-body 74 fits against the inner wall of the limiting protrusion 23. By adjusting the position of the body 72, the through-body 74 will automatically enter the through hole. As the spring on the body 72 continues to reset, the through body 74 adapts, and the end of the limiting body 77 will be compressed during the adaptation process. When the adaptation is completed, the end of the limiting body 77 will automatically pop outward and enter the limiting hole.

[0050] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacement may be a replacement of a portion of a structure, device, or method step, or it may be a complete technical solution. Any equivalent replacement or modification based on the technical solution and inventive concept of the present invention shall be covered by the scope of protection of the present invention.
