[0002] The light steel keel partition wall system is commonly used in indoor enclosing structures, and the system is required to have a certain bending resistance and thermal insulation ability. Currently known light steel keel partition walls mainly provide thermal insulation ability through gypsum boards, and add a large number of longitudinal and transverse keels to provide bending resistance. However, the addition of a large number of keels also increases the heat transfer coefficient of the system, resulting in heat loss. Moreover, although the overall bending stiffness of the system is improved, it also causes waste of materials, increases the manufacturing cost, and increases the construction difficulty and time cost. In addition, the gypsum board used as a thermal insulation material often requires complex cutting, laying and fixing, which has high requirements for construction technology and is difficult to ensure the consistency and stability of the thermal insulation effect.

[0020] Two concrete slabs are semi-rigidly connected through the springs in the limiting mechanism and the light steel keels at both ends, which improves the bending resistance of the system. At the same time, when subjected to external forces, the springs can provide appropriate deformation and energy absorption, improving the seismic resistance and durability of the hollow composite light steel keel sandwich thermal insulation wall panel, effectively preventing the offset or dislocation of the concrete slabs, ensuring the stability of the hollow composite light steel keel sandwich thermal insulation wall panel, and being beneficial to improving the installation accuracy.

In the later stage, the cast-in-place thermal insulation material undergoes shrinkage, causing the springs to compress to provide thrust for the system to relieve the cracks generated in the later stage of the cast-in-place thermal insulation material, ensuring the stability and consistency of the thermal insulation effect, that is, improving the thermal insulation effect of the hollow composite light steel keel sandwich thermal insulation wall panel.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] The object of the present invention is to provide a hollow laminated light steel keel sandwich thermal insulation wallboard and its installation method, so as to solve the problems existing in the prior art. Through the setting of the spring, semi-rigid connection is carried out between the two concrete slabs, which can effectively improve the bending resistance and stability of the system. After filling the internal thermal insulation material, the thermal insulation stability and consistency are high, and the thermal insulation effect can be effectively improved.

[0038] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Please refer to Figures 1 to 11 As shown, a hollow laminated light steel keel sandwich thermal insulation wallboard is provided, which includes a concrete slab 1, a light steel keel 2 and a limiting mechanism 4. The limiting mechanism 4 includes a first limiting member, a second limiting member and a spring 45. The first limiting member and the second limiting member are respectively connected to the concrete slab 1, and the two side concrete slabs 1 can be divided into a first concrete slab 11 and a second concrete slab 12. A spring 45 is arranged between the first limiting member and the second limiting member. Both ends of the two side concrete slabs 1 are connected by the light steel keel 2. A filling space for filling the thermal insulation material 3 is formed by enclosing between the two side concrete slabs 1 and the two end light steel keels 2. The thermal insulation material 3 can be filled into the filling space by pouring; in this application, the two concrete slabs 1 are semi-rigidly connected through the spring 45 in the limiting mechanism 4 and the light steel keels 2 at both ends. While improving the bending resistance of the system, when subjected to external forces, the spring 45 can provide appropriate deformation and energy absorption, improving the seismic resistance and durability of the hollow laminated light steel keel sandwich thermal insulation wallboard, effectively preventing the offset or dislocation of the concrete slab 1, ensuring the stability of the hollow laminated light steel keel sandwich thermal insulation wallboard, and being beneficial to improving the installation accuracy; in addition, the spring 45 is initially in its original length state and is combined with the concrete slab 1. In the initial stage of casting the thermal insulation material 3, due to the hydration heat, the spring 45 elongates to provide pressure for the system to resist the micro-expansion generated by the cast-in-place thermal insulation material 3. In the later stage, the cast-in-place thermal insulation material 3 shrinks dryly, causing the spring 45 to compress to provide a thrust for the system to relieve the cracks generated by the cast-in-place thermal insulation material 3 in the later stage, ensuring the stability and consistency of the thermal insulation effect. When cooperating with the casting of the thermal insulation material 3, the fluidity of the thermal insulation material 3 enables it to be fully filled, and the thermal insulation material 3 is in close contact with each component, improving the thermal insulation effect of the hollow laminated light steel keel sandwich thermal insulation wallboard.

[0040] The first limiting member and the second limiting member can be fixedly arranged on the concrete slab 1 or detachably arranged on the concrete slab 1.

[0041] In this embodiment, the first limiting member and the second limiting member are detachably arranged on the concrete slab 1. The specific structure is as follows: The first limiting member includes a first limiting rod 42, a first limiting plate 43 and a first connecting member. The first limiting plate 43 is fixedly arranged on the first limiting rod 42. A first through hole 111 for the first limiting rod 42 to pass through is arranged on the concrete slab 1. One end of the first limiting rod 42 away from the second limiting rod 46 passes through the first through hole 111 and is detachably connected to the first connecting member. The distance between the first connecting member and the first limiting plate 43 is the same as the thickness of the concrete slab 1. The second limiting member includes a second limiting rod 46, a second limiting plate 47 and a second connecting member. The second limiting plate 47 is fixedly arranged on the second limiting rod 46. A second through hole 121 for the second limiting rod 46 to pass through is arranged on the concrete slab 1. One end of the second limiting rod 46 away from the first limiting rod 42 passes through the second through hole 121 and is detachably connected to the second connecting member. The distance between the second connecting member and the second limiting plate 47 is the same as the thickness of the concrete slab 1. The connection principles of the first limiting member and the second limiting member are the same. Both limit the two sides of the limiting plate through the connecting member to realize the connection between the limiting rod and the concrete slab 1. The detachable connection between the first limiting rod 42 and the first connecting member and between the second limiting rod 46 and the second connecting member can adopt methods such as snap connection or threaded connection.

[0042] When the limiting rod is snap-connected to the connecting member, the first connecting member is a first pressing cover 41. A first fixing protrusion 421 is arranged at the end of the first limiting rod 42 close to the first pressing cover 41. A first fixing groove 422 is arranged between the first fixing protrusion 421 and the first limiting rod 42. A first reserved groove 411 matching the first fixing protrusion 421 and the first fixing groove 422 is formed on the first pressing cover 41. The first pressing cover 41 is buckled on the first fixing protrusion 421 and the first fixing groove 422 through the first reserved groove 411. The second connecting member is a second pressing cover 48. A second fixing protrusion 462 is arranged at the end of the second limiting rod 46 close to the second pressing cover 48. A second fixing groove 463 is arranged between the second fixing protrusion 462 and the second limiting rod 46. A second reserved groove 481 matching the second fixing protrusion 462 and the second fixing groove 463 is formed on the second pressing cover 48. The second pressing cover 48 is buckled on the second fixing protrusion 462 and the second fixing groove 463 through the second reserved groove 481. The pressing cover itself has a deformation self-recovery function. During actual connection, it can be buckled on the fixing protrusion and the fixing groove by pressing the pressing cover.

[0043] The first fixing protrusion 421, the first fixing groove 422 and the first limiting rod 42 are integrally arranged, and the second fixing protrusion 462, the second fixing groove 463 and the second limiting rod 46 are integrally arranged. The integral arrangement method can improve the structural strength.

[0044] The outer peripheral edge shapes of the first fixing protrusion 421 and the second fixing protrusion 462 respectively match the outer peripheral edge shapes of the first limiting rod 42 and the second limiting rod 46. When processing the fixing protrusions and the fixing grooves, by directly opening the fixing grooves on the rods, the fixing protrusions can be automatically formed.

[0045] In this embodiment, both the first limiting rod 42 and the second limiting rod 46 are cylindrical structures.

[0046] The outer side surfaces of the first fixing protrusion 421 and the second fixing protrusion 462 can be set as arc surfaces, which is convenient for buckling with the pressing cover.

[0047] The outer side surfaces of the first pressing cover 41 and the second pressing cover 48 can be set as arc surfaces, which can improve the convenience of the pressing fit with the fixing protrusions.

[0048] When the limiting rod is threadedly connected to the connecting member, the first connecting member and the second connecting member are replaced with screw caps having internal threads, and external threads are provided on the first limiting rod 42 and the second limiting rod 46. After the screw cap is threadedly connected to the limiting rod, positioning connection is achieved in cooperation with the limiting plate.

[0049] In this embodiment, a sliding groove 44 is provided on the first limiting rod 42. The sliding groove 44 matches the second limiting rod 46, and the second limiting rod 46 is slidably disposed in the sliding groove 44. A spring 45 is disposed in the sliding groove 44. One end of the spring 45 is connected to the bottom 441 of the sliding groove 44, and the other end is connected to the connecting end surface 461 of the second limiting rod 46. The provision of the sliding groove 44 limits the radial movement of the spring 45 and ensures that the spring 45 normally expands and contracts to provide axial force for the two side concrete slabs 1.

[0050] It can be provided that the two side concrete slabs 1 are connected by a plurality of limiting mechanisms 4, and the plurality of limiting mechanisms 4 are evenly distributed, further improving the stability and bending resistance of the overall hollow composite light steel keel sandwich insulation wall panel.

[0051] In this embodiment, the light steel keel 2 includes a first positioning plate 21, a second positioning plate 22, a third positioning plate 23, and a fourth positioning plate 24 which are integrally provided. Both ends of the fourth positioning plate 24 are sequentially connected to the third positioning plate 23, the second positioning plate 22, and the first positioning plate 21 to form a stepped structure. The two end first positioning plates 21 are arranged in parallel, the two end second positioning plates 22 are located in the same plane, the two end third positioning plates 23 are arranged in parallel, the first positioning plate 21 is connected to the concrete slab 1, and the end surface of the concrete slab 1 is in contact with the second positioning plate 22, generating a diaphragm effect and improving its overall performance. This design enables convenient and accurate installation between adjacent hollow composite light steel keel sandwich insulation wall panels, improving the construction efficiency and construction accuracy.

[0052] When the single hollow laminated light steel keel sandwich thermal insulation wall panel is installed on-site or pre-assembled in the factory, first pass the first limiting rod 42 and the second limiting rod 46 of the limiting mechanism 4 through the concrete slabs 1 on both sides and connect the first pressing cover 41 and the second pressing cover 48. Then install the light steel keels 2 on both sides. The first positioning plate 21 of the light steel keel 2 is connected to the concrete slab 1 by self-tapping screw B11. After the connection is completed, pour the thermal insulation material 3 into the filling space. The thermal insulation material 3 can be the thermal insulation material 3 proposed in CN118930161A, CN117567118A or other applicable thermal insulation materials 3.

[0053] The present invention also provides an installation scheme for the above-mentioned hollow laminated light steel keel sandwich thermal insulation wall panel, including the following steps:

[0054] S1: Arrange two hollow laminated light steel keel sandwich thermal insulation wall panels at intervals in the same plane, and the fourth positioning plates 24 of the two hollow laminated light steel keel sandwich thermal insulation wall panels are arranged opposite to each other;

[0055] S2: Judge whether another hollow laminated light steel keel sandwich thermal insulation wall panel needs to be installed vertically between the two arranged hollow laminated light steel keel sandwich thermal insulation wall panels according to requirements. If not, install the connecting plate 13 between the second positioning plates 22 of the two hollow laminated light steel keel sandwich thermal insulation wall panels, connect the connecting plate 13 to the third positioning plate 23, and after the connection is completed, fill the thermal insulation material 3 into the filling spaces of the two hollow laminated light steel keel sandwich thermal insulation wall panels; if so, take another hollow laminated light steel keel sandwich thermal insulation wall panel for installation;

[0056] S3: Take another hollow laminated light steel keel sandwich thermal insulation wall panel, insert the fourth positioning plate 24 of the light steel keel 2 of this hollow laminated light steel keel sandwich thermal insulation wall panel between the two arranged hollow laminated light steel keel sandwich thermal insulation wall panels, and make connections. After the connection is completed, assemble the concrete slab 1, the light steel keel 2 and the limiting mechanism 4 of this hollow laminated light steel keel sandwich thermal insulation wall panel. After the assembly is completed, fill the thermal insulation material 3 into the filling space of the hollow laminated light steel keel sandwich thermal insulation wall panel;

[0057] S4: Fill the thermal insulation material 3 into the interval space between the hollow laminated light steel keel sandwich thermal insulation wall panels.

[0058] The connecting plate 13 in step S3 can also be selected as the concrete slab 1.

[0059] For example, in the case of assembling a two-sided hollow laminated light steel keel sandwich thermal insulation wall panel: For a cured two-sided hollow laminated light steel keel sandwich thermal insulation wall panel, connecting plates 13 are placed on the outer sides of the second positioning plates 22 and the third positioning plates 23 at both ends of the light steel keel 2 on one side, and the light steel keel 2 is fixed to the connecting plate 13 with self-tapping screws III B23; the outer sides of the second positioning plates 22 and the third positioning plates 23 of the light steel keel 2 on one side of the other cured two-sided hollow laminated light steel keel sandwich thermal insulation wall panel are inserted between the two connecting plates 13, and the connecting plate 13 is fixed to the light steel keel 2 with self-tapping screws III B23; finally, thermal insulation material 3 is poured into the internal filling space of the two-sided hollow laminated light steel keel sandwich thermal insulation wall panel and the internal spaced space between the two-sided hollow laminated light steel keel sandwich thermal insulation wall panel and the two connecting plates 13, and the first positioning plate 21 of each two-sided hollow laminated light steel keel sandwich thermal insulation wall panel is connected to the concrete plate 1 with self-tapping screws II B21.

[0060] In the case of assembling a three-sided hollow laminated light steel keel sandwich thermal insulation wall panel: The difference from the assembling method of the two-sided hollow laminated light steel keel sandwich thermal insulation wall panel is that one side connecting plate 13 is replaced with a two-sided hollow laminated light steel keel sandwich thermal insulation wall panel.

[0061] The specific assembly method is as follows: For a cured hollow laminated light steel keel sandwich thermal insulation wallboard, place a connecting plate 13 outside the second positioning plate 22 and the third positioning plate 23 at one end of the light steel keel 2 on one side thereof, and fix the light steel keel 2 and the connecting plate 13 with self-tapping screw five B33; make the outside of the second positioning plate 22 and the third positioning plate 23 of the light steel keel 2 on one side of the other cured hollow laminated light steel keel sandwich thermal insulation wallboard closely adhere to the end of the connecting plate 13, and fix the connecting plate 13 and the light steel keel 2 with self-tapping screw five B33. At this time, the interval between the fourth positioning plates 24 of the two hollow laminated light steel keel sandwich thermal insulation wallboards is equal to the width of the fourth positioning plate 24. Take another hollow laminated light steel keel sandwich thermal insulation wallboard, insert the fourth positioning plate 24 of the light steel keel 2 of this hollow laminated light steel keel sandwich thermal insulation wallboard between the two already arranged hollow laminated light steel keel sandwich thermal insulation wallboards. At this time, the third positioning plate 23 of this hollow laminated light steel keel sandwich thermal insulation wallboard closely adheres to the fourth positioning plate 24 of the other hollow laminated light steel keel sandwich thermal insulation wallboards, the second positioning plate 22 of this hollow laminated light steel keel sandwich thermal insulation wallboard closely adheres to the third positioning plate 23 of the other hollow laminated light steel keel sandwich thermal insulation wallboards, and the first positioning plate 21 of this hollow laminated light steel keel sandwich thermal insulation wallboard closely adheres to the second positioning plate 22 of the other hollow laminated light steel keel sandwich thermal insulation wallboards. Fix the third positioning plate 23 of this hollow laminated light steel keel sandwich thermal insulation wallboard and the fourth positioning plate 24 of the other hollow laminated light steel keel sandwich thermal insulation wallboards with self-tapping screw six B34. Finally, assemble the concrete slab 1, the light steel keel 2 and the limiting mechanism 4 of this hollow laminated light steel keel sandwich thermal insulation wallboard. After assembly, fill the filling space of the hollow laminated light steel keel sandwich thermal insulation wallboard and the interval space between the three hollow laminated light steel keel sandwich thermal insulation wallboards and the connecting plate 13 with thermal insulation material 3. Connect the first positioning plate 21 of each hollow laminated light steel keel sandwich thermal insulation wallboard and the concrete slab 1 with self-tapping screw four B31.

[0062] In the case of the assembly of the four-sided hollow laminated light steel keel sandwich thermal insulation wall panel: The difference from the assembly method of the three-sided hollow laminated light steel keel sandwich thermal insulation wall panel lies in replacing the connecting plate 13 with the hollow laminated light steel keel sandwich thermal insulation wall panel. The replacement method is the same as the method of replacing the connecting plate 13 with the hollow laminated light steel keel sandwich thermal insulation wall panel in the assembly method of the three-sided hollow laminated light steel keel sandwich thermal insulation wall panel. The hollow laminated light steel keel sandwich thermal insulation wall panels used to replace the connecting plate 13 are all first connected by self-tapping screws seven B44 between the third positioning plate 23 of the light steel keel 2 and the fourth positioning plates 24 of the two-sided hollow laminated light steel keel sandwich thermal insulation wall panels. After the connection is completed, the concrete board 1, the light steel keel 2 and the limiting mechanism 4 of the hollow laminated light steel keel sandwich thermal insulation wall panel to replace the connecting plate 13 are assembled. After the overall assembly is completed, thermal insulation materials 3 are filled in the filling space of the hollow laminated light steel keel sandwich thermal insulation wall panel and in the spaced spaces between the four hollow laminated light steel keel sandwich thermal insulation wall panels and the connecting plate 13.
