DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide a hollow laminated light steel keel sandwich insulation wall panel and an installation method thereof to solve the problems existing in the prior art. By setting the spring, a semi-rigid connection is made between the concrete slabs on both sides, which can effectively improve the bending resistance and stability of the system. After the insulation material is filled inside, the insulation stability and consistency are high, which can effectively improve the insulation effect.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to Figure 1 to Figure 11As shown, a hollow laminated light steel keel sandwich insulation wall panel is provided, including 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 concrete slabs 1 on both sides 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 concrete slabs 1 on both sides are connected by the light steel keel 2, and a filling space for filling insulation material 3 is formed between the concrete slabs 1 on both sides and the light steel keels 2 at both ends, and the insulation material 3 can be filled into the filling space by pouring; the two concrete slabs 1 in the present application are semi-rigidly connected by the spring 45 in the limiting mechanism 4 and the light steel keels 2 at both ends, which improves the bending resistance of the system and, when subjected to external force, the spring The spring 45 can provide moderate deformation and energy absorption, improve the seismic resistance and durability of the hollow laminated light steel keel sandwich insulation wall panel, effectively prevent the displacement or dislocation of the concrete slab 1, ensure the stability of the hollow laminated light steel keel sandwich insulation wall panel, and help improve the installation accuracy; in addition, the spring 45 is in the original length state at the beginning and combined with the concrete slab 1. In the early stage of the cast-in-place insulation material 3, the spring 45 is elongated due to the hydration heat to provide pressure for the system to resist the micro-expansion of the cast-in-place insulation material 3. The cast-in-place insulation material 3 shrinks in the later stage, so that the spring 45 is compressed to provide thrust for the system to alleviate the cracks generated in the later stage of the cast-in-place insulation material 3, thereby ensuring the stability and consistency of the insulation effect. When the insulation material 3 is poured, the fluidity of the insulation material 3 enables it to be fully filled, so that the insulation material 3 is in close contact with each component, thereby improving the insulation effect of the hollow laminated light steel keel sandwich insulation wall panel.

[0023] The first limiting member and the second limiting member may be fixedly arranged on the concrete slab 1 , or may be detachably arranged on the concrete slab 1 .

[0024] In this embodiment, a first limiting member and a second limiting member are selected to be detachably arranged on the concrete slab 1, and 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, and 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, and 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, and the second limiting rod 46 is fixedly arranged on the first limiting rod 42, and the first through hole 111 is provided on the concrete slab 1. The plate 47 is fixedly arranged on the second limiting rod 46, and 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 piece. The distance between the second connecting piece and the second limiting plate 47 is the same as the thickness of the concrete slab 1. The connection principle of the first limiting piece and the second limiting piece is the same, and both are achieved by limiting the two sides of the connecting piece and the limiting plate 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 piece and between the second limiting rod 46 and the second connecting piece can be selected by snap connection or threaded connection.

[0025] When the limiting rod is snap-connected with the connecting member, the first connecting member is the first push cover 41, the first limiting rod 42 is provided with a first fixing protrusion 421 at the end close to the first push cover 41, a first fixing groove 422 is provided between the first fixing protrusion 421 and the first limiting rod 42, the first push cover 41 is provided with a first reserved groove 411 matching the first fixing protrusion 421 and the first fixing groove 422, the first push 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 the second push cover 48, the second A second fixing protrusion 462 is provided at the end of the limiting rod 46 close to the second push cover 48, a second fixing groove 463 is provided between the second fixing protrusion 462 and the second limiting rod 46, and a second reserved groove 481 matching the second fixing protrusion 462 and the second fixing groove 463 is provided on the second push cover 48, and the second push cover 48 is buckled on the second fixing protrusion 462 and the second fixing groove 463 through the second reserved groove 481; the push cover itself has a deformation self-recovery function, and when actually connected, it can be buckled on the fixing protrusion and the fixing groove by pressing the push cover.

[0026] 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 can improve the structural strength.

[0027] 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, so that when processing the fixing protrusion and the fixing groove, the fixing groove can be directly opened on the rod to automatically form the fixing protrusion.

[0028] In this embodiment, the first limiting rod 42 and the second limiting rod 46 are both cylindrical structures.

[0029] The outer side surfaces of the first fixing protrusion 421 and the second fixing protrusion 462 can be configured as arc surfaces to facilitate buckling with the push cover.

[0030] The outer side surfaces of the first push cover 41 and the second push cover 48 can be configured as arc surfaces, so as to improve the convenience of press-fitting with the fixing protrusions.

[0031] When the limiting rod is threadedly connected to the connecting piece, the first connecting piece and the second connecting piece are replaced with screw covers with internal threads, and external threads are set on the first limiting rod 42 and the second limiting rod 46. After the screw covers are threadedly connected to the limiting rods, they cooperate with the limiting plates to achieve positioning connection.

[0032] In this embodiment, a sliding groove 44 is provided on the first limiting rod 42, and the sliding groove 44 matches the second limiting rod 46. The second limiting rod 46 is slidably arranged in the sliding groove 44, and a spring 45 is arranged in the sliding groove 44. One end of the spring 45 is connected to the groove 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 setting of the sliding groove 44 limits the radial movement of the spring 45, ensuring that the spring 45 can normally expand and contract to provide axial force for the concrete slabs 1 on both sides.

[0033] The concrete slabs 1 on both sides can be connected by a plurality of limiting mechanisms 4, and the plurality of limiting mechanisms 4 can be evenly distributed, so as to further improve the stability and bending resistance of the overall hollow laminated light steel keel sandwich insulation wall panel.

[0034] In this embodiment, the light steel keel 2 includes an integrally arranged first positioning plate 21, a second positioning plate 22, a third positioning plate 23 and a fourth positioning plate 24. 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 first positioning plates 21 at both ends are arranged in parallel, the second positioning plates 22 at both ends are located on the same plane, and the third positioning plates 23 at both ends are arranged in parallel. The first positioning plate 21 is connected to the concrete slab 1, and the end face of the concrete slab 1 is contacted with the second positioning plate 22 to produce a skin effect, thereby improving its overall performance. This design allows adjacent hollow overlapping light steel keel sandwich insulation wall panels to be installed conveniently and accurately, thereby improving construction efficiency and construction accuracy.

[0035] When a single hollow laminated light steel keel sandwich insulation wall panel is installed on site or pre-assembled in the factory, first pass the first limit rod 42 and the second limit rod 46 of the limit mechanism 4 through the concrete slabs 1 on both sides and connect the first push cover 41 and the second push cover 48, and 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 through a self-tapping screw B11. After the connection is completed, pour the insulation material 3 in the filling space. The insulation material 3 can be the insulation material 3 proposed in CN118930161A and CN117567118A or other applicable insulation material 3.

[0036] The present invention also provides an installation scheme for the above-mentioned hollow laminated light steel keel sandwich insulation wall panel, comprising the following steps: S1: two hollow laminated light steel keel sandwich insulation wall panels are arranged at intervals in the same plane, and the fourth positioning plates 24 of the two hollow laminated light steel keel sandwich insulation wall panels are arranged oppositely; S2: Determine whether another hollow laminated light steel keel sandwich insulation wall panel needs to be vertically installed between the two arranged hollow laminated light steel keel sandwich insulation wall panels according to the demand. If not, install the connecting plate 13 between the second positioning plates 22 of the two hollow laminated light steel keel sandwich insulation wall panels, connect the connecting plate 13 with the third positioning plate 23, and fill the filling space of the two hollow laminated light steel keel sandwich insulation wall panels with insulation material 3 after the connection is completed; if necessary, take another hollow laminated light steel keel sandwich insulation wall panel for installation; S3: Take another hollow laminated light steel keel sandwich insulation wall panel, insert the fourth positioning plate 24 of the light steel keel 2 of the hollow laminated light steel keel sandwich insulation wall panel between the two arranged hollow laminated light steel keel sandwich insulation wall panels, and connect them, and complete the assembly of the concrete plate 1, light steel keel 2 and limiting mechanism 4 of the hollow laminated light steel keel sandwich insulation wall panel. After the assembly is completed, fill the insulation material 3 in the filling space of the hollow laminated light steel keel sandwich insulation wall panel; S4: Fill the space between the hollow laminated light steel keel sandwich insulation wall panels with insulation material 3.

[0037] The connecting plate 13 in step S3 may also be a concrete plate 1 .

[0038] For example, in the case of assembling two-sided hollow laminated light steel keel sandwich insulation wall panels: for one side of the hollow laminated light steel keel sandwich insulation wall panel that has been cured, the 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 and the connecting plates 13 are fixed by self-tapping screws 3B23; the second positioning plates 22 and the third positioning plates 23 of the light steel keel 2 on one side of the hollow laminated light steel keel sandwich insulation wall panel that has been cured on the other side are fixed by self-tapping screws 3B23. 23 is inserted between the two connecting plates 13, and the connecting plate 13 and the light steel keel 2 are fixed by self-tapping screws B23; finally, the insulation material 3 is poured into the filling space of the two hollow overlapping light steel keel sandwich insulation wall panels and the interval space between the two hollow overlapping light steel keel sandwich insulation wall panels and the two connecting plates 13, and the first positioning plate 21 of each hollow overlapping light steel keel sandwich insulation wall panel is connected to the concrete slab 1 by self-tapping screws B21.

[0039] In the case of assembling three-sided hollow laminated light steel keel sandwich insulation wall panels: the difference from the assembly method of two-sided hollow laminated light steel keel sandwich insulation wall panels is that one side connecting plate 13 is replaced with a hollow laminated light steel keel sandwich insulation wall panel.

[0040] The specific assembly method is as follows: Place the connecting plate 13 on the outer side of the second positioning plate 22 and the third positioning plate 23 at one end of the light steel keel 2 on one side of the cured hollow laminated light steel keel sandwich insulation wall panel, and fix the light steel keel 2 and the connecting plate 13 by self-tapping screws 5 B33; Place the outer side of the second positioning plate 22 and the third positioning plate 23 of the light steel keel 2 on one side of the cured hollow laminated light steel keel sandwich insulation wall panel close to the end of the connecting plate 13, and fix the connecting plate 13 by self-tapping screws 5 B33 The connecting plate 13 is fixed to the light steel keel 2. At this time, the interval between the fourth positioning plates 24 of the two hollow laminated light steel keel sandwich insulation wall panels is equal to the width of the fourth positioning plate 24. Take another hollow laminated light steel keel sandwich insulation wall panel, and insert the fourth positioning plate 24 of the light steel keel 2 of the hollow laminated light steel keel sandwich insulation wall panel between the two arranged hollow laminated light steel keel sandwich insulation wall panels. At this time, the third positioning plate 23 of the hollow laminated light steel keel sandwich insulation wall panel is close to the remaining hollow laminated light steel keel sandwich insulation wall panels. The fourth positioning plate 24 of the steel keel sandwich insulation wall panel, the second positioning plate 22 of the hollow laminated light steel keel sandwich insulation wall panel is close to the third positioning plate 23 of the remaining hollow laminated light steel keel sandwich insulation wall panels, the first positioning plate 21 of the hollow laminated light steel keel sandwich insulation wall panel is close to the second positioning plate 22 of the remaining hollow laminated light steel keel sandwich insulation wall panels, and the third positioning plate 23 of the hollow laminated light steel keel sandwich insulation wall panel is connected to the remaining hollow laminated light steel keel sandwich insulation wall panels by self-tapping screws 6 B34. The fourth positioning plate 24 of the insulation wall panel is fixed, and finally the concrete plate 1, light steel keel 2 and limiting mechanism 4 of the hollow laminated light steel keel sandwich insulation wall panel are assembled. After the assembly is completed, the insulation material 3 is filled in the filling space of the hollow laminated light steel keel sandwich insulation wall panel and in the interval space between the three hollow laminated light steel keel sandwich insulation wall panels and the connecting plate 13. The first positioning plate 21 of each hollow laminated light steel keel sandwich insulation wall panel is connected to the concrete plate 1 by a self-tapping screw four B31.

[0041] In the case of assembling the four-sided hollow laminated light steel keel sandwich insulation wall panel: the difference from the assembly method of the three-sided hollow laminated light steel keel sandwich insulation wall panel is that the connecting plate 13 is replaced with the hollow laminated light steel keel sandwich insulation wall panel. The replacement method is the same as the method of replacing the connecting plate 13 of the hollow laminated light steel keel sandwich insulation wall panel in the assembly method of the three-sided hollow laminated light steel keel sandwich insulation wall panel. The hollow laminated light steel keel sandwich insulation wall panel used to replace the connecting plate 13 is firstly screwed with self-tapping screws 7B 44 connects the third positioning plate 23 of the light steel keel 2 with the fourth positioning plate 24 of the hollow overlapping light steel keel sandwich insulation wall panels on both sides. After the connection is completed, assemble the concrete plate 1, light steel keel 2 and limiting mechanism 4 of the hollow overlapping light steel keel sandwich insulation wall panels that replace the connecting plate 13. After the overall assembly is completed, fill the insulation material 3 in the filling space of the hollow overlapping light steel keel sandwich insulation wall panels and in the interval space between the four hollow overlapping light steel keel sandwich insulation wall panels and the connecting plate 13.
