[0037] Embodiment one

[0038] As shown in 1 to Figure 6 The utility model discloses a kind of light sandwich thermal insulation wall structures, it includes two groups of symmetrical distribution profile board 2, profile board 2 has several groups of inner recess 21, core board 1 is arranged between two profile boards 2, core board 1 selects insulation board, the inner recess 21 of corresponding profile board 2 is attached on the two sides of core board 1 respectively, and forms sandwich profile;Several groups of perforations are set on inner recess 21 position and core board 1, positioning rod 5 is penetrated through sandwich profile by perforation, and positioning rod 5 both ends are protruding from both sides of sandwich profile;Tightening piece 3 is respectively screw-connected on the both sides of positioning rod 5, when two tightening pieces 3 are screw-connected, it is synchronously moved inward along positioning rod 5, generates clamping force, to be used for clamping and fixing profile board 2 and core board 1 inside positioning piece;It also includes connecting piece 4 and steel wire net rack 6, connecting piece 4 is detachably arranged at the outer end of tightening piece 3, for connecting steel wire net rack 6 located at both sides of sandwich profile, steel wire net rack 6 is positioned at both sides of sandwich profile with interval, to avoid its displacement when subsequent pouring;Sand mortar is poured on both sides of sandwich profile, sand mortar is over steel wire net rack 6, and forms light sandwich thermal insulation wall structure.

[0039] The utility model constructs a kind of sandwich thermal insulation wall structure, by placing core board 1 in cavity structure inside, not only retain the original cavity structure, let cavity form air layer, effectively block heat conduction, achieve the effect of efficient thermal insulation, and the design of core board 1 makes wall body possess double thermal barrier, further inhibit heat transfer, substantially improve thermal insulation performance.

[0040] In structural stability design, the utility model is positioned with positioning rod 5, so that it penetrates sandwich profile, and two top tight pieces 3 are used to clamp profile plate 2, so that two profile plates 2 and the core board 1 in the middle are tightly combined as a whole, and the load strength of the wall body is significantly enhanced.In addition, the utility model makes full use of top tight piece 3, connects connecting piece 4 on top tight piece 3, and positions steel wire mesh frame 6 arranged on both sides of the wall body through the connecting piece 4. With this design, the stability of steel wire mesh frame 6 is guaranteed during the pouring of mortar, effectively avoiding displacement problems, and improving construction quality and overall performance of the wall body.

[0041] In some embodiments, connecting piece 4 includes connecting plate 41 detachably connected to top tight piece 3, one end of connecting plate 41 is fixed with hooks 42 symmetrically distributed, hooks 42 are inclined outward, used for hooking the connection points of horizontal ribs and vertical ribs in steel wire mesh frame 6. With the existing top tight piece 3, connecting plate 41 is installed, so that hooks 42 can hook steel wire mesh frame 6 and position it, to a certain extent, to avoid large displacement of steel wire mesh frame 6.

[0042] In some embodiments, one connecting piece 4 is installed on each top tight piece 3, and hooks 42 on connecting piece 4 are arranged downward to position steel wire mesh frame 6 in a towing manner. This fixing method has deficiencies in certain construction scenarios. For example, when building a formwork and pouring mortar, the top of steel wire mesh frame 6 lacks limiting, and under the action of mortar buoyancy, steel wire mesh frame 6 may float up.

[0043] To avoid this situation, in other embodiments, two groups of connecting pieces 4 are installed corresponding to each top tight piece 3, and are symmetrically distributed upward and downward. Four groups of hooks 42 are provided in the two groups of connecting pieces 4, and are arranged in a rectangular shape, and are respectively hooked on the connection points of horizontal ribs and vertical ribs of steel wire mesh frame 6, greatly improving the firmness of the positioning of steel wire mesh frame 6, and effectively avoiding the displacement and floating of steel wire mesh frame 6 during pouring.

[0044] Further, avoiding slot 43 is formed on connecting plate 41, allowing connecting plate 41 to move along avoiding slot 43 relative to positioning rod 5; a plurality of groups of through holes 44 are also formed on both sides of connecting plate 41, and two groups of bolts 45 located on both sides pass through through holes 44 and are screw-connected with threaded grooves in top tight piece 3, to fix connecting plate 41 to the outside of top tight piece 3.

[0045] When the steel wire mesh frame 6 needs to be positioned, the two connecting plates 41 can be moved to the center by means of the avoiding grooves 43. During the movement, the two lower hooks 42 gradually approach each other to generate a clamping force on the steel wire mesh frame 6, thereby achieving accurate positioning of the steel wire mesh frame 6. After positioning is completed, the through holes 44 on the two connecting pieces 4 accurately correspond to the threaded grooves on the tightening piece 3. At this time, the bolts 45 are passed through the through holes 44 of the two connecting plates 41 and are screwed into the threaded grooves, so that the two connecting pieces 4 can be firmly fixed on the tightening piece 3. Through the design, the steel wire mesh frame 6 can be stably positioned on one side of the sandwich profile, greatly improving the stability and reliability of the overall structure during the construction process.

[0046] In some embodiments, the tightening piece 3 includes a pressing ring 31, and the outer side of the pressing ring 31 is connected with a rotating ring 33 through a connecting part 32. The inner wall of the rotating ring 33 has an internal threaded section and is threadedly connected with the positioning rod 5. The connecting piece 4 described above can be detachably installed on the outer side of the rotating ring 33.

[0047] In actual application scenarios, the pressing ring 31 in the two tightening pieces 3 can effectively clamp the two profile plates 2, achieving fixation of the profile plates 2. The connection length can control the distance between the rotating ring 33 and the sandwich profile. In different construction projects, the connecting part 32 of the corresponding length can be customized according to the specific design requirements to meet the diversified construction needs. The rotating ring 33 serves as a driving component. During construction, the construction personnel rotates the rotating ring 33 to achieve axial feeding of the pressing ring 31 along the positioning rod 5 by means of the threaded transmission principle, thereby accurately controlling the clamping force on the profile plates 2.

[0048] Reference Figure 4 In some embodiments, the profile plate 2 has a plurality of groups of staggered distribution of the concave part 21 and the convex part 22. The inner wall of the concave part 21 is attached to the side surface of the core plate 1, and the inner wall of the convex part 22 is spaced apart from the core plate 1 to form a cavity. Through this design, the air layer is used to achieve the heat preservation effect; at the same time, the use amount of wall materials is greatly reduced to meet the demand of lightweight wall, effectively reducing the load caused by the self weight of the wall, especially for high-rise buildings.

[0049] Further, at least one group of inner grooves 23 is formed on the outer wall of the convex part 22. The design of the inner grooves 23 enables the slurry to flow into the inner grooves 23 during the subsequent pouring of the slurry, increases the contact area with the concrete, forms a "mechanical interlock", and makes the sandwich profile and the concrete become a collaborative force whole.
