[0017] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. Without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the scope of protection of the present utility model.

[0018] Figure 1 Figure 1 shows an embodiment of the structural column structure 2 of a self-insulating wall 1 of the present utility model. Refer to Figure 1 , in this embodiment, the structural column structure 2 of the self-insulating wall 1 includes: a wall 1 provided with a cutting seam 11, and the following is provided on the

[0019] Among them, refer to Figure 2 , the structural column structure 2 is successively provided with a concrete column 21 and a thermal insulation layer 22 in the direction extending from the inside to the outside of the cutting seam 11. The thermal insulation layer 22 is provided with at least one round hole 221 penetrating through its two end faces. Each round hole 221 penetrates a pin 23. The head of each pin 23 extends into the concrete column 21, and the top cap of each pin 23 remains on the side of the thermal insulation layer 22 away from the concrete column 21, so as to limit the thermal insulation layer 22 on the concrete column 21 and insulate the concrete column 21, so that the structural column structure 2 of the self-insulating wall 1 has both thermal insulation performance and avoids the occurrence of a heat (cold) bridge phenomenon between the self-insulating wall 1 and the structural column.

[0020] Optionally, the thermal insulation layer 22 is a rock wool board. The rock wool board is an inorganic fiber board formed by high-temperature melting, with a low thermal conductivity and excellent thermal insulation effect, and has an excellent thermal insulation effect on the outer surface of the structural column.

[0021] Furthermore, refer to Figure 2 , the structural column structure 2 further includes a leveling layer 24. The leveling layer 24 is coated on the side of the thermal insulation layer 22 away from the concrete column 21, so that the end face of the structural column structure 2 exposed from the cutting seam 11 is flush with the outer surface of the wall 1.

[0022] Furthermore, refer to Figure 2 , the leveling layer 24 is provided with a mesh cloth 241 respectively connected to each pin 23 to prevent the leveling layer 24 from detaching from the thermal insulation layer 22 or cracking.

[0023] Optionally, the leveling layer 24 is a mixture of cement and mortar prepared in a certain proportion. Since the cement mortar is directly coated on the surface of the rock wool board and is prone to falling off and cracking, a mesh cloth 241 is fixed on the surface of the rock wool board, and then the cement mortar is coated, so that the solidified cement mortar is not easy to crack or separate from the rock wool board.

[0024] Optionally, the mesh cloth 241 is made of alkali-resistant fiberglass or alkali-resistant steel wire mesh. When the wall plastering thickness is less than 35 mm, the mesh cloth 241 made of alkali-resistant fiberglass is used. When the wall plastering thickness is greater than 35 mm, the mesh cloth 241 made of alkali-resistant steel wire is used.

[0025] Further, referring to Figure 2 , the structural column structure 2 further includes a decorative layer 25 coated on the side of the leveling layer 24 away from the insulation layer 22, so that the end face of the structural column structure 2 exposing the cutting seam 11 is consistent with the outer facade of the wall 1.

[0026] Optionally, the decorative layer 25 is wall paint or wall tiles.

[0027] In this embodiment, the insulation layer 22 is pasted on one side of the concrete column 21 adjacent to the outer facade of the wall 1 and fixed by dowel pins 23 to insulate the concrete column 21, so that the structural column structure 2 of the self-insulating wall 1 has heat insulation performance and avoids the occurrence of heat (cold) bridge phenomena between the self-insulating wall 1 and the structural column.

[0028] In order to increase the stability of the connection between the structural column structure 2 and the wall 1, on the basis of the above embodiment, referring to Figure 1 , the structural column structure 2 further includes implanted bars 26 and tie bars 27.

[0029] Among them, referring to Figure 1 , at least one implanted bar 26 stands upright inside the concrete column 21, and at least one tie bar 27 is arranged radially along the concrete column 21. Each tie bar 27 is horizontally arranged and penetrates through the concrete column 21, and both ends in the length direction extend into the wall 1. Each tie bar 27 is respectively connected to each implanted bar 26 by a binding band to increase the connection strength between the structural column structure 2 and the wall 1.

[0030] Optionally, the tie bars 27 are embedded in the wall 1 and partially exposed in the cutting seam 11. The implanted bars 26 stand in the cutting seam 11 and are connected to the tie bars 27 by binding bands such as steel wires. During concrete pouring, the implanted bars 26 and the tie bars 27 are directly embedded inside the concrete column 21.

[0031] Further, referring to Figure 1, chamfers of the first toothing are provided on two inner walls of the cutting seams 11 that are close to each other, and chamfers of the second toothing that match each of the first toothing chamfers are provided on the concrete column 21. Each of the first toothing chamfers is respectively clamped to each of the second toothing chamfers to increase the connection strength between the structural column structure 2 and the wall 1.

[0032] Optionally, the chamfers of the first toothing are cut by a cutting tool, and the chamfers of the second toothing are generated during the pouring process of the concrete column 21 and are clamped to the chamfers of the first toothing as the concrete solidifies.

[0033] For example, the construction steps of the structural column structure 2 of the self-insulating wall 1 are as follows:

[0034] (1) Conduct on-site surveys before measuring and setting out the lines, measure the dimensions of the structural column, the size of the mortar joint, the thickness of the outer wall, the distance between the chamfers of the first toothing, etc.; check the drawings and specifications, and analyze the treatment methods for the external wall insulation, including possible phenomena such as concrete cracking and ineffective formwork erection.

[0035] (2) After setting up the mortar joint rod, use a laser level to pop out the control line for the chamfers of the first toothing, and make the entire laser line consistent with the block size and the width of the mortar joint. At the same time, accurately control the verticality and flatness of the wall 1.

[0036] (3) Pop out the control line according to the laser level and accurately calculate the block size, and use an autoclaved aerated concrete block cutting machine for cutting.

[0037] (4) After the block cutting is completed, use polymer mortar to enhance the adhesion between autoclaved aerated concrete blocks. The polymer mortar has a small thermal conductivity and effectively prevents the formation of heat (cold) bridges in the mortar joints of the masonry.

[0038] (5) After the masonry is completed, cut the blocks on both sides along the length direction of the structural column wall to a width of 110 mm (including a total width of 420 mm for the structural column), a thickness of 50 mm, and flush with the structural column. During the later external wall insulation construction, thermal bridge parts are treated with insulation; and the upper part of the toothing is cut into a 45-degree bevel, effectively solving quality problems such as mortar leakage and cracking during the on-site concrete structural column pouring construction, and enhancing the connection stability between the wall 1 and the structural column. During the cutting process, a laser level is used to ensure that the cutting seams 11 on both sides of the structural column are on the same horizontal line.

[0039] (6) After the masonry construction is completed, set up the formwork for the structural column along the cutting seams 11 on both sides of the structural column to ensure effective formwork erection.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
