In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set" and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] Reference Figure 1-4 The embodiment of the present invention provides a self-insulating composite wall spacer, which includes an anchoring portion 2, a distance controlling portion 1 and a connecting portion 3 for connecting the two; along the direction away from the connecting portion 3, the cross-sectional size of the anchoring portion 2 gradually decreases to facilitate anchoring in the insulation layer 6; the distance controlling portion 1 is used to control the distance between the insulation layer 6 and the steel grid 5, and is provided with a first card slot 4 and a first through hole 14, the first card slot 4 is located at the end thereof facing away from the connecting portion 3, and is used to clamp the steel grid 5, and the first through hole 14 is distributed in a plurality of groups on the distance controlling portion 1 for ventilation and slurry.

[0031] When using the above-mentioned self-insulating composite wall pads for construction, (1) according to the layout of the steel mesh frame 5 and the layout requirements of the insulation layer 6, mark several anchor points on the insulation layer 6; (2) insert the anchor part 2 in the self-insulating composite wall pad into the insulation layer 6 and anchor it at the anchor point; (3) after all the self-insulating composite wall pads are anchored and stably fixed to the insulation layer 6, lift the insulation layer 6 upright so that the distance control parts 1 of the self-insulating composite wall pads are all facing the steel mesh frame 5, and the self-insulating composite wall pads are all aligned with the insulation layer 6. The thermal insulation layer 6 is hoisted to the side of the steel mesh 5, and the steel bars in the steel mesh 5 are clamped in the first clamping groove 4 at the corresponding position; (4) concrete pouring is carried out. During the pouring process, a plurality of self-insulating composite wall pads cooperate to fix the thermal insulation layer 6 to reduce the disturbance of the concrete and avoid its displacement or tilting; during pouring, the gas at the bottom of the distance control part 1 can be discharged upward through the first through hole 14 to avoid the formation of a cavity, and the slurry above the distance control part 1 can fall downward through the first through hole 14 to improve the pouring density.

[0032] The transverse dimension of the distance control part 1 is fixed, which can ensure that the distance between the steel grid 5 and the insulation layer 6 on both sides is stable and accurate, thereby ensuring that the wall thickness on both sides of the steel grid 5 meets the construction requirements; the first clamping grooves 4 on each distance control part 1 respectively clamp the steel bars at different positions on the steel grid 5, and cooperate to stabilize the vertical height of the insulation layer 6 and the relative position of its large surface and the side of the steel grid 5, to ensure that the insulation effect of the wall meets the preset requirements.

[0033] Reference Figure 2-3The distance control part 1 includes a distance control axis 11 and a plurality of distance control pieces 12 circumferentially dispersed around the distance control axis 11, and a first through hole 14 penetrates the large surface of the distance control piece 12; a first half groove 13 is configured at the end of the distance control piece 12 facing away from the connection part 3, and a plurality of first half grooves 13 are assembled into a first card slot 4; the distance control piece 12 at least includes: a first bottom edge 121 facing the connection part 3, a first top edge 122 facing away from the connection part 3, and a first side edge 123 and a second side edge 124 for connecting the two, the first side edge 123 and the second side edge 124 are configured oppositely, and the first side edge 123 is connected to the distance control axis 11; the first half groove 13 has a first groove wall 131 and a second groove wall 132, the first groove wall 131 is recessed from the first top edge 122 to the first bottom edge 121, and the second groove wall 132 is recessed from the first side edge 123 to the second side edge 124, and the end surface of the distance control axis 11 facing away from the connection part 3 is flush with the first groove wall 131.

[0034] Several first half grooves 13 are connected to form a first slot 4 in a cross shape (4 first half grooves 13), a M shape (8 first half grooves 13) or other similar shapes, which corresponds to the intersection of the steel bars in the steel grid 5, so that the distance control part 1 is clamped at the intersection of the steel bars in the steel grid 5 to avoid displacement of the distance control part 1, thereby ensuring the position accuracy of the insulation layer 6.

[0035] Reference Figure 1-2 The anchoring part 2 includes an anchoring axis 21 and a plurality of anchoring sheets 22 circumferentially dispersed around the anchoring axis 21. The anchoring sheet 22 includes at least: a second bottom edge 221 facing the connection part 3, a third side edge 223 connected to the anchoring axis 21, and a fourth side edge 224 for connecting the two. In the direction away from the connection part 3, the distance between the fourth side edge 224 and the third side edge 223 gradually decreases. With the above-mentioned configuration of the anchoring sheet 22, the anchoring part 2 is tapered, and the tip is facing the insulation layer 6, which is easier to penetrate into the insulation layer 6. In addition, the large surface of the anchoring sheet 22 has a large contact area with the insulation layer 6, and the anchoring effect is good.

[0036] In some more preferred embodiments, the anchoring sheet 22 and the distance control sheet 12 can be configured in the same configuration, that is, the anchoring sheet 22 includes a second top edge 222 facing away from the connection portion 3, a second half groove 23 is configured on the second top edge 222, a plurality of second half grooves 23 are assembled into a second card slot, the second half groove 23 is configured in the same configuration as the first half groove 13, and the second card slot is configured in the same configuration as the first card slot 4; the anchoring sheet 22 is configured with a second through hole 24 that runs through its large surface; in the direction away from the connection portion 3, the spacing between the second side edge 124 and the first side edge 123 gradually decreases. In this way, the direction distinction between the anchoring portion 2 and the distance control portion 1 can be reduced during construction, the time-consuming time of changing the direction after taking the wrong position can be reduced, and the construction convenience and efficiency can be improved.

[0037] Reference Figure 1-2The connecting portion 3 includes a connecting shaft 31 and a plurality of connecting pieces 32 circumferentially dispersed around the connecting shaft 31.

In this way, the identification and replacement of the direction of the self-insulating composite wall pad during construction is further reduced. During installation, it is sufficient to ensure that one of the connecting piece 32, the anchoring piece 22 and the distance control piece 12 is parallel to the large surface of the insulation layer 6, which further improves the construction convenience and efficiency.

[0038] Optionally, the first through hole 14, the second through hole 24 and the third through hole 34 are independently selected from one or more of a polygonal hole, a circular hole, an elliptical hole and a special-shaped hole. Figure 1 Only one configuration, the triangular hole, is cited as an example, but it is not intended to limit the scope of protection of the present invention.

[0039] According to the staggered conditions and quantity of the steel meshes in different parts of the steel mesh frame 5 during construction, the number of the distance control pieces 12 distributed around the distance control axis 11, the number of the anchoring pieces 22 distributed around the anchoring axis 21, and the number of the connecting pieces 32 distributed around the connecting axis 31 can be selected by the user. Figure 1 The most commonly used configuration is listed only by way of example: the distance control axis 11 has 4 groups of distance control plates 12 distributed circumferentially, the anchor axis 21 has 4 groups of anchor plates 22 distributed circumferentially, the connecting axis 31 has 4 groups of connecting plates 32 distributed circumferentially, and two groups of connecting parts 3 are symmetrically distributed on both sides of the anchor axis 21, of which 2 groups of connecting plates 32 at the same position as the distance control plates 12 are constructed of sheets with a fusion configuration, which contains all the structural features of the connecting plates 32 and the distance control plates 12, and 2 groups of connecting plates 32 at the same position as the anchor plates 22 are also constructed of sheets with a fusion configuration, which contains all the structural features of the connecting plates 32 and the anchor plates 22.
