The wire mesh composite insulation board is placed between the outer formwork and the inner formwork, and is further connected to the outer formwork and the inner formwork, so that concrete can be poured in the cavity formed between the wire mesh composite insulation board and the inner and outer formworks. After the concrete solidifies, the wire mesh composite insulation board and the concrete are formed into one, which has the advantages of firm fixation, long service life, and short construction period.

DETAILED DESCRIPTION

[0054] In order to clearly illustrate the technical features of the present solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0055] It should be noted that many specific details are described in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0056] like Figure 1-Figure 3 As shown in, on the one hand, the present invention provides a positioning support member, including a support member body 100 and a first positioning member 200 and a second positioning member 300 installed on the support member body 100, the support member body 100 extends in a straight line between the first end and the second end, the first positioning member 200 and the second positioning member 300 are respectively arranged near the first end and the second end of the support member body 100, and the second positioning member 300 is interconnected with the support member body 100 through a positioning mechanism to at least limit the second positioning member 300 from moving toward the first positioning member 200.

[0057] The inner end surfaces of the first positioning member 200 and the second positioning member 300 respectively constitute the heat preservation board abutment portion 220 , and the outer end surface of the first positioning member 200 is provided with a wire mesh supporting portion 210 .

[0058] The support body 100 is provided with a first steel mesh card slot 110, which penetrates the second end face of the support body 100 and extends to the first end over the connection position of the first positioning member 200 on the support body 100, and the first steel mesh card slot 110 is used to insert the horizontal wire or vertical wire of the steel mesh 510. The positions of the horizontal wire and the vertical wire of the steel mesh 510 are relative, and their names can be adjusted according to the arrangement orientation during the construction process. For the convenience of description, in the drawings of the present invention, the length direction of the slot 240 is taken as the vertical direction, the steel wire parallel to the direction is the vertical wire, and the steel wire perpendicular to the direction is the horizontal wire, and each square is surrounded by 2 sections of horizontal wire and 2 sections of vertical wire.

[0059] When in use, a certain section of the horizontal wire of the steel mesh 510 is supported on the steel mesh supporting portion 210 on the first positioning member 200, and the entrance of the first steel mesh slot 110 on the support member body 100 is aligned with the horizontal wire or another horizontal wire or vertical wire, and then the support member body 100 is moved forward so that the second end of the support member body 100 passes through the first positioning member 200 and the insulation board 520. The horizontal wire or vertical wire will gradually enter the bottom of the first steel mesh slot 110 as the support member body 100 moves, and at this time, the insulation board abutment portion 220 of the first positioning member 200 will also abut against the surface of the insulation board 520, and then the second positioning member 300 is installed on the support member body 100, so that the insulation board abutment portion 220 of the second positioning member 300 abuts against the insulation board 520, and the steel mesh 510 can be connected to the insulation board 520 to form (such as Fig.14 Composite structure of steel wire mesh and insulation board (as shown).

[0060] In the composite structure of the steel mesh and the insulation board, the second positioning member 300 cannot move toward the second end of the support body 100 under the constraint of the positioning mechanism, so the insulation board 520 and the first positioning member 200 cannot move toward the second end of the support body 100, and the steel mesh supporting portion 210 on the first positioning member 200 cannot move toward the second end of the support body 100, and a certain horizontal wire of the steel mesh 510 is stuck in the bottom of the first steel mesh slot 110, so the steel mesh 510 cannot move toward the first end of the support body 100. In this way, under the constraint of the steel mesh 510, the first positioning member 200 cannot move toward the first end of the support body 100, the steel mesh 510 is restricted between the first steel mesh slot 110 and the steel mesh supporting portion 210, and the insulation board 520 is restricted between the first positioning member 200 and the second positioning member 300.

[0061] The support member body 100 is a long plate structure with a certain thickness. It is most convenient to assemble the first positioning member 200 and the second positioning member 300 with the support member body 100 by sleeve connection, and the connection area is also large. Specifically, the first positioning member 200 and the second positioning member 300 are respectively provided with slots 240, and the slots 240 penetrate the inner and outer end surfaces of the first positioning member 200 and the second positioning member 300 along the extension direction of the support member body 100. The cross section of the slots 240 matches the cross section of the support member body 100, and the slots 240 are used for the support member body 100 to pass through. In one specific embodiment, the positioning mechanism includes a positioning hole 121 provided on the support member body 100 and a positioning pin 122 passing through the positioning hole 121, and the positioning hole 121 is close to the insulation board abutment portion 220 on the second positioning member 300.

[0062] In the conventional positioning support, the surface of the insulation board abutment part 220 in contact with the insulation board 520 is a plane. Since there is no direct connection between the insulation board abutment part 220 and the insulation board 520, the vibration of the composite structure of the wire mesh and the insulation board will cause the hole of the positioning support to be inserted into the insulation board 520 to deform and expand, causing the positioning support to tilt and lose effective positioning with the insulation board 520. In order to solve this problem, in a preferred embodiment, the insulation board plug-in part 230 is provided on the inner end faces opposite to the first positioning member 200 and the second positioning member 300, and the insulation board plug-in part 230 is used to be inserted into the insulation board 520. Furthermore, the insulation board plug-in part 230 is composed of a plurality of insert teeth extending in the same direction as the support body 100, and the insert teeth are distributed in an array, which is more conducive to inserting into the insulation board 520.

[0063] The positioning support provided by the present invention is mainly used for the external insulation construction of the shear wall, so the second end of the support body 100 is located in the concrete body. In order to improve the connection strength between the second end of the support body 100 and the concrete body, as shown in FIG. Figure 3 As shown in , in a preferred embodiment, a concrete connection part 130 is provided at the second end of the support body 100. Generally, the concrete connection part 130 can be specifically provided in the form of a tooth groove or a binding hole at the second end of the support body 100, the tooth groove can improve the tensile strength of the support body 100, and the binding hole can be used for binding with the steel bar frame in the concrete body.

[0064] In order to facilitate the horizontal wires or vertical wires of the steel mesh 510 to enter the first steel mesh slot 110, the entrance of the first steel mesh slot 110 is preferably configured to be trumpet-shaped.

[0065] Based on the above structure, the structure of the wire mesh supporting portion 210 in the positioning support member provided in the present application will be illustrated below through specific embodiments.

[0066] Embodiment 1:

[0067] In this embodiment, the wire mesh supporting portion 210 includes a plurality of support seats 410 disposed on the outer end surface of the first positioning member 200 , and the support seats 410 avoid the position of the slots 240 on the first positioning member 200 .

[0068] Specifically, Figure 2 As shown in FIG. 1 , the number of the support seats 410 can be two, and the two support seats 410 are respectively located on the left and right sides of the length direction of the slot 240, so that a certain section of the horizontal wire can be supported by the two support seats 410 at the same time (such as Figure 4 ), or two support seats 410 respectively support two adjacent horizontal wires on the left and right (as shown in Figure 5 ).

[0069] After the horizontal wires of the wire mesh 510 are supported on the wire mesh supporting part 210, in order to further prevent the horizontal wires from moving, it is preferably provided with a second wire mesh slot 211 at the outer end of the wire mesh supporting part 210, and the second wire mesh slot 211 penetrates the outer end face of the wire mesh supporting part 210, and the extension direction of the second wire mesh slot 211 is perpendicular to the length direction of the slot 240, and a certain section of the horizontal wire of the wire mesh 510 can be inserted into the second wire mesh slot 211 to constrain its position on the wire mesh supporting part 210.

[0070] In order to improve the strength of the support seat 410 and prevent the support seat 410 from being broken due to excessive external force during transportation or construction, in this embodiment, the support seat 410 is configured as a wedge-shaped structure, and the thicker end of the wedge-shaped structure is connected to the outer end face of the first positioning member 200.

[0071] Embodiment 2:

[0072] The difference between this embodiment and the first embodiment is that, in this embodiment, the two support seats 410 are respectively located at the upper and lower sides of the slot 240 in the length direction or at the same side in the length direction.

[0073] like Figure 5 and Figure 7 As shown in the figure, the two support seats 410 can respectively support two horizontal wires spaced apart from each other, and the horizontal wire between the two horizontal wires is inserted into the first steel wire mesh slot 110, so as to prevent the steel wire mesh 510 from moving up and down or left and right.

[0074] like Figure 8 As shown in , the two support seats 410 can respectively support two adjacent vertical wires, and the horizontal wires vertically connected to the two vertical wires are inserted into the first steel wire mesh slot 110.

[0075] Embodiment 3:

[0076] like Fig. 9 As shown in , the difference between this embodiment and embodiment 1 is that, in this embodiment, the support seat 410 adopts a plate-like structure, and its side surface is connected to the outer end surface of the first positioning member 200 through a plurality of reinforcing ribs 411, and the reinforcing ribs 411 can share the force of the support seat 410.

[0077] Embodiment 4:

[0078] like Fig.10 As shown in , in this embodiment, the wire mesh supporting portion 210 includes a boss 420 arranged on the outer end surface of the first positioning member 200, and the slot 240 on the first positioning member 200 passes through the boss 420, and the boss 420 is a solid or hollow structure.

[0079] A second steel mesh slot 211 is disposed at the outer end of the boss 420 . The second steel mesh slot 211 passes through the outer end surface of the boss 420 . The extension direction of the second steel mesh slot 211 is perpendicular to the length direction of the slot 240 .

[0080] When the boss 420 is a cylindrical hollow structure, the material cost can be reduced, and the second wire mesh slot 211 can be opened on the side wall of the cylindrical structure. In order to improve the strength of the cylindrical structure, it is preferred to set a reinforcing rib 411 on the outer side of the cylindrical structure.

[0081] Embodiment 5:

[0082] like Fig.11 As shown in, in this embodiment, the wire mesh supporting portion 210 includes a support plate 430 arranged parallel to the outer end surface of the first positioning member 200, the support plate 430 is connected to the outer end surface of the first positioning member 200 through a plurality of connecting plates 431, the slot 240 on the first positioning member 200 passes through the support plate 430, the support plate 430 avoids the position of the slot 240, and the surface of the support plate 430 constitutes the wire mesh supporting portion 210.

[0083] Embodiment 6:

[0084] like Fig.12 As shown in , in this embodiment, the wire mesh support part 210 includes a partition 440 arranged along the mid-vertical line of the slot 240, and the outer end of the partition 440 is provided with a second wire mesh card slot 211, and the second wire mesh card slot 211 passes through the outer end surface of the partition 440. The middle part of the partition 440 facing the slot 240 is thinner and is not greater than the width of the first wire mesh card slot 110, so as to ensure that the support body 100 can ride on the middle part of the partition 440 and pass through the slot 240. In this embodiment, the same section of the horizontal wire or vertical wire of the wire mesh 510 is simultaneously limited by the wire mesh support part 210 and the first wire mesh card slot 110. In order to improve the strength of the partition 440, the partition 440 preferably adopts a wedge structure.

[0085] In the above-mentioned embodiments 1-4, the bottom of the second steel mesh slot 211 is preferably provided with an arc-shaped expansion portion 212, and the diameter of the arc-shaped expansion portion 212 is equal to the diameter of the horizontal wire or vertical wire of the steel mesh 510. The horizontal wire or vertical wire of the steel mesh 510 squeezes open the entrance section of the second steel mesh slot 211 and falls into the arc-shaped expansion portion 212 at the bottom of the slot, thereby preventing the horizontal wire or vertical wire of the steel mesh 510 from escaping from the second steel mesh slot 211.

[0086] like Fig.13As shown in , in another embodiment, the bottom of the first steel mesh slot 110 is connected to a locking slot 111, and the locking slot 111 is located on one side of the length direction of the first steel mesh slot 110. The horizontal wire or vertical wire of the steel mesh 510 falls into the locking slot 111 from the bottom of the first steel mesh slot 110, so that the force of the steel mesh 510 along the extension direction of the support body 100 can act on the locking slot 111. In this embodiment, when assembling the steel mesh 510 and the insulation board 520, it is necessary to first insert a section of the horizontal wire of the steel mesh 510 into the first steel mesh slot 110 on the first support member body 100, and then pass the support member body 100 through the first positioning member 200 and the insulation board 520. In the process of passing through the first positioning member 200 and the insulation board 520, the section of the horizontal wire gradually approaches the steel mesh supporting portion 210 and finally rests on the steel mesh supporting portion 210.

[0087] like Fig.14 As shown in , on the other hand, the present invention also provides a composite structure of a steel mesh and a heat preservation board, including a steel mesh 510 and a heat preservation board 520, and also including the positioning support member, the support member body 100 passes through the heat preservation board 520, and the heat preservation board abutting portions 220 on the first positioning member 200 and the second positioning member 300 respectively abut against the two sides of the heat preservation board 520;

[0088] The horizontal wires or vertical wires of the steel mesh 510 are inserted into the first steel mesh slots 110 on the support body 100 and / or supported on the steel mesh supporting portion 210 of the first positioning member 200 .

[0089] In another aspect, the present invention further provides a method for connecting a steel mesh sheet to an insulation board, using the positioning support member described in Embodiments 1 to 4, and comprising the following steps:

[0090] (1) The first positioning members 200 are evenly installed on the steel mesh 510, so that the horizontal wires of the steel mesh 510 are inserted into the second steel mesh card slots 211 on the steel mesh support portion 210. About 6 positioning support members are required per square meter, so about 6 first positioning members 200 are pre-arranged on each square meter of the steel mesh 510;

[0091] (2) Laminating the steel mesh sheet 510 with the first positioning member 200 installed on the insulation board 520, with the insulation board plug-in portion 230 facing the insulation board 520;

[0092] (3) Press the first positioning member 200 to insert the insulation board plug-in portion 230 into the insulation board 520;

[0093] (4) Align the entrance of the first steel mesh slot 110 on the support body 100 with the horizontal wire of the steel mesh 510 that has been inserted into the second steel mesh slot 211, push the support body 100, and make the second end of the support body 100 pass through the first positioning member 200 and the insulation board 520 in sequence, so that the horizontal wire of the steel mesh 510 is inserted into the bottom of the first steel mesh slot 110;

[0094] (5) The second positioning member 300 is mounted on the second end of the support member body 100, so that the second positioning member 300 is connected to the support member body 100 through the positioning mechanism.

[0095] like Fig.15 As shown in , when the positioning support member provided by Example 1 is used, the two wire mesh supporting parts 210 on the first positioning member 200 respectively support two adjacent horizontal wires on both sides of the same vertical wire of the wire mesh 510, and one of the wire mesh supporting parts 210 also rests on the vertical wire at the same time, thereby avoiding relative displacement of the wire mesh 510 and the support member body 100 in the up, down, left and right directions.
