[0023] Example 1 This embodiment is applicable to the construction of frame formwork support for polygonal openings, such as pentagonal ones.

[0024] Please see Figure 1 This embodiment provides an adjustable top support for the opening frame template, which includes a support template 100, a first fastening mechanism 200, and a second fastening mechanism 300.

[0025] The number of supporting templates 100 is the same as the number of openings, and the shape of multiple supporting templates 100 connected to each other is adapted to the shape of the openings. Since the openings in this application are polygonal, when the template support construction is completed, all the supporting templates 100 are connected end to end to form a closed frame structure.

[0026] The connection point on the inner side of adjacent support templates 100 is defined as a connection node. A first fastening mechanism 200 is installed in one of the connection nodes, and multiple second fastening mechanisms 300 are installed in the remaining connection nodes, with one second fastening mechanism 300 installed in a corresponding connection node.

[0027] For ease of description and understanding, the accompanying drawings of this embodiment only provide illustrative examples of the first and last connecting nodes. The connecting node in the upper left corner is the first connecting node, and the connecting node in the lower left corner is the last connecting node, that is, the first support template 100, the second support template 100, and the last support template 100 are shown.

[0028] Please see Figure 2 and Figure 3 Each support template 100 includes a template body 110 and two extension members 120. The two extension members 120 are disposed at both ends of the template body 110. Each extension member 120 slides relative to the template body 110 along the length direction of the template body 110. Each extension member 120 is provided with a fixing block 124.

[0029] The sliding method described above is as follows: each support template 100 further includes a first sliding member 130 and two second sliding members 140. The two second sliding members 140 are respectively disposed at both ends of the first sliding member 130, and each second sliding member 140 slides relative to the first sliding member 130 along the length direction of the template body 110. The first sliding member 130 is fixed to the template body 110, and one second sliding member 140 is fixed to an extension member 120.

[0030] The cross-section of the first slider 130 is larger than the cross-section of the second slider 140, and the second slider 140 is inserted into the first slider 130.

[0031] In this embodiment, the first sliding member 130 and the second sliding member 140 can be set to be square tubes. Specifically, the first sliding member 130 is configured as anti-torsion square steel. The number of the first sliding members 130 is determined according to the actual support strength. For example, the wider the template body 110 is, the more first sliding members 130 are set. Multiple first sliding members 130 are spaced apart along the width direction of the template body 110.

[0032] In this embodiment, the template body 110 is a rectangular structure with a certain width and length. The extension 120 is set in the length direction to adjust the length of the support template 100, thereby adapting to openings with different side lengths.

[0033] The support formwork 100 is installed vertically on the opening. At this time, the width of the support formwork 100 is converted into its height.

[0034] To improve the connection strength of this embodiment, the support template 100 also includes a fixing buckle 150 and an anti-detachment piece 160. One first sliding member 130 and two second sliding members 140 are arranged as a sliding mechanism. The fixing buckle 150 is disposed on one of the second sliding members 140, and the anti-detachment piece 160 is disposed on the other second sliding member 140.

[0035] In this embodiment, the connection strength is improved by fixing buckle 150, and the second sliding member 140 is prevented from disengaging from the first sliding member 130 by anti-detachment piece 160.

[0036] Adjacent support templates 100 are hinged together. At a connection node, an extension 120 on one support template 100 is provided with a first hook block 121, and an extension 120 on an adjacent support template 100 is provided with a second hook block 122.

[0037] In this embodiment, the first hook block 121 and the second hook block 122 are both J-shaped hook blocks. The opening direction of the J-shaped hook block is parallel to the length direction of the support template 100. After the two adjacent support templates 100 are assembled, the opening directions of the first hook block 121 and the second hook block 122 are set perpendicular to each other, thereby restricting the horizontal movement of the connecting steel column 123 and achieving the effect of hinge.

[0038] Please see Figure 1 , Figure 4 and Figure 5 The first fastening mechanism 200 includes a first fastening member 210 and a second fastening member 220, the first fastening member 210 and the second fastening member 220 cooperating to fix the connection node.

[0039] The first fastener 210 is provided with a first opening groove 211, and the second fastener 220 is provided with a second opening groove 221. The openings of the first opening groove 211 and the second opening groove 221 are arranged facing each other and together define a receiving groove. The two hinge shafts a are located in the receiving groove, and each hinge shaft a abuts against the groove wall of the receiving groove.

[0040] The first opening groove 211 and the second opening groove 221 are both trapezoidal grooves, and the opening positions of the first opening groove 211 and the second opening groove 221 are the positions of the long side of the trapezoidal groove, and the bottom of the first opening groove 211 and the second opening groove 221 are the positions of the short side of the trapezoidal groove.

[0041] In this embodiment, the size of the first opening groove 211 can be set to be larger than the size of the second opening groove 221. Therefore, after assembly, the first opening groove 211 and the second opening groove 221 can achieve the function of limiting the position.

[0042] A first fastening member 210 and a second fastening member 220 constitute a first fastening mechanism 200. There are multiple sets of first fastening mechanisms 200. On each extension member 120, the number of fixing blocks 124 is consistent with the number of first fastening mechanisms 200 and corresponds one-to-one. Multiple sets of first fastening mechanisms 200 are arranged at intervals along the width direction of the template body 110. Multiple first fastening members 210 are provided with first fixing members 230, and multiple second fastening members 220 are provided with second fixing members 240. The second fixing members 240 and the first fixing members 230 are fixedly connected by fasteners 250.

[0043] In this embodiment, the first fixing member 230 and the second fixing member 240 are two flat plates arranged in parallel.

[0044] In this embodiment, the distance between the first fixing member 230 and the second fixing member 240 is adjusted by rotating the fastener 250. In this embodiment, the first fastener 210, the second fastener 220, the first fixing member 230, the second fixing member 240 and the fastener 250 form a stable overall structure to prevent the structure from detaching and to provide good support for subsequent pouring.

[0045] Please see Figure 1 , Figure 6 and Figure 7 Each second fastening mechanism 300 includes a first connector 310 and a second connector 320. The first connector 310 and the second connector 320 slide along the length direction of the second fastening mechanism 300. The first connector 310 is hinged to an extension 120 of a support template 100, and the second connector 320 is hinged to an extension 120 of an adjacent support template 100.

[0046] At a connection node, the first connector 310 is hinged to a fixed block 124 via hinge axis a, and the second connector 320 is hinged to another fixed block 124 via hinge axis a.

[0047] One end of the first connector 310 is provided with a first U-shaped groove 3111, and one end of the second connector 320 is provided with a second U-shaped groove 322. The openings of the first U-shaped groove 3111 and the second U-shaped groove 322 are arranged opposite to each other. One hinge shaft a is located in the first U-shaped groove 3111, and the other hinge shaft a is located in the second U-shaped groove 322.

[0048] Each second fastening mechanism 300 also includes a screw 330, the first connector 310 is provided with a sliding groove, the sliding groove and the first U-shaped groove 3111 are not connected to each other, the second connector 320 is provided with a movable groove 321, the movable groove 321 and the second U-shaped groove 322 are not connected to each other, and the screw 330 passes through the sliding groove and the movable groove 321.

[0049] During manufacturing, the first connector 310 is composed of a U-shaped block 311, a connecting strip 312, and a fixing frame 313. The U-shaped block 311 is provided with a first U-shaped groove 3111. The two connecting strips 312 are arranged in parallel, and one end of each connecting strip 312 is fixedly connected to the U-shaped block 311, and the other end is fixedly connected to the fixing frame 313. The fixing frame 313 is a square frame, and the fixing frame 313 and the two connecting strips 312 together define the sliding groove.

[0050] The fixed frame 313 serves as a guide frame. In this embodiment, the outer dimension of the second connector 320 can be set to be smaller than the inner dimension of the fixed frame 313. The second connector 320 is provided with a threaded hole 323, which communicates with the movable groove 321. The threaded hole 323 is located at the end of the second connector 320 away from the second U-shaped groove 322.

[0051] The screw 330 passes through the fixed frame 313 and is threaded into the threaded hole 323.

[0052] During installation, rotating the screw 330 changes the relative position of the first connector 310 and the second connector 320, thereby adjusting and fixing the length of the second fastening mechanism 300. Due to the hinged relationship between the second fastening mechanism 300 and the two adjacent extensions 120, adjusting the length of the second fastening mechanism 300 can adjust the included angle of the two adjacent support templates 100, forming a triangular fixed support for the two adjacent support templates 100.

[0053] Please see Figures 1 to 3 Based on the above, this embodiment further explains the formwork support construction method as follows: S100. Measure the length of each side of the polygonal opening and pre-adjust the length of each support template 100 according to the length values ​​of each side.

[0054] S200. Construct the first support template 100 on the first side length of the opening, construct the second support template 100 on the second side length of the opening, connect the first support template 100 and the second support template 100, and install the second fastening mechanism 300 between the first support template 100 and the second support template 100.

[0055] Two adjacent support templates 100 are connected to a connecting steel column 123. Specifically, the first hook block 121 and the second hook block 122 are hinged together by the connecting steel column 123.

[0056] S300. Adjust the second fastening mechanism 300 according to the angle between the first side length and the second side length until the angle between the first support template 100 and the first support template 100 is equal to the angle between the first side length and the second side length.

[0057] S400. Continue construction of the remaining 100 support formwork.

[0058] The remaining edges of the opening are fixed in the same way. The last connection node cannot be fixed by the second fastening mechanism 300. That is, except for the last connection node, all other connection nodes are supported and fixed by the second fastening mechanism 300. The last connection node here refers to the last connection point constructed. The order of connection nodes is defined according to the construction order.
