DETAILED DESCRIPTION

[0036] In order to better control the appearance quality of vertical components such as sump pits and cast-in-place wellbores, workers generally make multi-directional inward supports for reinforcement to prevent them from deforming due to mold expansion. However, this process is relatively cumbersome and is prone to damage to the appearance due to inadequate reinforcement.

[0037] In response to the above problems, the present invention provides a tool-type formwork internal support device and method. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] In order to illustrate the tool-type template internal support device and method provided by the present invention, Figures 1-4 The embodiments of the present invention are exemplarily indicated.

[0039] The following description of exemplary embodiments is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses. Techniques and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques and devices should be considered part of the specification.

[0040] like Figure 1-Figure 3 As shown together, an embodiment of the present invention provides a tool-type internal support device for a formwork, comprising a through vertical connecting rod 1, and a transverse supporting mechanism arranged on the vertical connecting rod in sequence from top to bottom; wherein, an inflation hole 2 is provided on the vertical connecting rod 1; gas can be filled into the vertical connecting rod 1 through the inflation hole 2; the transverse supporting mechanism comprises a transverse support rod 3 connected and fixed to the vertical connecting rod 1, a cylinder 4 arranged in the transverse support rod 3, and a supporting member 5 arranged on the cylinder 4; wherein, when the vertical connecting rod 1 is filled with gas, the gas pushes the cylinder 4 along the transverse support rod 3 to move in a direction away from the vertical connecting rod 1, so that the supporting member 5 abuts against the formwork to be supported.

[0041] There is no specific limitation on the more specific components of the vertical connecting rod and the horizontal supporting mechanism. In this embodiment, at least one row of horizontal supporting mechanisms is arranged at equal intervals on the vertical connecting rod 1; and each row is provided with four symmetrically arranged horizontal supporting mechanisms so that the vertical mechanism receives balanced force support.

[0042] In this embodiment, a closed valve 6 is provided at the top end of the vertical connecting rod 1; the closed valve 6 is used to deflate the vertical connecting rod 1 filled with gas when the formwork does not need support, so that the cylinder 4 moves toward the direction close to the vertical connecting rod, thereby loosening the support of the support member on the formwork.

[0043] In this embodiment, a blocking cap 7 is provided at the bottom end of the vertical connecting rod 1, and the blocking cap 7 is sealed and fixed to the vertical connecting rod 1. The blocking cap is generally in a fixed state. However, when multiple vertical components are deep enough, multiple vertical connecting rods can be connected to increase the overall height of the entire tool-type formwork internal support device. At this time, the blocking cap 7 at the connection can be removed to make the multiple vertical connecting rods formed by the connection connected to be connected.

[0044] The specific connection method is not limited. In this embodiment, a first fixing component 12 is provided at the top end of the vertical connecting rod; a second fixing component 13 is provided at the bottom end of the vertical connecting rod. The first fixing component of one vertical connecting rod and the second fixing component of another vertical connecting rod can be sealed and fixed, so that even when supporting the formwork of a deep vertical component, a splicing method can be used to cope with it. The specific expression method of the first fixing component and the second fixing component is not limited. They can be fixed in the form of a slot or a buckle, or they can be connected in the form of an internal thread and an external thread. In a specific embodiment, the first fixing component is a slot with a groove, and the second fixing component is a buckle with a protrusion, so that the connection is not only convenient but also airtight.

[0045] In this embodiment, the air filling hole is connected to an air pump for filling the vertical connecting rod with air. The corresponding air cylinder 4 includes a housing 14, a first gear rod 8 and a second gear rod 9 disposed in the housing 14, and a gear 10 engaged between the first gear rod 8 and the second gear rod 9.

[0046] In this embodiment, the housing 14 is airtightly arranged inside the transverse support rod; the first gear rod 8 extends in a direction away from the vertical connecting rod and is slidably fixed to the upper inner wall of the transverse support rod; the second gear rod 9 extends in a direction close to the vertical connecting rod and is slidably fixed to the lower inner wall of the transverse support rod; a supporting rod 11 is provided at one end of the first gear rod away from the vertical connecting rod. Figure 3 That is, it shows the cylinder arranged in the horizontal support rod on the left side of the vertical connecting rod. When the gas pushes the cylinder housing to the left, the gear rotates counterclockwise, causing the second gear rod to move toward the vertical connecting rod and the first gear rod to move away from the vertical connecting rod. The first gear rod drives the supporting rod to move away from the vertical connecting rod, thereby moving the four supporting parts outward (towards the direction away from the vertical connecting rod) at the same time, and then they can tightly rest against the template to be supported, thereby supporting the template.

[0047] In this embodiment, the supporting rod is fixedly connected to the supporting member; and the supporting member is a U-shaped support plate, which improves the stability of the supporting rod and the supporting member, and improves the supporting effect of the supporting member on the template.

[0048] In a more specific embodiment, the vertical connecting rod can be made of a steel pipe with a length of 250mm, a cross-cut side length of 50mm or a cross-cut diameter of 50mm, and a 10mm diameter air filling hole is set; a cylinder with a cylinder diameter of 25mm and a rod length of 300mm is used, and a supporting rod with a diameter of 30mm is used, and a U-shaped support plate with a thickness of 4-5mm is placed on the top. According to the depth of the vertical component, one or more tool-type internal support devices of the template are selected for splicing so that the air filling holes are connected, and the uppermost and lowermost ends are blocked to prevent air leakage. An air filling hole at the top can be selected to connect to an external air pump, and the air cylinder is pressurized through the air filling hole so that it can freely expand and contract. The other air filling holes can be sealed, thereby supporting and holding up the wooden squares or other horizontal reinforcement components in the vertical component to increase the supporting force; when retracting, the air is released through the sealing valve to retract the cylinder.

[0049] As described above, the tool-type internal formwork support device provided by the present invention can be used to support its formwork with vertical components of different depths, thereby improving construction progress and quality, and increasing turnover times and safety factors.

[0050] like Figure 4 As shown, the present invention also provides a tool-type formwork internal support method, using the tool-type formwork internal support device as described above to support vertical components, the method comprising:

[0051] S1: placing the vertical connecting rod in the middle of the vertical member;

[0052] S2: Fill the vertical connecting rod with gas through the inflation hole, so that the gas spreads to the transverse support rod connected and fixed to the vertical connecting rod, and pushes the cylinder along the transverse support rod to move away from the vertical connecting rod, so that the supporting member rests against the template to be supported.

[0053] For a more specific implementation of the above-mentioned tool-type formwork internal support method, please refer to the specific embodiment of the above-mentioned tool-type formwork internal support device, which will not be described in detail here.

[0054] The above description of the tool-type internal formwork support device and method according to the present invention is provided by way of example with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications may be made to the tool-type internal formwork support device and method without departing from the scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
