Description

Technical Field

[0001] The utility model relates to the field of installation and connection of thermal insulation templates, in particular to an installation and connection piece of a thermal insulation template that does not require mold removal. Background Art

[0002] As the concept of environmental protection becomes more and more popular and the concept of green building is promoted, the construction industry has higher and higher requirements for building materials. Traditional building formwork has problems such as cumbersome formwork and dismantling, long construction period, large material waste, and poor insulation effect. Therefore, non-dismantling insulation formwork has emerged as a new type of building material, aiming to solve these problems and promote the green development of the construction industry.

[0003] After searching, the existing Chinese patent announcement number is: CN220538971U, which provides an insulation-free formwork connector with a steel bar fixing groove. By pre-installing installation perforations on the insulation-free formwork and opening a steel bar fixing groove on the screw rod, the steel bar and the insulation-free formwork are fixed by the connector; by designing a conical screw rod, the connection stability between the insulation-free formwork and the concrete layer is enhanced.

[0004] Although the above patent can enhance the connectivity between the thermal insulation non-disassembly formwork and the concrete layer to a certain extent, the above-mentioned thermal insulation non-disassembly formwork connector with a steel bar fixing groove still has the following problem: when the concrete layer is poured thickly, the connector cannot be fully and firmly connected to the concrete layer.

[0005] In view of the above problems, an installation connector for a heat-insulating formwork that does not require demolding is proposed. Utility Model Content

[0006] The utility model aims to provide an installation connector for a heat-insulating formwork that does not require demolding, thereby solving the problem in the background art that the formwork cannot be fully fastened and connected to a concrete layer.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an installation and connection part of a mold-free thermal insulation template, comprising a fixed base plate, characterized in that: a second sleeve is fixedly connected to the right side of the fixed base plate, a second slot is provided on the outer wall of the second sleeve, a fixed shaft is arranged on the right side of the second slot, short plug rods are unevenly distributed on the outer ring of the fixed shaft, long plug rods are unevenly distributed on the outer ring of the fixed shaft, a connecting shaft is fixedly connected to the left side of the fixed shaft, a block is fixedly connected to the outer ring of the connecting shaft, a first sleeve is fixedly connected to the right side of the fixed shaft, a first slot is provided on the outer wall of the first sleeve, a threaded sleeve is fixedly connected to the left side of the fixed base plate, a second screw is provided on the left side of the threaded sleeve, and a tightening assembly is provided on the left side of the fixed base plate.

[0008] By adopting the above technical solution, the fixed shaft is screwed into the second sleeve through the connecting rod, and is clamped into the slot through the clamping block. When the poured concrete is thicker, the same fixed shaft is screwed into the first sleeve to extend the connecting piece, thereby ensuring the tightness of the connection between the connecting piece and the concrete layer, and the short plug rod and the long plug rod can enhance the tightness with the concrete layer.

[0009] As a further description of the above technical solution: the tightening assembly includes a base, the base is fixedly connected to the left side of the second screw rod, a plug hole is opened on the left side of the base, and a tightening slot is opened in the middle of the base.

[0010] By adopting the above technical solution, when two or more layers of insulation templates are needed, the insulation templates can be aligned with the openings and the connection between the multiple layers of insulation templates can be made tighter by tightening the first screw and the threaded sleeve, ensuring that the insulation effect reaches the expected goal.

[0011] As a further description of the above technical solution: the fixed base plate is threadedly connected with a first screw rod.

[0012] By adopting the above technical solution, the bottom plate can be fixed to the inner side of the thermal insulation template.

[0013] As a further description of the above technical solution, a gasket penetrates and is slidably connected to the outer ring of the first screw.

[0014] By adopting the above technical solution, the gasket can improve the connectivity and tightness between the screw and the half.

[0015] As a further description of the above technical solution: a nut is fixedly connected to the right side of the first screw.

[0016] By adopting the above technical solution, the screw can be screwed into the thermal insulation template by rotating the nut.

[0017] As a further description of the above technical solution: a latch is passed through and slidably connected to the right side of the base.

[0018] By adopting the above technical solution, when the base is screwed into the thermal insulation template, the insertion pin is prevented from being activated and its fastness is enhanced.

[0019] As a further description of the above technical solution: a tightening handle is provided on the left side of the base.

[0020] By adopting the above technical solution, the tightening handle can easily exert force to ensure that the screw is tightened.

[0021] As a further description of the above technical solution: a tightening plate is fixedly connected to the right side of the tightening handle.

[0022] By adopting the above technical solution, the tightening plate can be inserted into the tightening slot to achieve the purpose of tightening the screw and the threaded sleeve.

[0023] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0024] 1. The utility model provides an installation connector for a heat-insulating formwork that does not require demolding. First, a sleeve is provided, and a slot is provided on the surface of the sleeve. A fixed shaft can be directly screwed into the sleeve. When the poured concrete layer is thicker, another identical fixed shaft can be directly screwed into the sleeve of the fixed shaft, ensuring that the connector is fully and firmly connected to the concrete layer and that the plug rod on the surface of the fixed shaft can enhance its fastness to the concrete layer.

[0025] 2. The utility model provides an installation connector for a heat-insulating template that does not require mold removal. By setting a tightening component, when two or more layers of heat-insulating templates are needed, the heat-insulating templates are aligned and holes are opened, and the screws and threaded sleeves are respectively inserted into both sides of the heat-insulating templates and then tightened. This can reduce the gap between the heat-insulating templates and ensure a good heating effect. The cooperation between the pin and the socket can prevent the screw from loosening in the threaded sleeve, so that the heat-insulating template can always fit tightly.

[0033] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0034] Combination Figure 1 The utility model is a mounting connector for a heat preservation template that does not require mold removal, including a fixed base plate 10, a first screw rod 13 is threadedly connected to the left side of the fixed base plate 10, a gasket 12 is penetrated and slidably connected to the outer ring of the first screw rod 13, a nut 11 is fixedly connected to the right side of the first screw rod 13, a base 16 is arranged on the left side of the fixed base plate 10, and a latch 18 is penetrated and slidably connected to the right side of the base 16. After the threaded sleeve is inserted into the hole opened in the heat preservation template, the threaded rod 13 is screwed into the heat preservation template, and the latch on the base can be inserted into the heat preservation template after the base is attached to the heat preservation template to enhance its fastness.

[0035] Combination Figure 2 and Figure 3 A second sleeve 8 is fixedly connected to the right side of the fixed base plate 10, and a second slot 9 is provided on the outer wall of the second sleeve 8. A fixed shaft 3 is arranged on the right side of the second slot 9. Short plug rods 4 and long plug rods 5 are unevenly distributed on the outer ring of the fixed shaft 3. A connecting shaft 6 is fixedly connected to the left side of the fixed shaft 3, and a clamping block 7 is fixedly connected to the outer wall of the connecting shaft 6. A first sleeve 1 is fixedly connected to the right side of the fixed shaft 3, and a first slot 2 is provided on the outer wall of the first sleeve 1. When the fixed base plate 10 is fixed to the surface of the insulation formwork, the connecting shaft 6 is screwed into the second sleeve, and the clamping block 7 is clamped into the second slot 9. When the concrete layer to be poured is thicker and the connecting piece is shorter, the same fixed shaft 3 can be taken again, and the connecting shaft of the fixed shaft 3 is screwed into the first sleeve 1 of the previous fixed shaft 3, so that the connecting piece is lengthened.

[0036] Combination Figure 4 The tightening assembly includes a base 16, which is fixedly connected to the left side of the second screw 15. A plug hole 17 is opened on the left side of the base 16, and a tightening groove 19 is opened in the middle of the base 16. When the second screw 15 and the threaded sleeve 14 are inserted into the same hole opened in the insulation template, the tightening plate set on the left side of the base 16 is inserted into the tightening groove 19, and then the tightening handle 20 is rotated to screw the second screw 15 into the threaded sleeve 14 and reduce the spacing of the insulation template.

[0037] Working principle: After the holes are opened in the insulation template, the threaded sleeve 14 is inserted into the opened holes. When the fixed base plate 10 is in contact with the surface of the insulation template, the first screw 13 is screwed into the insulation template. At this time, the threaded sleeve 14 and the fixed base plate 10 are fixed on the insulation template. At this time, the connecting shaft 6 is inserted into the second sleeve 8, and the block 7 is inserted into the slot 9. At this time, under the action of the connecting shaft 6, the fixed shaft 3 is also in contact with the second sleeve 8. If the concrete layer to be poured is thicker, take the same fixed shaft 3 and insert its connecting shaft 6 into the first sleeve 1 of the previous fixed shaft 3, and then insert the block 7 into the slot 9. The operation can be repeated until the length of the connecting piece meets the casting thickness of the concrete layer. When the fixed shaft 3 is installed, the second screw 15 is inserted into the corresponding hole. At this time, the tightening plate 21 is inserted into the tightening slot 19 and then the tightening handle 20 is rotated. When the base 16 is tightly fitted to the other side of the insulation template, the rotating handle 20 is removed and the latch 18 is inserted into the insertion hole 17 and then into the insulation template to prevent the second screw rod 15 from loosening.
