Description

Technical Field

[0001] The invention relates to the technical field of template caulking, in particular to a FS composite thermal insulation external template caulking tool and a construction method thereof. Background Art

[0002] As my country's economic development accelerates, construction project requirements are becoming increasingly stringent, and the importance of energy-saving and environmental protection projects is becoming increasingly prominent. While traditional insulated walls have relatively good performance, they consume a lot of energy and have a long construction period. Against this backdrop, the application of FS composite insulated exterior formwork meets engineering environmental standards and further enhances the overall quality of the building. FS composite insulated exterior formwork is a permanent exterior formwork that is integrally poured with the concrete during cast-in-place concrete construction. Connectors securely connect the insulation formwork to the concrete wall, forming a cavity-free composite insulated structural wall. The insulation layer provides thermal insulation and reduces heat transfer. The bonding layer and connectors ensure a tight connection and coordinated operation between the layers. Strengthening ribs and insulation transition layers enhance the formwork's strength, stability, and crack resistance, enabling the entire system to withstand various external forces and environmental factors.

[0003] After the installation of traditional FS composite insulation external formwork, there is a problem of large joints between adjacent formworks, which leads to leakage. In order to solve this problem, a FS composite insulation external formwork joint sealing tool and a construction method are proposed. Summary of the Invention

[0004] The object of the present invention is to provide a FS composite thermal insulation outer formwork caulking tool and a construction method thereof, so as to solve the defects mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, a FS composite thermal insulation outer formwork caulking tool is provided, including a caulking tool, the top of the caulking tool is covered with a wooden square, and a FS composite thermal insulation outer formwork is provided on one side of the caulking tool. The caulking tool is inserted between two adjacent groups of FS composite thermal insulation outer formworks. A flange is provided on the caulking tool, and the flange covers the upper surface of the FS composite thermal insulation outer formwork. A rectangular steel bar is fixedly provided at the bottom of the flange, the outer side of the flange is provided at the upper part of the flange, and the inner side of the flange is provided at the lower part of the flange. Limiting strips are fixedly provided at both ends of the surface of the flange, and a positioning groove is formed between the two groups of limiting strips. The bottom of the wooden square is inserted into the positioning groove.

[0006] Furthermore, the cross-section of the caulking tool is T-shaped, and the caulking tool also includes a filling piece, which covers the outer surface of the caulking tool.

[0007] Furthermore, an upper sealing gasket is provided on the filling piece, a lower sealing gasket is fixedly provided on the bottom of the upper sealing gasket, the upper sealing gasket and the lower sealing gasket are combined together to form an "L" shape, and the thickness of the upper sealing gasket and the lower sealing gasket are consistent.

[0008] Furthermore, the upper sealing gasket covers the bottom of the flange, the lower sealing gasket covers the side wall of the rectangular steel bar, and the filling piece also includes a docking seat and a docking groove.

[0009] Furthermore, four groups of docking grooves are evenly arranged on the bottom of the flange, and five groups of docking grooves are evenly arranged on both sides of the rectangular steel bar. Docking seats are fixedly provided on the upper sealing gasket and the lower sealing gasket.

[0010] Furthermore, the sizes of the docking seat and the docking groove are adapted to each other, the docking seat is inserted into the interior of the docking groove, the cross-sections of the docking seat and the docking groove are isosceles trapezoidal, the caulking tool is inserted into the joint between two adjacent sets of FS composite insulation outer formwork and sealed by a filling piece, and the filling piece is a rubber pad.

[0011] Another object of the present invention is to provide a construction method of a FS composite thermal insulation outer formwork caulking tool, using the above-mentioned FS composite thermal insulation outer formwork caulking tool, and the specific steps are as follows:

[0012] Insert the rectangular steel bar at the bottom of the caulking tool into the joint between two adjacent sets of FS composite insulation outer formwork. Place the flange at the top of the caulking tool close to the FS composite insulation outer formwork and use wooden planks to support the flange.

[0013] At this time, the upper sealing gasket covering the bottom of the flange is tightly attached to the upper surface of the joint between the two adjacent sets of FS composite insulation outer formwork, forming a horizontal sealing barrier; the lower sealing gasket covers the side wall of the rectangular steel bar, filling the vertical gap of the joint between the two adjacent sets of FS composite insulation outer formwork, forming a lateral seal. At the same time, the rectangular steel bar squeezes the lower sealing gasket tightly against the side wall of the FS composite insulation outer formwork.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This solution uses a caulking tool inserted into the joint between two adjacent sets of FS composite insulation outer formwork. The top flange of the caulking tool is in close contact with the FS composite insulation outer formwork, and wooden planks are used to support the flange to ensure the stability of the caulking tool during operation. This can effectively prevent grout leakage at the joints of the FS composite insulation outer formwork, significantly improve the forming quality, and is simple to operate and convenient to construct. This solves the problem of poor control of the forming quality of the insulation outer formwork and grout leakage at the joints caused by traditional construction methods.

[0016] 2. This solution uses an upper sealing gasket covering the bottom of the flange to fit snugly against the upper surface of the formwork joint, forming a horizontal sealing barrier that directly blocks the path for concrete slurry to seep out from the top of the joint. Simultaneously, the rigid structure of the flange supports the upper sealing gasket, making it less likely to deform under the pressure of concrete vibration, ensuring a continuously effective seal. The lower sealing gasket, covering the side walls of the steel bars, fills the vertical gap in the formwork joint, forming a lateral seal. This simultaneously prevents slurry and rainwater from penetrating from the top and sides of the joint, improving both leakage prevention and waterproofing. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1-6 The present invention provides a FS composite thermal insulation outer formwork caulking tool, including a caulking tool 1, the top of the caulking tool 1 is covered with a wooden square 5, and a FS composite thermal insulation outer formwork 4 is arranged on one side of the caulking tool 1. The caulking tool 1 is inserted between two adjacent groups of FS composite thermal insulation outer formworks 4, and a flange 2 is provided on the caulking tool 1. The flange 2 covers the upper surface of the FS composite thermal insulation outer formwork 4, and a rectangular steel bar 3 is fixedly provided at the bottom of the flange 2. A flange outer side 7 is provided on the upper part of the flange 2, and a flange inner side 6 is provided on the lower part of the flange 2. Limiting strips 21 are fixedly provided at both ends of the surface of the flange 2, and a positioning groove 20 is formed between the two groups of limiting strips 21. The bottom of the wooden square 5 is inserted into the positioning groove 20.

[0025] Working principle: When in actual use, the cross-section of the caulking tool 1 is set in a "T" shape. The caulking tool 1 is inserted into the joint between two adjacent groups of FS composite insulation outer formwork 4. The flange 2 on the top of the caulking tool 1 is close to the FS composite insulation outer formwork 4, and the wooden square 5 is used to support the flange 2 to ensure the stability of the caulking tool 1 during work. It can effectively avoid leakage at the joints of the FS composite insulation outer formwork 4, greatly improve the molding quality, simple operation and convenient construction. Since the rectangular steel bar 3 at the bottom of the caulking tool 1 is relatively thin, multiple groups of FS composite insulation outer formwork 4 can be directly stuffed into the joints after splicing, which solves the problem that traditional construction methods are difficult to control the molding quality of the insulation outer formwork and leakage at the joints, avoids the need for construction personnel to make later rectifications in actual construction, and solves the common quality problems and cost problems of construction.

[0026] The upper sealing gasket 101 covering the bottom of the flange 2 can be tightly attached to the upper surface of the formwork joint, forming a horizontal sealing barrier, directly blocking the path of concrete slurry seeping from the top of the joint; at the same time, the rigid structure of the flange 2 can support the upper sealing gasket 101, making it less likely to deform under the pressure of concrete vibration, ensuring continuous and effective sealing; the lower sealing gasket 102 covers the side walls of the steel bar and can fill the vertical gap of the formwork joint to form a lateral seal; the rectangular steel bar 3 serves as a supporting skeleton, which can tightly squeeze the lower sealing gasket 102 against the side walls of the formwork, avoiding sealing failure caused by fluctuations in the gap width, and is particularly suitable for scenarios with irregular joint sizes; it can simultaneously prevent slurry and rainwater from penetrating from the top and sides of the joint, improving the anti-leakage and waterproof performance;

[0027] The upper sealing gasket 101 and the lower sealing gasket 102 are positioned and installed on the caulking tool 1 through the docking seat 103 and the docking groove 104. When the upper sealing gasket 101 and the lower sealing gasket 102 are installed, the sealing gaskets can only be embedded into the caulking tool 1 along the preset direction to avoid skew or deviation due to manual operation.

[0030] The upper sealing gasket 101 covers the bottom of the flange 2 , and the lower sealing gasket 102 covers the side wall of the rectangular steel bar 3 . The filling piece 10 further includes a docking seat 103 and a docking groove 104 .

[0031] As a preferred embodiment, four groups of docking grooves 104 are evenly opened on the bottom of the flange 2, five groups of docking grooves 104 are evenly opened on both sides of the rectangular steel bar 3, and docking seats 103 are fixedly provided on the upper sealing gasket 101 and the lower sealing gasket 102.

[0032] The sizes of the docking seat 103 and the docking groove 104 are adapted to each other, and the docking seat 103 is inserted into the interior of the docking groove 104. The cross-sections of the docking seat 103 and the docking groove 104 are isosceles trapezoidal. The caulking tool 1 is inserted into the joint between two adjacent sets of FS composite insulation outer formwork 4 and is sealed by a filling piece 10, which is a rubber pad.

[0033] The present invention also provides a construction method of the FS composite thermal insulation outer template caulking tool, using the above-mentioned FS composite thermal insulation outer template caulking tool, the specific steps are as follows:

[0034] Insert the rectangular steel bar 3 at the bottom of the caulking tool 1 into the joint between two adjacent sets of FS composite insulation outer formwork 4. Place the flange 2 at the top of the caulking tool 1 close to the FS composite insulation outer formwork 4 and use wooden squares 5 to support the flange 2.
