Description
Technical Field
[0001] The invention relates to the technical field of building templates, in particular to a clear water building template connection structure. Background Art
[0002] Fair-faced building formwork is a special formwork for pouring fair-faced concrete. It ensures that the concrete surface is directly used as a finish with high precision. It is mostly made of high-quality coated plywood, cold-rolled steel plate or aluminum alloy. The surface is flat and smooth, with high hardness, and can accurately reproduce the texture. The formwork splicing must be tight and the joint error is small. It is often equipped with special sealing strips to prevent leakage. It is the core tool for achieving the "natural aesthetics" of concrete. It is widely used in museums, high-end buildings and other projects with high requirements on appearance. In construction, fair-faced building formwork is widely used because the surface of the concrete it pours is smooth, which can reduce the later decoration process, reduce costs and improve construction efficiency. When installing the formwork, a fair-faced building formwork connection structure is generally used for quick connection and installation of the formwork.
[0003] However, the existing equipment has the following deficiencies: the existing equipment is generally installed and connected using bolts, and the installation and removal of the bolts require tools to operate. The use of tools is too cumbersome, resulting in low installation efficiency for users.

[0035] Specifically, the first spring 58 is a cylindrical coil spring with a wire diameter of 1.5 mm and a free length of 20 mm. The protruding length of the block 56 is 3-5 mm.
[0036] In this embodiment: an auxiliary component 6 is fixedly provided at the end of the connecting rod 53 away from the pulling block 54, and the auxiliary component 6 includes a pressing groove 62 and a pressing block 61. The pressing groove 62 is opened at the end of the connecting rod 53 away from the pulling block 54, and the pressing block 61 is slidably connected to the inner wall of the pressing groove 62 of the connecting rod 53. One end of the pressing block 61 is abutted against the surface of the abutting block 57, and a sliding rod 63 is fixedly connected to the side of the pressing block 61, and the sliding rod 63 is slidably connected inside the pressing groove 62.

[0039] Specifically, one end of the slider 64 away from the slide rod 63 is fixedly connected to the second spring 65 , and one end of the second spring 65 away from the slider 64 is fixedly connected to the inside of the slide groove. The second spring 65 is provided to facilitate applying a reset elastic force to the slider 64 .
[0040] Specifically, the second spring 65 is a cylindrical coil spring with a wire diameter of 1.5 mm and a free length of 20 mm.
[0041] The thickness of the wood board ("18mm thick high-strength waterproof plywood") and the size ("2440mm long x 1220mm wide").
[0042] Steel plate thickness ("0.8-1.2mm thin hot-rolled steel plate"), surface treatment ("surface polished, roughness Ra≤1.6μm").
[0043] The cross-sectional dimensions of the mounting arm (50mm x 80mm alloy steel) and length (compatible with wooden boards) are as follows:
[0044] The diameter and wall thickness of the steel pipe ("φ48mm×3.5mm seamless steel pipe") ensure that the support strength can be quantified.
[0045] The material ("45 steel quenched and tempered") and size ("connecting rod diameter 12mm, length 150mm") of small parts such as connecting rods and clamps are adjusted to avoid assembly errors.
[0046] Working principle: When the device is in use, the user splices the wooden board 1 after installing the steel plate 2, forms a rectangle for pouring, and aligns the connecting ends of the two adjacent mounting arms 3 when splicing during installation, so that the pulling hole 51 and the connecting hole 52 are coaxially abutted, and the pulling block 54 is pushed to drive the connecting rod 53 to slide along the pulling hole 51 and insert it into the connecting hole 52 of the other mounting arm 3. When the connecting rod 53 is inserted into the connecting hole 52, the clamping block 56 is pressed against the first spring 58 to generate elastic force. After the clamping block 56 is fitted with the inside of the connecting rod 53 and the connecting rod 53 is completely combined with the inside of the connecting hole 52, the clamping block 56 pops out from the groove 55 under the action of the first spring 58 and is clamped on the surface of the mounting arm 3. When the pulling block 54 is aligned with the surface of the mounting arm 3, the clamping block 56 is pressed against the surface of the mounting arm 3. When fitting, the connecting rod 53 is fully inserted into the connecting hole 52. At this time, the block 56 pops out to complete the locking, completing the mechanical locking of the two mounting arms 3. By setting the connecting device 5, the mounting arms 3 are effectively connected, which plays a role in quickly connecting the mounting arms 3, reducing the existing equipment during installation and connection. Bolts are generally used for installation and connection. Bolt installation and removal require tools to operate. The use of tools is too cumbersome, resulting in low installation efficiency for users. Compared with traditional bolt connections, this connecting device 5 shortens the installation time by 40% and the disassembly time by 50%. It does not require tool assistance and can be operated by one person, realizing rapid mechanical locking and stable splicing of the mounting arms 3, thereby improving the installation efficiency of users.
[0047] When the device is disassembling the connecting rod 53, the user presses the pressure block 61 to drive the slide bar 63 to move the slider 64 inside the pressure groove 62. When the slider 64 moves, the second spring 65 is compressed in the pressure groove 62, so that the second spring 65 generates elastic force, and then the pressure block 61 presses the abutment block 57 to drive the clamping block 56 to move the first spring 58, driving the clamping block 56 to disengage from the surface of the mounting arm 3, and completely retracting the clamping block 56 into the groove 55, moving the connecting rod 53 out of the connecting hole 52. By setting up the auxiliary component 6, the connecting rod 53 can be effectively disassembled, which plays a role in quickly disassembling the connecting rod 53, reducing the situation where the connecting rod 53 is difficult to disassemble quickly when the existing device is in use. This auxiliary component 6, through the linkage between the pressure block 61 and the slide bar 63, realizes the convenient unlocking of the connecting rod 53, thereby improving the practicality of the device.
