Description

Technical Field

[0001] This utility model relates to the field of construction technology combining alloy formwork and wooden formwork, and specifically to a construction structure that connects alloy formwork and wooden formwork. Background Technology

[0002] Since standardized formwork cannot be used directly on non-standard floors, and standardized alloy formwork is not easy to process on site, using a combination of standard alloy formwork and wooden formwork on non-standard floors is a better solution. This can save on the amount of formwork and help reduce construction costs.

[0003] To address the issues of different materials and connection methods between aluminum alloy formwork and wooden formwork, which are not interchangeable and have complex structures, Chinese Patent Publication No. CN220521994U discloses a connection structure for aluminum alloy formwork and wooden formwork, including: aluminum alloy formwork (1); wooden formwork (2); and connectors (3), including a first connecting plate (4) and a second connecting plate; the first connecting plate and the second connecting plate are vertically connected; the outer wall of the first connecting plate is connected to one end surface of the aluminum alloy formwork (1); and the outer wall of the second connecting plate is connected to the side wall of one end of the wooden formwork (2). This utility model connects the aluminum alloy formwork and wooden formwork using connectors, which then abut against the reinforced concrete wall. By fixing the aluminum alloy formwork and wooden formwork on both sides of the connectors, they form an integrated formwork system, ensuring a reliable connection and preventing quality problems such as grout leakage and misalignment. The connectors simplify the structure and installation process, improving on-site installation efficiency.

[0004] However, this technique has the following shortcomings: 1. During construction, the wooden formwork may be damaged on both sides due to the connection and fixation, affecting the secondary use of the wooden formwork; 2. The use of self-drilling screws requires the use of power tools and is not easy to connect metal connectors.

[0005] Therefore, a construction structure connecting alloy formwork and wooden formwork was proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a construction structure that connects alloy formwork and wooden formwork without damaging the wooden formwork during construction, making construction easier.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides a construction structure for connecting alloy formwork and wooden formwork, including alloy formwork, wooden formwork and connector. The connector is formed by folding a flat plate at a right angle. One side of the connector is connected to one end face of the alloy formwork, and the other side is in contact with the rear side of the wooden formwork. A thin-walled corner bracket is connected between the alloy formwork and the connector, and the wooden formwork is clamped between the thin-walled corner bracket and the connector.

[0009] Preferably, the end face of the alloy template is provided with multiple connecting holes at equal intervals.

[0010] Preferably, one side of the thin-walled corner bracket is provided with at least two holes spaced apart, and the distance from the center of the hole to the other side is equal to the distance from the center of the connecting hole on the side of the alloy template to the front of the alloy template.

[0011] Preferably, the wall thickness of the thin-walled corner bracket is 0.3mm-2mm, more preferably 1mm.

[0012] Preferably, the connector has at least two holes spaced apart on the surface for connecting the alloy template. The distance from the center of the hole to the other side is equal to the difference between the distance from the center of the connecting hole on the side of the alloy template to the front of the alloy template and the thickness of the wooden template.

[0013] Preferably, the connector is an angle steel or an aluminum angle.

[0014] Preferably, the wall thickness of the connector is 3mm-5mm.

[0015] Preferably, the alloy template and the connector are connected by bolts or pins.

[0016] Preferably, the construction structure connecting the alloy formwork and the wooden formwork further includes a back rib, timber, and tie bolts. The back rib is connected to the back of the alloy formwork via the tie bolts, and the timber is clamped between the back rib and the wooden formwork.

[0017] Preferably, the construction structure connecting the alloy template and the wooden template further includes a central seam timber and a T-shaped tie rod. The central seam timber has a long seam running through its two opposite sides along its length direction. The central seam timber is tightened between the back rib and the wooden template. The T-shaped tie rod is sandwiched between the side end faces of the wooden template, and the insertion surface of the T-shaped tie rod passes through the long seam and is fixed by a tensioning member.

[0018] Preferably, the tensioning element is a pin.

[0019] Preferably, the T-shaped pull bar has a hole on its insertion surface for inserting a pin.

[0020] Due to the adoption of the above technical solutions, the advantages of this utility model are as follows:

[0021] 1. This utility model eliminates the need for nails or screws, preventing damage to the wooden formwork and facilitating reuse. It also eliminates the need for nails or screws to penetrate softer connectors such as angle steel, making fixing and disassembly easier and improving construction efficiency. Furthermore, it allows for the selection of harder connectors such as angle steel, making component selection more flexible.

[0022] 2. The center seam timber and T-shaped tie rod provided by this utility model facilitate the splicing of multiple wooden formwork pieces in a wider area, which helps to reduce the construction difficulty or number of personnel required for simultaneous support of multiple wooden formwork pieces, and makes full use of existing conventional-sized wooden formwork pieces.

[0023] 3. This utility model uses timber and back bracing for further reinforcement, making the construction structure more reliable and practical. Attached Figure Description
