Description

Technical Field

[0001] This utility model belongs to the field of formwork technology and relates to a heavy-duty formwork structure suitable for construction in confined spaces. Background Technology

[0002] Heavy-duty formwork generally refers to formwork operations with a weight greater than 10kN / m2 or above, or a concentrated line load (design value) of 15kN / m2 or above. Traditional heavy-duty formwork can be operated using ordinary fastener-type steel pipe formwork, portal frame, cup-lock frame, and socket-type formwork.

[0003] For example, Chinese Patent Publication No. CN213573014U discloses a detachable heavy-duty formwork support frame, which includes one or more splicing units. Each splicing unit includes at least a first column, a first crossbar connected between adjacent first columns, a second column rotatably connected to the top of the first column, a second crossbar connected between adjacent second columns, and a movable component. The movable component forms an inclined surface, and the second column forms a cutting surface. When the movable component abuts against the first and second columns and the inclined surface is in contact with the cutting surface, the central axes of the first and second columns are located on the same straight line. When the second crossbar is removed and the movable component is detached from the first and second columns, the first and second columns are detached. This utility model has a large load-bearing capacity. When the formwork support frame is dismantled, the second column and the first column can rotate relative to each other by the lateral detachment of the movable component. By rotating around the hinge, the first and second columns are easy to assemble and disassemble with little effort. The formwork support frame can be reused, saving on usage costs.

[0004] However, the aforementioned formwork support frame has a large span due to the large distance between the two opposing first columns and the fixed length and position of the crossbars, making it unsuitable for use in narrow spaces. Therefore, we designed a heavy-duty formwork support frame structure suitable for construction in narrow spaces. Summary of the Invention

[0005] The purpose of this invention is to provide a heavy-duty formwork structure suitable for construction in confined spaces, in order to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: A heavy-duty formwork structure suitable for construction in confined spaces includes multiple L-shaped columns, multiple horizontal connecting plates, and a working template surface. The multiple horizontal connecting plates are arranged between two adjacent L-shaped columns and connected to the L-shaped columns through a locking plate structure. It also includes multiple wall connecting frames. Each wall connecting frame has a wall clamping cavity on one side of its bottom end. Each L-shaped column has a lower edge connecting rod at one end. Each lower edge connecting rod has an insertion cylinder at one end. The lower edge connecting rod is inserted into the top of the wall connecting frame through the insertion cylinder. Each wall connecting frame has a locking bolt installed on its side. The locking bolt is locked to the bolt of the insertion cylinder.

[0007] In the aforementioned heavy-duty formwork structure suitable for construction in confined spaces, each locking plate structure includes at least one elliptical connecting plate and two corner positioning discs. The two corner positioning discs are mounted on the bolt holes of the elliptical connecting plate using eight bolts, which are then connected to the L-shaped columns. This arrangement utilizes one elliptical connecting plate and two corner positioning discs to form a locking plate structure, allowing every three L-shaped columns and two transverse connecting plates to be assembled together to form a formwork unit. This unit forms the formwork frame, ensuring both strong connection and ease of disassembly.

[0008] In the aforementioned heavy-duty formwork structure suitable for construction in confined spaces, each L-shaped column has an upper reinforcing rod and a lower reinforcing rod welded to its inner side. The upper and lower reinforcing rods are arranged in parallel, and a vertical connecting rod is provided between them. The upper and lower reinforcing rods and the vertical connecting rod are integrally formed. The purpose of this arrangement is to ensure that each L-shaped column has good structural strength and load-bearing capacity, thereby ensuring the overall stability of the formwork.

[0009] In the aforementioned heavy-duty formwork structure suitable for construction in confined spaces, a movable pin is installed at the end of the lower reinforcing rod. A guide portion is provided at the top of the movable pin, through which the movable pin connects to the wall connecting frame. This design aims to connect the lower reinforcing rod to the wall connecting frame via the movable pin and the guide portion, ensuring uniform stress distribution and strong load-bearing capacity.

[0010] In the aforementioned heavy-duty formwork structure suitable for construction in confined spaces, each L-shaped column is equipped with a grounding base at its bottom, each grounding base has a limiting frame at its bottom, each limiting frame has a spiral mounting part at its bottom, and each spiral mounting part has a ground anchor post at its bottom. This design facilitates better installation onto the ground, ensures a firm connection between each grounding base and the ground, and increases the overall structural stability.

[0011] In the aforementioned heavy-duty formwork structure suitable for construction in confined spaces, the tops of multiple L-shaped columns are provided with concave locking slots. The working template surface is secured to the top of each L-shaped column via these slots. This design facilitates the installation of the working template surface on the tops of multiple L-shaped columns to form a working platform, thereby enabling better construction operations.

[0012] Compared with existing technologies, the advantages of this utility model for a heavy-duty formwork structure suitable for construction in confined spaces are as follows: By setting up wall connecting frames, each wall connecting frame has a wall clamping cavity on one side of its bottom end. Each L-shaped column has a lower edge connecting rod and a matching insertion cylinder at one end. The lower edge connecting rod is inserted into the top of the wall connecting frame through the insertion cylinder and locked with the bolts of the insertion cylinder using locking bolts. This allows part of the overall formwork frame to connect with the wall to provide support, and part to contact the ground to provide support, reducing the span and facilitating construction operations in confined spaces. It is also convenient to use. By using movable pins and guide parts to connect with the wall connecting frames, the lower reinforcing rod is connected to the wall connecting frames, ensuring uniform stress distribution and strong load-bearing capacity.
