Description

Technical Field

[0001] The utility model belongs to the technical field of construction and building, and relates to a concrete retaining wall steel formwork component. Background Art

[0002] Concrete is a building material widely used in civil engineering. It is mainly made of sand and gravel aggregates, cement, water, and sometimes chemical admixtures and mineral admixtures mixed in a certain proportion. Concrete is widely used in various structures such as foundations, walls, beams, columns, floors, bridges, tunnels, etc. of buildings. It is also commonly used in infrastructure construction such as roads, dams, ports, and airports.

[0003] When pouring concrete into a wall, the steel bars are first built into structural members according to a specific design. Then, formwork is placed and secured on both sides of the structural members according to the width of the wall to form a cavity. Concrete is then poured into the cavity from top to bottom and vibrated to compact the concrete.

[0004] Traditional formwork is wooden formwork, which is formed by splicing wooden strips into wooden boards, and then reinforcing strips are transversely fixed on the outside of the wooden boards. When pouring concrete, the support rods are supported on the reinforcing strips to improve the strength of the formwork. However, since the formwork is made of wood and has low strength, the formwork will deform when pouring concrete, causing the wall to deform after solidification, reducing the processing quality. At the same time, since the formwork is made of wood, it is easy to be damaged and has a short service life. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and propose a concrete retaining wall steel formwork component, which solves the technical problem of how to increase the service life of the formwork and improve the processing quality of the concrete wall.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a concrete retaining wall steel formwork assembly, comprising at least one pair of relatively arranged main boards, characterized in that it also includes a plurality of tension rods, the main boards are made of steel material, a plurality of fixing strips are arranged on the outer side walls of the main boards at intervals, a fixing groove is provided in the fixing strip, a plurality of fixing holes are arranged at intervals at the bottom of the fixing groove, the tension rod is located between the relatively arranged main boards, the two ends of the tension rod pass through the fixing holes and the fixing grooves, fasteners are sleeved on the two ends of the tension rod and abut against the fixing strips, so that the main board and the tension rod are integrated into one, connecting strips are provided on the left and right ends of the main board, the connecting strips have a plurality of first connecting holes, and the two adjacent main boards located on the same side are locked and fixedly connected after the fasteners pass through the first connecting holes.

[0007] During construction, the steel bars are first built into a structural member according to a specific design, and then the main board is arranged along the structural member. The two adjacent main boards are locked and connected by fasteners passing through the first connecting hole, so that the main boards form two rows. The fasteners are a combination of bolts and nuts. Then, the tension rod is inserted between the relatively arranged main boards through the fixing groove and the fixing hole, and the two ends of the tension rod are exposed outside the fixing strip. Then, the fastener is set on the two ends of the tension rod and abuts against the fixing strip, and the tension rod is locked, so that the main board and the tension rod are integrated into one to form a steel formwork assembly. The steel formwork assembly encloses a mold cavity of a retaining wall, and then concrete is poured into the mold cavity. The fastener is a combination of nuts and gaskets. The main board of the steel formwork assembly is made of steel material, which is not easy to be damaged compared to the main board made of wood material, which improves the service life of the formwork. The main board is pulled by the tension rod so that the main board will not deviate from the set position, so that the cast concrete wall will not be deformed, and the processing quality of the concrete wall is improved. After the processing is completed, the tension rod can be taken out and the hole can be repaired, or the tension rod can be directly placed in the wall to improve the wall strength.

[0008] In the above-mentioned concrete retaining wall steel formwork assembly, a plurality of reinforcing ribs are arranged at intervals on the outer wall of the main board, and the reinforcing ribs are fixedly connected to the fixing bars and are arranged in a criss-cross grid. The arrangement of the reinforcing ribs, in conjunction with the fixing bars, improves the strength of the main board, so that the main board will not be damaged or deformed during use, thereby increasing the service life of the formwork and improving the processing quality of the concrete wall.

[0009] In the above-mentioned concrete retaining wall steel formwork assembly, the bottom of at least one of the pair of relatively arranged main boards is bent outward to form a base, and a mounting frame for mounting a vibrator is fixedly connected to the base. The setting of the base is adapted to the shape of the wall to be formed, and the vibrator is installed on the mounting frame. The vibrator can drive the main board to vibrate, so that the concrete can become more compact, and the processing quality of the concrete wall is improved. The mounting frame is located at the bottom of the main board, which has a better vibration effect.

[0010] In the above concrete retaining wall steel formwork assembly, the mounting frame includes a bottom plate and a positioning plate, both ends of the bottom plate are fixedly connected to the reinforcing ribs, the positioning plate is fixedly connected to the bottom of the bottom plate, and the positioning plate and the bottom plate are perpendicular. The structure is simple and the installation firmness of the vibrator is improved.

The setting of the fixing block is adapted to the inclined base, the through hole is for the tension rod to pass through, and the outer wall of the fixing block is arranged in the vertical direction for the fastener to abut against, so that the fastener can better lock the tension rod, improve the stability of the steel formwork assembly, and thus improve the processing quality of the concrete wall.

[0012] In the above-mentioned concrete retaining wall steel formwork assembly, the main board is an integrated structure. The integrated structure has high firmness and good stability.

[0013] In the above-mentioned concrete retaining wall steel formwork assembly, the retaining wall steel formwork assembly also includes a side plate in the shape of a long strip, and both sides of the side plate have a plurality of second connection holes arranged at intervals, and fasteners pass through the second connection holes and the first connection holes to respectively connect the two sides of the side plate to the main plate at the end. The setting of the side plate can seal the end of the steel formwork assembly, so that the steel formwork assembly can form a closed mold cavity, so that concrete will not overflow and can be better formed.

[0014] In the above-mentioned concrete retaining wall steel formwork assembly, the side plates are made of steel material. This structure makes the side plates strong, increases the service life of the formwork, and improves the processing quality of the concrete wall.

[0015] Compared with the prior art, the concrete retaining wall steel formwork assembly provided by the utility model has the following advantages:

[0016] 1. The main board and side boards of this steel formwork assembly are made of steel materials. The main board and side boards are integrated into one by tension rods and fasteners, so that the steel formwork assembly is not easy to deform and damage, thereby increasing the service life of the steel formwork assembly and improving the processing quality of the concrete wall.
