Description

Technical Field

[0001] This utility model belongs to the technical field of retaining wall steel formwork, and relates to a concrete feeding structure for slope retaining wall steel formwork. Background Technology

[0002] Retaining wall steel formwork is a type of steel mold used in building construction, primarily providing temporary support structures and forming space for concrete retaining walls. Made of steel, it features high strength, durability, and easy disassembly, and can be assembled according to project needs to adapt to the construction requirements of retaining walls of varying heights and lengths.

[0003] Existing retaining wall steel formwork, such as the concrete retaining wall steel formwork assembly disclosed in Chinese patent literature [Patent No.: 202420744286.3; Application Publication No.: CN222161971U], includes at least one pair of opposing main plates and several tension rods. The main plates are made of steel, and several fixing strips are spaced apart on the outer side wall of the main plates. Fixing grooves are formed in the fixing strips, and several fixing holes are spaced apart at the bottom of the fixing grooves. The tension rods are located between the opposing main plates, and both ends of the tension rods pass through the fixing holes and fixing grooves. Fasteners are fitted onto both ends of the tension rods and abut against the fixing strips, so that the main plates and tension rods are integrated into one unit. Connecting strips are provided at both ends of the main plates, and the connecting strips have several first connecting holes. Two adjacent main plates on the same side are locked together by fasteners passing through the first connecting holes.

[0004] This type of retaining wall steel formwork assembly involves mixing concrete first using a mixer, then pouring the mixed concrete into a funnel. A crane then lifts the funnel, and the baffle at the funnel's outlet is opened, allowing the concrete to flow into the mold cavity inside the retaining wall steel formwork assembly. Once the concrete has solidified, the wall is formed. However, while this type of retaining wall steel formwork assembly is used for vertical walls, when the wall has a large angle of inclination, the distance between the funnel and the crane becomes greater, requiring the use of a long-arm, high-tonnage crane, increasing costs. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a concrete feeding structure for steel formwork of a slope retaining wall. The technical problem solved is how to make concrete feeding convenient and reduce costs.

[0006] The objective of this utility model can be achieved through the following technical solution: a concrete feeding structure for a steel formwork of a slope retaining wall, the steel formwork of the retaining wall including a back plate, a front plate and side plates located at both ends, the back plate, the front plate and the side plates forming a mold cavity for pouring concrete, the front plate being inclined forward and downward along the direction of the back plate toward the front plate, characterized in that the feeding structure includes a feeding trough and a support frame, the bottom of the support frame being fixedly connected to the front plate, the top of the support frame being fixedly connected to the feeding trough, the feeding trough being inclined forward and upward along the direction of the back plate toward the front plate, the discharge end of the feeding trough being located directly above the mold cavity, and the inlet end of the feeding trough being located outside the bottom end of the front plate along the direction of the back plate toward the front plate.

[0007] In operation, concrete is mixed using a mixer, then poured into a funnel. A crane lifts the funnel, and the baffle at the funnel's outlet is opened, allowing the concrete to flow into a feeding chute. The concrete flows along the feeding chute into the mold cavity, facilitating concrete feeding. After solidification, the concrete forms a retaining wall. The discharge end of the feeding chute is located directly above the mold cavity, while the inlet end is located outside the bottom of the panel along the direction from the back plate towards the panel. This feeding chute design compensates for the panel's forward and downward tilt along the direction from the back plate towards the panel, allowing for a shorter crane boom and a smaller crane tonnage, reducing crane operating costs and thus lowering the construction cost of the sloping retaining wall. In suitable locations, the mixed concrete can be directly poured into the feeding end of the feeding chute, allowing for direct pouring into the mold cavity, further reducing costs. A support frame provides support, ensuring the feeding chute is fixed in a suitable position.

[0008] In the aforementioned concrete feeding structure for a slope retaining wall using steel formwork, several horizontally arranged first reinforcing rods are fixedly connected at intervals on the panel. The support frame is arranged in an "I" shape, with its bottom ends located at the top and bottom of the panel. The bottom ends of the support frames abut against the first reinforcing rods and are locked with bolts. The top end of the support frame is located near the feed end of the feeding trough. The first reinforcing rods improve the strength of the panel, the "I" shape of the support frame provides better support and improves the stability of the feeding trough, and the bottom ends of the support frames abut against the first reinforcing rods and are locked with bolts, allowing the support frame to be disassembled for convenient storage and transportation.

[0009] In the above-described concrete feeding structure for a steel formwork of a slope retaining wall, there are two support frames, which are symmetrically arranged on both sides of the feeding trough. This structure improves the stability of the feeding trough and ensures that concrete can be fed normally into the formwork cavity.

[0010] In the aforementioned concrete feeding structure for a steel formwork of a slope retaining wall, both side walls of the feeding trough opening are bent outwards to form flanges. This structure improves the stability of the feeding trough and ensures that concrete can be fed normally into the formwork cavity.

[0011] In the aforementioned concrete feeding structure for a slope retaining wall using steel formwork, the angle between the feeding trough and the horizontal plane is between 15° and 30°. This structure ensures that the concrete can slide while keeping the height of the feeding end of the trough as low as possible, making concrete feeding convenient.

[0012] In the aforementioned steel formwork concrete feeding structure for a slope retaining wall, several second reinforcing rods are fixedly connected at intervals on the panel. These second reinforcing rods are inclined forward and downward along the direction from the back plate towards the panel. The first and second reinforcing rods are staggered and perpendicular to each other, and both are attached to the panel. The second reinforcing rods, in conjunction with the first reinforcing rods, enhance the strength of the panel.

[0013] In the aforementioned concrete feeding structure for a slope retaining wall using steel formwork, the back plate is vertically oriented, and several third reinforcing rods arranged horizontally and several fourth reinforcing rods arranged vertically are fixedly connected at intervals on the back plate. The third and fourth reinforcing rods are staggered and perpendicular to each other, and both are attached to the back plate. The third and fourth reinforcing rods work together to enhance the strength of the back plate.

[0014] In the aforementioned concrete feeding structure for a slope retaining wall steel formwork, the top edge of the panel has a forward-extending, horizontally oriented first reinforcing plate. Several first reinforcing columns are spaced apart between the front end of the first reinforcing plate and the panel, and these columns are vertically aligned. The discharge end of the feeding chute rests against the first reinforcing plate. This structure enhances the strength of the top of the panel, thereby increasing the strength of the retaining wall steel formwork. Simultaneously, the operator can stand on the first reinforcing plate to observe and ensure the concrete is fed in place.

[0015] In the aforementioned concrete feeding structure for a slope retaining wall steel formwork, the top edge of the back plate has a rearward-extending, horizontally oriented second reinforcing plate. Several second reinforcing columns are spaced apart between the rear end of the second reinforcing plate and the back plate, and these columns are inclined forward and downward along the direction from the back plate towards the front panel. This structure enhances the strength of the top of the back plate, thereby increasing the strength of the retaining wall steel formwork. Simultaneously, the operator can stand on the first reinforcing plate to observe and ensure the concrete is fed in place.

[0016] In the aforementioned concrete feeding structure for a slope retaining wall steel formwork, several vertically arranged reinforcing strips are fixedly connected to the side plate. A horizontally arranged placement frame is fixedly connected to the bottom of each reinforcing strip, and the outer end of the placement frame is connected to the reinforcing strip via a tie rod. The reinforcing strips enhance the strength of the side plate, thereby increasing the strength of the retaining wall steel formwork. If necessary, counterweights can be placed on the placement frame to prevent the retaining wall steel formwork from being lifted.

[0017] Compared with the prior art, the concrete feeding structure of the steel formwork for the slope retaining wall provided by this utility model compensates for the amount of the panel being inclined forward and downward along the direction of the back plate towards the panel by setting the feeding trough, so that the boom of the crane can be relatively short and the tonnage of the crane can be relatively small, thereby reducing the operating cost of the crane and thus reducing the construction cost of the slope retaining wall.
