Description

Technical Field

[0001] This invention relates to the field of concrete equipment, and in particular to a small-component concrete placement device that integrates mixing, excavation, and transportation. Background Technology

[0002] In the construction industry, there are many small cast-in-place reinforced concrete components, such as structural columns, door and window lintels, etc. Due to their small structural size, the high height of the concrete inlet, the small volume of concrete, and the special distribution of the components in the building, the construction is quite difficult, especially the difficulty of pouring the concrete into the formwork.

[0003] In existing technologies, shovels are used to secondary mix, excavate, transport, and pour cement concrete into the formwork of small cast-in-place reinforced concrete components such as columns, door and window lintels, to achieve cement concrete pouring construction. However, currently, the amount of cement concrete excavated by shovels is small at a time, and cement concrete is prone to falling off the shovel, resulting in material waste. At the same time, there are also problems of slow construction speed and low efficiency. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a small-component concrete placement device that integrates mixing, excavation, and transportation. This device enables secondary mixing, excavation, and transportation of concrete, addressing the issues of small-sized components and limited concrete volume requiring manual placement, which is difficult and challenging, especially for structural columns where the concrete inlet is located at the top and at a considerable height. It also solves the problems of small quantities of concrete being excavated with shovels, easy spillage, material waste, slow construction speed, and low efficiency. This device not only improves construction efficiency but also increases worker comfort. Furthermore, this integrated small-component concrete placement device is simple in structure, easy to manufacture, economical, and has a long service life.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A small-component concrete placement device that integrates mixing, excavation, and transportation includes a main body. A rigid handle is detachably installed on the back of the main body via a fastener. A handle structure is arranged at the upper end of the main body, and the two ends of the handle structure are connected to the main body via flexible handles.

[0006] The main body includes a base plate, and the upper part of the base plate, together with the left and right side plates and the rear plate at the rear end, forms a concrete receiving cavity.

[0007] The top of the side panel has a zigzag shape, with the front lower than the back.

[0008] The rear plate is 8 mm - 12 mm wider on the left and right sides than the front end of the main body.

[0009] The base plate, side plates, and rear plate are made by bending a single piece of stainless steel sheet.

[0010] The flexible handle is made of steel wire rope.

[0011] The flexible handle freely passes through the handle hole on the side plate and is welded and fixed to the handle head.

[0012] The flexible handle cover is equipped with a flexible hose sheath.

[0013] The rigid handle and carrying handle structures are both made of U-shaped rust-proof metal components.

[0014] The fastening component is a rust-proof bolt.

[0015] This invention provides a small-component concrete placement device that integrates mixing, excavation, and transportation, and has the following technical advantages: 1) By designing the plate of the small-component concrete formwork device that integrates mixing, excavation, and transportation into a narrow front and wide back, and low front and high back, it is convenient to remix, excavate, transport, and pour the concrete into the formwork. To a certain extent, it restricts the excavated concrete, reduces the risk of concrete flowing out, and realizes the effective excavation and transportation of concrete into the formwork. It solves the problem that concrete easily falls off the shovel after being excavated by shovel, and reduces waste in the process of using concrete.

[0016] 2) By using rigid handles and flexible lifting handles, the operator's hand movements are more coordinated and precise, resulting in higher efficiency and more obvious effects, and in particular, greater comfort. One hand holds the rigid handle and the other holds the flexible lifting handle, and the force applied to the device is used to complete operations such as secondary mixing, excavation, transportation, and pouring of concrete into the formwork.

[0017] 3) By installing a flexible hose sheath on the flexible handle, the hand can be effectively protected. Using rust-proof bolts as fasteners makes it easy to connect and disassemble the rigid handle to the plate, which is beneficial for equipment maintenance. Attached Figure Description

[0020] Figure 3 for Figure 1 The sectional view at point A in the diagram.

[0021] Figure 4 for Figure 1 The sectional view at point B in the diagram.

[0022] In the diagram: body 1, bottom plate 11, side plate 12, rear plate 13, rigid handle 2, handle structure 3, flexible handle 31, flexible hose sheath 32, handle head 33, fastener 4, handle perforation 5. Detailed Implementation

[0023] like Figure 1-4 As shown, a small component concrete placement device integrating mixing, excavation, and transportation includes a main body 1, a rigid handle 2 on the back of the main body 1, and a lifting handle structure 3 on the upper end of the main body 1.

[0024] The main body 1 is formed by a base plate 11, left and right side plates 12 and a rear plate 13. The main body 1 is 320mm long, 130mm high and 220mm wide at the rear end, and 40mm high and 180mm wide at the open end. That is, it is low in the front and high in the back, narrow in the front and wide in the back. It is used for mixing, excavating and transporting concrete.

[0025] The rigid handle 2 is detachably connected to the rear plate 13 of the body 1 via the fastener 4 and remains in a horizontal position.

[0026] The handle structure 3 is similar in appearance to the rigid handle 2, both adopting a U-shaped structure. Flexible handles 31 are connected to both ends of the handle structure 3. The corresponding side plate 12 has a handle through hole 5, slightly larger than the diameter of the flexible handle 31, drilled at a distance of 180mm from the rear end and 60mm from the bottom of the plate body 1. The flexible handle 31 passes through the handle through hole 5 and is welded to the handle head 33. The handle head 33 acts as a limiter when the handle structure 3 is lifted, preventing the flexible handle 31 from detaching from the body 1.

[0027] The top of the side panel 12 has a zigzag shape, with a lower front and higher rear. The front end is 40mm high, the distance from the front end is 110mm high, and the rear end is 120mm high. This design facilitates the retrieval, storage, and insertion of materials into the formwork of the limited size within a confined space, reducing material waste, improving construction efficiency, and enhancing the aesthetic appearance.

[0028] The rear plate 13 is 10mm wider than the front sides of the main body 1, and after being bent, it wraps around the side plate 12 and is welded and fixed to the side plate 12. The portion protruding from the side plate is cut off along the top of the rear plate 13 to the top of the side plate 12. This makes the product structure reasonable, aesthetically pleasing, more robust and durable, and safer to use. At the same time, it is relatively economical and convenient to manufacture, not only reducing the unavoidable connection length between the main body components and the investment in secondary processing, but also better meeting the overall conditions of reasonable stress and avoiding damage in the use environment.

[0029] The base plate 11, side plates 12, and rear plate 13 of the main body 1 are formed by bending a single piece of stainless steel sheet cut to the design dimensions, and the edges are lightly polished smooth with a grinder. This minimizes secondary connections between the main body components, effectively increasing the overall integrity, strength, and service life of the structure, and eliminating the potential harm to people and objects caused by burrs from the cut edges.

[0030] The flexible handle 31 is made of 5mm diameter steel wire rope. After installation, the vertical height from the top of the flexible handle 31 to the center of the handle through hole 5 is 110mm.

[0031] The flexible handle 31 is covered with a flexible hose sheath 32. The inner diameter of the flexible hose sheath 32 is slightly smaller than the outer diameter of the flexible handle 31. Its length is such that after it is inserted into the flexible handle 31, both ends are 50mm higher than the top of the side plate 12 at the handle through hole 5.

[0032] The handle head 33 is a square thin metal block with a side length greater than the diameter of the handle hole 5.

[0033] The rigid handle 2 is a rust-proof metal component with rounded edges and corners, 20mm wide and 3mm thick. After the rigid handle 2 is installed, there is a 100×50mm hand grip space between it and the back plate 13.

[0034] Fastener 4 is a rust-proof bolt with a diameter of 6mm and a length of 20mm.

[0035] Working principle and process: When in use, the operator holds the rigid handle 2 with one hand and the flexible handle 3 with the other hand, and uses both hands to work together to mix, dig, transport and pour the concrete into the formwork through the open end of the scoop, thus completing the concrete pouring operation of the small concrete structure.
