Description

Technical Field

[0001] This utility model belongs to the field of concrete pouring technology, and in particular relates to a steel formwork for a concrete pouring port with a guide channel. Background Technology

[0002] A concrete pouring spout is used during the concrete pouring process to control the flow and landing point of concrete, ensuring that the concrete is evenly distributed in key areas of the designated pouring area. This guarantees that the concrete is accurately poured into specific locations within the formwork according to construction requirements, preventing the concrete from flowing randomly and thus ensuring the forming quality of the concrete component.

[0003] During concrete construction, concrete pouring ports generally lack effective flow guiding devices. When concrete flows out of the pouring port, the flow direction is difficult to control precisely, which easily leads to concrete accumulating in a single area. This makes it difficult for construction workers to carry out subsequent transfer and paving. In addition, some material transfer ports are too close to the building facade of the lower level due to design problems, causing concrete to accumulate on the wall. Therefore, it is necessary to provide a steel formwork for concrete pouring ports with flow guiding channels to add a flow guiding structure to the pouring position, which can change the pouring direction and achieve the purpose of three-directional material feeding from the left, right and middle sides. Utility Model Content

[0004] The purpose of this utility model is to provide a steel formwork for a concrete pouring port with a guide channel, which adds a guide structure to the pouring position and can change the pouring direction, thereby achieving the purpose of three-directional feeding of pouring from the left, right and middle sides, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A concrete pouring port steel formwork with a guide channel includes a pouring steel channel that is engaged in the inner cavity of the material transfer port; a guide steel channel is provided below the pouring steel channel; lifting screws are welded to both ends of the front and rear sides of the pouring steel channel; a fixing plate is welded to both ends of the front and rear sides of the guide steel channel; an arc-shaped groove adapted to the lifting screw is opened on the right side of the fixing plate; a pushing component is provided at the bottom of the surface of the lifting screw; the pushing component includes a positioning sleeve sleeved on the surface of the lifting screw; an extrusion head is fixedly connected to the top of the positioning sleeve; a circular groove communicating with the arc-shaped groove is opened at the bottom of the fixing plate; and the extrusion head is engaged in the inner cavity of the circular groove.

[0006] Preferably, an extrusion plate is fitted onto the surfaces of the two lifting screws on the same side, and nuts threaded onto the surfaces of the lifting screws are provided on the front and rear sides of the bottom of the extrusion plate, and the top and bottom of the extrusion plate are tightly fitted to the wall and the nuts, respectively.

[0007] Preferably, the surface of the positioning sleeve is provided with a movable groove, and the inner cavity of the movable groove is rotatably connected to a threaded rotating sleeve, which is threadedly connected to the surface of the lifting screw.

[0008] Preferably, limiting inserts are welded to both sides of the inner cavity of the positioning sleeve, and limiting grooves adapted to the limiting inserts are provided on both sides of the surface of the hoisting screw.

[0009] Preferably, a handle is welded to the left side of the guide steel channel.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses the combined use of a pouring steel trough and a guiding steel trough to guide and adjust the pouring position of concrete. At the same time, by setting up a propulsion component, the guiding steel trough can be quickly disassembled and its direction adjusted, thereby achieving the purpose of controlling the concrete pouring direction and making the pouring direction adjustable.

[0012] 2. This utility model uses the combination of the extrusion plate and the nut to extrude force on the wall, which in turn stretches the hoisting screw downward, so that the pouring steel trough can be stably installed in the inner cavity of the material inlet, ensuring stability during the concrete pouring process.

[0013] 3. This utility model uses the combination of movable groove and threaded rotating sleeve to adjust the height of positioning sleeve and extrusion head, so that the guide steel channel can be stably positioned below the pouring steel channel to guide the concrete.

[0019] In the following description, embodiments of the steel formwork for concrete pouring inlets with guide channels of the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-4This invention illustrates a concrete pouring port steel formwork with a guide channel according to an embodiment of the present invention. It includes a pouring steel trough 2 that engages within the inner cavity of a material inlet 1. A guide steel trough 3 is positioned below the pouring steel trough 2. A handle 12 is welded to the left side of the guide steel trough 3. Lifting screw rods 4 are welded to both ends of the front and rear sides of the pouring steel trough 2. Extrusion plates 8 are fitted onto the surfaces of the two lifting screw rods 4 on the same side. Nuts 9, threaded onto the surfaces of the lifting screw rods 4, are provided on the front and rear sides of the bottom of the extrusion plates 8. The top and bottom of the extrusion plates 8 are tightly fitted to the wall and the nuts 9, respectively. Through the combined use of the extrusion plates 8 and the nuts 9, an extrusion effect is applied to the wall, thereby exerting a downward stretching effect on the lifting screw rods 4. This ensures that the pouring steel trough 2 can be stably installed within the inner cavity of the material inlet 1, guaranteeing stability during concrete pouring. Fixing plates 5 are welded to both ends of the front and rear sides of the guide steel trough 3. A connection point for the lifting screw rods 4 is provided on the right side of the fixing plates 5. The lifting screw 4 is fitted with an arc-shaped groove 6. A propulsion assembly 7 is provided at the bottom of the surface of the lifting screw 4. The propulsion assembly 7 includes a positioning sleeve 71 sleeved on the surface of the lifting screw 4. Limiting inserts 10 are welded to both sides of the inner cavity of the positioning sleeve 71. Limiting grooves 11 that are adapted to the limiting inserts 10 are opened on both sides of the surface of the lifting screw 4. A movable groove 75 is opened on the surface of the positioning sleeve 71. A threaded rotating sleeve 74 is rotatably connected to the inner cavity of the movable groove 75. The threaded rotating sleeve 74 is threadedly connected to the surface of the lifting screw 4. Through the cooperation of the movable groove 75 and the threaded rotating sleeve 74, the height of the positioning sleeve 71 and the extrusion head 72 is adjusted, so that the guide steel channel 3 can be stably positioned below the pouring steel channel 2 to guide the concrete. The top of the positioning sleeve 71 is fixedly connected to the extrusion head 72. A circular groove 73 that communicates with the arc-shaped groove 6 is opened at the bottom of the fixing plate 5. The extrusion head 72 is engaged in the inner cavity of the circular groove 73.

[0021] Working Principle: When using this utility model, the user first engages the casting steel trough 2 within the inner cavity of the material inlet 1, allowing the lifting screw 4 to pass through to the bottom of the material inlet 1. Then, the user places the extrusion plate 8 onto the surfaces of the two lifting screws 4 on the same side and rotates the nut 9, causing the thread of the nut 9 to rotate upwards. Finally, the nut 9 presses against the bottom of the extrusion plate 8, and the top of the extrusion plate 8 presses against the wall surface, thus fixing the casting steel trough 2 in place. Depending on the user's casting requirements, casting can be done on the left, middle, or right side. Casting on the left or right sides can be achieved by adjusting the discharge direction of the guide steel trough 3. Middle casting does not require assembly of the guide steel trough 3. When installing the guide steel trough 3, the user moves it from one side to the other. The horizontal advancement causes the four arc-shaped slots 6 to be respectively fitted onto the surfaces of the four lifting screws 4. Then, the user releases the guide steel channel 3, causing it to fall and drive the circular slot 73 to engage with the surface of the extrusion head 72. The user then rotates the threaded sleeve 74. During the rotation, the threaded sleeve 74 is displaced upward due to its threaded connection with the lifting screw 4. At the same time, it causes the positioning sleeve 71 and the extrusion head 72 to move upward, extruding the guide steel channel 3 and thus ensuring that the guide steel channel 3 is securely installed. Finally, the concrete is poured into the inner cavity of the pouring steel channel 2 by the pouring machine. The concrete entering the inner cavity of the pouring steel channel 2 then enters the inner cavity of the guide steel channel 3 and is transported to the designated direction under the guiding action of the guide steel channel 3.

[0022] In summary, this concrete pouring port steel formwork with a guide channel, through the combined use of the pouring steel channel 2 and the guide steel channel 3, guides and adjusts the pouring position of the concrete. At the same time, by setting the propulsion component 7, the guide steel channel 3 can be quickly disassembled and its direction adjusted, thereby achieving the purpose of controlling the concrete pouring direction and making the pouring direction adjustable.
