Description

Insertion height control device for side-pouring concrete in steel-concrete composite columns Technical Field

[0001] This utility model relates to the field of concrete construction technology in building engineering, specifically an insert-type height control device for pouring concrete on the side of a steel-concrete composite column. Background Technology

[0002] According to the requirements of the National Building Standard Design Atlas 16G519 "Detailed Construction Drawings of Steel Structure Nodes in Multi-Story and High-Rise Civil Buildings", concrete pouring on the inner side of steel-concrete composite columns such as box-section columns and circular steel pipe columns is carried out by opening holes on the column side, with a hole diameter of ∅150. In traditional construction, due to space constraints, multiple people are needed to operate the pump pipe connection during pouring, which is time-consuming and labor-intensive, and results in significant concrete spillage and resource waste. A better approach is to weld a connecting steel pipe to the outside of the pouring hole, which then connects to the concrete pouring pump pipe for pouring. This saves manpower and reduces concrete spillage. However, after the concrete is poured, the connecting steel pipe needs to be cut off, and the area around the pouring hole needs to be ground and repaired. This welding and cutting repair of the connecting steel pipe has a significant impact on the structure of the steel column itself, affecting its stiffness and strength. Moreover, the quality requirements for welding and cutting repair are high, the operation is cumbersome, and it is time-consuming, labor-intensive, and material-intensive. Summary of the Invention

[0019] As shown in Figures 1-4, this embodiment provides an insert-type height control device for side-pouring concrete in steel-concrete composite columns, including a galvanized steel guide pipe 1, a stainless steel receiving port 2, an angle steel support frame 3, an alarm device box 4, a connecting steel pipe 5, a float rod locking component 6, a float rod 7, a float valve 8, a contact sensor 9, and a rotating shaft 14.

[0020] The guide galvanized steel pipe 1 adopts a zigzag-shaped pipe body, which includes an upper vertical pipe and a lower inclined pipe. The top end of the guide galvanized steel pipe 1 is fixedly installed at the outlet below the stainless steel plate receiving port 2, and the bottom end of the guide galvanized steel pipe 1 is movably inserted into the injection port of the steel column. The angle steel support frame 3 is located on both sides of the guide galvanized steel pipe 1 and is fixedly installed on the stainless steel plate receiving port 2. The alarm device box 4 is fixedly installed on the guide galvanized steel pipe 1. The connecting steel pipe 5 is fixedly installed inside the guide galvanized steel pipe 1 at the upper part, and the upper end is aligned with the position of the alarm device box 4. The float rod locking piece 6 is fixedly installed at the lower end of the connecting steel pipe 5. One end of the float rod 7 is located inside the float rod locking piece 6 and is rotatably connected to the float rod locking piece 6 through the rotating shaft 14. The other end of the float rod 7 is fixedly installed on the float valve 8. The contact sensor 9 is fixedly installed at the upper part of the front end hole of the float rod locking piece 6 and is electrically connected to the alarm device box 4.

[0021] In this embodiment, an annular bonding plate 10 is fixedly installed on the inclined tube of the guide galvanized steel pipe 1 near the bottom pipe opening; each side of the annular bonding plate 10 is 30mm larger than the side of the guide galvanized steel pipe 1, and is firmly bonded to the surface of the steel column to ensure that the device is stable and reliable when concrete is poured.

[0022] In this embodiment, the stainless steel plate receiving port 2 is provided with three handles 11.

[0023] In this embodiment, the angle steel support frame 3 includes vertical angle steel sections and horizontal angle steel sections connected at right angles to form a stable triangular skeleton; the vertical angle steel sections of the two angle steel support frames 3 are located on both sides of the guide galvanized steel pipe 1 and their top ends are connected and fixed to the stainless steel plate receiving port 2; a square bearing plate 12 is welded and fixed between the ends of the horizontal angle steel sections of the two angle steel support frames 3. When the grouting device is placed, the square bearing plate 12 is firmly attached to the outer surface of the steel column to bear the lower component force of the grouting device.

[0024] In this embodiment, a square pad steel plate 13 is provided on the float rod locking component 6. The square pad steel plate 13 is fixedly installed at the lower part of the front end hole of the float rod locking component 6. The square pad steel plate 13 supports the float rod 7, thereby raising the float valve 8 at the other end of the float rod 7 to a certain height. In this way, the float valve 8 can avoid the impact of concrete entering from the injection port to a certain extent, protecting the float valve 8 from damage.

[0025] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0026] In this embodiment, the manufacturing process and usage method of the insert-type height control device for pouring concrete on the side of the steel-concrete column are as follows:

[0027] 1. Fabrication of the outer frame of this device:

[0028] The main body of this device is welded together from a square stainless steel plate receiving port 2 and a zigzag galvanized steel guide pipe 1.

[0029] The stainless steel receiving port 2 is made of 5mm thick stainless steel plate, shaped like a funnel with a top and bottom round shape. The upper part has a 500×500mm square opening, and the lower part has a 150mm diameter round hole that is butt-welded to the guide galvanized steel pipe 1. To avoid the protruding connecting lugs on the steel column, the side of the stainless steel receiving port 2 is kept at least 200mm away from the side of the steel column.

[0030] The guide galvanized steel pipe 1 consists of two sections of 150mm diameter steel pipe butt-welded at a 120° angle to ensure the fluidity of the concrete. The vertical pipe is 200mm long and is butt-welded to the lower round hole of the stainless steel receiving port 2. The inclined pipe is 650mm long and its end extends 100mm into the pouring port.

[0031] A 10mm thick steel plate is installed 200mm below the insertion port of the galvanized steel pipe 1 as an annular bonding plate 10, with each side being 30mm larger than the side of the galvanized steel pipe 1. It is firmly attached to the surface of the steel column to ensure the stability and reliability of the device when concrete is poured. A 50×50×5mm vertical angle steel section with a length of 660mm is welded to each side of the galvanized steel pipe 1 below the stainless steel plate receiving port 2. It is connected to a horizontal angle steel section with a length of 480mm to form an angle steel support frame 3. A 5mm thick square load-bearing plate 12 with a B*H=300*150mm is installed below the insertion port of the galvanized steel pipe 1. It is welded to the horizontal angle steel section of the angle steel support frame 3 to form a stable triangular skeleton. When the grouting device is placed, it firmly supports the outer surface of the steel column and bears the lower component force of the grouting device.

[0032] 2. Fabrication of internal parts of this device:

[0033] The internal components of this device consist of a float device located above the end guide galvanized steel pipe 1 and an alarm device box 4 fixed on the guide galvanized steel pipe 1. The two are connected by welding a DN40 connecting steel pipe 5 inside the guide galvanized steel pipe 1.

[0034] The float assembly is welded to the end of the connecting steel pipe 5 and consists of a square float rod holder 6 made of 5mm steel plate, an 8mm diameter float rod 7, and a 100mm diameter float valve 8. The holder 6 has a locking hole size of B*H=10*25mm, which allows for free vertical displacement of the float rod 7. Holes with a diameter of 12mm are drilled on both sides of the tail end of the holder 6, and a 10mm diameter pin is inserted and fixed as a rotating shaft 14. The tail end of the float rod 7 is welded to the pin.

[0035] To reduce the impact of concrete entering the grouting port on the float valve 8, a square pad steel plate 13 is installed at the lower part of the front end orifice of the float rod locking component 6, and the float rod 7 is installed in the upper part of the square pad steel plate 13. A contact sensor 9 is installed at the upper part of the front end orifice of the float rod locking component 6. When the concrete grouting liquid surface presses against the float valve 8, the float rod 7 makes contact with the contact sensor 9 and triggers an alarm. The alarm device box 4 provides an audible and visual alarm message to prompt the construction personnel to stop grouting.

[0036] The alarm device box 4 contains a power supply component and alarm electronic components. The power supply component is powered by two AA batteries, and the alarm components include sound and flashing functions. The power supply component is connected to the alarm electronic components, and the alarm device box 4 is connected to the contact sensor 9 using 2*1.5mm² wires.

[0037] 3. Concrete pouring on the side of the column:

[0038] Before construction, check and verify the diameter of the concrete pouring hole, and clean away any debris around the hole. The concrete inside the column is self-compacting concrete, requiring no vibration. Before pouring, position the pump truck and insert this device directly into the concrete pouring hole. The handle 11 on the stainless steel receiving port 2 facilitates movement of the device by construction personnel. After the annular bonding plate 10 is firmly attached to the surface of the steel column, concrete pouring operations can begin. During pouring, a designated person is responsible for loading concrete from the concrete mixer truck to ensure stable and continuous concrete pumping.

[0039] As concrete is poured, the float valve 8 rises with the concrete level. When the concrete level reaches the design elevation, the float rod 7 touches the contact sensor 9 at the upper end of the float rod locking piece 6. At this time, the contact sensor 9 transmits a signal to the alarm device box 4, generating an audible and visual alarm. When the operator sees the alarm signal, they should stop pouring immediately, remove the device, and check that the pouring height and density of the concrete inside the column meet the design requirements. Then, move the device to the next steel column pouring hole and repeat the above steps until all the concrete inside the steel columns is poured.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
