Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a column concrete blocking device and a construction method thereof. Background Art

[0002] Among the house structures currently under construction, concrete structure is the most widely used structural form. In concrete structure, the force mode and force magnitude of columns and beams are different, and the strength requirements of the structure are also inconsistent. In order to ensure the safety of concrete structures and reduce project costs, when designing concrete structures, columns are usually made of high-grade concrete and beams are made of low-grade concrete. Therefore, when pouring concrete, there will be an interface with different concrete grades at the intersection of the column head and the beam. In the past, fine wire mesh was set at the interface to prevent the column concrete from flowing toward the beam. Due to the low strength of the wire mesh, the concrete will flow along the direction of the beam, and form an inclined surface after the beam is poured, resulting in an increase in the amount of high-grade concrete.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0035] The column concrete blocking device provided in the present invention refers to Figure 1-Figure 4 ,include

[0036] Support member 1, which is consistent with the length direction of the beam and has an adjustable length;

[0037] A plurality of fixing sleeves 2, which are sleeved on the supporting member 1, and a plurality of fixing sleeves 2 are arranged along a direction consistent with the length direction of the beam; and

[0038] A plurality of blocking blades 3 are rotatably connected to the corresponding fixed sleeves 2 through a rotating device 4, respectively, allowing the blocking blades 3 to rotate around the central axis of the rotating device 4 to ensure that the width direction of the blocking blades 3 is always perpendicular to the beam axis; and a fixed shaft 5 is installed on the rotating device 4, and a groove 20 adapted to the fixed shaft 5 is configured on one side of the fixed sleeve 2. When the blocking blades 3 are adjusted to the specified position, the blocking blades 3 are fixed by the grooves 20 to prevent the blocking blades 3 from shifting during concrete pouring.

[0039] Specifically, before the concrete pouring construction, the position of the blocking blade 3 is adjusted according to the structure of the beam and the requirements of the concrete pouring direction. The construction personnel rotate the blocking blade 3 so that the length direction of the blocking blade 3 is always perpendicular to the axis of the beam. For example, when the shape of the beam is an asymmetric structure or the pouring entrance of the concrete is located in a special position, it is necessary to accurately adjust the angle of the blocking blade 3 to ensure the correct distribution of the concrete in the beam. After adjusting the angle of the blocking blade 3, the fixed shaft 5 is inserted into the groove 20 on one side of the fixing sleeve 2 to fix the blocking blade 3. A small fixing buckle can also be added at the opening of the groove 20 to prevent the fixed shaft 5 from coming out due to vibration during the concrete pouring process. Then the support 1 with the adjusted blocking blade 3 is placed on the steel bar of the beam, and the support 1 is tied to the steel bar of the beam using its own structural characteristics (such as the tying points or hooks on the support 1). When tying, a tying material with sufficient strength, such as high-strength steel wire, should be used, and the operation should be carried out in accordance with certain tying specifications. When the lateral pressure of concrete acts on the blocking blade 3, the blocking blade 3 transfers the force to the fixing sleeve 2 through the rotating device 4, and the fixing sleeve 2 then transfers the force to the support member 1, and finally to the steel bars of the beam. In this force transmission process, the connection parts between the various components need to ensure effective force transmission. And the design of the column concrete blocking device makes it highly versatile and reusable.

[0040] The blocking blades 3 can rotate around the central axis at an angle of 0-90°. At 0°, the multiple blocking blades 3 can be folded for easy storage. When at 90°, the length direction of the blocking blades 3 is perpendicular to the axis of the beam, which can guide the concrete to flow to the area that needs to be filled and prevent the concrete from flowing into unnecessary areas, thereby ensuring the pouring quality of concrete in these complex structural parts.

[0041] The blocking blade 3 includes a first steel plate 31, a second steel plate 32 and an adjusting bolt 33. The first steel plate 31 is provided with a bolt hole, the second steel plate 32 is provided with a strip hole 30, and the adjusting bolt 33 is fixedly connected to the bolt hole and the strip hole 30. The length of the blocking blade 3 can be adjusted according to actual needs. In the concrete pouring scene, the heights of different beams may be different. By adjusting the position of the adjusting bolt 33 in the strip hole 30, the relative position of the first steel plate 31 and the second steel plate 32 can be changed, thereby achieving the matching of the length of the blocking blade 3 and the height of the beam.

[0042] Reference Figure 1-Figure 3 The adjusting bolt 33 is a high-strength bolt, and a knob is provided on its head for easy operation. This facilitates the construction personnel to quickly and easily adjust the length of the blocking blade 3 at the construction site. For example, when the beam height is high, the construction personnel only need to rotate the knob to move the adjusting bolt 33 in the long hole 30 to lengthen the blocking blade 3. The use of high-strength bolts ensures the stability of the blocking blade 3 structure when subjected to the concrete side pressure, and prevents the bolts from breaking or loosening.

[0043] The surface of the barrier blade 3 is coated with an anti-stick coating, which can effectively prevent concrete from adhering to the surface of the barrier blade 3 during the pouring process. When pouring concrete, the concrete has a certain viscosity, and if there is no anti-stick coating, it is easy to adhere to the surface of the barrier blade 3. The anti-stick coating can effectively prevent this from happening, so that the barrier blade 3 can be easily removed after the concrete solidifies, and at the same time, it also reduces the damage to the barrier blade 3 that may be caused by concrete adhesion, and prolongs the service life of the barrier blade 3.

[0044] Reference Figure 1 The support member 1 includes a support frame for facilitating the binding of the blocking blade 3 to the steel bars of the beam. In construction, the steel bars of the beam are the skeleton of the concrete structure, and firmly binding the blocking blade 3 to the steel bars is the key to ensuring the normal operation of the column concrete blocking device. The design of the support frame should take into account the convenience of binding with the steel bars. For example, the support frame can be provided with specific binding points or hook structures, so that construction workers can use binding materials such as steel wire to quickly and firmly bind it to the steel bars.

[0045] The support frame is made of high-strength aluminum alloy, which has a high strength-to-weight ratio. It can withstand the pressure of concrete pouring without adding too much weight to the entire device, making it convenient for construction workers to carry and install. Secondly, aluminum alloy has good corrosion resistance. In the complex environment of the construction site (such as humidity, corrosive substances, etc.), it can maintain the stability of the structure and extend the service life of the support frame.

[0046] The inner wall of the fixing sleeve 2 is provided with anti-skid patterns, the main purpose of which is to increase the friction between the fixing sleeve 2 and the support 1, and prevent the fixing sleeve 2 from sliding along the support 1 during use. During the concrete pouring process, the fixing sleeve 2 will be subjected to the concrete side pressure transmitted by the blocking blade 3. If the fixing sleeve 2 slides, it will affect the position stability of the blocking blade 3, and further affect the pouring quality of the concrete. The existence of the anti-skid pattern effectively solves this problem. It increases the friction force, firmly fixes the fixing sleeve 2 on the support 1, and ensures the structural stability of the entire column concrete blocking device.

[0047] The rotating device 4 includes a rotating shaft 41, a bearing and a sleeve 42. The rotating shaft 41 passes through the sleeve 42 and is connected to the fixed sleeve 2. The bearing is sleeved on the rotating shaft 41. The sleeve 42 is fixedly connected to the blocking blade 3, so that the blocking blade 3 can rotate flexibly around the rotating shaft 41. In addition, a rotating handle 43 is also provided on the outside of the sleeve 42, which can further facilitate the adjustment of the angle. When the concrete pouring direction needs to be adjusted, the blocking blade 3 is rotated around the rotating shaft 41 by an external force, and the bearing plays a key role in it. The bearing can reduce the friction during the rotation process, making the rotation of the blocking blade 3 smoother, and ensuring that the blocking blade 3 can rotate freely within the range of 0-90°. At the same time, the sleeve 42 connects the blocking blade 3 with the rotating shaft 41, ensuring the transmission of force, so that the blocking blade 3 can stably withstand the lateral pressure of the concrete during the rotation process.

[0048] Reference Figure 1-Figure 4 The construction method of the column concrete blocking device provided by the present invention comprises the following steps:

[0049] Step 1: Adjust the length of the blocking blade 3 according to the beam height so that the blocking blade 3 matches the beam height; the beam height may vary in different building structures, and the blocking blade 3 needs to match the beam height to completely block the flow of concrete in the beam; if the blocking blade 3 is too short, the concrete may overflow from under the blocking blade 3; if it is too long, it may affect other construction processes or cause material waste; since the blocking blade 3 is composed of a first steel plate 31, a second steel plate 32 and an adjusting bolt 33, the length of the blocking blade 3 is changed by adjusting the position of the bolt 33 in the long hole 30 of the second steel plate 32; during the specific operation, the construction personnel need to rotate the knob at the head of the adjusting bolt 33 according to the measured data of the beam height to make the first steel plate 31 and the second steel plate 32 move relative to each other until the length of the blocking blade 3 matches the beam height;

[0050] Step 2: Place the blocking blade 3 on the column head and adjust it to a vertical state; the construction personnel can use tools such as a level or a plumb line to check and adjust the verticality of the blocking blade 3. If the blocking blade 3 is found to be not vertical, it can be adjusted to a vertical state by fine-tuning the position of the blocking blade 3 or the angle of the support 1;

[0051] Step 3: Rotate the blocking blade 3 to 90° so that the length direction of the blocking blade 3 is perpendicular to the beam axis and fix it, so as to most effectively block the flow of concrete in the width direction of the beam, ensure that the concrete is distributed in the beam according to the design requirements, and thus ensure the shape and structural strength of the beam; after the blocking blade 3 is rotated to 90°, it is necessary to perform a fixing operation, and use the groove 20 on one side of the rotating device 4 and the fixed shaft 5 (or other fixing devices) to fix the blocking blade 3. The fixing process must be ensured to be firm to prevent the blocking blade 3 from rotating or shifting due to the lateral force of the concrete during the concrete pouring process. For example, after the fixed shaft 5 is inserted into the groove 20, check whether the fit between the fixed shaft 5 and the groove 20 is tight. If necessary, some auxiliary fixing measures can be added, such as setting a retaining ring at the mouth of the groove 20;

[0052] Step 4: Use iron wire to bind the support 1 to the beam reinforcement and place a fine wire mesh; during the binding process, select iron wire of appropriate specifications and perform the operation according to a certain binding method; for example, a cross binding method can be used. At the same time, pay attention to the uniform spacing of the binding to avoid partial looseness or tightness;

[0053] Step 5. After confirming that the device and the fine wire mesh are properly installed, pour concrete; placing the fine wire mesh can further enhance the crack resistance and integrity of the concrete. When placing the wire mesh, ensure that the wire mesh is laid flatly in the area between the blocking blade 3 and the beam reinforcement. The specifications of the wire mesh should be selected according to the structural requirements of the beam, such as the diameter of the wire, the size of the mesh, etc. For example, for some beams that bear a large load, a wire mesh with a larger wire diameter and a smaller mesh can be selected to improve its crack resistance and reinforcement effect;

[0054] Step 6: When the concrete reaches a certain strength, remove and fold the device to complete the pouring of the column head concrete.

[0055] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
