Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a method for pouring concrete for densely reinforced corbels. Background Technology

[0002] In existing technologies, the following measures are typically used for concrete pouring in areas with densely reinforced steel corbels:

[0003] 1) Optimize concrete materials: such as using small-diameter coarse aggregates or self-compacting concrete to improve fluidity and filling properties;

[0004] 2) Micro-vibration technology: such as using a φ20~30mm high-frequency immersion vibrator or a manual vibrator to enhance the vibration effect;

[0005] 3) Adjust the spacing of the reinforcing bars: appropriately increase the clear spacing of the reinforcing bars to improve the compactness of the concrete pouring.

[0006] However, these methods have obvious shortcomings:

[0007] 1) Higher cost: Self-compacting concrete, micro-vibration equipment, etc. will increase material and construction costs;

[0008] 2) Quality risks: Sliding bearings may be embedded in the upper part of the corbel, which may prevent concrete from effectively entering the lower part of the bearing or from being vibrated. If the vibration is insufficient, defects such as honeycomb, pitting or loose concrete may appear on the corbel, affecting the durability of the structure.

[0009] Therefore, there is an urgent need for a more economical, efficient and reliable solution that can optimize the concrete pouring quality of densely reinforced corbel sections. Summary of the Invention

[0011] The present invention provides a method for pouring densely reinforced concrete corbels, comprising the following construction steps:

[0012] S1. Erection of corbel formwork for densely reinforced corbels; the end of the corbel formwork is connected to the main building formwork of the building structure;

[0013] The densely reinforced corbel has a pre-embedded support, which is located in the upper part of the corbel template in the height direction.

[0014] The corbel template includes a side template, a detachable pouring box is provided on the side template, an inlet is provided on the side template, an outlet is provided on the pouring box, and a gate is provided between the inlet and the outlet. The gate is driven to connect or block the inlet and the outlet.

[0015] The side formwork with the pouring box includes at least two pieces, one of which is used for pouring concrete into the corbel formwork by the pouring equipment, and the other is used for vibrating the concrete poured into the corbel formwork by the vibrating equipment.

[0016] S2. Open the gate to connect the corbel template of the densely reinforced corbel with at least two pouring boxes; and set the pouring end of the pouring equipment and the vibrating end of the vibrating equipment at their respective preset positions.

[0017] S3. Pour concrete into the main building structure with densely reinforced corbels. Stop grouting after the concrete rises to the vicinity of the densely reinforced corbels within the main building formwork.

[0018] S4. Pour concrete into the densely reinforced corbel; during the pouring process, use a vibrating device to vibrate the concrete poured into the corbel formwork.

[0019] S5. When the poured concrete inside the main building is at or above the height of the densely reinforced corbel, the concrete pouring inside the corbel formwork is completed.

[0020] S6. Remove the pouring end of the pouring equipment and the vibrating end of the vibrating equipment from their respective preset positions, and close the gate to close the corbel formwork of the densely reinforced corbel.

[0021] S7. After recovering the excess concrete in the pouring box, dismantle the pouring box.

[0022] Furthermore, the side template has a limiting element for limiting the position of the gate.

[0023] Furthermore, the limiting member has a pre-tightening force to clamp and limit the gate plate. In use, the gate plate is sealed by the pre-tightening force applied by the limiting member to the feed port opened on the side template.

[0024] Furthermore, the top of the grouting box is open and is not lower than the height of the densely reinforced steel corbel.

[0025] Furthermore, the support serves as the top mold of the corbel template.

[0026] Furthermore, the two side templates are arranged opposite each other.

[0027] Furthermore, the pouring box is equipped with a discharge port that can be controlled to open and close.

[0028] Furthermore, the pouring box has a guide surface that is inclined toward the discharge port.

[0029] Furthermore, the inner end, outer end, and top of the filling box are all open;

[0030] The outer side of the filling box is provided with an outer side plate that slopes inward from top to bottom, and the outer side plate is controlled to open or close the outer opening of the filling box.

[0031] Furthermore, the limiting member has a fixed end and a free end. When in use, the fixed end is set on the side template, and the free end is applied with a pre-tightening force to adhere to the side template. When in use, the gate is pressed against the side template by the free end of the limiting member.

[0040] Figures 1-6 As shown in the figure, the method for pouring concrete for the densely reinforced corbel in this embodiment includes the following construction steps:

[0041] S1. Erection of corbel formwork for densely reinforced corbels; the end of the corbel formwork is connected to the main building formwork of the building body; the end is the end facing one side of the building, and the opposite end is the beginning end, and the beginning end of the corbel formwork is closed by the end formwork 1.

[0042] In this embodiment, a support 2 is pre-embedded in the densely reinforced corbel. In the height direction, the support 2 is located in the upper part of the corbel formwork. In this solution, the support 2 serves as the top formwork of the corbel formwork, sealing the top of the corbel formwork. The support 2 is used to assemble auxiliary structural components in the building.

[0043] In this embodiment, the corbel template includes a side template 3, a detachable pouring box 4 is provided on the side template 3, an inlet 5 is provided on the side template 3, an outlet 6 is provided on the pouring box 4, and a gate 7 is provided between the inlet 5 and the outlet 6. The gate 7 is driven to connect or block the inlet 5 and the outlet 6.

[0044] In this embodiment, a rectangular feed port 5 is opened at the top of the side template 3, and the side template 3 has a limiting member 8 for limiting the gate plate 7; the limiting member 8 has a pre-tightening force to clamp and limit the gate plate 7. In use, the gate plate 7 is sealed by the pre-tightening force applied by the limiting member 8 to open the feed port 5 on the side template 3.

[0045] Specifically, the limiting member 8 is an elastic steel plate with a certain elasticity. The total height of the elastic steel plate is similar to the height of the side template 3, which improves the limiting ability of the gate plate 7 and enhances the compressive strength of the side template 3. The limiting member 8 has a fixed end and a free end 81. When in use, the fixed end is set on the side template 3, and the free end 81 is subjected to a pre-tightening force and adheres to the side template 3. When in use, the gate plate 7 is pressed against the side template 3 by the free end 81 of the limiting member 8. Along the expansion direction of the corbel in the main building, the side of the elastic steel plate away from the feed inlet 5 is fixed to the side template 3; the side of the elastic steel plate near the feed inlet 5 is the free end 81, which is subjected to pre-tightening force and closely fits the side template 3. The cross-section of the free end 81 of the limiting member 8 is triangular, and a cavity joint is pre-formed to facilitate the insertion of the gate plate 7. The limiting member 8 is set inside the corbel template, and there are two limiting members 8 arranged opposite each other on both sides of the feed inlet 5 along the expansion direction of the corbel in the main building, which improves the guiding and limiting ability of the gate plate 7, so that the gate plate 7 can more reliably seal and close the feed inlet 5.

[0046] In this embodiment, the top of the gate plate 7 has a gate plate 7 handle for easy operation of the gate plate 7, and the bottom of the gate plate 7 has a guide portion 71, which is two corresponding to the two limiting members 8. The guide portion 71 is formed by the two ends of the bottom of the gate plate 7 protruding downwards. The guide portion 71 is an inverted cone shape with a small bottom and a large top. In use, the two guide portions 71 are respectively inserted into the connecting portion. The connecting portion guides the gate plate 7 to run stably downwards. The existence of the connecting portion also provides a cavity for the guide portion 71 of the gate plate 7 to run when concrete is poured inside the corbel formwork, which improves the reliability of the gate plate 7 operation and ensures the sealing reliability of the feed hole.

[0047] In this embodiment, the side formwork 3 with the grouting box 4 includes at least two pieces, which are arranged opposite each other and each has a corresponding grouting box 4. One piece is used for grouting equipment to pour concrete into the corbel formwork, and the other piece is used for vibrating equipment to vibrate the concrete poured into the corbel formwork. This perfectly adapts to the concrete construction needs of areas with dense reinforcement. Specifically, the grouting equipment extends into the grouting box 4 through a grouting pipe to grout the corbel formwork, and the vibrating rod of the vibrating equipment is inserted into the corbel formwork on the opposite side for vibration. This ensures sufficient vibration and avoids quality defects such as honeycomb and pitting, thus comprehensively improving the construction quality of the corbel concrete.

[0048] S2. Open the gate 7 to connect the corbel template of the dense steel reinforcement corbel with at least two pouring boxes 4; and set the pouring end of the pouring equipment and the vibration end of the vibration equipment in their respective preset positions, wherein the pouring end is the pouring pipe and the vibration end is the vibration rod, and the two are set in their respective preset positions.

[0049] S3. Pour concrete into the main building structure 001 with densely reinforced corbels. Stop grouting after the concrete rises to the vicinity of the densely reinforced corbels within the main building formwork. This ensures that the densely reinforced corbels are no longer poured at a high position, but at a relatively low position. Assist with vibration equipment. The freely adjustable pouring and vibration ports ensure that the concrete is fully filled and compacted, completely solving the vibration problem in areas with dense reinforcement and significantly improving the concrete forming quality of the corbels.

[0050] S4. Pour concrete into the densely reinforced corbel; during the pouring process, the vibrating equipment vibrates the concrete poured into the corbel formwork; it should be understood that in step S4, a double-pipe pouring structure can be designed in conjunction with a double-sided vibration method. The double-pipe pouring structure includes both the pouring pipes for the main building and the pouring pipes for the densely reinforced corbel, thereby improving the pouring efficiency; or, pour concrete only into the densely reinforced corbel, where the poured concrete is vibrated and compacted, and at the same time flows towards the main building side, filling the entire formwork.

[0051] S5. When the poured concrete inside the main building is at or above the height of the densely reinforced corbel, the concrete pouring inside the corbel formwork is completed.

[0052] In this embodiment, the top of the grouting box 4 is open and not lower than the height of the densely reinforced steel corbel; the grouting box 4 has a guide surface that is inclined towards the discharge port 6 to facilitate grouting into the corbel template, which can reduce manual input, improve construction efficiency, and save construction costs.

[0053] S6. Remove the pouring end of the pouring equipment and the vibrating end of the vibrating equipment from their respective preset positions, and close the gate 7 to close the corbel formwork of the densely reinforced corbel.

[0054] S7. After recovering the excess concrete in the pouring tank 4, dismantle the pouring tank 4. The device is detachable, reusable, energy-saving and environmentally friendly.

[0055] In this embodiment, the pouring tank 4 is equipped with a controllable discharge port 9, which is located at the bottom of the pouring tank 4. An outer side plate 10, sloping downwards towards the corbel template, is provided on the outside of the pouring tank. The outer side plate 10 is controlled to open or close the outer opening of the pouring tank. The function of the discharge port 9 is to equip the pouring tank 4 with a surplus material recycling system, which can effectively recycle excess concrete, significantly reducing material waste and construction costs.

[0056] In this embodiment, the inner end, outer end, and top of the pouring box are all open. Specifically, the pouring box 4 includes an assembly plate for detachable fixing on the side template 3. The top of the assembly plate has a rectangular discharge port 6. Along the direction of the corbel's extension in the main building, both sides of the discharge port 6 are provided with right-angled triangular side plates. The hypotenuse of the right-angled triangles slopes from top to bottom toward the corbel template. The openings where the hypotenuses of the two side plates are located are the unloading ports 9. Guide rails are provided at the corresponding positions of the hypotenuses of the two side plates. The pouring box 4 also includes an outer side plate 10 that is driven to control the opening and closing of the unloading port 9. When in use, the outer side plate 10 is guided by the guide rail and sealed to open or close the unloading port 9. The guide surface is the side of the outer side plate 10 facing the corbel template. The outer side plate 10 is provided with a side plate handle.

[0057] This solution has the following advantages compared to existing technologies:

[0058] (1) Economical and efficient construction: The side pouring and vibration process can be used directly with conventional vibration equipment and standard concrete mix proportions. Compared with the traditional small-diameter vibrator and small-particle aggregate scheme, the material and equipment costs are significantly reduced, while the construction efficiency is improved.

[0059] (2) Flexible formwork system: The innovative precast grouting box design can be seamlessly spliced ​​with conventional formwork on site, making full use of existing wooden formwork resources and greatly improving construction adaptability and turnover material utilization rate.

[0060] (3) Quality assurance design: The freely set pouring and vibration port ensures that the concrete is fully filled and compacted, completely solving the problem of vibration in areas with dense reinforcement, and significantly improving the forming quality of corbel concrete.

[0061] (4) Resource recycling: Equipped with an intelligent waste material recycling system, it can efficiently collect and utilize excess concrete, resulting in significant savings in overall construction costs.

[0062] It provides a more efficient and environmentally friendly solution for the concrete construction of corbels in areas with dense reinforcement.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
