Description

Technical Field

[0001] The invention relates to the technical field of prefabricated assembled concrete structures, and in particular to a novel prefabricated concrete frame column and an installation method thereof. Background Art

[0002] With the advancement of the construction industrialization process, prefabricated construction technology has gradually emerged and has been widely used. Prefabricated buildings are produced in a standardized manner in factories and transported to the construction site for assembly, which greatly improves construction efficiency and quality controllability.

[0003] After searching, the Chinese patent number CN212271212U discloses that the utility model discloses a precast concrete frame column, which belongs to the technical field of precast assembled concrete structures. The frame column includes an upper frame column and a lower frame column of the same structure, and a beam and a floor slab are arranged at the top of the lower frame column. The upper frame column is provided with embedded longitudinal steel bars inside, and at least one supporting leg is embedded at the bottom of the upper frame column, and a gasket is arranged between the supporting leg and the lower frame column. The longitudinal steel bars of the upper frame column and the longitudinal steel bars of the lower frame column are connected by an extrusion sleeve, and a post-cast section is reserved between the upper frame column and the lower frame column, and dense steel bars are arranged inside the post-cast section. The utility model adopts the precast concrete frame column of the above structure, which can solve the problems of laborious installation, high cost and difficult detection of the existing precast concrete frame column structure.

[0004] However, in the existing prefabricated and assembled concrete structure, when concrete is injected into the frame columns, it is necessary to effectively support the frame columns to ensure their stability and safety during the pouring process. The above-mentioned support method adopts a simple fixed bracket or a temporary support structure. These support methods are not only cumbersome and time-consuming to install, but also difficult to flexibly adjust according to the actual height of the frame columns, thereby affecting the construction efficiency and support effect. Especially in the construction of high-rise buildings or special structures, the height and shape of the frame columns often vary, and the requirements for the support structure are also more stringent. Traditional fixed brackets or temporary support structures are often difficult to meet these diverse needs, which can easily lead to safety problems such as tilting, deformation and even collapse of the frame columns during the pouring process.

In addition, by accurately adjusting the shrinkage component, it can be ensured that the height of the support point matches the actual requirements of the frame column as a whole 1, thereby improving the safety of the overall structure.

Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0035] Embodiment 1; See also Figure 1-Figure 8 In an embodiment of the present invention, a novel precast concrete frame column includes: a frame column as a whole 1, a longitudinal steel bar 2 is installed inside the frame column as a whole 1, and a dense steel bar 3 is installed on the outer ring of the longitudinal steel bar 2; a supporting mechanism, the supporting mechanism is located outside the frame column as a whole 1 and supports the frame column as a whole 1, the supporting mechanism includes a connecting component, a fixing component and a shrinking component, the connecting component is located outside the frame column as a whole 1 and supports the frame column as a whole 1, the fixing component is located outside the frame column as a whole 1 and is used to connect the connecting component to the frame column as a whole 1, the shrinking component is located inside the connecting component and can adjust the length of the connecting component and support the frame column as a whole 1 at different heights; a shaking mechanism, the shaking mechanism is located at the top of the frame column as a whole 1 and shakes the concrete inside the frame column as a whole 1 and reduces bubbles inside the concrete.

[0036] The connection assembly includes a support plate 4 installed on the outside of the frame column 1 as a whole, an adjustment rod 5 is hinged on one side of the support plate 4, a fixing rod 6 is installed on the outer ring of the adjustment rod 5, a fixing plate 7 is installed on the bottom of the fixing rod 6, the support plate 4 is provided with four groups and distributed in a circumferential array, and the adjustment rod 5 and the fixing rod 6 are both provided with four groups and distributed in a circumferential array. The fixing assembly includes a connecting strip plate 8 installed on the outside of the frame column 1 as a whole, the inner cavities of the connecting strip plate 8 and the support plate 4 are both provided with connecting screw holes 9, the inner cavities of the connecting screw holes 9 are threadedly connected with connecting screws 10, the outer rings of the connecting screws 10 are installed with connecting nuts 11, the connecting screw holes 9 are provided with multiple groups and are linearly distributed, the inner cavity of the fixing plate 7 is provided with fixing screw holes 12, and the inner cavities of the fixing screw holes 12 are threadedly connected with fixing screws 13.

There are multiple groups of contraction screw holes 14 and they are horizontally distributed.

[0037] The working principle of the embodiment of the present invention is as follows: first, the support plate 4 is installed to the outside of the frame column 1 through the connection assembly, and the support plate 4 is distributed in a circumferential array to ensure uniform support of the frame column 1. The connection screw holes 9 on the connecting strip 8 and the corresponding connection screw holes 9 in the inner cavity of the support plate 4 are connected by using the connection screw rod 10 and the connection nut 11 for fastening connection. This design is not only convenient for installation and adjustment, but also enhances the stability of the connection.

[0038] Next, according to the height requirement of the frame column 1, the shrinkage assembly is used for precise adjustment. The shrinkage screw hole 14 is opened inside the adjustment rod 5 and the fixed rod 6. By rotating the shrinkage screw 15 and tightening the shrinkage nut 16, the effective length of the adjustment rod 5 relative to the fixed rod 6 can be changed, thereby adjusting the height of the support point. At the same time, the horizontal distribution design of multiple groups of shrinkage screw holes 14 enables reliable support at different height positions.

[0039] After adjusting to the required height, the fixing plate 7 matches the threaded hole on the preset fixing point on the outer side of the frame column 1 through the fixing screw hole 12 in the inner cavity of the fixing plate 7, and is locked using the fixing screw 13. This process ensures the stability of the support mechanism during the pouring process and prevents the support from loosening due to the pressure of concrete pouring.

[0040] Embodiment 2; See also Figure 1-Figure 8In the embodiment of the present invention, the shaking mechanism includes a vibrating rod 17 installed between the longitudinal steel bars 2, a connecting plate 18 is installed on the top of the vibrating rod 17, a working plate 19 is installed on the top of the connecting plate 18, working screw holes 20 are provided in the inner cavities of the working plate 19 and the connecting plate 18, a working screw 21 is threadedly connected in the inner cavity of the working screw hole 20, and a support column 22 is installed at the bottom of the working plate 19.

The connecting plate 18 and the working plate 19 are made of Q235B steel plates to provide sufficient strength and stability.

[0041] The bottom of the frame column 1 is installed with a mounting plate 23, and the inner cavity of the mounting plate 23 is provided with a mounting screw hole 24, and the inner cavity of the mounting screw hole 24 is threadedly connected with a mounting screw rod 25, and the mounting screw hole 24 and the mounting screw rod 25 are provided with four groups and distributed in a rectangular array. The frame column 1 is made of high-strength, low-shrinkage C60 precast concrete, and its compressive strength is not less than 60MPa to meet the bearing capacity requirements of high-rise buildings and special structures. The longitudinal steel bars 2 are made of HRB400 grade hot-rolled ribbed steel bars to ensure the longitudinal bearing capacity of the frame column, and the dense steel bars 3 are made of HRB400 grade hot-rolled ribbed steel bars, which are tightly wound around the outer ring of the longitudinal steel bars 2 in a spiral shape to improve the shear resistance and seismic resistance of the frame column.

[0042] The working principle of the embodiment of the present invention is: after the concrete pouring is completed, the shaking mechanism begins to play its key role. The vibrating rod 17, as the core component of the shaking mechanism, is designed as a high-frequency vibrator with a vibration frequency of 50Hz and a power of 1.5kW. This design ensures that the vibrating rod 17 can generate sufficient vibration energy, effectively penetrate the concrete layer, and promote the rapid removal of bubbles inside the concrete, thereby improving the density and uniformity of the concrete. The vibrating rod 17 is tightly connected to the working plate 19 through the connecting plate 18. Both parts are made of Q235B steel plate. This material not only has excellent strength and toughness, but also can effectively resist the vibration stress generated during the vibration process, ensuring the stability and durability of the shaking mechanism.

[0043] After pouring is completed, the shaking mechanism is started, and the high-frequency vibration of the vibrating rod 17 is transmitted to the interior of the concrete through the connecting plate 18 and the working plate 19, thereby effectively removing bubbles; the rectangular array distribution design of the mounting screw holes 24 and the mounting screws 25 on the mounting plate 23 not only provides a stable support point, but also facilitates on-site installation and adjustment. By rotating the mounting screws 25, the horizontal and vertical positions of the frame column as a whole 1 can be accurately controlled to ensure its close connection with the foundation structure and overall stability.

[0044] Embodiment 3; See also Figure 1-Figure 8 In an embodiment of the present invention, a novel method for installing precast concrete frame columns is provided, and the method comprises the following steps: Step S1, precasting the frame column as a whole 1, ensuring that its size, strength and steel bar arrangement meet the design requirements, determining the installation position of the frame column according to the design drawings at the construction site, and pre-burying the foundation embedded parts; Step S2, assembling the support mechanism, adjusting the shrinkage assembly according to the height of the frame column, ensuring that the support plate 4 is tightly fitted with the outer side of the frame column as a whole 1, and firmly connecting the support mechanism with the frame column as a whole 1 by using the fixing assembly to ensure the stability of the support; Step S3, using the lifting equipment to hoist the frame column as a whole 1 to a predetermined position, slowly lowering it to the foundation embedded parts, adjusting the verticality and horizontality of the frame column, and after meeting the design requirements, firmly connecting the frame column with the foundation structure by using the mounting plate 23 and the mounting screw 25; Step S4, starting the vibrating rod 17 in the shaking mechanism, vibrating and compacting the concrete inside the frame column until the bubbles inside the concrete are basically eliminated, and after the concrete reaches the design strength, removing the support mechanism to complete the installation of the frame column.

[0045] Step S2 also includes the following steps: Step S2.1, support mechanism assembly: assemble the support plate 4, adjustment rod 5, fixing rod 6 and fixing plate 7 and other components according to the design drawings to ensure that the connection between the components is firm and reliable; Step S2.2, height adjustment: according to the actual height of the frame column as a whole 1, adjust the shrinkage screw 15 and the shrinkage nut 16 in the shrinkage assembly to make the support plate 4 fit tightly with the outer side of the frame column as a whole 1. During the adjustment process, the stability and balance of the support mechanism should be ensured; Step S2.3, fixed connection: use the connecting screw 10 and the connecting nut 11 in the fixing assembly to firmly connect the support mechanism to the frame column as a whole 1. During the connection process, the matching accuracy of the connecting screw hole 9 and the connecting screw 10 should be ensured to avoid loosening or misalignment.

[0046] Step S3 also includes the following steps: Step S3.1, hoisting preparation: select appropriate lifting equipment to ensure that the lifting capacity meets the weight requirement of the frame column 1 as a whole, and prepare the wire rope, lifting equipment and safety protection measures for hoisting; Step S3.2, hoisting operation: connect the hook of the lifting equipment to the hoisting point on the top of the frame column 1 as a whole, and slowly lift the frame column 1 as a whole to a predetermined height. During the hoisting process, the stability and safety of the lifting equipment should be ensured to avoid tilting or collision of the frame column 1 as a whole; Step S3.3, position adjustment: Slowly lower the frame column as a whole 1 onto the foundation embedded parts, and use the level and plumb meter to adjust the verticality and horizontality of the frame column as a whole 1. During the adjustment process, ensure that the frame column as a whole 1 fits tightly with the foundation embedded parts to avoid gaps or misalignment; Step S3.4, fixed connection: Use the mounting plate 23 and the mounting screw 25 to firmly connect the frame column as a whole 1 to the foundation structure. During the connection process, ensure the matching accuracy of the mounting screw hole 24 and the mounting screw 25 to avoid looseness or misalignment. At the same time, check the tightness and stability of the connection parts.

[0047] The working principle of the embodiment of the present invention is: in the prefabrication stage, the frame column as a whole 1 is produced strictly according to the design drawings to ensure that its size, strength and steel bar arrangement meet the engineering requirements. At the construction site, the installation position of the frame column is accurately located according to the design drawings, and the foundation embedded parts are pre-buried. The embedding of the foundation embedded parts must ensure accurate position and firm fixation, laying the foundation for the subsequent accurate installation of the frame column. The support mechanism is composed of components such as a support plate 4, an adjustment rod 5, a fixing rod 6 and a fixing plate 7. During assembly, the connection between the components must be ensured to be firm and reliable, and high-strength bolts or welding are used to ensure the overall stability of the support mechanism. In the height adjustment stage, the support plate 4 is closely fitted to the outer side of the frame column as a whole 1 by accurately rotating the contraction screw 15 and the contraction nut 16. In this process, the stability and balance of the support mechanism need to be monitored in real time to avoid tilting or shaking. When fixedly connected, the connecting screw 10 and the connecting nut 11 are used to ensure the firm connection between the support mechanism and the frame column as a whole 1. The connection screw hole 9 and the connection screw rod 10 must be matched with high precision to avoid looseness or misalignment, thereby ensuring the stability of the support mechanism during hoisting and vibration compaction.

[0048] Before lifting, it is necessary to select appropriate lifting equipment to ensure that its lifting capacity meets the weight requirements of the frame column as a whole 1. At the same time, prepare the wire rope, lifting equipment and safety protection measures for lifting to ensure the safety and stability of the lifting process. During the lifting operation, the hook of the lifting equipment is firmly connected to the lifting point at the top of the frame column as a whole 1, and the frame column is slowly lifted to the predetermined height. During the lifting process, it is necessary to monitor the stability and safety of the lifting equipment in real time to avoid tilting or collision of the frame column. After the frame column is lowered onto the foundation embedded parts, use the level and plumb meter to make precise adjustments to ensure that the verticality and horizontality of the frame column meet the design requirements. During the adjustment process, it is necessary to ensure that the frame column fits tightly with the foundation embedded parts to avoid gaps or misalignment, thereby ensuring the overall stability and bearing capacity of the frame column.

[0049] After the overall positioning of the frame column 1 is completed, the vibrating rod 17 in the shaking mechanism is started to vibrate and compact the concrete inside the frame column. The high-frequency vibration energy of the vibrating rod 17 penetrates the concrete layer, effectively removes the bubbles inside the concrete, and improves the density and uniformity of the concrete. During the vibration compaction process, the state of the concrete needs to be monitored in real time to ensure that the bubbles are basically eliminated. After the concrete reaches the designed strength, the support mechanism is removed.
