Description

Technical Field

[0001] The invention relates to the technical field of building structure reconstruction, and in particular to a column-drawing reinforcement structure suitable for a multi-story frame of an I-beam structure and a construction method. Background Art

[0002] In construction projects, cutting and reinforcement combined with column extraction technology is an important construction method, which aims to expand the space by removing some columns while ensuring the stability and safety of the structure. The following are several popular cutting and reinforcement combined with column extraction technologies and their corresponding characteristics.

[0003] Joist beam removal and column reinforcement technology; Technical features: New joists are added to replace the removed columns to transfer the load to the joists. Applicable to factories and buildings with steel or reinforced concrete structures.

[0004] Disadvantages: The construction period may be longer because the design, installation and commissioning of the joists are required. Although the removal of the columns can free up the bottom space, the installation of the joists squeezes the space above the building.

[0005] Static blasting column extraction technology; Technical features: Static blasting technology is a technology that uses expansion agents (such as silent crushing agents) to produce chemical reactions under specific conditions to form expansion pressure, causing cracks in objects such as rocks or concrete and gradually breaking them. During the column extraction process, holes are drilled around the column and expansion agents are injected to gradually break and separate the column.

[0006] Disadvantages: Although static blasting technology has less vibration than traditional blasting technology, it may still have some impact on surrounding structures, especially when the column is located in a sensitive area. The entire construction process is relatively long because it requires drilling, injecting expansion agent and waiting for its reaction. The equipment and material costs required for static blasting technology are relatively high, and the construction difficulty and technical requirements are also high.

[0007] Hydraulic jacking column extraction technology; Technical introduction: Hydraulic jacking technology is a technology that uses hydraulic jacks and other equipment to lift the column to a certain height, and then cut or remove it below. During the column extraction process, it is usually necessary to set up a temporary support structure around the column to ensure the stability of the structure during the jacking process.

[0008] Disadvantages: Hydraulic jacking technology requires accurate calculation of the jacking force and the stability of the supporting structure, and a temporary supporting structure is set up, which occupies a large indoor space. There are great safety risks during the jacking and cutting process, and strict protective measures need to be taken.

[0009] In summary, various cutting and reinforcement combined with column extraction technologies have their unique advantages and disadvantages; however, when extracting columns in multi-story factories, the existing technical solutions can only be used for extracting columns on the top floor; therefore, there is an urgent need for a column extraction reinforcement structure and construction method suitable for multi-story frames with I-beam structures, which can be used to extract columns on any floor without dismantling the roof structure, effectively avoiding the occupation of indoor space and effectively maintaining structural stability during the column extraction process, and can also improve the bearing capacity and seismic performance of the overall structure after the column extraction is completed.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Embodiment 1

[0039] Reference Figure 1-Figure 5 The present invention provides a column removal reinforcement structure suitable for a multi-story frame of an I-beam structure, including a middle member 1 placed on the top surface of a column 4 to be removed, the middle member 1 is fixedly connected with a horizontal member 3, the horizontal member 3 is arranged on the top surface of an original crossbeam 6, and vertical members 2 for supporting the horizontal member 3 are respectively arranged at both ends of the horizontal member 3, and the two vertical members 2 are respectively arranged on the outside of the two outermost original columns 5.

[0040] The present invention supports the transverse member 3 by means of a vertical member 2 arranged on the outside of the original column 5, installs the transverse member 3 on the original crossbeam 6, and connects the two transverse members 3 through an intermediate member 1, so as to carry out column extraction construction on the columns 4 to be extracted on any floor of a multi-story factory building; the present invention not only effectively avoids the occupation of indoor space, so as to effectively maintain the stability of the overall structure during the column extraction process, but also can improve the bearing capacity and seismic resistance of the overall structure after the column extraction is completed.

[0041] In a further optimized solution, the middle member 1 includes a lower steel plate 12 fixedly connected to the top surface of the column 4 to be extracted, an upper steel plate 11 is arranged above the end of the lower steel plate 12 away from the column 4 to be extracted, and a plurality of threaded steel bars 13 are arranged between the upper steel plate 11 and the lower steel plate 12. The spacing between the upper steel plate 11 and the lower steel plate 12 can be adjusted by the plurality of threaded steel bars 13, so that the transverse member 3 can be effectively located between the upper steel plate 11 and the lower steel plate 12.

[0042] Further optimizing the scheme, a plurality of threaded steel bars 13 are arranged around the column 4 to be extracted. The plurality of threaded steel bars 13 are arranged around the reserved section of the column 4 to be extracted.

[0043] Threaded steel bar 13, also known as hot-rolled ribbed steel bar, is a steel bar with longitudinal ribs and transverse ribs on the surface, usually used for the skeleton of reinforced concrete building components. The main purpose of threaded steel bar 13 is to withstand tensile stress in concrete structures. Its transverse ribs can enhance the bonding performance between steel bars and concrete, better transfer stress, and enable steel bars and concrete to work better in coordination and withstand external forces together. Threaded steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.

[0044] In order to ensure that the lower steel plate 12 can be stably located on the top surface of the column 4 to be extracted, the cross-sectional area of ​​the lower steel plate 12 is larger than the cross-sectional area of ​​the column 4 to be extracted.

[0045] According to a further optimization scheme, a plurality of through holes are respectively provided on the upper steel plate 11 and the lower steel plate 12, and the through holes on the upper steel plate 11 correspond to the through holes on the lower steel plate 12, so that the threaded steel bar 13 can pass through the two corresponding through holes.

[0046] According to a further optimized solution, two ends of the threaded steel bar 13 respectively pass through the through holes on the upper steel plate 11 and the through holes on the lower steel plate 12 and are fixedly connected to the through holes.

[0047] The spacing between the upper steel plate 11 and the lower steel plate 12 can be adjusted by a plurality of threaded steel bars 13 , so that the transverse member 3 can be effectively located between the upper steel plate 11 and the lower steel plate 12 .

[0048] According to a further optimized solution, the vertical member 2 includes a first I-beam 21 , and the first I-beam 21 is arranged on the outside of the original column 5 .

[0049] According to a further optimized solution, the transverse member 3 includes a second I-beam 31 , and the second I-beam 31 is connected to the original crossbeam 6 through a plurality of rivets.

[0050] I-beam is a long steel bar with an I-shaped cross section, also known as a steel beam. I-beams are mainly divided into ordinary I-beams, light I-beams and wide flange I-beams (also known as H-beams). Ordinary I-beams and light I-beams have formed national standards, with specifications of 10-60, that is, the corresponding height is 10cm-60cm. The cross-section of the wide flange I-beam is characterized by two parallel legs and no slope on the inner side of the legs.

[0051] Characteristics of I-beam:

[0052] Cross-sectional shape: The cross-sectional shape of the I-beam is an I-shaped steel structure, with flanges on the upper and lower sides and a web in the middle. This design allows the I-beam to better withstand pressure and shear forces when subjected to stress, and has a higher bending, torsion and shear resistance.

[0053] Material and performance: I-beams are made of steel, which has the high strength, high load-bearing capacity, and tensile and compressive resistance of steel itself. At the same time, the material of I-beams is uniform, the cutting precision is high, and it has high reliability and stability.

[0054] Pass design: The specifications of I-beams are expressed in centimeters of waist width, such as No. 10 I-beam, whose waist width is 10cm. Pass systems include straight rolling pass system, oblique rolling pass system and mixed pass system, as well as special rolling methods to meet different production needs.

[0055] Advantages of I-beam:

[0056] High strength: The cross-sectional shape and material of the I-beam make it highly resistant to bending, torsion and shearing, and can withstand greater pressure and shear force.

[0057] Good stability: The I-beam has uniform material, high cutting accuracy, high reliability and stability, and is not prone to deformation or breakage.

[0058] Easy construction: I-beams have a light weight and are easy to process and install on site, which greatly shortens the construction period and improves construction efficiency.

[0059] Material saving: The cross-section of I-beam is small, which can achieve a higher material saving effect from the perspective of optimizing structure and increasing load. Compared with ordinary structures, I-beam structures can reduce weight by 15%-20%.

[0060] Widely used: I-beams are widely used in the fields of construction, bridges, machinery manufacturing, etc., as materials for building structure supports, beams, columns, trusses, roofs, etc., as well as bridge supports, suspensions, beams and foundations, etc. In addition, I-beams can also be processed into T-shaped steel, honeycomb beams, etc. to meet various engineering design and production needs.

[0061] According to a further optimized solution, steel cages are respectively provided on the first I-beam 21 and the original column 5 as well as on the second I-beam 31 and the original crossbeam 6 .

[0062] Steel cage is a commonly used structure in construction projects, mainly used in concrete components to play a tensile role. It is usually composed of main bars, stirrups, frame bars, reinforcing bars, protective layer pads and other components.

[0063] The steel cages on the first I-beam 21 and the second I-beam 31 facilitate the pouring of concrete.

[0064] In a further optimized solution, the second I-beam 31 is disposed between the two first I-beams 21 , and both ends of the second I-beam 31 are respectively welded to the end of the first I-beam 21 that is higher than the original column 5 , so that the first I-beam 21 can be effectively connected to the second I-beam 31 .

[0065] A construction method for a column-removing reinforcement structure applicable to a multi-story frame of an I-beam structure comprises the following steps:

[0066] S1. Laterally reinforce the foundations of the original columns 5 on both sides of the planned columns 4 to be removed, and prepare for the connection of the original crossbeams 6. After the reinforcement is completed, first install the middle member 1 on the top surface of the column 4 to be removed; first weld the lower steel plate 12 to the top surface of the column 4 to be removed, and then determine the distance between the upper steel plate 11 and the lower steel plate 12 according to the specifications of the horizontal member 3, and then pass the threaded steel bars 13 through the through holes on the upper steel plate 11 and the through holes on the lower steel plate 12 corresponding to the through holes, and then weld the threaded steel bars 13 in the through holes to provide reliable support points for the installation of the horizontal member 3.

[0067] By arranging the threaded steel bars 13 on the cross-section of the upper steel plate 11 and the lower steel plate 12 where the cross-section is larger than the cross-section of the column 4 to be extracted, a reliable support point is provided for the subsequent installation of the second I-beam 31; this not only ensures the firmness of the connection, but also improves the overall bearing capacity of the structure; at the same time, it can also effectively reduce the arrangement of indoor supporting structures.

[0068] S2. Then, vertical members 2 are respectively arranged on the outer sides of the original columns 5 on both sides of the column 4 to be extracted; the first I-beam 21 is arranged on the outer side of the original column 5, and the outer wall of one side wing plate of the first I-beam 21 is made to face the original column 5, so that the first I-beam 21 and the original column 5 bear the load together; then, a steel cage is installed on the first I-beam 21, and one side of the steel cage on the first I-beam 21 is welded to the original column 5.

[0069] S3. Install the transverse member 3 on the original crossbeam 6, and install the transverse member 3 into the middle member 1, and install both ends of the transverse member 3 on the vertical member 2; point the wing plate on one side of the second I-beam 31 toward the original crossbeam 6, connect the wing plate of the second I-beam 31 to the original crossbeam 6 through a plurality of rivets, and allow the second I-beam 31 to extend between the upper steel plate 11 and the lower steel plate 12; weld one end of the steel cage on the second I-beam 31 to the threaded steel bar 13, so that the steel cage on the second I-beam 31 can be effectively located between the upper steel plate 11 and the lower steel plate 12; weld the other end of the steel cage on the second I-beam 31 to one end of the steel cage on the first I-beam 21, so that the steel cage on the first I-beam 21 can be effectively connected to the steel cage on the second I-beam 31.

[0070] By connecting the wing plate of the second I-beam 31 to the original crossbeam 6 through a plurality of rivets, the firmness of the connection is ensured and the overall bearing capacity of the structure is improved; at the same time, the use of the second I-beam 31 makes the construction convenient and economical, and reduces the construction cost.

[0071] S4. Set up formwork for the middle member 1, the vertical member 2, and the horizontal member 3; that is, set up formwork at all the steel cages so that all the steel cages are inside the formwork.

[0072] S5. Pour concrete into the formwork; through the concrete, the steel cage can form reinforced concrete with the first I-beam 21 and the second I-beam 31, thereby enhancing its bearing capacity and strengthening the anchoring capacity of the upper steel plate 11 and the lower steel plate 12.

[0073] The combination of concrete pouring and welding ensures the firmness of the connection and facilitates construction and subsequent maintenance.

[0074] S6. After the concrete reaches the required strength, the demolition section of column 4 to be removed is demolished.

[0075] The cutting section of the column 4 to be extracted is cut, and the cut column is safely transported out of the building using a lifting device.

[0076] The present invention adopts non-destructive construction: through the first I-beam 21 and the second I-beam 31, column extraction construction is achieved without dismantling the roof system, thereby avoiding damage to the factory building structure caused by the construction.

[0077] Reduce costs: Since there is no need to dismantle and rebuild the roof system, and the construction and dismantling of temporary support structures are reduced, the construction cost of the present invention is significantly reduced; at the same time, the indoor working environment is also conducive to improving construction efficiency, further reducing labor costs.

[0078] Shorten the construction period: The use of hoisting to remove the columns and install the first I-beam 21 and the second I-beam 31 structure greatly improves the construction speed. In addition, the indoor working environment is stable and not affected by the weather, which is conducive to the continuity and stability of the construction progress, thereby shortening the overall construction period.

[0079] Improve structural stability: By reinforcing and transforming the column foundation and pouring concrete on the first I-beam 21 and the second I-beam 31, the construction method of the present invention not only ensures the structural stability during the column extraction process, but also improves the bearing capacity and seismic performance of the overall structure.

[0080] The column-removing reinforcement structure and construction method of the present invention applicable to a steel-framed concrete structure are applicable to the following scenarios:

[0081] Single-storey industrial plant: It is particularly suitable for single-storey industrial plants that need to adjust the spatial layout or optimize the production process. Through the construction of column extraction, the internal space of the plant can be flexibly adjusted to meet different production needs.

[0082] Renovation of old factory buildings: For old factory buildings that need structural reinforcement and renovation, this invention provides an economical and efficient solution. Through reinforcement and renovation and the design of new structures, the bearing capacity and earthquake resistance of the factory buildings can be improved, and the service life can be extended.

[0083] Special environmental requirements: In scenarios where it is necessary to maintain a stable indoor environment and avoid external interference, such as precision manufacturing, electronic production and other industries, the construction method of the present invention has significant advantages. Through indoor operations, the stability of construction quality and progress can be ensured to meet special environmental requirements.

[0084] Other occasions where column extraction is required: In addition to single-story industrial plants and renovation of old plants, the present invention can also be applied to other occasions where column extraction is required, such as commercial buildings, storage facilities, etc. Through flexible construction design and optimized construction process, the column extraction requirements in different occasions can be met.

[0085] Reference Figure 5 The present invention can also perform column extraction operations on any floor of a multi-story building, that is, perform separate column extraction construction on the first floor, the second floor, and the third floor of a three-story factory building.

[0086] Embodiment 2

[0087] When a large-span space needs to be formed and multiple columns need to be extracted, the columns to be extracted are planned so that they are located on a straight line between the two outermost original columns 5. Then, the construction of multiple columns to be extracted can be completed by performing a construction method for a column extraction reinforcement structure suitable for a multi-story frame of an I-beam structure according to the present invention.

[0088] Embodiment 3

[0089] When performing the column extraction operation at the bottom layer, the threaded steel bar 13 penetrates the original floor slab 7 on the bottom layer. By penetrating the original floor slab 7 on the bottom layer, the column extraction operation can be effectively performed on the bottom layer of the multi-story factory building. By performing the construction method of the column extraction reinforcement structure applicable to the multi-story frame of the I-beam structure according to the present invention, the construction of the column to be extracted can be completed.
