Description

Technical Field

[0001] The utility model relates to the field of building renovation, and more specifically, to a support column structure for the renovation of brick-concrete buildings. Background Technique

[0002] In the renovation projects of existing brick-concrete buildings, changes in building layouts often occur. In order to obtain a larger space, load-bearing walls are often removed, and only brick columns (which can also be called local small walls) supporting the upper concrete beams are retained. In terms of the force transmission path, this renovation is feasible, and there are corresponding reinforcement methods in codes and atlases. It only needs to reinforce the brick columns with concrete jackets and locally reinforce the strip foundation at the bottom of the brick wall at the position of the brick columns to achieve the goal. However, after on-site investigation, things often go against expectations. Some old buildings did not have foundations due to tight funds during construction, and the brick walls were directly located on the foundation soil, lacking effective bearing capacity at the bottom. If only the brick columns are reinforced with concrete jackets around them, it is obviously difficult to meet the force requirements, and the stability of the independent columns is also worrying, seriously endangering the safety of the building. Although pouring a new concrete independent foundation can solve the problems of foundation force and column stability, it also faces the problem of how to reliably connect the column and the foundation. Obviously, using conventional methods for reinforcement does not have a quick and reliable solution to such problems. Content of the Utility Model

[0021] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0022] An embodiment of the utility model provides a support column structure for the transformation of brick-concrete buildings, which includes a brick column 10, a base 20, hoop steel bars 30, foundation concrete 40, and hoop concrete 50; a central opening is formed in the base 20 to form a hoop structure, and the base 20 is sleeved on the bottom of the brick column 10 through the hoop structure and fixedly connected to the foundation soil 60; the hoop steel bars 30 are sleeved on the brick column 10, the bottom end of the hoop steel bars 30 is welded to the hoop structure, and the upper end of the hoop steel bars 30 extends to the top of the brick column 10; the foundation concrete 40 is poured into the gap between the hoop structure and the brick column 10 to reinforce and connect the base 20 and the bottom of the brick column 10; the hoop concrete 50 is poured between the brick column 10 and the hoop steel bars 30. Thus, there is no need to re-pour the concrete independent foundation, and the bottom end of the brick column 10 is reinforced through the hoop structure of the base 20 and the foundation concrete 40 and stably connected to the foundation soil 60; the upper column body of the brick column 10 is integrally reinforced through the hoop steel bars 30 and the hoop concrete 50, ensuring that the brick column 10 can provide a stable supporting effect for the upper concrete beam after the load-bearing wall of the brick-concrete building is transformed into the brick column 10. It solves the problem that when the brick column 10 in the transformation project of the existing brick-concrete building is reinforced and transformed into an independent column, it lacks a foundation, resulting in the difficulty for the independent column to meet the stress requirements and the inability to ensure stability.

[0023] Specifically, the base 20 includes a bottom plate 21 and a hoop steel plate 22. The bottom plate 21 is a square steel plate, and a square hole is opened in the center of the bottom plate 21. The side length of the square hole is slightly larger than the side length of the brick column 10. The bottom plate 21 is sleeved on the bottom end of the brick column 10 through the square hole and fixedly connected to the foundation soil 60. In actual operation, since the upper and lower ends of the brick column 10 are respectively connected to the foundation soil 60 and the upper concrete beam, the square hole of the complete bottom plate 21 cannot be installed; optionally, the bottom plate 21 is welded by two mutually symmetric rectangular plates, and mutually symmetric rectangular grooves are opened on the opposite sides of the two rectangular plates. The two rectangular grooves together form a square hole. After the rectangular grooves of the two rectangular plates can be inserted into the brick column 10 from both sides of the brick column 10, the two rectangular plates are welded to close the square hole, finally facilitating the installation of the bottom plate 21.

[0024] The hoop steel plate 22 is a rectangular steel plate. There are four hoop steel plates 22. The bottom length of each hoop steel plate 22 is equal to the side length of the square hole, and the height of each hoop steel plate 22 is selected according to the situation; the bottom sides of the four hoop steel plates 22 are welded corresponding to the four sides of the square hole, and the side edges of the four hoop steel plates 22 are welded to each other to enclose a hoop structure. The side length of the hoop structure is slightly larger than the side length of the brick column 10, so that the foundation concrete 40 can be poured into the gap between the hoop structure and the brick column 10 to reinforce and connect the base 20 and the bottom of the brick column 10.

[0025] Further, the base 20 further includes stiffening plates 23. There are multiple stiffening plates 23, and the multiple stiffening plates 23 are evenly spaced circumferentially around the bottom plate 21; the bottom edge of each stiffening plate 23 is welded to the upper surface of the bottom plate 21, and the side edge of each stiffening plate 23 is welded to the side wall of the jacket steel plate 22, thereby reinforcing and connecting the bottom plate 21 and the jacket steel plate 22, effectively improving the structural strength of the base 20.

[0026] Further, the jacket reinforcement 30 includes longitudinal bars 31 and stirrups 32. There are multiple longitudinal bars 31, and the multiple longitudinal bars 31 are evenly spaced circumferentially around the jacket structure. The lower end of each longitudinal bar 31 is welded to the inner side wall of the jacket steel plate 22, and the upper end of each longitudinal bar 31 extends vertically to the top of the brick column 10. The upper end of the longitudinal bar 31 is slightly lower than the top of the brick column 10 so that the jacket concrete 50 can completely wrap the upper end of the longitudinal bar 31; there are multiple stirrups 32, and the multiple stirrups 32 are evenly spaced vertically. Each stirrup 32 connects and fastens the multiple longitudinal bars 31. The jacket concrete 50 is poured into the jacket reinforcement 30 to reinforce the outside of the brick column 10.

[0027] The specific construction process of the support column structure for the transformation of brick-concrete buildings in the embodiment of the present invention is as follows:

[0028] Step 1: As Figure 1 shown, confirm the position of the brick column 10 according to the position of the upper load-bearing beam and set out the line. Cut out two operation spaces on both sides of the brick wall 70 where the brick column 10 is to be formed.

[0029] Step 2: As Figure 2 shown, weld the bottom plate 21, the jacket steel plate 22 and the stiffening plates 23 at the bottom of the formed brick column 10 to form the base 20.

[0030] Step 3: As Figure 3 shown, weld the longitudinal bars 31 for reinforcing the brick column 10 inside the jacket steel plate 22.

[0031] Step 4: As Figure 4 shown, pour the foundation concrete 40 into the jacket structure formed by multiple jacket steel plates 22.

[0032] Step 5: As Figure 5 shown, bind the stirrups 32 to the longitudinal bars 31 to connect the longitudinal bars 31 to each other.

[0033] Step 6: As Figure 6 shown, form a mold outside the jacket reinforcement 30 and pour the jacket concrete 50, so that the base 20, the foundation concrete 40, and the brick column 10 form a stable independent column structure.

[0035] Beneficial effects:

[0036] 1) This independent column structure can effectively avoid the disturbance to the independent brick column that is likely to occur when using the traditional single foundation method, and effectively reduce the construction risk.

[0037] 2) The construction method using this independent column structure can minimize the on-site wet operation to the greatest extent.

[0038] 3) The construction saves low costs, greatly shortens the construction period, is simple to operate, and is safe and reliable.

For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
