They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.
[0024] The terms “first,” “second,” “third,” etc., are used merely to distinguish elements with similar attributes, not to indicate or imply relative importance or a specific order.
[0025] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.
[0026] Example 1
[0027] Please see Figure 1 The built-in buttress column structure provided by the present invention includes a column component 1 and a top beam component 2. The column component 1 is assembled in the height direction of the wall 3, and the top beam component 2 is connected to the column component 1 and is used to be assembled in the width direction of the wall 3.
[0028] Understandably, when repairing a building, especially when replacing the outer wall with a new one, in addition to supporting the existing wall 3, it is also necessary to reinforce the wall 3. This can be achieved by creating grooves along the height of the wall 3 to form an assembly groove, casting a column component 1 in the assembly groove, and casting a top beam component 2 on the top of the wall 3. The top beam component 2 is then connected to the column component 1, thereby strengthening the wall 3.
[0029] Please continue reading. Figure 1 In some embodiments, the column component 1 includes several columns, the top beam component 2 includes several top beams, the several columns are uniformly assembled in the height direction of the wall 3, and the top beams are connected between adjacent columns.
[0030] Understandably, the area requiring reinforcement is determined on wall 3, the columns are evenly distributed along the height of the wall, the top beam is placed at the top of the wall and cast together with the columns.
[0031] Example 2
[0032] Please see Figure 2 This embodiment provides a construction method for an internal buttress column structure, used for the construction of the aforementioned internal buttress column structure, including the following steps:
[0033] S1, determine the reinforcement areas of column member 1 and top beam member 2 on wall 3.
[0034] Understandably, the reinforcement area can be determined based on the damage condition of wall 3.
[0035] S2, Grooving is performed in the reinforced area to form an assembly groove.
[0036] It is understood that the above steps may further include:
[0037] S201, mark lines in the reinforced area to form grooved lines.
[0038] S202, Grooving operation is carried out according to the grooving lines.
[0039] It is understandable that the machine cuts the grooves, while the manual grooving is used to cut the half-brick wall.
[0040] S3, Pop up the layout lines in the reinforced area;
[0041] S4, according to the layout position line, arrange and pour the concrete to form column component 1 and top beam component 2.
[0042] It can be understood that the above steps further include:
[0043] S401, according to the layout position line, column steel bars and top beam steel bars are respectively laid in the assembly slot and the top of the wall 3;
[0044] S402, formwork is made on the column reinforcement and top beam reinforcement and then poured to form column member 1 and top beam member 2.
[0045] Drill holes and install tie bars; lay pipelines, insert tie bars, arrange column reinforcement, then arrange top beam reinforcement, and tie the column reinforcement and top beam reinforcement together; after acceptance, make formwork and pour C30 concrete; concrete curing.
[0046] The precautions to take during the above process include:
[0047] Remove the original plaster layer, scraping away the joints to a depth of 5-10mm. Clean the remaining plaster with a wire brush, blow away any surface dust, moisten with water, and apply a layer of concrete bonding agent. During the plaster removal process, be careful not to apply excessive force to protect the original masonry structure from damage.
[0048] Before planting the tie bars, use an air compressor to clean the dust from the holes, and then clean them with degreased cotton to ensure that there is no dust before proceeding to the next step of construction.
[0049] Before applying the C30 concrete surface layer, the wall surface should be cleaned thoroughly but there should be no standing water.
[0050] After the C30 concrete surface layer is constructed, water curing should be carried out immediately. If high temperatures occur, measures should be taken to cover the wall.
[0051] As can be seen from the above description, the built-in buttress column structure and construction method provided by the present invention reinforce the wall 3 that needs to be repaired, avoid damage to the wall 3 during the repair process, and improve the safety and stability of the repair process.
[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
