Description

Technical Field

[0001] The invention relates to the field of steel pipe column construction, and in particular to a multi-layer one-column steel pipe column ring beam reinforcement construction structure. Background Art

[0002] With the advancement of construction technology, the application of steel pipe columns in building structures has also increased. Steel pipe columns have the advantages of strong bearing capacity, fire resistance and earthquake resistance in structure. Compared with traditional beam-column construction schemes, they have the advantages of convenient construction and short construction period. Therefore, they have been more widely used.

[0003] There is a problem of difficulty in constructing the ring beam reinforcement during the construction of steel pipe columns. Conventional on-site binding construction can be applied to any construction conditions, but the construction period is long and the labor intensity is high, which seriously affects the construction progress. The use of prefabricated ring beam reinforcement and overall hoisting can achieve quick construction and effectively improve construction efficiency. However, the construction method of prefabricated ring beam reinforcement and overall hoisting is only applicable to steel pipe columns with one layer and one column, and there must be no obstacles on the steel pipe column, otherwise the ring beam reinforcement cannot pass through the steel pipe column, and the ring beam reinforcement cannot be hoisted. It cannot be normally applied to special nodes and structures in buildings, and only the technical solution of on-site binding can be adopted, which has an adverse effect on the construction progress. The present invention provides a construction structure of ring beam reinforcement for steel pipe columns with multiple layers and one column to solve the above problems. Summary of the invention

[0004] The present invention provides a multi-layer one-column steel pipe column ring beam reinforcement construction structure, which utilizes pre-installed ring beam reinforcement to avoid the problem of obstruction during hoisting of the ring beam reinforcement and solves the problem of overall hoisting of the ring beam reinforcement at special nodes.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A construction structure of a multi-story single-column steel pipe column ring beam and reinforcement, comprising a constructed structure and a structure to be constructed, wherein the structure to be constructed is located above the constructed structure, wherein the constructed structure comprises a lower steel pipe column, a lower ring beam reinforcement and a cast floor, wherein the ring beam reinforcement is arranged on the upper part of the lower steel pipe column and is located in the cast floor, wherein the structure to be constructed comprises an upper steel pipe column, an upper ring beam reinforcement and a fixing device, wherein the upper steel pipe column is arranged on the lower steel pipe column, wherein in a pre-placed state, the upper ring beam reinforcement is located at the top of the lower steel pipe column, wherein in a construction state, the upper ring beam reinforcement is located on the upper steel pipe column and is located at the position of the cast floor, wherein the fixing device is arranged on the upper steel pipe column and is connected to the upper ring beam reinforcement in the construction state.

[0006] Furthermore, it also includes a construction device, which includes a lifting device, a support frame and a formwork, the support frame is installed on the cast floor, the formwork is installed on the support frame, the upper ring beam steel bars are located on the formwork, and the lifting device is installed above the upper steel pipe column and connected to the upper ring beam steel bars.

[0007] Furthermore, the fixing device comprises unit hangers, the unit hangers are arranged at intervals on the upper steel pipe columns, and the upper ring beam reinforcement is arranged on the unit hangers.

[0008] Furthermore, the lower ring beam reinforcement and the upper ring beam reinforcement are both prefabricated integral reinforcement cages.

[0009] Furthermore, the lifting device includes a hoist and a lifting rope. The hoist is arranged above the upper steel pipe column. The hoist is connected to the upper ring beam steel bars in a pre-placed state through the lifting rope. The lifting ropes are evenly spaced along the circumference of the upper steel pipe column.

[0010] Furthermore, the lower steel pipe column is one column for each layer, the upper steel pipe column is one column for each two layers, and the middle part of the upper steel pipe column passes through the floor to be poured.

[0011] Furthermore, a corbel is provided on the top of the upper steel pipe column.

[0012] Furthermore, the unit hanger is an L-shaped hanger, which is welded to the second steel pipe column.

[0013] The beneficial effects of the present invention are as follows: The prefabricated upper ring beam reinforcement is placed on the top of the lower steel pipe column before the upper steel pipe column is installed. It is not affected by obstacles on the top of the upper steel pipe column. The upper ring beam reinforcement is hoisted to the installation position by the lifting device, and the upper ring beam reinforcement is temporarily fixed by the fixing device. The overall installation of the ring beam reinforcement is achieved when there are obstacles in the steel pipe column, avoiding the use of on-site binding construction methods and the problem of significantly increased construction period.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] The building structure applied by the present invention is that some floors adopt multi-layer one-column steel pipe columns. Under normal working conditions, multi-layer one-column steel pipe columns are mostly used, that is, only the top and bottom of the steel pipe columns are connected to the floors, and the middle part is not connected to the floors. The steel pipe columns of multi-layer one-column are connected to the floors at their top, bottom and middle. For conventional steel pipe columns, whether one-layer one-column or multi-layer one-column, the overall lifting of the ring beam reinforcement can be achieved. However, some building structures are provided with obstacles at the top of the steel pipe columns, such as the presence of a corbel structure at the top of the steel pipe column or the transition of the top steel pipe cylinder to the steel pipe square column. At this time, the overall prefabricated ring beam reinforcement cannot pass through the top of the steel pipe column and cannot be hoisted as a whole. Generally, only the on-site binding method can be used for construction. The on-site binding construction will seriously delay the construction progress. Not only does it need to set up a construction platform, but the progress of on-site binding is slow and the risk is relatively large, which has a greater impact on the construction quality and construction progress. The construction structure of the steel pipe column ring beam reinforcement of a multi-layer one-column of the present invention realizes the overall installation of the ring beam reinforcement for the above working conditions, and ensures the construction progress and construction quality.

[0019] like Figure 1As shown, a specific embodiment of the construction structure of the present invention includes a constructed structure, a structure to be constructed and a construction device, wherein the structure to be constructed is located above the constructed structure, and the construction device is used for the construction of the structure to be constructed, wherein the constructed structure includes a lower steel pipe column 1, a lower ring beam reinforcement 2 and a cast floor 3, wherein the ring beam reinforcement 2 is arranged on the upper part of the lower steel pipe column 1 and is located in the cast floor 3, wherein the structure to be constructed includes an upper steel pipe column 4, an upper ring beam reinforcement 5 and a fixing device 6, wherein the upper steel pipe column 4 is arranged on the lower steel pipe column 1, and in a pre-placed state, the upper ring beam reinforcement 5 is located at the top of the lower steel pipe column 1 In the construction state, the upper ring beam reinforcement 5 is lifted to the upper steel pipe column 4 by the lifting device 7, and fixed on the upper steel pipe column 4 by the fixing device 6, and is located at the position of the floor to be poured on the upper steel pipe column 4. The fixing device 6 is arranged on the upper steel pipe column 4 and is connected to the upper ring beam reinforcement 5 in the construction state; the construction device includes a lifting device 7, a support frame 8 and a template 9. The support frame 8 is arranged on the poured floor 3, the template 9 is arranged on the support frame 8, the upper ring beam reinforcement 5 is located on the template 9, and the lifting device 7 is arranged above the upper steel pipe column 4 and is connected to the upper ring beam reinforcement 5.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, the upper steel pipe column 4 in this embodiment is a steel pipe column with two layers and one column, and its bottom, middle and top all need to be connected to the floors, and the bottom floor is the poured floor 3. After the upper steel pipe column 4 is installed, ring beam reinforcements need to be set in the middle and top. The ring beam reinforcement located at the top of the upper steel pipe column 4 can be hoisted as a whole by a crane, but the ring beam reinforcement located in the middle of the upper steel pipe column 4 cannot be hoisted as a whole due to the obstruction of the corbel. The traditional operation method is to perform on-site binding of the upper ring beam reinforcement 5 in the middle of the upper steel pipe column 4, while in this embodiment, the upper ring beam reinforcement 5 is first prefabricated and pre-placed on the top of the lower steel pipe column 1, and then the upper steel pipe column 4 is installed. After the upper steel pipe column 4 is installed, the upper ring beam reinforcement 5 is lifted upward to the middle part of the upper steel pipe column 4 by the lifting device 7, and then the upper ring beam reinforcement 5 is fixed to the upper steel pipe column 4 by the fixing device 6, and then the support frame 8 and the template 9 are supported, and finally the concrete pouring construction of the floor to be poured is carried out. This embodiment achieves the overall placement of the upper ring beam reinforcement 5 by pre-placing the upper ring beam reinforcement 5 to avoid obstruction of the upper steel pipe column 4, and achieves the installation and construction of the upper ring beam reinforcement 5 by hoisting and lifting by the lifting device 7 and temporary fixation by the fixing device 6. The purpose of constructing the overall prefabricated upper ring beam reinforcement 5 on the upper steel pipe column 4 with obstacles is achieved through the above-mentioned construction structure, which effectively improves the construction efficiency and construction quality.

[0021] like Figure 5 , 6As shown, further, the fixing device 6 includes a unit hanger 61 , and the unit hangers 61 are arranged on the upper steel pipe column 4 at intervals, and the upper ring beam reinforcement 5 is arranged on the unit hanger 61 .

[0022] Furthermore, the lower ring beam reinforcement 2 and the upper ring beam reinforcement 5 are both prefabricated integral reinforcement cages.

[0023] Furthermore, the lifting device 7 includes a hoist and a lifting rope. The hoist is arranged above the upper steel pipe column 4. The hoist is connected to the upper ring beam reinforcement 5 in a pre-placed state through the lifting rope. The lifting rope is evenly spaced along the circumference of the upper steel pipe column 4.

[0024] Furthermore, the lower steel pipe column 1 has one column for each layer, the upper steel pipe column 4 has one column for each two layers, and the middle portion of the upper steel pipe column 4 passes through the floor to be cast.

[0025] Furthermore, a corbel is provided at the top of the upper steel pipe column 4 , or the top of the upper steel pipe column 4 transitions from a steel pipe round column to a steel pipe square column. The above situations result in that the prefabricated upper ring beam reinforcement 5 cannot pass through the top of the upper steel pipe column 4 .

[0026] Furthermore, the unit hanger 61 is an L-shaped rod or plate, which is welded to the second steel pipe column 3. The length of the hanging end of the unit hanger 61 is 500 mm, and the length of the welding end is 800 mm. It is evenly spaced on the outer wall of the upper steel pipe column 4, and a total of 8 units are set to fix the upper ring beam steel bars 5 so that the upper ring beam steel bars 5 can be stably placed on the floor to be cast of the upper steel pipe column 4.

[0027] like Figure 2 , 3 As shown, when this embodiment is constructed, the specific construction steps are as follows: First, install the lower steel pipe column 1, support the support frame 8 and the formwork 9, and then hoist the prefabricated lower ring beam reinforcement 2 to the top of the lower steel pipe column 1 by a crane and tie it up, and then perform the concrete pouring construction of the poured floor 3; Second, the prefabricated upper ring beam reinforcement 5 is placed on the top of the lower steel pipe column 1, and then the upper steel pipe column 4 is installed; Third, support frames 8 and formwork 9 are installed on the poured floor 3 as the construction work surface of the floor to be poured. When the construction work surface is installed, a lifting space for the upper ring beam reinforcement 5 is reserved; Fourth, install a lifting device 7 on the top of the upper steel pipe column 4, connect the lifting device 7 to the upper ring beam reinforcement 5, and then lift the upper ring beam reinforcement 5 upward along the upper steel pipe column 4 through the lifting device 7 to the position of the upper steel pipe column 4 on the floor to be poured, and keep it stable; Fifth, install the fixing device 6 on the construction work surface, temporarily fix the upper ring beam reinforcement 5 on the upper steel pipe column 4 through the fixing device 6, then release the connection between the lifting device 7 and the upper ring beam reinforcement 5, and remove the lifting device 7; Sixth, fill the reserved space on the construction work surface, then carry out the binding construction of the upper ring beam reinforcement 5 and the floor reinforcement, and finally carry out the concrete pouring construction of the floor to be poured.

[0028] Conventionally, the upper ring beam reinforcement 5 is fixed by supporting with a support frame 8 and a formwork 9, and the support frame 8 and the formwork 9 are erected on the poured floor 3. After erection, the upper ring beam reinforcement 5 cannot be lifted. Therefore, a fixing device 6 is used to temporarily fix the upper ring beam reinforcement 5. However, the fixing device 6 is installed after the upper ring beam reinforcement 5 is lifted into place, and high-altitude operation is required. Therefore, a part of the support frame 8 and the formwork 9 are first supported, and a lifting path for the upper ring beam reinforcement 5 is reserved. The supported support frame 8 and the formwork 9 are used as the working surface to install the fixing device 6. After the upper ring beam reinforcement 5 is lifted into place, the fixing device 6 is installed and the upper ring beam reinforcement 5 is temporarily fixed, and then the support frame 8 and the formwork 9 are completed.

[0029] The structure of this embodiment and the corresponding construction method significantly improve the construction convenience and efficiency, and reduce the demand for working surfaces. It solves the construction problem of ring beam reinforcement in special structures without adding construction facilities, and realizes the overall installation of ring beam reinforcement under special working conditions, simplifies construction operations, and improves installation efficiency and construction quality.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any reference numerals in the claims should not be regarded as limiting the claims involved.
