Description

Technical Field

[0001] This invention relates to the field of steel structure short column technology, specifically a construction method for connecting cross-shaped steel columns with concrete beams and columns. Background Technology

[0002] Currently, in the steel structure construction process, starting from the construction surface, short columns need to be installed as the main steel structure pre-components of the load-bearing wall. On this basis, the entire wall construction is completed.

[0003] Regarding the aforementioned technologies, it has been found that while existing short column structures are simple, multiple layers of short columns are required during actual construction and installation, resulting in higher construction costs. Summary of the Invention

[0004] In order to reduce the number of short columns used and lower construction costs, this application provides a construction method for connecting cross-shaped steel columns with concrete beams and columns.

[0005] This invention is implemented as follows:

[0006] A cross-shaped steel column includes a base, which comprises a base plate and a base frame. The base frame is disposed on the lower end face of the base plate and is fixedly connected to the base plate. A top frame is installed on the upper end face of the base plate and is fixedly connected to the base plate. A side extension frame is installed on the outer side of the top frame. The side extension frame includes a horizontal plate, a vertical frame, and a bent plate. The horizontal plate is fixedly installed on the outer side face of the base plate. The vertical frame is fixedly installed on the upper end face of the horizontal plate. The bent plate is fixedly installed on the upper end face of the vertical frame. Both the vertical frame and the bent plate are welded and fixed to the outer side face of the top frame.

[0007] By adopting the above technical solution, the base structure is designed to ensure that the seat plate can be pre-embedded through the lower base frame. After the base frame is cast and fixed, it can stably support the seat plate. At the same time, a top frame is installed on the upper surface of the seat plate to ensure greater stability during the upper part of the casting process. Side extension frames are installed on the outer side of the top frame to facilitate the extension and binding of steel reinforcement structures in different directions. Steel reinforcement is then used to assist in the casting and fixing. In this way, reinforced concrete can be used as the corresponding support arms around the perimeter, eliminating the need for multiple short column structures for positioning and installation, thereby increasing construction efficiency and saving costs. The side extension frame structure is designed to ensure that the horizontal plate and the bent plate can be fixedly connected to each other through the vertical frame, ensuring the overall effect between the two. At the same time, one end of the horizontal plate, the vertical frame, and the bent plate can be welded and fixed to the outer side of the top frame to ensure the overall stability of the side extension frame and facilitate the subsequent binding of steel reinforcement.

[0008] Furthermore, a positioning block for mounting the top frame is provided at the center of the upper surface of the seat plate. The positioning block is fixedly connected to the seat plate, and a number of positioning slots for mounting the horizontal plate are evenly provided along the circumferential direction on the outer side of the seat plate.

[0009] By adopting the above technical solution, a positioning block is set at the center of the upper surface of the base plate, which facilitates the stable placement of the top frame. This makes it easier for the top frame to be stably welded and fixed on the upper surface of the base plate. At the same time, the positioning slot facilitates better positioning and installation of the horizontal plate, making it easier to weld the horizontal plate after it is inserted into the positioning slot.

[0010] Furthermore, the base frame includes a flange and anchor bolts. The anchor bolts are evenly arranged on the flange and are fixedly connected to the flange. The heads of the anchor bolts pass through the base plate and are fixedly connected to the base plate.

[0011] By adopting the above technical solution, the structure of the base frame is designed to ensure that the flanges are used to install the anchor bolts, thereby connecting the anchor bolts together and facilitating their stability during use.

[0012] Furthermore, the top frame includes a middle frame and an outer panel, the outer panel being evenly distributed on the outer side of the middle frame and fixedly connected to the middle frame.

[0013] By adopting the above technical solution, the structure of the top frame is designed to ensure that the outer panel is fixedly installed through the middle frame, and the inner side of the outer panel can be fixedly installed on the middle frame, and the lower end of the outer panel is welded and fixed to the upper end of the base plate.

[0014] Furthermore, the middle frame is configured as a cross-shaped structure, with its lower end installed in a positioning block, and the middle frame is fixedly connected to the positioning block.

[0015] By adopting the above technical solution and setting the middle frame as a cross-shaped structure, it is convenient to fix and install a corresponding outer panel at each end of the middle frame.

[0016] Furthermore, a reinforcing frame is installed between the outer panels, with both ends of the reinforcing frame fixedly installed on the inner sides of the two outer panels respectively.

[0017] By adopting the above technical solution and installing reinforcing frames between the outer panels, the outer panels can be made more stable during actual construction.

[0018] Furthermore, a plurality of first anchors are evenly arranged on the outer plate, and the first anchors are vertically fixed to the outer plate.

[0019] By adopting the above technical solution, several first anchors are evenly set on the outer plate, which makes it easier to place the reinforcing bars on the first anchors, and then the reinforcing bars can be bound by steel wire.

[0020] Furthermore, several horizontal plates are symmetrically installed on both sides of the vertical frame. The horizontal plates are vertically fixed to the vertical frame, and several second anchors are also provided on the horizontal plates. Positioning holes are also provided on the vertical frame.

[0021] By adopting the above technical solution, several horizontal plates are symmetrically installed on both sides of the vertical frame, which can be used to increase the overall strength of the side extension frame. This facilitates the use of longer lapped steel bars. At the same time, by opening several positioning holes on the vertical frame, steel bars can pass through the vertical frame to achieve the purpose of auxiliary support and fixation of the steel bars.

[0022] A construction method for a cross-shaped steel column includes the following steps:

[0023] S1: Pre-embedded anchor bolts;

[0024] S2: Concrete column and concrete beam pouring;

[0025] S3: Short column structure installation;

[0026] S4: Column reinforcement through-hole steel bar sleeve connection;

[0027] S5: Beam reinforcement binding and welding;

[0028] S6: Concrete pouring for beams and columns.

[0029] The installation method for the short column structure in S3 is as follows: place the base plate on the head of the anchor bolt, adjust the appropriate height, and then weld it in place.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: This application designs a short column structure of a steel structure, which facilitates initial casting and fixing during actual construction and use, and then achieves overall installation and use through the base plate, making construction and operation easier. At the same time, by fixing and installing several side extension frames around the top frame, after the base and top frame are fixedly installed, the side extension frames can be used to bind the extended steel bars, and then the extended steel bars can be cast to form the corresponding wall. This can greatly reduce the number of traditional short columns used. The new short column structure replaces the use of short columns below the second floor, and instead uses steel bars for positioning and casting. Short columns are then connected from the second floor onwards, thereby reducing construction costs. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0041] Reference Figure 1 , Figure 2 and Figure 3 As shown, a cross-shaped steel column includes a base 1, which includes a base plate 11 and a base frame 12. The base frame 12 is located on the lower end face of the base plate 11 and is fixedly connected to the base plate 11. A top frame 2 is installed on the upper end face of the base plate 11 and is fixedly connected to the base plate 11. The structure of the base 1 ensures that the base plate 11 can be pre-embedded by the lower end of the base frame 12. After the base frame 12 is cast and fixed, it can stably support the base plate 11. At the same time, by installing the top frame 2 on the upper end face of the base plate 11, it is convenient to ensure greater stability when the upper end is cast. Furthermore, by installing side extension frames 3 on the outer side of the top frame 2, it is convenient to extend and bind steel reinforcement structures in different directions through the side extension frames 3 around the perimeter. Then, it is convenient to use steel reinforcement for auxiliary casting and fixing. In this way, the surrounding area can be supported by reinforced concrete, eliminating the need for multiple short column structures to be coordinated and positioned, thereby increasing construction efficiency and saving costs.

[0042] Reference Figure 3 and Figure 4 As shown, a positioning block 111 for mounting the top frame 2 is provided at the center of the upper surface of the base plate 11. The positioning block 111 is fixedly connected to the base plate 11, and a plurality of positioning slots 112 for mounting the horizontal plate 31 are evenly provided along the circumferential direction on the outer side of the base plate 11. By providing a positioning block 111 at the center of the upper surface of the base plate 11, the top frame 2 can be stably placed by the positioning block 111, making it easier for the top frame 2 to be stably welded and fixed on the upper surface of the base plate 11. At the same time, the positioning slots 112 facilitate better positioning and installation of the horizontal plate 31, making it easier for the horizontal plate 31 to be welded after being inserted into the positioning slots 112.

[0043] Reference Figure 3 and Figure 4 As shown, the base frame 12 includes a flange 121 and anchor bolts 122. The anchor bolts 122 are evenly arranged on the flange 121 and are fixedly connected to the flange 121. The heads of the anchor bolts 122 pass through the base plate 11 and are fixedly connected to the base plate 11. The structural design of the base frame 12 ensures that the anchor bolts 122 are installed on the flange 121, thereby connecting the anchor bolts 122 together and facilitating the stability of the anchor bolts 122 during use.

[0044] Reference Figure 2 and Figure 3As shown, the top frame 2 includes a middle frame 21 and an outer plate 22. The outer plates 22 are evenly distributed on the outer side of the middle frame 21 and are fixedly connected to the middle frame 21. The structural design of the top frame 2 ensures that the outer plates 22 are fixedly installed via the middle frame 21, and that the inner side of the outer plates 22 can be fixedly installed on the middle frame 21. The lower end of the outer plates 22 is welded and fixed to the upper surface of the base plate 11. The middle frame 21 is configured with a cross-shaped structure, and its lower end is installed in the positioning block 111, with the middle frame 21 fixedly connected to the positioning block 111. By configuring the middle frame 21 with a cross-shaped structure, it is convenient to fix a corresponding outer plate 22 at each end of the middle frame 21.

[0045] Reference Figure 2 and Figure 3 As shown, a reinforcing frame 23 is also installed between the outer plates 22, with both ends of the reinforcing frame 23 fixedly installed on the inner sides of the two outer plates 22 respectively. By installing the reinforcing frame 23 between the outer plates 22, the stability of the outer plates 22 can be ensured during actual construction. Several first anchor nails 221 are evenly arranged on the outer plates 22, and the first anchor nails 221 are vertically fixed to the outer plates 22. By evenly arranging several first anchor nails 221 on the outer plates 22, it is convenient to place the reinforcing bars on the first anchor nails 221, and then bind the reinforcing bars with steel wire.

[0046] Reference Figure 5 and Figure 6 As shown, a side extension frame 3 is installed on the outer side of the top frame 2. The side extension frame 3 includes a horizontal plate 31, a vertical frame 32, and a bent plate 33. The horizontal plate 31 is fixedly installed on the outer side of the base plate 11, the vertical frame 32 is fixedly installed on the upper end face of the horizontal plate 31, and the bent plate 33 is fixedly installed on the upper end face of the vertical frame 32. Both the vertical frame 32 and the bent plate 33 are welded and fixed to the outer side of the top frame 2. The structural design of the side extension frame 3 ensures that the horizontal plate 31 and the bent plate 33 can be fixedly connected to each other through the vertical frame 32, ensuring the overall effect between the two. At the same time, one end of the horizontal plate 31, the vertical frame 32, and the bent plate 33 can be welded and fixed to the outer side of the top frame 2, ensuring the overall stability of the side extension frame 3 and facilitating the later binding of reinforcing bars.

[0047] Reference Figure 5 and Figure 6As shown, several horizontal plates 321 are symmetrically installed on both sides of the vertical frame 32. The horizontal plates 321 are vertically and fixedly connected to the vertical frame 32, and several second anchors 322 are also provided on the horizontal plates 321. Positioning holes 323 are also provided on the vertical frame 32. By symmetrically installing several horizontal plates 321 on both sides of the vertical frame 32, the overall strength of the side extension frame 3 is increased through the horizontal plates 321, which facilitates the use of longer lapped steel bars. At the same time, by providing several positioning holes 323 on the vertical frame 32, the steel bars can pass through the vertical frame 32 to achieve the purpose of auxiliary support and fixation of the steel bars.

[0048] Reference Figure 1 and Figure 7 As shown, a construction method for a cross-shaped steel column is characterized by the following steps: S1: pre-embedded anchor bolts → S2: concrete column and beam pouring → S3: short column structure installation → S4: column reinforcement through-hole steel sleeve connection → S5: beam reinforcement binding and welding → S6: beam and column concrete pouring. The short column structure installation method in S3 involves: placing a base plate on the head of the anchor bolt, adjusting the height accordingly, and then welding it in place. This allows for easy adjustment of the installation height according to actual needs.

[0049] Working principle: Four L-shaped plain round steel bars are fixed in place. The second layer uses flanges to fix four anchor bolts, serving a positioning function. Steel bars are installed around the four main steel bars at specified intervals. Six shorter steel bars pass through pre-drilled holes in the corbel to connect to the corbel, which is integrated with the steel column. All steel bars are bound together with steel wire to form a square column steel structure. Then, the concrete is poured to 100mm below the beam bottom. The reserved steel bars are connected to the base plate, and are linked or welded to the inserted steel bars using the first and second anchor bolts around the perimeter. After all the steel bars are bound, the entire structure can be poured to complete the construction.
