Description

Technical Field

[0001] The present invention relates to the technical field of box-type steel column construction, and in particular to an embedded box-type steel column installation device and a construction method thereof. Background Art

[0002] Box-shaped steel columns embedded in the concrete foundation not only improve the structure's bearing capacity and stability, but also optimize building space, comply with environmental protection requirements, and provide additional underground space. These advantages have led to their widespread use in industrial buildings. Traditionally, the positioning and temporary fixation of box-shaped steel columns during installation involves first installing fixed brackets at the base of the foundation, then using a crane to lift the steel columns to the desired location. After verifying their position, the steel columns are welded to the brackets. This traditional approach presents challenges with pre-embedded steel columns, as well as the need to embed fixed brackets within the foundation, which increases construction costs. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an embedded box-type steel column installation device and a construction method thereof, so as to solve the problems in the prior art of difficult positioning of box-type steel columns, inconvenient installation of built-in brackets, and increased costs.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0008] The hoisting assembly and the supporting assembly can be connected to the box-type steel column simultaneously or selectively.

[0009] Furthermore, a cavity is formed in the bearing seat, which is closed on all sides and open at two opposite ends, for accommodating the first lifting structure;

[0010] A mounting groove is formed outside the bearing seat for accommodating the second lifting structure.

[0011] Furthermore, the first lifting structure includes: a slider and a first sling, the slider is slidably arranged in the cavity and connected to the first sling, and the two ends of the first sling extend to the two open ends of the cavity respectively to form two first lifting nodes.

[0012] Furthermore, the cavity is provided with a driving member for driving the slider to slide back and forth along the two open ends of the cavity.

[0013] Furthermore, the cavity is provided with a guide rod along the sliding direction of the slider, and the slider is slidably sleeved on the guide rod.

[0014] Furthermore, the bearing seat is rotatably provided with two guide wheels, and the two guide wheels are respectively located at the two open ends of the cavity and are rotatably fitted with the first sling.

[0015] Furthermore, the second lifting structure includes a rotating disk and a second lifting cable. The rotating disk is rotatably mounted in the mounting slot and is provided with a partition plate. The partition plate divides the rotating disk into two winding bins spaced apart along its axial direction. The second lifting cable has two connected connecting segments. The proximal ends of the two connecting segments are respectively wound around the two winding bins in opposite directions. The distal ends of the two connecting segments respectively form two second lifting nodes. The connection point of the two connecting segments is fixed to the partition plate. When the rotating disk rotates, one of the two second lifting nodes is released and the other is tightened.

[0016] Furthermore, the partition is provided with a through hole for connecting the two winding bins, and the connection point of the two connecting sections is passed through and fixed to the through hole.

[0017] Furthermore, a hinge point is formed at the connection between the hoop and the first support rod, and at the connection between the first support rod and the second support rod; and / or

[0018] The telescopic structure is a plurality of turnbuckle bolts.

[0019] The construction method of the embedded box-type steel column installation device described above includes the following steps:

[0020] Installing the first lifting node and the second lifting node along two diagonal lines on the upper surface of the box-shaped steel column;

[0021] Hoisting the box-shaped steel column to a predetermined position on the foundation, and synchronously adjusting the hoisting lengths of the two first hoisting nodes; and / or synchronously adjusting the hoisting lengths of the two second hoisting nodes to control the initial verticality of the box-shaped steel column and to allow the box-shaped steel column to hover until it slightly touches the bottom;

[0022] Installing the hoop along the outer surface of the box-shaped steel column, and adjusting the lengths of the first support rod and the second support rod through the corresponding telescopic structure to match the initial verticality;

[0023] Fixing the first support rod and releasing the lifting assembly;

[0025] After the box-type steel columns are cast, the support components are removed.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The first hoisting structure and the second hoisting structure form two first hoisting nodes and two second hoisting nodes, respectively, so that the first hoisting structure can control one pair of diagonal nodes, and the second hoisting structure can control the other pair of diagonal nodes. The two groups can independently and synchronously adjust the hoisting length. By adjusting the length difference between the two groups of diagonal nodes, the verticality of the box-type steel column can be roughly adjusted to ensure that it can fall into the foundation and improve the positioning accuracy of the box-type steel column. Furthermore, one of the two hoisting nodes can follow the movement of the other, and a single adjustment can ensure the position accuracy of a pair of diagonal nodes.

[0028] 2. The hoop is set on the outer surface of the box-shaped steel column, and the first support rod provides the main anti-overturning force, and the first support rod and the second support rod form a rigid spatial triangular grid structure, which enhances the stability of the box-shaped steel column after hoisting and during concrete pouring. At the same time, the external support assembly can be reused, saving costs. Furthermore, a telescopic structure is set at the first support rod and the second support rod, and the length of the corresponding support rod can be adjusted through the telescopic structure. Therefore, by finely adjusting the length of each support rod, the verticality of the box-shaped steel column can be fine-tuned and corrected, thereby improving its positioning accuracy.

[0029] 3. When the box-type steel column is suspended in a bottoming state using the lifting assembly and used in conjunction with the support assembly, the support assembly can match the initial verticality adjusted by the lifting assembly, and then use the support assembly for final correction to achieve rough positioning during the lifting process and precise positioning before embedding. The verticality of the box-type steel column is not easy to change when the two components are connected; at the same time, after removing the lifting assembly during the pouring stage, the support assembly is retained at the box-type steel column, which can provide a stable support for it and avoid the verticality after correction from being destroyed again.

[0044] The present invention will be further described in detail below through specific embodiments:

[0045] In the embodiment of the present invention, Figure 1-Figure 7 As shown, the embedded box-type steel column installation device includes: a lifting component and a support component 4;

[0046] The hoisting assembly includes: a bearing seat 1, a first hoisting structure 2 and a second hoisting structure 3, wherein the first hoisting structure 2 and the second hoisting structure 3 are independently arranged on the bearing seat 1, and are respectively formed with two first hoisting nodes 201 and two second hoisting nodes 301, the two first hoisting nodes 201 and the two second hoisting nodes 301 are all diagonally arranged to be distributed on the two diagonals of the upper surface of the box-shaped steel column, and under the action of external force, the hoisting lengths of the two first hoisting nodes 201 can be synchronously adjusted so that the hoisting lengths of the two are equal or one of them changes gradually with the other, and / or the hoisting lengths of the two second hoisting nodes 301 can be synchronously adjusted so that the hoisting lengths of the two are equal or one of them changes gradually with the other;

[0047] The support assembly 4 includes: a hoop 401, a plurality of first support rods 402 and a plurality of second support rods 403. The hoop 401 is detachably mounted on the outer surface of the box-shaped steel column. The plurality of first support rods 402 are arranged at intervals and tilted on the circumference of the hoop 401. Adjacent first support rods 402 are connected by the second support rods 403. The first support rods 402 and the second support rods 403 are provided with telescopic structures 404 along their respective length directions for adjusting the length of the corresponding first support rods 402 or the second support rods 403.

[0048] The hoisting assembly and the supporting assembly 4 can be connected to the box-type steel column simultaneously or selectively.

[0049] Specifically, in an embodiment of the present invention, the lifting assembly includes a bearing seat 1, a first lifting structure 2 and a second lifting structure 3. Both lifting structures are arranged at the bearing seat 1 and are independent of each other; thus, two groups of lifting that do not interfere with each other can be formed to jointly lift box-type steel columns (hereinafter referred to as "steel columns").

[0050] Specifically, the first hoisting structure 2 has two first hoisting nodes 201 arranged diagonally, and the second hoisting structure 3 has two second hoisting nodes 301 arranged diagonally; since there are two diagonals on the upper surface of the steel column, the above-mentioned two first hoisting nodes 201 are arranged at one diagonal of the steel column, and the two second hoisting nodes 301 are arranged at the other diagonal, so that the steel column is lifted by each hoisting node. At the same time, due to the independent arrangement of the two hoisting structures, the hoisting nodes do not interfere with each other, and there will be no crossing or knotting. Of course, in order to facilitate hoisting, corresponding lifting ears can be set on the upper surface of the bearing seat 1 and the steel column, which will not be described in detail here.

[0051] In addition, in order to be able to roughly adjust the verticality of the steel column during the hoisting process so that it can be closer to the preset angle and position when it falls into the foundation; the two first hoisting nodes 201 in this embodiment can be adjusted under the action of an external force so that the hoisting lengths of the two first hoisting nodes 201 are equal or unequal, that is, the heights of the two first hoisting nodes 201 are located in the same plane or in two different planes. The hoisting lengths of the two first hoisting nodes 201 are changed according to actual conditions to adjust the positions of the two diagonal corners of the steel column. Similarly, the hoisting lengths of the two second hoisting nodes 301 can also be adjusted under the action of an external force to adjust the positions of the diagonal corners of the steel column connected to the second hoisting nodes 301. Thus, the dual hoisting adjustment mode can be adjusted step by step or synchronously, thereby roughly adjusting the verticality of the steel column during the hoisting process, improving its positioning accuracy, and making it simple and reliable to operate. Furthermore, taking the first hoisting node 201 as an example, if the hoisting length of one of the two first hoisting nodes 201 is changed, the other will also change accordingly. For example: if one hoisting length gradually increases, the other hoisting length will gradually decrease; therefore, the diagonal principle can be used to adjust the angle of the steel column to improve the adjustment efficiency. Of course, since the hoisting length of the hoisting node can be changed, even if the upper surface of the steel column is tilted or uneven, the steel column can be kept at a preset angle by adjusting the hoisting length of the hoisting node. Therefore, the hoisting assembly in this embodiment can be used for adjusting the angle of the steel column during the hoisting process, and can also be adaptively adjusted based on the unevenness of the upper surface of the steel column itself, so that it can be flexibly used in various construction scenarios.

[0052] In the embodiment of the present invention, the support assembly 4 includes a hoop 401, a first support rod 402 and a second support rod 403. The hoop 401 is detachably mounted on the outer surface of the steel column, and its inner surface is adapted to the outer surface of the steel column. In order to facilitate installation, the hoop 401 can adopt a spliced ​​structure; or in order to facilitate improving the structural strength of the hoop 401, it can be an integrated structure; and it can adopt an inner and outer or upper and lower double-layer structure, which is not limited here. A plurality of first support rods 402 (such as Figure 7As shown, this embodiment takes four first support rods 402 as an example), and the first support rods 402 are arranged on the ground at an angle of 45°, so as to construct a spatial triangular support system (during installation, a corresponding number of embedded parts can be set on the ground, and the first support rods 402 are fixed to the ground using the embedded parts). Furthermore, a second support rod 403 is set between two adjacent first support rods 402, so as to improve the overall structural strength of the support assembly 4 and enhance the stability of the steel column after hoisting and during the pouring of concrete. That is: after hoisting or during the pouring of concrete, the support assembly 4 is used to position the steel column to avoid its displacement. At the same time, replacing the traditional built-in support structure with the external support assembly 4 in this embodiment can not only ensure the stability of the steel column, but also can be dismantled and reused after the construction is completed, saving costs.

[0053] Furthermore, to precisely position the verticality of the steel column using the support assembly 4, the first and second support rods 402, 403 are each provided with a telescopic structure 404 that can extend and retract along the length of the corresponding support rod to change the length of the support rod, thereby enabling fine adjustment of the position and angle of the steel column by adjusting the length of the corresponding support rod. Furthermore, to match the initial verticality after the hoisting assembly's rough adjustment, fine adjustment is performed based on this initial verticality. In this embodiment, when the hoisting assembly hoists the steel column until it hovers above the concrete foundation, the verticality of the steel column is the initial verticality adjusted by the hoisting assembly. The support assembly 4 is installed on the outer surface of the steel column, and the corresponding telescopic structure 404 is adjusted to extend and retract based on the initial verticality, changing the length of the corresponding support rod. The initial verticality is then switched from being controlled by the hoisting assembly to being controlled by the support assembly 4, and the hoisting assembly is released. Finally, the corresponding telescopic structure 404 is adjusted again to fine-tune or correct the verticality of the steel column to complete the positioning and installation of the steel column.

[0054] This embodiment uses the coarse adjustment positioning of the lifting component and the fine adjustment positioning of the support component 4 to achieve accurate positioning of the steel column by lifting and pre-embedding the steel column so that it can meet the preset installation position; furthermore, the adjustable lifting components can be adjusted simultaneously or independently, which not only increases the adjustment range of the steel column angle, but also avoids interference with the lifting process due to unevenness on the upper surface of the steel column; at the same time, the use of an external support component 4 is not only convenient for installation, but also can be reused after dismantling, saving costs.

[0055] like Figure 2-Figure 4As shown, in one embodiment, a cavity 101 is formed within the support base 1, which is closed on all sides and open at two opposite ends, for accommodating the first lifting structure 2; a mounting groove 102 is formed on the outside of the support base 1, for accommodating the second lifting structure 3. Specifically, to prevent interference between the two lifting structures, this embodiment provides a cavity 101 inside the support base 1 and a mounting groove 102 on its outer surface, so that the first lifting structure 2 and the second lifting structure 3 can be independently installed in the cavity 101 and the mounting groove 102 of the support base 1, respectively. In addition, the cavity 101 is configured to be closed on all sides and open at two opposite ends, so that the two first lifting nodes 201 can be respectively arranged at the two open ends of the cavity 101; and the two second lifting nodes 301 can be respectively arranged at the front and rear ends of the support base 1. In this way, the four lifting nodes do not affect each other, and their lifting lengths can be changed according to actual conditions when adjusting external forces. In this way, the two lifting structures can be installed to the same component through the same support base 1, and only the support base 1 needs to be lifted during lifting, making the operation more convenient.

[0056] like Figure 2-Figure 5 As shown, in one embodiment, the first lifting structure 2 includes: a slider 202 and a first sling 203. The slider 202 is slidably provided in the cavity 101 and is connected to the first sling 203. The two ends of the first sling 203 extend respectively to the two open ends of the cavity 101 and form two first lifting nodes 201. Specifically, in order to make one of the two first lifting nodes 201 correspond to the other and follow its changes; this embodiment defines that the first lifting structure 2 includes a slider 202 and a first sling 203. The slider 202 can slide back and forth in the cavity 101 under the action of external force, and the slider 202 is provided with a through hole for fixing the first sling 203; the two ends of the first sling 203 extend respectively to the two open ends of the cavity 101 to form two first lifting nodes 201. In this way, when the slider 202 slides toward one of the open ends, it can pull the first sling 203 to move, thereby changing the lifting lengths of the two first lifting nodes 201, making them equal, or setting one longer and one shorter. Furthermore, since the two first lifting nodes 201 are actually the two ends of the same first sling 203, the heights of the two first lifting nodes 201 can be changed as the first sling 203 moves with the slider 202, thereby allowing the sliding of the slider 202 to quickly adjust the angle of the steel column after being lifted by the first lifting node 201.

[0057] Preferably, the cavity 101 is provided with a driving member for driving the slider 202 to slide back and forth along the two open ends of the cavity 101. The driving member mentioned above can be a jack, a screw assembly, etc. Figure 4As shown, in this embodiment, a screw is rotatably provided in the cavity 101, and the screw is driven by a motor (not shown) in the cavity 101. The slider 202 is sleeved on the screw to utilize the forward and reverse rotation of the screw to cause the slider 202 to slide between the two open ends of the cavity 101.

[0058] Preferably, Figure 5 As shown, in one embodiment, the cavity 101 is provided with a guide rod 5 along the sliding direction of the slider 202, and the slider 202 is slidably mounted on the guide rod 5. Specifically, in order to improve the stability of the slider 202 and enable it to pull the first sling 203 for synchronous movement, this embodiment provides a guide rod 5 within the cavity 101. The guide rod 5 is fixed by a base so that it is suspended within the cavity 101, and the guide rod 5 is arranged along the sliding direction of the slider 202. After the slider 202 is mounted on the guide rod 5, the guide rod 5 can guide and position the slider 202, so that the slider 202 is subjected to a balanced force and can slide along a preset path.

[0059] Preferably, Figure 2-Figure 5 As shown, in one embodiment, the support base 1 is rotatably provided with two guide wheels 6, which are respectively located at the two open ends of the cavity 101 and rotatably engage with the first sling 203. Specifically, in order to reduce or avoid jamming of the two first lifting nodes 201 during adjustment, this embodiment provides two mounting seats at the two open ends of the cavity 101, and the two guide wheels 6 are rotatably disposed at the two mounting seats, so that the first sling 203 can be disposed in the grooves of the corresponding guide wheels 6 to guide and constrain the first sling 203.

[0060] like Figure 6 As shown, in one embodiment, the second lifting structure 3 includes: a rotating disk 302 and a second sling 303, the rotating disk 302 is rotatably arranged in the installation groove 102, and is provided with a partition 304, the partition 304 divides the rotating disk 302 into two winding bins spaced apart along its axial direction, the second sling 303 has two connected connecting sections, the proximal ends of the two connecting sections are respectively wound around the two winding bins in opposite directions, and the distal ends of the two respectively form two second lifting nodes 301, and the connection between the two connecting sections is fixed to the partition 304, so as to release one of the two second lifting nodes 301 and tighten the other one of the two when the rotating disk 302 rotates.

[0061] Specifically, the middle part of the rotating disk 302 is a hollow cylindrical structure, and an annular stopper is provided at both ends thereof, so that the middle part of the rotating disk 302 can be rotatably sleeved on the mounting groove 102 of the bearing seat 1. In order to adapt to the shape of the rotating disk 302 and enable the rotating disk 302 to rotate around the axis of the middle part, as shown in FIG. Figure 3 、 Figure 5 As shown, the mounting groove 102 in this embodiment is annular in structure and is not connected to the cavity 101. The inner wall of the mounting groove 102 can rotatably engage the annular stopper of the rotating disk 302, thereby limiting the rotating disk 302 to rotation without axial displacement. Furthermore, a partition 304 is provided in the middle of the rotating disk 302. This partition 304 is also annular in structure and is used to divide the rotating disk 302 into two winding bins. Specifically, the space between the partition 304 and one of the stops forms a first winding bin 305, and the space between the partition 304 and the other stop forms a second winding bin 306.

[0062] The second sling 303 has two connected sections, namely a first section and a second section. The first section and the second section are respectively wound around the first winding bin 305 and the second winding bin 306, with their winding directions being opposite. The proximal ends of the first section and the second section (i.e., the connection point between the two) are fixed to the partition 304, and the distal ends of the first section and the second section respectively form two second hanging nodes 301. In this way, the rotating disk 302 can be rotated under the action of an external force. Regardless of whether the rotating disk 302 rotates in the forward or reverse direction, one of the first section and the second section is in a continuously tightened state, while the other is in a continuously released state. Therefore, the hanging length of the two second hanging nodes 301 can be changed by rotating the rotating disk 302, thereby changing the angle of the steel column at the hanging point. In this embodiment, since a driving member is provided in the cavity 101 of the bearing seat 1 to drive the slider 202, another driving member (not shown) is also required to be provided on the bearing seat 1 to drive the rotating disk 302 to rotate. The two driving members described above are independently driven so that the two hoisting structures can be driven independently. Furthermore, the two driving members can be arranged on the supporting base 1, one on the left and one on the right, or one in front and one behind, so that the force on the supporting base 1 is balanced.

[0063] Preferably, the partition 304 is provided with a through hole for connecting the two winding bins, and the connection point of the two connecting sections is passed through and fixed to the through hole. In this embodiment, the connection point of the two connecting sections is fixed to the partition 304, so that during the rotation of the rotating disk 302, only the end of the second sling 303 changes in length, thereby adjusting the lifting length of the second lifting node 301. Of course, the connection point mentioned above can be the middle part of the second sling 303, which passes through the through hole and is fixed to the partition 304 using the through hole, so that the middle part of the second sling 303 can be relatively stationary with the rotating disk 302, while its end part moves relatively.

[0064] like Figure 1 、 Figure 7As shown, in one embodiment, a hinge point is formed at the connection between the sleeve 401 and the first support rod 402, and at the connection between the first support rod 402 and the second support rod 403. Specifically, the angle of the steel column is fine-tuned by utilizing the telescopic structure 404 of the support assembly 4; in this embodiment, a hinge point is formed between the sleeve 401 and the first support rod 402, and between the first support rod 402 and the second support rod 403, so that the two are rotatably connected. When adjusting the elongation of the telescopic structure 404, the corresponding hinge point can be used to rotate the corresponding support rod around the hinge point to change the length of the support rod. The telescopic structure 404 is a plurality of turnbuckles.

[0065] This embodiment also provides a construction method based on the above-mentioned installation device, comprising the following steps:

[0066] Install the first lifting node 201 and the second lifting node 301 along the two diagonal lines on the upper surface of the box-shaped steel column;

[0067] Hoisting the box-shaped steel column to a predetermined position of the foundation, and synchronously adjusting the hoisting lengths of the two first hoisting nodes 201; and / or synchronously adjusting the hoisting lengths of the two second hoisting nodes 301 to control the initial verticality of the box-shaped steel column and to allow the box-shaped steel column to hover until it slightly touches the bottom;

[0068] The hoop 401 is installed along the outer surface of the box-shaped steel column, and the lengths of the first support rod 402 and the second support rod 403 are adjusted by the corresponding telescopic structure 404 to match the initial verticality;

[0069] Fix the first support rod 402 and release the lifting assembly;

[0070] Measure the position and verticality of the box-shaped steel column, and adjust the corresponding telescopic structure 404 according to the measurement results to complete the final verticality adjustment of the box-shaped steel column;

[0071] After the box-shaped steel column is cast, the support assembly 4 is removed.

[0072] In this embodiment, before or during the stage when the steel column hovers and touches the bottom, the inclination angle of the steel column in two vertical directions can be quickly controlled by adjusting the two sets of diagonal lifting nodes, thereby achieving coarse adjustment of the initial verticality; the support rod of the support assembly 4 directly matches the initial verticality of the steel column during installation, and the coarse positioning can be transferred to the support assembly 4 without correction, and then the support assembly 4 is used for fine adjustment to determine the final verticality of the steel column, eliminating the interference caused by the lifting assembly, and making the positioning accuracy higher; finally, there is no need to remove the support assembly 4 during the entire pouring process, so that the support assembly 4 can play a role of stable support, ensuring that the position deviation value and verticality deviation value of the steel column meet the construction requirements.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
