Description

Technical Field

[0001] This utility model belongs to the field of building installation technology, and in particular relates to a pre-embedded anchor bolt installation and positioning device for the first section of steel column. Background Technology

[0002] An installation and positioning device for pre-embedded anchor bolts in the first section of a steel column is a specialized piece of equipment used to ensure the accurate positioning of pre-embedded anchor bolts during the installation of the first section of the steel column. It typically consists of a positioning frame, an adjustment component, and a fixing component. The positioning frame initially defines the spatial position of the anchor bolt, the adjustment component allows for fine-tuning of the anchor bolt in the horizontal and vertical directions, and the fixing component securely connects the anchor bolt to the foundation reinforcement or formwork. This ensures that the anchor bolt position remains unchanged during construction processes such as concrete pouring, guaranteeing the accuracy and stability of subsequent steel column installation and improving the construction quality and efficiency of steel structure engineering.

[0003] In the construction of steel structures, there are difficulties in connecting the first section of steel column with the pre-embedded anchor bolts. Due to the large number of anchor bolts and the need to pre-embed them according to the drawings, the positioning accuracy is difficult to control due to the influence of site conditions and measurement errors. This makes it difficult for the anchor bolts to be accurately inserted into the anchor bolt holes on the steel column. If forced installation is carried out, it is easy to cause the first section of steel column to deviate and cause errors in the upper steel columns, affecting the verticality and stability of the steel structure. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for pre-embedded anchor bolts in the first section of a steel column. By setting up a positioning part, the problem of connecting the first section of the steel column with the pre-embedded anchor bolts is solved. Because there are many anchor bolts and they need to be pre-embedded according to the drawings, the positioning accuracy is difficult to control due to the influence of site conditions and measurement errors. This makes it difficult for the anchor bolts to be accurately inserted into the anchor bolt holes on the steel column. If forced to install, it is easy to cause the first section of the steel column to deviate and cause errors in the upper steel columns, affecting the verticality and stability of the steel structure.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a pre-embedded anchor bolt installation and positioning device for a first-section steel column, comprising a base plate, and further comprising: a positioning part, which is installed on the base plate and is used to precisely connect the steel column on the base plate to the pre-embedded anchor bolt; and an auxiliary part, which is installed on the base plate and is used to assist in positioning when welding the steel column to the base plate; wherein, when welding the steel column to the base plate, the auxiliary part can be used to assist in welding, and after the steel column to the base plate is welded, the positioning part can be used to accurately install the steel column.

[0007] Furthermore, the positioning part includes a connecting component disposed on the base plate for facilitating the connection between the steel column and the pre-embedded anchor bolt; and a positioning component disposed on the base plate for fixing the base plate; wherein, when connecting the connecting component and the pre-embedded anchor bolt, the positioning component enables a precise connection.

[0008] Furthermore, the auxiliary part includes two clamping assemblies mounted on the base plate for positioning when connecting the steel column to the base plate; and two adjusting assemblies mounted on the clamping assemblies for flexible adjustment according to the installation of the steel column. When welding the steel column to the base plate, the clamping assemblies and adjusting assemblies can be used to limit the position of both, which not only facilitates the welding operation but also reduces errors caused by manual assistance.

[0009] Furthermore, the connecting assembly includes a steel column set on the top of the base plate, with several column base stiffening ribs fixedly connected to the outer wall of the steel column, and a shear key fixedly connected to the bottom of the base plate; wherein, a total of eight column base stiffening ribs are provided and evenly distributed around the steel column, so as to make the column base of the steel column bear the force evenly.

[0010] Furthermore, the positioning component includes several anchor bolt holes formed on the top of the base plate. Each of the anchor bolt holes has a column anchor bolt slidably connected to its inner wall. Each of the column anchor bolts has a first adjusting nut threadedly connected to its outer wall. The tops of each of the first adjusting nuts are in contact with the base plate. Each of the column anchor bolts has two second adjusting nuts threadedly connected to its outer wall. The presence of two second adjusting nuts on the outer wall of the column anchor bolt, along with the double nuts, secures the base plate to the column anchor bolt, thus improving the connection's strength.

[0011] Furthermore, the clamping assembly includes a support foot fixedly connected to the bottom of the base plate, a sliding groove is provided on the top of the base plate, two rectangular blocks are fixedly connected to the bottom of the base plate, a screw is rotatably connected to the two rectangular blocks, a manual knob is sleeved on the outer wall of the screw, a clamping plate is threadedly connected to the outer wall of the screw, and a balancing component is provided on the rectangular block; wherein, the front end of the screw extends to the outside of the corresponding rectangular block and is rotatably connected to the corresponding rectangular block.

[0012] Furthermore, the adjustment assembly includes a second slide groove formed on the clamping plate, the inner wall of the second slide groove being slidably connected to two bidirectional screws, the right outer wall of the bidirectional screws being threadedly connected to a second manual knob, the outer wall of the bidirectional screws being threadedly connected to two adjustment plates, both of the adjustment plates being in contact with the corresponding column foot stiffening ribs; wherein, the right end of the bidirectional screws extends out of the clamping plate and is rotatably connected to the clamping plate.

[0013] Furthermore, the balancing component includes a balance bar fixedly connected to one side of the two rectangular blocks that are close to each other; wherein the balance bar passes through the clamping plate and is slidably connected to the clamping plate, and the balance bar enables the clamping plate to be more stable during sliding.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a positioning section, during the installation of steel columns, precise positioning holes must first be drilled on the base plate according to the position of the column base anchor bolts. After drilling, the steel column can be hoisted. During hoisting, the anchor bolt holes on the bottom plate of the steel column must be aligned and the anchor bolts passed through, ensuring that the base plate and the first adjusting nut on the anchor bolt hole are tightly fitted. Then, two second adjusting nuts are used to reinforce the steel column. After the steel column completes the above installation steps, the concrete pouring stage can begin. This process uses micro-expansion fine aggregate concrete, poured from the bottom of the steel column and one side of the shear groove, and simultaneously vibrated with a construction vibrator to ensure the concrete is dense. In addition, the stiffening ribs at the column base must be completely wrapped and protected with concrete. This setting effectively solves the problem of difficult positioning of the pre-embedded anchor bolts and the steel column. By utilizing the combination of the base plate holes and adjusting nuts, precise fine-tuning of the steel column installation position is achieved, significantly reducing installation difficulties caused by errors.

[0016] 2. By setting up an auxiliary part, during the installation of the steel column and the base plate, the steel column and its multiple column base stiffening ribs are first placed on the base plate. Then, the manual knob one on the screw is turned. The screw drives the clamping plate through the balance bar. According to the scale on the base plate, the steel column and its column base stiffening ribs are centered and positioned. If the positioning needs to be adjusted according to the actual size of the column base stiffening ribs, the manual knob two on the double-ended screw is turned. The double-ended screw will drive the two adjusting plates to move closer to each other, thereby effectively limiting the column base stiffening ribs and preventing displacement during the positioning process. After all adjustments are in place, the steel column and the base plate can be welded and fixed. This method not only simplifies the welding operation process but also reduces the errors caused by manual assistance, effectively improving installation accuracy and construction efficiency.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8As shown, this utility model is a positioning device for pre-embedded anchor bolts in a first-section steel column, including a base plate 1, and further including: a positioning part 2, which is installed on the base plate 1 and is used to accurately connect the steel column on the base plate 1 to the pre-embedded anchor bolt; and an auxiliary part 3, which is installed on the base plate 1 and is used to assist in positioning when welding the steel column to the base plate 1; wherein, when welding the steel column to the base plate 1, the auxiliary part 3 can be used to assist in welding, and after the steel column to the base plate 1 is welded, the positioning part 2 can be used to accurately install the steel column.

[0031] The positioning part 2 includes a connecting component 21, which is mounted on the base plate 1 to facilitate the connection between the steel column and the pre-embedded anchor bolts; and a positioning component 22, which is mounted on the base plate 1 to fix the base plate 1 in place. When connecting the connecting component 21 and the pre-embedded anchor bolts, the positioning component 22 enables a precise connection. The connecting component 21 includes a steel column 211 mounted on the top of the base plate 1, with several column base stiffening ribs 212 fixedly connected to the outer wall of the steel column 211, and a shear key 213 fixedly connected to the bottom of the base plate 1. Eight column base stiffening ribs 212 are provided in total and evenly distributed around the steel column 211. The positioning component 22, which ensures uniform force distribution on the column base of the steel column 211, includes several anchor bolt holes 221 on the top of the base plate 1. Column base anchor bolts 222 are slidably connected to the inner walls of each anchor bolt hole 221, and first adjusting nuts 223 are threadedly connected to the outer walls of each anchor bolt 222. The tops of each first adjusting nut 223 are in contact with the base plate 1, and two second adjusting nuts 224 are threadedly connected to the outer walls of each anchor bolt 222. The two second adjusting nuts 224 on the outer walls of the anchor bolts 222, used to fix the base plate 1 on the anchor bolts 222, improve the connection's stability.

[0032] By setting the positioning part 2, during the installation of the steel column, it is necessary to first make precise positioning holes on the base plate 1 according to the position of the column base anchor bolt 222. After the holes are made, the steel column 211 can be hoisted. During hoisting, the anchor bolt holes 221 on the bottom plate 1 of the steel column 211 should be aligned and passed through the column base anchor bolt 222, so that the base plate 1 and the first adjusting nut 223 on the anchor bolt hole 221 are tightly fitted. Then, two second adjusting nuts 224 are used to reinforce the steel column 211. When the steel column 211 is completed, the installation is completed. After the installation steps are described, the concrete pouring process can begin. This process uses micro-expansion fine aggregate concrete, which is poured from the bottom of the steel column and one side of the shear groove. Simultaneously, a construction vibrator is used to compact the concrete to ensure that it is dense. In addition, the stiffening ribs at the column base must be completely wrapped and protected with concrete. This feature effectively solves the problem of difficult positioning of the pre-embedded anchor bolts and the steel column. By using the opening in the base plate and the adjustment nut, the precise fine-tuning of the steel column installation position is achieved, significantly reducing installation difficulties caused by errors.

[0033] The auxiliary part 3 includes two clamping components 31, which are mounted on the base plate 1 and used for positioning when connecting the steel column to the base plate 1; and two adjusting components 32, which are mounted on the clamping components 31 and used for flexible adjustment according to the installation of the steel column. When welding the steel column to the base plate 1, the clamping components 31 and adjusting components 32 can be used to limit the position of the two, which not only facilitates the welding operation, but also reduces the error caused by manual assistance.

[0034] The clamping assembly 31 includes a foot 311 fixedly connected to the bottom of the base plate 1. A groove 312 is provided on the top of the base plate 1. Two rectangular blocks 313 are fixedly connected to the bottom of the base plate 1. A screw 314 is rotatably connected to the two rectangular blocks 313. A manual knob 315 is sleeved on the outer wall of the screw 314. A clamping plate 316 is threadedly connected to the outer wall of the screw 314. A balancing component is provided on the rectangular block 313. The front end of the screw 314 extends to the outside of the corresponding rectangular block 313 and is rotatably connected to the corresponding rectangular block 313.

[0035] The adjustment assembly 32 includes a second slide groove 321 formed on the clamping plate 316. Two bidirectional screws 322 are slidably connected to the inner wall of the slide groove 321. A manual knob 323 is threadedly connected to the outer right side of the bidirectional screws 322. Two adjustment plates 324 are threadedly connected to the outer wall of the bidirectional screws 322. Both adjustment plates 324 are in contact with the corresponding column foot stiffening ribs 212. The right end of the bidirectional screws 322 extends to the outside of the clamping plate 316 and is rotatably connected to the clamping plate 316. The balancing component includes a balance rod 317 fixedly connected to one side of the two rectangular blocks 313 that are close to each other. The balance rod 317 passes through the clamping plate 316 and is slidably connected to the clamping plate 316.

[0036] The balance bar 317 enhances the stability of the clamping plate 316 during sliding. By providing the auxiliary part 3, during the installation of the steel column 211 and the base plate 1, the steel column 211 and its multiple stiffening ribs 212 are first placed on the base plate 1. Then, the manual knob 315 on the screw 314 is rotated. The screw 314, through the balance bar 317, drives the clamping plate 316 to center the steel column 211 and its stiffening ribs 212 according to the scale on the base plate 1. If further adjustments are needed... Adjust the positioning according to the actual size of the stiffening rib 212 at the column base. Then, rotate the manual knob 323 on the double-acting screw 322. The double-acting screw 322 will drive the two adjusting plates 324 to move closer to each other, thereby effectively limiting the stiffening rib 212 at the column base and preventing displacement during the positioning process. After all adjustments are in place, the steel column and the base plate can be welded and fixed. This method not only simplifies the welding operation process, but also reduces errors caused by manual assistance, effectively improving installation accuracy and construction efficiency.

[0037] A specific application of this embodiment is as follows: When installing steel columns, it is necessary to first accurately position and drill holes on the base plate 1 according to the position of the column foot anchor bolts 222. After drilling, the steel column 211 can be hoisted. During hoisting, the anchor bolt holes 221 on the bottom plate 1 of the steel column 211 should be aligned and passed through the column foot anchor bolts 222, so that the base plate 1 and the first adjusting nut 223 on the anchor bolt hole 221 are tightly fitted. Then, two second adjusting nuts 224 are used to reinforce the steel column 211. After the steel column 211 completes the above installation steps, the concrete pouring stage can begin. This process uses micro-expansion fine stone concrete, which is poured from the bottom of the steel column and one side of the shear groove, and a construction vibrator is used simultaneously to ensure that the concrete is poured densely.

[0038] The stiffening ribs at the column base need to be completely encased in concrete for protection. This design effectively solves the problem of difficult positioning of the pre-embedded anchor bolts and the steel column. By utilizing the openings in the base plate and the adjustment nuts, precise fine-tuning of the steel column installation position is achieved, significantly reducing installation difficulties caused by errors.

[0039] During the installation of the steel column 211 and the base plate 1, the steel column 211 and its multiple stiffening ribs 212 are first placed on the base plate 1. Then, the manual knob 315 on the screw 314 is turned. The screw 314 drives the clamping plate 316 through the balance bar 317. According to the scale on the base plate 1, the steel column 211 and its stiffening ribs 212 are centered. If the positioning needs to be adjusted according to the actual size of the stiffening ribs 212, the manual knob 323 on the double-acting screw 322 is turned. The double-acting screw 322 will drive the two adjusting plates 324 to move closer to each other, thereby effectively limiting the stiffening ribs 212 and preventing displacement during the positioning process. After all adjustments are in place, the steel column and the base plate can be welded and fixed. This method not only simplifies the welding operation process but also reduces the errors caused by manual assistance, effectively improving the installation accuracy and construction efficiency.
