Description

Technical Field

[0001] The utility model relates to the field of steel frame building construction, and particularly relates to a positioning assistant for steel structure column foot bolts. Background Art

[0002] In steel frame structure buildings, the positioning of column foot embedded parts is crucial. First of all, the size and position of the embedded parts must be precisely matched with the structural design to ensure the accuracy and stability of subsequent column installation. As a key positioning and fixing component in steel frame buildings, the construction of steel structure column feet must be closely coordinated with the civil engineering structure. During the construction process, it is necessary to ensure the accurate installation of the embedded parts in the concrete foundation, which usually requires precise reserved holes and positioning equipment to ensure the accuracy of the position and size.

[0003] In steel frame structure buildings, the positioning of column foot embedded parts generally has high installation accuracy requirements, resulting in great construction difficulty during on-site construction and the problem that the subsequent steel columns cannot be installed due to the deviation of the column foot embedded part positioning.

[0004] Therefore, providing a positioning assistant for steel structure column foot bolts has become a problem worthy of research. Content of the Utility Model

[0005] In order to solve the deficiencies existing in the above-mentioned prior art, the purpose of the utility model is to quickly measure the size of cylindrical parts, and the operation is simpler and more convenient.

[0006] The purpose of the utility model is achieved as follows:

[0007] A positioning assistant for steel structure column foot bolts provided by the utility model includes a positioning surface layer. The number of the positioning surface layers is not less than two, and adjacent two layers of the positioning surface layers are rotationally connected through the rotating connecting rods. Each layer of the positioning surface layer contains four positioning rings, and the positioning rings are located at the four corners of a rectangle. A length-adjustable length-adjusting rod is connected between adjacent two positioning rings, and the length-adjusting rods on adjacent two layers of the positioning surface layers are of different lengths.

[0008] In some embodiments, the number of the positioning surface layers is two.

[0009] In some embodiments, the rotating connecting rods are rotationally connected between the corresponding positioning rings on the upper and lower two layers of the positioning surface layers.

[0010] In some embodiments, the length-adjusting rod includes a plurality of sliding sleeves sleeved together. A locking bolt for locking the inner sliding sleeve is threadedly connected to the outer sliding sleeve, and the movable ends of the multiple sliding sleeves are respectively connected to the positioning rings on both sides.

[0024] The present utility model will be further described below with reference to the drawings and embodiments. Embodiment 1

[0025] See Figures 1-3 As shown, a positioning assistant for steel structure column foot bolts provided by the present utility model includes a positioning surface layer 1. The number of the positioning surface layers 1 is not less than two. Adjacent two layers of the positioning surface layers 1 are rotationally connected by a rotating link 3. Each layer of the positioning surface layer 1 contains four positioning rings 4. The radius of the 4 is 10 mm. The positioning rings 4 are located at the four corners of a rectangle. Preferably, the positioning rings 4 correspond to the four corners of a square. A length-adjustable length-adjusting rod 2 is connected between two adjacent positioning rings 4. The lengths of the length-adjusting rods 2 on adjacent two layers of the positioning surface layers 1 are different. By adjusting the length of the length-adjusting rod 2, after locking the length-adjusting rod 2 on any layer, pushing another layer of the positioning surface layer 1 can adjust the length of the length-adjusting rod 2 on the other layer of the positioning surface layer 1;

[0026] The number of the positioning surface layers 1 is two. The two layers of the positioning surface layers 1 are arranged up and down. When the device is in use, lock the length-adjusting rod 2 on the upper positioning surface layer 1, and push the upper positioning surface layer 1 to move the upper positioning surface layer 1 towards the lower positioning surface layer 1. At this time, since the upper positioning surface layer 1 is an overall fixed structure, the rotating link 3 can be used to push the positioning rings 4 on the lower positioning surface layer 1 to move away from each other, so that the distance between the positioning rings 4 on the lower positioning surface layer 1 can be adjusted. After the adjustment is completed, lock the length-adjusting rod 2 on the lower positioning surface layer 1. When in use, the positioning rings 4 on the lower positioning surface layer 1 can be used to assist in positioning the position of the steel structure column foot bolts;

[0027] In addition, the length of the length-adjusting rod 2 on the lower positioning surface layer 1 can be locked, and the length-adjusting rod 2 on the upper positioning surface layer 1 is in a length-adjustable state. By pulling up or pushing down the upper positioning surface layer 1, and using the rotating link 3 to assist the movement of the upper positioning surface layer 1, the length of the length-adjusting rod 2 on the upper positioning surface layer 1 can be adjusted, and the distance between the positioning rings 4 on the upper positioning surface layer 1 can be adjusted. After the adjustment, lock the length-adjusting rod 2 on the upper positioning surface layer 1. When in use, reverse the device, place the upper positioning surface layer 1 on the ground, and use the positioning rings 4 placed on the ground to assist in positioning the position of the steel structure column foot bolts;

[0028] In the use of this device, since the lengths of the length-adjusting rods 2 on the upper and lower positioning surface layers 1 are different, the overall device has a larger adjustment range. The rotating link 3 on the upper or lower positioning surface layer 1 can be used to position the steel structure column foot bolts according to the actual size. The positioning effect is good, the use is more flexible, and the positions of the steel structure column foot bolts of two models can also be positioned simultaneously through the positioning rings 4 on the upper and lower positioning surface layers 1. The use is more flexible and the use effect is good.

[0029] When the number of positioning surface layers 1 is greater than the number of length-adjusting rods 2, the positioning surface layer 1 to be used is adjusted to the outermost layer of the device by rotating the rotating connecting rod 3 according to the usage requirements. Since the length of the length-adjusting rod 2 can be adjusted, under the rotation of the rotating connecting rod 3, the number of layers of the shorter length-adjusting rods 2 can be adjusted to the inner side, so as to facilitate the adjustment and use of the outer positioning surface layer 1. When the positioning surface layer 1 is in a multi-layer state, the same device has a larger adjustment range. During use, there is no need to carry multiple models, making it more convenient to use.

[0030] Extend this positioning aid to the corresponding size according to the positioning of the on-site foundation embedded parts, and then insert the embedded parts into the rigid positioning ring to ensure the accurate positioning of the embedded parts. Finally, after the embedded parts are welded, the positioning aid can be taken out from above and can be reused later.

[0031] Embodiment 2 is different from Embodiment 1 in that

[0032] The rotating connecting rod 3 is rotatably connected between the corresponding positioning rings 4 on the upper and lower layers of the positioning surface layer 1. There are four rotating connecting rods 3, and they respectively correspond to the positioning rings 4 on the upper and lower layers of the positioning surface layer 1, realizing the rotational connection of the corresponding positioning rings 4 on the upper and lower layers of the positioning surface layer 1. After the rotating connecting rod 3 rotates, the distance between the positioning rings 4 on the upper layer or the lower layer can be adjusted, and the adjustment is more convenient and fast, with good use effect. And the positions of the column foot bolts of two types of steel structures are respectively positioned through the positioning rings 4 on the upper and lower positioning surface layers 1, and the adjustment range is wider.

[0033] In the structure of the length-adjusting rod 2, the length-adjusting rod 2 includes a plurality of sliding sleeves 201 arranged in a sleeved manner. The sliding sleeve 201 has a tubular structure. Preferably, the sliding sleeve 201 has a square tube structure. When the length-adjusting rods 2 are far away from each other, the mutual sliding of the sliding sleeves 201 has a better adjustment effect. Further, a locking bolt 203 for locking the inner sliding sleeve 201 is threadedly connected to the outer sliding sleeve 201. The movable ends of the multiple sliding sleeves 201 are respectively connected to the positioning rings 4 on both sides, and the number of sliding sleeves 201 is greater than or equal to 2. By extending or retracting the inner sliding sleeve 201, the overall length of the length-adjusting rod 2 can be adjusted to an appropriate distance. After the adjustment is completed, the locking bolt 203 is screwed to lock and fix the inner sliding sleeve 201, and the locking effect is good.

[0034] Further, a scale marking 202 is provided on the inner sliding sleeve 201. The scale marking 202 is used to facilitate the determination of the distance between two adjacent positioning rings 4, so as to ensure the accuracy of the position of the steel structure column foot. Further, a spirit level is provided on the sliding sleeve 201, and the spirit level can be used to assist the sliding sleeve 201 to be placed horizontally and stably.

[0035] Example 3, the difference from Example 1 lies in that

[0036] The positioning ring 4 is integrally in a ring structure, and its inner wall ring surface is used for auxiliary scribing and positioning operations. Moreover, the inner wall of the positioning ring 4 is inclined, and the low end of the inclined surface is set away from the rotating link 3. With this setting, when the device is placed at the drilling position, it is convenient to make marks and improve the accuracy of scribing.

[0037] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
