Description

Technical Field

[0001] The invention relates to the technical field of steel structure building construction, and in particular to an auxiliary positioning device and an auxiliary positioning method thereof. Background Art

[0002] In the era of rapid development of my country's construction industry, steel structure buildings have become an important part of the construction industry. Among them, the steel structure column base, as one of the important components for positioning and fixing the entire steel structure, needs to be constructed simultaneously with the civil structure. In the process of tying steel bars in the foundation structure, the anchor screws need to be pre-embedded in the columns or beams, and then concrete is poured to form a stable anchor screw.

[0003] However, due to the existence of processes such as steel bar binding and concrete pouring in civil engineering columns or beams, and often the steel structure has not yet entered the factory at this time, the work of pre-embedded anchor screws is completed by civil engineering work and cannot be completed by professional steel structure construction personnel. Therefore, there is always a situation where the anchor screws are misaligned during construction. For example, the gap between the two anchor screws is too large or too small, but the column base plate is processed and opened strictly according to the drawings. Therefore, when the column base plate is installed on site, the hole on the column base plate cannot be inserted into the buried screw. At this time, the column base plate needs to be expanded for a second time, and the size and position of the expanded hole are directly related to the construction quality of the embedded column foot.

[0004] Therefore, how to expand the hole as little as possible or complete it in one time under the condition of ensuring normal penetration is very important to improve on-site work efficiency and ensure the quality of hole expansion. The general process is to lift the column base plate multiple times and then mark the bottom of the column base plate to complete multiple hole expansions. The lifting equipment is needed, which increases the construction cost. When the weight of the column base plate is large, the lifting is difficult and there are great safety hazards when marking. Summary of the invention

[0005] The purpose of the present invention is to provide an auxiliary positioning device and an auxiliary positioning method thereof, which have the characteristics of high installation efficiency, high positioning accuracy, safety and reliability, and recyclability. At the same time, it also avoids the problem that due to the large pre-embedded deviation of the foundation screws in the early stage of civil engineering, the quality of the column base plate expansion hole is difficult to ensure when the lifting is used, the lifting is difficult, the efficiency is low, and there are safety hazards when marking.

[0006] In order to achieve the above-mentioned purpose, the present invention provides an auxiliary positioning device for positioning multiple bolt holes on a column base plate, the bolt holes corresponding one-to-one to multiple pre-embedded anchor screws, the anchor screw comprising a reference screw, the reference screw being located at the center of the multiple anchor screws, and characterized in that the auxiliary positioning device comprises a positioning component and a marking component, the positioning component comprising at least three positioning sleeves and at least three length-adjustable connecting pieces, the positioning sleeves comprising a reference positioning sleeve and at least two auxiliary positioning sleeves, the reference positioning sleeve being sleeved outside the reference screw, the auxiliary positioning sleeves being sleeved outside different anchor screws respectively, the multiple connecting pieces being used to respectively connect the reference positioning sleeves with different auxiliary positioning sleeves, and the multiple connecting pieces are on the same horizontal plane, and the marking component is used to mark the relative position information between the reference positioning sleeve and the auxiliary positioning sleeve on the column base plate.

[0028] Please refer to Figure 1-Figure 2 , Figure 1 A schematic diagram of the structure of an auxiliary positioning device provided in an embodiment of the present invention, Figure 2 A schematic diagram of marking a column base plate provided in an embodiment of the present invention, the present embodiment provides an auxiliary positioning device for positioning a plurality of bolt holes 11 on a column base plate 10, the bolt holes 11 corresponding one to one with a plurality of pre-buried anchor screws 20, the anchor screw 20 comprising a reference screw 21, the reference screw 21 being located at the center of the plurality of anchor screws 20, the auxiliary positioning device comprising a positioning component and a marking component, the positioning component comprising at least three positioning sleeves 30 and at least three length-adjustable connectors 40, the positioning sleeves 30 comprising a reference positioning sleeve 31 and at least two auxiliary positioning sleeves 32, the reference positioning sleeve 31 being sleeved outside the reference screw 21, the auxiliary positioning sleeves 32 being sleeved outside different anchor screws 20, the plurality of connectors 40 being used to respectively connect the reference positioning sleeve 31 with different auxiliary positioning sleeves 32, and the plurality of connectors 40 being on the same horizontal plane, the marking component being used to mark the relative position information between the reference positioning sleeve 31 and the auxiliary positioning sleeve 32 on the column base plate 10.

[0029] The positioning component can measure the distance between the reference screw 21 and other anchor screws 20, and then the marking component can mark the bolt holes 11 on the column base plate 10 according to the measurement information. The positions of all the bolt holes 11 can be marked by repeating this process multiple times, so that the bolt holes 11 can be enlarged on the column base plate 10 according to the marking information. The auxiliary positioning device provided in this embodiment has the characteristics of high installation efficiency, high positioning accuracy, safety and reliability, and recyclability. At the same time, it also avoids the problem that due to the large pre-embedded deviation of the anchor screws 20 in the early stage of civil engineering, the quality of the subsequent enlargement of the column base plate 10 by the method of lifting and marking is difficult to guarantee, the lifting is difficult, the efficiency is low, and there are safety hazards when marking.

[0030] Specifically, the plurality of anchor screws 20 are usually evenly distributed on the foundation, for example, forming a square, and include a reference screw 21 located at the center of the plurality of anchor screws 20. It should be understood that when the reference screw 21 is not provided at the center of the plurality of anchor screws 20, it can be considered that a rigid protruding structure is provided to serve as a reference point for subsequent positioning measurement. In this embodiment, there are 25 anchor screws 20, of which 24 anchor screws 20 form a square, and a reference screw 21 is provided at the center of the square.

[0031] In this embodiment, the positioning assembly includes a reference positioning sleeve 31, two auxiliary positioning sleeves 32 and three length-adjustable connectors 40. The reference positioning sleeve 31 and the two auxiliary positioning sleeves 32 form a triangle, and the stability principle of the triangle is used to improve the measurement accuracy. Of course, the number of the auxiliary positioning sleeves 32 can also be greater than three, and this application does not impose any restrictions on this.

[0032] In this embodiment, the positioning sleeve 30 is a rigid structure, that is, the positioning sleeve 30 will not be deformed, for example, a steel pipe can be used, and when measuring, the positioning sleeve 30 can be directly inserted into the corresponding anchor screw 20. Considering the accuracy of measurement, each positioning sleeve 30 is on the same horizontal plane.

[0033] Preferably, the positioning sleeve 30 is concentrically arranged with the anchor screw 20. Since the positioning sleeve 30 is used to mark the column base plate 10 later, such as marking, the positioning sleeve 30 is concentrically arranged with the anchor screw 20 to improve the accuracy of the marking, thereby improving the quality of the hole expansion and preventing the hole expansion from being too large, which affects the connection strength between the anchor screw 20 and the column base plate 10. Of course, during actual construction, the positioning sleeve 30 is usually designed according to the diameter of the anchor screw 20, and the inner diameter of the positioning sleeve 30 only needs to be slightly larger than the diameter of the anchor screw 20. With such a design, even if there is a certain deviation between the center of the positioning sleeve 30 and the center of the anchor screw 20, it will not have much impact on the measurement result.

[0034] Please refer to Figure 3 , Figure 3 This is a partial enlarged view of the positioning assembly provided in an embodiment of the present invention, wherein the connector 40 includes a central sleeve 41 and two threaded screws 42 respectively located at both ends of the central sleeve 41, wherein the central sleeve 41 is a hollow structure and is provided with an internal thread, and the threaded screw 42 has an external thread to be screwed into the central sleeve 41. In other words, the threaded screw 42 is threadedly connected to the central sleeve 41, and the screwing length of the threaded screw 42 in the central sleeve 41 can be adjusted by rotating the threaded screw 42, thereby adjusting the length of the entire connector 40.

[0035] In this embodiment, the external threads on the two threaded screws 42 have opposite rotation directions.

[0036] Preferably, the connecting member 40 is rigidly connected to the positioning sleeve 30 to ensure measurement accuracy. In this embodiment, the end of the threaded screw 42 away from the center sleeve 41 is threadedly connected to the positioning sleeve 30. Specifically, the end of the threaded screw 42 away from the center sleeve 41 and the outer wall of the positioning sleeve 30 are correspondingly provided with connecting holes, and the auxiliary positioning device also includes a plurality of bolts 50 and a plurality of fastening nuts 51. The bolts 50 pass through the threaded screw 42 and the corresponding connecting holes on the positioning sleeve 30 and are locked by the fastening nuts 51.

[0037] Preferably, a torsion nut 60 is disposed on the outer sleeve of the central sleeve 41, and the length of the threaded screw 42 screwed into the central sleeve 41 can be adjusted by rotating the torsion nut 60. The torsion nut 60 is similar to the design of a handle, so that construction workers can quickly and conveniently rotate the central sleeve 41 to adjust the length of the connecting member 40.

[0038] In this embodiment, the marking component includes a marking pen, which is used to draw lines on the column base plate 10 according to the relative position information between the reference positioning sleeve 31 and the auxiliary positioning sleeve 32, so as to facilitate the subsequent expansion of the bolt hole 11 on the column base plate 10.

[0039] Based on the auxiliary positioning device, combined with Figure 1-Figure 3 The present invention also provides an auxiliary positioning method, comprising the following steps:

[0040] S1, insert the reference positioning sleeve 31 into the reference screw 21, and insert the auxiliary positioning sleeve 32 into the remaining anchor screws 20;

[0041] S2, installing a connecting piece 40 between the reference positioning sleeve 31 and the auxiliary positioning sleeve 32, and adjusting the length of each connecting piece 40 so that the multiple connecting pieces 40 are on the same horizontal plane;

[0042] S3, take out the entire auxiliary positioning device and place it on the column base plate 10, align the reference positioning sleeve 31 with the center of the column base plate 10, and mark the position of each auxiliary positioning sleeve 32 on the column base plate 10 in sequence.

[0043] First, execute step S1, insert the reference positioning sleeve 31 into the reference screw 21, and insert the auxiliary positioning sleeve 32 into the remaining anchor screws 20. Specifically, according to the distribution of the anchor screws 20 on site, orderly staged measurements are performed, for example, there are a total of 25 anchor screws 20, of which 24 anchor screws form a square, and an anchor screw 20 is arranged at the center of the square, that is, the reference screw 21 in the present application, and 6 anchor screws 20 are distributed on each side. For example, the reference screw 21 is named No. 0 bolt, and the remaining 24 anchor screws 20 are named No. 1 bolt, No. 2 bolt, No. 3 bolt... No. 24 bolt in clockwise order, and then the relative positions of No. 1 bolt and No. 2 bolt can be measured in sequence, and the reference positioning sleeve 31 is inserted into the No. 0 bolt, and the two auxiliary positioning sleeves 32 are respectively inserted into the No. 1 bolt and the No. 2 bolt.

[0044] Then, step S2 is performed to install the connector 40 between the reference positioning sleeve 31 and the auxiliary positioning sleeve 32, and adjust the length of each connector 40 so that the multiple connectors 40 are on the same horizontal plane. After the length of each connector 40 is adjusted, the relative position between the reference positioning sleeve 31 and the auxiliary positioning sleeve 32 is fixed.

[0045] Finally, step S3 is performed, the entire auxiliary positioning device is taken out and placed on the column base plate 10, the reference positioning sleeve 31 is aligned with the center of the column base plate 10, and the position of each auxiliary positioning sleeve 32 on the column base plate 10 is marked in sequence. Since the relative position between the reference positioning sleeve 31 and the auxiliary positioning sleeve 32 is fixed, the entire auxiliary positioning device is placed on the column base plate 10, and marking (marking) can be performed by using a marking component (marking pen).

[0046] By repeating the above steps S1 to S3 , the position information of all the bolt holes 11 on the column base plate 10 can be located.

[0047] In summary, the embodiments of the present invention provide an auxiliary positioning device and a positioning method thereof, which are used to position multiple bolt holes on a column base plate. The spacing between the reference screw and other anchor screws can be measured by the positioning component, and then the bolt holes can be marked on the column base plate according to the measurement information by the marking component. The positions of all bolt holes can be marked by repeating the process multiple times, so as to facilitate the subsequent expansion of the bolt holes according to the marking information. The auxiliary positioning device and the positioning method provided by the present invention have the characteristics of high installation efficiency, high positioning accuracy, safety and reliability, and recyclability. At the same time, they also avoid the problem that the quality of the column base plate expansion by the subsequent lifting and marking method is difficult to guarantee due to the large pre-embedded deviation of the anchor screws in the early stage of civil engineering, the lifting is difficult, the efficiency is low, and there are safety hazards when marking.
