Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a construction positioning device for anchor bolts Background Art

[0002] During the construction of a steel structure workshop, anchor bolts are connecting components that connect the main structure and the foundation. Therefore, the position control of anchor bolts is the key to position control in foundation construction. Currently, when installing anchor bolts, the anchor bolts are positioned and welded through steel plates. During the welding process, the perpendicularity of the anchor bolts cannot be guaranteed, and it is easy to exceed the specified range of the allowable deviation of the center offset of column foot anchor bolts of 5 mm and the allowable positive deviation of the thread length and the exposed length of the anchor bolts of 30 mm in the Code for Acceptance of Construction Quality of Steel Structure Engineering. After exceeding the range, it seriously affects the subsequent construction. At the same time, the steel plates will be poured into the concrete together with the anchor bolts and cannot be reused, resulting in a large waste of cost

[0003] The document with the authorization announcement number of CN220954743U discloses an installation positioning die for anchor bolts, which includes a positioning box body. The positioning box body is composed of an upper positioning plate, a lower positioning plate, and inner and outer ring plates. A plurality of positioning holes are oppositely opened on the upper positioning plate and the lower positioning plate. An anchor bolt is commonly inserted through two opposite positioning holes. Fixing nuts are screwed on both the upper and lower sides of the positioning box body on the anchor bolt

[0004] The working principle of this device is as follows: First, a fixing nut is screwed on the anchor bolt, then the top end of the anchor bolt is sequentially inserted upward into two opposite positioning holes, and a fixing nut is screwed on the top end of the anchor bolt. The two positioning nuts fix the anchor bolt on the positioning box body. At the same time, the two opposite positioning holes can ensure the perpendicularity of the anchor bolt. After the subsequent construction is completed, the die can be disassembled and used for turnover

[0005] However, this device still has the following problems: The position where the anchor bolt is installed needs to be leveled on the ground first, and then the positioning die is installed. The leveling process generally requires manual repeated measurement and pouring of concrete to form a leveling surface, with poor accuracy. When installing the anchor bolt, the anchor bolt needs to be adjusted multiple times to eliminate the errors generated during leveling, which takes a long time Summary of the Utility Model

[0006] Aiming at the above problems, the purpose of the utility model is to provide a construction positioning device for anchor bolts. Through the setting of the leveling structure, the device can pour a leveling layer at the installation position of the anchor bolts by itself, and the leveling layer is distributed in a dot pattern, corresponding to the installation positions of the anchor bolts one by one. This not only avoids the cumbersome steps of repeated leveling, but also reduces the pouring volume and pouring waiting time. At the same time, the structure can be disassembled and reused after work installation, with the advantages of high work efficiency, strong practicability, and good economy

[0034] This embodiment provides a construction positioning device for anchor bolts, which includes a positioning box body 1 and a leveling structure arranged at the lower end of the positioning box body 1.

[0035] In this embodiment, the positioning box body 1 includes an upper positioning plate 12 and a lower positioning plate 13. The upper positioning plate 12 and the lower positioning plate 13 are both provided with positioning holes 11, and the positioning holes on the upper positioning plate 12 and the lower positioning plate 13 correspond one by one for passing through the anchor bolts a. Preferably, the upper positioning plate 12 and the lower positioning plate 13 are the same, both are rectangular plates, and a rectangular hole is opened in the middle of the rectangular plate. The inner and outer sides of the two positioning plates are respectively connected by two ring plates to enhance the structural strength. It can be understood that when installing the anchor bolts a, at least two fixing nuts are screwed on the anchor bolts a, and the two fixing nuts are respectively located on the surfaces of the two positioning plates facing away from each other.

[0036] In this embodiment, the leveling structure includes a frame body 21, an opening 22 arranged on the frame body 21 and matching with the positioning hole 11, a connecting piece 23 arranged on the frame body 21 and detachably connected to the positioning box body 1, and a pouring mold 24 slidably connected to the frame body 21 and inserted into the opening 22.

[0037] Among them, the housing 21 has the same outer shape as the positioning plate. The connecting member 23 is vertically connected to the surface of the housing 21. The casting mold 24 is used to inject concrete or other existing filling materials to form a number of support blocks corresponding one by one to the installation positions of the anchor bolts a, and all the support blocks are on the same horizontal plane to ensure that the installation heights of all the anchor bolts a are the same.

[0038] In this embodiment, the number of the connecting members 23 is at least two, and they are symmetrically arranged on both sides of the housing 21 to ensure the stability of the housing 21. The connecting member 23 includes two first connecting ear plates 231 arranged on at least two opposite inner side edges of the housing 21, an external threaded column 232 arranged on the first connecting ear plate 231, a hanging plate 233 screwed on the external threaded column 232, a second connecting ear plate 234 arranged on the inner side edge of the lower positioning plate 13 of the positioning box body 1 and used for supporting the hanging plate 233, and a limit nut 235 screwed on the external threaded column 232 and used for clamping the hanging plate 233. It can be understood that the entire structure of the connecting member 23 is located in the space outside the installation positions of the anchor bolts a to avoid interfering with the installation of the anchor bolts.

[0039] In this embodiment, the casting mold 24 includes a flat plate 241 detachably installed at the upper end of the housing 21, a mounting hole 242 arranged on the flat plate 241 and matching with the opening 22, a casting cylinder 243 slidably connected in the mounting hole 242 and passing through the opening 22, a limit plate 244 arranged on the flat plate 241 and located at the side end of the mounting hole 242, a first threaded hole 245 arranged on the limit plate 244, a first adjusting screw 246 arranged at the upper end of the casting cylinder 243 and screwed with the first threaded hole 245, a handle 247 arranged at the end of the first adjusting screw 246, and a level 248 arranged on the flat plate 241.

[0040] It should be noted that the number of the flat plates 241 corresponds to the number of the casting cylinders 243 installed at one time. Therefore, the number of the flat plates 241 can be single or multiple, and preferably multiple to improve the casting efficiency. And multiple flat plates can be connected to each other to form a mesh structure to improve the structural strength of the device.

[0041] As a further preference of this embodiment, the upper end of the casting cylinder 243 has an opening, and a cross bar 243a for connecting the first adjusting screw 246 is arranged on the opening. The advantage of such a setting is that it is convenient to inject filling materials into the casting layer 243 to form a leveling layer b.

[0042] As a further preference of this embodiment, the flat plate 241 includes a plate body 241a, two side plates 241b disposed at both side ends of the plate body 241a and respectively connected to two side edges of the frame body 21, second threaded holes 241c disposed on the side plates 241b, and second adjusting screws 241d screwed on the second threaded holes 241c.

[0043] The working principle of the positioning device provided in this embodiment is as follows:

[0044] (1) After determining the installation position of the anchor bolt a, the casting mold 24 is installed at the lower end of the positioning box body 1 through the connecting member 23. The specific installation method is as follows: Rotate the hanging plate 233 to a suitable height on the external threaded column 232, then place the hanging plate 233 on the upper end of the second connecting ear plate 234, and finally tighten the limit nut 235 to fix the hanging plate 233, and the frame body 21 is fixed.

[0045] (2) Install the casting mold 24 on the frame body 21. The specific method is as follows: First, make the mounting holes 242 on the flat plate 241 correspond to and match the openings 22 one by one, and then rotate the second adjusting screw 241d to complete the fixation of the flat plate 241 on the frame body 21.

[0046] (3) Pour the leveling layer. The specific method is as follows: Screw a plurality of casting cylinders 243 into the openings 22 one by one through the screwing connection of the first adjusting screws 246 and the first threaded holes 245, and adjust the depth of each casting cylinder 243 screwed in until the level 248 on the flat plate 241 shows horizontal. At this time, pour concrete into the cylinder through the opening at the upper end of the casting cylinder 243, and stop when the surface of the concrete is flush with the upper end of the opening 22, and wait for the concrete to solidify to form the leveling layer b.

[0047] (4) Remove all the casting cylinders 243 and the flat plate 241.

[0048] (5) Install all the anchor bolts a in place: During installation, the anchor bolts a pass through the positioning holes 11 and the openings 22 on the two positioning plates at one time until the ends are connected to the surface of the leveling layer b, and the installation height of the anchor bolts a is determined by the fixing nuts.

[0049] (6) Loosen the limit nut 235, rotate the hanging plate 233 up and down on the external threaded column 232 until the frame body 21 is driven to the lower positioning plate 13, and then tighten the limit nut 235 again.

[0050] (7) Bind the reinforcement bars in the middle and lower parts of the anchor bolts a. After the installation is completed, pour concrete. After the concrete begins to set, remove the positioning box body 1 together with the frame body 21 for turnover use.

[0051] The positioning device provided in this embodiment has the following advantages compared with the prior art: First, it can pour the leveling layer at the installation position of the anchor bolts by itself, and the leveling layer is distributed in a point-like manner, corresponding to the installation positions of the anchor bolts one by one. This not only avoids the cumbersome steps of repeated leveling but also reduces the pouring volume and pouring waiting time, further improving work efficiency. Second, the additional structures such as the pouring mold and connectors can be removed and reused after the work installation, greatly reducing the construction cost and having the advantage of strong practicability.

[0052] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
