Abstract
Description
Technical Field
[0001] The utility model belongs to the construction industry, and more specifically relates to a foundation bolt positioning device. Background Art
[0002] At present, the positioning of anchor bolts in the construction industry mainly relies on steel bars, that is, fixing the anchor bolts on the steel bars in the foundation short column. Because the steel bars will cause a certain deformation due to external forces, the anchor bolts will be displaced. During construction, it is necessary to repeatedly measure and confirm the position of the anchor bolts to avoid the inability to install the upper steel structure of the anchor bolts after the foundation short column is poured. Each column foot must have 6 or even more anchor bolts. Repeatedly measuring the positioning of each anchor bolt is very troublesome and affects the construction period. Utility Model Content
[0003] The utility model is aimed at the above problems and provides an anchor bolt positioning device.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a main frame, a sub-frame and a positioning block, the sub-frame is arranged in the hollow space inside the main frame, the two ends of the sub-frame extend into the two opposite edge sealings of the main frame, and are slidably connected to the main frame, the inner edge of the main frame is drawn with a scale with millimeter accuracy, the positioning block is a "groove-type" structure, is clamped on the outside of the sub-frame, and is slidably connected to the sub-frame.
[0005] A long groove is opened in the middle of the sub-frame, and the inner wall of the long groove is marked with scales with millimeter accuracy.
[0006] The inner wall of the positioning block fits tightly with the outer side of the sub-frame so that it is stuck on the sub-frame and can move laterally along the sub-frame. A round hole is opened in the center of the positioning block, and the inner diameter of the round hole is slightly larger than the diameter of the anchor bolt; so that it can just fit into the anchor bolt with a small gap; the positioning block has strip holes on both sides of the round hole to facilitate viewing the scale through the hole.
[0007] Magnetic stickers are provided at the bottom of the two short sides of the sub-frame and the top of the two long sides.
[0008] The main frame is made of steel plates, and the outer edges are welded with upright steel sheets for edge sealing. The inner diameter of the main frame should be larger than the size of the concrete short column at the base of a general steel structure column.
[0009] The sub-frame is made of wooden strips, and the width of the long strip grooves in the sub-frame is greater than the diameter of the anchor bolts.
[0010] Beneficial effects of the utility model:
[0011] The utility model has the advantages of simple structure, durability, convenient installation and disassembly, and can quickly detect whether the positioning of the anchor bolts is accurate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] Depend on Figure 1-4 It can be seen that the utility model includes a main frame, a sub-frame and a positioning block. The sub-frame is arranged in the hollow space inside the main frame. The two ends of the sub-frame extend into the two opposite edge sealings of the main frame and are slidably connected to the main frame. The inner edge of the main frame is drawn with scales with millimeter accuracy. The positioning block is a "groove-type" structure, which is clamped on the outside of the sub-frame and is slidably connected to the sub-frame.
[0018] A long groove is opened in the middle of the sub-frame, and the inner wall of the long groove is marked with scales with millimeter accuracy.
[0019] The inner wall of the positioning block fits tightly with the outer side of the sub-frame so that it is stuck on the sub-frame and can move laterally along the sub-frame. A round hole is opened in the center of the positioning block, and the inner diameter of the round hole is slightly larger than the diameter of the anchor bolt; so that it can just fit into the anchor bolt with a small gap; the positioning block has strip holes on both sides of the round hole to facilitate viewing the scale through the hole.
[0020] Magnetic stickers are provided at the bottom of the two short sides of the sub-frame and the top of the two long sides.
[0021] The main frame is made of steel plates, and the outer edges are welded with upright steel sheets for edge sealing. The inner diameter of the main frame should be larger than the size of the concrete short column at the base of a general steel structure column.
[0022] The sub-frame is made of wooden strips, and the width of the long strip grooves in the sub-frame is greater than the diameter of the anchor bolts.
[0023] When using, first select a suitable bolt positioning block according to the construction drawing. The inner diameter of the positioning block is slightly larger than the bolt diameter. Then, according to the positioning size of the anchor bolt in the construction drawing, slide the sub-frame and the positioning block to adjust the positioning, and bond it to the main frame through the magnetic sheet. Insert the assembled device into the anchor bolt to complete the test. If the anchor bolt can completely pass through the inner hole of the positioning block, it means that the bolt is positioned accurately and does not need to be corrected. Otherwise, the anchor bolt positioning needs to be recalibrated.
