Description

Technical Field

[0001] The utility model relates to the field of embedded anchor bolts, in particular to an embedded fixing device for steel structure anchor bolts. Background Art

[0002] The embedding of steel structure anchor bolts plays a major role in the installation and construction process of steel columns of steel structures. Moreover, as the height and span of steel structures are getting larger and larger, the steel bar reinforcement of the concrete columns at the bottom of steel columns is also more intensive. Higher requirements are put forward for the embedded welding process of steel structure anchor bolts under traditional construction conditions and techniques. In the past construction process of embedding steel structure anchor bolts, the construction of the concrete foundation was considered first. Only after the construction of the foundation at the bottom of the steel column was completed could the positioning, embedding, welding, fixing and other processes of the anchor bolts be considered. Due to the increasing density of the short column steel bars at the bottom of the steel column, great difficulties are brought to the above processes, especially the embedded welding stage. Especially when the embedded depth of the anchor bolts in the short column is relatively large, the construction difficulty is further increased. When using traditional welding for positioning construction, the space is narrow, and high requirements are placed on the welding process and the construction level of welders. The one-time success rate of embedded welding is relatively low, and the position needs to be continuously corrected and adjusted later to ensure the accurate installation position of the anchor bolts. Therefore, how to effectively reduce the embedding difficulty and improve the construction efficiency of embedding steel structure anchor bolts has become an urgent problem to be solved in the construction process of steel structures and steel-concrete structures.

[0021] Refer to Figure 1 and Figure 2, the utility model relates to a pre-embedded fixing device for a steel structure anchor bolt 3. The main structure includes a support base 1, which is generally made of metal material and plays a role in horizontal load-bearing. A plurality of legs 2 capable of moving up and down relative to it are provided at the bottom of the support base 1. Fixing holes are provided at the bottom of the legs 2 for fixing them on the concrete foundation by passing bolts through the fixing holes. The legs 2 can move up and down relative to the support base 1, so that the height of the support base 1 can be adaptively adjusted according to actual use requirements, greatly improving the adaptability of the support base 1 to bear the anchor bolt 3. A plurality of anchor bolts 3 are fixedly welded or integrally formed at the top of the support base 1. A horizontal support frame 4 is provided between the middles of the plurality of anchor bolts 3. The horizontal support frame 4 fixes the relative positions between the plurality of anchor bolts 3, reducing the situation where the anchor bolts 3 are completely misaligned. Specifically, the horizontal support frame 4 is in an X shape, and its ends are respectively welded and fixed to the middles of the plurality of anchor bolts 3. A longitudinal support 5 is provided between the tops of adjacent anchor bolts 3. Generally, one longitudinal support 5 is used in cooperation with two or more anchor bolts 3 on the same straight line. Transverse supports 6 are symmetrically provided between the longitudinal supports 5. The transverse supports 6 are used to adjust the distance between adjacent two longitudinal supports 5. A longitudinal adjustment groove 7 is provided inside the longitudinal support 5. The longitudinal adjustment groove 7 runs through the longitudinal support 5 vertically. The top of the anchor bolt 3 is slidably connected in the longitudinal adjustment groove 7. A locking nut 8 for cooperating with the longitudinal support 5 is provided on the anchor bolt 3. With such a structure, when the distance between adjacent anchor bolts 3 needs to be adjusted, the anchor bolt 3 can be slid and fixed by the locking nut 8, so that the positions between the plurality of anchor bolts 3 on the same straight line can be quickly adjusted and fixed. The sliders 9 are symmetrically and slidably connected to the transverse support 6. The sliders 9 are movably connected to the longitudinal support 5. Specifically, detachable connection methods such as plugging or clamping can be adopted. A power rod 10 for driving the sliders 9 to slide is provided on the transverse support 6. With such a structure, the power rod 10 is used to drive the sliders 9 to slide on the transverse support 6, so that the longitudinal supports 5 connected to the sliders 9 move relative to each other, and then the distance between multiple groups of anchor bolts 3 is quickly adjusted. Such a structure enables the distance between multiple groups of anchor bolts 3 or between multiple anchor bolts 3 in each group to be quickly adjusted, greatly improving the efficiency and convenience of adjusting the relative positions of the anchor bolts 3, reducing the limitation of the foundation pit size on the pre-embedded construction of the anchor bolts 3, and improving the efficiency and accuracy of the pre-embedded construction of the anchor bolts 3.

[0022] Preferably, a plurality of adjusting rods 11 and guiding rods 12 are provided on the support base 1. The adjusting rods 11 are rotatably connected to the bottom of the support base 1 through bearings. The adjusting rods 11 penetrate through one of the legs 2 and are threadedly connected thereto. The guiding rods 12 are fixedly connected to the support base 1 by welding or integrally formed. The guiding rods 12 penetrate through the other leg 2 and are slidably connected thereto. With such a structure, only by rotating the adjusting rods 11 at certain positions, the support base 1 can be driven to move up and down along the plurality of guiding rods 12 under the action of the threaded connection, thereby realizing the quick and accurate adjustment operation of the height of the support base 1. The structure is simple, and the position of the support base 1 is more stable after adjustment.

[0023] Preferably, referring to Figure 3 , a transverse adjusting groove 13 is provided on the transverse support 6. The horizontal adjusting groove penetrates through the transverse support 6 vertically. The slider 9 is slidably connected in the transverse adjusting groove 13. Fixed blocks 14 are symmetrically welded or integrally formed and fixed in the longitudinal adjusting groove 7. The fixed blocks 14 are movably connected to the slider 9. With such a structure, the slider 9 can slide in the transverse adjusting groove 13 to realize the sliding movement relative to the transverse support 6. At the same time, the slider 9 is movably inserted into the fixed block 14 inside the longitudinal adjusting groove 7 on the longitudinal support 5, making the movable connection between the slider 9 and the longitudinal support 5 more stable and more convenient and rapid when connecting or separating.

[0024] Preferably, a fixing rod 15 is provided on the fixed block 14. After passing through the fixed block 14, the fixing rod 15 is threadedly connected to the slider 9. With such a structure, only by aligning the slider 9 with the fixed block 14 and then threading the fixing rod 15 through the fixed block 14 and threadedly connecting it to the slider 9 can the quick connection or separation of the slider 9 and the fixed block 14 be realized, thereby making the movable connection operation between the slider 9 and the longitudinal support 5 faster and more accurate.

[0025] Preferably, referring to Figure 4 , the power rod 10 is rotatably connected to the transverse support 6 through a bearing. Two threaded areas with opposite helix directions are provided on the power rod 10. The two threaded areas respectively penetrate through the two sliders 9 and are threadedly connected thereto. When the power rod 10 rotates, due to the action of the two opposite threaded areas, the two sliders 9 can slide relative to or away from each other simultaneously, thereby simultaneously realizing the quick adjustment of the distance between the two longitudinal supports 5, further reducing the difficulty of the adjustment operation, simplifying the steps of the distance adjustment, and realizing the quicker and more accurate adjustment operation of the position of the anchor bolt 3.

[0026] Preferably, the locking cap 8 is threadedly connected to the anchor bolt 3. The thread existing on the anchor bolt 3 itself can be used for the threaded connection with the locking cap 8. The locking caps 8 are symmetrically arranged on the upper and lower sides of the longitudinal bracket 5. The locking caps 8 are in contact with the longitudinal bracket 5. When the locking caps 8 rotate, they can contact the upper and lower sides of the longitudinal bracket 5 to clamp the longitudinal bracket 5, thereby realizing the rapid adjustment of the position of the anchor bolt 3 relative to the longitudinal bracket 5. The structure is simple and the operation is convenient, further improving the convenience of adjusting the position of the anchor bolt 3.

[0027] Working principle: In the structure of the utility model, a plurality of legs 2 are arranged at the bottom of the support 1, and the legs 2 can move up and down relative to the support 1. A plurality of anchor bolts 3 are fixed to the top of the support 1. A horizontal support frame 4 is arranged between the middles of the plurality of anchor bolts 3. Such a structure enables the installation height of the anchor bolts 3 to be adaptively adjusted according to actual usage requirements. Moreover, the plurality of anchor bolts 3 are fixed and restricted by the horizontal support frame 4 to prevent the anchor bolts 3 from bending and misaligning, improving the efficiency and stability of the embedded construction of the anchor bolts 3; a longitudinal bracket 5 is arranged between the tops of adjacent anchor bolts 3, and transverse brackets 6 are symmetrically arranged between the longitudinal brackets 5. The anchor bolts 3 are slidably connected to the longitudinal adjustment grooves 7 of the longitudinal bracket 5.

A slider 9 is slidably connected to the transverse bracket 6, and the slider 9 is movably connected to the longitudinal bracket 5. By adjusting the position of the slider 9, the distance between adjacent longitudinal brackets 5 can also be adaptively adjusted. Such a structure can quickly adjust the distance between each other by the cooperation of the longitudinal bracket 5 and the transverse bracket 6 when the anchor bolts 3 are bent and misaligned, thereby greatly reducing the difficulty of adjusting the position of the anchor bolts 3 and improving the efficiency and convenience of the embedded construction of the anchor bolts 3.
