The connection between the steel structure column and the reinforcing bars is then poured to facilitate subsequent steel structure erection.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The welded steel structure columns cannot be fine-tuned in the event of installation errors, resulting in low installation efficiency.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0038] Combination Figure 1-2 As shown in the figure, this embodiment of the present disclosure provides a fixing device for the construction of a steel structure foundation, comprising: a pre-embedded base 100, an assembly base 200, a limiting ring plate 300, and an adjusting plate 400. A first adjusting sliding part 110 is fixedly provided on the top of the pre-embedded base 100; a second adjusting sliding part 210 is fixedly provided on the bottom of the assembly base 200, the second adjusting sliding part 210 being slidably connected to the first adjusting sliding part 110, and the top of the assembly base 200 being provided with an insertion groove 220 for inserting a vertical column; the limiting ring plate 300 is fixedly connected to the top of the pre-embedded base 100, and the limiting ring plate 300 is disposed on the outer side of the assembly base 200; multiple adjusting plates 400 are provided, each adjusting plate 400 being threadedly connected to the limiting ring plate 300, and each adjusting plate 400 being able to abut against the side wall of the assembly base 200; wherein, the multiple adjusting plates 400 are spaced apart around the axis of the limiting ring plate 300.

[0039] Using the fixing device for steel structure foundation construction provided in this embodiment, the pre-embedded base 100 is installed and fixed in the pouring pit, and then the upright column is inserted into the insertion slot 220 to fix the upright column. When the upright column is installed and connected to other parts of the steel structure, the positions of some or all of the multiple adjusting plates 400 can be adjusted so that the adjusting plates 400 can move relative to the limiting ring plate 300. The adjusting plates 400 provide lateral pressure to the assembly base 200, so that the first adjusting sliding part 110 and the second adjusting sliding part 210 slide relative to each other, thereby fine-tuning the angle and position of the upright column relative to the pre-embedded base 100. Moreover, the multiple adjusting plates 400 are spaced apart around the axis of the limiting ring plate 300, which can adjust the angle of the upright column in multiple directions. In case of installation errors, the upright column can be adjusted in time to meet the installation conditions and improve the installation efficiency.

[0040] Understandably, upright columns refer to vertical columns in steel structures.

[0041] Understandably, once the uprights and the rest of the steel structure are installed, no further adjustments are needed. Concrete can be poured onto both the inner and outer sides of the limiting ring plate 300 to improve the stability and strength of the support.

[0042] Combination Figure 3 As shown, optionally, the first adjusting sliding part 110 is a first sliding block 111, and the first sliding block 111 is provided with a first arc-shaped surface 112; the second adjusting sliding part 210 is a plurality of second sliding blocks 211, and each first sliding block 111 is provided with a second arc-shaped surface 212 that is slidably connected to the first arc-shaped surface 112. In this way, the first arc-shaped surface 112 and the second arc-shaped surface 212 can slide relative to each other, and the sliding directions are relatively numerous, so that the adjustable angle range between the mounting base 200 and the upright column and the pre-embedded base 100 is relatively large.

[0043] Optionally, two second sliding blocks 211 are provided, and the two second sliding blocks 211 are spaced apart, with the first arc-shaped surface 112 and the second arc-shaped surface 212 in contact. In this way, the interval between the two second sliding blocks 211 is relatively large, resulting in relatively high stability of the sliding between the second sliding block 211 and the first sliding block 111. The contact area between the first arc-shaped surface 112 and the second arc-shaped surface 212 is relatively large, further contributing to relatively high stability.

[0044] Specifically, the first sliding block 111 is fixedly connected to the pre-embedded base 100, and the second sliding block 211 is fixedly connected to the assembly base 200.

[0045] Optionally, both sides of the first sliding block 111 are provided with limiting blocks 120 that are fixedly connected to the pre-embedded base 100. Each limiting block 120 can abut against a second sliding block 211 to limit the relative sliding between the first sliding block 111 and the second sliding block 211. In this way, the limiting blocks 120 can limit the range of relative sliding between the first sliding block 111 and the second sliding block 211, preventing the tilt angle of the upright column from being too large and ensuring the support effect of the upright column.

[0046] Optionally, two limiting plates 130 are fixedly provided on the pre-embedded base 100, and the two limiting plates 130 are disposed on both sides of the first sliding block 111. Each limiting plate 130 can abut against the mounting base 200 to limit the relative sliding between the first sliding block 111 and the second sliding block 211. The connecting line of the two limiting plates 130 is perpendicular to the connecting line of the two limiting blocks 120. In this way, the limiting plates 130 and the limiting blocks 120 cooperate to limit the relative sliding range of the first sliding block 111 and the second sliding block 211 from multiple directions, avoiding excessive tilt angle of the upright column and ensuring the support effect of the upright column.

[0047] Combination Figure 4 As shown, optionally, the assembly base 200 is provided with a locking interface 230, and the plug-in rod 240 passes through the locking interface 230 and is plugged into the embedded base 100 to restrict the relative movement of the embedded base 100 and the assembly base 200. In this way, by plugging the plug-in rod 240 into the embedded base 100, the relative movement of the embedded base 100 and the assembly base 200 is restricted, and the relative sliding of the first adjusting sliding part 110 and the second adjusting sliding part 210 is also restricted, so that the upright column remains stable before being connected and installed with other parts of the steel structure. After the plug-in rod 240 is pulled out from the embedded base 100 and the locking interface 230, the restriction on the relative movement of the embedded base 100 and the assembly base 200 is released.

[0048] Optionally, the mounting base 200 includes: a base plate 250, a connecting seat 260, and a guide frame 270. A second adjusting sliding part 210 is fixedly provided at the bottom of the base plate 250, and the sidewall of the base plate 250 can abut against multiple adjusting plates 400. The connecting seat 260 is connected to the base plate 250 and has an insertion slot 220 for inserting into an upright column. The guide frame 270 is fixedly connected to the connecting seat 260 and is disposed outside the insertion slot 220. In this way, the upright column can be inserted into the insertion slot 220 along the guide frame 270, and the guide frame 270 can abut against the upright column, improving the stability of the connection.

[0049] Understandably, the upright column can be inserted into the insertion slot 220 to weld and fix the upright column and the connecting seat 260.

[0050] Optionally, the insertion slot 220 is an H-shaped slot. In this way, the shape of the insertion slot 220 corresponds to the shape of the steel structure column.

[0051] Optionally, the insertion slot 220 has multiple reinforcing ribs along its edge, each of which is fixedly connected to the connector 260. This increases the strength of the connector 260 and improves the stability of the connection with the upright column.

[0052] Combination Figure 5 As shown, optionally, a connecting sleeve 140 is fixedly provided at the bottom of the embedded base 100, and the connecting sleeve 140 is used to insert with the reinforcing bar 150. In this way, the connecting sleeve 140 and the reinforcing bar 150 are inserted into each other, the contact area is relatively large, the connection stability is relatively high, and the risk of displacement of the embedded base 100 is reduced.

[0053] Optionally, eight connecting sleeves 140 are provided. This results in a relatively large number of connecting sleeves 140, which in turn allows for a relatively large number of connecting steel bars 150 to be connected, further improving the stability of the connection.

[0054] Optionally, the embedded base 100 is provided with a downwardly extending edge plate 160, and the edge plate 160 is provided with a plurality of viewing holes 161. In this way, when pouring concrete, the concrete can flow through the plurality of viewing holes 161, so that the concrete and the edge plate 160 are poured together, resulting in relatively high strength.

[0055] Optionally, four adjustment plates 400 are provided. In this way, the number of adjustment plates 400 is large, which can provide lateral support for the assembly base 200 from multiple directions. The adjustment plates 400 that move relative to the limiting ring plate 300 can adjust the angle of the assembly base 200 relative to the pre-embedded base 100, which facilitates installation.

[0056] Optionally, each adjusting plate 400 is connected to a limiting ring plate 300 via a screw 410, with the screw 410 passing through the limiting ring plate 300. Thus, rotating the screw 410 on the limiting ring plate 300 adjusts the position of the corresponding adjusting plate 400 relative to the limiting ring plate 300, thereby adjusting the angle between the mounting base 200 and the pre-embedded base 100, facilitating installation.

[0057] Understandably, rotating one of the screws 410 reduces the gap between the corresponding adjusting plate 400 and the limiting ring plate 300, allowing the mounting base 200 to move towards the adjusting plate 400 being adjusted. The mounting base 200 then slides relative to the pre-embedded base 100 until it abuts against the adjusting plate 400. Rotating the other opposing screw 410 then gradually increases the gap between the corresponding adjusting plate 400 and the limiting ring plate 300 until the adjusting plate 400 abuts against the mounting base 200 again. Once all the adjusting plates 400 are in contact with the mounting base 200, the adjustment is complete.

[0058] Specifically, the adjusting plate 400 is a circular plate structure, and the plane on which the adjusting plate 400 is located is parallel to the axis of the limiting ring plate 300.

[0059] Optionally, a hexagonal block 420 is provided at the end of the screw 410 facing away from the adjusting plate 400. This makes it easy to turn the hexagonal block 420 with a wrench, thereby turning the screw 410.

[0060] Optionally, the embedded base 100 and / or the mounting base 200 are made of carbon steel. In this way, the embedded base 100 and / or the mounting base 200 have relatively high strength and good support effect.
