Description

Technical Field

[0001] This utility model relates to the field of construction platform steel plate machinery technology, and in particular to a welding-free construction platform steel plate machinery anti-slip fixing device. Background Technology

[0002] In the construction of temporary construction platforms for building and bridge projects, steel plates are core components. In building projects, steel plates are frequently laid to form safe and reliable working surfaces for foundation pit support and horizontal temporary passages for main structure construction, as well as pier and column pouring platforms and temporary support surfaces for beam and slab installation in bridge projects. Moreover, these platforms need to be adjusted quickly as the construction process progresses. For example, when switching from foundation construction to main structure construction, the platform area needs to be expanded or contracted simultaneously, resulting in a very high frequency of steel plate laying.

[0003] Traditionally, when welding and fixing steel plates for construction platforms, the steel plates must be directly welded to the I-beams to form a rigid connection structure. In this way, once the welding is completed, the relative position of the steel plates and the I-beams is completely fixed. If it is necessary to replace steel plates of different sizes or adjust the laying spacing and position of the steel plates to meet the operational requirements during subsequent construction, it is impossible to operate directly. The original welds must be ground and removed before re-welding, which is not only cumbersome but also easily damages the surface integrity of the components. Therefore, it is necessary to propose a welding-free mechanical anti-slip fixing device for construction platform steel plates. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing technology, steel plates are directly welded to I-shaped distribution beams to form a rigid connection structure. If different sizes of steel plates need to be replaced or the laying spacing and position of the steel plates need to be adjusted to meet the operation requirements in subsequent construction, the original weld seams can only be ground and removed and then re-welded. Therefore, a mechanical anti-slip fixing device for steel plates of a welding-free construction platform is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mechanical anti-slip fixing device for a weld-free construction platform steel plate is used to fix an I-shaped distribution beam and a construction steel plate, including an anti-slip fixing mechanism between the I-shaped distribution beam and the construction steel plate;

[0007] The anti-slip fixing mechanism includes:

[0008] The system includes a bidirectional lead screw, a bent reinforcing bar, and a locking plate. The bent reinforcing bar and the locking plate are fixedly connected. The bidirectional lead screw and the L-shaped locking plate are threadedly connected. When the bidirectional lead screw rotates, it drives two sets of L-shaped locking plates to move in opposite directions to clamp and fix them inside the I-shaped distribution beam.

[0009] The L-shaped locking plate is internally connected to a limiting slide plate, and a one-way screw is rotatably connected to the limiting slide plate. The one-way screw and the moving plate are threaded together. When the one-way screw rotates, it drives the moving plate to move, so that the locking plate presses and fixes the construction steel plate.

[0010] The locking bolt is threaded into the threaded hole of the L-shaped locking plate.

[0011] The above technical solution further includes:

[0012] Specifically, a hexagonal nut is fixedly connected to the outer side of the bidirectional lead screw, and there are two sets of L-shaped locking plates. The interior of each set of L-shaped locking plates is provided with a sliding groove, and the sliding grooves of each set are slidably connected to the limiting slide plate.

[0013] Specifically, a connecting plate is fixedly connected to the outer side of the limiting slide plate, and the connecting plate is rotatably connected to the one-way screw. The side of the moving plate near the construction steel plate is fixedly connected to the bent reinforcing bar, and the end of the bent reinforcing bar away from the moving plate is fixedly connected to the locking plate.

[0014] Specifically, a limiting rod is fixedly connected to the side of the connecting plate near the construction steel plate, and the limiting rod is slidably connected to the moving plate.

[0015] Specifically, there are multiple sets of threaded holes, which are arranged linearly and evenly along the L-shaped locking plate, and the threaded holes are threadedly connected to the locking bolts.

[0016] Specifically, the locking plate has anti-slip serrations on the side facing the construction steel plate, and the anti-slip serrations are evenly distributed along the length of the locking plate.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, an L-shaped locking plate is driven by a bidirectional screw to clamp the I-shaped distribution beam. The sliding groove adjusts the position of the limiting slide plate and locks the multiple sets of linearly distributed threaded holes. This allows for flexible adaptation to construction steel plates of different sizes, avoiding the problems of difficult disassembly and adjustment in traditional welding methods. On-site installation and adjustment can be completed with only simple tools such as wrenches, significantly shortening the construction preparation time and making it highly practical.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1-4 As shown, the present invention proposes a mechanical anti-slip fixing device for a weld-free construction platform steel plate, which is used to fix an I-shaped distribution beam 1 and a construction steel plate 2, including an anti-slip fixing mechanism between the I-shaped distribution beam 1 and the construction steel plate 2.

[0027] The anti-slip fixing mechanism includes:

[0028] The double-ended screw rod 3, the bent steel bar 7 and the locking plate 8 are fixedly connected. The double-ended screw rod 3 and the L-shaped locking plate 302 are threadedly connected. When the double-ended screw rod 3 rotates, it drives the two sets of L-shaped locking plates 302 to move in opposite directions to clamp and fix them on the inside of the I-shaped distribution beam 1.

[0029] The L-shaped locking plate 302 is internally connected to a limiting slide plate 4. A one-way screw 6 is rotatably connected to the limiting slide plate 4. The one-way screw 6 and the moving plate 601 are threaded together. When the one-way screw 6 rotates, it drives the moving plate 601 to move, so that the locking plate 8 presses and fixes the construction steel plate 2.

[0030] The locking bolt 5 is threaded into the threaded hole 304 of the L-shaped locking plate 302.

[0031] Furthermore, the anti-slip fixing mechanism is connected and fixed to the I-shaped distribution beam 1 by means of the bidirectional screw 3: when the bidirectional screw 3 is rotated, due to the threaded engagement characteristics between the bidirectional screw 3 and the two sets of L-shaped locking plates 302, the two sets of L-shaped locking plates 302 move in opposite directions along the axial direction of the bidirectional screw 3, and finally clamp on the inner side of the I-shaped distribution beam 1, thus completing the installation and positioning of the anti-slip fixing mechanism on the I-shaped distribution beam 1.

[0032] According to the size requirements of the construction steel plate 2, adjust the position of the limiting slide plate 4 inside the L-shaped locking plate 302 to match the fixing range of the construction steel plate 2; after the adjustment is in place, tighten the locking bolt 5 so that it abuts against the limiting slide plate 4 through the threaded hole 304, lock the position of the limiting slide plate 4, and ensure the stability of subsequent fixing operations.

[0033] The construction steel plate 2 is pressed and fixed by driving the one-way screw 6: When the one-way screw 6 is rotated, the moving plate 601 moves axially along the one-way screw 6 under the threaded engagement between the one-way screw 6 and the moving plate 601, thereby driving the associated bent steel bar 7 to move synchronously, and finally causing the locking plate 8 connected to the other end of the bent steel bar 7 to tightly press the construction steel plate 2, thereby achieving anti-slip fixation of the construction steel plate 2 on the I-shaped distribution beam 1.

[0034] A hexagonal nut 301 is fixedly connected to the outer side of the double-acting screw 3. There are two sets of L-shaped locking plates 302. The interior of each set of L-shaped locking plates 302 is provided with a sliding groove 303. Both sets of sliding grooves 303 are slidably connected to the limiting slide plate 4.

[0035] Furthermore, by clamping and rotating the hexagonal nut 301 with a wrench or other tools, the bidirectional lead screw 3 can be easily driven to rotate. As the bidirectional lead screw 3 rotates, the two sets of L-shaped locking plates 302 move in opposite directions along the axis of the bidirectional lead screw 3 under the action of the threads, thereby clamping and fixing the I-shaped distribution beam 1. When it is necessary to adjust the position of the limiting slide plate 4 to adapt to construction steel plates 2 of different sizes, the sliding groove 303 inside the L-shaped locking plate 302 provides sliding guidance for the limiting slide plate 4, ensuring that the limiting slide plate 4 maintains a stable trajectory during movement and avoids deviation.

[0036] A connecting plate 401 is fixedly connected to the outer side of the limiting slide plate 4. The connecting plate 401 is rotatably connected to the one-way screw 6. The side of the moving plate 601 closest to the construction steel plate 2 is fixedly connected to the bent steel bar 7. The end of the bent steel bar 7 away from the moving plate 601 is fixedly connected to the locking plate 8.

[0037] Furthermore, once the position of the limiting slide plate 4 is adjusted and locked, the connecting plate 401 on its outer side provides a stable rotational support base for the one-way screw 6, ensuring that the one-way screw 6 maintains axial stability during rotation and avoids shaking.

[0038] When the one-way lead screw 6 is rotated, it drives the moving plate 601 to move axially through its own rotation, converting the rotational motion of the one-way lead screw 6 into linear thrust, and driving the bent steel bar 7 connected to it to move synchronously.

[0039] The bent steel bar 7, by virtue of its own rigidity, transmits the thrust of the moving plate 601 to the locking plate 8 at the other end, so that the locking plate 8 can act on the surface of the construction steel plate 2. The locking plate 8, by increasing the contact area with the construction steel plate 2, evenly distributes the force transmitted by the bent steel bar 7 onto the construction steel plate 2, thereby achieving a stable compression and fixation of the construction steel plate 2.

[0040] A limiting rod 602 is fixedly connected to the side of the connecting plate 401 near the construction steel plate 2, and the limiting rod 602 is slidably connected to the moving plate 601.

[0041] Furthermore, when the one-way screw 6 rotates and drives the moving plate 601 to move axially, the connecting plate 401 provides a stable guiding foundation for it through the fixed limiting rod 602, ensuring that the position of the limiting rod 602 is fixed. The limiting rod 602 restricts the moving plate 601 from rotating with the one-way screw 6, forcing the moving plate 601 to move linearly only along the axial direction of the limiting rod 602.

[0042] There are multiple sets of threaded holes 304, which are arranged linearly and evenly along the L-shaped locking plate 302. The threaded holes 304 are threadedly connected to the locking bolts 5.

[0043] Furthermore, after the limiting slide plate 4 is adjusted to the position of the construction steel plate 2 within the L-shaped locking plate 302, it needs to be locked by the locking bolt 5. Multiple sets of threaded holes 304 that are linearly and evenly distributed along the L-shaped locking plate 302 provide multiple locking point selections. According to the specific adjustment position of the limiting slide plate 4, the appropriate threaded hole 304 can be selected, and the locking bolt 5 can be screwed into the selected threaded hole 304 and tightened. The locking bolt 5 uses the axial force generated by the threaded engagement to press against the limiting slide plate 4 and lock its position.

[0044] The locking plate 8 has anti-slip serrations on the side facing the construction steel plate 2, and the anti-slip serrations are evenly distributed along the length of the locking plate 8.

[0045] Furthermore, the anti-slip serrations evenly distributed along the length of the locking plate 8 can significantly increase the friction between the locking plate 8 and the construction steel plate 2, preventing relative sliding between the two after they are pressed and fixed due to external forces such as vibration and personnel movement during construction.

[0046] In this embodiment, the specific implementation is as follows: During the operation of the mechanical anti-slip fixing device for the steel plate of the welding-free construction platform, firstly, the hexagonal nut 301 on the outside of the bidirectional screw 3 is clamped and rotated using tools such as a wrench, driving the bidirectional screw 3 to rotate. Because the bidirectional screw 3 is threadedly engaged with the two sets of L-shaped locking plates 302, the two sets of L-shaped locking plates 302 move in the opposite direction along the axial direction of the bidirectional screw 3 and are clamped to the inside of the I-shaped distribution beam 1, completing the installation and positioning of the anti-slip fixing mechanism on the I-shaped distribution beam 1. Then, according to the size requirements of the construction steel plate 2, the position of the limiting slide plate 4 is adjusted along the sliding groove 303 inside the L-shaped locking plate 302. The sliding groove 303 provides a stable guide for the limiting slide plate 4 to avoid displacement. After the adjustment is in place, according to the position of the limiting slide plate 4, a suitable point is selected from the multiple sets of linearly and evenly distributed threaded holes 304 on the L-shaped locking plate 302, and the locking bolt 5 is screwed into the threaded hole 304 and tightened. The axial force generated by the threaded engagement is used to press against the limiting slide plate 4 to lock its position.

[0047] The connecting plate 401 on the outer side of the limiting slide plate 4 provides stable rotation support for the one-way screw 6. When the one-way screw 6 is rotated, the limiting rod 602 fixed on the connecting plate 401 restricts the moving plate 601 from rotating with the one-way screw 6, forcing the moving plate 601 to move linearly along the axis of the limiting rod 602. The moving plate 601 drives the bent steel bar 7 connected to it to move synchronously. The bent steel bar 7 transmits the thrust to the locking plate 8 at the other end by means of its own rigidity, so that the locking plate 8 fits against the surface of the construction steel plate 2. The anti-slip teeth evenly distributed along the length direction on the side of the locking plate 8 facing the construction steel plate 2 significantly increase the friction of the contact surface between the two, avoiding relative sliding due to external forces such as construction vibration and personnel movement, and realizing the stable and anti-slip fixation of the construction steel plate 2 on the I-shaped distribution beam 1.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
