Description

Technical Field

[0001] This utility model belongs to the field of construction equipment technology, specifically a temporary support and fixing device for steel beams. Background Technology

[0002] In steel structure construction, temporary support devices are often required for the installation of steel beams. Most support devices are one-piece structures, and their length cannot be flexibly adjusted according to the installation height of the steel beams. If different heights need to be accommodated, the entire set of devices must be replaced, which is cumbersome and costly. Some splicable devices require multiple tightening with bolt sets, resulting in low splicing efficiency and difficulty in disassembly due to bolt corrosion. Moreover, the base plate is often designed with a fixed area. When used on soft ground (such as unpaved construction sites), the support area is often too small, leading to insufficient load-bearing capacity per unit area and causing the device to sink. This not only affects the installation accuracy of the steel beams but may also create safety hazards. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a temporary support and fixing device for steel beams, which effectively solves the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temporary support and fixing device for steel beams, comprising a main base plate, a support cylinder fixedly connected to the middle of the top of the main base plate, a first screw hole and a second screw hole respectively opened around the top of the main base plate, T-shaped rods fixedly connected around the top of the main base plate, L-shaped plates movably sleeved on the outside of the four T-shaped rods, a secondary base plate fixedly connected to the bottom of the four L-shaped plates, locking bolts threadedly connected inside the four L-shaped plates, the locking bolts threadedly connected to the first screw hole, a threaded sleeve threadedly connected to the upper outside of the support cylinder, and a connecting mechanism provided inside the support cylinder.

[0005] Preferably, the connecting mechanism includes a first support rod and a second support rod. The top end of the first support rod extends through to the top of the support cylinder, and the second support rod is located above the first support rod. The top end of the first support rod has a first slot, and the bottom end of the second support rod has a second slot. The first slot and the second slot are provided with the same trapezoidal block inside.

[0006] Preferably, a first rectangular groove is provided through one side of the trapezoidal block and one side of the second support rod, and a T-shaped plug is movably inserted into the first rectangular groove, with one side of the T-shaped plug extending through to the outside of the second support rod.

[0007] Preferably, the top of the T-shaped plug has a second rectangular groove through which an L-shaped plug is movably inserted, and the bottom of the L-shaped plug extends through to the bottom of the T-shaped plug.

[0008] Preferably, the support cylinder is externally fixedly connected with four reinforcing rods arranged in a circular array, and the bottom end of the reinforcing rods is fixedly connected to the top end of the main base plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model fixes the first and second support rods by placing the second support rod at the top of the first support rod, then inserting the trapezoidal block into the first and second slots, inserting the T-shaped plug into the first rectangular slot to limit the trapezoidal block and the second support rod, and finally inserting the L-shaped plug into the second rectangular slot. No welding is required, the assembly and disassembly efficiency is high, and it can be reused in multiple construction scenarios, reducing construction costs. 2. This new type of device uses a rotating locking bolt to move the locking bolt away from the first screw hole. Then, the L-shaped plate is rotated, and the L-shaped plate drives the sub-base plate to unfold. Then, the locking bolt is reversed so that the threads of the locking bolt extend into the interior of the second screw hole. The sub-base plate can be unfolded to make the support area flexible and adjustable. When constructing on soft ground, it effectively prevents the device from sinking. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0013] Example 1, by Figures 1-3 The present invention includes a main base plate 1, a support cylinder 2 fixedly connected to the middle of the top of the main base plate 1, a first screw hole 5 and a second screw hole 6 respectively opened around the top of the main base plate 1, T-shaped rods 3 fixedly connected around the top of the main base plate 1, L-shaped plates 4 movably sleeved on the outside of the four T-shaped rods 3, a secondary base plate 11 fixedly connected to the bottom of the four L-shaped plates 4, locking bolts 10 threadedly connected inside the four L-shaped plates 4, the locking bolts 10 threadedly connected to the first screw hole 5, a threaded sleeve 8 threadedly connected to the upper outside of the support cylinder 2, and a connecting mechanism 9 provided inside the support cylinder 2.

[0014] The connecting mechanism 9 includes a first support rod 901 and a second support rod 902. The top end of the first support rod 901 extends through to the top of the support cylinder 2. The second support rod 902 is located above the first support rod 901. A first slot 903 is provided at the top end of the first support rod 901, and a second slot 904 is provided at the bottom end of the second support rod 902. The same trapezoidal block 905 is provided inside the first slot 903 and the second slot 904. A first rectangular groove 908 is provided through one side of the trapezoidal block 905 and one side of the second support rod 902. A T-shaped insert 906 is movably inserted into the first rectangular groove 908. One side of the T-shaped insert 906 extends through to the outside of the second support rod 902.

[0015] On one side of the trapezoidal locking block 905 and the corresponding side of the second support rod 902, a first rectangular groove 908 is provided through and aligned. A T-shaped plug 906 is movably inserted into the first rectangular groove 908. The horizontal part of the T-shaped plug 906 is in close contact with the inner wall of the first rectangular groove 908, and one end of it extends through to the outside of the second support rod 902. By inserting it into the first rectangular groove 908, the relative movement of the trapezoidal locking block 905 and the second support rod 902 in the horizontal direction can be restricted. A second rectangular groove 909 is provided through the top of the T-shaped plug 906. An L-shaped plug 907 is movably inserted into the groove. The bottom end of the L-shaped plug 907 extends downward to the bottom of the T-shaped plug 906 and abuts against the outer wall of the first support rod 901. Through the limiting effect of the L-shaped plug 907, the T-shaped plug 906 is prevented from accidentally sliding out of the first rectangular groove 908, forming a secondary locking to ensure the reliability of the overall connection structure.

[0016] The top of the T-shaped insert 906 is provided with a second rectangular groove 909, and an L-shaped insert 907 is movably inserted into the second rectangular groove 909. The bottom end of the L-shaped insert 907 extends through to the bottom of the T-shaped insert 906. The support cylinder 2 is fixedly connected to the outside with four reinforcing rods 7, which are arranged in a ring array. The bottom end of the reinforcing rods 7 is fixedly connected to the top of the main base plate 1.

[0017] The triangular support structure formed by the reinforcing rod 7 can effectively disperse the radial and axial forces borne by the support cylinder 2, preventing the support cylinder 2 from tilting or deforming due to uneven force, and further ensuring the stability of the overall structure of the equipment.

[0018] Working principle: In use, first place the main base plate 1 horizontally on the ground, rotate the locking bolt 10 to move it away from the first screw hole 5, then rotate the L-shaped plate 4, which causes the secondary base plate 11 to unfold. Then reverse the locking bolt 10 so that the thread of the locking bolt 10 extends into the interior of the second screw hole 6. Place the second support rod 902 on the top of the first support rod 901, then insert the trapezoidal block 905 into the first slot 903 and the second slot 904 to fix the first support rod 901 and the second support rod 902. Then insert the T-shaped insert 906 into the first rectangular slot 908 to limit the trapezoidal block 905 and the second support rod 902. Finally, insert the L-shaped insert 907 into the second rectangular slot 909. Finally, insert the first support rod 901 into the interior of the support cylinder 2. By rotating the threaded sleeve 8, the threaded sleeve 8 moves upward, reducing the diameter of the top of the support cylinder 2 and limiting the first support rod 901.
