Description

Technical Field

[0001] This utility model relates to the field of roof steel beam installation technology, and in particular to an auxiliary support device for roof steel beam installation. Background Technology

[0002] Roof steel beams are indispensable load-bearing components in building roof structures, generally composed of welded steel sections or plates. They bear the loads of the roof, including the weight of the roof material itself, snow loads, wind loads, etc., and transfer these loads to the vertical load-bearing structures such as columns and walls, thereby ensuring the stability and safety of the entire roof structure.

[0003] In existing technologies, the installation of roof steel beams involves first installing steel columns, then using wedges, shims, and jacks for alignment. Simultaneously, lifting lugs are installed on the steel columns, secured with guy ropes, and inter-column supports and tie rods are installed to form a stable frame structure. Secondary grouting is then performed at the column bases, followed by concrete pouring at the apex. Steel beams within the stable zone are then installed, with lifting lugs and guy ropes installed on them for auxiliary support. However, the lifting lugs and guy ropes need to be removed later. Currently, this requires dismantling each lug and guy rope individually on the steel columns and beams, which is inefficient and has limitations. Therefore, a roof steel beam installation auxiliary support device needs to be designed to solve these problems. Utility Model Content

[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an auxiliary support device for the installation of roof steel beams, comprising:

[0033] Steel column 1, with steel beam 2 installed on top of steel column 1. Auxiliary support mechanisms are set on steel column 1 and steel beam 2. Through the set auxiliary support mechanisms, steel column 1 and steel beam 2 can be well supported and can be easily dismantled later, making them convenient to use.

[0034] The auxiliary support mechanism includes a first lifting lug 3, a second lifting lug 6, a connecting frame 9, a rotating shaft 10, a long positioning block 11, a short positioning block 12, and a stop plate 13;

[0035] The first lifting lug 3 is clamped to the steel column 1, and the second lifting lug 6 is clamped to the steel beam 2. It should be noted that the first lifting lug 3 and the second lifting lug 6 have the same specifications and are both T-shaped structures.

[0036] The connecting frame 9 is fixedly installed on the first lifting lug 3, and the rotating shaft 10 is rotatably installed on the connecting frame 9. The rotating shaft 10 is threadedly connected to the long positioning block 11. The long positioning block 11 can pass through the first lifting lug 3 and be engaged with the steel column 1. The short positioning block 12 can pass through the second lifting lug 6 and be engaged with the steel beam 2. The bottom of the abutment plate 13 is fixedly connected to the long positioning block 11, and the other end of the abutment plate 13 can press against the short positioning block 12.

[0037] Using the aforementioned auxiliary support mechanism, the first lifting lug 3 is inserted into the steel column 1. Rotating the shaft 10 causes the long positioning block 11 to partially engage with the long positioning groove of the steel column 1, thus fixing the first lifting lug 3 to the steel column 1. The steel beam 2 is then hoisted onto the steel column 1, and the second lifting lug 6 is inserted into the steel beam 2, causing the side of the short positioning block 12 to engage with the abutment plate 13. The shaft 10 is then rotated further, causing the long positioning block 11 to move the abutment plate 13, which in turn abuts the short positioning block 12 until the long positioning block 11 is fully engaged with the long positioning groove and the short positioning block 12 is fully engaged with the short positioning groove of the steel beam 2. This fixes the second lifting lug 6. Later, simply rotating the shaft 10 and pulling the short positioning block 12 allows for the removal of the first lifting lug 3, the second lifting lug 6, the first guy rope 4, and the second guy rope 7, making the operation relatively convenient.

[0038] Specifically, the auxiliary support mechanism also includes a first guy rope 4, a first steel rod 5, a second guy rope 7, and a second steel rod 8. The first guy rope 4 is fixedly installed on the first lifting lug 3 and is fixedly connected to the first steel rod 5. The second guy rope 7 is fixedly installed on the second lifting lug 6 and is fixedly connected to the second steel rod 8.

[0039] Using the aforementioned auxiliary support mechanism, the first guy rope 4 is pulled to insert the first steel rod 5 into the ground to provide auxiliary support for the steel column 1, and the second guy rope 7 is pulled to insert the second steel rod 8 into the ground to provide auxiliary support for the steel beam 2.

[0040] Specifically, the outer side of the rotating shaft 10 is provided with an external thread, and the long positioning block 11 is provided with a threaded groove. The external thread and the threaded groove are connected by a thread. A control lever is installed on the rotating shaft 10. By rotating the rotating shaft 10, the long positioning block 11 can be moved laterally.

[0041] Specifically, the top of the steel column 1 has a lower T-slot, and the top of the steel beam 2 has an upper T-slot 14. The first lifting lug 3 is engaged with the lower T-slot, and the second lifting lug 6 is engaged with the upper T-slot 14. A long positioning groove is provided on the side wall of the lower T-slot, and a long positioning block 11 is engaged with the long positioning groove. A short positioning groove is provided on the side wall of the upper T-slot 14, and a short positioning block 12 is engaged with the short positioning groove. It should be noted that this facilitates the fixing of the first lifting lug 3 and the second lifting lug 6 to the steel column 1 and the steel beam 2, respectively.

[0042] Specifically, the first lifting lug 3 has a first sliding hole on its side, and the long positioning block 11 is slidably installed in the first sliding hole. The second lifting lug 6 has a second sliding hole on its side, and the short positioning block 12 is slidably installed in the second sliding hole, so that the long positioning block 11 and the short positioning block 12 can move stably in the lateral direction.

[0043] Specifically, the bottom of the second lifting lug 6 is in contact with the first lifting lug 3, making it convenient to pull the first lifting lug 3 upwards and remove it later.

[0044] Working principle:

[0045] S1: Install steel column 1, use wedges, pads and jacks to align it, then insert the first lifting lug 3 into steel column 1, rotate the shaft 10 to move the long positioning block 11 a certain distance, so that the long positioning block 11 is partially inserted into the long positioning groove, thus fixing the first lifting lug 3 on steel column 1. Then pull the first guy rope 4 to insert the first steel rod 5 into the ground to provide auxiliary support for steel column 1.

[0046] S2: Install the support and tie rod between steel columns 1 to form a stable frame structure with steel columns 1, and grout the column base of steel columns 1 (not shown in the figure);

[0047] S3: Hoist the steel beam 2 onto the steel column 1, insert the second lifting lug 6 into the steel beam 2, so that the side of the short positioning block 12 fits against the abutment plate 13. Then continue to rotate the rotating shaft 10, the long positioning block 11 drives the abutment plate 13 to move, and the abutment plate 13 abuts against the short positioning block 12 until the long positioning block 11 is completely inserted into the long positioning groove and the short positioning block 12 is completely inserted into the short positioning groove. In this way, the second lifting lug 6 is fixed. Then pull the second guy rope 7 and insert the second steel rod 8 into the ground to provide auxiliary support for the steel beam 2.

[0048] S4: Later, you only need to rotate the shaft 10 and pull the short positioning block 12 to remove the first lifting lug 3, the second lifting lug 6, the first guy rope 4 and the second guy rope 7. The operation is relatively convenient.
