The inventor finds that aiming at the field of ocean engineering, a welding assembly bearing for a combined beam is needed to realize the support and pre-butt joint of a large-scale I-shaped combined beam of the ocean engineering, and the quality and the efficiency of subsequent welding are improved.

In view of this, referring to fig. 1 to 3, the i-shaped composite beam 8 includes two left and right parts, the center of the butt joint of the two parts is the welding position 7, and in the actual welding process, the two left and right parts are respectively placed in the two symmetrical clamping grooves 3. The embodiment provides a combination beam welding assembly bearing, which comprises a bottom frame 1 and at least two clamping plates 2, wherein a plurality of clamping plates 2 which are parallel to each other and distributed at intervals are arranged on the bottom frame 1, and the clamping plates 2 are used for supporting a large I-shaped combination beam 8 and realizing pre-butt joint. At the top edge of the clamping plate 2, at least two pairs of clamping grooves 3 which vertically extend from the center to two sides are symmetrically arranged, the clamping grooves 3 which are closer to the two sides are deeper, the depths of the two symmetrical clamping grooves 3 are the same, and the clamping grooves 3 with the same depth of the clamping plates 2 are positioned on the same straight line. As shown in fig. 3, the welding positions 7 of the left and right parts of the i-shaped composite beam 8 are the same as the height of the bottom of the composite beam, and the symmetrical clamping grooves 3 need the same depth, while for the i-shaped composite beams 8 with different sizes, the distances between the welding positions 7 and the left and right sides are different, so that a proper pair of clamping grooves 3 needs to be selected for supporting and pre-aligning. In particular, the spacing and depth of the clamping grooves 3 which are symmetrical in bearing are customized according to the size of the I-shaped combined beam 8 which is welded according to the requirement. In addition, when the height and width of the i-shaped composite beams 8 are the same, different lengths may exist, so that for different i-shaped composite beams 8 to be welded, more spaced clamping plates 2 can be additionally arranged on the underframe 1, and the overlong i-shaped composite beams 8 need to expand the underframe 1 and additionally arrange the clamping plates 2. In addition, after the i-shaped combined beam 8 is placed and clamped into the clamping groove 3, a steel wedge-shaped clamping piece is generally clamped between the i-shaped combined beam 8 and the clamping groove 3, so that the clamping groove is stable.

In some embodiments, the underframe 1 comprises two longitudinal beams 4 and at least two transverse beams 5, the transverse beams 5 are parallel to each other and are arranged at intervals, the transverse beams 5 are parallel to the plate surface of the clamping plate 2, and the two longitudinal beams 4 are respectively and vertically connected to two ends of each transverse beam 5, so that the relatively stable underframe 1 is formed by connection. It should be noted that, when the clamping plate 2 is installed, it is required to fix the clamping plate at the top of the cross beam 5 along the cross beam in a one-to-one correspondence manner, so as to ensure the stability of the whole structure.

Under some embodiments, because the I-shaped composite beam 8 is made of steel materials, the weight is very large, and the interval between any two adjacent clamping plates 2 or cross beams 5 of the composite beam welding pair support is equal, so that the uniformity of the stress of the whole support is ensured.

Under some embodiments, the underframe 1 further comprises a supporting column 6 arranged at the bottom of the joint of the cross beam 5 and the longitudinal beam 4 and used for supporting and lifting the whole underframe 1, the supporting column 6 is generally arranged at the joint of the cross beam 5 and the longitudinal beam 4 so as to ensure the best supporting strength, and the supporting columns 6 are required to be uniformly arranged on the underframe 1 and ensure uniform stress.

In some embodiments, the underframe 1 and the clamping plate 2 are made of high-strength carbon steel, and the plate thickness of the clamping plate 2 is larger than 10mm and is generally 15-25mm, so that the clamping plate has good supporting and bearing effects on the heavy I-shaped combined beam 8.

The above examples illustrate only one embodiment of the utility model, which is described in more detail and is not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
