[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, in the hot-rolled strip steel project, according to the process layout and production needs, a crane-free intermediate span 2 with an axis spacing of 9m is required to be arranged between the roller repair room and the main rolling span for maintenance, etc. The traditional structural facade method is: lattice steel columns 13 are set on both sides of the intermediate span 2 to bear the crane beams 9 on both sides and the roof load respectively. According to the existing traditional structural facade method, the traditional model uses about 75.3t of steel per frame, and the foundation concrete of a single frame requires 211.72m3.

[0025] Under the premise of ensuring the supporting performance of room 1, in order to save the amount of steel structure and concrete, Figure 1 As shown, embodiment 1 of the present invention provides a factory column arrangement structure with a process middle span 2 without a crane, comprising two factory rooms 1, a middle span 2 is arranged in the middle of the two factory rooms 1, first steel columns 3 are arranged on both sides of the middle span 2 for support, a shoulder beam 5 is arranged on the top of the first steel column 3 support, a second steel column 4 is arranged on the shoulder beam 5 for support and connected to the roof 6; a steel tie bar 7 is arranged at the upper end of the first steel column 3 support to connect and fix the shoulder beam 5 and the first steel column 3 supports on both sides, and a working height is left below the steel tie bar 7.

[0026] In this embodiment, the roofs 6 of the two factory rooms 1 have no height difference. A set of longitudinal roof supports 8 is installed at the connection between the second steel columns 4 and the roof 6. These longitudinal roof supports 8 are located on either side of the two factory rooms 1. Furthermore, the crane beams 9 of the two factory rooms 1 are located at the same height, and the two sets of crane beams 9 share a brake system 10.

[0027] In the embodiment, the traditional lattice steel columns 13 arranged on both sides of the middle span 2 are replaced by "large lattice columns" with a larger limb distance, and the steel bars 7 are connected above the space of the middle span 2 which does not affect the process requirements. In this way, on the one hand, the support performance of the plant room 1 and the middle span 2 is not affected, and on the other hand, the amount of steel is greatly reduced under the same conditions. According to the calculation, the amount of steel used by each rigid frame is about 69.7t, and the single rigid frame foundation concrete needs 182.10m3.

[0028] In addition, as shown in Figure 3 When the plant room 1 has a certain height difference, the utility model embodiment two provides a process middle span 2 without crane's plant column arrangement structure, which comprises two plant rooms 1, the middle span 2 is arranged in the middle of the two plant rooms 1, the first steel column 3 support is arranged on both sides of the middle span 2, the shoulder beam 5 is arranged on the top of the first steel column 3 support, the second steel column 4 support is arranged on the shoulder beam 5 and connected with the roof 6, the steel bar 7 is arranged on the upper end of the first steel column 3 support and fixedly connected with the shoulder beam 5 and the first steel column 3 support on both sides, and the working height is left below the steel bar 7.

[0029] In the embodiment, the roof 6 of the two plant rooms 1 has a height difference, two groups of longitudinal roof supports 8 are arranged at the support connection between the second steel column 4 support and the roof 6, and the two groups of longitudinal roof supports 8 are respectively arranged at the support of the second steel column 4 of the two plant rooms 1. The shoulder beam 5 arranged on the top of the first steel column 3 support is two groups, one group is located on the top of the first steel column 3 support on the low side, and the other group is located on the top of the first steel column 3 support on the high side. The crane beam 9 of the two plant rooms 1 is located at different heights, and the two groups of crane beams 9 are respectively provided with corresponding brake systems 10. The brake system 10 is fixed on the corresponding shoulder beam 5 through the auxiliary truss 12. The gutter 11 is arranged on the roof of the high-side plant room 1.

[0030] According to the calculation, the amount of steel used by each rigid frame is about 73.4t under the condition of the embodiment two, and the single rigid frame foundation concrete needs 157.13m3.

[0031] Therefore, it can be seen that under the premise of ensuring the support performance of the plant room 1, the process middle span 2 without crane's plant column arrangement structure adopting the utility model structure saves the amount of steel and the amount of concrete compared with the traditional structure facade mode, and greatly saves the engineering cost.
