[0019] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement it according to the description.

[0020] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] like Figures 1 to 5 As shown, the utility model provides a temporary support frame for high-altitude docking of steel beams / steel trusses, including a plurality of standard sections 1 and two non-standard sections 2 which are connected in sequence as one, the two non-standard sections 2 are respectively located at the top and the bottom of the support frame, the standard sections 1 are connected by sleeves 7 and bolts 9, a plurality of connecting plates 8 are arranged on the two non-standard sections 2, bolt holes are arranged on the corresponding positions of the sleeves 7 of the adjacent standard sections 1, and the non-standard sections 2 are connected to the standard sections 1 by inserting bolts 9 in the corresponding sleeves 7 and bolt holes.

[0022] The bottom non-standard section 2 of the support frame includes a bottom ring beam 3, and the connecting plate 8 is arranged on the web of the bottom ring beam 3. The top standard section 1 of the support frame includes a top ring beam 4, a top support ring beam 5, and a plurality of supporting columns 6 connected between the top ring beam 4 and the top support ring beam 5, and the connecting plate 8 is arranged on the web of the top ring beam 4. The bottom non-standard section 2 is welded and fixed to the ground by embedded parts and anchor bolts 10 to fix the support frame. A 20mm thick (or required thickness) steel plate is provided on the upper part of the embedded parts to cushion the bottom ring beam to offset the deflection of the bottom steel beam so that the steel beam will not contact the ground or floor when deflecting downward.

[0023] The prior art is to set a self-made rectangular tube or H-shaped steel vertical support from a reliable support point below the high-altitude docking point. The present application uses a standard section 1 and a non-standard section 2 in combination. The standard section 1 is a fixed-height standard section 1 commonly seen in the market, such as: tower crane standard section 1, 3 meters / section, etc. The height h from the reliable support point directly below the high-altitude docking point to the top support point of the lower chord of the steel beam / steel truss is divided by the height of the standard section 1, and the remainder is made up by the self-made non-standard section 2. Because the standard section 1 is rented in the market, the connection method is fixed and connected by bolts 9 and sleeves 7. The non-standard section 2 is made of H-shaped steel or rectangular tubes and cannot be welded to the standard section 1, so it is necessary to design a node on the self-made non-standard section 2, that is, to set a connecting plate 8 with corresponding openings to match the connection of the standard section 1.

[0024] The connection node between the standard section 1 and the non-standard section 2 is mainly completed on the non-standard section 2. A connection plate 8 is welded on the web of the top ring beam 4 or the bottom ring beam 3 of the non-standard section 2. The position of the connection plate 8 matches the position of the sleeve 7 on the standard section 1 one by one. Bolts 9 of corresponding length are purchased from the market, and the standard section 1 and the non-standard section 2 are reliably connected by bolts 9 according to the connection method of the standard section 1.

[0025] The length and steel usage of the non-standard section 2 in this application are small, less than the length of a standard section 1. When the support height is large, this application will greatly reduce the economic burden of temporary measures in practical applications. This application has a total of 3 components: standard section 1, non-standard section 2 and corresponding connection nodes. Figure 1 and Figure 2 As shown, the support frame of the present application is composed of non-standard sections 2 at the top / bottom and standard sections 1 in the middle; the height of the support frame is the height of non-standard section 2 + the height of standard section 1 * N. When the vertical support height is larger, the proportion of non-standard section 2 is smaller, and the economic benefit is more obvious. Figures 3 to 5 As shown, the standard section 1 and the non-standard section 2 are connected by bolts 9, the connecting plate 8 is welded to the web of the ring beam of the non-standard section 2, and holes are opened on the connecting plate 8 to prepare for the connection of the sleeve 7+bolt 9. The number and position of the connecting plates 8 are based on the position of the column foot sleeve 7 of the standard section 1, and the number and position are corresponding. The connection node of the present application can ensure that no adjustment is made to the standard section 1, and it can be used as it is rented, which can ensure the integrity and operability of the non-standard section 2, and also ensure the reliable connection between the standard section 1 and the non-standard section 2.

[0026] The bottom ring beam 3 and the top ring beam 4 of the multiple support frames in the same horizontal direction are connected to form a whole so that the multiple support frames are connected as a whole. The ring beams are all made of H-shaped steel or rectangular tubes. The steel beams corresponding to the bottom ring beam 3 and the top ring beam 4 in the same horizontal direction are an overall closed-loop steel beam structure. The multiple support frames can be connected as a whole to form an overall support structure.

[0027] It can be understood that the utility model is described through some implementation cases, and those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the utility model. Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme, and it can be fully applied to various fields suitable for the utility model. For those familiar with the art, other modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the utility model is not limited to specific details and the illustrations shown and described here.
