The following describes a groined support frame and a foundation pit supporting structure with the same in detail with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.

Referring to fig. 1 to 3, the present application provides a cross-shaped support frame. The # -shaped support frame comprises a vertical column 1, a bracket beam 3 connected to the vertical column 1 and a cross beam 4 connected to the bracket beam 3. The upright column 1 comprises a first upright column 11 and a second upright column 12 which are vertically arranged at intervals, a first support seat part 21 is arranged on the first upright column 11, and a second support seat part 22 is arranged on the second upright column 12. The bracket beam 3 comprises a first bracket beam 31 provided on the first bracket member 21 and a second bracket beam 32 provided on the second bracket member 22, the first bracket beam 31 and the second bracket beam 32 being parallel. The cross beam 4 comprises a first beam 41 and a second beam 42, which are spanned on the first bracket beam 31 and the second bracket beam 32. The first cross beam 41 and the second cross beam 42 are symmetrically located at two sides of a connecting line of the first upright post 11 and the second upright post 12, and the first bracket beam 31, the second bracket beam 32, the first cross beam 41 and the second cross beam 42 enclose a # -shape.

The utility model provides a groined type support frame is through setting up stand 1 and erectting the groined type that first bracket beam 31, second bracket beam 32 and first crossbeam 41, second crossbeam 42 on the stand 1 enclose can strengthen the stability of support and not too much occupy the foundation ditch space, does benefit to the construction operation of machines such as machineshop car.

As shown in fig. 1 to fig. 3, the upright 1 is an H-shaped steel upright, and the seat member 2 is fixed on the side surface of the upright 1 by bolts. Specifically, the main column 1 includes a first column 11 and a second column 12, the seat member 2 includes a first seat member 21 and a second seat member 22, the first seat member 21 is disposed on a side surface of the first column 11 facing the second column 12, and the second seat member 22 is disposed on a side surface of the second column 12 facing the first column 11. That is, the first and second housing members 21 and 22 are disposed to face each other. Each tray spare 2 all includes two face that are the right angle, and one of them face is used for fixing with stand 1 through the bolt, and another face is used for fixing with bracket roof beam 3 through the bolt. In order to increase the strength of the bracket member 2, the bracket member 2 further has a reinforcing rib connecting the two plate surfaces at right angles. In the present embodiment, the bracket member 2 and the pillar 1, the bracket beam 3 and the bracket member 2, and the bracket beam 3 and the cross beam 4 are all connected by bolts.

In this embodiment, each of the seat members 2 is provided with at least one set of bolt holes, and the set of bolt holes includes a circular hole 201 and an elongated hole 202. The combination of a set of bolt holes including a circular hole 201 and an elongated hole 202 avoids the problem of misalignment of bolt holes and the inability of bolts to pass through due to misalignment of bolt holes on the bracket member 2 and the bracket beam 3. The structure of the bolt holes in the present embodiment aligns the bracket beam 3 with the circular holes 201 of the bracket 2 when assembling, and the elongated holes 202 have a certain length, so that the bolt holes of the bracket beam 3 corresponding to the elongated holes have a certain positional deviation, and the bolt can be smoothly passed through and locked. In this embodiment, two sets of bolt holes are provided on each of the seat members 3, and in other embodiments, the number of the bolt holes may be three or more.

In this embodiment, each of the bracket beams 3 and each of the cross beams 4 are each a complete, non-spliced H-section steel. The bracket beam 3 and the cross beam 4 adopt complete and non-spliced H-shaped steel to ensure the strength of the H-shaped steel, and the risk of unreliable whole supporting system caused by poor connection quality at the joint of a splicing structure is avoided. Of course, in the case that the span length of the beam 4 needs to be enlarged, the beam 4 may also be formed by splicing two or more H-shaped steels. At this moment, in order to guarantee the structural strength of two or many H shaped steel concatenation departments, all set up the reinforcing plate in its concatenation department to the flange board and the web department of H shaped steel. The specific splicing mode of the H-shaped steel can be set by the prior art, and is not described again here.

Referring to fig. 4, the present application further provides a foundation pit supporting structure. The foundation pit supporting structure comprises a plurality of supporting beams 5 and the # -shaped supporting frame according to any one of the technical schemes. The plurality of support beams 5 are erected on a first cross beam 41 and a second cross beam 42 of the cross-shaped support frame. In the embodiment shown in fig. 4, an intermediate pressing member 6 is provided between the plurality of support beams 5. The projection of the intermediate pressing member 6 on the horizontal plane is at least partially located within the projection range of the cross-shape defined by the first and second bracket beams 31 and 32 and the first and second beams 41 and 42 on the horizontal plane. In other words, the cross-shaped support frame is disposed at a position where the support beam 5 has the intermediate pressing member 6. Because of set up in the supporting beam 5 middle pressure parts 6 makes weight increase, adopt the # -shaped support frame to support here, can strengthen and support intensity, need not to increase the quantity of stand 1 moreover, therefore can not too much occupy the foundation ditch space, can do benefit to machines such as machineshop car and pass through and the construction operation. Preferably, the top surface of the support beam 5 is provided with a long cover plate which connects the two support beams 5 in butt joint and an intermediate pressing member 6 between the two support beams 5 in butt joint. The long cover plate can strengthen the connection of the butted support beams 5 and the intermediate pressurizing pieces 6 between the butted support beams, and the reliability of the connection is enhanced.

It can be known from the above description that the groined support frame that this application provided and have this groined support frame through setting up stand 1 and erectting the groined font that first bracket roof beam 31, second bracket roof beam 32 and first crossbeam 41, second crossbeam 42 on the stand 1 enclose can strengthen the stability of support and do not occupy the foundation ditch space, do benefit to the construction operation.
