DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The object of the present invention is to provide a distribution beam connection structure to solve the problems existing in the above-mentioned prior art. The connection structure is stable and can withstand a large impact load.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention provides a distribution beam connection structure, including a distribution beam 1, a Bailey beam 2, and an upright support rod 3. The Bailey beam 2 is provided below the distribution beam 1, and an elastic support component is provided between the distribution beam 1 and the Bailey beam 2; the upright support rod 3 is arranged at the bottom of the Bailey beam 2, and the Bailey beam 2 is fixedly connected to the upright support rod 3 through a connecting piece; the connecting piece includes a buckling ring 901, an abutment plate 902 and a bolt. The buckling ring 901 is a rectangular frame structure as a whole, and an opening 904 is opened on one of the side walls. The buckling ring 901 is slidably sleeved on the flange plate of the distribution beam 1 through the rectangular cavity and the opening 904. A threaded hole is provided on the side wall of the buckling ring 901 opposite to the opening 904. The bolt 903 is connected in the threaded hole and fixedly abuts with the distribution beam 1. One end of the abutment plate 902 is connected to the end of the side wall where the threaded hole on the buckling ring 901 is located, and the other end is fixedly abutted with the flange at the top of the upright support rod 3.

[0029] When the buckle ring 901 is slidably mounted on the Bailey beam 2, the buckle ring 901 can be tightened and fixed on the Bailey beam by bolts 903, and the abutment plate 902 can be pressed on the flange plate of the upright support rod 3, so as to realize the connection and fixation between the Bailey beam 2 and the upright support rod 3; when disassembling, it is only necessary to loosen the bolts 903, which is convenient and quick. In order to increase the compactness of the connection between the buckle member 9 and the Bailey beam and the upright support rod 3, the length of the long side of the rectangular cavity in the middle of the buckle ring 901 is equivalent to the width of the flange plate of the Bailey beam, and the width is between the minimum thickness and the maximum thickness of the flange plate of the Bailey beam, and the width of the opening 904 on the buckle ring 901 is equivalent to the belly thickness of the Bailey beam. Since the cross section of the flange plate of the I-beam is usually not a regular rectangle, but a structure that gradually thickens from the edge to the web, the minimum thickness and the sum of the flange plates of the Bailey beam 2 refer to the sum of the thickness of the edges of the two flange plates, and the maximum thickness and the sum refer to the sum of the thickness of the two flange plates near the web. The width of the rectangular cavity in the middle of the buckle ring 901 is between the sum of the minimum thickness and the maximum thickness of the flange plate of the Bailey beam 2 to ensure that the abutment plate 902 can make the flange plates of the Bailey beam 2 fit closely together through deformation, thereby increasing the friction between the two and improving the reliability of the connection. The length of the abutment plate 902 does not exceed the distance between the side of the flange plate of the upright support rod 3 and its web. In this way, when the buckle ring 901 is slidably set on the Bailey beam 2, when its end contacts the edge of the flange plate of the upright support rod 3, the abutment plate 902 will not contact the web of the upright support rod 3, so that the buckle ring 901 can be used to limit the Bailey beam 2 in its length direction. When making the connecting buckle 9, the buckle ring 901 and the abutment plate 902 can be set as an integral structure, that is, a T-shaped steel plate is used to bend one side to form the buckle ring 901, and the other side is used as the abutment plate 902. In order to prevent the connecting fastener 9 from being deformed after long-term use, it is best to use threaded steel to make it.

[0030] In one embodiment, a clamping buckle is provided on the side wall of the upright support rod 3, and the clamping buckle is connected to an anchor rod 16, and an anchor tip 18 is provided at one end of the anchor rod 16; disc-shaped anchor blades 19 are staggered at the lower part of the anchor rod 16, so that the anchor rod 16 is inserted below the ground, which can provide a stable connection assistance for the upright support rod 3, so that the overall load-bearing capacity is better. The clamping buckle of this embodiment is a clamping device 17, which includes two arc-shaped clamping plates 20 with the same structure, and the two ends of the arc-shaped clamping plates 20 are respectively provided with extension plates 21 with a middle opening, and bolts are installed at the opening of the extension plate 21; a perforated flange plate 22 with a hole is provided on the outer wall in the middle of the arc-shaped clamping plate 20, and the perforated flange plate 22 is fixedly connected to the anchor rod 16.

[0031] In order to make the overall structure of the present invention more stable, the distribution beam 1 structure is designed to include an upper distribution beam 10, a plurality of connection reinforcements and a plurality of lower distribution beams 11. The lower distribution beams 11 are arranged in parallel and spaced apart. The upper distribution beam 10 is fixedly arranged on the lower distribution beam 11. The upper distribution beam 10 and the lower distribution beam 11 are arranged vertically. One end of the first bracing rod 12 is fixedly connected to the top of the side of the upper distribution beam 10, and the other end is fixedly connected to the end of the top surface of the lower distribution beam 11. One end of the second bracing rod 15 is fixedly connected to the bottom of the side of the upper distribution beam 10, and the other end is fixedly connected to the middle of the first bracing rod 12. The first bracing rod 12 and the second bracing rod 15 are fixedly connected to the upper distribution beam 10 and the lower distribution beam 11 through the segment plate 14. In addition, the segment plate 14 is fixedly welded to the middle of the first bracing rod 12, and the first bracing rod 12 and the second bracing rod 15 are fixedly connected through the segment plate 14. The lower distribution beam 11 is an I-beam. In order to strengthen the lower distribution beam 11 , reinforcing plates 13 are provided at the corresponding positions of the lower distribution beam 11 and the upper distribution beam 10 , that is, at both sides of the middle of the web of the lower distribution beam 11 .

[0032] In a preferred embodiment, the elastic support assembly includes a horizontally arranged buffer layer 5 and a first support 6 and a second support 7 vertically fixedly connected to the Bailey beam 2. Two second supports 7 are provided, and the two second supports 7 are symmetrically arranged on both sides of the first support 6. The first support 6 and the two second supports 7 are respectively abutted against the lower surface of the distribution beam 1, and a flexible buffer 8 is sleeved on the second support 7; the upper surface of the buffer layer 5 is abutted against the lower surface of the distribution beam 1, and the lower surface of the buffer layer 5 is fixedly connected to the top surface of the flexible buffer 8. When the upper surface of the distribution beam 1 is subjected to heavy pressure, the elastic support assembly on the lower surface of the distribution beam 1 will apply a reaction support force to the distribution beam 1 under the action of elastic force. At the same time, the elastic support assembly is arranged on the Bailey beam 2, and the Bailey beam 2 and the elastic support assembly together form a stable reaction force support structure, so that the distribution beam 1 of the bridge will not cause the bridge surface to crack or collapse due to high pressure.

[0033] In a specific embodiment, a plurality of inclined connecting plates 4 are bonded between the distribution beam 1 and the Bailey beam 2, and the plurality of inclined connecting plates 4 are arranged on both sides of the elastic support assembly. Sometimes, there will be oblique cracks on the bridge, and the problem of stress dispersion of the bridge can be solved by bonding the inclined connecting plates 4, which is simple and easy to operate. When the length of the inclined connecting plates 4 cannot meet the actual needs, the inclined connecting plates 4 can be replaced with fiber strips.

[0034] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
