In the node of the bailey beam structure, as shown in fig. 18 and 19, when there are more support rods connected to the same section of the upper chord 61 by the distribution beam 7, such as the section I and the section J, the bottom of the upper chord 61 at the section I is the intersection of two upper diagonal support rods 64 with different arrangement directions, at this time, the telescopic connecting rod 4 is used, the section J is the intersection of the head and the tail of two sections of truss units, and the section has two vertical support rods 63 arranged side by side, and it can be seen that a section steel is additionally arranged on the upper part of the upper chord 61 of the bailey beam 6, a common connecting fixer cannot be used for fixing and reinforcing, while the fixing rod 2 and the connecting rod 4 in this embodiment can be both telescopic, the lengths of the straight rod section 21 and the connecting rod 4 can be adjusted, so that the first straight rod section 21a and the second straight rod section 21b are relatively extended and fixed, and simultaneously, the first connecting rod 41 and the second connecting rod 42 are relatively extended and fixed, so that the novel Bailey beam and distribution beam connecting and fixing device can fix and reinforce the distribution beam 7 and the Bailey beam 6, and further ensure the stability and the safety of the bracket 8, and when the first connecting rod 41 and the second connecting rod 42 are fixed, the later stated double-channel type hoop 12 is preferably used for fixing.

Thirdly, the locking hole 101 on the compressing part 1 of this application is the bar hole for correspond the distance of adjusting two dead levers 2 that arrange side by side in novel bailey roof beam and the distribution beam connection fixer, when connecting rod 4 is retractable structure, after adjusting the overlap joint length of head rod 41 and second connecting rod 42, will compress tightly a 1 and fix on dead lever 2 through anchor assembly (adopt the nut to screw up on connecting thread 211).

The novel connecting and fixing device for the Bailey beam and the distribution beam has the advantages of wide application range and multiple application occasions.

In addition, this embodiment has still provided two kinds of connection clamp structures, as follows respectively:

firstly, in order to fix the pressing member 1 and the fixing rod 2 more firmly, the stress condition is better, and the pressing member 1 is effectively protected from being damaged, the preferred embodiment is to use round steel and steel pipe structure as the pressing member 1, when the pressing member 1 adopts round bar structure, the pressing member 1 is preferably fixed on the straight rod section 21 of the fixing rod 1 by using the double fixed type hoop 11 of the embodiment, and the two are tightly fixed by using the double fixed mode, specifically, as shown in fig. 13-15, the double fixed type hoop 11 comprises a bending rod member 111 with a first hoop bend 111a, and further comprises a locking piece 112 with a second tile type hoop 112a, the bending rod member 111 is further provided with a second hoop bend 111b, the second hoop bend 111b is formed by bending the bending rod member 111 at two ends of the first hoop bend 111a again, the locking piece 112 is connected to two second hoop bends 111b ends of the bending rod member 111 through a nut 9, make first staple bolt elbow 111a and second tile formula staple bolt 112a are in on same face of cylinder to adopt two fixed clamps 11 will compress tightly a 1 when fixing at straight-bar section 21, first staple bolt elbow 111a, second staple bolt elbow 111b and second tile formula staple bolt department 112a set up the rubber cushion, improve and compress tightly the friction between 1 and the dead lever 2, and then improve the firm in connection degree, compress tightly 1 and dead lever 2 and also can adopt current pipe strap to fix. When the bailey beam and the distribution beam move under the action of external force, the acting force applied to the fixing rod 2 or the pressing piece 1 can be converted into larger locking force through the double-fixed hoop 11, so that the straight rod section 21 and the pressing piece 1 are connected more firmly;

secondly, when the above-mentioned connecting rod 4 adopts a telescopic structure, it includes a first connecting rod 41 and a second connecting rod 42 arranged side by side, and it can be fixed by a common pipe clamp, and it can also be fixed by a binding band, the preferred embodiment of this embodiment is to fix by a dual channel type clamp 12, as shown in fig. 16 and 17, the dual channel type clamp 12 includes two clamp structures, and fixes the first connecting rod 41 and the second connecting rod 42 at the same time, specifically, the dual channel type clamp 12 includes a locking rod 121 and two single type buckles 122, the two single type buckles 122 are installed on the locking rod 12 side by side, each single type buckle 122 includes two hinged clamp sheets 122a, one end of the two clamp sheets 122 is hinged, the other end is installed on the locking rod 121, and is screwed and locked by nuts 9 on both sides, the two clamp sheets 122a clamp the connecting rod 4 tightly by screwing the nuts 9, and two single buckles 122 are arranged side by side, guarantee respectively to press from both sides can not slide between the tight fixed head rod 41 of clamp and the second connecting rod 42, and then improve the whole fastness that novel bailey roof beam and distribution beam are connected the fixer, are adopting. This double-channel formula clamp 12 also preferably is used for dead lever 2 of this embodiment to be retractable structural style in, when adopting two straightway overlap joint structures, can guarantee the sound construction through the double-channel formula clamp 12 of this embodiment.

The foregoing is merely a detailed description of specific embodiments of the utility model and is not intended to limit the utility model. Various alterations, modifications and improvements will occur to those skilled in the art without departing from the spirit and scope of the utility model.
