the bracket assembly 3 further comprises an additional beam 3.2 arranged on the gantry assembly 1, and the length direction of the additional beam 3.2 is parallel to the telescopic direction of the telescopic mechanism 4; the first bracket 3.1a and the second bracket 3.1b are movably connected with the additional beam 3.2 through sliding seats; in this embodiment, in order to ensure the stability of the additional beam 3.2 in guiding the first bracket 3.1a and the second bracket 3.1b, two additional beams 3.2 are arranged in parallel on the gantry assembly 1, and each additional beam 3.2 is provided with two sliding seats, as shown in fig. 3; the two carriages are intended to be connected to a first carriage 3.1a and a second carriage 3.1b, respectively.
In this embodiment, the additional beam 3.2 is a high-strength rectangular steel pipe, and the sliding base is provided with a limiting space for accommodating the additional beam 3.2, so as to prevent the first formwork 2.1a and the second formwork 2.1b from tipping in the sliding process. In this embodiment, the sliding seat is provided with a U-shaped limiting space for accommodating the additional beam 3.2, the first bracket 3.1a or the second bracket 3.1b is installed at the top of the sliding seat, and the additional beam 3.2 is located in the closed space formed by the sliding seat and the first bracket 3.1a or the second bracket 3.1b, so that the first template 2.1a and the second template 2.1b are prevented from tipping in the sliding process due to the limiting function of the sliding seat.
The sliding seat comprises a limiting block 3.3.1 and a connecting piece, as shown in figure 4; stopper 3.3.1 top with first bracket 3.1a or second bracket 3.1b is connected, and stopper 3.3.1 bottom is connected with the connecting piece, two stopper 3.3.1 is located the connecting piece both sides, stopper 3.3.1 with the connecting piece combination forms and is used for holding additional crossbeam 3.2's spacing space.
In this embodiment, the connecting element is a connecting block (i.e. connecting element one 3.3.2a in fig. 4) provided with a sliding plate, which is located on the contact surface of the connecting element and the additional beam 3.2. The sliding plate is installed through bolts, and the sliding plate in the embodiment is a polytetrafluoroethylene sliding plate, so that the frictional resistance between the first sliding seat 3.3a and the additional cross beam 3.2 can be reduced.
With reference to fig. 1 to 3, the first bracket 3.1a and the second bracket 3.1b each comprise a bracket cross beam 3.1.1, a bracket longitudinal beam 3.1.2 and a support bar 3.1.3; the bracket beam 3.1.1 is connected to the gantry assembly 1 through the telescopic mechanism 4; the bracket longitudinal beam 3.1.2 is connected with a plurality of sliding seats positioned on the same side of the portal assembly 1, and the length direction of the bracket longitudinal beam 3.1.2 is vertical to the length direction of the additional cross beam 3.2; the support rods 3.1.3 are arranged on the bracket longitudinal beams 3.1.2 and are used for supporting the template assembly 2.
