[0002] As the traffic volume increases, the existing traffic design does not meet the traffic capacity, causing serious congestion on the road. To convert the beam bridge system on the original road section, the original bridge must be demolished. The safety and stability of the bridge structure must be ensured during the demolition process. At the same time, under the condition that the original main line is open to traffic, the efficiency of bridge demolition must be ensured to alleviate the traffic safety and traffic pressure on the road section. The bridge demolition process involves the rental costs of mechanical equipment, support materials, etc. In order to control the construction cost, the rental time of equipment and materials must be minimized.

[0003] When installing the existing bridge demolition construction support, the installation points are usually measured and marked first; the steel pipe columns are transported to the construction site by a flatbed trailer, and the steel pipe columns are assembled into 2m*2m unit supports, and then the support is placed at the marked position by a forklift; the top crossbeam of the support is installed and welded and fixed using lifting equipment; finally, the support is lifted using mechanical equipment so that the crossbeam of the support is in close contact with the bottom end of the bridge block, the adjustment section is installed at the bottom end of the support column, and an iron sheet is placed at the upper end of the crossbeam of the support.

[0004] However, the bracket needs to be assembled on-site, which takes a long time. In addition, the distance between the lower end of the bridge and the ground is different, which means that not only the lower end of the bracket needs to fix adjustment sections of different lengths, but also the upper end needs to be raised. Therefore, the bracket assembly time is long, which prolongs the construction process and affects the efficiency of bridge demolition. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0025] The features and performance of the present application are further described in detail below in conjunction with the embodiments.

[0026] like Figure 1-Figure 4 As shown, the utility model provides a bridge demolition construction support that is easy to install, including multiple support units, the support unit includes four columns 1, a crossbeam 2 and a connecting frame 3, two adjacent columns are connected by the connecting frame to form a stable rectangular frame structure, there are two crossbeams, which are symmetrically arranged on the top of the two columns on the corresponding sides, and a support plate assembly with adjustable height is provided on the crossbeam, and the bottom end of the column is connected to an adjustment column 4.

[0027] The support plate assembly includes a support plate body 5, a pad 6 and an anti-slip rod 7. The support plate body is fixed to the top surface of the beam by the anti-slip rod, and the pad is arranged between the beam and the support plate body. The pad thickness varies, so that the spacing between the support plate body and the beam is adjustable. By arranging pads of different thicknesses, the support requirements of the bridge demolition construction support are met, the support strength is ensured, and the installation time of the bridge demolition construction support is shortened.

[0028] The anti-drop rod is a rod with a stopper at the bottom, and the top passes through the top surface of the beam and is connected to the support plate. The anti-drop rod can be adjusted up and down with the thickness of the pad, and the pad is positioned by the anti-drop rod to improve the installation stability. The length of the anti-drop rod is less than the height of the beam.

[0029] A plurality of groups of connection blocks 8 are arranged at intervals along the axial direction of the column, and each group of connection blocks is evenly spaced along the circumference of the same cross section of the column. A connection hole 9 is arranged on the connection block. A first connection plate 10 is respectively arranged at the top and bottom of the column, and a second connection plate 11 is respectively arranged at the top and bottom of the adjustment column. The first connection plate is aligned with the second connection plate and fastened by bolt connection. By fixing adjustment columns of different lengths under the column, the construction requirements of the bracket are met, and the stability of the support unit can be ensured.

[0030] like Figure 5 As shown, the connection frame is a rectangular frame structure, and screw holes 12 are provided at the four corners, corresponding to the connection holes, and are fastened by bolts.

[0031] The top and bottom sides of the connection frame are respectively provided with screw holes and limit rods 13 screwed with the screw holes. The limit rod is a U-shaped bent rod with an external thread on one end configured with the screw hole and the other end buckled at the connection between the connection frame and the connection block.

[0032] The limit rod can be rotated relative to the connecting frame. By rotating the limit rod, the position of the limit rod relative to the connecting frame is adjusted, so that when the connecting frame is fixed between the columns, the limit rod can be used to hook the connecting frame on the connecting block for positioning, thereby avoiding displacement during the connection process between the connecting block and the connecting frame, and improving the connection efficiency of the bridge demolition construction support.

[0033] Arc-shaped positioning plates 14 are provided on both sides of the position of the cross beam and the first connecting plate, and the arc-shaped positioning plates and the first connecting plate are fastened by bolt connection.

[0034] When using the bridge to dismantle the construction support, first place the column horizontally, then place the connecting frame between two adjacent columns, adjust the position of the limiting rod relative to the connecting frame by rotating the limiting rod, and when the connection hole corresponds to the position of the screw hole, hook the limiting rod on the connecting block to complete the positioning of the connecting frame and the column, and then insert the bolts into the connecting holes and the screw holes in turn to complete the fixation of the connecting frame and the column until the columns form a rectangular structure, and then stand up the unit support formed by the columns, use the lifting device to lift the beam above the column, and after the arc-shaped positioning plate overlaps with the first support plate at the upper end of the column, use bolts to connect and stabilize the beam and the column, and then use the lifting device Lift the beam and the column to make the bottom of the column at the same level, and then bolt the adjustment column of the required length to the first support plate at the lower end of the column through the second support plate as needed to complete the support adjustment processing of the bottom of the column. The bridge demolition construction bracket is supported by the adjustment column below. At this time, the pad is placed between the support plate and the beam to allow the support plate to be tightly supported under the bridge. The support plate is raised and lowered by the limit of the anti-drop rod to allow the pad to be smoothly inserted between the support plate and the beam, completing the efficient assembly and connection processing of the bridge demolition construction bracket. Compared with the traditional connection method, it has the advantages of accurate positioning and fast connection, thereby completing a series of work.
