Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated beam manufacturing, and more specifically relates to a detachable and reusable prefabricated beam pedestal. Background Art

[0002] In the construction of contemporary bridge deck systems, more and more people choose to use precast beams. The beams are first cast and precast on the construction site, and then transported to the construction site for laying. After the production of precast beams is completed, the precast beams need to be maintained to facilitate their later use. In the process of precast beam maintenance, precast beam pedestals are needed to support and fix the precast beams to facilitate the maintenance of the precast beams.

[0003] At present, factory-based centralized prefabrication is often used for the prefabrication of highway bridge beams and slabs. Box beams are a type of prefabricated bridge beam structure that is hollow inside and has flanges on both sides of the upper part. It is named after the box-like shape. Concrete pedestals are the more commonly used prefabricated beam pedestals in beam and slab prefabrication. For the construction of commonly used concrete pedestals, it is first necessary to excavate and expand the foundation and carry out earth excavation. Both the end expansion foundation construction and the pedestal main foundation construction require concrete maintenance and waiting for the concrete strength, which is time-consuming. Moreover, when the concrete pedestal is used up, the concrete waste removed during site repair will pollute the environment, which not only wastes resources and pollutes the environment, but also brings inconvenience to subsequent construction. After the beam and slab prefabrication is completed, it needs to be chiseled out. However, the labor and machinery costs are increased during the chiseling process, and it is inconvenient to dismantle. Utility Model Content

[0037] A swivel 4 provided on the support column 2, and a connecting rod 5 fixedly provided on the swivel 4;

[0038] The bottom of the connecting rod 5 is respectively provided with two hinges, and both are connected with a movable rod 8, wherein the hinge close to one end of the support column 2 is connected and fixed by a mounting block 12 disposed on the top of a fixing plate 11 disposed on the support column 2;

[0039] The mounting blocks 12 are symmetrically arranged, and the movable rod 8 can be fixed on the mounting blocks 12 by arranging bolts;

[0040] The swivel 4, the connecting rod 5, and the movable rod 8 are all arranged on the support column 2 on one side connected to the X-shaped reinforcement frame 10;

[0041] On the support column 2 that is symmetrical on the other side of the X-shaped reinforcement frame 10, a fixing block 9 is provided at the same installation position as the swivel 4 on the support column 2, and the fixing block 9 is symmetrically arranged;

[0042] The fixing block 9 is provided with a mounting hole 14, and the mounting hole 14 is vertically through-set;

[0043] The outer side wall of one side of the fixing block 9 is concave;

[0044] The fixing plate 11 and the mounting block 12 are symmetrically arranged on all the support columns 2, and correspondingly, the same fixing plate 11 and mounting block 12 are arranged under the fixing block 9;

[0047] The utility model supports and bears the precast beams through the support units, and in order to make the precast beam pedestal detachable and capable of arbitrary assembly and splicing, and suitable for bearing precast beams of different specifications, the utility model completes the overall installation and disassembly by setting the connection units, and has a simple structure, which is also convenient for later maintenance and replacement. The amplitude adjustment during the splicing process is completed by setting the limit units, so that when the pedestal assembly is connected, it is more convenient and quick to limit and fix.

[0048] like Figure 3-5 As shown, in the embodiment of the utility model, a detachable and reusable prefabricated beam pedestal is provided. In the support unit, the base 3 is arranged in a cross shape, and the top frame 1, the support column 2 and the base 3 are fixedly connected. When in use, the reinforcement rod 13 passes through the support columns 2 on both sides, and the reinforcement rod 13 is locked and fixed by nuts; the X-shaped reinforcement frame 10 can be welded and fixed between the support columns 2, and the support column 2 for clamping the X-shaped reinforcement frame 10 can also be customized. The support unit needs to ensure the overall stability so as to carry the prefabricated beam;

[0049] After the installation of the connection unit is completed, in order to enable the pedestals to be spliced ​​with each other and increase the bearing area and load capacity; when one end of the movable rod 8 is fixed to the connecting rod 5 through a hinge connection, the movable rod 8 close to one end of the support column 2 is fixed to the mounting block 12 of the fixing plate 11 by bolts, so that the connecting rod 5 and the movable rod 8 are fixedly connected to the support column 2 through the mounting block 12 and the fixing plate 11;
