Description

Technical fields:

[0001] This utility model relates to the field of pedestal technology, specifically to a precast beam assembly pedestal. Background technology:

[0002] In precast beam construction, concrete foundations are typically used to meet the load-bearing requirements of the precast beams. Connecting reinforcing bars are pre-embedded during concrete pouring. The precast beam support is then welded on-site according to the beam's dimensions. The support frame is welded first, and steel plates are laid on top to form the support. On-site processing is time-consuming, the structural dimensions are not precise enough, welding shrinkage deformation is significant, and the panels are prone to warping. After use, they cannot be reused after cutting and dismantling. Sometimes, the support is directly poured with concrete on-site, but this method offers no value for reuse. Utility Model Content:

[0003] Therefore, this utility model provides a precast beam assembly platform to overcome the problems of the prior art.

[0004] This utility model is implemented by the following technical solution:

[0005] A precast beam assembly platform includes a mid-span standard segment and a support-bearing segment. The length of the mid-span standard segment is greater than the length of the support-bearing segment. The two are assembled to meet the needs of precast beams with different spans. Both the mid-span standard segment and the support-bearing segment include transversely laid legs, a longitudinally fixed distribution beam at the top of the legs, and a steel plate panel fixed at the top of the distribution beam. The spacing between adjacent legs of the support-bearing segment is smaller than the spacing between adjacent legs of the mid-span standard segment. The steel plate panel extends beyond the distribution beam on both sides, and steel strips are welded to the bottom of its sides to form a continuous groove. A sealing strip is embedded in the continuous groove to stop grouting. Circular holes for integrating and laying cables and sprinkler pipes are opened at the bottom of the legs. The bottoms of the mid-span standard segment and the support-bearing segment are connected to the foundation surface through detachable fasteners.

[0006] Preferably, the support leg is made of I-beam, and stiffening ribs are welded to both sides of the I-beam to enhance the structural strength.

[0007] Preferably, the distribution beam is a channel steel and is evenly distributed along the top of the support leg.

[0008] Preferably, the detachable fasteners include expansion bolts or pre-embedded welded steel bars.

[0009] Preferably, the sealing strip is adapted to the size of the elongated groove to form a sealing and grout-stopping structure.

[0010] The advantages of this utility model are: by dividing the pedestal into standard mid-span segments and load-bearing segments, and adopting a factory prefabrication and on-site assembly mode, the cumbersome procedures of traditional on-site welding or casting of pedestals are avoided, the installation time is shortened compared with traditional processes, the production progress of precast beams is significantly accelerated, and by combining different numbers of segments, it can adapt to the needs of multi-span precast beams. Moreover, the segments can be disassembled and reused, and the materials can be reused, resulting in a lower overall cost compared with traditional concrete pedestals. Attached image description:

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, a precast beam assembly platform includes a mid-span standard segment 1 and a support-bearing segment 2. The lengths of the mid-span standard segment 1 and the support-bearing segment 2 can be set to a certain length according to requirements, while the length of the support-bearing segment 2 should be less than the length of the mid-span standard segment 1.

[0018] For example, the length of the standard mid-span segment 1 can be set to 5m, and the length of the support-bearing segment 2 can be set to 3m. The two can be assembled in different quantities to meet the requirements of precast beams with different spans. If a 30m precast beam is needed, 5 standard mid-span segments 1 + 2 support-bearing segments 2 can be used to prepare a precast beam with a total length of 31.6m.

[0019] After the assembly is completed section by section, the bottom of the standard mid-span segment 1 and the support-bearing segment 2 can be fixed to the foundation surface by expansion bolts or pre-embedded steel bars.

[0020] The mid-span standard segment 1 includes multiple transversely laid support legs 3, longitudinally fixed distribution beams 4 laid on top of the support legs 3, and steel plate panels 5 fixed on top of the distribution beams 4.

[0021] The spacing between adjacent support legs 3 is set at a certain distance. Support legs 3 are made of I-beams, and multiple stiffening ribs are welded at equal intervals on both sides of the I-beams.

[0022] The steel plate panel 5 extends beyond the distribution beam 4 on both sides. The distribution beam 4 is made of channel steel, and steel strips 6 are welded to the bottom of the side of the steel plate panel 5 to form a continuous groove. A sealing strip 7 is fitted and embedded in the continuous groove. The sealing strip 7 can be used as a grout stop strip.

[0023] The structure of the support-bearing segment 2 is similar to that of the mid-span standard segment 1. The spacing between adjacent legs 3 of the support-bearing segment 2 is smaller than that between adjacent legs 3 of the mid-span standard segment 1 to enhance the bearing capacity and meet the strength requirements under concentrated loads at both ends of the precast beam.

[0024] The bottom of the support leg 3 has a circular hole of a certain diameter, which can be used to lay cables and sprinkler pipe facilities. The cable laying provides power during the precast beam process on the pedestal, and the sprinkler pipe facilities provide curing water for the precast beam.

[0025] After the basic layout, the sections are assembled one by one. The bottom of the support leg 3 of the standard segment 1 in the middle of the span and the support leg 3 of the load-bearing segment 2 are directly fixed by expansion bolts or pre-embedded steel bars.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
