Abstract

The utility model discloses a tubular pile foundation beam storage pedestal shared by multiple beam types used in a precast beam field. The pile foundation beam storage pedestal shared by multiple beam types is of a two-supporting-point beam storage structure in the transverse direction; a plurality of tubular piles are arranged at the foundation of each beam storage supporting point; an inverted T-shaped bearing platform (2) is arranged on each tubular pile (1); a supporting seat plate (3) is transversely placed on the bearing platform (2); a precast beam (4) is placed on the upper surface of the supporting seat plate (3). According to the pile foundation beam storage pedestal shared by multiple beam types, the technical problems that the beams are cast and erected in an intertwined order and the beam storage time for a single beam type is short because of various of beam types in the precast beam field are successfully solved, and the beam storage place and the investment cost of the beam storage pedestal are effectively reduced.

Description

A kind of many beams type shares pipe pile foundation and deposits beam pedestal

Technical field

The utility model relates to the shared pipe pile foundation of a kind of many beams type adopting in precast beam field and deposits beam pedestal.

Background technology

Beam abutment design is deposited in precast beam field, and conventional method is deposited under beam fulcrum one or more stake is set for each, and beam body weight directly vertically passes to bottom pile foundation.General precast beam field, the Prefabricated bar type of bearing is fewer, and the beam pedestal of depositing of every kind of beam type is all independent design.When the Prefabricated bar type that precast beam field is born more, it is inconsistent that various beam types are deposited beam fulcrum horizontal spacing, and it is interlaced to make the order of setting a roof beam in place, and single beam type is deposited the beam time in short-term, adopt conventional method to increase and deposit beam pedestal quantity, increase beam field land area, cost is higher.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of many beams type adopting in precast beam field to share pipe pile foundation and deposit beam pedestal, to adapt in precast beam field due to the more demand of beam type, overcome depositing that conventional method exists beam pedestal quantity be many, floor space greatly, the deficiency of high in cost of production.

The utility model is by the following technical solutions: laterally adopt two fulcrums to deposit girder construction, each deposits beam fulcrum place basis instrument is many root canal piles, and inverted T shape cushion cap is set on pile tube, laterally places support plate on cushion cap, places precast beam above support plate.

Each cushion cap of depositing under beam fulcrum place support plate is absolute construction.

Support plate is packaged type; According to the size of placed precast beam, move.Every precast beam is placed respectively 2 support plates under two terminations, and each support plate separately correspondence is placed on independently on cushion cap.

Pipe pile top embeds composition rigid structures in cushion cap.

Cushion cap laterally adopts inverted T-shaped cross section along pedestal, and bottom is wider to meet the requirement of many root canal piles pile spacing, and top is narrower to reserve the space of before erection of precast beams, permanent bearing being installed.

The utility model has successfully solved in precast beam field because beam type is more, and the system order of setting a roof beam in place is interlaced, and single beam type is deposited short technical barrier of beam time, has effectively saved and deposited beam place, deposited beam pedestal cost investment.

The specific embodiment

With reference to accompanying drawing 1,2,3,4, the utility model provides a kind of many beams type adopting in precast beam field to share pipe pile foundation and deposits beam pedestal, laterally adopt two fulcrums to deposit girder construction, each deposits beam fulcrum place basis instrument is many root canal piles 1, inverted T shape cushion cap 2 is set on pile tube 1, on cushion cap 2, laterally place support plate 3, support plate 3 is placed precast beam 4 above.

Embodiment of the present utility model: the parameters such as the feature of the multiple beam type precast beam 4 of bearing according to precast beam place and geologic information, calculate and select each deposit parameter and the quantity of required pile tube 1 under beam fulcrum and carry out reasonable Arrangement.

According to suitable inverted T-shaped cushion cap 2 sizes of design such as pile tube 1 arrangement pitch, precast beam 4 support positions, cushion cap 2 force requests.

Precast beam 4 adopts four fulcrums to deposit, and deposits the longitudinal two-end structure of beam pedestal the same, and longitudinal pitch requires to arrange according to the beam span of depositing of precast beam 4.

According to the difference of the precast beam 4 bearing horizontal spacings of different beam types, on cushion cap 2, place respectively support plate 3 and carry out various Liang Xingxiangliang and deposit.

As shown in Fig. 5, Fig. 6, Fig. 7, be that three kinds of different beam type individual layers on the utility model of bearing horizontal spacing are deposited schematic diagram.
