Problems solved by technology

With the airbag, it is necessary to customize the rubber airbag with the manufacturer in advance. During the construction, the rubber airbag is dragged into the steel cage. The disadvantage is that the airbag is easy to be punctured during the construction process. If the airbag is punctured, the entire T-shaped pile will be scrapped, and the versatility of the airbag Poor, all models need to be customized
Wooden molds are used to make wooden molds on site according to the size of the inner mold of the T-shaped pile. After being put into the steel cage, the surface is glued with adhesive tape. The disadvantages are that the wooden mold takes a long time to make and the cost is high. After the T-shaped pile is completed, the wooden formwork is not easy to remove

Abstract

The invention discloses a telescopic inner die. The telescopic inner die comprises a frame body sequentially encircled by a plurality of die plates, wherein the die plates are the same in length, a rotatable transmission rod is arranged in the frame body in a length direction, and the transmission rod is provided with a plurality of middle die assemblies at intervals in the axial direction; each middle die assembly comprises a middle moving block, a guide rod stretching out towards the corresponding die plate from the middle moving block, and a slide block fixed to one end of the guide rod andaway from the middle moving block; each die plate is provided with a slide way allowing the corresponding slide block to carry out reciprocating slide and inclined relative to the central axis of thetransmission rod; and the transmission rod is capable of driving the die plates to stretch towards a direction away from the transmission rod simultaneously or retreat towards the direction of the transmission rod simultaneously while driving the middle die assemblies to carry out reciprocating movement in the axial direction. The telescopic inner die has the advantages of being reasonable in structure, variable in size, and convenient to draw out.

Description

technical field [0001] The invention relates to a scalable inner mold and a T-shaped pile mold provided with a scalable inner mold, which belongs to the technical field of construction. Background technique [0002] A T-pile is a prefabricated concrete pile with a T-shaped cross-section that is often used for maintenance work. Compared with solid T-shaped piles of the same thickness, hollow T-shaped piles can ensure the bearing capacity requirements on the one hand, and save a lot of concrete on the other hand, and have been widely used in engineering practice. At present, the inner mold of the hollow T-shaped pile is mostly made of an air bag or a wooden mold. With the airbag, it is necessary to customize the rubber airbag with the manufacturer in advance. During the construction, the rubber airbag is dragged into the steel cage. The disadvantage is that the airbag is easy to be punctured during the construction process. If the airbag is punctured, the entire T-shaped pile...
