Problems solved by technology

[0004] Generally, different types of segmental beam formworks are used in the production of segmental beams. Since the segmental beam formworks in the prior art are produced through the cooperation of fixed formwork bodies and fixed shear keys, it can be produced The type of segmental beam is relatively simple; when it is necessary to produce a variety of segmental beams, different types of segmental beam formwork are required; in addition, the existing segmental beam formwork is in the process of producing segmental beams between the formwork body and the shear key. It is also prone to loosening, which will lead to unqualified segmental beam products

Embodiment 1

[0028] See figure 1 , In Embodiment 1 of the present invention, a segment beam end template includes: a segment beam end template body 1 for constructing a foundation of different segment beam end templates and a segment beam end template body 1 used to form Shear keys of different section beam end templates; the middle inside of the section beam end template body 1 is a template end 4, which is used to form a segment beam end; the shear keys are divided into two types, They are the first shear key 2 and the second shear key 5; the first shear key 2 and the segment beam end template body 1 are easily disassembled and assembled, and the second shear key 5 and the segment beam end template Easy to disassemble and assemble between the main body 1;

[0029] Through different types of shear keys, such as the first shear key 2, such as the second shear key 5, cooperate with the segment beam end template body 1 to form different types of segment beam end templates, and then manufacture ...

Embodiment 2

[0033] See Figure 4 with Figure 5 Further, the section beam end template body 1 and the second shear key 5 are connected and fixed by a second fixing buckle 7.

[0034] Specifically, the section beam end template body 1 is provided with a through hole on the right side, the second shear key 5 is provided with a screw 8 on the left side, and the second fixing buckle 7 is provided with internal threads;

[0035] When the segment beam end template body 1 and the second shear key 5 are assembled, the screw 8 on the side of the second shear key 5 penetrates the through hole of the segment beam end template body 1 and extends into the segment beam end template body 1 inside, then the internal thread of the second fixing buckle 7 is connected with the surface of the screw 8 by interference fit, so that the section beam end template body 1 and the second shear key 5 are assembled.

[0036] Furthermore, in order to prevent loosening between the second fixing buckle 7 and the screw 8 of the...

Abstract

The invention relates to the technical field of segmental beam manufacturing, and particularly discloses a segmental beam end formwork which comprises a segmental beam end formwork body used for constructing different segmental beam end formwork foundations and shear keys used for being matched with the segmental beam end formwork body to form different segmental beam end formworks; a formwork endis arranged in the middle of the segmental beam end formwork body, and the formwork end is used for forming a segmental beam end; and the shear keys are divided into two types, namely a first shear key and a second shear key. The segmental beam end formwork has the advantages that different types of shear keys can be matched with the segmental beam end formwork body to form different types of segmental beam end formworks, then different types of segmental beams meeting building construction requirements are manufactured; and the first shear key and the segmental beam end formwork body are convenient to mount and dismount, the second shear key and the segmental beam end formwork body are convenient to mount and dismount, and the mounting firmness is reliable.

Description

Technical field [0001] The invention relates to the technical field of segment beam manufacturing, in particular to a segment beam end template. Background technique [0002] With the rapid development of urban construction, traffic problems have become increasingly prominent. In order to alleviate this contradiction, the development of urban elevated roads and urban rail transit is an important measure. The construction of urban elevated roads and urban rail transit in urban centers and planned development areas not only requires a beautiful shape and high appearance quality, but also has a small impact on the surrounding environment and ground transportation. [0003] In order to reduce the impact of bridge construction on urban traffic, shorten the construction period of the bridge, and strengthen environmental protection, the segmental prefabricated cantilever assembly construction method is adopted, that is, the whole collapsed beam is divided into different segments. The shor...
