Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Referring to figs. 1 to Fig. 2, a kind of bridge pier bind support cover board, the present embodiment by hollow pier bind support cover board exemplified by into
Row explanation.As shown in the figure, the hollow pier binds, support cover board includes the second locking nub 2 and two the first locking nubs 1, wherein the second locking nub
2 is square, and the length of side is more than the outside diameter of hollow position at the top of hollow pier.The shape of first locking nub 1 is by three adjacent right-angle sides
Formed with arc-shaped side, two the first locking nubs 1 are symmetricly set on the opposite both sides of the second locking nub 2, each first locking nub 1 with
The opposite side of arc-shaped side is connected with the second locking nub 2 respectively and size is equal with the length of side of the second locking nub 2.First locking nub 1 and
Two locking nubs 2 are formed by the concreting higher than hollow pier pier shaft concrete strength, and particularly, each locking nub can be poured to 10cm
Thickness, support is provided for the concrete that binds, and offsets the weight for the concrete that binds and its load of generation.As shown in the figure, in first segment
The inside of 1 and second locking nub 2 of block is all equipped with the first bar-mat reinforcement 3 and the second bar-mat reinforcement 4 to match with each locking nub shape, its
In, every piece of bar-mat reinforcement is all made of screw-thread steel longitude and latitude, and the spacing of steel bar arrangement is 10cm × 10cm, and particularly, screw-thread steel is optional
With a diameter of 12 millimeters12 reinforcing bars, the skeleton using the built-in bar-mat reinforcement of each locking nub as the first locking nub 1 and the second locking nub 2,
Increase each locking nub support strength, improve 7 overall support quality of support cover board.As shown in the figure, it is both provided with above each locking nub
Two hanging rings arranged in parallel.Wherein, at the central axes of the first locking nub 1 both ends of two parallel inbuilt first hanging rings 5 with
First bar-mat reinforcement 3 of 1 laid inside of the first locking nub welds, and two parallel inbuilt second are hung at the central axes of the second locking nub 2
The both ends of ring 6 and the second bar-mat reinforcement 4 of 2 laid inside of the second locking nub weld.Particularly, hanging ring can be selected a diameter of 25 millimeters25 round steel, which are bent, to be formed, to ensure the bearing of hanging ring.Thus, each locking nub can buried preferably at the central axes of stress
There are two hanging rings, enhance the stability of each cover board locking nub of lifting so that the assembly of cover board locking nub becomes convenient, fast, can
The effectively assembled quality and progress of control support cover board 7.
With reference to Fig. 3, the assembled design sketch of the support cover board 7 of the present embodiment, since the size of each locking nub is both greater than hollow pier
The outside diameter of head space, so when carrying out capping operation, can independently lifting is positioned at the top of hollow pier in order, and and hollow pier
Chamfering 8 at come into full contact with, it is ensured that each locking nub for the cover board 7 that binds and 8 stress equalization of chamfering of hollow pier, improve the stabilization to bind
Property.So far, completion hollow pier, which binds, supports the prefabricated of cover board and sets up, and the prefabricated cover board of the present embodiment is without waiting for pier construction
Completion makes again, synchronous with bridge pier pier construction can carry out, greatly shortens the duration, and since inbuilt hanging ring provides
Can lifting operation so that operation of binding is convenient, simple and direct.The cover board that binds is not required to remove, and more conventional inner support removes operation
The danger of worker's working at height is reduced, there is very positive meaning.
It should be understood that the particular order or level of the step of during disclosed are the examples of illustrative methods.Based on setting
Count preference, it should be appreciated that during the step of particular order or level can be in the feelings for the protection domain for not departing from the disclosure
Rearranged under condition.Appended claim to a method gives the key element of various steps with exemplary order, and not
It is to be limited to the particular order or level.
