Abstract
The invention provides a construction method for an inverted conical shell structure. A horizontal structure and a vertical structure on the lower part thereof are separately constructed, wherein the vertical structure which is well constructed beforehand is used as a supporting base for a templet bent frame on the bottom of the horizontal structure; after concrete is cast on the horizontal structure and is pressed and impacted, the ringent part of the surface of the horizontal structure is sealed to prevent concrete from overflowing from the ringent part of the surface of the horizontal structure when the upper vertical structure is cast by the concrete; and finally the upper vertical structure is cast, therefore, the problem that the geometric dimension of the horizontal structure and the compactibility of the concrete can not be guaranteed is solved, the construction joints are reduced, and the construction period is shortened.
Description
Technical field
The present invention relates to a kind of construction techniques, particularly relate to a kind of job practices that is used for inverted conical shell structure.
Background technology
In the building structure construction process, routine takes to construct synchronously with its underpart vertical structure, constuction joint is stayed the job practices that is located at the horizontal structure face during construction level structure, perhaps take the horizontal structure job practices of construction separately, these traditional job practicess help guaranteeing the physical dimension and the concrete density of horizontal structure.Yet under special construction, special operation condition and construction speed requirement situation, particularly in inverted conical shell structure, since the vertical structure in this structure be outward-dipping structure (with horizontal plane angle be 120 °～135 °), according to above-mentioned first kind of conventional construction method, because the template framed bent of horizontal structure bottom is supported on the vertical structure that does not equally also have construction, the template framed bent can not get solid strong support degree, makes the physical dimension of horizontal structure and concrete density be difficult to reach requirement; According to above-mentioned second kind of conventional job practices, up and down each is produced one constuction joint at horizontal structure, stay and establish too much constuction joint, the intractability to the constuction joint seam increases on the one hand, has delayed construction speed on the other hand.For this reason, for inverted conical shell structure, traditional job practices just is difficult to be suitable for.
Summary of the invention
A kind of job practices that is used for inverted conical shell structure provided by the invention, by horizontal structure and its underpart vertical structure are separated construction, utilize the supporting base of the good vertical structure of construction in advance as horizontal structure bottom template framed bent, again horizontal structure surface opening position is sealed after then building horizontal structure concrete and vibration compacting, concrete overflows from horizontal structure surface opening position when avoiding building top vertical structure concrete, and then build the top vertical structure, thereby overcome the problem that horizontal structure physical dimension and concrete density are difficult to guarantee, reduce constuction joint again and stay and establish, shorten the construction period.
In order to achieve the above object, the invention provides a kind of job practices that is used for inverted conical shell structure, comprise following steps:
First horizontal structure of step 1, construction foot and first vertical structure on top thereof, and carry out concrete curing;
The template framed bent of step 2, construction second horizontal structure and top second vertical structure thereof;
The template system at step 4, the construction second horizontal structure surface opening position seals the second horizontal structure surface opening position;
If will continue more multilevel structure of construction casting and vertical structure, repeat above-mentioned steps 1～5 circulation construction, finish until the overall structure construction.
The job practices that is used for inverted conical shell structure provided by the invention is compared with conventional construction technology has following advantage:
1, horizontal structure and its underpart structure are separated construction, can make the solid base that is supported with of horizontal structure bottom template framed bent, can guarantee that the template framed bent in position, concreting process axis and physical dimension deviation and distortion does not take place, thereby guarantee the physical dimension and the concrete pouring quality of horizontal structure.
2, horizontal structure and its superstructure are constructed synchronously, can reduce constuction joint and stay and establish, so promptly guarantee the globality of concrete structure, shorten the construction period again.
The present invention be specially adapted to vertical structure in the inverted conical shell structure be outward-dipping structure (with horizontal plane angle be 120 °～135 °), concrete structure quality and construction period are had higher requirements, need horizontal structure and its top vertical structure situation of construction synchronously, like this, horizontal structure physical dimension and concrete density problem can well be solved on the one hand, quality and construction period can be satisfied on the other hand.

The specific embodiment
Followingly specify better embodiment of the present invention according to Fig. 1～Fig. 4:
The invention provides a kind of job practices that is used for inverted conical shell structure, comprise the steps:
Step 1, as shown in Figure 1, first horizontal structure 1 of this construction section below of constructing and first vertical structure 2 on its top, and concrete carried out maintenance;
Step 4, as shown in Figure 4, confirm that second horizontal structure, 4 concrete vibratings that this construction section need construct are closely knit after, the template system 5 at second horizontal structure, the 4 surface opening positions of constructing immediately, and with 3 fixations of template framed bent support system;
By above step 1～5 circulation constructions, pour into a mould the 3rd horizontal structure, the 3rd vertical structure, and more, finish until the overall structure construction.
A kind of job practices that is used for inverted conical shell structure provided by the invention, by horizontal structure and its underpart vertical structure are separated construction, utilize the supporting base of the good vertical structure of construction in advance as horizontal structure bottom template framed bent, again horizontal structure surface opening position is sealed after then building horizontal structure concrete and vibration compacting, concrete overflows from horizontal structure surface opening position when avoiding building top vertical structure concrete, and then build the top vertical structure, thereby overcome the problem that horizontal structure physical dimension and concrete density are difficult to guarantee, reduce constuction joint again and stay and establish, shorten the construction period.
