Abstract
The invention discloses a large-altitude-difference variable-section concrete structure construction joint and a construction method thereof. The construction joint is used for construction of a large-altitude-difference variable-section concrete structure, and comprises an upper layer structure and a lower layer structure. The upper layer structure and the lower layer structure are respectively provided with staggered edges, and vertical inserting ribs are arranged between the staggered edges of the upper layer structure and the staggered edges of the lower layer structure. The construction method comprises the steps that concrete is poured to the lower layer structure and poured to the bottoms of the openings of the staggered edges, the vertical inserting ribs are horizontally and evenly embedded in the lower layer structure, staggered edge opening hanging formworks are arranged on the lower layer structure, concrete is poured to staggered edge openings, and construction of the large-altitude-difference variable-section concrete structure construction joint is completed. The relative sliding problem of structures at the large-altitude-difference variable-section concrete structure construction joint can be solved, the construction joint arranging method is simple, and construction operation is convenient and quick; concrete is poured twice, the upper layer structure and the lower layer structure can be constructed in a flow construction mode, and cracks due to the fact that the thickness of concrete poured one time is too large are effectively avoided.
Description
Technical field
The present invention relates to a kind of constuction joint and construction method thereof, especially a kind of large discrepancy in elevation variable cross-section concrete structure construction seam and construction method thereof.
Background technology
At present, the normal method that adopts disposable continuous construction of large discrepancy in elevation variable cross-section concrete structure construction, the i.e. reinforcing bar of first colligation levels structure, then concreting together.This kind of way has several shortcomings to be: one,, due to must the whole colligations of the reinforcing bar of levels structure are complete before concreting, affect construction speed.Two, because variable cross-section place formwork reinforcement system is made the strong point without concrete surface, formwork reinforcement difficulty, danger is larger.Three, to uprise poor place concrete thickness large for structure, the variations in temperature that cementitious material aquation causes and shrink the generation that easily causes crack.
Summary of the invention
In order to solve, disposable continuous construction speed is slow, formwork reinforcement is difficult, construction is dangerous greatly, once-cast concrete thickness great Yi produces the problem in crack, the invention provides that a kind of speed of application is fast, quality good, construction method is simple, construction safety is guaranteed, and can effectively avoid once-cast concrete thickness great Yi to produce large discrepancy in elevation variable cross-section concrete structure construction seam and the construction method thereof in crack.
Technical problem to be solved by this invention is achieved through the following technical solutions:
A kind of large discrepancy in elevation variable cross-section concrete structure construction seam, comprises superstructure and substructure, in described superstructure and substructure, is respectively equipped with horse tooth trough, between described superstructure horse tooth trough and substructure horse tooth trough, is provided with vertical joint bar.
Described superstructure horse tooth trough Cha Kou and the corresponding setting of substructure horse tooth trough raft mouth, conveniently connect raft.
It is the scope of 200-500mm that described substructure horse tooth trough raft mouth bottom exceeds distance than substructure end face.
The scope that described horse tooth trough raft open height is 300-600mm.
Described vertical joint bar is imbedded the scope that the substructure degree of depth is 500-800mm, and described vertical joint bar is inserted the scope that the superstructure degree of depth is 400-700mm.
Described vertical joint bar level is uniformly distributed between superstructure and substructure, the scope that described vertical joint bar level interval is 500-1000mm.
Described large discrepancy in elevation variable cross-section concrete structure construction seam, its construction method comprises:
1), to substructure fluid concrete, concreting is to horse tooth trough raft mouth bottom;
2) in substructure, level is evenly buried vertical joint bar underground;
3) in substructure, install horse tooth trough Cha Kou and hang mould;
4) cast horse tooth trough raft mouth concrete;
5) complete the construction of large discrepancy in elevation variable cross-section concrete structure construction seam.
The invention has the beneficial effects as follows:
This large discrepancy in elevation variable cross-section concrete structure construction seam and construction method thereof arrange vertical joint bar between levels structure horse tooth trough, can effectively solve the relative slippage problem of large discrepancy in elevation variable cross-section concrete structure construction seam place structure, guarantee the Safety and Quality of construction; This setting-up of construction joint method is simple, and constructing operation easily and fast; The concrete of large discrepancy in elevation variable section structure is built at twice, and superstructure and substructure can be carried out flowing water construction, and speed of application is accelerated, and can effectively avoid because of the excessive crack causing of one-time-concreting concrete thickness.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
In figure, 1. horse tooth trough, 2. vertical joint bar, 3. substructure, 4. superstructure.
The specific embodiment
