Abstract
The invention discloses plug construction methods inside box beam at a kind of continuous small box girder wet joint, include the following steps: S1: transporting after the completion of beam body tensioning mud jacking to beam strorage area；S2: brick is transported to scene；S3: locking plug template position is drawn in the box beam for needing plug；S4: scene has reconciled M7.5 mortar；S5: using brick in small box girder locking plug template position masonry wall locking plug template；S6: it after the completion of masonry, as box beam locking plug template, stays in inside box beam.Easy construction of the present invention, quick construction；Sealing effect is good, firm.
Description
Technical field
The invention belongs to plug construction technologies in box beam at a kind of continuous small box girder wet joint, in particular to a kind of continuous small
Plug construction method inside box beam at box beam wet joint.
Background technique
In Design for Bridge along Expressway, small box girder structure is often devised.The most of small box girder structural bridges in the north are set
It is calculated as continuous small box girder, small box girder is connected using hogging moment steel strand wires, and small box girder is hollow structure, is pouring continuous joint
Connector concrete should be poured using template.In joint, concrete blinding is designed as preformed reinforced concrete shuttering, needs to carry out
Installation is reinforced, and constructing operation is cumbersome.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of rapid construction, construction easy to use are small
The method of box beam locking plug template
The purpose of the present invention is achieved through the following technical solutions: at a kind of continuous small box girder wet joint inside box beam
Plug construction method, includes the following steps:
S1: it transports after the completion of beam body tensioning mud jacking to beam strorage area；
S2: brick is transported to scene；
S3: locking plug template position is drawn in the box beam for needing plug；
S4: scene has reconciled M7.5 mortar；
S5: using brick in small box girder locking plug template position masonry wall locking plug template；
S6: it after the completion of masonry, as box beam locking plug template, stays in inside box beam.
It is preferred that brick is using the useless brick in removal house, it is low in cost using discarded brick of removing.
The beneficial effects of the present invention are: easy construction of the present invention, quick construction；Sealing effect is good, firm.
Detailed description of the invention
Fig. 1 is plug brick template installation diagram in box beam；
In figure, 1- small box girder contour line, the brick inner template of 2-.
Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawing, but protection scope of the present invention is not limited to
It is as described below.
As shown in Figure 1, box beam inside plug construction method at a kind of continuous small box girder wet joint, includes the following steps:
S1: it transports after the completion of beam body tensioning mud jacking to beam strorage area；
S2: brick is transported to scene；
S3: locking plug template position is drawn in the box beam for needing plug；
S4: scene has reconciled M7.5 mortar；
S5: as shown in Figure 1 in small box girder contour line using brick in small box girder locking plug template position masonry wall locking plug template
Brick inner template 2 is built in 1；
S6: it after the completion of masonry, as box beam locking plug template, stays in inside box beam.
In a preferred embodiment, brick is low in cost using discarded brick of removing using the useless brick in removal house.
The present invention:
1, according to on-site actual situations, discarded brick is selected.
2, the reconciliation M7.5 mortar after the completion of tensioning mud jacking of beam field.
3, brick wall template is built inside small box girder is continuously held.
4, this plug is easy for construction, consolidates, low in cost.
The present invention reaches the construction requirement of small box girder locking plug template, firm, easy for construction, low in cost, is to have higher push away
Wide application value.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, it is noted that all
Made any modifications, equivalent replacements, and improvements etc. within the spirit and principles in the present invention should be included in guarantor of the invention
Within the scope of shield.
