Description
Technical Field
The invention belongs to the technical field of bridge construction, and particularly relates to an integrated pouring template for a sound barrier foundation and a box girder.
Background
The sound barrier is widely used in municipal traffic facilities such as urban rail transit, highway and the like, can absorb sound and reduce noise, and reduces the influence of traffic noise on urban areas.
Taking a bridge as an example, the technology widely adopted at present is to bond reinforcing steel bars on the flange of a box girder after the box girder is poured and is condensed and hardened to reach a certain strength, install a sound barrier foundation template and pour a sound barrier foundation. The method has two main defects, namely, cement paste blocks are easily formed on the outer vertical face at the joint of the sound barrier foundation and the box girder due to template slurry leakage, and the safety risk of high-altitude edge-facing operation exists when the cement paste blocks on the outer vertical face are polished at the later stage; and secondly, the construction of the sound barrier foundation needs to be carried out after the construction of the box girder is finished, so that the construction procedures and the construction period are increased, the investment of time and labor is increased, and the engineering cost is increased.
Disclosure of Invention
The invention aims to save the outer side polishing process of the sound barrier foundation, reduce overhead edge-facing operation and reduce safety risks, and can reduce the times of template installation and concrete pouring, save construction time, reduce labor input and improve the operation efficiency and engineering benefits.
according to the technical scheme, the sound barrier foundation and box girder integrated pouring template comprises a sound barrier foundation outer side template and a sound barrier foundation inner side template, wherein the sound barrier foundation outer side template is formed by integrally extending and heightening the box girder outer side template upwards, the sound barrier foundation inner side template is made of rectangular steel plates with the same length as the sound barrier foundation outer side template, the sound barrier foundation inner side template and the sound barrier foundation outer side template are arranged in parallel, the sound barrier foundation outer side template and the sound barrier foundation inner side template are connected through a plurality of П -shaped connecting members arranged at equal intervals in the length direction, the П -shaped connecting members are formed by splicing two oppositely arranged strip-shaped angle steels after being overlapped through top surfaces and then combining bolts, the strip-shaped vertical surface of one strip-shaped angle steel is welded with the outer vertical surface of the sound barrier foundation outer side template, and the strip-shaped angle steel vertical surface of the other strip-shaped angle steel is welded with the outer vertical surface of the.
Preferably, the stiffening member is welded on the inner side formwork of the sound barrier foundation, the stiffening member is an angle steel plate which is equal to the inner side formwork of the sound barrier foundation, the vertical surface of the angle steel plate is welded with the outer vertical surface of the inner side formwork of the sound barrier foundation, and the top of the angle steel plate is welded with the bottom surface of the strip-shaped angle steel on the corresponding side. The stiffening member plays the effect of reinforcing sound barrier foundation inboard template rigidity, welds with the inboard template of sound barrier foundation, the bar angle steel of corresponding side simultaneously, and the installation is firm reliable.
further preferably, the top surface of bar angle steel is provided with at least three bolt via holes that set up along inside and outside direction equidistance interval, and every П type connecting elements is formed by at least two bolt concatenations to realize the adjustable installation of sound barrier basis outside template and sound barrier basis inboard template interval.
The invention has the beneficial effects that:
(1) The method has the advantages that the sound barrier foundation and the box girder can be integrally poured, and the steel bars are bound to install the sound barrier foundation template after the pouring of the box girder reaches a certain strength, so that the construction operation steps are simplified, the operation efficiency is improved, the construction operation period is shortened, and the economic benefit of the engineering is improved;
(2) The outer side template of the sound barrier foundation is formed by integrally extending and heightening the outer side template of the box girder upwards, so that the quality defect of the joint between the sound barrier foundation template and the box girder caused by slurry leakage of the template can be reduced and even avoided, and the attractiveness of the outer vertical surface of the bridge and the durability of the structure are improved;
(3) The traditional process for installing the sound barrier foundation formwork, particularly installing the outer side formwork of the sound barrier foundation and polishing the cement paste block of the outer vertical surface has the safety risk of high-altitude edge-facing operation, and the operation safety is high.
(4) the pouring height of the sound barrier foundation is usually about 30cm, the weight of the corresponding inner side template is small, the stress of П -shaped connecting members is not large, П -shaped connecting members are formed by overlapping two oppositely-arranged strip-shaped angle steels through top surfaces and then splicing the two strip-shaped angle steels through bolts, the sound barrier foundation is poured between the adjacent II-shaped connecting members, П -shaped connecting members are used for connecting the inner side template and the outer side template of the sound barrier foundation, the inner side template of the sound barrier foundation can be quickly installed and detached, the quick formwork erection and demolding can be further realized, meanwhile, the self weight of the inner side template and the lateral extrusion force of concrete on the inner side template of the sound barrier foundation can be transmitted to the outer side template of the sound barrier foundation, and the.
