Description

一种空心板桥梁 技术领域
本发明涉及一种空心板桥梁。
 背景技术
空心板多用于中小跨径桥梁，其采用预制装配方式，现有的空心板桥梁多采用多组空心板梁沿桥梁跨度依次布置，相邻空心板梁之间设置铰缝，铰缝包括铰缝框架和填充的混凝土，这种空心板桥梁在使用多年后，容易出现个别空心板梁损坏的情况，就需要更换损坏的空心桥梁。由于距离桥梁建设的时间太长，通常不会预留空心板梁，目前主要采用两种方式进行维修：1、现场浇筑板梁；2、更换预制的空心板梁。在施工现场浇筑板梁时，不仅需要布置模板和支架等，费工费时，由于混凝土用量较大，需要特别长的混凝土养护时间，施工周期特别长，对交通正常通行影响较大。向厂家定制控制板梁时，由于空心板梁是混凝土浇筑成型的，考虑到混凝土养护时间，定制耗费时间特别长，也会延长施工周期，对交通正常通行影响较大。
 技术问题
针对现有技术存在的不足，本发明的目的在于提供一种空心板桥梁，以解决现有技术中在更换个别损坏的空心板梁时需要向厂家定制空心板梁导致施工周期较长而影响交通的技术问题。
 技术解决方案
一种空心板桥梁，包括。
梁体，包括多片沿梁体左右跨度方向依次排布的空心板梁，各空心板梁均沿梁体左右宽度方向延伸，钢梁结构件，沿梁体前后宽度方向延伸，在钢梁结构件与相应旁侧的空心板梁之间灌浆以形成铰缝，将所述的相应旁侧的空心板梁定义为钢梁邻接梁，兜底连接板，与钢梁结构件通过紧固螺栓可拆固定连接，所述兜底连接板位于所述钢梁邻接梁下方并与钢梁邻接梁固定连接，以在灌浆形成铰缝时兜底封挡混凝土，钢梁现浇铺装层钢筋，与所述钢梁结构件上部连接，并与所述钢梁邻接梁上方的旁侧现浇铺装层钢筋固定连接，混凝土现浇铺装层，覆盖所述钢梁结构件和钢梁现浇铺装层钢筋，形成钢混组合结构。
 有益效果
本发明所提供的空心板桥梁中，当需要加长空心板桥梁长度时或者是当需要替换损坏的空心板梁时，可采用钢梁结构件替换空心板梁，利用兜底连接板将钢梁结构件与钢梁邻接梁连接后，在钢梁结构件和钢梁邻接梁之间灌浆以形成铰缝，从而将钢梁结构件与空心板梁固定连接在一起，并将钢梁现浇铺装层钢筋与旁侧现浇铺装层钢筋固定连接，并利用顶部灌浆形成钢混组合结构，有效提高空心板桥梁的整体强度。采用钢梁结构件替换空心板梁时，不需要向厂家定制空心板梁，省去了厂家制作空心板梁的混凝土养护时间，有效缩短了桥梁维护时间，降低了维护成本，施工较为方便，便于快速更换维护。

 本发明的最佳实施方式
实施例一，该空心板桥梁主要包括梁体，梁体包括多个沿梁体左右跨度方向依次排布的空心板梁，各空心板梁均沿梁体左右宽度方向延伸，多个空心板梁固定连接以形成支撑。
本实施例中的空心板桥梁是用钢梁结构件300作为中间钢梁结构件替换掉个别损坏的空心板梁后的空心板桥梁。
两空心板梁100沿空心板桥梁左右跨度方向间隔分布以形成安装空位，钢梁结构件300位于安装空位处，两个空心板梁均为钢梁邻接梁，钢梁邻接梁与钢梁结构件300之间形成间隔缝，在间隔缝中灌浆以形成铰缝200，实现钢梁邻接梁和中间钢梁结构件的固定连接。
钢梁结构件的结构，包括左侧腹板1、右侧腹板7、横向连接板6、横隔板4、左侧底板3和右侧底板8，横向连接板6和横隔板4作为中间下连接件位于两侧腹板之间，并与两侧腹板内侧焊接连接，左侧底板3焊接连接于左侧腹板1底部，右侧底板8焊接连接于右侧腹板7的底部，并且，两侧底板与中间的横隔板4也焊接连接，形成箱梁式的结构件。
上述左侧腹板1和右侧腹板7均为波形钢腹板，横向连接板6位于横隔板4上方，横向连接板6的左右两侧与两侧腹板的内侧面焊接连接，由于腹板为波形结构，为保证贴合，横向连接板的左右端部也设计成波形结构，与腹板结构吻合，提高结合能力。
上述的横隔板4沿前后方向依次间隔分布多个，横隔板4的上端与横向连接板6焊接连接，左右两端与两侧腹板焊接连接，下端则与两侧底板焊接连接。
上述的横向连接板6和横隔板4作为中间连接结构支撑两侧腹板，并且，横向连接板6沿前后方向延伸，并与两侧腹板形成槽型结构，以方便容纳混凝土。
为方便维护检修钢梁结构件内部，此处的左侧底板3和右侧底板8设计成分隔结构，两者之间形成维修间隔。
对于两侧底板来讲，其与相应侧腹板垂直焊接连接，此处的两侧底板均为兜底安装底板，用于固定连接相应的兜底连接板。为方便连接横隔板4和相应侧的兜底连接板，以左侧底板为例，左侧底板具有位于两侧腹板相向内侧的内侧板部31和位于两侧腹板相背外侧的外侧板部32，内侧板部31与横隔板4底部焊接连接，外侧板部32则通过螺栓连接结构与相应侧的兜底连接板固定连接，连接较为方便。
两侧兜底连接板的结构相同，在此以左侧兜底连接板2为例介绍，左侧兜底连接板2一侧通过紧固螺栓与左侧底板3固定连接，另一侧则与相应侧空心板梁100粘接固定。在将钢梁连接件下入间隔缝后，从桥梁下方将左侧兜底连接板2固定连接在左侧底板3底部，然后上提钢梁结构件300，使左侧兜底连接板2粘接固定在相应侧空心板梁100底部。
以左侧兜底连接板2为例介绍：如图5所示，左侧兜底连接板2包括错位布置的外连接部21和内连接部22，两连接部通过倾斜连接板部连接，左侧兜底连接板2中的内连接部22相对外连接部21向下错位布置，以在左侧兜底连接板上形成错位台阶602。内连接部22具体通过紧固螺栓与左侧底板3的外侧板部32固定连接，外连接部21则通过粘接的方式与相应侧的空心板梁固定连接。
而且，各空心板梁100的下侧面分别具有朝向钢梁结构件300突出布置的内端101，外连接部位于相应侧内端101的外侧，进而与兜底连接板上的错位台阶602配合，使得形成于钢梁结构件与相应旁侧的钢梁邻接梁之间的铰缝底部为钩形结构603，该钩形结构603可有效提高钢梁结构件与空心板梁100的连接强度。
本实施例中，在两侧腹板的上部分别设有穿孔401，两排穿孔在左右方向上一一对应以形成穿孔对，在各穿孔对中分别对应穿装一根穿孔钢筋400，使得穿孔钢筋400沿左右方向延伸并沿前后方向依次间隔分布多个，穿孔钢筋左右两端与相应侧空心板梁上方的旁侧现浇浇铺装层钢筋绑扎或焊接连接。
然后向钢梁结构件300上方灌浆，以形成混凝土现浇铺装层，混凝土现浇铺装层覆盖钢梁结构件、钢梁现浇铺装层钢筋和旁侧现浇铺装层钢筋，以形成钢混组合结构。
为提高钢梁结构件与混凝土的结合力，在两侧腹板的相背外侧以及横向连接板的上侧分别突出布置有栓钉，栓钉采用焊接连接的方式固定于相应板的侧面上，混凝土灌浆凝固后，栓钉会进入混凝土中，提高结合性能。
 本发明的实施方式
实施例二，在对端部空心板梁进行更换时，空心桥梁中。
钢梁结构件300为布置于所述梁体端部的端部钢梁结构件10，端部钢梁结构件10的旁侧布置有所述的钢梁邻接梁，端部钢梁结构件10的朝向所述钢梁邻接梁的一侧腹板为所述的铰缝15腹板。
因此我们只需要在端部钢梁结构件仅在右侧底板11底部通过紧固螺栓可拆连接有兜底连接板12，其他的连接方式还是和实施例1一样，然后向端部钢梁结构件顶部灌浆，形成混凝土现浇铺装层，包括现浇层16，覆盖顶部钢梁结构件、钢梁现浇铺装层钢筋和旁侧现浇铺装层钢筋，形成钢混组合结构。
实施例三，主要是针对中间空心板梁两侧均需要设置钢梁结构件300时。
此处的左侧钢梁结构件90和右侧钢梁结构件95与上述实施例1中的中间钢梁结构件的结构相同，只是在左侧钢梁结构件90还是右侧钢梁结构件95之间固定连接有横向加强连接件93，横向加强连接件93具体为槽钢，槽钢沿相应钢梁结构件的前后长度方向依次间隔布置有多个，各横向加强连接件93的左端与左侧钢梁结构件90的右侧底板92的上侧面焊接连接，各横向加强连接件93的右端与右侧钢梁结构件95的左侧底板94的上侧面焊接连接，以将相近的两个钢梁结构件固定连接在一起，提高桥梁整体性及结构稳定性。
在本实施例中，横向加强连接件具体为槽钢，在其他实施例中，横向加强连接件也可以矩形管或圆管或者是加强板等结构。当然，横向加强连接件也可以为沿前后方向延伸的连接板，连接板可通过紧固螺栓与两侧底板固定连接在一起，即连接板可与相应侧兜底连接板压装在一起，通过相同的紧固螺栓实现相应侧底板、连接板及相应侧兜底连接板的固定连接。
在两侧钢梁结构件上部穿装穿孔钢筋96，以形成钢筋现浇铺装层钢筋，用于与旁侧空心板梁上方的旁侧现浇铺装层钢筋固定连接。
为提高结构强度，穿孔钢筋96可覆盖左侧钢梁结构件、中间空心板梁和右侧钢梁结构件。最后在钢梁结构件上方灌浆，再设置现浇层和铺装层即可。
另外，需要说明的是，可以认为利用横向加强连接件连接的两钢梁结构件形成一个钢梁结构件组，在其他实施例中，在空心板桥梁上如果在较近的距离内布置三个或四个以上的钢梁结构件时，间隔相邻的两两钢梁结构件形成一个钢梁结构件组，并利用横向加强连接件将相邻两钢梁结构件固定连接在一起，以提高整个桥梁稳定性。而且，钢梁结构件可以为中间钢梁结构件，也可以为端部钢梁结构件，一般来讲，同一钢梁结构件组中任意相邻的两钢梁结构件中间会设置一个或两个空心板梁，距离不适宜太远。
 工业实用性
本发明所提供的空心板桥梁是将个别损坏的空心板梁替换后的结构，其相较于传统的采用空心板梁更换的方案，采用钢梁结构件可在工厂焊接加工成型，加工安装较为方便，避免了工厂预制空心板梁中的混凝土养护时间，便于快速更换损坏的空心板梁，以快速修复加固桥梁，有效缩短了维修周期，减少了交通的影响，具有较大的推广价值。
