背景技术 Background technique
随着现代建筑工业化程度的提高，带纵向肋的预应力钢筋混凝土叠合板得到了越来越广泛的应用，其抗裂性能好，减少了模板支护，施工周期短，并且由于纵向肋两侧开有各种形状的孔洞，能有效减小板的反拱值，使板底平整，其后浇混凝土叠合层后又具有混凝土现浇结构整体性好的优点。但由于纵向肋两侧开口较小，在施工过程中水电等管线穿过孔洞比较困难，需要进行现场扩孔，此时有将纵向肋或底板内的钢筋切断的危险，同时也增加了施工的难度，延长工期，并且有使预制板承载力下降的可能。 With the improvement of the industrialization of modern buildings, prestressed reinforced concrete composite slabs with longitudinal ribs have been more and more widely used. It has good crack resistance, reduces formwork support, and has a short construction period. There are holes of various shapes, which can effectively reduce the anti-arch value of the slab and make the bottom of the slab flat. After pouring the concrete laminated layer, it has the advantage of good integrity of the concrete cast-in-place structure. However, due to the small openings on both sides of the longitudinal rib, it is difficult for pipelines such as water and electricity to pass through the hole during construction, and on-site reaming is required. At this time, there is a danger of cutting the longitudinal rib or the steel bars in the bottom plate, and it also increases the construction work. Difficulty, prolonging the construction period, and the possibility of reducing the bearing capacity of the prefabricated slab.

具体实施方式 detailed description
下面结合附图及实施例对本发明进行详细说明，但实施例对本发明不做任何形式的限定。 The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the embodiments do not limit the present invention in any form.
参见图1、图2、图3、图4、图5，一种带断肋预应力钢筋混凝土叠合板，由预应力钢筋混凝土底板1、混凝土纵向肋2构成，混凝土纵向肋2可以是单肋，也可以是双肋，混凝土纵向肋2上开设有断肋口5，混凝土纵向肋2的底部开有间隔排列的横向贯通孔3，底板、纵向肋分别埋设预应力钢筋4和纵向肋内部纵筋6，纵向肋内部纵筋6穿过断肋口5形成非间断式钢筋。 Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a prestressed reinforced concrete composite slab with broken ribs is composed of a prestressed reinforced concrete bottom plate 1 and a concrete longitudinal rib 2, and the concrete longitudinal rib 2 can be a single rib , can also be double ribs, the concrete longitudinal rib 2 is provided with broken rib openings 5, the bottom of the concrete longitudinal rib 2 is provided with transverse through-holes 3 arranged at intervals, the bottom plate and the longitudinal rib are respectively embedded with prestressed steel bars 4 and longitudinal ribs inside the longitudinal ribs. Rib 6, the inner longitudinal rib 6 of the longitudinal rib passes through the broken rib opening 5 to form an uninterrupted reinforcing bar.
断肋口5可位于混凝土纵向肋2的中间位置，成为等长度两段式断肋；断肋口5也可偏离中间位置，成为不等长度两段式断肋；双肋时，两条混凝土纵向肋2的断肋口5，可以均在中间位置，也可以同向偏离中间位置，这两种情况可称为平行式断肋，或者向相反方向偏离中间位置，这种情况可称为交错式断肋。这样既能够在断肋口5处有足够的空间穿各种管线，又能够在后续的现浇混凝土叠合层时提高整体性，减小底板的反拱值。由于整块楼板穿管线需要在混凝土纵向肋2上设置不同位置的断肋口5，所以应将等间距断肋及不等间距断肋协同考虑，按着一定的顺序排列成整块楼板，以达到最佳的管线敷设效果，降低施工难度，缩短工期。 The broken rib opening 5 can be located in the middle of the concrete longitudinal rib 2 to become a two-stage broken rib of equal length; the broken rib opening 5 can also deviate from the middle position to become a two-stage broken rib of unequal length; The broken rib openings 5 of the longitudinal ribs 2 can all be in the middle position, or they can deviate from the middle position in the same direction. These two cases can be called parallel broken ribs, or they can deviate from the middle position in the opposite direction. This kind of situation can be called staggered Broken ribs. In this way, not only can there be enough space to pass various pipelines at the broken rib opening 5, but also the integrity can be improved in the subsequent cast-in-place concrete lamination layer, and the anti-arch value of the bottom plate can be reduced. Since the whole floor slab needs to set broken rib openings 5 at different positions on the concrete longitudinal rib 2, the equal-spaced broken ribs and unequal-spaced broken ribs should be considered together and arranged in a certain order to form the whole floor. Achieve the best pipeline laying effect, reduce construction difficulty and shorten construction period.
本实施例所述的带断肋预应力钢筋混凝土叠合板，其制作方法如下： The band broken rib prestressed reinforced concrete laminated plate described in the present embodiment, its manufacture method is as follows:
（1）将预应力钢筋混凝土底板1的模板、混凝土纵向肋2的模板支好，绑扎钢筋，纵向肋内部纵筋6在断肋口5位置不间断，是连续的； (1) Support the formwork of the prestressed reinforced concrete bottom slab 1 and the formwork of the concrete longitudinal rib 2, and bind the steel bars. The inner longitudinal reinforcement 6 of the longitudinal rib is uninterrupted and continuous at the position of the broken rib opening 5;
（2）张拉预应力钢筋4； (2) Tensile prestressed steel bar 4;
（3）浇筑混凝土，将底板及纵向肋一体浇筑成型并养护； (3) Pouring concrete, integrally pouring and curing the bottom plate and longitudinal ribs;
（4）放松预应力钢筋4，即形成带断肋预应力钢筋混凝土叠合板。 (4) Loosen the prestressed reinforcement 4 to form a prestressed reinforced concrete composite slab with broken ribs.
以上所述，仅是本发明较佳的实施例而已，并非对发明作任何形式上的限制。凡是依据本发明的纵向肋间断技术对以上实施例所作的任何简单修改、等同变化与修饰，均属于本发明的保护范围。 The above descriptions are only preferred embodiments of the present invention, and do not limit the invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments according to the longitudinal rib interruption technology of the present invention belong to the protection scope of the present invention.
