Description
技术领域technical field
本发明涉及建筑工业化领域，具体涉及一种新型预制装配式混凝土多孔楼板及其制作方法。The invention relates to the field of building industrialization, in particular to a novel prefabricated concrete porous floor slab and a manufacturing method thereof.
背景技术Background technique
近年来在国家大力提倡现代建筑产业化的背景下，我国装配式建筑开始大面积出现，建筑设计标准化，建筑部品系列化，构件生产工厂化得到飞速发展。In recent years, under the background that the country has vigorously advocated the industrialization of modern buildings, my country's prefabricated buildings have begun to appear on a large scale, with standardized architectural design, serialization of building parts, and factory production of components have developed rapidly.
原预制混凝土多孔楼板多为整体式、且剖面形式为梯形，在两块多孔楼板之间间隙和面层采用素混凝土整浇，以增强楼板整体性，但由于预制板构造和施工的原因，会出现以下的技术问题和缺陷：Most of the original prefabricated concrete porous floors are monolithic, and the cross-section is trapezoidal. The gap between the two porous floors and the surface layer are poured with plain concrete to enhance the integrity of the floor. However, due to the structure and construction of the prefabricated slab, it will The following technical problems and defects arise:
1.素混凝土与预制板间粘结性不好，面层经常会脱开；1. The bonding between plain concrete and prefabricated panels is not good, and the surface layer often falls off;
2.素混凝土流动性较差，板缝间饱满度不足，建筑不均匀沉降或变形时容易造成楼板开裂，漏水；2. The fluidity of plain concrete is poor, and the fullness between the slab joints is insufficient. When the building is unevenly settled or deformed, it is easy to cause floor cracking and water leakage;
3.素混凝土易起鼓、脱落，装修阶段经常会被破坏，失去了原设计作用，造成楼板整体抗震性能差，地震时易脱落。3. Plain concrete is easy to bulge and fall off. It is often damaged during the decoration stage, losing its original design function, resulting in poor overall seismic performance of the floor slab and easy to fall off during an earthquake.
上世纪末我国掀起了住宅产业化建设新浪潮，据不完全统计，我国每年的住宅建设量约为15亿立方米，其中城镇住宅建设量约占1/3，可见住宅产业是我国国民经济的重要组成部分。然而预制混凝土也存在以下几个方面的缺点：At the end of the last century, my country set off a new wave of housing industrialization construction. According to incomplete statistics, the annual housing construction volume in my country is about 1.5 billion cubic meters, of which urban housing construction accounts for about 1/3. It can be seen that the housing industry is an important part of my country's national economy. component. However, precast concrete also has the following disadvantages:
(1)整体性较差(1) Integrity is poor
预制混凝土结构是预制构件在施工现场进行拼装完成的，在没有精心设计拼装节点且施工质量不能保证的情况下，就很容易出现结构的整体性差的情况，在过去的一些地震中发现部分预制混凝土结构破坏比较严重，造成严重的人员伤亡及财产损失。The precast concrete structure is assembled by prefabricated components at the construction site. Without careful design of the assembled joints and the construction quality cannot be guaranteed, it is easy to have poor structural integrity. Some precast concrete structures were found in some earthquakes in the past Structural damage is relatively serious, resulting in serious casualties and property losses.
(2)设计难度比较大(2) The design is more difficult
由于预制混凝土技术还不够成熟，预制混凝土节点构造比较复杂，设计难度比较大，结构设计人员仅熟悉现浇混凝土结构的设计方法，对预制混凝土结构的设计方法和特点比较陌生，且行业内与预制混凝土结构相关设计规范及标准比较稀少。Because precast concrete technology is not mature enough, the structure of precast concrete joints is relatively complex, and the design is relatively difficult. Structural designers are only familiar with the design methods of cast-in-place concrete structures, and are relatively unfamiliar with the design methods and characteristics of precast concrete structures. Relevant design codes and standards for concrete structures are relatively rare.

实施例二Embodiment two
如图6所示，提供一种新型预制装配式混凝土多孔楼板，包括左边板1，中间板2，右边板3，在左边板1、中间板2和右边板3上都开有圆孔4和埋有预应力钢筋5，左边板1、中间板2和右边板3厚度相同为120mm，单个板宽度为500mm；其与实施例一最大的区别在于单个板宽度较宽，适用于建筑空间具有较大跨度需求的情况。As shown in Figure 6, a novel prefabricated concrete perforated floor slab is provided, comprising a left panel 1, a middle panel 2, and a right panel 3, and circular holes 4 and 4 are provided on the left panel 1, the middle panel 2 and the right panel 3. Embedded with prestressed steel bars 5, the thickness of the left panel 1, middle panel 2 and right panel 3 is the same as 120mm, and the width of a single panel is 500mm; the biggest difference between it and Embodiment 1 is that the width of a single panel is wider, which is suitable for building spaces with relatively large The case of long-span demand.
当然根据需求，左边板1、中间板2、右边板3可以是400mm、500mm、600mm系列中任意一组数值的组合应用。Of course, according to the requirements, the left panel 1, the middle panel 2, and the right panel 3 can be combined applications of any set of values in the 400mm, 500mm, and 600mm series.
进一步，本发明提供一种新型预制装配式混凝土多孔楼板的制作方法，包括以下步骤：Further, the present invention provides a method for making a novel prefabricated concrete porous floor, comprising the following steps:
S01：根据左边板、中间板和右边板多孔楼板的宽度及截面形状进行模板设计和制作，生成具有灌浆孔的多孔楼板；S01: Design and manufacture formwork according to the width and cross-sectional shape of the perforated slabs on the left, middle and right slabs to generate perforated floors with grouting holes;
S02：绑扎多孔楼板钢筋网架，在多孔楼板钢筋网架内设置波纹管；S02: Bind the porous floor steel grid frame, and set bellows in the porous floor steel grid frame;
S03：向多孔楼板钢筋网架内浇筑已配置好的混凝土，并清理波纹管孔道；S03: Pour the configured concrete into the porous floor steel grid, and clean the bellows channel;
S04：拆除模板，向左边板、中间板和右边板内穿放预应力钢筋束；S04: Remove the formwork, and put prestressed tendons into the left panel, middle panel and right panel;
S05：预应力钢筋束张拉，向左边板、中间板和右边板的预应力钢筋束孔道压浆，预应力钢筋束端通过压入的浆体进行端口密封；S05: Tensioning of the prestressed tendon, grouting to the prestressed tendon channels of the left plate, middle plate and right plate, and the end of the prestressed tendon is sealed by the pressed grout;
S06：采用外部起重机对左边板、中间板和右边板起吊、存放；S06: Use an external crane to lift and store the left panel, middle panel and right panel;
S07：将多块左边板、中间板和右边板依次相连组合，并从灌浆孔进行灌浆密封。S07: Connect multiple left panels, middle panels and right panels in sequence, and perform grouting and sealing from the grouting holes.
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明，对于本发明所属技术领域的技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those skilled in the art of the present invention, without departing from the premise of the present invention Under the circumstances, some simple deduction or replacement can also be made, which should be considered as belonging to the protection scope of the present invention.
