Description
技术领域technical field
本发明涉及一种风力发电塔基础结构领域，尤其涉及一种钢桁架结构的风机基础。The invention relates to the field of a wind power generation tower foundation structure, in particular to a wind turbine foundation with a steel truss structure.
背景技术Background technique
风力发电塔在中硬地基土上的基础目前多采用独立扩展基础，这种独立扩展基础由由基础悬挑底板、承台和基础环组成的承压梁板式基础。这种独立扩展基础与适当的地基条件相配合可达到较好的抗压承载力，所以在房屋建筑类柱基中多有采用。但对于风力发电塔来说，上部结构对基础的作用力主要不是压力而是弯矩，所以传统独立扩展基础存在抗压能力有余，抗弯能力不足，造成了基础设计的较大浪费。At present, the foundation of wind power towers on medium-hard foundation soil mostly adopts independent expansion foundation. This independent expansion foundation consists of a pressure-bearing beam-slab foundation composed of foundation cantilevered bottom plate, bearing platform and foundation ring. This kind of independent expansion foundation can achieve better compressive bearing capacity in combination with appropriate foundation conditions, so it is often used in building column foundations. However, for wind power towers, the main force of the superstructure on the foundation is not the pressure but the bending moment. Therefore, the traditional independent expansion foundation has excess compressive capacity and insufficient bending resistance, resulting in a large waste of foundation design.
现有的风力发电塔独立扩展基础多采用变厚度悬挑板作为基础底板，由于基础平面图尺寸大，板的悬挑长度大，而且悬臂板受力后结构效应很大，故基础不经济，投资较大。而且现有的承压梁板式基础在梁和板之间的施工过程中钢筋绑扎、模板支撑非常麻烦，造成施工周期很长，相应的造价增加。The existing independent expansion foundations of wind power towers mostly use variable-thickness cantilevered slabs as the foundation floor. Due to the large size of the foundation plan, the length of the cantilevered slabs is large, and the structural effect of the cantilever slabs is large after being stressed, the foundation is uneconomical and the investment larger. Moreover, the existing pressure-bearing beam-slab foundations are very cumbersome in the construction process between the beam and the slab, and the formwork support is very troublesome, resulting in a long construction period and a corresponding increase in cost.
发明内容Contents of the invention
基于现有技术所存在的问题，本发明的目的是提供一种钢桁架结构的风机基础，其抗弯矩能力好，占地面积小，混凝土工程量少，施工方便，成本低。Based on the existing problems in the prior art, the object of the present invention is to provide a fan foundation with a steel truss structure, which has good moment resistance, small footprint, less concrete work, convenient construction and low cost.
本发明的目的是通过以下技术方案实现的：The purpose of the present invention is achieved through the following technical solutions:

每个钢桁架结构件对应固定连接在一组桁架预埋连接组件上，连接后的多个钢桁架结构件呈放射状分布设置在所述混凝土承台外周的所述混凝土基础底板上；Each steel truss structure is correspondingly fixedly connected to a group of truss pre-embedded connection components, and the connected multiple steel truss structures are radially distributed and arranged on the concrete foundation floor on the outer periphery of the concrete cap;
所述外圈连接钢结构件套设在所述多个钢桁架结构件外周，该外圈连接钢结构件分别与各钢桁架结构件的后端固定连接；The outer ring connecting steel structure is sleeved on the outer periphery of the plurality of steel truss structures, and the outer ring connecting steel structure is fixedly connected to the rear end of each steel truss structure;

通过在混凝土基础底板和混凝土承台上埋设桁架预埋连接组件，将多个钢桁架结构件分别固定连接在多组桁架预埋连接组件，并在各钢桁架结构件外周套设固定连接外圈连接钢结构件，形成一种预制钢桁架结构的风机基础，该风机基础由于基础与地基实际承压面积减小，基础环形受压面上的压应力增大了，可用于抵抗上部结构弯矩引起基础地面的拔力，从而减小基础底面积；用钢桁架结构作为主要的抗弯构件，且用放射状的钢桁架件高度围成风力发电塔塔筒的基础中心筒，以减少基础混凝土的工程量；将风力发电机与基础的连接由基础环改为预应力锚杆环组件。保证了塔筒与基础的刚性连接，减少了用钢量，同时也简化了这部分的施工。By embedding truss pre-embedded connection components on the concrete foundation floor and concrete cap, multiple steel truss structural members are fixedly connected to multiple groups of truss pre-embedded connection components, and a fixed connection outer ring is sleeved on the outer circumference of each steel truss structural member Connect the steel structural parts to form a prefabricated steel truss structure fan foundation. Since the actual pressure bearing area of the foundation and the foundation is reduced, the compressive stress on the annular pressure surface of the foundation increases, which can be used to resist the bending moment of the superstructure The pulling force of the foundation ground is caused, thereby reducing the area of the foundation bottom; the steel truss structure is used as the main bending member, and the height of the radial steel truss is used to enclose the foundation center tube of the wind power tower to reduce the foundation concrete Engineering quantity; the connection between the wind turbine and the foundation is changed from the foundation ring to the prestressed bolt ring assembly. It ensures the rigid connection between the tower and the foundation, reduces the amount of steel used, and simplifies the construction of this part at the same time.
