Description

Foundation bolt pre-buried structure Technical Field The utility model relates to the field of building construction, in particular to an anchor bolt pre-embedding structure. Background Foundation bolts are an important construction element for installing steel or mechanical elements such as steel columns into concrete foundations. The pre-buried installation accuracy of the foundation bolts directly influences the installation quality of connecting members, so that the problem of how to fix the foundation bolts before foundation concrete pouring becomes a key problem of pre-buried foundation bolts. The embedding of the foundation bolts is usually carried out after binding of the foundation reinforcement and before concrete pouring. However, in the pouring and vibrating process of the foundation concrete, the pre-embedded anchor bolts are easy to move and deviate, which can adversely affect the installation accuracy of subsequent components. Therefore, reasonable and advanced construction technology and tooling must be adopted to ensure the pre-burying precision of the foundation bolts. In steel structure plant foundation structures, it is common for the foundation to be an independent foundation under the column. For the condition that the foundation reinforcing steel bars are arranged below the corresponding positions of the steel columns, the foundation bolts can be fixed through welding with the foundation non-stressed reinforcing steel bars. However, when the steel bars are not arranged below the corresponding positions of the steel columns on the independent foundations, the lower ends of the embedded foundation bolts are in a suspended state, and special foundation bolt embedded fixing support tools are required to be arranged to ensure the reliable fixing of the embedded foundation bolts. There are some limitations to the anchor bolt-fixing bracket tooling currently available on the market. Firstly, most of the tools are integral fixed supports, and the tools cannot be flexibly adjusted and assembled according to the basic height. This results in the need to make tooling of multiple gauges, which is detrimental to quick installation on site. Secondly, the existing anchor bolt pre-embedding fixing measure is mainly suitable for conventional D6 mm-D30 mm anchor bolts. For large anchor bolts with the diameter of D45-D90 mm, the length and the weight of the large anchor bolts are multiplied, and the large anchor bolts cannot be reliably fixed by the existing embedded fixing measures, so that the embedded installation accuracy of the large anchor bolts cannot be guaranteed. These problems seriously affect the efficiency and accuracy of anchor bolt embedding, especially when dealing with large anchor bolts. Therefore, a novel foundation bolt pre-embedding structure is needed to meet the following requirements simultaneously, the stable installation of the foundation bolt at a set position is guaranteed, the foundation bolt pre-embedding structure is flexibly suitable for installation of different foundation heights, the construction stability and the installation precision of a large-scale foundation bolt can be guaranteed, the problems in the prior art are effectively solved, the precision and the efficiency of the foundation bolt pre-embedding are improved, and therefore more reliable foundation support is provided for subsequent building construction. Disclosure of utility model Therefore, the utility model aims to overcome the defects in the prior art, provide the anchor bolt embedded structure, ensure the stable installation of the anchor bolt at the set position, be flexibly applicable to the installation of different foundation heights, and especially ensure the construction stability of the large anchor bolt and the installation precision of the anchor bolt. The foundation bolt embedded structure comprises foundation bolts arranged in an embedded region of a construction foundation, a fixed support arranged in the embedded region, wherein the height of the fixed support can be controlled to be adjusted, the foundation bolts are supported at a set position of the embedded region by the fixed support, and the foundation bolt embedded structure further comprises a limiting assembly arranged at the top of the construction foundation, and the limiting assembly is used for limiting the foundation bolts to a preset position of the construction foundation. Further, the foundation bolts comprise a plurality of foundation bolts arranged in the embedded area, the foundation bolts are arranged at preset positions corresponding to the foundation bolts to form a group of foundation bolt groups, and the foundation bolts in the group of foundation bolts are parallel to each other. Further, spacing subassembly includes the locating plate, set up on the locating plate with a plurality of locating hole that the rag bolt quantity is unanimous in a set of rag bolt crowd, every rag bolt corresponds wears to locate a lo
