Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a novel MIC prefabricated component grouting sleeve positioning structure. Background Art

[0002] During the production process of MIC (modular integrated construction) components, due to special structural requirements, grouting sleeves need to be added to the bottom of the corresponding post-cast columns. This design is mainly to achieve upper and lower connections during the subsequent site installation process. However, due to the large overall structure of the MIC component, a large number of grouting sleeves are equipped at the bottom, and the position accuracy of the grouting sleeves is directly related to the success of the site installation, so the position accuracy of the grouting sleeves is extremely high.

[0003] The traditional method of positioning the grouting sleeve is mainly to open a hole in the panel and use a grouting sleeve plug to fix the grouting sleeve. However, this method has many problems when applied to MIC components. First, the efficiency of workers installing the grouting sleeve plug is low, which makes it difficult to adapt to large-scale and high-efficiency production needs. Secondly, due to various factors in the installation process, such as improper operation and material deformation, the position of the grouting sleeve often deviates and the accuracy is not high, thus affecting the installation efficiency and quality of the site. In addition, the diameter of the grouting sleeve usually has a variety of specifications such as 600mm, 800mm, 1000mm, 1200mm, etc. The traditional positioning method requires the preparation of a plug that matches the diameter of the grouting sleeve, which undoubtedly increases the material cost and management difficulty. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned background technical problems and to propose a novel MIC prefabricated component grouting sleeve positioning structure.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A novel MIC prefabricated component grouting sleeve positioning structure comprises a positioning cone, wherein the positioning cone comprises a top cover and a plurality of side plates, the ends of the plurality of side plates are rotatably connected to the top cover via rotating shafts, the plurality of side plates are equidistantly arranged along the side of the top cover, a connecting rod is vertically arranged at the bottom of the top cover, a sleeve is slidably sleeved on the connecting rod, the sleeve is rotatably connected to the plurality of side plates via a support rod, and a tension elastic member is further arranged between the top cover and the sleeve.

[0007] As a further solution of the present invention: the tension elastic member is a spring, and the spring is sleeved on the connecting rod.

[0008] As a further solution of the present invention: the spring is specifically a compression spring.

[0009] As a further solution of the present invention: an end of the side plate away from the top cover is bent inwardly to form an arc-shaped portion.

[0010] As a further solution of the present invention: one end of the support rod is rotatably connected to the side plate, and the other end of the support rod is rotatably connected to the collar.

[0011] As a further solution of the present invention: a hole is opened on the base, a nut is fixed on the base at the hole, the tail end of the connecting rod can pass through the hole, the positioning cone is detachably fixed to the base by the connecting rod and the nut, and the grouting sleeve is sleeved on the positioning cone fixed on the base.

[0012] As a further solution of the present invention: the upper part of the connecting rod is a bare rod, the collar can slide vertically on the bare rod, and the outer surface of the lower part of the connecting rod is provided with a thread matching with a nut.

[0013] As a further solution of the present invention: the top cover and the connecting rod are connected and fixed via a connecting portion.

[0014] As a further solution of the present invention: the positioning cone is in a cone shape, and the positioning cone is inverted and fixed on the base.

[0015] As a further solution of the present invention: the outer diameter of the positioning cone is smaller than the inner diameter of the grouting sleeve.

[0016] Beneficial effects of the present invention: Compared with the traditional grouting sleeve positioning method, the present invention does not need to use multiple plugs of different specifications for matching and installation, which greatly simplifies the construction process. At the same time, the adjustment and fixing of the positioning cone are simple and quick to operate, which can significantly improve the construction efficiency of workers and shorten the construction period. Reduce costs: Since the positioning structure of the present invention is universal and adjustable, there is no need to prepare special plugs for grouting sleeves of different diameters, thereby reducing the types and quantities of materials and reducing material costs. In addition, due to the improvement in construction efficiency, labor costs and time costs are also indirectly reduced. BRIEF DESCRIPTION OF THE DRAWINGS
