Description

Technical Field

[0001] The utility model relates to the technical field of concrete structure construction, in particular to a template for reserved bolt holes in a foundation of large-volume concrete equipment. Background Art

[0002] In the field of civil engineering, especially in the field of building structures, the foundation construction of large equipment is an important task. These equipment usually need to be fixed to the concrete foundation by connection to ensure the stability of the installation, so they are often fixed by setting embedded bolts. In the previous construction process, some solutions are to set embedded bolts at the connection position and assist in fixing, and then fix them in one step after pouring. This method has the problems of low construction accuracy, difficulty in later connection, and inconvenient maintenance after damage.

[0003] In order to improve the setting accuracy of embedded bolts, it was later proposed to set embedded bolt holes. After the embedded bolt holes are formed, the embedded bolts can be set. This can make the construction accuracy higher, and the setting position of the embedded bolts can be adjusted according to the actual installation. The installation accuracy is higher and many changes in the installation process are avoided. However, there are some problems in the construction of reserved embedded bolt holes by pouring. For example, the reserved bolt holes of large-volume concrete equipment are deep, and it is difficult to remove the templates in the later stage of construction using ordinary templates, and the construction quality is difficult to guarantee. Specifically, it is manifested as follows: First, traditional wooden templates and plastic templates are prone to deformation during concrete pouring, resulting in deviations in the position and size of the reserved bolt holes, affecting the installation and use of the equipment. Secondly, although metal templates have good strength and stability, they need to be customized according to the size and depth of the reserved bolt holes of the equipment. This not only increases the complexity and cost of construction, but also takes a long time to replace the template, affecting the construction efficiency.

[0004] It can be seen that the current construction of embedded bolt holes still has room for improvement, and adjustments and optimizations should be made to improve the convenience of construction, ensure the accuracy and quality of construction, and reduce construction costs. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes a template for reserved bolt holes in the foundation of large-volume concrete equipment. After the pre-embedded bolt holes are constructed through the template, there is no need to remove the template, which reduces the tedious operations of subsequent construction and can also ensure the accuracy and quality of construction.

[0006] In order to achieve the above purpose, the bolt hole template disclosed in the utility model can adopt the following technical solutions:

[0007] The bolt hole template for the foundation of large-volume concrete equipment includes a plurality of longitudinally arranged template reinforcements. Adjacent template reinforcements are connected and stabilized by transverse connecting structures. The transverse connecting structures are arranged at intervals along the extension direction of the template reinforcements, and a plurality of diagonal bracing structures are arranged between the transverse connecting structures to form a template cage. The outer side of the template cage is covered with a plurality of dense mesh layers, and the diameter of the through holes of the dense mesh layers gradually increases from the inside to the outside.

[0008] The above-disclosed reserved bolt hole template forms a template cage and fixes it at a predetermined position, so that a relatively independent space is formed in the template cage under the wrapping and isolation of the dense mesh layer, namely the reserved bolt hole; when pouring, the external concrete fluid is isolated by the dense mesh layer and cannot enter the internal space of the template cage until a complete reserved bolt hole is formed after pouring and molding, and the dense mesh layer can maintain a uniform receiving surface under the pressure of the concrete material without stress deformation, so the pouring quality can meet the installation requirements of the embedded bolts; at the same time, the template cage and the dense mesh layer can be used as auxiliary results for the positioning and fixing of the embedded bolts, without the need for dismantling, thereby improving the efficiency and convenience of construction as a whole.

[0009] Furthermore, in the present invention, the transverse connection structure can be constructed in a variety of forms, which are not limited to a single form. Here, an optimization is made and one of the feasible options is proposed: the transverse connection structure includes a polygonal frame and a circular frame. The transverse connection structure is located outside the template ribs and is fixedly connected to the template ribs. The transverse connection structure is evenly spaced along the height direction of the template ribs. When such a solution is adopted, the transverse connection structure is set and selected according to the number of template ribs and the hole forming requirements. For example, the device can be constructed as a circular frame, or a square frame, etc.

[0010] Furthermore, the diagonal bracing structure is used to maintain the stability of the formwork cage, and it can adopt a variety of solutions, which are not limited to the only one. Here, we optimize and propose one feasible option: the diagonal bracing structure includes a diagonal bracing arm, the upper end of the diagonal bracing arm is connected and fixed to the upper transverse connecting structure, and the lower end of the diagonal bracing arm is connected and fixed to the lower transverse connecting structure. When such a solution is adopted, the diagonal bracing arm and the transverse connecting structure can both be made of round steel with equal diameters.

[0011] Furthermore, in order to make the structure of the formwork cage more stable, an optimization is made here and one of the feasible options is proposed: the connection between the transverse connection structure and the formwork reinforcement forms a connection node, and the upper and lower ends of the oblique support arm are connected to the connection node. When such a solution is adopted, the upper and lower ends of the oblique support arm can be fixed to the transverse connection structure by welding; in some solutions, they can also be fixed by binding.

[0012] Furthermore, in order to form a better embedded bolt hole and reduce the convexity of the inner wall of the embedded bolt hole, the structure of the oblique support arm is optimized and one of the feasible options is proposed: after the oblique support arm is connected and fixed, the outer contour of the oblique support arm and the transverse connection structure remain coplanar. When such a solution is adopted, the outer side surface of the entire template cage is uniform, and the uniformity of the side wall of the entire template cage can be improved by setting a sufficient number of oblique support arms, thereby finally forming a uniform hole wall.

[0013] Furthermore, in the present invention, the dense mesh layer is used to prevent the concrete fluid from entering the reserved bolt hole. Here, an optimization is made and one feasible option is proposed: the number of the dense mesh layers is at least three, and the dense mesh layers are made of metal mesh. When such a solution is adopted, the dense mesh layer is connected and fixed to multiple points of the template reinforcement, and / or the transverse connection structure, and / or the diagonal bracing structure.

[0014] Furthermore, in the present invention, the arrangement of the dense mesh layer is not limited to a single one, and an optimization is made here and one feasible option is proposed: the dense mesh layer wraps the formwork cage to form a joint, and the joints between adjacent dense mesh layers are staggered by at least 30° on the side surface. When such a solution is adopted, the joints are staggered with the positions of the formwork ribs.

[0015] Furthermore, the dense mesh layer includes an inner dense mesh, a middle dense mesh and an outer dense mesh, and the mesh count of the inner dense mesh is greater than or equal to 200. In some other schemes, the mesh counts of the inner dense mesh, the middle dense mesh and the outer dense mesh can be adjusted according to actual needs.

[0016] Furthermore, in order to help fix the formwork cage, the lower end of the formwork reinforcement is adjusted, and an optimization is performed here and one of the feasible options is proposed: the lower end of the formwork reinforcement forms a pointed end.

[0017] Furthermore, in order to better fix the transverse connection structure, an optimization is made here and one of the feasible options is proposed: uniform concave and convex patterns are formed on the template ribs to cooperate in maintaining the relative height of the transverse connection structure. When such a solution is adopted, the concave and convex patterns are used to engage the transverse connection structure and limit the transverse connection structure from sliding down along the template ribs.

[0018] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0019] The utility model forms a casting template for embedded bolt holes, blocks concrete from entering the inner space of the bolt holes by a dense mesh layer, and withstands uniform extrusion force to form a more regular embedded hole wall. After casting and forming, there is no need to dismantle the template, thereby greatly improving the efficiency and quality of casting construction. BRIEF DESCRIPTION OF THE DRAWINGS
