Description

Technical Field

[0001] This utility model relates to the field of pre-embedded bolt fixing of precast components, specifically a pre-embedded bolt fixing structure for precast components. Background Technology

[0002] The emergence of prefabricated modular buildings in my country is of great significance. Under the current circumstances, the characteristics of prefabricated buildings, such as prefabricated steel structures and prefabricated concrete structures, are conducive to the development of new energy-saving and environmentally friendly industries, to improving the safety level of the construction industry, and to resolving problems such as overcapacity.

[0003] Given the current state of construction development, the traditional construction industry faces problems such as outdated production methods and low labor quality. Construction industrialization, as a new production method, is receiving increasing attention. The development of prefabricated buildings can bring high-standard construction speed and quality assurance, thereby driving the development of the construction industry.

[0004] In current construction, precast components are widely used as a representative of prefabricated buildings. During the installation of precast components, bolts are often embedded within the components to connect them to the cast-in-place structure. In actual construction, because all bolts are independently installed, the installation and fixing of these embedded bolts becomes a major challenge. Traditional methods either involve pre-drilling holes at the bolt locations and then placing the bolts later, which does not meet design requirements, or binding the bolts to the reinforcing steel bars of the component, which is not secure enough and their position cannot be guaranteed, making it easy for the bolts to shift during concrete pouring.

[0005] Therefore, it is necessary to develop an independent pre-embedded bolt fixing structure on prefabricated components. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by designing an independent pre-embedded bolt fixing structure for prefabricated components, thereby solving the construction problem of the inability to install and fix vertical pre-embedded bolts.

[0007] To achieve the above objectives, this utility model provides an independent pre-embedded bolt fixing structure for prefabricated components, employing the following technical solution: a template, wherein the template has a through hole at the position of the axial projection of the pre-embedded bolt, a fastening screw passes through the through hole, a connecting sleeve is connected to one side of the fastening screw and the pre-embedded bolt is connected to the other side of the connecting sleeve, a pad is provided on the outside of the template and a nut is provided on the outside of the pad, the nut is tightened to ensure that the bottom of the connecting sleeve abuts against the template, thereby ensuring that the position of the pre-embedded bolt is fixed.

[0008] Furthermore, the diameter of the pre-embedded bolt is M18, the inner diameter of the connecting sleeve is M18, the shape of the pad is a 100mm square with a thickness of 10mm, and the diameter of the fastening screw is M18.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention is simple, convenient and quick to operate on site, ensuring that the position of the pre-embedded bolts does not shift during the concrete pouring process and that the position of the pre-embedded bolts is accurate after the pouring is completed. Attached Figure Description

[0013] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0014] In the description of this utility model, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1As shown, this utility model is an independent pre-embedded bolt fixing structure on a precast component, comprising: a template 6, wherein the template 6 is provided with a through hole at the position of the axial projection of the pre-embedded bolt 1, a fastening screw 4 is provided through the through hole, a connecting sleeve 2 is connected to one side of the fastening screw 4 and the pre-embedded bolt 1 is connected to the other side of the connecting sleeve 2, a pad 3 is provided on the outside of the template 6 and a nut 5 is provided on the outside of the pad 3, and the nut 5 is tightened to ensure that the bottom of the connecting sleeve 2 is pressed against the template 6, thereby ensuring that the position of the pre-embedded bolt 1 is fixed.

[0017] When using this method of fixing with pre-embedded bolts 1, the lower part of the pre-embedded bolt 1 is screwed into the connecting sleeve 2, and the position of the connecting sleeve 2 coincides with the position of the pre-embedded bolt 1. A hole is drilled on the template 6 at the position of the pre-embedded bolt 1, and the hole size is the same as the size of the fastening screw 4. Before pouring concrete 7, the lower part of the fastening screw 4 is screwed into the lower part of the connecting sleeve 2, the pad 3 is installed, and the nut 5 is tightened to fix it. Then the concrete 7 is poured. When the concrete 7 reaches the level where the formwork can be removed, the nut 5 is unscrewed, and the pad 3 and template 6 are removed in sequence. This reinforcement method is convenient and quick to operate. The position of the pre-embedded bolt 1 does not shift during the concrete pouring process, and the position of the pre-embedded bolt 1 is accurate after the pouring is completed.

[0018] In one specific embodiment, the pre-embedded bolt 1 has a diameter of M18, the inner diameter of the connecting sleeve 2 is M18, the pad 3 is a 100mm square with a thickness of 10mm, and the fastening screw 4 has a diameter of M18.
