Description

Embedded diamond-shaped steel-reinforced concrete column foot anchor bolt fixing device

technical field

The utility model relates to a construction engineering facility, in particular to an embedded diamond-shaped steel-reinforced concrete column foot anchor bolt fixing device, which is simple in structure and easy to use, and can quickly and accurately complete the installation of diamond-shaped steel-reinforced concrete column foot anchor bolts. It is fixed and can be reused, saving construction materials.

Background technique

The column foot anchor bolt fixing devices used in the engineering construction mainly include: steel support frame, wooden cross and so on. The above devices are temporary measures and have their own shortcomings that are difficult to overcome: for example, the strength is not high, the error is large, the position adjustment is inconvenient, and the height and weather are limited, especially when the concrete is poured, the anchor bolts at the base of the column are prone to deviation. . However, in the current setting out of the diamond-shaped steel column position, the instrument cannot reach the bottom of the foundation, so the accuracy of vertical setting out cannot be guaranteed. The technology of the utility model adopts a reusable fixing device, only needs to stake out and locate the fixing device, and clarify its relative relationship with the axis, avoiding complex operations and positioning errors when the anchor bolt is staked out alone, and can be reused.

Contents of the invention

The purpose of this utility model is to propose an embedded diamond-shaped steel-reinforced concrete column foot anchor bolt fixing device, which is simple in structure, easy to use, can quickly and accurately complete the fixing of diamond-shaped steel-reinforced concrete column foot anchor bolts, and can be reused , Save construction materials.

In order to achieve the above purpose, the following technical solutions are adopted:

An embedded diamond-shaped steel-reinforced concrete column foot anchor bolt fixing device, including anchor bolts and positioning diamond-shaped plates, is characterized in that:

The size of the positioning diamond plate and the diaphragm of the anchor bolt fixing frame are the same, and the positions of the anchor bolt holes reserved on the diaphragm of the positioning diamond plate and the anchor bolt fixing frame are also the same. The positioning diamond plate and the anchor bolt fixing frame diaphragm are connected by anchor bolts Integrate, the vertical support steel plate fixes the positioning rhombic plate and the transverse diaphragm of the anchor bolt fixing frame by welding.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

The utility model overcomes the disadvantage of easy displacement of the traditional construction method, can realize the functions of extradition, limitation and precise positioning of the diamond-shaped steel bone column, and has a simple structure, convenient operation, fast construction, and can be used repeatedly, that is, the construction period is shortened. It also saves money and has strong practicability. It ensures the safety of operators during construction, improves construction efficiency, effectively ensures the positioning of the lower end of the diamond-shaped steel column, and then controls the construction quality and accuracy of the diamond-shaped steel column. . It not only effectively solves the technical problem of fast and accurate positioning of diamond-shaped steel columns, but also provides a reference for the innovation of steel structure hoisting and positioning technology.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing:

An embedded diamond-shaped steel-reinforced concrete column foot anchor bolt fixing device, comprising an anchor bolt 1 and a positioning diamond-shaped plate 2, characterized in that:

The size of the positioning rhombic plate 2 is the same as that of the diaphragm 3 of the anchor bolt fixing frame. The plate 3 is connected into one body through the anchor bolt 1, and the vertical support steel plate 4 fixes the positioning diamond plate 2 and the transverse diaphragm 3 of the anchor bolt fixing frame by welding.

As shown in the figure, the positioning of the column foot of the utility model includes an anchor bolt 1, a positioning rhombic plate 2, an anchor bolt fixing frame transverse partition 3 and a vertical support steel plate 4. The above-mentioned anchor bolt 1, positioning rhombic plate 2 and anchor bolt fixing frame diaphragm 3 are pre-assembled, and the center point of the column is first determined during construction, and the center point is precisely positioned by a total station and aligned with the center point of the adjacent column foot. Form a line, and extradition within the visual range of the surrounding and the distance not exceeding 1m, form two mutually perpendicular crossing lines, which are the anchor bolt positioning holes. On the positioning rhombus plate 2, first use white chalk to make two mutually perpendicular axes (that is, the pre-reserved anchor bolt holes). The line coincides to determine the base of the column. And the vertical support steel plate 4 is welded and anchored to the steel bar of the bottom plate according to the side of the transverse diaphragm 3, and the upper ends are respectively welded to the positioning rhombic plate 2 and the transverse diaphragm 3, and the horizontal direction is based on the discarded short steel bars on site. on the diaphragm 3.

Compared with the prior art, the utility model overcomes the traditional shortcoming of being easy to displace, and can realize extradition and precise positioning of the diamond-shaped steel-bone column. The utility model has the advantages of simple structure, rapid construction, reusability, strong practicability, and can well conform to the diamond-shaped steel-frame column constructed before, and can well ensure the construction quality and precision of the diamond-shaped steel-frame column.
