Description

A pre-embedded screw fixing device

technical field

The utility model relates to the field of engineering equipment, in particular to a fastening device, in particular to a pre-embedded screw fixing device.

Background technique

The construction process of hydraulic engineering usually involves pre-embedded screw construction, the positioning of the pre-embedded screw is not accurate, or in the process of pouring concrete, the pre-embedded screw is easily affected by various factors such as concrete impact, vibrating rod collision, steel cage deviation, etc. This leads to a positional deviation, which is so large that the upper part cannot be installed.

The traditional construction method is to use manual positioning, which is easy to cause deviations. Rework to deal with the excessive deviation of the pre-embedded screw is extremely labor-intensive and time-consuming. When the deviation is serious, it may even be necessary to remove the foundation and re-construct. Especially when multiple embedded screws form a fixed unit, and multiple fixed units are combined to fix the upper component, the precise positioning and fixing measures of the embedded screw are particularly important. Deviation of a single embedded screw will lead to the failure of all embedded screws. The situation of rework processing; At the same time, the temporary installation of fixtures wastes a lot of manpower and financial resources, so there is an urgent need for a pre-embedded construction fixture.

In order to achieve the above object, the utility model adopts the following technical scheme: a pre-embedded screw fixing device, including a screw, a positioning plate and a fixing bracket, the positioning plate is provided with a grouting hole and a screw positioning hole, and the screw positioning hole Cooperate and connect with the screw rod; the fixed bracket includes a support plate and a support column, the support column is installed on the bottom surface of the support plate and fixedly connected, a groove is provided on the support plate, the fixed bracket and the positioning plate are connected by a screw rod and provided with Adjustment device.

The middle part of the above-mentioned positioning plate is provided with a positioning block extending laterally around the middle, and the positioning block is provided with a tip for aligning the engineering positioning ink line.

The above-mentioned adjusting device includes a nut and a washer, and the nut is installed above the fixing bracket and below the positioning plate with a washer between them.

The groove width as mentioned above is 1mm-5mm larger than the screw diameter.

As mentioned above, a handle is provided on the positioning plate.

The positioning plate as described above has a rectangular shape as a whole.

The fixing bracket as mentioned above is L-shaped as a whole.

Beneficiality of the utility model:

Compared with the traditional pre-embedded screw fixing device, the utility model can effectively improve the installation efficiency through the four screw positioning holes provided on the positioning plate. At the same time, a fixing bracket is provided, and the position is adjusted through the groove and the positioning block to realize high-precision positioning. Avoid rework caused by fixed deviations.

detailed description

With reference to the accompanying drawings, a further detailed description of a pre-embedded screw fixing device of the present invention is made,

Embodiment 1, a pre-embedded screw fixing device, including a screw 3, a positioning plate 1 and a fixing bracket 2, the positioning plate 1 is provided with a grouting hole 102 and a screw positioning hole, and the screw positioning hole is set on the positioning plate The four corners are connected with the screw rod 3; the fixed bracket 2 includes a support plate 202 and a support column 203, the support column 203 is installed on the bottom surface of the support plate 202 and fixedly connected, and the support plate 202 is provided with a groove 201 , the fixed bracket 2 and the positioning plate 1 are connected by a screw 3 and an adjusting device 4 is provided.

A positioning block 101 is provided laterally extending around the middle of the positioning plate 1, and the positioning block 101 is provided with a tip for aligning engineering positioning ink lines.

The adjusting device 4 includes a nut and a washer, and the nut is installed above the fixing bracket 2 and below the positioning plate 1 with a washer between them.

The width of the groove 201 is 1mm-5mm larger than the diameter of the screw rod 3 .

As a preferred solution of the utility model, the width of the groove 201 is 2mm larger than the diameter of the screw rod 3, which is convenient for adjusting the positions of the fixing bracket 2 and the screw rod 3 so that the support column 203 fits the construction work surface.

As the utility model positioning plate 1 is provided with a handle 5 .

As a preferred solution of the utility model, the positioning plate 1 is integrally shaped into a rectangle.

The specific use process of the utility model: firstly, locate the midpoint of the rack at both ends of each row of trolley line brackets, and use these two points to pop up a long ink line on the working surface, and this ink line is used as the center of the positioning block 101 Align to baseline.
