Description

Technical Field

[0001] This utility model relates to the field of electromechanical installation technology, specifically a fixing device for fire hydrant boxes based on concrete circular columns. Background Technology

[0002] Currently, circular concrete columns are widely used in public and civil buildings such as airports, train stations, and shopping malls, especially in large open spaces where fire hydrant boxes have no other walls or attachments for fixed installation and can only be installed on circular concrete columns.

[0003] Because the current design specifications do not include the practice of installing fire hydrant boxes on circular columns, the traditional installation methods in the industry are concrete or steel foundations for ground installation, steel straps for column mounting, or back-frame mounting. The concrete or steel foundation method is limited to modular fire cabinets, and small boxes require very tall concrete or steel foundations, resulting in an abrupt and unsightly overall appearance. The steel strap column mounting and back-frame methods have disadvantages such as high material consumption, complicated processing, multiple installation steps, and poor overall appearance. In addition, this method relies on the back plate of the fire hydrant box to bear the stress, resulting in poor stress conditions and easy deformation and damage under external forces.

By adjusting the position of the adjusting bolt 302 in the ear-shaped fixing member 301, and then adjusting the distance between the positioning frame 201 and the ear-shaped fixing member 301, the fixing unit 1 can be adjusted to fit snugly against the concrete column 5. This ensures that the connecting unit 2 between the fire hydrant box 4 and the concrete column 5 is not visible from the front or side views, resulting in a more harmonious and aesthetically pleasing design.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] This utility model discloses a fixing device for fire hydrant boxes based on concrete circular columns.

[0035] Example 1:

[0036] According to the appendix Figure 1-3 As shown, it includes:

[0037] Fixed unit 1;

[0038] Connecting unit 2 is disposed at both ends of fixed unit 1;

[0039] Adjustment unit 3 is located on the back of the corresponding connection unit 2;

[0040] Fire hydrant boxes 4 are installed between fixed units 1, and fire hydrant boxes 4 of different sizes are installed in conjunction with fixed units 1.

[0041] Fixed unit 1 includes:

[0042] The fixing bracket 101 is used to install the fire hydrant box 4;

[0043] The connecting frame 102 is fixedly connected to the fixing frame 101. The connecting frame 102 fits against the fixing frame 101 and limits the spacing of the fixing frame 101 under the action of the connecting frame 102.

[0044] The fixing bolt 103 is inserted into the connecting bracket 102 to limit the fitting of the connecting bracket 102. The distance between the two fixing brackets 101 is adjusted in conjunction with the connecting bracket 102. The fixing brackets 101 facilitate the installation of fire hydrant boxes 4 of different sizes.

[0045] The length of each side of the fixing bracket 101 is one or two centimeters shorter than the width of the fire hydrant box 4. The fixing device between the fire hydrant box and the column is not visible from the front of the fire hydrant box 4, making it more coordinated and aesthetically pleasing. Bolt holes are drilled six centimeters from the end of the fixing bracket 101. The size of the holes can be φ4, φ6, etc., mainly determined by the total weight of the fire hydrant box 4 and its internal components.

[0046] The mounting bracket 101 has a reserved thickness for the ear-shaped parts so that the fire hydrant box 4 can be installed in one go when it is fully clamped, without having to tighten the nuts again.

[0048] The ear-shaped fastener 301 is installed in the concrete column 5 by expansion bolts. The ear-shaped fastener 301 is made into an arc shape, and its curvature is the same as that of the concrete column 5. The side of the ear-shaped fastener 301 connected to the load-bearing edge angle steel needs to be beveled according to the overlapping angle. The fixing unit 1 is installed by adjusting unit 3 in conjunction with connecting unit 2, which makes the installation more convenient and quick, and uses less material, and meets the installation of various sizes of boxes.

[0049] The adjusting bolt 302 is threaded into the ear-shaped fixing part 301 and inserted into the positioning bracket 201. By adjusting the position of the adjusting bolt 302 in the ear-shaped fixing part 301, the distance between the positioning bracket 201 and the ear-shaped fixing part 301 can be adjusted to make the fixing unit 1 fit with the concrete column 5. This makes the connecting unit 2 between the fire hydrant box 4 and the concrete column 5 invisible from both the front and side views, resulting in a more harmonious and aesthetically pleasing appearance.

[0050] Example 2:

[0051] Connection unit 2 includes:

[0052] The positioning bracket 201 is attached to the end face of the fire hydrant box 4. The positioning bracket 201 is fixedly connected to the fire hydrant box 4 by bolts to ensure the stability of the fire hydrant box 4.

[0053] The connecting seat 202 is fixedly connected to the outer wall of the positioning frame 201;

[0054] The connecting bolt 203 is threaded onto the connecting seat 202 and inserted into the fixing frame 101. The fixing frame 101 is fixedly connected to the connecting seat 202 and the positioning frame 201 by the connecting bolt 203.

[0055] The positioning bracket 201 is fixed to the fire hydrant box 4 with M4 bolts to form a whole.
