Abstract

The utility model relates to an embedded channel and particularly relates to a toothed embedded channel, so as to solve the technical problems existing in the prior art under the condition of ensuring equipment to be in good installation condition. The toothed embedded channel is used and installed in match with a T-type bolt. During the installation period, drilling and matched drilling are not needed. As the channel is toothed, 360-DEG panoramic installation can be realized, and heavy torque bearing of the equipment can be ensured. The toothed embedded channel comprises a hollow cuboid; the bottom end surface of the hollow cuboid and the top end surface of the hollow cuboid are opened; the middle region of the end surface at one side of the hollow cuboid is opened, and the opening extends from the top end of the end surface at the side to the bottom end of the end surface at the side; side end surfaces, provided with openings, of the hollow cuboid, are provided with continuous racks; the racks are sequentially arranged along the side end surfaces with openings; and the tooth top of each rack is parallel with the cross section parallel with the bottom end surface. The toothed embedded channel can be applied to the field of embedded channel design.

Description

A kind of toothed pre-buried channel flow

Technical field

The utility model is related to a kind of pre-buried channel flow, more particularly, to a kind of toothed pre-buried channel flow.

Background technology

Equipment is installed above current base station, mostly site operation drilling, the fracture of capital construction concrete reinforcing steel is easily caused in boring procedure, and manually borehole throw is larger, one equipment mounting hole site is often by repeatedly drilling, it is very big to the infringement of capital construction concrete, and loosening is installed because easily causing equipment after repeatedly punching, influence follow-up various kinds of equipment normally to use.Existing pre-buried technology applies the T-bolt in equipment right angle setting easily to slide, and influence equipment is used.

Pay attention to capital construction in the construction such as present room body, railway tunnel, pay attention to equipment purchase link, it is substantially all to despise and ignores equipment installation project technique, because extensive in construction work, there are mistakes and omissions when causing equipment to be installed with original design, cause more design alteration, because various design alterations ultimately result in heavy damage of the mounting process to civil engineering structure of element of installation, cause engineering construction service life to be had a greatly reduced quality.

Utility model content

Technical problem to be solved in the utility model is：The problem of existing for prior art, in the case where ensureing that equipment installation is intact, designs the toothed pre-buried channel flow of a class, supporting T-bolt is using installing, and installation period zero drills, and zero with brill, due to conduit band tooth, 360 ° of panoramas can be achieved and install, can guarantee that equipment gravitational moment is born.

The technical solution adopted in the utility model is as follows：

A kind of toothed pre-buried channel flow includes hollow cuboid, the hollow cuboid bottom face, hollow cuboid top end face are opening, the side end face intermediate region opening of hollow cuboid one, the opening is along this side end face top to this side end face bottom, the hollow cuboid sets the side end face of opening to be provided with continuous tooth bar, and the tooth bar is arranged in order along opening side end face；The tooth top of each tooth bar is parallel with the cross section parallel to bottom face.

The profile angle α of the tooth bar is 70 ° -80 °.

The α is 75 °.

The height H of the tooth bar is 2mm to 3mm.

The height H of the tooth bar is 2.5mm.

The opposing end surface both ends of the surface formation arc surface adjacent thereto of the side end face for being provided with opening, the arc radius r is 2mm to 3mm.

The arc radius r is 2.5mm.

The hollow cuboid material is Q235B.

In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are:

1）Tooth bar is set so that can be realized 360 ° of panorama installations in installation process, effectively be reduced because of additional installed part derived from setting angle.

2）The tooth height of this high scope of tooth is set, and advantage is that, by many experiments, this scope tooth height can be maximized on the premise of connection anti-shearing force is ensured to be made to engage reliability between T-bolt and tooth.

3）Open end and adjacent face are set to arc-shaped, R2.5 roundings enable conduit maximized increase stretching resistance when by vertical stress.

4）Attempted by multiple material, be used as rolling steel billet from Q235B steel, it is ensured that strength and toughness, special C-shaped conduit is rolled using special roll.
