Description
The technical field is as follows:
the utility model belongs to the technical field of the piping lane built-in fitting, what mainly related to is a pre-buried subassembly that utility tunnel used.
Background art:
the city total pipe gallery is also called as a common ditch, more than two municipal pipelines such as electric power, communication, gas, heat supply, water supply and drainage and the like are intensively paved in the pipe gallery tunnel, and a special overhaul port, a hoisting port and a detection system are arranged to implement intensive tunnel space of unified planning, design, construction and maintenance.
When concrete is poured on the side wall of the pipe gallery, embedded parts used for fixing the pipeline supporting platform need to be embedded, and in order to ensure that pipelines are correctly installed, the embedded parts are required to be accurate in position and consistent in depth during construction of the pipe gallery.
In order to increase the stability of the embedded parts, the existing pipe gallery embedded parts have two types, the first type is to weld the bent anchor bars on the anchor plate directly, but the anchor bars are often bent twice in the construction process, so that the anchor bars are in contact with the steel bars, and the anchor plate is easy to deform or generate displacement;
the second type is that the anchor bars and the anchor plate are connected by a spherical pin structure, the anchor bars can rotate on the anchor plate, the anchor bars and the steel bars are conveniently contacted and bound, the problem of secondary bending of the anchor bars is solved, however, when concrete is poured, the anchor bars are easily bent by smashing, and when the concrete is serious, the anchor bars can be separated from the spherical hinged support and lose the effect.
The invention content is as follows:
in order to overcome the defects, the invention provides a pre-buried assembly for an underground comprehensive pipe gallery.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides a pre-buried subassembly that utility tunnel used, includes anchor slab and the separable anchor bar with the anchor slab, one side of anchor slab is equipped with the recess, and the inside of anchor slab is equipped with the passageway, recess and passageway UNICOM, and the width of recess is less than the passageway, and vertical equidistant being equipped with a plurality of preformed grooves between recess and the passageway, preformed groove and passageway UNICOM, the tip of anchor bar is equipped with the anchor head, and the anchor head can slide in the passageway, and the anchor head can also hold in the preformed groove.
The channel does not extend through the entire anchor plate.
The preformed groove is obliquely arranged upwards, so that anchor bars are prevented from falling off.
And four threaded holes are formed in the anchor plate and are symmetrically distributed on two sides of the channel.
And a supporting piece is arranged between the anchor bars.
The support piece comprises a damping pin, connecting rods, a connecting pin and a sleeve, the sleeve is sleeved on the anchor rib and limited by a baffle on the anchor rib, one ends of the sleeve and the connecting rods are connected through the connecting pin, and the other ends of the two connecting rods are connected through the damping pin.
Due to the adoption of the technical scheme, the invention has the following advantages:
the utility model provides a pair of pre-buried subassembly that underground utility tunnel used, simple structure, and dowel and anchor slab are split type structure, also can install easily in narrow and small space, and in addition, the anchor head spanes in the preformed groove of anchor slab, even the dowel receives the impact of concrete also not worry to drop, can still be equipped with support piece between dowel and the dowel, guarantees that the dowel can not take place deformation in the pouring.

in the figure: 1. an anchor plate; 2. anchoring ribs; 3. an anchor head; 4. a channel; 5. reserving a groove; 6. a groove; 7. a threaded hole; 8. a sleeve; 9. a connecting rod; 10. a baffle plate; 11. a damper pin; 12. and (7) connecting pins.
The specific implementation mode is as follows:
the present invention will be explained in more detail by the following examples, which are intended to disclose all changes and modifications within the scope of the present invention, and the present invention is not limited to the following examples;
combine the figure a pre-buried subassembly that utility tunnel used, including anchor slab 1 and with anchor slab 1 separable anchor bar 2, one side of anchor slab 1 is equipped with recess 6, the inside of anchor slab 1 is equipped with passageway 4, recess 6 and passageway 4 UNICOM, and the width of recess 6 is less than passageway 4, vertical equidistant being equipped with a plurality of preformed grooves 5 between recess 6 and the passageway 4, preformed groove 5 and passageway 4 UNICOM, the tip of anchor bar 2 is equipped with anchor head 3, anchor head 3 can slide in passageway 4, anchor head 3 can also hold in preformed groove 5.
The channel 4 does not extend through the entire anchor plate 1.
The preformed groove 5 is obliquely arranged upwards to prevent the anchor bars from falling off.
Four threaded holes 7 are formed in the anchor plate 1, and the threaded holes 7 are symmetrically distributed on two sides of the channel 4.
And a supporting piece is arranged between the anchor bars 2.
The support piece comprises a damping pin 11, connecting rods 9, a connecting pin 12 and a sleeve 8, the sleeve 8 is sleeved on the anchor bar 2 and limited by a baffle 10 on the anchor bar 2, one ends of the sleeve 8 and the connecting rods 9 are connected through the connecting pin 12, and the other ends of the two connecting rods 9 are connected through the damping pin 11.
It can be seen from fig. 1 that the remaining anchor bars 2 of the anchor plate 1 are separable, which facilitates installation, because a plurality of steel reinforcement frameworks are arranged between the templates, the installation control is narrow, when in installation, the anchor plate 1 can be fixed at a designed position by matching the anchor plate 1 with the threaded holes 7 through bolts, then the anchor bars 2 are placed, the anchor bars 2 are in a T shape, the end parts of the anchor bars are anchor heads 3, the anchor heads 3 can slide downwards along the channel 4 and enter the preformed groove 5 after sliding to a proper position, because the preformed groove 5 is obliquely and upwards arranged, namely towards the inlet direction of the channel 4, the anchor heads 3 do not need to worry about sliding into the channel 4 again, the channel 4 does not penetrate through the anchor plate 1, so that only one inlet is provided, which can also prevent the risk that the anchor heads 2 fall off from the preformed groove 5, the rod parts of the anchor bars 2 extend out of the grooves 6, so that the anchor bars 2 can rotate perpendicular to the grooves 6, and selecting a proper angle, and binding the anchor bar 2 and the reinforcing steel bar.
Of course the anchor bar 2 can receive the impact when pouring the concrete, probably makes the ligature pine take off, perhaps anchor bar 2 is crooked, at this moment can set up the support frame between anchor bar 2, support piece includes damping pin 11, connecting rod 9, connecting pin 12 and sleeve pipe 8, and 8 covers of sleeve pipe are on anchor bar 2, and is spacing by separation blade 10 on anchor bar 2, and connecting pin 12 connection is passed through to sleeve pipe 8 and the one end of connecting rod 9, and the other end of two connecting rods 9 passes through damping pin 11 to be connected, after 2 ligatures of anchor bar, ligatures damping pin 11 and connecting rod 9 and reinforcing bar, and support piece just so can support stock 2 to resist the impact of concrete to it.
The details of the above are not described in detail since they are prior art.
