Description

A kind of draw-in groove fixes the anchor plate of reducer union

Technical field

The utility model relates to the anchor plate of prestress wire, particularly be the anchor plate that a kind of draw-in groove fixes reducer union.

Background technology

In recent years along with the development of building trade, prestressed concrete is promoted gradually, and compared with conventional steel bar concrete, it is high that prestressed concrete has intensity, save the advantages such as material, now advanced technology is vacuum grouting post stressed concrete technology.Its feature is first built-in metal or plastic film capicitor, is connected on anchor plate by bellows by reducer union, and carries out encapsulation process, and then monobloc cast concrete.After concrete reaches some strength, tractive prestress wire in pre-buried pipeline, with anchor plate, prestress wire is fixed on concrete component, finally vacuumize at pipeline one end vacuum pump, it is made to produce the vacuum of-0.1Mpa, with grout pump, special cement is poured into from the pipeline other end again, until be full of pipeline.These connectors such as pre-buried corrugated conduit and anchor plate not only need to provide protective barrier for prestress wire, also need higher sealing to ensure the quality of vacuum grouting.

The large end external diameter of reducer union of present pre-buried bellows is less than the internal diameter of anchor plate, and the large end of reducer union can directly be inserted in anchor plate, and then adopts binding to be fixedly connected with the mode of smearing fluid sealant around.This method of attachment is owing to can not bear pulling force between reducer union and anchor plate, so be easy to the sealing destroying junction when construction is vibrated at the scene, there is fluid sealant cracking, the phenomenon that reducer union is deviate from from anchor plate or leaked gas, affects compactness and the plumpness of vacuum prestressed pore passage grouting.

Summary of the invention

The purpose of this utility model is the defect overcoming prior art, provide a kind of easy and simple to handle, bonding strength is high and a kind of draw-in groove of good seal performance fixes the anchor plate of reducer union.

The technical scheme solved the problems of the technologies described above is: a kind of draw-in groove fixes the anchor plate of reducer union, and described anchor plate comprises anchor plate pipe and is arranged on the flange of anchor plate pipe one end; Flange end face is provided with: be greater than the locating slot of anchor plate pipe orifice, multiple connecting hole and a grout hole; A port of described grout hole is at flange end face, and another port of grout hole is on anchor plate pipe orifice sidewall; Anchor plate pipe orifice sidewall is also provided with the groove of the reducer union that is locked.

Preferred version is: the groove on described anchor plate pipe orifice sidewall comprises: two axial notches and two radial grooves; Two axial notch structure same positions are relatively all axially disposed within anchor plate pipe orifice sidewall along anchor plate pipe; Described two radial groove structure same positions are relatively all along anchor plate caliber to be arranged on anchor plate pipe orifice sidewall and to be communicated with described radial groove respectively; The reducer union outer sliding tube of described anchor plate pipe orifice and reducer union front end is joined; Described axial notch and radial groove are joined with two fixture blocks of reducer union outer tube projection are sliding respectively.

Preferred version is: between the flange back side and anchor plate pipe outer rim, be arranged at intervals with multiple muscle; Multiple muscle comprises large muscle and little muscle.

The utility model beneficial effect is:

1, the utility model adopts the groove on anchor plate to clamp the fixture block be fixedly connected with in reducer union, thus connects anchor plate and reducer union, and bonding strength is higher, easy and simple to handle.

2, the utility model anchor plate and reducer union adopt groove to be connected with fixture block, and can bear axial force, the reducer union avoiding appearance in construction is vibrated is deviate from from anchor plate, or the scene such as fluid sealant cracking, and sealing effectiveness is more reliable.

3, the utility model structural strength is high, easy to process, and suit large area to popularize use.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model embodiment is further illustrated.

As shown in the figure, the anchor plate 1 that the utility model provides a kind of draw-in groove to fix reducer union, described anchor plate 1 comprises anchor plate pipe 1c and is arranged on the flange 1d of anchor plate pipe 1c one end.

Flange 1d end face is provided with: be greater than the locating slot 1g of anchor plate pipe 1c endoporus, multiple connecting hole 1e and grout hole 1h.

A port of described grout hole 1h is at flange 1d end face, and another port of grout hole 1h is on anchor plate pipe 1c endoporus sidewall; Anchor plate pipe 1c endoporus sidewall is also provided with the groove of the reducer union 2 that is locked.

Groove on described anchor plate pipe 1c endoporus sidewall comprises: two axial notch 1a and two radial groove 1b; Two axial notch 1a structure same positions are relatively all axially disposed within anchor plate pipe 1c endoporus sidewall along anchor plate pipe 1c; Described two radial groove 1b structure same positions to be relatively all arranged on anchor plate pipe 1c endoporus sidewall along anchor plate pipe 1c radial direction and to be communicated with described radial groove 1b respectively.

The reducer union outer tube 2b of described anchor plate pipe 1c endoporus and reducer union 2 front end is sliding to be joined; Described axial notch 1a and radial groove 1b joins with two fixture block 2a of reducer union outer tube 2b projection are sliding respectively.

The flange 1d back side and anchor plate pipe 1c outer rim are provided with multiple large muscle 1f and multiple little muscle 1k; Between large muscle 1f and little muscle 1k, interval is arranged.Be used for strengthening the bulk strength of anchor plate 1, little muscle 1k is triangle gusset.

In particular, the locating slot 1g be arranged on flange 1d end face is used to anchor plate 1 to be fixed on concrete blinding; The multiple connecting hole 1e be arranged on flange 1d end face are used for placement work ground tackle; The entrance being arranged on the grout hole 1h on flange 1d end face, at flange 1d end face, exports the inside at anchor plate pipe 1c, and grout hole 1h is used for being poured in pre-buried corrugated conduit by special cement, until be full of.

As shown in Figure 2, Figure 3 and Figure 4, the reducer union 2b outer tube of reducer union 2 front end there are two fixture block 2a, the external diameter of reducer union outer tube 2b will be slightly less than the diameter of bore of anchor plate pipe 1c, anchor plate pipe 1c endoporus there is two axial notch 1a and two radial groove 1b, two fixture block 2a axially groove 1a move inward, after arriving radial groove 1b, fixture block 2a is along being rotated counterclockwise certain angle, under the restriction of radial groove 1b, fixture block 2a cannot in axial direction move, and reducer union 2 is fixed in anchor plate 1.

Encapsulation process adopts and spreads fluid sealant in reducer union outer tube 2b outer ring, and after being inserted into anchor plate pipe 1c endoporus, bonding is fixing.

Below use procedure is described:

As shown in Figure 2, after fluid sealant is spread in reducer union outer tube 2b outer ring, two fixture block 2a are aimed at axial notch 1a, and inwardly insert, after reaching radial groove 1b place, along being rotated counterclockwise certain angle, under the restriction of radial groove 1b, fixture block 2a cannot in axial direction move, thus fixing reducer union 2 and anchor plate 1, sealing relies on the fluid sealant of outer ring to be bonded and sealed.
