Abstract

The utility model relates to an anchor slab of an intermediate prestressed anchor, which can apply stress to prestressed ribs at both ends of a preformed groove of a prestressed building member. The utility model comprises a slab body and a plurality of taper holes arranged in the slab body, and the slab body is provided with a prestressed rib groove. The utility model has the advantages of small size and low production and matching cost. When the utility model is used, the section of the preformed groove of the building member can be reduced correspondingly, so as to reduce damage to the intensity of the building member.

Description

The centre adds the stress anchor slab

The utility model relates to the ground tackle that is used for the presstressed reinforcing steel stress application of building unit, and especially a kind of centre adds the anchor slab of stress ground tackle.

Above-mentioned centre adds the stress ground tackle and is meant in the preformed groove of prestressed architecture member, to the ground tackle of the presstressed reinforcing steel stress application at preformed groove two ends.In the prior art, the structure that the centre adds the stress ground tackle is to produce OVM, the HM type annular ground tackle of use at present as the applicant.Its anchor slab structure is to be respectively equipped with one group towards opposite taper hole in plate body.During use, the presstressed reinforcing steel at building unit preformed groove two ends is passed from the both sides of plate body respectively, and in presstressed reinforcing steel termination one side with the after-applied stress of intermediate plate clamping.This anchor slab needs supporting intermediate plate also more because taper hole is many, profile is big, and therefore, on the one hand, the cross section of the preformed groove of building unit is corresponding bigger, and is bigger to the intensity infringement of building unit; On the other hand, manufacturing and supporting cost are higher.

The purpose of this utility model provides that volume is little, manufacturing and the low centre of supporting cost add the stress anchor slab.

For achieving the above object, the scheme that the utility model adopts is: it includes plate body and a plurality of taper holes that are located in the plate body, is provided with the presstressed reinforcing steel groove on described plate body.

Above-mentioned taper hole is meant in use, is used to pass presstressed reinforcing steel, and the conical through-hole of intermediate plate is installed therein; The presstressed reinforcing steel groove is meant in use, is used for the groove that the presstressed reinforcing steel of walking around plate body is played the role of positioning.

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

1, profile is little.Because plate body is provided with the presstressed reinforcing steel groove, the presstressed reinforcing steel of an end can be in hanging over the presstressed reinforcing steel groove in the building unit preformed groove, only need the presstressed reinforcing steel of the other end in the building unit preformed groove is passed plate body, can implement to add the stress operation with the intermediate plate clamping, the comparable prior art of taper hole quantity in the plate body less half.Therefore, profile of the present utility model can be dwindled significantly, thereby also can correspondingly dwindle the cross section of building unit preformed groove in use, to reduce the intensity infringement to building unit.

2, manufacturing and supporting cost are low.Because few half and the corresponding supporting therewith in use intermediate plate of the comparable prior art of taper hole quantity also reduce half, therefore, can reduce manufacturing cost of the present utility model and the cost supporting with it significantly.

The utility model is described in further detail below in conjunction with the accompanying drawing example:

Fig. 1 is the front view of the utility model embodiment.

Fig. 2 is the left view of the utility model embodiment.

Fig. 3 is the vertical view of the utility model embodiment.

In Fig. 1, Fig. 2 and the example shown in Figure 3, the utility model includes plate body 1 and is located at eight taper holes 2 in the plate body, and the external surface of its plate body 1 is provided with the presstressed reinforcing steel groove 3 of four road spills.

The utility model embodiment in use, the presstressed reinforcing steel of an end can become the latch closure shape in the four road presstressed reinforcing steel grooves 3 that hang over plate body 1 in the building unit preformed groove, and the taper hole 2 that eight presstressed reinforcing steels of the other end in the building unit preformed groove are passed from a side of plate body 1 respectively, and use the intermediate plate clamping, just can implement to add stress at intermediate plate one end then to eight presstressed reinforcing steels.The effect of presstressed reinforcing steel groove 3 is positions that relative fixed is walked around the presstressed reinforcing steel of plate body 1.

Claims

1, a kind of centre adds the stress anchor slab, and it includes plate body (1) and is located at a plurality of taper holes (2) in the plate body (1), it is characterized in that: be provided with presstressed reinforcing steel groove (3) on described plate body (1).
