Projection about 25-30cm, space is smaller, and after connection anchor head is connected with suspender tension end HiAm anchorage, the space for leaving 5cm or so can be with
Meet suspension rod elongation, thus, it is necessary to force transmission rack avoids otic placode with being connected anchor head connection, and power transmission is carried out, so as to realize suspension rod
Tensioning of the anchorage on beam face.
The content of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, there is provided one kind be used for suspension rod ears it is board-like under
The force transmission rack structure of tensioning on anchor point beam face, the arrangement being engaged by groined type force transmission rack and connection anchor head, realizes ear
The avoidance of plate, realize tensioning of the suspension rod anchorage on beam face.
The utility model purpose is realized and completed by following technical scheme：
A kind of force transmission rack structure for tensioning on the board-like anchorage beam face of suspension rod ears, for realizing that suspension rod anchorage exists
Tensioning on beam face, the suspension rod periphery are provided with otic placode, and the both sides of the otic placode are fixedly connected with bracket, it is characterised in that：
The force transmission rack structure includes groined type force transmission rack, connection anchor head, and two are provided with the centre position of the groined type force transmission rack
Root support bar, it is described connection anchor head one end be fixedly supported upon on the support bar, it is described connection anchor head the other end with it is described
The stretching end HiAm anchorage connection of suspension rod, thrustor, the pushing tow dress are respectively arranged with the both sides of the groined type force transmission rack
The pushing tow face put is contacted in the bracket.
The otic placode passes through from the gap location between the groined type force transmission rack and the support bar.
The groined type force transmission rack is spliced to form by some shoulder pole girders, and the shoulder pole girder of at least side is arranged to detachable
Formula structure.
The thrustor is jack.
The utility model has the advantages that：The shortcomings that successfully overcoming tensioning below beam face, detachably, have installation it is simple,
The characteristics of recycling, a kind of easily method is provided for the tensioning of suspension rod anchorage, construction cost is greatlyd save, has
Huge engineering popularizing application prospect.

Embodiment
The utility model feature and other correlated characteristics are described in further detail by embodiment below in conjunction with accompanying drawing,
In order to the understanding of technical staff of the same trade：
As shown in figures 1 to 6, label 1-11 is expressed as in figure：Groined type force transmission rack 1, shoulder pole girder 2, connection anchor head 3, branch
Strut 4, otic placode 5, bracket 6, jack center 7, jack 8, the projection 9 that blocks water, beam face 10, suspension rod 11.
Embodiment：As shown in figure 1, it is used for the force transmission rack knot of tensioning on the board-like anchorage beam face of suspension rod ears in the present embodiment
Structure includes groined type force transmission rack 1 and connection anchor head 3, is fixedly installed two at the middle part of groined type force transmission rack 1 and is parallel to each other
Support bar 4, two support bars 4 are used for common fixed bearing connection anchor head 3 so that connection anchor head 3 by two support bars 4 with
Groined type force transmission rack 1 is connected to a fixed.
As seen in figures 3-6, the projection 9 that blocks water is provided with beam face 10.Otic placode is fixedly installed respectively in the both sides of suspension rod 11
5, it is welded with bracket 6 in the outside of otic placode 5.As shown in figure 1, two pieces of otic placodes 5 are respectively from support bar 4 and groined type force transmission rack
Gap location between 1 passes through, so as to realize the avoidance of otic placode 5.As shown in figure 3, it is fixedly supported upon the company on groined type force transmission rack 1
Composition HiAm anchorage connects between connecing the stretching end of anchor head 3 and suspension rod 11.It is fixedly installed respectively in the both sides of groined type force transmission rack 1
As the jack 8 of thrustor, the pushing tow face of jack 8 is contacted in the lower surface of bracket 6.Now, pressed when jack 8 presses
When power carries out pushing tow to jack 8, groined type force transmission rack 1 bears the counter-force of jack 8 and drives suspension rod 11 by connecting anchor head 3
Stretching end move down, so as to realize tensioning of the anchorage of suspension rod 11 on beam face 10.
In order to ensure the uniformity to the tensioning of suspension rod 11, with reference to shown in Fig. 2 and Fig. 3, the jack center of two jack 8
7 are arranged symmetrically in the center of bracket 6.With reference to shown in Fig. 1 and Fig. 3, connection anchor head 3 is in the center of groined type force transmission rack 1
On position, coordinate the jack 8 of both sides, realize the uniform tensioning of suspension rod 11, improve the uniformity and stability of the tensioning of suspension rod 11.
The present embodiment is in the specific implementation：Groined type force transmission rack 1 is the groined type knot being spliced to form by four shoulder pole girders 2
It is detachable connection structure between the shoulder pole girder of the connection corresponding with both sides of shoulder pole girder 2 of structure, wherein side so that the root shoulder pole
Beam 2 can be removed easily, consequently facilitating the repetition assembling of groined type force transmission rack 1.And the connection between remaining shoulder pole girder both can be with
It is arranged to be fixedly connected it can also be provided that detachable connection, Fast Installation can be easy to implement by being arranged to be fixedly connected, and can
Being detachably connected with then can convenience in transport.
Although the design to the utility model purpose and embodiment elaborate above example referring to the drawings,
But those skilled in the art will realize that in the case where limiting the precondition of scope without departing from claim, still may be used
