Embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings.
It is as shown in Figure 1 to allow press mechanism, by shell 1, the body of rod 2, ring washer 3, allow tabletting 4, cutting head 5,6 groups of closure Into.
Described shell 1 is the cylinder of the metal tape bottom plate with certain thickness and intensity, and its top is provided with screw thread, can used Closure 6 is closed.Cylinder bottom plate center is provided with circular hole, and the diameter in hole is slightly larger than the diameter of the body of rod 2, so that the body of rod 2 can be in circle Slided up and down in hole.Shell 1 has enough intensity, to ensure that it is small that anchor pole is deformed in loading process, can ignore.
The described body of rod 2 is common anchor pole in engineering, such as screw-thread steel, round steel, the selection of its diameter and material according to Depending on engineering design.
Described ring washer 3 is that with certain thickness annulus, its thickness is according to allowing depending on pressure, outside ring washer 3 Footpath is equal to or slightly less than the internal diameter of shell 1, and ring washer 3 can freely load in shell 1, by intensity high metal or other materials It is made, it is ensured that deform small allowing in the press mechanism course of work, can ignore.
Described allows tabletting 4 to be, with certain thickness annulus, to be made up of metal or other materials, and its external diameter is equal to or omited Less than the internal diameter of shell 1, tabletting 4 can be freely placed in shell 1.The internal diameter of tabletting 4 is allowed to be less than the internal diameter of ring washer 3.Allow Tabletting 4 is with allowing pressure pad circle to be stacked successively.In order to ensure to allow tabletting 4 have it is good allow pressure effect, can be set allowing in tabletting 4 Radial opening, in favor of the smooth development for allowing tabletting 4 to be deformed after being squeezed.
Described cutting head 5 is made up of the metal of high intensity, and its shape can be spheroidal, cylindricality, truncated cone-shaped or more The combination of shape.Its center is provided with screwed hole, in order to which the body of rod 2 is attached, and the peripheral diameter of cutting head 5, which is more than, allows pressure The internal diameter of piece 4, less than the internal diameter of ring washer 3.
Described closure 6 is, with certain thickness plectane, to be made up of metal or other materials, and periphery is provided with screw thread, It can be threadedly coupled with shell 1, sealing function is played to shell 1.The circular hole of two not insertions can be set on plectane, is easy to peace Dress.
In the case where being fully understood by roadway surrounding rock or slope deforming feature, determine allow press through in journey required for allow pressure Resistance and allow pressure displacement total amount, determine ring washer 3, allow thickness, internal diameter and the external diameter and quantity of tabletting 4, the body of rod 2 it is straight Footpath, the shape size of cutting head 5, the parameter such as the internal-and external diameter of shell 1 and height, these parameters and the strength of materials one with upper-part Rise to determine and allow pressure resistance.These parameters of flexible combination and the material of each part is flexibly chosen during design, it is possible to achieve to allowing pressure The control of resistance, can be designed as the resistance gradually increased, or the resistance being gradually reduced, or first increases and then decreases resistance, or First reduce resistance for increasing afterwards etc..
During installation, the body of rod 2 is passed through into the circular hole of the bottom of shell 1 first and the top of shell is stretched out, then by ring washer 3rd, allow tabletting 4 to stack successively and be inserted in the body of rod 2, be placed into shell 1, the height stacked slightly larger than allow pressure displacement total amount when, stop Only stack.Cutting head 5 and the body of rod 2 are attached by screw thread after fixing, the body of rod 2 is stretched to the bottom of shell 1, makes cutting head 5 push down it is uppermost in shell 1 allow tabletting 4, and cause cutting head 5 to be in the inside of shell 1.Closure 6 is screwed on shell 1 In the screw thread in portion, and closure 6 is pushed down cutting head 5, and make it that all parts are all compressed in shell 1.
Press mechanism is allowed to be directly placed into as anchoring body in pre-drilled anchor hole using what is combined, the body of rod 2 stretches out Rock And Soil Form anchor head.Press mechanism and the body of rod 2 will be allowed to be fixed by way of traditional construction method such as slip casing by pressure, anchor head is consolidated Determine mode and use the traditional approach such as such as anchor slab+bolt connection, or anchorage connection.
The utility model can control to allow the size of press mechanism by flexible design, and realization allows press mechanism and anchor hole size Between rapport, be allowed to not impact integral construction.
In order to avoid or reduce underground water may to allow press arrangement into erosion, can when allowing press mechanism to be assembled The internal voids of shell 1 are filled with vaseline or other materials.
In the utility model example press mechanism can be also placed on as anchoring body in the middle of anchor pole, or be placed on anchor Head position.
The utility model example is after construction in place, with the deformation of roadway surrounding rock or slope slide, allows press mechanism stress Gradually increase, stress reach it is designed allow after pressure resistance, cutting head 5, which starts shearing, allows tabletting 4.Tabletting 4 is allowed gradually to deform simultaneously Surrender.Tabletting 4 is allowed to provide after allow pressure when first, its part remained allows tabletting 4 to contact and open jointly with second Begin to provide resistance, now first allows sliding of the tabletting 4 to cutting head 5 to realize hysteresis, prevents cutting head 5 on country rock or side Slide bending first and allow after tabletting, impact, Jin Eryin suddenly due to lacking follow-up resistance under the traction of slope sliding force Play anchor pole to be broken or extract by large impact power, cause and collapse.Tabletting is allowed to provide after allow pressure when second, its is residual Staying part to allow tabletting to play with the 3rd again allows pressure to act on, by that analogy, and cutting head 5 allows between tabletting inside the shell 1 The shearing slip that row is more smoothed out, journey is pressed through it is achieved thereby that allowing.And in order to realize the shearing slip more smoothed out, cutting head is excellent Elect truncated cone-shaped as,
In summary, by the way that one kind is simple in construction, change is flexible allows press mechanism, the utility model is on roadway surrounding rock or side When large deformation occurs for slope, one kind can be provided and allow adjustable allow of pressure resistance to press windlass structure, this pressure windlass structure can be carried out with deformation Fully coordinate, meanwhile, can according to deformation characteristicses to allow pressure during allow pressure resistance size to be adjusted.
As described above, embodiment of the present utility model is described in detail, but as long as essentially without disengaging The characteristics of the utility model and effect, can there is many variations, and this is apparent to one skilled in the art , therefore, the example of these deformations is also integrally incorporated within protection domain of the present utility model.
