Detailed description of the invention
Referring to figs. 1 through Fig. 4, an embodiment of the flexible joint parts that the present invention relates to is described.
Fig. 1 represents before being disposed in the seam 3 between concrete structure 2,2, from the sectional view of the flexible joint parts 1 during factory shipment.Flexible joint parts 1 can be formed by compliant members such as elastomeric materials sealing, comprise: be positioned at both sides and press on the block press section 4,4 of concrete structure 2,2, and the mode of the pressure born between the press section 4,4 of both sides and with Absorbable rod seam 3 folds the lamellar folding part 5 of arranging.
Folding part 5 has carries out processing to make to fold to become easy multiple folding portion 7.Folding part 5 has two folding portion 7a of center side and two folding portion 7b in outside.In the present embodiment, folding portion 7 is processed and be formed as wall thickness and be less than its adjacency section.Such as, be 8mm relative to the wall thickness of adjacency section, the wall thickness in folding portion 7 is 6mm.Each folding portion 7 processes in the length range throughout 10mm to 20mm.Be spaced apart about 30mm between adjacent folding portion 7a and folding portion 7b, between a folding portion 7a and another folding portion 7a, be spaced apart about 13mm.Flexible joint parts 1 from the length between 4 to press section, press section 4 be such as about 450mm.
Fig. 2 is the sectional view representing the seam 3 that is disposed between concrete structure 2,2 and be in the flexible joint parts 1 of folded state.Flexible joint parts 1 are formed as symmetrical relative to center line 9.Under the state of the folding arranging shown in Fig. 2, in cross sectional view, in the mode that the bottom 5c of flexible joint parts 1 is thinner than top, left side is formed as S font portion 5a, and right side is formed as anti-S font portion 5b.Top 5d is formed by general planar.Folding portion 7a is positioned at the bend on the top of S font portion 5a, and folding portion 7b is positioned at the bend of bottom.Similarly, folding portion 7a is positioned at the bend on the top of anti-S font portion 5b, and folding portion 7b is positioned at the bend of bottom.Flexible joint parts 1 are formed with S font portion 5a and anti-S font portion 5b in both sides, relative to bottom 5c and top 5d significantly necking down in an overlapping manner.
Flexible joint parts 1 shown in Fig. 2 are different from the parts that repeatedly ground turns back repeatedly in corrugated, but the reflex part crossing over seam 3 is simplified to one, in addition, because be formed with folding portion 7, so folding portion 7 can be utilized simply easily to bend, thus do not need to use die device, therefore, it is possible to efficiently easily bend.
Fig. 3 illustrates the seam 3 be disposed in by the flexible joint parts 1 shown in Fig. 2 between concrete structure 2,2, is then changed to the flexible joint parts 1 of swelling state from folded state due to the pressure born from seam 3.
Although the reflex part of the flexible joint parts 1 shown in Fig. 2 is reduced to one, but form S font portion 5a and anti-S font portion 5b in both sides, and relative to bottom 5c and top 5d significantly necking down in an overlapping manner, therefore, as shown in Figure 3, the flexible joint parts 1 being in swelling state can form the vast space of Absorbable rod pressure, and described space is formed by with the straight part of the circumferential part and both sides that are spaced apart the semicircle of diameter between the press section 4,4 of both sides.
Next, the second embodiment for flexible joint parts 1 of the present invention is described.
In the present embodiment, folding portion 7 is chemically treated and more easily folds for comparing its adjacency section.As chemical treatment, there is folding portion 7 is compared chemical treatment that adjacency section has larger caoutchouc elasticity.In addition, also low-density can be realized by making folding portion 7 become such as spongy.In addition, as chemical treatment, compare adjacency section to make folding portion 7 and be more easily out of shape, wet goods can be provided in folding portion 7.In addition, the different material in the portion of being adjacent also can be utilized to form folding portion 7, then this portion of being adjacent of folding portion 7 be synthesized one.
Next, with reference to Fig. 4 and Fig. 5, be described for the example that above-mentioned flexible joint parts 1 are applied to concrete structure expansion joint.
Concrete structure expansion joint 20 comprises: flexible joint parts 1, and the flexible material arranged by the seam 3 of crossing between concrete structure 2,2 is formed; And multiple fixed part 9, for concrete structure 2,2 is fixed in flexible joint parts 1 pressing.
Flexible joint parts 1 comprise in both sides and the press section 4 pressing on concrete structure 2 and the mode of pressure of bearing from seam 3 between the press section 4 of both sides and with Absorbable rod fold the folding part 5 of arranging, and folding part 5 has carries out processing making foldingly becoming easy folding portion 7.
Fixed part 9 comprises: the abutting part 6 of cross section コ font, is being covered in press section 4 on length direction; And multiple fixed cell 10, on the length direction at abutting part 6, in many places, concrete structure 2,2 is fixed in abutting part 6 pressing being covered in press section 4 at spaced intervals.
Fixed cell 10 has: pressure section 11, is covered in the abutting part 6 that section deformation is コ font; And anchor bolt and nut 14, be made up of bolt 12 and nut 13, for be coated with pressure section 11 at the abutting part 6 being covered in press section 4,4 state under, by pressure section 11 pressing be installed on concrete structure 2, press section 4 is pressed on concrete structure 2.Bolt 12 hammers into concrete structure 2, and nut 13 is anchored on bolt 12 via the pad 18 placed on pressure section 11 from the top side of bolt 12.
The abutting part 6 being covered in press section 4 is positioned at seam 3 side relative to bolt 12 in cross sectional view, and in the diagram, the abutting part 6 on right side is positioned at seam 3 side relative to the bolt 12 on right side, and the abutting part 6 in left side is positioned at seam 3 side relative to the bolt 12 in left side.
Outstanding projection 4a is formed at the soffit of press section 4.Be pressed against the face 2a of concrete structure 2 by press section 4, projection 4a is by compressive strain, and sealing becomes more reliable.
Be coated with protection rubber 19 in the upside of flexible joint parts 1, the end 19a of protection rubber 19 twists between press section 4 and abutting part 6.
Fig. 5 is the plan view representing concrete structure expansion joint 20.As shown in Figure 5, multiple fixed cell 10 is disposed on the length direction of abutting part 6 at spaced intervals, by anchor bolt and nut 14, concrete structure 2 is fixed in abutting part 6 pressing being covered in press section 4.
When bearing pressure from seam 3, protection rubber 19 extends, and the parts of flexible joint simultaneously 1 become the swelling state shown in Fig. 3, thus form the vast space of Absorbable rod pressure.
According to the present embodiment, flexible joint parts 1 have and carry out processing making foldingly becoming easy folding portion, therefore die device is not relied on by utilizing folding portion to carry out bending, thus can high-efficient simple ground assembling concrete works expansion joint 20.
