Description

Pillar assembly of protecting walls

The present invention is about supporting the pillar composite member of retaining wall, specifically about being easy to the pillar composite member of the retaining wall mounting and dismounting.

In the construction of various construction workss, for example house, road, in the construction such as water channel or dykes and dams, first by soil, sand or stone scrape out pit, then carry out various constructions inside.In this evacuation works, build up a retaining wall, prevent the avalanche of surrounding soil sandstone.

Therefore,, in order to form a retaining wall, some sheet piles, by relation adjacent to each other, are thrown in the desired depth in ground.Then, crossbeam is fixed to above sheet pile, conventionally between relative crossbeam, loads onto pillar.Crossbeam and retaining wall pillar are by being regulated by manual operation together with the jack of its length is connected to each other.The length of jack can make adjustments, and makes shore supports live this crossbeam or support between two retaining wall pillars, prevents that sheet pile from tilting to pit under ground pressure.

But because the handle of jack need to be rotated by manpower, the installation of jack and the labour intensity of adjusting are very large.Pillar being installed to behind suitable position with aforesaid way, under ground pressure, be easy to fall.In addition, because jack is squeezed from two sides under ground pressure, therefore want release handle very difficult, consequently must adopt and make pillar fall methods such as hammering.

Understand according to the inventor, in Japanese patent application TOHKEMY clear 55～16143, described a kind of and the immediate dado structure of the present invention, as shown in Figure 1.In the drawings, 1a, 1b is axle, 2a, 2b is connector, the 3rd, dull and stereotyped, the 4th, bolt hole, the 5th, bolt, the 6th, nut and 7 is pillars, the 8th, pivot, 8a is the device that prevents that pivot 8 from rotating and unclamping, the 9th, axle 1a, the 1b attachment point to pillar 7.Axle 1a, 1b in Fig. 1 and pillar 7 and the Fig. 2 that represents the embodiment of the present invention, 3a～3c, 4,5 or 6 B-C posts 14 are corresponding with sheet pile 11.Connector 2a, 2b is made up of two flat boards 3 respectively, they,, in the position tilting with the longitudinal axis of axle 1a, 1b, are fixed on axle 1a, 1b, respective end.On dull and stereotyped 3, the direction parallel with axle 1a, 1b longitudinal axis has bolt hole 4.Two dull and stereotyped 3 use bolts 5 connect and are fastened on, and bolt 5 is not acted on axle 1a, the impact of the ground pressure on 1b, and therefore dismounting is all very convenient.Remove after this connection, axle 1a curves herringbone around pivot 8 under ground pressure, and axle 1a and 1b can easily be pulled down.

Referring to Fig. 1 to 3, pillar composite member of the present invention is done general sign with the number of marking on a map 20.Pillar composite member 20 is connected by the mutual bunchiness of three

contiguous blocks

21,22 and 23.In the present embodiment, contiguous block 21 to 23 use bolt and nuts 24 are connected.In practice of construction, selected by the difference of hole 13 sizes, the pillar 14 of one or several predetermined lengths, select in this example i iron, and contiguous block 21 to 23 is selected from the prefabricated contiguous block of many various sizes, therefore when contiguous block is connected and puts timing, roughly extend through crossbeam 12 completely and be welded in the gap between an end plate 14a on pillar 14 ends.End plate 14a can be connected in advance with contiguous block 21 to 23 in factory, transports to job site, and contiguous block 23 is connected with crossbeam mouth.Also can, in advance in factory, the end plate 14a of contiguous block 21 use bolt and nuts 24 and pillar 14 be connected, contiguous block 23 is connected with crossbeam 12 at the construction field (site).Finally contiguous block 22 is inserted between

contiguous block

21 and 23 at the scene, connects with bolt and nut 24.The most handy bolt and nut 24 connects contiguous block, end plate and crossbeam.Can be with a screw wrenching tool not shown in the figures, at the scene bolt tightening.Screw wrenching tool is provided with an end pieces, is used for containing bolt, is rotated bolt tightening.As shown in Figure 2, pillar composite member 20 is fixedly connected with on the position between pillar 14 and crossbeam 12, thereby composite member 20 does not have the danger of accidental fall.

In Fig. 3 a to 3c, show the phantom drawing of contiguous block 21 to 23, thereby can see from the outside its inside.Contiguous block is hollow contiguous block, by upper plate 21a, and lower plate 21b, and have the not perpendicular side plate 21c of the fastening bolt through hole of label to form, and there is an inclined side plate 21d, there is the not through hole of label above, for inserting fastening bolt, and there is an interior reinforcement plate 21e.The structure of contiguous block 22 is identical with contiguous block 21, and difference is only the side plate 21c of the vertical stretching of contiguous block 21, and with inclined side plate 22c replacement, therefore contiguous block 22 has the side plate 22c of two inclinations, 22d.Therefore, used the identical number of marking on a map to represent, and omitted the narration about contiguous block 22 other assemblies.Contiguous block 23 and contiguous block 21 also have identical structure, and difference is that contiguous block is symmetrical mutually, thereby the mark number identical with contiguous block 21 of contiguous block 23 use represent, the narration of repetition is corresponding omission also.

Can find out from Fig. 2 to 4, when

contiguous block

21,22 and 23 bunchiness are connected, form the entirety of a positive parallelepiped, as the extension of pillar 14.As shown in Figure 4, longitudinally axis X of the pressure of retaining wall 10, effect on pillar composite member 20 and pillar 14, to prevent that sheet pile 11 from tilting to hole 13.The oblique side plate 21d of contiguous block 21, recline with the oblique side plate 22c of contiguous block 22, the vertical plane of the longitudinal axis of inclined plane and pillar 14 and pillar composite member 20 tilts, and the prism 22d of contiguous block 22 and the prism 23c of contiguous block 23 recline, and tiltedly the vertical plane Z of abutment face and X-axis tilts.Hereinafter will explain orally: key of the present invention is the adjacent piece that is posted by connecting, the vertical plane of its abutment surface and pillar and pillar composite member longitudinal axis tilts.

After the predetermined operation of hole in 13, retaining wall 10 must be dismantled, fixing on pillar 14 by steel cable (not shown), for not shown in the figures when hanging handle post 14 and mentioning, pillar 14 in the time dismantling not reason gravity fall.Then resolution stand composite member 20.At this moment, as shown in Figure 1,
