In figure, be labeled as: vertical rod 1, horizon bar 2, fastener 3, top board 4, plane top board 41, cascaded surface type top board 42, tapered plane type top board 43, body of wall 5, cylinder 6, top board cutting seam 7, interplanar spacing D1, cascaded surface space D 2, tapered plane space D 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
Large-sized concrete structural demolition method as shown in Figure 1, Figure 2, Figure 3 shows, comprises top board 4, and is arranged at cylinder 6 and the body of wall 5 of top board 4 belows for roof supporting 4, comprises the following steps:
A, choose at least one vertical rod 1, at least one horizon bar 2 and at least one for by the fastener 3 fastening intersection area of vertical rod 1 and horizon bar 2 according to the bulk of large-sized concrete structure to be removed;
B, by the bottom surface close contact of the top of described vertical rod 1 and top board 4, described horizon bar 2 is close to termination and cylinder 6 or body of wall 5 close contacts of cylinder 6 and body of wall 5, and by fastener 3 by fixing crossing vertical rod 1 and horizon bar 2;
C, by cutting equipment, top board 4 is cut, described top board cutting seam 7 separates with cylinder 6 top board 4 with body of wall 5, and by hanging device, top board 4 is hung;
D, by cutting equipment, cylinder 6 and body of wall 5 are cut, and by hanging device, cylinder 6 and body of wall 5 are hung;
E, dismounting vertical rod 1 and horizon bar 2.
In actual operation, many vertical rods 1 and the described support system of the orthogonal crossing formation of many horizon bars 2 often.General, need to adopt the concrete structure of method for dismounting of the present invention all to belong to comparatively large-scale concrete structure.In the time of concrete placement vertical rod 1 and horizon bar 2, first by the bottom surface close contact of the top of vertical rod 1 and top board 4, thereby ensure that the bottom surface that vertical rod 1 is top board 4 provides support; Then horizon bar 2 is close to termination and cylinder 6 or body of wall 5 close contacts of cylinder 6 and body of wall 5, thereby ensures to provide support for cylinder 6 or body of wall 5; For the intersection area of vertical rod 1 and horizon bar 2, fastening by fastener 3.Completing after above-mentioned Bracing Systems structure, can remove operation.Concrete dismounting operation is first by cutting equipment, top board 4 to be cut, and described top board cutting seam 7 separates with cylinder 6 top board 4 with body of wall 5, and by hanging device, top board 4 is hung.As shown in Figure 1, general, cutting seam 7 tracks are that vertical direction cuts along top board 4 thickness directions, ensure that hanging device can hang top board 4 easily.Next, by cutting equipment, cylinder 6 and body of wall 5 are cut, and by hanging device, cylinder 6 and body of wall 5 are hung.So far, completed the complete removal work to large-sized concrete structure.Last, remove vertical rod 1 and horizon bar 2 by dismounting fastener 3.The present invention allows the dismounting operation of large-sized concrete structure greatly simplify, and has also broken away to a great extent the dependence to the outer carrier strip part of equipment, construction environment etc. in conventional solution, has not only improved dismounting efficiency, has also reduced dismounting cost.
Generally speaking, as shown in Figure 1, the top board 4 of large-sized concrete structure can be divided into plane top board 41, cascaded surface type top board 42, tapered plane type top board 43 three types substantially.In conjunction with concrete dismounting experience, steel cable is well socketed on top board 4 in the time that top board 4 is left under order for convenient, taking plane top board 41 as example, can be chosen in the interplanar spacing D1 between horizon bar 2 and the bottom surface of plane top board 41 topmost in horizon bar 2 and be at least 20cm.Such space provides very sufficient operating space for operating personnel arrange steel cable.Based on same thought, for cascaded surface type top board 42, can selection level bar 2 in horizon bar 2 topmost and cascaded surface type top board 42 the cascaded surface space D 2 between the bottom surface in the top be at least 20cm.For tapered plane type top board 43, can selection level bar 2 in tapered plane space D 3 between horizon bar 2 and the bottom surface top of tapered plane type top board 43 be topmost at least 20cm.
The present invention, through the application of practice, not only allows the dismounting operation of large-sized concrete structure greatly simplify, and in addition, owing to having saved the operations such as the pre-lifting measure of driving, also allows dismounting cost greatly reduce.The present invention is particularly useful for removing large-sized concrete structure.
