Description

Technical Field

[0001] The invention relates to the technical field of caisson casting construction, and in particular to a caisson inner mold component, a template system, and a caisson casting method. Background Art

[0002] The casting of caisson generally includes the casting of the bottom and side walls. The casting of the side walls requires the formwork on both sides of the side walls to form a casting space for the side walls, and then the casting is carried out. For tall caissons (height ≥ 15m), due to their high height, during the experiment, it was found that if industrialization is to be realized (application in engineering), the side walls must be cast through at least two times of setting up the formwork on the inside and outside. Therefore, the inner formwork of the side wall needs to be designed to be horizontally telescopic, that is, the horizontal width of the formwork can be changed. In this case, at least 3 telescopic devices (such as cylinders) are required to be synchronously extended to achieve the change of the horizontal width of the formwork, but the synchronous extension and retraction control of multiple telescopic devices is difficult, resulting in a higher cost for the inner formwork. Summary of the invention

[0003] The purpose of the present invention is to overcome the problem that it is difficult to control the synchronous extension and retraction of multiple extension devices in the background technology, which leads to high cost of the inner formwork, and to provide a caisson inner formwork assembly, a formwork system, and a caisson casting method.

In the above process, only two of the active telescopic mechanisms are needed to synchronously extend and retract to drive the inner mold side template to move laterally and reach a predetermined position, and the remaining first telescopic devices are subsequently extended and support the inner mold side template, and there is no need for all the first telescopic devices to extend and retract synchronously, thereby effectively reducing the control difficulty of the extension and retraction of the first telescopic devices, thereby reducing the cost of the caisson inner mold assembly.

The second connecting hole is a through hole. The connecting bolt 14 passes through the second connecting hole and is threadedly connected to the first connecting hole. The nut of the connecting bolt 14 abuts the surface of the connecting screw 12.

[0097] The first connecting hole is arranged at the head of the fish bolt 11, and the second connecting hole is arranged on the connecting screw 12. The first connecting hole has an opening facing the inner concave hole, and the opening is connected to one opening of the second connecting hole, and the other opening of the second connecting hole faces outward; the first connecting hole is arranged along the axial direction of the fish bolt 11, and the second connecting hole is colinear with the axial direction of the first connecting hole. The connecting bolt 14 can extend into the second connecting hole from the opening of the second connecting hole toward the outside, and extend into the first connecting hole from the opening of the first connecting hole opposite to the other opening of the second connecting hole.

[0098] By having the connecting bolt 14 penetrate through the connecting screw 12 and extend into the connecting fish bolt 11, the connection strength between the fish bolt 11 and the connecting screw 12 can be increased on the basis of the connecting nut 13; on the other hand, the threaded connection section between the connecting nut 13 and the fish bolt 11 and the connecting screw 12 can be reduced while meeting the strength requirements, the length of the connecting nut 13 can be shortened, the depth of the inner recessed hole can be reduced, the damage to the integrity and strength of the caisson side wall caused by the inner recessed hole can be reduced, and it is also more convenient to remove the connecting nut 13.

[0099] Preferably, the nut of the connecting bolt 14 abuts against the surface of the connecting screw rod 12 , and the connecting bolt 14 is threadedly connected to the first connecting hole. The connecting bolt 14 can connect the connecting screw rod 12 and the fish bolt 11 through the abutment and threaded connection of the nut.

[0100] The connecting nut 13 connects the fish bolt 11 and the connecting screw 12. The connecting screw 12 protrudes from the side wall of the caisson, which is convenient for connecting with the outer mold upper template 215 or the operating platform 110. The tail of the fish bolt 11 is anchored in the side wall of the caisson, which can provide a large anchoring force for the fixation of the outer mold upper template 215 or the operating platform 110; the connecting nut 13 is threadedly connected with the fish bolt 11 and the connecting screw 12. After use, the connecting nut 13 and the connecting screw 12 can be removed by screwing with less damage to the side wall of the caisson; a first connecting hole is set in the fish bolt 11, and a second connecting hole is set in the connecting screw 12. The first connecting hole is penetrated by the connecting bolt 14 The hole and the second connecting hole increase the connection strength between the connecting screw 12 and the fish bolt 11 on the basis of the connection of the connecting nut 13, and can reduce the length of the connecting nut 13 while meeting the connection strength requirements, thereby reducing the damage to the integrity and strength of the caisson side wall and making it easier to remove the connecting nut 13; since the fish bolt 11 is completely located in the inner recessed hole, the inner recessed hole can be sealed by grouting, and the fish bolt 11 can be conveniently and inexpensively buried in the caisson side wall, thereby cutting off the connection between the fish bolt 11 and the outside world, reducing the probability of formation of rust channels connecting the inside and outside of the caisson side wall, and thereby slowing down the corrosion rate of the steel inside the caisson side wall and extending the service life of the caisson.

[0105] The outer mold lower template 214 and the bottom mold structure 213 are fixed to each other, specifically:

[0106] The outer mold lower mold plate 214 is limitedly matched with the bottom mold structure 213 in the horizontal direction;

[0107] Install a push structure 215 on the outer side of the outer mold lower template 214;

[0108] The push structure 215 pushes the lower part of the bottom mold structure 213 so that the push structure 215 and the bottom mold structure 213 clamp the lower part of the outer mold lower mold plate 214 .

[0109] The lower part of the side wall of the caisson 200 is cast between the outer mold lower template 214 and the inner mold lower template 217, and the first connecting member 219 and the second connecting member 221 are embedded in the upper part of the cast outer wall of the side wall, and a groove 220 is preset in the upper part of the cast inner wall of the side wall.

[0110] The outer mold lower template 214 and the inner mold lower template 217 are removed.

[0111] The operating platform 110 is connected to the first connecting member 219, and the operator connects the lower part of the outer mold upper template 215 to the second connecting member 221 on the operating platform 100, and the lower part of the outer mold upper template 215 is detachably connected to the operating platform 100;

[0112] The lower part of the caisson inner mold assembly 211 is hoisted into the inner side of the poured side wall, and the extending legs 204 are extended into the corresponding grooves 220. At this time, the first telescopic devices are in a retracted state.

[0113] The active telescopic mechanism 280 extends, driving the inner mold side template 202 to move laterally and reach a predetermined position.

[0114] The first passive telescopic mechanism 281 is increased to a predetermined length and fixed by a fixing device 205 , so that the first passive telescopic mechanism 281 laterally supports the inner mold side template 202 , and the length of the first passive telescopic mechanism 281 is fixed by the fixing device 205 .

[0115] The upper part of the outer mold upper template 215 is pulled against the upper part of the caisson inner mold assembly 211.

[0116] The corresponding part of the side wall of the caisson 200 is cast between the outer mold upper template 215 and the caisson inner mold assembly 211. Specifically preferably, in S6, the first connecting member 219 and the second connecting member 221 are pre-embedded on the upper outer side of the corresponding part of the side wall of the cast caisson 200, and a groove 220 is preset on the upper inner side. Then, the operating platform 110, the outer mold upper template 215 and the caisson inner mold assembly 211 are lifted, and the operating platform 110 is connected to the upper first connecting member 219. The operator connects the lower part of the outer mold upper template 215 on the operating platform 100 with the upper second connecting member 221, and the extended leg 204 is extended into the upper groove 220. At this time, the lower part of the outer mold upper template 215 is detachably connected to the operating platform 100, and the first telescopic devices are in a retracted state. Then, S3-S6 are repeated until the casting of the side wall of the caisson 200 is completed.

[0117] The buttress 218 is preferably a concrete member.

[0118] After the side wall of the caisson 200 is poured, the outer mold upper template 215 and the caisson inner mold assembly 211 are removed, and the operating platform 110 is still connected to the side wall of the caisson 200.

[0119] The operating platform 110 is used as an operating platform for installing the breast wall side wall outer formwork assembly 130 , and the breast wall side wall outer formwork assembly 130 is used to cast the breast wall 170 on the upper part of the caisson 100 .

[0120] The present invention discloses a caisson casting method. During construction, the lower part of the side wall of the caisson 200 is cast first, and a groove 220 is preset on the upper part of the inner wall of the cast side wall. Then, the lower part of the caisson inner mold assembly 211 is hoisted into the inner side of the cast side wall, and the extended legs 204 are extended into the corresponding grooves 220. At this time, the first telescopic devices are in a retracted state. Then, the active telescopic mechanism 280 is extended. Since a track 206 that slidably cooperates with the inner mold side mold plate 202 is provided on the main frame 201 along the telescopic direction of the active telescopic mechanism 280, and the track 206 supports the weight of the inner mold side mold plate 202, the active telescopic mechanism 280 can easily drive the inner mold side mold plate 202. The plate 202 moves laterally and reaches a predetermined position; then the first passive telescopic mechanism 281 is increased to a predetermined length and fixed by a fixing device 205, so that the first passive telescopic mechanism 281 laterally supports the inner mold side template 202, and the length of the first passive telescopic mechanism 281 is fixed by the fixing device 205. In the above process, only two of the active telescopic mechanisms 280 need to be synchronously telescoped to drive the inner mold side template 202 to move laterally and reach a predetermined position, and the remaining first telescopic devices can be subsequently extended and supported by the inner mold side template 202. It is not necessary for all the first telescopic devices to be synchronously extended and extended, thereby effectively reducing the control difficulty of the extension and retraction of the first telescopic devices, thereby reducing the cost of the caisson inner mold assembly.

[0121] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
