Description

Technical Field

[0001] The utility model relates to the technical field of cable trench building templates, in particular to a template structure used for cable trench deformation joints. Background Art

[0002] Cable trenches often deform due to external factors such as thermal expansion and contraction of the ground, leading to cracks or even damage. To avoid cracks and damage caused by such expansion and contraction, we need to reasonably set expansion joints in the cable trenches. Cable trench projects have the characteristics of long buildings and many expansion joints. Due to the restrictions on the width of the expansion joints, the efficiency and quality of demolding at the position of the expansion joints are technical difficulties in the continuous pouring of the cable trench.

[0003] At present, the existing technology is to place a deformation joint isolation plate in the deformation joint and then cast the concrete. After the concrete solidifies, the isolation plate is removed. Due to the narrow deformation joint space, the isolation plate is difficult to remove and the demoulding takes a long time. Therefore, it is necessary to provide a template structure for the deformation joint of the cable trench to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a template structure for a cable trench deformation joint, which can be easily taken out from the deformation joint during dismantling, thus reducing the time consumption of demoulding.

[0007] Furthermore, the lower auxiliary side template, the main side template and the upper auxiliary side template are all in contact with the pulleys.

[0008] Furthermore, the front surfaces of the upper secondary middle template, the main middle template and the lower secondary middle template are all provided with a first hollow handle hole, and the front surfaces of the lower secondary side template, the main side template and the upper secondary side template are all provided with a second hollow handle hole.

[0009] Furthermore, the template structure also includes a first slot and a third slot; the upper sub-middle template and the two upper sub-side templates are all inserted into the first slot, and the lower sub-middle template and the two lower sub-side templates are all inserted into the third slot.

[0010] Furthermore, the template structure also includes a second slot, which is connected to the first slot and the third slot to form a U-shape, and the main middle template, the upper sub-middle template, the lower sub-middle template, the main side template, the upper sub-side template and the lower sub-side template are all inserted into the second slot.

[0012] Compared with the related art, the utility model has the following beneficial effects:
