Description
Technical Field
The invention belongs to the technical field of construction machinery, and particularly relates to an adjustable template system for small-size deformation joint construction, which is convenient to disassemble and assemble, flexible to adjust, high in supporting strength and capable of being repeatedly used.
Background
In industrial and civil buildings, additional stress and deformation are generated inside the building structure due to the influence of factors such as temperature change, uneven settlement of a foundation, earthquake and the like, particularly the additional stress and deformation are amplified by small high-rise buildings and high-rise buildings, and the building structure cracks and even collapses if the additional stress and deformation is not properly treated. Therefore, the structure needs to be broken at sensitive positions where deformation is possible to generate in advance to form deformation joints, so that the building structures of all parts have enough deformation width in the deformation joints without damage, for example, deformation joints are arranged between shear wall structures in small and high-rise buildings. However, it can be known from the effect of the deformation joint that the deformation joint is generally narrow, and when the height of a frame-shear wall structure house does not exceed 15m and the width is not less than 100mm when a quakeproof joint is arranged as specified in the technical code of high-rise building concrete structures (JGJ 3-2010). Therefore, the width of the deformation joint of a building with small height is generally only 100-200 mm, the width of the deformation joint of a high-rise building and a small-rise building is generally only 200-500 mm, and the clearance distance of the deformation joint is small, so that the installation and the removal of the templates on two sides of the deformation joint are difficult, and particularly the small-size deformation joint of 100-200 mm is more difficult.
For the template construction of small-size deformation joints, the following three processes are often adopted in the prior art: the first is to adopt the polyphenyl board as the disposable template, but because the polyphenyl board intensity is lower, the expansion die and the explosion die are easy to appear on the inner side of the expansion joint after the concrete pouring and tamping are finished, the structural dimension and the verticality of the concrete section can not be ensured, and the rework and rectification cost is higher. The second is that the box that adopts wood veneer plus flitch to make and big such as movement joint is as the template, perhaps supports as the template with slabby strip piece preparation grid, nevertheless owing to receive the extrusion of both sides construction load, demolish comparatively difficultly after the later stage destroys, and does not tear open then because the rigid structure can direct influence the structure function of movement joint. And thirdly, a staggered-layer construction method is adopted on two sides of the deformation joint, but the deformation joint cannot be poured simultaneously, the construction period is longer, and the difficulty of safety protection and dynamic management of an upper operation layer and a lower operation layer is increased. Therefore, in the prior art, a deformation joint template is provided with a hole, a wall penetrating screw penetrating through a pre-embedded sleeve in a wall body is arranged in a penetrating mode, and the template on the outer side is fixed by pulling from the inner side of a wall column, so that the defects that wall columns on two sides of a small-size deformation joint cannot be poured simultaneously, or a polystyrene board needs to be filled between deformation joints, a wood box needs to be arranged, and the like are overcome. However, it should be seen that the above method requires pre-embedding of the sleeve in the wall column structure, which not only reduces the structural strength of the wall column and reduces the waterproof performance, but also tightens the wall-penetrating screws one by one, and the difference in the tension or the screwing amount of each screw reduces the flatness of the formwork, so that the structural dimension and the verticality of the concrete section cannot be accurately ensured, and the deformation joint needs to be re-manufactured after the dimension adjustment. In addition, the high-pressure air bags are used for inflating to support the formworks on two sides, and the formworks are convenient to move out through deflation and pressure reduction during dismantling, so that the adverse effect of construction residual garbage in deformation joints is solved although the formworks can be repeatedly used, but the problems that the formwork expansion and the formwork explosion are easy to occur after concrete pouring and tamping are difficult to avoid due to the fact that the supporting strength of the air bags after inflation is still limited. In addition, an oval steel pipe is adopted as a component, the support rod piece in the rotary top form removal device at the tail end of the oval steel pipe is opened and closed to adjust the space between the formworks, the purposes of efficient assembly and disassembly and recycling are achieved, however, the single support rod piece is easy to be unstable under strong construction load, the stress is too large and potential safety hazards exist only when the size is stabilized through the threaded connection of the upper small section, corresponding oval steel pipes are required to be manufactured for deformation joints with different sizes, the universal type is lacked, material waste is caused, and the use cost is high.
