Description
Technical Field
The invention relates to the technical field of building application equipment, in particular to a broken bridge split connecting rod piece of a reinforced form integrated wall form.
Background
At present, in the production process of precast concrete members, a formwork is generally dismantled after pouring is completed, so that the labor cost is increased, and material waste is caused. Along with the technical progress, the disassembly-free integrated pouring template can be used for replacing the traditional template, after the template is built and formed, the template is fixed by the connecting rod piece, pouring and maintenance are carried out until the requirement is met, and at the moment, the template, the wall body and the connecting rod piece pre-embedded in concrete form a whole without disassembly. The technical scheme reduces the construction process, reduces the cost, avoids material waste and meets the national requirements of energy conservation and emission reduction. On the other hand, the disassembly-free integrated pouring template has great limitation in use: the fixed templates are generally connected by adopting connecting rods, the connecting method has high strength and strong integrity, but the conventional connecting rods are generally made of metal materials, the heat transfer coefficient of the conventional connecting rods is obviously higher than that of other parts, and the problem of serious thermal bridge effect is caused.
Therefore, chinese patent application publication No. CN110219457A discloses a broken bridge split-draw connecting rod for a wall form integrated with a steel bar form, which comprises a broken bridge connecting piece, a long metal screw rod, a second metal screw rod, a gasket, engineering plastics, a structural adhesive, a long metal screw rod, a second metal screw rod, a long metal screw rod nut, a second metal screw rod nut, an air layer, a hollow slurry guiding and measuring cavity, a flexible sampling probe, a sampling groove and a non-encapsulated RFID anti-metal chip. During the use, handle through carrying out the bridge cut-off to traditional metal connecting rod spare, reduce metal rod spare's heat transfer efficiency, increase hot working property to avoid "hot bridge" phenomenon: the main structure of the screw-in type connecting rod piece and the middle bridge-cut-off connecting piece is made of engineering plastics, and the two sides of the screw-in type connecting rod piece are provided with metal screw rods. On the basis of ensuring the use function of the connecting rod piece, the middle section of the connecting rod piece is made of engineering plastics, so that the thermal bridge effect is greatly reduced.
However, the above invention has a disadvantage that under different working conditions, the distances between the two adjacent side walls are different, and for the two side walls in different places, the distance between the two side walls needs to be measured temporarily to customize the broken bridge opposite-pulling connecting rod piece with the corresponding length, which increases the investment cost in the previous period, increases the construction period, and makes the applicability of the broken bridge opposite-pulling connecting rod piece low.
