Description
Technical Field
The invention mainly relates to the field of post-cast strip supports, in particular to a telescopic post-cast strip support.
Background
With the rapid development of the modern building industry, ultrahigh, ultra-long and large underground garage buildings are increasingly increased, and higher requirements are put forward on the anti-settlement and temperature stress capabilities of the underground buildings. The prior art generally eliminates the effects of temperature and settling stress by providing post-cast belts. However, the time interval from the reserving to the pouring of the post-cast strip is longer, and the requirement on the whole supporting system is higher. The traditional post-cast strip supporting system and the post-cast strip independent supporting system emerging in recent years have the following problems;
the traditional post-cast strip supporting system is difficult to be separately erected with a peripheral template and a back edge in actual construction. When the post-cast strip is not closed and the components on the two sides are in a cantilever state, once the supporting system is dismantled and jacked back, the components sink to form destructive cracks, even quality accidents, and the significance of independently erecting a formwork supporting system is lost.
Traditional post-cast strip supports support body is full of hall to erect, has all caused very big hindrance to rubbish clearance, construction material transportation. A large amount of materials such as the templates, the back edges, the frame bodies and the like are overstocked in the supporting system, a large amount of the cargos are overstocked for a long time, and the rental cost of the cargos is increased.
The independent post-cast strip supporting system emerging in recent years seems to solve the problem of traditional post-cast strip supporting, and when the independent post-cast strip supporting system is matched with a traditional wood formwork in use, a jacking support is not matched with the wood formwork and a back-to-back stupefied steel pipe in a crossed frame mode, so that the effect of retaining independent supporting and dismantling other formwork supporting systems cannot be achieved. And when the post-cast strip reaches the casting closed condition, the frame body and the template need to be erected for the second time. The problems cause that the operability of the emerging post-cast strip independent supporting system is not strong in practical project application, and waste is easily caused on construction resources and cost.

Selecting the number of the middle vertical rods according to the supporting height, and roughly adjusting the overall supporting height of the post-cast strip;
the length of the upper vertical rod is adjusted by adjusting the limiting part, and the overall height of the post-cast strip support is finely adjusted;
the integral height of the post-cast strip is finely adjusted by rotating the screwing relationship among the upper upright rod, the middle upright rod, the lower upright rod and the sleeve, and finally the top support and the peripheral template are fixed by using a bolt after the top support and the peripheral template are positioned on the same horizontal plane;
and after the concrete pouring is finished and the form removal age is reached, removing the support and the surrounding support frame body.
The invention has the following beneficial effects:
by adopting the telescopic post-cast strip supporting system of the technical scheme, the jacking supports can replace templates to be used, and the jacking supports can form a system with all common templates, so that the phenomenon that the jacking supports are crossed with peripheral templates, back edges and steel pipes to form a frame is avoided. The peripheral templates can be smoothly removed without removing the immovable steel columns after the requirement of removing the templates is met. When the post-cast strip reaches the casting closed condition, a plurality of groups of the supporting systems can be erected to be matched with the supports on the two sides of the post-cast strip to replace the traditional method of erecting a frame body and a template for the second time.
The invention can be manufactured in advance according to the requirements of a construction site, and has the advantages of simple and convenient manufacture and flexible and convenient use. The post-cast strip independently supports the installation work load less, only supports in the beam slab of post-cast strip both sides, and installation easy operation is convenient, and the commonality is strong, can have enough to meet the need the use, can reduce the use amount of turnover materials such as steel pipe template in a large number simultaneously, reduce cost.
