Description
Technical Field
The utility model relates to a post-cast strip bearing structure, in particular to easy removable inner support structure of post-cast strip.
Background
In order to prevent harmful cracks possibly generated by uneven temperature and shrinkage of a cast-in-place reinforced concrete structure in the construction process, temporary construction joints are reserved at corresponding positions of a foundation slab, a wall and a beam during construction in the former period according to design or construction specification requirements, the structure is temporarily divided into a plurality of parts by the temporary construction joints, the parts are shrunk through the inside of the components, concrete is poured and tamped at each temporary construction joint during construction in the later period, and the structures are connected into a whole. The post-cast strip is concrete poured and pounded at the temporary construction joint. High-rise and super high-rise buildings are more and more in modern building construction, and foundation parts of the buildings are deeper and deeper. The post-cast strip of foundation slab and wall body adopts traditional post-cast strip to reserve the mode of establishing mostly, and the post-cast strip must pour the post-cast strip concrete after the major structure construction is accomplished, therefore must continuously carry out precipitation in order to guarantee that the groundwater level is below the foundation slab. Long-term precipitation not only increases construction cost, but also wastes underground water resources. In addition, for deep underground foundation engineering, if earth is not quickly backfilled after the foundation is finished, potential hazards are brought to the safety of the foundation engineering, and the construction of other procedures can be influenced without backfilling the foundation earth, so that the construction period of the engineering is influenced.
In recent years, the problems are solved by adopting an advanced water-stop post-cast strip construction technology, wherein the advanced water-stop strip is formed by adding a telescopic concrete bottom plate or a guide wall at a temporary construction joint during early construction, and arranging a rubber water-stop strip at the expansion joint. Such a water stop used at the post-cast position and cast prior to the post-cast is called a leading water stop. The advanced water stop belts are all related to the retention of an expansion joint in the middle of the advanced water stop belt, an extruded polystyrene board or a wood fiber asphalt board is filled in the expansion joint, and a rubber water stop belt is arranged in the middle of the expansion joint. However, the structure has certain defects, and the rubber waterstop is easy to deviate and crack in the concrete pouring construction due to poor fixation; the extruded polystyrene board or the wood fiber asphalt board has insufficient strength to cause deformation in construction. The defects can cause the leading water stop to leak water, bring adverse effects to the water prevention of the post-pouring strip and seriously bring adverse effects to the building safety.

The easy-to-dismount internal support structure for the post-pouring belt comprises a steel plate water stop belt, pin holes, a support structure plate, support rods, shaft sleeves, pin shaft supports, a steel plate, butterfly bolts and wood plates; the steel plate water stop is arranged between two supporting structure plates, the supporting structure plates are main body structure plates and are positioned at two sides of the post-cast strip, and the supporting structure plates comprise wood plates; the pin shaft support penetrates through a pin hole in the supporting structure plate and is fixed on a steel plate of the wood plate through a butterfly bolt; the pin shaft support is connected with the supporting rod, and the supporting structure plates which are opposite in position are connected with each other through the supporting rod and the shaft sleeve.
Preferably, the method comprises the following steps: the end part of the pin shaft support is connected with one end of a support rod, and the other end of the support rod is connected with a shaft sleeve in a sleeve mode; the support rod is of an L-shaped structure.
Preferably, the method comprises the following steps: two fixing plates are arranged between the two shaft sleeves and are connected in a reinforcing mode through spiral nuts and spiral bolts.
Preferably, the method comprises the following steps: the bottom support is installed to the plank lower extreme, and the plank outside sets up the steel sheet, and the reinforcing bar tooth is installed at the plank top, and the lower part all installs the frame that protects on the plank.
The utility model has the advantages that:
1. the utility model discloses be provided with devices such as axle sleeve, fixed plate between two relative bearing structure boards in position of easy removable inner support structure of post-cast strip, dismantle easily, solved in the past have the problem that post-cast strip bearing structure of steel sheet waterstop can not dismantle, the installation is demolishd portably.
2. The utility model discloses a round pin axle support and pinhole can use repeatedly, and material saving also guarantees post-cast strip geometric dimensions easily.
