Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses a connection structure of precast beam and precast slab, including precast beam 1 and precast slab 2, integrated into one piece has a plurality of sand grips 3 on precast slab 2 and precast beam 1's the relative lateral wall, and sand grip 3 sets up along precast slab 2's direction of height, forms recess 4 between two liang of sand grips 3, has all placed pre-buried section bar 5 in every recess 4, and pre-buried section bar 5's lateral wall and sand grip 3's lateral wall looks butt, and one side of pre-buried section bar 5 is connected with waterstop 6, and it has the concrete to fill between precast beam 1 and precast slab 2.
Wherein, a screw 7 is fixed on one side of the pre-buried section bar 5, and a threaded hole 8 in threaded connection with the screw 7 is arranged on one side of the water stop bar 6. After pouring the concrete between precast beam 1 and precast slab 2, treat that the concrete is placed a period of time after, will stimulate pre-buried section bar 5 for waterstop 6 is located the concrete, then rotate pre-buried section bar 5, make pre-buried section bar 5 and waterstop 6 separation, simple structure, convenient operation, the staff of being convenient for retrieves and recycles pre-buried section bar 5.
In order to facilitate the water stop bar 6 to enter the empty groove left when the prefabricated section bar leaves the concrete, a guide fillet is arranged on one side of the water stop bar 6 facing the concrete, and the water stop bar 6 provides a guiding effect through the guide fillet, so that the water stop bar 6 is convenient to enter the empty groove left when the prefabricated section bar leaves the concrete.
Then, in order to avoid that the water stop strip 6 is expanded when meeting water and leads to the water stop strip 6 can't get into the empty groove that the precast profile left when leaving the concrete when pouring the concrete, the lateral wall cover at the water stop strip 6 is equipped with the layer and keeps apart the protection film. Avoid sealing rod 6 and water contact through keeping apart the protection film to avoid sealing rod 6 inflation grow, when packing into the prefabricated section bar with sealing rod 6 and leaving the dead slot that the concrete was left, will keep apart the protection film and tear, make sealing rod 6 play water-proof effects.
In order to stably install the water stop strip 6 in the groove 4, the cross section of the convex strip 3 is in an equilateral trapezoid shape, and the longer side of the convex strip is close to the precast beam 1. When water stop 6 meets water inflation, the transversal equilateral trapezoid of personally submitting of sand grip 3 can make in the empty groove that joint that water stop 6 can be more firm left when precast profile leaves the concrete for water stop 6's installation is more stable.
Then, water stop steel plates 9 are attached to the opposite side walls of the beads 3. Through stagnant water steel sheet 9, after the concrete accomplished the watering, stagnant water steel sheet 9 gomphosis plays the infiltration that blocks water in the concrete, improves precast beam 1 and precast slab 2 connection structure's water-proof effects.
It is worth mentioning that, in order to facilitate the staff to pull out prefabricated section bar from the concrete, be provided with the portion of holding 10 in the one side of pre-buried section bar 5 keeping away from sealing rod 6, provide the stress point for the staff pulling prefabricated section bar through the portion of holding 10 to the staff of being convenient for pulls out prefabricated section bar from the concrete.
Then, in order to avoid that the worker pulls the embedded section 5 to an excessive extent to draw out the water stop bar 6, a blocking piece 11 is arranged on one side of the water stop bar 6 far away from the prefabricated section, and the cross section of the blocking piece 11 is larger than that of the water stop bar 6.
The implementation principle of the embodiment is as follows: install prefabricated plate 2 and precast beam 1 in appointed position, put into corresponding recess 4 with pre-buried section bar 5, then to pouring concrete between prefabricated plate 2 and the precast beam 1, treat the concrete setting back, take out the prefabricated section bar, make in sealing rod 6 gets into recess 4, when water seeps in through the gap between prefabricated plate 2 and the precast beam 1, can prolong the flow path of water through sand grip 3, slow down the time of water infiltration, when water infiltration and sealing rod 6 contact, sealing rod 6 meets the water collision, and the extrusion is in the concrete, block the way of rivers, play waterproof effect.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
