Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and 2: the embodiment discloses a precast concrete spare connected node, including stand 1, crossbeam 3, be equipped with a plurality of stands in the stand 1 and indulge muscle 11, crossbeam 3 from the top down is equipped with in proper order indulges muscle 31, indulges muscle 32 down, and 1 lateral part of stand is equipped with side depressed part 13, and side depressed part 13 from the top down is equipped with connecting rod 2, bottom plate 4 in proper order, goes up connecting rod 2, 4 level settings of bottom plate and end connection in the stand and indulges muscle 11.
The other end of bottom plate 4 still is equipped with the ascending opening cutting ferrule 41 of a plurality of openings, and 3 stand link ends of crossbeam are equipped with grout hole 34, and the both ends of grout hole 34 all are equipped with end depressed part 35, and the lower extreme of bottom plate 4 still is equipped with detachable backplate 5, and backplate 5 still is equipped with row's grout hole 501.
When the end of the cross beam 3 is connected to the side concave part 13, the upper connecting rod 2 is connected to the upper longitudinal rib 31, the opening clamping sleeve 41 is connected to the lower longitudinal rib 32, the guard plate 5 is connected to the lower surface of the cross beam 3, mortar 7 is filled in the end concave part 35, the grouting hole 34 and the side concave part 13, and the mortar discharge hole 501 is communicated with the end concave part 35, that is, when the end of the cross beam 3 is connected to the side concave part 13, the cross beam 3 or the lower support plate 4 cannot block the mortar discharge hole 501.
In order to prevent the lower longitudinal rib 32 from disengaging from the open cutting sleeve 41, the end of the lower longitudinal rib 32 is provided with an upset section 321, and the diameter of the upset section 321 is larger than the inner diameter of the open cutting sleeve 41.
The inner surface of the opening cutting sleeve 41 is also provided with annular lines 411 (such as a plurality of annular grooves), the plane where the annular lines 411 are located is perpendicular to the axis of the lower longitudinal rib 32, and the annular lines 411 are used for increasing the attaching force between the inner surface of the opening cutting sleeve 41 and mortar.
In order to strengthen the intensity between the vertical column longitudinal rib 11 and the upper connecting rod 2 and the lower supporting plate 4, and simultaneously avoid the deformation of the connecting nodes of the upper connecting rod 2, the lower supporting plate 4 and the vertical column longitudinal rib 11, the outer surface of the vertical column longitudinal rib 11 of the embodiment is also provided with a sleeve 6, and the sleeve 6 is connected with the end parts of the upper connecting rod 2 and the lower supporting plate 4.
The connection relationship between the upper connecting rod 2 and the upper longitudinal rib 31 is preferably welded.
The fixing mode of the guard plate 5 is as follows: the guard plate 5 is connected to the lower surface of the lower support plate 4 through a screw 51, and the outer surface of the guard plate 5 is also provided with a sleeve plate 52.
Still be equipped with stirrup 12 between the inside vertical column longitudinal reinforcement 11 of side depressed part 13, this is because the horizontal pulling force that receives between the different vertical column longitudinal reinforcement 11 of this place is great to because the existence of side depressed part 13 can make the vertical column longitudinal reinforcement 11 the sectional area at this place reduce, consequently set up the integrative nature that multirow vertical column longitudinal reinforcement 11 connects at the number of times stirrup 12 of reasonable quantity.
In order to facilitate grouting, the grouting holes 34 of the present embodiment are preferably vertically arranged, and in order to ensure that mortar can be better filled to both sides of the open collar 41, in the present embodiment, when the end of the cross beam 3 is connected to the side recess 13, the lower end of the grouting hole 34 is connected to the inner edge of the open collar 41.
During installation, the guard plate 5 is fixed on the lower surface of the lower support plate 4, the lower longitudinal rib 32 is clamped inside the opening clamping sleeve 41 (the upsetting section 321 is completely positioned on the inner edge of the opening clamping sleeve 41) but is not contacted with the bottom of the opening clamping sleeve 41, the upper connecting rod 2 and the upper longitudinal rib 31 are arranged correspondingly at the moment, and the upper surface of the guard plate 5 is connected with the bottom of the cross beam 3. If the above requirements are not met for accuracy reasons, the position of the cross beam 3 can be adjusted appropriately, for example, by adding a shim plate between the upper surface of the shield 5 and the bottom of the cross beam 3.
Then the upper connecting rod 2 and the upper longitudinal rib 31 are welded, the side parts of the two sides of the side concave part 13 are sealed, for example, the sealing is carried out by adopting a template and other manners, after the sealing, under the action of the templates at the two sides and the bottom protection plate 5, a sealed cavity is formed, grouting operation is carried out near the welding position of the upper connecting rod 2 and the upper longitudinal rib 31, grout enters the vicinity of the opening cutting sleeve 41 from the grouting hole 34, because the lower end of the grouting hole 34 is connected to the inner edge of the opening cutting sleeve 41, and a certain gap is possibly formed between the end part of the cross beam and the side concave part 13, and partial grout can also possibly flow in the gap, so the grout can preferentially flow to the cavity between the opening cutting sleeve 41 and the upright post 1, after the cavity is filled, more grout can flow in the direction of the cross beam 3 by overflowing the opening cutting sleeve 41, and the grout discharge hole 501 can be blocked after the grout is continuously discharged, when the upper surface of the grout is flush with the upper surface of the beam 3, grouting can be stopped. Can dismantle template and backplate 5 after the thick liquid solidifies, will form reliable connection between the muscle 32 of indulging down this moment and the opening cutting ferrule 41, mortar 7 after solidifying simultaneously can be sealed the welding department of last connecting rod 2, the last muscle 31 of indulging, avoids this department to rust, and mortar 7 after solidifying surrounds at last muscle 31 of indulging, indulging down around muscle 32, the opening cutting ferrule 41, can become an organic whole with stand 1, crossbeam 2.
The utility model discloses a prior art middle standing pillar 1 provides a comparatively reliable connected mode with being connected of crossbeam 3 to connect reliably, simple structure.
