Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, which are illustrative of the present invention and are not to be construed as limiting the present invention.
As shown in fig. 1, a seamless construction method of an assembly type joint connection includes the following steps,
the method comprises the following steps: pre-embedding a splicing assembly 1 at the joint end of an assembled wallboard/floor slab/stair/balcony, wherein the splicing assembly is at least connected with main steel bars of the wallboard/floor slab/stair/balcony, or the main steel bars of the wallboard/floor slab/stair/balcony penetrate through the splicing assembly 1;
step two: building a template of an assembled wallboard/floor slab/stair/balcony, pouring concrete, detaching the template after the concrete is condensed, and transporting the template to a construction site after maintenance;
step three: hoisting an assembled wallboard/floor slab/stair/balcony, clamping and shrinking the embedded splicing assemblies on the assembled wallboard/floor slab/stair/balcony by using a clamping sleeve, then elastically riveting the embedded splicing assemblies for positioning, and loosening the clamping sleeve 3;
step four: elastic grouting 4 is filled in the embedded splicing assembly 1, and after the embedded splicing assembly is completely solidified, the site is cleaned and data is recorded.
Wherein the elastic grouting is one of water-based epoxy elastic grouting glue, silicon rubber and high-elastic polyurethane plugging grouting.
Example of the connection to the wallboard a based on the above steps:
as shown in fig. 1 and 2, the wall panel a is mainly affected by transverse tensile force. In actual operation, the splicing component 1 is a whole wedge-shaped riveting block, and is directly an elastic surface 11 with one surface or two surfaces (generally, the splicing component is provided with 4 connecting springs 12, and the front elastic force is greater than the rear elastic force of the connecting springs 12), during installation, the elastic surface is clamped and contracted by the clamping sleeve 3 through the screw hole of the sealing anti-seepage plate 2, so that one end of each connecting spring 12 is pressed against the splicing component, and the other end of each connecting spring is pressed against the elastic surface 11. The two splicing assemblies 1 spliced after being connected are mutually abutted, and deformation or crack water seepage and the like due to shearing force and small-amplitude settlement can be avoided under the action of elasticity.
For the sake of beauty and further preventing cracks from appearing, the elastic grouting is filled in the fourth step at the position of the gap between the connecting spring 12 and the elastic surface 11, and then the sealing impermeable plate is packaged on the surface of the gap, and the edge of the sealing impermeable plate is provided with a sealing ring 21. The sealing anti-seepage plate 2 is connected on the two splicing assemblies 1 which are mutually matched, and the sealing anti-seepage plate 2 is also used as a barrier for preventing corrosion.
Example of connection to floor b based on the above procedure:
as shown in figure 3, because the splicing component 1 is directly in the shape of being meshed up and down, it is worth saying that the clamping elastic surface 11 of the jacket 3 is not required to be contracted at this time, and the self gravity can be directly utilized. Particularly, the elastic grouting 4 is water-based epoxy elastic grouting glue, and the assembly 1 is spliced after grouting, so that the water seepage prevention effect is better. The position of filling the elasticity grout is the space between connecting spring 12 and elastic surface 11, and the sealed prevention of seepage board is sealed on its surface afterwards, is equipped with sealing washer 21 on sealed prevention of seepage board 2, and sealing washer 21 has increased the sealed area water-proof effects better for whole cover in sealed prevention of seepage board 2 bottom. The sealing anti-seepage plate 2 is connected on two splicing assemblies 1 which are mutually matched.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
