Problems solved by technology

[0003] In the prior art, because of the high pressure in the connecting chamber between the two prefabricated components, when high-strength mortar is injected into the grouting sleeve, the solidified and formed slurry around the connecting chamber is prone to damage and bursting occurs, while the grouting sleeve During grouting, the high-strength mortar continuously leaks from the burst chamber, which affects the construction progress and quality; resulting in incomplete grouting in the grouting sleeve, and the connection quality of the grouting sleeve cannot be guaranteed, which in turn affects the connection strength of prefabricated components
At present, there is a lack of simple, efficient, versatile and easy-to-operate construction methods for this technical problem.

Embodiment 1

[0033] see illustration figure 1 , the vertical construction node of the prefabricated component in this embodiment 1 includes the second prefabricated component 2 located below and the first prefabricated component 1 located above, the bottom side of the first prefabricated component 1 is pre-embedded with a grouting sleeve 3, and the grouting sleeve 3. One end is connected to the stressed rib 11 in the first prefabricated member 1, and the other end is provided with a reinforcing bar connection port (not shown in the figure); placed above the second prefabricated member 2 .

[0034] see illustration figure 2 , during installation, the stressed reinforcement 21 on the top side of the second prefabricated member 2 extends into the interior of the reinforcement connection port of the grouting sleeve 3 on the bottom side of the first prefabricated member 1 . An elastic seal is provided on the surface of the first prefabricated member 1 and at the edge of the second prefabrica...

Embodiment 2

[0043] The vertical construction node of the prefabricated member in this embodiment 2 includes the second prefabricated member 2 located below and the first prefabricated member 1 connected to the second prefabricated member 2 located above, which is different from the structure in Embodiment 1. in:

[0044] 1. The elastic seal in Embodiment 1 is arranged in the space formed by the seam between the first prefabricated member 1 and the second prefabricated member 2, and the outer edge of the elastic seal does not exceed the bottom edge of the first prefabricated member 1 (see signal figure 2 ), that is, the elastic seal is placed in the seam; and the elastic seal in Example 2 is arranged on the outer edge of the bottom side of the first prefabricated member 1, not in the seam space of the two prefabricated members (see the schematic diagram Figure 4 ).

[0045] 2. In Embodiment 1, the clip includes a steel plate 6 and a fixing piece. The steel plate 6 is arranged on the ou...

Abstract

The invention provides a vertical construction node for prefabricated members, comprising an upper first prefabricated member and a lower second prefabricated member, further comprising an elastic sealing element and a card, wherein the elastic sealing element is arranged at the edge of a seam between the first prefabricated member and the second prefabricated member, and the card is clamped at the periphery of the elastic sealing element. The invention also provides a construction method of the node, comprising the following steps: S1, hoisting, mounting and fixing the second prefabricated member, and arranging a spacer on the surface of the second prefabricated member; S2, hoisting the first prefabricated member to a predetermined position, and causing a top carrying bar of the second prefabricated member to stretch into a bottom grouting sleeve of the first prefabricated member; S3, arranging the elastic sealing element at the edge of the seam of the prefabricated members, and providing the card to fix the elastic sealing element; and S4, injecting high-strength mortar from a grouting opening of the grouting sleeve, and removing the card and the elastic sealing element after themortar is solidified. In this solution, a connected warehouse is unlikely to burst, the sealing element can be reused, the versatility is strong, and the construction steps are simple.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a construction method for vertical construction nodes of prefabricated components. Background technique [0002] In the construction of prefabricated buildings, prefabricated components can be connected by steel bars between adjacent prefabricated components through embedded sleeve grouting. The connection between the upper and lower prefabricated columns is taken as an example. By pre-embedding a grouting sleeve on the bottom side of the upper prefabricated column, the top of the grouting sleeve is anchored with the pre-buried stress steel bars in the upper prefabricated column, and the bottom end is provided with steel bars to connect mouth. During construction, the upper and lower prefabricated columns are assembled, and the reinforcement bars of the lower prefabricated components extend into the reinforcement connection ports at the bottom end of the grouting...
