Problems solved by technology

[0004] Based on the above-mentioned background problems, the present invention aims to provide a kind of anti-leakage treatment process for reserved openings. The section steel of the overhanging scaffolding through the wall is pre-embedded at the reserved opening. After the overhanging scaffold through the wall is removed, the overhanging overhanging The scaffolding steel is removed, and then filled with precast concrete blocks. The gap between the precast concrete block and the original structure is filled with waterproof mortar, and the gap on the outside is sealed with a foaming agent. The problem of time-consuming and labor-consuming is solved, and the operation is convenient; another object of the present invention is to provide a kind of cantilevered scaffold steel

Embodiment 1

[0038] Cantilevered scaffold steel through the wall, such as Figure 1-3 As shown, the cantilevered scaffold section steel 1 through the wall is a frame structure surrounded by an upper branch 101 , a left branch 102 , a lower branch 103 and a right branch 104 .

[0039] In this embodiment, the upper branch 101 and the lower branch 103 are rectangular frame structures, and the left branch 102 and the right branch 104 are provided with protrusions, so that the cantilevered scaffold steel 1 formed by enclosing the wall is Cross frame structure.

[0040] It should be noted that the cantilevered scaffold section steel 1 through the wall is not limited to the cross frame structure, and in other embodiments, it can also be a rectangular frame structure or other shapes, because the cantilevered scaffold section steel 1 through the wall needs to be pre-embedded To the reserved hole, therefore, the shape and size of the cantilevered scaffold steel 1 through the wall need to be adjuste...

Embodiment 2

[0046] Concrete block molds for making precast concrete such as Figure 5-7 As shown, the concrete block mold 2 is made up of an upper mold 201 and a lower mold 202, as Figure 5 As shown, the upper mold 201 has a convex structure, and the lower mold 202 is provided with a protrusion opposite to the convex structure of the upper mold 201, so that the concrete block mold 2 has a cross frame structure.

[0047] The concrete block mold 2 is also not limited to the cross frame structure of the present embodiment, and it can be adjusted according to the shape of the reserved hole.

[0048] In order to facilitate the removal of the precast concrete block, the concrete block mold 2 of this embodiment is a detachable structure, that is, the upper mold 201 and the lower mold 202 are detachably connected, and the detachable structure is the same as that in the first embodiment.

[0049] In this embodiment, the upper mold 201 is provided with a first convex line 203, the first convex line...

Embodiment 3

[0052] The anti-seepage treatment process for reserved openings includes the following steps:

[0053] (1) if Figure 10 As shown, the original wall structure is provided with a reserved hole 4, and the wall-mounted cantilevered scaffold steel 1 is pre-buried at the reserved hole 4, and the wall-through cantilevered scaffold steel 1 is set close to the wall of the reserved hole 4;

[0054] (2) make prefabricated concrete block 3 according to the shape and size of reserved hole 4, the size of prefabricated concrete block 3 is 20mm smaller than the size of reserved hole 4, but not limited to this, specifically can be between 15-25mm Adjust; Prefabricated concrete block 3 specifically adopts the concrete block mold 2 in embodiment 2 to carry out the making of prefabricated concrete block 3, and maintains after prefabricated concrete block 3 demoulding;

[0055] (3) After the overhanging scaffolding through the wall is removed, if Figure 11 with 12 As shown, remove the cantile...

Abstract

The invention provides a reserved hole anti-leakage treatment process and wall-penetrating cantilever scaffold profile steel, and belongs to the technical field of building construction. The reserved hole anti-leakage treatment process comprises the following steps that the wall-penetrating cantilever scaffold profile steel is pre-buried in a reserved hole, and a prefabricated concrete block is manufactured according to the shape and size of the reserved hole; and after a wall-penetrating cantilever scaffold is dismantled, the wall-penetrating cantilever scaffold profile steel is dismantled, the prefabricated concrete block is placed into the reserved hole to be blocked, a gap between the prefabricated concrete block and the inner side of an original structure is filled with waterproof mortar, and a gap in the outer side is blocked with a foaming agent. According to the anti-leakage process, the anti-leakage requirement of an outer wall can be met, the problems of labor and time waste are solved to a great extent, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an anti-leakage treatment process for reserved openings. In addition, the invention also relates to a cantilevered scaffold section steel through a wall. Background technique [0002] Cantilevered scaffolding is a simple facility used in construction, mostly used in the construction of high-rise buildings. During the construction of cantilevered scaffolding, it is necessary to fix the pole through the wall in the floor, then tilt the other end of the pole outward and fix it, and set up a cross bar on the upper part and lay a scaffolding board to form a construction layer. In order to realize For the piercing of vertical poles, openings are generally reserved on the external wall or concrete wall. After the cantilevered scaffolding is removed, workers manually fill the reserved openings with masonry or expanded fine stone concrete to prevent leakage. ...
