Abstract
The utility model provides a kind of shaped steel hole prefabricated section through walls, including concrete precast block, and I-shaped reserves sealing, I-steel, and groove reserves sealing and channel-section steel, and described I-shaped is reserved sealing and is opened in concrete precast block；Described groove is reserved sealing and is opened in concrete precast block；It is intraoral that described I-steel is applied in I-shaped preset slot；It is intraoral that described channel-section steel is applied in groove preset slot.The purpose of this utility model is when ensureing that the section bars such as I-steel pass through concrete wall, reduces the damage to concrete wall, while reduces later stage patch work, saves time and cost of labor.
Description
Technical field
The utility model belongs to architectural engineering construction technique field, more particularly to a kind of shaped steel hole prefabricated section through walls.
Background technology
The builder's jack at building engineering construction scene is by the way that I-steel or channel-section steel are fixed on into building through shear wall
Internal structure, support is formed to carry upper falsework load using the part for building of encorbelmenting, therefore, is inevitably needed
Will be in position reserving hole through walls.In pre-buried one square template box of shear wall formwork plate stage, then usual way is
Casting concrete forms reserving hole, and the construction later stage needs to remove template at this, and needs special repairing hole, adds construction
Cost and engineering time, deficiency in economic performance.
Therefore, invent a kind of shaped steel hole prefabricated section through walls and seem very necessary.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of shaped steel hole prefabricated section through walls, existing to solve
Hole prefabricated section through walls concrete wall structure is damaged it is larger, the problem of relatively elaborate during work and inconvenient operation.One
Kind shaped steel hole prefabricated section through walls, including concrete precast block, I-shaped reserve sealing, I-steel, and groove reserves sealing and channel-section steel, institute
The I-shaped stated is reserved sealing and is opened in concrete precast block；Described groove is reserved sealing and is opened in concrete precast block；Institute
It is intraoral that the I-steel stated is applied in I-shaped preset slot；It is intraoral that described channel-section steel is applied in groove preset slot.
Preferably, described concrete precast block uses the concrete of the pouring molding in advance with floor label.
Preferably, described I-shaped reserves sealing and the dimension of opening of the reserved sealing of groove is arranged in builder's jack scheme
The I-steel of selection or the size of channel-section steel expand outwardly 20mm.
Preferably, hollow out is set from outward flange size (concrete precast block effective thickness) inside described concrete precast block
30mm is set to 35mm.
Preferably, I-shaped reserves sealing in described concrete precast block and groove is reserved in sealing and clogs cystosepiment, is used in combination
Adhesive tape closes two ends.
Compared with prior art, the utility model has the advantages that：Because a kind of shaped steel of the present utility model is worn
Wall opening prefabricated section is widely used in architectural engineering construction technique field.Meanwhile the beneficial effects of the utility model are：
1. in the utility model, described concrete precast block uses the coagulation of the pouring molding in advance with floor label
Soil, advantageously reduce and concrete wall structure is damaged.
2. in the utility model, described I-shaped reserves sealing and the dimension of opening of the reserved sealing of groove is arranged to pin hand of encorbelmenting
The I-shaped that the I-steel or the size of channel-section steel selected in frame scheme is expanded outwardly described in 20mm reserves sealing and groove reserves sealing
The size that dimension of opening is arranged to the I-steel or channel-section steel selected in builder's jack scheme expands outwardly 20mm, advantageously ensures that
Later stage I-steel or channel-section steel pass through.
3. in the utility model, from outward flange size, (concrete precast block has hollow out inside described concrete precast block
Effect thickness) 30mm to 35mm setting is arranged to, be advantageous to ensure prefabricated section overall integrity.
4. in the utility model, I-shaped reserves sealing in described concrete precast block and groove is reserved in sealing and clogs foam
Plate, blend compounds band close the setting of two ends, are advantageous to strengthen the stability of the built-in fittings such as I-steel.

Embodiment
The utility model is described further below in conjunction with accompanying drawing：
Embodiment：
As shown in accompanying drawing 1 to accompanying drawing 4
The utility model provides a kind of shaped steel hole prefabricated section through walls, including concrete precast block 1, I-shaped reserve sealing 2,
I-steel 3, groove reserve sealing 4 and channel-section steel 5, and described I-shaped is reserved sealing 2 and is opened on concrete precast block 1；Described groove
Reserved sealing 4 is opened on concrete precast block 1；Described I-steel 3 is applied in I-shaped and reserved in sealing 2；Described channel-section steel 5
Groove is applied in reserve in sealing 4.
In above-described embodiment, specifically, described concrete precast block 1 is using the pouring molding in advance with floor label
Concrete.
In above-described embodiment, specifically, described I-shaped reserves sealing 2 and the dimension of opening of the reserved sealing 4 of groove is arranged to
The I-steel 3 or the size of channel-section steel 5 selected in builder's jack scheme expands outwardly 20mm.
In above-described embodiment, specifically, (concrete is pre- from outward flange size for the described inside hollow out of concrete precast block 1
The effective thickness of clamp dog 1) 30mm is arranged to 35mm.
