Description
Technical field
The utility model is related to a kind of prefabricated stringer type stairway of lightweight concrete light-gauge steel section.
Background technology
One of basic component essential in building structure during stair, the stair of various fancy also emerge in an endless stream.
And it is current, for the stair of concrete structure, cranked slab stairs is relatively conventional.But for cranked slab stairs, though prefabricated it can form,
Scantling is larger, and also therefore the deadweight of component is larger, for vast rural area, does not possess traffic condition typically.
The content of the invention
The purpose of this utility model is to provide a kind of prefabricated stringer type stairway of lightweight concrete light-gauge steel section, with overcome it is above-mentioned not
Foot.
To achieve the above object, technical solution of the present utility model is：A kind of lightweight concrete light-gauge steel section precast beam
Formula stair, including terraced beam, step plate and landing slab, the terraced beam include the concrete layer of light-gauge steel section and parcel light-gauge steel section,
The terraced beam two ends reserve one section of light-gauge steel section and stretch out concrete layer, and the terraced beam upper surface is hierarchic structure, and the terraced water per step
Plane is provided with preformed hole, and the step plate and landing slab are equipped with steel bar end, and the steel bar end is corresponding with the preformed hole, marks time
Plate and landing slab are fixed with terraced beam respectively.
Further, in the sheet forming of the step plate and landing slab for precast slab or modeling plank or plank
One or more combination.
Further, the concrete layer is lightweight concrete layer, and it is rectangle, circle, Z that the light-gauge steel section, which includes section,
Shape, H-shaped or U-shaped light-gauge steel section.
Further, it is marked with lightweight concrete in rectangle or the Circular Thin shaped steel.
The beneficial effects of the utility model are：1. main bearing member ladder beam use light-gauge steel section concrete, stair intensity,
Rigidity can reach security requirement；2. main material is lightweight concrete, light-gauge steel section and sheet forming, thus the deadweight of stair
Gently, cost is low, and single component is small, is readily transported；3. suitable assembled architecture, particularly rural area low layer assembled architecture.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
In figure：1-terraced beam, 2-step plate, 3-landing slab, 4-light-gauge steel section reserves section, 5-floor beam, 6-wall,
7-light-gauge steel section, 8-concrete layer, 9-steel bar end, 10-preformed hole, 11-mortar.
Embodiment
The utility model and its embodiment are described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 to Fig. 2, the utility model includes terraced beam 1, step plate 2 and landing slab 3, and terraced beam includes the He of light-gauge steel section 7
The concrete layer 8 of light-gauge steel section is wrapped up, the terraced two ends of beam 1 reserve one section of light-gauge steel section 7 and stretch out concrete layer 8, form thin-walled
Shaped steel reserves section 4, is connected with floor beam 5 or the grade structural elements of wall 6, and not only stress is reliable, also enhances the globality in house
Energy.The terraced upper surface of beam 1 is hierarchic structure, and terraced horizontal plane is provided with preformed hole 10 per step, and step plate 2 and landing slab 3 are all provided with
There is steel bar end 9, the steel bar end 9 is corresponding with the preformed hole 10, by the perfusion mortar 11 in preformed hole 9, make the peace of step plate 2
Platen 3 is fixed with terraced beam 1 respectively.The utility model reserves terraced beam 1 step plate 2 of monolithic, the embedded bar of landing slab 3 first 9
Corresponding hole, during installation, enters joining line with the mode of grouting by the two, becomes an entirety --- stair.
Step plate 2 and landing slab 3 can be one kind in the sheet forming of precast slab or modeling plank or plank
Or multiple combinations.Terraced beam 1 is prefabricated beams of concrete, and concrete used is lightweight concrete, and light-gauge steel section used can be section
For rectangle is circular or Z-shaped or the light-gauge steel section of the form such as H-shaped or U-shaped, if the closing form such as rectangular cross-section or circle is thin
Also injection lightweight concrete is needed to increase intensity in wall-shaped steel, light-gauge steel section.The utility model is stringer type stairway, terraced beam 1 and will be stepped on
Walk plate 2, landing slab 3 and separate prefabricated, and use light-gauge steel section and lightweight concrete, solve scantling it is big, from great, be not easy to
The problem of transport.
The beneficial effects of the utility model are：1. main bearing member ladder beam use light-gauge steel section concrete, stair intensity,
Rigidity can reach security requirement；2. main material is lightweight concrete, light-gauge steel section and sheet forming, thus the deadweight of stair
Gently, cost is low, and single component is small, is readily transported；3. suitable assembled architecture, particularly rural area low layer assembled architecture.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
