The utility model discloses marking time sawtooth roof beam and folded plate and prefabricate respectively and install at the scene, sawtooth roof beam and folded plate mark time small, light in weight, the scale production of being convenient for has effectively reduced transportation and construction cost, and simple installation.
Description
Technical Field
The utility model relates to a prefabricated staircase component field especially relates to prefabricated roof beam and folded plate combination stair of marking time.
Background
The existing prefabricated stairways have the problem of overweight, the weight of the plate-type stairways or the beam-type stairways is 4-5 tons, and the weight of a lifting appliance is added, so that the common construction tower crane cannot meet the lifting weight requirement, and the tower crane needs to be upgraded or replaced, thereby increasing the overall cost.
Therefore, it is obvious that the above-mentioned existing prefabricated stairways still have inconveniences and disadvantages in structure, and further improvement is needed. How to create a new prefabricated beam and folded plate step combined stair belongs to one of the current important research and development subjects.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a precast beam and folded plate combination stair of marking time makes it small, light in weight, the transportation and the installation of being convenient for to overcome current precast stair's not enough.
In order to solve the technical problem, the utility model provides a precast beam and folded plate combination stair of marking time, mark time including sawtooth roof beam and folded plate, the sawtooth roof beam is prefabricated component with the folded plate is marked time, and the parallel opposition installation of sawtooth roof beam two or more, the upper and lower both ends connection of sawtooth roof beam is chosen between the ear at the cast-in-place of upper and lower floor, and the several folded plate horizontal connection of marking time is between the sawtooth roof beam, and the folded plate is marked time and is constituted combination stair with the sawtooth roof beam.
As an improvement of the present invention, the upper surface of the sawtooth beam is a stepped sawtooth-shaped rising surface, and the lower surface is a flat surface that rises obliquely.
Furthermore, the uppermost ladder of the sawtooth beam horizontally extends out of the upper connecting end, the upper connecting end is embedded into the cast-in-place lug of the upper floor and is fixedly installed, the lowermost ladder of the sawtooth beam horizontally extends out of the lower connecting end, and the lower connecting end is embedded into the cast-in-place lug of the lower floor and is fixedly installed.
Furthermore, the cross section of the folded plate step is L-shaped, the long edge of the L-shaped step is attached to the surface of the horizontal part of each step of the sawtooth beam to form a step plate, and the short edge of the L-shaped step is attached to the surface of the vertical part of each step of the sawtooth beam to form a kicking plate.
Further, the sawtooth beam is a reinforced concrete member.
After adopting such design, the utility model discloses following advantage has at least:
1. the prefabricated sawtooth beam is a plane component, so that the weight is light, and the common construction tower crane can meet the requirement;
2. the prefabricated folded plate step can be produced in large scale, the volume is small, and the folded plate step can be installed by two persons;
3. the prefabricated sawtooth beam and the prefabricated folded plate step component are small, the die is simple, the production is easy, the transportation is facilitated, and the transportation cost can be reduced.

The foregoing is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clear, the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.
Fig. 1 is a schematic structural view of the prefabricated beam and folded plate step combined stair of the present invention.
Fig. 2 is an installation schematic view of the precast beam and the folded plate step combined stair of the utility model.
Description of reference numerals: 1-a sawtooth beam; 2, folding a step; and 3-ear picking in situ.
Detailed Description
Referring to fig. 1 and 2, the utility model provides a precast beam and folded plate combination stair of marking time, including sawtooth roof beam 1 and folded plate 2 of marking time, sawtooth roof beam 1 and folded plate 2 of marking time are prefabricated component, the upper surface of sawtooth roof beam 1 is the ascending flat surface of ladder cockscomb structure, the lower surface of sawtooth roof beam 1 is the ascending flat surface of slope. An upper connecting end is horizontally extended from the uppermost layer step of the sawtooth beam 1, a lower connecting end is horizontally extended from the lowermost layer step, when the sawtooth beam is installed, the upper connecting end is embedded into a groove of the upper cast-in-situ cantilever lug 3 to be installed, the lower connecting end is embedded into a groove of the lower cast-in-situ cantilever lug 3 to be installed, and the two sawtooth beams 1 are installed between the upper cast-in-situ cantilever lugs 3 and the lower cast-in-situ cantilever lugs 3 in the installation mode. The folded plate step 2 is a flat plate component with an L-shaped section, the long edge of the L shape is attached to the surface of the horizontal section of the step of the sawtooth beam 1 to form a step plate, and the short edge of the L shape is attached to the surface of the vertical section of the step of the sawtooth beam 1 to form a step plate.
The utility model discloses a sawtooth roof beam 1 and folded plate are marked time 2 and are processed respectively in prefabricated in-process, at the site operation stage, install sawtooth roof beam 1 earlier and choose between ear 3 at the cast-in-place of upper and lower floor's stair, follow supreme each folded plate of installing in proper order down again and mark time 2, effectively reduce construction cost.
The above description is only for the preferred embodiment of the present invention, and not intended to limit the present invention in any way, and those skilled in the art can make various modifications, equivalent changes and modifications using the above-described technical content, all of which fall within the scope of the present invention.
