Product Description:

Stair Tower


The structure of ring-lock stair tower is the same as Φ60 ring lock scaffolding.


The dimension of cross section is 1500×3000mm.It is widely used in construction.


Bearing Capacity of Stair Tower:


The stair tower can be erected with the maximum height of 150m,


when attached to the wall every 4.5m.

Q:What are the special construction plans for the rainwater tank culvert project?
General factory roof do mineral wool, sandwich tile seems to be through the fire, the wall is generally used a single layer of tile
Q:1 cubic tap water there is no way to reduce the water temperature to 15-18 degrees
Not very clear, continue to learn it hope my answer can help you, do not reward, as long as you top me.
Q:Construction of the project more than the number of layers must be used construction elevator
A does not affect the claim clause B does not affect the existence of the provisions of the dispute on the settlement of the dispute C
Q:There are several special construction projects in the construction project?
What is the exterior scaffolding erection specification? What do you need to pay attention to?
Q:How is the tower crane on the site raised?
1. Difference is not the mainstream of the heat dissipation heat sink + cooling fan, just based on the vacuum heat plate cooling technology VaporChamber. 2. From the heat side is still based on the vacuum plate is better. But based on vacuum hot plate cooling technology VaporChamber if the design is not good, but play a counter-effect. 3. If the price gap is not large, buy 5770 based on VaporChamber. The performance of the heat should be better.
Q:How to enter the tower on the operating room
Tower crane is the most significant tower crane center to the hook to reach the farthest distance, the specific is the car in the tower arm can run long distance. The working range of the tower crane is the radius of the tower crane, and the maximum distance from the crane to the center of rotation should meet the needs of the construction plane. The lifting height of the tower shall not be less than the total height of the building plus the height of the components, sling and safe operation (usually 2 to 3 m), and shall meet the scaffolding, derrick or other barrier material beyond the top of the building Generally not less than 1m) of the maximum beyond the height required. Tower crane in the minimum amplitude from the maximum weight, with the increase in the amplitude of the corresponding reduction in weight. Therefore, in a variety of amplitude are rated from the weight. Different amplitude and the corresponding weight together, can be drawn into a crane performance curve. Rated weight * distance from the center of the trolley = rated lifting moment. The balance of the general tower crane arm is greater than the maximum torque, the crane itself is a boom and balance arm unbalanced steel structure, this imbalance is based on the balance. Since the torque generated by the balance arm is large, that is, in the case of no hanging matter, plus the maximum wind load torque is the tower crane overturning moment. Rectangular basic check, the basic moment is the diagonal direction of the largest, in order to reinforcement. The maximum lifting torque is obtained without considering the wind load, theoretically, to achieve a very dangerous. The lifting weight of the tower crane should include the lifting material, spreader and rigging, etc. acting on the lifting crane hook crane all the weight. The lifting torque of the crane is generally controlled at 75% of its rated lifting torque to ensure safe operation and to extend its service life.
Q:Safety Management of Winter Construction Rules for Construction Engineering
Generally take 30 to 35 on it, low hardness is not enough, the cost is too high
Q:Seek building interior decoration safety information, full set! The The The The The The The The The The The The 1
Extrusion board is mainly produced according to the order, the amount can be more effective control of production costs, the amount is too low, then most manufacturers will not boot production, the more common domestic extruded board equipment, about 170 cubic meters to 250 cubic meters , If you do not have a lot of batches, then you can choose to buy the manufacturer's inventory products.
Q:Brief description of what is the danger source of the squad leader
The two kinds of sheet metal forming process is not the same Polyphenylene plate is made of volatile liquid blowing agent of the polystyrene beads, after heating preheated in the mold after heating with a fine closed-cell structure. Breaking the look will be a grain of grain. Usually white extruded plate It is made of polystyrene resin and other additives by extrusion process has a continuous uniform surface and closed-cell honeycomb structure of the plate. More brittle, but also deformation. All kinds of colors are, because the manufacturers in order to distinguish between their own brand to add something.
Q:What kind of jobs are the construction workers in the labor service network of the China Construction Service Network?
Generally small diameter of the socket more, large diameter welding or hot sets But no matter what way to connect, backfill quality is the most critical, especially for this flexible tube, backfill quality is not good, can easily lead to the control of muscle 碃 crown degree of protection Especially for large diameter pipes, backfill quality, in order to ensure the ring stiffness of the pipeline to reduce deformation and damage
