Description

Technical Field

[0001] The utility model belongs to the technical field of tower crane protection devices, and more specifically, particularly relates to a lattice tower crane foundation water cut-off device. Background Art

[0002] At present, lattice tower cranes are more and more widely used in the field of construction engineering. The main structure of the lattice tower crane foundation is to lift the reinforced concrete pedestal above the basement roof, and insert steel lattice columns into the concrete piles. Therefore, the anti-corrosion protection of the steel lattice columns is the key to ensure the safe use and construction of the tower crane. During the construction process, rainwater will flow down to the bottom along the lattice tower crane foundation pedestal. It is inevitable that a large amount of rainwater will flow into the basement and cause corrosion to the steel lattice columns. At present, the conventional practice of the tower crane foundation is unorganized drainage, and anti-rust paint is applied to the tower body to achieve anti-corrosion effect. This practice cannot avoid contact with a large amount of rainwater, and there is still a risk of corrosion for a long time. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a lattice tower crane foundation water cut-off device. By arranging the device at the lower part of the tower crane foundation bearing platform, it can not only solve the problem of unorganized drainage of rainwater on the existing tower crane foundation bearing platform, but also drain the rainwater on the tower crane bearing platform into the water cut-off device, thereby greatly reducing the contact between the steel lattice column and the rainwater, having good airtightness, and effectively reducing the rust of the steel lattice column.

[0004] The purpose and effect of the utility model of a lattice tower crane foundation water cut-off device are achieved by the following specific technical means: a lattice tower crane foundation water cut-off device, comprising a bearing platform;

[0005] The interior of the load-bearing platform is reinforced concrete, and four steel lattice columns are fixedly installed on the lower end surface of the load-bearing platform;

[0006] A water cut-off plate, wherein the main body of the water cut-off plate is a U-shaped structure, the cross section of the water cut-off plate is a U-shaped structure, and each outer end surface of the water cut-off plate is respectively equipped with two drainage pipes;

[0007] A water retaining plate, the water retaining plate is fixedly mounted on the upper end surface of the vertical plate at the outer end of the water cut-off plate;

[0008] A connecting plate, the connecting plate being fixedly mounted on the upper end surface of the inner end vertical plate of the water cut-off plate;

[0009] The lower end of the steel wire rope is bound in the through hole on the surface of the water retaining plate, and the upper end of the steel wire rope is bound in the fixing ring at the upper end of the fixing block.

[0010] Furthermore, four groups of fixing blocks are fixedly installed on the upper end surface of the load-bearing platform, and fixing rings are fixedly installed on the upper end surfaces of the fixing blocks.

[0011] Furthermore, the water baffle body is an inclined structure, the angle between the water baffle and the horizontal plane is forty-five degrees, and two through holes are provided on the surface of the water baffle.

[0012] Furthermore, fixing holes are evenly opened on the surface of the connecting plate, and the connecting plate is located on the lower end surface of the load-bearing platform. Screws pass through the fixing holes to fix the connecting plate on the lower end surface of the load-bearing platform. There is a distance of one centimeter between the outer end surface of the connecting plate and the outer end surface of the load-bearing platform, and the drainage pipe is connected to the water pipe.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, fixing holes are evenly opened on the surface of the connecting plate. Workers fix the connecting plate to the lower end surface of the load-bearing platform by screws, so as to fix the inner end of the water cut-off plate. The upper end of the steel wire rope is bound to the outside of the fixing ring, and the lower end of the steel wire rope is bound to the through hole on the surface of the water retaining plate. The steel wire rope can exert an upward pulling force on the outer end of the water cut-off plate, so as to improve the stability of the water cut-off plate.

[0015] A drainage pipe is fixedly installed on the outer end face of the water interception plate. Workers can connect a water pipe to the outside of the drainage pipe, and then the water outlet of the water pipe is located inside the drainage ditch to achieve the effect of water interception and drainage. It can prevent rainwater from dripping into the soil under the load-bearing platform, greatly reducing the contact between the steel lattice column and rainwater, and effectively slowing down the corrosion rate of the steel lattice column.

[0016] By fixing an inclined water retaining plate on the upper surface of the outer end side plate of the water cut-off plate, the rainwater interception effect can be improved, allowing rainwater to flow into the water cut-off plate along the water retaining plate. Two through holes for passing steel wire ropes are also provided on the surface of the water retaining plate, which facilitates workers to fix the steel wire ropes on the outside of the water retaining plate.

[0017] By setting a one-centimeter distance between the outer end surface of the connecting plate and the outer end surface of the load-bearing platform, workers can use waterproof sealant to seal it, which can improve the waterproof performance and prevent rainwater from penetrating into the interior of the connecting plate.
