Drawings

Fig. 1 is the utility model discloses in the embodiment of the utility model discloses belt landing stage steel truss and web member root and lower gusset plate protection device schematic structure.

In the drawings: 1. a web member root; 2. a lower gusset plate; 3. a belt; 4. trestle steel truss; 5. a step; 6. a first guard plate; 7. and a second protection plate.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustration and not for limitation of the present invention.

As shown in fig. 1, a belt landing stage steel truss web member root and lower gusset plate protection device, including the guard plate that is used for sealing web member root 1 and lower gusset plate 2, guard plate one end vertical fixation is subaerial in the landing stage, and on the other end was fixed in the landing stage lateral wall, was equipped with the hole of stepping down that supplies the web member to pass on the guard plate. Through setting up the guard plate, protect web member root 1 and lower gusset plate 2, avoid dashing dirt water and contact web member root 1 and lower gusset plate 2 to protection web member root 1 and lower gusset plate 2 do not receive the corruption, extension trestle steel truss 4 life.

Further, the guard plate includes first guard plate 6 and second guard plate 7, and 6 vertical settings of first guard plate, second guard plate 7 are the inclined plane setting, and the seamless concatenation of 7 tip of first guard plate 6 and second guard plate. Second guard plate 7 that the inclined plane set up is unfavorable for moisture to be saved, consequently dashes that dirt water can slide down to ground along the inclined plane fast after splashing on second guard plate 7, and is preferred, and second guard plate 7 sets up the radius angle with 6 concatenation departments of first guard plate, increases construction place's security performance, avoids simultaneously towards dirt water and remains in concatenation edge. The tip that 6 concatenation sides of first guard plate were kept away from to second guard plate 7 is fixed on the landing stage lateral wall through the fixed strip of wiping of side rock wool board, guarantees the sealing performance of second guard plate 7.

Further, the first protection plate 6 is a concrete water retaining platform. Concrete manger plate platform can set up to an organic whole form with the subaerial step 5 of bottom to avoid first guard plate 6 not enough with ground sealing performance, because step 5 also is the concrete material, the same material concatenation has the same deformation volume, therefore receives external environment to disturb and the probability that produces the gap can reduce, concrete manger plate platform is sturdy and durable simultaneously, and with low costs and waterproof performance is good, the perpendicular to ground setting, and in cleanness and maintenance.

Further, the vertical height of the first protection plate 6 is 350-450 mm.

Further, the vertical height of the first shielding plate 6 is 400 mm. The first protection plate 6 is arranged at a height consistent with that of the belt 3, and the water spray only involves splashing phenomenon above the belt 3, so that a second protection plate 7 capable of allowing splashed water to flow out needs to be arranged above the first protection plate 6.

Further, the second protection plate 7 is a color plate water baffle, a stainless steel water baffle, an aluminum alloy water baffle, an ABS water baffle or a PVC water baffle. The second protective plate 7 only plays a role in sealing and retaining water, and a certain water retaining shape is required, so that a plate which is easy to mold and is corrosion-resistant is selected.

Furthermore, the hole of stepping down sets up on second guard plate 7, and the downthehole gasket that is used for sealed hole and the web member of stepping down that is equipped with of stepping down. The second protection plate 7 and the web member are sealed by the sealing sheet, so that dust flushing water is prevented from flowing into the yielding hole.

Further, the sealing piece is a silica gel sealing piece or a rubber sealing piece. Choose for use soft silica gel gasket or rubber gasket, easily moulding, it is corrosion-resistant, can avoid second guard plate 7 or web member vibrations to lead to sealed inefficacy simultaneously.

Furthermore, the sealing sheet is connected with the abdicating hole and the web member in a sealing manner through sealing glue. Sealed effect of gluing makes the guard plate form waterproof room below the web member for under gusset plate 2 and web member root 1 be in the dry environment, as the optimization, under gusset plate 2 and web member root 1 in the guard plate set up in the air, the top no longer uses the concrete to harden and covers, after removing the concrete hardening overburden that possesses the water retention effect, even there is a small amount of water or moist air entering enclosure space, can leak immediately or give off to outdoor, the member is in the dry environment for a long time, difficult corrosion, the corruption.

Furthermore, the second protection plate 7 is spliced at the upper end of the first protection plate 6 in an arc inclined plane. The tangent line of the arc end part of the second protection plate 7 is vertical, so that the second protection plate is seamlessly spliced with the first protection plate 6. Preferably, 7 arc lower terminations of second guard plate have with the extension board that 6 faces of first guard plate are parallel, during the installation, the lateral surface setting of first guard plate 6 is hugged closely to the extension board, and the lower extreme height of extension board is less than belt 3 and sets up the height, further avoids making out the infiltration of dirt water from first guard plate 6 and 7 joints of second guard plate.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
