Background
In order to adapt to the construction of complex super high-rise buildings, the application of the whole steel platform formwork system is more and more extensive. A steel platform formwork system generally includes a steel platform system, a scaffolding system, a creel support system, a climbing system, and a formwork system. The steel platform system is located the top of structure, mainly carries the region as piling, and the entrance to a cave is many on the steel platform, if use traditional railing as safety protection, can occupy a large amount of heap and carry the space. Particularly, in the opening above the concrete wall, on-site construction personnel need to vertically transfer the reinforcing steel bars and pour concrete from the steel platform through the opening, and cannot be covered by a cover plate or surrounded by a railing.
The mode of band steel and twist steel is adopted in current entrance to a cave protection grid plate preparation, because each part wall body thickness of building structure is different, for satisfying the different distances of entrance to a cave, the grid plate can be according to the various specifications of entrance to a cave width design preparation, and the cost is slightly higher.
SUMMERY OF THE UTILITY MODEL
The utility model discloses problem and not enough to prior art exist provide one kind and be applicable to the anti-falling grid board above the steel platform entrance to a cave, can replace current protection grid board according to entrance to a cave width customization specification, constructor both accessible grid board also can satisfy the workman walking by the downward vertical transmission reinforcing bar of steel platform and concreting, have increased the steel platform and have piled year and usage space. Through the concatenation of two different length grid plates for the opening of grid plate can adapt to various different distances, and single grid plate can be packed up, and it is convenient to carry and transport, has saved the space. The utility model discloses component convenient to use is applicable to the entrance to a cave of arbitrary width, can retrieve used repeatedly completely, practices thrift the cost, has improved the efficiency of construction.
The utility model discloses a solve above-mentioned technical problem through following technical scheme:
the utility model provides an entrance to a cave grid plate for steel platform protection, its characteristics lie in, it includes two grid plates of splicing mutually, every the grid plate includes the rectangle grid plate frame that comprises four angle irons, rectangle grid plate frame internal fixation has the net piece, the net piece comprises the round steel that twists reverse of horizontal direction and the round steel that twists reverse of vertical direction, two the adjacent minor face of grid plate is connected with the connecting plate to the both ends through bolt fastening connecting plate and the adjacent minor face of the grid plate that corresponds.
Preferably, the angle steel and the torsion round steel are made of low-carbon alloy steel.
Preferably, the transverse direction torsion round steel and the vertical direction torsion round steel are welded to form a net sheet, and the net sheet is welded to the rectangular grid plate frame.
Preferably, the length of the short side of the rectangular grid plate frame is 300mm or 600 mm.
On the basis of the common knowledge in the field, the above preferred conditions can be combined at will to obtain the preferred embodiments of the present invention.
The utility model discloses an actively advance the effect and lie in:
1. the utility model provides a grid board makes constructor both accessible grid board by the downward vertical transmission reinforcing bar of steel platform and concreting, also can satisfy the workman and walk, has increased the steel platform and has piled year and usage space.
2. The utility model discloses can replace the protection grid board that has now according to entrance to a cave width customization specification, grid board dismouting, use, transportation convenient to carry, the concatenation through different specification grid boards is applicable to the entrance to a cave of arbitrary width, can retrieve used repeatedly completely, practices thrift the cost, has improved the efficiency of construction.
Drawings
Fig. 1 is a schematic structural view of an opening grid plate for protecting a steel platform according to a preferred embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the embodiment provides an entrance to a cave grid plate for steel platform protection, it includes two first grid plate 1 and the second grid plate 2 of splicing mutually, first grid plate 1 and the second grid plate 2 all include the rectangle grid plate frame 3 that constitutes by four angle steel, welding has net piece 4 in the rectangle grid plate frame 3, net piece 4 is formed by the torsion round steel of transverse direction and the welding of the torsion round steel of vertical direction, the adjacent minor face angle steel of first grid plate 1 and the second grid plate 2 is connected with connecting plate 5 to the both ends through 6 fixed connection boards 5 of bolt and the adjacent minor face angle steel of the grid plate that corresponds, the angle steel all adopts low carbon alloy steel with the torsion round steel.
The short edge specification of the rectangular grid plate frame is generally 300mm and 600mm, the long edge specification is preset to be a plurality of types according to the distance of a reserved hole above a common concrete wall, and a hole is formed in the short edge angle steel on one side; the torsional round steel is welded on the rectangular grid plate frame 3 according to a certain distance to form the net piece 4, and compared with the common steel bars, the anti-skidding performance is better, and the distance can ensure that workers can normally work and walk.
When the grid plate is used, the two grid plates are selected to be spliced according to the width of the opening, and are horizontally fixed by the connecting plate and the bolts. The whole grating plate is arranged on the steel platform steel beam, is spliced along the through length of the upper opening of the wall body, is positioned on the same horizontal plane with the upper cover plate of the steel platform, avoids the protruding plane from being unfavorable for the walking of workers, is convenient for the walking and the working of the workers, and improves the construction safety. The hollow square lattice transmission reinforcing steel bar of the grating plate is used for improving the construction efficiency during the construction of workers. After the use, the two grid plates can be screwed and loosened, the bolts are separated, the carrying and the transportation are convenient, and the grid plates can be completely recycled and reused.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
