This utility model discloses a supporting vertical rib and steel truss bottom formwork reinforcement assembly for building construction, including a supporting vertical rib disposed at the top of the steel truss bottom formwork: a thickened hollowed-out part is welded to the inner cavity of the supporting vertical rib, and a perforated angle iron is provided at the top of the steel truss bottom formwork. A positioning bolt is threadedly connected to the inner cavity of the perforated angle iron, and the perforated angle iron is fixedly connected to the steel truss bottom formwork by the positioning bolt. A large-diameter bolt is threadedly connected to the inner cavity of the perforated angle iron, and the surface of the rear end of the large-diameter bolt penetrates through the thickened hollowed-out part to the rear side of the supporting vertical rib. By using the combination of the thickened hollowed-out part and the perforated angle iron, this utility model can provide additional support to the inner cavity of the supporting vertical rib and increase the connection force between the supporting vertical rib and the steel truss bottom formwork, thereby achieving the purpose of reinforcing the connection between the supporting vertical rib and the steel truss bottom formwork and making the connection between the supporting vertical rib and the steel truss bottom formwork more secure.

The utility model provides a new open larger hole reinforcing structure of existing prefabricated hollow floor, when construction, before the new open larger hole and the hole of grouting material grouting hole of plate top, the front and rear and the left and right of new open larger hole position of the top surface and the bottom surface of existing prefabricated hollow floor and the front and rear and the left and right of hole of grouting material grouting hole position of plate top are all provided with reinforcing plate and reinforce, and the joint position of reinforcing plate all adopts the connection and fixation of opposite pull bolt, then the new open larger hole and the grouting hole of grouting material of plate top are set up, and the grouting material is filled into the hollow hole of existing prefabricated hollow floor through the grouting hole of grouting material of plate top. The utility model can reinforce the circumferential part of new open larger hole position, ensure the reliable firmness of reinforcement, reduce construction engineering quantity and construction difficulty, speed up construction speed and reduce construction cost.

The present application discloses a rainbow color white glaze base material, a glaze slurry, a glaze surface, a glaze surface product and a preparation method. The present application does not use traditional harmful elements such as lead and vanadium as the formula of the rainbow color glaze. After high-temperature sintering treatment, the rainbow color white glaze surface can be successfully obtained. By controlling the microstructure of the glaze layer and the glaze formula, the harm to human beings and nature during production and use is greatly reduced.

A disposable absorbent article having a transverse axis X and a longitudinal axis Y. The disposable absorbent article comprises a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorbent core, the disposable absorbent article further comprises a wing portion, the wing portion comprises at least one main wing panel, at least one first auxiliary wing panel and at least one second auxiliary wing panel, the first auxiliary fin extends along a first imaginary line and has a first angle of the first imaginary line relative to the transverse axis X. The second auxiliary fin extends along a second imaginary line and has a second angle of the second imaginary line relative to the transverse axis X. The first auxiliary wing piece and the second auxiliary wing piece which have a certain inclination degree relative to the transverse axis are arranged on the basis of the main wing piece and are used in cooperation with the fixing area, the upper portion, the middle portion and the lower portion are jointly positioned, the area of the wing portions fixed to the surface of the underpants is increased, the fixing effect of the wing portions is guaranteed, and the phenomena of displacement, wrinkling, turnover and the like of the sanitary towel are avoided. And the leakage-proof performance of the sanitary towel is further improved.

The invention discloses a construction method for one-time forming of an ultra-wide reinforced concrete stair, which comprises the following steps: step 1, preparation before construction: paying off the stair according to a design drawing; secondly, a stair bottom formwork and stair side formworks are installed; thirdly, binding of a reinforcing mesh is completed; fourthly, a kicking surface formwork is installed at the step section of the stair; fifthly, a supporting plate is installed on the outer side of each kicking face formwork; sixthly, a supporting base is installed at the bottom of the supporting plate; seventhly, a positioning clamp for limiting the supporting plate is installed; 8, a connecting plate is mounted at the top of the supporting plate; and ninthly, concrete is poured, the formwork is removed after the concrete meets the design requirement, and by means of the construction method, the straightness of step forming can be guaranteed, and the construction quality of stairs is guaranteed.

A surface treatment device for gear processing with convenient loading and unloading is disclosed. This utility model relates to the field of gear processing technology. A support platform is set inside the processing box, and a base is set on the lower side of the support platform. The base is fixedly set on the output shaft of a rotary motor. There are two sliding columns, which slide through the sliding grooves opened opposite each other in the support platform. A positioning column is set at the upper end of the sliding column. The drive motor is fixedly set on the upper middle part of the base through a motor bracket, and a driving bevel gear is set on the output end of the drive motor. There are two driven bevel gears, which are meshed on the left and right sides of the driving bevel gear. There are two transmission screws, which are fixedly set on the outer end of the transmission shaft. The transmission screws are threaded through the corresponding sliding columns. By tensioning the holes and grooves inside the gears, the gears are kept in a fixed state, which not only ensures the stability during processing, but also simplifies the operation and improves the operating efficiency.
