The invention relates to an improvement of staple channel giving structure of the nail beater. It contains an external slot, a guiding cover and an inner slot. The external slot is located on the gun body and has parallel first sidewall and second sidewall, each of them has a guiding slot. The front end of the first sidewall has a gap connecting with the guiding slot. The guiding cover is equipped on the external slot and it forms a supporting end to support T staples corresponding to the gap of the first sidewall. The inner slot locates between the two sidewalls to push the T staples. Therefore, the inner slot has two guiding plates which are parallel with the two sidewalls. The baffles within one level are set on both sides of the two guiding plates. A good effect of giving staples is realized and the service life is prolonged. In addition, it avoids striking two T staples.

The present invention provides a bearing wall with a low specific gravity of as low as 1.0 or less and a wall-magnification of 2.5 or more, which is excellent in strength, fire-safety, workability, dimensional stability, freezing resistance, water resistance and earthquake resistance, and a method for manufacturing the board. The board is produced by a method that contains the steps of: preparing a slurry by dispersing a cement-based hydraulic material, a fiber reinforcing material and a lightweight aggregate into water, adding a saturated carboxylic acid to the slurry, and then forming the slurry into a sheet, dehydrating the sheet, pressing the sheet and curing the sheet. The cement-based hydraulic material is contained in an amount of 20 weight% or more, and 60 weight% or less, based on the total solid content; the fiber reinforcing material is contained in an amount of 6 weight% or more, and 20 weight% or less, based on the total solid content; and the lightweight aggregate is contained in an amount of 3 weight% or more, and 18 weight% or less, based on the total solid content; and the saturated carboxylic acid is contained in an amount of 0.1 weight% or more, and 2.0 weight% or less, based on the total solid content. The fiber reinforcing material includes a refined fiber with a freeness of 650 ml or less and an unrefined fiber. The saturated carboxylic acid is a stearic acid-based carboxylic acid or a succinic acid-based carboxylic acid.

The invention discloses a nailing clamp for slots, and belongs to the field of disassembling and assembling tools for the slots. The nailing clamp for the slots comprises a holding portion, a rotatingshaft and a clamp head, and the clamp head comprises wire shearing portions, clamping portions and force-assisting arms arranged between the wire shearing portions and the clamping portions, whereinthe wire shearing portions are connected with the rotating shafts; the wire shearing portions are arranged on the upper portions of the force-assisting arms, and the clamping portions are arranged onthe lower portions of the force-assisting arms. The nailing clamp has the advantages of being safe to operate and achieving convenience and rapidness for nailing on the slots.

The invention relates to an automatic nailing mounting vehicle of a stainless steel push-and-pull door frame pocket. The mounting vehicle comprises a walking device, two rotating devices and nailing devices; the two rotating devices are symmetrically mounted above the walking device and are arranged in a back-to-back manner, and one nailing device is arranged above each rotating device; the problems that manual nailing of the stainless steel push-and-pull door frame pocket is low in work efficiency, large in labor intensity and dangerous, and nailing is not conveniently carried out on the higher or lower position are solved, the function of fully-mechanized compressing and nailing of the stainless steel push-and-pull door frame pocket is achieved, and the beneficial effects of being high in work efficiency, small in labor intensity, capable of achieving purely-mechanical nailing work, capable of carrying out automatic nailing work on the all angular positions of the door frame pocket and the like are achieved.
