Embodiment Construction

[0041] Contraction below Figure 1-5 The present invention will be further described in further detail.

[0042] The present application discloses a positioning frame for a sliding support pad. Refer figure 1 and figure 2 The positioning frame for the sliding support is provided with a fixing device 1, and the fixing device 1 includes a base 11 and a fixing mechanism 12 disposed on the base 11. The fixing mechanism 12 includes four support stud 121 in the base 11, four support studs 121 are parallel to each other and are mounted on the base 11 through the bearing, and thus each support stud 121 can rotate on the base 11. . The threaded holes are drilled in front of the cast template 3 and the support stud 121 is fitted to the threaded bore, thereby mounting the base 11 on the pouring template 3. A tensile device 2 is provided on the base 11, and the tensile device 2 includes a support 21 disposed on the base 11 and a clamping mechanism 22 and a stretting mechanism 23 disposed on th...

Abstract

The invention relates to a positioning frame for a sliding support base plate. The positioning frame for the sliding support base plate comprises a fixing device and a tensioning device, wherein the fixing device comprises a base and a fixing mechanism used for fixing the base to a pouring formwork; the tensioning device comprises a support arranged on the base and a clamping mechanism arranged on the support; the clamping mechanism comprises two oppositely-arranged clamping plates and a locking assembly used for controlling the two clamping plates to clamp a base plate; and the tensioning device further comprises a force applying mechanism for applying a pulling force to the base plate through the two clamping plates. The positioning frame can effectively ensure the levelness and the smoothness of the base plate, so that the construction quality of the base plate is ensured. The invention further relates to a construction method of a sliding support stair. The construction method comprises the steps of building the pouring formwork, erecting the positioning frame, pouring and removing the formwork; and the positioning frame tensions the base plate, so that the flatness of the base plate is guaranteed, and the construction quality of the base plate and the sliding support stair can be effectively guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of stair construction equipment, and more particularly to a construction method of a positioning frame and a sliding support stair, a sliding support staircase. Background technique [0002] Currently, for the stairs of the building, the common style is a plate staircase, but the stairs of the stairs are poorly seismic, and the safety is low in the earthquake, which seriously affects the escape function of the building during the earthquake. As an alternative to the plate staircase, the sliding seat staircase is replaced due to its good seismic, and is widely used in buildings with higher seismic performance requirements. [0003] Sliding support stairs are named after the opening of the platform beam at the lower end of the ladder plate. The material of the sliding support is usually selected from the steel plate or polytetrafluoroide to ensure effective sliding between stairs and platforms. In general, ...
