Embodiment 1

[0040] Such as Figure 1-7 As shown, the steel skeleton of the base plate 1 is bound first, and then the base plate 1 is poured with formwork. The width of the base plate 1 is 1700mm and the height is 350mm. When pouring along the length of the base plate 1, expansion joints should be preset. Plate, welding stopper 7 at the intersection of asphalt wood wool board and steel mold, there are two stoppers 7 at one end of the asphalt wood wool board, distributed on both sides of the end of the asphalt wood wool board close to the steel mold, and the stoppers 7 are far away from telescopic Putty and fillet one side of the seam. Block 7 is wide and is 20mm.

[0041] The exposed size of the asphalt wood wool board is too small. In order to improve the overall aesthetic effect, the two stoppers 7 can not only clamp the asphalt wood wool board, locate the position and width of the expansion joint, but also increase the exposed size of the expansion joint.

[0042] After the bottom pla...

Embodiment 2

[0048] Such as figure 1 As shown, Gu'an East Station has four platforms and eight lines, platforms 2 and 3 are 12.5m wide, and both sides are concrete platform walls; platforms 1 and 4 are 9.5m wide, with concrete platform walls on one side and the front of the station on the other Unit has finished vertical retaining wall. There are two types of Gu’an East platform walls. The walls near the main line of platforms 2 and 3 have been constructed on site. The total height of the platform wall structure is 3m, and it is composed of a bottom plate, an axil, a wall, and an overhanging eave. See details figure 1

[0049] The platform wall is one of the most important structures of the entire platform. Its completion quality and effect play an important role in the effect of the entire platform, so we carefully plan the entire process before starting construction:

[0050] The platform wall formwork is made of steel molds, which have the following advantages: multiple turnovers can...

Embodiment 3

[0059] Between the concrete bar 8 and the mortar layer 10, an elastic pad 11, such as a rubber strip, is wrapped with a waterproof coiled material 12, and the elastic pad 11 is provided with vertical holes or voids along its axial direction. Cavity

[0060] The elastic pad 11 prevents the connection between the concrete bar and the mortar layer from being affected by thermal expansion and contraction, and they are squeezed to form cracks. The elastic pad 11 can play the role of a temperature joint. The elastic pad 11 is wrapped with a waterproof membrane 12. It can prevent the rainwater from soaking the elastic pad, making it aging and losing its elasticity. The holes or cavities of the elastic pad 11 can make it have greater deformation capacity and save more materials. The cavity is made of rubber spiral Ribs 13, rubber spiral ribs 13 and elastic pads can be integrally formed, and rubber spiral ribs 13 are horizontally arranged in holes or cavities, so that elastic pads 11 h...

Abstract

The invention relates to a construction method of a platform wall and the platform wall, and the construction method of the platform wall specifically comprises the following steps that S1, a platform wall concrete structure is divided into three sections, and the first section is divided into a bottom plate (1); the second section is divided into a haunching part (2); the third section is divided into an upper wall body (3); S2, a bottom plate (1) is constructed firstly; S3, construction is conducted on the haunched position (2); and S4, finally, an upper wall body (3) is constructed. The platform wall manufactured by the construction method comprises the bottom plate (1); the haunching part (2) on the bottom plate (1); and the upper wall body (3) arranged on the haunching part (2). According to the construction method, the precision of the installation formwork can be improved, and the size error of the platform wall manufactured according to the method is smaller.

Description

technical field [0001] The invention relates to a construction method of a platform wall, and also relates to a platform wall manufactured by the method. Background technique [0002] After the traditional platform surface layer is laid, the side cornice of the platform wall will expose the mortar adhesive layer. Generally, the side eaves and side eaves of the platform wall are plastered by hanging net plaster on the side, so that it can be temporarily decorated and beautified. The traditional treatment method will cause a lot of plaster peeling and discoloration, which not only affects the aesthetic effect, but also poses a risk to driving safety. [0003] Chinese Utility Model Patent Publication CN210049652U discloses the exterior wall structure of corrugated panes of cast-in-place prestressed fair-faced concrete elevated stations and the elevated station, specifically relating to a structure in which integrally cast-in-place prestressed clear-faced concrete is used for co...
