Problems solved by technology

This construction method has the following disadvantages: 1. The formwork is easily damaged during the demolition process, and the material cannot be used repeatedly, and it takes time and effort to make it again; 2. The anchor bolt holes of the support are easy to shift, and the lining is PVC pipe Affect the bonding effect of the support mortar; 3. The concrete pouring process is easy to deform and displace the formwork, and the shape accuracy and appearance quality of the pad stone are poor; 4. There are deviations in the processing quality of the wooden formwork, which is prone to problems such as grout leakage and pockmarks, which affect the plinth stone 5. The reserved holes for support installation are easy to shift, which makes the support unable to be installed

Embodiment 1

[0021] Such as figure 1 As shown, in this embodiment, a pad stone setting mold includes a limiting structure and several templates 1 arranged on the limiting structure and used to surround and form a concrete pouring space. The limiting frame 21 with the same cross-sectional profile, the template 1 is a steel template.

[0022] Using the limit structure as the positioning and installation reference of the formwork 1, the formwork 1 is installed on the limit structure, the formwork 1 surrounds and forms a space for pouring concrete, and the work of pouring concrete is performed after the reinforcement cage is installed. After the concrete is formed, the template 1 and the limiting structure are removed. In this scheme, due to the use of steel formwork, when pouring concrete, the steel formwork can resist the impact of concrete and avoid deformation, which is conducive to ensuring the shape accuracy of formwork 1 itself. Compared with wood formwork, the strength and surface qua...

Embodiment 2

[0025] Such as figure 1 , figure 2 As shown, on the basis of the above embodiments, in this embodiment, the position-limiting structure includes several steel pipe mounting brackets 22 arranged in the position-limiting frame 21, and the steel pipe mounting brackets 22 are installed with The steel pipe 23 of reserved hole.

[0026] The steel pipe 23 can extend into the space formed by the template 1. When pouring concrete, since the steel pipe 23 occupies part of the space, after the concrete is formed, the steel pipe 23 can be taken out to form a reserved hole.

[0027] Utilizing the steel pipe installation bracket 22 as the basis for installing the steel pipe 23 can control the position of the steel pipe 23 to maintain the position required by the design, can save the steps of positioning and installing the steel pipe, and is conducive to improving construction efficiency, and multiple constructions can ensure that the steel pipe The position is always consistent, ensuring...

Embodiment 3

[0036] On the basis of the above embodiments, in this embodiment, the template 1 and the limiting frame 21 are connected by bolts. This is beneficial to facilitate construction. After the pad stone is formed, the formwork 1 and the limiting structure are easily removed by loosening the bolts, so as to avoid deformation of the formwork 1 and the limiting frame during the demoulding process.

Abstract

The invention discloses a cushion stone shaping mold. The mold comprises a limit structure and a plurality of templates arranged on the limit structure and used to form a concrete pouring space by surrounding, wherein the limit structure comprises a limit frame with the same cross-sectional profile as the cushion stone, and the templates are steel templates. The cushion stone shaping mold has thebeneficial effects that the solution uses the limit structure as an installation reference of the templates, so that the shape accuracy of the templates can always be kept stable under the condition that the shape accuracy of the limit structure remains stable, and the construction quality of the cushion stone is kept stable in the case of multiple constructions. The steel templates used in the scheme have the advantage of high structural strength, can resist deformation under the impact of concrete, avoid the surface in contact with the concrete from being worn and forming a pitted surface, and can be repeatedly used to ensure the forming quality of the cushion stone.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a plinth shaping die. Background technique [0002] In bridge engineering, the pad stone is the installation platform of the bridge bearing, which transmits the load of the upper part of the bridge downward. The quality of its construction directly affects the installation quality of the bridge support and the durability of the bridge. For example, the flatness, slope, and bolt reservation of the pad stone directly affect the installation and positioning of the support. The quality of the pouring and maintenance of the pad stone It directly affects its strength and durability, and then affects the durability of the main body of the bridge and the maintenance cost during the later use of the bridge. [0003] At present, in most bridge constructions, wooden formwork assembled on site is used for the construction of pad stones. This construction method has the followin...
