Problems solved by technology

However, in construction projects, there are often some phenomena due to poor beam width control, mold expansion, necking, and insufficient steel protection layer. The main problems are all on the beam side formwork. Relevant measures achieve the purpose of controlling the beam width, preventing beam side mold expansion, shrinkage, and irregular beam cross-sectional shapes, while ensuring low cost, convenient use, and saving construction time, which has become a major problem

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Cooperate with reference figure 2 Shown, be the flow chart of the present invention's prefabricated inner mortar PVC pipe used as the internal support construction method of the beam side form, comprising the following steps:

[0017] 1) Set up a support frame under the beam, and set up the bottom template of the beam;

[0018] 2) Set up the formwork on one side of the beam and fix it with steel bars;

[0019] 3) Cooperate with reference image 3 As shown, a PVC pipe 10 filled with mortar is supported on the inner wall of the side form as an inner support, and the side forms on both sides are tightened against the PVC pipe 10 filled with mortar through pull bolts or clamps to form a stable system . Among them, the inner keel of the template is 20, and the outer keel is 21;

[0020] 4) Set up the other side form of the beam and fix ...

Abstract

The invention discloses a construction method for prefabricating a mortar filled polyvinyl chloride (PVC) tube as an inner support for beam side dies. The construction method comprises the following steps of: 1) arranging a supporting frame below a beam, and arranging a bottom template of the beam; 2) arranging a side die of the beam, and binding a steel bar for fixing; 3) supporting the mortar filled PVC tube on the inner wall of the side die to form the inner support; 4) arranging another side die of the beam, and fixing the side die with the mortar filled PVC tube; and 5) arranging a keel, reinforcing the beam template, and finishing mounting. Due to the mortar filled PVC tube serving as the inner support of the beam side dies, phenomena of necking, expansion and the like of the beam template are avoided; the beam side dies can be jacked and are tensioned by split bolts and the like; during construction, the beam side dies are difficult to deform; and therefore, the globality and the stability of the beam template are improved.

Description

technical field [0001] The invention relates to a construction method for internal support of a beam side formwork, in particular to a construction method for using a prefabricated inner mortar PVC pipe as an internal support for a beam side formwork. Background technique [0002] During the construction process of construction projects, the quality of formwork production and installation plays an important role in ensuring the smooth appearance and accurate geometric dimensions of concrete and reinforced concrete structures and components, as well as the strength and rigidity of structures. Beam formwork is an important part of construction projects. Any construction project is inseparable from beam formwork. The correct use of beam formwork in construction projects can effectively improve the overall construction level of the building, thereby further ensuring people's life safety and quality of life. In order to ensure the quality of the project, the visual effect and the...
