Embodiment 1

[0025] like figure 1 As shown, the present invention is a formwork reinforcement structure at the horizontal construction joints of an underground pipe gallery, which includes a plurality of first pairs of pulling screws 1, a plurality of second pairs of pulling screws 2, a plurality of square logs 4, a template 5, a base plate 6 and a steel pipe 7; The bottom plate 6 is provided with a raised guide wall 8, and the top of the guide wall 8 is a construction joint; the first pair of pull screws 1 are arranged at the upper part of the guide wall 8 at equal distances horizontally; both sides of the top of the guide wall 8 The edges are respectively pasted with double-sided tape; the lower part of the template 5 is vertically arranged on the outside of the two double-sided tapes; the square wood 4 is vertically equidistantly arranged on the outside of the two templates 5; the second pair of pulling screws 2 are arranged on the two templates 5 from bottom to top in several rows, the...

Embodiment 2

[0029] A construction method for the formwork reinforcement structure at the horizontal construction joints of the underground pipe gallery described in Embodiment 1, comprising the following steps:

[0030] (1) First, pour the concrete of the bottom plate and the guide wall according to the design drawings, and set the first pair of tension screws at the set position of the guide wall at the same distance horizontally before pouring;

[0031] (2) After the concrete of the bottom plate and the guide wall is poured, the first pair of pulling screws at the guide wall are reserved. The top of the guide wall is the position of the horizontal construction joint of the pipe gallery, and the double-sided tape is pasted on the edges of both sides of the top of the guide wall. , and then set the template on the outside of the two double-sided tapes;

[0032] (3) Arrange several rows of second pairs of pull screws on the two templates from bottom to top. When setting, ensure that the se...

Abstract

The invention discloses a formwork reinforcing structure at the underground pipe gallery horizontal construction joint and a construction method, belongs to the technical field of building construction, and relates to urban underground comprehensive pipe gallery construction. The structure comprises a plurality of first counter-pull screws, a plurality of second counter-pull screws, a plurality ofsquare woods, a formwork, a bottom plate and steel pipes. Through optimization of materials and improvement of the construction method, the formwork reinforcing structure and the construction methodare utilized, so that the impression quality at the underground pipe gallery horizontal construction joint can be effectively improved, furthermore, the occurrence of quality problems such as dislocation, slurry leakage and the like at the horizontal construction joint can be effectively avoided, meanwhile, the construction material is common, the construction cost can be effectively reduced, andthe practicability is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, relates to the construction of an urban underground comprehensive pipe gallery, and in particular relates to a formwork reinforcement structure at a horizontal construction joint of an underground pipe gallery and a construction method. Background technique [0002] With the popularization of urban underground comprehensive pipe gallery construction, more and more construction units pay attention to the visual quality of underground comprehensive pipe gallery construction; common quality problems such as misplacement of horizontal construction joints and slurry leakage often occur in urban underground pipe gallery construction. , which seriously affects the look and feel quality of the underground pipe gallery; therefore, a formwork structure and reinforcement method for the horizontal construction joints of the underground pipe gallery are urgently needed. SUMMARY OF THE INVENTION...
