Embodiment 1

[0087] (1) manufacture female mold, as shown in Figure 1, 7 is female mold;

[0088] (2) According to sulfoaluminate cement: sand: early strength agent and 107 glue: the weight ratio of glass fiber and organic fiber is the ratio of 100: 200: 6: 5 to prepare each component material, add appropriate amount of water to mix the above materials Stir and mix evenly to prepare high-strength mixture slurry.

[0089] (3) Use a mortar pump to spray the aforementioned prepared slurry on the concave part of the box female mold (the concave part can be provided with an isolation film so as to facilitate demoulding), compact and smooth it, as shown in Figure 1, 7 represents the female mold. Die, 8 represents slurry.

[0090] (4) After curing and demoulding, the finished thin-walled box of the present invention is obtained.

Embodiment 2

[0092] (1) manufacture male mold, as shown in Figure 2, 9 is male mold;

[0093] (2) According to Portland cement: sand: water reducer and 107 glue: carbon fiber and organic fiber weight ratio of 100:120:4:6, prepare each component material, add appropriate amount of water to stir and mix the above materials Uniformly prepared high-strength mixture slurry.

[0094] (3) Spray the above-mentioned obtained slurry on the protruding part of the male mold 9 by manual smearing or with a cutting jet machine, compact and smooth it, as shown in Figure 2, 10 is the slurry, and 9 is the male mold.

[0095] (4) After curing and demoulding, the finished thin-walled box of the present invention is obtained.

Embodiment 3

[0097] (1) Manufacture core mold, as shown in Figure 6, 11 is core mold;

[0098] (2) Prepare each component material according to the weight ratio of Portland cement: sand: retarder: organic fiber is 100:180:6:8, add appropriate amount of water to stir and mix the above materials to obtain a high-strength mixture Material slurry.

[0099] (3) Apply a layer of demoulding release agent on the core mold 11, spray the aforementioned prepared slurry on the core mold with a mortar pump, compact and smooth it, as shown in Figure 6, 11 represents the core mold, 12 represents slurry.

[0100] (4) After curing and demoulding, the finished thin-walled box of the present invention is obtained.

[0101] The fiber-reinforced thin-walled box for reinforced concrete filling provided by the invention has the advantages of high strength, excellent deformation resistance and vibration resistance, and can meet various requirements for filling and evacuating concrete, and the manufacturing meth...

Abstract

Disclosed is a concrete-stuffing thin-wall case comprising a lower casing wall and four side casing walls, wherein the lower casing wall and the four side casing walls form an integral open basin, characterized in the prefabricated reinforcing rib crosses a sealing compound. The advantages of the invention are include high strength, good deformation resistance, fine vibration resisting performance, convenient construction work and low cost.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of November 29, 1999, the application number of 99115665.X, and the title of "fiber-reinforced thin-walled pipe (box) for reinforced concrete filling and its manufacturing method". (1) Technical field [0002] The invention relates to a filling member for reinforced concrete. In particular it relates to the improvement of thin-walled boxes for filling. (2) Background technology [0003] Reinforced concrete hollow slabs, especially cast-in-place reinforced concrete hollow slabs, are mostly filled with thin-walled boxes, which has the advantage of convenient construction and transportation. But because most of its tube wall is a single material (such as paper tube), there are insufficient strength, poor deformation resistance, and poor resistance to vibration damage. Therefore, it is urgent to develop a new thin-walled box. (3) Contents of the invention [0004] The...
