Problems solved by technology

In order to keep the bladder in a cylindrical shape before inflating, it must have sufficient rigidity. Using soft materials to make the bladder requires a larger amount of material, which is not convenient for transportation and installation, and the economy is not ideal
When the fiber material is used to make the capsule, the airtightness is poor, and it is difficult to ensure the airtightness of the air nozzle, the capsule and the inflatable carcass made of inner polymer thermoplastic plastic when the inflation nozzle is installed on the capsule
The most important structure of the inflatable structure is the joint. The invention does not provide the manufacturing method of the capsule, nor does it provide the structure and manufacturing method of its end, which reduces the practicability of the invention

Embodiment 1

[0034] Embodiment 1: refer to figure 1 , Figure 1-2 , Figure 1-2 , Figure 4-3 The specific implementation method includes an inner bag 3, the inner bag 3 can be made of plastic film, rubber, etc., with openings at both ends as material, and the inner bag 3 is opened on the bag wall at the required position of the inner bag and adopts heat sealing or gluing Method Install the inflation port 4, heat-seal or glue the two ends of the inner bag 3 barrel material at the sealing line 5 to make a gas-barrier inner bag 3, and put the inner bag 3 with the inflation port 4 into the knitting machine , Disposable weaving into the integrity of the outer bag 2 containing the inner bag 3, on the outer bag 2 in an appropriate place to open the inflation port 4 exposed. The material of the outer bag 2 can be high-strength fiber materials such as plastic fibers and glass fibers. Install and fix the manufactured barrel bag at the specified position, and fill in the compressed air or other ...

Embodiment 2

[0035] Embodiment 2: refer to figure 2 , Figure 2-1 to Figure 2-3 The specific embodiment includes an outer bag 2 and an inner bag 3, the outer bag 2 and the inner bag 3 are made of double-layer nested tube materials with openings at both ends, and the inner layer tube material and the outer layer tube material can be bonded or partially glued Together, can also be completely separated. The inner shell material can be made of plastic film, rubber and other materials, and the outer shell material can be made of plastic fiber, glass fiber, non-woven fabric and other materials. After opening the inner and outer layers of the barrel material on the bag wall at the required position, install the inflation port 4 on the bag wall of the inner bag 3 barrel material by heat sealing or gluing, and seal the two ends of the inner bag 3 barrel material at the sealing line 5. Heat-sealing or gluing to make a gas-barrier inner bag 3, folding and binding the tube material of the inner bag...

Embodiment 3

[0036] Embodiment 3: with reference to Fig. 3, Figure 3-1 to Figure 3-3 The specific embodiment includes the inner bag 3, and the inner bag 3 can be made of plastic fiber, glass fiber, non-woven fabric and other materials. The two ends of the barrel material of the inner bag 3 are made into the inner bag 3 by any one or more methods such as fusion, gluing or sewing at the suture line 5, and the inner bag 3 is made of two pieces of plastic film, rubber and other materials. The outer bag 2 is made by means of fusion, gluing, etc., and the outer bag 2 should have an overlapping edge 6 with air-blocking ability around the periphery of the sheet. Appropriate places are opened on the bag wall of the outer bag 2 and the inflation port 4 is installed by heat sealing or gluing. Install and fix the manufactured barrel bag at the specified position, and fill in the compressed air or other gas with the specified pressure before pouring the concrete, that is, the tubular inflatable filli...

Abstract

The invention discloses a tubular inflating filling mold for cast-in-situ concrete, which comprises a tube bag, wherein the tube bag consists of an outer bag and an inner bag, the outer bag consists of an equal section dimension cylindrical tube body and a variable section dimension tube end after the outer bag inflation and the inner bag consists of an equal section dimension cylindrical tube body and a variable section dimension tube end formed after the inner bag inflation, or the tube bag only consists of an airtight outer bag. The filling mold does not need to be inflated in the production and transportation stage, the size is small, the production and storage occupation space is small, the transportation cost is low, and the defects of requirement of a large production and storage space and high transportation cost of the existing tube and pipe production are overcome.

Description

technical field [0001] The invention relates to the technical field of building structure construction, in particular to a tubular air-filled mold for cast-in-place concrete. Background technique [0002] The cast-in-place reinforced concrete floor is the most important and widely used floor structure in construction engineering, and it is also the part with the largest amount of work in construction engineering. Structural floor systems in modern construction engineering mainly include beam-slab structure, beamless-slab structure and ribbed floor system. The traditional structure has the shortcomings of small economic span, small load bearing, heavy structure, and waste of materials. It is an effective way to overcome the above-mentioned shortcomings by filling the concrete floor with light materials and making a cast-in-place hollow floor with a light-weight filling mold inside. Cast-in-situ hollow-core slabs can be widely used in industrial, public buildings, and baseme...
