Embodiment 1

[0041] Such as Figure 1~4 shown.

[0042] A spherical filling body for a reinforced concrete hollow member, which is composed of a hollow ball 1 for producing a hollow structure in the reinforced concrete and a fixing clip 2 for clamping and connecting with the steel bars in the reinforced concrete so as to position the hollow ball, Such as image 3 shown. The hollow ball 1 is a spherical thin-walled hollow body made of hard plastic with certain strength and bearing capacity. The top and bottom of the hollow ball 1 are provided with two grooves 3, and the two grooves 3 can Parallel arrangement can also be arranged according to the specific direction of the steel mesh, wherein the parallel arrangement is the best, and one side or both sides of the groove 3 are provided with holes 4 for the insertion of the inverted cone 5 protruding from the bottom of the fixed card 2, such as figure 1 (a), in order to increase the fixation strength, figure 1 A structure in which holes are...

Embodiment 2

[0046] A method for fixing spherical fillers for reinforced concrete hollow members, comprising the following steps:

[0047] First, press the hollow ball of the present invention with the steel bar in one direction of the bottom layer, so that the steel bar is stuck into the groove at the bottom of the hollow ball, so that a row of hollow balls is "stringed" on the steel bar. In this process, pay attention to the spacing of the steel bar grid Control the position of the hollow ball;

[0048] Secondly, install the bottom fixing card so that the fixing card and the bottom of the hollow ball are integrated as a whole, fine-tune the position of the hollow ball, and embed the steel bar in the other direction (perpendicular to the direction of the groove) of the bottom floor into the fixing card, thus forming an orthogonal two-way at the bottom of the floor. The reinforcement grid, and the spherical filling body is fixed to the reinforcement node;

[0049] The third step is to pre...

Abstract

The invention relates to a spherical filling body for a reinforced concrete hollow component and a fixation method. The spherical filling body is characterized by consisting of a hollow sphere (1) forming a hollow structure in the reinforced concrete and a fixing clip (2) which is connected with reinforcing steel bars in the reinforced concrete in a clamping manner to locate the hollow sphere, wherein the hollow sphere (1) is a spherical thin wall hollow body which has a certain strength and bearing capacity and is made of hard plastics; two grooves (3) are respectively formed in the top and the bottom of the hollow sphere (1); holes (4) in which back tapers (5) protruding at the bottom of the fixing clip (2) are inserted are formed in one or two sides of the grooves (3); the fixing clip (2) consists of a clip body (201) and a back taper (5); a clip slot (202) for installing the reinforced steel bars in a clamping manner is formed in the center of the clip body (201); and the axial direction of the clip slot (202) is intersected with that of the grooves (3). The spherical filling body can be fixed reliably, and the construction efficiency and the quality are improved.

Description

technical field [0001] The invention relates to a building component, in particular to a filling body for manufacturing a hollow concrete component and a construction method thereof, in particular to a spherical filling body for a reinforced concrete hollow component and a fixing method. Background technique [0002] The emergence and application of reinforced concrete hollow floors began in the 1990s. In order to meet the needs of modern buildings with multiple functions, multi-purposes, large column nets, and large bays, the reinforced concrete floor structure has been continuously improved. With the continuous development and improvement of internal mold technology, the development of hollow floor (slab) is very rapid. It realizes the requirements of large column network and large space of buildings, and at the same time has good structural performance, which is suitable for various structural forms , especially multi-storey and high-rise buildings with large spans and la...
