Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1, the conventional hollow floor slab includes a floor slab body 1 and a plurality of existing holes 2 disposed in the floor slab body 1, the existing holes 2 are arranged at intervals in a width direction of the floor slab body 1, and a length direction of each existing hole 2 is disposed along a length direction of the floor slab body 1. The traditional filling body for reinforcing the hollow floor slab comprises concrete filled in the existing hole 2, and the filling body has low strength and unobvious reinforcing effect on the hollow floor slab because no reinforcing steel bars are implanted in the concrete.
Combine shown in fig. 5, 6, the hollow floor filler reinforcing apparatus of this embodiment includes steel reinforcement cage body 3, steel reinforcement cage connecting rod 8, concrete filler 12 and connecting reinforcement 13.
Because existing hole 2 has certain length, if need better reinforcement effect, need set up as long as possible steel reinforcement cage body 3 in existing hole 2, but the problem that nevertheless will be as long as possible steel reinforcement cage body 3 carries to in the existing hole 2. It may be more conventional practice to provide a longitudinal through groove 14 with the same length on the upper end of the floor slab body 1 along the length direction of the existing hole 2, and directly place the reinforcement cage body 3 with the same length as the existing hole 2 into the existing hole 2 through the longitudinal through groove 14. However, this operation will result in an excessively long opening length of the longitudinal through groove 14 above the existing hole 2, which will damage the original structure of the floor slab body 1 too much and reduce the strength of the original structure. Consequently, this embodiment sets up steel reinforcement cage body 3 into multistage formula structure, or set up steel reinforcement cage body 3 into a plurality ofly, a plurality of steel reinforcement cage bodies 3 set gradually in existing hole 2 along the length direction of existing hole 2 of floor body 1, adopt the mode of concatenation extension, make the total length of a plurality of steel reinforcement cage bodies 3 reach the length of existing hole 2, and every steel reinforcement cage body 3's length is shorter, thereby only with set up length slightly be greater than the vertical logical groove 14 of the length of steel reinforcement cage body 3 above existing hole 2, the length of seting up of vertical logical groove 14 has been shortened, as few as possible original structure of floor body 1 has been destroyed.
The steel reinforcement cage bodies 3 in this embodiment are all in a circular tube shape. The structure of the steel pipe pile reinforcement cage can be similar to that of a steel pipe pile reinforcement cage in the existing building field, and the ring ribs 4 and the main ribs 5 are bound to form a pipe cage-shaped structure.
Because back in a plurality of steel reinforcement cage bodies 3 carried existing hole 2, under the limited condition of the 14 length in vertical logical groove, steel reinforcement cage body 3 is not the direction connection to can not connect as whole, thereby be unfavorable for improving the intensity of obturator. So every two steel reinforcement cage bodies 3 are connected through at least one steel reinforcement cage connecting rod 8 to make a plurality of steel reinforcement cage bodies 3 that are located existing hole 2 be connected as whole by steel reinforcement cage connecting rod 8, this whole skeleton that is the obturator.
Combine fig. 4, 5 to show, in order to promote the reinforcement effect, still inserted connecting reinforcement 13 in two adjacent existing holes 2 of width direction along floor body 1, connecting reinforcement 13 is U type reinforcing bar, during the in-service use, is the type of falling U, and its both ends insert the bottom of two existing holes 2 respectively. The bottom of existing hole 2 is inserted at the both ends of connecting reinforcement 13, realize the anchor of connecting reinforcement 13 on floor body 1, and simultaneously, connecting reinforcement 13 still is connected with the steel reinforcement cage body 3 in existing hole 2, thereby the anchor of steel reinforcement cage body 3 and floor body 1 has been realized, additionally, because the both ends of connecting reinforcement 13 insert in the existing hole 2 of two differences, thereby realize the connection of the steel reinforcement cage body 3 in the existing hole 2 of these two differences, if the superimposed connecting reinforcement 13 that sets up in the existing hole 2 on floor body 1, thereby can connect the steel reinforcement cage body 3 in all existing holes 2 as overall structure, can obviously promote floor body 1's intensity.
In addition, connecting reinforcement 13 can set up a plurality ofly along the length direction interval of existing hole 2, makes and sets up a plurality of steel reinforcement cage bodies 3 between per two connecting reinforcement 13, the anchor effect of promotion steel reinforcement cage body 3 that can be further and floor body 1.
As shown in fig. 6-8, the reinforcement cage body 3 of the present embodiment includes four ring bars 4, four main bars 5, two reinforcement cage center rings 6, and eight support bars 7.
Specifically, four annular ribs 4 are coaxially distributed at intervals along the axial direction. The four main ribs 5 are uniformly distributed along the circumferential direction of the ring ribs 4, and each main rib 5 is bound and fixed with the four ring ribs 4.
Four supporting ribs 7 are arranged on the two annular ribs 4 at the two ends in a binding manner along the circumferential direction, the length direction of each supporting rib 7 points to the center of the annular rib 4, the outer ends of the supporting ribs 7 are bound and fixed with the annular ribs 4, and the inner ends of the supporting ribs 7 are bound and fixed with the center ring 6 of the reinforcement cage, and of course, a welding and fixing manner can also be adopted. Namely, the centers of the two ring ribs 4 at the two ends of the steel reinforcement cage body 3 are provided with a steel reinforcement cage center ring 6, and the steel reinforcement cage center ring 6 is fixedly connected with the ring ribs 4 outside the steel reinforcement cage center ring 6 through the support ribs 7. The ring rib 4 and the steel reinforcement cage center ring 6 are both circular-ring-shaped steel reinforcements. The reinforcement cage body 3 is prefabricated in advance. The length of each reinforcement cage body 3 is less than 50cm, so that the reinforcement cage bodies can be conveniently placed into the longitudinal through grooves 14 one by one. Of course, the size of the longitudinal through grooves 14 also needs to be limited, and the length of the longitudinal through grooves 14 is greater than the length of one reinforcement cage body 3 and less than the lengths of two reinforcement cage bodies 3; the width of the longitudinal through groove 14 is larger than the diameter of the reinforcement cage body 3. So that the reinforcement cage body 3 can be placed one by one into the longitudinal through groove 14 and axially move in the existing hole 2.
In order to improve the construction efficiency, the connection of the plurality of reinforcement cage bodies 3 can be completed outside the existing holes 2, and then the connected reinforcement cage bodies 3 are placed into the existing holes 2 from the longitudinal through grooves 14.
