Description

Superimposed sheet hoisting point reinforcing apparatus

Technical Field

The application relates to a superimposed sheet technical field specifically is a superimposed sheet hoisting point reinforcing apparatus.

Background

The laminated slab is an assembled integral floor slab formed by laminating prefabricated slabs and cast-in-place reinforced concrete layers. The laminated slab has good integrity, the upper surface and the lower surface of the slab are smooth, the decoration of a finish coat is convenient, and the laminated slab is suitable for high-rise buildings and large-bay buildings with higher requirements on the integral rigidity.

Fig. 1 is a perspective view of a conventional composite slab (cast-in-place reinforced concrete layer is not shown in the drawing), and in order to facilitate a hoisting operation by a hoisting device, a hoisting point (as shown in fig. 2 to 3) is usually required to be provided on the composite slab. Before the precast slab 100 is poured, the transverse ribs 200 need to be laid on the mold at intervals, and then the longitudinal ribs 300 need to be laid on the transverse ribs 200 at intervals (as shown in fig. 4-5), so that the shorter (i.e., the smaller span) transverse ribs 200 can support the longer (i.e., the larger span) longitudinal ribs 300, thereby being beneficial to improving the strength of the precast slab 100; the wavy connecting ribs 500 are welded on the two adjacent longitudinal ribs 300 at the positions where the lifting points need to be formed, the upper parts of the connecting ribs 500 are welded on the reinforcing ribs 400 which are longitudinally arranged, and the connecting positions between the reinforcing ribs 400 and the two connecting ribs 500 form a lifting point, so that the hook 600 on the lifting device can be conveniently lifted (as shown in fig. 3); and after the prefabricated slab 100 is hoisted in place, a reinforced concrete layer is poured above the prefabricated slab.

However, the above construction method still has the following defects: (1) Before the precast slab 100 is poured, since the weight of the longitudinal bars 300, the connecting bars 500, and the reinforcing bars 400 is mainly applied to the transverse bars 200, it is necessary to place a spacer below the transverse bars 200 to support the transverse bars 200, thereby preventing the transverse bars 200 from being excessively deformed; (2) When the transverse ribs 200 are laid below the longitudinal ribs 300, although the strength of the prefabricated panel 100 can be improved, during the hoisting operation, the acting force of the hooks 600 on the hoisting points mainly acts between the connecting ribs 500 and the prefabricated panel 100 and between the two longitudinal ribs 300 and the prefabricated panel 100, and the transverse ribs 200 hardly act, so that the strength of the hoisting points is not enough, cracking is easy to occur, and potential safety hazards exist.

Referring to fig. 6 to 15, an embodiment of the present application provides a superimposed slab hanging point reinforcing apparatus, including a reinforcing rib 1 and two longitudinal ribs 2, wherein the reinforcing rib 1 is disposed above the two longitudinal ribs 2 along a longitudinal direction. The superimposed sheet hoisting point reinforcing device further comprises two connecting ribs 3, each connecting rib 3 comprises a connecting section 31 and a hoisting section 32 of an inverted V-shaped structure, and the connecting sections 31 and the hoisting sections 32 are alternately connected; the upper portion of hoist and mount section 32 sets up in reinforcing muscle 1, and two lower parts of hoist and mount section 32 set up in the muscle 2 that indulges that corresponds, and indulge and be formed with the clearance that is used for at least one horizontal muscle 4 to pass between muscle 2 and linkage segment 31.

According to the composite slab hoisting point reinforcing device, the connecting sections 31 and the hoisting sections 32 are alternately connected, and the upper parts of the hoisting sections 32 are arranged on the reinforcing ribs 1, so that hoisting points (as shown in fig. 6 and 11) can be formed at the connecting positions between the reinforcing ribs 1 and the two hoisting sections 32, and the hoisting operation of the hoisting device is facilitated. Because the two lower parts of the hoisting section 32 are arranged on the corresponding longitudinal bars 2, and a gap for at least one transverse bar 4 to pass through is formed between each longitudinal bar 2 and each connecting section 31, which is equivalent to that the connecting section 31 is added on each connecting bar 3 while the position relation between each transverse bar 4 and each longitudinal bar 2 is not changed, and the connecting section 31 is supported below the transverse bar 4 (as shown in fig. 7, 8, 12 and 13), the transverse bar 4 can be supported by the connecting sections 31 before the precast slabs are poured, so that cushion blocks do not need to be arranged below the transverse bars 4; during hoisting operation, a part of the acting force of the hook on the hoisting point is distributed between the transverse rib 4 and the precast slab, so that the effect of reinforcing the hoisting point is achieved, cracking during hoisting operation can be prevented, and the safety of the laminated slab is improved.

The specific structure of the connecting segment 31 is not limited in the present application, and reference is made to only two specific structures provided below, which are described in detail in the following first embodiment and second embodiment.

The first embodiment is as follows: as shown in fig. 6, 7 and 8, the connecting segment 31 has an arc-shaped structure. The connecting section 31 with the arc-shaped structure can be just matched with one transverse rib 4 to pass through, and the structure is simple and the processing is convenient.

The second embodiment: as shown in fig. 11, 12 and 13, the connecting segment 31 has a line-shaped structure. The connecting section 31 with the straight-line-shaped structure can be matched with at least one transverse rib 4 to penetrate through, and the connecting structure is simple and convenient to process. In addition, compared with the connecting section 31 with an arc structure, under the condition of the same longitudinal length, the I-shaped connecting section 31 equivalently reduces the number of hoisting sections 32, so that on one hand, the welding times between the hoisting sections 32 and the reinforcing ribs 1 and between the hoisting sections 32 and the longitudinal ribs 2 can be reduced, and the processing is more convenient; on the other hand, the total length of the connecting rib 3 is favorably shortened, and the material cost is saved.

Referring to fig. 15, in the second embodiment, at least one bent portion 311 is formed by bending the connecting segment 31 upward at intervals, the upper portion of the bent portion 311 is provided on the reinforcing rib 1, and the lower portion of the bent portion 311 is provided on the corresponding longitudinal rib 2. When the length of the connecting section 31 of the "in-line" structure is long, at least one bent portion 311 may be formed by bending the connecting section 31 upward at intervals, so that the connection strength between the connecting section 31 and the reinforcing rib 1 is enhanced by the bent portion 311.

Referring to fig. 15, in the second embodiment, the bending portion 311 has an arc structure, an isosceles trapezoid structure, or a rectangular structure. The bending portions 311 of the arc-shaped structure or the isosceles trapezoid structure or the rectangular structure are more uniform and symmetrical, so that the stress uniformity can be improved.

Referring to fig. 9, 10, 14 and 15, in some embodiments of the present application, when the hanging section 32 is located outside the connecting bar 3, a supporting section 321 for supporting the transverse bar 4 extends from an end of the hanging section 32 away from the connecting section 31. When the connecting section 31 is positioned at the outer side of the connecting rib 3, the connecting section 31 can still support the transverse rib 4; when the hoisting section 32 is located at the outer side of the connecting rib 3 and the corresponding position needs to be provided with the transverse rib 4, one end of the hoisting section 32 deviating from the connecting section 31 cannot support the transverse rib 4, but under the action of the supporting section 321, the defect can be overcome just.

Referring to fig. 10 and 15, in some embodiments of the present application, the support section 321 is an arc-shaped structure or a "straight" structure. The support section 321 with the arc structure or the I-shaped structure can effectively support the transverse rib 4, and has simple structure and convenient processing.
