Description

Technical Field

[0001] This utility model relates to the field of prefabricated building component technology, specifically an enhanced reinforced concrete composite slab. Background Technology

[0002] Prefabricated buildings, as a form of construction conforming to industrialized production methods, have advantages such as fast construction speed, convenient construction, low emissions, and easy control of product quality. They can promote the healthy development of my country's construction industry and achieve predetermined energy conservation and emission reduction goals. Precast reinforced concrete composite slabs are the most widely used precast components in prefabricated buildings. As part of a composite structure, reinforced concrete composite slabs are a structural form that combines precasting and cast-in-place methods. During the construction process, a precast base slab is first placed at the bottom, which acts as a formwork when the upper layer of concrete is poured. Then, the two parts of concrete form a whole to bear the load.

[0003] The prior art includes a precast reinforced concrete composite slab with application number 201920967805.1. The precast reinforced concrete composite slab includes a prestressed concrete composite slab, high-strength prestressed steel wires, and transverse perforated steel bars. The high-strength prestressed steel wires are longitudinally embedded in the prestressed concrete composite slab, and the transverse perforated steel bars are transversely inserted through the protruding ribs of the prestressed concrete composite slab. The composite slab is assembled by using a male slab and a female slab, which makes the assembly more compact and reliable. Moreover, the transverse perforated steel bars connect multiple sets of male and female slabs with the protruding rib structures on them to form a continuous whole, which is not easy to loosen and is convenient and time-saving to assemble. However, the 90-degree connection between the transverse and longitudinal steel bars is usually achieved by binding with steel bars, which results in poor accuracy and stability of the 90-degree connection. Utility Model Content

[0004] The purpose of this utility model is to provide an enhanced reinforced concrete composite slab to solve the problem that in the prior art, the 90-degree connection of transverse and longitudinal steel bars is usually achieved by binding steel bars, which results in poor accuracy and stability of the 90-degree connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an enhanced reinforced concrete composite slab, comprising a concrete composite slab body, wherein the concrete composite slab body is filled with transverse and longitudinal reinforcing bars, wherein the transverse and longitudinal reinforcing bars are provided with a right-angle positioning mechanism, and the right-angle positioning mechanism includes a lower positioning seat, wherein an upper positioning seat is provided on the upper side of the lower positioning seat by bolts, and the lower positioning seat and the upper positioning seat are engaged at the 90-degree intersection of the transverse and longitudinal reinforcing bars, and a pouring thickness adjustment mechanism is also provided on one side of the lower positioning seat and the upper positioning seat.

[0006] Furthermore, both the lower positioning seat and the upper positioning seat are circular metal supports, and the outer diameters of the lower positioning seat and the upper positioning seat are the same.

[0007] Furthermore, a first locking groove is provided on one side of the lower positioning seat, and a second locking groove is provided on one side of the upper positioning seat.

[0008] Furthermore, the bolt includes a fixing screw that is vertically welded to one side of the lower positioning seat, and one end of the fixing screw passes through the upper positioning seat and is fixed by a limiting nut.

[0009] Furthermore, the right-angle positioning mechanism is alternately installed at the right-angle intersections of the transverse and longitudinal reinforcing bars, and is secured with steel wire at intersections where no right-angle positioning mechanism is installed.

[0010] Furthermore, the pouring thickness adjustment mechanism includes an upper adjustment seat and a lower adjustment seat. The upper adjustment seat has a first height adjustment bolt threaded on one side, and the lower adjustment seat has a second height adjustment bolt threaded inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model provides right-angle positioning mechanisms inside the transverse and longitudinal reinforcing bars. The right-angle positioning mechanism includes a lower positioning seat and an upper positioning seat. By fixing the lower positioning seat and the upper positioning seat to the outside of the 90-degree intersection of the transverse and longitudinal reinforcing bars with bolts, it is easy to improve the accuracy and stability of the 90-degree connection between the transverse and longitudinal reinforcing bars. At the same time, it increases the structural strength inside the concrete composite slab and improves the compressive performance. Moreover, the setting of multiple right-angle positioning mechanisms to pre-fix the reinforcing bars is beneficial to improving the accuracy of subsequent reinforcing bar binding.

[0013] 2. This utility model also includes a pouring thickness adjustment mechanism on one side of the lower positioning seat and the upper positioning seat. The pouring thickness adjustment mechanism includes an upper adjustment seat and a lower adjustment seat. A first height adjustment bolt is threaded on one side of the upper adjustment seat, and a second height adjustment bolt is threaded inside the lower adjustment seat. The thickness of the poured concrete layer is maintained at the distance between the ends of the two height adjustment bolts. By rotating the height adjustment bolts, the extension length of the height adjustment bolts can be adjusted, thereby adjusting the pouring thickness of the concrete on both sides of the right-angle positioning mechanism. Moreover, the use of multiple single-layer height adjustment bolts can provide stable parallel support for the lower part of the steel reinforcement layer composed of transverse and longitudinal steel reinforcement, so that the steel reinforcement layer is always kept in the middle of the concrete composite slab.

The concrete composite slab body 1 is filled with transverse reinforcing bars 2 and longitudinal reinforcing bars 3. The transverse reinforcing bars 2 and longitudinal reinforcing bars 3 are provided with right-angle positioning mechanisms. The right-angle positioning mechanisms include a lower positioning seat 5 and an upper positioning seat 6 is provided on the upper side of the lower positioning seat 5 by bolts. The lower positioning seat 5 and the upper positioning seat 6 are engaged at the 90-degree intersection of the transverse reinforcing bars 2 and the longitudinal reinforcing bars 3. The bolts include a fixing screw 7 vertically welded to one side of the lower positioning seat 5. One end of the fixing screw 7 passes through the upper positioning seat 6 and is connected and fixed by a limiting nut 8. The right-angle positioning mechanisms are alternately arranged at the right-angle intersection of the transverse reinforcing bars 2 and the longitudinal reinforcing bars 3. At the intersections where no right-angle positioning mechanisms are provided, the steel wire is used for binding. By fixing the lower positioning seat 5 and the upper positioning seat 6 to the outside of the 90-degree intersection of the transverse reinforcing bars 2 and the longitudinal reinforcing bars 3 by bolts, the accuracy and stability of the 90-degree connection of the transverse reinforcing bars 2 and the longitudinal reinforcing bars 3 are improved.

A first height adjustment bolt 4 is threaded on one side of the upper adjustment seat 11, and a second height adjustment bolt 12 is threaded inside the lower adjustment seat 13. By rotating the height adjustment bolt, the extension length of the height adjustment bolt can be adjusted, thereby adjusting the pouring thickness of the concrete on both sides of the right-angle positioning mechanism. Moreover, the use of multiple single-layer height adjustment bolts can provide stable parallel support for the lower part of the steel reinforcement layer composed of transverse steel reinforcement 2 and longitudinal steel reinforcement 3, so that the steel reinforcement layer is always kept in the middle of the concrete composite slab 1.

[0023] The working principle and usage process of this utility model are as follows: In use, the interior of the concrete composite slab 1 is filled with transverse steel bars 2 and longitudinal steel bars 3, and a right-angle positioning mechanism is provided inside the transverse steel bars 2 and longitudinal steel bars 3.
