Description

Technical Field

[0001] This utility model belongs to the field of building component technology, and in particular relates to a steel truss for a concrete wall steel reinforcement skeleton that can be assembled quickly. Background Technology

[0002] The existing concrete walls of buildings use a reinforced steel frame, which includes a steel truss, horizontal reinforcing bars, and a steel mesh. The steel truss is welded to the vertical reinforcing bars at intervals using steel mesh clips. The horizontal reinforcing bars are placed at the intersections of the steel mesh clips and the vertical reinforcing bars and then tied together with wire. While this can speed up the construction of the reinforced steel frame for the concrete wall to some extent, it also requires the horizontal reinforcing bars to be tied and fixed to the vertical reinforcing bars during the assembly process. Otherwise, the horizontal reinforcing bars are prone to displacement, affecting the stability of the concrete wall. The binding and processing of each intersection of vertical and horizontal reinforcing bars requires a significant amount of time and labor, impacting the project schedule. Utility Model Content

[0003] This invention provides a steel truss for quickly assembling a steel reinforcement cage for concrete walls, which can effectively solve the above-mentioned problems.

[0004] This utility model is implemented as follows:

[0005] A steel truss for rapid assembly of a concrete wall steel reinforcement skeleton includes steel mesh clips and vertical steel bars. The steel mesh clips are elongated and have slots at both ends. The inner side of each slot has a corresponding hook. The steel mesh clips are welded at intervals to two parallel vertical steel bars. The steel mesh clips have placement holes or placement grooves on their upper sides. The placement grooves or placement holes are located on the inner and / or outer sides of each vertical steel bar.

[0006] As a further improvement, the placement hole can be circular, elliptical, triangular, or square.

[0007] As a further improvement, the steel mesh buckle is provided with multiple placement holes of different diameters side by side.

[0008] As a further improvement, the placement hole is a right triangle, with the hypotenuse of the right triangle opposite to the vertical reinforcing bar and the right angle located on the upper side of the steel mesh buckle.

[0009] As a further improvement, the placement slot is semi-circular, semi-elliptical, "U"-shaped, or "V"-shaped.

[0010] As a further improvement, the inner side of the placement groove near the vertical reinforcing bar is flush with the vertical reinforcing bar.

[0011] As a further improvement, the bayonet opening has at least one pair of hooks on its inner side, and a limiting groove is provided on the outer side of the bayonet opening corresponding to the hooks, with a retaining ring sleeved in the limiting groove.

[0012] As a further improvement, the retaining ring is an elastic circular ring or an elliptical ring.

[0013] As a further improvement, the diameter of the elastic ring is 2 / 3 to 4 / 5 of the relative spacing between the limiting grooves.

[0014] As a further improvement, the major axis of the elastic elliptical ring is 3 / 4 to 4 / 5 of the relative spacing between the limiting grooves, or the minor axis is 1 / 3 to 3 / 5 of the relative spacing between the limiting grooves.

[0015] The beneficial effects of this utility model are as follows: By setting placement grooves or holes at the placement positions of horizontal reinforcing bars, this application enables the rapid installation of horizontal reinforcing bars in the corresponding positions, avoiding movement or falling of the horizontal reinforcing bars during subsequent binding and processing, which would be detrimental to binding and processing and even pose a danger; and only the horizontal reinforcing bars at both ends and several positions in the middle of the reinforcing bar cage need to be reinforced and bound with vertical reinforcing bars or steel mesh clips, so as to quickly complete the construction of the concrete wall reinforcing bar cage. Furthermore, the use of a combination of limiting grooves and elastic retaining rings ensures the clamping strength during use, making the widespread application of the product possible.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0030] Reference Figure 1-8 As shown, a steel truss for quick assembly of a concrete wall steel reinforcement skeleton includes a steel mesh clip 1 and vertical steel bars 2. The steel mesh clip 1 is elongated and has slots 11 at both ends. The slots 11 have opposing hooks 12 on their inner sides. The steel mesh clip 1 is welded at intervals to two parallel vertical steel bars 2. The steel mesh clip 1 has placement holes 13 or placement grooves 14 on its upper side. The placement grooves 14 or placement holes 13 are located on the inner and / or outer sides of each vertical steel bar 2.

[0031] This application utilizes a method of punching out structures such as slots 11, hooks 12, placement holes 13, placement grooves 14, and limiting grooves 15 into a long strip of iron or steel plate, enabling quick and convenient processing. Then, the vertical reinforcing bars 2 are welded to one side of the placement holes 13 or placement grooves 14, ensuring the vertical reinforcing bars 2 are as close as possible to the placement holes 13 or placement grooves 14, thus allowing the installed horizontal reinforcing bars 4 to fit snugly against the vertical reinforcing bars 2. At the junctions of the vertical reinforcing bars 2 and horizontal reinforcing bars 4 around the perimeter of the reinforcing bar skeleton, binding is performed. Binding is also performed at the middle positions as needed. Due to the limiting effect of the placement grooves 14 or placement holes 13, binding can be performed at intervals of one or more positions, thereby reducing the amount of binding work and increasing assembly speed. The limiting effect of the placement grooves 14 or placement holes 13 also prevents the horizontal reinforcing bars 4 from moving during processing, facilitating processing operations and preventing the horizontal reinforcing bars 4 from slipping and causing danger. Finally, the steel mesh mold 5 is installed, and the steel mesh mold 5 is connected to the hooks 12 of the steel mesh clips 1, forming a steel mesh skeleton for concrete pouring.

[0032] Alternatively, horizontal reinforcing bars 4 can be welded to vertical reinforcing bars 2 or steel mesh clips 1 to further reduce welding connection points and improve the overall structural stability of the reinforcing bar cage.

[0033] Furthermore, the placement hole 13 is circular, elliptical, triangular, or square.

[0034] Furthermore, the steel mesh buckle 1 is provided with multiple placement holes 13 of different diameters arranged side by side.

[0035] It can accommodate horizontal steel bars of different sizes, and has good stability.

[0036] Furthermore, the placement hole 13 is a right triangle, with the hypotenuse of the right triangle opposite to the vertical reinforcing bar 2 and the right angle located on the upper side of the steel mesh buckle 1.

[0037] On the one hand, the triangular structure is stable, and on the other hand, it can accommodate the insertion of horizontal steel bars 4 of different sizes. Furthermore, under the action of gravity, the horizontal steel bars 4 are inserted downward into the placement hole 13, resulting in better structural stability.

[0038] Furthermore, the placement groove 14 is semi-circular, semi-elliptical, "U"-shaped, or "V"-shaped.

[0039] The “V” shaped structure can accommodate the placement of horizontal steel bars of different sizes and has good placement stability.

[0040] Furthermore, the inner side of the placement groove 14 near the vertical reinforcing bar 2 is flush with the vertical reinforcing bar 2.

[0041] This can better ensure the fit between the horizontal reinforcing bar 4 and the vertical reinforcing bar 2, which is beneficial to the stability of the overall reinforcing bar cage.

[0042] Furthermore, the bayonet 11 has at least one pair of hooks 12 on its inner side, and a limiting groove 15 is provided on the outer side of the bayonet 11 corresponding to the hooks 12, and a retaining ring 3 is sleeved in the limiting groove 15.

[0043] Multiple hooks 12 allow for fine-tuning of the engagement position with the steel mesh mold 5. A retaining ring 3 limits the steel mesh mold 5 from the outside, preventing it from disengaging from the hooks 12. A limiting groove 15 is located on the outside of the corresponding hook 12, and the distance between the limiting groove 15 and the hook 12 is equal to or slightly greater than the thickness of the reinforcing plate of the steel mesh mold 5.

[0044] Furthermore, the retaining ring 3 is an elastic circular ring or an elliptical ring.

[0045] The design of the retaining ring 3 of the elastic circular or elliptical ring allows it to be deformed by squeezing during installation and inserted into the limiting groove 15. When released, it can be well fixed in the limiting groove 15 under the action of elastic deformation force, making installation convenient. Similarly, it is also very convenient to remove or adjust, reducing the difficulty of installation.

[0046] Furthermore, the diameter of the elastic ring is 2 / 3 to 4 / 5 of the relative spacing of the limiting grooves 15.

[0047] Furthermore, the major axis of the elastic elliptical ring is 3 / 4 to 4 / 5 of the relative spacing of the limiting grooves 15, or the minor axis is 1 / 3 to 3 / 5 of the relative spacing of the limiting grooves 15.

[0048] The above-mentioned diameter and major and minor axis lengths are designed to meet the requirements of clamping force and ensure the limit requirements.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
