Description

Technical Field

[0001] This utility model relates to the field of steel mesh fixing structure technology, and in particular to a steel mesh lap splicing structure. Background Technology

[0002] When water supply pipelines are laid through forest areas, boardwalks need to be constructed to support the pipelines. The boardwalks use a combination of anchor cables and steel mesh, and the segmented steel mesh panels usually need to be welded together to form a whole. When the water supply project is located in a forest area, according to relevant regulations, electric welding is strictly prohibited in the forest area because it is considered a productive use of fire and poses a great fire hazard. To avoid the risks of hot work, the steel mesh laid in the concrete slab is connected using a snap-fit ​​mechanical process instead of welding. The snap-fit ​​is made of rust-proof and corrosion-resistant material, which simplifies on-site construction and installation and facilitates subsequent maintenance.

[0003] The steel mesh is formed by the perpendicular intersection of transverse and longitudinal steel bars. The existing snap-fit ​​structure only uses a simple U-shaped structure for winding and fixing, which is time-consuming and has poor fixing effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a steel mesh overlapping structure that avoids open flame operation and is simple to construct and install, and facilitates subsequent maintenance.

[0005] According to an embodiment of the present invention, a steel mesh lap splice structure includes a U-shaped buckle body, the buckle body having two parallel lap arms, a first space for accommodating transverse steel bars being formed between the two lap arms, and connecting arms bent to the same side being provided at the ends of the two lap arms, a second space for accommodating longitudinal steel bars being formed between the lap arms and the connecting arms, and an adjustable abutment plate being detachably connected to the connecting arm, the abutment plate, the transverse steel bars, the longitudinal steel bars, and the lap arms abutting in sequence.

[0006] Preferably, the contact plate has a through hole, and the connecting arm has an external thread that passes through the through hole and is connected to a positioning nut.

[0007] More preferably, a receiving plate is fixed between the two overlapping arms near the connecting arm.

[0008] More preferably, the receiving plate is an arc-shaped plate, and the inner side of the receiving plate is provided with longitudinal anti-slip texture.

[0009] More preferably, the contact plate has an arc-shaped positioning groove on the side near the transverse reinforcing bar.

[0010] More preferably, the positioning groove is provided with transverse anti-slip texture.

[0011] More preferably, the abutment plate has a screw hole on one side and a movable hole coaxially connected to the screw hole on the other side. An adjusting screw is threaded into the screw hole, and an abutment rod extending to the outside and abutting against the end of the buckle body is provided in the movable hole.

[0012] In a further preferred embodiment, the inner side of the end of the buckle body is provided with a slot, and the end of the abutment rod is provided with a plug that can be interference-fitted with the slot.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The U-shaped buckle bends to form lap arms and connecting arms. The lap arm support forms the first space to accommodate the transverse steel bars, and the connecting arm and lap arm form the second space to accommodate the longitudinal steel bars. Through the action of the abutment plate, after installation, the abutment plate and lap arm can stably fix the transverse and longitudinal steel bars on the inside and produce a squeezing effect, so that the position of the transverse and longitudinal steel bars is stable, ensuring the structural stability of the steel mesh.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] This utility model provides an embodiment of a steel mesh lap splice structure, including a U-shaped buckle body 1. The buckle body 1 has two parallel lap arms 110. A first space 111 for accommodating transverse steel bars 2 is formed between the two lap arms 110. The ends of the two lap arms 110 are provided with connecting arms 120 that bend to the same side. A second space 121 for accommodating longitudinal steel bars 3 is formed between the lap arms 110 and the connecting arms 120. The lap arms 110 and the connecting arms 120 on both sides are located on two parallel planes, and the planes are perpendicular to the planes where the two lap arms 110 are located and perpendicular to the planes where the two connecting arms 120 are located.

[0020] An adjustable abutment plate 130 is detachably connected to the connecting arm 120. The position of the abutment plate 130 can be adjusted and fixed along the direction of the connecting arm 120. The abutment plate 130, the horizontal steel bar 2, the longitudinal steel bar 3, and the lap arm 110 abut in sequence.

[0021] After installation and fixing, the contact plate 130 and the lap arm 110 press and fix the transverse steel bar 2 and the longitudinal steel bar 3 together;

[0022] In order to facilitate the adjustment of the position of the contact plate 130, in a further embodiment, the contact plate 130 is provided with a through hole 138, and the connecting arm 120 is provided with an external thread 122 and a positioning nut 123 is connected through the through hole 138.

[0023] In order to ensure the stability of the spacing between the two overlapping arms 110 and improve the structural stability, in a further embodiment, a support plate 112 is fixedly provided between the two overlapping arms 110 near the connecting arm 120, and the support plate 112 is welded to the overlapping arm 110.

[0024] In order to improve the longitudinal stability of the longitudinal reinforcement 3 after lap splicing, in a further embodiment, the receiving plate 112 is an arc-shaped plate, and the inner side of the receiving plate 112 is provided with longitudinal anti-slip texture 113.

[0025] In order to improve the longitudinal stability of the transverse steel bar 2 after lap splicing, in a further embodiment, the abutment plate 130 is provided with an arc-shaped positioning groove 131 on the side near the transverse steel bar.

[0026] To improve the stability of the transverse reinforcing bar 2 in the transverse direction after lap splicing, in a further embodiment, the positioning groove 131 is provided with transverse anti-slip texture 132.
