Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering accessories, in particular to a demountable fastener for a steel bar truss with good adaptability. Background Technique

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their ancillary facilities and the installation activities of the pipelines and equipment supporting them. Among them, "housing building" refers to a project with a roof, beams, columns, walls, foundation, and capable of forming an internal space to meet the needs of people's production, residence, study, and public activities. During the construction of construction engineering, many construction workpieces are often used, and the truss is one of them, and the truss will be used in cooperation with the bottom plate and fasteners.

[0003] However, since the steel bars in the truss are different in size, it is necessary to process and produce different types of fasteners for use, which is not convenient and the economic cost is relatively high. Summary of the Invention

[0004] The technical problem to be solved by the utility model is that: the steel bars of the truss are different in size, and different types of fasteners are required for use, which is not convenient and the economic cost is relatively high.

[0005] To solve the above problems, the technical solution adopted by the utility model is: a demountable fastener for a steel bar truss with good adaptability, including a fastener body, an L-shaped clamping member, a cross-shaped limiting through hole, and a limiting clamping member. The fastener body is in the shape of a long plate. Two L-shaped clamping members are integrally connected to the top surface of the fastener body. One L-shaped clamping member is located at the upper left end of the fastener body, and the other L-shaped clamping member is located on the top surface of the right half of the fastener body. A clamping groove for fixing the steel bar is formed between the L-shaped clamping member and the fastener body;

[0006] A cross-shaped limiting through hole is opened at the right end of the L-shaped clamping member on the right half of the fastener body, and a limiting clamping member can be inserted into the cross-shaped limiting through hole. The cross section of the limiting clamping member is in the shape of a "T";

[0007] Two threaded holes are respectively opened at the left and right ends of the bottom surface of the fastener body, and locking bolts are threadedly connected in the threaded holes.

[0008] The protrusion of the limiting clamping member is an extrusion fixing member, and there are various types of limiting clamping members, and the lengths of the extrusion fixing members of different types of limiting clamping members are different.

[0009] A rectangular through hole is opened in the middle of the fastener body.

[0010] The beneficial effects of the present utility model are as follows: The limit card of this detachable fastener for steel bar trusses can be used in combination with the cross-shaped limit through-hole to fix steel bars of various models. To fix steel bars of different models, only the limit card needs to be replaced, with a lower replacement cost and more convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0016] As Figure 1 shown, a detachable fastener for steel bar trusses with good adaptability includes a fastener body 1, an L-shaped card 2, a cross-shaped limit through-hole 3 and a limit card 4. The fastener body 1 is in the shape of a long plate. Two L-shaped cards 2 are integrally connected to the top surface of the fastener body 1. One L-shaped card 2 is located at the upper left end of the fastener body 1, and the other L-shaped card 2 is located on the top surface of the right half of the fastener body 1. A card slot for fixing steel bars is formed between the L-shaped card 2 and the fastener body 1;

[0017] A cross-shaped limit through-hole 3 is provided at the right end of the L-shaped card 2 in the right half of the fastener body 1. The cross-shaped limit through-hole 3 can be inserted with a limit card 4. The cross-section of the limit card 4 is in the shape of a "T"; when the convex side of the limit card 4 faces left and is inserted into the cross-shaped limit through-hole 3 and is stuck, it can be adapted to fix steel bars with smaller sizes. When the convex side of the limit card 4 faces right and is inserted into the cross-shaped limit through-hole 3, it can be adapted to fix steel bars with larger sizes

[0018] Two threaded holes 5 are respectively provided at the left and right ends of the bottom surface of the fastener body 1. Locking bolts are threadedly connected in the threaded holes 5. This fastener is fixed on the floor slab through the locking bolts.

[0019] The convex part of the limit card 4 is an extrusion fixing part. There are various models of the limit card 4, and the lengths of the extrusion fixing parts of different models of the limit card 4 are different; the inconsistent lengths of the extrusion fixing parts of the limit card 4 can be adapted to more models of steel bars.

[0020] A rectangular through-hole starts from the middle of the fastener body 1.
