Abstract
The utility model provides a pre-buried device for can dismantle bracket, its characterized in that: the device comprises at least four lengthened nuts, at least four connecting screw rods and at least four plug anchor plates; four screw rod openings are formed in the periphery of each lengthened nut, the lengthened nuts are connected and fixed through a connecting screw rod, and a plug anchor plate is welded to the back face of each lengthened nut. During the use, can will as required the utility model discloses an in pre-buried device buries concrete structure thing 7 to make 1 mouthful of and concrete face parallel and level of extension nut, steel bracket 6 adopts high-strength bolt 5 to be connected with pre-buried device's extension nut 1. When the bracket 6 is dismantled in the later stage, the bracket can be recovered, only the embedded device is consumed, the construction cost is saved, and the influence on the appearance of the concrete is small.
Description
Technical Field
The utility model belongs to the civil engineering field, concretely relates to a pre-buried device for can dismantle bracket.
Background
In the construction process of woodworking, a common construction method is to install a steel corbel on the existing concrete structure as a support. The steel bracket is generally welded with an embedded part or connected with an embedded creeping cone by a bolt.
The steel bracket adopts a welding connection mode with an embedded part, and has the following problems that (1) the on-site welding time of the steel bracket is long, and the welding quality is difficult to control; (2) the steel corbels are removed by cutting, so that the steel corbels are difficult to recycle and have high cost; (3) the embedded steel plates are embedded in the surface of the concrete, concrete burning is easily caused in the welding process, and the appearance quality of the concrete is poor.
The steel bracket adopts the bolt and pre-buried awl connected mode of climbing to have following problem: (1) the embedding precision of the climbing cone is difficult to control; (2) the weight of a single creeping cone is larger, and the construction cost is higher.
Disclosure of Invention
The utility model discloses a problem and the defect of the existence of above-mentioned prior art of overcoming provide a pre-buried device for can dismantle bracket, have that construction cost is low, the material is purchased conveniently, the installation accuracy is high, do not influence advantages such as concrete outward appearance, effectively solved the problem that exists among the background art.
The utility model provides a pre-buried device for can dismantling bracket which characterized in that: the device comprises at least four lengthened nuts, at least four connecting screw rods and at least four plug anchor plates; four screw rod openings are formed in the periphery of each lengthened nut, the lengthened nuts are connected and fixed through a connecting screw rod, and a plug anchor plate is welded to the back face of each lengthened nut.
The embedded lengthened nut port is flush with the concrete surface.
When the steel corbel is used, the lengthened nuts can be embedded into a concrete structure after being combined according to needs, the openings of the lengthened nuts are flush with the concrete surface, and the steel corbels are connected with the lengthened nuts of the embedded device through high-strength bolts. Recoverable steel bracket when steel bracket later stage is demolishd only consumes pre-buried device, practices thrift construction cost and just little to the concrete outward appearance influence.
The utility model has the advantages that: (1) the embedded device is a lengthened nut, a connecting screw rod and a plug anchor plate, the lengthened nut needs to be provided with a screw rod opening and is subjected to threading, the material is convenient to purchase, and the processing is convenient; (2) the lengthened nuts can be combined into a whole through the connecting screw rod according to the requirement, and the embedding precision is high; (3) the steel bracket is connected with the lengthened nut of the embedded device through the high-strength bolt, so that the connection is reliable and firm; (4) after the construction is finished, the steel corbels can be disassembled and recycled, so that the construction cost is reduced; (5) the bolt hole accessible grout material shutoff on concrete surface is little to concrete outward appearance influence.

Fig. 1 is a structural view of the present invention.
Fig. 2 is a single structure view of the extension nut of the present invention.
Fig. 3 is a schematic cross-sectional view of the present invention.
Reference numerals: 1-lengthened nut, 2-screw mandrel mouth; 3-connecting screw rods, 4-plug anchor plates, 5-high-strength bolts, 6-steel brackets and 7-concrete structures.
Detailed Description
The utility model is explained in detail with the attached drawings as follows:
as shown in fig. 1 and 2, the utility model comprises nine lengthened nuts 1, twelve connecting screw rods 3 and nine plug anchor plates 4; four screw rod openings 2 are formed around each lengthened nut 1 and are used for threading, two adjacent lengthened nuts 1 are fixedly connected through a connecting screw rod 3, and a plug anchor plate 4 is welded on the back surface of each lengthened nut 1. During the use, as shown in fig. 3, can will as required the utility model discloses a pre-buried device buries in concrete structure thing 7 to make extension nut mouth and concrete face parallel and level, steel bracket 6 adopts high-strength bolt 5 to be connected with pre-buried device's extension nut 1. When 6 later stages of steel corbels are demolishd, it is recoverable, only consume pre-buried device, the bolt hole accessible grouting material shutoff on concrete surface practices thrift construction cost and little to the concrete outward appearance influence.
The specific implementation process of the embedded device for the detachable bracket is specifically described as follows:
(1) determining the length and the number of the lengthened nuts 1 according to the calculation result;
(2) assembling the lengthened nut 1 into a whole by adopting a connecting screw rod 3 according to requirements, welding a plug anchor plate 4 on the back surface, plugging concrete and increasing the anchoring force of the pre-embedded device, and installing the pre-embedded device into a concrete structure 7 to be poured and fixing;
(3) pouring concrete, enabling the nut port to be flush with the concrete surface, removing the template after the pouring of the concrete is finished, and fixing the steel corbel 6 with the lengthened nut 1 of the pre-embedded device by adopting a high-strength bolt 5;
(4) and after the construction is finished, the high-strength bolt 5 is disassembled to disassemble the steel bracket 6, and the steel bracket 6 can be recycled. The bolt hole accessible grout material shutoff on concrete surface is little to concrete outward appearance influence.
The aforesaid does the utility model discloses a main construction flow, the utility model discloses can be used to install the pre-buried device that the steel corbel supported on current concrete structure.
