Description

Technical Field

[0001] The utility model belongs to the technical field of cast-in-place pile reinforcement cage construction, and particularly relates to a steel lattice column type reinforcement inserter. Background Art

[0002] Bored and cast-in-place piles (referred to as "cast-in-place piles") have changed the traditional construction method of placing a steel cage before pouring concrete after drilling. It is a pile construction method in which the long spiral drill is used to drill a hole while pouring concrete, and then the steel cage is lowered after the drill is lifted. This method has low construction noise, no vibration, no mud pollution, little waste soil, and no impact on the constructed piles. It is a new type of pile with high practical value. However, when lowering the steel cage, due to the influence of concrete resistance, external force must be used to solve the resistance of the inserted reinforcement, which affects the construction quality.

[0003] At present, the rebar inserters on the market are usually steel pipe type rebar inserters. As the name suggests, the insertion mainly relies on the steel pipe connected to the vibrating hammer to insert the rebar. Since the steel pipe is a relatively closed system, a large amount of concrete is squeezed out during the insertion process, and the resistance increases rapidly with the deepening of the insertion depth. The insertion depth of the steel cage is limited, and voids are formed in the concrete during the steel pipe pulling process. Summary of the invention

[0004] The present application provides a steel lattice column type rebar inserter to solve the problems of large amount of concrete extrusion and large resistance when a steel pipe type rebar inserter is used to rear-insert a steel cage in the prior art.

[0005] The present application provides a steel lattice column type reinforcing bar inserter, which is characterized by comprising:

[0006] The conductive steel plate has a connection structure capable of being connected to the main reinforcement of the steel cage;

[0007] A steel lattice column casing, wherein the steel lattice column casing is a square cylinder, and the upper opening is fixedly connected to the lower surface of the conductive steel plate;

[0008] The steel lattice column has its upper end inserted into the steel lattice column sleeve box and fixedly connected, and the outer diameter of the steel lattice column is smaller than the inner diameter of the steel cage.

[0009] The above-mentioned steel lattice column type rebar inserter is composed of a conductive steel plate, a steel lattice column sleeve and a steel lattice column. The steel lattice column is used to replace the steel pipe in the steel tube type rebar inserter, and is connected with the main rebar of the steel cage through the conductive steel plate. The steel cage is inserted into the concrete through the steel lattice column. Due to the open structure of the steel lattice column, the concrete extrusion is small when the steel cage is inserted later, and thus the resistance is also small, which effectively solves the problem of large concrete extrusion and large resistance when the steel cage is inserted later using the steel tube type rebar inserter in the prior art.

[0010] In the technical solution of one embodiment, the conductive steel plate is circular or square, and its outer diameter is greater than or equal to the outer diameter of the steel lattice column casing.

[0011] In the technical solution of one embodiment, the conductive steel plate is provided with a plurality of rebar insertion holes, and the plurality of rebar insertion holes are distributed in a circular shape, and the diameters thereof directly match those of the steel cage.

[0012] In the technical solution of one embodiment, the number and distribution of the reinforcement insertion holes match the number and distribution of the main reinforcements of the reinforcement cage.

[0013] In the technical solution of one embodiment, when the upper end of the main reinforcement of the steel cage passes through the reinforcement insertion hole, the upper end thereof is fixedly connected to the conductive steel plate through a plurality of nuts.

[0014] In the technical solution of one embodiment, the steel lattice column sleeve is welded to the conductive steel plate, and the steel lattice column sleeve is connected to the steel lattice column by bolts.

[0015] In the technical solution of one embodiment, the lower end of the steel lattice column is a pointed structure.

[0016] In the technical solution of one embodiment, the length of the steel lattice column is the same as the length of the steel cage.

[0017] In the technical solution of one embodiment, a vibrating splint is welded to the upper surface of the conductive steel plate, and the vibrating splint has a hanging ring structure formed by the splint.

In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are listed below.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0027] See also Figure 1 and Figure 2The embodiment of the present application provides a steel lattice column type rebar inserter, which is mainly used to provide an external force to insert the rebar cage into the concrete when the rebar cage is placed later, thereby improving the construction quality and efficiency. The steel lattice column type rebar inserter mainly includes a conductive steel plate 10, a steel lattice column sleeve box 20 and a steel lattice column 40. Among them, the conductive steel plate 10 has a connection structure that can be connected to the main rebar 50 of the rebar cage. The steel lattice column sleeve box 20 is a square cylinder type, fixed on the lower surface of the conductive steel plate 10, and the lower end opening faces downward. The upper end of the steel lattice column 40 is inserted into the steel lattice column sleeve box 20 and is fixedly connected to the steel lattice column sleeve box 20. The outer diameter of the steel lattice column 40 is smaller than the inner diameter of the rebar cage, which is convenient for insertion into the rebar cage. The steel lattice column type rebar inserter is composed of a conductive steel plate 10, a steel lattice column casing 20 and a steel lattice column 40. The steel lattice column 40 is used to replace the steel pipe in the steel tube type rebar inserter, and is connected to the main rebar 50 of the steel cage through the conductive steel plate 10. When in use, the steel lattice column 40 is inserted into the steel cage, and the upper end of the main rebar 50 of the steel cage is connected to the conductive steel plate 10 to form a whole. The whole formed by the steel cage and the steel lattice column type rebar inserter is hoisted above the concrete, and the steel lattice column 40 is pressed down to insert the steel cage into the concrete. Due to the open structure of the steel lattice column 40, the concrete extrusion is small when the steel cage is inserted, and thus the resistance is also small, which well solves the problem of large concrete extrusion and large resistance when the steel cage is inserted after the steel cage is inserted using the steel tube type rebar inserter in the prior art.

[0028] It is understandable that when the steel lattice column casing 20 is designed into a square cylinder shape, in order to match the shape of the steel lattice column 40 and facilitate the connection of the steel lattice column 40, it also imposes certain restrictions on the steel lattice column 40 to prevent rotation.

[0029] Specific to Figure 1 and Figure 2 In the illustrated embodiment, the conductive steel plate 10 may be specifically designed to be circular or square, with an outer diameter greater than or equal to the outer diameter of the steel lattice column casing 20, and preferably completely covering the outer diameter of the steel cage.

[0030] In some embodiments, one or more than two reinforcing bar insertion holes 11 may be provided on the conductive steel plate 10, and the inner diameter of the reinforcing bar insertion hole 11 is slightly larger than the diameter of the main reinforcing bar 50 of the reinforcing cage, and is used to be fixedly connected with the upper end of the main reinforcing bar 50 of the reinforcing cage, providing a relatively simple connection structure. When the number of reinforcing bar insertion holes 11 is more than two, all reinforcing bar insertion holes 11 are distributed in a circular shape, and the circle formed by all reinforcing bar insertion holes 11 matches the circle of the reinforcing cage, ensuring that the reinforcing bar insertion hole 11 can be smoothly plugged with each main reinforcing bar 50 of the reinforcing cage.

[0031] Furthermore, the reinforcing bar insertion holes 11 are preferably evenly distributed so that the reinforcing bar cage can be evenly stressed.

[0032] In some embodiments, the number and distribution of the reinforcement holes 11 are the same as the number and distribution of the main reinforcement bars 50 of the reinforcement cage, specifically a one-to-one correspondence, to ensure that all reinforcement holes 11 can be smoothly plugged into each main reinforcement bar 50 of the reinforcement cage. All the main reinforcement bars 50 of a reinforcement cage are connected to the conductive steel plate 10, which can ensure the integrity of the reinforcement cage during the insertion process.

[0033] When the upper end of the main reinforcement 50 of the steel cage passes through the reinforcement insertion hole 11, its upper end can be fixedly connected to the conductive steel plate 10 through a plurality of nuts, and the clamping and fixing connection through a plurality of nuts facilitates the removal of the steel lattice column reinforcement inserter after the reinforcement cage is inserted. Of course, other methods such as electric welding can be used for fixed connection.

[0034] In some embodiments, the steel lattice column sleeve 20 is welded to the conductive steel plate 10 to ensure the integrity of the steel lattice column sleeve 20 and the conductive steel plate 10; the steel lattice column sleeve 20 is connected to the steel lattice column 40 by bolts, which is convenient for assembly and disassembly, and also convenient for storage and replacement.

[0035] In some embodiments, the steel lattice column 40 can be a lattice column commonly used in the prior art that is welded from angle steel and tie plates. For convenience, in order to further reduce the downward insertion resistance, the angle steel and tie plates at the bottom of the steel lattice column 40 are set to be inclined, wedge-shaped or other pointed structures.

[0036] In some embodiments, the length of the steel lattice column 40 is the same as the length of the steel cage. When in use, the steel lattice column 40 should be directly inserted into the bottom of the steel cage to transmit downward pressure for the steel cage to be inserted downward.

[0037] In some embodiments, a vibrating splint 30 is welded on the upper surface of the conductive steel plate 10, and the vibrating splint 30 has a hanging ring structure. By welding the vibrating splint 30, when in use, the vibrating splint 30 is connected to the vibrating hammer to transmit the downward pressure required for inserting the reinforcement, and provides vibration when pulling out the steel lattice column 40 to ensure the compactness of the concrete; and the hanging ring structure is designed to facilitate lifting.

[0038] In summary, the steel lattice column type rebar inserter provided by the utility model is composed of a conductive steel plate 10, a steel lattice column sleeve 20 and a steel lattice column 40 to form a rebar inserter, and a steel lattice column 40 is used to replace the steel pipe in the steel pipe type rebar inserter, and is connected to the main rebar 50 of the steel cage through the conductive steel plate 10. Compared with the prior art, it has the following beneficial effects:

[0039] 1. The installation process is safe and environmentally friendly. The entire installation process is completed on the ground. The installation can be completed by simply connecting and fixing the steel lattice column 40 and the steel lattice column sleeve box 20.

[0040] 2. The processing materials are easy to obtain, the cost is economical, and the conditions for large-scale promotion are met. The angle steels, steel plates, etc. required by the utility model are all commonly used materials in construction projects and are met for large-scale use.

[0041] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people.
