Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a protective layer cushion block for a cast-in-place pile reinforcement cage. Background Art

[0002] As the most common construction technology in pile foundation construction, bored piles are used very frequently in the industry. The biggest advantage of this type of pile is that it can be applied to various geological conditions. Whether it is soft soil, silt, sand or rock, bored piles can be used for construction. Compared with prestressed high-strength concrete pipe piles, manually dug piles and other pile types that have more stringent geological conditions, bored piles are easy to construct and less affected by geological factors, and have better manual controllability.

[0003] The core skeleton of the bored pile is the steel cage, which consists of the main reinforcement of the pile body, reinforcement hoops, hoops, steel cage lifting ears, main reinforcement protection layer pads, etc. Among them, the main reinforcement protection layer pads are mainly used to fix the position of the main reinforcement to prevent the main reinforcement from being exposed, and to ensure that the main reinforcement is evenly wrapped by the bored pile concrete so that its stress performance reaches the optimal state.

[0004] However, the commonly used main reinforcement protection layer pads are mainly made of smaller diameter steel bars processed by a steel bar bending machine, and the two ends are welded to the main bars. During the welding process, the main bars are easily burned, which has a great impact on the stress of the main bars of the steel cage. Moreover, the quality of the steel bars during bending is uneven, and the thickness of the steel cage protection layer is difficult to control. The cost of using steel bars as main reinforcement protection layer pads is relatively high. Utility Model Content

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0025] Reference Figures 1 to 4 An example of the utility model provides a protective layer pad for a cast-in-place pile reinforcement cage, comprising two components 100, each of which is provided with a receiving groove 110 on one opposite side of the two components 100. The two components 100 are connected by a connecting piece 120, and the receiving grooves 110 on the two components 100 are combined to form a fixing hole, and the main reinforcement is fixed in the fixing hole, thereby avoiding welding between the pad and the main reinforcement 180 and improving the overall structural strength of the reinforcement cage.

[0026] Furthermore, the component 100 is an overall U-shaped structure, and a receiving groove 110 is provided at both ends of the component 100. The receiving grooves 110 at both ends of the two components 100 correspond to each other one by one, so that the connection between the cushion block and the main reinforcement 180 is more firmly established. The outer wall of the component 100 is smooth and round, which can prevent the cushion block from scraping against the hole wall and bringing soil into the bottom of the hole.

[0027] Furthermore, the receiving groove 110 is an arc-shaped groove, and the two arc-shaped grooves arranged opposite to each other cooperate to form a hole with the same diameter as the main rib 180 , so that the inner wall of the arc-shaped groove fits better with the outer surface of the main rib 180 .

[0028] The connecting member 120 includes a protrusion 130 and a recess 140 for the protrusion 130 to be inserted into. The protrusion 130 and the recess 140 are snap-connected. The protrusion 130 is arranged on one of the components 100, and the recess 140 is arranged on the other component 100. During installation, the two components 100 can be connected together without using other tools, which greatly improves the installation efficiency of the gasket.

[0029] A plurality of convex portions 130 and concave portions 140 are provided, respectively, so that the connection between the two components 100 is more firmly established.

[0030] Specifically, the protrusion 130 is a pin, and the recess 140 is a pin hole, so that processing and assembly are convenient.

[0031] The pin hole may be a through hole or a blind hole, which is not limited in this embodiment.

[0032] Furthermore, bosses 150 are provided on both sides of the opening of the accommodating groove 110, and convex portions 130 or concave portions 140 are provided on the bosses 150. When the two relatively arranged accommodating grooves 110 cooperate, there is a clamping force on both sides of the accommodating grooves 110 to clamp the main rib 180, thereby firmly fastening the two components 100 to the main rib 180.

[0033] Furthermore, the component 100 is also provided with a plurality of connecting holes 160. The connecting holes 160 on the two components 100 correspond one to one. After the protrusion 130 is inserted into the recess 140, the two relatively arranged connecting holes 160 can be positioned so that the two connecting holes 160 are connected. The two connecting holes 160 can be tied together by the wire 170. Specifically, one end of the wire 170 passes through the two connecting holes 160 and then is tied together, so that the two components 100 are fastened together, thereby further improving the firmness of the gasket.

[0034] It should be noted that the iron wire 170 may also be replaced by a connecting item such as a strap that can pass through the connecting hole 160 and be tied tightly.

[0035] Furthermore, the protrusions 130 and the connection holes 160 are symmetrically arranged along the central axis of the components 100 , so that the clamping force between the two components 100 is evenly distributed.

[0036] Furthermore, the component 100 is made of engineering plastics, which can greatly reduce the manufacturing cost. It has great strength and rigidity and can withstand the impact force between the steel cage and the hole wall during the process of lowering the steel cage into the hole.

[0037] Moreover, the component 100 is integrally formed, which is convenient for mass production, standardizes the overall structure, and improves the thickness accuracy of the steel cage protective layer, thereby improving the construction quality.

[0038] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
