Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and more specifically relates to a cushion block structure for a pile foundation steel cage and a pile foundation steel cage. Background Art

[0002] During the construction of bridges, culverts or high-rise buildings, the foundation may be required to be piled according to the requirements. The method is to use machine punching and water grinding to drill holes, and the hole depth meets the design requirements, and then lower the steel cage into the pile hole, and then insert the guide tube for concrete pouring. Before lowering the steel cage into the pile hole, it is necessary to install multiple pads on the steel cage. The pads can effectively prevent the steel cage from damaging the lower structure. At the same time, the steel cage is limited, which improves the construction efficiency and ensures the stability of the steel cage, so that the steel cage will not deform or tilt. Traditional pile foundation steel cage pads generally use round pads. After the steel cage is welded, the pads are installed in conjunction with short steel bars and fixed together on the steel cage. This pad structure and installation method requires the staff to re-perform the welding operation, which is slow and inefficient, and has high labor costs. Utility Model Content

[0036] See also Figures 1 to 6 As a specific embodiment of the cushion block structure for pile foundation reinforcement cage provided by the utility model, an adhesive layer for connecting with the elastic sleeve 3 is provided on the upper end surface of the annular flange 2 or the inner wall of the through hole 11; that is, before installing the elastic sleeve 3, the adhesive layer is applied on the upper end surface of the annular flange 2 or the inner wall of the through hole 11, and then the elastic sleeve 3 is installed so that the elastic sleeve 3 is fixedly connected with the cushion block body 1 through the adhesive layer. When the steel bar 5 passes through the installation channel 12 and enters the through hole 11, it will not cause the elastic sleeve 3 to shift, ensuring that the elastic sleeve 3 is tightly stuck into the steel bar 5. The elastic sleeve 3 is made of high elastic plastic, or made of nylon, polyethylene material, etc.

[0037] See also Figures 2 to 5 As a specific embodiment of the cushion structure for pile foundation reinforcement cage provided by the utility model, the annular flange 2 is integrally formed with the cushion body 1, and the lower end surface of the annular flange 2 and the lower end surface of the cushion body 1 are located on the same plane; the connection strength between the annular flange 2 and the cushion body 1 is improved, so that the annular flange 2 is firmly installed on the cushion body 1, and then the elastic sleeve 3 is stably carried. The lower end surface of the annular flange 2 is set flush with the lower end surface of the cushion body 1, so that the space size for installing the elastic sleeve 3 in the through hole 11 is larger, ensuring that the elastic sleeve 3 is stably installed on the through hole 11 and the annular flange 2.

[0038] See also Figures 1 to 5 As a specific implementation of the cushion block structure for pile foundation steel cage provided by the utility model, the upper end of the cushion block body 1 is provided with limiting grooves 14 located on both sides of the installation groove 13, and the two limiting grooves 14 are communicated with the installation groove 13; both sides of the limiting block body 4 are provided with clamping blocks 42 installed in cooperation with the two limiting grooves 14; two limiting grooves 14 are set and respectively located on both sides of the installation groove 13, and the limiting grooves 14 are communicated with the installation groove 13; at the same time, clamping blocks 42 are set on both sides of the limiting block body 4, and after the limiting block body 4 is installed in the installation groove 13, the two clamping blocks 42 are respectively inserted into the two limiting grooves 14, so as to further position the limiting block body 4 and prevent the limiting block body 4 from moving.

[0039] See also Figure 7 and Figure 8 As a specific embodiment of the cushion block structure for the pile foundation steel cage provided by the utility model, there are multiple ribs 41, which are arranged in parallel and spaced apart; multiple ribs 41 are arranged in parallel and spaced apart, and are located on one side surface of the limiting block body 4 close to the through hole 11; therefore, when the limiting block body 4 is installed into the installation groove 13, multiple ribs 41 act on the steel bar 5, so that the steel bar 5 is more firmly placed in the cushion block body 1 and will not move.

[0040] See also Fig.10 As a specific implementation of the cushion block structure for pile foundation steel cage provided by the utility model, the spacing between the side of the rib 41 away from the limiting block 4 and the limiting block 4 gradually increases from bottom to top; through the rib 41 of this structure, during the process of installing the limiting block 4 into the installation groove 13, the size of the cross-section of the rib 41 changes continuously, so that the force of the rib 41 on the steel bar 5 is gradually enhanced to ensure that the steel bar 5 is subjected to greater force.

[0041] See also Figures 7 to 9As a specific embodiment of the cushion block structure for pile foundation steel cage provided by the utility model, the limiting block 4 and the rib 41 are integrally formed, which improves the connection strength between the limiting block 4 and the rib 41, so that the rib 41 can stably act on the steel bar 5. At the same time, when the limiting block 4 is installed in the installation groove 13, when the rib 41 contacts the steel bar 5, the rib 41 reacts on the limiting block 4, so that the rib 41 acts on the steel bar 5 more firmly.

[0042] See also Fig.11 As a specific embodiment of the cushion block structure for pile foundation steel cage provided by the utility model, the longitudinal section of the installation groove 13 is a right-angle trapezoid, and the vertical surface of the installation groove 13 is arranged close to the through hole 11; the limit block body 4 has an inclined protrusion 43 installed in cooperation with the inclined surface of the installation groove 13; when the limit block body 4 is installed in the installation groove 13, the plane of the limit block body 4 is installed in cooperation with the vertical surface of the installation groove 13, and its inclined protrusion 43 is installed in cooperation with the inclined surface of the installation groove 13; in this way, the inclined protrusion 43 on the limit block body 4 increases the weight of the limit block body 4, and also makes the force of the limit block body 4 on the steel bar 5 more reliable, so that the cushion block body 1 and the steel bar 5 are fixedly connected more firmly. A clamping groove is arranged on the bottom surface of the installation groove 13, and a tip portion connected to the clamping groove is arranged at the lower end of the limit block body 4.

[0043] See also Figure 1 and Figure 7 As a specific embodiment of the cushion block structure for pile foundation steel cage provided by the utility model, the cushion block body 1 is made of cement, and the limit block body 4 is made of plastic material. The use of cement to make the cushion block can not only make the entire steel cage firmly supported on the structure by virtue of the hardness of cement, but also not easily damage the structure. The limit block body 4 is made of plastic material, which is light in weight, and the plastic limit block body 4 is deformed when it contacts the steel bar 5, thereby generating strong friction force on the steel bar 5.

[0044] Not shown in the figures, an embodiment of the utility model further provides a pile foundation reinforcement cage, which includes any one of the above-mentioned pad structures for the pile foundation reinforcement cage.

[0045] The pile foundation steel cage provided by the utility model adopts the above-mentioned pad structure for the pile foundation steel cage, so that the pad body 1 and the steel bar 5 are firmly and securely installed together without the need for welding operations, which simplifies the installation steps of the pad body 1, improves the installation speed and efficiency, and reduces labor costs.
