Abstract
The utility model relates to a hollow concrete square pile. Square end head plates are arranged at two ends and the two end head plates are connected through a reinforcement cage. The hollow concrete square pile is characterized in that the reinforcement cage is formed by braiding vertical steel bars and transverse winding steel bars; 12 vertical steel bars are uniformly distributed along the square periphery of the vertical section in the vertical length direction of the reinforcement cage; one vertical steel bar is arranged at each corner of the vertical section of the reinforcement cage; and four vertical steel bars are arranged at each edge of the vertical section and 12 vertical steel bars are arranged; the transverse winding steel bars are distributed on the reinforcement cage along the vertical length direction at a certain distance; and the transverse winding steel bars and the 12 vertical steel bars are braided into a cubic structure. According to the hollow concrete square pile, the use amount of concrete is less compared with that of a solid square pile body; compared with all pile main ribs, the use amount is less; and compared with other piles with the same diameter or edge length, the flexural rigidity is great.
Description
Technical field
The utility model relates to a kind of architectural prefab, relates in particular to the stake of a kind of hollow concrete side.
Background technology
Have a lot of concrete prefabricated side's stakes to be applied in the middle of the building operations at present, existing hollow square pile is generally non-prestressed prefabricated units, and anti-bending strength is relatively poor, in processes such as lifting, transportation, transhipment, construction, is prone to cause pile body crack even fracture to occur.Simultaneously, owing to adopt the shaping of vibrating usually, concrete strength grade is generally C30～C40, and the pile body structural bearing capacity is lower, and the external form physical dimension is irregular, is prone in the construction clip broken, and breakage rate is high, and the pile body steel using amount is big, and is uneconomical.
Summary of the invention
For solving above-mentioned technical problem; The utility model provides a kind of hollow concrete square pile; Be provided with square end plate at its two ends, connect mutually with reinforcing cage between the two ends plate, it is characterized in that: braiding forms said reinforcing cage with horizontal winding reinforcing bar by many longitudinal reinforcements.
In technique scheme, the square perimeter of the longitudinal cross-section, longitudinal length direction upper edge of said reinforcing cage is evenly distributed with many longitudinal reinforcements.
In technique scheme, each place, angle of the longitudinal cross-section of said reinforcing cage is provided with all has a longitudinal reinforcement, and every limit of longitudinal cross-section is provided with four longitudinal reinforcements, is provided with 12 longitudinal reinforcements altogether.
In technique scheme; Said reinforcing cage is longitudinally keeping at a certain distance away on the length direction; The said horizontal winding reinforcing bar that distributing, said horizontal winding reinforcing bar is spirally wound on the outside of said longitudinal reinforcement, and said horizontal winding reinforcing bar is woven into cube structure with 12 longitudinal reinforcements.
In technique scheme, between said two ends plate, the concrete that wraps reinforcing cage forms the pile body of hollow concrete square pile, the surface of said hollow concrete square pile is shiny surface or textured.
The utility model has been obtained following technique effect:
1, the utility model is high with respect to pile tube Φ 400, solid side's pilework bearing capacity.
2, the utility model is big with respect to pile tube Φ 400, pile tube Φ 500 bearing capacity of foundation soil.
3, the utility model is few with respect to solid side's stake concrete piles consumption.
4, the utility model is few with respect to all piles master muscle consumption.
5, the utility model is big with respect to other bending rigidities of the equivalent diameter or the length of side.
Description of drawings
Fig. 1 is the lateral view of the bar construction of hollow concrete square pile;
Fig. 2 is the top view of the bar construction of hollow concrete square pile.
Mark among the figure: 10-end plate; The 11-longitudinal reinforcement; 12-laterally twines reinforcing bar.
The specific embodiment
Understand and enforcement the utility model for the ease of those of ordinary skills, the utility model is done further to describe in detail below in conjunction with the accompanying drawing and the specific embodiment.
Shown in Fig. 1-2, the hollow concrete square pile of the utility model, the longitudinal length two ends of stake are provided with square end plate 10 in the side, and two ends plate 10 usefulness longitudinal reinforcements 11 connect with the reinforcing cage that horizontal winding reinforcing bar 12 is woven into mutually.The two ends of all longitudinal reinforcements are fastened on respectively on the end plate at two ends, for hollow concrete square pile provides enough longitudinal strengths.Between the two ends plate, wrap the concrete side of formation stake pile body of reinforcing cage.Hollow concrete square pile surface is shiny surface or textured.Between the two ends plate, the concrete that wraps reinforcing cage can be the concrete of hollow method moulding.
As shown in Figure 2; The longitudinal length direction upper edge square sectional periphery of hollow concrete square pile is evenly distributed with 12 longitudinal reinforcements 11 altogether, and each place, angle is provided with 1 longitudinal reinforcement 11, and each side has 4 longitudinal reinforcements 11; 12 longitudinal reinforcements 11 are labeled as N1～N12 in the drawings respectively altogether.Reinforcing cage is on length direction longitudinally; Whenever keep at a certain distance away; Be distributed with along laterally twining reinforcing bar 12; Laterally twine the outside that reinforcing bar 12 is spirally wound on 12 longitudinal reinforcements 11, be woven into cube structure, for all directions of hollow concrete square pile provide enough support strengths with 12 longitudinal reinforcements 11.
The used longitudinal reinforcement 11 of reinforcing cage can be prestressed reinforcement or plain bars with the main muscle that laterally twines reinforcing bar 12.Be used to make the pre-stress hollow concrete square pile, used main muscle is a prestressed reinforcement, is used to make common hollow concrete square pile, and used main muscle is a plain bars.
The moulding form of this hollow concrete square pile; Can adopt the pipe die of two make-ups; An identical equilateral right-angled triangle inner chamber of geometry is arranged in the every mould, and after two pipe dies were interlocked with bolt, two equilateral right-angled triangle inner chambers constituted a square inner chamber.Two equilateral right-angled triangles are chamfering for formed square four jiaos.
Above embodiment is merely a kind of embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Its concrete structure, number of steel bars and size can be adjusted according to actual needs accordingly.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
