Description

[0002] With the improvement of environmental protection requirements, at present, the wooden railing of transmission is being replaced by the imitation wood railing, and the imitation wood railing is widely used in parks, scenic spots and the like to improve the environmental awareness and protect the beautification and environmental protection. The imitation wood railing structure includes a base plate as a base, a stand column fixed on the upper part of the base plate and a railing connected with the stand column.

[0003] During construction, the base plate needs to be poured with concrete, and the reinforcing bar for supporting the stand column framework needs to be reserved at the same time of pouring the base plate, that is, a straight reinforcing bar. During vibrating the concrete, the reinforcing bar is easy to deviate and collapse. Since the reinforcing bar is fixed by binding wire, it is difficult to rebind in the just-poured concrete. Moreover, after the concrete is initially cured, adjusting the reinforcing bar is easy to cause cracks at the root of the reinforcing bar due to the fact that the strength of the concrete does not reach the design requirement at this time. If the reinforcing bar is not timely righted during the vibrating process, the reinforcing bar can only be planted in the later stage, which increases the labor and material costs.

[0004] Therefore, how to fix the reinforcing bar plate has become a technical problem to be solved. SUMMARY

In addition, all combinations of features described in the embodiments are not necessarily required by the solutions of the invention.

[0029] It should be understood by those of ordinary skill in the art that all directional references (e.g., upper, lower, upward, up, downward, down, top, bottom, left, right, vertical, horizontal, etc.) are descriptive used in the drawings to assist the reader in understanding, and do not indicate (e.g., to position, orientation, or use) limitations on the scope of the invention defined by the appended claims. In addition, the term "substantially" can refer to slight inaccuracy or slight deviation of conditions, quantities, values or dimensions, some of which are within the range of manufacturing deviation or tolerance.

[0030] Example One

[0031] As Figures 1 to 6As shown, a reinforcing bar fixing seat is used for fixing reinforcing bars 1 and connecting bars inside a cast structure. In this embodiment, a bionic railing is taken as an example. The reinforcing bars 1 are support bodies inside railing uprights, and the connecting bars are framework bodies inside a bottom plate.

[0032] The reinforcing bar fixing seat comprises a fixing module, which is provided with a positioning hole in the up-down direction for inserting the reinforcing bars 1. The positioning hole is provided with a guide groove 501 for the connecting bars to pass through, so that the reinforcing bars 1 can pass through between the connecting bars and the inner wall of the positioning hole, thereby the reinforcing bars 1 can be pre-fixed before pouring concrete, preventing the reinforcing bars 1 from being inclined when pouring the bottom plate, eliminating the problems of the reinforcing bars 1 deviating and falling during concrete vibration, avoiding the problem of cracks in the concrete at the root of the reinforcing bars 1 when adjusting the position of the reinforcing bars 1 deviated and fallen, and avoiding the increase in cost due to the late reinforcing bars when the position of the reinforcing bars 1 cannot meet the construction requirements through adjustment.

[0033] The fixing module comprises a cylindrical cavity 4, and the positioning hole comprises an upper positioning hole 5 located above the cylindrical cavity 4. The upper positioning hole 5 is circumferentially uniformly distributed with a plurality of guide grooves 501 for the upper connecting bars of the bottom plate to pass through. In this embodiment, the guide grooves 501 are four. Among them, two horizontally opposite guide grooves 501 are for horizontal connecting bars 6 to pass through, and two vertically opposite guide grooves 501 are for vertical connecting bars 7 to pass through. The horizontal connecting bars 6 and the vertical connecting bars 7 are perpendicular to each other.

[0034] The depth of the guide groove is greater than the sum of the diameters of the horizontal connecting bars 6 and the vertical connecting bars 7, so as to facilitate the vertical connecting bars 7 and the horizontal connecting bars 6 to pass through the guide grooves 501 in an up-down staggered manner.

[0035] The cylindrical cavity 4 is also circumferentially uniformly distributed with a plug hole 401 for the bottom connecting bars of the bottom plate to pass through. The depth of the plug hole 401 is greater than the sum of the diameters of the horizontal connecting bars 6 and the vertical connecting bars 7.

[0036] The positioning hole further comprises a lower positioning hole 8 located inside the cylindrical cavity 4. The upper positioning hole 5 and the lower positioning hole 8 are coaxial and correspond to each other in the up-down direction.

[0037] The upper end of the cylindrical cavity 4 and the upper positioning hole 5 are communicated through a first outward tapered cavity 9, that is, the first outward tapered cavity 9 is located outside the upper end of the cylindrical cavity 4. The bottom of the first outward tapered cavity 9 is communicated with the upper end of the cylindrical cavity 4, and the top is communicated with the upper positioning hole 5. The lower end of the cylindrical cavity 4 and the upper positioning hole 5 are communicated through a second inward tapered cavity 10, that is, the second inward tapered cavity 10 is located inside the cylindrical cavity 4. The bottom of the second inward tapered cavity 10 is communicated with the lower end of the cylindrical cavity 4, and the top is communicated with the lower positioning hole 8.

[0038] The cylindrical cavity 4 is provided with a feeding port for communication between the inside and outside of the cavity, four upper feeding ports 11 are distributed on the first tapered cavity 9 and the second tapered cavity 10, and side feeding ports 402 are distributed on the circumferential side wall of the cavity, so that the concrete can enter the cylindrical cavity 4 when pouring concrete. The bottom end of the embedded bar 1 is bent to avoid the embedded bar 1 from being separated from the positioning hole.

[0039] As shown in Figure 7 , 8 The embedded bar fixing seat includes a plurality of upper and lower stacked fixing modules. The second tapered cavity 10 of the upper fixing module can be sleeved on the first tapered cavity 9 of the lower fixing module, so that the upper and lower modules are firmly connected, the positioning holes of the upper and lower fixing modules are communicated, and multiple layers of connecting bars can be arranged. The embodiment shows two upper and lower stacked fixing modules, so that three layers of connecting bars can be arranged. Of course, the number of layers can be designed according to actual construction needs.

[0040] Since the embedded bar fixing seat structure is complex and it is required to be made of the same concrete material as the bottom plate as much as possible, the fixing module is a D-printed forming piece. It can be customized according to the site conditions to be suitable for different embedded bar 1 diameters, different plate thicknesses, different plate bottom bar diameters, and different plate top bar diameters. It is simple to make, low in cost, and low in process requirement; it is easy to use and is not affected by construction time, improving construction efficiency.

[0041] The key of the fixing module D printing forming method is how to determine the inner diameter of the positioning hole. In the embodiment, the following method is adopted: first, the diameters of the embedded bar 1, the longitudinal connecting bar 7 and the transverse connecting bar 6 are determined; then, when the diameters of the embedded bar 1, the longitudinal connecting bar 7 and the transverse connecting bar 6 are perpendicular to each other and the embedded bar 1 is tangent to the longitudinal connecting bar 7 and the transverse connecting bar 6, the intersection of the longitudinal connecting bar 7 and the transverse connecting bar 6 is taken as the center of a circle, and the diameter of a circle that is inscribed in the cross-sectional circle of the embedded bar 1 is determined. The diameter is the inner diameter of the positioning hole. The inner diameter of the positioning hole thus determined can make the embedded bar 1 be clamped between the connecting bar and the inner wall of the positioning hole and remain upright.
