Reinforced structure of concrete stairs and wall panels

[1] This creation relates to a concrete structure of concrete stairs and wall panels, especially a revealer who can improve the joint strength of the stairs and wallboard after grouting, and shorten the innovative structure of the steel structure during the grouting time.

[2] According to the existing construction method of combining reinforced concrete stairs and wall panels, it is usually constructed by two-stage grouting. Please refer to FIG. 1 , which mainly relates to the steel structure of the first bandage wall panel, and extends the series of transverse steel bars 50 at appropriate positions, and reserves holes in the plate mold 60 for the aforementioned transverse steel bars 50 to pass through. That is, the installation of the form mold 60 is started to prepare for grouting. After the mold is demolished, when the steel structure of the stairs is erected, the transverse steel bars 50 of the stairs and the transverse steel bars of the wall panels are overlapped to each other to strengthen the joint strength between the stairs and the wall panels. [3] However, although the steel structure can obtain a complete wall surface in the first grouting operation, although the stair steel bar and the wall plate steel bar are partially overlapped with each other, they are overlapped due to the inherent confinement of the structure. Insufficient length, often caused by serious earthquakes in the joint between the stairs and the wall panel, and even caused collapse, the 921 earthquake is a painful lesson. [4] The concrete grouting method of concrete wallboard and stairs has changed significantly. It mainly cuts the end of the transverse steel bar 50, cuts the appropriate length and bends it into an appropriate angle, and then with the wallboard or beam (main structure) The steel bars are anchored to each other (the binding of the ribs). At this time, because the stair steel bars have been anchored to each other and the grouting bars are mutually anchored, the grouting operation is completed. After the concrete is solidified and the formwork 60 is removed, the method is completed according to this method. The combination of the strength and the shock resistance between the stairs and the wall panels will be greatly improved, and of course, it will be able to withstand the more intense earthquakes. Referring to Figures 2 and 3, such a rib structure will leave a portion 70 that is not covered by the stencil 60 after the slab 60 of the wall panel is placed below the stair and the wall panel. In order to avoid the serious side leakage caused by the wallboard grouting and the hole to affect the structural strength, the field formwork workers usually insert a long elongated wooden strip 61 to try to cover the part not covered by the formwork 60 as much as possible. The area of section 70 is minimized to mitigate side leakage caused by wallboard grouting. [5] However, this kind of conventional structure type has found that the following problems still exist in the actual use experience: 1. Since some of the sections 70 not covered by the formwork 60 must be separated by a plurality of side by side wood strips 61, respectively Closed, resulting in a large increase in the workload of the formwork workers, of course, the personnel costs of construction have also increased. 2. Before the grouting, the formwork 60 is built. When the concrete is solidified, it is of course necessary to demolish the mold. The wood strip 61 built above must of course be removed, which will also increase the personnel cost and extend the working hours. 3. The aforementioned wooden strip 61 Usually, the wire is bundled, so compared with the large plate mold 60, it is relatively difficult to dismantle, and it is often necessary to be hardened with the help of the iron shovel to be removed, resulting in a large increase in the workload of the plate mold 60, in the same remuneration situation. Next, their willingness to work will be reduced. 4. It is well known that in the process of grouting, there is usually a procedure using mechanical vibration to guide the hole to avoid the occurrence of holes under the grout and affect the structural strength. However, in the process of vibration, if the aforementioned side-by-side wooden strips 61 are not fixed enough, resulting in external expansion, the wall panel after the demoulding is convex, it must be tapped slowly with a chisel, and then cemented with cement to cause manpower. waste. 5, as mentioned above, these wooden strips 61 can only reduce the side leakage phenomenon caused by wallboard grouting, so only the side leakage amount during wallboard grouting can be reduced, and the wallboard still needs to be removed after the formwork 60 is removed. Surface chiseling, although there are improvements in the construction method, it is only a reduction in the amount of chiseling. [6] The above-mentioned second concrete staircase and wall panel steel structure can effectively strengthen the structural strength and seismic strength of the stairs and wall panels. However, the construction cost is caused by the mold, the demoulding and the future chiseling work. The substantial increase has not only severely reduced the construction industry, but also increased the workload of the field employees. Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure with good structural strength and low construction cost is expected by users, and it is also necessary for relevant operators to strive to develop breakthrough goals and directions. [7] In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

[8] The main purpose of this creation is to provide a concrete structure for concrete stairs and wall panels. The technical problem to be solved is to improve the structural strength of the building by developing a new type that is more ideal and practical. The structural type with low construction cost is an innovative breakthrough for the goal. [9] The technical characteristics of this creation to solve the problem mainly lie in the "reinforcement structure of concrete stairs and wall panels", including: the wall panel reinforcement group standing on the support surface, and the one side overlapping the wall panel reinforcement group. a stair reinforcement group, wherein the stair reinforcement group forms an angle with the support surface; the wall panel reinforcement group includes a plurality of longitudinal reinforcements and transverse reinforcements that are mutually ligated to form a lattice-like structure; the staircase reinforcement group includes a plurality of mutual The longitudinal reinforcement and the transverse reinforcement are bundled to form a lattice-like structure; each transverse reinforcement of the staircase reinforcement group is vertically extended with a lap phase, and each lap section is combined with the wall panel reinforcement group; one or two The side systems are respectively tied to the metal mesh structure between the wall panel reinforcement group and the stair reinforcement group; when the wall panel is subjected to grouting operation, the gravel in the concrete will gradually block the mesh of the metal mesh structure, so that the wallboard is grouted The concrete does not flow into the stair reinforcement group. After the concrete in the wall panel mold is slightly solidified, the grouting operation of the stairs can be performed immediately. [10] With this innovative and unique design, this creation can eliminate the conventional chiseling operation, strengthen the structural strength between the stair and the wallboard, and shorten the working time of the grouting work, compared with the prior art. Achieve practical progress and better industrial economic benefits.

[12] Please refer to Figures 3, 4 and 5, "Concrete structure of concrete stairs and wall panels" includes a wall panel reinforcement group 10 standing on the support surface 40, and one side of the wall panel The stair reinforcing bar group 20 of the reinforcing bar group 10, wherein the stair reinforcing bar group 20 forms an angle θ with the supporting surface 40; the wall panel reinforcing bar group 10 includes a plurality of longitudinal reinforcing bars 11 and lateral reinforcing bars 12 which are mutually ligated to form a lattice shape. The structure of the stair steel bar 20 includes a plurality of longitudinal reinforcing bars 21 and transverse reinforcing bars 22 that are ligated to each other to form a lattice-like structure. Each of the transverse reinforcing bars 22 of the stair reinforcing bar group 20 is vertically extended with a lap phase 221, and each lap segment 221 is coupled with the wall panel reinforcing bar group 10. Before the wallboard grouting, it is necessary to build the formwork 60, which is no different from the conventional method. The biggest difference between this creation and the conventional steel structure is that the creation is in addition to the wallboard reinforcement group 10 and the stair reinforcement group 20. And further comprising at least one metal mesh structure 30, the metal mesh structure 30 is located in the formwork 60 and is blocked between the wall panel reinforcement group 10 and the stair reinforcement group 20, and is tied to the wall panel reinforcement group 10 and Between the stair reinforcing bars 20, in place of the aforementioned conventional wooden strips 61. The metal mesh structure 30 can be individually tied to the wall panel reinforcement group 10, or tied to the wall panel steel reinforcement group 10 and the stair reinforcement group 20, depending on the site construction conditions. The mesh size of the metal mesh structure 30 is limited to 5-8 mm. Its function and mesh specifications are limited. Please refer to it later. In a preferred embodiment of the present invention, a plurality of elongated metal mesh structures 30 are included, and each of the metal mesh structures 30 corresponds to a first-order staircase. [13] With the above structural composition design, the use case of this creation is described in detail as follows: As shown in Figures 4 and 5, the first set of the wallboard reinforcement group 10 and the stair reinforcement group 20 are constructed. After the formwork 60 is built, a metal mesh structure 30 is laid on the wall panel reinforcement group 10 and the stair reinforcement group 20, and the bottom edge of the metal mesh structure 30 extends in the direction of the stair reinforcement group 20. In this way, when the wallboard is subjected to grouting operation, since the mesh size of the metal mesh structure 30 is limited to 5-8 mm, the gravel in the concrete will gradually block all the meshes, so that the concrete will not flow when the wallboard is grouted. In the stair reinforcement group 20, after the concrete in the wall panel mold 60 is slightly solidified, the metal mesh structure 30 is wrapped in the solidified wall panel, and the stair portion can be grouted at this time. The foregoing grouting sequence is only used to illustrate the advantages and effects of the present creation, but it is not limited thereto. In actual construction, the grouting operation may be first performed on the stair portion. [14] Efficacy Description: The “reinforcing structure of concrete stairs and wall panels” disclosed in this work mainly replaces the conventional side-by-side wood strips by the above-mentioned metal mesh structure. Such a supply does have the following advantages: 1. The metal mesh structure can minimize the side leakage when the wallboard is grouted, so the chiseling procedure can be omitted; 2. The metal mesh structure is covered on the stairs after the grouting operation of the stair and the wall panel is completed. In the structure of the wall panel, the structural strength of the connection between the stairs and the wall panel can be effectively strengthened. 3, the use of metal mesh structure to replace the traditional wood strip, can avoid the operation of the wood strip form mold and demoulding, in addition to the more woven structural strength, but also can shorten the grouting operation time. 4. As mentioned above, in the process of grouting, the action of agitating (high-frequency vibration) concrete is usually used to avoid the coagulation to create a gap. Since the metal mesh structure is grouted in the wall, the concrete side leakage can be avoided. It can be stirred to improve the pounds (structural hardness) of the concrete after solidification, and it can reduce the cost and make the ladder back produce no honeycomb effect. Therefore, this creation is indeed a structure with both novelty and practical progress in comparison with the conventional structure proposed in [Prior Art]. [15] The structure disclosed in the above embodiments is used to specifically explain the present creation, and although the text is explained by specific terms, the scope of patents of the novel creation cannot be limited thereby; those who are familiar with the technical field can understand The spirit and principles of this creation are subject to change and modification to achieve an equivalent purpose, and such changes and modifications are to be included in the scope defined by the scope of the patent application as described later.
