Description

Technical Field

[0001] This invention relates to the field of building construction technology, and specifically to a method for constructing concrete stairs. Background Technology

[0002] In recent years, more and more buildings in China have adopted fair-faced concrete as their finish. With increasingly sophisticated construction techniques, designers are demanding higher standards for the aesthetic appeal of fair-faced concrete. Outdoor staircases, as part of a building, are inherently complex, making it difficult to control the quality of their construction. Currently, the staircase structure and side panels are typically poured together to ensure structural stability. However, due to the complexity and size of the staircase, incomplete pouring can occur, resulting in an unsightly structure. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a concrete staircase construction method. In the construction process, the side plates of the staircase are poured first, and threaded sleeves are set in the side plates of the staircase to facilitate the subsequent installation of connecting bars. By inserting the connecting bars into the two oppositely arranged side plates of the staircase, positioning and support are provided for the subsequent pouring of the stair slab.

[0004] A concrete staircase construction method to achieve the above objectives includes the following steps:

[0005] The construction location of the side slab of the building section is determined in the construction area. Reinforcing bars are tied in the construction location of the side slab of the building section to form a reinforcing bar frame. Two reinforcing bar frames are set up and placed opposite each other.

[0006] The position of the ladder plate is determined on the steel reinforcement frame, and the threaded sleeve is fixed on the steel reinforcement frame;

[0007] A side panel casting template is provided, which is set at the construction position of the side panel of the building section. The side panel casting template has an opening corresponding to the position of the threaded sleeve.

[0008] Provide connecting bars, and insert the connecting bars into the threaded sleeves of two oppositely arranged steel bar frames;

[0009] Concrete is poured into the side plate casting formwork, and the side plate casting formwork is removed after the concrete reaches the demolition strength.

[0010] A stair slab casting template is provided, which is set on the outside of the connecting reinforcement bar, and concrete is poured into the stair slab casting template to form a stair structure.

[0011] Furthermore, when the connecting rib is inserted into the threaded sleeve, a rubber stopper is filled between the connecting rib and the threaded sleeve.

[0012] Furthermore, after the concrete inside the side plate casting template reaches the required strength for removal, the rubber stopper is removed.

[0013] Furthermore, when locating the position of the stair slab, a positioning line is provided, and the positioning line is set on the steel reinforcement frame corresponding to the position of the stair slab.

[0014] Furthermore, before setting the stair slab casting template on the outside of the connecting bar, the stair section reinforcement cage is tied to the connecting bar.

[0015] Furthermore, after the staircase structure is poured, stone is laid on the surface of the staircase structure.

[0016] Furthermore, multiple threaded sleeves are provided, and when fixing the threaded sleeves on the steel reinforcement frame, the threaded sleeves are arranged according to the on-site construction requirements.

[0017] Furthermore, the end of the threaded sleeve is provided with an anchoring bar, which is fixed to the steel reinforcement frame when the threaded sleeve is fixed.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] During construction, the side slabs of the floor section are poured first, and threaded sleeves are installed inside the side slabs to facilitate the subsequent installation of connecting bars. By inserting the connecting bars into the two opposite side slabs of the floor section, positioning and support are provided for the subsequent pouring of the stair slab. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1A method for constructing a concrete staircase includes the following steps: determining the construction position of the side slab 1 of the staircase in the construction area; binding reinforcing bars to form a reinforcing bar frame within the construction position of the side slab 1; setting two reinforcing bar frames opposite to each other; determining the position of the stair slab on the reinforcing bar frame; fixing threaded sleeves on the reinforcing bar frame; providing a side slab casting template; setting the side slab casting template at the construction position of the side slab 1; the side slab casting template having openings corresponding to the positions of the threaded sleeves; providing connecting bars 3; inserting the connecting bars 3 into the threaded sleeves of the two oppositely set reinforcing bar frames; pouring concrete into the side slab casting template; removing the side slab casting template after the concrete reaches the demolition strength; providing a stair slab 2 casting template; setting the stair slab 2 casting template outside the connecting bars 3; and pouring concrete into the stair slab 2 casting template to form a staircase structure.

[0026] In this invention, a preferred embodiment is as follows: When constructing the staircase, the side panels 1 on both sides of the stair section are constructed first. The tied steel reinforcement frame is placed at the construction position of the side panel 1. The edge line of the stair section slab is positioned on the steel reinforcement frame. Then, according to the structural drawings of the stair section slab, straight threaded sleeves are embedded (standard A16 sleeves can be used; generally, the diameter of the steel reinforcement in the stair section slab is less than 16mm, and the diameter can be increased and the spacing appropriately widened in consultation with the design unit). Subsequently, the formwork for the side panels (or side beams) of the stair section is constructed. The support is installed by setting a connecting rib 3 inside the straight threaded sleeve. When setting the connecting rib 3, one end of the connecting rib 3 is inserted into the threaded sleeve on one side, and the other end is placed in the threaded sleeve on the other side and sealed with a rubber plug. When the straight threaded sleeve is embedded, measures should be taken to fix it firmly to prevent disturbance and displacement during the pouring of the floor section side plate 1. Concrete is then poured into the floor section side plate 1. After the stair section side plate reaches the demolding strength, the formwork is removed, the rubber plug in the straight threaded sleeve is unscrewed, and the subsequent stair section slab construction is carried out.

[0027] Furthermore, when the connecting rib 3 is inserted into the threaded sleeve, a rubber stopper is filled between the connecting rib 3 and the threaded sleeve. By filling the gap between the connecting rib 3 and the threaded sleeve with a rubber stopper, the connecting rib 3 is prevented from shaking during the pouring of the side slab 1 of the building section, thus avoiding any deviation in the position of the threaded sleeve.

[0028] Furthermore, after the concrete inside the side plate casting template reaches the required strength for removal, the rubber stopper is removed.

[0029] Furthermore, when positioning the stair slab, a positioning line is provided, which is set on the steel reinforcement frame corresponding to the position of the stair slab 2. This positioning line facilitates the subsequent installation of the threaded sleeve. After the threaded sleeve is installed, the positioning line can be removed to avoid affecting the next stage of construction.

[0030] Furthermore, before setting the stair slab 2 casting template on the outside of the connecting bar 3, the stair section reinforcement cage is tied to the connecting bar 3.

[0031] Furthermore, after the staircase structure is poured, stone is laid on the surface of the staircase structure.

[0032] Furthermore, multiple threaded sleeves are provided, and when fixing the threaded sleeves on the steel reinforcement frame, the threaded sleeves are arranged according to the on-site construction requirements.

[0033] Furthermore, the end of the threaded sleeve is provided with an anchoring bar 4, which is fixed to the steel reinforcement frame when the threaded sleeve is fixed.

[0034] The following describes the process of using a concrete staircase construction method according to the present invention.

[0035] When constructing the staircase, prioritize the construction of the side panels 1 on both sides of the staircase. Place the tied steel reinforcement frame at the construction position of the side panel 1, and position the edge line of the staircase slab on the steel reinforcement frame. Then, embed straight threaded sleeves according to the structural drawings of the staircase slab (standard A16 sleeves can be used; generally, the diameter of the staircase slab reinforcement is less than 16mm, and the diameter can be increased by communicating with the design unit, and the spacing can be appropriately widened at the same time). Subsequently, erect the formwork for the side panel (or side beam) of the staircase. Set the connecting bar 3 inside the straight threaded sleeve. When setting the connecting bar 3, one end of the connecting bar 3 is inserted into the threaded sleeve on one side, and the other end is placed in the threaded sleeve on the other side and sealed with a rubber plug. When embedding the straight threaded sleeve, measures should be taken to fix it firmly to prevent disturbance and displacement during the pouring of the side panel 1. Pour concrete for the side panel 1. After the side panel reaches the demolding strength, remove the formwork, unscrew the rubber plug in the straight threaded sleeve, and proceed with the subsequent construction of the staircase slab.

[0036] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
