[0030] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by the terms "top", "bottom", "inside", "outside", "circumferential", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] like Figures 1 to 4 As shown, a building construction structure of the present invention comprises a bottom form 2, an inflatable pad 3, a concrete pad and a main structure steel bar 6, wherein the main structure steel bar 6 is supported and arranged on the top of the bottom form 2 through the concrete pad, the inflatable pad 3 is arranged between the main structure steel bar 6 and the bottom form 2, the inflatable pad 3 can adjust its own height by inflating and deflating, the top surface of the bottom form 2 comprises an adjacent poured area 5 and an unpoured area 7, the poured area 5 is poured with concrete, and the inflatable pad 3 is arranged in the unpoured area A cleaning hole 8 is opened on the uncast area 7 of the bottom form 2, and a closed formwork 4 is movably arranged on the uncast area 7 of the bottom form 2. The closed formwork 4 is located between the bottom form 2 and the main structure steel bars 6. The outer peripheral contour of the closed formwork 4 is matched with the cleaning hole 8, and the thickness of the closed formwork 4 is equal to the thickness of the bottom form 2. The closed formwork 4 can slide along the uncast area 7 to push the garbage to the cleaning hole 8, and move into the cleaning hole 8 to cover the cleaning hole 8.

[0034] Based on the above technical scheme, the main structural steel bars are composed of a plurality of steel bars that are staggered and fixedly connected with each other; the outer contour of the closed formwork 4 is adapted to the cleaning opening 8, which means that the outer contour of the closed formwork 4 is the same as the outer contour of the cleaning opening, but the outer dimensions of the closed formwork 4 are smaller than the outer dimensions of the cleaning opening 8 to facilitate the closed formwork 4 to cover the cleaning opening 8, and the concrete overflowing and formed from the covering gap can be directly scraped off in post-processing. If the closed formwork 4 and the cleaning opening 8 are designed with the same size contour as the standard, the closed formwork 4 may be difficult to cover the cleaning opening 8 due to errors; the equal thickness of the closed formwork 4 and the bottom formwork 2 is to prevent the formed floor slab or beam from bulging or sinking; the closed formwork 4 can be manufactured using the blanking of the cleaning opening 8; the unfinished concrete of the bottom formwork 2 A closed formwork 4 is movably arranged on the pouring area 7, which means that one side of the closed formwork 4 is attached to the unpoured area 7 of the bottom formwork 2, and the closed formwork 4 can slide along the unpoured area 7 of the bottom formwork 2; the concrete pad is used to support and raise the main structure steel bars 6 to a specified height, and then pouring is carried out; due to design requirements, the concrete pad is not necessarily thicker or thinner than the closed module, and the concrete pad is an arbitrarily selected pad, and the thickness of the concrete pads varies, and it cannot be guaranteed that the gap between the bottom of the main structure steel bars 6 and the bottom formwork 2 at any point is larger than the thickness of the closed formwork 4, so it is necessary to set an inflatable pad 3 to support the main structure steel bars 6 to ensure that the closed formwork 4 has sufficient movable space; the adjustable maximum thickness of the inflatable pad 3 is thicker than the closed formwork, and the adjustable maximum thickness of the inflatable pad 3 is thicker than the concrete pad.

[0035] Furthermore, it also includes a support member 1, which is arranged under the bottom mold 2 to support the bottom mold 2, and the closed mold 4 is fixedly connected to the support member 1 to cover the cleaning hole 8.

[0036] The support member 1 includes secondary ribs, primary and secondary ribs and a support frame. The secondary ribs are arranged at intervals below the bottom mold 2 to support the bottom mold 2. The primary and secondary ribs are arranged at intervals below the secondary ribs to support the secondary ribs. The support frame supports the primary and secondary ribs.

[0037] Furthermore, the cleaning opening 8 is opened near the poured area 5 and extends along the boundary line between the poured area 5 and the uncast area 7 .

[0038] The poured area 5 and the uncast area 7 are generally rectangular, the side lines of the poured area 5 and the uncast area 7 are straight lines, the cleaning opening 8 extends along the boundary line direction of the poured area 5 and the uncast area 7, and the cleaning opening 8 is arranged in a long strip along the boundary line direction of the poured area 5 and the uncast area 7, and the long side of the long strip is parallel to the boundary line direction of the poured area 5 and the uncast area 7.

[0039] Furthermore, when the closed template 4 is disposed at the cleaning opening 8, the maximum gap between the closed template 4 and the cleaning opening 8 is less than 2 mm.

[0040] When pouring concrete, concrete will seep down along the gap between the closed template 4 and the cleaning hole 8. The larger the gap between the closed template 4 and the cleaning hole 8, the deeper the depth of concrete penetration and the wider the cross section, and the more troublesome the subsequent treatment. The maximum outline size of the closed template 4 and the cleaning hole 8 should not be too large, and less than 2mm is the gap standard for the pouring template.

[0041] Furthermore, the closed template 4 includes a plurality of template units.

[0042] The boundary line between the poured area 5 and the unpoured area 7 is relatively long, and the lengths of the cleaning opening 8 and the closed formwork 4 will also be adjusted according to the length of the boundary line to improve the convenience of discarding garbage when cleaning each construction joint. The longer the closed formwork 4 is, the heavier the weight of the closed formwork 4 is, and the more difficult it will be to drag the closed formwork 4. Dividing the closed formwork 4 into multiple formwork units can reduce the difficulty of dragging the closed formwork 4.

[0043] When the closed formwork 4 is composed of a plurality of formwork units, when the closed formwork 4 is covered on the cleaning opening 8, the formwork units can be spread out separately so that the formwork units have gaps while reducing the gap between the closed formwork 4 and the cleaning opening 8, which is equivalent to dividing the large gap into more small gaps, reducing the penetration depth of the concrete, and reducing the difficulty of post-processing of the poured concrete.

[0044] Furthermore, the inflatable cushion blocks 3 are provided on both sides of the closed template 4, which can ensure that the closed template 4 can slide arbitrarily within the range of movement. At this time, the inflatable cushion blocks 3 simultaneously support the main structural steel bars 6 on at least two sides of the closed bottom mold 2. The inflatable cushion blocks 3 only need to be inflated to a thickness slightly larger than the closed template 4.

[0045] When the inflatable cushion block 3 is set on one side of the closed formwork 4, the inflatable cushion block 3 should be thick enough that the vertical height of the movable range of the closed formwork 4 farthest from the inflatable cushion block 3 (here refers to the distance between the main structure steel bars 6 and the bottom formwork 2) is greater than the thickness of the closed formwork 4, so that the closed formwork 4 can move freely within its movable range. Since the inflatable cushion block 3 only supports one side, the upward movement of the main structure steel bars 6 caused by the inflatable cushion block 3 decreases with the increase of the distance from the inflatable cushion block 3, which results in the required thickness of the inflatable cushion block 3 being very large.

[0046] Furthermore, a garbage container and a funnel are provided below the cleaning hole 8, and the funnel is installed on the top of the garbage container. The upper opening of the funnel is larger than the lower opening. The upper opening of the funnel is facing the cleaning hole 8, and the size contour of the upper opening is not less than the contour size of the cleaning hole 8.

[0047] Since the present invention is a construction structure of a floor slab or a beam, a garbage container and a hopper can be arranged on a lower floor to facilitate direct collection of discarded garbage.

[0048] Furthermore, the inflatable cushion block 3 is in the shape of a long rectangular block.

[0049] The inflatable cushion block 3 in the shape of a long rectangular block is advantageous in that the inflatable cushion block 3 can span across and be placed under multiple main structure steel bars, and after being deflated, it is also relatively easy to take out due to its slender shape.

[0050] This embodiment also involves a construction method:

[0051] The bottom form 2 is divided into a poured area 5 and an unpoured area 7, the poured area 5 and the unpoured area 7 are adjacent to each other, the bottom form 2 is provided with a cleaning opening 8 in the unpoured area 7, the bottom form 2 is arranged on the support 1 and fixedly connected, a concrete pad is placed on the bottom form 2, a closed form 4 is placed on the unpoured area 7, a main structure steel bar 6 is arranged on the top of the bottom form 2 and supported by the concrete pad, and concrete is poured in the poured area 5;

[0055] After the closed formwork 4 is dragged to the sealing cleaning opening 8 and the garbage on the dragging track is swept into the cleaning opening 8, before the uncast area 7 is cast with concrete, the inflatable cushion block 3 is deflated and the inflatable cushion block 3 is pulled out.

[0056] Further, the closed template 4 includes a plurality of template units, and the dragging of the closed template 4 to sweep the garbage on the dragging track into the cleaning hole 8 includes:

[0057] Drag each of the template units separately to scatter the garbage on the dragging track of each template unit into the cleaning hole 8;

[0058] The step of moving the closing template 4 to the cleaning hole 8 to cover the cleaning hole 8 and fixing the closing template 4 to the support member 1 includes:

[0059] Each template unit is laid separately on the support member 1 to cover and clean the hole 8, and each template unit is fixedly connected to the support member 1.

[0060] Furthermore, the specific connection methods of fixed setting and fixed connection refer to the relative position relationship of two components that can be fixedly connected, including fixing by connecting parts, fixing by welding, fixing by adhesives, fixing by integral molding, and fixing by snap connections.

[0061] Furthermore, the connecting parts include fasteners, straps, ties, pneumatic connecting elements, hydraulic connecting elements, flange plates, Velcro, and buttons.
