Description

Technical Field

[0001] The utility model relates to the field of stairs, in particular to a horizontal mold for prefabricated hollow stairs. Background Art

[0002] The current prefabricated stairs are usually solid plate stairs, which have a particularly large deadweight. During transportation, they are often limited by the lifting capacity of the tower crane and cannot be hoisted. Therefore, in the process of house construction, hollow stairs are increasingly used.

[0003] Traditional hollow staircases usually have through-holes for reducing weight at the step positions, which can reduce the weight of the stairs while ensuring the structural strength of the stairs, making it easier to hoist and install the stairs.

[0004] In the traditional production process of hollow staircases, foam columns are usually placed in the staircase mold and weight-reducing holes are formed after pouring.

[0005] However, due to the light weight of the foam column, it is easy for the foam column to be dislocated or deformed during the concrete pouring and vibration process, making the formed weight-reducing holes irregular, which will seriously affect the structural strength of the stairs and needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 , Figure 2 As shown, a horizontal mold for a prefabricated hollow staircase includes a support frame 1, a bottom plate 2, a side plate 3 and an end plate 4. The support frame 1 is arranged on the ground, the bottom plate 2 is arranged on the support frame 1, and the interior is arranged in a stepped shape to form the steps of the staircase.

[0030] like Figure 1 , Figure 2 As shown, the side panels 3 are vertically arranged on both sides of the bottom plate 2, the end panels 4 are arranged at both ends of the bottom plate 2 and are located between the side panels 3, the bottom plate 2, the side panels 3 and the end panels 4 are fixed to each other to form a cavity for concrete pouring, and the shape of the cavity is the same as the shape of the stairs.

[0031] like Figure 1 , Figure 2 As shown, the upper end of each side panel 3 is vertical and has multiple tie rods 31 arranged at intervals, and an anchor bolt 32 is arranged between a pair of tie rods 31 in opposite positions to achieve the tightening and fixing of the pair of side panels 3 to prevent the side panels 3 from deforming during concrete pouring, thereby ensuring high-precision molding of the stairs.

[0032] like Figure 2 , Figure 3 As shown, a plurality of sliding holes 33 are horizontally penetrated through the outer wall of each side panel 3, and each sliding hole 33 is aligned with the steps of the formed staircase.

[0033] like Figure 2 , Figure 3 As shown, the outer wall of each side plate 3 is provided with a plurality of support plates 5 corresponding to the sliding holes 33 , and long hole piles 51 and short hole piles 52 are respectively provided on both sides of the support plates 5 , and the long hole piles 51 and the short hole piles 52 are both used for drilling the sliding holes 33 .

[0034] like Figure 2 , Figure 3 As shown, the long bored pile 51 and the short bored pile 52 are both hollow, so as to reduce the deadweight of the long bored pile 51 and the short bored pile 52, making the sliding process of the two more convenient. At the same time, the long bored pile 51 and the short bored pile 52 are both provided with a reinforcing frame 53 inside to increase the structural strength of the two, avoid deformation, and ensure the stable production and processing of the hollow staircase and the solid staircase.

[0035] like Figure 2 , Figure 3 As shown, the long bored pile 51 and the short bored pile 52 have an arc-shaped chamfer 54 at one end away from the support plate 5, so as to enable the long bored pile 51 and the short bored pile 52 to slide smoothly into the sliding hole 33 to prevent jamming.

[0036] like Figure 2 , Figure 3 As shown, when the long bored pile 51 penetrates the sliding hole 33, the pair of long bored piles 51 in opposite positions collide with each other, so as to form through-holes for weight reduction on the steps of the formed staircase, which is used for manufacturing and processing the hollow staircase. When the short bored pile 52 penetrates the sliding hole 33, the inner ends of the pair of short bored piles 52 in opposite positions are flush with the inner side wall of the side plate 3, so as to completely block the sliding hole 33, which is used for manufacturing and processing the solid staircase.

[0037] like Figure 3 , Figure 4 As shown, support rods 6 are horizontally connected between multiple support plates 5, and slide rails 7 are horizontally arranged at both ends of the side plates 3. Both ends of the support rods 6 pass through the slide rails 7 and are provided with rollers 61 that cooperate with the slide rails 7. At the same time, hand wheels 62 are provided at both ends of the support rods 6, so that all the support plates 5 can drive the long bored piles 51 and the short bored piles 52 to slide horizontally.

[0038] like Figure 3 , Figure 4 As shown, flat guide blocks 63 are provided at both ends of the support rod 6, and a guide track 71 is provided on the slide rail 7 along its length direction for the guide block 63 to slide, and a circular track 72 is provided at the tail end of the guide track 71 that is connected to the guide track 71 and for the guide block 63 to rotate.

[0039] like Figure 3 , Figure 4 As shown, a locking mechanism 8 for fixing the support rod 6 is provided on the side plate 3, and the locking mechanism 8 includes a locking rod 81 and a pull ring 82. The locking rod 81 is vertically slidably connected to the side plate 3, and a locking hole 83 for the locking rod 81 to pass through is provided on the guide block 63. The pull ring 82 is provided at the upper end of the locking rod 81 and is used to control the vertical movement of the locking rod 81.

[0040] When producing hollow stairs, first pull the locking rod 81 upward to disengage the locking rod 81 from the locking hole 83, thereby releasing the lock of the guide block 63, and then control the hand wheel 62 to drive the support rod 6, the support plate 5, the long bored pile 51 and the short bored pile 52 to slide backward. At this time, the guide block 63 slides in the guide rail 7 to achieve stable sliding control of the long bored pile 51 and the short bored pile 52.

[0041] When the guide block 63 moves into the annular track 72, the hand wheel 62 can be controlled to drive the support rod 6, the support plate 5, the long hole pile 51 and the short hole pile 52 to rotate synchronously until the long hole pile 51 faces the sliding hole 33. The hand wheel 62 is controlled to drive the support rod 6, the support plate 5, the long hole pile 51 and the short hole pile 52 to slide forward synchronously. At this time, the guide block 63 is re-embedded in the guide track 71, so that the long hole pile 51 can slide forward stably.

[0042] Until the grown hole pile 51 passes through the sliding hole 33, the pair of grown hole piles 51 in opposite positions will abut against each other, and the support plate 5 will abut against the outer wall of the side plate 3. Then the locking rod 81 is controlled to move downward and plug into the locking hole 83, so that the support plate 5 and the grown hole pile 51 can be fixed.

[0043] Finally, a steel cage is arranged in the cavity, and then concrete is poured, and the concrete is vibrated and smoothed, and then the concrete is completely solidified. Finally, the previous steps are repeated to control the long hole pile 51 to move outward, so that a through weight-reducing hole is formed on the formed staircase, and then the staircase is taken out, and the production and processing of the hollow staircase can be realized.

[0044] When producing solid stairs, repeat the previous steps to make the short bored pile 52 face the sliding hole 33, until the short bored pile 52 is inserted into the sliding hole 33, the pair of short bored piles 52 in opposite positions both block the sliding hole 33, and then control the locking rod 81 to move downward and insert into the locking hole 83, so as to achieve the fixation of the support plate 5 and the short bored pile 52.

[0045] Finally, a steel cage is placed in the cavity, and then concrete is poured, vibrated and smoothed, and the concrete is completely solidified. Finally, the stairs are directly taken out to realize the production and processing of solid stairs.

[0046] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
