Description

Technical Field

[0001] This utility model relates to a positioning mold, and more specifically, it relates to a positioning mold for a foundation pit pre-embedded plate. Background Technology

[0002] In recent years, with the advancement of national urban renewal projects, more and more old buildings are being retrofitted with elevators. Since most old buildings lack pre-installed concrete elevator shafts, steel structure elevator shafts need to be installed separately next to the building. These steel structure elevator shafts rely on their own load-bearing capacity, without burdening the original building's support. Before constructing such steel structure elevator shafts, a foundation pit matching the designed shaft needs to be pre-set, and multiple embedded plates need to be installed around the foundation pit according to the shaft's dimensions. If the installation position of the embedded plates deviates, it will affect the subsequent construction of the columns, thus affecting the stability of the steel structure elevator shaft installation. Currently, there are no dedicated molds for positioning the embedded plates in the foundation pit of steel structure elevator shafts. Usually, simple positioning plates are used on-site to estimate the installation position of the embedded plates, making the installation position prone to deviation and lacking consistency across different construction sites. Therefore, it is necessary to further research and improve the structure of the aforementioned embedded plate positioning molds. Utility Model Content

[0003] One of the purposes of this utility model is to address the above-mentioned shortcomings by providing a positioning mold for a foundation pit embedded plate, in order to solve the technical problems such as the easy deviation of the positioning of the embedded plate by the simple positioning plate in the prior art and the lack of consistency in positioning at different construction sites.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The present invention provides a positioning mold for a foundation pit embedded plate, comprising a first positioning beam and a second positioning beam, the first positioning beam and the second positioning beam overlapping each other; both ends of the second positioning beam are provided with pad beams, the pad beams overlapping the ends of the second positioning beams vertically, the thickness of the pad beams being slightly equal to the thickness of the first positioning beams; both ends of the first positioning beams are used to fix the embedded plate to complete the positioning.

[0006] As a preferred further technical solution, the two end plates of the first positioning beam are fixed to the embedded plate by tapered sleeves, and the embedded plate is provided with bolts.

[0007] A further technical solution is that: on both sides of the overlapping part of the first positioning beam and the second positioning beam, limit blocks are fixed, and the gap between the two limit blocks is slightly equal to the width of the second positioning beam.

[0008] A further technical solution is that the first positioning beam and the second positioning beam are perpendicular to each other.

[0009] A further technical solution is that there are four embedded plates arranged in a rectangular array, and the distance between two adjacent embedded plates and the distance between two diagonally opposite embedded plates are all equal.

[0010] Compared with the prior art, one of the beneficial effects of this utility model is that by setting the first positioning beam and the second positioning beam diagonally according to the embedded plate, the rectangular positioning of the four embedded plates is completed, and then the bolt position of the column installation is positioned by the embedded plate. Since the length of the first positioning beam and the second positioning beam is fixed, the accuracy of the embedded plate installation position and the consistency of the embedded plate bolt positioning at different construction sites can be guaranteed. At the same time, the foundation pit embedded plate positioning mold provided by this utility model has a simple structure and can be applied to the bolt positioning of steel structure elevator shaft columns of various specifications, with a wide range of applications.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] refer to Figure 1 As shown, one embodiment of this utility model is a positioning mold for a foundation pit embedded plate, which includes a first positioning beam 1 and a second positioning beam 2, the aforementioned first positioning beam 1 and second positioning beam 2 overlapping and intersecting each other; combined with Figure 2As shown, each end of the aforementioned second positioning beam 2 is provided with a pad beam 3. The pad beam 3 overlaps vertically with the ends of the second positioning beam 2, and the thickness of the pad beam 3 is slightly equal to the thickness of the first positioning beam 1. In the installation method shown in the figure, the total length of the second positioning beam 2 and the two pad beams 3 is equal to the length of the aforementioned first positioning beam 1, and the second positioning beam 2 and the two pad beams 3 form a whole to cooperate with the first positioning beam 1 to form a cross shape. Thus, the two pad beams 3 at both ends of the first positioning beam 1 can be fixed to the pre-embedded plates 4 at the diagonal corners of the steel structure elevator shaft to complete the positioning. Since the lengths of the aforementioned second positioning beam 2, pad beams 3, and first positioning beam 1 are equal, when they intersect, the corresponding four positions form a rectangular array. Installing the pre-embedded plates 4 at the ends of both can ensure the accuracy of the positioning.

[0017] Preferably, the two ends of the first positioning beam 1 and the two pad beams 3 can be temporarily fixed to the embedded plate 4 using a tapered sleeve 5 to complete the positioning. At the same time, the embedded plate 4 is provided with multiple bolts, the positions of which correspond perfectly with the positions of the bolts and bolt holes at the bottom of the steel structure elevator shaft column.

[0018] Simultaneously, the first positioning beam 1 and the second positioning beam 2 can be perpendicularly intersecting each other as shown in the figure. This achieves... Figure 1 The four embedded plates 4 shown are arranged in a rectangular array, and the distance between two adjacent embedded plates 4 and the distance between two diagonally opposite embedded plates 4 are equal. On the other hand, the intersection angle between the first positioning beam 1 and the second positioning beam 2 can be adjusted adaptively according to the different length-to-width ratios of the shaft. For example, when the shape of the foundation pit is rectangular, the first positioning beam 1 and the second positioning beam 2 do not intersect perpendicularly, and the angles of their two adjacent corners are different.

[0019] In this embodiment, by setting the first positioning beam 1 and the second positioning beam 2 diagonally according to the embedded plate 4, the rectangular positioning of the four embedded plates 4 is completed, and then the bolt position of the column installation is positioned by the embedded plates 4. Since the lengths of the first positioning beam 1 and the second positioning beam 2 are fixed, the accuracy of the installation position of the embedded plate 4 and the consistency of the embedded plate bolt positioning at different construction sites can be guaranteed.

[0020] Combination Figure 3As shown, according to another embodiment of the present invention, to further improve the positioning accuracy, a limiting block 6 can be fixed on each side of the overlapping portion of the first positioning beam 1 and the second positioning beam 2, and the gap between the two limiting blocks 6 is slightly equal to the width of the second positioning beam 2, so that the second positioning beam 2 can be locked in the gap between the aforementioned limiting blocks 6. Furthermore, the gap between the aforementioned limiting blocks 6 needs to be set at the middle position of the first positioning beam 1. Preferably, in this embodiment, the limiting blocks 6 can be directly welded to the first positioning beam 1; similarly, the aforementioned pad beam 3 can also be welded to the lower part of both ends of the second positioning beam 2.

[0021] refer to Figures 1 to 3 As shown, in actual use, in a preferred embodiment of this utility model, after setting the location of the steel structure elevator shaft pit, a first positioning beam 1 is installed at the diagonal position of the pit. Then, a second positioning beam 2 is installed on top of the first positioning beam 1. The second positioning beam 2 is placed in the gap between the two limiting blocks 6, and the first positioning beam 1 and the second positioning beam 2 form a cross shape perpendicular to each other. At this time, the positions of the two ends of the first positioning beam 1 and the ends of the two pad beams 3 are the accurate positions of the four embedded plates 4. After determining the positions, the two ends of the first positioning beam 1 and the ends of the two pad beams 3 can be temporarily fixed to their respective embedded plates 4 using conical sleeves. Then, the embedded plates 4 can be installed in the corresponding positions. After the embedded plates 4 are installed, the bolt positions for the column installation can be completed, and the final form is as follows. Figure 1 As shown, after the four embedded plates 4 are installed, the positioning mold is removed as a whole, and then the embedded plates 4 are removed. At this time, the columns of the steel structure elevator shaft can be installed through the determined bolt positions. The lower end of the column is pre-welded with an embedded plate that is exactly the same as the aforementioned embedded plate 4 in terms of structure, size and bolt position.
