Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a mold system for arc-shaped reinforced concrete beams. Background Art

[0002] During the construction of the main structure, the arc beams are formed as follows: 1. For beams with larger arcs, the arcs are progressively bent along the length direction with large templates according to the arc of the structural construction drawing, and then reinforced with steel pipes or steel bars, screws, square timbers and support frames. 2. For beams with smaller arcs, the entire beam is divided into multiple small templates of different sizes for assembly according to the arc of the structural construction drawing, and then reinforced with steel pipes or steel bars, screws, square timbers and support frames. This process is a common construction process on the market and can meet the design requirements. However, the arc measurement and positioning, and the reinforcement of the beam side templates are difficult, which affects the progress. In addition, materials are easily consumed during the production process, a large amount of sawdust is generated, which pollutes the environment and reduces work efficiency. It is also impossible to guarantee the naturalness of the lines of the arc beams after the concrete is poured and formed, and there are major quality risks. Summary of the invention

[0003] The utility model aims to provide a mold system for arc-shaped reinforced concrete beams, which can realize standardized operation, reduce production costs and improve construction efficiency.

[0004] The utility model is realized by the following technical scheme: a mold system for arc-shaped reinforced concrete beams, comprising

[0005] The lifting support rod is a sleeve rod structure placed on the ground and capable of adjusting the height;

[0006] The angle adjustment member is rotatably connected to the top of the lifting support rod and can be swung left and right and locked to achieve angle adjustment;

[0007] The arc-shaped mold is disassembled and connected with the top of the angle adjustment member, and is a mold consistent with the curvature of the arc-shaped reinforced concrete beam;

[0008] Several lifting rods with arc-shaped molds are arranged from left to right between two adjacent columns, and the angles of any two adjacent arc-shaped molds are adjusted until the two arc-shaped molds are sealed and fitted;

[0009] Wherein, the arc-shaped mold comprises a front arc-shaped plate, a rear arc-shaped plate and an arc-shaped bottom plate, and the front arc-shaped plate and the rear arc-shaped plate are respectively connected to the front and rear edges of the arc-shaped bottom plate to form a mold with a U-shaped cross section;

[0010] Limiting structures are provided on the outer sides of the front arc plate and the rear arc plate; a locking mechanism connected to the limiting structure is provided between any two adjacent arc molds for tightly fitting the two arc molds.

[0011] Compared with the previous technology, the beneficial effects of the utility model are:

[0012] 1. The lifting rod and arc mold are designed to be separated. The arc mold can be customized according to needs and installed on the lifting rod, which is convenient for transportation and reduces costs.

[0013] 2. Except for a small number of non-standard arc molds and end arc molds, other standard arc molds can be laid out in a unified manner, and the mold cost expenditure of the project is low. Even in the same project, standard arc molds and end arc molds can be used repeatedly, further reducing mold cost expenditure.

[0014] 3. The angle adjustment parts can be initially positioned, which is convenient for workers to assemble quickly. However, due to the limited limiting capacity of the angle adjustment parts, the reliability of the connection between adjacent arc templates can be guaranteed through the rear locking mechanism to avoid the displacement of the arc template during the casting process and cause leakage.

DETAILED DESCRIPTION

[0023] The utility model is described in detail below in conjunction with the accompanying drawings:

[0024] like Figure 1-6 Shown: A mold system for curved reinforced concrete beams, comprising

[0025] The lifting support rod 1 is a sleeve rod structure placed on the ground and capable of adjusting the height;

[0026] An angle adjustment member 2 is rotatably connected to the top of the lifting support rod 1 and can be swung left and right and locked to achieve angle adjustment;

[0027] The arc-shaped mold 3 is detachably connected to the top of the angle adjustment member 2 and is a mold consistent with the curvature of the arc-shaped reinforced concrete beam;

[0028] A plurality of lifting rods 1 with arc-shaped molds 3 are arranged from left to right between two adjacent columns 9, and the angles of any two adjacent arc-shaped molds 3 are adjusted until the two arc-shaped molds 3 are sealed and fitted;

[0029] The arc mold 3 includes a front arc plate 31, a rear arc plate 32 and an arc bottom plate 33, wherein the front arc plate 31 and the rear arc plate 32 are respectively connected to the front and rear edges of the arc bottom plate 33 to form a mold with a U-shaped cross section;

[0030] Limiting structures are provided on the outer sides of the front arc plate 31 and the rear arc plate 32 ; a locking mechanism connected to the limiting structure is provided between any two adjacent arc molds 3 for tightly fitting the two arc molds 3 .

[0031] Since the heights of various positions in the arc reinforced concrete beam are different, the lifting support rod 1 is required to adjust the height of the arc mold 3. Accordingly, since the angles of the arc mold 3 corresponding to the various nodes of the arc reinforced concrete beam are different, in order to meet the adaptability of the arc mold 3, an angle adjustment member 2 is set between the arc mold 3 and the lifting support rod 1. Since the angle adjustment member 2 needs to be set to facilitate the adjustment of the angle, the locking ability is insufficient. If concrete is poured on the arc mold 3 at a later stage, the angle of part of the arc mold 3 may change, resulting in leakage. For this reason, a locking mechanism is set to ensure the connection strength between any two adjacent arc molds 3.

[0032] like Figure 4 As shown: the aforementioned limiting structure is a limiting rod 34 disposed on the left and right sides of the front arc plate 31 and the rear arc plate 32, and more than two groups of limiting rods 34 are disposed on the left or right sides;

[0033] The locking mechanism includes a basket-shaped tie rod 41, and both ends of the basket-shaped tie rod 41 are provided with limit rings 42. By adjusting the basket-shaped tie rod 41, the connection strength between any two adjacent arc-shaped molds 3 can be ensured.

[0034] like Figure 6As shown: the main body of the angle adjustment member 2 is a limiting column 21, a locking ring 22 is provided at the bottom of the limiting column 21, a locking nut 23 is provided at the top of the lifting support rod 1, and the locking ring 22 is installed on the locking nut 23 through a locking bolt 24.

[0035] Here is a simple nut locking structure, by rotating the locking bolt 24, the locking ring 22 is pressed against the locking nut 23 or the locking ring 22 is separated from the locking nut 23. Thus, the limit column 21 is swung left and right and locked.

[0036] The bottom surface of the arc bottom plate 33 is provided with a limiting tube 25, and the limiting tube 25 is inserted into the limiting column 21. This is to facilitate the insertion with the limiting column 21 and realize quick connection and separation.

[0037] The arc mold 3 is divided into a standard arc mold 51, an end arc mold 52 and a non-standard arc mold 53;

[0038] There are several groups of standard arc molds 51, and any two standard arc molds 51 have the same specifications and the ends of adjacent standard arc molds 51 are sealed and fitted;

[0039] One end of the end arc mold 52 is fitted with the end of the standard arc mold 51, and the side plate of the other end of the end arc mold 52 is sealed and fitted with the end of the column 9;

[0040] The length of the non-standard arc mold 53 is indefinite, and it is installed in the gap reserved between the two standard arc molds 51 , and the two ends of the non-standard arc mold 53 are sealed and fitted with the corresponding ends of the standard arc mold 51 .

[0041] like Figure 1 As shown: Generally speaking, the arc mold 3 here is divided into three types according to the needs. One is the standard arc mold 51, and its specifications are equal. The more standard arc molds 51 there are, the lower the production cost. Here, during construction, it may be considered to lay out the construction from both sides to the middle. Since most of the cases in the middle will reserve space where the standard arc mold 51 cannot be placed, the space only needs to be equipped with a non-standard arc mold 53. Correspondingly, since the two ends need to fit with the column, the end of the end arc mold 52 close to the column needs to extend toward the column 9 and seal with the end of the column 9 (generally the upper surface of the column).

[0042] like Figure 7 As shown: In the utility model, each component in the arc-shaped mold is accurately drawn using CAD drawing software, and then with the help of CAD software, the material cutting is accurate and intuitive, which is convenient for standardized construction and fast in construction speed. Thus, the problem of inaccurate positioning of the arc beam is successfully solved. CAD layout is centrally managed, material cutting is unified, material waste is reduced, and cost is saved.

[0043] The material of the arc mold 3 is a 5 cm steel plate. In order to prevent the arc beam side mold from expanding during the concrete pouring process, the material of the arc mold 3 is a 5 cm steel plate. The strength is effectively improved and the expected effect is achieved.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
