Description

Technical Field

[0001] This utility model relates to the technical field of casting templates, and in particular to a prefabricated casting template for buildings. Background Technology

[0002] Currently, during the construction process, concrete is poured onto the erected steel cage. At this time, a pouring formwork is needed to surround the surface of the steel cage before the concrete can be poured.

[0003] When pouring concrete for a cylindrical support pier, it is necessary to use two or more molds to enclose the pouring area and fix multiple pouring templates. Common fixing methods include:

[0004] 1. Bolted type: There are mounting holes between two adjacent casting templates, and the two casting templates are fixed together by bolts. However, connecting multiple casting templates requires a large number of bolts, which requires special personnel to transport and install them, which is time-consuming and labor-intensive.

[0005] 2. Clamp type: The casting formwork has slots and blocks, both arranged in a T-shape to ensure stability between adjacent casting slabs. Multiple casting slabs are fixed together by clamps. However, connecting adjacent casting slabs requires raising one slab higher than the other, which is cumbersome. Therefore, it is necessary to invent a prefabricated casting formwork to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated casting template for buildings to solve the technical problem of time-consuming and labor-intensive connection and installation between two adjacent casting slabs in the above-mentioned background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated casting template for buildings, comprising an arc-shaped plate, wherein multiple arc-shaped plates are combined to form a circular casting template;

[0008] The two ends of the arc-shaped plate have a first end groove and a second end groove respectively. The first end groove and the second end groove between two adjacent arc-shaped plates cooperate to form a receiving cavity. The inside of the receiving cavity has a positioning unit so that the two adjacent arc-shaped plates can be connected.

[0009] The positioning unit includes an arc plate and a cylinder. The arc plate has an arc groove corresponding to the cylinder. Both ends of the arc plate have mounting plates. A transmission rod is fixedly connected to the mounting plate. A clamping block is connected to the end of the transmission rod facing the cylinder. The two transmission rods move relative to each other to press the arc plate, so that the two clamping blocks contact the cylinder, thereby realizing the assembly between two adjacent arc plates.

[0010] Optionally, the transmission rod extends through the second end groove to the outer side of the arc-shaped plate. A driving unit is provided between the two transmission rods. The driving unit includes two threaded sleeves and two screws. The two threaded sleeves are rotatably connected to each other. The two screws are threadedly connected to the two threaded sleeves. A hinge sleeve is hinged to the end of the screw away from the threaded sleeve. The hinge sleeve is fixed to the transmission rod.

[0011] Optionally, the threaded sleeve has a hexagonal retaining sleeve.

[0012] Optionally, the arc plate is a plate with a deformation effect.

[0013] Optionally, a first positioning groove is provided on the second end groove, and the transmission rod is located in the first positioning groove, the width of the first positioning groove being equal to the diameter of the transmission rod.

[0014] Optionally, the upper end of the arc-shaped plate is provided with a second positioning groove, and the lower end of the arc-shaped plate is provided with a positioning plate, which is used in conjunction with the second positioning groove.

[0015] Optionally, the arc plate has multiple portions and is arranged at equal intervals along the length of the arc plate.

[0016] Optionally, the arc plate is mounted on the second end groove via a first fixing plate, and the cylinder is mounted on the second end groove via a second fixing plate.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] In this invention, the relative movement between two transmission rods causes the arc plate to be compressed at both ends and move closer to the cylinder, thereby making the clamping block contact the cylinder and completing the connection and fixation between two adjacent arc plates. This replaces the method of connecting two cast plates by snapping or bolting. The installation between the two arc plates can be completed simply by assembling and rotating the threaded sleeve between the two cast plates. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figures 1-6 The diagram illustrates a prefabricated casting formwork for construction, comprising multiple arc-shaped plates 100, which are combined to form a circular casting formwork. Each arc-shaped plate 100 has a first end groove 110 and a second end groove 120 at its two ends. The first end groove 110 is located on the outer side of the arc-shaped plate 100, and the second end groove 120 is located on the inner side. The first end groove 110 and the second end groove 120 between two adjacent arc-shaped plates 100 cooperate to form a receiving cavity 200. The receiving cavity 200 has positioning units inside to connect adjacent arc-shaped plates 100.

[0033] The positioning unit includes an arc plate 400 and a cylinder 300. The arc plate 400 has an arc-shaped groove corresponding to the cylinder 300. Specifically, there are multiple arc plates 400 arranged at equal intervals along the length of the arc plate 100. This reduces material usage while increasing the connection points between the arc plate 400 and the cylinder 300. The cylinder 300 is positioned along the length of the arc plate 100. The arc plate 400 is mounted on the second end groove 120 via a first fixing plate, and the cylinder 300 is mounted on the second end groove 120 via a second fixing plate. Both ends of the arc plate 400 have mounting plates 410. Specifically, the arc plate 400 is a deformable plate to prevent it from being rigid and thus preventing both ends from contacting the cylinder 300. A transmission rod 500 is fixedly connected to the mounting plate 410. A clamping block 520 is connected to one end of the transmission rod 500 facing the cylinder 300. The two transmission rods 500 move relative to each other to press the arc plate 400, so that the two clamping blocks 520 come into contact with the cylinder 300, thereby realizing the assembly between two adjacent arc plates 100.

[0034] Specifically, by moving relative to each other between the two transmission rods 500, the two ends of the arc plate 400 are compressed and move closer to the cylinder 300, thereby making the clamping block 520 contact the cylinder 300, thus completing the connection and fixation between the two adjacent arc plates 100. This replaces the method of connecting the two cast plates by snapping or bolting. The installation between the two arc plates 100 can be completed simply by assembling and rotating the threaded sleeve 610 between the two cast plates.

[0035] The transmission rod 500 extends through the second end slot 120 to the outer side of the arc-shaped plate 100. A drive unit is provided between the two transmission rods 500. The drive unit includes two threaded sleeves 610 and two screws 620. Specifically, the threaded sleeves 610 have anti-slip threads, which can be manually tightened first and then tightened with tools when the diameter of the arc-shaped plate 100 is large. There is a gap between the threaded sleeves 610 and the arc-shaped plate 100 to prevent the threaded sleeves 610 from having no room to move when the transmission rods 500 move. The two threaded sleeves 610 are rotatably connected. Specifically, one threaded sleeve 610 has a protrusion and the other threaded sleeve 610 has a groove. The protrusion is inserted into the groove, and a bearing is installed between the protrusion and the groove. The two screws 620 are threaded into the two threaded sleeves 610 respectively. The end of the screw 620 away from the threaded sleeve 610 is hinged to a hinge sleeve 510, which is fixed to the transmission rod 500. The threaded sleeve 610 has a hexagonal retaining sleeve 630 to facilitate the turning of the threaded sleeve 610 with a tool. In another embodiment, the outer side of the threaded sleeve 610 is hexagonal.

[0036] Specifically, by manually rotating the two threaded sleeves 610 in opposite directions using tools, the two screws 620 are extended or retracted. On the one hand, the two screws 620 drive the two transmission rods 500 to move in opposite directions, causing the screws 620 to extend and thus fix the arc plate 400 and the cylinder 300. On the other hand, the two screws 620 drive the two transmission rods 500 to move towards each other, causing the screws 620 to retract and thus release the fixation between the arc plate 400 and the cylinder 300.

[0037] A first positioning groove 121 is provided on the second end groove 120. The transmission rod 500 is located in the first positioning groove 121. The width of the first positioning groove 121 is equal to the diameter of the transmission rod 500. The first positioning groove 121 can limit the position of the transmission rod 500, so that the transmission rod 500 slides according to the preset position and plays a guiding role for the transmission rod 500.

[0038] The upper end of the arc-shaped plate 100 is provided with a second positioning groove 130, and the lower end of the arc-shaped plate 100 is provided with a positioning plate 140. The positioning plate 140 and the second positioning groove 130 are used together to enable the upper and lower adjacent casting templates to be better connected together, ensuring the stability of the connection between the upper and lower adjacent casting templates and avoiding gaps caused by pressure between the upper and lower adjacent casting templates.

[0039] The working method of this utility model:

[0040] After the first end groove 110 and the second end groove 120 on two adjacent arc plates 400 correspond to each other, the arc plate 400 corresponds to the cylinder 300. At this time, the mounting plates 410 at both ends of the arc plate 400 are parallel.

[0041] At the same time, the two threaded sleeves 610 rotate in opposite directions. The two threaded sleeves 610 cause the two screws 620 to move relative to each other, which in turn causes the adjacent ends of the two transmission rods 500 to move relative to each other, thereby causing the two transmission rods 500 to drive the mounting plate 410 on the arc plate 400 to move closer to the cylinder 300.

[0042] When the clamping block 520 contacts the cylinder 300, the arc plate 400 and the clamping block 520 fix the cylinder 300, thereby realizing the connection between two adjacent arc plates 400, thus solving the problem of inconvenience in connecting two adjacent casting templates by snap-fit ​​method.

[0043] When disassembling between the two arc-shaped plates 100, simply twist the two threaded sleeves 610 to separate the arc plate 400 from the cylinder 300.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
