Description

Technical Field

[0001] This utility model relates to the technical field of building insulation structures, specifically a limiter for pouring sandwich-insulated concrete. Background Technology

[0002] With the continuous development of modernization, adding insulation boards to the exterior walls of buildings is very important. In summer, insulation boards can insulate against the outside temperature, keeping the interior temperature constant. In winter, they also insulate against the cold outside air, maintaining a constant interior temperature. Adding insulation boards to the exterior of buildings can improve the comfort of living, reduce energy waste, and make the environment more low-carbon and environmentally friendly.

[0003] The cast-in-place concrete sandwich insulation system uses connectors to fix the insulation board and wire mesh to the reinforced steel structure, and inner and outer formwork is fixedly installed on both sides of the structure. Then, the insulation board, wire mesh and other structures are fixed by pouring concrete. However, during the concrete pouring process, the inner and outer formwork are used to limit the concrete, but the tops of the inner and outer formwork often become too far apart due to the surface tension of the liquid concrete or vibration, resulting in unevenness after the concrete is formed. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a limiter for pouring sandwich insulated concrete, so as to solve the problem that the gap between the top of the inner and outer formwork is easily increased during the pouring of concrete in the current cast-in-place sandwich insulation system.

[0005] The technical solution adopted by this utility model is a limiter for pouring sandwich insulated concrete, including a support plate. First limit plates are respectively provided at both ends of the support plate. The first limit plates abut against the outer side of the inner template and the outer template, respectively. A handle is provided on the top surface of the support plate. Two second limit plates for being embedded in the outer side of the insulation board are also provided between the two first limit plates.

[0006] The above structure has the following beneficial effects:

[0007] 1. Two first limiting plates are installed on the outside of the inner and outer templates respectively to limit the dimensions of the ends of the inner and outer templates, preventing the relative position of the inner and outer templates from changing during concrete pouring, thereby ensuring the quality of concrete forming.

[0008] 2. The second limiting plate can be embedded in both sides of the insulation board, which can ensure that the relative position between the insulation layer and the inner and outer formwork remains unchanged during concrete pouring. This can prevent damage to the insulation board and improve the stability of the insulation effect of the entire sandwich insulation structure.

[0009] Preferably, the first limiting plate and the support plate are slidably connected, and a first locking mechanism is provided between the first limiting plate and the support plate.

[0010] The first limiting plate is slidably connected to the support plate, allowing the position of the first limiting plate to be adjusted. This makes it suitable for concrete pouring of different thicknesses and allows for adjustment of the distance between the first and second limiting plates on both sides as needed. It also facilitates the installation of the limiter. The limiter can be installed at the ends of the inner and outer templates first, and then the position of the first limiting plate can be adjusted to clamp the inner and outer templates before being fixed by the first locking mechanism.

[0011] Preferably, the first locking mechanism includes a locking bolt fixedly connected to the first limiting plate, a first sliding groove for the locking bolt to slide on the support plate, and a locking nut for locking the first limiting plate and the support plate is also connected to the locking bolt.

[0012] The locking bolt can move within the first groove, which facilitates the adjustment of the relative position between the first limiting plate and the support plate. On the other hand, the first groove limits the position of the first limiting plate, preventing it from separating from the support plate. Tightening the locking nut fixes the relative position between the first limiting plate and the support plate, making it simple and quick.

[0013] Preferably, the bottom surface of the support plate is provided with a plurality of first teeth, and a check plate is also connected to the first limiting plate. The check plate is made of elastic material, the lower end of the check plate is fixedly connected to the first limiting plate, the upper end of the check plate is a bent section, and the end of the bent section abuts against the first teeth.

[0014] By abutting the end of the bent section of the check plate against the first tooth, the first limiting plate is limited, preventing the first limiting plate from moving away from the other first limiting plate, thereby ensuring that the relative distance between the two first limiting plates does not change during the pouring process.

[0015] Preferably, the first tooth has a triangular cross-section, and the side of the first tooth facing the middle of the support plate is a vertical surface.

[0016] The cross-section of the first tooth is set as a triangle, so that the end of the bent section of the check plate can move along the inclined surface of the first tooth. Under the elastic action of the check plate, when the end of the bent section passes through the first tooth, it will be stuck in the vertical surface of the first tooth. With this setting, the first limiting plate can only move in the direction of decreasing spacing and cannot move in the opposite direction. This facilitates the installation of the limiter and realizes the function of automatic limiting, thus improving installation efficiency.

[0017] Preferably, the bottom surface of the support plate is also provided with a groove, and the first tooth is located inside the groove.

[0018] The groove design ensures that the first support plate will not be interfered with by the first tooth during movement, thus ensuring smooth movement of the first support plate.

[0019] Preferably, a scale is provided on the top surface of the support plate.

[0020] The scale makes it easy to confirm the position of the first limiting plate, so as to adjust the fixed position of the first limiting plates on both sides.

[0021] Preferably, an adjustment mechanism is provided between the first limiting plate and the support plate. The adjustment mechanism includes a plurality of second teeth provided on the top surface of the support plate. An adjustment shaft is rotatably connected to the first limiting plate. An adjustment gear that meshes with the second teeth is connected to the adjustment shaft. An adjustment knob is also fixedly connected to the end of the adjustment shaft.

[0022] The adjustment mechanism drives the adjustment gear to move along the second tooth by rotating the adjustment knob, which enables more precise position adjustment of the first limit plate and ensures that the position of the first limit plate meets the construction requirements.

[0023] Preferably, the side of the first limiting plate is provided with a second sliding groove, the support plate is slidably connected in the second sliding groove, and a bearing seat for connecting the adjusting shaft is installed on the top surface of the second sliding groove.

[0024] The second slide groove can further guide and limit the movement of the support plate and the first limiting plate. At the same time, the setting of the bearing seat ensures that the adjusting gear is stably engaged with the second tooth, so that it can stably adjust the position.

[0025] Preferably, the support plate is also connected to several third limiting plates.

[0026] The third limiting plate is used to limit the steel wire mesh in the sandwich insulation system, ensuring that the relative positions of the steel wire mesh and the insulation layer, as well as the inner and outer templates, do not easily change. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] According to the instruction manual Figure 1-2As shown, this utility model provides a limiter for pouring sandwich insulated concrete 81, including a support plate 10 and first limiting plates 20 installed at both ends of the support plate 10. Two second limiting plates 30 are also installed between the two first limiting plates 20. The first limiting plates 20 and the second limiting plates 30 are all installed on one side of the support plate 10, and a handle 11 is installed on the other side of the support plate 10. In this embodiment, a third limiting plate 71 is also installed on the support plate 10, and the third limiting plate 71 is on the same side as the first limiting plates 20 and the second limiting plates 30.

[0039] Its working principle is as follows: when the sandwich insulated concrete 81 needs to be poured, the first limiting plates 20 at both ends of the support plate 10 are respectively embedded in the outer side of the inner template 83 and the outer template 84, while the two second limiting plates 30 are respectively embedded in the two sides of the insulation board 82, and the third limiting plate 71 is embedded in one side of the wire mesh 86. During the pouring of the concrete 81, the inner template 83, the outer template 84, the insulation board 82 and the wire mesh 86 are limited to ensure that they will not move during the pouring process. After the concrete 81 is poured, the limiting device can be taken out by pulling the handle 11 for subsequent reuse.

[0040] Example 2

[0041] According to the instruction manual Figure 3-7 As shown, the difference between this embodiment and embodiment 1 is that the first limiting plate 20 is "L" shaped, the first limiting plate 20 is slidably connected to the support plate 10, and a first locking mechanism 40 is provided between the first limiting plate 20 and the support plate 10. The first locking mechanism 40 includes a locking bolt 41 fixedly installed on the first limiting plate 20, a first sliding groove 43 is provided on the support plate 10, the locking bolt 41 slides in the first sliding groove 43, and a locking nut 42 for fixing the first limiting plate 20 to the support plate 10 is also installed on the locking bolt 41.

[0042] In this example, a groove 13 is provided on the bottom surface of the support plate 10, and a plurality of first teeth 12 are provided in the groove 13. The cross-section of the first teeth 12 is a right triangle, and the side of the first teeth 12 facing the middle of the support plate 10 is a vertical surface. At the same time, a check plate 51 is also installed on the first limiting plate 20. The check plate 51 is an elastic plate. The lower end of the check plate 51 is fastened or welded to the first limiting plate 20. The upper end of the check plate 51 is a bent section 52, and the end of the bent section 52 abuts against the first teeth 12 under its elastic action.

[0043] A scale 14 is also installed on the top surface of the support plate 10, wherein the scale 14 is located on one side of the first slide groove 43.

[0044] The working principle of this embodiment is as follows: When installing the limiter, the support plate 10 is first placed on the inner template 83 and the outer template 84, and the two second limit plates 30 are embedded in the insulation board 82. Then, the first limit plates 20 on both sides are pushed to move towards the center. During the movement of the first limit plates 20, the check plate 51 moves along the inclined surface of the first tooth 12. When the end of the check plate 51 passes each first tooth 12, it is embedded in the vertical surface of the first tooth 12 to prevent the first limit plate 20 from moving in the opposite direction. When the first limit plates 20 on both sides abut against the inner template 83 and the outer template 84 respectively, the locking nut 42 is tightened to fix the first limit plate 20 on the support plate 10, and the concrete 81 pouring work can begin. After the pouring work is completed, the limiter is removed and the locking knob is loosened, so that the check plate 51 can be separated from the first tooth 12, so that the first limit plate 20 can be pulled open for reuse.

[0045] Example 3

[0046] According to the instruction manual Figure 8 As shown, the difference between this embodiment and embodiment 2 is that an adjustment mechanism 60 is also provided between the first limiting plate 20 and the support plate 10. The adjustment mechanism 60 includes a plurality of second teeth 61 provided on the top surface of the support plate 10. Second sliding grooves 21 are also provided on both sides of the first limiting plate 20, and the support plate 10 slides in the second sliding grooves 21. The movement of the support plate 10 and the first limiting plate 20 can be further guided and limited by the second sliding grooves 21. A bearing seat 65 is also installed on the first limiting plate 20. An adjustment shaft 62 is rotatably connected to the bearing seat 65. An adjustment gear 64 that meshes with the second teeth 61 is connected to the adjustment shaft 62, and an adjustment knob 63 is fixedly connected to the end of the adjustment shaft 62.

[0047] The working principle of this embodiment is that when adjusting the position of the first limiting plate 20, the first support plate 10 can be moved by rotating the adjustment knob 63 through the meshing of the adjustment gear 64 and the second tooth 61. This adjustment method is more precise and improves the casting quality.
