Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anti-floating tool for inner membrane of a concrete inclined surface. Background Art

[0002] The inner membrane is an extruded board, which is placed and installed in the formwork during concrete pouring to form a cavity after pouring. When pouring concrete on an anisotropic slope, after the outer wooden formwork is erected and the inner membrane is installed, the concrete is poured. Due to the height difference of the slope, during the concrete pouring process, the pressure at the lower end of the slope will be greater than the pressure at the upper end. At the same time, since the concrete itself has a certain buoyancy, the inner membrane will float up during concrete pouring, resulting in position displacement. This will cause the position of the cavity to change after the concrete is poured and formed, thereby affecting the overall stability of the building. Therefore, we designed an anti-floating tooling.

[0003] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-8 The utility model provides a technical solution: a concrete inclined surface inner membrane anti-floating tool, comprising two wooden molds 1 and an inner membrane body 2 arranged between the two wooden molds 1, used to form a cavity after concrete pouring and solidification, the inner membrane body 2 is an extruded board, and also includes:

[0037] A plurality of pressing plates 3 are rotatably arranged on the wooden mold 1 via a rotating shaft 4, and the shape of the pressing plates 3 is adaptively arranged according to the upper surface of the casting trough formed by forming the wooden mold 1;

[0038] The pressing assembly 5 is arranged on the pressing plate 3 and is used to press and fix the pressing plate 3 on the upper surface of the poured concrete when pouring concrete;

[0039] Among them, Figure 1 , 2 The figure in the figure is a schematic diagram when there are 3 groups of extruded plates, but the actual number is not 3. This figure is used as a simplified diagram to facilitate understanding of the connection principle at the pressing plate;

[0040] The reinforcement assembly 6 is arranged on the pressing plate 3 and is used to reinforce the inner membrane body 2 when pouring concrete.

[0041] The rotating shaft 4 for rotating the pressing plate 3 is located at the lower side end of the pressing plate 3, so that when the pressing plate 3 is installed on the wooden form 1, the pressing plate 3 will be in a vertical state under gravity, and then the concrete will be poured, and the concrete in the casting groove formed by the wooden form 1 will rise, and the pressing plate 3 will also rotate accordingly until the upper end surface of the wooden form 1 is covered, thereby realizing the cover of the upper surface of the casting groove. Since the upper surface of the wooden form 1 is inclined upward, during actual casting, segmented casting is performed according to the number of pressing plates 3. The pressing assembly 5 includes:

[0042] The limiting plate 51 is fixedly arranged on the wooden formwork 1 and is used to limit the rotation angle of the pressing plate 3, so that the pressing plate 3 of this section can be kept flush with the wooden formwork 1 of this section after limiting. In this way, under the action of the concrete itself, that is, the wooden pressing plate 3 has a certain buoyancy thereon, and the inclined shape of the wooden formwork 1, due to the inconsistent pressure from top to bottom, the pressure on the lower end of the pressing plate 3 will be greater than the pressure on the upper end. In this way, after the concrete is poured, the pressing plate 3 will be fixed with the action of the limiting plate 51, that is, after the concrete is poured, the pressing plate 3 will be at the limiting angle of the limiting plate 51;

[0043] The laminating plate 52 is fixedly arranged at the lower surface end of the pressing plate 3 located at the upper end of two adjacent pressing plates 3, and the other adjacent pressing plate 3 is provided with a laminating groove 53 for laminating. The laminating plate 52 and the laminating groove 53 can make the two adjacent pressing plates 3 fit tightly during pressing to prevent concrete from leaking therefrom. Since the upper surface of the wooden formwork 1 is arranged obliquely, due to the height difference, concrete is easily leaked from the connection between the two pressing plates 3 below, so as to solve this problem and make the connection more tightly;

[0044] The two scraping parts 54 are arranged at adjacent positions of the two pressing plates 3 and are used to scrape away concrete residues adhered to the upper end of the bonding plate 52 and the surface of the bonding groove 53 during the rotation and covering process of the pressing plates 3 .

[0045] The scraping unit 54 includes:

[0046] Two shovel plates 541 are slidably disposed at the upper ends of the laminating plates 52 and the upper ends of the laminating grooves 53 of the two pressing plates 3, respectively;

[0047] The power unit 542 is disposed between the shovel plate 541 and the wooden mold 1, and is used to drive the shovel plate 541 to perform a telescopic sliding when the pressing plate 3 rotates to the angle of the limiting plate 51.

[0048] Wherein, the power unit 542 includes:

[0049] Two guide plates 5421 are arranged on both sides of the wooden mold 1, and the guide plates 5421 are provided with folding slide grooves 5422;

[0050] The connecting plate 5423 is fixed to the shovel plate 541 at one end, and the other end passes through the pressing plate 3 to the upper end of the pressing plate 3 and is provided with a guide roller 5424. Both ends of the guide roller 5424 are slidably arranged in the folding slide groove 5422 of the guide plate 5421. The pressing plate 3 is provided with a sliding groove 5425 for the sliding of the connecting plate 5423.

[0051] When pouring concrete, when the pressing plate 3 is driven to rotate, the guide roller 5424 will slide in the folding groove 5422, thereby driving the shovel plate 541 to slide through the connecting plate 5423, realizing a telescopic sliding, thereby cleaning the concrete stuck to the position when pouring concrete, so that the two adjacent pressing plates 3 can fit more closely.

[0052] In addition, the two sides of the wooden mold 1 are provided with rotating half grooves 5426 for mounting the rotating shaft 4, and the two ends of the rotating shaft 4 are provided with fixing mechanisms for limiting the upper and lower positions of the rotating shaft 4 at the wooden mold 1;

[0053] Wherein, the fixing mechanism comprises:

[0054] The fixed block 5427 is slidably arranged on the wooden mold 1, and a circular groove for limiting the other side of the rotating shaft 4 is arranged on the fixed block 5427, and a limiting sliding groove for the sliding of the fixed block 5427 is arranged on the wooden mold 1;

[0055] A fixing spring 5428 is disposed in the limiting slide groove and is used to increase the pressing force of the fixing block 5427;

[0056] The fixed block 5427 can be pulled toward both sides of the limiting slide groove, and then the rotating shaft 4 of the pressing plate 3 is placed on the rotating half groove 5426, and then the fixed block 5427 is released. The fixed block 5427 will move under the action of the fixing spring 5428, thereby limiting the upper half of the rotating shaft 4, thereby achieving fixation. After the concrete is fixed, the fixed block 5427 is removed and the pressing plate 3 can be removed.

[0057] Finally, the reinforcement assembly 6 comprises: an elastic telescopic rod 61, one end of which is fixed to the inner arm side of the pressing plate 3, and the other end of which is fixed with a reinforcement plate 62 for abutting against the extruded plate 7;

[0058] When the pressing plate 3 rotates to the angle of the limiting plate 51, the elastic telescopic rod 61 contracts to the minimum length and squeezes the extruded plate 7 at the same time, thereby preventing the buoyancy of the concrete after pouring from causing the extruded plate 7 to float up, thereby affecting the deformation of the thin-walled cavity after molding.
