[0031] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-11 As shown, a slab-frame separable formwork for concrete construction includes a support frame 1. The support frame 1 is a grid structure, which is composed of horizontal ribs 101 and vertical ribs 102 arranged in a crisscross pattern. The front and rear sides of the support frame 1 are a support side 103 and a positioning side 104, respectively. At least one of the horizontal ribs 101 has a plurality of insertion holes 1012 arranged at intervals along the transverse direction. A support plate 2 is detachably installed on the support side 103 of the support frame 1. The support plate 2 has through holes 201 that correspond one-to-one with the positions of the insertion holes 1012. The horizontal ribs 101 with insertion holes 1012 arranged at intervals along the transverse direction are reinforcing parts 1011, and the reinforcing parts 1011 are located on the support side 103. The end face has a groove 1014, and the insertion holes 1012 are all connected to the groove 1014. The end of the insertion hole 1012 near the support side 103 has a countersunk groove 1013, and the diameter of the countersunk groove 1013 is larger than the diameter of the insertion hole 1012. It also includes: a reinforcing plate 3, which is inserted into the groove 1014 and located between the reinforcing part 1011 and the support plate 2. The reinforcing plate 3 has a number of connecting pipes 301, and the positions of the connecting pipes 301 and the insertion holes 1012 correspond one-to-one. The connecting pipes 301 have connecting holes 302 that communicate with the insertion holes 1012. The connecting holes 302 penetrate the reinforcing plate 3, and the connecting pipes 301 are inserted into the countersunk grooves 1013.

[0034] In use, the recess 1014 is formed on the reinforcing part 1011 to facilitate insertion of the reinforcing plate 3, which does not protrude from the support side 103 of the support, and the support plate 2 can be attached to the support side 103 on one side and in contact with the concrete on the other side. The support plate 2 is detachably connected to the support frame 1 by screws or other connectors, which is a prior art and will not be described herein. The detachable support plate 2 and support frame 1 are used, but the support plate 2 can be replaced individually when damaged. The reinforcing plate 3 can be made of steel plate, stainless steel plate, etc. The support frame 1 is generally made of plastic or other materials. The steel plate can strengthen the structural strength of the support plate 2, making it more stable during pouring and increasing the service life.

[0035] The connecting pipe 301 on the reinforcing plate 3 is inserted into the counterbore groove 1013, and the reinforcing plate 3 and the support frame 1 are connected more stably by plug-in connection, which can effectively strengthen the structural strength of the support frame 1. When two forms are vertically combined and connected by a corner connector, the screw passes through the corner connector, the through hole 201 of the support plate 2, the connecting hole 302 of the reinforcing plate 3, and the plug-in hole 1012 of the support frame 1 in turn, and is fixed by a nut or other locking member. When the screw is positioned, the end of the plug-in hole 1012 is the connecting pipe 301, which provides support force for the screw as a support point, reducing the extrusion damage of the screw to the end of the plug-in hole 1012 and improving the service life.

[0036] Before pouring the concrete, the installation side is supported and positioned by a support, and connected side by side by a connector. The plugging of the excess hole structure (connecting hole 302, plug-in hole 1012, through hole 201) when using a hole template is a prior art and will not be described herein.

[0037] Further, the diameter of the connecting hole 302 is not less than the diameter of the plug-in hole 1012. The diameter of the connecting hole 302 is less than the diameter of the through hole 201.

[0038] In use, in the axial direction, the diameters of the plug-in hole 1012, the connecting hole 302, and the through hole 201 increase in turn, and when the screw passes through them in turn, it mainly contacts the connecting pipe 301, which plays a major supporting role. When the diameters of the plug-in hole 1012 and the connecting hole 302 are equal, the plug-in hole 1012 and the connecting hole 302 limit the screw in the radial direction at the same time, but the connecting rod at the end is still the main support point.

[0039] Further, the connecting pipe 301 is stamped from the reinforcing plate 3.

[0040] In use, the connecting pipe 301 can be fixed on the reinforcing plate 3 in the form of bonding or welding, and can also be formed in the structure of the connecting pipe 301 by one-piece stamping. By using a punch, the connecting pipe 301 structure protruding from the reinforcing plate 3 can be vertically punched at the corresponding position of the reinforcing plate 3 under the action of the mold, and the end of the connecting pipe 301 is punched through to form the connecting hole 302. One-piece stamping is faster and more convenient, accurate in position, and convenient for batch production.

[0041] Further, the end face of one of the horizontal ribs 101 or one of the vertical ribs 102 located at the support side 103 has a first pressing groove 1031, the first pressing groove 1031 has a gap between the end face of the positioning side 104, the end face of the positioning side 104 has a second pressing groove 1041, the first pressing groove 1031 and the second pressing groove 1041 are staggered in the vertical direction, and the first pressing groove 1031 and the second pressing groove 1041 are communicated in the vertical direction, for forming a holding part 105 at the positioning side 104, the holding part 105 is located beside the second pressing groove 1041 in the vertical direction.

[0042] When using the formwork, although large machinery can be used for transportation in the existing construction environment, in actual operation, the formwork sometimes still needs to be manually transported, such as on-site assembly, especially short-distance transportation upstairs and downstairs, manual transportation is better for operation, and the existing formwork is mostly of a plate-frame separation type, the support frame 1 is a grid structure with horizontal and vertical ribs 101 and 102 arranged in a crisscross manner. When manually transporting a large formwork, it is more laborious to rely on both hands to lift the formwork, and generally a shoulder-carrying force is used for transportation. The longer side of the formwork is placed vertically for easy movement at the corner, the formwork is located on one side of the body and leans against the shoulder position, the body is slightly inclined, one hand drags one of the horizontal ribs 101 on the lower side or lower part of the formwork, and the other hand holds one of the horizontal ribs 101 or vertical ribs 102 of the grid structure to stabilize the formwork. When holding the horizontal rib 101, it is more laborious to pinch the horizontal rib 101, which can easily cause finger numbness and formwork damage over a long period of time. In the present application, the holding part 105 is provided, which can be conveniently held by a worker with one hand, which is more labor-saving and stable. The vertical direction is the direction in which the vertical rib 102 is arranged, and a plurality of vertical ribs 102 are arranged in an array in the horizontal direction, and a plurality of horizontal ribs 101 are arranged in an array in the vertical direction.

[0043] The holding part 105 is integrally formed with the support frame 1, meets the production process of demolding in the up-down direction, and does not need to be separately processed. The first pressing groove 1031 is opened on the support side 103, the second pressing groove 1041 is opened on the positioning side 104, the first pressing groove 1031 and the second pressing groove 1041 are communicated at the middle position of the horizontal rib 101, then the fingers can pass through the space communicated by the two, and hold the holding part 105. The arrangement of the holding part 105 saves the physical strength of workers, avoids that the fingertips excessively consume physical strength to cause the formwork to be unstable, can reduce the situation that the formwork is not supported and falls, is beneficial to protecting the formwork, and improves the service life.

[0044] Similarly, the holding part 105 can be arranged on the plurality of horizontal ribs 101 and / or vertical ribs 102.

[0045] Further, the side, away from the second pressing groove 1041, of the holding part 105 is provided with the transversely arranged reinforcing edge 1051.

[0046] In use, the reinforcing edge 1051 is convex to one side of the holding part 105, and the strength of the holding part 105 can be improved. The reinforcing edge 1051 can be integrally formed with the holding part 105, and the reinforcing edge 1051 is located at the side, away from the second pressing groove 1041, of the holding part 105, and the reinforcing edge 1051 can be formed in the up-down demolding process.

[0047] It can be understood that the utility model is described through some embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model.
