Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of assembled precast components, and particularly relates to an assembled composite floor slab mold. Background Technique
[0002] An assembled concrete composite floor slab (hereinafter referred to as a composite slab) is a new type of assembled building material with high strength, strong plasticity and simple construction. During the construction process, the composite slab can not only effectively shorten the construction period, but also effectively reduce the construction cost, so as to achieve true demolition-free.
[0003] The composite slab is composed of a lower layer steel mesh, a steel truss and concrete. During the production and manufacturing process, it is necessary to customize the corresponding mold models according to the given component shape nodes. The commonly used mold profiles include angle iron materials and aluminum profiles, as well as the latest magnet stainless steel integrated mold. Among them, the magnet stainless steel integrated mold is mostly used in projects with a single floor slab size specification.
[0004] At present, most of the industry still uses angle iron and aluminum profile molds to manufacture composite slabs. Among them, angle iron is used for the mold in the direction of the floor slab extending reinforcement, and aluminum profile mold is used in the non-extending reinforcement direction.
[0005] The technical defect of the aluminum profile mold in the non-reinforcement direction is as follows:
[0006] There are two styles of bevel edges and straight edges on the non-reinforcement side. On the one hand, the traditional aluminum profile mold uses two customized profiles to make the two styles, and it is necessary to constantly change the mold according to the production of different models of floor slabs, consuming a lot of manpower and material resources; on the other hand, both the straight edge and the bevel edge are the new and old concrete joint surfaces from the concrete requirements, and it is necessary to set a rough surface, especially the inclined surface. The side joint nodes of the two composite slabs present an inverted "V" notch, and the later joint filling is not firm, easy to crack, and even fall off. Content of the Utility Model
[0007] The main purpose of the utility model is to provide an assembled composite floor slab mold that does not need to replace the mold when producing different models of components.
[0008] The assembled composite floor slab mold provided by the utility model includes a bevel edge mold and a straight edge mold; two bevel edge molds and two straight edge molds are respectively crossed and connected end to end to form a rectangular frame, and the bevel edge mold is a ribbed structure.
[0009] In an implementation manner of the above mold, the bevel edge mold is made of aluminum profile, and its cross-section is approximately in the shape of a Japanese character.
[0010] In an implementation manner of the above mold, both sides of the cross-section of the bevel edge mold are multi-layer concave corrugated rib plates.
[0011] In one embodiment of the above mold, the bottom end of the bevel mold has two legs extending in length.
[0012] In one embodiment of the above-mentioned mold, the straight-edge mold is an angle iron profile with an L-shaped cross-section, and deep U-shaped holes are opened on its vertical edges at fixed intervals.
[0013] In one embodiment of the above-mentioned mold, the beveled edge mold and the straight edge mold are fixed by welding.
[0014] In one embodiment of the above mold, the vertical edges of the two straight-edge molds are both facing inwards.
[0015] The beneficial effects of the utility model are:
[0016] 1. Integrate the straight-edge mold and the beveled-edge mold into one to increase the applicability of the mold. During the manufacturing process, when the previous beveled-edge laminated plate needs to be re-molded into a straight-edge side laminated plate, the mold change can be completed by simply swapping the side of the mold. There is no need to replace the mold during production, which reduces the material loss and labor hours caused by frequent mold changes in the production of different types of components.
[0017] 2. The beveled edge mold adopts a ribbed design to increase the contact area between the new and old concrete, forming a multi-layer concave structure to facilitate the stable combination of the later filling materials and the composite board; solving the problems of looseness, easy cracking, and even falling caused by the later filling of the project.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the relevant technical solutions. Obviously, the described embodiments are only part of the embodiments, 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.
[0023] like Figure 1As shown, the prefabricated composite floor slab mold disclosed in this embodiment includes a bevel mold 1 and a straight-edge mold 2.
[0024] Two bevel molds 1 and two straight-edge molds 2 are respectively cross-connected head to tail to form a rectangular frame.
[0025] Combined Figure 2 and Figure 3 It can be seen that the bevel mold 1 is made of aluminum profile, and its cross-section is approximately in the shape of a Chinese character 'Ri'. The two sides of the cross-section of the bevel mold are multi-layer concave corrugated rib plates. By setting the rib plates with this structure, the contact area between the new and old concretes is increased, promoting the stable combination of the later-stage caulking material and the composite slab. There are two longitudinally continuous feet at the bottom of the bevel mold, which is convenient for more stable placement during use.
[0026] The straight-edge mold 2 is an angle iron profile with an L-shaped cross-section, and a plurality of deep U-shaped holes are opened at fixed intervals on its vertical side. Reinforcing bars are inserted through the deep U-shaped holes during the casting of the component.
[0027] The bevel mold 1 and the straight-edge mold 2 are fixedly connected by welding; the vertical sides of the two straight-edge molds both face inwards.
[0028] As Figure 4 shown, after using this mold to produce a composite slab, the composite slabs are spliced, and the splicing seam is a multi-layer concave structure. When caulking is carried out later, the caulking material and the composite slab can be combined more stably.
[0029] The advantages of using this mold are as follows:
[0030] 1. Integrate the straight-edge mold and the bevel mold into one body, increasing the applicability of the mold; during the manufacturing process, when it is necessary to change the previous bevel composite slab to a straight-edge side composite slab, only need to change the side of the mold to complete the mold change; there is no need to replace the mold during production, reducing the material loss and labor hours increased by frequent mold changes required for producing different types of components.
[0031] 2. The bevel mold adopts a ribbed design, increasing the contact area between the new and old concretes, and forming a multi-layer concave structure to promote the stable combination of the later-stage caulking material and the composite slab; solving the problems of instability, easy cracking, and even falling off caused by caulking in the later stage of the project.
[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the above embodiments have been described in detail, those skilled in the art can still modify the technical solutions recorded in the above embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
