[0001] The utility model relates to the technical field of building equipment, in particular to a well-shaped beam floor support device and a well-shaped beam floor casting template device. Background Art

[0002] At present, the cross-beam floor supports used in construction sites generally use four vertical poles to support the upper formwork, and transfer the load downward through the vertical poles. This method consumes more materials, has complicated construction procedures, and has little available space. It cannot meet the requirements of efficient construction, green construction, and creating an economical construction site.

[0003] The floor structure of traditional buildings includes cast-in-place concrete floor slabs, and the upper and lower floor slabs are supported by vertical poles. In order to achieve safe and effective support, relatively dense vertical poles need to be set up, and the distance between the vertical poles cannot be too large, which is not conducive to forming a large open space in a low-cost manner. The installation of vertical poles and subsequent demolition work are also more labor-intensive.

[0004] That is to say, the prior art cross beam floor support device has the problems of using a large number of vertical poles, high cost, and small space under the floor. Utility Model Content

[0005] The utility model provides a well-shaped beam floor support device and a well-shaped beam floor casting template device to solve the above technical problems, which solves the problems of the well-shaped beam floor support device having a large number of vertical poles, high cost and small space under the floor.

[0006] The utility model provides a well-shaped beam floor support device, comprising: a vertical rod, which is extended along a first direction and installed on a connection part in a plate buckle system; and

[0007] A connecting device connected to one end of the vertical pole, the connecting device comprising a plurality of connecting arms arranged at intervals; and

[0008] The main keel is sleeved on the connecting arm and plug-connected with the connecting arm;

[0009] Wherein, the first top end surface of the main keel is coplanar with the second top end surface of the connecting device.

[0010] In one embodiment, the connecting device includes a regular polygonal prism having multiple peripheral walls, one end of multiple connecting arms is connected to the multiple peripheral walls one by one, and the vertical rod is connected to one end of the regular polygonal prism.

[0011] In one embodiment, the connecting arm is a cuboid, and the connection between the connecting arm and the corresponding peripheral wall forms a square, and each outer edge of the square has the same first perpendicular distance D1 as the outer edge of the adjacent peripheral wall.

[0012] In one embodiment, it also includes a plurality of wedges, which are connected end to end to form a square ring, which is arranged on the outer peripheral wall and sleeved on the connecting arm. The outer edge of the square ring and the outer edge of the adjacent outer peripheral wall have a second vertical distance D2, and the second vertical distance D2 is smaller than the first vertical distance D1. The wall thickness of the main keel is equal to the second vertical distance D2.

[0013] In one embodiment, the projection of the wedge on the first plane is a right-angled trapezoid, the right-angled side of the right-angled trapezoid is arranged on the connecting arm, and the bottom of the right-angled trapezoid is arranged on the outer peripheral wall surface.

[0014] In one embodiment, the regular polygonal prism is a cuboid, and the connecting arms are respectively arranged on the four outer peripheral wall surfaces of the regular polygonal prism.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the first top end surface of the main keel is coplanar with the second top end surface of the connecting device. In this way, the contact area between the secondary keel and the formwork located on the first top end surface and the second top end surface is larger. Thus, the stability of the cross-beam floor support device is increased. Moreover, in the present application, only a single vertical pole is provided, and the support of multiple main keels is achieved by providing a connecting device and multiple connecting arms thereon, thereby achieving multi-point support of the formwork. Thus, compared with the prior art, while increasing the support and bearing capacity of the cross-beam floor support device, the number of vertical poles provided is also reduced.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiment 1

[0032] like Figures 1 to 4 As shown, the utility model provides a crisscross beam floor support device 100.

[0033] The above-mentioned cross-beam floor support device 100 includes a vertical pole 10, a connecting device 20 and a main keel 30. The vertical pole 10 is extended along the first direction and installed at the connecting part of the buckle system; the connecting device 20 is connected to one end of the vertical pole 10, and the connecting device 20 includes a plurality of connecting arms 21 arranged at intervals; the main keel 30 is sleeved on the connecting arm 21 and plug-connected with the connecting arm 21; the first top end surface 31 of the main keel 30 is coplanar with the second top end surface 221 of the connecting device 20.

[0034] In the above arrangement, the first top end surface 31 of the main keel 30 is coplanar with the second top end surface 221 of the connecting device 20. In this way, the contact area between the secondary keel and the template located on the first top end surface 31 and the second top end surface 221 is relatively large.

Moreover, in the present application, only a single vertical pole 10 is provided, and the support of multiple main keels 30 is achieved by providing the connecting device 20 and the multiple connecting arms 21 thereon, thereby achieving multi-point support of the template. Thus, compared with the prior art, while increasing the support and bearing capacity of the cross-beam floor support device 100, the number of vertical poles 10 is also reduced. Thus, the use of vertical poles is reduced, the cost is saved, and the installation procedure of the vertical poles is reduced, while also increasing the space under the floor.

[0037] Specifically, in one embodiment, the slab support device 100 of the slab beam further comprises a plurality of wedges 40, which are connected end to end to form a square ring, which is arranged on the outer peripheral wall surface and sleeved on the connecting arm 21, and the outer edge of the square ring and the outer edge of the adjacent outer peripheral wall surface have a second vertical distance D2, the second vertical distance D2 is less than the first vertical distance D1, and the wall thickness of the main keel 30 is equal to the second vertical distance D2. In this way, it can be ensured that the outer edge of the main keel 30 is flush with the outer edge of the connecting arm 21, thereby beautifying the appearance of the slab beam support device 100. At the same time, the plurality of wedges 40 can be embedded in the gap between the main keel 30 and the connecting arm 21. Thereby, the overall connection strength of the slab beam support device 100 is enhanced, thereby improving its load-bearing stability and reliability.

[0038] Specifically, in one embodiment, the projection of the wedge 40 on the first plane (horizontal plane) is a right-angled trapezoid, the right-angled sides of the right-angled trapezoid are arranged on the connecting arm 21, and the bottom of the right-angled trapezoid is arranged on the outer peripheral wall surface.

[0046] The regular polygonal prism 22 is a regular hexagonal prism, and the connecting arms 21 are respectively disposed on six outer peripheral wall surfaces of the regular polygonal prism 22 .

[0047] The other structures of the third embodiment are the same as those of the first embodiment and will not be described again here.

[0049] Embodiment 4

[0050] like Figure 5 As shown, the utility model provides a casting template device for a slab of a well-shaped beam, which comprises the above-mentioned slab of a well-shaped beam support device 100, a secondary keel, a template and a buckle system. The secondary keel is set on the main keel 30 of the slab of a well-shaped beam support device 100; the template is set on the secondary keel; the buckle system has the slab of a well-shaped beam support device 100 installed on its connection part.

[0051] The above-mentioned cross beam floor support device 100 includes a vertical rod 10, a connecting device 20 and a main keel 30. Among them, the vertical rod 10, along the first direction ( Figure 5 The vertical direction) is extended in the vertical direction, and the vertical pole 10 is installed on the connection part of the buckle system; the connecting device 20 is connected to one end of the vertical pole 10, and the connecting device 20 includes a plurality of connecting arms 21 arranged at intervals; the main keel 30 is sleeved on the connecting arm 21 and plug-connected with the connecting arm 21; the first top end surface 31 of the main keel 30 is coplanar with the second top end surface 221 of the connecting device 20.

[0052] In the above arrangement, the first top end surface 31 of the main keel 30 is coplanar with the second top end surface 221 of the connecting device 20. In this way, the contact area between the secondary keel and the template located on the first top end surface 31 and the second top end surface 221 is relatively large. Thus, the stability of the cross-beam floor support device 100 is increased. Moreover, in the present application, only a single vertical pole 10 is provided, and the support of multiple main keels 30 is achieved by providing the connecting device 20 and the multiple connecting arms 21 thereon, thereby achieving multi-point support of the template. Thus, compared with the prior art, while increasing the support and bearing capacity of the cross-beam floor support device 100, the number of vertical poles 10 is also reduced. Thus, the use of vertical poles is reduced, the cost is saved, and the installation procedure of the vertical poles is reduced, while also increasing the space under the floor.

[0053] Specifically, Figures 1 to 3 As shown, in one embodiment, the connecting device 20 includes a regular polygonal prism 22 having multiple peripheral walls, one end of multiple connecting arms 21 is connected to the multiple peripheral walls one by one, and the vertical pole 10 is connected to one end of the regular polygonal prism 22.

[0054] Specifically, Figures 1 to 3 As shown, in one embodiment, the connecting arm 21 is a cuboid, and the connection between the connecting arm 21 and the corresponding peripheral wall forms a square, and each outer edge of the square is equal to the first vertical distance D1 of the outer edge of the adjacent peripheral wall.

[0055] Specifically, Figures 1 to 3 As shown, in one embodiment, the slab support device 100 of the slab beam further includes a plurality of wedges 40, which are connected end to end to form a square ring, which is arranged on the outer peripheral wall surface and sleeved on the connecting arm 21. The outer edge of the square ring and the outer edge of the adjacent outer peripheral wall surface have a second vertical distance D2, which is smaller than the first vertical distance D1, and the wall thickness of the main keel 30 is equal to the second vertical distance D2. In this way, it can be ensured that the outer edge of the main keel 30 is flush with the outer edge of the connecting arm 21, thereby beautifying the appearance of the slab support device 100 of the slab beam. At the same time, the plurality of wedges 40 can be embedded in the gap between the main keel 30 and the connecting arm 21. Thereby, the overall connection strength of the slab support device 100 of the slab beam is enhanced, thereby improving its load-bearing stability and reliability.

[0056] Specifically, Figures 1 to 3 As shown, in one embodiment, the projection of the wedge 40 on the first plane (horizontal plane) is a right-angled trapezoid, the right-angled sides of the right-angled trapezoid are arranged on the connecting arm 21, and the bottom of the right-angled trapezoid is arranged on the outer peripheral wall surface.

[0057] Specifically, Figures 1 to 3As shown, in one embodiment, the connecting arm 21 is made of solid square steel, and the main keel 30 is made of a rectangular tube that matches the solid square steel.

[0058] It should be noted that the connection device of the cross-shaped square steel is mainly made by the factory to cross and vertically connect the four solid square steel components of the main body, and the center part is also made solid to form a cross-shaped square steel as a whole. Then, four wedges are welded and installed at the four inner corners on the side of the center part and the four locations where the solid square steel is connected to each other. The four wedges are rectangular parallelepipeds of the same size and are used to fix and connect the main keel. Then a welded cover plate (regular polygonal prism) is installed on the top of the center of the cross-shaped square steel.

[0059] The connecting device is vertically connected to the vertical pole by welding at the center of the lower part of the device. The vertical pole is set to be cylindrical, which is consistent with the vertical pole of the common well-shaped beam floor template. The connecting device and the vertical pole together constitute a new type of supporting device. The supporting device is connected to the vertical pole hole of the lower buckle frame through the vertical pole.

[0060] The four main purlins are inserted into the four solid square steels in the connecting device in turn, and the main purlins are blocked and fixed by the cover plate and four wedges to ensure that the four main purlins are inserted into the connecting device to the same depth. At the same time, it also ensures that the top of the connecting device and the four main purlins are in the same plane and flush, which is more convenient for bearing the load together. The top plane is connected to support the well-shaped beam floor formwork through the four main purlins, bearing the load of the formwork and the secondary purlins. After that, the load borne by the main purlin is transferred downward to the vertical pole through the connecting device, and then the overall load is transferred to the buckle system below through the vertical pole.

[0061] The assembly process of the casting formwork device for the slab of the well-shaped beam is as follows: first, the connection device is prefabricated in the factory by welding and installing four solid square steels, cover plates and four wedges. Then the vertical poles are welded to form the top support device. Subsequently, four main keels are inserted to form the entire new slab of the well-shaped beam top support system. Then the disc buckle system is set up, and the new slab of the well-shaped beam top support device is installed at the connection part of the disc buckle system. Then the secondary keels and formwork are set up in turn on the upper part to complete the entire slab of the well-shaped beam formwork support system.
