Description

Technical Field

[0001] The present application belongs to the field of construction engineering, and specifically relates to a modular floor structure and a basement formwork system composed of the modular floor structure. Background Art

[0002] Concrete formwork and support refer to the formwork for newly poured concrete and the support system for supporting the formwork. According to the different types of formwork materials, commonly used formworks mainly include wooden formwork, aluminum formwork, composite steel formwork, plastic formwork, silicon ink selenium non-disassembly formwork and other new formworks. As for common formworks, wooden formworks have become the most widely used formwork in ordinary housing construction projects due to their relatively low construction cost, strong applicability to special-shaped components or non-standard components, light weight per unit area, and convenient and flexible use.

[0003] However, the existing wooden formwork system has the following disadvantages in use: The turnover rate of the formwork is low and the consumption of wood is high. Compared with the combination steel formwork, aluminum formwork, plastic formwork, etc., which can be turned over dozens or even hundreds of times, the turnover rate of wooden formwork in ordinary housing construction projects is generally between 4 and 15 times due to the need for multiple binding, dismantling and cutting. The turnover rate is low, resulting in high consumption of wood.

[0004] The degree of mechanization is low and the labor consumption is high. The construction processes such as the transportation of formwork scaffolding materials, the erection of brackets, the installation of formwork, the processing of nodes, the reinforcement of formwork, and the removal of brackets are all done manually. The whole operation process is cumbersome and requires a lot of labor.

[0005] 3. There are many dangerous operations during the construction process. The process of erecting the formwork support and installing the beam formwork involves long-term high-altitude operations, which increases the potential safety hazards of construction.

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, a modular floor structure is provided, including a column formwork structure 10 arranged at four corners, a beam formwork structure 20 is arranged between two adjacent column formwork structures 10, and a floor structure 30 is arranged between the beam formwork structures 20. The floor structure 30 is spliced ​​by a plurality of floor units 31, and a jacking structure 40 is arranged between two adjacent floor units 31. The floor structure 30 spliced ​​by the plurality of floor units 31 and the beam formwork structure 20 can be spliced ​​to form a basement floor template of any size.

[0030] In the formwork system of construction projects, a complete formwork system is inseparable from the column formwork structure 10, the beam formwork structure 20 and the floor structure 30. Taking a square formwork system unit as an example, the four column formwork structures 10 are arranged in a square, and two adjacent column formwork structures 10 are connected by a beam formwork structure 20, and a floor structure 30 is located between the four beam formwork structures 20.

[0031] Among the existing formwork structures, the floor structure 30 has the largest formwork area, the most formwork cutting, the longest construction time, the highest risk factor, and the most serious consumables, so this application will make improvements to this pain point.

[0032] like Figure 2As shown, the floor slab unit 31 includes a square wooden panel 311 and a steel bar truss 312 installed under the panel 311. Edge sealing structures 313 are provided at the four corners of the truss 312. The edge sealing structure 313 is formed by splicing two steel plates into a right angle shape. The length * width of the panel 311 is 900 cm * 900 cm.

[0033] As Figures 2 to 4 shown, the truss 312 includes a lower chord 3121 and an upper chord 3122 arranged above the lower chord 3121. There are a pair of upper chords 3122, which are symmetrically distributed with the lower chord 3121 as the center. The upper chord 3122 and the lower chord 3121 are connected by diagonal web members 3123. The diagonal web members 3123 are connected to the upper chord 3122 and the lower chord 3121 in a triangular manner. The purpose is to form a stable triangular system to increase the overall structural performance of the truss 312. At the same time, after the truss 312 is connected to the panel 311, when viewed laterally, a triangular stable system is formed between the upper chord 3122, the lower chord 3121, the diagonal web members 3123 and the panel 311. Such a multiple triangular system greatly improves the bearing capacity of the entire truss 312, making the floor slab unit 31 not easily bent or deformed when pouring concrete.

[0034] The lower chord 3121 is a through rod of the entire truss 312. By passing through the edge sealing structure 313, an interface 314 is formed between the two steel plates of the edge sealing structure 313, and the jacking structure 40 is spliced with the interface 314.

[0035] As Figures 5 and 6 shown, the beam formwork structure 20 includes a beam bottom plate 21, a first beam side plate 22 and a second beam side plate 23 respectively installed on the beam bottom plate 21. A first flange plate 24 is vertically installed on the first beam side plate 22, and a second flange plate 25 is vertically installed on the second beam side plate 23. The entire structural end face forms a "U" shape; Beam back ribs 26 are evenly distributed on the outer sides of the beam bottom plate 21, the first beam side plate 22 and the second beam side plate 23; Flange back ribs 27 are evenly arranged under the first flange plate 24 and the second flange plate 25; The beam formwork structure 20 is spliced with the floor slab unit 31 through the first flange plate 24.

[0036] As Figure 7 and Figure 8 shown, the jacking structure 40 includes a screw rod 41, a support plate 42 arranged on the screw rod 41, a jacking plate 43 arranged on the support plate 42, and a pin 44 arranged on the support plate 42; The pin 44 is connected to the truss 312 to support the floor slab unit 31; The four corners of the jacking plate 43 are spliced with the interfaces 314 of adjacent floor slab units 31.

[0037] Of course, depending on the different assembly positions, when the top supporting structure 40 is set between the central floor units, a four-joint top supporting structure is selected. At this time, the four corners of the top supporting plate 43 are just completely spliced ​​with the interfaces 314 of the four adjacent floor units to form a plane; if the top supporting plate 43 is set at the edge of the entire basement floor formwork, a double-joint top supporting structure is selected. At this time, only two corners of the top supporting plate 43 are spliced ​​with the interfaces 314 of the two adjacent floor units to form a plane, and the surfaces where the other two corners are located are spliced ​​with the first flange plate 24 of the beam formwork structure 20 to form a plane; if the top supporting plate is set at the four corners of the entire basement floor formwork, a single-joint top supporting structure is selected. At this time, only one corner of the top supporting plate 43 is spliced ​​with the interface 314 of the adjacent floor unit to form a plane, and the surfaces where the other three corners are located are spliced ​​with the first flange plate 24 of the beam formwork structure 20 to form a plane (see Figure 2 The top supporting plate 43 is threadedly connected to the screw rod 41, so that the top supporting plate 43 can be adjusted to be flush with the panel 311.

[0038] like Fig. 9 As shown, the present application realizes the connection structure between multiple floor units 31 and between the floor units 31 and the first flange plate 24 by splicing the floor structure 30 and the beam formwork structure 20, and realizes the connection structure between multiple floor units 31 and the first flange plate 24 through the top supporting structure 40. By adopting this splicing method, the pre-assembly of basement floor formwork of any size can be realized.

[0039] Assembly method of modular floor structure in this application: First, design the basement according to the size of the basement to be constructed. Figure 2 When designing the basement formwork system shown, the maximum number of floor units 31 is calculated, and the area that cannot constitute a complete floor unit is supplemented by a beam formwork structure. Specifically, it is adjusted by designing a reasonable width of the first flange plate 24 and the second flange plate 25 (of course, if one side of the beam formwork structure is a wall, the second flange plate 25 can be omitted).

[0040] Secondly, if Fig.10 As shown, several floor units 31 are spliced ​​in sequence through the top supporting structure 40. During the splicing, the pins 44 of the top supporting structure 40 are connected to the trusses 312, and the top supporting plates 43 are spliced ​​with the interfaces 314 at the four corners of the floor units, so that the panel layer forms a continuous plane, and the trusses 312 of all the individual floor units 31 form a continuous truss system located at the panel layer.

[0041] Finally, after all the floor units 31 are spliced, the four sides of the panel layer are connected to the beam formwork structure 20, and the first flange plate 24 of the beam formwork structure 20 is directly connected to the panel layer through the top supporting structure 40, so that the size of the entire panel layer meets the design size of the basement panel.

[0042] The system composed of modular floor structures assembled by the above-mentioned assembly method can be transported to the construction site for template installation and subsequent construction work.

[0043] like Fig.10 As shown, a foldable beam under-mounted quick-install support frame 50 is provided, which is arranged Figure 1 The middle beam mold structure 20 is composed of a plurality of continuously foldable bracket units, each bracket unit including a first folding frame 501, a second folding frame 502 cross-intersecting the first folding frame 501, single vertical poles 503 arranged at both ends of the first folding frame 501 and below both ends of the second folding frame 502, a cross bar assembly 504 arranged between the single vertical poles, and a sleeve top screw 505 arranged on the first folding frame 501.

[0044] like Figure 11 to Figure 12 As shown, the first folding frame 501 is made of an I-shaped steel plate, including a horizontal plate 5011, which is placed upright, and a first crossbar 5012 is arranged on the upper edge of the horizontal plate 5011, and a groove 5013 is opened in the center of the first crossbar 5012, and the depth of the groove 5013 is equal to the height of the second folding frame 502, and a rotating shaft 5014 is arranged in the center of the groove 5013. A first single-pole sleeve 5015 and a V-shaped structure composed of two extension plates 5016 are arranged at the left and right ends of the horizontal plate 5011, and the V-shaped structure composed of the extension plates 5016 wraps the first single-pole sleeve 5015, and the V-shaped opening is extended to the plate surface of the horizontal plate 5011 for fixing, and a top screw sleeve 5017 is arranged on the outer side of the V-shaped end, and a latch member is arranged on the cylinder of the top screw sleeve 5017.

[0045] like Fig.13 As shown, the second folding frame 502 is made of an I-beam steel plate, including a second cross bar 5021. The middle section of the second cross bar 5021 is an inclined bar 5022 with an angle of 17°. A rotating shaft sleeve 5023 is arranged at the center of the inclined bar 5022. A second single-rod sleeve 5024 is arranged at each end of the second cross bar 5021. The angle between the inclined bar 5022 and the horizontal plane ranges from 15° to 25°. 17° is a preferred angle of this embodiment, and it is not excluded that the inclined bar 5022 can also be set to other angles in actual application of this application.

[0046] like Fig.14 As shown, the single vertical rod 503 is a telescopic rod composed of two or more sections of rod bodies 5031 , and a disc 5032 is respectively provided at the upper end and the lower end of the rod body 5031 .

[0047] like Figure 15 to Figure 16As shown, there are two groups of crossbar assemblies 504, one of which is installed in the middle section of the single pole 503, and the other is set at the bottom section of the single pole 503, to provide strength for the entire support frame. Of course, according to engineering needs, any other number of crossbar assemblies can also be designed. At the same time, the crossbar assembly 504 cooperates with the single pole 503 to fold or unfold in conjunction with the first folding frame 501 and the second folding frame 502.

[0048] The cross bar assembly 504 includes a first rotating rod 5041 and a second rotating rod 5042 arranged below the first rotating rod 5041. A third sleeve 5043 is arranged at the center of the first rotating rod 5041, and a sleeve extension section 50431 is provided on the lower surface of the third sleeve 5043; a third sleeve 5043 is also arranged at the center of the second rotating rod 5042, and the sleeve extension section 50431 of the first rotating rod 5041 is sleeved into the third sleeve 5043 at the center of the second rotating rod 5042, thereby realizing the rotational connection between the first rotating rod 5041 and the second rotating rod 5042.

[0049] Both ends of the first rotating rod 5041 and the second rotating rod 5042 are provided with a semicircular first arc cover plate 5044, and the first arc cover plate 5044 includes a second arc cover plate 5045. After the first arc cover plate 5044 and the second arc cover plate 5045 are assembled, they form a sleeve shape and can be mounted on the outer diameter of the single vertical rod 503.

[0050] The foldable quick-install support frame under the beam of the present application is assembled in the following manner before construction: The rotating shaft sleeve 5023 of the second folding frame 502 is sleeved on the rotating shaft 5014 of the first folding frame 501. At this time, the inclined rod 5022 of the second folding frame 502 is just located in the groove 5013 of the first folding frame 501 and can rotate in the groove 5013. Insert the sleeve top screw 505 into the top screw sleeve 5017 and lock the position through the latch member. Take two single poles 503 and insert them into the first single pole sleeves 5015 at both ends of the first folding frame 501 respectively, and take two single poles 503 and insert them into the second single pole sleeves 5024 at both ends of the second folding frame 502 respectively. Take two groups of crossbar assemblies 504, one group is set at the middle section of the single upright pole 503, and the other group is set at the bottom section of the single upright pole 503. Each group of crossbar assemblies 504 includes a first rotating rod 5041 and a second rotating rod 5042. The semicircular first arc cover plates 5044 at both ends of the first rotating rod 5041 fit with the two single upright poles 503 under the first folding frame 501, and the single upright pole 503 is wrapped and fixed by the sleeve shape formed by connecting the second arc cover plate 5045 and the first arc cover plate 5044. Similarly, the sleeve extension section 50431 of the first rotating rod 5041 is connected to the sleeve extension section 50432 of the first rotating rod 5041. The third sleeve 5043 is inserted into the center of the second rotating rod 5042, and the semicircular first arc cover plates 5044 at both ends of the second rotating rod 5042 fit with the two single upright poles 503 under the second folding frame 502, and the single upright poles 503 are wrapped and fixed by the sleeve shape formed by the second arc cover plate 5045 connected with the first arc cover plate 5044; at this time, the first rotating rod 5041 and the second rotating rod 5042 rotate to intersect, and can rotate at the same angle as the first folding frame 501 and the second folding frame 502 at the same time, so as to realize the linked folding or unfolding of the entire frame structure.

[0051] The disc 5032 at the upper section of the single pole 503 can prevent the first folding frame 501 and the second folding frame 502 and the upper structure from accidentally sliding down, and the disc 5032 at the bottom section of the single pole 503 can prevent the cross bar assembly 504 from accidentally sliding down, providing support and protection for the entire support frame both during the erection process and during use.

[0052] According to the on-site construction size requirements, multiple bracket units are assembled in the same manner as described above. In the process of continuous construction, except for the outermost ends of the second folding frames 502 at both ends of the support frame (see Fig.10 The second pole sleeves 5024 at both ends of the second folding frame 502 are directly connected to the single pole 503, and the second pole sleeves 5024 at both ends of the other second folding frames 502 are sequentially mounted on the upper ends of the first single pole sleeves 5015 at both ends of the adjacent first folding frame 501 (see Fig.10 ), the first rotating rod 5041 and the second rotating rod 5042 are correspondingly set up between the front and rear bracket units, thereby realizing the rotation connection between all the first folding frames 501 and the second folding frames 502.

[0053] This application can be set up through the above method Fig.10 The foldable under-beam quick-install support frame shown can be folded or extended in the horizontal direction.

[0054] like Fig.17 As shown, when in use, the pre-assembled modular floor structure is transported to the construction site. At the same time, four sets of foldable beam-under-fast installation and removal support frames 50 are also manufactured in advance according to the size of the beam formwork structure 20 at the construction site and transported to the site. The staff pulls open the entire frame from one end of each set of foldable beam-under-fast installation and removal support frames in turn, so that the sleeve top screw 505 fits tightly with the beam formwork structure 20, and arranges the support frames on the four sides of the modular floor structure. At this point, the entire basement formwork system is completed.

[0055] After use, the modular floor structure can be quickly dismantled into a single floor unit on site, and the support frame can also be folded and retracted on site. Compared with the traditional on-site loose assembly, the construction site floor structure and beam support system of this application have shown remarkable efficiency in the erection and dismantling process. This efficiency is not only reflected in the speed of erection and dismantling, which can greatly shorten the construction time and improve construction efficiency; it is also reflected in the convenience of operation.
