Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to a floor formwork system without bottom support and a construction method thereof. Background Art

[0002] In the construction of narrow straight passages, if the traditional full-floor support formwork system is used for construction, due to the existence of bottom support, it will occupy a certain amount of ground space. In the case of limited space, it is not conducive to the transportation of materials in the passage. Sometimes it cannot even meet the requirements of the transport trolley moving inside, seriously affecting the construction progress and efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the problem that the bottom support of the existing support formwork system occupies the ground space, which is not conducive to the transportation of ground materials in a narrow construction space. A floor formwork system without bottom support and its construction method are provided, which can avoid occupying the ground space while meeting the construction requirements and facilitate the transportation of materials.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A floor formwork system without bottom support comprises pre-buried cone sleeve assemblies and height-adjustable wall-mounted supports arranged in pairs, a main beam, and a table formwork with a movable patching space in the middle. The main beam is detachably mounted at the bottom of the table formwork, the wall-mounted supports are located at the bottom of the main beam and symmetrically arranged on both sides of the main beam, and the pre-buried cone sleeve assemblies are mounted on the sides of the wall-mounted supports.

[0006] The present invention embeds pre-embedded cone sleeve assemblies in the walls on both sides, making them serve as supports for the entire formwork system. The pre-embedded cone sleeve assemblies are connected to wall-mounted supports, allowing the wall-mounted supports to attach to the wall and provide support. The wall-mounted supports then support the main beam, which is then supported by a table formwork. The width of the table formwork can be adjusted using the patching space in the middle of the table formwork, allowing both sides of the table formwork to fit the wall. The entire table formwork is installed in a straight, long channel, and concrete is poured from above the table formwork for construction. Compared to the prior art, which uses bottom supports to achieve overall load bearing, the present invention uses pre-embedded cone sleeve assemblies to support the walls on both sides, thereby omitting the bottom support. The floor formwork system can be constructed without occupying any ground space, and the entire straight, long channel can be used for material transportation, providing sufficient operating space for the transport trolley.

[0007] Furthermore, the table formwork comprises two supporting sections on either side and a central patching section, movably connected to the supporting sections. The patching section comprises two symmetrically arranged filler beams and wooden boards, one end of each filler beam connected to the supporting section and the other end cantilevered. The table formwork spans the tops of the two filler beams, with its upper surface flush with the upper surface of the supporting sections. The outer sides of the supporting sections are constructed in close contact with the wall to prevent concrete leakage from above the table formwork. The central patching section is flexible and can be adjusted to the width of the aisle being constructed, thereby adapting the width of the entire table formwork to the aisle.

[0008] Furthermore, the support portion includes a frame, a top plate, and multiple side plates. The side plates are mounted around the sides of the frame and are arranged around the frame, and the top plate is mounted on the top of the frame. The frame serves as an overall support, the top plate is used to receive concrete, and the side plates are attached to the wall to enhance the support performance of the support portion.

[0009] Furthermore, the wall-mounted support member includes a height-adjusting U-support, an adjusting nut, an adjusting screw, a support frame, and a pin, which are arranged in sequence from top to bottom. The adjusting screw is welded to the top of the support frame. An adjusting groove is provided in the middle of the adjusting screw. A slot is provided through the adjusting groove. The height-adjusting U-support is plugged into the adjusting groove. The adjusting nut is sleeved on the outside of the adjusting screw and is threadedly connected to the adjusting screw. The pin can pass through the slot and be plugged into the height-adjusting U-support. The adjusting nut is located at the bottom of the pin. The adjusting nut and the adjusting screw thread cooperate to realize the up and down adjustment of the height-adjusting U-support. The height-adjusting U-support is used to support the main beam, and the main beam supports the table formwork; the height-adjusting U-support cooperates with the adjusting screw to adjust the position of the height-adjusting U-support so that the height-adjusting U-support can move up and down. The adjusting nut is used to lock and fix the height-adjusting U-support after adjusting the position between the height-adjusting U-support and the adjusting screw. Specifically, the adjusting nut is used to limit the pin so that the pin cannot move downward, thereby fixing the position of the height-adjusting U-support; the support frame is used to cooperate with the embedded cone sleeve assembly to realize the installation and fixation of the wall-mounted support on the wall.

[0010] Furthermore, the embedded cone sleeve assembly includes an embedded plate equipped with a screw, a rotating cone sleeve, and a bolt. The rotating cone sleeve is plugged into the screw, and the bolt is also plugged into the rotating cone sleeve and threadedly connected thereto. The bolt is also connected to the side of the wall-mounted support. The embedded plate and rotating cone sleeve are both embedded in the wall. The bolt is used to connect the rotating cone sleeve to the support frame, thereby connecting the embedded cone sleeve assembly to the wall-mounted support.

[0011] Furthermore, the outer surface of the turnover cone sleeve is covered with a plastic sleeve. Preferably, the plastic sleeve is made of PVC material. The plastic sleeve is installed on the outermost layer of the turnover cone sleeve to prevent the concrete from directly contacting the outer surface of the turnover cone sleeve, while the embedded plate is permanently fixed to the concrete structure in the wall.

[0012] Furthermore, both sides of the table formwork are provided with anti-seepage rubber strips, which can seal between the two sides of the table formwork and the wall, thereby enhancing the anti-seepage effect of the concrete on the top.

[0013] The present invention also provides a construction method for a floor formwork system without bottom support, which is applied to the floor formwork system without bottom support as described above, and specifically comprises the following steps:

[0014] S1: Installing a vertical wall formwork, installing a pre-buried cone sleeve assembly on the wall formwork and passing it through, and pouring concrete;

[0015] S2: After the concrete reaches a certain strength, the wall formwork is removed, and a wall support is installed at the embedded cone sleeve assembly;

[0016] S3: Installing the main beam on the wall-attached support member;

[0017] S4: Laying a table formwork on the main beam and adjusting the movable patching space in the middle of the table formwork;

[0018] S5: After adjusting the flatness of the table formwork, tie the floor reinforcement and pour concrete.

[0019] The present invention obtains a wall by pouring concrete in a vertical wall formwork, and pre-buries a pre-embedded cone sleeve assembly in the wall. The pre-embedded cone sleeve assembly is connected to a wall-attached support member by using the pre-embedded cone sleeve assembly, and the wall-attached support member is installed and fixed to the wall. The main beam and a table formwork erected above the main beam are then supported and fixed, and then concrete is poured on the table formwork to carry out floor construction.

[0020] Furthermore, it also includes the disassembly of the formwork system, as follows:

[0021] S6: After the concrete reaches the required strength, the table formwork is sunk by knocking on the wall supports to separate it from the concrete surface. Then, the table formwork, main beam and wall supports are removed in sequence.

[0022] By adjusting the height of the wall supports, the table formwork can be lowered after construction is completed and then detached from the floor. The floor formwork system can then be disassembled according to the reverse operation during installation.

[0023] Furthermore, the overall construction process is divided into several sections, and any of the steps involved in wall formwork installation, floor formwork system installation without bottom supports, and floor reinforcement binding can be performed in different construction sections, allowing the floor formwork system without bottom supports to be quickly rotated and used. Because the passage is long, segmented construction is necessary. Different construction phases require different construction operations, some of which require the floor formwork system without bottom supports. Therefore, during construction operations that do not require the floor formwork system without bottom supports, the floor formwork system without bottom supports can be conveniently transferred to other construction phases where it is needed.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention's floor formwork system without bottom supports utilizes standardized, modular components, each installed via a quick-install, quick-lock mechanism. This significantly reduces the need for workers to repeatedly set up bottom supports, improving construction efficiency. Furthermore, for construction in narrow passageways, it eliminates the need to occupy ground space, thereby increasing ground space utilization. The present invention's construction method for the floor formwork system without bottom supports facilitates construction and allows for segmented construction, improving the system's turnover efficiency and shortening overall construction time.

[0039] Example 1

[0040] like Figures 1 to 6This embodiment is an embodiment of a floor formwork system without bottom support, including pre-embedded cone sleeve assemblies 1 and height-adjustable wall-mounted supports 2, main beams 3, and a table formwork 4 with a movable interlocking space in the middle. The main beams 3 are detachably mounted on the bottom of the table formwork 4, the wall-mounted supports 24 are located at the bottom of the main beams 3 and are symmetrically arranged on both sides of the main beams 3, and the pre-embedded cone sleeve assemblies 1 are mounted on the sides of the wall-mounted supports 24.

[0041] Furthermore, anti-seepage rubber strips 43 are provided on both sides of the table form 4 .

[0042] The embedded cone sleeve assembly 1 replaces the bottom support and is embedded in the side wall, fulfilling the function of a conventional bottom support. The embedded cone sleeve assembly 1 is connected to the wall-mounted support 2 to support the main beam 3 and the platform form 4. Concrete needs to be poured above the platform form 4 to construct the floor. A movable patch 42 is provided in the middle of the platform form 4 to accommodate pouring errors, allowing the sides of the platform form 4 to adapt to the width of the passage, thereby accommodating the construction of passages of different widths. An anti-seepage rubber strip 43 is provided to prevent concrete from leaking through the gap between the platform form 4 and the side wall during pouring.

[0043] Specifically, the table formwork 4 includes support parts 41 provided on both sides and an inlay part 42 located in the middle, which is movably connected to the support parts 41; the inlay part 42 includes two symmetrically arranged filling beams 421 and a wooden board 422, one end of the filling beam 421 is connected to the support part 41, and the other end is cantilevered. The template spans the top of the two filling beams 421 and its upper surface is flush with the upper surface of the support part 41.

[0044] Furthermore, the support portion 41 includes a frame 411 , a top plate 412 , and a plurality of side plates 413 . The side plates 413 are installed on the sides of the frame 411 and are arranged around the frame 411 . The top plate 412 is installed on the top of the frame 411 .

[0045] Frame 411 is welded from aluminum alloy secondary beams. Both top panel 412 and side panels 413 are constructed of plywood, secured together with rivets. The gaps around the plywood and frame 411 are sealed with filler glue. The short side panels 413 of frame 411 are equipped with convex structures 414, and both the long and short side panels 413 are provided with multiple pin holes. After the table formwork 4 is laid out to a specific size, the support portion 41 is a standard design, while the inlay portion 42 is a non-standard design. Together, the support portion 41 and the inlay portion 42 form the entire table formwork 4. The inlay beam 421 is connected to the support portion 41 with a locking pin, and a matching-sized wooden board 422 is used to lock the connection to the inlay beam 421.

[0046] Furthermore, a slide groove is provided at the bottom of the table form 4 , specifically at the bottom of the frame 411 , to facilitate cooperation with the main beam 3 .

[0047] Moreover, the wall-mounted support 2 includes a height-adjusting U-support 21, an adjusting nut 22, an adjusting screw 23, a support frame 24, and a pin 25, which are arranged in sequence from top to bottom. The adjusting screw 23 is welded to the top of the support frame 24. An adjusting groove 231 is provided in the middle of the adjusting screw 23. The adjusting groove 231 is penetrated by a slot. The height-adjusting U-support 21 is plugged into the adjusting groove 231. The adjusting nut 22 is sleeved on the outside of the adjusting screw 23 and is threadedly connected to the adjusting screw 23. The pin 25 can pass through the slot and be plugged into the height-adjusting U-support 21. The adjusting nut 22 is located at the bottom of the pin 25. The adjusting nut 22 and the adjusting screw 23 are threadedly matched to realize the up and down adjustment of the height-adjusting U-support 21. The support frame 24 is the main load-bearing weldment, which is welded from plates. A round hole is set on the back of the support frame 24, which is used in conjunction with the bolt 14 of the embedded cone sleeve assembly 1. The adjusting screw 23 is welded to the upper part of the support frame 24, and the adjustment is set in the middle of the groove screw. The screw height adjustment U support 21 is inserted into the adjusting screw 23. The height adjustment U support 21 is welded by an adjusting tube with equidistant through holes and a four-column U support. The adjusting screw 23 and the height adjustment U support 21 are penetrated by a pin 25. The pin 25 is provided with a semicircular groove. The adjusting nut 22 cooperates with the thread of the bolt 14 to realize the up and down adjustment of the height adjustment U support 21.

[0048] The embedded cone sleeve assembly 1 also includes an embedded plate 12 equipped with a screw 11, a rotating cone sleeve 13, and a bolt 14. The rotating cone sleeve 13 is plugged into the screw 11, and the bolt 14 is also plugged into the rotating cone sleeve 13 and threadedly connected thereto. The bolt 14 is also connected to the side of the wall-mounted support member 2. The screw 11 at the end of the embedded plate 12 is locked with the thread of the small surface of the rotating cone sleeve 13, and the thread of the bolt 14 is locked with the thread of the large surface of the rotating cone sleeve 13. The bolt 14 is also connected to the wall-mounted support member 2, thereby achieving the installation and fixation of the embedded cone sleeve assembly 1 and the wall-mounted support member 2.

[0049] Preferably, a plastic sleeve 15 is provided over the outer surface of the circular cone sleeve 13. The plastic is preferably made of PVC to prevent direct surface contact between the concrete and the circular cone sleeve 13. The embedded plate 12 is permanently fixed to the concrete structure, i.e., the side wall. The circular cone sleeve 13 and bolts 14 are removable components.

[0050] The main beam 3 is a rectangular, one-piece extruded aluminum alloy profile with anti-fall structures on both sides. This corresponds to the stop columns of the four-post U-bracket. The profile has a double groove at the top and a dovetail groove at the bottom, secured with T-bolts 14.

[0051] During construction, the wall-mounted supports 2 adjust the elevation of the table form 4. If the pre-embedded error is large, the height adjustment screws 23 can be aligned by adjusting the height adjustment U-brackets 21. The entire surface of the table form 4 can then be fine-tuned using the adjustment nuts 22. After the table form 4 is laid to a specified size, locking pins are inserted through the pin holes in the side panels 413 on the long sides of the table form 4. Windproof locks 423 securely connect the table form 4 to the main beam 3. The main beam 3 is then locked in place with the four-column U-brackets at the dovetail grooves using connecting bolts 14, connecting all components into a single unit and providing windproof protection.

[0052] Example 2

[0053] like Figures 7 to 9 As shown, this embodiment is an embodiment of a construction method of a floor formwork system without bottom support, which is applied to the floor formwork system without bottom support as described above, and specifically includes the following steps:

[0054] S1: Install the vertical wall formwork, install the embedded cone sleeve assembly 1 on the wall formwork and set it through, and pour concrete;

[0055] S2: After the concrete reaches the required strength, the wall formwork is removed and the wall support 2 is installed at the embedded cone sleeve assembly 1;

[0056] S3: Install the main beam 3 on the wall support 2;

[0057] Specifically, the main beam 3 is matched with the height-adjusting U-bracket 21 on the wall support 2 and is fastened with T-bolts 14;

[0058] S4: Lay the table formwork 4 on the main beam 3 and adjust the movable patching space in the middle of the table formwork 4;

[0059] Furthermore, the main beam 3 and the slide groove provided at the bottom of the table form 4 are precisely positioned, and the sides of the table form 4 are fitted to the concrete structure. The anti-seepage rubber strips 43 are used for sealing to prevent leakage. After the support part 41 of the table form 4 is laid, the non-standard position in the middle is filled with the filling part 42. Specifically, the filling is sealed with a filling beam 421 and a wooden board 422, and locked with pins.

[0060] The table formwork 4 can be installed in a foolproof manner by providing a convex structure 414 on the short side of the frame 411, which cooperates with the double grooves on the top of the main beam 3, and has an automatic alignment function, so that installation can be completed without the need for measuring tools.

[0061] S5: After adjusting the flatness of the table formwork 4, tie the floor reinforcement and pour concrete.

[0062] After adjusting the flatness of the table formwork 4 by the adjusting nut 22 on the wall support 2, the floor reinforcement is tied and concrete is poured.

[0063] Furthermore, it also includes the disassembly of the formwork system, as follows:

[0064] S6: After the concrete reaches the required strength, the table formwork 4 is sunk by knocking the wall support 2, so that the table formwork 4 is separated from the concrete surface, and then the table formwork 4, the main beam 3, and the wall support 2 are removed in sequence.

[0065] After the floor is poured with concrete, the formwork system forms a tight fit with the concrete structure. At the same time, the unloading latch 25 is struck to change the contact position between the adjusting screw 23 and the latch 25. The force point is transferred from the main body of the latch 25 to the semicircular groove of the latch 25, so that the table form 4 descends by its own weight. The table form 4 and the concrete structure surface are no longer in a tight fit. By rotating the adjusting nut 22, the table form 4 is lowered until there is enough space to remove all components.

[0066] Example 3

[0067] This embodiment is another embodiment of a construction method for a floor formwork system without bottom support. This embodiment is similar to Example 2, except that the overall construction is divided into several sections. Any step of installing wall formwork, installing the floor formwork system without bottom support, and binding floor steel bars can be performed in different construction sections, so that the floor formwork system without bottom support can be quickly turned around and used.

[0068] Since the passage is long, it needs to be constructed in sections. In different construction stages, the construction operations are different. Some of the construction operations require the use of a floor formwork system without bottom support. Therefore, in the construction operations that do not require the floor formwork system without bottom support, it is beneficial to transfer the floor formwork system without bottom support to other construction stages where it is needed.

[0069] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
