Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of formwork construction, in particular to an early-dismantling support structure and a laterally dismountable formwork support system. BACKGROUND

[0002] In the formwork construction process of the main structure of a building, the most commonly used support frame and formwork in China can be divided into three categories: the first category is a fastener type steel pipe scaffold with wooden formwork, the second category is a socket type disc fastener steel pipe scaffold with wooden formwork, and the third category is an aluminum alloy formwork system.

[0003] The fastener type scaffold and the disc fastener type scaffold are truss structures, which require multiple horizontal rods and diagonal bracing rods to be set to ensure the overall stability of the frame, but this will greatly increase the workload of setting up the frame and block the space below the frame, which hinders construction work and management; if early dismantling of the wooden formwork is to be achieved, the two types of frames need to be matched with adjustable jacks, which can adjust the height of the main beam and the secondary beam through threads, so that the wooden formwork can be separated from the frame and early dismantling can be achieved. Since the height of all adjustable jacks needs to be adjusted in sequence, the efficiency of early dismantling achieved through this component is relatively low.

[0004] In the aluminum alloy formwork system, the aluminum formwork itself can bear the concrete material and construction load, so the horizontal rods can be greatly simplified, thus forming an open lower space. At the same time, the early dismantling node of the clamping plate type can quickly complete the early dismantling operation by removing the pins. However, the early dismantling node is in the shape of a "one", which can only connect the main beam in a single direction, which is not conducive to the formation of an upper rigid layer of the frame, and the safety of the frame is reduced. At the same time, the aluminum alloy formwork has many non-standard parts, low reuse rate, high amortization cost, and its weight is heavier than that of traditional wooden formwork, making it difficult to transport and handle during construction.

[0005] At the same time, in the prior art, when the formwork is early dismantled, the early dismantling head is usually controlled to descend to achieve the descent of the backrest assembly, so that the formwork supported by the backrest assembly is early dismantled. When the early dismantling head on one side of the backrest assembly is lowered and the early dismantling head on the other side is not lowered, the backrest assembly can only be connected to the early dismantling head that is lowered to form a cantilever member, which has the risk of falling of the backrest assembly and poses a safety risk. SUMMARY

[0006] The technical problem to be solved by the present application is to provide an early dismantling support structure and a laterally dismountable formwork support system. The solution adopted by the present application to solve the technical problem is: An early dismantling support structure, used in cooperation with a backrest assembly, comprises an early dismantling head and a vertical telescopic support connected to the early dismantling head.

In the middle span part, the two ends of the main beam piece in the backrest assembly are respectively connected with the two adjacent support assemblies through the clamping pieces on the side close to each other, and the inverted eight-shaped arrangement facilitates the separation of the backrest assembly and the early dismantling head, so that the early dismantling head will not descend during the whole dismantling process, and the supporting surface for the floor is also improved, so that the support is more stable and reliable.

[0007] In some possible embodiments, in order to effectively realize the connection of the support assembly and the vertical telescopic support and enable the position adjustment of the support assembly in the horizontal direction, the support assembly comprises a support head in cross shape, and a sleeve with an axis on the same straight line as the center of the support head and fitted with the vertical telescopic support; the sleeve is located at the bottom of the support head and is integrally formed with the support head.

[0008] In some possible embodiments, in order to effectively realize the connection of the support head and the backrest assembly through the clamping piece, the clamping piece is four groups and is used in cooperation with the early dismantling head; the clamping piece is four groups and is installed on the outer side of the support head; each group of the clamping piece comprises two groups of clamping plates connected with each other at one end and forming an L-shaped structure, and the two adjacent groups of clamping pieces form a clamping cavity for clamping the backrest assembly; the four groups of clamping cavities formed by the four groups of clamping pieces are in cross shape.

[0009] In some possible embodiments, grooves for installing the clamping plates are arranged on the outer side of the support head; the two groups of clamping plates in each group of clamping pieces are respectively connected with the backrest assembly through the locking piece at the end away from each other and passing through the corresponding grooves.

[0010] In some possible embodiments, in order to effectively control the position of the early dismantling head according to the floor height through the vertical telescopic support, the vertical telescopic support comprises an inner rod sleeved in the early dismantling head, an outer rod sleeved on the outer side of the inner rod and vertically telescopic with the inner rod, and a locking limiting piece for locking the outer rod and the inner rod.

[0011] A side dismantling plate mold support system comprises a backrest assembly for supporting the plate mold, and an early dismantling support structure as described above connected with the backrest assembly.

[0012] In some possible implementation manners, the back bracing assembly comprises a main beam connected with two adjacent support assemblies, and a secondary beam for connecting two parallel main beams; the top surface of the main beam is coplanar with the top surface of the support assembly; the formwork is a wooden formwork or a plastic formwork, which is installed on the secondary beam and coplanar with the top surface of the support assembly. The main beam is provided with an inclined surface I at one end close to the support assembly, which is in contact with the support assembly; and the main beam is provided with embedded grooves for installing clamps on both sides along the length direction of the main beam.

[0013] In some possible implementation manners, the side support structure for supporting the secondary beam is arranged on both sides of the main beam along the length direction of the main beam.

[0014] In some possible implementation manners, the side support structure is in L shape, comprising a vertical plate arranged vertically and connected with one side of the main beam, and a bottom plate connected with the bottom of the vertical plate and installed on the side of the main beam; the secondary beam is installed on the bottom plate and connected with the vertical plate.

The gasket with a flat top surface is installed on the bottom plate and connected with the bottom plate through a pin; the main beam installed on the bottom plate is located between the pin and the vertical plate; the bottom surface of the gasket is arranged obliquely and in contact with the top surface of the bottom plate.

[0016] Compared with the prior art, the present application has the following advantages: The main beam and the secondary beam of the present application do not have horizontal bars below, and the span between the two vertical telescopic supports can be up to 1.8 m, so the lower passing width is greatly increased, and the passing convenience is greatly improved. During the installation process, only 8 sets of locking pieces are needed to connect one mid-span frame unit, so the installation operation is greatly simplified; when early disassembly is needed, the height of any component does not need to be adjusted, and the early disassembly can be completed by removing only 8 sets of locking pieces, so the disassembly process is simple; the installation and disassembly speed of the formed frame is greatly improved compared with the traditional frame. The support structure in the present application is suitable for cast-in-place concrete floor and also suitable for prefabricated assembly type composite floor. The length-adjustable main beam and secondary beam are used in cooperation with the vertical telescopic support with adjustable height, which can be applied to different floor heights and different area formwork engineering; at the same time, the support structure can be used in cooperation with wooden formwork or plastic formwork.

[0042] For the prefabricated assembly type composite floor slab, the installation process is basically the same as that of the cast-in-place reinforced concrete floor slab, but only the secondary beam member 32 and the plate mold 30 are installed at the cast-in-place slab belt, and the secondary beam member 32 and the plate mold 30 can not be installed in the coverage area of the composite slab. The composite slab can be directly placed on the main beam member 31; for the prefabricated assembly type composite floor slab, the disassembly process is the same as that of the cast-in-place reinforced concrete floor slab.

[0043] The present application is not limited to the foregoing specific embodiments. The present application extends to any novel feature or any new combination described in this specification, and any novel method or process step or any new combination disclosed.
