[0021] Example 1 See also Figures 2 to 5 The pluggable support embedded component includes a support embedded part 1 whose bottom is embedded in the cast-in-place concrete floor 8, and an inverted U-shaped plug 2 is provided on the support embedded part 1. The support embedded part 1 is provided with a hollow hole that matches the two legs of the U-shaped plug 2. The depth of the hollow hole is limited to ensure that the support embedded part 1 and the U-shaped plug 2 will not be separated during construction. The bottom fork of the oblique adjustment support rod 5 is against and fixed to the U-shaped plug 2, and the end of the horizontal adjustment support rod 6 is hingedly connected to the middle of the U-shaped plug 2.

The inserted support embedded part 1 is provided with a socket that matches the corresponding locking pins 3. The socket is cross-connected and connected with the hollow hole. The ends of the two legs of the U-shaped plug 2 are provided with pin holes 2.2. The two locking pins 3 are respectively inserted into the pin holes 2.2 of the corresponding legs of the U-shaped plug 2. The U-shaped plug 2 and the two locking pins 3 form a locking structure.

[0023] See also Figures 6 to 8 The two legs of the U-shaped plug 2 are respectively provided with sealing rings 4 that are tightly matched with the hollow hole and the corresponding legs. Each locking pin 3 is provided with a sealing ring 4 that is tightly matched with the plug hole and the locking pin 3. In one or more embodiments, the sealing ring 4 is a truncated cone structure as a whole, and a convex ring is provided at the end with a larger opening of the truncated cone structure.

[0024] When tool-type formworks 10 such as aluminum alloy formworks 10 are used as formworks 10 for cast-in-place concrete construction in the cast-in-place concrete process of frame-shear structure buildings, when erecting vertical tool-type formworks 7 such as shear walls and columns, it is necessary to use horizontally adjustable support rods 6 and obliquely adjustable support rods 5 to adjust the positioning of the vertical tool-type formworks 7 on the cast-in-place concrete slab 8 and the verticality of the vertical tool-type formworks 7 itself. When working, the horizontally adjustable support rods 6 and the obliquely adjustable support rods 5 need to pre-embed a supporting fixing point on the cast-in-place concrete slab 8, and the supporting fixing point needs to be pre-embedded before pouring concrete on the cast-in-place concrete slab 8.

[0025] According to the working requirements of the embedded support fixing point, the present invention designs a pluggable embedded support assembly as the support point of the horizontal adjustment support rod 6 and the oblique adjustment support rod 5 on the cast-in-place concrete floor 8. The pluggable embedded support assembly consists of a support embedded part 1, a sealing ring 4, a U-shaped plug 2 and a locking pin 3. Before embedding, the sealing ring 4 is respectively put on the U-shaped plug 2 and the locking pin 3, and then the U-shaped plug 2 is inserted into the hollow hole matching with it in the embedded support part 1, and then the thinner end of the locking pin 3 is inserted into the plug hole, ensuring that the thinner end of the locking pin 3 can be inserted into the pin hole 2.2 of the U-shaped plug 2, so that the U-shaped plug 2 cannot be withdrawn from the embedded support part 1, and finally the sealing ring 4 is adjusted so that the sealing ring 4 completely seals the gap between the U-shaped plug 2 and the hollow hole and between the locking pin 3 and the plug hole of the embedded support part 1, so as to prevent cement slurry from flowing in during the cast-in-place concrete construction. The organized pluggable support embedded components are installed according to the required support fixing point positions of the horizontally adjustable support rods 6 and the obliquely adjustable support rods 5, according to the longitudinal and transverse arrangement of the floor slab steel bars 9 in the cast-in-place concrete floor slab 8, at the intersection nodes around the longitudinal and transverse floor slab steel bars 9, in a placement direction that is compatible with the longitudinal steel bar grooves 1.2 and transverse steel bar grooves 1.3 on the support embedded parts 1, and the longitudinal and transverse floor slab steel bars 9 are tied and fixed to the pluggable support embedded components with tying wires through the tying rings 1.4 on the support embedded parts 1, and then the cast-in-place concrete floor slab 8 can be poured. After the concrete pouring of vertical components such as shear walls and columns is completed and the horizontal adjustment support rod 6, the oblique adjustment support rod 5 and the vertical tool formwork 7 are removed, the locking pin 3 with the ring end can be used to first pull out the locking pin 3 from the supporting embedded part 1, and then the U-shaped plug 2 can be removed from the supporting embedded part 1, and the supporting embedded part 1 remains in the concrete; if the sealing ring 4 is not damaged, it can be reused together with the U-shaped plug 2 and the locking pin 3, and replaced with a new one if it is damaged; the hollow part of the supporting embedded part 1 with the U-shaped plug 2 and the locking pin 3 removed can be filled with cement slurry.

[0026] Example 2 This embodiment is basically the same as Embodiment 1, except that: See also Figures 9 to 13 The supporting embedded part 1 includes a base 1.5, on which two parallel right-angle fork arms are arranged, each right-angle fork arm includes a first arm 1.6 connected to the U-shaped plug 2 legs and a second arm 1.7 connected to the locking pin 3, the first arm 1.6 is connected to the U-shaped plug 2 legs through a hollow hole, and the second arm 1.7 is connected to the locking pin 3 through a plug hole. In one or more embodiments, the first arm 1.6 and the second arm 1.7 are both at an angle of 45° with the horizontal plane.

[0027] The cast-in-place concrete floor 8 is provided with floor reinforcement bars 9 arranged in a criss-cross pattern. The supporting embedded parts 1 include two parallel bases 1.5, each base 1.5 is respectively connected to a right-angle fork arm.

In one or more embodiments, each longitudinal reinforcement groove 1.2 and transverse reinforcement groove 1.3 are provided with a binding ring 1.4.

[0028] The longitudinal steel bar grooves 1.2 on the same side of the two bases 1.5 are higher than the longitudinal steel bar grooves 1.2 on the other side, and each base 1.5 is provided with two transverse steel bar grooves 1.3, wherein the transverse steel bar grooves 1.3 near the end are lower than the transverse steel bar grooves 1.3 near the first arm 1.6, and the transverse steel bar grooves 1.3 corresponding to the positions of the two bases 1.5 are equal in height. Each base 1.5 is provided with an arched notch opening downward at the bottom.

[0029] See also Figures 14 to 16 Each leg of the U-shaped plug 2 includes two sections, one section is an inclined structure 2.3 connected to the first arm 1.6, the pin hole 2.2 is located at the bottom of the inclined structure 2.3, and the other section is a vertical structure 2.4, and the vertical structure 2.4 is provided with a pin ear 2.1 connected to the horizontal adjustment support rod 6 through a pin shaft 6.1, see Figures 17 to 20 The locking pin 3 has a ring at one end and a variable-section round rod at the other end. The thin end of the variable-section round rod of the locking pin 3 is inserted into the pin hole 2.2, and the end of the variable-section round rod of the locking pin 3 is truncated cone-shaped.

[0030] Support embedded part 1 Support embedded part 1 is composed of two monomers with the same structure connected into a whole by connecting rod 1.1. The spacing between the two monomers connected by connecting rod 1.1 matches the spacing of the openings of U-shaped plug 2. The opening spacing of U-shaped plug 2 meets the support force and operation requirements of horizontal adjustment support rod 6 and oblique adjustment support rod 5. The shape of the monomer of support embedded part 1 is shown in the structural diagram. The upper part is composed of two first arms 1.6 and second arms 1.7 that cross at 90 degrees. The first arms 1.6 and second arms 1.7 are both 4 degrees apart from the horizontal plane. The right-angle fork formed by the first arm 1.6 and the second arm 1.7 has a hollow interior and a cylindrical cross, and the intersection is in a penetrating shape. The shape, diameter and depth of the right-angle fork arm match the U-shaped plug 2 and the locking pin 3 respectively; the bottom of a single monomer of the supporting embedded part 1 is an "I" rectangular base 1.5, and its width is the same as that of the right-angle fork arm. On both sides, according to the thickness of the protective layer of the floor steel bars 9 of the cast-in-place concrete floor 8, the vertical and horizontal cross arrangement working conditions of the floor steel bars 9 and the diameter of the floor steel bars 9, there are respectively arranged The longitudinal steel bar grooves 1.2 supporting the longitudinal and transverse floor steel bars 9 are staggered up and down on both sides of the "I" rectangular base 1.5. When the lower longitudinal steel bar grooves 1.2 are arranged to support the floor steel bars 9, the thickness of the protective layer of the floor steel bars 9 can be met. A transverse steel bar groove 1.3 is arranged at the upper part of one end of the "I" rectangular base 1.5. The setting principle is the same as that of the longitudinal steel bar grooves 1.2. Binding rings 1.4 are arranged at appropriate positions of the longitudinal steel bar grooves 1.2 and the transverse steel bar grooves 1.3. When the longitudinal steel bar grooves When 1.2 and the transverse steel bar groove 1.3 respectively support the corresponding floor slab steel bars 9, the pluggable support embedded components can be tied together with the floor slab steel bars 9 by using the binding wire through the binding ring 1.4, and play the role of a steel bar protective layer pad; the bottom of the "I"-shaped rectangular base 1.5 is bow-shaped, and the contact surface with the template 10 is a grid-like protrusion. The "bow" shape and the grid-like protrusion setting can minimize the contact surface with the template 10 to avoid obvious support marks when removing the template 10 of the cast-in-place concrete floor 8, so as to improve the visual quality of the concrete.

[0031] The supporting embedded part 1 is a disposable product and can be made of non-steel materials, which can achieve the effect of energy and material saving.

[0032] U-shaped plug 2 is formed by bending and disassembling round steel wire, and is in U shape. The opening of the two legs of the U-shaped plug 2 is adapted to the distance between the two monomers of the support embedded part 1, and can meet the working condition requirements of the oblique adjustment support rod 5. The U-shaped plug 2 is bent 450 degrees at the same appropriate position of the two legs, and the bent part is preferably such that the two legs can be fully inserted into the first arm 1.6 of the support embedded part 1, and a pin hole 2.2 is opened at an appropriate position at one end of the two legs inserted into the first arm 1.6 of the support embedded part 1, and the diameter of the pin hole 2.2 is adapted to the thinner end of the locking pin 3, so as to be inserted into the locking pin 3; the other part of the bending of the two legs of the U-shaped plug 2 is welded with a pin ear 2.1 towards the horizontal adjustment support rod 6, and a round hole is opened in the pin ear 2.1, and the diameter of the round hole is adapted to the working pin shaft 6.1 of the connecting end of the horizontal adjustment support rod 6.

[0033] The locking pin 3 is in the shape of a round rod, with a ring at one end and the other thinner end being a round rod with a variable cross-section, and the end of the round rod with a variable cross-section is in the shape of a truncated cone; the ring end of the locking pin 3 is convenient for applying external force to pull the locking pin 3 out of the supporting embedded part 1, and the thinner end of the round rod with a variable cross-section is convenient for inserting into the pin hole 2.2 of the U-shaped plug 2 and passing through the pin hole 2.2. The length of the thinner end of the round rod with a variable cross-section should be able to prevent the U-shaped plug 2 from escaping from the supporting embedded part 1 by itself.

[0034] The sealing ring 4 is generally a band-shaped wedge-shaped ring with a convex ring at the larger end. The sealing ring 4 has a certain elasticity and can be tightly clamped on the U-shaped plug 2 and the locking pin 3 and seal the gap between the U-shaped plug 2 and the locking pin 3 and the supporting embedded part 1.

[0036] Innovation: The innovation of the present invention is: (1) The present invention designs a pluggable support pre-embedded component consisting of a support pre-embedded part 1, a sealing ring 4, a U-shaped plug 2 and a locking pin 3 according to the construction process of a tool-type formwork 10 made of aluminum alloy or the like, which can be used as a support fixing point for a horizontal adjustment support rod 6 and an oblique adjustment support rod 5 of a vertical tool-type formwork 7 on the cast-in-place concrete floor 8 when pre-embedded in the cast-in-place concrete floor 8; after the supporting work is completed, the sealing ring 4, the U-shaped plug 2 and the locking pin 3 in the pluggable support pre-embedded component can be removed and reused.

[0037] (2) The supporting embedded part 1 is composed of two single parts with the same structure connected into a whole by a connecting rod 1.1. The upper part of the single part of the supporting embedded part 1 is two right-angle fork arms crossing at 90 degrees. The first arm 1.6 and the second arm 1.7 of the right-angle fork arms cross at 45 degrees with the horizontal plane. The inside of the right-angle fork arms cross in a cylindrical shape. The right-angle fork arms are inserted into the U-shaped plug 2 and the locking pin 3. The single unit of the supporting embedded part 1 is designed with a longitudinal steel bar groove 1.2, a transverse steel bar groove 1.3, and a binding ring 1.4, which can well adapt to the distribution and fixation of the floor slab steel bars 9 and can play the role of a steel bar protective layer pad. The contact between the supporting embedded part 1 and the formwork 10 is designed in a grid-like protrusion, which can reduce the contact surface with the formwork 10 and improve the visual quality of the concrete.

[0038] (3) The two legs of the U-shaped plug 2 are bent at 45 degrees, and a pin hole 2.2 is opened at the separated ends of the two legs. A pin ear 2.1 is welded on the end where the legs are connected. The U-shaped plug 2 is inserted into the supporting embedded part 1. When the concrete is poured, its stress condition can be used as a supporting fixed point and can be reused.

[0039] (4) The locking pin 3 has a ring at one end and a round rod with a variable cross-section at the other thinner end. When the locking pin 3 is inserted into the pin hole 2.2 of the U-shaped pin 2 through the supporting embedded part 1, it can prevent the U-shaped pin 2 from escaping from the supporting embedded part by itself, thereby serving as a supporting fixed point.

[0040] The invention has a simple structure and convenient manufacturing materials, and can be made into shaped products according to needs; its construction method is simple in process, easy to assemble and disassemble, and has guaranteed construction quality; its main components can be recycled, and it meets the requirements of energy conservation and environmental protection.
