The purpose of formwork engineering is to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce costs.

[0003] At present, most of the existing technologies still use steel pipes and fasteners to build floor slab supports. During the construction process, multiple steel pipes and fasteners are needed to build multiple floor slab support frames.

DETAILED DESCRIPTION

[0041] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides an assembled building support structure, which drives the adjustment component 403 to make two groups of bearing members 100 move back and forth or towards each other at the same time, thereby adjusting the horizontal height of the support plate 202d in the support component 202, and by adjusting the cooperation between the separation connection component 402 and the driving adjustment component 403, when the driving adjustment component 403 is driven, one group of bearing members 100 is fixed and the other group of bearing members 100 moves, thereby adjusting the inclination angle of the support plate 202d in the support assembly 202; the height and angle can be adjusted according to the construction environment, and the disassembly type construction can be realized, which is convenient for transportation and assembly, saving time and labor and improving work efficiency.

[0042] Specifically, in the initial state, refer to Figure 2 and Figure 3 The upper support unit 200, the lower support unit 300 and the fixing assembly 500 are in a folded state. First, one end of the two sets of supporting members 100 is vertically inserted into the movable support 302. The number of movable supports 302 is the same as the number of supporting members 100. In this embodiment, two sets are used as an example. A first sliding groove is provided on the base 301, and the movable support 302 can slide in the first sliding groove, and then the other end of the carrier 100 is inserted into the socket 202a of the support assembly 202. The number of sockets 202a is the same as the number of carriers 100, and the snap assembly 401 and the separation connection assembly 402 are respectively installed on the two groups of carriers 100. In order to adjust the distance between the two groups of carriers 100, an adjustment assembly 403 is transmitted between the snap assembly 401 and the separation connection assembly 402; the distance between the two groups of carriers 100 is changed by the adjustment assembly 403, thereby adjusting the height of the support plate 202d, and then by adjusting the separation connection assembly 402, when the adjustment assembly 403 is driven, one group of carriers 100 is fixed and the other group of carriers 100 moves, thereby adjusting the inclination angle of the support plate 202d. In order to keep the adjustment component 403 fixed, a fixing component 500 is slidably provided on the base 301 . The fixing component 500 limits the lateral movement of the adjustment component 403 but does not limit the axial rotation of the adjustment component 403 .

[0043] It should be noted that the bearing member 100 is preferably a cylindrical steel pipe, and the movable support 302 and the sleeve 202a can be designed according to the shape of the bearing member 100 to achieve an adaptation effect.

[0044] Preferably, mutually compatible fasteners can be provided on both sides of the upper support unit 200 and the lower support unit 300 to connect them into one, which is convenient for subsequent transportation and assembly.

[0045] Furthermore, connecting arms 201 a are provided at both ends of the connecting plate 201 ; one end of the connecting arm 201 a is hinged to the connecting plate 201 and the other end is hinged to the supporting assembly 202 .

[0046] Furthermore, the connecting plate 201 is provided with a slide rail; the supporting assembly 202 includes: a socket 202a provided at the bottom of the connecting plate 201 and pluggably connected to the carrier 100, a positioning assembly 202b provided above the socket 202a, support arms 202c hingedly provided on both sides of the positioning assembly 202b, and a support plate 202d hingedly provided at one end of the support arm 202c away from the positioning assembly 202b;

[0047] A first sliding block is provided between the positioning assembly 202b and the sleeve 202a, and the first sliding block is slidably engaged with the slide rail.

[0048] It should be noted that, in combination with the context and Figures 1-3 As can be seen, the support arm 202c is hinged to the connecting arm 201a. This design aims to form a triangular support structure between the support arm 202c, the connecting arm 201a, and the connecting plate 201, thereby sharing the transferred load and providing greater stability. However, adjusting the distance between the supporting members 100 adjusts the angle and height of the support plate 202d.

[0049] Furthermore, the buckle assembly 401 includes: a first buckle 401a detachably mounted on one of the carriers 100 , and a first mounting block 401b mounted on the first buckle 401a ; a threaded hole is disposed in the first mounting block 401b .

[0050] Furthermore, the separation connection assembly 402 includes: a second buckle 402a detachably mounted on another set of the carriers 100, a second mounting block 402b mounted on the second buckle 402a, a movable sleeve 402c slidably mounted on the second mounting block 402b, and a threaded sleeve 402d slidably mounted within the movable sleeve 402c.

[0051] The inner wall of the movable sleeve 402c is provided with a first slide 402c-1, and a second slide 402c-2 is provided on one side of the first slide 402c-1; there is at least one group of blocks 402c-3 in the first slide 402c-1, and the outer wall of the threaded sleeve 402d is provided with at least one group of driving blocks 402d-1; a notch channel 402c-4 is provided on the side of the first slide 402c-1 close to the second slide 402c-2; when the movable sleeve 402c is moved under the action of external force, the driving block 402d-1 can switch between the first slide 402c-1 and the second slide 402c-2.

[0052] Furthermore, the adjustment assembly 403 includes: a forward and reverse threaded rod with both ends threadedly connected to the threaded sleeve 402d and the first mounting block 401b, and a fixed bearing seat arranged in the middle of the forward and reverse threaded rod.

[0053] It should be noted that the first buckle 401a and the second buckle 402a are steel pipe buckles, which can be fixed to the bearing component 100 by bolts.

[0054] It should be noted that a shaking handwheel is provided at the end of the forward and reverse threaded rod to facilitate rotation by the operator. The forward and reverse threaded rod has a forward threaded portion and a reverse threaded portion. The forward threaded portion is adapted to the threaded hole in the first mounting block 401b, and the reverse threaded portion is adapted to the threaded sleeve 402d. Therefore, by rotating the forward and reverse threaded rod, the two groups of carriers 100 can be brought closer or farther away.

[0055] Preferably, in combination with the context and the figure, the fixed bearing seat in the middle of the forward and reverse screw rods is cooperated with the fixed component, and the connection between the fixed component and the fixed bearing limits the lateral movement of the forward and reverse screw rods, but does not limit the axial rotation of the forward and reverse screw rods.

[0056] Preferably, a second slide groove is provided on the second mounting block 402b, and a third slider is provided on the movable sleeve 402c, and the second slide groove cooperates with the third slider. Alternatively, a through opening can be provided on the second mounting block 402b, and a latch is provided in the through opening. The latch extends to be located in the second slide groove. When the movable sleeve 402c moves, the latch is inserted, thereby limiting the movement of the movable sleeve 402c. If the movable sleeve 402c needs to be moved again, the latch is pulled out and inserted again after the movement to achieve the limiting of the movable sleeve 402c.

[0057] Preferably, the first slideway 402c-1 and the second slideway 402c-2 are opened along the circumferential direction of the inner wall of the movable sleeve 402c to form an annular structure.

[0058] Preferably, when the construction environment requires planar support of the support plate 202d, that is, when adjusting the height of the support plate 202d, the movable sleeve 402c limits the threaded sleeve 402d, and the fixed component 500 limits the positive and negative screws to ensure that the positive and negative screws can drive their relative support members 100 to move when rotating. At this time, the driving block 402d-1 on the outer wall of the threaded sleeve 402d and the stop block 402c-3 of the first slide 402c-1 on the inner wall of the movable sleeve 402c are offset, limiting the self-rotation of the threaded sleeve 402d, thereby enabling the two groups of support members 100 to approach or move away. When moving away, the support plate 202d is raised in height under the action of the support arm 202c and the connecting arm 201a, and on the contrary, it is lowered in height when approaching.

[0059] Preferably, when the construction environment requires the support plate 202d to be supported on an inclined surface, such as when supporting stair formwork or ramp formwork, the inclination angle or height of the support plate 202d needs to be adjusted. Therefore, the distance between the supporting members 100 is first adjusted to achieve height correspondence according to the construction situation, and then the inclination angle is adjusted. Specifically, the user moves the movable sleeve 402c, and at this time, the driving block 402d-1 on the threaded sleeve 402d enters the second slide 402c-2 through the notch channel 402c-4. Because the second slide 402c-2 is not provided with a block, when the positive and negative threaded rods are driven to rotate, the threaded sleeve 402d will rotate in the second slide 402c-2, so that the relative supporting member 100 will not move. Then, the first mounting block 401b on the other set of supporting members 100 is engaged with the positive and negative threaded rods, realizing the movement of only one supporting member 100. Therefore, when only one of the two groups of bearing members 100 moves and the other is fixed, the support plate 202d will inevitably be tilted, and the tilt angle of the construction environment can be met by fine-tuning the distance between the bearing members 100.

[0060] Furthermore, a first sliding groove 301a is provided on the base 301;

[0061] The fixing assembly 500 includes: a lifting block 501 arranged in the first sliding groove 301a, a second slider 502 arranged on both sides of the lifting block 501 and cooperating with the first sliding groove 301a, two sets of connecting rods 503 respectively hinged at both ends between the lifting block 501 and the second slider 502, a steel bar 504 rotatably arranged on the top of the lifting block 501, and a buckle 505 arranged on the top of the steel bar 504; the buckle 505 cooperates with the adjusting assembly 403; and connecting holes are set at both ends of the steel bar 504.

[0062] It should be noted that, in the initial state, the fixing assembly 500 is in a folded state, the lifting block 501 is located in the first slide groove 301a, the relative connecting rods 503 and 504 are both located in the first slide groove 301a, and the steel bar 504 is located horizontally in the first slide groove 301a, which is convenient for transportation in the folded state and saves transportation space; the buckle 505 fixes the position of the adjustment assembly 403 to maintain stability.

[0063] Preferably, the context and the Figures 1 and 2 It can be seen that the buckle 505 in the present invention is connected to the fixed bearing seat in the middle of the forward and reverse screw rods. When in use, the operator lifts the lifting block 501 from the first slide groove 301a. At this time, the two sets of connecting rods 503 will be in a vertical state. In order to maintain the stability of the forward and reverse screw rods, the buckle 505 is fixedly connected to the fixed bearing seat in the middle of the forward and reverse screw rods to limit the lateral movement of the forward and reverse screw rods and ensure that they can rotate axially.

[0064] Preferably, the steel bar 504 rotatably connected to the lifting block 501 is rotated at a certain angle, and the connection hole at its end is bolted to the connection hole of another prefabricated building support structure, thereby ensuring the overall connectivity and stability.

[0065] Furthermore, the positioning assembly 202b includes: a positioning seat 202b-1 connected to the first slider, positioning slots 202b-2 provided at both ends of the positioning seat 202b-1, a swinging rod 202b-3 rotatably disposed in the positioning slots 202b-2, and a mounting piece 202b-4 provided on one side of the positioning seat 202b-1 and used to fix the end of the swinging rod 202b-3; a threaded hole is provided at the upper end of the swinging rod 202b-3, and a sliding opening is provided on the mounting piece 202b-4, and the threaded hole and the sliding opening are connected by screws, thereby limiting the position of the swinging rod 202b-3;

[0066] The connecting plate 201 is provided with positioning grooves on both sides of the slide rail, and a plurality of positioning slots 201b are provided in the positioning grooves; the positioning slots 201b are adapted to the ends of the swing rods 202b-3.

[0067] It should be noted that, in order to achieve the stability of the support plate 202d, the swing rod 202b-3 and the positioning slot 201b are engaged with each other to achieve the limitation of the positioning seat 202b-1, thereby achieving the limitation of the support plate 202d.

[0068] Preferably, before rotating the forward and reverse screws, tighten the screws to lock the swing arm 202b-3 and the mounting plate 202b-4, so that the end of the swing arm 202b-3 is disengaged from the positioning slot 201b. At this time, after rotating the forward and reverse screws to adjust the relative height and inclination of the support plate 202d, loosen the screws to drive the swing arm 202b-3 to counteract the positioning slot 201b, thereby achieving limiting and sharing part of the load on the connecting plate 201, thereby achieving further stability of the device.

[0069] Preferably, the screw can move in the sliding opening of the mounting plate 202b-4, thereby achieving connection to the swing rod 202b-3. Example

[0070] Reference Figures 7 and 8 This is the second embodiment of the present invention. It differs from the first embodiment in that, as can be seen above, the screws must be loosened to achieve contact between the swing arm 202b-3 and the positioning slot 201b. Therefore, the load on the support plate 202d is inevitably transferred to the screws. Furthermore, because the screws are threadedly connected to the swing arm 202b-3, this is not suitable for construction environments subject to high loads. In addition to the screw locking mechanism, a structure is designed to limit the swing of the swing arm 202b-3, making the equipment more stable.

[0071] Specifically, the positioning assembly 202b further includes: a locking box 202b-5 disposed between the two sets of swing rods 202b-3, and limiting blocks 202b-8 disposed on both sides of the locking box 202b-5; the locking box 202b-5 has first locking holes formed on both side walls in the width direction, second locking holes formed on both side walls in the length direction, and a third locking hole formed on the top wall; the limiting block 202b-8 has a limiting hole coaxial with the first locking hole;

[0072] The positioning assembly 202b further includes: a moving member 202b-6 that is transmission-disposed in the locking box 202b-5 and whose end passes through the third locking hole, and limiting rods 202b-7 that pass through the first locking hole and the limiting hole and are located on both sides of the moving member 202b-6; the moving member 202b-6 is provided with a through opening coaxial with the second locking hole, and locking rods 202b-9 are provided in the second locking hole and the through opening; the limiting rod 202b-7 is configured to be arc-shaped at one end adjacent to the moving member 202b-6, and the contact surface between the moving member 202b-6 and the limiting rod 202b-7 is configured to be arc-shaped;

[0073] A spring is provided between the bottom of the moving member 202b-6 and the bottom side wall of the locking box 202b-5; a spring is provided between the two groups of limiting rods 202b-7 and the locking box 202b-5 respectively.

[0074] It should be noted that the purpose of this embodiment is to further fix the swing arm 202b-3. As described above, when the screws are loosened so that the swing arm 202b-3 is engaged with the positioning slot 201b, by pressing the movable part 202b-6 in this embodiment, the limiting rod 202b-7 is extended out of the locking box 202b-5 along the first locking hole and corresponds to the limiting hole on the limiting block 202b-8. At this time, the locking rod is inserted into the movable part 202b-6 along the second locking hole of the locking box 202b-5 and passes through the locking box 202b-5. At this time, the limiting rod 202b-7 is close to one side of the swing arm 202b-3, limiting its swinging and ensuring the stability of the device.

[0075] Preferably, a first spring is connected to the bottom of the movable member 202b-6 and the bottom inner wall of the locking box 202b-5, and a second spring is also arranged between the two sets of limiting rods 202b-7 and the side wall of the locking box 202b-5. Preferably, the elastic force of the first spring is greater than the elastic force of the second spring; therefore, when the device in the present invention needs to be disassembled, the locking rod 202b-9 is first pulled out, and at this time the movable member 202b-6 pops out first under the reset of the first spring, and then the two sets of limiting rods 202b-7 disengage from the limiting hole, thereby releasing the limit on the swing rod 202b-3.

[0076] Preferably, in the initial state of the present invention, the connecting arm 201a and the supporting arm 202c of the upper support unit 200 are tilted and in a folded state, and the fixing assembly 500 of the lower support unit 300 is also in a folded state, and the steel bar 504 is folded horizontally in the first chute 301a for easy transportation. When in use, the upper support unit 200 and the lower support unit 300 are disassembled. According to the supporting method of the prefabricated building support structure in the above case, the following steps are specifically included:

[0077] Step 1: First, insert the two ends of the two sets of bearing members 100 into the sleeves of the upper support unit 200 and the movable support 302 of the lower support unit 300 respectively;

[0078] Step 2: Thread the two ends of the forward and reverse screw rods into the buckle assembly 401 and the separation connection assembly 402 respectively; install the forward and reverse screw rods horizontally between the two sets of support members 100, and install the buckle assembly 401 and the separation connection assembly 402 on the two sets of support members 100 respectively;

[0079] Step 3: Lift the lifting block 501 from the first slide slot 301a, vertically position the connecting rod 503 and the base 301, rotate the steel bar 504, connect the buckle 505 on the top of the lifting block 501 to the fixed bearing seat in the middle of the positive and negative threaded rods, and connect the connecting holes at both ends of the steel bar 504 to other prefabricated building support structures on both sides;

[0080] Step 4: Tighten the screws to lock the swing rod 202b-3 and the mounting plate 202b-4, so that the swing rod 202b-3 is disengaged from the positioning slot 201b; rotate the positive and negative threaded screws to make the two groups of bearing members 100 move away from or towards each other, thereby adjusting the height of the support plate 202d; if you want to tilt the support plate 202d, move the movable sleeve 402c in the separation connection assembly 402, and then rotate the positive and negative threaded screws again. The threaded sleeve rotates in the movable sleeve, so that one of the bearing members 100 does not move, and the other bearing member 100 moves closer to or farther away from the fixed bearing member 100, thereby tilting the support plate 202d;

[0081] Step 5. Loosen the screws to drive the swing arm 202b-3 to collide with the positioning slot 201b, press the moving part 202b-6 to clamp the limiting rod 202b-7 into the limiting hole of the limiting block 202b-8 to limit the rotation of the swing arm 202b-3, and finally insert the locking rod 202b-9 into the second locking hole of the locking box 202b-5 and the opening of the moving part 202b-6 to further limit the swing arm 202b-3.
