The working principle of the green sustainable assembly type building system provided by the embodiment is as follows: can be with back timber 4 before the building assembly, floor 5, each structure installation in casing 6 and the 6 inner chambers of casing finishes, the job site is at first with support column 2 fixed mounting on the basis subaerial, install wallboard 3 to between two adjacent support columns 2 after, through hoisting machine structure and cooperation manual assistance with the back timber 4 after connecting again, floor 5 places in the top of the support column 2 that corresponds, make the top of the support column 2 that each casing 6 is aimed at to correspond, if there is the deviation in the distance between two support columns 2 this moment, accessible horizontal slip spliced pole 18, make between two grip blocks 14 that correspond in the casing 18 inserts, can realize the fixed connection of back timber 4 and support column 2 through rotating screw rod 19 at last. Among the prior art, owing to use the bolt to be connected roof mechanism (being equivalent to back timber 4 and floor 5's connector) and T type support column (being equivalent to support column 2), the bolt hole is fixed position, and the distance between two T type support columns needs very accurate control at specific length, otherwise this distance is long partially or short partially all can lead to the bolt can' T insert the bolt downthehole, can only be through fluting again, trompil, undoubtedly can greatly increased the construction degree of difficulty, and it is long when the increase construction. The main innovation point of the invention is that the connecting column 18 capable of horizontally sliding (the sliding direction is along the length direction of the top beam 4) is arranged, so that even if the distance between two adjacent supporting columns 2 for connecting the same top beam 4 is deviated, the distance between the two connecting columns 18 can be adjusted by sliding the connecting column 18, and the fixed connection between the top beam 4 and the supporting columns 2 can be realized by only rotating the screw rod 19 through the matching of the connecting column 18, the clamping plate 14 and the screw rod 19.

Compared with the prior art, the horizontal sliding of the connecting column 18 can realize the clamping of the connecting column 18 by the two clamping plates 14 when the distance between the two supporting columns 2 does not meet the requirement of accurate control and causes deviation from the set length, thereby realizing the firm connection between the supporting columns 2 and the top beam 4, greatly reducing the construction difficulty and improving the construction speed;

moreover, in this embodiment, when the support column 2 and the top beam 4 (or the connecting body of the top beam 4 and the floor 5) are firmly connected, only one action of rotating the screw rod 19 is needed, and compared with the bolt connection in the prior art, when fixing, the bolt connection can be realized only by rotating the bolt rod and fixing the bolt cap, which is very inconvenient in operation.

In this embodiment, the screw rod 19 is connected with the two clamping plates 14 through the extrusion plate 12, the extrusion plate 12 is vertically slidably disposed in the inner cavity of the housing 6, that is, each outer side surface of the extrusion plate 12 is slidably attached to each inner wall of the housing 6, so that the extrusion plate 12 can only move up and down, the top of the extrusion plate 12 is abutted to the bottom of the screw rod 19, the extrusion plate 12 is provided with a through hole 1202 for inserting the two clamping plates 14, and the inner wall of the through hole 1202 is slidably attached to the side surfaces (including the outer side surface, the front side surface and the back side surface) of the two clamping plates 14. Through the structure, when rotating screw rod 19, screw rod 19 will be vertical downstream, screw rod 19 constantly promotes stripper plate 12 downwards this moment, stripper plate 12 that moves down makes two grip blocks 14 slide in opposite directions to it is fixed with spliced pole 18 centre gripping to make two grip blocks 14, after the centre gripping is fixed, screw rod 19 stall, screw rod 19 and casing 6 relatively fixed, make stripper plate 12 unable removal, and then make two grip blocks 14 unable removal, realize the stable centre gripping to spliced pole 18.

The screwing column 21 is located between the two screws 19, so that when the screwing column 21 is rotated, the driving gear column 2101 is not easily separated from the two driven gears 20;

further, the top of the thick plate 601 is provided with a first accommodating groove 60101 corresponding to the two driven gears 20 one to one, the diameter of the first accommodating groove 60101 is not smaller than that of the driven gears 20, the top of the thick plate 601 is further provided with a second accommodating groove 60103 corresponding to the driving gear post 2101, and the depth of the second accommodating groove 60103 is not smaller than that of the first accommodating groove 60101. Based on the above structure, when the screwing column 21 is rotated to the limit state (at this time, the two clamping plates 14 clamp and fix the connection column 18), the driven gear 20 completely enters the first accommodating groove 60101, so that the top surface height of the driven gear 20 is not higher than that of the thick plate 601 (as shown in fig. 1, 2, and 3), and thus, in the using process, the driven gear 20 does not contact with an external object, and the external object is prevented from touching the driven gear 20 to cause the driven gear 20 to reversely rotate, so that the two clamping plates 14 and the connection column 18 are loosened;

still further, the screw post 21 is placed on the top of the thick plate 601, and when the screw post 21 is rotated to the limit state, the screw post 21 can be pulled upwards, so that the screw post 21 is withdrawn from between the two driven gears 20 (as shown in fig. 1, 2 and 3), and thus the screw post 21 does not interfere with the rotation of the two driven gears 20;

furthermore, the top of the extrusion plate 12 is provided with insertion grooves 1201 which correspond to the two screws 19 one to one, the screws 19 are rotatably inserted into the insertion grooves 1201, and the insertion grooves 1201 can limit the bottom of the screws 19, so that the screws 19 do not incline and shake when rotating, and the stability of the screws 19 when rotating is improved; the bottom of the insertion groove 1201 is provided with a plurality of balls 22 in a rolling manner, the bottom surface of the screw rod 19 abuts against the tops of the balls 22, and when the screw rod 19 is rotated, the balls 22 can be driven to roll, so that the rotating friction force of the screw rod 19 is reduced, and the smoothness of the screw rod 19 during rotation is improved.

In this embodiment, the connection column 18 includes a hemisphere 1801 and a cylinder 1802 sequentially arranged from top to bottom, the hemisphere 1801 and the cylinder 1802 are integrally connected, and the diameter of the hemisphere 1801 is greater than the diameter of the cross-section circle of the cylinder 1802. The hemisphere 1801 is located above the support column 2, the cylinder 1802 is located in the support column 2 and can penetrate out of the support column 2, and the two clamping plates 14 are located on the left side and the right side of the hemisphere 1801 respectively;

the clamping plate 14 comprises a body 1401, the side surfaces of the two bodies 1401, which are far away from each other, are arc-shaped and protrude outwards, the distance between the side surfaces of the two bodies 1401, which are far away from each other, is sequentially increased from top to bottom by using the design of the body 1401, the left inner wall and the right inner wall of the through hole 1202 are respectively in sliding fit with the side surfaces of the two bodies 1401, and the two bodies 1401 slide in opposite directions along with the continuous downward movement of the extrusion plate 12;

in this embodiment, first abutting grooves 1404 are symmetrically provided on opposite surfaces of the two bodies 1401, and the top ends of the two free ends 1405 of the first abutting grooves 1404 abut against the outer surface of the hemisphere 1801. Specifically, when the two clamping plates 14 clamp the connecting column 18, the top ends of the two free ends 1405 on the two bodies 1401 are abutted to the outer surface of the hemisphere 1801, and by utilizing the shape characteristics of the hemisphere 1801, when the two clamping plates 14 approach each other, the hemisphere 1801 can move upwards, so that the connecting column 18 moves upwards;
