Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated buildings, and in particular relates to a modular steel structure prefabricated building. Background Art

[0002] Buildings assembled on site from prefabricated components are called prefabricated buildings. According to the form of prefabricated components and construction methods, they are divided into five types: block buildings, plate buildings, box buildings, frame plate buildings, and raised plate and raised floor buildings.

[0003] Chinese patent application No. 202322747522.5 discloses a modular building steel structure, including a base frame, both sides of the bottom end of the base frame are welded with an overhead mechanism, and both sides of the top end of the base frame are welded with support columns, the top ends of the support columns are welded with a crossbeam, and the inner wall of the crossbeam is welded with a reinforcing steel frame. Through the overhead mechanism, it is convenient to construct the frame of the modular building through the connecting block and the support block in the overhead mechanism at the bottom of the base frame to perform an overhead operation on the entire building frame, so that when the modular building is put into use, the floor in the building can be prevented from fitting to the ground, causing ground moisture to enter the interior of the building. At the same time, the steel structure frame of the building can be fixed to the ground through the fixing rod on the inner wall of the support block, which can provide a fixing effect on the building in windy weather, and the reinforcing steel frame welded on the inner wall of the crossbeam can reinforce the beams of the modular building, thereby improving the structural stability of the overall modular building.

[0004] In the above-mentioned patent, an overhead mechanism is used to fix the base frame to the place of use. When encountering windy and rainy weather, the base frame is easily moved due to force, affecting the stability of the entire device. When laying structures such as floors on the base frame, the floors at the hollow positions between the base frames have no support, causing the floors to be suspended, affecting the use effect of the floors. In addition, during the process of welding the base frame and the support columns, it is necessary to manually fix the support columns and then weld the support columns to the base frame, which affects the labor efficiency of the staff. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a modular steel structure assembled building, which has the characteristics of counterweight, stable support and plug-in positioning.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a modular steel structure prefabricated building, comprising a base frame, an overhead mechanism is arranged below the base frame, a support column is arranged above the base frame, a top frame is arranged at one end of the support column away from the base frame, counterweight assemblies are arranged at both ends below the base frame and between the two overhead mechanisms, a support assembly is arranged between the two counterweight assemblies, and positioning assemblies are arranged between the support column and the base frame and between the support column and the top frame.

[0007] Preferably, the counterweight assembly includes a placement box, a counterweight block and a limit piece, both lower ends of the base frame are connected to a placement box, a counterweight block is arranged inside the placement box, and a limit piece is arranged between the placement box and the counterweight block.

[0011] Preferably, both sides of one end of the support rod close to the fixing sleeve are connected to limiting sliders, and limiting sliding grooves are arranged on the inner side wall of the fixing sleeve at positions corresponding to the limiting sliders.

[0012] Preferably, the positioning assembly includes a positioning screw, a positioning slot, a positioning block and a positioning nut. Positioning slots are provided at both ends of the support column, and the bottom frame and the top frame are connected to one end of the positioning slot close to the positioning slot. A positioning screw is inserted between the support column and the positioning block, and one end of the positioning screw is connected to a positioning nut.

[0013] Preferably, a sealing cylinder is connected to the outer side wall of the positioning nut, a sealing groove is provided on the side wall of the support column at a position corresponding to the sealing cylinder, and a sealing ring is connected to one end of the sealing cylinder close to the sealing groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention sets a counterweight assembly. After the base frame is plugged into the use site by using the overhead mechanism, the limit rod is pulled downward. The limit rod moves to drive the external rod to move inside the moving groove. The external rod moves to squeeze the first spring. When the limit rod moves and is retracted into the moving groove, the counterweight block is placed inside the placement box. Then the limit rod is released. The first spring loses the external force and returns to its original appearance, driving the limit rod to move and protrude from the moving groove. The limit rod can be used to limit and fix the counterweight block to ensure the stability of the placement of the counterweight block. Under the action of the counterweight block, the stability of the base frame placement can be guaranteed, and then the stability of the placement of the entire device can be guaranteed.

[0016] 2. The present invention provides a support assembly. After the assembly of the top frame, the support column and the bottom frame is completed, the floor is laid on the bottom frame. During the laying process, the support plate is squeezed by the floor to drive the support rod to move into the fixed sleeve. The support rod moves to squeeze the second spring. The support plate can be used to support the floor to ensure the stability of the floor laying.

[0017] 3. The present invention provides a positioning assembly. When welding operations need to be performed on the support column, the base frame and the top frame, the positioning groove at the end of the support column is aligned with the positioning block on the base frame, and the support column is moved to fit the side wall of the base frame. The positioning screw is then inserted into the support column and the positioning block. The positioning nut is then rotated and screwed onto the outer wall of the positioning screw. The sealing cylinder is then inserted into the sealing groove. The positioning screw and the positioning nut can be used to position and fix the support column and the positioning block, and then the support column and the base frame can be positioned and fixed, thereby ensuring the stability of the placement of the support column and the base frame and avoiding movement of the support column during subsequent welding operations on the support column and the base frame, thereby affecting the welding effect.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1-6 The present invention provides the following technical solutions: A modular steel structure assembled building, including a base frame 3, an overhead mechanism 5 is arranged below the base frame 3, a support column 2 is arranged above the base frame 3, a top frame 1 is arranged at one end of the support column 2 away from the base frame 3, counterweight assemblies 4 are arranged at both ends below the base frame 3 and between the two overhead mechanisms 5, a support assembly 6 is arranged between the two counterweight assemblies 4, and positioning assemblies 7 are arranged between the support column 2 and the base frame 3 and between the support column 2 and the top frame 1.

[0028] Specifically, the counterweight assembly 4 includes a placement box 41, a counterweight block 42 and a limiter 44. The two ends below the bottom frame 3 are connected to the placement box 41, the counterweight block 42 is arranged inside the placement box 41, and the limiter 44 is arranged between the placement box 41 and the counterweight block 42.

[0029] By adopting the above technical solution, after the base frame 3 is plugged into the use place using the overhead mechanism 5, the counterweight block 42 is placed inside the placement box 41, and the counterweight block 42 is limited and fixed using the limiting member 44. Under the action of the counterweight block 42, the stability of the placement of the base frame 3 can be guaranteed, and then the stability of the placement of the entire device can be guaranteed.

[0030] Specifically, the limiting member 44 includes a limiting rod 441, an external rod 442, a moving groove 443 and a first spring 444. The placing box 41 is provided with a moving groove 443 inside, the limiting rod 441 is inserted inside the moving groove 443, the two side walls of the limiting rod 441 are connected to the external rod 442, and the first spring 444 is connected between the external rod 442 and the moving groove 443.

[0031] By adopting the above technical solution, the limit rod 441 is pulled downward, and the limit rod 441 moves to drive the external rod 442 to move inside the moving groove 443. The external rod 442 moves to squeeze the first spring 444. When the limit rod 441 moves and is retracted into the moving groove 443, the counterweight block 42 is placed inside the placement box 41, and then the limit rod 441 is released. The first spring 444 loses the external force and returns to its original state, driving the limit rod 441 to move and protrude out of the moving groove 443. The limit rod 441 can be used to limit and fix the counterweight block 42 to ensure the stability of the placement of the counterweight block 42.

[0032] Specifically, a plurality of drain holes 43 are provided on the side wall of the placement box 41 and below the counterweight block 42.

[0033] By adopting the above technical solution, when encountering rainy weather, rainwater entering the placement box 41 is discharged into the surrounding environment through the drainage hole 43, thereby preventing rainwater from gathering inside the placement box 41.

[0034] When the present embodiment is used, when the steel structure frame of the modular building is constructed, the base frame 3 is plugged into the use site by using the overhead mechanism 5, and the limit rod 441 is pulled downward, and the limit rod 441 moves to drive the external rod 442 to move inside the moving groove 443, and the external rod 442 moves to squeeze the first spring 444. When the limit rod 441 moves and is collected into the moving groove 443, the counterweight block 42 is placed in the placement box 41, and then the limit rod 441 is released, and the first spring 444 loses its locking position. The external force restores the original appearance and drives the limit rod 441 to move and protrude the moving groove 443. The limit rod 441 can be used to limit and fix the counterweight block 42 to ensure the stability of the placement of the counterweight block 42. Under the action of the counterweight block 42, the stability of the placement of the base frame 3 can be ensured, and then the stability of the placement of the entire device can be ensured. Then, the support column 2 is welded to the upper four corners of the base frame 3, and then the top frame 1 is welded to the top of the support column 2, and the assembly operation of the top frame 1, the support column 2 and the base frame 3 is completed;

[0035] Example 2

[0036] The present embodiment is different from the embodiment 1 in that: the support assembly 6 includes a support plate 61, a support rod 62, a fixing sleeve 63, a second spring 64 and a cross plate 65, a cross plate 65 is connected between the two placement boxes 41, a plurality of fixing sleeves 63 are connected above the cross plate 65, a support rod 62 is inserted inside the fixing sleeve 63, a second spring 64 is connected between the support rod 62 and the fixing sleeve 63, and a support plate 61 is connected to one end of the support rod 62 away from the fixing sleeve 63.

[0037] Specifically, both sides of the end of the support rod 62 close to the fixed sleeve 63 are connected to the limit sliders, and the inner wall of the fixed sleeve 63 is provided with a limit slide groove at the position corresponding to the limit slider.

[0038] By adopting the above technical solution, the movement of the support rod 62 drives the limit slider to move inside the limit slide groove. When the limit slider moves to fit the side wall of the limit slide groove, the limit slider is blocked and stops moving, thereby preventing the support rod 62 from continuing to move and preventing the support rod 62 from detaching from the fixing sleeve 63.

[0039] When the present embodiment is used, after the top frame 1, the support column 2 and the bottom frame 3 are assembled, the floor is laid on the bottom frame 3. During the laying process, the support plate 61 is squeezed by the floor to drive the support rod 62 to move inside the fixing sleeve 63. The support rod 62 moves to squeeze the second spring 64. The support plate 61 can be used to support the floor to ensure the stability of the floor laying.

[0040] Example 3

[0041] The present embodiment is different from the first embodiment and the second embodiment in that the positioning assembly 7 includes a positioning screw 71, a positioning groove 72, a positioning block 73 and a positioning nut 75. The two ends of the support column 2 are provided with positioning grooves 72. The ends of the bottom frame 3 and the top frame 1 close to the positioning grooves 72 are connected with positioning blocks 73. The positioning screw 71 is inserted between the support column 2 and the positioning block 73. One end of the positioning screw 71 is connected with a positioning nut 75.

[0042] Specifically, a sealing cylinder 74 is connected to the outer wall of the positioning nut 75, a sealing groove is provided on the side wall of the support column 2 at a position corresponding to the sealing cylinder 74, and a sealing ring is connected to one end of the sealing cylinder 74 close to the sealing groove.

[0043] By adopting the above technical solution, after the positioning nut 75 is rotated and screwed onto the outer wall of the positioning screw 71, the sealing cylinder 74 is inserted into the sealing groove. Under the action of the sealing ring, a gap between the sealing cylinder 74 and the sealing groove can be avoided, thereby ensuring the sealing effect of the sealing cylinder 74. Under the action of the sealing cylinder 74, rainwater can be prevented from falling onto the positioning screw 71 and the positioning nut 75, causing the positioning screw 71 and the positioning nut 75 to rust, thereby affecting the stability of the connection between the positioning screw 71 and the positioning nut 75.

[0044] When the present embodiment is in use, when it is necessary to perform welding operations on the support column 2, the base frame 3 and the top frame 1, the positioning groove 72 at the end of the support column 2 is aligned with the positioning block 73 on the base frame 3, and then the support column 2 is moved to fit the side wall of the base frame 3, and then the positioning screw 71 is inserted into the support column 2 and the positioning block 73, and then the positioning nut 75 is rotated and screwed onto the outer wall of the positioning screw 71, and the sealing cylinder 74 is inserted into the sealing groove. The positioning screw 71 and the positioning nut 75 can be used to position and fix the support column 2 and the positioning block 73, and then the support column 2 and the base frame 3 can be positioned and fixed, so as to ensure the stability of the placement of the support column 2 and the base frame 3, and avoid the support column 2 from moving during the subsequent welding operation on the support column 2 and the base frame 3, which affects the welding effect, and then the same method is used to weld the top frame 1 and the support column 2.

[0045] The working principle and use process of the present invention are as follows: when constructing the steel structure frame of the modular building, the present invention uses the overhead mechanism 5 to insert the base frame 3 into the use place, and then pulls the limit rod 441 downward. The limit rod 441 moves to drive the external rod 442 to move inside the moving groove 443. The external rod 442 moves to squeeze the first spring 444. When the limit rod 441 moves and is collected into the moving groove 443, the counterweight block 42 is placed inside the placement box 41, and then the limit rod 441 is released. The first spring 444 loses the external force and restores its original appearance to drive the limit rod 441 to move and protrude from the moving groove 443. The limit rod 441 can be used to limit and fix the counterweight block 42 to ensure the stability of the placement of the counterweight block 42. Under the action of the counterweight block 42, the stability of the placement of the base frame 3 can be ensured, and then the stability of the placement of the entire device can be ensured. The positioning groove 72 at the end of the support column 2 is aligned with the positioning block 73 on the base frame 3, and then the support column 2 is moved to fit the side wall of the base frame 3. When the locking nut 75 is engaged, the locking nut 77 is engaged with the locking nut 71 and the fixing nut 78 is engaged with the fixing nut 76 to fix the locking nut 76 on the fixing nut 78.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
