Description

Technical Field

[0001] This invention relates to the field of tower crane standard section construction technology, and in particular to a tower crane standard section and a waterproof structure for the basement roof. Background Technology

[0002] Tower cranes, also known as tower hoists, are rotating cranes with their booms mounted on the upper part of a tall tower. They offer a large working space and are mainly used for the vertical and horizontal transport of materials and the installation of building components in building construction. They consist of three parts: a metal structure, a working mechanism, and an electrical system. The metal structure includes the tower body, boom, and base. The working mechanism has four parts: hoisting, luffing, slewing, and traveling. When a standard tower crane section collides with the basement roof, a pre-drilled opening is made. This opening needs to be waterproofed after the tower crane is installed. Current technology generally involves using an open opening with edge protection, or casting the floor slab and standard section together as a whole, or performing simple waterproofing. The operation process is complex and cumbersome, requires a long construction period, and is also inconvenient for subsequent dismantling. Some methods are also not conducive to waterproofing.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a waterproof structure for a tower crane standard section and a basement roof. The waterproof structure for a tower crane standard section and a basement roof includes a tower crane assembly 100 and a sealing assembly 200. The sealing assembly 200 is used to seal the opening in the roof when installing the tower crane assembly 100, which improves the efficiency of disassembly and assembly, thereby improving the construction efficiency of construction personnel.

[0029] Specifically, the tower crane assembly 100 includes a raft slab 101, a tower crane foundation 102, shear reinforcement 103, a standard section body 104, and a floor slab 105. The tower crane foundation 102 is located within the raft slab 101. The shear reinforcement 103 is fixed within the tower crane foundation 102, and one end of the shear reinforcement 103 extends into the post-cast raft slab 101. The standard section body 104 is fixed to the top of the tower crane foundation 102. The floor slab 105 is located above the tower crane foundation 102. An opening S is provided in the middle of the floor slab 105, and the standard section body 104 is located within the opening S.

[0030] For the post-construction of the raft foundation 101, the tower crane foundation 102 is first poured in the bearing layer of the basement pit, and then the raft foundation 101 is poured on the outside of the tower crane foundation 102. Multiple shear bars 103 are evenly distributed in the construction joint to strengthen the integrity of the tower crane foundation 102 and the raft foundation 101 and increase the anti-buoyancy capacity of the tower crane foundation 102. The bottom end of the standard section body 104 is fixed to the top of the tower crane foundation 102. This is existing technology and will not be described in detail here. The opening S is rectangular. After the concrete age of the tower crane foundation 102 reaches the tower crane installation requirements, the tower crane standard section and other components are installed to an independent height. When pouring concrete for the basement top slab, the opening S is reserved according to the position of the standard section.

[0031] The sealing assembly 200 is disposed on the outside of the opening S and includes a base plate 201, a connector 202, a positioning member 203, a sealing member 204, and a fastener 205. The base plate 201 is fixed to the top of the floor slab 105 and is located on both sides of the opening S. The connector 202 is disposed on the top of the base plate 201. The positioning member 203 is located on both sides of the connector 202. The sealing member 204 is disposed between the two base plates 201. The fastener 205 is disposed on both sides of the sealing member 204 and cooperates with the connector 202.

[0032] The base plate 201 has a rectangular structure and is fixed to the floor slab 105 with bolts. The construction personnel measure the position of the opening S to make the two base plates 201 symmetrically distributed, which facilitates the subsequent installation of the sealing element 204. The cooperation between the connector 202 and the positioning element 203 can fasten and limit the sealing element 204, so that the sealing element 204 can seal the opening S and prevent water from seeping down from the opening S. The fastener 205 is used to seal the contact position between the standard section body 104 and the sealing element 204. Without hindering its installation, it can greatly improve the sealing effect of the two, thereby improving the water-proof effect of the floor slab 105.

[0033] Example 2

[0034] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] The specific connector 202 includes a threaded tube 202a, a limiting frame 202b, and a stabilizing plate 202c. The threaded tube 202a is rotatably connected to the top of the substrate 201. The limiting frame 202b is fixed to the surface of the threaded tube 202a. The stabilizing plate 202c is fixed to both sides of the top of the substrate 201. The end of the stabilizing plate 202c away from the substrate 201 slides within the limiting frame 202b.

[0036] The threaded tube 202a is rotatably connected to the base plate 201 via a bearing. The threaded tube 202a is located at the center of the base plate 201. The limiting frame 202b is annular, and an annular groove is provided on the outer side of the limiting frame 202b. The stabilizing plate 202c is L-shaped. The bottom end of the stabilizing plate 202c is fixed to the base plate 201, and the top of the stabilizing plate 202c slides in the annular groove on the limiting frame 202b. The stabilizing plate 202c and the limiting frame 202b are used to limit the threaded tube 202a, improve the stability of the threaded tube 202a, and prevent the threaded tube 202a from moving up and down due to force during use.

[0037] The positioning component 203 includes a gear 203a, a toothed plate 203b, and a clamping plate 203c. The gear 203a is fixed to the bottom of the surface of the threaded tube 202a, the toothed plate 203b slides on the top of the base plate 201, the side of the toothed plate 203b meshes with the gear 203a, and the clamping plate 203c is fixed to the end of the toothed plate 203b.

[0038] Gear 203a is located on the lower part of the surface of threaded pipe 202a, and toothed plates 203b are located on both sides of threaded pipe 202a, both meshing with threaded pipe 202a. Clamping plates 203c are fixed on the side close to the seal 204. When threaded pipe 202a rotates, gear 203a will drive the two toothed plates 203b to move towards each other, and push the seal 204 inward through clamping plates 203c, so that the seal 204 is centered directly above the opening S, thus eliminating the need for manual alignment and greatly improving construction efficiency.

[0039] The positioning component 203 also includes a limiting block 203d, which is fixed to the top of the substrate 201. A sliding hole K is provided on the toothed plate 203b, and the limiting block 203d slides in the sliding hole K.

[0040] Each set of limiting blocks 203d has two that slide within the corresponding sliding holes K to limit the toothed plate 203b and prevent it from shifting during left and right movements. A spring is also fixed inside the sliding hole K, with the end of the spring fixed to the limiting block 203d. This spring applies a force to the toothed plate 203b towards the threaded tube 202a, thereby pressing the sealing frame 204a inward through the two sets of clamping plates 203c, so that the sealing frame 204a is centered directly above the opening S.

[0041] The positioning component 203 also includes a protective plate 203e and a connecting post 203f. The protective plate 203e is located outside the threaded tube 202a, and the two ends of the connecting post 203f are fixed to the protective plate 203e and the base plate 201, respectively.

[0042] The protective plate 203e is U-shaped and located above the clamping plate 203c. The protective plate 203e is fixed by two connecting posts 203f and is used to protect the gear 203a and the toothed plate 203b, preventing the gear 203a and the toothed plate 203b from being exposed to the air for a long time and being damaged by impacts from stones or other objects.

[0043] Example 3

[0044] Reference Figures 1-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the sealing element 204 includes a sealing frame 204a and a sealing ring 204b. The sealing frame 204a is located between the two substrates 201, and the sealing ring 204b is fixed to the bottom of the sealing frame 204a.

[0046] The sealing frame 204a is rectangular, and a rectangular ring is fixed to its inner bottom to fix the sealing ring 204b. The opening S is located inside the sealing frame 204a. When the sealing frame 204a moves downward, it can squeeze the sealing ring 204b, thereby improving the sealing effect between the sealing frame 204a and the floor slab 105 and preventing water from seeping into the opening S through the gap between the sealing frame 204a and the floor slab 105.

[0047] The sealing element 204 also includes a first plate 204c, a second plate 204d, and a stabilizing frame 204e. The first plate 204c is located on both sides of the top of the sealing frame 204a, and the second plate 204d is located on the top of the sealing frame 204a. The first plate 204c and the second plate 204d seal the top of the sealing frame 204a, and the stabilizing frame 204e is fixed to the bottom of the first plate 204c and the second plate 204d.

[0048] Two first plates 204c and two second plates 204d are each provided, symmetrically distributed in pairs, and both are triangular in shape. The four plates seal the opening at the top of the sealing frame 204a. The first plate 204c has a hole from which the top of the threaded rod 205b extends upward. Arc-shaped pressure blocks are fixed to both sides of the first plate 204c. Arc-shaped grooves are formed on both sides of the second plate 204d, fitting snugly with the arc-shaped pressure blocks. During installation, the two second plates 204d are first placed on top of the sealing frame 204a, then the two first plates 204c are installed. The arc-shaped pressure blocks and grooves limit and fix the two second plates 204d and the two first plates 204c, making the installation of the first plates 204c and second plates 204d more stable. The stabilizing frame 204e is used to limit and seal the first plate 204c and the second plate 204d. During installation, the stabilizing frame 204e is inserted into the top of the sealing frame 204a to limit and fix the sealing frame 204a, preventing the sealing frame 204a from shifting during use. Both the first plate 204c and the second plate 204d have holes for the standard section body 104 to be inserted. After the first plate 204c and the second plate 204d are installed, the standard section body 104 can be squeezed and fixed, thereby reducing the shaking that occurs at this position during use. The contact area between the first plate 204c and the second plate 204d is sealed to further prevent water penetration.

[0049] Support rods are fixed at the four corners of the inner wall of the sealing frame 204a. The ends of the support rods contact the first plate 204c and the second plate 204d to provide further support for the first plate 204c and the second plate 204d, thereby improving the stability of the installation of the first plate 204c and the second plate 204d.

[0050] The fastener 205 includes a fixing plate 205a, a threaded rod 205b, and a handle 205c. The fixing plate 205a is fixed to both sides of the sealing frame 204a. The threaded rod 205b is threadedly connected to the fixing plate 205a. The top end of the threaded rod 205b extends above the first plate 204c. The bottom end of the threaded rod 205b engages with the threaded tube 202a. The handle 205c is fixed to the top end of the threaded rod 205b.

[0051] The fixing plate 205a is rectangular and located below the first plate 204c. The top of the threaded rod 205b is fixed to the handle 205c by bolts. During installation, the top of the threaded rod 205b is first inserted through the hole on the first plate 204c, and then the handle 205c is fixed by bolts. This allows the threaded rod 205b to be rotated while the threaded rod 205b and the handle 205c move downwards and press against the first plate 204c through the handle 205c, thereby improving the stability and sealing of the first plate 204c installation.

[0052] The fastener 205 also includes a movable ring 205d, a slider 205e, and a plug 205f. The movable ring 205d slides inside the threaded tube 202a, the slider 205e is fixed around the movable ring 205d, the inner wall of the threaded tube 202a has a groove H that matches the slider 205e, the plug 205f is evenly distributed at the bottom of the movable ring 205d, and the top of the base plate 201 has a slot V that matches the plug 205f.

[0053] When the threaded rod 205b is threaded into the threaded tube 202a and moves downward, the bottom end of the threaded rod 205b will press the movable ring 205d downward, causing the insert rod 205f to be inserted into the slot V. This limits the movement of the threaded tube 202a, preventing it from rotating when connected to the threaded rod 205b and affecting installation efficiency. Multiple insert rods 205f and slots V are provided, evenly distributed in a ring at the bottom of the movable ring 205d to improve the limiting effect of the movable ring 205d. The slider 205e and the groove H are used to limit the movement of the movable ring 205d and prevent it from rotating during movement and use.

[0054] The fastener 205 also includes a return spring 205g, the two ends of which are fixed to the movable ring 205d and the base plate 201, respectively.

[0055] The return spring 205g applies an upward thrust to the movable ring 205d. When the threaded rod 205b moves upward, the return spring 205g pushes the movable ring 205d upward, causing the insert rod 205f to disengage from the slot V.

[0056] During use, when installing this waterproof structure, firstly, two base plates 201 are symmetrically fixed to both sides of the opening S on the floor slab 105 using bolts. Then, the sealing frame 204a is placed between the two base plates 201, and the sealing frame 204a is pushed in the center by two sets of clamping plates 203c so that the sealing frame 204a is positioned directly above the opening S, thus completing the pre-fixation of the sealing frame 204a. Next, two second plates 204d are placed on top of the sealing frame 204a, and then two first plates 204c are installed. The first plates 204c and second plates 204d are limited and fixed by arc-shaped pressure blocks and grooves to make the installation of the first plates 204c and second plates 204d more stable. At this time, the top of the threaded rod 205b extends above the first plate 204c, and the handle 205c is fixed to the top of the threaded rod 205b with bolts. Then, the threaded rod 205b is manually rotated. When in motion, the threaded tube 202a is rotated first, and the two toothed plates 203b are moved towards the sealing frame 204a through the gear 203a until the sealing frame 204a is fixed in position. Then, the threaded rod 205b is rotated, and the threaded rod 205b will be threaded into the threaded tube 202a. The bottom end of the threaded rod 205b will push the movable ring 205d downward, so that the movable ring 205d is inserted into the slot V. At this time, the threaded tube 202a cannot rotate. As the threaded rod 205b continues to be threaded into the threaded tube 202a, the threaded rod 205b continues to be threaded into the fixed plate 205a. The fixed plate 205a will be subjected to a downward force, which will drive the sealing frame 204a to move downward, thereby increasing the deformation of the sealing ring 204b and improving the sealing effect. At the same time, the first plate 204c can be squeezed by the handle 205c to improve the stability of the installation of the first plate 204c and the sealing effect.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
