Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a sliding snap-on top support assembly. Background Technology

[0002] Tower-type modular support frames are construction support systems that bear vertical loads. They are characterized by fewer components, convenient assembly and disassembly, good load-bearing capacity, and high construction efficiency. In spaces with high formwork and large spans, their role in supporting and transmitting force is particularly significant, especially for supporting flat slabs. The top support is a crucial component of the tower-type modular support frame. It primarily bears the main joists and the forces transmitted from them, and finally, through the adjusting frames, standard frames, and bottom supports below the top support, the forces are transferred to the sturdy base.

[0003] Due to the large span and the length limitations of the main joist timber, a single support typically supports the joint of two main joists. To ensure safety, the two main joist timbers need to be precisely locked onto the support. On-site construction usually involves using freshly cut wooden wedges to secure the two timbers, which is not reusable, cumbersome, and requires multiple adjustments. Therefore, how to solve the problems of non-reusable wooden wedges, inconvenient wedge manufacturing and installation, wasted on-site operation time, and inconsistent wedge types, and how to create a support assembly with both assembly and reusability, is a pressing technical issue that needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to provide a sliding snap-on top support assembly to solve the technical problems existing in the background art.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A sliding snap-fit ​​top support assembly includes: a top support, a first prismatic wooden wedge, and a second prismatic wooden wedge. Two sliding components are symmetrically installed on the front and rear sides of the top of the top support. The first prismatic wooden wedge is installed at the top of the rear sliding component, and the second prismatic wooden wedge is installed at the top of the front sliding component. The two sliding components respectively drive the first and second prismatic wooden wedges to slide laterally. The top support is provided with two sets of pawl limiting components, which respectively... The lateral sliding of prismatic wooden wedge one and prismatic wooden wedge two is restricted; the prismatic wooden wedge one and prismatic wooden wedge two are arranged parallel to each other on their opposite sides and are respectively inclined to the direction of movement of prismatic wooden wedge one and prismatic wooden wedge two; it also includes: two main keel wooden blocks, the two main keel wooden blocks are spliced ​​together in a collinear manner, the splice of the two main keel wooden blocks is supported at the top of the top support, and the opposite sides of prismatic wooden wedge one and prismatic wooden wedge two are respectively pressed and adhered to the opposite sides of the two main keel wooden blocks.

[0007] Furthermore, the top support includes: a bottom supporting round tube and a support plate, both of which are made of steel. The support plate is a rectangular plate and is welded and fixed to the top of the bottom supporting round tube.

[0008] Furthermore, the sliding assembly includes: a sliding guide rail, a sliding cover, round rods, pulleys, and connecting shafts. The sliding guide rail is fixedly connected to the top of the support plate. The sliding guide rail is transversely through and open at the top. Several evenly distributed pulleys are transversely slidably connected inside the sliding guide rail. The top of each pulley is fixedly connected to a connecting shaft. The tops of the several connecting shafts are respectively fixedly connected to the bottom of the sliding cover. Two vertically arranged round rods are symmetrically fixedly connected to the left and right sides of the top center of the sliding cover. Both the first and second prismatic wooden wedges have two reserved through holes. The two reserved through holes cooperate with the two round rods respectively. By having four round rods from the two sliding assemblies pass through the two reserved through holes on the first and second prismatic wooden wedges respectively, the first and second prismatic wooden wedges are respectively installed on the tops of the two sliding covers.

[0009] Furthermore, the diameter of the reserved through hole is 2mm larger than the diameter of the round rod.

[0010] Furthermore, two end plates are symmetrically welded and fixed at both ends of the slide rail.

[0011] Furthermore, the inner cavity of the slide rail has a hexagonal cross-section and the hexagon is symmetrical front and back; the pulley has a hexagonal cross-section with the same cross-section as the inner cavity of the slide rail.

[0012] Furthermore, both the first and second prismatic wooden wedges are quadrangular prisms. The top support also includes: side baffles, which are rectangular steel plates. Four side baffles are provided and vertically and symmetrically welded and fixed to the left and right ends of the front and rear sides of the support plate. The rear end face of the first prismatic wooden wedge contacts and engages with the two rear side baffles, and the front end face of the second prismatic wooden wedge contacts and engages with the two front side baffles.

[0013] Furthermore, the pawl limiting assembly includes: a pawl, a spring, a rotating shaft, and a rotating bracket. The rotating bracket is fixedly connected to the lower outer side of the left end of the right side baffle of the two side baffles on the same front and rear sides. The pawl is rotatably connected to the rotating bracket via the rotating shaft. The middle of the inner end of the pawl and the left end of the corresponding side baffle are connected by a spring. Several evenly distributed serrated grooves are provided on both the front and rear sides of the sliding cover. The pawl engages with the serrated groove closest to it.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention secures the splice of two main keel timbers at the top of a top support, positioned between two prismatic wooden wedges. By driving the two wedges to move in opposite directions, the splice is locked in place. Two sets of ratchet limiting components restrict the lateral displacement of the wedges when they are engaged, simplifying construction. When the slide-type snap-fit ​​top support assembly is not needed, the entire assembly can be removed by releasing the ratchet limiting components, reducing construction time and improving efficiency. The two wedges are reusable, reducing material consumption. The entire slide-type snap-fit ​​top support assembly can hold main keel timbers of different widths, offering good applicability.

[0016] 2. This invention ensures the stability of the splicing points of multiple main keel timbers while maintaining the original load-bearing capacity of the top support, thus improving safety. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-4As shown, a sliding snap-fit ​​top support assembly includes: a top support 1, a prismatic wooden wedge 4, and a prismatic wooden wedge 5. Two sliding components 2 are symmetrically installed on the front and rear sides of the top of the top support 1. The prismatic wooden wedge 4 is installed at the top of the rear sliding component 2, and the prismatic wooden wedge 5 is installed at the top of the front sliding component 2. The two sliding components 2 respectively drive the prismatic wooden wedge 4 and the prismatic wooden wedge 5 to slide laterally. Two sets of ratchet limiting components 3 are provided on the top support 1. The lateral sliding of prismatic wooden wedge 1 and prismatic wooden wedge 2 is restricted respectively; the opposing sides of prismatic wooden wedge 1 and prismatic wooden wedge 2 are set parallel to each other and inclined to the direction of movement of prismatic wooden wedge 1 and prismatic wooden wedge 2 respectively; it also includes: two main keel wooden blocks, which are spliced ​​together in a collinear manner, and the splice of the two main keel wooden blocks is supported at the top of the top support 1, and the opposing sides of prismatic wooden wedge 1 and prismatic wooden wedge 2 are pressed tightly against the two opposite sides of the two main keel wooden blocks respectively.

[0024] In this embodiment, the top support 1 includes a bottom support tube 101 and a support plate 102. Both the bottom support tube 101 and the support plate 102 are made of steel. The support plate 102 is a rectangular plate and is welded and fixed to the top of the bottom support tube 101.

[0025] In this embodiment, the sliding assembly 2 includes: a sliding guide rail 201, a sliding cover 203, a round rod 204, pulleys 205, and a connecting shaft 206. The sliding guide rail 201 is fixedly connected to the top of the support plate 102. The sliding guide rail 201 is transversely through and has an open top. Several evenly distributed pulleys 205 are transversely slidably connected inside the sliding guide rail 201. The top of each pulley 205 is fixedly connected to a connecting shaft 206. The tops of the several connecting shafts 206 are respectively fixedly connected to the bottom of the sliding cover 203. The top of the sliding cover 203 is... Two vertically arranged round rods 204 are symmetrically fixedly connected on the left and right sides of the middle end. The first prismatic wooden wedge 4 and the second prismatic wooden wedge 5 are each provided with two reserved through holes. The two reserved through holes are respectively matched with the two round rods 204. The four round rods 204 in the two sliding components 2 are respectively inserted through the two reserved through holes on the first prismatic wooden wedge 4 and the two reserved through holes on the second prismatic wooden wedge 5 to install the first prismatic wooden wedge 4 and the second prismatic wooden wedge 5 on the top of the two sliding covers 203 respectively.

[0026] The length of the round rod 204 is greater than the length of the reserved through hole. The upper part of the round rod 204 is threaded with a nut, which restricts the vertical displacement of the prismatic wooden wedge 1 4 and the prismatic wooden wedge 2 5.

[0027] In this embodiment, the diameter of the reserved through hole is 2mm larger than the diameter of the round rod 204, which facilitates the quick installation and disassembly of the prism-shaped wooden wedge 1 4 and the prism-shaped wooden wedge 2 5.

[0028] In this embodiment, two end plates 202 are symmetrically welded and fixed at both ends of the slide rail 201. The end plates 202 can restrict the pulley 205 from slipping out of the slide rail 201.

[0029] In this embodiment, the inner cavity of the slide rail 201 has a hexagonal cross-section and the hexagon is symmetrical front and back; the cross-section of the pulley 205 is the same hexagonal as the inner cavity of the slide rail 201, so that the pulley 205 can only slide laterally.

[0030] In this embodiment, both the first prismatic wooden wedge 4 and the second prismatic wooden wedge 5 are quadrangular prisms. The top support 1 also includes: side baffles 103, which are rectangular plates made of steel. Four side baffles 103 are provided, and the four side baffles 103 are vertically and symmetrically welded and fixed to the left and right ends of the front and rear sides of the support plate 102. The rear end face of the first prismatic wooden wedge 4 contacts and engages with the two rear side baffles 103, and the front end face of the second prismatic wooden wedge 5 contacts and engages with the two front side baffles 103. The four side baffles 103 can distribute the force on the sliding component 2 to a certain extent, thereby improving the stability and service life of the entire device.

[0031] In this embodiment, the pawl limiting assembly 3 includes: a pawl, a spring, a rotating shaft, and a rotating bracket. The rotating bracket is fixedly connected to the lower outer side of the left end of the right side baffle 103 of the two side baffles 103 on the same side. The pawl is rotatably connected to the rotating bracket via the rotating shaft. The middle of the inner end of the pawl and the left end of the corresponding side baffle 103 are connected by a spring. Several evenly distributed serrated grooves are provided on both the front and rear sides of the sliding cover 203. The pawl engages with the serrated groove on the side closest to it. The number of pawl limiting assemblies 3 can be two or four. They can be set on the two opposite side baffles 103 on the right side according to actual engineering requirements, or the four pawl limiting assemblies 3 can be set on the four side baffles 103 respectively.

[0032] Working principle: By placing the joint of the two main keel timbers at the top of the support and between prismatic wooden wedges 4 and 5, and hammering prismatic wooden wedges 4 and 5 in opposite directions, the gap between the two wedges gradually decreases, thus securing the joint of the main keel timbers. Two sets of ratchet limiting components 3 can further secure the two main keel timbers by clamping them between prismatic wooden wedges 4 and 5. At the splicing point, the lateral displacement of prismatic wooden wedges 1-4 and prismatic wooden wedge 2-5 is restricted respectively, making construction operation convenient; when this chute snap-on top support assembly is not needed, the entire chute snap-on top support assembly can be removed simply by releasing the restriction function of the two sets of ratchet limiting components 3, reducing construction time and improving efficiency; prismatic wooden wedges 1-4 and prismatic wooden wedge 2-5 can be reused, reducing material consumption; the entire chute snap-on top support assembly can clamp main keel timber of different widths, making it highly adaptable.
