Description

Technical Field

[0001] The utility model relates to the technical field of construction of prefabricated buildings and large-scale logistics storage centers, and in particular to the pouring operation of large-span, ultra-high and ultra-large concrete structures at the construction site of prefabricated buildings, and specifically is a frame-type concrete distribution bracket suitable for narrow spaces. Background Art

[0002] In prefabricated industrial buildings, especially in the construction of multi-story factories or multi-story warehouses, it is common to encounter the use of steel truss floor decks (no scaffolding support is required), prefabricated composite beams, large-span, super-high and super-large cast-in-place independent columns and shear wall structures; for these super-high and super-large concrete structures, the amount of concrete pouring is often very large. At this time, if the space is limited or the location is inaccessible to concrete pump trucks or exceeds the operating radius of concrete pump trucks, it is necessary to temporarily build scaffolding to place the pump pipes, but the temporary scaffolding also has problems, such as the cost problems caused by repeated installation and disassembly, and the form of temporary scaffolding is not uniform, which is also unreliable and impractical for the placement of pump pipes. Therefore, how to meet the concrete pouring operations of these cast-in-place structures while ensuring quality and quantity while reducing costs and increasing efficiency is a great challenge. Summary of the invention

[0003] The purpose of the utility model is to overcome the above-mentioned defects and to provide a frame-type concrete placing bracket which is easy to arrange quickly in a narrow space, can be reused and is suitable for high-altitude operations.

[0004] In order to achieve the above object, the utility model is achieved as follows:

[0005] A frame type concrete placing support suitable for a narrow space comprises a frame type frame 1, a pump pipe 14, a ladder 5 and a lifting lug 15; the pump pipe 14 is a rigid pipe and is vertically arranged in the frame type frame 1, and a pump pipe output port and a pump pipe input port are respectively arranged at the top and bottom of the pump pipe 14; the frame type frame 1 comprises columns 3 and beams, the columns 3 are vertically arranged, and each column 3 is welded and connected with the beam, and at least three beams are arranged along the upper part, middle part and lower part of the column 3; the side projection of the frame type frame 1 is a trapezoid, and the inclination angles of its front end face, left side face and right side face are 83°~87°, and the inclination angle of its rear end face is 65°~70°; the ladder 5 is arranged on the rear end face of the frame type frame 1, and the lifting lugs 15 are arranged in pairs and located on the top surface of the frame type frame 1.

[0006] The above-mentioned frame-type concrete distribution support proposed by the utility model has a main body of a frame-type frame 1 in the shape of a quadrangular pyramid, which can effectively lower the center of gravity of the entire support. At the same time, a lifting lug 15 is arranged on the top of the frame-type frame 1, so that the entire frame can be lifted when necessary to achieve the purpose of rapid arrangement; further, a ladder 3 is arranged on the outside of the frame-type frame 1 to facilitate operators to climb up to work. On this basis, a rigid pump pipe 14 is vertically arranged in the frame-type frame 1, so that the entire support can be used as the first-line auxiliary equipment for concrete distribution operations, and can implement large-scale concrete distribution operations in a small space where there are only a small number of operators and pump trucks cannot reach.

[0007] Furthermore, the frame-type concrete distribution support suitable for a narrow space also includes a hose bracket 10 which can rotate 360° with the pump pipe 14 as the axis. The hose bracket 10 is sleeved on the pump pipe 14 through the sleeve 7. The hose bracket 10 is used to support a distribution hose 11; the distribution hose 11 is a rubber hose, which is sealed and connected to the output port of the pump pipe 14 through a swivel joint 9, and the input port of the pump pipe 14 is connected to the concrete raw material supply end, so that the concrete raw material is transported to the target site through the pump pipe 14 and the distribution hose 11, and the operator can pull the swivel bracket 10 on the ground through a traction rope and rely on the swivel bracket 10 to make the distribution hose 11 rotate with it, thereby expanding the distribution range of the concrete.

[0008] Furthermore, the above-mentioned frame-type concrete placing support suitable for a narrow space also includes a rest platform 4 made of a steel plate, which is placed on the crossbeam of the frame-type frame 1 and welded to the crossbeam; the rest platform 4 is used for operators to observe or rest at different heights in the frame-type frame 1 after climbing up the ladder 5.

[0010] Figure 2 It is a front view of the frame type concrete placing support shown in the embodiment. DETAILED DESCRIPTION

[0011] The present invention is further described below through specific embodiments.

[0012] like Figure 1 , Figure 2A frame type concrete material placing support comprises a frame type frame body 1, the frame type frame body 1 comprises columns 3 and beams, the columns 3 have four columns and are arranged vertically, and the beams are arranged in a ring shape, the columns (3) are welded to the beams, and four beams are arranged along the upper part, the middle part and the lower part of the columns (3), and the spacing distances of the four circularly arranged beams from the ground to the top are 3000mm, 3000mm, 3000mm and 1000mm respectively; the side shadow of the frame type frame body 1 is a trapezoid, the bottom spacing is 3000mm*6000mm, the inclination angles of the front end face, the left side face and the right side face are 83°~87°, and the inclination angle of the rear end face is 65°~70°; thus, the formed frustum shape with four edges helps to lower the center of gravity of the entire support. Furthermore, a steel plate is welded to each of the four annular cross beams of the frame-type frame body 1 to form a resting platform 4 , and the resting platform 4 is used for operators to observe or rest at different heights of the frame-type frame body 1 .

[0013] A lifting lug 15 is also provided on the top of the frame support 1 formed above, which is used for lifting the entire device. At the same time, a ladder 3 is provided on the side of the frame support 1, specifically on the inclined outer surface, so that operators can enter the rest platforms 4 at different heights of the frame support 1 via the ladder 3; considering the life safety of the operators, a safety fence 6 is provided on the rest platform 4.

[0014] The frame-type concrete distribution support also includes a pump pipe 14 and a distribution hose 11. The pump pipe 14 is a rigid pipe welded from metal pipes and is vertically arranged in the frame-type frame 1. In order to facilitate the installation of the pump pipe 14, a through hole 13 is opened on the rest platform 4 and a pump pipe clamp 2 is arranged at the hole mouth. Then, the pump pipe 14 passes through each platform 14 through the clamp 2 and is fastened by the clamp 2. In this way, even when the entire support is hoisted, the pump pipe 14 can be reliably fixed and supported. A pump pipe output port and a pump pipe input port are respectively arranged at the top and the bottom of the pump pipe 14; wherein, the pump pipe output port of the pump pipe 14 is connected to the material distribution hose 11 through a swivel joint 9, so that the material distribution hose 11 can rotate 360 ​​degrees without affecting the pump pipe 14, so that the concrete transported through the pump pipe 14 can be transported to the target area through the material distribution hose 11; the pump pipe output port of the pump pipe 14 is used to be connected to the concrete raw material end (for example, a pump truck that cannot approach the pouring site) through a conveying pipeline.

[0015] On the basis of the above, in order to facilitate the control of the direction of the material distribution hose 11, the frame type concrete material distribution support further includes a hose bracket 10, which is a cantilever truss structure. Specifically, it includes a horizontal bar with a length of more than 7000mm and a supporting diagonal bar located below the horizontal bar and connected to the horizontal bar and the sleeve 7 respectively. A reinforcing rib is arranged between the supporting diagonal bar and the horizontal bar to prevent the horizontal bar from bending downward due to load bearing. Between the horizontal bar and the material distribution hose 11, a pipe bracket 12 is arranged. The pipe bracket 12 is welded on the horizontal bar, and its top is an arc-shaped groove for accommodating the material distribution hose 11. The sleeve 7 is used to rotatably connect the hose bracket 10 with the pump pipe 14. It is vertically arranged at the top layer of the frame type frame 1 and sleeved on the outside of the pump pipe 14. A pump pipe sheath 8 is also added between the pump pipe 14 and the sleeve 7. The pump pipe sheath 8 is made of elastic material (such as hard rubber); in this way, premature wear of the pump pipe 14 caused by the rotation of the sleeve 7 can be avoided. During actual use, the operator pulls the hose bracket 10 on the ground through a traction rope connected to the hose bracket 10 to make it rotate around the pump tube 14 as the axis, thereby driving the cloth hose 11 to follow and then rotating the cloth hose 11 to the target area.

[0016] It can be seen from the above embodiments that the utility model proposes a simple, lightweight and reusable concrete distribution bracket, which can be quickly deployed to the target area through common tower cranes, electric hoists and other lifting tools on the construction site. In this way, when the pump truck cannot reach the operating area, large-scale concrete distribution operations can be carried out quickly and conveniently.
