Description
Technical Field
[0001] The utility model relates to the technical field of building construction tools, in particular to a flow guide device used for pouring concrete by a building construction machine. Background Art
[0002] With the growth of urban population and the limited land resources, super high-rise buildings can effectively utilize limited land resources and improve land utilization efficiency. The main structure of super high-rise buildings is usually in the form of core tube shear wall plus outer frame steel column. During the construction process, the main structure is often constructed first and the outer frame structure is lagging behind. The core tube shear wall must be constructed first, so climbing formwork, climbing frame and other construction platforms must be used first.
[0003] The building construction machine is equipped with a multi-layer hanging operating platform, which can simultaneously meet the construction methods of pouring concrete of the lower wall columns and binding steel bars of the upper layer. The concrete is pumped to the concrete placing machine on the top floor through a ground pump, and then the concrete placing machine transports the concrete to the floors below that need to be poured. Therefore, the building construction machine has become a commonly used super-high-rise construction equipment.
[0004] The core tube shear wall in super high-rise buildings is often constructed using the super-layer steel bar tying method. Super-layer steel bar tying is the process of tying the upper layer of steel bars after the poured concrete has initially set and has the capacity to bear the upper construction load. At least two layers of steel bars can be tied at one time.
[0005] However, when pouring the super-layer tied steel bars, since the tied steel bars are designed for super-layers and based on the load-bearing requirements of the core tube shear wall, the steel bars at this position are dense, and the concrete placing machine hose cannot extend through the upper steel bars to the position below that needs to be poured. Concrete can only be poured directly downward at the node position where the upper steel bars are tied, that is, the junction of the tied steel bars and the untied steel bars. Since the steel bars at the position to be poured are dense and the concrete is poured downward from an excessively high position, the concrete cannot fully fill the area to be poured surrounded by the steel molds arranged outside the steel bars, resulting in holes in the poured wall, and the excessive height will cause the coarse aggregate in the concrete to be deposited, which will cause uneven concrete composition, that is, concrete segregation. In addition, the concrete will contaminate the steel bars at the position to be poured above the pouring position and even the untied steel bars during the downward pouring process, affecting the quality of the steel bars and the quality of subsequent pouring and forming, and reducing the construction quality. Utility Model Content
[0006] The purpose of the utility model is to provide a flow guide device for pouring concrete by a building construction machine, so as to solve the problem that the concrete placing machine of the existing building construction machine cannot directly extend the hose to the lower position to be poured and can only pour at a higher position, resulting in holes in the wall, concrete segregation and contamination of steel bars in the unpoured position.
[0007] In order to achieve the above-mentioned purpose, the utility model provides a flow guide device for pouring concrete by a building construction machine, wherein the building construction machine comprises a steel mold which is arranged on the periphery of a wall to be poured and can be lifted, and the flow guide device comprises a bottom plate, a flow guide plate, a baffle plate and two support plates;
[0008] The bottom plate is arranged horizontally and fixed to the top of the steel mold; the bottom plate is defined to have a first direction and a second direction perpendicular to each other in the horizontal direction, the guide plate is arranged obliquely downward, and its bottom surface is fixedly connected to one end of the upper surface of the bottom plate in the first direction, and the angle between the guide plate and the bottom plate is less than ninety degrees;
[0009] The orthographic projection area of the guide plate extends toward the outer side of the bottom plate in a first direction;
[0010] The baffle is vertically arranged, and its bottom surface is fixedly connected to the top surface of the guide plate;
[0011] Two support plates are arranged opposite to each other and are arranged between the bottom plate and the guide plate, and are located at two ends of the bottom plate in the second direction, and the two support plates are fixedly connected to the bottom plate and the guide plate;
[0012] The support plate is provided with a plurality of connection holes penetrating through the surfaces on both sides thereof.
[0013] Furthermore, it also includes a plurality of reinforcing plates arranged at intervals, wherein the reinforcing plates are all arranged parallel to the supporting plates and are arranged between two supporting plates in sequence along the second direction, and the reinforcing plates are all fixedly connected to the bottom plate and the guide plate.
[0014] Furthermore, it is characterized in that the size of the bottom plate in the first direction is smaller than or equal to the size of the top surface of the steel mold.
[0015] Further, the size of the baffle in the second direction is equal to the size of the guide plate in the second direction;
[0016] The dimension of the guide plate in the second direction is equal to the dimension of the bottom plate in the second direction.
[0017] Furthermore, the support plate is a triangular plate, the top of which is flush with the top of the guide plate, and the size of the bottom of the support plate in the first direction is the same as that of the bottom plate.
[0018] Furthermore, the cross-sectional shape of the reinforcing plate is the same as the cross-sectional shape of the supporting plate.
[0019] Furthermore, the bottom plate is provided with a plurality of fixing holes penetrating the upper and lower surfaces thereof.
[0020] Furthermore, the vertical dimension of the baffle is greater than or equal to 30 mm.
[0021] Compared with the prior art, the utility model provides a flow guide device for pouring concrete in a building construction machine, which has the following beneficial effects:
[0022] The flow guide device for pouring concrete by the building construction machine comprises a bottom plate, a flow guide plate, a baffle plate and two support plates. The flow guide plate arranged obliquely downward can guide the concrete to flow downward, and the bottom plate and the support plate are arranged so that the flow guide plate always maintains an oblique downward angle and can be fixedly connected to the steel mold. The flow guide device for pouring concrete by the building construction machine is combined with the steel mold, which changes the existing pouring method of the building construction machine.

The guide device is correspondingly higher than the top surface of the cast wall, and the hose of the concrete placing machine is extended to the top of the guide device. Under the guidance of the guide plate, the concrete falls to the top surface of the cast wall until it is the same height as the steel mold. The building machine drives the steel mold to rise so that it is slightly higher than the top surface of the cast position, continues to cast and repeats this process to complete the casting of the tied steel bars, thereby avoiding the problems of holes in the wall, concrete segregation and contamination of uncast steel bars caused by the casting position being too high, and ensures the construction quality. In addition, the guide device for casting concrete by the building machine prevents the concrete falling on the guide plate from overflowing or splashing during casting through the vertically arranged baffle, thereby improving the construction efficiency and construction safety.

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] like Figure 1 to Figure 4 As shown, a flow guide device 100 for pouring concrete by a building construction machine according to an embodiment of the utility model, the building construction machine includes a steel mold 200 which is arranged on the periphery of a wall 300 to be poured and can be lifted, and is characterized in that it includes a bottom plate 1, a flow guide plate 2, a baffle plate 3 and two support plates 4; the bottom plate 1 is horizontally arranged and fixed to the top of the steel mold 200; it is defined that the bottom plate has a first direction X and a second direction Y which are perpendicular to each other in the horizontal direction, the flow guide plate 2 is inclined downward, and its bottom surface is aligned with one end of the upper surface of the bottom plate 1 in the first direction X. The guide plate 2 is fixedly connected to the bottom plate 1, and the angle between the guide plate 2 and the bottom plate 1 is less than ninety degrees; the orthographic projection area of the guide plate 2 extends toward the outside of the bottom plate 1 in the first direction X; the baffle 3 is vertically arranged, and its bottom surface is fixedly connected to the top surface of the guide plate 2; two support plates 4 are arranged opposite to each other and are arranged between the bottom plate 1 and the guide plate 2, and are located at both ends of the bottom plate 1 in the second direction Y, and the two support plates 4 are fixedly connected to the bottom plate 1 and the guide plate 2; the support plate 4 is provided with a plurality of connection holes 41 that pass through the surfaces on both sides thereof.
[0030] Based on the above technical solution, the guide device 100 guides the concrete in the concrete placing machine hose of the building construction machine to flow downward to the position to be poured through the guide plate 2 arranged obliquely downward, and a bottom plate 1 is arranged horizontally and the bottom surface of the guide plate 2 is fixedly connected to one end of the upper surface of the bottom plate 1 in the first direction X, so that the guide device 100 can be stably fixed on the top of the steel mold 200; and the orthographic projection area of the guide plate 2 extends to the outside of the bottom plate 1 in the first direction X to prevent the angle between the guide plate 2 and the bottom plate 1 from being too large, thereby avoiding the wall quality problem caused by the high concrete pouring position; because the concrete is heavy , the impact force caused by the fall is strong. In order to prevent the guide plate 2 from bending, two opposite support plates 4 are provided, which are located between the bottom plate 1 and the guide plate 2, and are respectively provided at both ends of the bottom plate 1 in the second direction Y to evenly bear the impact force; a baffle is also vertically arranged, and the bottom surface of the baffle is fixedly connected to the top surface of the guide plate, so that the concrete falling onto the guide plate surface is blocked by the baffle when splashing or overflowing excessively; in addition, in order to facilitate the connection of the guide device 100 with the adjacent guide device to form a complete guide setting, a plurality of connection holes 41 penetrating the surfaces on both sides thereof are opened on the support plate 4 for fastener connection.
[0031] Preferably, since the angle between the guide plate 2 and the baffle 3 is an obtuse angle, it is convenient to bend and form the whole plate. Therefore, the guide plate 2 and the baffle 3 in this embodiment are bent and formed by a whole plate, and the bending angle is determined by the angle between the base plate 1 and the guide plate 2 to ensure that when the guide plate 2 is fixedly connected to the base plate 1, the baffle 3 is vertically arranged. The integrated design speeds up the processing and production process, and makes the connection position of the baffle 3 and the guide plate 2 without gap, which is beneficial for the baffle 3 to achieve its function of preventing concrete from overflowing and splashing.
[0032] Furthermore, since the support plates 4 are disposed at both ends of the base plate 1 in the second direction Y, if the size of the guide plate 2 in the second direction Y is set larger, the middle section of the guide plate 2 in the second direction Y lacks support, and the middle section is prone to bending and deformation, affecting the guide effect. Therefore, the guide device 100 also includes a plurality of spaced reinforcement plates (not shown in the figure), which are arranged parallel to the support plates 4 and are arranged in sequence between the two support plates 4 along the second direction Y. The reinforcement plates are fixedly connected to the base plate and the guide plate to support the middle section of the guide plate 2 in the second direction Y.
[0033] Furthermore, if Figure 4 As shown, the size of the bottom plate 1 in the first direction X is smaller than or equal to the size of the top surface of the steel mold 200 to ensure that the setting of the bottom plate 1 will not interfere with other devices and the bottom plate 1 can be fully stabilized on the steel mold 200.
[0034] Furthermore, if Figure 1 As shown, in order to facilitate the processing, production, packaging and transportation of the guide device 100, the size of the baffle 3 in the second direction Y is equal to the size of the guide plate 2 in the second direction Y; the size of the guide plate 2 in the second direction Y is equal to the size of the bottom plate 1 in the second direction Y, so that the sizes of the bottom plate 1, the guide plate 2 and the baffle 3 in the second direction Y are consistent, which is convenient for the division of the original plate, the connection positioning and packaging and transportation between the bottom plate 1, the guide plate 2 and the baffle 3.
[0035] Furthermore, if Figure 1 , Figure 2 and Figure 4As shown, in order to fully support the surface of the guide plate 2, the support plate 4 is a triangular plate, the top of which is flush with the top of the guide plate 2, and the bottom of the support plate 4 has the same size as the bottom plate 1 in the first direction X, so as to achieve the purpose of matching the triangular shape of the support plate 4 with the shape of the cross-sectional gap formed between the bottom plate 1 and the guide plate 2, so that the edge of the support plate 4 connected to the guide plate 2 is completely in contact with the guide plate 2 in the first direction X, achieving full support, and the bottom of the support plate 4 has the same size as the bottom plate 1 in the first direction X, which is beneficial to the stability of the overall structure and balanced force.
[0036] Furthermore, the cross-sectional shape of the reinforcing plate is the same as that of the supporting plate 4, which is convenient for simplifying the processing and production steps. Preferably, in order to improve the processing and production efficiency, the supporting plate 4 is used as the reinforcing plate in this embodiment.
[0037] Furthermore, if Figure 3 As shown, in order to facilitate the fixation of the guide device 100 and the steel mold 200, the base plate 1 is provided with a plurality of fixing holes 11 penetrating the upper and lower surfaces thereof. The fixing holes 11 are arranged at intervals and matched with the existing holes on the steel mold 200, so as to facilitate the addition of fasteners for connection and fixation.
[0038] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, in order to ensure that the baffle 3 prevents the concrete from overflowing or splashing when it falls on the guide plate 2, the size of the baffle 3 in the vertical direction is greater than or equal to 30 mm. If the size is too small, it cannot prevent the concrete from splashing or overflowing, and too small a size will increase the difficulty of processing and production and increase production costs.
[0039] The working process of the utility model is as follows: the flow guide device 100 is fixedly connected to the top of the steel mold 200 through the fixing hole 11 of the bottom plate 1, and the surface of the flow guide plate 2 used for the flow guide work is directed to the position to be poured, and the top of the steel mold 200 is higher than the top surface of the poured wall 300, so as to ensure that the steel mold 200 encloses the position to be poured. The flow guide device 100 is usually arranged adjacent to each other in plurality, and adjacent flow guide devices 100 are fixedly connected through the connecting holes 41 opened on the support plate 4. The placing machine hose of the external building construction machine extends to the top of the flow guide plate 2, and the placing machine hose transports concrete to the plate surface of the flow guide plate 2. The downwardly inclined setting of the flow guide plate 2 guides the concrete to flow to the position to be poured for pouring. When the top surface of the poured position is nearly flush with the top surface of the steel mold, the steel mold is lifted by the building machine, and the top of the steel mold 200 is higher than the poured position to ensure smooth pouring. The above process is repeated until the pouring is completed at the position where the steel bars have been tied.
[0040] In summary, the embodiment of the utility model provides a flow guide device 100 for pouring concrete by a building construction machine, which is formed by setting a bottom plate 1, a flow guide plate 2, a baffle plate 3 and a support plate 4 to form a flow guide device 100 with a simple structure and easy to use. The flow guide plate 2 is arranged downwardly to guide the concrete to flow to the position to be poured. The flow guide device 100 can be stably placed and fixedly connected to the steel mold 200 through the fixed connection between the bottom plate 1 and the flow guide plate 2; two support plates 4 arranged opposite to each other are arranged between the bottom plate 1 and the flow guide plate 2 and are located at the bottom plate 1 at the second At both ends in direction Y, support for the guide plate 2 is achieved, the baffle 3 is vertically arranged, and its bottom surface is fixedly connected to the top surface of the guide plate 2 to prevent concrete splashing and overflowing; and on this basis, a reinforcing plate is arranged to further enhance the support for the guide plate 2; the design and introduction of the guide device facilitates the implementation of a new concrete pouring construction method, changes the layout position of the hose of the building machine's placing machine, and effectively solves the problems of holes in the wall, concrete segregation and pollution of uncast steel bars caused by the excessively high pouring position in the prior art, thereby improving the quality of engineering construction.
[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
