Description

Technical Field

[0001] The utility model relates to the field of construction of wall - hanging wells, in particular to a construction device applicable to wall - hanging wells with multiple aperture diameters. Background Art

[0002] The inverse construction method is a commonly used construction method for wall - hanging wells at present. When using the inverse construction method for wall - hanging well construction, in order to ensure construction safety and quality, it is necessary to support the well - wall formwork. Each set of the currently commonly used traditional support structures can only be applicable to the construction of single - aperture - diameter wall - hanging wells. When facing wall - hanging wells with multiple aperture diameters, there are the following problems: 1. Before construction, multiple sets of support systems need to be made according to the size of the well, increasing the construction cost input; 2. When multiple sets of support systems are arranged simultaneously, the overly complex support system will occupy the limited construction space inside the well, affecting construction efficiency and quality; 3. After the traditional support structure is used, due to its strong pertinence and relatively fixed structure, it is not convenient for turnover use; 4. The traditional support structure adopts a longitudinal and transverse support grid system, with relatively dense longitudinal and transverse supports, and the installation of the supports is complex. Summary of the Invention

[0003] The purpose of the utility model is to provide a construction device applicable to wall - hanging wells with multiple aperture diameters.

[0004] The purpose of the utility model is realized as follows:

[0005] A construction device applicable to wall - hanging wells with multiple aperture diameters is characterized in that: it consists of vertical poles, horizontal support pipes, adjustable top supports, cross - beams, corbels, small ribs and formwork. Four vertical poles arranged in a square are vertically placed on the bottom plate of the wall - hanging well to be poured. Four horizontal support pipes placed vertically and horizontally in the horizontal direction are connected into a "well" shape through fasteners, and the four horizontal support pipes in the upper and lower layers are both fixed to the upper and lower parts of the vertical poles through fasteners; a circular formwork is provided at the well - wall of the wall - hanging well. Four completely identical, arc - shaped cross - beams with a central angle of 90 degrees are horizontally and spacedly placed outside the formwork. A number of small ribs perpendicular to the cross - beams are spacedly arranged between the inner wall of the cross - beams and the formwork. Corbels are provided on the outer walls of the small ribs and below the two ends of the horizontal support pipes. Adjustable top supports are provided at both ends of each horizontal support pipe. One end of the adjustable top support is inserted into the horizontal support pipe, and the other end of the adjustable top support is fixed on the corbel. The other end of the adjustable top support and the corbel jointly act to fixedly support and press the cross - beam inward, and support and press the small ribs and the formwork inward, preventing the concrete from squeezing and spreading the formwork when pouring the wall - hanging well.

[0006] The adjustable top support consists of a screw rod, an adjustable nut and a U - shaped top support. The outer wall of the adjustable nut is fixed at the port of the horizontal support pipe. The inner end of the screw rod is screwed from the outside to the inside and passes through the adjustable nut and then is inserted into the horizontal support pipe. A U - shaped top support is fixed at the outer end of the screw rod, and the inner wall of the U - shaped top support adheres to the outer wall of the cross - beam.

[0007] At the bottom of the four vertical poles, there are base plates for leveling the cribbing.

[0008] The cross beams are made of channel steel and bent into a quarter circle. Four cross beams can be spliced into a ring that fits the template with the smallest diameter.

[0009] The utility model consists of vertical poles, horizontal support pipes, adjustable top supports, cross beams, bracket feet, small ribs and templates. The cross beams transfer the load transmitted by the templates to the top supports and horizontal support poles, enabling the horizontal support poles to only bear axial forces without shear forces and bending moments, thereby improving the structural bearing capacity and stability; the small ribs are placed perpendicular to the cross beams to support and press the templates of the well walls of the wall-hanging wells, ensuring the structural stability.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. Four cross beams can be used for the construction of wall-hanging wells with different pore diameters. When facing wall-hanging wells with multiple pore diameters, there is no need to redesign and fabricate multiple sets of support frames, improving the construction efficiency and saving construction costs;

[0012] 2. When constructing wall-hanging wells with different pore diameters, it is necessary to adjust the distance between adjacent cross beams and the distance between opposite cross beams to change the radius of the circle formed by the four cross beams to match the well wall. At this time, the worker only needs to adjust the adjustable nut to adjust the length of the adjustable top support protruding, so that the horizontal support can closely adhere to the cross beam, ensuring the structural stability for subsequent construction;

[0013] 3. The structure is simple, the force is reasonable, the fabrication and installation are convenient, it is safe and reliable, the installation is convenient, it occupies a small space, and it occupies little space inside the well;

[0014] 4. It can be reused, has strong turnover ability and high economic benefits. Description of the Drawings

[0023] The following further elaborates on the patent of the present utility model in conjunction with the accompanying drawings and embodiments.

[0024] A construction device applicable to wall - hanging wells with multiple hole diameters is composed of a vertical pole 1, a horizontal support pipe 2, an adjustable jack 3, a cross beam 4, a bracket 5, a small rib 7, a fastener 8 and a formwork 6. Four vertical poles 1 arranged in a square are vertically placed on the bottom plate of the wall - hanging well 9 to be poured. Four horizontal support pipes 2 placed horizontally and vertically are connected into a "well" shape by fasteners 8, and the four horizontal support pipes 2 in the upper and lower layers are fixed to the upper and lower parts of the vertical pole 1 by fasteners 8; a circular formwork 6 is provided at the well wall of the wall - hanging well 9. Four identical, arc - shaped cross beams 4 with a central angle of 90 degrees are horizontally and spacedly placed outside the formwork 6. A number of small ribs 7 perpendicular to the cross beam 4 are spacedly arranged between the inner wall of the cross beam 4 and the formwork 6. Brackets 5 are provided below the two ends of the horizontal support pipe 2 on the outer wall of the small rib 7. An adjustable jack 3 is provided at both ends of each horizontal support pipe 2. One end of the adjustable jack 3 is inserted into the horizontal support pipe 2, and the other end of the adjustable jack 3 is fixed to the bracket 5. The other end of the adjustable jack 3 and the bracket 5 jointly act to fixedly hold the cross beam 4 and inwardly support and press the small rib 7 and the formwork 6 to prevent the formwork 6 from being squeezed and opened by the concrete when pouring the wall - hanging well 9.

[0025] The adjustable jack 3 is composed of a screw rod 301, an adjustable nut 302 and a U - shaped jack 303. The outer wall of the adjustable nut 302 is fixed to the port of the horizontal support pipe 2. The inner end of the screw rod 301 is screwed from the outside to the inside and passes through the adjustable nut 302 and then inserted into the horizontal support pipe 2. A U - shaped jack 303 is fixed to the outer end of the screw rod 301, and the inner wall of the U - shaped jack 303 adheres to the outer wall of the cross beam 4.

[0026] Cushion plates 11 for leveling are provided at the bottoms of the four vertical poles 1.

[0027] The cross beam 4 is made of channel steel and bent into a quarter - circle shape. The four cross beams 4 can be spliced into a ring that fits the formwork 6 with the smallest diameter.

[0028] Working principle:

[0029] 1. By adjusting the adjusting nut 302 to control the length of the screw rod 301 inserted into the horizontal support pipe 2, the combined length of the two adjustable jacks 3 and one horizontal support pipe 2 can be adjusted, realizing the change of the length of the horizontal support system. The U-shaped jack 33 and the corbel 5 act together to fix the cross beam 4, support and press the formwork of the wall of the hanging wall well 9, ensure the structural stability during the pouring of the wall of the hanging wall well 9, and prevent the concrete from squeezing and spreading the formwork 6.

[0030] 2. The cross beam 4 transfers the load transmitted by the formwork 6 to the adjustable jack 3 and the horizontal support pipe 2, so that the horizontal support pipe 2 only bears axial force without shear force and bending moment, thereby improving the structural bearing capacity and stability; the small ribs 7 are placed perpendicular to the cross beam 4, support and press the formwork 6 of the wall of the hanging wall well 9, and ensure the structural stability.

[0031] 3. When constructing the hanging wall well by the top-down method, first construct the large-diameter top protection cylinder section, and then construct the standard protection cylinder sections with gradually decreasing diameters downward until the last standard protection cylinder section with the smallest diameter is constructed; when constructing the hanging wall well 10 with different hole diameters, only need to adjust the distance between two adjacent cross beams 4, change the distance between the two opposite cross beams 4 to match the well wall 10, and adjust the extended length of the adjustable jack 3 by adjusting the adjustable nut 302, so that the adjustable jack 3 can closely adhere to the cross beam 4, ensure the structural stability, and facilitate the subsequent construction.

[0032] 4. After the construction of the top protection cylinder section is completed and reaches the design strength, continue to excavate to the elevation of the next standard protection cylinder section. Adjust the length of the horizontal support by adjusting the nut 302 to change the radius of the horizontal support. At the same time, adjust the distance between two adjacent cross beams 4, thereby changing the diameter enclosed by the four cross beams 4, install the formwork 4 to the appropriate position, support and press the formwork 4 of the wall of the hanging wall well 10, ensure the structural stability during the pouring of the wall of the hanging wall well 10, and prevent the concrete from squeezing and spreading the formwork 6.
