Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a formwork support system and support method for use in confined spaces. Background Technology

[0002] In modern building construction, the structural system of "double wall integration" of "underground continuous wall" and "external retaining wall" of underground structure, which maximizes the underground usable space within the land boundary, is particularly common.

[0003] However, due to common problems such as structural leakage, poor ventilation, and dampness in basements, an additional "inner lining wall" is often added after the "double wall integration." During the design phase, various factors are considered, including the overall project schedule and subsequent construction material costs (reducing the actual area of ​​waterproof membrane coverage). The "inner lining wall" is constructed along with the main underground structure, forming a closed structural cavity (with permeable pipes built into the floor slab). This allows condensation caused by temperature differences between the inside and outside, as well as water from the side walls caused by various factors, to be collected and discharged from the basement – ​​a sound architectural solution.

[0004] From this point on, a narrow, enclosed space (width b < 1000 mm) exists between the "underground continuous wall" and the "inner lining wall" resulting from the "double wall integration". When constructing the inner lining wall using traditional construction methods, it is difficult to remove the formwork due to the narrow, enclosed space, which cannot be accessed twice. If the traditional inner formwork is not removed and left inside for a long time, it will expand, rot, and scatter debris, which will block the pre-embedded drainage holes due to factors such as moisture. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a template support system and support method for small enclosed spaces. Precast blocks are stacked in the cavity between the inner lining wall and the diaphragm wall, and a grid-like drainage gap is created between multiple precast blocks using a partition structure, which facilitates the organized drainage function after condensate forms in the cavity later.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is a template support system for a confined, enclosed space, wherein the confined, enclosed space is located between a first structure and a second structure surrounding the periphery of the first structure, and the template support system comprises:

[0007] For stacking multiple prefabricated blocks in the small, enclosed space;

[0008] Anti-corrosion template for setting on the side of the second structure that is relatively close to the first structure;

[0009] A separation assembly for separating adjacent precast blocks to form a drainage gap between them, the separation assembly including a first separator connected to the anti-corrosion template and inserted between adjacent precast blocks, and a second separator disposed opposite to the first separator, the second separator being connected to the first structure and inserted between corresponding adjacent precast blocks.

[0010] A further improvement of the template support system for narrow enclosed spaces in this invention is that the width of the prefabricated block is adapted to the width of the narrow enclosed space, and both the first separator and the second separator are cross-shaped clips that can simultaneously separate the vertically adjacent prefabricated blocks and the horizontally adjacent prefabricated blocks.

[0011] A further improvement of the template support system for narrow enclosed spaces in this invention is that the number of the partition components is multiple, and the multiple partition components are distributed one-to-one between each of the four adjacent prefabricated blocks.

[0012] A further improvement of the template support system for confined spaces in this invention is that the cross-shaped clamp includes a connecting plate for connecting to the first structure or the anti-corrosion template and a cross-shaped clamp strip connected to one side of the connecting plate.

[0013] A further improvement of the template support system for confined spaces in this invention is that it also includes pads for selectively placing between adjacent precast blocks in conjunction with the partition component to maintain the size of the drainage gap.

[0014] A further improvement of the template support system for narrow enclosed spaces in this invention is that the template support system further includes a tie member that is correspondingly arranged with the partition component and crosses the drainage gap, and both the first partition component and the second partition component are provided with through holes for the tie member to pass through.

[0015] A further improvement of the template support system for confined spaces in this invention is that one end of the connector abuts against the first structure, and the other end passes through the anti-corrosion template and is fixed to the outer template of the second structure on the side relatively away from the first structure.

[0016] A further improvement of the template support system for confined spaces in this invention is that the precast block is a rectangular concrete precast block, and a rectangular frame is fixed to the outer periphery of the precast block.

[0017] A method for supporting templates in confined spaces includes the following steps:

[0018] Step 1: After the first structure is constructed, provide multiple second partitions and connect the multiple second partitions at intervals to the first structure;

[0019] Step 2: Provide multiple prefabricated blocks and stack them layer by layer from bottom to top, so that each prefabricated block abuts against the first structure. When stacking to the position of each second separator, the second separator is sandwiched between adjacent prefabricated blocks. At the same time, a first separator is provided and the position of the first separator relative to the second separator is inserted between adjacent prefabricated blocks and close to the side of the second structure.

[0020] Step 3: Provide an anti-corrosion template, place the anti-corrosion template at the design position of the second structure relatively close to the first structure, and connect multiple first separators to the anti-corrosion template.

[0021] A further improvement of the template support method for narrow enclosed spaces in this invention is that several pads are provided; during step 2, several pads are selectively placed between adjacent precast blocks to cooperate with the partition component to maintain the size of the drainage gap.

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. By stacking multiple precast blocks, the anti-corrosion template can be supported in a small, enclosed space. This allows the precast blocks to be used without affecting the construction period and improves construction efficiency. At the same time, the use of anti-corrosion templates prevents expansion and rotting after being exposed to moisture, which could then block the drainage outlets.

[0024] 2. By setting the separation component to create a drainage gap between adjacent precast blocks, a moisture-removing effect is achieved. Attached Figure Description

[0032] The template support system and its support method for small enclosed spaces according to the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figs. 1-4 As shown, a formwork support system for a confined space, the confined space being located between a first structure 4 and a second structure surrounding the periphery of the first structure 4, the formwork support system comprising:

[0034] Multiple prefabricated blocks 1 are used to stack in this small, enclosed space;

[0035] Anti-corrosion template 5 is used to be installed on the side of the second structure that is relatively close to the first structure 4;

[0036] A separating component 3 is used to separate adjacent precast blocks 1 to form a drainage gap 2 between adjacent precast blocks 1. The separating component 3 includes a first separating member connected to the anti-corrosion template 5 and inserted between adjacent precast blocks 1, and a second separating member disposed opposite to the first separating member. The second separating member is connected to the first structure 4 and inserted between corresponding adjacent precast blocks 1.

[0037] Specifically, multiple drainage pipes are pre-embedded at the bottom of the small, enclosed space.

[0038] Specifically, the anti-corrosion template 5 is made of steel plate.

[0039] By setting up the anti-corrosion template 5, it is possible to prevent the material from swelling and rotting after getting damp in the small enclosed space, which would then cause fragments to fall and block the drainage pipe pre-embedded at the bottom of the small enclosed space.

[0040] Preferably, the width of the precast block 1 is adapted to the width of the narrow enclosed space, and the first separator and the second separator are both cross-shaped clips that can simultaneously separate the upper and lower adjacent precast blocks 1 and the left and right adjacent precast blocks 1.

[0041] Preferably, there are multiple partition components 3, and the multiple partition components 3 are distributed one-to-one between each of the four adjacent prefabricated blocks 1.

[0042] By attaching the cross-shaped clip between four adjacent precast blocks 1, a grid-like drainage gap 2 is formed between the precast blocks 1, facilitating orderly drainage.

[0043] Preferably, the cross-shaped retainer includes a connecting plate 301 for connecting to the first structure 4 or the anti-corrosion template 5 and a cross-shaped retaining strip 302 connected to one side of the connecting plate 301.

[0044] Specifically, the connecting plate 301 is connected to the first structure 4 or the anti-corrosion template 5 by self-tapping screws. The self-tapping screws pass through the anti-corrosion template 5 and the connecting plate 301 in sequence and are connected to the precast block 1; or the self-tapping screws pass through the connecting plate 301 and are connected to the first structure 4.

[0045] Preferably, it also includes a pad for selectively placing the separator 3 between adjacent precast blocks 1 to maintain the size of the drainage gap 2.

[0046] By setting the spacer block to separate the two adjacent precast blocks 1 in the outermost two vertical rows, the amount of the separating component 3 used is reduced, the amount of construction work is reduced and the construction efficiency is improved.

[0047] Preferably, the template support system also includes a tie member 8 that is correspondingly provided to the partition component 3 and crosses the drainage gap 2. Both the first partition and the second partition are provided with through holes 303 for the tie member 8 to pass through.

[0048] By opening the through hole 303 on the first separator and the second separator for the pull member 8 to pass through, the connection stability of the pull member 8 is ensured.

[0049] Preferably, one end of the connector 8 abuts against the first structure 4, and the other end passes through the anti-corrosion template 5 and is fixed to the outer template 7 of the second structure on the side relatively away from the first structure 4.

[0050] Specifically, the tie member 8 is a rod at one end and a tie bolt with a U-shaped buckle at the other end. After the tie member 8 is installed, the reinforcing cage 6 is tied at the designed position of the second structure. The tie member 8 is avoided when tying the reinforcing cage 6. After the reinforcing cage 6 is tied, the outer formwork 7 is supported on the side of the reinforcing cage 6 that is relatively far away from the anti-corrosion formwork 5, in conjunction with the tie member 8.

[0051] A method for supporting an outer formwork 7 is provided, comprising the steps of: opening a hole in the outer formwork 7 for the tie member 8 to pass through; connecting the outer formwork 7 with the tie member 8 to the side of the reinforcing cage 6 that is relatively far away from the anti-corrosion formwork 5; setting multiple wooden back ribs on the side of the outer formwork 7 that is relatively far away from the reinforcing cage 6; and setting a steel pipe perpendicular to the wooden back ribs on the side of the multiple wooden back ribs that is relatively far away from the outer formwork 7 to clamp the multiple wooden back ribs; using the U-shaped buckle on the tie member 8 to fasten the steel pipe, thereby clamping the wooden back ribs between the outer formwork 7 and the steel pipe to ensure the verticality and stability of the outer formwork 7.

[0052] Specifically, after the outer formwork 7 is erected, a support member is erected on the side of the outer formwork 7 that is relatively far away from the reinforcing cage 6 to apply pressure to the outer formwork 7.

[0053] Specifically, the abutting component is a diagonal brace, with one end abutting against the mountain-shaped buckle and the other end connected to the existing structure.

[0054] Preferably, the precast block 1 is a rectangular concrete precast block 1, and a rectangular frame 101 is fixed to the outer periphery of the precast block 1.

[0055] By setting this precast block 1 to replace the support of traditional wooden formwork, it can be prefabricated in advance and stacked directly for construction when needed, without taking up construction time. At the same time, compared with the support of traditional wooden back ribs, it avoids expansion and rot after getting damp, thus preventing blockage of the drainage pipe.

[0056] A method for supporting templates in confined spaces includes the following steps:

[0057] Step 1: After the first structure 4 is constructed, a plurality of second partitions are provided, and the plurality of second partitions are connected at intervals to the first structure 4;

[0058] Step 2: Provide multiple prefabricated blocks 1 and stack them layer by layer from bottom to top, so that each prefabricated block 1 abuts against the first structure 4. When stacking to the position of each second separator, the second separator is sandwiched between adjacent prefabricated blocks 1. At the same time, a first separator is provided and the position of the first separator relative to the second separator is inserted between adjacent prefabricated blocks 1 and close to the side of the second structure.

[0059] Step 3: Provide anti-corrosion template 5, block the anti-corrosion template 5 at the design position of the second structure relatively close to the side of the first structure 4, and connect multiple first separators to the anti-corrosion template 5.

[0060] Preferably, a number of pads are provided; during step 2, the number of the pads are selectively placed between adjacent precast blocks 1 to cooperate with the partition assembly to maintain the size of the drainage gap.

[0061] Specifically, each layer of the prefabricated block 1 is stacked from left to right or from right to left, and a pad block is placed on top of the two outermost prefabricated blocks 1 when stacking to the outermost two of each layer.
